    To identify the underlying genetic defect in a Chinese family affected with autosomal dominant congenital nuclear cataract. A four-generation Chinese family with inherited nuclear cataract phenotype was recruited. Detailed family history and clinical data were recorded. All reported nuclear cataract-related candidate genes were screened for causative mutations by direct DNA sequencing. Effects of amino acid changes on the structure and function of protein were predicted by bioinformatics analysis. All affected individuals in this family showed nuclear cataracts. Sequencing of the candidate genes revealed a heterozygous c.559C>T change in the coding region of the major intrinsic protein (MIP), which caused a substitution of highly conserved arginine by cysteine at codon 187 (p.R187C). This mutation co-segregated with all affected individuals and was not observed in unaffected family members or 110 ethnically matched controls. Bioinformatics analysis showed that the mutation was predicted to affect the function and secondary structure of MIP protein. This study identified a novel disease-causing mutation p.R187C in MIP in a Chinese cataract family, expanding the mutation spectrum of MIP causing congenital cataract.

    To investigate a novel insertion variant of CRYGD identified in a Chinese family with nuclear congenital cataract. A Chinese family with congenital nuclear cataract was recruited for the mutational screening of candidate genes by direct sequencing. Recombinant N-terminal Myc tagged wildtype or mutant CRYGD was expressed in HEK293T cells. The expression pattern, protein solubility and subcellular distribution were analyzed by western blotting and immunofluorescence. A novel insertion variant, c.451_452insGACT, in CRYGD was identified in the patients. It causes a frameshift and a premature termination of the polypeptide to become Y151*. A significantly reduced solubility was observed for this mutant. Unlike wildtype CRYGD, which existed mainly in the cytoplasm, Y151* was mis-located in the nucleus. We have identified a novel mutation, c.451_452insGACT, in CRYGD, which is associated with nuclear cataract. This is the first insertion mutation of CRYGD found to cause autosomal dominant congenital cataract. The mutant protein, with loss of solubility and localization to the nucleus, is hypothesized to be the major cause of cataract in these patients.

    To identify the genetic defect associated with autosomal dominant congenital nuclear cataract in a Chinese family. Family history and phenotypic data were recorded, and the phenotypes were documented by slit lamp photography. The genomic DNA was extracted from peripheral blood leukocytes. All the exons and flanking intronic sequences of CRYGC and CRYGD were amplified by polymerase chain reaction (PCR) and screened for mutation by direct DNA sequencing. Structural models of the wild type and mutant gammaC-crystallin were generated and analyzed by SWISS-MODEL. Sequencing of the coding regions of CRYGC and CRYGD showed the presence of a heterozygous C>A transversion at c.327 of the coding sequence in exon 3 of CRYGC (c.327C>A), which results in the substitution of a wild type cysteine to a nonsense codon (C109X). One and a half Greek key motifs at the COOH-terminus were found to be absent in the structural model of the mutant truncated gammaC-crystallin. A novel nonsense mutation in CRYGC was detected in a Chinese family with consistent autosomal dominant congenital nuclear cataract, providing clear evidence of a relationship between the genotype and the corresponding cataract phenotype.

    To identify the genetic defects associated with autosomal dominant congenital nuclear cataract in a Chinese family. Clinical data were collected, and the phenotypes of the affected members in this family were recorded by slit-lamp photography. Genomic DNA was isolated from peripheral blood. Mutations were screened in cataract-associated candidate genes through polymerase chain reaction (PCR) analyses and sequencing. Structural models of the wild-type and mutant alphaB-crystallin were generated and analyzed by SWISS-MODEL. Mutation screening identified only one heterozygous G-->A transition at nucleotide 32 in the first exon of alphaB-crystallin (CRYAB), resulting in an amino acid change from arginine to histidine at codon 11 (R11H). This mutation segregated in all available affected family members but was not observed in any of the unaffected persons of the family. The putative mutation disrupted a restriction site for the enzyme, Fnu4HI, in the affected family members. The disruption, however, was not found in any of the randomly selected ophthalmologically normal individuals or in 40 unrelated senile cataract patients. Computer-assisted prediction suggested that this mutation affected the biochemical properties as well as the structure of alphaB-crystallin. These results supported the idea that the novel R11H mutation was responsible for the autosomal dominant nuclear congenital cataract in this pedigree.

    To identify the genetic defect in a three-generation Chinese family with congenital cataracts. The phenotype of a three-generation Chinese family with congenital cataract was recruited. Detailed family history and clinical data of the family were recorded. Candidate genes sequencing was performed to screen out the disease-causing mutation. Bioinformatics analysis was performed to predict the function of mutant gene. The phenotype of the family was identified as nuclear cataract. Direct sequencing revealed a c.161 G > T transversion in exon 1 of crystallin alpha-A (CRYAA). This mutation co-segregated with all affected individuals in the family and was not found in unaffected family members nor in the 100 unrelated controls. Bioinformatics analysis indicated that the 54th amino acid position was highly conserved and the mutation R54L caused an increase of local hydrophobicity around the substitution site. This study identified a novel disease-causing mutation c.161 G > T (p.R54L) in CRYAA in a Chinese family with autosomal dominant nuclear cataracts, this is the first report relating a G > T mutation in CRYAA leading to congenital nuclear cataract.

    The aim of the study was to characterize the underlying mutation in a large multiplex Chinese family with hereditary nuclear cataract. A 6-generation Chinese family having hereditary nuclear cataract was recruited and clinically verified. Blood DNA samples were obtained from 53 available family members. Linkage analyses were performed on the known candidate regions for hereditary cataract with 36 polymorphic microsatellite markers. To identify mutations related to cataract, a direct sequencing approach was applied to a candidate gene residing in our linkage locus. A linkage locus was identified with a maximum 2-point LOD score of 4.31 (recombination fraction = 0) at marker D1S498 and a maximum multipoint LOD score of 5.7 between markers D1S2344 and D1S498 on chromosome 1q21.1, where the candidate gene Cx50 is located. Direct sequencing of Cx50 showed a 139 G to A transition occurred in all affected family members. This transitional mutation resulted in a replacement of aspartic acid by asparagine at residue 47 (D47N) and led to a loss-of-function of the protein. The D47N mutation of Cx50 causes the hereditary nuclear cataract in this family in an autosomal dominant mode of inheritance with incomplete penetrance.

    This series of slides presents the organization of the Chinese nuclear industry and its perspectives for the 2 next decades. The presentation is divided into 5 parts. Part one: the energy sector in China. Due to the economic development of the country this sector is flourishing and reaches an average growth rate of 9% per year. More than fifty per cent of the power plants being built in the world, are located in China. The electricity production stems by far from fossil energies (>80%) but this part is expected to decrease to reach 70% in 2020. Part 2: the Chinese nuclear program. This program is dual: the massive deployment of chinese improved reactors of second generation (the construction of 6 CPR1000 reactors will be launched each year) and the import and assimilation of reactors of the third generation: 4 AP1000 and 2 EPR are being built. Part 3: the organization of the Chinese nuclear sector. The main actors are CNNC (China National Nuclear Corporation), CGNPC (China Guangdong Nuclear Power Corporation), CPI (China Power Investment Corporation), SNPTC (State Nuclear Power Technology Corporation). The main 5 Chinese suppliers are also presented. Part 4: The role of EDF. Today's EDF role is multiple: to be active in the Chinese nuclear program, to go beyond technical assistance to reach partnership, to invest in Chinese power plants, to promote cooperation between French and Chinese actors of the nuclear industry. A lot of joint ventures have been created. Part 5: the Taishan project. Taishan is a coastal site near Macao in the Guangdong province in which 2 EPR are being built, the first concrete was cast in october 2009, 52 months of construction are scheduled and the first unit will be commissioned in end 2013 while the second commissioning is planned for end 2014.

    The goal of this study was to characterize the disease-causing mutations in a Chinese family with congenital nuclear and posterior polar cataracts. Clinical data of patients in the family were recorded using slit-lamp photography and high definition video. Genomic DNA samples were extracted from the peripheral blood of the pedigree members and 100 healthy controls. Mutation screening was performed in the candidate genes by bi-directional sequencing of the amplified products. The congenital cataract phenotype of the pedigree was identified by slit-lamp examinations and observation during surgery as nuclear and posterior polar cataracts. Through the sequencing of the candidate genes, a heterozygous c. 418C>T change was detected in the coding region of the γD-crystallin gene (CRYGD). As a result of this change, a highly conserved arginine residue was replaced by a stop codon (p. R140X). This change was discovered among all of the affected individuals with cataracts, but not among the unaffected family members or the 100 ethnically matched controls. This study identified a novel congenital nuclear and posterior polar cataract phenotype caused by the recurrent mutation p. R140X in CRYGD.

    Aim: To assess the contribution of single nucleotide polymorphisms (SNP) and haplotypes in the peroxisome proliferator-activated receptor-γ co-activator-1(PPARGC1) and adiponectin genes to normal bone mineral density (BMD) variation in healthy Chinese women and men. Methods: We performed population-based (ANOVA) and family-based (quantitative trait locus transmission disequi-librium test) association studies of PPARGC1 and adiponectin genes. SNP in the 2 genes were genotyped. BMD was measured using dual-energy X-ray absorptiometry in the lumbar spine and hip in 401 nuclear families with a total of1260 subjects, including 458 premenopausal women, 20-40 years of age; 401 post-menopausal women (mothers), 43-74 years of age; and 401 men (fathers), 49-76years of age. Results: Significant within-family association was found between the Thr394Thr polymorphism in the PPGAGC1 gene and peak BMD in the femoral neck (P=0.026). Subsequent permutations were in agreement with this significant within-family association result (P=0.016), but Thr394Thr SNP only accounted for0.7% of the variation in femoral neck peak BMD. However, no significant within-family association was detected between each SNP in the adiponect in gene and peak BMD. Although no significant association was found between BMD and SNP in the PPARGC1 and adiponectin genes in both men and postmenopausal women, haplotype 2 (T-T) in the adiponect in gene was associated with lumbar spine BMD in postmenopausal women (P=0.019). Conclusion: Our findings sug-gest that Thr394Thr SNP in the PPARGC1 gene was associated with peak BMD in the femoral neck in Chinese women. Confirmation of our results is needed in other populations and with more functional markers within and flanking the PPARGC1 or adiponectin genes region.

    Congenital cataract (CC) is the leading cause of visual disability in children. To date, mutations in many genes have been linked to CC. In a four-generation Chinese family with congenital nuclear pulverulent and posterior polar cataracts, we detected a heterozygous c.5G>A transition in the second exon of GJA3, resulting in the substitution of a highly conserved glycine with aspartic acid (p.G2D) at the N-terminus of the connexin46 (Cx46) protein. Wild type (wt) and mutant Cx46 plasmids were transfected into HeLa cells to examine the molecular basis of cataract formation. Unlike wt Cx46, Cx46G2D mutant formed gap junction plaques inefficiently, changed hemichannel permeability, and caused apoptosis. These results suggest that the glycine residue at the second position of the N-terminus is important for gap junction plaque formation and hemichannel function. © 2011 Wiley Periodicals, Inc.

    Full Text Available Abstract Background The Wnt/beta-catenin signaling pathway plays an important role in skeletal development. Polymorphisms of frizzled-related protein (FRZB, an antagonist of this pathway, may generate variations in bone mineral density (BMD. In this study, we analyzed the association between FRZB genotypes and peak BMD variation in the spines and hips of two relatively large samples of Chinese female-offspring and male-offspring nuclear families. Methods We recruited 1,260 subjects from 401 female-offspring nuclear families and 1,296 subjects from 427 male-offspring nuclear families and genotyped four tagging single nucleotide polymorphisms (tagSNPs (rs6433993, rs409238, rs288324, and rs4666865 spanning the entire FRZB gene. The SNPs rs288326 and rs7775, which are associated with hip osteoarthritis, were not selected in this study because of their low minor allele frequencies (MAFs in Chinese people. The quantitative transmission disequilibrium test (QTDT was used to analyze the association between each SNP and haplotype with peak BMD in female- and male-offspring nuclear families. Results In the female-offspring nuclear families, we found no evidence of an association between either single SNPs or haplotypes and peak BMD in the spine or hip. In the male-offspring nuclear families, no within-family association was observed for either SNPs or haplotypes, although a significant total association was found between rs4666865 and spine BMD (P = 0.0299. Conclusion Our results suggest that natural variation in FRZB is not a major contributor to the observed variability in peak BMD in either Chinese females or males. Because ethnic differences in the FRZB genotypes may exist, other studies in different population are required to confirm such results.

    The purpose of this study was to identify the disease-causing mutation and the molecular phenotype that are responsible for the presence of an autosomal dominant congenital nuclear cataract disease in a Chinese family. The family history and clinical data were recorded. The patients were given a physical examination and their blood samples were collected for DNA extraction. Direct sequencing was used to detect the mutation. Transcription analysis of the mutant crystallin, beta A1 (CRYBA1/A3) gene was performed to verify whether the defective mutation had influenced the splice of the mature mRNA. The phenotype of the congenital cataract in the family was identified as a nuclear cataract type, by using slit-lamp photography. Direct sequencing revealed a novel mutation IVS3+2 T→G in CRYBA1/A3. This mutation co-segregated with all affected individuals in the family, but was not found in unaffected family members nor in the 100 unrelated controls. Transcription analysis of the mutant CRYBA1/A3 gene indicated that this mutation had influenced the splice of the mature mRNA. Our study identified a novel splice site mutation in CRYBA1/A3. This mutation was responsible for aberrant splicing of the mature mRNA and had caused the congenital nuclear cataracts in the family. This is the first report relating an IVS3+2 T→G mutation of CRYBA1/A3 to congenital cataracts.

    Chinese President Xi Jinping addresses China's new concept of nuclear security with four 'equal emphasis' at the third Nuclear Security Summit, and makes four commitments to strengthen nuclear security in the future. To convert President Xi's political commitments into practical, sustainable reality, China should take further steps to install a complete, reliable, and effective security system to ensure that all its nuclear materials and nuclear facilities are effectively protected against the full spectrum of plausible terrorist and criminal threats. This paper suggests the following measures be taken to improve China's existing nuclear security system, including updating and clarifying the requirements for a national level DBT; updating and enforcing existing regulations; further promoting nuclear security culture; balancing the costs of nuclear security, and further strengthening international cooperation on nuclear security.

    Knowledge of acculturative processes and their impact on immigrant families remains quite limited. Acculturative family distancing (AFD) is the distancing that occurs between immigrant parents and their children and is caused by breakdowns in communication and cultural value differences. It is a more proximal and problem-focused formulation of the acculturation gap and is hypothesized to increase depression via family conflict. Data were collected from 105 Chinese American high school students and their mothers. Rasch modeling was used to refine the AFD measure, and structural equation modeling was used to determine the effects of AFD on youth and maternal depression. Findings indicate that greater AFD was associated with higher depressive symptoms and risk for clinical depression. Family conflict partially mediated this relation for youths, whereas for mothers, AFD directly increased risk for depression. Greater mother-child heritage enculturation discrepancies were associated with greater mother and child AFD. Mainstream acculturation discrepancies and language gaps between mothers and youths were not significantly associated with any of the primary outcome variables. Results highlight the need for better understanding of how AFD and other acculturation-gap phenomena affect immigrant mental health. They also underscore the need for prevention and intervention programs that target communication difficulties and intergenerational cultural value differences.

    2015-01-01

    Full Text Available Background: Mutations of transthyretin (TTR cause the most common type of autosomal-dominant hereditary systemic amyloidosis, which occurs worldwide. To date, more and more mutations in the TTR gene have been reported. Some variations in the clinical presentation are often observed in patients with the same mutation or the patients in the same family. The purpose of this study was to find out the clinicopathologic and genetic features of Chinese patients with hereditary TTR amyloidosis. Methods: Clinical and necessary examination materials were collected from nine patients of eight families with hereditary TTR amyloidosis at Peking University First Hospital from January 2007 to November 2014. Sural nerve biopsies were taken for eight patients and skin biopsies were taken in the calf/upper arm for two patients, for light and electron microscopy examination. The TTR genes from the nine patients were analyzed. Results: The onset age varied from 23 to 68 years. The main manifestations were paresthesia, proximal and/or distal weakness, autonomic dysfunction, cardiomyopathy, vitreous opacity, hearing loss, and glossohypertrophia. Nerve biopsy demonstrated severe loss of myelinated fibers in seven cases and amyloid deposits in three. One patient had skin amyloid deposits which were revealed from electron microscopic examination. Genetic analysis showed six kinds of mutations of TTR gene, including Val30Met, Phe33Leu, Ala36Pro, Val30Ala, Phe33Val, and Glu42Gly in exon 2. Conclusions: Since the pathological examinations of sural nerve were negative for amyloid deposition in most patients, the screening for TTR mutations should be performed in all the adult patients, who are clinically suspected with hereditary TTR amyloidosis.

  8. The modern Chinese family in light of economic and legal history.

    Huang, Philip C C

    2011-01-01

    Most social science theory and the currently powerful Chinese ideology of modernizationism assume that, with modern development, family-based peasant farm production will disappear, to be replaced by individuated industrial workers and the three-generation family by the nuclear family. The actual record of China’s economic history, however, shows the powerful persistence of the small family farm, as well as of the three-generation family down to this day, even as China’s GDP becomes the second largest in the world. China’s legal system, similarly, encompasses a vast informal sphere, in which familial principles operate more than individualist ones. And, in between the informal-familial and the formal-individualist, there is an enormous intermediate sphere in which the two tendencies are engaged in a continual tug of war. The economic behavior of the Chinese family unit reveals great contrasts with what is assumed by conventional economics. It has a different attitude toward labor from that of both the individual worker and the capitalist firm. It also has a different structural composition, and a different attitude toward investment, children’s education, and marriage. Proper attention to how Chinese modernity differs socially, economically, and legally from the modern West points to the need for a different kind of social science; it also lends social–economic substance to claims for a modern Chinese culture different from the modern West’s.

    Full Text Available Family tree is an efficient data structure to store the kinship information in a family. There are basically two kinds of trees: Western Family Tree (WFT and Oriental Family Tree such as Chinese Family Tree (CFT. To get an insight of their efficiency in the context of family kinship presentation and information extraction, in this paper we develop WFT and CFT presentation models and search algorithms, comparing their search performance and inherent mechanism. The study reveals that the computational cost is higher in CFT model, but it provides a greater gain in information retrieval and produces more details of the kinship between individuals in the family.

    The concepts of quality of life and family quality of life (FQOL) are increasingly being studied in the field of intellectual disabilities (ID) in China as important frameworks for: (1) assessing families' need for supports and services; (2) guiding organisational and service delivery system changes; and (3) evaluating quality family outcomes. The present study focused on exploring the perceptions of Chinese families who have a child with an ID regarding FQOL as well as examining the factor structure of FQOL concept from Chinese families. The Chinese version of the Family Quality of Life Scale was used to survey Chinese families living in the urban and suburban areas of Beijing who have a child with ID. A total of 442 families participated in this study. Confirmatory factor analysis was used to test the factor structure of FQOL. Multivariate analysis was also used to examine group differences among families in terms of family demographic variables. A five-factor structure of the FQOL construct was found in the Chinese sample, suggesting a similar factor structure found from US families in the literature. Different living conditions (e.g. housing and transportation) tended to affect significantly families' satisfaction ratings of their FQOL. It is also found that family income and severity of disability of the child are predictors of families' satisfaction ratings of FQOL. The preliminary findings of this study suggest a cross-cultural factor structure comparability of FQOL between samples in the USA and China. Results call for further examination of the family-centred service and support as a mediator on the interactive relationship between family characteristics, family needs and FQOL outcomes. © 2011 The Authors.

    The purpose of this study was to explore the bereavement experiences of parents who had experienced the death of a child in Chinese families. In-depth interviews were conducted with 10 bereaved parents in Macau, China. Narrative accounts of Chinese parents' experience in the loss of a child were explored to understand how their connection to the deceased child and their worldview were influenced by cultural beliefs and values. Study themes related to parental connections with the deceased child included the use of object linking, memorializing acts, and avoidance of traditional funeral processes, with clear patterns of Chinese cultural influence. Additionally, themes related to impacts on parental worldview included use of the concept of fate as a rationale for child loss and influences on religious orientation. The influence of cultural beliefs and background on Chinese parents as they deal with the issue of a child's death was apparent. Further research is needed and will benefit our understanding of parental bereavement in Chinese families.

    It is a familiar sight in many Chinese cities to witness a large team escorting a baby pram in public:mother,grandmothers,ayi (nanny),another ayi maybe,grandfathers quiet possible,and finally father if you are lucky.Yes,after China's implementation of “One Child Only” policy in the late of 1970s,it's the time for the baby boom generation to create another round of baby boom.The babies get so much attention and love from their 4grandparents,2 parents,and more ayis.Whilst it once was very common for grandparents to take care of the baby and toddler at home when both parents are at work,now the trend is changing slightly.

    We report here the clinical, genetic, and molecular characterization of three Chinese families (WZ4, WZ5, and WZ6) with Leber's hereditary optic neuropathy (LHON). Clinical and genetic evaluations revealed the variable severity and age-of-onset in visual impairment in these families. Penetrances of visual impairment in these Chinese families were 33.3%, 35.7%, and 35.5%, respectively, with an average 34.8%. Furthermore, the average age-at-onset in those Chinese families was 17, 20, and 18 years. In addition, the ratios between affected male and female matrilineal relatives in these Chinese families were 3:0, 1:1, and 1.2:1, respectively. Sequence analysis of the complete mitochondrial genomes in these pedigrees showed the distinct sets of mtDNA polymorphism, in addition to the identical G11778A mutation associated with LHON in many families. The fact that mtDNA of those pedigrees belonged to different haplogroups F1, D4, and M10 suggested that the G11778A mutation occurred sporadically and multiplied through evolution of the mtDNA in China. However, there was the absence of functionally significant mutations in tRNA and rRNAs or secondary LHON mutations in these Chinese families. The I187T mutation in the ND1, the S99A mutation in the A6, the V254I in CO3, and I58V in ND6 mutation, showing high evolutional conservation, may contribute to the phenotypic expression of the G11778A mutation in the WZ6 pedigree. By contrast, none of mtDNA variants are evolutionarily conserved and implicated to have significantly functional consequence in WZ4 and WZ5 pedigrees. Apparently, these variants do not have a potential modifying role in the development of visual impairment associated with G11778A mutation in those two families. Thus, nuclear modifier gene(s) or environmental factor(s) seem to account for the penetrance and expressivity of LHON in these three Chinese families carrying the G11778A mutation

    Cranial neuropathy is usually idiopathic and familial cases are uncommon. We describe a family with 5 members with cranial neuropathy over 3 generations. All affected patients were women, indicating an X-linked dominant or an autosomal dominant mode of inheritance. Our cases and a review of the literature suggest that familial idiopathic cranial neuropathy is a rare condition which may be related to autosomal dominant vascular disorders (e.g. vascular tortuosity, sclerosis, elongation or extension), small posterior cranial fossas, anatomical variations of the posterior circulation, hypersensitivity of cranial nerves and other abnormalities. Moreover, microvascular decompression is the treatment of choice because vascular compression is the main factor in the pathogenesis. To the best of our knowledge, this is the first report of familial cranial neuropathy in China.

    Being convinced that nuclear energy will play an important role in meeting its huge future energy demands, China considers that the development of a very strong national nuclear industry capable of covering all aspects of a major national power program is of paramount importance.In this context, China has invited its foreign partners to propose contributions to the studies for this development, in view of establishing a suitable cooperation program with the entire Chinese nuclear power industry, including design institutes, equipment manufacturers, construction companies and plant operators.One of the main objectives defined by the Chinese authorities for the further development of their nuclear industry with some international cooperation is the achievement of a very high level of self-reliance by Chinese industry in all of the following areas: project management, design and engineering, construction, equipment design and manufacturing,operation and maintenance. The major key to reaching this target of overall and long term self reliance lies in the implementation of thorough design know how transfer towards all partners of the Chinese nuclear industry, who shall acquire the necessary capabilities so as to completely master nuclear engineering. While this policy might entail fairly high front end investments by the technology receivers, in terms of industrial infrastructure nad engineering capabilities it is expected to pay off over the long term with the development of a substantial nuclear power plant construction program.(DM)

The participants were 2001 Chinese college freshmen with the age from 16 to 20 years. Data were collected by using the family assessment device (FAD), the Rosenberg Self-esteem Scale, and self-report of family information. Comparison analysis indicated that the students from one child families, harmonious families, from families with higher income, or raised by their parents without the experience of grandparenting are more likely to show high self-esteem than their counterparts. Moreover, a multiple regression showed that dimensions of FAD such as role, communication, behavioral control, and problem solving predicted level of self-esteem of the college students, ranging from 13.2 to 17.9% variance. The results of this study showed that the self-esteem of the college freshmen is highly correlated with their family's performance. Therefore, the program focusing on improving family functioning is needed, in order to enhance the self-esteem of the young people and hence contribute to promoting the mental health of them.

    China has been carrying out active international cooperation aiming to be a country where is to be an economical super power and an advanced country in nuclear power technology by the year early 2000, and China also has begun to be recognized as the largest potential market for the construction of nuclear power plants(NPPs) expecting to construct more than thirty nuclear power units by the year 2020. China has advanced technology in the basic nuclear science including liquid metal breeder reactor technology, nuclear material, medium and small size power plants, and isotope production technology, and also China has complete nuclear fuel cycle technology. However, China still has low NPP technology. Therefore, it is expected that China may have complementary cooperative relationship with China, it is expected that Korea may have an access to the advanced Chinese nuclear science technology, and may have a good opportunity to explore the Chinese market actively exporting excellent Korean NPP technology, and further may have a good position to the neighboring Asian countries' NPP markets. From this perspective, general Chinese social status, major nuclear R and D activity status, and correct NPP and technology status have been analyzed in this report, and this report is expected to be a useful resource for cooperating with China in future. 10 tabs., 6 figs., 16 refs.

    This study aimed to develop a family-centered care survey for Chinese adult intensive care units and to establish the survey's psychometric properties. Family-centered care (FCC) is widely recognized as an ideal model of care. Few studies have explored FCC perceptions among family members of adult critical care patients in Asian countries, and no Chinese FCC measurement has been developed. An English version of the 3-factor family-centered care survey for adult intensive care units (FCCS-AICU) was translated into Chinese using a modified back translation procedure. Based on the literature review, two additional concepts, information and empowerment, were added to the Chinese FCCS-AICU. The psychometric properties of the Chinese FCCS-AICU were determined with 249 family members from a medical center in Taiwan and were tested for construct and convergent validity, and internal consistency. Both the monolingual and bilingual equivalence tests of the English and Chinese versions of the 3-factor FCCS-AICU were supported. Exploratory factor analysis supported the 5-factor structure of the Chinese FCCS-AICU with a total explained variance of 58.34%. The Chinese FCCS-AICU was correlated with the Chinese Critical Care Family Needs Inventory. Internal consistency, determined by Cronbach's α, for the overall scale was .94. The Chinese FCCS-AICU is a valid and reliable tool for measuring perceptions of FCC by family members of adult intensive care patients within Chinese-speaking communities.

    Full Text Available Abstract Introduction Tumoral calcinosis is a rare and benign condition characterized by massive subcutaneous soft tissue deposits of calcium phosphate predominantly around large joints. Case presentation Familial tumoral calcinosis was present in two members of a Han Chinese family, namely, the son and daughter. The 14-year-old son had the first operation on his right sole of the foot at the age of six, and then experienced subsequent surgeries at a lesion in his right sole of the foot and left hip, respectively. The 16-year-old daughter underwent her first operation at the age of six in her left gluteal region, and subsequent surgeries were performed due to recurrence at the same lesion. Pathologic diagnoses of surgical specimens in both of the patients were reported as tumoral calcinosis. The laboratory results showed hyperphosphatemia with normal levels of serum calcium and alkaline phosphatase. Only surgical treatment was performed in both patients with satisfactory prognosis. Conclusion This is the first report of Chinese familial tumoral calcinosis. The etiopathogenisis and treatment are discussed.

    Full Text Available Objective To study the genotype of the members of a Chinese family with spinocerebellar ataxia (SCA. Methods The peripheral blood samples of 6 patients and 40 asymptomatic people belonged to the family were collected. Referring to the clinical manifestations of the proband and second-generation sequencing results, the CAG trinucleotide repeats of the pathogenic gene ATXN2 were amplified by polymerase chain reaction (PCR. The repeated times of the trinucleotide in normally and abnormally amplified alleles were defined by agarose gel electrophoresis and PCR products sequencing. Results Autosomal dominant heredity was the cause of the SCA in this family. Six out of 46 in the fourth-generation were SCA2 patients, 7 were the carriers of pathogenic allele. The repeated times of CAG trinucleotide were within the normal range in one of the two alleles of ATXN2, but they were in abnormal range in the another one. The repeated times of CAG trinucleotide were 40-46 in abnormal alleles of patients. Conclusion Autosomal dominant heredity SCA2 has been diagnosed in this family caused by the dynamic nutation of CAG trinucleotide repeats, and 7 pathogenic allele carriers in this family were confirmed by genetic diagnosis.

    The electricity production is steadily growing in China and the intense use of coal has led to various problems such as -) important contamination of urban areas, -) safety concerns in coal mines, and -) coal transport as the production regions are not the consumption regions. In 2004, Chinese authorities decided to accelerate the recourse to nuclear power. The main measures that were adopted followed: -) the development of the CPR1000 that is a Chinese improved version of the Areva 900 MW PWR; -) the development of a Chinese third generation reactor based on foreign design: 4 AP1000 and 2 EPR have been ordered; -) the adoption of a closed cycle for the fuel; -) the participation to international collaborations like GIF (Generation 4 International Forum) and to ITER. Today the number of operating power reactors in China is 11 and 26 have been ordered. The objective is to reach a share of 20% for nuclear power in the electricity production which means 250 GW installed by 2050. It appears that the nuclear renaissance has begun in Asia and real opportunities for the European nuclear industry are there. (A.C.)

    To explore beliefs about diet and traditional Chinese medicine related to the breast cancer experience of Hong Kong Chinese women and their families. Interpretive phenomenology. Hong Kong, China. A purposive sample of 20 Hong Kong Chinese women diagnosed with breast cancer at various stages of the illness trajectory and at least one other family member. A semistructured, three-hour interview was translated, transcribed, and back-translated. Many women and their family members believed that diet was responsible for their cancer and recurrence. They integrated their cultural beliefs about diet and traditional Chinese medicine to manage illness symptoms and prevent recurrence. Families were anxious and confused about conflicting messages from various sources about dietary practices to promote their health and prevent recurrence. Food and diet alternatives should be discussed with the understanding that beliefs about diet and traditional Chinese medicine are embedded in culture and that many Chinese women and their families seek a combination of Eastern Chinese medicine and Western medicine strategies to manage the illness trajectory. Many Chinese families have different beliefs about food and diet and the role that food plays in managing the cancer experience. Often, Chinese people will not seek clarification if they do not understand information. If information does not fit with their predominant belief systems, families may not implement it, nor will they discuss a situation if they think the conversation will result in a relationship of conflict with healthcare providers.

    China still extended their experiences to both domestic and overseas so far. Chinese State Council approved its 'Medium and Long-term Nuclear Power Development Plan' in November 2007, indicating further definition for nuclear energy as indispensable energy option and future self-reliance development of nuclear industry. China intends to become self-sufficient not only in NPPs capacity, but also in the fuel production for all those plants. There are currently 17 NPPs in operation, and 28 NPPs under construction. However, domestic uranium mining supplying is currently less than a quarter of nuclear fuel demands. This paper investigated and summarized the updated status of NPP industry in China and Nuclear Fuel Cycle(NFC) policy. There still remain a number of technical innovation and comprehensive challenges for this nuclear developing country in the long-term, but its large ambitions and dramatic improvements toward future should not be ignored. As shown in this paper, the most suitable approach for China to achieve both environmentally-friendly power supplying and increasing energy demands meeting simultaneously must be considered. Nuclear energy now was recognized as the most potential and optimal way of energy supply system. In addition, to accommodate such a high-speed NPP construction in China, it should also focus on when and how spent nuclear fuel should be reprocessed. Finally, the nuclear back-end fuel cycle policy should be established, taking into accounts of all costs, uranium resource security, spent fuel management, proliferation resistance and environmental impact.

    We report here the clinical, genetic, and molecular characterization of five Chinese families with Leber's hereditary optic neuropathy (LHON). Clinical and genetic evaluations revealed the variable severity and age-of-onset in visual impairment in these families. Strikingly, there were extremely low penetrances of visual impairment in these Chinese families. Sequence analysis of the complete mitochondrial genomes in these pedigrees showed the distinct sets of mtDNA polymorphism, in addition to the identical ND4 G11696A mutation associated with LHON. Indeed, this mutation is present in homoplasmy only in the maternal lineage of those pedigrees but not other members of these families. In fact, the occurrence of the G11696A mutation in these several genetically unrelated subjects affected by visual impairment strongly indicates that this mutation is involved in the pathogenesis of visual impairment. Furthermore, the N405D in the ND5 and G5820A in the tRNA Cys , showing high evolutional conservation, may contribute to the phenotypic expression of G11696A mutation in the WZ10 pedigree. However, there was the absence of functionally significant mtDNA mutations in other four Chinese pedigrees carrying the G11696A mutation. Therefore, nuclear modifier gene(s) or environmental factor(s) may play a role in the phenotypic expression of the LHON-associated G11696A mutation in these Chinese pedigrees

    The present study aimed to explore the prevalence and frequency of child psychological maltreatment and its correlated factors in Chinese families. A cross-sectional investigation was conducted among 1,002 parents of primary school students in Yuncheng City, China. Data were collected using the self-report questionnaire anonymously. Results showed that 696 (69.5%) surveyed parents had different extents of psychological maltreatment toward their children in the past 3 months. The high prevalence of parental psychology maltreatment was significantly associated with high scores on parental over-reactivity and low scores on recognition of child psychology maltreatment. These findings indicate that it is urgent to develop cultural interventions to raise parents' awareness of preventing child psychological maltreatment and to help parents use nonviolent child rearing in China.

    We report here the characterization of a five-generation large Chinese family with Leber's hereditary optic neuropathy (LHON). Very strikingly, six affected individuals of 38 matrilineal relatives (17 females/21 males) are exclusively males in this Chinese family. These matrilineal relatives in this family exhibited late-onset/progressive visual impairment with a wide range of severity, ranging from blindness to normal vision. The age of onset in visual impairment varies from 17 to 30 years. Sequence analysis of the complete mitochondrial genome in this pedigree revealed the presence of the G11778A mutation in ND4 gene and 29 other variants. This mitochondrial genome belongs to the Southern Chinese haplogroup B5b. We showed that the G11778A mutation is present at near homoplasmy in matrilineal relatives of this Chinese family but not in 164 Chinese controls. Incomplete penetrance of LHON in this family indicates the involvement of modulatory factors in the phenotypic expression of visual dysfunction associated with the G11778A mutation. However, none of other mtDNA variants are evolutionarily conserved and implicated to have significantly functional consequence. Thus, nuclear modifier gene(s) or environmental factor(s) seem to account for the penetrance and phenotypic variability of LHON in this Chinese family carrying the G11778A mutation

Eight of the family members were affected in this pedigree. The affected family members exhibited early-onset and progressive visual impairment, resulting in mild to profound loss of visual acuity. The average age-at-onset was 15.9 years. A new heterozygous mutation c.C1198G was identified by sequence analysis of the 12th exon of the OPA1 gene. This mutation resulted in a proline to alanine substitution at codon 400, which was located in an evolutionarily conserved region. This missense mutation in the GTPase domain was supposed to result in a loss of function for the encoded protein and act through a dominant negative effect. No other mutations associated with optic atrophy were found in our present study. The c.C1198G heterozygous mutation in the OPA1 gene may be a novel key pathogenic mutation in this pedigree with ADOA. Furthermore, additional nuclear modifier genes, environmental factors, and psychological factors may also contribute to the phenotypic variability of ADOA in this pedigree.

    Juang, Linda P; Alvarez, Alvin A

    2010-12-01

    We examined racial/ethnic discrimination experiences of Chinese American adolescents to determine how discrimination is linked to poor adjustment (i.e., loneliness, anxiety, and somatization) and how the context of the family can buffer or exacerbate these links. We collected survey data from 181 Chinese American adolescents and their parents in Northern California. We conducted hierarchical regression analyses to examine main effects and 2-way interactions of perceived discrimination with family conflict and family cohesion. Discrimination was related to poorer adjustment in terms of loneliness, anxiety, and somatization, but family conflict and cohesion modified these relations. Greater family conflict exacerbated the negative effects of discrimination, and greater family cohesion buffered the negative effects of discrimination. Our findings highlight the importance of identifying family-level moderators to help adolescents and their families handle experiences of discrimination.

    Osteoporosis is a major public health concern and its prevalence can be predicted based on forearm bone mineral density (BMD). This study is to investigate the familial aggregation of forearm BMD in a population-based, cross-sectional study in Anhui, China. Information on sociodemographic and environmental variables was obtained from 1,636 subjects from 409 nuclear families (including mother, father, and their first two children) by a standardized questionnaire. The forearm BMD was measured by peripheral dual-energy X-ray absorptiometry (pDXA). Using generalized additive models with a sequential adjustment for covariates, it was clearly indicated that the forearm BMD of the mother, the father, and the first sibling each had a significant and independent relation to the forearm BMD of the second sibling. Furthermore, using multiple logistic regression, the second sibling had an odds ratio (OR) of 5.3 (95%CI: 2.0-14.5) of having an extremely low (bottom 10th percentile) proximal forearm BMD and an OR of 4.3 (95%CI: 1.6-12.0) of having an extremely low distal forearm BMD when the parental mean forearm BMD was low and the first sibling's forearm BMD was low. Our findings showing strong familial aggregation of both proximal and distal forearm BMD values suggest that genetic factors play a significant role in determining both traits

  18. The Chinese nuclear arsenal and its second-strike capability

    2013-03-01

    It is well known that China possesses a second- strike capability, but a great deal of uncertainty persists on the subject. Over the last few years, without officially adjusting its doctrine, China has nonetheless defined its objectives. In April 2010, the People's Liberation Army Daily indicated that China needed such a capability and contended that ballistic missile submarines (SSBNs) would constitute the safest means of delivery. In the same year, the IISS estimated that the People's Liberation Army was in possession of 90 ICBMs (66 ground-based missiles and 24 SLBMs) and 400 IRBM mainly aimed at Taiwan and Japan. The Pentagon's 2012 report proposed 50-75 ICBMs and 80 -120 IRBM and MRBM. While it is established that the People's Liberation Army is developing Jin class submarines (type-094, of which there are currently two in service, which will soon rise to five) and is developing solid-propellant missiles, which could be activated more quickly, not a great deal is known about the progress of these two projects. The JL-2 (7400 km), which is mounted on SSBNs, is still being tested. In parallel, the traditional principle to which China adheres - no first use of nuclear weapons - seems to have been slightly dented. Thus, in January 2011, the Japanese press agency Kyodo (relayed by Stratfor) reported that the People's Liberation Army had lowered the threshold for use of its strategic weapons: it could henceforth envisage a preventive nuclear strike against a nuclear power that had by conventional means destroyed key strategic targets on its territory, such as a nuclear power station, a dam, or a large city, having provided prior warning to the aggressor. But what most worries the U.S. and its Asian allies, particularly the Japanese, is the quasi-total opacity of the Chinese military nuclear programme. While in April 2010, the United States and Russia signed a treaty limiting their number of strategic weapons to 1550 by 2018, China considers that its programme cannot

    2009-10-01

    Although Asians demonstrate elevated levels of type 2 diabetes, little attention has been directed to their unique cultural beliefs and practices regarding diabetes. We describe cultural and family challenges to illness management in foreign-born Chinese American patients with type 2 diabetes and their spouses. This was an interpretive comparative interview study with 20 foreign-born Chinese American couples (n = 40) living with type 2 diabetes. Multiple (six to seven) semistructured interviews with each couple in individual, group, and couple settings elicited beliefs about diabetes and narratives of care within the family and community. Interpretive narrative and thematic analysis were completed. A separate respondent group of 19 patients and spouses who met the inclusion criteria reviewed and confirmed the themes developed from the initial couples. Cultural and family challenges to diabetes management within foreign-born Chinese American families included how 1) diabetes symptoms challenged family harmony, 2) dietary prescriptions challenged food beliefs and practices, and 3) disease management requirements challenged established family role responsibilities. Culturally nuanced care with immigrant Chinese Americans requires attentiveness to the social context of disease management. Patients' and families' disease management decisions are seldom made independent of their concerns for family well-being, family face, and the reciprocal responsibilities required by varied family roles. Framing disease recommendations to include cultural concerns for balance and significant food rituals are warranted.

    2011-09-01

    Full Text Available This paper compares and contrasts the ethnographic practices of two non-native researchers - a Singaporean researcher studying families in mainland China and a Swedish researcher studying Chinese families in Singapore. A novel conceptual frame of ‘radius of observation positions’ has been proposed to explicate the extent of intrusion and intimacy to which researchers may venture in the private family domain. The opportunities and challenges of two positions of observation within this radius are discussed. The choice of position is largely influenced by the interacting forces of the contextual and cultural factors as well as the personhood of the researcher. The authors call for special attention to cultural sensitivity in conducting Chinese family research. Families are embedded in culture, and the possibility of accessing family spaces hinges on one's awareness of the intricacies of family cultures and realistic assessment of one's strengths and limitations in handling complex family dynamics.

    Objective: Nance-Horan syndrome (NHS) is a rare X-linked disorder characterized by congenital nuclear cataracts, dental anomalies, and craniofacial dysmorphisms. Mental retardation was present in about 30% of the reported cases. The purpose of this study was to investigate the genetic and clinical features of NHS in a Chinese family. Methods: Whole exome sequencing analysis was performed on DNA from an affected male to scan for candidate mutations on the X-chromosome. Sanger sequencing was used to verify these candidate mutations in the whole family. Clinical and ophthalmological examinations were performed on all members of the family. Results: A combination of exome sequencing and Sanger sequencing revealed a nonsense mutation c.322G>T (E108X) in exon 1 of NHS gene, co-segregating with the disease in the family. The nonsense mutation led to the conversion of glutamic acid to a stop codon (E108X), resulting in truncation of the NHS protein. Multiple sequence alignments showed that codon 108, where the mutation (c.322G>T) occurred, was located within a phylogenetically conserved region. The clinical features in all affected males and female carriers are described in detail. Conclusions: We report a nonsense mutation c.322G>T (E108X) in a Chinese family with NHS. Our findings broaden the spectrum of NHS mutations and provide molecular insight into future NHS clinical genetic diagnosis. PMID:25091991

    The study provided validity evidence for a fourfold taxonomy of work-family balance that comprises direction of influence (work to family vs. family to work) and types of effect (work-family conflict vs. work-family facilitation). Data were collected from 189 employed parents in China. The results obtained from a confirmatory factor analysis supported the factorial validity of the fourfold taxonomy of work-family balance with a Chinese sample. Child care responsibilities, working hours, monthly salary, and organizational family-friendly policy were positively related to the conflict component of work-family balance; whereas new parental experience, spouse support, family-friendly supervisors and coworkers had significant positive effects on the facilitation component of work-family balance. In comparison with the inconsistent effects of work-family conflict, work to family facilitation had consistent positive effects on work and life attitudes. The implications of findings in relation to China and other countries are discussed in the paper.

    As the radioactive debris cloud from a Chinese nuclear test on September 26, 1976 began drifting eastward, the Laboratory's computational facilities were pressed into service to predict the possible environmental effects. ERDA asked us to calculate cloud trajectories and to estimate the fallout dose. The FAA asked us to provide dose estimates both for commercial aircraft flights within the U.S. and for transatlantic flights of the Concorde SST. Our dose estimates, calculated with 2BPUFF, a large-cloud diffusion code, proved to be accurate predictions, correlating well with later observations. At FAA and ERDA request, we also worked with EG and G to measure cabin dose rates in some transatlantic SST and subsonic flights while the debris cloud moved out over the Atlantic Ocean

    The main interest of this research was to add to the body of knowledge about the possible psychological impact of the nuclear threat on the family unit. Data were utilized from the Family Interaction, Stress and Nuclear War study conducted by Jules Riskin, M.D. and Victoria Dickerson, Ph.D. at the Mental Research Institute in Palo Alto, California. The sample consisted of ten families who were recruited for this study. In order to examine family-interaction variables and the impact of the threat of nuclear war, a standardized semi-structured family interview was conducted. Topics ranged from ordinary activities to external, non-nuclear stresses such as landslides or hurricanes, to the topic of nuclear war. A distinction is drawn between a family's level of nuclear concern while they discuss nuclear issues and a family's level of nuclear concern when viewed in the context of their overall pattern of family communication. In terms of family coping, family nuclear concern was found to be significantly related to two family-coping strategies. Families who utilized the coping strategies of seeking spiritual support and mobilizing the family to acquire and accept help were significantly less concerned about the threat of nuclear war

    2015-12-29

    The goal of this project was to explore family communication dynamics and their implications for smoking cessation. We conducted 39 in-depth dyadic and individual qualitative interviews with 13 immigrant smoker-family member pairs of Vietnamese (n = 9 dyads, 18 individuals) and Chinese (n = 4 dyads, 8 individuals) descent, including seven current and six former smokers and 13 family members. All 13 dyadic and 26 individual interviews were analyzed using a collaborative crystallization process as well as grounded theory methods. We identified three interrelated pathways by which tobacco use in immigrant Vietnamese and Chinese families impacts family processes and communication dynamics. Using a two-dimensional model, we illustrate how the shared consequences of these pathways can contribute to a dynamic of avoidance and noncommunication, resulting in individual family members "suffering in silence" and ultimately smoking being reinforced. We discuss the implications of these findings for development of smoking cessation interventions. © The Author(s) 2015.

    This qualitative study explored themes that described families taking care of elderly relatives with dementia in Chinese society. Ten families were invited for two in-depth family interviews involving spousal caregivers, child caregivers, and care recipients. Five themes resulted: positive affection as coping strategies, power and control in the caregiving relationship, adult children's involvement in caregiving, sibling rivalry, and intergenerational conflicts. The ways these themes functioned and helped in dementia care, the research implications, and limitations are discussed.

  2. Impacts of Geoengineering and Nuclear War on Chinese Agriculture

    2011-12-01

    Climate is one of the most important factors determining crop yields and world food supplies. To be well prepared for possible futures, it is necessary to study yield changes of major crops under different climate scenarios. Here we consider two situations: stratospheric sulfate geoengineering and nuclear war. Although we certainly do not advocate either scenario, we cannot exclude the possibilities: if global warming is getting worse, we might have to deliberately manipulate global temperature; if nuclear weapons still exist, we might face a nuclear war catastrophe. Since in both scenarios there would be reductions of temperature, precipitation, and insolation, which are three controlling factors on crop growth, it is important to study food supply changes under the two cases. We conducted our simulations for China, because it has the highest population and crop production in the world and it is under the strong influence of the summer monsoon, which would be altered in geoengineering and nuclear war scenarios. To examine the effects of climate changes induced by geoengineering and nuclear war on Chinese agriculture, we use the DSSAT crop model. We first evaluate the model by forcing it with daily weather data and management practices for the period 1978-2008 for all the provinces in China, and compare the results to observations of the yields of major crops in China (middle season rice, winter wheat, and maize). Then we perturbed observed weather data using climate anomalies for geoengineering and nuclear war simulations using NASA GISS ModelE. For stratospheric geoengineering, we consider the injection of 5 Tg SO2 per year into the tropical lower stratosphere. For the nuclear war scenario, we consider the effects of 5 Tg of soot that could be injected into the upper troposphere by a war between India and Pakistan using only 100 Hiroshima-size atomic bombs dropped on cities. We perturbed each year of the 31-year climate record with anomalies from each year of

    2011-08-01

    Full Text Available Being embedded in the interdisciplinary area of media and culture studies, this articlel explores the family melodrama in transnational Chinese cinema drawing upon theoretical discussions with regard to the historical emergence of melodrama in correspondence to, as Th. Elsaesser says, “periods of intense social and ideological crisis”. While serving as a reflection on the tension between tradition and modernity displayed in the domestic domain, Ang Lee’s Chinese-characterized family melodrama also illustrates the differences between Chinese and Hollywood family melodrama. Linked to the ongoing debate about “melodrama as a cross-cultural form”, in the process of analyzing the film text, our perceptions of generic dislocation or displacement, transcultural entanglements and globalization in light of contemporary cultural practices will be furthermore complicated.

    Family allocentrism is a domain-specific collectivistic attribute referring to the family. This research tested the one-factor structure of the Family Allocentrism Scale (FAS), examined the association between family allocentrism and adjustment outcomes, and compared the factor means and the correlations with adjustment between Chinese and Italian adolescents. To this end, 484 Chinese and 480 Italian adolescents participated in the study by answering a battery of self-report measures. The results confirmed the one-factor structure of the FAS. Family allocentrism was related to a number of adjustment outcomes. More importantly, Chinese adolescents reported more family allocentrism than their Italian counterparts did, but the relations between family allocentrism and adjustment outcomes were equivalent in magnitude between the two samples. Collectively, these findings provide crucial evidence for the psychometric properties of the FAS and shed light on the importance of family allocentrism in promoting positive youth development from a cross-cultural perspective.

    Yu, Doris S F; Kwok, Timothy; Choy, Jacky; Kavanagh, David J

    2016-03-01

    Expressed emotion (EE) captures the affective quality of the relationship between family caregivers and their care recipients and is known to increase the risk of poor health outcomes for caregiving dyads. Little is known about expressed emotion in the context of caregiving for persons with dementia, especially in non-Western cultures. The Family Attitude Scale (FAS) is a psychometrically sound self-reporting measure for EE. Its use in the examination of caregiving for patients with dementia has not yet been explored. This study was performed to examine the psychometric properties of the Chinese version of the FAS (FAS-C) in Chinese caregivers of relatives with dementia, and its validity in predicting severe depressive symptoms among the caregivers. The FAS was translated into Chinese using Brislin's model. Two expert panels evaluated the semantic equivalence and content validity of this Chinese version (FAS-C), respectively. A total of 123 Chinese primary caregivers of relatives with dementia were recruited from three elderly community care centers in Hong Kong. The FAS-C was administered with the Chinese versions of the 5-item Mental Health Inventory (MHI-5), the Zarit Burden Interview (ZBI) and the Revised Memory and Behavioral Problem Checklist (RMBPC). The FAS-C had excellent semantic equivalence with the original version and a content validity index of 0.92. Exploratory factor analysis identified a three-factor structure for the FAS-C (hostile acts, criticism and distancing). Cronbach's alpha of the FAS-C was 0.92. Pearson's correlation indicated that there were significant associations between a higher score on the FAS-C and greater caregiver burden (r=0.66, p47 with a sensitivity of 0.720 (95% CI=0.506-0.879) and specificity of 0.742 (95% CI=0.643-0.826). The FAS-C is a reliable and valid measure to assess the affective quality of the relationship between Chinese caregivers and their relatives with dementia. It also has acceptable predictability in

    We report here the clinical, genetic, and molecular characterization of three Chinese families with maternally transmitted Leber's hereditary optic neuropathy (LHON). Clinical and genetic evaluations revealed the variable severity and age-of-onset in visual impairment in these families. In the affected matrilineal relatives, the loss of central vision is bilateral, the fellow eye becoming affected either simultaneously (45%) or sequentially (55%). The penetrances of vision loss in these pedigrees were 27%, 50%, and 60%, respectively. The age-at-onset of vision loss in these families was 14, 19, and 24 years, respectively. Furthermore, the ratios between affected male and female matrilineal relatives were 1:1, 1:1.2, and 1:2, respectively. Mutational analysis of mitochondrial DNA revealed the presence of homoplasmic ND6 T14484C mutation, which has been associated with LHON. The incomplete penetrance and phenotypic variability implicate the involvement of nuclear modifier gene(s), environmental factor(s) or mitochondrial haplotype(s) in the phenotypic expression of the LHON-associated T14484C mutation in these Chinese pedigrees

    This study aims to explore the factors associated with depression among older persons in Macau, in relation to family and social aspects. Depression among community-dwelling older persons in Macau has been shown to be present at high rates. In Chinese culture, depression leads to social stigmatisation, suggesting a need to better understand depression as a sociocultural phenomenon. A mixed methods study was undertaken to identify the key influences on depression among Chinese older persons in Macau. Quantitative (standardised tests) and qualitative (collection of narratives) data were collected from 31 purposively selected participants, all community-dwelling older persons with depression. Depression was common among the participants. The paper reports on the family and social aspects, one of the findings of the study. Informants readily described their thoughts and judgements of themselves in graphic language. As they explored their life stories, family and social aspects emerged as significant influences that associated with depression. In a society and culture that relies on and values filial support, experiences of being widowed, having poor family support and weak social networks appeared to compound and exacerbate depression. These findings highlight that filial support, valued in Chinese culture, is seriously strained by the realities of contemporary society. Yet current government policies rely on and confirm the role of family support. Findings from this study suggest a need for such policies to be reviewed to address the realities of family and social support. The findings have several implications for clinical practice. Firstly, the cultural context of Chinese older persons should be considered and emphasised in nursing practice. Secondly, the root of depression among Chinese older persons is seen to lie in their social, family, cultural and day-to-day living issues. © 2012 Blackwell Publishing Ltd.

  13. Economic development with limited supplies of family labor: Chinese peasant families in balancing demographic and economic requisites.

    Science.gov (United States)

    Chang, K S

    1991-07-01

    Family planning (FP) in rural China, particularly the ramifications of the 1-child policy, has profound implications and ramifications for family-centered social and economic life in addition to demographic control. Under a constitutionally endorsed policy of strict birth control, favorable economic opportunities coexisted with the problem of familial labor shortages. Recent reform policies have led to a more relaxed FP environment. The Chinese state is in a dilemma between the need to allow peasant's autonomy in determining the familial work situation and the population pressure on the limited cultivated land. The Chinese experience of rural reform is examined in terms of the complex relationship between population change and economic development which are influenced by the production and welfare activities of the peasant family. The theoretical argument is that a family reliant strategy of economic reform undercuts the effectiveness of population control programs. The ultimate solution lies with sustained industrialization with high labor absorption. National trends and the Dahe People's Commune/Township experience are analyzed. Discussion is focused on the dilemma of FP and family production, old and new evidence of family size and economic performance, welfare outcome of family size, the role of the state in altering the demographic balance sheet, and the strategic response of peasant families to bring families of old designs back and urban migration and proletarianization. It is concluded that there is growing understanding that the causal relationships between population growth and economic development do not clearly support universal population control. Human social organization, not the man/land ratio, shapes the consequences of population growth. The implications for the Malthusian vs. Marxian debate for developing countries are that the resources/population imbalance needs to consider more carefully the human organizational factors. Mao's notions that a

  15. Family care: an exploratory study of experience and expectations among older Chinese immigrants in Australia.

    Lo, Meihan; Russell, Cherry

    2007-01-01

    Family caregiving in East Asian cultures is traditionally based on the Confucian ethic of filial piety that mandates total, holistic care for elders. While research suggests changes in 'family care' are occurring in Asian countries themselves, remarkably little is known about immigrant Asian families in Australia. The study aimed to explore the experience of 'family care' among Chinese-speaking older people who have migrated to Australia in later life. In-depth interviews were conducted in Cantonese with a convenience sample of five cases, including six older Chinese and analysed inductively for dominant themes. Although no single model of 'family care' emerged, findings reveal significant departures from the norms of filial piety and an overall 'westernisation' of care practices, both in relation to what families actually do for their parents and what the older people themselves expect. Transformation of filial culture has implications for policy, service planning and professional practice. It cannot be assumed that elderly Chinese immigrants' needs are being met through traditional family structures.

    2007-10-01

    Hereditary sensory and autonomic neuropathy type I (HSAN I) is an autosomal dominant disorder of the peripheral nervous system characterized by marked progressive sensory loss, with variable autonomic and motor involvement. The HSAN I locus maps to chromosome 9q22.1-22.3 and is caused by mutations in the gene coding for serine palmitoyltransferase long chain base subunit 1 (SPTLC1). Sequencing in HSAN I families have previously identified mutations in exons 5, 6 and 13 of this gene. Here we report the clinical, electrophysiological and pathological findings of a proband in a Chinese family with HSAN I. The affected members showed almost typical clinical features. Electrophysiological findings showed an axonal, predominantly sensory, neuropathy with motor and autonomic involvement. Sural nerve biopsy showed loss of myelinated and unmyelinated fibers. SPTLC1 mutational analysis revealed the C133W mutation, a mutation common in British HSAN I families.

    This pilot study explores the roles of family socioeconomic status (SES) in influencing dietary consumption patterns in 60 Chinese elementary school-aged children (ages 6-11) in Chengdu, China. Two interviewer-administered questionnaires were specially developed to gather sociodemographic and food frequency data. Children from low SES families consumed rice and traditional staples, and high calcium drinks more frequently, and western fast food less frequently than children from higher SES families. After controlling for family SES, children who were primarily cared for by their mothers or grandparents consumed less healthy snacks less frequently than children who were primarily cared for by other adults (including fathers).

  18. Chinese traders in Serbia: Gender opportunities, translocal family strategies, and transnational mobility

    Directory of Open Access Journals (Sweden)

    Maja Korać-Sanderson

    2013-12-01

    In this paper I focus on Chinese trading migration to Serbia. I argue that in choosing destinations for their businesses Chinese traders increasingly opt for underdeveloped regions and transition societies not because they provide good business opportunities measured by economic indicators alone. Rather, these destinations are chosen because they provide better opportunities for an entrepreneurial life embedded in self-reliance and self-management. Some of these opportunities, as my discussion will demonstrate, are importantly gendered, opening up new gender space for young families and for women in particular. My discussion will further point out that because business opportunities in Serbia do not necessarily imply desirable living conditions, Chinese traders diversify their family strategies, which are translocally and transnationally negotiated. In doing so, I argue, they become protagonists, actively involved in establishing their livelihoods and flexible ways of incorporation.

    2016-12-01

    To describe family involvement in decision making for primary treatment in Chinese-American women with early-stage breast cancer. Qualitative data were collected in 2003 from semi-structured questions in interviews with a sample of Chinese-American (ChA) women with breast cancer, who were recruited from the metropolitan New York area. Responses to the questions were written in Chinese immediately during the interview and read back to the subject for accuracy and validation. Content analysis was used to inductively code and analyze the data to generate themes. The participants consisted of 123 ChA women with early stage breast cancer with a mean age of 48.7 years (±9.3) and who had lived in the United States a median of 13.6 years. Support and Caring was the major theme that described family involvement in the breast cancer decision-making process. Gathering Information, Being There, Navigating the Health Care System, Maintaining Family Life and Making the Decision described the aspects of family support in the process. The majority of women described the treatment decision making as a collaborative supportive process with the family, but limited English fluency, strong opinions, lack of a shared perspective, distant living proximity and competing work responsibilities of family members were stressful for the women and perceived as non-supportive. Family involvement in health care decision making is culturally embedded in Asian populations. Culturally sensitive patient and family consultation strategies are needed to assist informed treatment decision making in Chinese-American women diagnosed with breast cancer.

    Full Text Available Based on the responses of 5,557 Chinese secondary students in Hong Kong, the relationships between perceived family functioning (systemic correlate, parent-adolescent communication (dyadic correlate, and suicidal ideation were examined in this study. Results showed that suicidal ideation was negatively related to global family functioning and parent-adolescent communication. Regression analyses indicated that the dyadic and systemic factors had similar importance in predicting suicidal ideation. Theoretical and practical implications of the findings are discussed.

    2015-05-01

    In the UK, public health nurses (health visitors) provide support and advice to families with young children, including those from minority ethnic communities. While the need for cultural sensitivity is being increasingly recognized, the factors which contribute to this sensitivity are poorly understood. The Pakistani and Chinese communities constitute the two largest minority ethnic groups in Scotland. This study explored Pakistani and Chinese women's experience of motherhood and of the health visiting service and public health nurses' experiences of working with Chinese and Pakistani mothers. Semi-structured individual interviews were carried out with 16 Pakistani and 15 Chinese mothers. Eight health visitors took part in two focus groups. The study was undertaken in an urban area of Scotland. Data were analysed thematically. Chinese and Pakistani mothers negotiate complex processes in order to ensure that their children maintain their own ethnic identity while fitting in with their peers in their adopted country. Health visitors were seen as supportive, although sometimes advice and information given was culturally inappropriate, and their role was often poorly understood. Health visitors were anxious to be sensitive to families' religious and cultural beliefs. Cultural sensitivity is an important factor in providing appropriate advice and help to Pakistani and Chinese families, and involves health visitors in considering views and practices on parenting which may differ across cultures, including their own. Family characteristics need to be understood on an individual basis, rather than making assumptions about clients' cultural norms and lifestyles. This is best achieved by exploring with mothers if they understand the advice and information they are being offered and also if it is appropriate to their cultural and religious beliefs. © 2014 John Wiley & Sons Ltd.

    2018-01-01

    To explore and describe the caregiving experiences of Chinese stroke caregivers. Previous research has indicated that culture can have a significant impact on the stroke caregiving experience. Moreover, scant research exists on stroke caregivers' experience within the Chinese culture. A qualitative descriptive design was used. In-depth, semistructured interviews were conducted with 25 family caregivers of stroke survivors. The interviews were audiotaped, transcribed and analysed. Content analysis was also performed. Twenty-five family caregivers of stroke survivors were recruited for the study. On average, respondents were 66 years old (range 45-82 years). Of 25 interviewees, 76% were female, 64% were spouse-caregivers and 36% were children-caregivers. Three themes reflecting the influence of Chinese culture on stroke caregiving emerged from the interviews. (i) Caregiving role perception. Informants accepted caregiving for the sick family member as an expected part of life, a culturally prescribed obligation and an expression of reciprocal love. (ii) Coping strategies. Connecting with family resources and connecting with inner strength were frequently reported coping strategies. (iii) Self-sacrifice. Informants identified self-reliance and feeling of restraint in their utilisation or access of formal caregiving service. Chinese caregivers sacrifice themselves for the care recipients regardless of the hardships and the neglect of their own health. Our findings provide a comprehensive and culturally sensitive perspective in understanding the experience of stroke caregivers in Chinese communities. Cultural and religious backgrounds were found to influence Chinese stroke caregivers' experience, coping strategies and self-sacrifice behaviour in idiosyncratic ways. Research on the practice of culture can serve as a basis for the formulation of specific policies and effective interventions for supporting stroke caregivers of different cultural backgrounds. © 2017 John

  17. The changing meaning of family support among older Chinese and Korean immigrants.

    Science.gov (United States)

    Wong, Sabrina T; Yoo, Grace J; Stewart, Anita L

    2006-01-01

    Our objective in this study was to examine how family social-support expectations have changed among older Chinese and Korean U.S. immigrants. Fifty-two Cantonese- and Korean-speaking immigrants older than 60 years participated in eight focus groups. Transcripts were translated into English. Themes were developed based on a coding structure and compared to past research. Participants discussed changed perspectives of family social support and the need to integrate both American and Chinese or Korean culture, thus becoming bicultural. Three distinct perspectives of family emerged: (1) participants felt they had become peripheral family members, (2) parents were no longer authority figures in families, and (3) participants were more independent. Finally, participants described how factors such as a changed economic environment, living alone, and extending their social network beyond family, promoted a move to biculturalism. These results suggest that the integration of two cultures, or biculturalism, is an indicator of successful adaptation to immigration later in life; older Chinese and Korean immigrants are adjusting to living in the United States and blending multiple cultures simultaneously. Thus, acculturation frameworks implying a linear process may not be theoretically valid as ethnic identity, particularly for those who immigrate to different countries, changes over the life course.

    Burnout among nurses not only threatens their own health, but also that of their patients. Exploring risk factors of nurse' burnout is important to improve nurses' health and to increase the quality of health care services. This study aims to explore the relationship between work-family conflict and burnout among Chinese female nurses and the mediating role of psychological capital in this relationship. This cross-sectional study was performed during the period of September and October 2010. A questionnaire that consisted of the Maslach Burnout Inventory-General Survey (MBI-GS), the work-family conflict scale and the psychological capital questionnaire (PCQ-24) scale, as well as demographic and working factors, was distributed to nurses in Liaoning province, China. A total of 1,332 individuals (effective response rate: 78.35%) became our subjects. Hierarchical linear regression analyses were performed to explore the mediating role of psychological capital. Both work interfering family conflict and family interfering work conflict were positively related with emotional exhaustion and cynicism. However, work interfering family conflict was positively related with professional efficacy whereas family interfering work conflict was negatively related with it. Psychological capital partially mediated the relationship of work interfering family conflict with emotional exhaustion and cynicism; and partially mediated the relationship of family interfering work conflict with emotional exhaustion, cynicism and professional efficacy. Work-family conflict had effects on burnout and psychological capital was a mediator in this relationship among Chinese nurses. Psychological capital was a positive resource for fighting against nurses' burnout.

  19. A unified framework for haplotype inference in nuclear families.

    2012-07-01

    Many large genome-wide association studies include nuclear families with more than one child (trio families), allowing for analysis of differences between siblings (sib pair analysis). Statistical power can be increased when haplotypes are used instead of genotypes. Currently, haplotype inference in families with more than one child can be performed either using the familial information or statistical information derived from the population samples but not both. Building on our recently proposed tree-based deterministic framework (TDS) for trio families, we augment its applicability to general nuclear families. We impose a minimum recombinant approach locally and independently on each multiple children family, while resorting to the population-derived information to solve the remaining ambiguities. Thus our framework incorporates all available information (familial and population) in a given study. We demonstrate that using all the constraints in our approach we can have gains in the accuracy as opposed to breaking the multiple children families to separate trios and resorting to a trio inference algorithm or phasing each family in isolation. We believe that our proposed framework could be the method of choice for haplotype inference in studies that include nuclear families with multiple children.

    Highlights: Black-Right-Pointing-Pointer In our study, all of the patients were of Han Chinese ethnicity, which were rarely reported. Black-Right-Pointing-Pointer We identified three novel PHEX gene mutations in four unrelated families with XLH. Black-Right-Pointing-Pointer We found that the relationship between the phenotype and genotype of the PHEX gene was not invariant. Black-Right-Pointing-Pointer We found that two PHEX gene sites, p.534 and p.731, were conserved. -- Abstract: Background: X-linked hypophosphatemia (XLH), the most common form of inherited rickets, is a dominant disorder that is characterized by renal phosphate wasting with hypophosphatemia, abnormal bone mineralization, short stature, and rachitic manifestations. The related gene with inactivating mutations associated with XLH has been identified as PHEX, which is a phosphate-regulating gene with homologies to endopeptidases on the X chromosome. In this study, a variety of PHEX mutations were identified in four Chinese families with XLH. Methods: We investigated four unrelated Chinese families who exhibited typical features of XLH by using PCR to analyze mutations that were then sequenced. The laboratory and radiological investigations were conducted simultaneously. Results: Three novel mutations were found in these four families: one frameshift mutation, c.2033dupT in exon 20, resulting in p.T679H; one nonsense mutation, c.1294A > T in exon 11, resulting in p.K432X; and one missense mutation, c.2192T > C in exon 22, resulting in p.F731S. Conclusions: We found that the PHEX gene mutations were responsible for XLH in these Chinese families. Our findings are useful for understanding the genetic basis of Chinese patients with XLH.

    Nuclear organization was probed in the radiation-sensitive Chinese hamster ovary (CHO) cell line, xrs-5, and compared with parental CHO K1 cells using the resinless section technique and DNase I digestions. The resinless section data showed no gross morphological differences in core filaments from the nuclear scaffolds of unirradiated CHO K1 and xrs-5 cells. However, the nuclear scaffolds of irradiated xrs-5 cells (1 Gy) had significantly increased ground substance. Irradiated and unirradiated CHO K1 cell nuclear scaffolds were morphologically identical. These data suggest that both CHO K1 and xrs-5 cell nuclear scaffolds had internal nuclear scaffolding networks that could provide DNA attachment sites. (author)

    Here, we reported a Han Chinese essential hypertensive pedigree based on clinical hereditary and molecular data. To know the molecular basis on this family, mitochondrial genome of one proband from the family was identified through direct sequencing analysis. The age of onset year and affected degree of patients are different in this family. And matrilineal family members carrying C4375T mutation and belong to Eastern Asian halopgroup C. Phylogenetic analysis shows 4375C is highly conservative in 17 species. It is suggested that these mutations might participate in the development of hypertension in this family. And halopgroup C might play a modifying role on the phenotype in this Chinese hypertensive family.

    The Chinese community, a heterogeneous, highly visible non-English speaking ethnic group in Australia, remains mostly hidden and underrepresented in palliative care service delivery along with participation in health research despite being the fastest growing such group in the country. There is a lack of Australian research information concerning the impact of migration on the caregiving experience of women carers within the Chinese cultural framework and the Australian palliative care context. This paper aims to explore the influence of Chinese cultural norms and immigration on the experience of immigrant women of Chinese ancestry caring for a terminally ill family member at home in Sydney. This study also seeks to identify factors that may present access barriers to palliative care support services. A qualitative approach was used in this study. Data were collected from semi-structured interviews with five home-based Chinese women carers and were analysed using thematic analysis. Findings identified that the participants found being a carer is a lonely and isolating experience. Sources of isolation and loneliness included social isolation experienced as a solitary carer without meaningful family and social relationships; loss of familiar cultural understandings and family values; and emotional isolators expressed in response to the physical and emotional role commitment and other constraints. The study results suggest the need for palliative care educational programmes designed to help nurses to understand the impact of cultural background within the palliative care context. Results also indicate that health care professionals should provide culturally appropriate and competent palliative care services, sensitive to the diverse socio-cultural influences and individual needs of Chinese migrants.

    Waardenburg syndrome (WS) is an auditory-pigmentary disorder with varying combinations of sensorineural hearing loss and abnormal pigmentation. The present study aimed to investigate the underlying molecular pathology and provide a method of prenatal diagnosis of WS in Chinese families. A total of 11 patients with WS from five unrelated Chinese families were enrolled. A thorough clinical examination was performed on all participants. Furthermore, patients with WS underwent screening for mutations in the following genes: Paired box 3 (PAX3), melanogenesis associated transcription factor (MITF), SRY-box 10, snail family transcriptional repressor 2 and endothelin receptor type B using polymerase chain reaction sequencing. Array-based comparative genomic hybridization was used for specific patients whose sequence results were normal. Following identification of the genotype of the probands and their parents, prenatal genetic diagnosis was performed for family 01 and 05. According to the diagnostic criteria for WS, five cases were diagnosed as WS1, while the other six cases were WS2. Genetic analysis revealed three mutations, including a nonsense mutation PAX3 c.583C>T in family 01, a splice-site mutation MITF c.909G>A in family 03 and an in-frame deletion MITF c.649_651delGAA in family 05. To the best of the authors' knowledge the mutations (c.583C>T in PAX3 and c.909G>A in MITF) were reported for the first time in Chinese people. Mutations in the gene of interest were not identified in family 02 and 04. The prenatal genetic testing of the two fetuses was carried out and demonstrated that the two babies were normal. The results of the present study expanded the range of known genetic mutations in China. Identification of genetic mutations in these families provided an efficient way to understand the causes of WS and improved genetic counseling. PMID:29115496

    Full Text Available Background. This study examines the association between family structure and moderate-to-vigorous physical activity (MVPA of adolescents in China. Methods. The participants included 612 adolescents (317 boys and 295 girls from Shanghai with ages ranging from 10 to 16 years. Accelerometers were used to measure the duration of MVPA of adolescents, and questionnaires on family structure were completed by the parents of these adolescents. Results. Findings suggested that family structure significantly increased the likelihood of adolescents engaging in physical activity (PA and explained 6% of MPVA variance. Adolescents living in single-parent households and step families were more physically active than those living in two-parent homes and with biological parents, respectively. However, adolescents residing with grandparents were less active than those living with neither grandparent. No significant difference was found in MVPA time between adolescents living with one sibling and those without siblings. Conclusion. Family environment may be considered in the development of PA interventions and policies, and adolescents living with their grandparents may be targeted in PA promotion.

    We examined the relationships between parent-adolescent discrepancies in perceived parenting characteristics (indexed by parental responsiveness, parental demandingness, and parental control) and adolescent developmental outcomes (indexed by achievement motivation and psychological competence) in poor families in Hong Kong. A sample of 275 intact families having at least one child aged 11-16 experiencing economic disadvantage were invited to participate in the study. Fathers and mothers completed the Parenting Style Scale and Chinese Parental Control Scale, and adolescents completed the Social-Oriented Achievement Motivation Scale and Chinese Positive Youth Development Scale in addition to paternal and maternal Parenting Style Scale and Chinese Parental Control Scale. Results indicated that parents and adolescents had different perceptions of parental responsiveness, parental demandingness, and paternal control, with adolescents generally perceived lower levels of parenting behaviors than did their parents. While father-adolescent discrepancy in perceived paternal responsiveness and mother-adolescent discrepancy in perceived maternal control negatively predicted adolescent achievement motivation, mother-adolescent discrepancy in perceptions of maternal responsiveness negatively predicted psychological competence in adolescents experiencing economic disadvantage. The present findings provided support that parent-child discrepancies in perceived parenting characteristics have negative impacts on the developmental outcomes of adolescents experiencing economic disadvantage. The present study addresses parent-child discrepancies in perceived parental behaviors as "legitimate" constructs, and explores their links with adolescent psychosocial development, which sheds light for researchers and clinical practitioners in helping the Chinese families experiencing economic disadvantage.

    The purpose of the current research was to investigate the NDP (Norrie disease protein) gene in one Chinese family with Norrie disease (ND) and to characterize the related clinical features. Clinical data of the proband and his family members were collected. Complete ophthalmic examinations were carried out on the proband. Genomic DNA was extracted from peripheral blood leukocytes of 35 family members. Molecular analysis of the NDP gene was performed by polymerase chain reaction and direct sequencing of all exons and flanking regions. A hemizygous NDP missense mutation c.362G > A (p.Arg121Gln) in exon 3 was identified in the affected members, but not in any of the unaffected family individuals. The missense mutation c.362G > A in NDP is responsible for the Norrie disease in this family. This discovery will help provide the family members with accurate and reliable genetic counseling and prenatal diagnosis.

Developmental outcomes included positive youth development constructs, problem behaviors, perceived family interaction, and parental parenting. Results showed that adolescents experiencing poverty did not differ from nonpoor adolescents in terms of risk behavior and in most indicators of positive youth development. On the other hand, adolescents with economic disadvantage displayed lower levels of positive identity, family interaction, and perceived paternal parenting than did those without economic disadvantage.

    Full Text Available Abstract Background The family plays a vital role in shaping adolescent behaviours. The present study investigated the associations between family structure and substance use among Hong Kong Chinese adolescents. Methods A total of 32,961 Form 1 to 5 (grade 7-12 in the US Hong Kong students participated in the Youth Smoking Survey in 2003-4. An anonymous questionnaire was used to obtain information about family structure, daily duration of parent-child conversation, smoking, alcohol drinking and drug use. Logistic regression was used to calculate the adjusted odds ratios (OR for each substance use by family structure. Results Adjusting for sex, age, type of housing, parental smoking and school, adolescents from non-intact families were significantly more likely to be current smokers (OR = 1.62, weekly drinkers (OR = 1.72 and ever drug users (OR = 1.72, with significant linear increases in ORs from maternal, paternal to no-parent families compared with intact families. Furthermore, current smoking (OR = 1.41 and weekly drinking (OR = 1.46 were significantly more common among adolescents from paternal than maternal families. After adjusting for parent-child conversation time, the ORs for non-intact families remained significant compared with intact families, but the paternal-maternal differences were no longer significant. Conclusions Non-intact families were associated with substance use among Hong Kong Chinese adolescents. The apparently stronger associations with substance use in paternal than maternal families were probably mediated by the poorer communication with the father.

  13. On the validity of within-nuclear-family genetic association analysis in samples of extended families.

    Bureau, Alexandre; Duchesne, Thierry

    2015-12-01

    Splitting extended families into their component nuclear families to apply a genetic association method designed for nuclear families is a widespread practice in familial genetic studies. Dependence among genotypes and phenotypes of nuclear families from the same extended family arises because of genetic linkage of the tested marker with a risk variant or because of familial specificity of genetic effects due to gene-environment interaction. This raises concerns about the validity of inference conducted under the assumption of independence of the nuclear families. We indeed prove theoretically that, in a conditional logistic regression analysis applicable to disease cases and their genotyped parents, the naive model-based estimator of the variance of the coefficient estimates underestimates the true variance. However, simulations with realistic effect sizes of risk variants and variation of this effect from family to family reveal that the underestimation is negligible. The simulations also show the greater efficiency of the model-based variance estimator compared to a robust empirical estimator. Our recommendation is therefore, to use the model-based estimator of variance for inference on effects of genetic variants.

    The novel compound heterozygous mutation in PAX3 was the key genetic reason for WS1 in this family, which was useful to the molecular diagnosis of WS1. Screening the pathogenic mutations in a four generation Chinese family with Waardenburg syndrome type I (WS1). WS1 was diagnosed in a 4-year-old boy according to the Waardenburg syndrome Consortium criteria. The detailed family history revealed four affected members in the family. Routine clinical, audiological examination, and ophthalmologic evaluation were performed on four affected and 10 healthy members in this family. The genetic analysis was conducted, including the targeted next-generation sequencing of 127 known deafness genes combined with Sanger sequencing, TA clone and bioinformatic analysis. A novel compound heterozygous mutation c.[169_170insC;172_174delAAG] (p.His57ProfsX55) was identified in PAX3, which was co-segregated with WS1 in the Chinese family. This mutation was absent in the unaffected family members and 200 ethnicity-matched controls. The phylogenetic analysis and three-dimensional (3D) modeling of Pax3 protein further confirmed that the novel compound heterozygous mutation was pathogenic.

    This study examines two sources of informal support-perceived family and friend support-and the psychological well-being-self-esteem, depression and loneliness-of 150 Chinese and 145 American elders. There were no significant differences between the elderly American and Chinese persons' mean scores on family and friend support. The multiple linear regression analyses with interaction terms (country x family support and country x friend support), however, indicated that the relationship between family support and depression and family support and loneliness was stronger for the Chinese elderly than the US elderly. Conversely, the relationship between friend support and depression and friend support and loneliness is stronger for US elderly than Chinese elderly. The implications of these findings for social work practice in both countries is discussed.

    To detect the pathogenic mutation in a Chinese family with Norrie disease. Clinical diagnosis was based on familial history, clinical sign and B ultrasonic examination. Peripheral blood samples were obtained from all available members in a Chinese family with Norrie disease. Genomic DNA was extracted from lymphocytes by the standard SDS-proteinase K-phenol/chloroform method. Two coding exons and all intron-exon boundaries of the NDP gene were PCR amplified using three pairs of primers and subjected to automatic DNA sequence. The causative mutation was confirmed by restriction enzyme analysis and genotyping analysis in all members. Sequence analysis of NDP gene revealed a missense mutation c.220C > T (p.Arg74Cys) in the proband and his mother. Further mutation identification by restriction enzyme analysis and genotyping analysis showed that the proband was homozygote of this mutation. His mother and other four unaffected members (III3, IV4, III5 and II2) were carriers of this mutation. The mutant amino acid located in the C-terminal cystine knot-like domain, which was critical motif for the structure and function of NDP. A NDP missense mutation was identified in a Chinese family with Norrie disease.

    The present study aimed to investigate the stress and coping strategies of Hong Kong Chinese families during a critical illness and to examine the relationships between stress and coping. Admissions to intensive care unit are usually an unanticipated event, which imposes stress on the family. Family's wellness is one of the significant factors affecting patient's well-beings. Much work has been conducted in Western societies. Stress and coping in Chinese families of critically ill patients have rarely been discussed. Structured face-to-face interviews were conducted, using the Impact of Events Scale and the Family Crisis Oriented Personal Evaluation Scales. A convenience sample of 133 participants was recruited from a regional hospital in Hong Kong. Many were patients' children with age between 30 and 49. A total of 39.1% (n = 52) of the participants were males and 60.9% (n = 81) were females. The participants experienced high level of stress (mean = 25.1, SD = 8.3). Higher level of stress were experienced by female (t = -4.6; d.f. = 1, 131; P = 0.00), those with lower educational attainment (F = 3.0; d.f. = 2, 130; P = 0.05) and those whose relatives were admitted to the intensive care unit unexpectedly (t = -2.2; d.f. = 1; P = 0.03). Patients' length of stay in the unit was significantly correlated with levels of stress (r = 0.5, P stress had significant correlation with coping strategies utilization (r = 0.5, P stress-coping pattern 'fatalistic voluntarism'. This study contributes to the understanding of Hong Kong Chinese families' stress and coping during a critical illness. Comprehensive assessments of family members' psychosocial needs are important to plan appropriate interventions to alleviate their stress and strengthen their coping skills. The findings will serve as guidance for nurses in delivering culturally sensitive and competent interventions.

    The Obama administration is putting nuclear disarmament back on the agenda. In a major speech in Prague in April 2009, he envisioned a world free of nuclear weapons and called on nations to work toward that end. Reversing years of setbacks and stagnation, Washington and Moscow agreed on renewing negotiation on extending the START I Treaty last year and concluded the New START treaty in March 2010. The 2010 Nuclear Posture Review indicates a shift in U.S. nuclear doctrine in that Washington pledges not to use nuclear weapons against non-nuclear weapons states that abide by the Nuclear Nonproliferation Treaty. The prospects of nuclear disarmament look much promising as the momentum generated could also exert pressure on the second-tier nuclear-weapon States: Britain, France, and China. Beijing's responses to these developments have been favorable, viewing them as positive contribution to international nuclear disarmament and nonproliferation. In particular China endorses President Obama's call for securing global nuclear materials and safeguarding vulnerable nuclear facilities to prevent nuclear terrorism. However, Chinese perspectives and policies on important international nuclear arms control and disarmament, and on the role of nuclear weapons and nuclear deterrence remain largely declaratory and less specific on its own commitments and participation. Chinese analyses, at the same time, point out the difficulties ahead on the road toward a nuclear weapons free world. Indeed, rhetoric notwithstanding, Beijing continues to modernize its nuclear arsenal to develop a secure and reliable second-strike deterrence capability. This paper takes a careful look at China's perceptions of the role of nuclear weapons in its national security policy and defense posture. This is important because China is perceived to be the only country among the five original nuclear-weapon States that is actually expanding its nuclear arsenal, as indicated by the recent

    Using data from a socioeconomically diverse sample of Chinese American children (n = 258, aged 6-9 years) in immigrant families, we examined the concurrent relations among neighborhood economic disadvantage and concentration of Asian residents, parenting styles, and Chinese American children's externalizing and internalizing problems. Neighborhood characteristics were measured with 2000 U.S. Census tract-level data, parents (mostly mothers) rated their own parenting styles, and parents and teachers rated children's behavioral problems. Path analysis was conducted to test two hypotheses: (a) parenting styles mediate the relations between neighborhood characteristics and children's behavioral problems, and (b) children's behavioral problems mediate the relations between neighborhood and parenting styles. We found that neighborhood Asian concentration was positively associated with authoritarian parenting, which in turn was associated with Chinese American children's higher externalizing and internalizing problems (by parents' reports). In addition, neighborhood economic disadvantage was positively related to children's externalizing problems (by parents' reports), which in turn predicted lower authoritative parenting. The current results suggest the need to consider multiple pathways in the relations among neighborhood, family, and child adjustment, and they have implications for the prevention and intervention of behavioral problems in Chinese American children.

    Direct and indirect/mediated relations of (a) children's and parents' cultural orientations and (b) parent-child gaps in cultural orientations to children's psychological adjustment were examined in a socioeconomically diverse sample of 258 Chinese American children (age = 6-9 years) from immigrant families. Parents reported on children's and their own Chinese and American orientations in language proficiency, media use, and social relationships. Parents and teachers rated children's externalizing and internalizing problems and social competence. Using structural equation modeling, we found evidence for both the effects of children's and parents' cultural orientations and the effects of parent-child gaps. Specifically, children's American orientations across domains were associated with their better adjustment (especially social competence). These associations were partly mediated by authoritative parenting. Parents' English and Chinese media use were both associated with higher authoritative parenting, which in turn was associated with children's better adjustment. Furthermore, greater gaps in parent-child Chinese proficiency were associated with children's poorer adjustment, and these relations were partly mediated by authoritative parenting. Together, the findings underscore the complex relations between immigrant families' dual orientations to the host and heritage cultures and children's psychological adjustment.

    The aim of this study was to investigate the relation between work-family conflict and burnout, and the mediating role of psychological capital (PsyCap) in the relation between work-family conflict and burnout, among Chinese doctors. This cross-sectional study was performed during the period of September/October 2010. A questionnaire that comprised work-family conflict assessed by the work-family conflict scale, PsyCap assessed by the PCQ-24 scale and burnout assessed by the Maslach Burnout Inventory-General Survey (MBI-GS), as well as age and gender, was distributed to 1,300 doctors in Liaoning Province, China. A total of 1,011 effective respondents became our final study subjects. Hierarchical linear regression analyses were performed by using SPSS 17.0 to explore the mediating role of PsyCap in the relation between work-family conflict and burnout. Both work interfering family conflict (WIF) and family interfering work conflict (FIW) were positively related with emotional exhaustion and cynicism among both male and females doctors. However, WIF was positively related with professional efficacy only among male doctors, whereas FIW was negatively related with professional efficacy among both male and female doctors. PsyCap partially mediated the relation between WIF and professional efficacy among male doctors and partially mediated the relations of FIW with emotional exhaustion, cynicism and professional efficacy among female doctors. Work-family conflict was associated with burnout among Chinese doctors. PsyCap was a mediator between work-family conflict and burnout. PsyCap might be a positive resource to reduce the negative effect of work-family conflict on burnout of doctors, especially female doctors, in China.

    This study examined the mediating role of coparenting in the association between differences/similarities in paternal and maternal socioeconomic status (SES) and paternal involvement in Chinese families. The sample included 244 couples with children aged 3-7 years. Fathers and mothers reported their individual incomes, educational levels, occupations, and coparenting behavior (measured using the Coparenting Scale), and fathers completed the Father Involvement Questionnaire. Structural equation modeling was performed to examine the associations between SES and paternal involvement. Results suggested that SES indicator measures were outcome specific. Occupational differences/similarities were associated with paternal involvement indirectly, via fathers' family integrity practices. Income and educational differences/similarities did not affect paternal involvement. The results suggested that the traditional Chinese view that "men are chiefly responsible for activity in society, while women are responsible for the home" has faded.

    Purpose Norrie disease (ND), a rare X-linked recessive disorder, is characterized by congenital blindness and, occasionally, mental retardation and hearing loss. ND is caused by the Norrie Disease Protein gene (NDP), which codes for norrin, a cysteine-rich protein involved in ocular vascular development. Here, we report a novel mutation of NDP that was identified in a Chinese family in which three members displayed typical ND symptoms and other complex phenotypes, such as cerebellar atrophy, ...

    To identify the disease-causing gene in a four-generation Chinese family affected with retinitis pigmentosa (RP). Linkage analysis was performed with a panel of microsatellite markers flanking the candidate genetic loci of RP. These loci included 38 known RP genes. The complete coding region and exon-intron boundaries of Usher syndrome 2A (USH2A) were sequenced with the proband DNA to screen the disease-causing gene mutation. Restriction fragment length polymorphism (RFLP) analysis and direct DNA sequence analysis were done to demonstrate co-segregation of the USH2A mutations with the family disease. One hundred normal controls were used without the mutations. The disease-causing gene in this Chinese family was linked to the USH2A locus on chromosome 1q41. Direct DNA sequence analysis of USH2A identified two novel mutations in the patients: one missense mutation p.G1734R in exon 26 and a splice site mutation, IVS32+1G>A, which was found in the donor site of intron 32 of USH2A. Neither the p.G1734R nor the IVS32+1G>A mutation was found in the unaffected family members or the 100 normal controls. One patient with a homozygous mutation displayed only RP symptoms until now, while three patients with compound heterozygous mutations in the family of study showed both RP and hearing impairment. This study identified two novel mutations: p.G1734R and IVS32+1G>A of USH2A in a four-generation Chinese RP family. In this study, the heterozygous mutation and the homozygous mutation in USH2A may cause Usher syndrome Type II or RP, respectively. These two mutations expand the mutant spectrum of USH2A.

    2011-01-01

    OBJECTIVES: Parents from different cultures differ in how frequently they express emotions. However, the generalizability of the relations between parental expressivity and child adjustment in non-Western cultures has not been extensively studied. The goal of the present study was to investigate prospective relations between parental expressivity within the family (positive, negative dominant, and negative submissive expressivity) and Chinese children's psychological adjustment, above and beyond parenting styles. DESIGN: The study used two waves (3.8 years apart) of longitudinal data from a sample (n= 425) of children in Beijing (mean ages = 7.7 years at T1 and 11.6 years at T2). Parental expressivity and parenting styles were self-reported. To reduce the potential measurement overlap, items that tap parental expression of emotions toward the child were removed from the parenting style measure. Children's adjustment was measured with parents', teachers', and peers' or children's reports. RESULTS: Consistent with findings with European American samples, parental negative dominant expressivity uniquely and positively predicted Chinese children's externalizing problems controlling for prior externalizing problems, parenting styles, and family SES. Neither parental expressivity nor parenting styles uniquely predicted social competence. CONCLUSIONS: Despite previously reported cultural differences in the mean levels of parental expressivity, some of the socialization functions of parental expressivity found in Western countries can be generalized to Chinese families. Although parental expressivity and parenting styles are related constructs, their unique relations to child's adjustment suggest that they should be examined as distinct processes.

    A longitudinal daily diary method was employed to examine the implications of family assistance for the academic achievement of 563 adolescents (53% female) from Mexican (n = 217), Chinese (n = 206), and European (n = 140) backgrounds during the high school years (mean age 14.9 years in 9th grade to 17.8 years in 12th grade). Although changes in family assistance time within individual adolescents were not associated with simultaneous changes in their Grade Point Averages (GPAs), increases in the proportion of days spent helping the family were linked to declines in the GPAs of students from Mexican and Chinese backgrounds. The negative implications of spending more days helping the family among these two groups was not explained by family background factors or changes in study time or school problems. These results suggest that the chronicity rather than the amount of family assistance may be difficult for adolescents from Mexican and Chinese backgrounds.

    this study aimed to explore new parents' views and experiences during their transition to parenthood. in China the one-child birth policy may bring more stress and challenges for the new parents due to the lack of experience and greater expectations of their new role. China is also at a stage of rapid economic and social development which creates new conditions for parenthood. a cross-sectional survey was conducted from February to September 2009 among 232 mothers and fathers, yielding a 83.6% response rate (n=194 couples). The questionnaire included: the Family Assessment Device-General Function Scale, the Family Resources Scale, the Family Adaptation Scale, and the Chinese Perceived Stress Scale. there were no significant differences between mothers' adaptation and fathers' adaptation during the postpartum period, as well as their perceived stress, family function and family resources (p>0.05). Method of childbirth was not related to adaptation. About 29% of variance in mothers' adaptation could be explained by satisfaction with the infant's gender (B=0.295, padaptation (B=0.236, padaptation could be explained by mothers' adaptation (B=0.268, pimportance of family resources to family adaptation and antenatal and postnatal education programmes as part of family-centred care. The possible influences of culture and policies need to be considered by health-care professionals developing strategies to facilitate family adaptation to the early parenthood.

    In the current study, we examined a moderated mediation model using the risk and resilience framework. Specifically, the impact of family material hardship on adolescent problem behaviors was examined in a Chinese sample; we used the family stress model framework to investigate parental depression and negative parenting as potential mediators of the relation between family material hardship and adolescents' problem behaviors. In addition, based on resilience theory, we investigated adolescents' resilience as a potential protective factor in the development of their internalizing and externalizing problems. Participants included 1,419 Chinese adolescents (mean age = 15.38 years, SD = 1.79) and their primary caregivers. After controlling for covariates (age, gender, location of family residence, and primary caregiver), we found that parental depression and negative parenting mediated the association between family material hardship and adolescents' problem behaviors. Furthermore, the adolescent resilience moderated the relationship between negative parenting and internalizing problems in a protective-stabilizing pattern; in addition, a protective-reactive pattern also emerged when adolescent resilience was examined as a moderator of the relationship between negative parenting and externalizing problems. These findings contribute to a comprehensive understanding of the mechanisms of risk and resilience in youth development. Moreover, the findings have important implications for the prevention of adolescent problem behaviors.

    This study examined the perception of Alzheimer's disease (AD) and caregiving among family caregivers of individuals with mild cognitive impairment (MCI) and AD in China. In-depth semistructured interviews were conducted with 46 family caregivers of individuals with cognitive impairment in 2009 in Wuhan and Beijing, China. Participants included 38 spouses, 7 adult children, and 1 sibling, aged between 41 and 85 years old. The findings showed that all family caregivers thought the Chinese terminology of AD laonian chidai, brought discrimination to individuals with cognitive impairment. Caregivers of individuals with AD experienced burden and desired an increase of formal services. Traditional beliefs of respecting elders and caring for extended family members were held among family caregivers of individuals with cognitive impairment, and there was nearly no difference found between caregivers of AD and those of MCI. It implied that traditional culture provided positive influences on caring for elders with cognitive impairment. An alternative term for MCI may contribute to further reducing the discrimination brought by the old Chinese terminology of AD laonian chidai. Development of formal services for elders with cognitive impairment may contribute to reducing caregivers' worries about future caregiving.

    This paper describes the characterisation of a new family of higher plant nuclear envelope-associated proteins (NEAPs) that interact with other proteins of the nuclear envelope. In the model plant Arabidopsis thaliana, the family consists of three genes expressed ubiquitously (AtNEAP1-3) and a pseudogene (AtNEAP4). NEAPs consist of extensive coiled-coil domains, followed by a nuclear localisation signal and a C-terminal predicted transmembrane domain. Domain deletion mutants confirm the presence of a functional nuclear localisation signal and transmembrane domain. AtNEAP proteins localise to the nuclear periphery as part of stable protein complexes, are able to form homo- and heteromers, and interact with the SUN domain proteins AtSUN1 and AtSUN2, involved in the linker of nucleoskeleton and cytoskeleton (LINC) complex. An A. thaliana cDNA library screen identified a putative transcription factor called AtbZIP18 as a novel interactor of AtNEAP1, which suggest a connection between NEAP and chromatin. An Atneap1 Atneap3 double-knockout mutant showed reduced root growth, and altered nuclear morphology and chromatin structure. Thus AtNEAPs are suggested as inner nuclear membrane-anchored coiled-coil proteins with roles in maintaining nuclear morphology and chromatin structure. © The Author 2016.

    2012-01-01

    The possibility that nuclear or other radioactive material could be used for malicious purposes cannot be ruled out in the current global situation. States have responded to this risk by engaging in a collective commitment to strengthen the protection and control of such material and to respond effectively to nuclear security events. States have agreed to strengthen existing instruments and have established new international legal instruments to enhance nuclear security worldwide. Nuclear security is fundamental in the management of nuclear technologies and in applications where nuclear or other radioactive material is used or transported. Through its Nuclear Security Programme, the IAEA supports States to establish, maintain and sustain an effective nuclear security regime. The IAEA has adopted a comprehensive approach to nuclear security. This recognizes that an effective national nuclear security regime builds on: the implementation of relevant international legal instruments; information protection; physical protection; material accounting and control; detection of and response to trafficking in such material; national response plans; and contingency measures. With its Nuclear Security Series, the IAEA aims to assist States in implementing and sustaining such a regime in a coherent and integrated manner. The IAEA Nuclear Security Series comprises Nuclear Security Fundamentals, which include objectives and essential elements of a State's nuclear security regime; Recommendations; Implementing Guides; and Technical Guidance. Each State carries the full responsibility for nuclear security, specifically: to provide for the security of nuclear and other radioactive material and associated facilities and activities; to ensure the security of such material in use, storage or in transport; to combat illicit trafficking and the inadvertent movement of such material; and to be prepared to respond to a nuclear security event.

    Tobacco use among Chinese adolescents is increasing at approximately 80,000 new smokers per day. Assessing the causes for initiating tobacco use in China will be important in developing effective interventions and policies to stem rising prevalence rates. This study tested predictors of Resilience Theory in a sample of 602 Chinese adolescents. Results revealed that prior adversity, measured through school and family-related events, was significantly associated with increased smoking in females. Family factors (i.e., family cohesion, family adaptability, parental monitoring) and one personal factor (i.e., academic score) were associated with lower odds for smoking due to prior adversity and negative disposition.

    Previous studies demonstrated that patients with different FBN1 mutations often present more considerable phenotypic variation compared to different members of the related family carrying a same mutation. The purpose of our study was to identify pathogenic mutation and provide more information about genotype-phenotypic correlations in a large Chinese family with Marfan syndrome. 15 related family members from a Chinese 4-generation pedigree with Marfan syndrome underwent physical, ophthalmologic, radiological and cardiovascular examinations. The propositus has De Bakey III aortic dissection and didn't fulfill the revised Ghent criteria for Marfan syndrome. Nine family members have ectopia lentis and their echocardiogram was normal. Five other family members have no evidence of Marfan syndrome. Genomic DNA was isolated from blood leukocytes. The exome sequencing was employed on the propositus, then the Sanger sequencing was conducted for mutation verification in other 14 participants of this family. The causative mutation in FBN1 discovered in the propositus was a known heterozygous missense mutation, c.1633T>G (p.R545C), in exon 14 (NM 000138). This same mutation was also identified in all 9 ectopia lentis patients and one unaffected 8-year-old girl. However, the same mutation was not discovered in other 4 unaffected family members. Our data enhance the information of genotype-phenotype correlation owing to FBN1 mutations. To our current knowledge, we firstly reported that the same FBN1 mutation, c. 1633C>T (Arg545Cys), was detected simultaneously in three different cardinal phenotypes (ectopia lentis, aortic dissection and unaffected) within one family. The unaffected girl with FBN1 mutation may presumably represent a rare case of nonpenetrance. Copyright © 2016 Elsevier B.V. All rights reserved.

    Amelogenesis imperfecta is a group of inherited diseases affecting the quality and quantity of dental enamel. To date, mutations in more than ten genes have been associated with non-syndromic amelogenesis imperfecta (AI). Among these, ENAM and LAMB3 mutations are known to be parts of the etiology of hypoplastic AI in human cases. When both alleles of LAMB3 are defective, it could cause junctional epidermolysis bullosa (JEB), while with only one mutant allele in the C-terminus of LAMB3, it could result in severe hypoplastic AI without skin fragility. We enrolled three Chinese families with hypoplastic autosomal-dominant AI. Despite the diagnosis falling into the same type, the characteristics of their enamel hypoplasia were different. Screening of ENAM and LAMB3 genes was performed by direct sequencing of genomic DNA from blood samples. Disease-causing mutations were identified and perfectly segregated with the enamel defects in three families: a 19-bp insertion mutation in the exon 7 of ENAM (c.406_407insTCAAAAAAGCCGACCACAA, p.K136Ifs*16) in Family 1, a single-base deletion mutation in the exon 5 of ENAM (c. 139delA, p. M47Cfs*11) in Family 2, and a LAMB3 nonsense mutation in the last exon (c.3466C>T, p.Q1156X) in Family 3. Our results suggest that heterozygous mutations in ENAM and LAMB3 genes can cause hypoplastic AI with markedly different phenotypes in Chinese patients. And these findings extend the mutation spectrum of both genes and can be used for mutation screening of AI in the Chinese population.

    Mutations in mitochondrial DNA (mtDNA) have been found to be associated with sensorineural hearing loss. We report here the clinical, genetic, and molecular characterization of four Chinese pedigrees with aminoglycoside-induced and nonsyndromic hearing impairment. Clinical evaluation revealed the variable phenotype of hearing impairment including audiometric configuration in these subjects, although these subjects share some common features: bilateral and sensorineural hearing impairment. Strikingly, these Chinese pedigrees exhibited extremely low penetrance of hearing loss (5.2%, 4.8%, 4.2%, and 13.3%, respectively, and with an average 8% penetrance). In particular, four of all five affected matrilineal relatives of these pedigrees had aminoglycoside-induced hearing loss. Sequence analysis of the complete mitochondrial genomes in these pedigrees showed the distinct sets of mtDNA polymorphism, in addition to the identical homoplasmic A1555G mutation, associated with hearing impairment in many families from different genetic backgrounds. The fact that mtDNA of those pedigrees belonged to different haplogroups R9a, N9a, D4a, and D4 suggested that the A1555G mutation occurred sporadically and multiplied through evolution of the mtDNA in China. However, there was the absence of functionally significant mutations in tRNA and rRNAs or secondary LHON mutations in these Chinese families. These data imply that the nuclear background or/and mitochondrial haplotype may not play a significant role in the phenotypic expression of the A1555G mutation in these Chinese pedigrees. However, aminoglycoside appears to be a major modifier factor for the phenotypic manifestation of the A1555G mutation in these Chinese families

    Members of the nuclear receptor (NR) superfamily of ligand-regulated transcription factors play important roles in reproduction, development, and physiology. In humans, genetic mutations in NRs are causes of rare diseases, while hormones and drugs that target NRs are in widespread therapeutic use. The present issue of the JCI includes a series of Review articles focused on specific NRs and their wide range of biological functions. Here I reflect on the past, present, and potential future highlights of research on the NR superfamily.

    Family factors are closely associated with child developmental outcomes. This study examined the relationship of oppositional defiant disorder (ODD) symptoms and factors at whole family, dyadic, and individual levels in Chinese children. Participants, who were recruited from 14 primary schools in north, east, and south-west China, included 80 father-child dyads and 169 mother-child dyads. Children in the participating dyads were previously diagnosed with ODD. Results revealed that family cohesion/adaptability was indirectly associated with ODD symptoms via parent-child relationship and child emotion regulation. Parent-child relationship affected ODD symptoms directly and indirectly through child emotion regulation. In addition, the effects of family cohesion/adaptability on parent emotion regulation and child emotion regulation were mediated by the parent-child relationship. The tested model provides a comprehensive framework of how family factors at multiple levels are related to child ODD symptoms and highlights the importance of understanding child emotional and behavioral problems within the family context, more specifically within the multiple levels of family relationships. © 2016 Family Process Institute.

    Full Text Available Both emphasising dilemmas that have been confronted by the Chinese-American family, Ang Lee’s The Wedding Banquet (1993 and Alice Wu’s Saving Face (2004 highlight the image of homosexuality as incompatible with traditional Chinese family values. Through detailed narrative analyses of these two films with a focus on the structure of the plot, the key characters, and camera work, this article aims to answer the questions of how traditional Chinese culture continues to play into and conflict with the experiences of modern Chinese American families and how each film presents and resolves the tensions arising from a culture in transition. The article argues that the importance of studying the ways in which the protagonists try to come to terms with incompatible value systems, lies in the capacity of film to reveal the complex negotiation between tradition and modernity, as well as the socio-cultural specificity of the conceptions of modernity.

    Autosomal dominant osteopetrosis type II (ADO-II) is a heritable bone disorder characterized by osteosclerosis, predominantly involving the spine (vertebral end-plate thickening, or rugger-jersey spine), the pelvis ("bone-within-bone" structures) and the skull base. Chloride channel 7 (CLCN7) has been reported to be the causative gene. In this study, we aimed to identify the pathogenic mutation in four Chinese families with ADO-II. All 25 exons of the CLCN7 gene, including the exon-intron boundaries, were amplified and sequenced directly in four probands from the Chinese families with ADO-II. The mutation site was then identified in other family members and 250 healthy controls. In family 1, a known missense mutation c.296A>G in exon 4 of CLCN7 was identified in the proband, resulting in a tyrosine (UAU) to cysteine (UGU) substitution at p.99 (Y99C); the mutation was also identified in his affected father. In family 2, a novel missense mutation c.865G>C in exon 10 was identified in the proband, resulting in a valine (GUC) to leucine (CUC) substitution at p.289 (V289L); the mutation was also identified in her healthy mother and sister. In family 3, a novel missense mutation c.1625C>T in exon 17 of CLCN7 was identified in the proband, resulting in an alanine (GCG) to valine (GUG) substitution at p.542 (A542V); the mutation was also identified in her father. In family 4, a hot spot, R767W (c.2299C>T, CGG>TGG), in exon 24 was found in the proband which once again proved the susceptibility of the site or the similar genetic background in different races. Moreover, two novel mutations, V289L and A542V, occurred at a highly conserved position, found by a comparison of the protein sequences from eight vertebrates, and were predicted to have a pathogenic effect by PolyPhen-2 software, which showed "probably damaging" with a score of approximately 1. These mutation sites were not identified in 250 healthy controls. Our present findings suggest that the novel missense

    Using a sample of 388 father–adolescent and 399 mother–adolescent dyads in Chinese immigrant families, the current investigation tested Portes and Rumbaut's (1996) assertion that generational dissonance may indicate a family context that places children at increased risk for adverse outcomes. Study findings suggest that a high discrepancy in father–adolescent acculturation levels relates significantly to more adolescent depressive symptoms. The study further demonstrates that the quality of the parenting relationship between fathers and adolescents operates as a mediator between father–adolescent acculturation discrepancy and adolescent depressive symptoms. Specifically, a high level of discrepancy in American orientation between fathers and adolescents is associated with unsupportive parenting practices, which, in turn, are linked to more adolescent depressive symptoms. These relationships are significant even after controlling for the influence of family socioeconomic status and parents’ and adolescents’ sense of discrimination within the larger society.

    Familial exudative vitreoretinopathy (FEVR) is a hereditary ocular disorder characterized by a failure of peripheral retinal vascularization. In this report, we describe a novel missense mutation of the Norrie disease gene (NDP) in a Chinese family with X-linked FEVR. Ophthalmologic evaluation was performed on four male patients and seven unaffected individuals after informed consent was obtained. Venous blood was collected from the 11 members of this family, and genomic DNA was extracted using standard methods. The coding exons 2 and 3 and their corresponding exon-intron junctions of NDP were amplified by polymerase chain reaction and then subjected to direct DNA sequencing. A novel missense mutation (c.310A>C) in exon 3, leading to a lysine-to-glutamine substitution at position 104 (p.Lys104Gln), was identified in all four patients with X-linked FEVR. Three unaffected female individuals (III2, IV3, and IV11) were found to be carriers of the mutation. This mutation was not detected in other unaffected individuals. The mutation c.310A>C (p.Lys104Gln) in exon 3 of NDP is associated with FEVR in the studied family. This result further enriches the mutation spectrum of FEVR. Copyright © 2016.

    The SQUAMOSA PROMOTER BINDING PROTEIN (SBP)-box gene family contains highly conserved plant-specific transcription factors that play an important role in plant development, especially in flowering. Chinese cabbage (Brassica rapa subsp. pekinensis) is a leafy vegetable grown worldwide and is used as a model crop for research in genome duplication. The present study aimed to characterize the SBP-box transcription factor genes in Chinese cabbage. Twenty-nine SBP-box genes were identified in the Chinese cabbage genome and classified into six groups. We identified 23 orthologous and 5 co-orthologous SBP-box gene pairs between Chinese cabbage and Arabidopsis. An interaction network among these genes was constructed. Sixteen SBP-box genes were expressed more abundantly in flowers than in other tissues, suggesting their involvement in flowering. We show that the MiR156/157 family members may regulate the coding regions or 3'-UTR regions of Chinese cabbage SBP-box genes. As SBP-box genes were found to potentially participate in some plant development pathways, quantitative real-time PCR analysis was performed and showed that Chinese cabbage SBP-box genes were also sensitive to the exogenous hormones methyl jasmonic acid and salicylic acid. The SBP-box genes have undergone gene duplication and loss, evolving a more refined regulation for diverse stimulation in plant tissues. Our comprehensive genome-wide analysis provides insights into the SBP-box gene family of Chinese cabbage.

    Study Objectives: To explore the familial aggregation and HLA susceptibility of narcolepsy in Hong Kong Chinese by objective sleep measurements and HLA typing. Design: Case control design Participants: Twelve narcoleptic probands, 34 first-degree relatives, and 30 healthy controls. Interventions: N/A Measurements and Results: Each subject underwent a standardized nocturnal polysomnogram (PSG), followed by a daytime multiple sleep latency test (MSLT). HLA typing was performed for all subjects. One relative (2.9%) was diagnosed as suffering from narcolepsy with cataplexy. Nearly 30% of the relatives fulfilled the criteria of narcolepsy spectrum disorder (shortened mean sleep latency [MSL] and/or the presence of sleep onset REM periods [SOREMPs]). When using the population data for comparison, the relative risk of narcolepsy in first-degree relatives was 85.3. The odds ratio of narcolepsy spectrum disorder in first-degree relatives was 5.8 (95% CI: 1.2 – 29.3) when compared to healthy controls. There existed 6 multiplex families, in which all 10 relatives with narcolepsy spectrum disorders, including all 3 relatives with multiple SOREMPs, were positive for HLA DQB1*0602. Conclusions: Our study demonstrated a definitive familial aggregation of narcolepsy, narcolepsy spectrum disorders, and possibly cataplexy in Hong Kong Chinese. This familial aggregation supported an inherited basis for narcolepsy spectrum. The tight co-segregation of HLA DQB1*0602 and narcolepsy spectrum disorders might suggest that HLA typing, especially DQB1*0602, at least partly confer the familial risk of narcolepsy. In addition, our study suggested that the subjective questionnaire measurements including Ullanlinna Narcolepsy Scale and Epworth Sleepiness Scale were unable to detect the presence of narcolepsy spectrum disorders among the relatives. A stringent objective measurement-based design for family studies is suggested for future study. Further studies are indicated for the determination

  3. Choosing a standard reactor: International competition and domestic politics in Chinese nuclear policy

    2011-01-01

    China has ambitious plans to expand its nuclear power capacity. One of the policy goals that high-level policymakers have desired is to base the nuclear program on a standardized reactor design. However, this has not materialized so far. By examining its nuclear reactor choices for individual projects, we argue that China’s policymaking process has been greatly influenced by international competition and domestic politics. Multiple international nuclear vendors are intent upon maintaining their respective niches in the expanding Chinese reactor market, and they have used various forms of economic and political pressure to achieve their objectives. On the other hand, China’s policymaking process is fragmented and the shifting power balances among powerful domestic actors do not allow a fixed path to be followed. Further, because of the high costs and potential profits involved, nuclear reactor choices in China have been driven not just by technical considerations but also by foreign and trade policy objectives. All of these make it unlikely that China will standardize the reactor type it constructs in the near future. -- Highlights: ► China’s nuclear power policymaking has been fragmented and without central control. ► Multiple domestic actors have pursued independent agendas. ► International nuclear vendors have intensely competed for Chinese reactor contracts. ► Economic, political and foreign policy goals have driven reactor contract decisions. ► China is unlikely to construct only a standardized reactor design.

    We report here the clinical, genetic, and molecular characterization of two Chinese families with aminoglycoside induced and non-syndromic hearing impairment. Clinical and genetic evaluations revealed the variable severity and age-of-onset in hearing impairment in these families. Strikingly, there were extremely low penetrances of hearing impairment in these Chinese families. Sequence analysis of the complete mitochondrial genomes in these pedigrees showed the distinct sets of mtDNA polymorphism, in addition to the identical G7444A mutation associated with hearing loss. Indeed, the G7444A mutation in the CO1 gene and the precursor of tRNA Ser(UCN) gene is present in homoplasmy only in the maternal lineage of those pedigrees but not other members of these families and 164 Chinese controls. Their mitochondrial genomes belong to the Eastern Asian haplogroups C5a and D4a, respectively. In fact, the occurrence of the G7444A mutation in these several genetically unrelated subjects affected by hearing impairment strongly indicates that this mutation is involved in the pathogenesis of hearing impairment. However, there was the absence of other functionally significant mtDNA mutations in two Chinese pedigrees carrying the G7444A mutation. Therefore, nuclear modifier gene(s) or aminoglycoside(s) may play a role in the phenotypic expression of the deafness-associated G7444A mutation in these Chinese pedigrees

    A complete set of neutron nuclear data for 54 important nuclides from H to 249 Cf has been evaluated and recommended, with the incident neutron energy range from 10 -5 eV to 20 MeV. The main features for CEDNDL-2 are as follows: on the basis of CENDL-1, was carried out the renewal evaluations, extended the energy region, supplemented the data type of evaluations, and added the new evaluations; established the computerized nuclear data library according to the international standard format; improved and developed the related theoretical methods and technology for nuclear data calculations and evaluation processing; developed a complete set of the theoretical calculation codes with new ideas and our own distinguishing features; and formed a complete set of programs for nuclear data processing and benchmark testing. With new experimental data, careful evaluation analysis and theoretical calculations, the evaluations for partial nuclides have our own distinguishing features to give significant improvement compared to the existing world-wide advanced nuclear data libraries. Some evaluations have been adopted by other advanced libraries. The CENDL-2 has been released as one of the five main advanced evaluated nuclear data libraries for users in the world by International Atomic Energy Agency

    Illicit trafficking of nuclear and other radioactive material has been an issue of concern since the first seizures in the early 1990s. By the end of 2004 Member States had confirmed 540 cases, while about another 500 remain unconfirmed. Most of the confirmed cases have a criminal dimension, even if they were not for known terrorist purposes. The attacks of September 2001 in the USA dramatically emphasized the requirement for the enhanced control and security of nuclear and other radioactive material. In response to a resolution by the IAEA General Conference in September 2002 the IAEA has adopted an integrated approach to protection against nuclear terrorism. This brings together IAEA activities concerned with the physical protection of nuclear material and nuclear installations, nuclear material accountancy, detection and response to illicit nuclear trafficking, the security and safety of radioactive sources, emergency response measures - including pre-emergency measures in Member States and at the IAEA - and the promotion of State adherence to relevant international instruments. States have the responsibility for combating illicit trafficking and the inadvertent movements of radioactive material. The IAEA cooperates with Member States and other international organizations in joint efforts to prevent incidents of illicit trafficking and inadvertent movements and to harmonize policies and measures by providing relevant advice through a range of technical assistance and documents. In this context, the IAEA issued a group of three technical documents, co-sponsored by the World Customs Organization, Europol and Interpol, on the inadvertent movement and illicit trafficking of radioactive material. The first is Prevention of the Inadvertent Movement and Illicit Trafficking of Radioactive Material (IAEA-TECDOC-1311), the second is called Detection of Radioactive Material at Borders (IAEA-TECDOC-1312) and the third is Response to Events Involving the Inadvertent Movement

    Hyperparathyroidism-jaw tumour syndrome (HPT-JT) and familial isolated primary hyperparathyroidism (FIHP) are two subtypes of familial primary hyperparathyroidism, which are rarely reported in Chinese population. Here, we reported three FIHP families and one HPT-JT family with long-term follow-up and genetic analysis. A total of 22 patients, from four FIHP/HPT-JT families of Chinese descent, were recruited and genomic DNA was extracted from their peripheral blood lymphocytes. Direct sequencing for MEN1, CDC73, CASR gene was conducted. Reverse transcription PCR (RT-PCR) and quantitative real-time PCR (qRT-PCR) were used to study the effect of splice site mutations and gross deletion mutations. Immunohistochemistry was performed to analyse parafibromin expression in parathyroid tumours. Genotype-phenotype correlations were assessed through clinical characteristics and long-term follow-up data. Genetic analysis revealed four CDC73 germline mutations that were responsible for the four kindreds, including two novel point mutation (c.157 G>T and IVS3+1 G>A), one recurrent point mutation (c.664 C>T) and one deletion mutation (c.307+?_513-?del exons 4, 5, 6). RT-PCR confirmed that IVS3+1 G>A generated an aberrant transcript with exon3 deletion. Immunohistochemical analysis demonstrated reduced nuclear parafibromin expression in tumours supporting the pathogenic effects of these mutations. This study supplies information on mutations and phenotypes of HPT-JT/FIHP syndrome in Chinese. Screening for gross deletion and point mutations of the CDC73 gene is necessary in susceptible subjects. © 2014 John Wiley & Sons Ltd.

    This study examined the antecedents of work-family conflict (WFC) and the mediation effects of WFC on well-being consequences among Chinese immigrants to New Zealand, along with the moderating role of acculturation. Four types of WFC were explored: time-based and strain-based work interference with family, and time-based and strain-based family interference with work. Data were collected from 577 Chinese immigrants in New Zealand, who had full-time or part-time work and lived with family members in New Zealand. The four types of WFC were differentially related to the antecedents and well-being consequences, providing some evidence that both Chinese and New Zealand cultures may exert influences on Chinese immigrants' experiences of WFC. Both directions of WFC (work interference with family, and family interference with work) were related to job satisfaction and family satisfaction, and strain-based WFC influenced their well-being more than time-based WFC. Most importantly, we found immigrants who were proficient in English perceived greater WFC and psychological strain. Copyright © 2016 John Wiley & Sons, Ltd. Copyright © 2016 John Wiley & Sons, Ltd.

    Full Text Available AIM: To make comprehensive molecular diagnosis for retinitis pigmentosa (RP patients in a consanguineous Han Chinese family using next generation sequencing based Capture-NGS screen technology. METHODS: A five-generation Han Chinese family diagnosed as non-syndromic X-linked recessive RP (XLRP was recruited, including four affected males, four obligate female carriers and eleven unaffected family members. Capture-NGS was performed using a custom designed capture panel covers 163 known retinal disease genes including 47 RP genes, followed by the validation of detected mutation using Sanger sequencing in all recruited family members. RESULTS: Capture-NGS in one affected 47-year-old male reveals a novel mutation, c.2417_2418insG:p.E806fs, in exon ORF15 of RP GTPase regulator (RPGR gene results in a frameshift change that results in a premature stop codon and a truncated protein product. The mutation was further validated in three of four affected males and two of four female carriers but not in the other unaffected family members. CONCLUSION: We have identified a novel mutation, c.2417_2418insG:p.E806fs, in a Han Chinese family with XLRP. Our findings expand the mutation spectrum of RPGR and the phenotypic spectrum of XLRP in Han Chinese families, and confirms Capture-NGS could be an effective and economic approach for the comprehensive molecular diagnosis of RP.

    Cystic fibrosis (CF) is the most common autosomal recessive disease among Caucasians but is rarer in the Chinese population, because mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene. To elucidate the causative role of a novel compound heterozygous mutation of CF. In this study, clinical samples were obtained from two siblings with recurrent airway infections, clubbed fingers, salt-sweat and failure to gain weight in a non-consanguineous Chinese family. Next-generation sequencing was performed on the 27 coding exons of CFTR in both children, with confirmation by Sanger sequencing. Next-generation sequencing showed the same compound heterozygous CFTR mutation (c.865A>T p.Arg289X and c.3651_3652insAAAT p.Tyr1219X) in both children. As this mutation is consistent with the clinical manifestations of CF and no other mutations were detected after scanning the gene sequence, we suggest that the CF phenotype is caused by compound heterozygosity for c.865A>T and c.3651_3652insAAAT. As c865A>T is not currently listed in the "Cystic Fibrosis Mutation Database", this information about CF in a Chinese population is of interest. © 2015 John Wiley & Sons Ltd.

    Parents' educational aspirations for youth play an important role in shaping youth's own educational aspirations; however, little is known about how and in what context parents may transmit their aspirations to youth effectively. This is of particular interest and import to be examined in Chinese families, given Chinese cultural emphasis on educational achievement and Chinese youth's outstanding academic performance internationally. By integrating several key theories of motivation and parental socialization (i.e., the expectancy-value model of academic achievement, the two-step model of value transmission, the contextual model of parenting, and the self-determination theory), the current study investigated simultaneously the mediating roles of parental involvement in youth's learning and youth's perceptions of parental aspirations, as well as the moderating role of parental warmth in the intergenerational transmission process of educational aspirations in Chinese families. A two-wave longitudinal study spanning about half a year was conducted among 323 Chinese seventh graders (54% female; M age  = 13.25 years) and one of their parents (median educational attainment = completion of high school, median monthly income = USD 766-1226). It was found that parental educational aspirations for youth were related positively both indirectly through parental involvement and directly to youth's perceptions of parental aspirations, which in turn were associated positively with youth's own educational aspirations about half a year later. It was also found that parental educational aspirations for youth and youth's own educational aspirations were associated positively with each other only when youth reported experiencing high levels of parental warmth, but unrelated when youth reported experiencing low levels of parental warmth, whereas such moderating effects of parental warmth were absent on the links from parental aspirations to youth's perceptions of parental

    Any quadratic system with limit cycles can be written in one of the three families stated by the Chinese classification. In this paper we consider family (I), i.e., x-bar =δx-y+-bar x2+mxy+ny2,y-bar =x. We show that the degree of its real irreducible invariant algebraic curves is bounded by 3. By the way, we prove that there is not any algebraic limit cycle for this family

    Full Text Available This paper aims to investigate the choice of governance modes in Chinese family firms. For that purpose, we build a principal-agent model to conduct our analyses. There are two modes of governance that the owner of the family firm can choose from, either the relational governance or the professional governance. The choice of governance modes is embodied in managerial compensation under different contractual arrangements. Our theoretical analyses show that under some conditions it is optimal for the owner to choose the relational governance, while under other conditions it is optimal for the owner to adopt the professional governance. That is to say, the choice of governance modes is condition-dependent

    2015-02-01

    A regional nuclear war between India and Pakistan could decrease global surface temperature by 1°C-2°C for 5-10 years and have major impacts on precipitation and solar radiation reaching Earth's surface. Using a crop simulation model forced by three global climate model simulations, we investigate the impacts on agricultural production in China, the largest grain producer in the world. In the first year after the regional nuclear war, a cooler, drier, and darker environment would reduce annual rice production by 30 megaton (Mt) (29%), maize production by 36 Mt (20%), and wheat production by 23 Mt (53%). With different agriculture management—no irrigation, auto irrigation, 200 kg/ha nitrogen fertilizer, and 10 days delayed planting date—simulated national crop production reduces 16%-26% for rice, 9%-20% for maize, and 32%-43% for wheat during 5 years after the nuclear war event. This reduction of food availability would continue, with gradually decreasing amplitude, for more than a decade. Assuming these impacts are indicative of those in other major grain producers, a nuclear war using much less than 1% of the current global arsenal could produce a global food crisis and put a billion people at risk of famine.

    Informed by Kohn and Schooler's (1969) occupational socialization framework, this study examined linkages between racial/ethnic minority mothers' perceptions of racial/ethnic discrimination in the workplace and adolescents' accounts of racial/ethnic socialization in the home. Data were collected from 100 mother-early adolescent dyads who participated in a longitudinal study of urban adolescents' development in the Northeastern United States, including African American, Latino, and Chinese families. Mothers and adolescents completed surveys separately. We found that when mothers reported more frequent institutional discrimination at work, adolescents reported more frequent preparation for bias messages at home, across racial/ethnic groups. Mothers' experiences of interpersonal prejudice at work were associated with more frequent cultural socialization messages among African American and Latino families. Chinese youth reported fewer cultural socialization messages when mothers perceived more frequent interpersonal prejudice at work. Findings are discussed in the context of minority groups' distinct social histories and economic status in the United States. (PsycINFO Database Record (c) 2014 APA, all rights reserved).

    2013-12-01

    For immigrant families, differential acculturation between mothers and fathers may present challenges to parenting adolescents. The current study investigated the concurrent relations among discrepancies in parental acculturation, discrepancies in parental expectations for adolescents, and coparenting quality with a sample of 162 married immigrant Chinese Canadian couples with adolescents (mean age = 14.94 years; SD = 1.73). Acculturation was assessed as parents' behavioral involvement in both Canadian and Chinese cultures. As predicted, mother-father differences in acculturation (in relation to both cultures) were related to discrepant expectations for how much adolescents should assist the family. Further, mother-father differences in Chinese acculturation were related to fathers' perceptions of a poorer coparenting relationship. Finally, this relation was partially mediated by discrepant parental expectations for adolescent assistance. Implications for parenting roles, enculturation, family dynamics, and intervention are considered.

    To provide an understanding of Chinese new mothers' breastfeeding behaviors and especially to explore the relationship between the mothers perceived family perception about breastfeeding and the new mothers' breastfeeding behaviors. A cross-sectional questionnaire survey was conducted in Beijing and Yinchuan, the capital of Ning Xia Province, China. 214 new mothers with a baby at the age of 4 months were recruited to the study. The family perception of breastfeeding scale and the new mothers' breastfeeding behavior record were used. The response rate was n=200, 94%. Most of the new mothers perceived positive family perceptions about breastfeeding with an average score of 23.13 using the family perception of breastfeeding scale. Nearly half of the respondents reported that they exclusively breastfed their infants (n=94, 47%). The main reason for breastfeeding difficulty was inadequate lactation (n=56, 69%). The new mothers who breastfed their infants mentioned significantly stronger family perceptions/support compared to those who used mixed feeding or artificial feeding (p0.05) in the types of mothers' feeding behaviors across the different age group, occupation, ethnicity, educational level, mode of delivery, the time of the baby's first suck, bottle feeding before the baby's first suck and the time of having colostrums. It is suggested to develop some strategies, such as family-centered antenatal and postnatal education programmes, to increase the rate of exclusive breastfeeding by influencing new mothers' families about breastfeeding. Further research is needed to explore socio-demographic variables associated with new-mothers' breastfeeding behaviors. Copyright © 2011 Elsevier B.V. All rights reserved.

    Full Text Available This study aimed to 1 examine relationships between uncertainty, perceived information, personal values, social support, and filial obligation among Chinese family caregivers faced with nursing home placement of an older adult family member with dementia; and 2 describe the applicability of the Decisional Conflict Scale in nursing home placement decision making among Chinese family caregivers through the integration of quantitative and qualitative data. We used a mixed-methods approach. Quantitative data analysis consisted of descriptive and correlational statistics. We utilized a thematic analysis for the qualitative data. Data transformation and data comparison techniques were used to combine qualitative and quantitative data. Thirty Chinese family caregivers living in Taiwan caring for an older adult with dementia participated in this study. We found a significant association among the quantitative findings, which indicated that perceived information, personal values, social support, and filial obligation, and nursing home placement decisional conflict. Mixed-method data analysis additionally revealed that conflicting differences existed between the traditional role of Chinese family collective decision making and the contemporary role of single family member surrogate decision making. Although the Decisional Conflict Scale can be utilized when exploring nursing home placement for an older adult with dementia among Chinese family caregivers, applicability issues existed regarding cultural beliefs and values related to filial piety and family collectivism. Findings strongly support the need for researchers to consider cultural beliefs and values when selecting tools that assess health-related decision making across cultures. Further research is needed to explore the role culture plays in nursing home decision making.

    The penetrance of Leber's hereditary optic neuropathy (LHON) in families with primary mitochondrial DNA (mtDNA) mutations is very complex. Matrilineal and nuclear genetic background, as well as environmental factors, have been reported to be involved in different affected pedigrees. Here we describe two large Chinese families that show a striking difference in the penetrance of LHON, in which 53.3% and 15.0% of members were affected (P < 0.02), respectively. Analysis of the complete mtDNA genome of the two families revealed the presence of the primary mutation G11778A and several other variants suggesting the same haplogroup status G2a. The family with higher penetrance contained a previously described secondary mutation G13708A, which presents a polymorphism in normal Chinese samples and does not affect in vivo mitochondrial oxidative metabolism as described in a previous study. Evolutionary analysis failed to indicate any putatively pathogenic mutation that cosegregated with G11778A in these two pedigrees. Our results suggest that the variable penetrance of LHON in the two Chinese families is independent of both their mtDNA haplotype background and a secondary mutation G13708A. As a result, it is likely that unknown nuclear gene involvement and/or other factors contribute to the strikingly different penetrance of LHON

    Chinese secondary school students (N = 365) responded to instruments measuring their family environment, psychological well-being, school adjustment, and problem behavior. Measures of the family environment include perceived paternal and maternal parenting styles, family functioning, and conflict with father and mother. Results from bivariate and canonical correlation analyses showed that in general, adolescents' perceptions of parenting styles, family functioning, and parent-adolescent conflict were significantly related to scores on measures of psychological well-being (general psychiatric morbidity, life satisfaction, purpose in life, hopelessness, and self-esteem), school adjustment (perceived academic performance and school conduct), and problem behavior (smoking and psychotropic drug abuse). The findings suggest that family factors play an important role in influencing the psychosocial adjustment, particularly the positive mental health, of Chinese adolescents.

  7. Estimating Heritability from Nuclear Family and Pedigree Data.

    Heritability is a measure of familial resemblance. Estimating the heritability of a trait could be one of the first steps in the gene mapping process. This chapter describes how to estimate heritability for quantitative traits from nuclear and pedigree data using the ASSOC program in the Statistical Analysis in Genetic Epidemiology (S.A.G.E.) software package. Estimating heritability rests on the assumption that the total phenotypic variance of a quantitative trait can be partitioned into independent genetic and environmental components. In turn, the genetic variance can be divided into an additive (polygenic) genetic variance, a dominance variance (nonlinear interaction effects between alleles at the same locus) and an epistatic variance (interaction effects between alleles at different loci). The last two are often assumed to be zero. The additive genetic variance represents the average effects of individual alleles on the phenotype and reflects transmissible resemblance between relatives. Heritability in the narrow sense (h 2 ) refers to the ratio of the additive genetic variance to the total phenotypic variance. Heritability is a dimensionless population-specific parameter. ASSOC estimates association parameters (regression coefficients) and variance components from family data. ASSOC uses a linear regression model in which the total residual variance is partitioned, after regressing on covariates, into the sum of random components such as an additive polygenic component, a random sibship component, random nuclear family components, a random marital component, and an individual-specific random component. Assortative mating, nonrandom ascertainment of families, and failure to account for key confounding factors may bias heritability estimates.

    The molecular characterization of 34 members of a Chinese family, with 22 members in four generations, affected with Waardenburg syndrome (WS1). A detailed family history and clinical data were collected. A genome-wide scan by two-point linkage analysis using more than 400 microsatellite markers in combination with haplotype analysis was performed. Mutation screening was carried out in the candidate gene by sequencing of amplified products. A maximum two-point lod score of 6.53 at theta = 0.00 was obtained with marker D2S2248. Haplotype analysis placed the WS1 locus to a 45.74 cM region between D2S117 and D2S206, in close proximity to the PAX3 gene on chromosome 2q35. Mutation screening in PAX3 identified a 701T > C mutation which converted a highly conserved Leu to Pro. This nucleotide alteration was neither seen in unaffected members of the family nor found in 50 unrelated control subjects. The present study identified a novel 701T > C mutation in PAX3. The mutation observed in this family highlights the phenotypic heterogeneity of the disorder.

    To investigate the disease-causing mutation in a Chinese family affected with Usher syndrome type II. All of the 11 members from the family underwent comprehensive ophthalmologic examination and hearing test, and their genomic DNA were isolated from venous leukocytes. PCR and direct sequencing of USH2A gene were performed for the proband. Wild type and mutant type minigene vectors containing exon 42, intron 42 and exon 43 of the USH2A gene were constructed and transfected into Hela cells by lipofectamine reagent. Reverse transcription (RT)-PCR was carried out to verify the splicing of the minigenes. Pedigree analysis and clinical diagnosis indicated that the patients have suffered from autosomal recessive Usher syndrome type II. DNA sequencing has detected a homozygous c.8559-2A>G mutation of the USH2A gene in the proband, which has co-segregated with the disease in the family. The mutation has affected a conserved splice site in intron 42, which has led to inactivation of the splice site. Minigene experiment has confirmed the retaining of intron 42 in mature mRNA. The c.8559-2A>G mutation in the USH2A gene probably underlies the Usher syndrome type II in this family. The splice site mutation has resulted in abnormal splicing of USH2A pre-mRNA.

    Little is known about the influence of parent-adolescent relationships and peer behavior on emotional distress and risky behaviors among Asian American adolescents; in particular, cross-cultural and longitudinal examinations are missing from the extant research. To test and compare a theoretical model examining the influence of family and peer factors on adolescent distress and risky behavior over time, using a nationally representative sample of Chinese, Filipino, and White adolescents. Data were utilized from Waves I (1994) and II (1995) of the National Longitudinal Study on Adolescent Health; the sample is composed of 194 Chinese, 345 Filipino, and 395 White adolescents and weighted to correct for design effects, yielding a nationally representative sample. Structural equation modeling was used to test the theoretical model for each ethnic group separately followed by multiple-group analyses. The measurement model was examined for each ethnic group, using both unweighted and weighted samples, and was deemed equivalent across groups. Tests of the theoretical model by ethnicity revealed that for each group, family bonds have significant negative effects on emotional distress and risky behaviors. For Filipino and White youth, peer risky behaviors influenced risky behaviors. Multiple-group analyses of the theoretical model indicated that the three ethnic groups did not differ significantly from one another. Findings suggest that family bonds and peer behavior exert significant influences on psychological and behavioral outcomes in Asian American youth and that these influences appear to be similar with White adolescents. Future research should be directed toward incorporating variables known to contribute to the impact of distress and risky behaviors in model testing and validating findings from this study.

    Population-based studies have reported high rates of smoking prevalence among Chinese and Vietnamese American men. Although nicotine replacement therapy (NRT) is effective, recommended, and accessible without prescription, these populations underuse NRT for smoking cessation. The aim of this study was to assess understanding and use of NRT and nonpharmacologic treatments among Chinese and Vietnamese American male smokers and their families. In-depth qualitative interviews were conducted with 13 smoker-family pairs, followed by individual interviews with each participant. A total of 39 interviews were conducted in Vietnamese or Chinese, recorded, translated, and transcribed into English for analysis. Four themes were identified: use and understanding of NRT, nonpharmacologic strategies, familial and religious approaches, and willpower. Both smokers and their family members believed strongly in willpower and a sense of personal responsibility as the primary drivers for stopping smoking. Lack of these 2 qualities keeps many Chinese and Vietnamese men from using NRT to quit smoking. Those who do use NRT often use it incorrectly, following their own preferences rather than product instructions. Our findings indicate the importance of culturally appropriate patient education about NRT. It may be necessary to teach smokers and their families at an individual level about NRT as a complementary approach that can strengthen their resolve to quit smoking. At a community level, public health education on the indication and appropriate use of evidence-based smoking cessation resources, such as NRT, would be an important component of effective tobacco control.

    To explore the coping strategies of Chinese family caregivers of stroke-impaired older relatives. Many stroke-impaired patients rely heavily on support from their families, and the daily lives of such family caregivers are severely impacted. However, services and support for family caregivers of stroke-impaired relatives in the home setting have received little attention. Appropriate and relevant information and support to family caregivers are important in facilitating the care-giving task. It is, therefore, necessary to understand the nature and demands of care-giving before planning specific educational and support programmes. Grounded theory. Fifteen Chinese family caregivers of stroke-impaired older relatives were recruited and interviewed in 2003 and 2004. Theoretical sampling and constant comparative analysis were used to recruit the sample and perform data analysis. Seeking harmony to provide care for the stroke-impaired was the core category for describing and guiding the family care-giving process, with five main stages: (1) living with ambiguity, (2) monitoring the recovery progress, (3) accepting the downfalls, (4) meeting family obligations and (5) reconciling with harmony. These issues were seldom discussed openly with health professionals. The findings indicated that Chinese family caregivers determine their own needs by seeking harmony to continue to provide care without thinking about getting help from others or their own health problems. These findings help to define some of the complex dynamics that have an impact on the development of partnership care and might challenge nurses practising in the community. Community nurses should assess and understand the coping strategies of family caregivers and assist them to engage in stress-reducing practices. This is an important partnership to be formed in stroke care for family caregivers in the community. The study findings will guide further development of family care-giving aspects in nursing practice

    Full Text Available AIM: To investigate the genetic mutations that are associated the hereditary autosomal dominant cataract in a Chinese family. METHODS: A Chinese family consisting of 20 cataract patients (including 9 male and 11 female and 2 unaffected individuals from 5 generations were diagnosed to be a typical autosomal dominant cataract pedigree. Genomic DNA samples were extracted from the peripheral blood cells of the participants in this pedigree. Exon sequence was used for genetic mutation screening. In silico analysis was used to study the structure characteristics of connexin 46 (CX46 mutant. Immunoblotting was conduceted for testing the expression of CX46. RESULTS: To determine the involved genetic mutations, 11 well-known cataract-associated genes (cryaa, cryab, crybb1, crybb2, crygc, crygd, Gja3, Gja8, Hsf4, Mip and Pitx3 were chosen for genetic mutation test by using exon sequencing. A novel cytosine insertion at position 1195 of CX46 cDNA (c.1194_1195ins C was found in the samples of 5 tested cataract patients but not in the unaffected 2 individuals nor in normal controls, which resulted in 30 amino acids more extension in CX46C-terminus (cx46fs400 compared with the wild-type CX46. In silico protein structure analysis indicated that the mutant showed distinctive hydrophobicity and protein secondary structure compared with the wild-type CX46. The immunoblot results revealed that CX46 protein, which expressed in the aging cataract lens tissues, was absence in the proband lens. In contrast, CX50, alpha A-crystallin and alphaB-crystallin expressed equally in both proband and aging cataract tissues. Those results revealed that the cx46fs400 mutation could impair CX46 protein expression. CONCLUSION: The insertion of cytosine at position 1195 of CX46 cDNA is a novel mutation site that is associated with the autosomal dominant cataracts in this Chinese family. The C-terminal frameshift mutation is involved in regulating CX46 protein expression.

    To identiy the disease causing mutation in a Chinese family presenting with early-onset cataract and dental anomalies. A specific Hereditary Eye Disease Enrichment Panel (HEDEP) (personalized customization by MyGenostics, Baltimore, MD) based on targeted exome capture technology was used to collect the protein coding regions of 30 early-onset cataract associated genes, and high throughput sequencing was done with Illumina HiSeq 2000 platform. The identified variant was confirmed with Sanger sequencing. A novel deletion in exon 4 (c.852delG) of NHS gene was identified; the identified 1 bp deletion altered the reading frame and was predicted to result in a premature stop codon after the addition of twelve novel amino acid (p.S285PfsX13). This mutation co-segregated in affected males and obligate female carriers, but was absent in 100 matched controls. Our findings broaden the spectrum of NHS mutations causing Nance-Horan syndrome and phenotypic spectrum of the disease in Chinese patients.

    Benevolent leadership, a traditional Chinese leadership style generated under the influence of Confucianism, has been under growing discussion since its proposal. However, existing research has focused mainly on the consequences of benevolent leadership, and research probing into its antecedents is scarce. To fill such research gap, the current study aims to explore the effect of the congruence between implicit positive followership prototype (PFP) and explicit positive followership trait (PFT) on benevolent leadership. Polynomial regression combined with the response surface methodology was used to test the hypotheses herein. The results, based on a sample of 241 leader-follower dyads from four Chinese family firms, indicated the following: (1) benevolent leadership is higher when leader PFP is congruent with follower PFT than when they are incongruent; (2) in cases of congruence, benevolent leadership is higher when leader PFP and follower PFT are both high rather than low; (3) in the case of incongruence, there is no significant difference for the level of benevolent leadership in two scenarios: "low leader PFP - high follower PFT" and "high leader PFP - low follower PFT".

    Scholars traditionally argued that industrialization, urbanization, and educational expansion lead to a decline in extended families and complementary rise in nuclear families. Some have suggested that such transitions are good for young married women because living in nuclear families benefits their health. However, extended families may also present advantages for young women's health that outweigh any disadvantages. Using the Indian National Family Health Survey, this article examines whether young married women living in nuclear families have better health than those in patrilocal extended families. It also examines whether young married women's living arrangements are changing over time and, if so, how such changes will affect their health. Results show that young married women living in nuclear families do not have better health than those in patrilocal extended families. Of eight health outcomes examined, only five differ significantly by family structure. Further, of the five outcomes that differ, four are patrilocal extended-family advantages and only one is a nuclear-family advantage. From 1992 to 2006, the percentage of young married women residing in nuclear families increased, although the majority remained in patrilocal extended families. This trend toward nuclear families will not benefit young women's health.

    Corneal transplantation is the treatment of choice for many corneal diseases. At present, there is a global shortage of corneal transplant tissues, and failure to obtain consent from families of potential donors is a major limiting factor in tissue procurement. All family members of potential donors after cardiac death approached by the local eye bank staff members from January 2008 to December 2014 in Hong Kong were included. Reasons for consent or refusal and sociodemographic details of the deceased and the family members approached were reviewed. Trends in consent rates from 2008 to 2014 were examined. Multivariable logistic regression was performed to examine determinants of donation among cases from 2013 to 2014. A total of 1740 cases were identified. The overall consent rate was 36.8%, and the consent rate did not change significantly over the 7-year study period (P = 0.24). The most common reason for consent by family members was "the wish to help others" (86.0%), and the most common reason for refusal was "traditional Chinese culture to keep the body intact after death" (42.7%). From the multivariable analysis in the subset of cases from 2013 to 2014 (n = 628), family members were more likely to consent when the deceased was female (adjusted odds ratio 1.45, P = 0.03), with a do-not-resuscitate order (adjusted odds ratio 2.27, P < 0.001). The consent rate for eye donation did not change significantly from 2008 to 2014. Our findings suggest that health education and promotion campaigns need to address cultural barriers to organ donation.

    The aim of this study was to identify mutations of CHST6 gene in a Chinese family with macular corneal dystrophy (MCD) and to investigate the histopathological changes of MCD. Corneal button of the proband was obtained from penetrating keratoplasty for the treatment of severe corneal dystrophy. The sections and ultrathin sections of this specimen were examined under light microscope and transmission electron microscope (TEM). Genomic DNA was extracted from leukocytes in peripheral blood from the family members. The coding region of CHST6 was amplified by polymerase chain reaction (PCR). The PCR products were analyzed by direct sequencing and restriction enzyme digestion. Histochemical study revealed positive results of colloidal iron stain. TEM revealed enlargement of smooth endoplasmic reticulum and the presence of intracytoplasmic vacuoles. Two mutations, Q298X Y358H, were identified in exon 3 of CHST6. Three patients were compound heterozygotes of these two mutations. The C892T transversion occurred at codon 298 turned the codon of glutamine to a stop codon; the T1072C transversion occurred at codon 358 caused a missense mutation, tyrosine to histidine. All six unaffected family members were heterozygotes. These two mutations were not detected in any of the 100 control subjects. The novel compound heterozygous mutation results in loss of CHST6 function and causes the occurrence of MCD. This is the first report of this gene mutation.

    Nance-Horan Syndrome (NHS) (OMIM: 302350) is a rare X-linked developmental disorder characterized by bilateral congenital cataracts, with occasional dental anomalies, characteristic dysmorphic features, brachymetacarpia and mental retardation. Carrier females exhibit similar manifestations that are less severe than in affected males. Here, we report a four-generation Chinese family with multiple affected individuals presenting Nance-Horan Syndrome. Whole-exome sequencing combined with RT-PCR and Sanger sequencing was used to search for a genetic cause underlying the disease phenotype. Whole-exome sequencing identified in all affected individuals of the family a novel donor splicing site mutation (NM_198270: c.1045 + 2T > A) in intron 4 of the gene NHS, which maps to chromosome Xp22.13. The identified mutation results in an RNA processing defect causing a 416-nucleotide addition to exon 4 of the mRNA transcript, likely producing a truncated NHS protein. The donor splicing site mutation NM_198270: c.1045 + 2T > A of the NHS gene is the causative mutation in this Nance-Horan Syndrome family. This research broadens the spectrum of NHS gene mutations, contributing to our understanding of the molecular genetics of NHS.

    Usher syndrome (USH) is the most common cause of combined blindness and deafness inherited in an autosomal recessive mode. Molecular diagnosis is of great significance in revealing the molecular pathogenesis and aiding the clinical diagnosis of this disease. However, molecular diagnosis remains a challenge due to high phenotypic and genetic heterogeneity in USH. This study explored an approach for detecting disease-causing genetic mutations in candidate genes in five index cases from unrelated USH families based on targeted next-generation sequencing (NGS) technology. Through systematic data analysis using an established bioinformatics pipeline and segregation analysis, 10 pathogenic mutations in the USH disease genes were identified in the five USH families. Six of these mutations were novel: c.4398G > A and EX38-49del in MYO7A, c.988_989delAT in USH1C, c.15104_15105delCA and c.6875_6876insG in USH2A. All novel variations segregated with the disease phenotypes in their respective families and were absent from ethnically matched control individuals. This study expanded the mutation spectrum of USH and revealed the genotype-phenotype relationships of the novel USH mutations in Chinese patients. Moreover, this study proved that targeted NGS is an accurate and effective method for detecting genetic mutations related to USH. The identification of pathogenic mutations is of great significance for elucidating the underlying pathophysiology of USH.

    International Nuclear Information System (INIS)

    2014-01-01

    The possibility that nuclear material or other radioactive material could be used for criminal purposes or intentionally used in an unauthorized manner cannot be ruled out in the current global situation. States have responded to this risk by engaging in a collective commitment to strengthen the protection and control of such material and to respond effectively to nuclear security events. States have agreed to strengthen existing instruments and have established new international legal instruments to enhance nuclear security worldwide. Nuclear security is fundamental in the management of nuclear technologies and in applications where nuclear material or other radioactive material is used or transported. Through its nuclear security programme, the IAEA supports States to establish, maintain and sustain an effective nuclear security regime. The IAEA has adopted a comprehensive approach to nuclear security. This recognizes that an effective national nuclear security regime builds on: the implementation of relevant international legal instruments; information protection; physical protection; material accounting and control; detection of and response to trafficking in such material; national response plans; and contingency measures. With its Nuclear Security Series, the IAEA aims to assist States in implementing and sustaining such a regime in a coherent and integrated manner. The IAEA Nuclear Security Series comprises: Nuclear Security Fundamentals, which include the objective and essential elements of a State's nuclear security regime; Recommendations; Implementing Guides; and Technical Guidance. Each State carries the full responsibility for nuclear security. Specifically, each State has the responsibility to provide for the security of nuclear material and other radioactive material and their associated facilities and activities; to ensure the security of such material in use, storage, or in transport; to combat illicit trafficking and the inadvertent movement of

    Research on ethnic minority parenting has examined heritage cultural influences and contextual stressors on parenting processes. However, rarely are adaptive cultural processes considered, whereby ethnic minority parents bring their cultural values to bear in adapting to contextual demands in the host society. A survey of 107 Chinese American immigrant parents examined whether use of physical discipline can be predicted by cultural values, contextual stressors, and their interactions. Results indicated that distinct domains of cultural values were related to physical discipline in disparate ways, with some values decreasing risk and others indirectly increasing risk. There was some evidence that cultural values interacted with contextual stress to predict physical discipline. Parent-child acculturation conflicts were only related to physical discipline when parents held strong values about the importance of firm parental control. The findings illustrate how heritage cultural influences and current ecological demands may converge to shape parenting in immigrant families.

    This longitudinal study examined the influence of parents’ educational attitudes on adolescents’ educational attitudes and identified antecedents (i.e., parent education, family income, and parent acculturation), consequences (i.e., academic achievement and engagement), and a potential moderator (i.e., adolescent acculturation) of the transmission process. The sample was 444 Chinese American mothers, fathers, and adolescents (12–15 at W1). Using path analysis, this study found significant two-way interactions among parent education, income, and acculturation in predicting parents’ concurrent positive educational attitudes, which, in turn, predicted adolescents’ attitudes at W2. The latter link was further moderated by W1 and W2 adolescent acculturation for mother-adolescent and father-adolescent dyads. Adolescents’ positive educational attitudes at W2, in turn, were positively associated with their concurrent academic achievement and engagement. PMID:27138812

    This paper provides evidence to show that in the presence of imperfect formal institutions there is both a substitutional and a complementary relationship between accounting information and reputation, an informal institution. Empirical results using a sample of family firms listed in the Chinese A-share stock market from 2004 to 2007 show that in China, where the legal environment is far from perfect, the complementary relationship between reputation and accounting information is more pronounced than is the substitutional relationship. Thus, the aggregate effect is that a better reputation improves the usefulness of accounting information in debt contracts. Besides the aggregate effect, this paper also provides evidence of the substitutional and complementary relationships between reputation and accounting separately.

    2011-01-01

    Full Text Available The escalating youth drug abuse problem in Hong Kong has attracted intense attention from the government, schools, and youth service professionals. Most preventive efforts have focused directly on positive youth development, very often through school programs delivered to secondary school students. There have been limited efforts to engage parents even though it is obvious that the family is actually the primary context of children and youth development. This paper will assert the importance of parental engagement in youth drug-prevention work, discuss some barriers in such parental involvement, present some promising local attempts and their strengths and limitations, and propose that sustained efforts are needed to build up theory-driven and evidence-based resources for Chinese communities on the subject.

    We report here the clinical, genetic, and molecular characterization of two Chinese pedigrees with aminoglycoside-induced and non-syndromic hearing impairment. Clinical evaluation revealed the variable phenotype of hearing impairment including audiometric configuration in these subjects. Penetrances of hearing loss in BJ105 and BJ106 pedigrees are 67% and 33%, respectively. In particular, three of 10 affected matrilineal relatives of BJ105 pedigree had aminoglycoside-induced hearing loss, while seven affected matrilineal relatives in BJ105 pedigree and six affected matrilineal relatives in BJ106 pedigree did not have a history of exposure to aminoglycosides. Sequence analysis of the complete mitochondrial genomes in these pedigrees showed the identical homoplasmic A1555G mutation and distinct sets of mtDNA variants belonging to haplogroups F3 and M7b. These variants showed no evolutionary conservation, implying that mitochondrial haplotype may not play a significant role in the phenotypic expression of the A1555G mutation in these Chinese pedigrees. However, aminoglycosides and nuclear backgrounds appear to be major modifier factors for the phenotypic manifestation of the A1555G mutation in these Chinese families

    Purpose Seven genes involved in precursor mRNA (pre-mRNA) splicing have been implicated in autosomal dominant retinitis pigmentosa (adRP). We sought to detect mutations in all seven genes in Chinese families with RP, to characterize the relevant phenotypes, and to evaluate the prevalence of mutations in splicing genes in patients with adRP. Methods Six unrelated families from our adRP cohort (42 families) and two additional families with RP with uncertain inheritance mode were clinically characterized in the present study. Targeted sequence capture with next-generation massively parallel sequencing (NGS) was performed to screen mutations in 189 genes including all seven pre-mRNA splicing genes associated with adRP. Variants detected with NGS were filtered with bioinformatics analyses, validated with Sanger sequencing, and prioritized with pathogenicity analysis. Results Mutations in pre-mRNA splicing genes were identified in three individual families including one novel frameshift mutation in PRPF31 (p.Leu366fs*1) and two known mutations in SNRNP200 (p.Arg681His and p.Ser1087Leu). The patients carrying SNRNP200 p.R681H showed rapid disease progression, and the family carrying p.S1087L presented earlier onset ages and more severe phenotypes compared to another previously reported family with p.S1087L. In five other families, we identified mutations in other RP-related genes, including RP1 p. Ser781* (novel), RP2 p.Gln65* (novel) and p.Ile137del (novel), IMPDH1 p.Asp311Asn (recurrent), and RHO p.Pro347Leu (recurrent). Conclusions Mutations in splicing genes identified in the present and our previous study account for 9.5% in our adRP cohort, indicating the important role of pre-mRNA splicing deficiency in the etiology of adRP. Mutations in the same splicing gene, or even the same mutation, could correlate with different phenotypic severities, complicating the genotype–phenotype correlation and clinical prognosis.

    Full Text Available BACKGROUND: The WNT1-inducible signaling pathway protein 3 (WISP3, which belongs to the CCN (cysteine-rich protein 61, connective tissue growth factor, nephroblastoma overexpressed family, is a secreted cysteine-rich matricellular protein that is involved in chondrogenesis, osteogenesis and tumorigenesis. WISP3 gene mutations are associated with progressive pseudorheumatoid dysplasia (PPD, OMIM208230, an autosomal recessive genetic disease that is characterized by the swelling of multiple joints and disproportionate dwarfism. METHODOLOGY/PRINCIPAL FINDINGS: Four PPD patients from two unrelated Chinese families were recruited for this study. The clinical diagnosis was confirmed by medical history, physical examinations, laboratory results and radiological abnormalities. WISP3 mutations were detected by direct DNA sequence analysis. In total, four different mutations were identified, which consisted of two missense mutations, one deletion and one insertion that spanned exons 3, 5 and 6 of the WISP3 gene. One of the missense mutations (c.342T>G/p.C114W and a seven-base pair frameshift deletion (c.716_722del/p.E239fs*16 were novel. The other missense mutation (c.1000T>C/p. S334P and the insertion mutation (c.866_867insA/p.Q289fs*31 had previously been identified in Chinese patients. All four cases had a compound heterozygous status, and their parents were heterozygous carriers of these mutations. CONCLUSIONS/SIGNIFICANCE: The results of our study expand the spectrum of WISP3 mutations that are associated with PPD and further elucidate the function of WISP3.

    Nuclear receptors (NRs) rely on coregulators (coactivators and corepressors) to modulate the transcription of target genes. By interacting with nucleosome remodeling complexes, NR coactivators potentiate transcription, whereas corepressors inhibit transcription of the target genes. Metastasis-associated proteins (MTA) represent an emerging family of novel NR coregulators. In general, MTA family members form independent nucleosome remodeling and deacetylation (NuRD) complexes and repress the transcription of different genes by recruiting histone deacetylases onto their target genes. However, MTA1 also acts as a coactivator in a promoter-context dependent manner. Recent findings that repression of estrogen receptor transactivation functions by MTA1, MTA1s, and MTA2 and regulation of MTA3 by estrogen signaling have indicated the significance of these proteins in NR signaling. Here, we highlight the action of MTA proteins on NR signaling and their roles in pathophysiological conditions. PMID:18174918

    Full Text Available Background: Low job satisfaction is the most common cause of nurses' turnover and influences the quality of nursing service. Moreover, we have no idea regarding whether job control, as an individual factor, can play a role in the relationship. Objective: To explore the relationship between work-family conflict and job satisfaction among Chinese registered nurses and the mediating role of job control in this relationship. Methods: From August 2015 to November 2016, 487 Chinese registered nurses completed a survey. The study used work-family conflict scale, job control scale, job satisfaction scale, as well as general information. Multiple regression analysis was used to explore the independent factors of job satisfaction. Structural equation model was used to explore the mediating role of job control. Results: Work-family conflict was negatively correlated with job satisfaction (r ‑0.432, p<0.01. In addition, job control was positively related to job satisfaction (r 0.567, p<0.01. Work-family conflict and job control had significant predictive effects on job satisfaction. Job control partially mediated the relationship between work-family conflict and job satisfaction. Conclusion: Work-family conflict affected job satisfaction and job control was a mediator in this relationship among Chinese registered nurses. Job control could potentially improve nurses' job satisfaction.

    In order to protect aquatic life from the harmful effects of thermal discharge, the appropriate water temperature limits or the scope of the mixing zone is a key issue in the regulatory control of the environmental impact of thermal discharge. Based on the sea surface temperature in the Chinese coastal waters, the extreme value of the seawater temperature change was analyzed by using the Gumbel model. The limit of the design temperature rise of cooling water in the outfall is 9 ℃, and the limit of the temperature rise of cooling water in the edge of the mixing zone is 4 ℃. The extreme high temperature of the cooling water in Chinese coastal nuclear power plant is 37 ℃ in the Bohai Sea, Yellow Sea, and is 40 ℃ in East China Sea, South China Sea. (authors)

    To understand the prevalence of passive smoking in Chinese families and discuss its associated factors, as to providing scientific evidence for establishing tobacco control measures in China. Cross-sectional survey: from June to September, 2004, we randomly selected six counties in three different provinces ( Mianzhu and Xichong of Sichuan Province; Anyi and Hukou of Jiangxi Province; Xinan and Yanshi of Henan Province) and performed face-to-face questionnaire survey on citizens between 18 and 69 years old. All the data were double independently input by professional data entry company to ensure data accuracy. The prevalence of home passive smoking exposure in families with different demographic characteristics was described by using prevalence, and the possible correlated factors of home passive smoking exposure as independent variables, multiple factors were analyzed using Logistic Stepwise Regression Analysis method. The analysis on 8142 nonsmokers revealed that the rate of passive smoking was 28.42%, with 27.38% of male and 28.93% of female suffering from passive smoking. All 87.19% of the smokers would smoke in front of their families. As many as 42.14% of the nonsmokers would offer cigarettes to their guests, while about 46.82% of the nonsmokers would suggest smokers to smoke outdoor. Home restriction on tobacco was extremely rare and only 6.33% of all the families completely forbade smoking. Multivariate logistic regression analysis of non-conditions revealed that, there was a lower level of involuntary tobacco smoke exposure in female, older age group, lower education level, divorced, or widowed families. There was no difference in involuntary tobacco smoke exposure between town dwellers and county dwellers, but such difference did exist in different districts. The three provinces under investigation should have severe involuntary tobacco smoking exposure. Gender, age, literacy level, occupation and region should be all factors that influence the status of

    Waardenburg syndrome (WS) is an auditory‑pigmentary disorder with varying combinations of sensorineural hearing loss and abnormal pigmentation. The present study aimed to investigate the underlying molecular pathology and provide a method of prenatal diagnosis of WS in Chinese families. A total of 11 patients with WS from five unrelated Chinese families were enrolled. A thorough clinical examination was performed on all participants. Furthermore, patients with WS underwent screening for mutations in the following genes: Paired box 3 (PAX3), melanogenesis associated transcription factor (MITF), SRY‑box 10, snail family transcriptional repressor 2 and endothelin receptor type B using polymerase chain reaction sequencing. Array‑based comparative genomic hybridization was used for specific patients whose sequence results were normal. Following identification of the genotype of the probands and their parents, prenatal genetic diagnosis was performed for family 01 and 05. According to the diagnostic criteria for WS, five cases were diagnosed as WS1, while the other six cases were WS2. Genetic analysis revealed three mutations, including a nonsense mutation PAX3 c.583C>T in family 01, a splice‑site mutation MITF c.909G>A in family 03 and an in‑frame deletion MITF c.649_651delGAA in family 05. To the best of the authors' knowledge the mutations (c.583C>T in PAX3 and c.909G>A in MITF) were reported for the first time in Chinese people. Mutations in the gene of interest were not identified in family 02 and 04. The prenatal genetic testing of the two fetuses was carried out and demonstrated that the two babies were normal. The results of the present study expanded the range of known genetic mutations in China. Identification of genetic mutations in these families provided an efficient way to understand the causes of WS and improved genetic counseling.

    With the frequent occurrence of campus violence, scholars have devoted increasing attention to college students' aggression. This study aims to estimate the prevalence of aggression in Chinese university students and identify factors that could influence their aggression. We can thus find methods to reduce the incidence of college students' aggression in the future. A multi-stage stratified sampling procedure was used to select university students (N = 4565) aged 16-25 years in Harbin. The Aggression Questionnaire, the Adolescent Self-Rating Life Events Checklist and the Social Support Revalued Scale were used to collect data. Females reported lower levels of aggression than males (p aggression, and the model was highly significant (R 2  = .233, Ad R 2  = .230, p aggression is affected by gender, family-level and school-level variables. Aggression scores are significantly correlated with not only family-level or school-level variables independently, but their combination as well. We find that the risk factors for aggression include a dissatisfying profession, higher levels of study pressure, poor parental relationships, poor interpersonal relationships, the presence of siblings, punishment, health maladjustment, less subjective support, and lower levels of utilization of social support.

    Norrie disease (ND), a rare X-linked recessive disorder, is characterized by congenital blindness and, occasionally, mental retardation and hearing loss. ND is caused by the Norrie Disease Protein gene (NDP), which codes for norrin, a cysteine-rich protein involved in ocular vascular development. Here, we report a novel mutation of NDP that was identified in a Chinese family in which three members displayed typical ND symptoms and other complex phenotypes, such as cerebellar atrophy, motor disorders, and mental disorders. We conducted an extensive clinical examination of the proband and performed a computed tomography (CT) scan of his brain. Additionally, we performed ophthalmic examinations, haplotype analyses, and NDP DNA sequencing for 26 individuals from the proband's extended family. The proband's computed tomography scan, in which the fifth ventricle could be observed, indicated cerebellar atrophy. Genome scans and haplotype analyses traced the disease to chromosome Xp21.1-p11.22. Mutation screening of the NDP gene identified a novel nonsense mutation, c.343C>T, in this region. Although recent research has shown that multiple different mutations can be responsible for the ND phenotype, additional research is needed to understand the mechanism responsible for the diverse phenotypes caused by mutations in the NDP gene.

Photometric data previous to 1990 have mainly been taken from the Comet Light Curve Catalogue (CLICC) compiled by Kamél (\\cite{kamel}). We discuss the reliability of the reported nuclear magnitudes in relation to the inherent sources of errors and uncertainties, in particular the coma contamination often present even at large heliocentric distances. A large fraction of the JF comets of our sample indeed shows various degrees of activity at large heliocentric distances, which is correlated with recent downward jumps in their perihelion distances. The reliability of coma subtraction methods to compute the nuclear magnitude is also discussed. Most absolute nuclear magnitudes are found in the range 15 - 18, with no magnitudes fainter than H_N ~ 19.5. The catalog can be found at: http://www.fisica.edu.uy/ ~ gonzalo/catalog/.

    The adducin (ADD) family proteins, namely ADD1, ADD2, and ADD3, are actin-binding proteins that play important roles in the stabilization of membrane cytoskeleton and cell-cell junctions. All the ADD proteins contain a highly conserved bipartite nuclear localization signal (NLS) at the carboxyl termini, but only ADD1 can localize to the nucleus. The reason for this discrepancy is not clear. To avoid the potential effect of cell-cell junctions on the distribution of ADD proteins, HA epitope-tagged ADD proteins and mutants were transiently expressed in NIH3T3 fibroblasts and their distribution in the cytoplasm and nucleus was examined by immunofluorescence staining. Several nuclear proteins were identified to interact with ADD1 by mass spectrometry, which were further verified by co-immunoprecipitation. In this study, we found that ADD1 was detectable both in the cytoplasm and nucleus, whereas ADD2 and ADD3 were detected only in the cytoplasm. However, ADD2 and ADD3 were partially (~40%) sequestered in the nucleus by leptomycin B, a CRM1/exportin1 inhibitor. Upon the removal of leptomycin B, ADD2 and ADD3 re-distributed to the cytoplasm. These results indicate that ADD2 and ADD3 possess functional NLS and are quickly transported to the cytoplasm upon entering the nucleus. Indeed, we found that ADD2 and ADD3 possess much higher potential to counteract the activity of the NLS derived from Simian virus 40 large T-antigen than ADD1. All the ADD proteins appear to contain multiple nuclear export signals mainly in their head and neck domains. However, except for the leucine-rich motif ( 377 FEALMRMLDWLGYRT 391 ) in the neck domain of ADD1, no other classic nuclear export signal was identified in the ADD proteins. In addition, the nuclear retention of ADD1 facilitates its interaction with RNA polymerase II and zinc-finger protein 331. Our results suggest that ADD2 and ADD3 possess functional NLS and shuttle between the cytoplasm and nucleus. The discrepancy in the

    Full Text Available The Pre-Qin family education is a long neglected but important research topic in understanding Chinese education and culture. Although Chinese traditional family education is mostly under the influence of Confucianism there is not sufficient discussion in the Pre-Qin period as there are only scattered records related to this topic in various Pre-Qin classics. In addition, most research outputs in the field are on “jiaxun” (family instruction which normally refers to family seniors’ commandments to their juniors from a cultural perspective. However, “jiating jiaoyu” (family education can be defined as a mutual learning process in which individuals are socialized in family settings from perspectives of education and sociology. Based on this definition, the paper aims at exploring the special roles and contributions of the early Pre-Qin Confucian classics to the development of family education in China in terms of principle, aim, pedagogy, and role expectation of family member. The result shows that the Yijing (Book of Changes brings out the views of strict family management style, supreme status of the father and role differentiation in the Pre-Qin period. The Lunyu (Analects emphasizes the value of learning the shi (Book of Songs and the li (Book of Rites while the book Mengzi proposes a couple of innovative views on the parent-child relationship, role models, mutual education, environmental influence, and moral and role expectations in family education. The practicability of impartiality in family education and effectiveness of direct instruction in education are areas that need special attention from researchers and education policy makers.

    Mutations in MYO7A gene have been reported to be associated with Usher Syndrome type 1B (USH1B) and nonsyndromic hearing loss (DFNB2, DFNA11). Most mutations in MYO7A gene caused USH1B, whereas only a few reported mutations led to DFNB2 and DFNA11. The current study was designed to investigate the mutations among a Chinese family with autosomal recessive hearing loss. In this study, we present the clinical, genetic and molecular characteristics of a Chinese family. Targeted capture of 127 known deafness genes and next-generation sequencing were employed to study the genetic causes of two siblings in the Chinese family. Sanger sequencing was employed to examine those variant mutations in the members of this family and other ethnicity-matched controls. We identified the novel compound heterozygous mutant alleles of MYO7A gene: a novel missense mutation c.3671C>A (p.A1224D) and a reported insert mutation c.390_391insC (p.P131PfsX9). Variants were further confirmed by Sanger sequencing. These two compound heterozygous variants were co-segregated with autosomal recessive hearing loss phenotype. The gene mutation analysis and protein sequence alignment further supported that the novel compound heterozygous mutations were pathogenic. The novel compound heterozygous mutations (c.3671C>A and c.390_391insC) in MYO7A gene identified in this study were responsible for the autosomal recessive sensorineural hearing loss of this Chinese family.

    Social aggression is a form of antisocial behavior in which social relationships and social status are used to damage reputations and inflict emotional harm on others. Despite extensive research examining the prevalence and consequences of social aggression, only a few studies have examined its genetic-environmental etiology, with markedly inconsistent results. We estimated the etiology of social aggression using the nuclear twin family (NTF) model. Maternal-report, paternal-report, and teacher-report data were collected for twin social aggression (N = 1030 pairs). We also examined the data using the classical twin (CT) model to evaluate whether its strict assumptions may have biased previous heritability estimates. The best-fitting NTF model for all informants was the ASFE model, indicating that additive genetic, sibling environmental, familial environmental, and non-shared environmental influences significantly contribute to the etiology of social aggression in middle childhood. However, the best-fitting CT model varied across informants, ranging from AE and ACE to CE. Specific heritability estimates for both NTF and CT models also varied across informants such that teacher reports indicated greater genetic influences and father reports indicated greater shared environmental influences. Although the specific NTF parameter estimates varied across informants, social aggression generally emerged as largely additive genetic (A = 0.15-0.77) and sibling environmental (S = 0.42-0.72) in origin. Such findings not only highlight an important role for individual genetic risk in the etiology of social aggression, but also raise important questions regarding the role of the environment.

    Fanconi anemia (FA) is a rare autosomal recessive or X-linked disorder with highly variable clinical manifestations and an incidence of ∼1 to 5 in 1 million births. To date, 15 bona fide FA genes have been reported to be responsible for the known FA complementation groups and the FANCA gene accounts for almost 60%. In the present study, we report a special Chinese family, which has 2 children with classic FA characteristics. Via 2-step analysis of the whole-exome sequencing data and verification using multiplex ligation-dependent probe amplification test, one child was found to have a novel compound heterozygous mutation of a splicing variant (c.1471-1G>A) and a large intragenic deletion (exons 23-30 del) of the FANCA gene. The other child had the same splicing variant and another novel large deletion (exons 1-18 del) in the FANCA gene. Clone sequencing showed the c.1471-1G>A variant generate an altered transcript with 1 cryptic splice site in intron 15, resulting in a premature termination codon (p.Val490HisfsX6). This study not only shows the complexity of FA molecular diagnosis via comprehensively studying the FA pathogenic genes and the mutational spectrum, but also has significant reference value for the future molecular diagnosis of FA.

    Climate is one of the most important factors determining crop yields and world food supplies. To be well prepared for possible futures, it is necessary to study yield changes of major crops under different climate scenarios. Here we consider two situations: stratospheric sulfate geoengineering and nuclear war. Although we certainly do not advocate either scenario, we cannot exclude the possibilities: if global warming is getting worse, society might consider deliberately manipulating global temperature; if nuclear weapons still exist, we might face a nuclear war catastrophe. Since in both scenarios there would be reductions of temperature, precipitation, and insolation, which are three controlling factors on crop growth, it is important to study food supply changes under the two cases. We conducted our simulations for China, because it has the highest population and crop production in the world and it is under the strong influence of the summer monsoon, which would be altered in geoengineering and nuclear war scenarios. To examine the effects of climate changes induced by geoengineering and nuclear war on Chinese agriculture, we use the Decision Support System for Agrotechnology Transfer (DSSAT) crop model. We first evaluated the model by forcing it with daily weather data and management practices for the period 1978-2008 for 24 provinces in China, and compared the results to observations of the yields of major crops in China (middle season rice, winter wheat, and maize). Then we perturbed observed weather data using climate anomalies for geoengineering and nuclear war simulations. For geoengineering, we consider the G2 scenario of the Geoengineering Model Intercomparison Project (GeoMIP), which prescribes an insolation reduction to balance a 1% per year increase in CO2 concentration (1pctCO2). We used results from ten climate models participating in G2. For the nuclear war scenario, we consider the effects of 5 Tg of soot that could be injected into the upper

    The crude divorce rate has been increasing steadily for over a decade in China. Consequently, more and more children have to face the challenge of growing up in single parent families. The current study investigated the mediating effects of problem-oriented and emotion-oriented coping on the relationship between parental attachment and psychological resilience among a sample of Chinese adolescents from single parent families and intact families. Participants were 975 high school students (44.30% males; aged 15-19 years, M = 16.32 years, SD = 0.74), 871 from intact families and 104 from single parent families. Structural equation modeling showed that security in maternal attachment was positively associated with resilience through the indirect effect of reduced emotion-oriented coping among adolescents from single parent families. Among adolescents from intact families, security in maternal attachment was both directly associated with resilience and indirectly through enhanced problem-oriented and reduced emotion-oriented coping. Security in paternal attachment was associated with resilience both directly and indirectly through enhanced problem-oriented coping as well among those from intact families. Female adolescents exhibited significantly lower levels of resilience than male adolescents did regardless of the marital status of their parents. Limitations and suggestions for future research are discussed.

    Projects are characterized by long working hours, complex tasks and being a kind of temporary organization. As such, work-family conflict is particularly prominent for project employees. This research examined whether and how work-family conflict affects professional commitment among Chinese project professionals. Research hypotheses were developed to explore the relationship between work-family conflict, professional commitment to the project and the mediating effects of perceived organizational support. Data were collected from 327 project managers or professionals working in construction enterprises in China; data were analyzed using structural equation modeling, applying the bootstrapping method. Results showed that there were three dimensions of work-family conflict: time-based conflict, strain-based conflict and behavior-based conflict. There were two dimensions of perceived organizational support: emotional support and instrumental support. The study also tested the negative effect of work-family conflict on professional commitment and the positive effect of perceived organizational support on professional commitment. Specifically, time-based conflict and emotional support had positive effects on professional commitment. Perceived organizational support had a total mediating effect between work-family conflict and professional commitment. The strain-based conflict dimension of work-family conflict had negative impacts on professional commitment through perceived emotional support and instrumental support. Overall, our findings extend a better understanding of work-family conflict and professional commitment in the project setting and verify the importance of social support in balancing work and family and improving employee mobility.

    Oculocutaneous albinism (OCA) is a group of heterogeneous and autosomal recessive disorders characterized by a reduction or complete loss of melanin biosynthesis in melanocytes. OCA type 1 (OCA1) is the most severe and common form of OCA, and is caused by mutations in the tyrosinase gene (TYR). The present study aimed to identify the genetic cause of OCA1 in a four‑generation consanguineous Chinese Han family. Complete physical examinations were performed and blood samples were collected from five members of the family and 100 unrelated healthy controls. Exome sequencing was conducted in the proband, followed by verification in other family members, using Sanger sequencing. Patients in the family presented with typical OCA1 features, including hypopigmentation of the skin and hair, and distinctive ocular changes. A homozygous missense variant, c.896G>A (p.R299H), in the TYR gene was identified in two patients, which co‑segregated with disease in the family. This variant was not present in the 100 healthy controls. These results expand the number of mutations identified to be responsible for OCA1 in the Chinese Han population, and may have implications for genetic counseling and clinical management of the disease.

    To examine the associations of perceived interparental relationship, family harmony and family happiness with smoking intention in never-smoking Chinese children and adolescents in Hong Kong. Cross-sectional surveys of 15 753 primary (grades 4-6) and 38 398 secondary (grades 7-12) never-smoking students from 71 to 75 randomly selected primary and secondary schools in Hong Kong, 2012-2013. Outcome variable was smoking intention which denoted any affirmative response to smoke within the coming year or when a cigarette was offered by a good friend. Exposure variables were perceived interparental relationship and family harmony each measured on a five-point scale from 'very good' to 'very bad' and perceived family happiness on a four-point scale from 'very happy' to 'not happy at all'. Potential confounders included age, sex, family structure, perceived family affluence, parental smoking and sibling smoking. In primary students, the adjusted ORs (AORs) (95% CI) of smoking intention generally increased with more negative perception of the family relationship: up to 3.67 (1.91 to 7.05) for interparental relationship, 7.71 (4.38 to 13.6) for family harmony and 5.40 (3.41 to 8.55) for family happiness. For secondary students, the corresponding AORs (95% CI) were 2.15 (1.64 to 2.82) for interparental relationship, 2.98 (2.31 to 3.84) for family harmony and 2.61 (1.80 to 3.79) for family happiness. All p for trend happiness were associated with higher odds of smoking intention with dose-response relationships in never-smoking Chinese children and adolescents in Hong Kong. Children's perception of their family relationship may be an important intervening point for preventing youth from initiating smoking. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    Sarcopenia is defined as the age-related decline in skeletal muscle mass and function. The risk factors and causes of sarcopenia must be identified to develop prevention and treatment strategies for this syndrome. Our aim was to examine the association between sarcopenia with lifestyle and family function among community-dwelling Chinese people aged 60 years and older. We conducted this study to evaluate sarcopenia among 834 community-dwelling Chinese individuals aged ≥60 years using the Asian Working Group for Sarcopenia (AWGS) criteria. The sociodemographic characteristics, food consumption patterns, habits of smoking, and alcohol consumption of the participants were collected using a general questionnaire, whereas physical activity was assessed using the International Physical Activity Questionnaire (IPAQ; long-form version). Family function was assessed using the Family APGAR scale. In addition, the association of sarcopenia with lifestyle and family function was examined using univariate and multivariate analyses. The total prevalence rate of sarcopenia was 10.6%. Female participants with sarcopenia had a lower frequency per week of nut consumption than those without sarcopenia (p sarcopenia versus those without sarcopenia were not significant. Among the participants, the mean Family APGAR score was 8 (standard deviation [SD] = 0.92). For both sexes, participants with sarcopenia had lower family function scores than those without sarcopenia. In the multivariate model, after adjustment for all covariates, frequency per week of nut consumption (adjusted OR 0.724, 95% CI 0.532-0.985, P sarcopenia. The relationship between other lifestyle habits and sarcopenia was not significant. There was significant association between sarcopenia with intake of nuts and family function. Further studies should evaluate if adequate intake of nuts and a well-functioning family may be effective in lowering the risk of sarcopenia.

    Little is known about the information sources of Chinese patients with cancer and their family caregivers, yet this knowledge is critical for providing patient-centred care. To assess and compare the information sources used by Chinese patients with cancer and their family caregivers. The validated Health Information Wants Questionnaire (HIWQ) was translated and administered in March 2014. The oncology department of a general hospital in south-west China. A convenience sample of 198 individuals, including 79 patients with cancer (mean age=55.24, SD=13.80) and 119 family caregivers (mean age=46.83, SD=14.61). Ratings on the HIWQ items assessing information sources for different types of information. The interaction between information source and group was significant (F 3,576 =6.32, Pinformation than patients from the Internet. Caregivers and patients did not differ in the amount of information they obtained from doctors/nurses, interpersonal contacts or mass media. The interaction between information type and information source was significant (F 18,3456 =6.38, Pinformation of all types from doctors/nurses than from the other three sources and obtained more information from interpersonal contacts than from mass media or the Internet. The information sources of Chinese patients with cancer and their family caregivers were similar, with an important difference that caregivers obtained more online information than patients. These findings have important implications for patient care and education in China where the family typically plays a major role in the care and decision making. © 2016 The Authors.

    Full Text Available The current study investigated the differences between intact and non-intact families in family processes, including systematic family functioning, parental behavioral control, parental psychological control, and parent-child relational qualities. The participants were 3,328 Secondary One students, with a mean age of 12.59 years, recruited from 28 secondary schools in Hong Kong. Four validated scales were used to assess family processes. Results showed that adolescents in non-intact families perceived relatively poorer family functioning, lower level of paternal and maternal behavioral control, lower level of paternal psychological control and poorer parent-child relational qualities than did adolescents in intact families. This generally indicated that family processes were poorer in non-intact families, compared with those in intact families. The theoretical and practical implications of the findings were discussed.

Participants comprised of 80 father-child dyads and 169 mother-child dyads from families with ODD children. The results indicated that multilevel family factors were differently associated with children's affective and behavioral ODD symptoms. All the family factors at the dyadic and individual levels were significantly associated with child affective ODD symptoms. However, only the most proximal factors (parent-child relationship and child emotion regulation, which were directly related to child were significantly related to child behavioral ODD symptoms. The present study extends the current knowledge regarding the relationships between family factors and two dimensions of child ODD symptoms by testing the comprehensive multilevel family factors model. This study also recommends that future interventions for ODD children should consider the multi-level family factors to enhance intervention efficacy.

    Full Text Available Vietnamese species from the family Plectopylidae are revised based on the type specimens of all known taxa, more than 600 historical non-type museum lots, and almost 200 newly-collected samples. Altogether more than 7000 specimens were investigated. The revision has revealed that species diversity of the Vietnamese Plectopylidae was previously overestimated. Overall, thirteen species names (anterides Gude, 1909, bavayi Gude, 1901, congesta Gude, 1898, fallax Gude, 1909, gouldingi Gude, 1909, hirsuta Möllendorff, 1901, jovia Mabille, 1887, moellendorffi Gude, 1901, persimilis Gude, 1901, pilsbryana Gude, 1901, soror Gude, 1908, tenuis Gude, 1901, verecunda Gude, 1909 were synonymised with other species. In addition to these, Gudeodiscus hemmeni sp. n. and G. messageri raheemi ssp. n. are described from north-western Vietnam. Sixteen species and two subspecies are recognized from Vietnam. The reproductive anatomy of eight taxa is described. Based on anatomical information, Halongella gen. n. is erected to include Plectopylis schlumbergeri and P. fruhstorferi. Additionally, the genus Gudeodiscus is subdivided into two subgenera (Gudeodiscus and Veludiscus subgen. n. on the basis of the morphology of the reproductive anatomy and the radula. The Chinese G. phlyarius werneri Páll-Gergely, 2013 is moved to synonymy of G. phlyarius. A spermatophore was found in the organ situated next to the gametolytic sac in one specimen. This suggests that this organ in the Plectopylidae is a diverticulum. Statistically significant evidence is presented for the presence of calcareous hook-like granules inside the penis being associated with the absence of embryos in the uterus in four genera. This suggests that these probably play a role in mating periods before disappearing when embryos develop. Sicradiscus mansuyi is reported from China for the first time.

    Abstract Depressive symptoms are related to negative health outcomes in caregivers of patients with HF. Understanding the factors that are associated with depressive symptoms among caregivers is essential to providing appropriate interventions. Little is known about which status and factors are related to depressive symptoms among Chinese caregivers of patients with heart failure. This study aimed to investigate the status of depressive symptoms and to identify the factors that are associated with depressive symptoms in family caregivers of patients with heart failure in China. A cross-sectional design and a convenience sample were used. Participants (N = 134) from 1 hospital in Chengdu were recruited from June 2013 to June 2014. The following measurement tools were used in this study: Center for Epidemiologic Studies Depression Scale, Hospital Anxiety and Depression Scale, Coping Strategies Simplified Coping Style Questionnaire, and Zarit Burden Interview. A hierarchical multiple linear regression analysis was used to determine which factors were associated with depressive symptoms. The results showed that 31% of the caregivers experienced depressive symptoms. The type of payment for treatment (b = −0.312, P caregiving (b = −0.213, P caregiver burden (b = 0.299, P caregivers’ depressive symptoms. Fifty-four percent of the variance in caregivers’ depressive symptoms was explained by these factors. The caregiver depressive symptoms in China were higher than those reported in studies that were conducted in Western countries. Caregiver depressive symptoms can be improved by providing support for new caregivers (with a caregiving duration of less than 1 year), reducing readmissions, easing caregiver burden, and promoting their coping strategies.

    Full Text Available Tectorial membrane, an extracellular matrix of the cochlea, plays a crucial role in the transmission of sound to the sensory hair cells. Alpha-tectorin is the most important noncollagenous component of the tectorial membrane and the otolith membrane in the maculae of the vestibular system. Defects in TECTA, the gene encodes alpha-tectorin, are cause of both dominant (DFNA8/12 and recessive (DFNB21 forms of deafness. Here, we report a three-generation Chinese family characterized by prelingual progressive sensorineural hearing impairment. We mapped the disease locus to chromosome 11q23-24 region, overlapping with the DFNA8/12 locus. Sequencing of candidate gene TECTA revealed a heterozygous c.5945C>A substitution in exon 19, causing amino acid substitution of Ala to Asp at a conservative position 1982. The A1982D substitution is consistent with hearing loss in this Chinese family and has not been found in 200 random control chromosomes. To our knowledge, this is the first TECTA mutation identified in Chinese population. Our data provides additional molecular and clinical information for establishing a better genotype-phenotype understanding of DFNA8/12.

    Oculocutaneous albinism (OCA) is an autosomal recessive disorder. The most common type OCA1 and OCA2 are caused by homozygous or compound heterozygous mutations in the tyrosinase gene (TYR) and OCA2 gene, respectively. The purpose of this study was to evaluate the molecular basis of oculocutaneous albinism in four Chinese families. Four non-consanguineous OCA families were included in the study. The TYR and OCA2 genes of all individuals were amplified by polymerase chain reaction (PCR), sequenced and compared with a reference database. Four patients with a diagnosis of oculocutaneous albinism, presented with milky skin, white or light brown hair and nystagmus. Genetic analyses demonstrated that patient A was compound heterozygous for c.1037-7T.A, c.1037-10_11delTT and c.1114delG mutations in the TYR gene; patient B was heterozygous for c.593C>T and c.1426A>G mutations in the OCA2 gene, patients C and D were compound heterozygous mutations in the TYR gene (c.549_550delGT and c.896G>A, c.832C>T and c.985T>C, respectively). The heterozygous c.549_550delGT and c.1114delG alleles in the TYR gene were two novel mutations. Interestingly, heterozygous members in these pedigrees who carried c.1114delG mutations in the TYR gene or c.1426A>G mutations in the OCA2 gene presented with blond or brown hair and pale skin, but no ocular disorders when they were born; the skin of these patients accumulated pigment over time and with sun exposure. This study expands the mutation spectrum of oculocutaneous albinism. It is the first time, to the best of our knowledge, to report that c.549_550delGT and c.1114delG mutations in the TYR gene were associated with OCA. The two mutations (c.1114delG in the TYR gene and c.1426A>G in the OCA2 gene) may be responsible for partial clinical manifestations of OCA.

    This study tested the relationship between grandparent-grandchild family capital and self-rated health of older rural Chinese adults and the mediating role of the grandparent-parent relationship in terms of grandparent-grandchild family capital and self-rated health. Data were derived from a random sample of 1,027 adults aged 60 and older who were interviewed in the rural Chaohu region in 2009. Structural equation modeling was used to examine the direct effect of grandparent-grandchild family capital in terms of relations with the first child's family on self-rated health among respondents, as well as the mediating effect of the grandparent-parent relationship. The results showed the direct effect of grandparent-grandchild family capital on self-rated health of older rural Chinese adults. The grandparent-parent relationship had a partial mediation effect on the relationship between grandparent-grandchild family capital and self-rated health of respondents. Grandparent-grandchild family capital had a unique direct effect on the self-rated health of older rural Chinese adults, enriching our theoretical understanding of sources of family capital and their impacts in a collectivist cultural context that emphasizes intergenerational interaction and exchange. The findings also highlighted the mediation effects of grandparent-parent relationships on the relationship between grandparent-grandchild family capital and self-rated health of older rural Chinese adults, supporting the "grandchild-as-linkage" hypothesis in understanding the social determination of self-rated health in China.

    Full Text Available Abstract Background Interspecific hybridization may lead to the introgression of genes and genomes across species barriers and contribute to a reticulate evolutionary pattern and thus taxonomic uncertainties. Since several previous studies have demonstrated that introgressive hybridization has occurred among some species within Lepus, therefore it is possible that introgressive hybridization events also occur among Chinese Lepus species and contribute to the current taxonomic confusion. Results Data from four mtDNA genes, from 116 individuals, and one nuclear gene, from 119 individuals, provides the first evidence of frequent introgression events via historical and recent interspecific hybridizations among six Chinese Lepus species. Remarkably, the mtDNA of L. mandshuricus was completely replaced by mtDNA from L. timidus and L. sinensis. Analysis of the nuclear DNA sequence revealed a high proportion of heterozygous genotypes containing alleles from two divergent clades and that several haplotypes were shared among species, suggesting repeated and recent introgression. Furthermore, results from the present analyses suggest that Chinese hares belong to eight species. Conclusion This study provides a framework for understanding the patterns of speciation and the taxonomy of this clade. The existence of morphological intermediates and atypical mitochondrial gene genealogies resulting from frequent hybridization events likely contribute to the current taxonomic confusion of Chinese hares. The present study also demonstrated that nuclear gene sequence could offer a powerful complementary data set with mtDNA in tracing a complete evolutionary history of recently diverged species.

    Although depression is a major problem affecting the physical and mental health of the occupational population worldwide, little research is available among bank employees. The purpose of the study was to examine the effects of occupational stress and work-family conflict on depressive symptoms and the mediating role of psychological capital (PsyCap). A cross-sectional study was performed from May to June in 2013 in Liaoning province, China. The effort-reward imbalance (ERB) scale, the work-family conflict scale, the PsyCap questionnaire and the Center for Epidemiologic Studies Depression scale were completed by 1546 employees in state-owned banks. A total of 1239 effective respondents (467 men and 772 women) became our subjects. Hierarchical regression analysis was carried out to explore the effects of extrinsic effort, reward, overcommitment, work-family conflict, and PsyCap on depressive symptoms. The mediating role of PsyCap was examined using Preacher and Hayes' asymptotic and resampling strategies. The mean score of depressive symptoms was 18.4 (SD = 7.6) among the Chinese bank employees. Extrinsic effort, overcommitment and work-family conflict were positively associated with depressive symptoms. Reward and PsyCap were negatively associated with depressive symptoms. The significant mediating roles of PsyCap in the associations of extrinsic effort (a*b = 0.046, BCa 95% CI: 0.029, 0.066) and reward (a*b = -0.047, BCa 95% CI: -0.065, -0.030) with depressive symptoms were revealed. There is a high level of depressive symptoms among Chinese bank employees. PsyCap partially mediates the effects of extrinsic effort and reward on depressive symptoms. Investing in PsyCap may provide new approaches to improve mental health among Chinese bank employees.

    Full Text Available Depression is a major mental health problem during adolescence. This study, using a sample of Chinese adolescents, examined the separate and combined effects of perceived school-related stress and of family socioeconomic status (SES on the prevalence of depressive symptoms. A total of 1774 Chinese students from Grades 7–12 were recruited into our questionnaire survey. School-related stress was measured by the Effort-Reward Imbalance Questionnaire-School Version, family SES was assessed by a standardized question, and depressive symptoms were evaluated by the Center for Epidemiological Studies Depression Scale for Children. Multivariate logistic regression was applied, adjusting for age, gender, grade, smoking, alcohol drinking and physical activity. It was found that high school-related stress and low family SES were associated with elevated odds of depressive symptoms, respectively. The effect of school-related stress was particularly strong in low SES group. In adolescents with both high stress at school and low SES, the odds ratio was 9.18 (95% confidence interval = 6.53–12.89 compared to the reference group (low stress at school and high SES. A significant synergistic interaction effect was observed (synergy index = 2.28, 95% confidence interval = 1.56–3.32. The findings indicated that perceived school-related stress, in terms of effort-reward imbalance, was related to depressive symptoms in this sample of Chinese adolescents. The strong interaction with family SES suggests that health promoting efforts in school settings should be targeted specifically at these socially deprived groups.

    Due to the requirements of the competitive, market-oriented urban society, parents in urban and urbanized families are more likely than parents in rural families to encourage initiative-taking in child rearing in China. The socialization experiences of children from different types of families may be related to their adjustment. This study examined parental socialization attitudes, social and school adjustment, and their relations in Chinese children from rural, urban, and urbanized families. Participants were elementary school students (N = 1,033; M age = 11 years) and their parents in China. Data were obtained from parental reports, peer evaluations, teacher ratings, and school records. A multivariate analysis of variance revealed that parents in urban and urbanized families had higher scores than parents in rural families on encouragement of initiative-taking. Urban children, particularly girls, were more sociable, obtained higher social status, and had fewer school problems than their rural counterparts. Children from urbanized families were different from rural children and similar to urban children in social and school adjustment. Moreover, multigroup invariance tests showed that parental encouragement of initiative-taking was associated more strongly with children's sociable-assertive behavior and social standing in the urban and urbanized groups than in the rural group. The results indicate that particular socialization attitudes may vary in their adaptive value in child development as a function of specific social and cultural requirements in changing societies.

    A variety of 5 different models of nuclear interaction has been used in a Monte Carlo simulation of nuclear and electromagnetic showers in the atmosphere. The gamma families obtained from this simulation were processed in a way, analogous to one employed in analysis of Pamir experimental results. The sensitivity of observed pattern to the nuclear interaction model assumptions was investigated. Such sensitivity, though not a strong one, was found. In case of longitudinal (or energetical) family characteristics, the changes in nuclear interaction should be really large, if they were to be reflected in the experimental data -with all methodical error possibilities. The transverse characteristics of gamma families are more sensitive to the assumed transverse momentum distribution, but they feel the longitudinal features of nuclear interaction as well. Additionally, there was tested the dependence of observed family pattern on some methodical effects (resolving power of X-ray film, radial cut-off and energy underestimation.) (author)

    This volume explores how cultural and family contexts inform parent-adolescent conflict and adjustment among Chinese- and Mexican-origin families in the United States. Collectively, the chapters examine outcomes associated with family conflict and provide an in-depth analysis of how and for whom conflict is related to adjustment. Findings, for example, illustrate how cultural factors (e.g., acculturation) modify the links between conflict and adjustment. Furthermore, the collection allows for a simultaneous examination of normative, everyday parent-adolescent conflict and conflict that is specific to the process of cultural adaptation, and furthers our understanding of how both developmental and cultural sources of conflict are linked to adjustment. © 2012 Wiley Periodicals, Inc., A Wiley Company.

    Over the past two decades, there is increasing emphasis being placed upon providing family-centred care (FCC) in paediatric oncology settings. However, there is a lack of knowledge of FCC in paediatric oncology from the perspectives of immigrant parents. The purpose of this paper is to describe Chinese and South Asian immigrant parents' experiences of FCC in paediatric oncology settings in Canada. This study adopted a constructivist grounded theory approach. Fifty first generation Chinese and South Asian parents of children with cancer who were at least 6 months post-diagnosis were recruited from six Canadian paediatric oncology centres. Interviews were conducted in English, Cantonese, Mandarin, Urdu, Punjabi or Hindi, and transcribed into English. Analysis involved line-by-line, focused and theoretical coding, and the use of the constant comparison method. Findings indicated that overall parents were highly satisfied with the care and services they received, and their experiences were reflective of the key elements of FCC. However, there were some areas of concern identified by participants: parents not perceiving themselves as a member of the medical team; inconsistency in the quality and co-ordination of services among healthcare providers; disrespectful and mechanical manner of a few healthcare providers; and parents' discomfort with healthcare providers communicating sensitive health-related information directly with their child. In order to successfully provide family-centred services to immigrant parents of children with cancer, better communication of the elements of FCC between healthcare staff and families is needed to negotiate a clear role for the parents as partners of the healthcare team. Moreover, a better understanding of how family relationships are structured in immigrant families will assist healthcare providers to balance the best interests of the child with that of the family as a unit. © 2011 Blackwell Publishing Ltd.

    Waardenburg syndrome is a rare genetic disorder, inherited as an autosomal dominant trait. The condition is characterized by sensorineural hearing loss and pigment disturbances of the hair, skin, and iris. The de novo mutation in the SOX10 gene, responsible for Waardenburg syndrome type II, is rarely seen. The present study aimed to identify the genetic causes of Waardenburg syndrome type II in a Chinese family. Clinical and molecular evaluations were conducted in a Chinese family with Waardenburg syndrome type II. A novel SOX10 heterozygous c.259-260delCT mutation was identified. Heterozygosity was not observed in the parents and sister of the proband, indicating that the mutation has arisen de novo. The novel frameshift mutation, located in exon 3 of the SOX10 gene, disrupted normal amino acid coding from Leu87, leading to premature termination at nucleotide 396 (TGA). The high mobility group domain of SOX10 was inferred to be partially impaired. The novel heterozygous c.259-260delCT mutation in the SOX10 gene was considered to be the cause of Waardenburg syndrome in the proband. The clinical and genetic characterization of this family would help elucidate the genetic heterogeneity of SOX10 in Waardenburg syndrome type II. Moreover, the de novo pattern expanded the mutation data of SOX10. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

    This study investigated the role of social support in the complex pattern of associations among stressors, work-family interferences and depression in the domains of work and family. A questionnaire was administered to a nationwide sample of 11,419 Chinese science and technology professionals. Several structural equation models were specified to determine whether social support functioned as a predictor or a mediator. Using Mplus 5.0, we compared the moderation model, the independence model, the antecedent model and the mediation model. The results revealed that the relationship between work-family interference and social support was domain specific. The independence model fit the data best in the work domain. Both the moderation model and the antecedent model fit the family domain data equally well. The current study was conducted to answer the need for comprehensive investigations of cultural uniqueness in the antecedents of work-family interference. The domain specificity, i.e. the multiple channels of the functions of support in the family domain and not in the work domain, ensures that this study is unique and culturally specific.

    SYNOPSIS Objectives Parents from different cultures differ in how frequently they express emotions. However, the generalizability of the relations between parental expressivity and child adjustment in non-Western cultures has not been extensively studied. The goal of the present study was to investigate prospective relations between parental expressivity within the family (positive, negative dominant, and negative submissive expressivity) and Chinese children’s psychological adjustment, above and beyond parenting styles. Design The study used two waves (3.8 years apart) of longitudinal data from a sample (n= 425) of children in Beijing (mean ages = 7.7 years at T1 and 11.6 years at T2). Parental expressivity and parenting styles were self-reported. To reduce the potential measurement overlap, items that tap parental expression of emotions toward the child were removed from the parenting style measure. Children’s adjustment was measured with parents’, teachers’, and peers’ or children’s reports. Results Consistent with findings with European American samples, parental negative dominant expressivity uniquely and positively predicted Chinese children’s externalizing problems controlling for prior externalizing problems, parenting styles, and family SES. Neither parental expressivity nor parenting styles uniquely predicted social competence. Conclusions Despite previously reported cultural differences in the mean levels of parental expressivity, some of the socialization functions of parental expressivity found in Western countries can be generalized to Chinese families. Although parental expressivity and parenting styles are related constructs, their unique relations to child’s adjustment suggest that they should be examined as distinct processes. PMID:23226715

    Full Text Available Duration of untreated psychosis (DUP is a potentially modifiable prognostic factor of course and prognosis of psychiatric disorders. Few studies have demonstrated that different cultural backgrounds or perspectives on psychosis may be important factors to the DUP. This study attempted to explore whether the DUP was different in Chinese and Mauritians and to clarify potential influencing factors to a long DUP (>3 months.200 patients from China and 100 patients from Mauritius were enrolled in the study. Their respective family members were also recruited. Demographic and clinical characteristics were collected, and the Internalized Stigma of Mental Illness (ISMI scale was adapted to measure the stigma in all subjects. Binary logistic regression analysis was used to find the potential influencing factors to the long DUP.35.3% of the enrolled patients had a long DUP. No significant difference was found in frequency of long DUP between the two countries. Chinese patients had relatively less perceptions of stigma. Furthermore, Chinese patients with a long DUP had more perception of breakup due to mental illness (OR = 2.22, p = 0.04 and more families' perception of the patient being disinherited due to mental illness (OR = 6.47, p = 0.01. Mauritian patients with a long DUP were less likely to have high monthly income (OR = 0.12, p<0.01, while they had less patients' awareness of mental illness (OR = 0.31, p<0.05 and less families' awareness of mental illness (OR = 0.14, p<0.01.The results of this study underlined the importance of DUP in economic conditions, racial and sociocultural factors, and public awareness on psychosis in developing countries.

    Hb Q-Thailand [α74(EF3)Asp→His (α1); HBA1: c.223 G>C] is an abnormal hemoglobin (Hb), variant found mainly in China and Southeast Asian countries. The association of the α Q -Thailand allele with other globin gene disorders has important implications in diagnosis. Here, we report a hitherto undescribed condition of patients with a double heterozygosity for Hb Q-Thailand with α 0 -thalassemia (α 0 -thal) and in combination with β 0 -thalassemia (β 0 -thal) in a Chinese family. Our study will provide some clinical manifestations, laboratory diagnosis and genetic counseling for complex hemoglobinopathies.

    Two cases of hemolytic disease of new born in a Chinese family are reported. The hemolysis was due to the production in the mother of antibodies against fractions A, C, and D of Rh(D) antigen. The fractions were absent in the mother's red blood cells which are Rh(DB) but present in her babies. Rh(DB) may be detected by the use of two types of anti-D sera, one with and the other without anti-DB activity. For transfusion purpose, all DB patients so tested, would be regarded as Rh(D) negative.

For both groups, self-esteem scores were positively correlated with social support scores, while negatively correlated with FAD all sub-scale scores. Hierarchical regression analysis showed that for the students with grandparenting experience the social support moderated the relationship between GF and self-esteem. When students reported a high level of social support, those with low GF score reported higher scores in self-esteem than those with low self-esteem. However, in case of low social support, there were no differences in self-esteem between groups with high and low GF scores. These findings suggest that social support plays a positive role to relieve the adverse impact of poor family function on self-esteem of the adolescents with grandparenting experience. In addition, the significance and limitations of the results will be discussed.

    Japan and the United States signed in 1968 a new atomic energy agreement through which US light-water nuclear reactors, including those of the Fukushima Daiichi Nuclear Power Plant of Tokyo Electric Power Company, were to be introduced into Japan. This paper studies the history of negotiations for the 1968 agreement using documents declassified in the 1990s in the US and Japan. After the success of the Chinese nuclear test in October 1964, the United States became seriously concerned about nuclear armament of other countries in Asia including Japan. Expecting that Japan would not have its own nuclear weapons, the US offered to help the country to demonstrate its superiority in some fields of science including peaceful nuclear energy to counter the psychological effect of the Chinese nuclear armament. Driven by his own political agenda, the newly appointed Prime Minister Eisaku Sato responded to the US expectation favorably. When he met in January 1965 with President Johnson, Sato made it clear that Japan would not pursue nuclear weapons. Although the US continued its support after this visit, it nevertheless gave priority to the control of nuclear technology in Japan through the bilateral peaceful nuclear agreement. This paper argues that the 1968 agreement implicitly meant a strategic measure to prevent Japan from going nuclear and also a tactic to persuade Japan to join the Nuclear Non -Proliferation Treaty.

    We report here the clinical, genetic, and molecular characterization of a four-generation Chinese family with aminoglycoside-induced and nonsyndromic hearing loss. Five of nine matrilineal relatives had aminoglycoside-induced hearing loss. These matrilineal relatives exhibited variable severity and audiometric configuration of hearing impairment, despite sharing some common features: being bilateral and having sensorineural hearing impairment. Sequence analysis of mitochondrial DNA (mtDNA) in the pedigree identified 16 variants and the homoplasmic 12S rRNA C1494T mutation, which was associated with hearing loss in the other large Chinese family. In fact, the occurrence of the C1494T mutation in these genetically unrelated pedigrees affected by hearing impairment strongly indicated that this mutation is involved in the pathogenesis of aminoglycoside-induced and nonsyndromic hearing loss. However, incomplete penetrance of hearing loss indicated that the C1494T mutation itself is not sufficient to produce a clinical phenotype but requires the involvement of modifier factors for the phenotypic expression. Those mtDNA variants, showing no evolutional conservation, may not have a potential modifying role in the pathogenesis of the C1494T mutation. However, nuclear background seems to contribute to the phenotypic variability of matrilineal relatives in this family. Furthermore, aminoglycosides modulate the expressivity and penetrance of deafness associated with the C1494T mutation in this family

    In China, not only patients and physicians are involved in medical decision-making (MDM) but also the patients' family members. The objective is to investigate the willingness and actual situation of cancer patients and their family members participating in the MDM process. In this cross-sectional study, questionnaires were administered to 247 pairs of cancer inpatients and their relatives. Information regarding participants' willingness and actual experience during the decision-making process was documented. Eligible participants were cancer inpatients or their relatives, 18 years of age or older, and informed of the cancer diagnosis. All the patients should have received chemotherapy. The effective response rate was 72.9% (180/247). Over half of the patients (53.3%) and family members (57.8%) were willing to be part of the MDM process. In contrast, only 35.0% of patients and 46.1% of family members actually experienced this process (p = 0.001 and p = 0.011, respectively). Fewer family members (42.2%) than patients (53.3%) believed that patients should be involved in the MDM process (p family (odds ratio 2.577, 95% CI 1.198-5.556, p = 0.015) experienced more involvement in MDM. Although more than half of Chinese cancer patients and family members wanted to be part of MDM, the actual participation was below their expectation. Majority of family members do not want the patients to be involved in the process of MDM. Copyright © 2015 John Wiley & Sons, Ltd.

    Decision making for an incompetent patient at the end of life is difficult for both family members and physicians alike. Often, palliative care teams are tasked with weaving through opinions, emotions, and goals in search for an amenable solution. Occasionally, these situations get challenging. We present the case of an elderly Chinese Singaporean with metastatic cancer, whose family and physicians had conflicting goals of care. The former was adamant on treating the patient's disease with an untested drug, whereas the latter aimed to treat his symptoms with more conventional medication. Drug-drug interactions prevented treatment with both. Beginning with a discussion of the patient's best interest, we delve into the Singaporean context to show how culture affects medical decision making. Confucianism and filial piety are the values on which this family's workings were based. In an analysis of what this entails, we attempt to explain the significant and assertive family involvement in the decision-making process and their insistence on using novel medications, having exhausted conventional interventions. Within this mix were Western influences, too. Through the Internet, family members have become more informed and empowered in decision making, wresting the traditional paternalistic role of physicians in favor of "patient autonomy." An understanding of such dynamic facets will help better tailor culturally appropriate approaches to such complex situations. Copyright © 2010 U.S. Cancer Pain Relief Committee.

    Family influence plays an important role in a child's physical activity (PA). This study aimed to describe the level of moderate to vigorous intensity physical activity (MVPA) and sedentary behaviours among Chinese junior high school students and examine the associations between different types of family influence and MVPA or sedentary behaviours. Participants of two independent cross-sectional surveys, conducted in 2009 and 2011, were students in Grade 7 and 9 from all junior high schools in Hangzhou, China. The daily duration and frequency of MVPA, amount of sedentary time and frequency of family support were self-reported. Multi-level mixed-effects logistic regression was used to examine the associations between different types or levels of family influence and MVPA or sedentary behaviours. A total of 7286 students were analysed finally. Overall, only 9.0% of the students participated in MVPA at least 60 minutes/day; 63.9% spent no more than 2 hours/day in sedentary behaviours. Frequent verbal encouragement and watching were associated with less leisure-time sedentary behaviours. The multivariate-adjusted odds ratios (ORs) for verbal encouragement and watching were 1.29 (95% CI, 1.08 to 1.55) and 1.19 (95% CI, 0.97 to 1.45) for 5-7 days per week. The involvement of family in the children's activity in most days of the week was associated with both higher level of MVPA and less leisure-time sedentary behaviours. The respective ORs among students who reported familial support 5-7 days per week, were 1.50 (95% CI, 1.21 to 1.86) for engaging in seven days of MVPA per week, 1.67 (95% CI, 1.19 to 2.32) for at least 60 minutes of MVPA daily, and 1.48 (95% CI, 1.19 to 1.84) for no more than 2 hours of leisure-time sedentary behaviours daily. This study found that less than 10.0% of urban Chinese adolescents engaged in MVPA at least 60 minutes/day. Family involving themselves in the children's activity exerted the most significant influence on children's behaviours

    Full Text Available Charcot-Marie-Tooth disease type 1A (CMT1A is caused by duplication of the peripheral myelin protein 22 (PMP22 gene on chromosome 17. It is the most common inherited demyelinating neuropathy. Type 2 diabetes mellitus is a common metabolic disorder that frequently causes predominantly sensory neuropathy. In this study, we report the occurrence of CMT1A in a Chinese family affected by type 2 diabetes mellitus. In this family, seven individuals had duplication of the PMP22 gene, although only four had clinical features of polyneuropathy. All CMT1A patients with a clinical phenotype also presented with type 2 diabetes mellitus. The other three individuals had no signs of CMT1A or type 2 diabetes mellitus. We believe that there may be a genetic link between these two diseases.

    The prevalence of adolescent smoking has been increasing rapidly in China. Expanding adolescent exposure to antismoking messages may be an effective approach to prevent tobacco use among this population. Using a cross-sectional sample of 8,444 high school students in four Chinese cities, this study assessed the relation between self-reported exposure to antismoking messages from families, schools, and mass media and the rate of past 30-day smoking and smoking intention among junior and senior high school students. Results from logistic regression suggested that antismoking messages delivered via school and media inhibited both tobacco use and the intention to smoke. The effects of familial warnings about harmful effects of smoking, in contrast, were at best insignificant.

    The double heterozygosity for α and β chain variants leads to the formation of abnormal heterodimer hybrids, which could render laboratory diagnostics in a routine setting difficult. The following is the first report of a double heterozygosity for Hb Q-Thailand [α74(EF3)Asp→His; HBA1: c.223G>C] with α + -thalassemia (α + -thal) and Hb J-Bangkok [β56(D7)Gly→Asp; HBB: c.170G>A] found in a Chinese family. Both subjects were healthy with normal or borderline hematological parameters. Hemoglobin (Hb) analyses showed a novel variant, Hb Q-Thailand and Hb J-Bangkok. Family studies helped in the initial recognition and in making presumptive diagnoses, but definitive diagnoses of these cases with complex α and β chain variants could only be obtained after DNA analysis.

    This study examined the relationship between perceived social change, parental control and family relations in a sample of 419 4th and 5th grade children and their mothers who are of Chinese descent but reside in three different contexts: Los Angeles (LA), Hong Kong (HK), and Beijing (BJ). HK mothers endorsed the highest levels of psychological control and the lowest levels of autonomy support compared to BJ and LA mothers. Perceived social change as measured by mothers' endorsement of new values and ideologies was associated with increased use of both autonomy support and psychological control. Results of the mediation analyses suggested that perceived social change explained differences between LA and HK mothers in autonomy support, but group differences in psychological control were magnified when perceived social change was accounted for. Finally, whereas autonomy support was associated with higher levels of child perceived acceptance in HK and LA, psychological control was associated with greater family conflict in BJ and LA. Findings suggested that as families undergo urbanization or social change, it may shift the implications of traditional strategies that are intended to socialize the child toward interpersonal attunement. Overall, the study highlights the importance of moving beyond ethnic-group or cross-national comparisons to investigate the role of changing social and economic contexts in understanding differences in the use of parental control and their associations with family relations.

    Full Text Available Attention deficit hyperactivity disorder (ADHD is one of the most common psychiatric disorders, affecting an estimated 5 to 12% of school-aged children worldwide. From 15 to 19 million Chinese children suffer from ADHD. The aim of this study was to investigate the association between family-environmental factors and ADHD in a sample of Chinese children.A pair-matched, case-control study was conducted with 161 ADHD children and 161 non-ADHD children of matching age and sex, all from 5-18 years of age. The ADHD subjects and the normal controls were all evaluated via structured diagnostic interviews. We examined the association between family-environmental factors and ADHD using the conditional multiple logistic regression with backward stepwise selection to predict the associated factors of ADHD.Having experienced emotional abuse and being a single child were both significant factors associated with children diagnosed with ADHD. ADHD subjects were more likely to have suffered from emotional abuse (OR = 11.09, 95% CI = 2.15-57.29, P = 0.004 and have been a single child in the family (OR = 6.32, 95% CI = 2.09-19.14, P = 0.001 when compared to normal controls. The results were not modified by other confounding factors.Our findings provide evidence that family-environmental factors are associated with ADHD among children in China. These findings, if confirmed by future research, may help to decrease ADHD by increasing the awareness of the effects of childhood emotional abuse.

    Osteogenesis imperfecta (OI) is a rare inherited disease characterized by increased bone fragility and vulnerability to fractures. Recently, WNT1 is identified as a new candidate gene for OI, here we detect pathogenic mutations in WNT1 and analyze the genotype-phenotype association in four Chinese families with OI. We designed a targeted next generation sequencing panel with known fourteen OI-related genes. We applied the approach to detect pathogenic mutations in OI patients and confirmed the mutations with Sanger sequencing and cosegregation analysis. Clinical fractures, bone mineral density (BMD) and the other clinical manifestations were evaluated. We also observed the effects of bisphosphonates in OI patients with WNT1 mutations. Four compound heterozygous mutations (c.110T>C; c.505 G>T; c. 385G>A; c.506 G>A) in WNT1 were detected in three unrelated families. These four mutations had not been reported yet. A recurrent homozygous mutation (c.506dupG) was identified in the other two families. These patients had moderate to severe OI, white to blue sclera, absence of dentinogenesis imperfecta and no brain malformation. We did not observe clear genotype-phenotype correlation in WNT1 mutated OI patients. Though bisphosphonates increased BMD in WNT1 related OI patients, height did not increase and fracture continued. We reported four novel heterozygous variants and confirmed a previous reported WNT1 mutation in four Chinese families with a clinical diagnosis of OI. Our study expanded OI spectrum and confirmed moderate to severe bone fragility induced by WNT1 defects. Copyright © 2016 Elsevier B.V. All rights reserved.

    Pediatric obesity has become a global public health problem. Data on the lifestyle behaviors, dietary habits, and familial factors of overweight and obese children and adolescents are limited. The present study aims to compare health-related factors among normal-weight, overweight, and obese Chinese children and adolescents. We conducted a cross-sectional study consisted of 4262 children and adolescents aged 5-18 years old from rural areas of the northeast China. Anthropometric measurements and self-reported information on health-related variables, such as physical activities, sleep duration, dietary habits, family income, and recognition of weight status from the views of both children and parents, were collected by trained personnel. The prevalence rates of overweight and obesity were 15.3 and 6.4%, respectively. Compared to girls, boys were more commonly overweight (17.5% vs. 12.9%) and obese (9.5% vs. 3.1%). Approximately half of the parents with an overweight or obese child reported that they failed to recognize their child's excess weight status, and 65% of patients with an overweight child reported that they would not take measures to decrease their child's body weight. Obese children and adolescents were more likely to be nonsnackers [odds ratio (OR): 1.348; 95% confidence interval (CI): 1.039-1.748] and to have a family income of 2000 CNY or more per month (OR: 1.442; 95% CI: 1.045-1.99) and less likely to sleep longer (≥7.5 h) (OR: 0.475; 95% CI: 0.31-0.728) than the normal-weight participants. Our study revealed a high prevalence of overweight and obesity in a large Chinese pediatric population. Differences in sleep duration, snacking, family income, and parental recognition of children's weight status among participants in different weight categories were observed, which should be considered when planning prevention and treatment programs for pediatric obesity.

    Waardenburg syndrome (WS) is a rare disease characterized by sensorineural deafness and pigment disturbance. To date, almost 100 mutations have been reported, but few reports on cases with SOX10 gene deletion. The inheritance pattern of SOX10 gene deletion is still unclear. Our objective was to identify the genetic causes of Waardenburg syndrome type II in a two-generation Chinese family. Clinical evaluations were conducted in both of the patients. Microarray analysis and multiplex ligation-dependent probe amplification (MLPA) were performed to identify disease-related copy number variants (CNVs). DNA sequencing of the SOX10, MITF and SNAI2 genes was performed to identify the pathogenic mutation responsible for WS2. A 280kb heterozygous deletion at the 22q13.1 chromosome region (including SOX10) was detected in both of the patients. No mutation was found in the patients, unaffected family members and 30 unrelated healthy controls. This report is the first to describe SOX10 heterozygous deletions in Chinese WS2 patients. Our result conform the thesis that heterozygous deletions at SOX10 is an important pathogenicity for WS, and present as autosomal dominant inheritance. Nevertheless, heterozygous deletion of the SOX10 gene would be worth investigating to understand their functions and contributions to neurologic phenotypes. Copyright © 2015 Elsevier Ireland Ltd.

    Full Text Available Abstract Anophthalmia is a rare eye development anomaly resulting in absent ocular globes or tissue in the orbit since birth. Here, we investigated a newborn with bilateral anophthalmia in a Chinese family. Exome sequencing revealed that compound heterozygous mutations c.287G > A (p.(Arg96His and c.709G > A (p.(Gly237Arg of the ALDH1A3 gene were present in the affected newborn. Both mutations were absent in all of the searched databases, including 10,000 in-house Chinese exome sequences, and these mutations were confirmed as having been transmitted from the parents. Comparative amino acid sequence analysis across distantly related species revealed that the residues at positions 96 and 234 were evolutionarily highly conserved. In silico analysis predicted these changes to be damaging, and in vitro expression analysis revealed that the mutated alleles were associated with decreased protein production and impaired tetrameric protein formation. This study firstly reported that compound heterozygous mutations of the ALDH1A3 gene can result in anophthalmia in humans, thus highlighting those heterozygous mutations in ALDH1A3 should be considered for molecular screening in anophthalmia, particularly in cases from families without consanguineous relationships.

    Background Individuals with early-onset depression may be a clinically distinct group with particular symptom patterns, illness course, comorbidity and family history. This question has not been previously investigated in a Han Chinese population. Methods We examined the clinical features of 1970 Han Chinese women with DSM-IV major depressive disorder (MDD) between 30 and 60 years of age across China. Analysis of linear, logistic and multiple logistic regression models was used to determine the association between age at onset (AAO) with continuous, binary and discrete characteristic clinical features of MDD. Results Earlier AAO was associated with more suicidal ideation and attempts and higher neuroticism, but fewer sleep, appetite and weight changes. Patients with an earlier AAO were more likely to suffer a chronic course (longer illness duration, more MDD episodes and longer index episode), increased rates of MDD in their parents and a lower likelihood of marriage. They tend to have higher comorbidity with anxiety disorders (general anxiety disorder, social phobia and agoraphobia) and dysthymia. Conclusions Early AAO in MDD may be an index of a more severe, highly comorbid and familial disorder. Our findings indicate that the features of MDD in China are similar to those reported elsewhere in the world. PMID:21782247

    Nuclear receptors (NRs) are major pharmacological targets that allow an access to the mechanisms controlling gene regulation. As such, some NRs were identified as biological targets of active compounds contained in herbal remedies found in traditional medicines. We aim here to review this expanding literature by focusing on the informative articles regarding the mechanisms of action of traditional Chinese medicines (TCMs). We exemplified well-characterized TCM action mediated by NR such as steroid receptors (ER, GR, AR), metabolic receptors (PPAR, LXR, FXR, PXR, CAR) and RXR. We also provided, when possible, examples from other traditional medicines. From these, we draw a parallel between TCMs and phytoestrogens or endocrine disrupting chemicals also acting via NR. We define common principle of action and highlight the potential and limits of those compounds. TCMs, by finely tuning physiological reactions in positive and negative manners, could act, in a subtle but efficient way, on NR sensors and their transcriptional network.

    To describe the clinical and genetic findings in one Chinese family with juvenile-onset open angle glaucoma (JOAG). One family was examined clinically and a follow-up took place 5 years later. After informed consent was obtained, genomic DNA was extracted from the venous blood of all participants. Linkage analysis was performed with three microsatellite markers around the MYOC gene (D1S196, D1S2815, and D1S218) in the family. Mutation screening of all coding exons of MYOC was performed by direct sequencing of PCR-amplified DNA fragments and restriction fragment length polymorphism (RFLP) analysis. Bioinformatics analysis by the Garnier-Osguthorpe-Robson (GOR) method predicted the effects of variants detected on secondary structures of the MYOC protein. Clinical examination and pedigree analysis revealed a three- generation family with seven members diagnosed with JOAG, three with ocular hypertension, and five normal individuals. Through genotyping, the pedigree showed a linkage to the MYOC on chromosome 1q24-25. Mutation screening of MYOC in this family revealed an A-->T transition at position 1348 (p. N450Y) of the cDNA sequence. This missense mutation co-segregated with the disease phenotype of the family, but was not found in 100 normal controls. Secondary structure prediction of the p.N450Y by the GOR method revealed the replacement of a coil with a beta sheet at the amino acid 447. Early onset JOAG, with incomplete penetrance, is consistent with a novel mutation in MYOC. The finding provides pre-symptomatic molecular diagnosis for the members of this family and is useful for further genetic consultation.

    Breast cancer is the most frequent female malignancy worldwide. Among them, some cases have hereditary susceptibility in two leading genes, BRCA1 and BRCA2. Heterozygous germ line mutations in them are related with increased risk of breast, ovarian and other cancer, following autosomal dominant inheritance mode. For purpose of early finding, early diagnosis and early treatment, mutation detecting of BRCA1/2 genes was performed in unselected 300 breast or ovarian patients and unaffected women using next-generation sequencing and then confirmed by Sanger sequencing. A non-previously reported heterozygous mutation c.8946_8947delAG (p.D2983FfsX34) of BRCA2 gene was identified in an unaffected Chinese woman with family history of breast cancer (her breast cancer mother, also carrying this mutation). The BRCA2-truncated protein resulted from the frame shift mutation was found to lose two putative nuclear localization signals and a Rad51-binding motif in the extreme C-terminal region by bioinformatic prediction. And then in vitro experiments showed that nearly all the mutant protein was unable to translocate to the nucleus to perform DNA repair activity. This novel mutant BRCA2 protein is dysfunction. We classify the mutation into disease causing and conclude that it is the risk factor for breast cancer in this family. So, conducting the same mutation test and providing genetic counseling for this family is practically meaningful and significant. Meanwhile, the identification of this new mutation enriches the Breast Cancer Information Core database, especially in China.

    The inhibitory IκB family of proteins is subdivided into two groups based on protein localization in the cytoplasm or in the nucleus. These proteins interact with NF-κB, a major transcription factor regulating the expression of many inflammatory cytokines, by modulating its transcriptional activity. However, nuclear IκB family proteins not only interact with NF-κB to change its transcriptional activity, but they also bind to chromatin and control gene expression. This review provides an overview of nuclear IκB family proteins and their role in immune homeostasis. Copyright © 2015 Elsevier B.V. All rights reserved.

    With China's rapid economic growth in the past few decades, there is currently an emerging focus on happiness. Cross-cultural validity studies have indicated that the four-item Subjective Happiness Scale (SHS) has high internal consistency and stable reliability. However, the psychometric characteristics of the SHS in broader Chinese community samples are unknown. We evaluated the factor structure and psychometric properties of the SHS in the Hong Kong general population. The Chinese SHS was derived using forward-backward translation. Of the Cantonese-speaking participants aged ≥15 years, 2,635 were randomly selected from the random sample component of the FAMILY Cohort, a territory-wide cohort study in Hong Kong. In addition to the SHS, a single-item overall happiness scale, the Patient Health Questionnaire-9 (PHQ-9), the Family Adaptation, Partnership, Growth, Affection, Resolve (APGAR) scale, and the Medical Outcomes Study 12-item short-form version 2 (SF-12) mental and physical health scales were administered. Exploratory and confirmatory factor analyses supported a single factor with high loadings for the four SHS items. Multiple group analyses indicated factor invariance across sex and age groups. Cronbach's alpha was 0.82, and 2-week test-retest reliability (n = 191) was 0.70. The SHS correlated significantly with single-item overall happiness (Spearman's rho [ρ] = 0.57), Family APGAR (ρ = 0.26), PHQ-9 (ρ = -0.34), and mental health-related quality of life (ρ = 0.40) but showed a lower correlation with physical health (ρ = 0.15). A regression model that included the PHQ-9 and Family APGAR scores explained 37% of the variance in SF-12 mental health scores; adding the SHS raised the variance explained to 41 %. Our results support the reliability and validity of the SHS as a relevant component in the measurement battery for mental well-being in a Chinese general population.

    To identify the disease-causing mutation(s) in a Chinese family with autosomal recessive Usher syndrome type 1 (USH1). An ophthalmic examination and an audiometric test were conducted to ascertain the phenotype of two affected siblings. The microsatellite marker D11S937, which is close to the candidate gene MYO7A (USH1B locus), was selected for genotyping. From the DNA of the proband, all coding exons and exon-intron boundaries of MYO7A were sequenced to identify the disease-causing mutation(s). Restriction fragment length polymorphism (RFLP) analysis was performed to exclude the alternative conclusion that the mutations are non-pathogenic rare polymorphisms. Based on severe hearing impairment, unintelligible speech, and retinitis pigmentosa, a clinical diagnosis of Usher syndrome type 1 was made. The genotyping results did not exclude the USH1B locus, which suggested that the MYO7A gene was likely the gene associated with the disease-causing mutation(s) in the family. With direct DNA sequencing of MYO7A, two novel compound heterozygous mutations (c.3742G>A and c.6051+1G>A) of MYO7A were identified in the proband. DNA sequence analysis and RFLP analysis of other family members showed that the mutations cosegregated with the disease. Unaffected members, including the parents, uncle, and sister of the proband, carry only one of the two mutations. The mutations were not present in the controls (100 normal Chinese subjects=200 chromosomes) according to the RFLP analysis. In this study, we identified two novel mutations, c.3742G>A (p.E1248K) and c.6051+1G>A (donor splice site mutation in intron 44), of MYO7A in a Chinese non-consanguineous family with USH1. The mutations cosegregated with the disease and most likely cause the phenotype in the two affected siblings who carry these mutations compound heterozygously. Our finding expands the mutational spectrum of MYO7A.

    The purpose of this study was to identify the genetic causes of a family presenting with multiple symptoms overlapping Usher syndrome type II (USH2) and Waardenburg syndrome type IV (WS4). Targeted next-generation sequencing including the exon and flanking intron sequences of 79 deafness genes was performed on the proband. Co-segregation of the disease phenotype and the detected variants were confirmed in all family members by PCR amplification and Sanger sequencing. The affected members of this family had two different recessive disorders, USH2 and WS4. By targeted next-generation sequencing, we identified that USH2 was caused by a novel missense mutation, p.V4907D in GPR98; whereas WS4 due to p.V185M in EDNRB. This is the first report of homozygous p.V185M mutation in EDNRB in patient with WS4. This study reported a Chinese family with multiple independent and overlapping phenotypes. In condition, molecular level analysis was efficient to identify the causative variant p.V4907D in GPR98 and p.V185M in EDNRB, also was helpful to confirm the clinical diagnosis of USH2 and WS4.

    Full Text Available Autosomal dominant adult-onset demyelinating leukodystrophy (ADLD is a very rare neurological disorder featured with late onset, slowly progressive central nervous system demyelination. Duplication or over expression of the lamin B1 (LMNB1 gene causes ADLD. In this study, we undertook a comprehensive clinical evaluation and genetic detection for a Chinese family with ADLD. The proband is a 52-year old man manifested with autonomic abnormalities, pyramidal tract dysfunction. MRI brain scan identified bilateral symmetric white matter (WM hyper-intensities in periventricular and semi-oval WM, cerebral peduncles and middle cerebellar peduncles. The proband has a positive autosomal dominant family history with similar clinical manifestations with a trend of genetic anticipation. In order to understand the genetic cause of the disease in this family, target exome capture based next generation sequencing has been done, but no causative variants or possibly pathogenic variants has been identified. However, Multiplex ligand-dependent probe amplification (MLPA showed whole duplication of LMNB1 gene which is co-segregated with the disease phenotype in this family. This is the first genetically confirmed LMNB1 associated ADLD pedigree from China.

    Full Text Available BACKGROUND: Filaggrin gene (FLG mutations have been identified as the cause of ichthyosis vulgaris (IV and major predisposing factors for atopic dermatitis (AD. The relationship among AD, IV and FLG mutations has not been clarified yet. Mutations 3321delA and K4671X, two of the most common mutations in Chinese patients, were both statistically associated with AD in case-control studies. MATERIALS AND METHODS: A group of 100 family trios (a total of 300 members with one affected AD proband and both parents were recruited and screened for three filaggrin null mutations (3222del4, 3321delA and K4671X. The subjects' manifestations of AD and IV were assessed by two experienced dermatologists and recorded in detail. The relationship of common mutations to AD were assessed using both case-control and family-based tests of association. Filaggrin expression was measured in skin of 3 subjects with K4671X heterozygote and the normal control using quantitative real-time RT-PCR and immunohistochemistry. RESULTS: Of 100 probands for AD, 22 were carriers for common FLG mutations and only 2 of them were from 40 none-IV family trios (5.00%, consistent with that of the healthy control group (3.99%, P>0.05. Significant statistical associations were revealed between AD and 3321delA (P<0.001, odds ratio 12.28, 95% confidence interval 3.35-44.98 as well as K4671X (P = 0.002, odds ratio 4.53, 95% confidence interval 1.77-11.60. The family-based approach revealed that 3321delA was over-transmitted to AD offspring from parents (T:U = 12∶1, P = 0.003 but failed to demonstrate transmission disequilibrium between K4671X and AD (T:U = 10∶8, P = 0.815. Moreover, compared to the normal control, filaggrin expression at both mRNA and protein levels in epidermis of subjects with K4671X(heter was not reduced. CONCLUSIONS: AD patients from none-IV family trios have low probability of carrying FLG mutations. The present family samples confirmed the

    To identify whether benefit finding is a mediator or moderator in the relationship between caregiver burden and psychological well-being (anxiety and depression) in Chinese family caregivers of community-dwelling stroke survivors. Family caregivers not only bear a heavy burden, a high level of anxiety and depression, but also experience benefit finding (positive effects result from stressful events). However, the relationships among benefit finding, caregiver burden and psychological well-being in Chinese family caregivers are not well known. This study was a cross-sectional correlational design. Caregivers (n = 145) of stroke survivors were recruited from two communities in Zhengzhou, China. Data were collected by face-to-face interviews with structured questionnaires, examining caregiver burden, benefit finding and psychological well-being of caregivers. A hierarchical regression analysis explored whether caregiver burden and benefit finding were associated with anxiety and depression of caregivers. The moderator role of benefit finding was examined by testing the significance of the interaction between caregiver burden and benefit finding. A mediational model was used to test benefit finding as a mediator between caregiver burden and psychological well-being of caregivers using process in spss 21.0. Caregiver burden and benefit finding were significantly associated with both anxiety and depression of caregivers. Benefit finding did not portray a moderating role, but portrayed the mediator role in the relationship between caregiver burden, anxiety and depression in caregivers. This study provides the preliminary evidence to nurses that intervention focus on benefit finding may help improve the psychological well-being of caregivers. This study offers nurses rational for assessing caregiver's negative emotions and benefit finding. By targeting benefit finding, the nurse may guide caregivers in benefit identification and implement interventions to reduce anxiety

    As a common mental disorder, depressive symptoms had been studied extensively all over the world. However, positive resources for combating depressive symptoms among Chinese doctors were rarely studied. Our study aimed to investigate the relationships between work-family conflict (WFC) and family-work conflict (FWC) with depressive symptoms among Chinese doctors. Meanwhile, the role of perceived organizational support (POS) in this association was explored at an organizational level. The investigation was conducted between March and April 2014. Questionnaires that measured WFC, FWC, depressive symptoms and POS were distributed to 1200 doctors in Shenyang, China. The final study subjects were 931 doctors (effective response rate: 77.6%). In all analyses, male and female doctors were analyzed separately because of possible gender differences. Hierarchical linear regression analyses were used to examine the moderating role of POS. Baron and Kenny's technique and asymptotic and resampling strategies were used to explore the mediating role of POS on the associations of WFC or FWC with depressive symptoms. WFC and FWC had positive relations with depressive symptoms among doctors. POS played a partial mediating role on the correlation of FWC with depressive symptoms among male doctors, and POS played a partial mediating role on the correlation of WFC with depressive symptoms among female doctors. POS had a positive moderating effect on the relationship between WFC and depressive symptoms among doctors. WFC and FWC could aggravate doctors' depressive symptoms, and POS, as an organizational resource, could fight against doctors' depressive symptoms. When POS functioned as a mediator, FWC had a negative effect on POS, which could increase male doctors' depressive symptoms, and WFC had a negative effect on POS, which could increase female doctors' depressive symptoms. In the meantime, POS, as a moderator, could enhance the effects of WFC on depressive symptoms.

    This study aimed to understand the dyadic relationships between family communication and quality of life (QOL) and between coping and QOL in Chinese-American and Korean-American breast cancer survivor (BCS)-family member dyads. A cross-sectional survey design was used. A total of 32 Chinese-American and Korean-American BCS-family member dyads were recruited from the California Cancer Surveillance Program and area hospitals in Los Angeles County, California, USA. The dyadic data were analyzed using a pooled regression actor-partner interdependence model. The study findings demonstrated that the survivors' general communication and use of reframing coping positively predicted their own QOL. The survivors' and family members' general communication was also a strong predictor of the family members' physical-related QOL score specifically. Meanwhile, each person's use of mobilizing coping negatively predicted his or her partner's QOL. The study findings add important information to the scarce literature on the QOL of Asian-American survivors of breast cancer. The findings suggest that Chinese-American and Korean-American BCS and their family members may benefit from interventions that enhance communication and coping within the family unit.

    Protein disulfide isomerase (PDI) family members are specific endoplasmic reticulum proteins that are involved in the pathogenesis of numerous diseases including neurodegenerative diseases, cancer and obesity. However, the metabolic effects of PDIA4 remain unclear in humans. The aims of this study were to investigate the associations of serum PDIA4 with the metabolic syndrome (MetS) and its components in Chinese adults. A total of 669 adults (399 men and 270 women) were recruited. Serum PDIA4 concentrations and biochemical variables were recorded. Insulin sensitivity and β-cell function were examined by homeostasis model assessment. MetS was defined based on the modified National Cholesterol Education Program Adult Treatment Panel III criteria for Asia Pacific. The participants with MetS had significantly higher serum PDIA4 levels than those without MetS (Pmetabolic syndrome were 67 and 72%, respectively, in male patients and 60 and 78%, respectively, in female patients. Finally, the result showed that PDIA4 had a significantly higher area under the curve compared with blood pressure to detect MetS using receiver operating characteristic analysis. Serum PDIA4 concentrations are closely associated to MetS and its components in Chinese adults.

    The present study examined 2 measures of Chinese American immigrant parents' emotional expression in the family context: self-reported emotional expressivity and observed emotional expression during a parent-child interaction task. Path analyses were conducted to examine the concurrent associations between measures of emotional expression and (a) parents' American and Chinese cultural orientations in language proficiency, media use, and social affiliation domains, and (b) parents' and teachers' ratings of children's emotion-related regulation. Results suggested that cultural orientations were primarily associated with parents' self-reported expressivity (rather than observed emotional expression), such that higher American orientations were generally associated with higher expressivity. Although parents' self-reported expressivity was only related to their own reports of children's regulation, parents' observed emotional expression was related to both parents' and teachers' reports of children's regulation. These results suggest that self-reported expressivity and observed emotional expression reflect different constructs and have differential relations to parents' cultural orientations and children's regulation.

    Full Text Available AIM: To identify the mutations of MYOC, OPTN, CYP1B1 and WDR36 in a large Chinese family affected by juvenile open angle glaucoma (JOAG. METHODS: Of 114 members of one family were recruited in this study. Blood samples from twelve members of this pedigree were collected for further research. As a control, 100 unrelated subjects were recruited from the same hospital. The exon and flanking intron sequences of candidate genes were amplified using the polymerase chain reaction and direct DNA sequencing. RESULTS: The proband (III:10 was a seventy-three years old woman with binocular JOAG at the age of 31. A recurrent heterozygous mutation (c.1099G>A of MYOC was identified in the three JOAG patients and another suspect. This transition was located in the first base pair of codon 367 (GGA>AGA in exon 3 of MYOC and was predicted to be a missense substitution of glycine to arginine (p.G367R in myocilin. Mutations in OPTN, CYP1B1 or WDR36 were not detected in this study. The G367R mutation was not present in unaffected family members or in 100 ethnically matched controls. Other variants of the coding regions of candidate genes were not detected in all participants. To date, this family was the largest to have been identified as carrying a certain MYOC mutation in China, further evidence of a founder effect for the G367R MYOC mutant was provided by our data. CONCLUSION: A MYOC c.1099G>A mutation in an autosomal dominant JOAG family is identified and the characteristic phenotypes among the patients are summarized. Genetic testing could be utilized in high-risk populations and be helpful not only for genetic counseling, but also for early diagnosis and treatment of affected patients or carriers of inherited JOAG.

    Usher syndrome is an autosomal recessive disease characterized by sensorineural hearing loss, age-dependent retinitis pigmentosa (RP), and occasionally vestibular dysfunction. The most severe form is Usher syndrome type 1 (USH1). Mutations in the MYO7A gene are responsible for USH1 and account for 29-55% of USH1 cases. Here, we characterized a Chinese family (no. 7162) with USH1. Combining the targeted capture of 131 known deafness genes, next-generation sequencing, and bioinformatic analysis, we identified two deleterious compound heterozygous mutations in the MYO7A gene: a reported missense mutation c.73G>A (p.G25R) and a novel nonsense mutation c.462C>A (p.C154X). The two compound variants are absent in 219 ethnicity-matched controls, co-segregates with the USH clinical phenotypes, including hearing loss, vestibular dysfunction, and age-dependent penetrance of progressive RP, in family 7162. Therefore, we concluded that the USH1 in this family was caused by compound heterozygous mutations in MYO7A.

    To describe the clinical and genetic findings in a Chinese family with three sibs diagnosed with Usher syndrome type IIC. Four members received ophthalmic and otologic tests to ascertain the clinical characteristics. According to the clinical phenotype, we focused attention on a total of 658 genes associated with them. We screened the possible pathogenic mutation sites, used Sanger to exclude the false positive and verified whether there were co-segregated among the family members. Typical fundus features found in the proband supported the diagnosis of retinitis pigmentosa (RP). Audiometric test indicated moderate to severe sensorineural hearing impairment while the vestibular function was normal. Whole-exome sequencing identified the presence of two novel compound heterozygous mutations in ADGRV1, a known gene responsible for Usher syndrome type IIC. Mutationc.15008delG/p.Gly5003AlafsTer13 was inherited from the mother while c.18383_18386dupACAG/p.His6130GlnfsTer84 was inherited from the father, and they were co-segregated with the disease phenotype in the family. The mutations found in our study not only broaden the mutation spectrum of ADGRV1, but also provide assistances for future genetic diagnosis and treatment for Usher syndrome patients.

Using a longitudinal sample of Chinese immigrant families, the authors of the current study examined how unsupportive parenting and parent-child sense of alienation sequentially mediate the relationship between parent-child acculturation discrepancy and child adjustment during early and middle adolescence. Acculturation discrepancy scores were created using multilevel modeling to take into account the interdependence among family members. Structural equation models showed that during early adolescence, parent-child American orientation discrepancy is related to parents' use of unsupportive parenting practices; parents' use of unsupportive parenting is related to increased sense of alienation between parents and children, which in turn is related to more depressive symptoms and lower academic performance in Chinese American adolescents. These patterns of negative adjustment established in early adolescence persist into middle adolescence. This mediating effect is more apparent among father-adolescent dyads than among mother-adolescent dyads. In contrast, parent-child Chinese orientation discrepancy does not demonstrate a significant direct or indirect effect on adolescent adjustment, either concurrently or longitudinally. The current findings suggest that during early adolescence, children are more susceptible to the negative effects of parent-child acculturation discrepancy; they also underscore the importance of fathering in Chinese immigrant families.

    Nuclear medicine technologists is an important part of nuclear medicine professionals, and play an important role in the progress of nuclear medicine. The professional quality of nuclear medicine technologists must adapt to the development of nuclear medicine. There is a relatively great gap between China mainland and developed countries in the field of nuclear medicine. In future, it is urgent to improve the professional quality and the educational level of nuclear medicine technologists

    We aimed to investigate the genetic causes of hearing loss in a Chinese proband with autosomal recessive congenital deafness. The targeted capture of 159 known deafness genes and next-generation sequencing were performed to study the genetic causes of hearing loss in the Chinese family. Sanger sequencing was employed to verify the variant mutations in members of this family. The proband harbored two mutations in the MYO7A gene in the form of compound heterozygosity. She was found to be heterozygous for a novel insertion mutation c.3847_3848 ins TCTG (p.N1285LfsX24) in exon 30 and for the known mutation c.2239_2240delAG (p.R747S fsX16)in exon 19. The novel mutation was absent in the 1000 Genomes Project. These variants were carried in the heterozygous state by the parents and were therefore co-segregated with the genetic disease. Clinical re-assessment, including detailed audiologic and ocular examinations, revealed congenital deafness and retinitis pigmentosa in the proband. Collectively, the combination of audiometric, ophthalmologic and genetic examinations successfully confirmed the phenotype of Usher syndrome type 1 (USH1). This study demonstrates that the novel mutation c.3847_3848insTCTG (p. N1285LfsX24) in compound heterozygosity with c.2239_2240delAG in the MYO7A gene is the main cause of USH1 in the proband. Our study expands the mutational spectrum of MYO7A and provides a foundation for further investigations elucidating the MYO7A-related mechanisms of USH1. Copyright © 2017 Elsevier B.V.

    Phospholipids play important roles in nuclear function as dynamic building blocks for the biogenesis of the nuclear membrane, as well as signals by which the nucleus communicates with other organelles, and regulate a variety of nuclear events. The mechanisms underlying the nuclear roles of phospholipids remain poorly understood. Lipins represent a family of phosphatidic acid (PA) phosphatases that are conserved from yeasts to humans and perform essential functions in lipid metabolism. Several studies have identified key roles for lipins and their regulators in nuclear envelope organization, gene expression and the maintenance of lipid homeostasis in yeast and metazoans. This review discusses recent advances in understanding the roles of lipins in nuclear structure and function.

    To investigate the genetic findings and phenotypic characteristics of a Chinese family with Norrie disease (ND). Molecular genetic analysis and clinical examinations were performed on a Chinese family with ND. Mutations in the Norrie disease pseudoglioma (NDP) gene were detected by direct sequencing. Haplotypes were constructed and compared with the phenotypes in the family. Evolutionary comparisons and mutant open reading frame (ORF) prediction were also undertaken. Two family members with ocular manifestations were diagnosed with ND. No signs of sensorineural hearing loss were observed in either patient, while one of them showed signs of mild mental retardation. A novel heterozygous mutation in the NDP gene, c.-1_2delAAT, was detected in both patients. The mutation and the mutation bearing haplotype co-segregated with the ND phenotype in males and was transmitted from their mothers and/or grandmothers (II:2). The male without ND did not harbor the mutation. The mutation occurred at the highly conserved nucleotides. ORF finder predicted that the mutation would lead to the production of a truncated protein that lacks the first 11 N-terminal amino acids. A novel mutation, c.-1_2delAAT in the NDP gene, was identified in a Chinese family with ND. This mutation caused ND without obvious sensorineural hearing loss. Mental disorder was found in one but not the other patients. The clinical heterogeneity in the family indicated that other genetic variants and epigenetic factors may also play a role in the disease presentation.

  18. Family-Concentrated Ownership in Chinese PLCs: Does Ownership Concentration Always Enhance Corporate Value?

    Full Text Available In this paper we investigate the relationship between family ownership structure and corporate value across a sample of 1314 firm-year observations of China’s family publicly listed companies (PLCs, from 2004 to 2008. We find a significant inverse-U-shaped relationship between the controlling family’s ultimate cash-flow rights and corporate value; as measured by Tobin’s Q. That is, as family-ownership concentration increases, corporate value first increases and then decreases. This finding refreshes our understanding of the relationship between family-ownership concentration and corporate value in emerging economies such as found in China. We corroborate prior findings that when controlling families hold excess control over cash-flow rights, corporate value is significantly lowered, while multiple large shareholders structure is significantly associated with higher corporate value. In addition; board independence is found to significantly improve corporate value in the context of family-concentrated ownership. We also test for potential endogeneity between family ownership and corporate value and find our results to be robust.

    The sustained increase in their use of social networking facilitates the development of adolescents but comes with the risk of cyberbullying, which creates new challenges in regard to adolescent protection. Past evidence shows that family victimization may play an essential role in the way adolescents learn cyberbullying behaviors. Yet, research on the co-occurrence of family victimization and cyberbullying is limited. This study aims to investigate the associations between cyberbullying and family victimization among adolescents, and to examine the health correlates of cyberbullying and family poly-victimization. A large sample of 18,341 students, aged 15-17, from six cities in China, collected between 2009 and 2010 is employed in the present study, which investigated the association between various kinds of family victimization and adolescent cyberbullying. Data analysis was conducted in 2017. In-law conflict, intimate partner violence, elder abuse and neglect, and child maltreatment were associated with a higher possibility of children becoming internet victims. Parents' divorce and separation, low family income, mother's low level of education, and father's unemployment were all associated with cyberbullying victimization. Cyber victimization was positively correlated to symptoms of PTSD and depression, self-harm, and other physical and mental health variables. Possible explanations for the relationships found in this study are discussed and implications for future research and services are provided. Proactive screening for family poly-victimization and cyberbullying is suggested. Schools are highly recommended to cooperate with parents to promote cyber safety. Copyright © 2018 Elsevier Ltd.

    The product design course for industrial design students was implemented in our university which spans 9 weeks. Throughout the creativity rules and field study, students achieve high standard on problem identification and concept generation. The prototype test with elderly in design projects is helpful to make students with deeper understand user demand, which in turn enhance the concept further. Traditional Chinese checkers are redesigned using special checkers with different height or shape and specific rules to increase user interest and game diversity. Game is more challenging due to location weighting on score calculation to planning its strategies. Redesign Chinese checkers game board include reconfigurable board and several shape checkers. Checkers has 3 parts: standing ring body, the base body, both support the side holding structure. The body shows slightly concave to facilitate the fingers hold. The upper portion of the body is provided with different shapes extension section which can be engaged with base body. Player move the checker to the opposite target area. When one of player moved all the checkers to the opposite target area; they shift to the scoring calculation stage. The participant may develop specific strategy to gain higher score by maximized weighted checkers into its target block regions.

    Twenty-four individuals were investigated that spanned six generations in a Chinese family affected with an apparently autosomal dominant form of dentinogenesis imperfecta type II (DGI-II, OMIM 125490). All affected individuals presented with typical, clinical and radiographic features of DGI-II, but without bilateral progressive high-frequency sensorineural hearing loss. To investigate the mutated molecule, a positional candidate approach was used to determine the mutated gene in this family. Genomic DNA was obtained from 24 affected individuals, 18 unaffected relatives of the family and 50 controls. Haplotype analysis was performed using leukocyte DNA for 6 short tandem repeat (STR) markers present in chromosome 4 (D4S1534, GATA62A11, DSPP, DMP1, SPP1 and D4S1563). In the critical region between D4S1534 and DMP1, the dentin sialophosphoprotein (DSPP) gene (OMIM *125485) was considered as the strongest candidate gene. The first four exons and exon/intron boundaries of the gene were analyzed using DNA from 24 affected individuals and 18 unaffected relatives of the same family. DNA sequencing revealed a heterozygous deletion mutation in intron 2 (at positions -3 to -25), which resulted in a frameshift mutation, that changed the acceptor site sequence from CAG to AAG (IVS2-3C→A) and may also have disrupted the branch point consensus sequence in intron 2. The mutation was found in the 24 affected individuals, but not in the 18 unaffected relatives and 50 controls. The deletion was identified by allele-specific sequencing and denaturing high-performance liquid chromatography (DHPLC) analysis. We conclude that the heterozygous deletion mutation contributed to the pathogenesis of DGI-II

    Congenital central hypoventilation syndrome (CCHS) is characterized by compromised chemoreflexes resulting in sleep hypoventilation. We report a Chinese family with paired-like homeobox 2B (PHOX2B) mutation-confirmed CCHS, with a clinical spectrum from newborn to adulthood, to increase awareness of its various manifestations. After identifying central hypoventilation in an adult man (index case), clinical evaluation was performed on the complete family, which consisted of the parents, five siblings, and five offspring. Pulmonary function tests, overnight polysomnography, arterial blood gas measurements, hypercapnia ventilatory response, and PHOX2B gene mutation screening were performed on living family members. Brain MRI, 24-h Holter monitoring, and echocardiography were performed on members with clinically diagnosed central hypoventilation. The index patient and four offspring manifested clinical features of central hypoventilation. The index patients had hypoxia and hypercapnia while awake, polycythemia, and hematocrit levels of 70%. The first and fourth children had frequent cyanotic spells, and both died of respiratory failure. The second and third children remained asymptomatic until adulthood, when they experienced impaired hypercapnic ventilatory response. The third child had nocturnal hypoventilation with nadir pulse oximetric saturation of 59%. Adult-onset CCHS with PHOX2B gene mutation of the + 5 alanine expansions were confirmed in the index patient and the second and third children. The index patient and the third child received ventilator support system bilevel positive airway pressure treatment, which improved the hypoxemia, hypercapnia, and polycythemia without altering their chemosensitivity. Transmission of late-onset CCHS is autosomal-dominant. Genetic screening of family members of CCHS probands allows for early diagnosis and treatment.

    To describe the clinical and genetic findings in one Chinese family with autosomal recessive retinitis pigmentosa (arRP) and in three unrelated Chinese families with Usher syndrome type II (USH2). One family (FR1) with arRP and three unrelated families (F6, F7, and F8) with Usher syndrome (USH), including eight affected members and seven unaffected family individuals were examined clinically. The study included 100 normal Chinese individuals as normal controls. After obtaining informed consent, peripheral blood samples from all participants were collected and genomic DNA was extracted. Genotyping and haplotyping analyses were performed on the known genetic loci for arRP with a panel of polymorphic markers in family FR1. In all four families, the coding region (exons 2-72), including the intron-exon boundary of the USH2A (Usher syndrome type -2A protein) gene, was screened by PCR and direct DNA sequencing. Whenever substitutions were identified in a patient, a restriction fragment length polymorphism (RFLP) analysis, single strand conformation polymorphism (SSCP) analysis, or high resolution melt curve analysis (HRM) was performed on all available family members and on the 100 normal controls. The affected individuals presented with typical fundus features of retinitis pigmentosa (RP), including narrowing of the vessels, bone-spicule pigmentation, and waxy optic discs. The electroretinogram (ERG) wave amplitudes of the available probands were undetectable. Audiometric tests in the affected individuals in family FR1 were normal, while indicating moderate to severe sensorineural hearing impairment in the affected individuals in families F6, F7, and F8. Vestibular function was normal in all patients from all four families. The disease-causing gene in family FR1 was mapped to the USH2A locus on chromosome 1q41. Seven novel mutations (two missenses, one 7-bp deletion, two small deletions, and two nonsenses) were detected in the four families after sequencing analysis of

    We report here the clinical, genetic and molecular characterization of one three-generation Han Chinese family with Leber's hereditary optic neuropathy (LHON) and hearing loss. Four of 14 matrilineal relatives exhibited the moderate central vision loss at the average age of 12.5 years. Of these, one subject exhibited both LHON and mild hearing impairment. Sequence analysis of the complete mitochondrial genomes in the pedigree showed the presence of homoplasmic LHON-associated ND6 T14484C mutation, deafness-associated 12S rRNA A1555 mutation and 47 other variants belonging to Eastern Asian haplogroup H2. None of other mitochondrial variants was evolutionarily conserved and functional significance. Therefore, the coexistence of the A1555G mutation and T14484C mutations in this Chinese family indicate that the A1555G mutation may play a synergistic role in the phenotypic manifestation of LHON associated ND6 T14484C mutation. However, the incomplete penetrance of vision and hearing loss suggests the involvement of nuclear modifier genes and environmental factors in the phenotypic expression of these mtDNA mutations

    An enhanced air dispersion modelling scheme is proposed to cope with the building layout and complex terrain of a typical Chinese nuclear power plant (NPP) site. In this modelling, the California Meteorological Model (CALMET) and the Stationary Wind Fit and Turbulence (SWIFT) are coupled with the Risø Mesoscale PUFF model (RIMPUFF) for refined wind field calculation. The near-field diffusion coefficient correction scheme of the Atmospheric Relative Concentrations in the Building Wakes Computer Code (ARCON96) is adopted to characterize dispersion in building arrays. The proposed method is evaluated by a wind tunnel experiment that replicates the typical Chinese NPP site. For both wind speed/direction and air concentration, the enhanced modelling predictions agree well with the observations. The fraction of the predictions within a factor of 2 and 5 of observations exceeds 55% and 82% respectively in the building area and the complex terrain area. This demonstrates the feasibility of the new enhanced modelling for typical Chinese NPP sites. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Courtesy stigma is the stigmatization a person perceives or experiences due to their association with a stigmatized individual or group. Most HIV-related stigma scales have been developed for people living with HIV/AIDS (PLWHAs), but not for their HIV-uninfected family members. To date, few measurement scales have been designed to measure the degree of stigma among both PLWHAs and their HIV-uninfected family members at the family level. We developed a set of courtesy stigma scales and estimated their reliability and validity from 256 PLWHAs and 256 of their HIV-uninfected family members. Exploratory and confirmatory factor analyses were performed in two independent samples: a development sample (N = 216) and a validation sample (N = 296), respectively. Two factors ("public stigma" and "self-perceived stigma") had high internal consistency reliability (Cronbach's alpha coefficient between 0.83-0.90) and good construct validity (standardized factor loading range: 0.37-0.95) in both samples. These findings document that the newly developed brief instrument is a psychometrically sound measure of HIV-related stigma among both PLWHAs and their HIV-uninfected family members.

    To describe the simultaneous occurence of an autosomal dominant inherited MSX1 mutation and an X-linked recessive inherited EDA mutation in one Chinese family with nonsyndromic oligodontia. Clinical data of characteristics of tooth agenesis were collected. MSX1 and EDA gene mutations were detected in a Chinese family of non-syndromic oligodontia. Mild hypodontia in the parents and severe oligodontia in the son was recorded. A novel missense heterozygous mutation c.517C>A (p.Arg173Ser) was detected in the MSX1 gene in the boy and the father. A homozygous missense mutation c.1001G>A (p.Arg334His) was detected in the EDA gene in the boy and the same mutant occurred heterozygously in the mother. Simultaneous occurence of two different gene mutations with different inheritence patterns, which both caused oligodontia, which occurred in one subject and in one family, was reported.

    Full Text Available Meckel-Gruber syndrome type 3 is an autosomal recessive genetic defect caused by mutations in TMEM67 gene. In our previous study, we have identified a homozygous TMEM67 mutation in a Chinese family exhibiting clinical characteristics of MKS3, which provided a ground for further PGD procedure. Here we report the development and the first clinical application of the PGD for this MKS3 family. Molecular analysis protocol for clinical PGD procedure was established using 50 single cells in pre-clinical set-up. After whole genomic amplification by multiple displacement amplification with the DNA from single cells, three techniques were applied simultaneously to increase the accuracy and reliability of genetic diagnosis in single blastomere, including real-time PCR with Taq Man-MGB probe, haplotype analysis with polymorphic STR markers and Sanger sequencing. In the clinical PGD cycle, nine embryos at cleavage-stage were biopsied and subjected to genetic diagnosis. Two embryos diagnosed as free of TMEM67 mutation were transferred and one achieving normal pregnancy. Non-invasive prenatal assessment of trisomy 13, 18 and 21 by multiplex DNA sequencing at 18 weeks' gestation excluded the aneuploidy of the analyzed chromosomes. A healthy boy was delivered by cesarean section at 39 weeks' gestation. DNA sequencing from his cord blood confirmed the result of genetic analysis in the PGD cycle. The protocol developed in this study was proved to be rapid and safe for the detection of monogenic mutations in clinical PGD cycle.

    Glanzmann's thrombasthenia is a bleeding disorder caused by qualitative and/or quantitative defects of platelet membrane glycoprotein (GP) Ii b /III a complex. The disease is inherited in an autosomal recessive manner. The use of cDNA probes to study restriction fragment length polymorphisms (RFLPs) in GPIII a gene is reported. A Taq I polymorphism was identified and this RFLP consisted of variant bands of 6.5 kb/4.0 and 2.5 kb with a frequency of 0.46/0.54 in Chinese population. The Taq I polymorphism was further localized by polymerase chain reaction (PCR) method to exon VIII of the GPIII a gene. In two Glanzmann's thrombasthenia families, the Taq I RFLP studied with both Southern blotting and PCR methods identified defective GPIII a gene inherited by patients, and determined the genotype of asymptomatic subjects. Analysis of this Taq I polymorphism by PCR method should be potentially useful in future for the carrier detection and prenatal diagnosis in Glanzmann's thrombasthenia families

    Longitudinal and lateral characteristics of the families detected by emulsion chambers in the hybrid experiment with AS-array at Mt. Chacaltaya are studied in detail. Although many groups discuss about an increase of the heavy component in primary cosmic-rays beyond the knee region, it is shown that the observed characteristics of the families accompanied by large shower size, Ne>10 6 , can not be explained by an increase of heavy primaries alone. It is necessary to assume some changes of nuclear interaction in order to explain the observed characteristics of the air-showers accompanied by families

    Hereditary neuropathy with liability to pressure palsy (HNPP), mainly associated with the peripheral myelin protein 22 (PMP22) gene, is generally an autosomal-dominant inherited peripheral neuropathy. The present large family including four generations provides an exciting opportunity to gain important insights into HNPP in China. A large 43-member family with ten members suspected to be affected by HNPP was studied. Neurologic examinations, electrophysiological and neuropathological studies and molecular genetic testing were used for these kindred. Clinically, the proband had limb hyposthenia and atrophy, and his mother showed declined tendon reflexes in the right lower limb. Electrophysiologically, sensory and motor nerve conduction velocities were generalized reduced. Sural nerve biopsy for the proband showed focal thickesning of the myelin sheaths. Furthermore, real-time quantitative PCR demonstrated that the PMP22 gene has a higher Ct value than reference gene in all suspected patients. These results indicated that the family is indeed a rare and large pedigree of HNPP caused by the deletion of PMP22 gene. Given that the suspected patient in the fourth generation is absent, this family is still worthy of further follow-up study. Copyright © 2012 S. Karger AG, Basel.

    We investigated the mechanism regulating cytoplasmic male sterility (CMS) in Brassica rapa ssp. pekinensis using floral bud transcriptome analyses of Ogura-CMS Chinese cabbage and its maintainer line in B. rapa 300-K oligomeric probe (Br300K) microarrays. Ogura-CMS Chinese cabbage produced few and infertile pollen grains on indehiscent anthers. Compared to the maintainer line, CMS plants had shorter filaments and plant growth, and delayed flowering and pollen development. In microarray analysis, 4646 genes showed different expression, depending on floral bud size, between Ogura-CMS and its maintainer line. We found 108 and 62 genes specifically expressed in Ogura-CMS and its maintainer line, respectively. Ogura-CMS line-specific genes included stress-related, redox-related, and B. rapa novel genes. In the maintainer line, genes related to pollen coat and germination were specifically expressed in floral buds longer than 3mm, suggesting insufficient expression of these genes in Ogura-CMS is directly related to dysfunctional pollen. In addition, many nuclear genes associated with auxin response, ATP synthesis, pollen development and stress response had delayed expression in Ogura-CMS plants compared to the maintainer line, which is consistent with the delay in growth and development of Ogura-CMS plants. Delayed expression may reduce pollen grain production and/or cause sterility, implying that mitochondrial, retrograde signaling delays nuclear gene expression. Copyright © 2012 Elsevier Ireland Ltd.

    Wen-Feng Wu

    Full Text Available Familial hypercholesterolemia is an autosomal dominant inherited disease characterized by elevated plasma low-density lipoprotein cholesterol (LDL-C. It is mainly caused by mutations of the low-density lipoprotein receptor (LDLR gene. Currently, the methods of whole genome sequencing or whole exome sequencing for screening mutations in familial hypercholesterolemia are not applicable in China due to high cost. We performed targeted exome sequencing of 167 genes implicated in the homozygous phenotype of a proband pedigree to identify candidate mutations, validated them in the family of the proband, studied the functions of the mutant protein, and followed up serum lipid levels after treatment. We discovered that exon 9 c.1268 T>C and exon 8 c.1129 T>G compound heterozygous mutations in the LDLR gene in the proband derived from the mother and father, respectively, in which the mutation of c.1129 T>G has not been reported previously. The mutant LDL-R protein had 57% and 52% binding and internalization functions, respectively, compared with that of the wild type. After 6 months of therapy, the LDL-C level of the proband decreased by more than 50% and the LDL-C of the other family members with heterozygous mutation also reduced to normal. Targeted exome sequencing is an effective method for screening mutation genes in familial hypercholesterolemia. The exon 8 and 9 mutations of the LDLR gene were pedigree mutations. The functions of the mutant LDL-R protein were decreased significantly compared with that of the wild type. Simvastatin plus ezetimibe was proven safe and effective in this preschool-age child.

    Full Text Available The aim of the paper is a comparison of psychological readiness of the child to go to school in nuclear and single parent families. To obtain the objectives of the paper the following methods were used: 1 methods “Two schools” by L.A Venger to identify the level of formation of internal position of the student; 2 the method “Motivational research studies in older preschoolers” by M.R. Ginsburg; 3 method “Pattern” by L.I. Tsehanskaya to determine the degree of development of skills training activities; 4 method “Graphic dictation” by D. El’konin to study the ability to follow adult instructions. The investigated group consisted of 40 students from first grade secondary school - 20 students from nuclear families (12 girls and 8 boys and 20 students from single parent families (9 girls and 11 boys. As a result of qualitative, comparative and correlation analysis it was shown that readiness of children to go to school susbstantially depends on completness of their families. The children from families have a higher level of skill training and internal position than children from single parent families. This occurs because both parents pay more attention to the children in the forming of a willingness to learn in school. The studies have shown that in the group of children from nuclear families dominate the highest level of development of skills training activities, increased formation of internal positions and childrens social motivation. These indicators are the hallmarks of readiness to learn at school. Also, some recommendations to teachers are provided as for increase of motivation to learn in children from single parent families.

    Chronic stress has adverse effects on health. Adults and children from low-income families are subject to multiple sources of stress. Existing literature about economic hardship mostly focuses on either adults or children but not both. Moreover, there is limited knowledge on the relationship between parental generalised stress and child health problems. This study aims to explore the bidirectional relationship between parental stress and child health in Chinese low-income families and to identify other modifiable factors influencing this relationship. This prospective cohort study will sample 254 low-income parent-child pairs and follow them up for 24 months with assessments at three time points (baseline, 12 and 24 months) on parental stress, health-related quality of life (HRQOL) and child health and behaviour using both subjective measures and objective physiological parameters. This study will collect data using standardised measures on HRQOL and behaviours of children as well as on HRQOL, mental health and stress levels of parents along with physiological tests of allostatic load and telomere length. The mediating or moderating effect of family harmony, parenting style and neighbourhood conditions will also be assessed. Data will be analysed using latent growth modelling and cross-lagged path analysis modelling to examine the bidirectional effect of parental stress and child health over time. Mediation and moderation analysis will also be conducted to examine the mechanism by which the variables relate. This study was approved by the institutional review board of the University of Hong Kong-the Hospital Authority Hong Kong West Cluster, reference no: UW 16-415. The study findings will be disseminated through peer-reviewed publications and international conferences.

    The dual function cytokines IL-1α, IL-33 and IL-37 are members of the IL-1 cytokine family. Besides of being able to bind to their cognate receptors on target cells, they can act intracellularly in the producing cell. All three are able to translocate to the nucleus and have been discussed to affect gene expression. In order to compare and quantitate nuclear translocation of these IL-1 family members we established a robust technique which enables to measure nuclear localization on a single cell level by flow cytometry. Vectors encoding fusion proteins of different IL-1 family members with enhanced green fluorescent protein were cloned and cell lines transiently transfected with these. Fluorescent fusion proteins in intact cells or in isolated nuclei were detected subsequently by fluorescence microscopy and flow cytometry, respectively. Depending on the cellular system, cells and nuclei were distinguishable by flow cytometry in forward scatter/sideward scatter. Fluorescent fusion proteins were detectable in isolated nuclei up to three days following preparation. Signal intensity of fusion proteins of IL-33 and IL-37 in isolated nuclei but not of IL-1α, was markedly increased by fixation with paraformaldehyde, directly following cell lysis, indicating that IL-1α binds stronger to nuclear structures than IL-33 and IL-37. Nuclear translocation of fluorescent IL-37 fusion proteins in a stably transfected RAW264.7 mouse macrophage cell line required stimulation with lipopolysaccharide. Applying this method we demonstrated that a prolonged lag phase of more than 15h before LPS-stimulated nuclear translocation was detected. In summary, we present a robust method to analyze and quantitate nuclear localization of IL-1 cytokine family members. Copyright © 2012 Elsevier B.V. All rights reserved.

    Full Text Available Abstract Background Cleidocranial dysplasia (CCD is a dominantly inherited disease characterized by hypoplastic or absent clavicles, large fontanels, dental dysplasia, and delayed skeletal development. The purpose of this study is to investigate the genetic basis of Chinese family with CCD. Methods Here, a large Chinese family with CCD and hyperplastic nails was recruited. The clinical features displayed a significant intrafamilial variation. We sequenced the coding region of the RUNX2 gene for the mutation and phenotype analysis. Results The family carries a c.T407C (p.L136P mutation in the DNA- and CBFβ-binding Runt domain of RUNX2. Based on the crystal structure, we predict this novel missense mutation is likely to disrupt DNA binding by RUNX2, and at least locally affect the Runt domain structure. Conclusion A novel missense mutation was identified in a large Chinese family with CCD with hyperplastic nails. This report further extends the mutation spectrum and clinical features of CCD. The identification of this mutation will facilitate prenatal diagnosis and preimplantation genetic diagnosis.

    To perform genotyping analysis and subsequent prenatal genetic diagnosis for two families affected with oculocutaneous albinism (OCA). Direct sequencing of TYR and P genes was performed in two albino probands. Family members were screened for corresponding mutant alleles. Prenatal genetic diagnoses were performed at early pregnancy by chorionic villus sampling (CVS) at mid-pregnancy through amniocentesis. No mutations were detected in the TYR gene in either probands, whereas 4 heterozygous mutations of the P gene were found, namely c.406C>T, c.535A>G, c.808-2A>G and c.2180T>C, among which c.535A>G and c.808-2A>G were novel. In the first round prenatal genetic testing, both fetuses were found to have the same genotypes as the probands. Both families had decided to terminate the pregnancy after genetic counseling. In the second round testing, neither of the fetuses was found to be affected by genotyping. The pregnancies continued and two healthy fetuses were born. OCA can be classified by genotyping, with which reliable prenatal diagnosis and feasible genetic counseling may be provided.

    Stroke is a leading cause of adult disability and community re-integration is a priority for stroke rehabilitation. In North America, we have a growing population of individuals whose first language is not English. Little is known about the experiences of visible minorities living in North America as they re-integrate into the community post stroke or how these experiences change over time. Specifically, this research aimed to explore the experiences and needs of Chinese stroke survivors and family caregivers as they return to community living using the Timing it Right Framework as a conceptual guide. We recruited Cantonese-speaking stroke survivors and family caregivers from outpatient rehabilitation programmes. Using qualitative interviews conducted in Cantonese or English, we examined their experiences and needs as they return to community living and explored the influence of culture and time on their experiences. The interviews were transcribed and translated, and then analysed using framework analysis. Using framework analysis, we coded the data corresponding to the phases of the Timing it Right framework to determine the influence of time on the themes. We interviewed five Cantonese-speaking stroke survivors and 13 caregivers in 2009. We identified two main themes: (i) Participants' education and support needs change over time and (ii) Chinese resources are needed across care environments. These resources include access to care in their preferred language, traditional Chinese medicine, and Chinese food during their recovery and rehabilitation. To optimise Chinese stroke survivors' and caregivers' community re-integration, healthcare professionals should provide timely and accessible education and be aware of the role of Chinese diet and traditional medicine in stroke survivors' rehabilitation. © 2014 John Wiley & Sons Ltd.

    A pediatric chronic health condition not only influences a child's life, but also has impacts on parent health-related quality of life (HRQOL) and family functioning. To provide care and social support to these families, a psychometrically well-developed instrument for measuring these impacts is of great importance. The present study is aimed to evaluate the psychometric properties of the Chinese version of the PedsQL™ Family Impact Module. The cross-cultural adaptation of the PedsQL™ Family Impact Module was performed following the PedsQL™ Measurement Model Translation Methodology. The Chinese version of the PedsQL™ Family Impact Module was administered to 136 parents of children with asthma and 264 parents of children with heart disease from four Triple A hospitals. The psychometric properties such as feasibility, internal consistency reliability, item-subscale correlations and construct validity were evaluated. The percentage of missing item responses was less than 0.1% for both asthma and heart disease sample groups. The Chinese version of the PedsQL™ Family Impact Module showed ceiling effects but had acceptable reliability (Cronbach's Alpha Coefficients were higher than 0.7 in all the subscales except "Daily Activities" in the asthma sample group). There were higher correlation coefficients between items and their hypothesized subscales than those with other subscales. The asthma sample group reported higher parent HRQOL and family functioning than the heart disease sample group. In the heart disease sample group, parents of outpatients reported higher parent HRQOL and family functioning than parents of inpatients. Confirmatory factor analysis showed that the instrument had marginally acceptable construct validity with some Goodness-of-Fit indices not reaching the standard indicating acceptable model fit. The Chinese version of the PedsQL™ Family Impact Module has adequate psychometric properties and could be used to assess the impacts of

    Brachydactyly type A1 (BDA1) is caused by mutations in the Indian hedgehog gene, IHH, on chromosome 2q35-36. In this study, a large five-generation Chinese family with BDA1 was identified and characterized. All affected family members demonstrated significant homogeneous phenotype and some unique clinical features different from those associated with the reported BDA1 mutations in IHH. Linkage analysis showed that the BDA1 gene in the family was linked to marker D2S126 close to IHH with a LOD score of 4.74 at a recombination fraction of 0. DNA sequence analysis revealed a heterozygous C to T transition at nucleotide 461 of IHH, resulting in a novel T154I substitution. The T154I mutation co-segregated with all affected individuals in the family, and was not present in normal family members or 200 normal controls. These results expand the spectrum of clinical phenotype associated with IHH mutations.

    Family-centred service (FCS) has become essential to parents of children with cerebral palsy (CP) and professionals in Chinese paediatric rehabilitation services. FCS practice meets the unique needs of the child and family, through facilitation of optimal service provision delivered by professionals, and ensures service systems to be flexible, appropriate and actively responsive to the family needs. Parents used the Measure of Processes of Care 20 (MPOC-20) questionnaire to evaluate and verify the efficacy of use in China. The aims of the present study were twofold: to assess the validity and reliability of the Chinese MPOC-20, and investigate the range of parents' satisfaction with service provision in an FCS practice using the MPOC-20. The Chinese MPOC-20 was selected to assess parent satisfaction with service provision of professionals in FCS practice. Participants were parents of children under 8 years of age with CP, who had received rehabilitation services between May 2012 and May 2013, and were receiving rehabilitation services in May 2013 at a hospital outpatient department and a rehabilitation centre. The reliability and validity of the Chinese MPOC-20 were confirmed. Parents evaluated FCS practice with the MPOC-20 survey. Respectful and supportive care was rated with the highest score and providing general information the lowest. Parents according to the data were dissatisfied with the lack of information. Parents fairly evaluated service provision of professionals in FCS practice with the Chinese MPOC-20. Professionals received feedback reports of parents, summaries of the inadequacy of service delivery, and developed and implemented ameliorated measures in the FCS policy to strive to provide exemplary service. © 2014 John Wiley & Sons Ltd.

    There is growing evidence that genetic factors also contribute to drug addiction. The human cytochrome P450 has shown special interest because of pharmacokinetic variation in different individuals and populations, which is largely determined by the relevant genes. The present study aimed to investigate the polymorphism of the CYP/addicts relationship. We genotyped 13 tag single-nucleotide polymorphisms (tSNPs) from three genes, including 692 cases and 700 controls. Sequenom MassARRAY RS1000 (Sequenom, Inc., San Diego, CA, USA) was used for SNP genotyping. Statistical analysis of the association between tSNPs and drug addiction was performed using the chi-squared test and SNP Stats software (http://bioinfo.iconcologia.net). The T/T genotype of rs2242480 in CYP3A4 was associated with decreased risk in the recessive model (p = 0.0002). Allele frequency at rs3743484 in CYP1A2 showed significant differences between addicts and controls (p = 0.046; odds ratio = 0.80; 95% confidence interval = 0.65-1.00). In genetic model analyses, the minor C allele of rs3743484 in CYP1A2 was associated with a reduced risk of drug addiction based on analysis using codominant and additive models (p = 0.027 dominant model; p =0.038 additive model). Our findings show that at allelic and genotypic level polymorphisms in CYP3A4 and CYP1A2 are significantly associated with a reduced risk of drug addiction in X'ian Han Chinese individuals. However, this result needs to be confirmed in additional studies. Copyright © 2016 John Wiley & Sons, Ltd. Copyright © 2016 John Wiley & Sons, Ltd.

    Autism spectrum disorder is a group of neurodevelopmental disorders with the higher prevalence in males. Our previous studies have indicated lower progesterone levels in the children with autism spectrum disorder, suggesting involvement of the cytochrome P-450scc gene (CYP11A1) and cytochrome P-45011beta gene (CYP11B1) as candidate genes in autism spectrum disorder. The aim of this study was to investigate the family-based genetic association between single-nucleotide polymorphisms, rs2279357 in the CYP11A1 gene and rs4534 and rs4541 in the CYP11B1 gene and autism spectrum disorder in Chinese children, which were selected according to the location in the coding region and 5' and 3' regions and minor allele frequencies of greater than 0.05 in the Chinese populations. The transmission disequilibrium test and case-control association analyses were performed in 100 Chinese Han autism spectrum disorder family trios. The genotype and allele frequency of the 3 single-nucleotide polymorphisms had no statistical difference between the children with autism spectrum disorder and their parents (P> .05). Transmission disequilibrium test analysis showed transmission disequilibrium of CYP11A1 gene rs2279357 single-nucleotide polymorphisms (χ(2)= 5.038,Pautism spectrum disorder exists within or near the CYP11A1 gene in the Han Chinese population. © The Author(s) 2015.

    After the Fukushima severe accident, nuclear power development has been in stagnation in all over the world. The Chinese nuclear industry has a slowdown on new NPP construction. As a result, high level technique on safety and effective communication are required. For nuclear power engineering company with EPC mode, high quality on training and technical communication is the principal investment in order to achieve better service on engineering design, environmental impact assessment, environmental engineering design, and equipment supervision and so on. EPC mode requires wide range knowledge on almost every field related to nuclear on nuclear power engineering. In this paper, the author investigated the case of the only nuclear power engineering EPC company (CNPE) in China and present an overview on its training and technical communication both domestic and abroad. Basically, there are 4 main branches of training. The internal training focuses on specifically task (both management and technique), such as HSE training, QC training and quality and safety training. Long term education in the university is organized by cooperated mechanism. Code and platform training is partly carried out by international organization or company, and the experienced engineers coach makes up the other part. The communication is a large part since the EPC mode needs the information and requirements from the NPP entity, authority, and the other institutes, international organizations (like IAEA, NINE, IRSN, OECD, NRC and CEA etc.) and sometimes the public. The overview of the training and communication of the EPC company prevails the outline of its advantage on domestic communication and disadvantage on international technical communication. The paper can be a tool on the soft strength construction of company under EPC mode to broaden its business like consultation and training. Some advice is given by the author on the consultation and global communication in the future. (author)

    Waardenburg syndrome is clinically and genetically heterogeneous. The SOX10 mutation related with Waardenburg syndrome type II is rare in Chinese. This study aimed to uncover the genetic causes of Waardenburg syndrome type II in a three-generation family to improve genetic counseling. Complete clinical and molecular evaluations were conducted in a three-generation Han Chinese family with Waardenburg syndrome type II. Targeted genetic counseling was provided to this family. We identified a rare heterozygous dominant mutation c.621C>A (p.Y207X) in SOX10 gene in this family. The premature termination codon occurs in exon 4, 27 residues downstream of the carboxyl end of the high mobility group box. Bioinformatics prediction suggested this variant to be disease-causing, probably due to nonsense-mediated mRNA decay. Useful genetic counseling was given to the family for prenatal guidance. Identification of a rare dominant heterozygous SOX10 mutation c.621C>A in this family provided an efficient way to understand the causes of Waardenburg syndrome type II and improved genetic counseling.

    2017-06-01

    The nuclear receptor-binding SET Domain (NSD) family of histone H3 lysine 36 methyltransferases is comprised of NSD1, NSD2 (MMSET/WHSC1), and NSD3 (WHSC1L1). These enzymes recognize and catalyze methylation of histone lysine marks to regulate chromatin integrity and gene expression. The growing number of reports demonstrating that alterations or translocations of these genes fundamentally affect cell growth and differentiation leading to developmental defects illustrates the importance of this family. In addition, overexpression, gain of function somatic mutations, and translocations of NSDs are associated with human cancer and can trigger cellular transformation in model systems. Here we review the functions of NSD family members and the accumulating evidence that these proteins play key roles in tumorigenesis. Because epigenetic therapy is an important emerging anticancer strategy, understanding the function of NSD family members may lead to the development of novel therapies.

    Autosomal dominant optic atrophy (ADOA) is the most frequent form of hereditary optic neuropathy and occurs due to the degeneration of the retinal ganglion cells. To identify the genetic defect in a family with putative ADOA, we performed capture next generation sequencing (CNGS) to screen known retinal disease genes. However, six exons failed to be sequenced by CNGS in optic atrophy 1 gene (OPA1). Sequencing of those exons identified a 4 bp deletion mutation (c.2983-1_2985del) in OPA1. Furthermore, we sequenced the transcripts of OPA1 from the patient skin fibroblasts and found there is six-nucleotide deletion (c.2984-c.2989, AGAAAG). Quantitative-PCR and Western blotting showed that OPA1 mRNA and its protein expression have no obvious difference between patient skin fibroblast and control. The analysis of protein structure by molecular modeling suggests that the mutation may change the structure of OPA1 by formation of an alpha helix protruding into an existing pocket. Taken together, we identified an OPA1 mutation in a family with ADOA by filling the missing CNGS data. We also showed that this mutation affects the structural intactness of OPA1. It provides molecular insights for clinical genetic diagnosis and treatment of optic atrophy.

    The amyloid precursor protein (APP) as well as its homologues, APP-like protein 1 and 2 (APLP1 and APLP2), are cleaved by α-, β-, and γ-secretases, resulting in the release of their intracellular domains (ICDs). We have shown that the APP intracellular domain (AICD) is transported to the nucleus by Fe65 where they jointly bind the histone acetyltransferase Tip60 and localize to spherical nuclear complexes (AFT complexes), which are thought to be sites of transcription. We have now analyzed the subcellular localization and turnover of the APP family members. Similarly to AICD, the ICD of APLP2 localizes to spherical nuclear complexes together with Fe65 and Tip60. In contrast, the ICD of APLP1, despite binding to Fe65, does not translocate to the nucleus. In addition, APLP1 predominantly localizes to the plasma membrane, whereas APP and APLP2 are detected in vesicular structures. APLP1 also demonstrates a much slower turnover of the full-length protein compared to APP and APLP2. We further show that the ICDs of all APP family members are degraded by the proteasome and that the N-terminal amino acids of ICDs determine ICD degradation rate. Together, our results suggest that different nuclear signaling capabilities of APP family members are due to different rates of full-length protein processing and ICD proteasomal degradation. Our results provide evidence in support of a common nuclear signaling function for APP and APLP2 that is absent in APLP1, but suggest that APLP1 has a regulatory role in the nuclear translocation of APP family ICDs due to the sequestration of Fe65.

    Waardenburg syndrome type 4 (WS4) or Waardenburg-Shah syndrome is a rare genetic disorder with a prevalence of <1/1,000,000 and characterized by the association of congenital sensorineural hearing loss, pigmentary abnormalities, and intestinal aganglionosis. There are three types of WS4 (WS4A-C) caused by mutations in endothelin receptor type B, endothelin 3, and SRY-box 10 (SOX10), respectively. This study investigated a genetic mutation in a Chinese family with one WS4 patient in order to improve genetic counselling. Genomic DNA was extracted, and mutation analysis of the three WS4 related genes was performed using Sanger sequencing. We detected a de novo heterozygous deletion mutation [c.1333delT (p.Ser445Glnfs*57)] in SOX10 in the patient; however, this mutation was absent in the unaffected parents and 40 ethnicity matched healthy controls. Subsequent phylogenetic analysis and three-dimensional modelling of the SOX10 protein confirmed that the c.1333delT heterozygous mutation was pathogenic, indicating that this mutation might constitute a candidate disease-causing mutation.

    Calculations of the resonance integrals of particular isotopes in a mixture of isotopes show that the overlapping of the resonances of one isotope by resonances of other isotopes affects the final values of effective cross sections. The same effect might adversely influence those nondestructive techniques which assay fissile materials on the basis of resonance effects. Of relevance for these applications is the knowledge of the probability of overlapping resonances of a family of nuclear levels (class 1) with resonances of an independent family (class 2). For the sequence of class 1 resonances we calculate the probability distribution, p(delta), to find a class 2, first-neighbor resonance at distance (in energy) delta from a class 1 resonance; integration of p(delta) over the average finite width of the resonances would give the aforementioned probability of overlapping. Because a class 1 resonance can have a class 1 or a class 2 resonance as a first neighbor, the resultant p(delta) is not given by the distribution of spacings of the composite family

    Myocardin (Mycd), which is essential for the differentiation of the smooth muscle cell lineage, is constitutively located in the nucleus, although its family members, myocardin-related transcription factors A and B (MRTF-A/B), mostly reside in the cytoplasm and translocate to the nucleus in response to Rho signaling. The mechanism for their nuclear import is unclear. Here we investigated the mechanism for the nuclear import of Mycd family members and demonstrated any correlation between such mechanism and the phenotype of vascular smooth muscle cells (VSMCs). In cultured VSMCs, the knockdown of importin β1 inhibited the nuclear import of Mycd and MRTF-A/B. Their NH(2)-terminal basic domain was identified as a binding site for importin α/β1 by in vitro analyses. However, Mycd had a higher affinity for importin α/β1 than did MRTF-A/B, even in the absence of G-actin, and Mycd affinity for importin α1/β1 was stronger than for any other importin α/β1 heterodimers. The binding of Mycd to importin α/β1 was insensitive to G-actin, whereas that of MRTF-A/B was differently inhibited by G-actin. In dedifferentiated VSMCs, the levels of importins α1 and β1 were reduced concomitant with down-regulation of Mycd, serum response factor, and smooth muscle cell markers. By contrast, in differentiated VSMCs, their expressions were up-regulated. Thus, the nuclear import of Mycd family members in VSMCs depends on importin α/β1, and their relative affinities for importin α/β1 heterodimers determine Mycd nuclear import. The expression of Mycd nuclear import machineries is related to the expression levels of VSMC phenotype-dependent smooth muscle cell markers.

    Full Text Available AIM:To investigate the genetic findings and phenotypic characteristics of a Chinese family with Norrie disease (ND.METHODS:Molecular genetic analysis and clinical examinations were performed on a Chinese family with ND. Mutations in the Norrie disease pseudoglioma (NDP gene were detected by direct sequencing. Haplotypes were constructed and compared with the phenotypes in the family. Evolutionary comparisons and mutant open reading frame (ORF prediction were also undertaken.RESULTS:Two family members with ocular manifestations were diagnosed with ND. No signs of sensorineural hearing loss were observed in either patient, while one of them showed signs of mild mental retardation. A novel heterozygous mutation in the NDP gene, c.-1_2delAAT, was detected in both patients. The mutation and the mutation bearing haplotype co-segregated with the ND phenotype in males and was transmitted from their mothers and/or grandmothers (II:2. The male without ND did not harbor the mutation. The mutation occurred at the highly conserved nucleotides. ORF finder predicted that the mutation would lead to the production of a truncated protein that lacks the first 11 N-terminal amino acids.CONCLUSION:A novel mutation, c.-1_2delAAT in the NDP gene, was identified in a Chinese family with ND. This mutation caused ND without obvious sensorineural hearing loss. Mental disorder was found in one but not the other patients. The clinical heterogeneity in the family indicated that other genetic variants and epigenetic factors may also play a role in the disease presentation.

  2. Handling missing data in transmission disequilibrium test in nuclear families with one affected offspring.

    Full Text Available The Transmission Disequilibrium Test (TDT compares frequencies of transmission of two alleles from heterozygote parents to an affected offspring. This test requires all genotypes to be known from all members of the nuclear families. However, obtaining all genotypes in a study might not be possible for some families, in which case, a data set results in missing genotypes. There are many techniques of handling missing genotypes in parents but only a few in offspring. The robust TDT (rTDT is one of the methods that handles missing genotypes for all members of nuclear families [with one affected offspring]. Even though all family members can be imputed, the rTDT is a conservative test with low power. We propose a new method, Mendelian Inheritance TDT (MITDT-ONE, that controls type I error and has high power. The MITDT-ONE uses Mendelian Inheritance properties, and takes population frequencies of the disease allele and marker allele into account in the rTDT method. One of the advantages of using the MITDT-ONE is that the MITDT-ONE can identify additional significant genes that are not found by the rTDT. We demonstrate the performances of both tests along with Sib-TDT (S-TDT in Monte Carlo simulation studies. Moreover, we apply our method to the type 1 diabetes data from the Warren families in the United Kingdom to identify significant genes that are related to type 1 diabetes.

    Caregiving can be stressful, potentially creating physical and psychological strain. Substantial evidence has shown that family caregivers suffer from significant health problems arising from the demands of caregiving. Although there are programs supporting caregivers, there is little evidence regarding their effectiveness. Acupressure is an ancient Chinese healing method designed to restore the flow of Qi (vital energy) by applying external pressure to acupoints. A randomized, wait-list controlled trial was developed to evaluate the effectiveness of a self-administered acupressure intervention on caregiver stress (primary objective) and stress-related symptoms of fatigue, insomnia, depression, and health-related quality of life (secondary objectives) in Chinese caregivers of older family members. Two hundred Chinese participants, aged ≥ 21 years, who are the primary caregivers of an older family member and screen positive for caregiver stress and symptoms of fatigue/insomnia/depression will be recruited from a community setting in Hong Kong. Subjects will be randomized to receive either an immediate treatment condition (self-administered acupressure intervention) or a wait-list control condition. The self-administered acupressure intervention will include (i) an individual learning and practice session twice a week for 2 weeks, (ii) a home follow-up visit once a week for 2 weeks, and (iii) 15-min self-practice twice a day for 6 weeks. The wait-list control group will receive the same acupressure training after the intervention group has completed the intervention. We hypothesize that Chinese family caregivers in the intervention group will have lower levels of caregiver stress, fatigue, insomnia, depression, and higher health-related quality of life after completion of the intervention than participants in the wait-list control group. This study will provide evidence for the effectiveness of self-administered acupressure in reducing stress and improving

    . The distinctive radiological signs and the X-linked mode of inheritance make it easy to diagnose. Here a four-generation Chinese SEDT family has been analyzed and the disease-causing mutation has been found. After polymerase chain reaction (PCR)-single strand conformation polymorphism (SSCP) analysis and DNA...... sequencing, a previously unreported deletion of T in exon 5 of SEDL gene (i.e. 293delT) was observed and seven individuals in the family carried the mutation. It results in frameshift and a putative truncated protein with the 97 N-terminal amino acids, and 9 changed amino acids. Therefore, loss of function...

  5. Cloning and Functional Analysis of Histones H3 and H4 in Nuclear Shaping during Spermatogenesis of the Chinese Mitten Crab, Eriocheir sinensis.

    Full Text Available During spermatogenesis in most animals, the basic proteins associated with DNA are continuously changing and somatic-typed histones are partly replaced by sperm-specific histones, which are then successively replaced by transition proteins and protamines. With the replacement of sperm nuclear basic proteins, nuclei progressively undergo chromatin condensation. The Chinese Mitten Crab (Eriocheir sinensis is also known as the hairy crab or river crab (phylum Arthropoda, subphylum Crustacea, order Decapoda, and family Grapsidae. The spermatozoa of this species are aflagellate, and each has a spherical acrosome surrounded by a cup-shaped nucleus, peculiar to brachyurans. An interesting characteristic of the E. sinensis sperm nucleus is its lack of electron-dense chromatin. However, its formation is not clear. In this study, sequences encoding histones H3 and H4 were cloned by polymerase chain reaction amplification. Western blotting indicated that H3 and H4 existed in the sperm nuclei. Immunofluorescence and ultrastructural immunocytochemistry demonstrated that histones H3 and H4 were both present in the nuclei of spermatogonia, spermatocytes, spermatids and mature spermatozoa. The nuclear labeling density of histone H4 decreased in sperm nuclei, while histone H3 labeling was not changed significantly. Quantitative real-time PCR showed that the mRNA expression levels of histones H3 and H4 were higher at mitotic and meiotic stages than in later spermiogenesis. Our study demonstrates that the mature sperm nuclei of E. sinensis contain histones H3 and H4. This is the first report that the mature sperm nucleus of E. sinensis contains histones H3 and H4. This finding extends the study of sperm histones of E. sinensis and provides some basic data for exploring how decapod crustaceans form uncondensed sperm chromatin.

    This work intends to quantify the risk of internal contaminations in the nuclear medicine staff of one hospital in Henan province, China. For this purpose, the criteria proposed by the International Atomic Energy Agency (IAEA) to determine whether it is necessary to conduct internal individual monitoring was applied to all of the 18 nuclear medicine staff members who handled radionuclides. The activity of different radionuclides used during a whole calendar year and the protection measures adopted were collected for each staff member, and the decision as to whether nuclear medicine staff in the hospital should be subjected to internal monitoring was made on the basis of the criteria proposed by IAEA. It is concluded that for all 18 members of the nuclear medicine staff in the hospital, internal monitoring is required. Internal exposure received by nuclear medicine staff should not be ignored, and it is necessary to implement internal monitoring for nuclear medicine staff routinely.

    Full Text Available BACKGROUND: The contribution of low-penetrant susceptibility variants to cancer is not clear. With the aim of searching for genetic factors that contribute to cancer at one or more sites in the body, we have analyzed familial aggregation of cancer in extended families based on all cancer cases diagnosed in Iceland over almost half a century. METHODS AND FINDINGS: We have estimated risk ratios (RRs of cancer for first- and up to fifth-degree relatives both within and between all types of cancers diagnosed in Iceland from 1955 to 2002 by linking patient information from the Icelandic Cancer Registry to an extensive genealogical database, containing all living Icelanders and most of their ancestors since the settlement of Iceland. We evaluated the significance of the familial clustering for each relationship separately, all relationships combined (first- to fifth-degree relatives and for close (first- and second-degree and distant (third- to fifth-degree relatives. Most cancer sites demonstrate a significantly increased RR for the same cancer, beyond the nuclear family. Significantly increased familial clustering between different cancer sites is also documented in both close and distant relatives. Some of these associations have been suggested previously but others not. CONCLUSION: We conclude that genetic factors are involved in the etiology of many cancers and that these factors are in some cases shared by different cancer sites. However, a significantly increased RR conferred upon mates of patients with cancer at some sites indicates that shared environment or nonrandom mating for certain risk factors also play a role in the familial clustering of cancer. Our results indicate that cancer is a complex, often non-site-specific disease for which increased risk extends beyond the nuclear family.

    Spinocerebellar ataxias (SCAs) are a group of autosomal dominant, clinically heterogeneous neurodegenerative disorders. SCA18 is a rare autosomal dominant sensory/motor neuropathy with ataxia (OMIM#607458) associated with a single missense variant c.514 A>G in the interferon related developmental regulator 1 (IFRD1) gene previously reported in a five-generation American family of Irish origin. However, to date, there have been no other reports of the IFRD1 mutation to confirm its role in SCA. Here, we report a Han Chinese family with SCA18; the family members presented with a slowly progressing gait ataxia, pyramidal tract signs, and peripheral neuropathy. We identified a missense variant (c.514 A>G, p.I172V) in IFRD1 gene in the family using targeted next-generation sequencing and Sanger direct sequencing with specific primers. Our results suggest that the IFRD1 gene may be the causative allele for SCA18.

    This study used the data from a representative sample to investigate the association between family violence (FV) and child bullying victimization (BV) in Xi'an city, China. Data on social demographic information and the prevalence of BV and FV were collected from a randomly selected sample with 3,175 middle school students aged 15 to 17 by self-administrated questionnaires. Results show that 55.9% and 30.3% of the participants have witnessed intimate partner violence (IPV), 37.7% and 30.8% have been victims of child abuse, and 54.9% and 44.6% have been bullied in a lifetime and in the preceding year, respectively. The lifetime and preceding-year co-occurrence rate of FV and BV are 45% and 30.4%, respectively. Multiple logistic regressions confirm FV as a unique risk factor in predicting both direct and relational BV after controlling for a number of confounding factors. This study suggests that FV experiences should be included in the screening and assessment of risk for child BV.

  11. Identification of Two Disease-causing Genes TJP2 and GJB2 in a Chinese Family with Unconditional Autosomal Dominant Nonsyndromic Hereditary Hearing Impairment

    2015-01-01

    Full Text Available Background: There are more than 300 genetic loci that have been found to be related to hereditary hearing impairment (HHI, including 92 causative genes for nonsyndromic hearing loss, among which 34 genes are related to autosomal dominant nonsyndromic HHI (ADNSHHI. Traditional linkage analysis and candidate gene sequencing are not effective at detecting the ADNSHHI, especially for the unconditional families that may have more than one pathogenic cause. This study identified two disease-causing genes TJP2 and GJB2 in a Chinese family with unconditional ADNSHHI. Methods: To decipher the genetic code of a Chinese family (family 686 with ADNSHHI, different gene screening techniques have been performed, including linkage analysis, candidate genes screening, high-throughput sequencing and Sanger sequencing. These techniques were done on samples obtained from this family over a period of 10 years. Results: We identified a pathogenic missense mutation, c. 2081G>A (p.G694E, in TJP2, a gene that plays a crucial role in apoptosis and age-related hearing loss (ARHL. The mutation was co-segregated in this pedigree in all, but not in the two patients who presented with different phenotypes from the other affected family members. In one of the two patients, we confirmed that the compound heterozygosity for p.Y136FNx01 and p.G45E in the GJB2 gene may account for the phenotype shown in this patient. Conclusions: We identified the co-occurrence of two genetic causes in family 686. The possible disease-causing missense mutation of TJP2 in family 686 presents an opportunity for further investigation into ARHL. It is necessary to combine various genes screening methods, especially for some unconventional cases.

    The nuclear envelope is considered a key classification marker that distinguishes prokaryotes from eukaryotes. However, this marker does not apply to the family Planctomycetaceae, which has intracellular spaces divided by lipidic intracytoplasmic membranes (ICMs). Nuclear localization signal (NLS), a short stretch of amino acid sequence, destines to transport proteins from cytoplasm into nucleus, and is also associated with the development of nuclear envelope. We attempted to investigate the NLS motifs in Planctomycetaceae genomes to demonstrate the potential molecular transition in the development of intracellular membrane system. In this study, we identified NLS-like motifs that have the same amino acid compositions as experimentally identified NLSs in genomes of 11 representative species of family Planctomycetaceae. A total of 15 NLS types and 170 NLS-bearing proteins were detected in the 11 strains. To determine the molecular transformation, we compared NLS-bearing protein abundances in the 11 representative Planctomycetaceae genomes with them in genomes of 16 taxonomically varied microorganisms: nine bacteria, two archaea and five fungi. In the 27 strains, 29 NLS types and 1101 NLS-bearing proteins were identified, principal component analysis showed a significant transitional gradient from bacteria to Planctomycetaceae to fungi on their NLS-bearing protein abundance profiles. Then, we clustered the 993 non-redundant NLS-bearing proteins into 181 families and annotated their involved metabolic pathways. Afterwards, we aligned the ten types of NLS motifs from the 13 families containing NLS-bearing proteins among bacteria, Planctomycetaceae or fungi, considering their diversity, length and origin. A transition towards increased complexity from non-planctomycete bacteria to Planctomycetaceae to archaea and fungi was detected based on the complexity of the 10 types of NLS-like motifs in the 13 NLS-bearing proteins families. The results of this study reveal that

    On March 11, 2011, the northeastern coast of Japan was struck by 9.0-magnitude earthquake that triggered a devastating tsunami. Aside from the huge toll in people's lives and severe damages to property, the tremor sent the Fukushima Daiichi Nuclear Power Plant on a tailspin, causing hydrogen explosions in three reactors, and sending radioactive materials into the air and bodies of water. Declared the largest nuclear disaster since Chernobyl, the crisis threatened neighboring countries, including China (International Business Times, 2011). On March 28, low levels of iodine-131, cesium-137 and strontium, believed to have drifted from Japan, were detected in the air over Heilongjiang province in the northeast part of China and in seawater samples collected in the eastern coastal areas (Qianjiang Eve News, 2011). Because these chemicals can enter the food chain and adversely affect human health (Ifeng.com, 2011), people became understandably anxious and the government had to avert panic. This study asks: How did the Chinese media report the risks attendant to this event? A content analysis of 45 straight news reports published by the Chinese press from March 16, 2011 to April 25, 2011 was conducted. The analysis focused on how the media explained the risk, portrayed potential harm, reported on government actions to safeguard public health, and provided suggestions to reduce public fear. The sources of information cited in the reports were also identified. The articles examined were collected from People.com, a comprehensive online archive of news reports, using 'Fukushima' and 'nuclear radiation' as search terms. The results indicated journalistic practices that left much to be desired in terms of risk reporting. First, the articles explained little about the technical aspects of the radiation leaks and failed to give audiences a general indication of levels of risk. Second, the media over-emphasized the government's position that the

    This report documents Qinshan CANDU project construction and commissioning experience as well as management strategies and approaches that contributed to the successful completion of the project. The Qinshan phase III (CANDU) nuclear power plant was built in record times: Unit 1 achieved commercial operation on December 31, 2002 and Unit 2 on July 24, 2003, 43 days and 112 days ahead of schedule respectively. The reference plant design is the Wolsong 3 and 4 CANDU-6 units in the Republic of Korea. Improvements in design and construction methods allowed Unit 1 to be constructed in 51.5 Months from First Concrete to Criticality-a record in China for nuclear power plants. The key factors are project management and project management tools, quality assurance, construction methods (including open top construction, heavy lifts and modularization), electronic documentation with configuration control that provides up-to-date on-line information, CADDS design linked with material management, specialized material control including bar coding, and planning. The introduction of new design and construction techniques was achieved by combining conventional AECL practices with working experiences in China. The most advanced tools and techniques for achieving optimum construction quality, schedule and cost were used. Successful application of advanced project management methods and tools will benefit TQNPC in operation of the station, and the Chinese contractors in advancing their capabilities in future nuclear projects in China and enhancing their opportunities internationally. TQNPC's participation in Quality surveillance (QS) activities of nuclear steam plant (NSP) and Balance of Plant (BOP) offshore equipment benefited TQNPC in acquiring knowledge of specific equipment manufacturing processes, which can be applied to similar activities in China. China has established the capability of manufacturing CANDU fuel and becoming self-reliant in fuel supply. Excellent co-operation and

    Mutations in mitochondrial DNA (mtDNA) have been found to be associated with sensorineural hearing loss. We report here the clinical, genetic, and molecular characterization of 16 Chinese pedigrees (a total of 246 matrilineal relatives) with aminoglycoside-induced impairment. Clinical evaluation revealed the variable phenotype of hearing impairment including audiometric configuration in these subjects, although these subjects share some common features: being bilateral and sensorineural hearing impairment. Strikingly, these Chinese pedigrees exhibited extremely low penetrance of hearing loss, ranging from 4% to 18%, with an average of 8%. In particular, nineteen of 246 matrilineal relatives in these pedigrees had aminoglycoside-induced hearing loss. Mutational analysis of the mtDNA in these pedigrees showed the presence of homoplasmic 12S rRNA A1555G mutation, which has been associated with hearing impairment in many families worldwide. The extremely low penetrance of hearing loss in these Chinese families carrying the A1555G mutation strongly supports the notion that the A1555G mutation itself is not sufficient to produce the clinical phenotype. Children carrying the A1555G mutation are susceptible to the exposure of aminoglycosides, thereby inducing or worsening hearing impairment, as in the case of these Chinese families. Using those genetic and molecular approaches, we are able to diagnose whether children carry the ototoxic mtDNA mutation. Therefore, these data have been providing valuable information and technology to predict which individuals are at risk for ototoxicity, to improve the safety of aminoglycoside therapy, and eventually to decrease the incidence of deafness

    A systematic analysis is made on the 106 γ-ray families with visible energy in the range of 100--300 TeV observed in the Chacaltaya emulsion chamber experiment. A new method called 'decascading' is introduced to pick up a cluster of γ-rays and electrons in a family, so that the cluster is an air cascade from one parent γ-ray. The application of 'decascading' method to the family data gives information on original γ-rays produced at the atmospheric nuclear interactions. The results are compared with expected ones from the simulation calculation on the base of H-quantum model, and with data from the target interactions at lower energy range (ΣE sub(γ)=20 --100 TeV). The conclusion is that the characteristics of nuclear interactions at the concerned family energy range (E 0 asymptotically equals 1,000 TeV) are in accordance with those at the target interaction range (E 0 asymptotically equals 100 TeV), with increased ratio of frequencies of a heavy fire-ball (SH-quantum) to a small and usual fire-ball (H-quantum).

    Neonatal cholestasis is a potentially life-threatening condition requiring prompt diagnosis. Mutations in several different genes can cause progressive familial intrahepatic cholestasis, but known genes cannot account for all familial cases. Here we report four individuals from two unrelated families with neonatal cholestasis and mutations in NR1H4, which encodes the farnesoid X receptor (FXR), a bile acid-activated nuclear hormone receptor that regulates bile acid metabolism. Clinical features of severe, persistent NR1H4-related cholestasis include neonatal onset with rapid progression to end-stage liver disease, vitamin K-independent coagulopathy, low-to-normal serum gamma-glutamyl transferase activity, elevated serum alpha-fetoprotein and undetectable liver bile salt export pump (ABCB11) expression. Our findings demonstrate a pivotal function for FXR in bile acid homeostasis and liver protection. PMID:26888176

    During the past 30 years, economy of China has being grown strongly. Even in the year 2009, when the world was hit by the financial crisis, China still kept the 8.7% growth rate. GDP of China has reached 4222G USD. This figure makes China to become the third economic giant in the world. All of the world are focusing on the high-speed development of economy in China; meanwhile they also pay much attention on the energy consumption in China. In addition, as one of the policy to keep the stable supply of the energy and to cut off the drain of CO 2 , China now are building more and more nuclear power stations. Many developed countries are very interested in the big market. Some have already joined in the construction of nuclear power stations in China, while some may concern about the supply of the nuclear fuel, as well as nuclear safety in China. The present paper will give a close-up view on China status of the energy, especially the nuclear power industry. It is expected that the international community could have deeper and more complete understanding on the nuclear industry in China, moreover cooperate with China to improve the peace and safe utilization of nuclear energy for the sustainable development of the world.

    Laron syndrome is an autosomal recessive disorder caused by defects of growth hormone receptor (GHR) gene. It is characterized by severe postnatal growth retardation and characteristic facial features as well as high circulating levels of growth hormone (GH) and low levels of insulin-like growth factor I (IGF-I) and insulin-like growth factor binding protein-3 (IGFBP-3). This report described the clinical features and GHR gene mutations in 2 siblings with Laron syndrome in a Chinese family. Their heights and weights were in the normal range at birth, but the growth was retarded after birth. When they presented to the clinic, the heights of the boy (8 years old) and his sister (11 years old) were 80.0 cm (-8.2 SDS) and 96.6 cm (-6.8 SDS) respectively. They had typical appearance features of Laron syndrome such as short stature and obesity, with protruding forehead, saddle nose, large eyes, sparse and thin silky hair and high-pitched voice. They had higher basal serum GH levels and lower serum levels of IGF-I, IGFBP-3 and growth hormone binding protein (GHBP) than normal controls. The peak serum GH level after colonidine and insulin stimulations in the boy was over 350 ng/mL. After one-year rhGH treatment, the boy's height increased from 80.0 cm to 83.3 cm. The gene mutation analysis revealed that two patients had same homozygous mutation of S65H (TCA -->CCA) in exon 4, which is a novel gene mutation. It was concluded that a definite diagnosis of Laron syndrome can be made based on characteristic appearance features and serum levels of GH, IGF-I, IGFBP-3 and GHBP. The S65H mutation might be the cause of Laron syndrome in the two patients.

    Although evidence suggests an importance of genetic factors in the development of breast cancer in Taiwanese (ethnic Chinese) women, including a high incidence of early-onset and secondary contralateral breast cancer, a major breast cancer predisposition gene, BRCA1, has not been well studied in this population. In fact, the carcinogenic impacts of many genetic variants of BRCA1 are unknown and classified as variants of uncertain significance (VUS). It is therefore important to establish a method to characterize the BRCA1 VUSs and understand their role in Taiwanese breast cancer patients. Accordingly, we developed a multimodel assessment strategy consisting of a prescreening portion and a validated functional assay to study breast cancer patients with early-onset, bilateral or familial breast cancer. We found germ-line BRCA1 mutations in 11.1% of our cohort and identified one novel missense mutation, c.5191C>A. Two genetic variants were initially classified as VUSs (c.1155C>T and c.5191C>A). c.1155C>T is not predicted to be deleterious in the prescreening portion of our assessment strategy. c.5191C>A, on the other hand, causes p.T1691K, which is predicted to have high deleterious probability because of significant structural alteration, a high deleterious score in the predictive programs and, clinically, triple negative characteristics in breast tumors. This mutant is confirmed by transcription activation and yeast growth-inhibition assays. In conclusion, we show as high a prevalence of germ-line BRCA1 mutation in high-risk Taiwanese patients as in Caucasians and demonstrate a useful strategy for studying BRCA1 VUSs.

    Full Text Available Background: Congenital nystagmus (CN is characterized by conjugated, spontaneous, and involuntary ocular oscillations. It is an inherited disease and the most common inheritance pattern is X-linked CN. In this study, our aim is to identify the disease-causing mutation in a large sixth-generation Chinese family with X-linked CN. Methods: It has been reported that mutations in four-point-one, ezrin, radixin, moesin domain-containing 7 gene (FRMD7 and G protein-coupled receptor 143 gene (GPR143 account for the majority patients of X-linked nystagmus. We collected 8 ml blood samples from members of a large sixth-generation pedigree with X-linked CN and 100 normal controls. FRMD7 and GPR143 were scanned by polymerase chain reaction (PCR-based DNA sequencing assays, and multiplex PCR assays were applied to detect deletions. Results: We identified a previously unreported deletion covering 7 exons in GPR143 in a Chinese family. The heterozygous deletion from exon 3 to exon 9 of GPR143 was detected in all affected males in the family, while it was not detected in other unaffected relatives or 100 normal controls. Conclusions: This is the first report of molecular characterization in GPR143 gene in the CN family. Our results expand the spectrum of GPR143 mutations causing CN and further confirm the role of GPR143 in the pathogenesis of CN.

    Full Text Available Background. Retinitis pigmentosa (RP is an inherited retinal degenerative disease, which is clinically and genetically heterogeneous, and the inheritance pattern is complex. In this study, we have intended to study the possible association of certain genes with X-linked RP (XLRP in a Chinese family. Methods. A Chinese family with RP was recruited, and a total of seven individuals were enrolled in this genetic study. Genomic DNA was isolated from peripheral leukocytes, and used for the next generation sequencing (NGS. Results. The affected individual presented the clinical signs of XLRP. A heterozygous missense mutation (c.1555C>T, p.R519W was identified by NGS in exon 13 of the CACNA1F gene on X chromosome, and was confirmed by Sanger sequencing. It showed perfect cosegregation with the disease in the family. The mutation at this position in the CACNA1F gene of RP was found novel by database searching. Conclusion. By using NGS, we have found a novel heterozygous missense mutation (c.1555C>T, p.R519W in CACNA1F gene, which is probably associated with XLRP. The findings might provide new insights into the cause and diagnosis of RP, and have implications for genetic counseling and clinical management in this family.

    Smoking prevalence is high among limited English-proficient Chinese and Vietnamese American men, who are frequently unmotivated to quit and who underutilize smoking cessation resources. This study applied lay health worker outreach to leverage peer and family networks to promote smoking cessation among these men. We integrated qualitative formative research findings and Social Network Theory to develop a social-network family-focused intervention. In a pilot single-group trial, 15 lay health workers recruited 96 dyads (N = 192, 75% Vietnamese) of Chinese or Vietnamese male daily smokers and their family members and delivered the intervention consisting of two small group education sessions and two individual telephone calls over 2 months. At baseline, 42% of smokers were at precontemplation. At 3 months following the initiation of the intervention, 7-day and 30-day point prevalence smoking abstinence rates as reported by smokers and independently corroborated by family members were 30% and 24%, respectively. Utilization of smoking cessation resources (medication, quitline, physician's advice) increased from 2% to 60% (P Vietnamese smokers appears to be acceptable, feasible, and potentially efficacious. Findings warrant evaluation of long-term efficacy of the intervention in a larger scale randomized controlled trial. © The Author 2015.

    Developing culturally appropriate end-of-life care for Chinese elderly and families is not an endemic challenge for Hong Kong, but that of the Western countries with a noticeable trend of rising Chinese population. The particular development of Hong Kong healthcare system, which is currently the major provider of end-of-life care, makes Hong Kong a fruitful case for understanding the confluence of the West and the East cultures in end-of-life care practices. This study therefore aims at building our best practice to enhance the capacity of residential care homes in providing culturally appropriate end-of-life care. We conducted two phases of research, a questionnaire survey and a qualitative study, which respectively aims at (1) understanding the EoL care service demand and provision in RCHEs, including death facts and perceived barriers and challenges in providing quality end-of-life care in care homes, and (2) identifying the necessary organizational capacities for the 'relational personhood' to be sustained in the process of ageing and dying in residential care homes. Findings shed light on how to empower residential care homes with necessary environmental, structural and cultural-resource-related capacity for providing quality end-of-life care for Chinese elders and their families.

    2012-01-01

    This publication is intended for individuals and organizations that may be called upon to deal with the detection of and response to criminal or unauthorized acts involving nuclear or other radioactive material. It will also be useful for legislators, law enforcement agencies, government officials, technical experts, lawyers, diplomats and users of nuclear technology. This manual emphasizes the international initiatives for improving the security of nuclear and other radioactive material. However, it is recognized that effective measures for controlling the transfer of equipment, non-nuclear material, technology or information that may assist in the development of nuclear explosive devices, improvised nuclear devices (INDs) or other radiological dispersal devices (RDDs) are important elements of an effective nuclear security system. In addition, issues of personal integrity, inspection and investigative procedures are not discussed in this manual, all of which are essential elements for an effective overall security system. The manual considers a variety of elements that are recognized as being essential for dealing with incidents of criminal or unauthorized acts involving nuclear and other radioactive material. Depending on conditions in a specific State, including its legal and governmental infrastructure, some of the measures discussed will need to be adapted to suit that State's circumstances. However, much of the material can be applied directly in the context of other national programmes. This manual is divided into four main parts. Section 2 discusses the threat posed by criminal or unauthorized acts involving nuclear and other radioactive material, as well as the policy and legal bases underlying the international effort to restrain such activities. Sections 3 and 4 summarize the major international undertakings in the field. Sections 5-8 provide some basic technical information on radiation, radioactive material, the health consequences of radiation

    Myocardin (Mycd) family members function as a transcriptional cofactor for serum response factor (SRF). Dimer formation is necessary to exhibit their function, and the coiled-coil domain (CC) plays a critical role in their dimerization. We have recently revealed a detailed molecular mechanism for their Crm1 (exportin1)-mediated nuclear export. Here, we found other unique significances of the dimerization of Mycd family members. Introduction of mutations in the CC of myocardin-related transcription factor A (MRTF-A) and truncated Mycd resulted in significant decreases in their cytoplasmic localization and increases in their nuclear localization. In accordance with such subcellular localization changes, their binding to Crm1 were reduced. These results indicate that the dimerization of Mycd family members is necessary for their Crm1-mediated nuclear export. We have recently found that the N-terminal region of Mycd consisting of 128 amino acids (Mycd N128) self-associates to Mycd via the central basic domain (CB), resulting in masking the Crm1-binding site. Such self-association of MRTF-A would be unlikely. In this study, we also revealed that the dimerization of Mycd was also necessary for this self-association. Wild-type Mycd activated SRF-mediated transcription more potently than Mycd lacking the Mycd N128 (Mycd ΔN128) did. These results suggest two possible functions of the Mycd N128: 1) stabilization of Mycd dimer to enhance SRF-mediated transcription and 2) positive regulation of the transactivation ability of Mycd. These findings provide a new insight into the functional regulation of Mycd family members.

    Usher syndrome type II (USH2) is the most common form of Usher syndrome, an autosomal recessive disorder characterized by moderate to severe hearing loss, postpuberal onset of retinitis pigmentosa (RP), and normal vestibular function. Mutations in the USH2A gene have been shown to be responsible for most cases of USH2. To further elucidate the role of USH2A in USH2, mutation screening was undertaken in three Chinese families with USH2. Three unrelated Chinese families, consisting of six patients and 10 unaffected relatives, were examined clinically, and 100 normal Chinese individuals served as controls. Genomic DNA was extracted from the venous blood of all participants. The coding region (exons 2-72), including the intron-exon boundary of USH2A, was amplified by polymerase chain reaction (PCR). The PCR products amplified from the three probands were analyzed using direct sequencing to screen sequence variants. Whenever substitutions were identified in a patient, restriction fragment length polymorphism analysis, or single strand conformation polymorphism analysis was performed on all available family members and the control group. Fundus examination revealed typical fundus features of RP, including narrowing of the vessels, bone-speckle pigmentation, and waxy optic discs. The ERG wave amplitudes of three probands were undetectable. Audiometric tests indicated moderate to severe sensorineural hearing impairment. Vestibular function was normal. Five novel mutations (one small insertion, one small deletion, one nonsense, one missense, and one splice site) were detected in three families after sequence analysis of USH2A. Of the five mutations, four were located in exons 22-72, specific to the long isoform of USH2A. The mutations found in our study broaden the spectrum of USH2A mutations. Our results further indicate that the long isoform of USH2A may harbor even more mutations of the USH2A gene.

    To explore the separate and combined effects of work and family stress on menstrual disorders and fibrocystic changes in Chinese working women. Data were obtained from a cross-sectional study of 1,642 female railway workers. The Effort-Reward Imbalance Questionnaire and Family Stress Scale were used to measure work stress and family stress, respectively; the menstrual and breast conditions were evaluated by gynecologic interview and a medical examination. Multivariate log-binomial regression was performed to analyze the associations. Menstrual disorders were found in 59.3% of female workers, and 54.8% had fibrocystic changes. The risk of menstrual disorders was significantly elevated with respect to work and family stress. The highest risk was found in the group with combined exposure to both work and family stress (RR with 95% CI 1.33 (1.18-1.49)). No significant association between stress and fibrocystic changes was observed. Menstrual disorders were associated with stress from work and family life, but not fibrocystic changes, in working women. Tailored intervention measures reducing the burden of stressful psychosocial work and family environment are needed to improve women's reproductive well-being.

    Nuclear receptors are a superfamily of transcription factors important in key biological, developmental and reproductive processes. Several of these receptors are ligand- activated and through their ability to bind endogenous and exogenous ligands, are potentially vulnerable to xenobiotics. Molluscs are key ecological species in defining aquatic and terrestrial habitats and are sensitive to xenobiotic compounds in the environment. However, the understanding of nuclear receptor presence, function and xenobiotic disruption in the phylum Mollusca is limited. Here, forty-three nuclear receptor sequences were mined from the genome of the Pacific oyster, Crassostrea gigas. They include members of NR0-NR5 subfamilies, notably lacking any NR6 members. Phylogenetic analyses of the oyster nuclear receptors have been conducted showing the presence of a large novel subfamily group not previously reported, which is named NR1P. Homologues to all previous identified nuclear receptors in other mollusc species have also been determined including the putative heterodimer partner retinoid X receptor, estrogen receptor and estrogen related receptor. C. gigas contains a highly diverse set of nuclear receptors including a novel NR1 group, which provides important information on presence and evolution of this transcription factor superfamily in invertebrates. The Pacific oyster possesses two members of NR3, the sex steroid hormone receptor analogues, of which there are 9 in humans. This provides increasing evidence that steroid ligand specific expansion of this family is deuterostome specific. This new knowledge on divergence and emergence of nuclear receptors in C. gigas provides essential information for studying regulation of molluscan gene expression and the potential effects of xenobiotics.

    Using a sample of 156 Chinese children aged 2-3 years and their parents, this study examined the effects of socio-economic status, specifically family income and parental education, on the children's internalizing and externalizing psychopathology and whether these effects were mediated by mother-child and father-child conflict. Results indicated that family income, maternal education and paternal education all negatively predicted externalizing symptoms. Income also negatively predicted internalizing symptoms among boys but not girls. Maternal education negatively predicted internalizing symptoms among girls but not boys. The effects of income on psychopathology were fully mediated by mother-child and father-child conflict. In contrast, the effects of education were not mediated or only partially mediated by conflict. Findings are discussed in the framework of the family stress model. © 2013 International Union of Psychological Science.

    The familial transthyretin (TTR) amyloidosis (FTA) demonstrates variable penetrance of clinical features associated with mutations in the plasma thyroid hormone-binding protein TTR gene. The purpose of this study was to assess the ocular features, to analyze vitreous and serum vascular endothelial growth factor (VEGF) levels, and to identify the genetic defect in a Chinese family with TTR FTA. The pedigree of interest was a three-generation family with eleven members. The primary ocular signs were vitreous opacities, beginning from the third or fourth decade, accompanied by retinal vasculitis, hemorrhages, and widespread pinpoint deposits in the peripheral retina. Two patients underwent vitrectomy with marked improvement of visual acuity postoperatively. Vitreous and serum samples for VEGF were analyzed with an enzyme-linked immunosorbent assay (ELISA). Forty-eight healthy adult volunteers were enrolled as a control group for the analysis of serum VEGF. Eight subjects who underwent vitrectomy for a macular epiretinal membrane or macular hole were enrolled as control for the analysis of vitreous VEGF. Both serum and vitreous VEGF levels of patients were raised compared to that of controls. Venous blood was collected from family members and the genomic DNA was extracted. All exons and exon-intron boundaries of the TTR gene were sequenced. A previously-described pathogenic transversion in exon 2 (c.G106C, p.Ala36Pro) was identified. Within this family eight individuals were confirmed as affected. In conclusion, a Chinese family with TTR Ala36Pro associated FTA is characterized by early ocular involvement. Widespread pinpoint lesions indicate RPE lesions caused by TTR deposition. FTA is associated with increased VEGF levels, both in serum and vitreous. Copyright © 2013 Elsevier Ltd.

  17. Nuclear localization of Src-family tyrosine kinases is required for growth factor-induced euchromatinization

    Src-family kinases (SFKs), which participate in various signaling events, are found at not only the plasma membrane but also several subcellular compartments, including the nucleus. Nuclear structural changes are frequently observed during transcription, cell differentiation, senescence, tumorigenesis, and cell cycle. However, little is known about signal transduction in the alteration of chromatin texture. Here, we develop a pixel imaging method for quantitatively evaluating chromatin structural changes. Growth factor stimulation increases euchromatic hypocondensation and concomitant heterochromatic hypercondensation in G 1 phase, and the levels reach a plateau by 30 min, sustain for at least 5 h and return to the basal levels after 24 h. Serum-activated SFKs in the nucleus were more frequently detected in the euchromatin areas than the heterochromatin areas. Nuclear expression of kinase-active SFKs, but not unrelated Syk kinase, drastically increases both euchromatinization and heterochromatinization in a manner dependent on the levels of nuclear tyrosine phosphorylation. However, growth factor stimulation does not induce chromatin structural changes in SYF cells lacking SFKs, and reintroduction of one SFK member into SYF cells can, albeit insufficiently, induce chromatin structural changes. These results suggest that nuclear tyrosine phosphorylation by SFKs plays an important role in chromatin structural changes upon growth factor stimulation.

    Family food choice is complex with a number of people within the family sharing food choice and preparation responsibilities. Differences in dietary behaviours also exist between various ethnic groups worldwide, and are apparent within multicultural nations such as Australia. This study examined the intergenerational transmission of eating behaviour through semi-structured family interviews with 27 three generation families (Anglo-Australian: n = 11, Chinese-Australian: n = 8, Italian-Australian: n = 8; N = 114). The influence of generation (grandparent, parent, child), role (grandmother, grandfather, mother, father, daughter, son), and ethnic background were considered. Thematic analysis identified that regardless of ethnic background, grandmothers and mothers dominated family food choice decisions even in families where fathers were primarily responsible for the preparation of family meals. The women in each generation influenced fruit and vegetable intake by controlling purchasing decisions (e.g., by shopping for food or editing family grocery shopping lists), insisting on consumption, monitoring and reminding, utilizing food as a prerequisite for conditional treats (e.g., eating fruit before being allowed snacks), instigating and enforcing food rules (e.g., fast food only on weekends), and restricting others' food choices. Grandparents and children shared a relationship that skipped the parent generation and influenced dietary behaviours bi-directionally. These findings have implications for the delivery of dietary health messages used in disease prevention interventions designed to successfully reach culturally and linguistically diverse populations and all members of multigenerational families.

    DNA copy number variants (CNVs) that alter the copy number of a particular DNA segment in the genome play an important role in human phenotypic variability and disease susceptibility. A number of CNVs overlapping with genes have been shown to confer risk to a variety of human diseases thus highlighting the relevance of addressing the variability of CNVs at a higher resolution. So far, it has not been possible to deterministically infer the allelic composition of different haplotypes present within the CNV regions. We have developed a novel computational method, called PiCNV, which enables to resolve the haplotype sequence composition within CNV regions in nuclear families based on SNP genotyping microarray data. The algorithm allows to i) phase normal and CNV-carrying haplotypes in the copy number variable regions, ii) resolve the allelic copies of rearranged DNA sequence within the haplotypes and iii) infer the heritability of identified haplotypes in trios or larger nuclear families. To our knowledge this is the first program available that can deterministically phase null, mono-, di-, tri- and tetraploid genotypes in CNV loci. We applied our method to study the composition and inheritance of haplotypes in CNV regions of 30 HapMap Yoruban trios and 34 Estonian families. For 93.6% of the CNV loci, PiCNV enabled to unambiguously phase normal and CNV-carrying haplotypes and follow their transmission in the corresponding families. Furthermore, allelic composition analysis identified the co-occurrence of alternative allelic copies within 66.7% of haplotypes carrying copy number gains. We also observed less frequent transmission of CNV-carrying haplotypes from parents to children compared to normal haplotypes and identified an emergence of several de novo deletions and duplications in the offspring.

    Heat shock transcription factors (Hsfs), which act as important transcriptional regulatory proteins in eukaryotes, play a central role in controlling the expression of heat-responsive genes. At present, the genomes of Chinese white pear ('Dangshansuli') and five other Rosaceae fruit crops have been fully sequenced. However, information about the Hsfs gene family in these Rosaceae species is limited, and the evolutionary history of the Hsfs gene family also remains unresolved. In this study, 137 Hsf genes were identified from six Rosaceae species (Pyrus bretschneideri, Malus × domestica, Prunus persica, Fragaria vesca, Prunus mume, and Pyrus communis), 29 of which came from Chinese white pear, designated as PbHsf. Based on the structural characteristics and phylogenetic analysis of these sequences, the Hsf family genes could be classified into three main groups (classes A, B, and C). Segmental and dispersed duplications were the primary forces underlying Hsf gene family expansion in the Rosaceae. Most of the PbHsf duplicated gene pairs were dated back to the recent whole-genome duplication (WGD, 30-45 million years ago (MYA)). Purifying selection also played a critical role in the evolution of Hsf genes. Transcriptome data demonstrated that the expression levels of the PbHsf genes were widely different. Six PbHsf genes were upregulated in fruit under naturally increased temperature. A comprehensive analysis of Hsf genes was performed in six Rosaceae species, and 137 full length Hsf genes were identified. The results presented here will undoubtedly be useful for better understanding the complexity of the Hsf gene family and will facilitate functional characterization in future studies.

    A group of mesh-based and age-dependent family phantoms for Chinese populations were developed in this study. We implemented a method for deforming original RPI-AM and RPI-AF models into phantoms of different ages: 5, 10 ,15 and adult. More than 120 organs for each model were processed to match with the values of the Chinese reference parameters within 0.5%. All of these phantoms were then converted to voxel format for Monte Carlo simulations. Dose coefficients for adult models were counted to compare with those of RPI-AM and RPI-AF. The results show that there are significant differences between absorbed doses of RPI phantoms and these of our adult phantoms at low energies. Comparisons for the dose coefficients among different ages and genders were also made. it was found that teenagers receive more radiation doses than adults under the same irradiation condition. This set of phantoms can be utilized to estimate dosimetry for Chinese population for radiation protection, medical imaging, and radiotherapy.

    Full Text Available X-linked hearing impairment is the rarest form of genetic hearing loss (HL and represents only a minor fraction of all cases. The aim of this study was to investigate the cause of X-linked inherited sensorineural HL in a four-generation Chinese family. A novel duplication variant (c.217dupA, p.Ile73Asnfs*5 in SMPX was identified by whole-exome sequencing. The frameshift mutation predicted to result in the premature truncation of the SMPX protein was co-segregated with the HL phenotype and was absent in 295 normal controls. Subpopulation screening of the coding exons and flanking introns of SMPX was further performed for 338 Chinese patients with nonsydromic HL by Sanger sequencing, and another two potential causative substitutions (c.238C>A and c.55A>G in SMPX were identified in additional sporadic cases of congenital deafness. Collectively, this study is the first to report the role of SMPX in Chinese population and identify a novel frameshift mutation in SMPX that causes not only nonsyndromic late-onset progressive HL, but also congenital hearing impairment. Our findings extend the mutation and phenotypic spectrum of the SMPX gene.

    The study purpose was to examine the validities and reliabilities of the Chinese-versions Frommelt Attitudes Toward Care of the Dying Scale (Attitudes Scale) and Caregiving Behaviors Scale for End-of-Life Patients and Families (Behaviors Scale). The scales were tested in a convenience sample of 318 nurses with ≥6 months work experience at three hospitals. Cronbach's alphas of the Attitudes and Behaviors Scales were .90 and .96, respectively. Each scale had Kaiser-Meyer-Olkin index >.85 and Bartlett's test of sphericity >4000 ( p < .001). Attitudes Scale loaded on three factors: respecting and caring for dying patients and families, avoiding care of the dying, and involving patients and families in end-of-life care. The Behaviors Scale loaded on two factors: supporting dying patients and families, and helping families cope with grief. Factor loadings for both scales were ≥.49. Both Attitudes and Behaviors Scales are reliable and valid for evaluating nurses' attitudes and caregiving behaviors for the dying.

    Short interspersed nuclear elements (SINEs) are non-autonomous transposable elements which are propagated by retrotransposition and constitute an inherent part of the genome of most eukaryotic species. Knowledge of heterogeneous and highly abundant SINEs is crucial for de novo (or improvement of) annotation of whole genome sequences. We scanned Poaceae genome sequences of six important cereals (Oryza sativa, Triticum aestivum, Hordeum vulgare, Panicum virgatum, Sorghum bicolor, Zea mays) and Brachypodium distachyon to examine the diversity and evolution of SINE populations. We comparatively analyzed the structural features, distribution, evolutionary relation and abundance of 32 SINE families and subfamilies within grasses, comprising 11 052 individual copies. The investigation of activity profiles within the Poaceae provides insights into their species-specific diversification and amplification. We found that Poaceae SINEs (PoaS) fall into two length categories: simple SINEs of up to 180 bp and dimeric SINEs larger than 240 bp. Detailed analysis at the nucleotide level revealed that multimerization of related and unrelated SINE copies is an important evolutionary mechanism of SINE formation. We conclude that PoaS families diversify by massive reshuffling between SINE families, likely caused by insertion of truncated copies, and provide a model for this evolutionary scenario. Twenty-eight of 32 PoaS families and subfamilies show significant conservation, in particular either in the 5' or 3' regions, across Poaceae species and share large sequence stretches with one or more other PoaS families. © 2017 The Authors The Plant Journal © 2017 John Wiley & Sons Ltd.

    This study profiles the family-directed anger of traumatized Cambodian refugees, all survivors of the Pol Pot genocide (1975-1979), who were patients at a psychiatric clinic in Lowell, MA, USA. We focus on the nuclear family (NF) unit, the NF unit defined as the patient's "significant other" (i.e. spouse or boyfriend/girlfriend) and children. Survey data were collected from a convenience sample of 143 Cambodian refugee patients from October 2006 to August 2007. The study revealed that 48% (68/143) of the patients had anger directed toward a NF member in the last month, with anger directed toward children being particularly common (64 of the 143 patients, or 49% [64/131] of the patients with children). NF-type anger was severe, for example, almost always resulting in somatic arousal (e.g., causing palpitations in 91% [62/68] of the anger episodes) and often in trauma recall and fears of bodily dysfunction. Responses to open-ended questions revealed the causes of anger toward a significant other and children, the content of anger-associated trauma recall, and what patients did to gain relief from anger. A type of cultural gap, namely, a linguistic gap (i.e., the parent's lack of English language skills and the child's lack of Khmer language skills), seemingly played a role in generating conflict and anger. NF-type anger was associated with PTSD presence. The effect of anger on PTSD severity resulted in part from anger-associated trauma recall and fears of bodily dysfunction, with 54% of the variance in PTSD severity explained by that regression model. The study: 1) suggests that among traumatized refugees, family-related anger is a major clinical concern; 2) illustrates how family-related anger may be profiled and investigated in trauma-exposed populations; and 3) gives insights into how family-related anger is generated in such populations.

    Full Text Available Nail patella syndrome (NPS is an autosomal dominant disorder characterized by nail malformations, patellar apoplasia, or patellar hypoplasia. Mutations within the LMX1B gene are found in 85% of families with NPS; thus, this gene has been characterized as the causative gene of NPS. In this study, we identified a heterozygous microdeletion of the entire LMX1B gene using multiplex ligation-dependent probe amplification (MLPA in a Chinese family with NPS. The determination of the deletion breakpoints by Illumina genome-wide DNA analysis beadchip showed that the deletion was located in chromosome 9q33.3 and spanned about 0.66 Mb in size. This heterozygous deletion provides strong evidence for haploinsufficiency as the pathogenic mechanism of NPS.

  14. Over-expression of SR-cyclophilin, an interaction partner of nuclear pinin, releases SR family splicing factors from nuclear speckles

    Pre-mRNA splicing takes place within a dynamic ribonucleoprotein particle called the spliceosome and occurs in an ordered pathway. Although it is known that spliceosome consists of five small nuclear RNAs and at least 50 proteins, little is known about how the interaction among the proteins changes during splicing. Here we identify that SR-cyp, a Moca family of nuclear cyclophilin, interacts and colocalizes with nuclear pinin (pnn), a SR-related protein involving in pre-mRNA splicing. Nuclear pnn interacts with SR-cyp via its C-terminal RS domain. Upon SR-cyp over-expression, however, the subnuclear distribution of nuclear pnn is altered, resulting in its redistribution from nuclear speckles to a diffuse nucleoplasmic form. The diffuse subnuclear distribution of nuclear pnn is not due to epitope masking, accelerated protein turnover or post-translational modification. Furthermore, we find that SR-cyp regulates the subnuclear distribution of other SR family proteins, including SC35 and SRm300, in a similar manner as it does on nuclear pnn. This result is significant because it suggests that SR-cyp plays a general role in modulating the distribution pattern of SR-like and SR proteins, similar to that of Clk (cdc2-like kinase)/STY on SR family splicing factors. SR-cyp might direct its effect via either alteration of protein folding/conformation or of protein-protein interaction and thus may add another control level of regulation of SR family proteins and modification of their functions

    Pacific Northwest Laboratory (PNL) has measured the radionuclide concentration of short-lived debris from a radioactive cloud, produced by a nuclear weapons test conducted by the People's Republic of China on March 15, 1978. Analysis with a 40 cfm Sierra impactor showed that a large portion of the radioactivity was associated with relatively large particles. Surface air samples showed significant concentrations of 124 Sb. Samples of rain water from New York State showed that radioactivity arrived on the east coast at about the same time as peak debris levels were observed on the west coast. Highest concentrations of 131 I occurred along the Washington State--Canadian border

    Depressive symptoms have been in the limelight for many kinds of people, but few studies have explored positive resources for combating depressive symptoms among Chinese nurses. The purpose of this study is to explore the association between work-family conflict (WFC) and depressive symptoms among Chinese female nurses, along with the mediating and moderating role of psychological capital (PsyCap) in this relationship. This cross-sectional study was completed during the period of September and October 2013. A questionnaire that consisted of the Center for Epidemiologic Studies Depression Scale, the Work-Family Conflict scale and the Psychological Capital Questionnair scale was distributed to nurses in Shenyang, China. A total of 824 individuals (effective response rate: 74.9%) participated. Asymptotic and resampling strategies explored the mediating role of PsyCap in the relationship between WFC and depressive symptoms. Hierarchical linear regression analyses were performed to explore the moderating role of PsyCap. Both WFC and family-work conflict (FWC) were positively related with depressive symptoms. PsyCap positively moderated the relationship of WFC with depressive symptoms. Self-efficacy and hope positively moderated the relationship of WFC with depressive symptoms. PsyCap partially mediated the relationship of FWC with depressive symptoms. Hope and optimism partially mediated the relationship of FWC with depressive symptoms. Work-family conflict, as the risk factor of depressive symptoms, can increase nurses’ depressive symptoms, and PsyCap is a positive resource to combat nurses’ depressive symptoms. PsyCap can aggravate the effects of WFC on depressive symptoms and FWC can impact PsyCap to increase nurses’ depressive symptoms. PMID:26075725

    Accumulating evidence has implied that serotonin system dysfunction may be involved in the etiology of anorexia nervosa (AN). Serotonin-transporter-linked promoter region (5-HTTLPR) polymorphism is the genetic variant coding for the serotonin transporter and has a modulatory effect on its expression. This study aimed to investigate the possible association between the 5-HTTLPR and the susceptibility and severity of AN in Han Chinese using a case-control (255 patients and 351 controls) and family based study (198 trios). Eating disorder examination was used to measure the severity of AN behavioral symptoms. For the case-control study, the 5-HTTLPR showed significant association with AN in our sample (genotypic P = 0.03). The frequency of S allele was significantly higher in patients than that in controls (OR = 1.38, 95%CI: 1.06-1.79, P = 0.017). For the family-based study, the S allele of 5-HTTLPR was preferentially transmitted rather than non-transmitted from the parents to affected offspring (P = 0.013). The results of ANCOVA test revealed no significant association between the 5-HTTLPR polymorphism and severity of AN. Our findings suggested that 5-HTTLPR is able to confer susceptibility to AN in Han Chinese.

The results of ANCOVA test revealed no significant association between the 5-HTTLPR polymorphism and severity of AN. Our findings suggested that 5-HTTLPR is able to confer susceptibility to AN in Han Chinese.

    Purpose. To investigate the role of alpha2-HS glycoprotein (AHSG) gene on bone mineral density (BMD) variation. Methods. A total of 665 subjects from 157 Caucasian nuclear families were genotyped at the AHSG NlaIII, SacI sites. The association and linkage between the single SNP markers and haplotypes constructed by two markers in this gene and BMDs at the spine and hip were determined by using quantitative transmission disequilibrium test (QTDT). Results. Significant within-family associations were obtained for spine BMD at both of studied markers (P = 0.036 and 0.005 at the NlaIII and SacI sites, respectively). Significant (P = 0.008 at the NlaIII locus) (P = 0.004 at the SacI locus) total associations at spine BMD were detected. Haplotype analyses confirmed those within-family and total association. Conclusions. These data suggest the polymorphisms in the AHSG gene may have effects on BMD variation in Caucasian population

    Full Text Available Abstract Background Social support is strongly implicated in the aetiology of perinatal mental disorder: particularly the quality of the marital and family environment. Family structures are important under-researched potential modifiers. Turkey offers particular advantages for research in this area because of long-standing coexistence of Western and Middle Eastern family structures. We aimed to investigate associations between the quality of key relationships and depression in women in their third trimester of pregnancy, and the extent to which these associations were modified by family structure. Method Women attending antenatal clinics in their third trimester were recruited from urban and rural settings in Ankara. A nuclear family structure was defined as a wife and husband living alone or with their children in the same household, whereas a traditional/extended family structure was defined if another adult was living with the married couple in the same household. Depression was ascertained using the Edinburgh Postnatal Depression Scale (EPDS and social support was assessed by the Close Person Questionnaire with respect to the husband, mother and mother-in-law. Social support was compared between participants with/without case-level depression on the EPDS in linear regression models adjusted for relevant covariates, then stratified by nuclear/traditional family structure. Results Of 772 women approached, 751 (97.3% participated and 730 (94.6% had sufficient data for this analysis. Prevalence of case-level depression was 33.1% and this was associated with lower social support from all three family members but not with traditional/nuclear family structure. The association between depression and lower emotional support from the husband was significantly stronger in traditional compared to nuclear family environments. Conclusions Lower quality of relationships between key family members was strongly associated with third trimester depression

    Waardenburg syndrome type II (WS2) is associated with syndromic deafness. A subset of WS2, WS2A, accounting for approximately 15% of patients, is attributed to mutations in the microphthalmia-associated transcription factor (MITF) gene. We examined the genetic basis of WS2 in a large Chinese family. All 9 exons of the MITF gene, the single coding exon (exon 2) of the most common hereditary deafness gene GJB2 and the mitochondrial DNA (mtDNA) 12S rRNA were sequenced. A novel heterozygous mutation c.[742_743delAAinsT;746_747delCA] in exon 8 of the MITF gene co-segregates with WS2 in the family. The MITF mutation results in a premature termination codon and a truncated MITF protein with only 247 of the 419 wild type amino acids. The deaf proband had this MITF gene heterozygous mutation as well as a c.[109G>A]+[235delC] compound heterozygous pathogenic mutation in the GJB2 gene. No pathogenic mutation was found in mtDNA 12S rRNA in this family. Thus, a novel compound heterozygous mutation, c.[742_743delAAinsT;746_747delCA] in MITF exon 8 was the key genetic reason for WS2 in this family, and a digenic effect of MITF and GJB2 genes may contribute to deafness of the proband.

    The evaluations on institutionalized care facilities from family members, after their loved ones moved into such services, are very different from culture to culture, family to family and person to person. According to a recent survey in the United States and China, it is found that different cultures and the different health conditions of the residents strongly influence family member's viewpoints on institutionalized care services. It is also found that the availability of the institutionalized care facilities plays a significant role, which strongly affects family members' evaluations on nursing home services.

    To explore the association between maternal intimate partner abuse (IPA) and their children's health-related quality of life (HRQOL) and behavioural problem, and to establish a mediation model and investigate the mediating role of mothers' HRQOL on this association. A cross-sectional study was conducted on 197 mothers of 227 children (112 boys and 115 girls) from low-income Chinese families. The mothers were asked to complete the 5-item abuse assessment screen questionnaire for the presence of IPA, the Chinese (Hong Kong) version of 12-item Short-Form Health Survey (SF-12) for their HRQOL and a structured socio-demographics questionnaire. One of the parents completed the Child Health Questionnaire-Parent Form-50 (CHQ-PF50) and the strengths and difficulties questionnaire (SDQ) to report on their children's HRQOL and behavioural problems, respectively. The mediating effect of the maternal HRQOL on the relationship between maternal IPA status and their children's behavioural problems and HRQOL was tested using Baron and Kenney's multistage regression approach and bootstrapping method. Thirty-five of the 197 mothers reported IPA (17.8%). Children whose mothers had experienced IPA had lower scores in the CHQ-PF50 mental health, parental impact-emotional, family activities and family cohesion subscales, and the psychosocial summary score compared to children of mothers who reported no IPA; they also had more emotional, conduct and hyperactivity/inattention problems and higher total difficulties scores measured by the SDQ. Maternal mental HRQOL was a mediator on the relationship between maternal IPA status and their children's behavioural problems and psychosocial HRQOL. IPA experienced by mothers had significant negative impacts on their children's HRQOL and behaviours, which was mediated by maternal mental HRQOL.

    Classical nuclear localization signal (NLS) dependent nuclear import is carried out by a heterodimer of importin alpha and importin beta. NLS cargo is recognized by importin alpha, which is bound by importin beta. Importin beta mediates translocation of the complex through the central channel of the nuclear pore, and upon reaching the nucleus, RanGTP binding to importin beta triggers disassembly of the complex. To date, six importin alpha family members, encoded by separate genes, have been described in humans. We sequenced and characterized a seventh member of the importin alpha family of transport factors, karyopherin alpha 7 (KPNA7), which is most closely related to KPNA2. The domain of KPNA7 that binds Importin beta (IBB) is divergent, and shows stronger binding to importin beta than the IBB domains from of other importin alpha family members. With regard to NLS recognition, KPNA7 binds to the retinoblastoma (RB) NLS to a similar degree as KPNA2, but it fails to bind the SV40-NLS and the human nucleoplasmin (NPM) NLS. KPNA7 shows a predominantly nuclear distribution under steady state conditions, which contrasts with KPNA2 which is primarily cytoplasmic. KPNA7 is a novel importin alpha family member in humans that belongs to the importin alpha2 subfamily. KPNA7 shows different subcellular localization and NLS binding characteristics compared to other members of the importin alpha family. These properties suggest that KPNA7 could be specialized for interactions with select NLS-containing proteins, potentially impacting developmental regulation.

  13. Interleukin-33 (IL-33): A nuclear cytokine from the IL-1 family.

    2018-01-01

    Interleukin-33 (IL-33) is a tissue-derived nuclear cytokine from the IL-1 family abundantly expressed in endothelial cells, epithelial cells and fibroblast-like cells, both during homeostasis and inflammation. It functions as an alarm signal (alarmin) released upon cell injury or tissue damage to alert immune cells expressing the ST2 receptor (IL-1RL1). The major targets of IL-33 in vivo are tissue-resident immune cells such as mast cells, group 2 innate lymphoid cells (ILC2s) and regulatory T cells (Tregs). Other cellular targets include T helper 2 (Th2) cells, eosinophils, basophils, dendritic cells, Th1 cells, CD8 + T cells, NK cells, iNKT cells, B cells, neutrophils and macrophages. IL-33 is thus emerging as a crucial immune modulator with pleiotropic activities in type-2, type-1 and regulatory immune responses, and important roles in allergic, fibrotic, infectious, and chronic inflammatory diseases. The critical function of IL-33/ST2 signaling in allergic inflammation is illustrated by the fact that IL33 and IL1RL1 are among the most highly replicated susceptibility loci for asthma. In this review, we highlight 15 years of discoveries on IL-33 protein, including its molecular characteristics, nuclear localization, bioactive forms, cellular sources, mechanisms of release and regulation by proteases. Importantly, we emphasize data that have been validated using IL-33-deficient cells. © 2017 The Authors. Immunological Reviews Published by John Wiley & Sons Ltd.

  14. Nuclear functions and subcellular trafficking mechanisms of the epidermal growth factor receptor family

    Science.gov (United States)

    2012-01-01

    Accumulating evidence suggests that various diseases, including many types of cancer, result from alteration of subcellular protein localization and compartmentalization. Therefore, it is worthwhile to expand our knowledge in subcellular trafficking of proteins, such as epidermal growth factor receptor (EGFR) and ErbB-2 of the receptor tyrosine kinases, which are highly expressed and activated in human malignancies and frequently correlated with poor prognosis. The well-characterized trafficking of cell surface EGFR is routed, via endocytosis and endosomal sorting, to either the lysosomes for degradation or back to the plasma membrane for recycling. A novel nuclear mode of EGFR signaling pathway has been gradually deciphered in which EGFR is shuttled from the cell surface to the nucleus after endocytosis, and there, it acts as a transcriptional regulator, transmits signals, and is involved in multiple biological functions, including cell proliferation, tumor progression, DNA repair and replication, and chemo- and radio-resistance. Internalized EGFR can also be transported from the cell surface to several intracellular compartments, such as the Golgi apparatus, the endoplasmic reticulum, and the mitochondria, in addition to the nucleus. In this review, we will summarize the functions of nuclear EGFR family and the potential pathways by which EGFR is trafficked from the cell surface to a variety of cellular organelles. A better understanding of the molecular mechanism of EGFR trafficking will shed light on both the receptor biology and potential therapeutic targets of anti-EGFR therapies for clinical application.

    Nuclear receptor coactivators (NCOAs) are multifunctional transcriptional coregulators for a growing number of signal-activated transcription factors. The members of the p160 family (NCOA1/2/3) are increasingly recognized as essential and nonredundant players in a number of physiological processes. In particular, accumulating evidence points to the pivotal roles that these coregulators play in inflammatory and metabolic pathways, both under homeostasis and in disease. Given that chronic inflammation of metabolic tissues ("metainflammation") is a driving force for the widespread epidemic of obesity, insulin resistance, cardiovascular disease, and associated comorbidities, deciphering the role of NCOAs in "normal" vs "pathological" inflammation and in metabolic processes is indeed a subject of extreme biomedical importance. Here, we review the evolving and, at times, contradictory, literature on the pleiotropic functions of NCOA1/2/3 in inflammation and metabolism as related to nuclear receptor actions and beyond. We then briefly discuss the potential utility of NCOAs as predictive markers for disease and/or possible therapeutic targets once a better understanding of their molecular and physiological actions is achieved.

  16. "The Taming of the Shrew": authority and love at the origin of the modern nuclear family

    Full Text Available The lesson on William Shakespeare’s The Taming of the Shrew was written on occasion of the day against the astonishing number of women murdered by men especially men who pretended to love them. This phenomenon is not to be associated to a sort of archaic culture, but, on the contrary, it is related to modernity. In fact, violence and conflicts in a heterosexual couple come explicitly to the fore with and after the institution of the patriarchal nuclear family which at the origins of modernity posits love as the motivation of marriage and the formation of a family. Shakespeare and the Elizabethan theatre face the question both in tragedies and in comedies as in the case of The Taming of the Shrew where the shrew’s final monologue problematically sounds as the manifesto of the acknowledgment of the inferiority of women and so of the husband’s right to the woman’s subjection to her husband.

    Systemic sclerosis (SSc) is a connective tissue disease of unknown etiology and unclear pathogenesis. Evaluation of the activation of nuclear factor κB (NF-κB) family genes IκBα, p50, p52, p65, and c-Rel, potentially involved in the regulation of immunity, inflammation, angiogenesis, and tissue remodeling in SSc, was carried out. The study included 19 patients with limited SSc, 11 patients with early SSc, and 10 healthy persons constituting the control group. Real-time QRT-PCR was used to evaluate the mRNAs in peripheral blood samples. The patients with early SSc showed a decrease in transcriptional activity of IκBα inhibitor and c-Rel subunit. Transcriptional activity decrease in the other patients with limited SSc included genes encoding c-Rel and p50, subunits of NF-κB factor. Deregulation of intracellular signal transduction by NF-κB takes place at the beginning of SSc and in its fibrosis stage. Associations between clinical variables and NF-κB related gene expression as well as the activation of NF-κB family members in SSc patients should be addressed in future studies. © 2017 by the Association of Clinical Scientists, Inc.

    In Asia, young-onset type 2 diabetes (YOD) is characterized by obesity and increased risk for cardiovascular disease (CVD). In a genome-wide association study (GWAS) of 99 Chinese obese subjects with familial YOD diagnosed before 40-year-old and 101 controls, the T allele of rs1408888 in intron 1 of DACH1(Dachshund homolog 1) was associated with an odds ratio (OR) of 2.49(95% confidence intervals:1.57-3.96, P = 8.4 × 10(-5)). Amongst these subjects, we found reduced expression of DACH1 in peripheral blood mononuclear cells (PBMC) from 63 cases compared to 65 controls (P = 0.02). In a random cohort of 1468 cases and 1485 controls, amongst top 19 SNPs from GWAS, rs1408888 was associated with type 2 diabetes with a global P value of 0.0176 and confirmation in a multiethnic Asian case-control cohort (7370/7802) with an OR of 1.07(1.02-1.12, P(meta)  = 0.012). In 599 Chinese non-diabetic subjects, rs1408888 was linearly associated with systolic blood pressure and insulin resistance. In a case-control cohort (n = 953/953), rs1408888 was associated with an OR of 1.54(1.07-2.22, P = 0.019) for CVD in type 2 diabetes. In an autopsy series of 173 non-diabetic cases, TT genotype of rs1408888 was associated with an OR of 3.31(1.19-9.19, P = 0.0214) and 3.27(1.25-11.07, P = 0.0184) for coronary heart disease (CHD) and coronary arteriosclerosis. Bioinformatics analysis revealed that rs1408888 lies within regulatory elements of DACH1 implicated in islet development and insulin secretion. The T allele of rs1408888 of DACH1 was associated with YOD, prediabetes and CVD in Chinese.
