    Aiming at the anti-poverty outline of China and the human-environment sustainable development, we propose a multidimensional poverty measure and analysis methodology for measuring the poverty-stricken counties and their contributing factors. We build a set of multidimensional poverty indicators with Chinese characteristics, integrating A-F double cutoffs, dimensional aggregation and decomposition approach, and GIS spatial analysis to evaluate the poor's multidimensional poverty characteristics under different geographic and socioeconomic conditions. The case study from 11 counties of Hechi City shows that, firstly, each county existed at least four respects of poverty, and overall the poverty level showed the spatial pattern of surrounding higher versus middle lower. Secondly, three main poverty contributing factors were unsafe housing, family health and adults' illiteracy, while the secondary factors include fuel type and children enrollment rate, etc., generally demonstrating strong autocorrelation; in terms of poverty degree, the western of the research area shows a significant aggregation effect, whereas the central and the eastern represent significant spatial heterogeneous distribution. Thirdly, under three kinds of socioeconomic classifications, the intra-classification diversities of H, A, and MPI are greater than their inter-classification ones, while each of the three indexes has a positive correlation with both the rocky desertification degree and topographic fragmentation degree, respectively. This study could help policymakers better understand the local poverty by identifying the poor, locating them and describing their characteristics, so as to take differentiated poverty alleviation measures according to specific conditions of each county.

    One of the goals of this study was to learn the coverage, safety and logistics of a mass vaccination campaign against typhoid fever in children and adults using locally produced typhoid Vi polysaccharide (PS) and group A meningococcal PS vaccines in southern China. The vaccination campaign targeted 118,588 persons in Hechi, Guangxi Province, aged between 5 to 60 years, in 2003. The study area was divided into 107 geographic clusters, which were randomly allocated to receive one of the single-dose parenteral vaccines. All aspects regarding vaccination logistics, feasibility and safety were documented and systematically recorded. Results of the logistics, feasibility and safety are reported. The campaign lasted 5 weeks and the overall vaccination coverage was 78%. On average, the 30 vaccine teams gave immunizations on 23 days. Vaccine rates were higher in those aged cold chain was maintained and documented. 66 individuals reported of adverse events out of all vaccinees, where fever (21%), malaise (19%) and local redness (19%) were the major symptoms; no life-threatening event occurred. Three needle-sharp events were reported. The mass immunization proved feasible and safe, and vaccine coverage was high. Emphasis should be placed on: injection safety measures, community involvement and incorporation of mop-up strategies into any vaccination campaign. School-based and all-age Vi mass immunizations programs are potentially important public health strategies for prevention of typhoid fever in high-risk populations in southern China.

    Melioidosis, an infectious disease caused by the Gram-negative bacterium Burkholderia pseudomallei, is now recognized as an important public health problem in Southeast Asia and tropical northern Australia. Although B. pseudomallei has been detected in various water and soil samples in southeast China, the enviromental distribution of B. pseudomallei in China is unclear. In the winter months of 2007, 154 and 130 soil and water samples, respectively, were collected from several locations in Guangxi, China. The samples were screened for B. pseudomallei by bacterial culture and identification and confirmed by PCR for species-specific 16S rDNA and flagellin genes. B. pseudomallei was detected in 8.4% of the soil samples but in none of the water samples. All positive samples were confined to a single low-lying region from rice paddy fields. Counts of B. pseudomallei ranged from 23 to 521 c.f.u./g soil. This is the first geographical distribution survey of B. pseudomallei in soil in Guangxi, China, and the data are of importance for further evaluating the impact of this pathogen on melioidosis in this region.

    Nonlinear complexity is a characteristic of hydrologic processes. Using fewer model parameters is recommended to reduce error. This study investigates, and compares, the ability of gene expression programming (GEP) and artificial neural network (ANN) techniques in modeling ET0 by using fewer meteorological parameters in the karst area of northwest Guangxi province, China. Over a 5-year period (2008-2012), meteorological data consisting of maximum and minimum air temperature, relative humidity, wind speed, and sunshine duration were collected from four weather stations: BaiSe, DuAn, HeChi, and RongAn. The ET0 calculated by the FAO-56 PM equation was used as a reference to evaluate results for GEP, ANN, and Hargreaves models. The coefficient of determination ( R 2) and the root mean square error (RMSE) were used as statistical indicators. Evaluations revealed that GEP, and ANN, can be used to successfully model ET0. In most cases, when using the same input variables, ANN models were superior to GEP. We then established ET0 equations with fewer parameters under various conditions. GEP can produce simple explicit mathematical formulations which are easier to use than the ANN models.

    Based on a partial postcranial skeleton collected from the Lower Cretaceous Napai Formation of Guangxi, China, we erect a new sauropod taxon, Fusuisaurus zhaoi gen. et sp. nov. The holotype specimen consists of the left ilium, left pubis, anterior caudals, most of the dorsal ribs and distal end of the left femur. Fusuisaurus zhaoi is diagnosed by a unique combination of character states among the known sauropods. It displays several synapomorphies of Titanosauriformes but lacks many derived features seen in other titanosauriforms, suggesting that the new taxon represents the basalmost known titanosauriform and providing new evidence that Titanosauriformes originated from Asia. A size comparison suggests that Fusuisaurus zhaoi is among the largest Early Cretaceous sauropods,providing an important addition to the Early Cretaceous Chinese sauropod diversity.

    Full Text Available The discrepancies across test sites and years, along with the interaction between cultivar and environment, make it difficult to accurately evaluate the differences of the sugarcane cultivars. Using a genotype main effect plus genotype-environment interaction (GGE Biplot software, the yield performance data of seven sugarcane cultivars in the 8th Chinese National Sugarcane Regional Tests were analyzed to identify cultivars recommended for commercial release. Fn38 produced a high and stable sugar yield. Gn02-70 had the lowest cane yield with high stability. Yz06-407 was a high cane yield cultivar with poor stability in sugar yield. Yz05-51 and Lc03-1137 had an unstable cane yield but relatively high sugar yield. Fn39 produced stable high sugar yield with low and unstable cane production. Significantly different sugar and cane yields were observed across seasons due to strong cultivar-environment interactions. Three areas, Guangxi Chongzuo, Guangxi Baise, and Guangxi Hechi, showed better representativeness of cane yield and sugar content than the other four areas. On the other hand, the areas Guangxi Chongzuo, Yunnan Lincang, and Yunnan Baoshan showed strong discrimination ability, while the areas Guangxi Hechi and Guangxi Liuzhou showed poor discrimination ability. This study provides a reference for cultivar evaluation and essential test locations identification for sugarcane breeding in China.

    Full Text Available The oriental pied hornbill (Anthracoceros albirostris albirostris is a State Protected Species and also an important seed dispersal agent in Tropical Asia. Recent studies show that the range of oriental piedhornbill in Guangxi has decreased significantly in the last decades. During the 1970s the species was widespread along the Sino-Vietnamese border but since the 2000s it has been confined to only three isolated areas. Although the population has declined substantially, Xidamingshan still supports the largest hornbill population known in Guangxi. In order to understand the current status of the species in Guangxi, China, we conducted a simultaneous population survey in Xidamingshan Nature Reserve in 2009. At least, fifty birds were recorded during survey and 124 plant species are identified as potential food source of the bird. Human disturbance and hunting are the main threats to the species in Guangxi. Further research and conservation of the species are urgently required.

    In Guangxi, a province of southern China, an important number of dogs and cats roam freely in rural settings, and the presence of these animals in proximity of people may represent a risk of parasitic zoonoses. The objective of the present study was to investigate the presence and identify gastrointestinal helminths in feral carnivores in Guangxi province. Therefore, post mortem examination was performed in 40 dogs and in 39 cats. The Gastrointestinal helminths were found in all the necropsied dogs and in 37 out of 39 cats. Fifteen species were identified including 7 trematodes, 3 cestodes and 5 nematodes. Most of them may be responsible for zoonotic infections. Major zoonotic gastrointestinal helminths, including liver and intestinal flukes, Toxocara spp., and Ancylostoma spp., are present in feral dogs and cats in Guangxi, and may represent a significant risk for public health.

    The orchid family is renowned for its enormous diversity of pollination mechanisms and unusually high occurrence of non-rewarding flowers compared to other plant families. We investigated the pollination biology of Cymbidium lancifolium during 2005 and 2006 in the Yachang Nature Reserve, Guangxi Province, SW China. Our observations showed that Apis cerana cerana (Hymenopterous, Apidae) was the only pollinator. The bee directly landed on the mid-lobe, then adjusted its direction and entered in...

    Microspherules are found in different fades at the Lower-Middle Devonian boundary, Guangxi, South China. There are more than 20 grains per kilogram rock sample. Composition and form of the microspherules are very similar to those of the microtektites from modern deposits of South Pacific Ocean and F-F boundary (Devonian). This may indicate that the microspherules from Guangxi are most likely the products of an extraterrestrial impact event that occurred at the end of Early Devonian Epoch. The event may be responsible for the biomass reduction and extinction of benthic organisms at the end of Early Devonian. The impact products (ejecta) can be used as a potential tool for stratigraphic correlation.

    Full Text Available Human rabies cases in the Guangxi province of China decreased from 839 in 1982 to 24 in 1995, but subsequently underwent a sharp increase, and has since maintained a high level.3,040 brain samples from normal dogs and cats were collected from 14 districts of Guangxi and assessed by RT-PCR. The brain samples showed an average rabies virus (RV positivity rate of 3.26%, but reached 4.71% for the period Apr 2002 to Dec 2003. A total of 30 isolates were obtained from normal dogs and 28 isolates from rabid animals by the mouse inoculation test (MIT. Six representative group I and II RV isolates showed an LD50 of 10-5.35/ml to 10-6.19/ml. The reactivity of monoclonal antibodies (MAbs to group I and II RV isolates from the Guangxi major epidemic showed that eight anti-G MAbs showed strong reactivity with isolates of group I and II with titers of ≥10,000; however, the MAbs 9-6, 13-3 and 12-14 showed lower reactivity. Phylogenetic analysis based on the G gene demonstrated that the Guangxi RV isolates have similar topologies with strong bootstrap values and are closely bonded. Alignment of deduced amino acids revealed that the mature G protein has four substitutions A96S, L132F, N436S, and A447I specific to group I, and 13 substitutions T90M, Y168C, S204G, T249I, P253S, S289T, V332I, Q382H, V427I, L474P, R463K Q486H, and T487N specific to group II, coinciding with the phylogenetic analysis of the isolates.Re-emergence of human rabies has mainly occurred in rural areas of Guangxi since 1996. The human rabies incidence rate increased is related with RV positive rate of normal dogs. The Guangxi isolates tested showed a similar pathogenicity and antigenicity. The results of phylogenetic analysis coincide with that of alignment of deduced amino acids.

    The increasing riverine pollutants have resulted in nutrient enrichment and deterioration of water quality in the coastal water of Guangxi Province, China. However, the quantitative relationship between nutrient loads and water quality responses, which is crucial for developing eutrophication control strategies, is not well studied. In this study, the riverine fluxes of nutrients were quan-tified and integrated with nutrient cycling and phytoplankton dynamics by using box models for Guangxi coastal bays. The model concepts and biogeochemical equations were the same; while most model parameters were specific for each bay. The parameters were calibrated with seasonal observations during 2006-2007, and validated with yearly averaged measurements in 2009. The gen-eral features of nutrient and phytoplankton dynamics were reproduced, and the models were proved feasible under a wide range of bay conditions. Dissolved inorganic nitrogen was depleted during the spring algal bloom in Zhenzhu Bay and Fangcheng Bay with relatively less nutrient inputs. Phosphorus concentration was high in spring, which decreased then due to continuous phytoplankton consumption. Chlorophyll-a concentration reached its annual maximum in summer, but was the minimum in winter. Eutrophication was characterized by both an increase in nutrient concentrations and phytoplankton biomass in Lianzhou Bay. Either about 80%re-duction of nitrogen or 70%reduction of phosphorus was required to control the algal bloom in Lianzhou Bay. Defects of the models were discussed and suggestions to the environmental protection of Guangxi coastal bays were proposed.

    Sequencing of the complete hepatitis B virus (HBV) genomes from Vietnam, China and Laos led to the identification of a complex recombinant, referred to initially as an aberrant genotype and later proposed to be a new genotype, I. However, epidemiological data regarding this new genotype are lacking. A cross-sectional study was carried out to investigate the epidemiology of HBV candidate genotype I in Guangxi, China using stratified, random cluster sampling. Four thousand five hundred thirteen subjects were recruited from five counties within Guangxi. Three genotypes, B, C, and I, were identified with a prevalence of 32.6% (114/350), 64% (224/350), and 3.4% (12/350), respectively. All the genotype I isolates belong to candidate subgenotype I1 and were found in Bing Yang (15.3%, 9/59) and Na Po (5.0%, 3/60) counties only. The prevalence of this subgenotype is significantly higher in males (5.1%, 10/195) than in females (1.3%, 2/155; X(2)  = 3.959, P HBV serological markers. Phylogeographic analysis revealed that genotype I1 likely arose in Long An county, then spread later to Bing Yang, Na Po counties and elsewhere in southeast Asia. In conclusion, the distribution of candidate genotype I within Guangxi is not even and it is highly endemic in some counties. Its prevalence is associated with gender and ethnicity. Subgenotype I1 likely originated in Long An county.

  17. Epidemiological surveillance of low pathogenic avian influenza virus (LPAIV from poultry in Guangxi Province, Southern China.

    Yi Peng

    Full Text Available Low pathogenic avian influenza virus (LPAIV usually causes mild disease or asymptomatic infection in poultry. However, some LPAIV strains can be transmitted to humans and cause severe infection. Genetic rearrangement and recombination of even low pathogenic influenza may generate a novel virus with increased virulence, posing a substantial risk to public health. Southern China is regarded as the world "influenza epicenter", due to a rash of outbreaks of influenza in recent years. In this study, we conducted an epidemiological survey of LPAIV at different live bird markets (LBMs in Guangxi province, Southern China. From January 2009 to December 2011, we collected 3,121 cotton swab samples of larynx, trachea and cloaca from the poultry at LBMs in Guangxi. Virus isolation, hemagglutination inhibition (HI assay, and RT-PCR were used to detect and subtype LPAIV in the collected samples. Of the 3,121 samples, 336 samples (10.8% were LPAIV positive, including 54 (1.7% in chicken and 282 (9.1% in duck. The identified LPAIV were H3N1, H3N2, H6N1, H6N2, H6N5, H6N6, H6N8, and H9N2, which are combinations of seven HA subtypes (H1, H3, H4, H6, H9, H10 and H11 and five NA subtypes (N1, N2, N5, N6 and N8. The H3 and H9 subtypes are predominant in the identified LPAIVs. Among the 336 cases, 29 types of mixed infection of different HA subtypes were identified in 87 of the cases (25.9%. The mixed infections may provide opportunities for genetic recombination. Our results suggest that the LPAIV epidemiology in poultry in the Guangxi province in southern China is complicated and highlights the need for further epidemiological and genetic studies of LPAIV in this area.

  18. Late Changhsingian radiolarian biostratigraphy from Guangxi,South China and its correlation to conodonts

    2008-01-01

    A well-preserved, abundant radiolarian fauna was obtained from three sections: the Dongpan, Liuqiao, and Paibi sections, in southern Guangxi, South China. Sixteen species belonging to Albaillella and Neoalbaillella, including seven undetermined species, are recognized. On the basis of stratigraphic distribution of these species, two radiolarian zones, the Albaillella triangularis Zone and the Albaillella yaoi Zone, are established. The correlation between radiolarian zones and conodont zones is suggested based on the discovery of coexisting conodonts. Albaillella triangularis and Albaillella yaoi zones correspond to Neogondolella postwangi and Neogondolella yini zones respectively.

    Background: Little research has been conducted on the prevalence of diabetes mellitus in underdeveloped areas in China, especially stratified into obesity and non-obese diabetes. The aim of the present study was to investigate the prevalence and associated factors of non-obese diabetes in an underdeveloped area in South China, Guangxi. Methods: Data derived from the Chinese Health and Nutrition Survey 2010–2012 involved a sample of 3874 adults from Guangxi. Questionnaires and oral glucose-tolerance tests were conducted, and fasting and 2-h glucose levels and serum lipids were measured. Logistic regression analysis was performed to assess associated factors for non-obese diabetes. Results: 68.2% and 62.2% of instances of newly detected diabetes were those of non-obese diabetes based on BMI (NODB) and based on WC (NODW), respectively. The male sex, an age older than 50 years, lower education, hypertension, and hypertriglyceridemia were significantly associated with a higher risk of both NODB and NODW, while some associated factors for NODB were found different from those associated with NODW, and an interaction effect was found to increase the risk of NODW. Conclusions: Our study indicated that non-obese diabetes was highly prevalent in an underdeveloped area of South China. Non-obese diabetes should be considered for increased public attention in these areas. PMID:27706056

  1. Characteristics and Advantages of Regional Grain Production in Guangxi Zhuang Autonomous Region of China

    Institute of Scientific and Technical Information of China (English)

    2010-01-01

    According to the latest Land Use Planning of Guangxi Zhuang Autonomous Region, Guangxi is divided into five regions, which are eastern Guangxi, western Guangxi, southern Guangxi, northern Guangxi, and central Guangxi. Regional variation characteristics of grain production are introduced from two aspects of the decline of grain sowing area and the increase of grain output. According to the data in Guangxi Statistical Yearbook, comparative advantages of regional grain production in Guangxi Zhuang Autonomous Region are analyzed by the method of Comprehensive Comparative Dominance Index. Result shows that eastern Guangxi and northern Guangxi have the maximum comprehensive dominance indices with the minimum increasing amount of dominance indices. Their advantages in grain production are gradually diminished; and the grain production center is moving to central Guangxi and southern Guangxi. In order to solve the problems in grain production, Guangxi should make full use of the comparative advantage in agricultural production, carry out structural adjustment of agricultural production, and try to realize the rational distribution and specialization of agricultural production.

    To demonstrate the performance of Hb Bart's Disease prevention in Guangxi Zhuang Autonomous Region, China. A prenatal control program for Hb Bart's disease was conducted from January 2006 to December 2012. A total of 17,555 pregnant women were screened for α-thalassemia in our prenatal screening program. Pregnancy at-risk for Hb Bart's disease was offered the choice of direct invasive testing or the non-invasive approach with serial ultrasonography. A total of 1425 at-risk couples attended the prenatal diagnosis. Three hundred ninety couples were screened at our own hospital, and the remaining 1035 couples were referred from other hospitals. Two hundred and three pregnant women chose non-invasive approach, and 1122 chose invasive testing. A total of 365 fetuses were diagnosed with Hb Bart's disease. All cases were finally confirmed by fetal DNA analysis. Eighty-two cases (22.4%) were diagnosed by chorionic villous sampling and 194 (53.2%) by amniocentesis samples. The other 89 (24.4%) cases were performed by cordocentesis. All of the affected pregnancies were terminated. Implementation of a prevention and control program accompanying with a referral system for prenatal diagnosis is technically feasible in Guangxi Zhuang Autonomous Region, China.

    Chengjing Nie

    Full Text Available BACKGROUND: In the past decade, bacillary dysentery was still a big public health problem in China, especially in Guangxi Province, where thousands of severe diarrhea cases occur every year. METHODS: Reported bacillary dysentery cases in Guangxi Province were obtained from local Centers for Diseases Prevention and Control. The 14 socio-economic indexes were selected as potential explanatory variables for the study. The spatial correlation analysis was used to explore the associations between the selected factors and bacillary dysentery incidence at county level, which was based on the software of ArcGIS10.2 and GeoDA 0.9.5i. RESULTS: The proportion of primary industry, the proportion of younger than 5-year-old children in total population, the number of hospitals per thousand persons and the rates of bacillary dysentery incidence show statistically significant positive correlation. But the proportion of secondary industry, per capital GDP, per capital government revenue, rural population proportion, popularization rate of tap water in rural area, access rate to the sanitation toilets in rural, number of beds in hospitals per thousand persons, medical and technical personnel per thousand persons and the rate of bacillary dysentery incidence show statistically significant negative correlation. The socio-economic factors can be divided into four aspects, including economic development, health development, medical development and human own condition. The four aspects were not isolated from each other, but interacted with each other.

    With a subtropical climate, Guangxi has a typical karst landscape. Land degradation has become a serious environmental issue due to its high vulnerability caused by the joint effect of natural settings in geology, topography, rainfall, and vegetative cover, as well as human activities such as deforestation. Its eco-environment has deteriorated over recent years while cultivated land is disappearing quickly. This, in turn, has exacerbated the poverty level in rural areas. In this study we monitored the spatial distribution of land degradation and its temporal evolution using Landsat TM/ETM images of the late 1980s, mid-1990s and late 2000 (for simplicity, we identified them as 1985, 1995 and 2000). We also explored the causes of its initiation and expansion. Through constructing regression models using all the relevant variables and considering the lagged effects as well as fixed effects, we quantified the exact role of different factors in causing land degradation in the study area with new findings. Based on these results we further analyzed the hazard of land degradation and proposed a few practical rehabilitation measures, including forestation, infrastructure projects, and ecological projects. The findings in this study are invaluable in preserving, restoring, and reconstructing the degraded environment in Guangxi and other karst areas in Southwest China while alleviating poverty in rural areas.

    With a subtropical climate, Guangxi Zhuaug Autonomous Region has a typical karst landscape. Rocky desertification has become a serious environmental issue due to its high vulnerability caused by the joint effect of natural settings and human activities, because of which its eco- environment has been deteriorated in recent years, and farmland has been disappearing sharply at the same time. This, in turn, has exacerbated the poverty level in the rural areas of the region. In this study, we monitored the spatial distribution of rocky land desertification and its temporal evolution using Landsat TM/ETM images of 1985, 1995, 2000 and 2005. We also analyzed the driving forces of the desertification and its expansion. Through constructing regression models by using all the relevant variables and considering the lagged effects as well as fixed effects, we quantified the exact role of different factors causing rocky land desertification in the study area with some new findings. The newfindings in this study are greatly helpful for preserving, restoring and reconstructing the degraded mountain environment in Guangxi and other karst areas in Southwest China, and also for alleviating poverty in the rural areas in the future.

    Primulina cardaminifolia Yan Liu & W.B. Xu (Gesneriaceae), a distinct new species with imparipinnate leaves, is described and illustrated from a limestone valley in Guangxi Zhuangzu Autonomous Region, China. To assure its generic placement and phylogenetic affinity, phylogenetic analyses were performed using DNA sequences of nuclear ITS and chloroplast trnL-F intron spacer region. Additionally, somatic chromosome number was counted and pollen stainability was tested. Phylogenetic analyses support its placement in Primulina; however, two phylogenetically distinct ITS sequence types were detected, suggesting a probable hybrid origin. Its pollen stainability is 100% and its chromosome number, 2n = 36, is congruent with all known counts of diploid species of the genus. All available data support the recognition of the new species Primulina cardaminifolia and suggest that it could have derived from homoploid hybrid speciation. Color plates, line drawings and a distribution map are provided to aid in identification.

    Full Text Available This study compares and evaluates the prediction of hepatitis in Guangxi Province, China by using back propagation neural networks based genetic algorithm (BPNN-GA, generalized regression neural networks (GRNN, and wavelet neural networks (WNN. In order to compare the results of forecasting, the data obtained from 2004 to 2013 and 2014 were used as modeling and forecasting samples, respectively. The results show that when the small data set of hepatitis has seasonal fluctuation, the prediction result by BPNN-GA will be better than the two other methods. The WNN method is suitable for predicting the large data set of hepatitis that has seasonal fluctuation and the same for the GRNN method when the data increases steadily.

    2017-01-01

    Full Text Available A calcisponge fauna occurs in uppermost Permian Conodont Clarkina meishanensis yini zone of the sequence exposed in the vicinity of Laibin, Guangxi Zhuang Autonomous Region, southern China. The fauna is dominated by one thalamid species, Amblysiphonella vesiculosa de Koninck, 1863, and one new sclerosponge genus and species, Radiofibrosclera laibinensis gen. et sp. nov. They are associated with a few other accessory species, including the thalamid sponges Amblysiphonella laibinensis Deng, 1981, Colospongia sp., Polycystocoelia sp., and the inozoan sponge Acoelia discontinua sp. nov. Though the individuals are abundant, the species diversity is very low. Without common calcisponge components of Changhsingian reefal faunas, the assemblage is interpreted as not a reefal fauna. The water depth at which they dwelled was less than 105 m, and more probably less than 40 m. Its occurrence indicates a significant sea-level drop at the end of Late Permian Changhsingian Age.

    2008-12-01

    Full Text Available BACKGROUND: Although confinement in drug detoxification ("detox" and re-education through labor (RTL centers is the most common form of treatment for drug dependence in China, little has been published about the experience of drug users in such settings. We conducted an assessment of the impact of detention on drug users' access to HIV prevention and treatment services and consequent threats to fundamental human rights protections. METHODS AND FINDINGS: Chinese government HIV and anti-narcotics legislation and policy documents were reviewed, and in-depth and key informant interviews were conducted with 19 injection drug users (IDUs and 20 government and nongovernmental organization officials in Nanning and Baise, Guangxi Province. Significant contradictions were found in HIV and antinarcotics policies, exemplified by the simultaneous expansion of community-based methadone maintenance therapy and the increasing number of drug users detained in detox and RTL center facilities. IDU study participants reported, on average, having used drugs for 14 y (range 8-23 y and had been confined to detox four times (range one to eight times and to RTL centers once (range zero to three times. IDUs expressed an intense fear of being recognized by the police and being detained, regardless of current drug use. Key informants and IDUs reported that routine HIV testing, without consent and without disclosure of the result, was the standard policy of detox and RTL center facilities, and that HIV-infected detainees were not routinely provided medical or drug dependency treatment, including antiretroviral therapy. IDUs received little or no information or means of HIV prevention, but reported numerous risk behaviors for HIV transmission while detained. CONCLUSIONS: Legal and policy review, and interviews with recently detained IDUs and key informants in Guangxi Province, China, found evidence of anti-narcotics policies and practices that appear to violate human rights

    2008-01-01

    This paper describes for the first time the cornute stylophorans (Echinodermata) in China. The new material came from the Guole Formation of the Furongian (Late Cambrian) in the Guole area of Jingxi,Guangxi Province, South China. These new cornute specimens are preserved in situ and found along with well-preserved trilobites and brachiopods. One new species, Phyllocystis jingxiensis sp. nov., is proposed to accommodate these unusual materials. The new species is defined by the small,heart-shaped theca with the frame composed of ten narrow, smooth and thick marginal plates, three adoral plates and distinctive zygal and aulacophore. Both supracentrals and infracentrals are polygonal-outlined. The marginal plate M/ on the inferior face extends posteriorly to form zygal that possesses a broadened proximal end and the proximal portion joining with the conjunction between M4 and M5 on the inferior face. Aulacophore comprises ten segments at its proximal part and is conical at the middle part (named stylocone). Its distal portion is rather long and bears conspicuous ambulacrum grooves. Tectals are horizontally arranged on superior face and obliquely arranged on inferior face.Both cothurnopore and anal pyramid are vaguely seen on the right anterior corner and the extremity of theca's superior face.

    Most bauxite in China is located upon the karst surface, yet the relation between karstification process and bauxite formation is barely known. Here we discuss how the relation affects the karst and bauxite evolution through analyzing distributions of orebody parameters from 9,007 exploration wells (434 orebodies) in western Guangxi, South China block. In high-elevation karst terrain dominated by peaks, orebodies have greater average thickness, lower Al2O3 and higher Fe2O3(T) than those in low-elevation region dominated by depressions. Principal component and multifractal analyses show that the Al2O3, Fe2O3(T) and LOI and the orebody thickness, determined by depression geometry, have more even distributions in high-elevation terrain. This explains that the interaction between the oxidized, alkaline water in karst surface and the ferrous clay minerals that released H(+) during bauxite secondary weathering was more intensive in high-elevation terrain than in low-elevation one. The interaction with self-organized nature is considered responsible for the even development of karstic depressions and bauxite orebody thicknesses in high-elevation terrain. In comparison, SiO2 distribution is more even in low-elevation terrain, where connected depressions near the phreatic zone facilitated SiO2 mobilization and even distribution.

    Healthcare financing should be equitable. Fairness in financial contribution and protection against financial risk is based on the notion that every household should pay a fair share. Health policy makers have long been concerned with protecting people from the possibility that ill health will lead to catastrophic financial payments and subsequent impoverishment. A number of studies on health care financing equity have been conducted in some provinces of China, but in Guangxi, we found such observation is not enough. What is the situation in Guagnxi? A research on rural areas of Guangxi can add knowledge in this field and help improve the equity and efficiency of health financing, particularly in low-income citizens in rural countries, is a major concern in China's medical sector reform. Socio-economic characteristics and healthcare payment data were obtained from two rounds of household surveys conducted in 2009 (4634 respondents) and 2013 (3951 respondents). The contributions of funding sources were determined and a progressivity analysis of government healthcare subsidies was performed. Household consumption expenditure and total healthcare payments were calculated and incidence and intensity of catastrophic health payments were measured. Summary indices (concentration index, Kakwani index and Gini coefficient) were obtained for the sources of healthcare financing: indirect taxes, out of pocket payments, and social insurance contributions. The overall health-care financing system was regressive. In 2013, the Kakwani index was 0.0013, the vertical effect of all the three funding sources was 0.0001, and some values exceeded 100%, indicating that vertical inequity had a large influence on causing total health financing inequity. The headcount of catastrophic health payment declined sharply between 2009 and 2013, using total expenditure (from 7.3% to 1.2%) or non-food expenditure (from 26.1% to 7.5%) as the indicator of household capacity to pay.

    Based on detailed measurement in the field and a comPrehensive analysis of carbonate microfacies, the Pennsylvanian reefal microfacies characteristic and sedimentary environment from Longjiangdong,Guangxi, China are analyzed. The twelve carbonate microfacies have been recognized including micritic/microsParitic limestone,Peloidal/aggregate-grain grainstone,bioclastic wackestone/Packstone,laminated mudstone,bounds-tone,bioclastic wackestone/Packstone with single shell,coral framestone/bafflestone,bioclastic Packstones/grainstones with abundant benthic foraminifera or crinoids,wackestone/mudstone with calcisPheres,bioclastic Packstone/grainstone,unname reef-building organism framestone and brachioPod grainstone. In addition,four facies have been identified including oPen Platform facies,restricted Platform facies,coral reefal facies and shoal facies. According to analysis of microfacies combination and facies evolution,three stages and three reef units during the reef formation Process have been noted. The evolution of each stage indicates a rePeating fluctu-ation of the sea-level,but the water energy is still relatively low overall,which rePresents frequent changes of Paleoclimate in the early Late Carboniferous.

    To reveal the relationship between species diversity and biomass in a eucalyptus (Eucalyptus urophylla × E. grandis) plantation located in the Dongmen State Forestry Farm of Guangxi, south China, 18 sample plots were established and the total biomass, arbor layer biomass and undergrowth biomass of communities were subsequently harvested. The results were as follows: 1) Species richness in eucalypt plantation had remarkable positive correlation with biomass of arbor layer, under growth and community (a = 0.001), its correlation coefficients were 0.6935, 0.7028 and 0.7106 respectively. 2) Leaf area index (LAI) had remarkable positive correlation with species richness and undergrowth biomass (a = 0.001). Its correlation coefficients were 0.7310 and 0.6856, respectively. 3) Arbor layer biomass had remarkable correlation with soil organic matter and hydrolysable N, its correlation coefficients was 0.6416 and 0.6203 respectively. Species richness had remarkable correlation with soil organic matter and correlation coefficient was 0.6359. Among them, the correlation was significant at the 0.1 level. Undergrowth biomass had little correlation with nine soil nutrients and correlation coefficients were under 0.4. To sum up, species diversity was advantageous to the promotion of the biomass of the eucalyptus plantation, and the variation of LAI and soil nutrient in small-scales could result in the difference of species diversity and biomass in different sample plots.

  19. Organic geochemical characterization and depositional paleoenvironments of the Devonian strata in Guizhong region,Guangxi,China

    2009-01-01

    Devonian strata in the Guizhong region,Guangxi,China consist mainly of marine deposition carbonates(limestones and dolomites) as well as restricted clastic rocks. The strata thickness is measured as 2041m and classified into 14 formations. An integrated field geological,petrographic,sedimentological,palaeobiological,and geochemical study of these strata reveals that the depositional paleoenvironments were carbonate tidal flat,restricted platform,open platform,shelf,platform margin slop,and algal herm. The total organic carbon(TOC) of sedimentary organic matter ranges between 0.07% and 1.96% with average of 0.21%. The organic matter types are Type ? and Type II1. The vitrinite reflectance(R0) of kerogen ranges between 0.99% and 2.03%,indicating the maturated and highly maturated stages. The analytical results of the representative samples collected from shelf and subtidal facies show that the differences of organic matter type and biological diagnostic compounds are related to the types of source rocks deposited in different paleoenvironments.

    A new species of the genusOdorrana is described from a completely dark karst cave of northeastern Guangxi, southern China. The new species,Odorranalipuensissp. nov., can be distinguished from its congeners by a combination of the following characters: medium size (SVL: 40.7–47.7 mm in males, 51.1–55.4 mm in females);tips of all but ifrst ifnger expanded with circummarginal grooves; smooth, grass-green dorsum with irregular brown mottling; pineal body invisible; throat to upper abdomen with gray mottling; dorsal surfaces of limbs with brown bands; dorsolateral fold absent; tiny spinules on lateral body, temporal region, and anterior and posterior edge of tympanum;white nuptial pad present on ifnger I; males lacking vocal sacs; females having creamy yellow eggs, without black poles. Uncorrected sequence divergences betweenO.lipuensissp. nov. and all homologous 16S rRNA sequences ofOdorrana available on GenBank is equal to or greater than 4.9%. Currently, the new species is only known from the type locality.

    Full Text Available Background. A newborn screening program (NSP for congenital hypothyroidism (CH was carried out in Guangxi in order to understand the incidence of CH and the factors interrelated to major types of CH in this region of China. Methods. During 2009 to 2013, data from 930 612 newborns attending NSP in Guangxi were collected. Patients were classified with either permanent CH (PCH or transient CH (TCH after 2 years of progressive study. Results. A total of 1210 patients were confirmed with CH with an incidence of 1/769, including 68 PCH and 126 TCH cases with incidences of 1/6673 and 1/3385, respectively. The frequency of thyroid stimulating hormone values greater than 5 mIU/L was 7.2%, which, based on WHO guidelines, suggests that the population was mildly iodine deficient. Conclusions. The incidence of CH was high in Guangxi. Approximately two thirds of CH patients were TCH, which may be due to a deficiency in iodine within the population.

    A life-cycle assessment (LCA) was carried out to compare the energy, environmental and economic impacts of converting cassava to fuel ethanol in Guangxi Province, China. The entire life cycle is a system that includes stages from cassava farming to ethanol fuel combustion. A computer-based model was developed to assess energy, environmental, and economic (EEE) life cycle implication of cassava-based ethanol fuel. The LCA results for fuel ethanol were compared to conventional gasoline (CG) as a base-line case. On the life-cycle bases, the use of cassava-based ethanol fuel in Guangxi may consume more energy but reduce greenhouse gas, VOC, and CO emissions. Life cycle cost results indicate that although fuel ethanol currently is not competitive compared to conventional gasoline, it has great potentials when there are subsidies and/or yields of cassava planting are improved. In terms of balancing the energy, environmental and economical, the introduction form of cassavabased ethanol fuel would be E10. The assessment results generated from this study provide an important reference for Guangxi policy makers to better understand the trade-offs among energy, environmental effects, and economics for the most effective using of regional energy resources.

    The current nitrogen fertilization for sugarcane production in Guangxi, the major sugarcane-producing area in China, is very high. We aim to reduce nitrogen fertilization and improve sugarcane production in Guangxi with the help of indigenous sugarcane-associated nitrogen-fixing bacteria. We initially obtained 196 fast-growing bacterial isolates associated with the main sugarcane cultivar ROC22 plants in fields using a nitrogen-deficient minimal medium and screened out 43 nitrogen-fixing isolates. Analysis of 16S rRNA gene sequences revealed that 42 of the 43 nitrogen-fixing isolates were affiliated with the genera Enterobacter and Klebsiella. Most of the nitrogen-fixing enterobacteria possessed two other plant growth-promoting activities of IAA production, siderophore production and phosphate solubilization. Two Enterobacter spp. strains of NN145S and NN143E isolated from rhizosphere soil and surface-sterilized roots, respectively, of the same ROC22 plant were used to inoculate micropropagated sugarcane plantlets. Both strains increased the biomass and nitrogen content of the sugarcane seedlings grown with nitrogen fertilization equivalent to 180 kg urea ha(-1), the recommended nitrogen fertilization for ROC22 cane crops at the seedling stage. (15)N isotope dilution assays demonstrated that biological nitrogen fixation contributed to plant growth promotion. These results suggested that indigenous nitrogen-fixing enterobacteria have the potential to fix N(2) associated with sugarcane plants grown in fields in Guangxi and to improve sugarcane production.

    Full Text Available Southern Guangxi Province is one of the important areas for the study of the Silurian/Devonian boundary (SDB in South China. Despite attempts to define the exact level of the SDB in the Yulin (Guangxi Province area using biostratigraphy, no consensus has been reached as the indicator fossils (e.g. graptolite Monograptus uniformis uniformis, conodont Icriodus woschmidti woschmidti and trilobite Warburgella rugulosa rugosa are not coexistent in South China. Since Mann et al. (2001: Dynamics of the Silurian/Devonian boundary sequence: sedimentary cycles vs. organic matter variation. Terra Nostra, 2001, 44–48 reported the first isotope curve based on organic carbon for the SDB at Klonk in the Czech Republic (GSSP, some comparable variation curves of δ13Corg across the SDB have been obtained at several locations including sections in Turkey and China. This distinct variation curve of the isotopic composition of organic carbon across the SDB provides a chemostratigraphic reference for a worldwide correlation of the SDB. In this study, organic geochemistry together with graptolite biostratigraphy is applied as a tool for identifying the SDB at the Changwantang Section in Yulin (Guangxi Province. The results suggest that the variations in some indexes of organic geochemistry can be correlated to the representative curve of the SDB in the Klonk and Esenyali sections. The exact level of the SDB in the Changwantang Section is positioned within the upper part of the Fangcheng Formation, which is consistent with the available palaeontological data from graptolites (e.g. Colonograptus colonus, Plectograptus sp., Monograptus uniformis, M. cf. M. praehercynicus and M. aequabilis.

    To gain more knowledge on the transformation process of dissolved inorganic carbon in a karst reservoir, in situ monitoring, sampling and lab experiments of water columns were carried out at various sampling sites along the flow line in Wulixia Reservoir, Guangxi, China during early July, 2013. Results showed that: (1) The hydrochemical characteristics of study areas were controlled by the carbonate equilibrium system and the hydrochemical type of all water samples was HCO3-Ca + Mg. (2) The DIC concentration decreased gradually (DIC(Average) : from 1.03 to 0.78 mmol x L(-1)) and the delta13C(DIC) increased gradually (delta13C(DIC(Average) : from -10.21per thousand to -6.62 per thousand) from the reservoir end area to dam area. Meanwhile, with the depth increase in water column, the DIC concentration increased gradually (DIC(Average) : from 0.86 to 1.05 mmol x L(-1)) and the delta13C(DIC) decreased gradually (delta13C(DIC(Average) : from -7.88 per thousand to -13.39 per thousand) from the surface to the bottom of the reservoir. Possible reasons for these research results were found as follows: (1) Dissolution-precipitation process of carbonate substance could be inhibited by other processes such as biogeochemical processes, which played little role in delta13C(DIC) variations. (2) Thermal stratification existed in the study areas which could influence the distribution of DIC and delta13C(DIC) by affecting the distribution of plankton and its orientation and strength of metabolism process, and the extent of organic matter decomposition, and so on.

    The hierarchically organized laminae, bundles, bundlesets and superbundlesets which correspond to a sub-Milankovitch, obliquity or precession, eccentricity and long eccentricity cyclothems, respectively, have been distinguished from the Upper Devonian Frasnian-Famennian (F-F) transitional carbonate successions deposited in the carbonate-basin and slope facies of Guangxi, South China. The durations of cyclothems are 8000-10000a, 16667a or 33333a, 100000a and 400000a, respectively. The ratio of eccentricity to precession, eccentricity to obliquity, and long eccentricity to eccentricity is 1:6,1:3 and 1 : 4 in the Devonian,respectively. Orbital cyclostratigraphical studies show that the durations of the conodont falsiovalis Zone, transitans Zone, punctata Zone, Lower hassi Zone, Upper hassi Zone, jamieae Zone,Lower rhenana Zone, Upper rhenana Zone,linguiformis Zone, Lower triangularis Zone, Middle triangularis Zone and Upper triangularis Zone are 0.4, 0.4, 0.4, 0.3, 0.4, 0.2, 0.8, 0.6, 0.8, 0.3, 0.3and 0.3 Ma from bottom to top, respectively, and the duration of the Frasnian is 4.3 Ma. The conodont is the normal marine organism of the latest mass extinction (the latest linguiformis Zone)and the first recovery (including the whole Lower triangularis and Middle triangularis Zone) in the F-F transition. The conodont mass extinction and recovery lasted 200000-100000a and 0.6 Ma,respectively. We consider that average durations of the fossil zones calculated by reported numerical ages divided by fossil zone numbers within a stage or series or system cannot discovery complications and non-uniformity of evolutionary organisms and environments.

    Trends in vegetation change and their relationships with terrain conditions are significant to understand and evaluate the efficiency of ecological engineering implemented in karst regions, Southwest China. This study aimed to identify vegetation change trends in Hechi, Guangxi, China using time-series of SPOT-VGT NDVI data (1999-2010) and DEM. Linear trend analysis was applied to examine NDVI change trends. The results indicated that most of NDVI values had increased during this time period. There were spatial variations in NDVI change trends, which could be partiallly explained by different karst terrain conditions. The areas of most obviously positive trends in NDVI change were found at the elevation of 500-1000m and the relief amplitude between 200 and 500 m. Negative trends in NDVI change were appeared on slopes of south (sunlit) and west (semi-sunlit) aspect and at the elevation of 200 - 500 m, where were mainly due to human activities.

    Objective To measure prevalence of syphilis among the STI clinic population in Guangxi, China, and to assess the socioeconomic and behavioural characteristics associated with the infection. Methods We undertook a cross‐sectional survey and syphilis and HIV serologic testing among 11 473 patients attending 14 community and hospital‐based dermatovenereal clinics across eight cities in Guangxi between December 2004 and February 2006. Results 1297 (11.9%) patients demonstrated positive toludine red unheated serum test and Treponema pallidum particle agglutination results with serologic testing. A total of 58% (752) of seropositive subjects presented with a genital ulcer, palmar/plantar rash or inguinal lymphadenopathy. Female sex (OR = 2.23, 95% confidence intervals (CI) = 1.69 to 3.00, p30 000 RMB yuan) were associated with serologically positive status. Syphilis infection was significantly more prevalent in city 2 (19.5%, OR = 3.07, 95% CI = 1.83 to 5.16, pinfected subjects engaged in commercial sex and increased rates of the infection was associated with multiple sexual partners (OR = 1.54, 95% CI = 1.16 to 2.06, p = 0.003). A total of 1.2% (133) of participants carried laboratory markers for HIV and 1.8% (23) of patients with syphilis were positive for HIV. Conclusions Syphilis infection has reached alarming rates in China's STI clinic population, suggesting a generalised spread of the disease through commercial sex and bridging populations. Syphilis control is deserving of China's highest priority. Universal screening for syphilis and HIV testing in STI clinics should be considered as measures for control. PMID:17591664

    Abundant normal alkanes,isoprenoid hydrocarbons,terpanes and steranes were detected in 23 samples taken from the carbonate platform to basin facies in the Devonian Frasnian-Famennian (F-F) transition of Guangxi,South China.They were mainly derived from the phytoplankton or bacteria and algae.Molecular stratigraphic parameters,abundant micron gypsums and pyrite framboids show that hypersaline and anoxia prevailed in the F-F transition,the highly stressed environments occurred near the F-F boundary.Orbital cyclostratigraphic studies indicate that the hypersaline and anoxia prevailed in the F-F transition spanned an interval at least from the Palmatolepis linguiformis conodont Zone to the Middle Palmatolepis triangularis conodont Zone and lasted about 1.2 Ma.The Devonian marine ecosystem underwent Early Devonian gradual optimization,Middle Devonian to the F-F transitional stepwise deterioration and late Famennian recovery.A positive feedback among higher surface ocean temperatures,hypersaline,water column anoxia, enhanced nutrient regeneration,phytoplankton productivity and eutrophication was probably substantial in the F-F transition in Guangxi,South China,even in other regions of the world,such as Holy Cross Mountains of Poland,Montagne Noire in southern France,Alberta in Canada.The point that should be emphasized is that the decisive and direct causes of the F-F transitional mass extinction would be the stepwise deterioration of the marine ecosystem since the Middle Devonian other than a bolide impact on the earth.The hypersaline and anoxia prevailed in the F-F transition favor the formation and preservation of hydrocarbon source rocks in South China.

    借助苔藓对广西河池锑冶炼区周边大气中的10种重金属( Sb、Pb、As、Cu、Cd、Mn、Fe、AI、Ba、Sr)的分布迁移规律进行了研究.结果表明:苔藓可有效反映重金属的沉降.苔藓中w(Sb)、w(Pb)、w(As)和w(Cd)的范围分别为41.0~5.77 ×103、1.05×102 ~ 1.39×104、25.0~1.07×103和8.00 ~ 263 mg/kg,分别是背景值的1.5~213.6、24.5 ~322.5、3.6~1 980.9和3.2~105.2倍.元素相关性的主成分分析表明,Sb、Pb、As、Cd和Cu为密切相关的一类元素,来源于原料矿石的冶炼排放;Mn、Fe和A1为第2类,主要来源于燃料煤的释放,此外,Mn还可能来源于城市气溶胶的输送和水泥厂的排放;Ba与Sr为第3类,来源与扬尘有关.随着采样点与冶炼厂烟囱距离的增加,w(Sb)、w(Pb)、w(As)、w(Cu)和w(Cd)呈非线性下降,可用方程y=ae-x拟合.w(Sb)与w(Pb)的衰减速率相似,而w(As)衰减要快于二者.%The distributions of Sb,Pb,As,Cu,Cd,Mn,Fe Al,Ba and Sr in the atmosphere around a smelter were investigated by using mosses as the indicator. Moss proved to be an effective indicator for the deposition of trace metals from the smelter. Contents of Sb,Pb and As in mosses were in the range of 41. 0-5. 77 x 103,1. 05 x 102-l. 39 x 104 ,25. 0-1. 07 x 103 and 8. 00-263 mg/kg,which are 1. 5-213. 6,24. 5-322. 5,3. 6-1980. 9 and 3. 2-105. 2 times higher,respectively,than the background values. Factor and correlation analysis show that the first group of elements,Sb,Pb,As,Cu and Cd,were significantly related to the smelter,and that these elements originated from ore smelting. The second group,Mn,Fe and Al,mainly originated from coal combustion in the smelter. Mn also originated from the transport of airborne urban pollutants and cement plants. The third group,Ba and Sr,probably originated from dust. The relationships between the contents of Sb,Pb,As,Cu,Cd and the distance from the sampling sites to the smelter could be best fitted by the model y = ae ". Sb and Pb contents show a highly similar attenuation trend,whereas As content decreased more rapidly than Sb or Pb content.

    Radiofrequency (RF) electromagnetic field (EMF) exposure from wireless telecommunication base station antennae can lead to debates, conflicts or litigations among the adjacent residents if inappropriately managed. This paper presents a measurement campaign for the GSM band EMF exposure in the vicinity of 827 base station sites (totally 6207 measurement points) in Guangxi, China. Measurement specifications are designed for risk communication with the residents who previously complained of over-exposure. The EMF power densities with the global positioning system coordinate at each measured point were recorded. Compliance with the International Commission on Non-Ionizing Radiation Protection guidelines and Chinese environmental EMF safety standards was studied. The results show that the GSM band EMF level near the base stations is very low. The measurement results and the EMF risk communication procedures positively influence public perception of the RF EMF exposure from the base stations and promote the exchange of EMF exposure-related knowledge.

    Full Text Available Early Triassic (Griesbachian to Spathian ostracod faunas are here first discovered and described form the Guangxi Province, South China. Thirty-seven species belonging to fourteen genera are recognized. Seven species are new: Bairdia fengshanensis n.sp., Bairdia wailiensis n.sp., Liuzhinia guangxiensis n.sp., Ptychobairdia luciaae n.sp., Ptychobairdia aldaae n.sp., Paracypris jinyaensis n.sp. and Paracypris gaetanii n.sp. The Griesbachian assemblage from the basal microbial limestone is well diversified and does not suggest any abnormal palaeoenvironmental conditions in terms of salinity, temperature or oxygen content. Particularly, the ostracods are typical of well oxygenated water and do not reflect any anoxia. Dienerian and Smithian ostracods are evidenced for the first time and the assemblages suggest less favourable palaeoenviromental conditions. Diversity and abundance of ostracod assemblages recovered from the Spathian on. The main taxonomic turnover among ostracod assemblages occurred seemingly between the Griesbachian and the Spathian.

    AIM: To investigate the corneal endothelial cell density and morphology and central corneal thickness in the Guangxi Maonan and Han adolescent students of China.METHODS: Noncontact specular microscope(Topcon SP3000 P, Tokyo, Japan) was performed in 133 adolescent students of Maonan nationality(M:F 54:79)and 105 adolescent students of Han nationality(M:F 50:55),5 to 20 y of age, who were randomly selected from 3schools in Huanjiang Maonan Autonomous County of Guangxi Zhuang Autonomous Region of China.Parameters studied included endothelial cell density,mean cell area, coefficient of variation in cell size,percentage hexagonality and central corneal thickness. RESULTS: Endothelial cell density, mean cell area,coefficient of variation in cell size, percentage hexagonality and central corneal thickness in the study population were(2969.50 ±253.93) cells/mm2,(339.23 ±29.44) μm2,(29.96 ±4.07) %,(64.58 ±9.41) % and(523.71 ±32.82) μm in Maonan and(2998.26 ±262.65) cells/mm2,(336.11±30.07) μm2,(29.89±5.03) %,(64.91±11.64) % and(524.39 ±33.15) μm in Han, respectively. No significant differences were observed in endothelial cell density,mean cell area, coefficient of variation in cell size,percentage hexagonality and central corneal thickness between Maonan and Han(P =0.615, 0.659, 0.528, 0.551,0.999). In Maonan and Han, we found age was negatively correlated with endothelial cell density and percentagehexagonality and positively correlated with mean cell area and coefficient of variation in cell size. Negative correlation was also found between central corneal thickness and age in Han, whereas no correlation was found in Maonan. CONCLUSION: There were no differences between Maonan and Han in corneal endothelial cell density and morphology and central corneal thickness. In these two nationalities, there were statistically significant decrease in endothelial cell density and percentage hexagonality with increasing age and statistically significant increase in

    Full Text Available Japanese encephalitis (JE is one of the most severe kinds of viral encephalitis and is prevalent in Asia and the Western Pacific. In China, JE was first reported in the 1940s and became the main cause of viral encephalitis, including in the Guangxi Zhuang Autonomous Region. In 1951, JE was included in the Chinese mandatory disease reporting system. In the pre-vaccine era of the 1960s and 1970s, the incidence of JE continued to rise without any vaccine supply. Since JE vaccines became available in the late 1970s (MBD and 1989 (LAV-SA-14-14-2, and as JE vaccine became freely available to patients beginning in 2008, the incidence of JE has declined significantly. Despite these gains, outbreaks continue to occur among children in rural and suburban areas. Strengthening vaccine delivery models and improving swine vaccine production are important in order to sustain continuous declines in the incidence of JE in Guangxi.

    Test environments and classification of regional ecological zones into mega environments are the two key components in regional testing of sugarcane cultivars. This study aims to provide the theoretical basis for test environment evaluation and ecological zone division for sugarcane cultivars. In the present study, sugarcane yield data from a three-year nationwide field trial involving 21 cultivars and 14 pilot test locations were analysed using both analysis of variance (ANOVA) and heritability adjusted-genotype main effect plus genotype-environment interaction (HA-GGE) biplot. The results showed that among the interactive factors, the GE interaction had the greatest impact, while the genotype and year interaction showed the lowest impact. Kaiyuan, Lincang and Baoshan of Yunnan, Zhangzhou and Fuzhou of Fujian, and Hechi, Liuzhou and Chongzuo of Guangxi, and Lingao of Hainan were ideal test environments with a demonstrated high efficiency in selecting new cultivars with a wide adaptability, whereas Baise of Guangxi was not. Based on HA-GGE biplot analysis, there are three ecological sugarcane production zones in China, the Southern China Inland Zone, the Southwestern Plateau Zone, and the Southern Coastal Zone. The HA-GGE biplot analysis here presents the ideal test environments and also identifies the mega-environment for sugarcane cultivars in China.

    Spartina alterniflora was introduced to Beihai, Guangxi (China), for ecological engineering purposes in 1979. However, the exceptional adaptability and reproductive ability of this species have led to its extensive dispersal into other habitats, where it has had a negative impact on native species and threatens the local mangrove and mudflat ecosystems. To obtain the distribution and spread of Spartina alterniflora, we collected HJ-1 CCD imagery from 2009 and 2011 and very high resolution (VHR) imagery from the unmanned aerial vehicle (UAV). The invasion area of Spartina alterniflora was 357.2 ha in 2011, which increased by 19.07% compared with the area in 2009. A field survey was conducted for verification and the total accuracy was 94.0%. The results of this paper show that VHR imagery can provide details on distribution, progress, and early detection of Spartina alterniflora invasion. OBIA, object based image analysis for remote sensing (RS) detection method, can enable control measures to be more effective, accurate, and less expensive than a field survey of the invasive population.

    The complete mitochondrial genome of Coelomactra antiquata (Guangxi, in China, GX) was determined. It is 16 801 bp in length and is the first representative from this province. The mitochondrial genome encodes 35 genes, including 12 PCGs, two ribosomal RNA, and 21 transfer RNA genes. Atp8 and trnSer(UCN) genes are missing, compared with the typical gene content of animal mitochondrial genomes. Three (cob, nad1, nad4, and nad6) of the 12 PCGs in the mitochondrial genome initiate with the ATA, while other PCGs start with ATG. Two PCGs (atp6 and nad4L) end with incomplete stop codons (T-), and the remaining ones have complete stop codons (TAA or TAG). The largest non-coding region of the C. antiquata (GX) contains one section of tandem repeats (5 × 99 bp). Among all PCGs and rRNAs, the nad5 gene contains the maximum polymorphic sites (430), followed by nad4 (261) and cox2 (240). Two ribosomal RNA genes (srRNA and lrRNA) and cox1 are most conservative. The proportions of polymorphic sites in six genes (nad4, nad2, nad6, nad5, cox2, and nad3) are more than 20% (ranging from 20.25% to 25.21%). These high variable genes can be used as molecular markers in the population genetic analysis of the species.

    Rocky desertification is a process of soil erosion leading to the bareness of bedrock, and is a kind of typical natural disaster in karst areas, which seriously constrains the developments of local society and economy. This paper studies the impact of human activities on the changes of rocky desertification. With the interpretation of remote sensing images of Fengshan County, GuangXi, China covering 1990, 1995 and 2005, this paper analyzes the relationship of the changes of social and economic index (including population density, agricultural population, rural per capital net income, and farmland) and the changes of rocky desertification in recent 15 years. The results indicate that: in recent 15 years, the average annual growth rate of rocky desertification, rate of change of population density, agricultural population, rural per capita net income, and farmland area are 8.7375 km2 /year, 0.7 person/km2.year, 1153 person/year, 85 Yuan/year, and -269.1 ha/year, respectively. The first three of social and economic indicators at different degrees of growth, show a positive correlation with rocky desertification change. However, farmland area, which has been diminishing, shows a negative correlation with rocky desertification. The influence of human activities for karst rocky desertification can be regarded as population growth - steep slope reclamation - the destruction of vegetation - erosion - rocky desertification - poverty.

    AIM: Glutathione S-transferase mu 1 (GSTM1) and theta 1(GSTT1) genes are involved in the metabolism of a wide range of carcinogens, but deletions of the genes are commonly found in the population. The present study was undertaken to evaluate the association between GSTM1 and GSTT1 gene polymorphisms and hepatocellular carcinoma (HCC) risk.METHODS: The genetic polymorphisms were studied at an aflatoxin highly contaminated region in Guangxi, China.Polymerase chain reaction (PCR) technique was used to detect the presence or absence of the GSTM1 and GSTT1 genes in blood samples. The case group was composed of 181 patients of HCC identified by the pathologists and the control group was composed of 360 adults without any tumor.RFSULTS: The frequencies of GSTM1 and GSTT1 null genotypes in the control were 47.8% and 42.7%, while those in the HCC group were 64.6% and 59.7%, respectively. The differences between HCC group and control group were very significant (P<0.01). GSTM1 and GSTT1 combined null genotypes in HCC group and control group were 38.2% and 18.5%respectively, and the difference was significant (P<0.05).CONCLUSION: The GSTM1 and GSTT1 null genotypes are associated with an increased risk of HCC in a special geographic environment. Combination of the two null genotypes in an individual is substantially increased twice the risk of HCC.

    Based upon a case study of Silver Beach coastal resort of Beihai,Guangxi Zhuang Autonomous Region,this article examines the rise and fall of Chinese coastal tourist resort development since the 1980s.It explores the causes for and responses to the decline of Chinese coastal resorts.The data were collected through in-depth interviews with twelve local key information providers,and secondary information sources such as government archives,survey reports,and resort plans.It was found that the rise and fall of Chinese coastal resorts in the last three decades is closely linked to the transitional reform from a central planned economy to a market economy.Three stages of coastal tourism development were identified in a sequence of rapid growth,decline and redevelopment.It was government financial funds and high local government involvement that promoted the rapid expansion of coastal resorts during the 1980s.However,coastal resort decline occurred when transitional reform was intensified and deflationary policy executed after 1992.Institutional failure is found to be the main reason of Chinese coastal resorts decline since the mid-1990s.The government-dominated pattern could not be sustained and should be restructured in forthcoming coastal tourism development in China.Revival strategies should emphasize enhancing market-oriented reform in the declining resorts on both supply and demand sides.

    Full Text Available Poverty is a social problem in developing countries, especially for the rural places experiencing rapid transition. This study characterizes the temporal changes of rural poverty under rural transition during 1991–2010 in Guangxi. In particular, poverty is measured by the Foster-Greer-Thorbecke method, and rural transition is described from three aspects including rural industrialization, regional urbanization, and agriculture commercialization. Relationships are quantified by multivariate linear regression. Results reveal that industry income proportion (IIP and secondary industry proportion (SIP are positive contributors to the poverty incidence, while urban-rural income gap (URIG is a negative contributor to the poverty incidence. Industrial total output of township and village enterprises (ITOE, IIP, and grain commercialization rate (GCR present positive correlation with the poverty depth. The URIG has a negative correlation with the poverty depth. Tertiary industry proportion (TIP and expenditure on fixed productive assets per capita (EFPA are positively correlated with the poverty severity, while URIG and power of agricultural machinery (PAM associate with poverty severity negatively. Redundancy analysis shows that individual influence of rural industrialization is higher than that of regional urbanization and agriculture commercialization. The joint influences of rural industrialization, regional urbanization, and agriculture commercialization are the strongest.

    Full Text Available This study describes HIV disease burden and patterns of drug use before and during incarceration among detainees in Re-education-Through-Labour-Camps (RTLCs in China. A cross-sectional survey of 576 men and 179 women from three RTLCs was conducted in Guangxi Province, China. Over three-quarters of study participants were detained due to drug-related offences. Over half of the women (n = 313, 54.3% and two-thirds of men (n = 119, 66.5% had been previously been incarcerated in a compulsory detoxification treatment centre (CDTC, and around one-third (men n = 159, 27.6%; women n = 50, 27.9% in a RTLC. Of those surveyed, 49 men (8.5% and one (0.6% woman reported ever using drugs while in a CDTC and/or RTLC. Previous incarceration in CDTCs and RTLCs were associated with HIV infection among both male (OR = 2.15 [1.11–4.15] and female (OR = 3.87 [1.86–9.04] detainees. Being married/cohabiting with a partner (OR = 0.53, [0.30–0.93] and being employed (OR = 0.46, [0.22–0.95] were associated with a reduced odds of HIV infection among male detainees. A significant proportion of RTLC detainees had a history of drug use and a limited number of inmates had used illegal substances whilst in custody. Repeat incarcerations in CDTCs/RTLCs were associated with higher risks of HIV infection.

    Sustainable use of natural resources is different from sustainable development. As the most important natu-ral resource, sustainable use of land resource is the essential guarantee of sustainable development. The nature of sustain-able use of land resource is to retain the quantity and productivity of land resource from generation to generation. The evalua-tion of sustainable use of land resource is an important method to ensure land-use to get onto the sustainable track. Further-more, building index system is the key of the evaluation. In view of tendency of the evaluation indexes chosen so widely,the evaluation indexes should include only three kinds in the researches on the evaluation of sustainable use of land re-source. The first is the stock and structure index of land resource, viz. Areas quantity structure of land resources. In Chi-na, it is especially paid attention to the per person index of land quantity and rate between cultivated land and farmland.The second is the productive index of land, which includes the productivity, potentiality, stability and renewal situationof land. The third is the sustained index of land environment. On the evaluation research of area level, we should layparticular emphasis on statistic indexes. With a case of Guangxi Zhuang Autonomous Region in China, the evaluationindex system of sustainable land-use in county area has been built in this thesis. Using the weighted average method tocalculate the means of sustainable land-use in each county, according to the land-using situation, all counties in the au-tonomous region have been divided into three types. (1) Sustainable Pattern contains 18 counties, which have higherland resource productivity, stronger sustained abilities of land environment. The economic benefits of land-using in thesecounties are obviously higher. These counties have gotten highly intensive farming, and they are all in the good circum-stance. (2) Basically Sustained Pattern contains 48 counties, which

    Full Text Available Background: In May 2012, an outbreak of viral hepatitis A was reported to the Guangxi Center for Disease Control and Prevention from a middle school in Liujiang County. An investigation was conducted to identify the cause and mode of transmission and to recommend control and prevention measures.Methods: A case was defined as any person from the middle school with onset of fatigue, anorexia, abdominal pain, diarrhoea or jaundice from 20 February to 20 May 2012. We compared attack rates (AR between boys and girls, assuming that only boys used well water and girls used pipeline water. We then selected 133 students from three classes in each of the three grades to compare AR by reported water source and drinking history.Results: There were 22 cases, an AR of 3.8% (21/553 for students and 1.5% for teachers (1/65. Those who used well water were 8.7 (95% confidence interval [CI] = 2.1–37.2 times more likely to be ill than those using pipeline water. The cohort study showed that students who reported using well water daily were 5.2 (95% CI = 0.7–41.8 times more likely to be ill than those that reported using the pipeline water daily. Eighteen cases were confirmed as hepatitis A.Conclusion: This hepatitis A outbreak was potentially caused by a contaminated school well. We recommended that the school discontinue using the well and that the students should drink boiled water. As there is a vaccine for hepatitis A, we recommended that several doses of the vaccine be stored for controlling outbreaks and for immunizing susceptible populations in future outbreaks.

    This paper aims to examine New Economics of Labor Migration (NELM) in the northwestern Guangxi,China and investigate the relationships among rural-urban migration, rural household income and local geographicalcontexts. Stratified sampling and typical case study were adopted and 236 questionnaires were collected from four vil-lages, Daxin, Lixin, Longhe and Yongchang. We analyzed the rural-urban migration rate, household income and localgeographical factors, focusing on the ratio of remittance income to total household income. Data descriptions and sta-tistical methods, such as Pearson Chi-square test, Contingency coefficient, Eta, Pearson correlation coefficient, t-test,multiple comparisons (LSD test, Tamhane T2, Dunnett T3 and Dunnet C test) were used. The results are as follows.Rural households'income is diversified in survey villages so the motivation of rural-urban migration in the study areacan be partly explained by NELM. The migration rate of households (the percentage of households with migrants insurvey households) in survey villages varies from 50% to 86%, while the proportion of remittance income to house-hold income is in the range of 30% to 80%. In the village of Yongchang, with the least average arable land area perhousehold, the remittance income plays a vital role in household income (80%). And the statistical findings show thatthe proportion is significantly and negatively correlated with arable land area per household. The conclusion is that di-rect effect of migration, i.e., the contribution of remittance to household income, is negatively correlated with the con-tribution of resources to local income.

    Full Text Available Background: Ethnic health inequalities for males and females among the elderly have not yet been verified in multicultural societies in developing countries. The aim of this study was to assess the extent of disparities in health expectancy among the elderly from different ethnic groups using quality-adjusted life expectancy. Design: A cross-sectional community-based survey was conducted. A total of 6,511 rural elderly individuals aged ≥60 years were selected from eight different ethnic groups in the Guangxi Zhuang Autonomous Region of China and assessed for health-related quality of life (HRQoL. The HRQoL utility value was combined with life expectancy at age 60 years (LE60 data by using Sullivan's method to estimate quality-adjusted life expectancy at age 60 years (QALE60 and loss in quality-adjusted life years (QALYs for each group. Results: Overall, LE60 and QALE60 for all ethnic groups were 20.9 and 18.0 years in men, respectively, and 24.2 and 20.3 years in women. The maximum gap in QALE60 between ethnic groups was 3.3 years in males and 4.6 years in females. The average loss in QALY was 2.9 years for men and 3.8 years for women. The correlation coefficient between LE60 and QALY lost was −0.53 in males and 0.12 in females. Conclusion: Women live longer than men, but they suffer more; men have a shorter life expectancy, but those who live longer are healthier. Attempts should be made to reduce suffering in the female elderly and improve longevity for men. Certain ethnic groups had low levels of QALE, needing special attention to improve their lifestyle and access to health care.

    After a big karst sinkhole happened in Jili Village of Guangxi, China, the local government was eager to quantitatively analyze and map susceptible areas of the potential second-time karst sinkholes in order to make timely decisions whether the residents living in the first-time sinkhole areas should move. For this reason, karst sinkholes susceptibility geospatial analysis is investigated using multivariate spatial data, logistic regression model (LRM) and Geographical Information System (GIS). Ten major karst sinkholes related factors, including (1) formation lithology, (2) soil structure, (3) profile curvature, (4) groundwater depth, (5) fluctuation of groundwater level, (6) percolation rate of soil, (7) degree of karst development, (8) distance from fault, (9) distance from the traffic route, and (10) overburden thickness were selected, and then each of factors was classified and quantitated with the three or four levels. The LRM was applied to evaluate which factor makes significant contributions to sinkhole. The results demonstrated that formation lithology, soil structure, profile curvature, groundwater depth, ground water level, percolation rate of soil, and degree of karst development, the distance from fault, and overburden thickness are positive, while one factor, the distance from traffic routes is negative, which is deleted from LRM model. The susceptibility of the potential sinkholes in the study area is estimated and mapped using the solved impact factors. The susceptible degrees of the study area are classified into five levels, very high, high, moderate, low, and ignore susceptibility. It has been found that that both very high and high susceptibility areas are along Datou Hill and the foothills of the study area. This finding is verified by field observations. With the investigations conducted in this paper, it can be concluded that the susceptibility maps produced in this paper are reliable and accurate, and useful as a reference for local

    In this investigation we analyzed the spatiotemporal variation of ecosystem service values (ESVs) and its correlation with numerous environmental factors (EFs) for the karst region of Northwest Guangxi, China, from 1985 to 2005 using remote sensing, geographic information systems (GIS) and statistical techniques. The results indicate that historically ESVs for this karst region decreased from 1985 (109.652 billion Yuan) to 1990 (88.789 billion Yuan) and then increased at the turn of the twenty-first century. However, the ESVs in both 2000 (103.384 billion Yuan) and 2005 (106.257 billion Yuan) never achieved the level recorded in 1985. The total of nutrient cycling, organic production and gas regulation combined were 72.69, 64.57, 70.18 and 72.10% of ESVs in 1985, 1990, 2000 and 2005, respectively. In contrast, the ESVs of water conservation, soil reservation, recreation and culture were determined to be relatively low contributing only 17.44, 23.82, 19.26 and 24.76% of total ESVs, respectively, during these four years. With regards to the spatial distribution of ESVs, larger values were recorded in the west and smaller ones recorded in the east. The most significant factors that were deemed to influence ESVs are annual rainfall, per capita cropland, slope and vegetation coverage. Annual rainfall and slope exert a negative force, whereas per capita cropland and vegetation coverage exert a positive force on ESVs. The results of the study would suggest that ecosystem conditions of this important karst region have been improved as the result of the implementation of rocky desertification control policies.

    Research shows potential effects of floods on intestinal infections. Baise, a city in Guangxi Province (China) had experienced several floods between 2004 and 2012 due to heavy and constant precipitation. This study aimed to examine the relationship between floods and the incidence of bacillary dysentery in Baise. A mixed generalized additive model and Spearman correlation were applied to analyze the relationship between monthly incidence of bacillary dysentery and 14 flood events with two severity levels. Data collected from 2004 to 2010 were utilized to estimate the parameters, whereas data from 2011 to 2012 were used to validate the model. There were in total 9255 cases of bacillary dysentery included in our analyses. According to the mixed generalized additive model, the relative risks (RR) of moderate and severe floods on the incidence of bacillary dysentery were 1.40 (95% confidence interval (CI): 1.16-1.69) and 1.78 (95% CI: 1.61-1.97), respectively. The regression analysis also indicated that the flood duration was negatively associated with the incidence of bacillary dysentery (with RR: 0.57, 95% CI: 0.40-0.86). Therfore, this research suggests that floods exert a significant part in enhancing the risk of bacillary dysentery in Baise. Moreover, severe floods have a higher proportional contribution to the incidence of bacillary dysentery than moderate floods. In addition, short-term floods may contribute more to the incidence of bacillary dysentery than a long-term flood. The findings from this research will provide more evidence to reduce health risks related to floods.

    Large-scale outbreaks of measles occurred in 2013 and 2014 in rural Guangxi, a region in Southwest China with high coverage for measles-containing vaccine (MCV). This study aimed to estimate the timely vaccination coverage, the timely-and-complete vaccination coverage, and the median delay period for MCV among children aged 18-54 months in rural Guangxi. Based on quartiles of measles incidence during 2011-2013, a stratified three-stage cluster survey was conducted from June through August 2015. Using weighted estimation and finite population correction, vaccination coverage and 95% confidence intervals (CIs) were calculated. Weighted Kaplan-Meier analyses were used to estimate the median delay periods for the first (MCV1) and second (MCV2) doses of the vaccine. A total of 1216 children were surveyed. The timely vaccination coverage rate was 58.4% (95% CI, 54.9%-62.0%) for MCV1, and 76.9% (95% CI, 73.6%-80.0%) for MCV2. The timely-and-complete vaccination coverage rate was 47.4% (95% CI, 44.0%-51.0%). The median delay period was 32 (95% CI, 27-38) days for MCV1, and 159 (95% CI, 118-195) days for MCV2. The timeliness and completeness of measles vaccination was low, and the median delay period was long among children in rural Guangxi. Incorporating the timeliness and completeness into official routine vaccination coverage statistics may help appraise the coverage of vaccination in China. Copyright © 2017 The Authors.

    Two hominid teeth recovered in Mohui cave are morphologically distinguished from Australopithecus in Africa, but close to Homo erectus in China. These teeth are therefore provisionally assigned to Homo erectus. The associated mammalian fauna include Gigantopithecus blacki, Nestoritherium sp., Sus xiaozhu, Sus peii and Ailuropoda microta, which are typical early Pleistocene taxa in South China. The general characteristics of the Mohui faunal assemblage are similar to the Longgupo site, which is dated to 2 Ma, implying a contemporaneity for the two sites. To date, compared with the discoveries in Africa, far fewer early Pleistocene hominid fossils have been recovered in Asia, and there are intensive controversies concerning their stratigraphic provenience and typological and temporal positions. The hominid fossils from Mohui cave, with their reliable biostratigraphic positions and distinct typological features, provide important evidence regarding the issue of early human origins and evolution.

    A previously unidentified chicken parvovirus (ChPV) strain, associated with runting-stunting syndrome (RSS), is now endemic among chickens in China. To explore the genetic diversity of ChPV strains, we determined the first complete genome sequence of a novel ChPV isolate (GX-CH-PV-7) identified in chickens in Guang Xi, China, and showed moderate genome sequence similarity to reference strains. Analysis showed that the viral genome sequence is 86.4 %-93.9 % identical to those of other ChPVs. Genetic and phylogenetic analyses showed that this newly emergent GX-CH-PV-7 is closely related to Gallus gallus enteric parvovirus isolate ChPV 798 from the USA, indicating that they may share a common ancestor. The complete DNA sequence is 4612 bp long with an A+T content of 56.66 %. We determined the first complete genome sequence of a previously unidentified ChPV strain to elucidate its origin and evolutionary status.

    Among the most important faunas in the Late Cenozoic, the Gigantopithecus faunas have received:a good deal of attention. The Gigantopithecus fauna recently discovered in Sanhe Cave consists of more than 80 mammal species, including cf. Hominidae, Pongo sp., Hylobates sp., Sinomastodon yangzien-sis, Stegodon preorientalis, Cervavitus fenqii, Dicoryphochoerus ultimus and Sus xiaozhu. It is the southernmost Gigantopithecus fauna found so far in China. Its geological age is estimated to be Early Pleistocene based on the fauna and stratigraphic correlation. The significant increase in the estimated body sizes of Ailuropoda, Gigantopithecus and Tapirus shows that the Sanhe fauna is middle Early Pleistocene, later than those from Wushan and Liucheng (early Early Pleistocene). Paleomagnetic dating of the fossil-bearing strata in Sanhe Cave gives an age of approximately 1.2 Ma. The fauna is characterized by tropical-subtropical forest types, including Pongo sp., Tupaia sp., la sp., Typhlomys intermedius, etc., and it lacks Palaearctic types. It is a typical tropical forest fauna, suggesting an en-vironment with a lush forest and a warm and humid climate. The discovery of the Sanhe Gigantopith-ecus fauna is significant for establishing the chronological stages of the Gigantopithecus faunas in China, and for discussing their origin, evolution and dynamics.

    With typical Dashiwei karst great doline (Tiankeng) located in Leye county, Guangxi in China as study area, the soil samples of different karst topography were collected and analyzed utilizing GC-MS for the 16 PAHs. Environmental factors were observed by weather instrument. The results showed that the total PAHs concentration in soils of the ground (the positive landform) of Dashiwei great doline ranged from 75.20 ng x g(-1) to 373.79 ng x g(-1), with an average of 120.70 ng x g(-1). In Dashwei great doline (the negative landform), the total PAHs concentration in soils of cliff ranged from 19.88 ng x g(-1) to 330.79 ng x g(-1), with an average of 131.86 ng x g(-1); the concentration of the bottom section ranged from 127.48 ng x g(-1) to 661.62 ng x g(-1), with an average of 395.22 ng x g(-1); and the concentration of the underground river ranged from 1132.11 ng x g(-1) to 1 749.95 ng x g(-1), with an average of 1412.39 ng x g(-1). The PAHs compounds were mainly 4-6 rings PAH. The primary sources of PAHs were pyrogenic sources. The pollution approaches were mainly atmospheric transportation and deposition. As a whole, the spatial distribution of PAHs in soils in Dashiwei doline gradually increased from the surface-the cliff-the bottom-the underground river with the increase of temperature and relative humidity. Accumulation and differentiation of PAHs in a vertical way were showed by "coal trap effect". Environmental factors influencing the distribution of PAHs in soils were majorly temperature, followed by humidity, wind direction and wind speed, and in some parts multi environmental factors worked together. The effect of the environmental factors was bigger in summer than in winter. Monitoring of PAHs discovered that the total PAHs concentration in soils of the bottom was 3.5 times higher in 2007 than in 2006. As a consequence, this study suggested that the accumulation and differentiation of karst doline was related with these important environmental factors.

    This study investigates the physical conditions (water depth, current speed, salinity, temperature) in Lianzhou Bay, a shallow coastal bay in southern China, during two expeditions in the dry and wet seasons of 2011. Based on these expedition data, basic hydrodynamic parameters like Brunt-Väisälä Frequency, Richardson Number, Rossby radius, and Resonance Period are calcu-lated. The results show that Lianzhou Bay is characterized by comparatively small quantity of freshwater input and weak stratifica-tion. Strong tides, which are spatially uniform within the bay, cause turbulent mixing. Residence time of the water is shorter in winter due to a stronger coastal current in that season. Consideration of the water movement may help to reduce the harmful ecological impact of aquaculture waste water discharge.

    Full Text Available Rising HIV infection rates have been observed among elderly people in Guangxi, China. Inexpensive aphrodisiacs are available for purchase in suburban and rural areas. This study aims to investigate the association between aphrodisiac use and increased HIV risk for middle-aged and elderly men in Guangxi.A matched case-control study of aphrodisiac use-associated HIV infection was performed among male subjects over 50 years old who were clients of low-cost commercial sex venues in Guangxi. The cases were defined as clients who were HIV-positive and two controls were selected for each case. The cases and the controls were matched on the visited sex venue, age (±3 years, number of years of purchasing sex (±3 years, and educational attainment. Subjects were interviewed and tested for HIV. Paired t-test or McNemar Chi-squared test were used to compare the characteristics between the cases and controls. A stepwise conditional logistic regression was used to identify risk factors associated with HIV infection.This study enrolled 103 cases and 206 controls. Aphrodisiac use (P = 0.02, odds ratio (OR = 1.81, 95% CI = 1.08-3.04, never using condom during commercial sex encounter (P = 0.03, odds ratio (OR = 1.82, 95% CI = 1.08-3.07, and lacking a stable partner (P = 0.03, odds ratio (OR = 1.76, 95% CI = 1.05-2.98 were found to be risk factors for HIV infection among the study groups. For subjects reporting aphrodisiac use, the frequency of purchasing sex was positively correlated with the frequency of aphrodisiac use (r = 0.3; p = 0.02.Aphrodisiac use was significantly associated with increased HIV infection risk in men over 50 years old who purchased commercial sex in the suburban and rural areas of Guangxi. Further research and interventions should address the links between aphrodisiac use, commercial sex work, condom use, and increased HIV transmission.

    Japanese encephalitis (JE) is one of the most severe kinds of viral encephalitis and is prevalent in Asia and the Western Pacific. In China, JE was first reported in the 1940s and became the main cause of viral encephalitis, including in the Guangxi Zhuang Autonomous Region. In 1951, JE was included in the Chinese mandatory disease reporting system. In the pre-vaccine era of the 1960s and 1970s, the incidence of JE continued to rise without any vaccine supply. Since JE vaccines became available in the late 1970s (MBD) and 1989 (LAV-SA-14-14-2), and as JE vaccine became freely available to patients beginning in 2008, the incidence of JE has declined significantly. Despite these gains, outbreaks continue to occur among children in rural and suburban areas. Strengthening vaccine delivery models and improving swine vaccine production are important in order to sustain continuous declines in the incidence of JE in Guangxi. Copyright © 2016 The Authors.

    Jinxiu area is tectonically located between the Cathaysia and Yangtze blocks of South China. The area has three granitic plutons, Dajin, Boquan, and Lingzu plutons. Geochemically the plutons are high-K calc-alkaline, depleted in Ba, Sr, P, and Ti and rich in Pb, with decoupled Nb and Ta, and show non-island-arc magmatic affinity. Biotite monzogranite samples collected from the Dajin, Boquan, and Lingzu plutons yield zircon SHRIMP 206Pb/238U ages of 419.0 ± 5.0 Ma, 436.0 ± 4.0 Ma, and 446.1 ± 8.2 Ma, respectively, indicating that the plutons were emplaced during the Late Ordovician to Late Silurian of the Caledonian time. The granodiorite within the Lingzu biotite monzogranite pluton yields a zircon 206Pb/238U age of 174.5 ± 1.9 Ma, indicating a superimposed Late Jurassic magmatic event. The monzogranites and their enclaves show εNd(t) values of - 14.7 to - 11.1 and - 8.0 respectively and TDM2 values of 2.1-2.4 Ga and 1.8 Ga, respectively, demonstrating that the magmas were derived from re-melted Paleoproterozoic continental crust. Based on geochronology and geochemistry of the granitic plutons, as well as regional stratigraphy and paleontology, it is concluded that any existence of oceanic crust and oceanic subduction was unlikely in the Jinxiu area and vicinity during the Paleozoic Caledonian Ordovician-Silurian time.

    One hundred twenty-eight mothers of nasopharyngeal carcinoma (NPC) cases under age 45 in Yulin Prefecture, China and 174 mothers of population controls were interviewed as part of an epidemiological study to examine childhood exposures in relation to the development of NPC. Exposure before age 2 years to a number of fermented foods was a risk factor for NPC. During weaning, intake of salted fish [relative risk (RR) = 2.6, one-sided P (P) = 0.01], salted duck eggs (RR = 5.0, P = 0.03), salted mustard green (RR = 5.4, P = 0.03), and chung choi (RR = 2.0), P = 0.003), a kind of salted root, was significantly related to an increased risk of NPC. Between ages 1 and 2 years, intake frequency of dried fish [P for linear trend test (linear trend P) = 0.002], fermented black bean paste (linear trend P = 0.0009), and fermented soy bean paste (linear trend P = 0.007) was also positively associated with NPC. A multivariate analysis of these different foods showed all except fermented black bean paste to be independently related to NPC.

    2007-01-01

    In the Lingchuan-Daoping and Xinglu Pb-Zn ore fields in northern and eastern Guangxi Autonomous Region, Pb, Cu botanogeochemical anomalies may be ascribed to the excessive amounts of Pb and Cu taken up by the root system of plants, such as China fir (Cunninghamia lanceolata Lamb. Hook), mason pine (Pinus massoniana Lamb.) and bracken fern (Pteridium aquilinum var. latiusculum). Under transmission electron microscope (TEM), the excess Pb, Cu in the leaf cells of the plants are present as high electron-density substances, which were precipitated in the leaf cells, causing phytotoxic effects by deforming and injuring cellular tissues. The sorts of toxic elements accumulating in the leaf cells are consistent with those of the botanogeochemically anomalous elements in the polluted soil where the plants grow. In addition, the plants may also be capable of resisting the invasion of excess Cu (and Pb) .

    To produce competent undergraduate-level medical doctors for rural township health centers (THCs), the Chinese government mandated that medical colleges in Central and Western China recruit rural-oriented, tuition-waived medical students (RTMSs) starting in 2010. This study aimed to identify and assess factors that influence the choice to work in rural township health centers among both RTMSs and other students from five medical universities in Guangxi, China. An internet-based self-administered questionnaire survey was conducted with medical students in Guangxi province. Multinomial logistic regression was used to identify factors related to the attitudes toward work in a rural township health center. Among 4,669 medical students, 1,523 (33%) had a positive attitude and 2,574 (55%) had a neutral attitude toward working in THCs. Demographic characteristics, personal job concerns, and knowledge of THCs were associated with the choice of a career in THCs. The factors related to a positive attitude included the following: three-year program, a rural-oriented medical program, being male, an expectation of working in a county or township, a focus on medical career development, some perceived difficulty of getting a job, having family support, sufficient knowledge of THCs, optimism toward THC development, seeking lower working pressure, and a lower expected monthly salary. Male students in a three-year program or a rural-oriented tuition-waived medical education program were more likely to work in THCs. Selecting medical students through interviews to identify their family support and intentions to work in THCs would increase recruitment and retention. Establishing favorable policies and financial incentives to improve living conditions and the social status of rural physicians is necessary.

    Background The initiation and expansion of China's national free antiretroviral therapy program has led to significant improvement of survival among its participants. Success of further scaling up treatment coverage rests upon intensifying HIV screening and efficient linkage of care. Timely CD4 cell count testing after HIV diagnosis is necessary to determine whether a patient meets criteria for antiretroviral treatment, and represents a crucial link to engage HIV-infected patients in appropriate care, which has not been evaluated in China.Methods We evaluated all patients ≥16 years who tested HIV positive from 2005 to 2009 in Yunnan and Guangxi.Multivariate Logistic regression models were applied to identify factors associated with lack of CD4 cell count testing within 6 months after HIV diagnosis.Results A total of 83 556 patients were included. Over the study period, 30 635 (37%) of subjects received a CD4 cell count within 6 months of receiving the HIV diagnosis. The rate of CD4 cell count testing within 6 months of HIV diagnosis increased significantly from 7% in 2005 to 62% in 2009. Besides the earlier years of HIV diagnosis, negative predictors for CD4 cell count testing in multivariate analyses included older age, not married or unclear marriage status,incarceration, diagnosis at sexual transmitted disease clinics, mode of HIV transmission classified as men who have sex with men, intravenous drug users or transmission route unclear, while minority ethnicity, receipt of high school or higher education, diagnosis at voluntary counseling and testing clinics, and having HIV positive parents were protective.Conclusions Significant progress has been made in increasing CD4 testing among newly diagnosed HIV positive patients in Yunnan and Guangxi from 2005-2009. However, a sizable proportion of HIV positive patients still lack CD4testing within 6 months of diagnosis. Improving CD4 testing, particularly among patients with identified risk factors, is essential to

    Full Text Available To seek the optimum fenilizion for improving economic efficiency of Guangxi crops,reducing costs of production and reducing en-vironmental pollution,the effects of different fertilizer on growth, yield and nutrient runoff losses of major economic crops (sugarcane, maizeand peanutwere studied in sloping farmland of Guangxi Province. Run-off loss of nutrient was determined in precipitation process in slopingfarmland, cultivation methods of low cost and high efficiency were sought by using SPSS statistical analysis software. The results showed thatthere was not significant difference on growth of sugarcane (maize, peanut between control and conventional fertilization. The economic out-put, biomass production, starch of maize in control were 851.42 kg·667 m-2 3 640.40 kg·667 m-2 68.40% respectively, which were higher100.62 kg·667 m -2 485.98 kg·667 m -2, 7.5% than those of maize in conventional fertilization. The fat of peanut ( contrast was higher 45 g·kg-1 than those of conventional fertilization. The runoff loss of total nitrogen, total phosphorus, total potassium, nitrate and ammonium nitro-gen was all the highest in peanut conventional fertilization, higher in sugar cane contrast, the least in maize contrast; Correlation coefficientsbetween runoff and total nitrogen, total phosphorus, total potassium, nitrate and ammonium nitrogen, for the conventional fertilization werehigher than that for the contrast of three crops. Total nutrient runoff losses of the maize contrast was the least, and nutrient runoff rate of thepeanut conventional fertilization was the largest. So maize was suitable for planting than peanut in sloping land of Guangxi Province.

    Spectral analysis is applied to geochemical data from a deep-water Permian-Triassic Boundary (PTB) section across PTB in Dongpan, Guangxi for high-resolution cyclostratigraphic research. The characteristics of the Milankovitch Cycles have been well recorded in the strata of the Dongpan section.Spectrum on Ce/La records shows especially that the ratios among its three preponderant cycles in the section are 5:2:1, which well displays the phenomenon of the sedimentary cycles driven by orbital force. The Milankovitch theory is further confirmed by the Paleozoic records.

    For a comprehensive understanding of the pollution characteristics and ecological risk of heavy metals of farmland soil in Du'an Autonomous County of Guangxi Zhuang Autonomous Region, China, this study evaluated the cadmium (Cd), arsenic (As), nickel (Ni), zinc (Zn), chromium (Cr), antimony (Sb), copper (Cu) and lead ( Pb) pollution situation using the single factor index, the Nemerow pollution index and the Hakanson ecological risk index. The results showed that heavy-metal pollution of farmland soil in Du'an County was serious. 74.6% of the soil samples had heavy metals concentrations higher than the Grade II of National Soil Environmental Quality Standard (GB 15618-1995). The over standard rates of Cd, As, Ni, Zn, Cr, Sb, Cu, Pb were 70.6%, 42.9%, 34.9%, 19.8%, 19.6%, 2.94%, 1.59%, 0.79%, respectively. Cd and As were the main contaminants in Du'an County, the pollution was far more serious than those of the national and Guangxi Zhuang Autonomous Region. In terms of the ecological risk, heavy metals of farmland soil in Du'an County showed a "middle" ecological risk, with Cd accounting for 88% of the total ecological risk. The north-west of Jiudu Town and the zone between Bao'an Town and Dongmiao Town were two areas with high ecological risk in Du'an County. The contamination of farmland soils in Du'an County was caused by two main sources, whereas the pollution of As and Sb of farmland soils near Diaojiang River was mainly caused by the upstream mining industry.

    BACKGROUND Nasopharyngeal carcinoma (NPC) is endemic in China and patient self-management is poor. Minorities may suffer from psychological problems during treatments for NPC. This study aimed to implement an intervention to promote self-efficacy of minority patients (Zhuang tribe, Guangxi, China) with NPC to improve their quality of life (QOL). MATERIAL AND METHODS This was a prospective study of 120 patients with NPC treated at the First Affiliated Hospital of Guangxi Medical University (Guangxi, China), randomized to conventional care (n=60, controls) or conventional care plus self-efficacy interventions based on health education, behavior therapy, and psychological intervention (n=60, self-efficacy group). Self-efficacy was evaluated using the general self-efficacy scale, and QOL using the EORTC QLQ-C30. The questionnaires were completed at discharge, at 6 months, and at 1 and 2 years. The primary outcome was QOL. RESULTS There was no difference in QOL at baseline. From study start to hospital discharge, overall QOL scores decreased in both groups, but this decrease was more important in the control group (controls: -39.31 vs. self-efficacy: -27.04, Pself-efficacy group. CONCLUSIONS This intervention promoting self-efficacy could increase patients' own potential and initiative, enhance their confidence and ability to solve health problems, improve their coping with adverse effects of treatments, and have positive effects on their QOL. Self-efficacy theory-based interventions could be worth popularization during the treatment and recovery of minority patients with NPC.

    More than 50 % of the world's total reserves of tungsten are in China and most tungsten deposits are located in the Nanling range in southeast China. This study explores the potential genetic relationship between tungsten-tin (W-Sn) mineralization and shallower Ag-Pb-Zn deposits in the Nanling range based on data from the Wutong deposit, Guangxi Province. The lead, oxygen, carbon, sulfur, and strontium isotopic compositions of minerals at Wutong indicate that a single crustal-derived fluid was responsible for mineralization. Wutong likely formed at relatively low temperatures (˜200-300 °C) and low pressures, as indicated by the similarity between homogenization temperatures of fluid inclusions and those estimated from S isotopic compositions of minerals. The hübnerite age (92.3-104.4 Ma) indicates that the Wutong mineralization is likely related to nearby Late Yanshanian (Cretaceous) S-type granites derived from Proterozoic crust. This mineralization event coincides with the last W-Sn mineralization event and the Cretaceous peak of mineralization in the Nanling range.

    Holcoglossum is one of the smaller genera of Orchidaceae, mainly distributed in southwest China. Some members of this genus as well as H. rupestre and H. flavescens are endemic and rare Chinese orchids. As far as we know, little work has been done concerning the relationships between the Holcoglossum plants and endophytic microorganisms. In this study, 46 culturable fungal endophytes were isolated and identified from roots of nine Holcoglossum plants collected from Yunnan, Guangxi, and Hainan provinces of China based on molecular techniques. The results showed that all strains belonged to four classes, i.e., Sordariomycetes (41.30%), Dothideomycetes (36.96%), Agaricomycetes (17.39%), Leotiomycetes (4.35%). Thirty-six strains were identified at the genus level, including Alternaria, Cladosporium, Clonostachys, Colletotrichum, Cosmospora, Cryptosporiopsis, Cylindrocarpon, Didymella, Epulorhiza (Anamorphic Tulasnella), Fusarium, Myrmecridium, Leptosphaeria, Paraconiothyrium, Phomopsis, Pyrenochaeta, and Stephanonectria. Fusarium and Epulorhiza (Anamorphic Tulasnella) were the dominant fungal endophytes. Some orchids mycorrhizal fungi as well as Tulasnella calospora and Epulorhiza sp. were found in roots. This is the first report concerning endophytic fungi from Holcoglossum plants (Orchidaceae), suggesting that endophytic fungi in Holcoglossum plants are very abundant.

    Outbreaks of measles re-emerged in Guangxi province during 2013-2014, where measles again became a major public health concern. A better understanding of the patterns of measles cases would help in identifying high-risk areas and periods for optimizing preventive strategies, yet these patterns remain largely unknown. Thus, this study aimed to determine the patterns of measles clusters in space, time and space-time at the county level over the period 2004-2014 in Guangxi. Annual data on measles cases and population sizes for each county were obtained from Guangxi CDC and Guangxi Bureau of Statistics, respectively. Epidemic curves and Kulldorff's temporal scan statistics were used to identify seasonal peaks and high-risk periods. Tango's flexible scan statistics were implemented to determine irregular spatial clusters. Spatio-temporal clusters in elliptical cylinder shapes were detected by Kulldorff's scan statistics. Population attributable risk percent (PAR%) of children aged ≤24 months was used to identify regions with a heavy burden of measles. Seasonal peaks occurred between April and June, and a temporal measles cluster was detected in 2014. Spatial clusters were identified in West, Southwest and North Central Guangxi. Three phases of spatio-temporal clusters with high relative risk were detected: Central Guangxi during 2004-2005, Midwest Guangxi in 2007, and West and Southwest Guangxi during 2013-2014. Regions with high PAR% were mainly clustered in West, Southwest, North and Central Guangxi. A temporal uptrend of measles incidence existed in Guangxi between 2010 and 2014, while downtrend during 2004-2009. The hotspots shifted from Central to West and Southwest Guangxi, regions overburdened with measles. Thus, intensifying surveillance of timeliness and completeness of routine vaccination and implementing supplementary immunization activities for measles should prioritized in these regions.

    In this Paper,the mean primary productivity of the Talung Formation in the deep-water basin(50-500 m depth)of Dongpan,Guangxi,South China,was calculated,of the content of the trace element Cu.Results showed that the primary productivity obtained was comparable with the previously-reported data for the black shale of the Phosphoria Formation,a Permian phosphate deposit in the northwest United States,and also similar to that of the modern deposit in the Cariaco basin,Venezuela.It was observed that the primary productivity increased with the enhanced abundance of algae and photosynthetic bacteria,and with the decrease in both the radiolarian individuals and the body size of brachiopods during the faunal mass extinction.This ecological coupling indicates that the changes of primary productivity are closely related to the propagation and the decline of producers(algae and bacteria),and that consumers(radiolarians and brachiopods)probably have little influence on the changes of primary productivity.

    Abundant microconchid worm tubes were extracted from the microbialites deposit near the Permian-Triassic boundary at the Zuodeng Section, Baise area, Guangxi Zhuang Autonomous Re-gion, South China. These calcareous worm tubes were studied in both petrographic thin sections and isolated specimens using optical microscope and sensitive electronic microscope (SEM), respectively. They are categorized into two morphological types: helically coiled and planispirally coiled tubes, which are assignable to Microconchus aberrans (Hohenstein, 1913) and M. utahesis (Zatońet al., 2013), respectively. The tube wall ultrastructure is characterized by laminated micrites, which distinguish the studied microconchids from comparable microgastropods or spirorbid polychaete that usually has shell ultrastructure of spar texture. The overwhelm majority of microconchids from the microbialite possess the planispirally coiled tubes. The lifestyle of extant, morphologically convergent spirorbids suggests that these planispirally coiled microconchids may have colonized in some local oxygenic oases probably produced by photosynthetic cyanobacteria in the oxygen-poor microbialite ecosystem in which they may have settled densely with high competition among various individuals and with other associated animals for oxygen consumption and food soucres. The deleterious environment condition of the mi-crobialite ecosystem immediately after the Permian-Triassic biocrisis is also indicated by various geo-chemical signals derived from the same section. Such a deleterious habitat may be inhospitable for most metazoans, but it has some local oxygenic oases that was favorable for opportunistic taxa to dwell.

    The response of mangrove ecosystems to the Asian monsoon in the future global warming can be understood by reconstructing the development of mangrove forests during the Holocene climatic optimum (HCO), using proxies preserved in coastal sediments. The total organic matter in sediments of a segmented core, with calibrated age ranges between 5.6 and 7.7 cal. ka BP and corresponding to the HCO, from the Qinzhou Bay in Guangxi, China, is quantitatively partitioned into three end-members according to their sources: mangrove-derived, terrigenous, and marine phytoplanktonic, using a three-end-member model depicted by organic carbon isotope (δ13Corg) and the molar ratio of total organic carbon to total nitrogen (C/N). The percentage of mangrove-derived organic matter (MOM) contribution is used as a proxy for mangrove development. Three visible drops in MOM contribution occurred at ca. 7.3, ca. 6.9, and ca. 6.2 cal. ka BP, respectively, are recognized against a relatively stable and higher MOM contribution level, indicating that three distinct mangrove forest degradations occurred in the Qinzhou Bay during the HCO. The three mangrove forest degradations approximately correspond to the time of the strengthened/weakened Asian winter/summer monsoon. This indicates that even during a period favorable for the mangrove development, such as the HCO, climatic extremes, such as cold and dry events driven by the strengthened/weakened Asian winter/summer monsoon, can trigger the degradation of mangrove forests.

    Based on observational and reanalysis data for 1979-2015, the possible impacts of spring sea surface temperature anomalies (SSTA) over the South Indian Ocean on the inter-annual variations of summer rainfall in Guangdong and Guangxi Provinces (i.e., the Guangdong-Guangxi area, GG) were analysed in this study. The physical mechanism behind these impacts was explored. Two geographic regions over [65°E-95°E, 35°S-25°S] and [90°E-110°E, 20°S-5°S] were defined as the western pole region and the eastern pole region, respectively, for the GG summer precipitation (PGG)-related South Indian Ocean dipole SSTA pattern (R-SIODP). The difference between springtime SST anomalies averaged over the western pole region and that averaged over the eastern pole region was defined as the R-SIODP index. The correlation between the spring R-SIODP index and GG summer precipitation can reach up to 0.52. In the spring of positive R-SIODP anomaly, southerly winds over the western pole of the R-SIODP weaken, whereas the southeast trade winds over the eastern pole strengthen. By means of the wind-evaporation-SST feedback mechanism, the enhanced southeast trade winds can weaken the evaporation over the western pole of the R-SIODP and enhance the evaporation over the eastern pole. This results in a sustained positive SSTA in the western pole of the R-SIODP and a sustained negative SSTA in the eastern pole, whereby the distribution of the SSTAs maintains until summer. The SST dipole abnormally enhances the cross-equatorial airflow near 105°E, which intensifies the anomalous anti-cyclonic circulation over South China Sea at 850 hPa and simultaneously results in abnormal enhancement of water vapour transport to GG. Additionally, the SST dipole promotes abnormal divergence in the lower troposphere and abnormal convergence in the upper troposphere over the maritime continent (MC) region. Moreover, the low-level convergence in GG is enhanced, which results in abnormal enhancement of ascending

    Clients of female sex workers (CFSWs) are a bridge population for the spread of HIV and syphilis to low or average risk heterosexuals. Most studies have examined the point prevalence of these infections in CFSWs. Limited evidence suggests that older age CFSWs are at a higher risk of acquiring sexually transmitted diseases compared with younger clients. Thus, we sought to describe long-term trends in HIV, syphilis, and hepatitis C (HCV) to better understand how these infections differ by sex worker classification and client age. We also examined trends in HIV, syphilis, and HCV among categories of female sex workers (FSWs).We conducted serial cross-sectional studies from 2010 to 2015 in Guangxi autonomous region, China. We collected demographic and behavior variables. FSWs and their clients were tested for HIV, syphilis, and HCV antibodies. Positive HIV and syphilis serologies were confirmed by Western blot and rapid plasma regain, respectively. Clients were categorized as middle age (40-49 years) and older clients (≥50 years). FSWs were categorized as high-tier, middle-tier, or low-tier based on the payment amount charged for sex and their work venue. Chi-square test for trends was used for testing changes in prevalence over time.By 2015, low-tier FSWs (LTFSWs) accounted for almost half of all FSWs; and they had the highest HIV prevalence at 1.4%. HIV prevalence declined significantly for FSWs (high-tier FSW, P = 0.003; middle-tier FSWs; P = 0.021; LTFSWs, P < 0.001). Syphilis infections significantly declined for FSWs (P < 0.001) but only to 7.3% for LTFSWs. HCV and intravenous drug use were uncommon in FSWs. HIV prevalence increased for older age clients (1.3%-2.0%, P = 0.159) while syphilis prevalence remained stable. HCV infections were halved among older clients in 3 years (1.7%-0.8%, P < 0.001). Condom use during the last sexual encounter increased for FSWs and CFSWs. Few clients reported sex with men or intravenous drug use. Clients

    This study aimed to assess ethnic differences in health-related quality of life (HRQoL) among the rural elderly, and to examine the influence of ethnic culture, residential segregation and socioeconomic development on HRQoL. A total of 6,511 rural elderly aged 60 years and older from 5,541 households in 116 villages across eight ethnic groups in Guangxi Zhuang Autonomous region were selected and assessed for HRQoL. The EQ-5D index values were calculated based on the Chinese Time Trade-Off values set. The EQ-5D descriptive system scores, visual analogue scale scores, and index values were described by ethnic group. The EQ-5D index was modeled against ethnic culture, residential segregation and socioeconomic development using villages as random effects. The median (IQR) of HRQoL among all the ethnic groups was 0.88 (0.80, 0.96). Pain/discomfort was the most prevalent problem, followed by anxiety/depression. After controlling for sociodemographic characteristics, a significant difference in HRQoL among ethnic groups persisted, but this was not true for residential segregation. Social welfare and health policies designed to improve the health of the rural elderly should focus more on older, female, less-educated, Yao minority individuals as well as lower-income households.

    Yi-hong Xie

    Full Text Available BACKGROUND: Amid numerous outbreaks of hand, foot and mouth disease (HFMD in Asia over the past decade, studies on spatio-temporal clustering are limited. Without this information the distribution of severe cases assumed to be sporadic. We analyzed surveillance data with onset dates between 1 May 2008 to 31 October 2013 with the aim to document the spatio-temporal clustering of HFMD cases and severe cases at the county level. METHODS: Purely temporal and purely spatial descriptive analyses were done. These were followed by a space-time scan statistic for the whole study period and by year to detect the high risk clusters based on a discrete Poisson model. RESULTS: The annual incidence rate of HFMD in Guangxi increased whereas the severe cases peaked in 2010 and 2012. EV71 and CoxA16 were alternating viruses. Both HFMD cases and severe cases had a seasonal peak in April to July. The spatio-temporal cluster of HFMD cases were mainly detected in the northeastern, central and southwestern regions, among which three clusters were observed in Nanning, Liuzhou, Guilin city and their neighbouring areas lasting from 1.2 to 2.5 years. The clusters of severe cases were less consistent in location and included around 40-70% of all severe cases in each year. CONCLUSIONS: Both HFMD cases and severe cases occur in spatio-temporal clusters. The continuous epidemic in Nanning, Liuzhou, Guilin cities and their neighbouring areas and the clusters of severe cases indicate the need for further intensive surveillance.

    This paper intends to give a brief overview of oral English testing for non-English major students in Guangxi Traditional Chinese Medical (TCM) University, which is located in a minority autonomous province in the southern part of P.R. China. It arises from the concrete problems facing Chinese teachers of English who feel troubled when offering an oral English test to an ever increasing number of non-English major students at the end of each semester. The frustration comes not only from the labor intensive and time consuming activity but also from the surrounding ethical issues of subjectivity by the teachers and of injustice to the students to give and receive fair marks. Moreover, there is a conflicting gap between the criteria used by the foreign native English speaking teachers and Chinese teachers of English because of their different cultural background and concept of testing. Nevertheless, an oral English test was designed and the procedures were devised, adopted, and administered to assess the student' s performance. The test and procedures, based on the national course syllabus for testing non-English majors, the level of attainment in oral English of the students, and the limited number of teaching personnel in the TCM University, utilized two different approaches. The native English speakers follow their own concept of devising formats of group testing procedures and assessment criteria forms highlighting communicative interaction. Meanwhile, the Chinese teachers of English emphasize individual rehearsed presentations and ask the student to follow up questions, to make further comment, and inquire about learning experience from the passage in order to make assessment and evaluation. Final student scores were calculated by combining daily participation of the student, the assessment foreign teacher,and the evaluation of Chinese teachers.

    Zircon U-Pb dating by the LA-ICP-MS method was applied to determining the ages of different units of the Guposhan granite complex, among which the East Guposhan unit is 160.8±1.6 Ma, the West Guposhan unit is 165.0±1.9 Ma, and the Lisong unit is 163.0±1.3 Ma in age. Much similarity in ages of the three units has thus proved that the whole Guposhan granite complex was formed in the same period of time. They were the products of large-scale granitic magmatism through crust-remelting in the first stage of the Middle Yanshanian in South China. However, the three units have differences both in petrology and in geochemistry. Besides the differences in major, trace and rare-earth elements, they are distinct in their Rb-Sr and Sm-Nd isotopic compositions. The East Guposhan unit and Lisong unit and its enclaves have a similar (87Sr/86Sr)i value of 0.7064 with an average of εNd(t)=-3.03, indicating that more mantle material was evolved in the magma derivation; whereas the West Guposhan unit has a higher (87Sr/86Sr)i value of 0.7173 but a lower εNd(t) value of -5.00, and is characterized by strong negative Eu anomalies and higher Rb/Sr ratios, suggesting that its source materials were composed of relatively old crust components and new mantle-derived components. In addition, an inherited zircon grain in the East Guposhan unit (GP-1) yielded a 206Pb/238U age of 806.4 Ma, which is similar to the ages of the Jiulin cordierite granite in northern Jiangxi and of the Yinqiao migmatic granite in Guangxi in the HZH granite zone. All this may provide new evidence for Late Proterozoic magmatism in the HZH granite zone.

    Research highlights: {yields} Soil in the investigated area is severely contaminated by mercury. {yields} Contamination of T-Hg in paddy field soils is more severe than that in dry land soils. {yields} Vertical distributions of T-Hg are different in the paddy and dry land samples. {yields} T-Hg contents in the agricultural products exceed the Chinese tolerance value. - Abstract: Mercury contamination of the environment is of worldwide concern because of its global presence and its potent neurotoxicity. Mining, smelting and the electronics industry are the main sources of Hg pollution. However, few studies have been performed to investigate systemic Hg contamination in metal mining regions. In this study, concentrations of Hg in air, farmland soil, and crops were measured in a Pb-Zn mining area in the karst region of Guangxi, China. Key factors that could affect Hg distribution, such as the fate of waste ore and waste residue, were analyzed. Geo-statistical methods were adopted to analyze the characteristics of spatial structure and distribution of Hg. The results show that Hg contamination in this region is serious. The total mercury (T-Hg) content is far higher than the Level II Limit Value of Chinese Soil Standards of 0.30 mg kg{sup -1}, showing obvious directional characteristics from WNW to ESE. Highest Hg concentrations were found in the WNW portion of the study area. The contamination of paddy soil is higher than that in dry farmland soil. The vertical distribution of T-Hg and its decrease with depth suggest that the important sources are waste water irrigation and the improper disposal of the waste ore and waste rock. The T-Hg concentrations in the agricultural products examined exceed the Chinese tolerance value (0.02 mg kg{sup -1} for rice and 0.01 mg kg{sup -1} for vegetables), indicating the seriousness of the problem. The ecological environment and the safety of food grown in this mining area are being affected, with the result that human health is

    The Bangxi-Chenxing suture zone is an important region to address the history of closure of the eastern Paleo-Tethys ocean. Among the widespread S-type granite batholiths in the SE Guangxi Province adjacent to this suture is the Nali granodiorite. Here we report zircon U-Pb ages, major and trace element geochemistry, and Sr-Nd-Hf isotope geochemistry of a newly found Middle Permian S-type granite in this region. LA-ICP-MS zircon U-Pb geochronology yields emplacement ages of 265 ± 2 to 262 ± 2 Ma for the Nali granodiorite. Both the inner and outer phases are characterized by variable SiO2 (66.91-71.39 wt.%), high Al2O3 (12.99-14.04 wt.%), K2O + Na2O (4.78-5.98 wt.%), and A/CNK values (1.11-1.50), resembling those of typical S-type granites. The rocks are enriched in Rb, Th, U and light rare earth elements with weak negative Eu anomalies, and show depletion in Nb, Ta, Ti, with typical arc-like affinity. They have relatively high (87Sr/86Sr)i ratios of 0.7228 to 0.7331, low εNd(t) values of - 13.6 to - 11.9, and low zircon εHf(t) values (- 21.9 to - 8.8). High whole-rock Nd isotopic model ages (2.00-2.02 Ga) and zircon Hf isotopic model ages (1.59-2.20 Ga), indicate that they might have been generated by partial melting of ancient lower crust with minor contribution from mantle sources. The granodiorite shows continental arc affinity and likely formed within a subduction setting. By combining previously extant data for Permo-Triassic arc-/collision-related magmatism in the Jinshajiang-Ailaoshan-Song Ma and Bangxi-Chenxing suture zones, we propose that the subduction of the eastern Paleo-Tethys might have started during Middle Permian triggered by the northward subduction of the Indochina Block (ICB) beneath the South China Block (SCB) and closure during Middle Triassic.

    Due to special hydrogeochemical characteristics of calcium-rich, alkaline and DIC-rich ( dissolved inorganic carbon) environment controlled by the weathering products from carbonate rock, the exchange characteristics, processes and controlling factors of greenhouse gas (CO2 and CH4) across water-air interface in karst water reservoir show obvious differences from those of non-karst water reservoir. Three water reservoirs (Dalongdong reservoir-karst reservoir, Wulixia reservoir--semi karst reservoir, Si'anjiang reservoir-non-karst reservoir) located in different geologic setting in Guangxi Zhuang Autonomous Region, China were chosen to reveal characteristics and controlling factors of greenhouse gas exchange flux across water-air interface. Two common approaches, floating chamber (FC) and thin boundary layer models (TBL), were employed to research and contrast greenhouse gas exchange flux across water-air interface from three reservoirs. The results showed that: (1) surface-layer water in reservoir area and discharging water under dam in Dalongdong water reservoir were the source of atmospheric CO2 and CH4. Surface-layer water in reservoir area in Wulixia water reservoir was the sink of atmospheric CO2 and the source of atmospheric CH4, while discharging water under dam was the source of atmospheric CO2 and CH4. Surface-layer water in Si'anjiang water reservoir was the sink of atmospheric CO2 and source of atmospheric CH4. (2) CO2 and CH4 effluxes in discharging water under dam were much more than those in surface-layer water in reservoir area regardless of karst reservoir or non karst reservoir. Accordingly, more attention should be paid to the CO2 and CH4 emission from discharging water under dam. (3) In the absence of submerged soil organic matters and plants, the difference of CH4 effluxes between karst groundwater-fed reservoir ( Dalongdong water reservoir) and non-karst area ( Wulixia water reservoir and Si'anjiang water reservoir) was less. However, CO2

    The Shedong W-Mo ore district in the south-central Dayaoshan Uplift of Guangxi, southern China hosts the Baoshan and Pingtoubei deposits, both of which occur in granodioritic plutons. Zircon U-Pb dating of granodiorites and its mafic microgranular enclaves (MMEs) in the Baoshan deposit yielded ages of 439.8 ± 3.2 and 441.1 ± 2.2 Ma, respectively. Granodiorites have moderate SiO2 (54.5-63.0 wt.%) and high Al2O3 (15.4-17.8 wt.%) contents, wide variations in major element ratios, significant rare earth element fractionation, and small negative Eu anomalies. They are rich in Th, U, Zr, and Hf, and depleted in Ba, Nb, and Ti. Their initial 87Sr/86Sr, εNd(t), and εHf(t) values are in the range of 0.7086-0.7091, -5.2 to -6.6 and -6.3 to +1.6, respectively. Rounded or lenticular MMEs have relatively low silica and high mafic components, depletion in Eu, Sr, and Zr, and marked negative Eu anomalies. Rb/Sr and Nb/Ta ratios, and εNd(t) and εHf(t) values of the MMEs are higher than those of host granodiorites, indicating a different magmatic source. Zircon U-Pb dating of the unexposed granodiorite porphyry in the Pingtoubei deposit yielded an age of 440.0 ± 1.7 Ma. The granodiorite porphyries have high SiO2 and low K2O, FeOT, and MgO contents, with similar trace element features to the granodiorites at the Baoshan deposit, although the former has small negative Eu anomalies. Its initial 87Sr/86Sr values range from 0.7162 to 0.7173, εNd(t) values from -8.7 to -12.3, and εHf(t) values from -7.8 to +1.3, indicative of a crustal source. Nd and Hf two-stage model ages of the granodiorites, MMEs, and granodiorite porphyries have a narrow range between 1.3 and 2.2 Ga. We propose that the granodiorites and MMEs at the Baoshan deposit were produced through re-melting of middle Proterozoic crust as a result of underplating of mantle-derived magmas in a transitional compression-to-extension tectonic setting. Mantle-derived magmas provided the heat and material for the formation

    Full Text Available Abstract Background Hospital preparedness is critical for the early detection and management of public health emergency (PHE. Understanding the current status of PHE preparedness is the first step in planning to enhance hospitals' capacities for emergency response. The objective of this study is to understand the current status of hospital PHE preparedness in China. Methods Four hundred hospitals in four city and provinces of China were surveyed using a standardized questionnaire. Data related to hospital demographic data; PHE preparation; response to PHE in community; stockpiles of drugs and materials; detection and identification of PHE; procedures for medical treatment; laboratory diagnosis and management; staff training; and risk communication were collected and analyzed. Results Valid responses were received from 318 (79.5% of the 400 hospitals surveyed. Of the valid responses, 264 (85.2% hospitals had emergency plans; 93.3% had command centres and personnel for PHE; 22.9% included community organisations during the training for PHE; 97.4% could transport needed medical staff to a PHE; 53.1% had evaluated stockpiles of drugs; 61.5% had evaluated their supply systems; 55.5% had developed surveillance systems; and 74.6% could monitor the abnormity(See in appendix. Physicians in 80.2% of the analyzed hospitals reported up-to-date knowledge of their institution's PHE protocol. Of the 318 respondents, 97.4% followed strict laboratory regulations, however, only about 33.5% had protocols for suspected samples. Furthermore, only 59.0% could isolate and identify salmonella and staphylococcus and less than 5% could isolate and identify human H5N1 avian flu and SARS. Staff training or drill programs were reported in 94.5% of the institutions; 50.3% periodically assessed the efficacy of staff training; 45% had experts to provide psychological counselling; 12.1% had provided training for their medical staff to assess PHE-related stress.

    This paper reports the recent discovery of 176 stone artifacts, including two handaxes (bifacial large cutting tools), which are preserved in the laterized sediments of terrace 4 of the Youjiang River at the Nanbanshan locality of the Damei site in the Bose basin, south China. Their characteristics are similar to Paleolithic stone artifacts discovered from other sites in this basin. The handaxes, picks and other stone artifacts are associated with 155 tektite pieces found in the same horizontal layer. These fresh, unabraded and sharp-edged tektites were buried immediately after the airfall event. This provides fur-ther evidence that the Bose stone artifacts and the tektites were deposited simultaneously around 0.8 Ma. More stone artifacts were also unearthed above the tektite layer, indicating that early humans in the area survived the event.

    冠斑犀鸟(Anthracoceros albirostris albirostris)属于国家Ⅱ级重点保护野生动物,并且是亚洲热带地区重要的种子传播者.冠斑犀鸟在20世纪70年代以前曾广布广西西南部中越边境地区,但其分布范围持续萎缩,2000年以后只残存于3个孤立的分布点,而西大明山林区一直是冠斑犀鸟的主要分布点.为了解此物种在广西的最新分布状况,我们于2009年在广西西大明山自然保护区首次进行了冠斑犀鸟的同步调查,同时调查了当地犀鸟可利用的植物资源.结果显示至少有50只冠斑犀鸟在当地栖息,是广西目前最大的种群,但数量明显呈下降趋势.本文记录了124种犀鸟可潜在利用的植物,探讨了广西犀鸟面临的威胁,并呼吁国家有关部门和科学界加强对中国犀鸟保育研究的关注.%The oriental pied hornbill (Anthracoceros albirostris albirostris) is a State Protected Species and also an important seed dispersal agent in Tropical Asia.Recent studies show that the range of oriental pied hornbill in Guangxi has decreased significantly in the last decades.During the 1970s the species was widespread along the Sino-Vietnamese border but since the 2000s it has been confined to only three isolated areas.Although the population has declined substantially,Xidamingshan still supports the largest hornbill population known in Guangxi.In order to understand the current status of the species in Guangxi,China,we conducted a simultaneous population survey in Xidamingshan Nature Reserve in 2009.At least,fifty birds were recorded during survey and 124 plant species are identified as potential food source of the bird.Human disturbance and hunting are the main threats to the species in Guangxi.Further research and conservation of the species are urgently required.

    Heavy metal contamination of metal-mined soils is a widespread problem in China. In the restored (over 20 years) Lipu manganese mineland, 36 plant species from 22 families were found colonizing, some of which were planted agronomic ones. Heavy metal concentrations in tailings were very high. Minesoils were basically unpolluted, but soils in the remaining mining area and in the vicinity of tailings dumps were polluted by Cd and Mn. Measurements of metal contents in dominant plants showed they were close to those of other mineland plants. Plants tended to have a higher Cd accumulation (as reflected by Biological Accumulation Coefficient) from soil, but have a higher Mn translocation (as indicated by Biological Transfer Coefficient) to aboveground parts. The Chinese chestnut and sugarcane cultivated on the reclaimed mineland were not safe for human consumption, and this agricultural restoration pattern should be carefully reconsidered. - Soils of a restored manganese mineland are basically unpolluted, but direct cultivation of edible agronomic crops may be a health risk for humans.

    The method of principal component analysis was applied to systematical research on the soil multi-media environment, including soil, surface water, ground water, waterbody sediment and agricultural crops, as well as pollution-inducing wastewater, mullock (or waste ore) and slag in the periphery of a large-sized Pb-Zn mining and smelting plant in a karst area of Guangxi Zhuang Autonomous Region. The results revealed that soils in the area studied have been heavily polluted by Cd, Zn, Pb and Hg, and the levels of these metals in the samples of agricultural crop greatly exceed the standards. The above-mentioned pollutants exist in all soil-multi-media environments. The mullock, slag, wastewater, surface water, ground water, soil, and agricultural crops constitute a composite ecological chain. Therefore, the improper disposal of mullock and slag, and the use of polluted wastewater for agricultural irrigation are the main causes of soil pollution. Heavy metals in the soil have three transition progresses: point (improved soil with slag, ground water inflow plot), linear (river transition) and non-point transition (regional pollution by slag) patterns, and the tailing yard is the most important locus for heavy metals to release into the environment.

    Guangxi Zhuang Autonomous Region is an excellent area for tilapia breeding in China,and the development of tilapia industry has received high attention of both the state and Guangxi government. The foreign exchange earning is an essential industrial form of tilapia industry in Guangxi. Thus,enhancing the competitiveness of export-oriented tilapia processing is of great significance to the development of tilapia industry. On the basis of field survey,this paper analyzed current situation of export-oriented tilapia processing in Guangxi. At present,tilapia processing industry in Guangxi has realized preliminary standardization,large-scale and grouping,but it is still faced with some problems and challenges,such as low industrialization level,no balanced marketing,and imperfect product quality safety monitoring measures. Therefore,it is required to create favorable environment for export-oriented tilapia processing industry in Guangxi through enhancing policy support,increasing financial input and supporting tilapia processing leading enterprises.

    The domestic chicken (Gallus gallus domesticus) is an excellent model for genetic studies of phenotypic diversity. The Guangxi Region of China possesses several native chicken breeds displaying a broad range of phenotypes well adapted to the extreme hot-and-wet environments in the region. We thus evaluated the genetic diversity and relationships among six native chicken populations of the Guangxi region and also evaluated two commercial breeds (Arbor Acres and Roman chickens). We analyzed the sequences of the D-loop region of the mitochondrial DNA (mtDNA) and 18 microsatellite loci of 280 blood samples from six Guangxi native chicken breeds and from Arbor Acres and Roman chickens, and used the neighbor-joining method to construct the phylogenetic tree of these eight breeds. Our results showed that the genetic diversity of Guangxi native breeds was relatively rich. The phylogenetic tree using the unweighed pair-group method with arithmetic means (UPGAM) on microsatellite marks revealed two main clusters. Arbor Acres chicken and Roman chicken were in one cluster, while the Guangxi breeds were in the other cluster. Moreover, the UPGAM tree of Guangxi native breeds based on microsatellite loci was more consistent with the genesis, breeding history, differentiation and location than the mtDNA D-loop region. STRUCTURE analysis further confirmed the genetic structure of Guangxi native breeds in the Neighbor-Net dendrogram. The nomenclature of mtDNA sequence polymorphisms suggests that the Guangxi native chickens are distributed across four clades, but most of them are clustered in two main clades (B and E), with the other haplotypes within the clades A and C. The Guangxi native breeds revealed abundant genetic diversity not only on microsatellite loci but also on mtDNA D-loop region, and contained multiple maternal lineages, including one from China and another from Europe or the Middle East.

    Objective To establish a fast and simple genetic diagnosis technique based on a reliable, short tandem repeat (STR) genetic marker system for the detection of hemophilia A carriers in Guangxi, China. Methods Fluorescent PCR and + capillary electrophoresis were used for allele genotyping at three intragenic/extragenic STR loci (F81ntl3, DXS1073, and DXS9901) of FVIII gene in the members of 10 hemophilia A families in Guangxi, so as to evaluate the diagnostic efficiency of the STR genetic marker system for detection of hemophilia A carriers. Then the STR genetic marker system was used to detect hemophilia A carriers among examinees. Results In the 10 hemophilia A families, 11 confirmed female carriers had the same allele fragment lengths at the three STR loci (F8Intl3, DXS1O73, and DXS9901) as the probands. Of the 8 females examined, 5 had allele fragments at the three STR loci (F8Intl3, DXS1073, and DXS9901) which were identical to those of the probands, and thus they were diagnosed as hemophilia A carriers.

    East,dated to 115ka,can be confirmed as modern human anatomically,which coexisted with Neanderthals for a long time. Although hominin fossils are relatively rich during Late Pleistocene in China, unfortunately, they usually lack clear context, reliable dating and explicit anatomical characteristics of modern human. Even so, these hominin fossils are significant for the study of origin of modern human in East Asia. Recent recoveries derive from Huanglong Cave, Hubei, where several human teeth associated with stone artifacts were unearthed, and more recent from Zhiren Cave, Guangxi Zhuang Autonomous Region where a fragmental mandible was found. These hominin fossils are of modern human-characteristics in anatomy and dated around lOOka, which is close to that of the Middle East. This also provides crucial evidence for modern human origin and evolution. Thus,with the constant discoveries of the fossil materials in East Asia, we have reason to expect that the time, place and evolutionary model of modern human will be further studied.%本文对广西北部平乐县鸡母岩发现的人类牙齿化石进行了研究,认为形态学上区别于中国直立人和早期智人,而与晚期智人相似.与之共生的哺乳动物群,包含绝迹种猩猩、大熊猫和绝灭种东方剑齿象、中国貘,指示其时代在晚更新世.平乐人类化石的发现,为研究现代人类的起源和演化提供了新的化石证据.

    According to the household consumption data of urban residents in Guangxi Statistical Yearbook in the year 2009, the ELES (Extended Linear Expenditure System) is used to analyze the consumption structure, the propensity to consume, and the consumer flexibility of urban residents in Guangxi Zhuang Autonomous Region of China in the year 2008. Result shows that urban residents in Guangxi has relatively low propensity to consume. And their consumption, especially the middle and low-income families, is mostly concentrated in food, cloth, lodging and other basic necessities of life, which account for more than a half of their income. Based on this, corresponding suggestions are put forward to enlarge the consumption demand of urban residents in Guangxi, such as increasing the regulation of income redistribution, minimizing the gap between the rich and the poor, enhancing the overall consumption level, cultivating the consumption hot spots for the urban residents, and actively guiding the enjoyable consumption.

    In China canine rabies poses a serious public health problem in that human mortality ranks the second highest globally. While rabies health education interventions are advocated by WHO to be critical components of modern rabies control and prevention programs, available studies have not adequately investigated the relative efficacy of their implementation in at-risk populations. This study aims to measure and compare the effect on knowledge and protective behavior towards rabies of health education interventions that include a novel Short Messaging Service via cell phone (SMS) and rabies health information sessions (IS). The study used a between-subject design involving repeated measures of rabies-related KAP (knowledge, attitude and practice). A total of 350 randomly selected villagers were randomly allocated into three intervention (SMS, IS and SMS + IS) and one control group. The content of SMS and IS covered topics about rabies prevention and route of transmission. The SMS intervention consisted of ten separate messages delivered three times two weeks after the pretest; the IS intervention was conducted once immediately after the pretest. A validated questionnaire was used to capture demographic information and KAP information. Ordinary Least Squares regression was used to contrast the effects of interventions. Our results indicate that overall SMS outperforms IS at improving knowledge and protective behavior against rabies. Our results suggest that a combined intervention of SMS and IS can result in higher scores than any of the two in isolation. The impact of SMS, IS and SMS + IS is greatest on knowledge, followed by attitude and practice scores. This study demonstrated that health communication modes based on SMS, IS and a combination of the two are all effective to improve rabies-related KAP in the short term. These findings highlight the potential usefulness of SMS as an additional tool for public health communication and promotion; further studies

    The yield data of 24 sugarcane cultivars grown at 14 locations were analyzed in combination of analysis of variance and heritability-adjusted GGE (HA-GGE) biplot to study the genotype (G), environment (E), and genotype×environment (GE) effects on yield variation. Besides, the 14 test locations were evaluated for their discriminating ability, representative ability and desirability index, and grouped into ecological zones based on the GGE biplot patterns. The results showed that the effect of envi-ronments on yield was higher than that of G and GE, and the genotype by location interaction was the greatest while genotype by year interaction the least within GE. The GGE biplot analysis revealed that Suixi of Guangdong Province and Chongzuo of Guangxi Province were the two most ideal test locations for developing and/or recommending cultivars for the whole region. In contrast, Laibin and Liuzhou of Guangxi Province were undesirable for selection and variety recommendation for the whole re-gion. The other relatively desirable test locations included Fuzhou and Zhangzhou of Fujian Province, Zhanjiang of Guangdong Province, Baoshan, Lincang, and Ruili of Yunnan Province, followed by the four less desirable test environments, Baise and Hechi of Guangxi Province, Lingao of Hainan Province and Kaiyuan of Yunnan Province. According to the results from HA-GGE analysis, the sugarcane ecological zones in China could be divided into three subregions, the first is the ecological zone of south-ern China inland, represented by Baise, Hechi, Laibin and Liuzhou of Guangxi Province, the second one is the ecological zone of southwest plateau, represented by Baoshan, Kaiyuan, Lincang and Ruili of Yunnan Province, and the third one is the ecological zone of coastal southern China, represented by Fuzhou and Zhangzhou of Fujian Province, Zhanjiang and Suixi of Guangdong Province, and Chongzuo of Guangxi Province.

    Moderate resolution imaging spectroradiometer (MODIS) data are very suitable for vast extent, long term and dynamic drought monitoring for its high temporal resolution, high spectral resolution and moderate spatial resolution. The composite Enhanced Vegetation Index (EVI) and composite land surface temperature (Ts) obtained from MODIS data MOD11A2 and MOD13A2 were used to construct the EVI-rs space. And Temperature Vegetation Dryness Index (TVDI) was calculated to evaluate the agriculture drought in Guangxi province, China in October of 2006. The results showed that the drought area in Guangxi was evidently increasing and continuously deteriorating from the middle of September to the middle of November. The TVDI, coming from the EVI-rs space, could effectively indicate the spatial distribution and temporal evolution of drought, so that it could provide a strong technical support for the forecasting agricultural drought in south China.

    Objective To distinguish two Bithynia species,Bithynia fuchsiana and Bithynia robusta collected from Heng County,Guangxi Zhuang Autonomous Region,by using morphological and DNA barcoding methods. Methods The adult B. fuchsiana and B. robusta were collected from the biotope such as rivers,ditches and ponds in Heng County of Guangxi Zhuang Autonomous Region,China. The two species specimens were identified by measuring shell morphological parameters,compar⁃ing the characters of the male reproductive system,and using the COI gene barcoding technique and building phylogenetic tree. Results B. fuchsiana and B. robusta were similar morphologically in the shell appearance;they had the similar snail height, snail width,shape and male reproductive structure. The DNA sequence analysis showed that the COI gene of the two Bithynia species had low sequence divergence with 11 variation sites among 22 sequences. The length of the COI gene segment was 517 bp and no insertion sites and deletion loci after sequence edited. All individuals of the two species gathered to one clade in the phylogenetic tree based on COI gene. Conclusion According to the evidence of morphology and COI gene coding sequence,B. fuchsiana and B. robusta from Heng County,Guangxi Zhuang Autonomous Region,are likely to be the same species.%目的:应用形态与DNA条形码技术鉴别广西横县两种形态相似、栖息生境相同的豆螺——硬豆螺(Bithynia ro⁃busta)与赤豆螺(Bithynia fuchsiana)。方法在广西横县的河流、沟渠和池塘等生境采集赤豆螺和硬豆螺,观察两种豆螺的外部形态并测量其主要参数,比较螺的雄性生殖系统形态。此外,应用基于COI基因的DNA条形码技术进行螺种鉴别,并构建系统树。结果共采获两种豆螺29个,包括19个赤豆螺和10个硬豆螺。两种豆螺的个体外形基本一致,其壳高、壳宽及形状相近,雄性生殖系统形态相似

    Jinlun Cave in Mashan County and Yilingyan Cave in Wuming County are ~120km and ~60km north of Nanning in Guangxi Province under influence of both Indian Monsoon and North Western Pacific Monsoon. Several stalagmites have been dated by AMS 14C dating method since 230Th/U is not applicable due to very low U contents. Twenty (20) AMS 14C dates on Stalagmite JL20131005-10 (10-cm long) show "Bomb carbon curve", spanning the past 60 years. Lamination counting further confirms the chronology. Thirty nine (39) AMS 14C dates on Stalagmite JL20131005-12 (33-cm long) reveal 2300-year continuous growth. Stalagmite YLY20130727-12 (10-cm long) from Yilingyan Cave covers a continuous record of past 2300 years. All studied stalagmites in the caves contain low dead carbon fractions. The annual resolution δ18O and δ13C records obtained from the stalagmites allow us to compare the stalagmite δ18O records with the instrumental rainfall and temperature records, Pacific Decadal Oscillation (PDO), Southern Oscillation Index (SOI), and Sunspot variation, etc. The δ18O and δ13C records exhibit relatively good correlation throughout the time, indicating climatic control on vegetation change. Based on the high-resolution δ18O and δ13C records, we interpret that dry climatic conditions and poor vegetation coverage during periods of AD1880~1850, 1700~1600, 1460~1320, 1210~1280, 860~750, 540~420, 300~220, and AD100~0 shown by increased δ18O and δ13C. The δ18O and δ13C were strongly depleted during the Medieval Warm Period (MWP between AD900 and AD1100) and Current Warm Period (CWP, since AD1900), reflecting strongly increased East Asian Summer Monsoon. After AD1900, the δ13C decreased about 6‰, perhaps indicating human impact on surface vegetation. The δ18O records from the study area are comparable to the published WX42B δ18O record of Wanxiang Cave (Zhang et al., 2008) except for the period of AD1400~1850. Our study suggests that AMS 14C dating is an alternative method for

    Sinkhole collapse is the main geohazard for Qingyun village, Guigang, Guangxi Autonomous Region, China. It is necessary to study the characterization criteria of Karst collapse hazard. So the water levels of residential and community wells were monitored. By comparison with real-time monitoring of groundwater level in a reference ar-ea with no sinkhole collapsing event, a characterization process was developed to assess sinkhole hazards in the Qingyun village area. Characterization criteria include 2 factors: daily water level fluctuations of Karst aquifer, recov-ery of water level in Karst aquifer, and maximum declining rate of water level in Karst aquifer. This characterization process could be used to assess impact of construction work on ground water, and to obtain its impact level, to judge the possibility of Karst collapse hazard and prevent the development of soil voids and human-induced sinkholes in ac-tive Karst areas.%针对广西贵港覃塘镇青云村岩溶塌陷问题,开展该区岩溶塌陷水动力条件的危险性评价指标研究工作.通过实时、高分辨率的自动化监测设备对该区的岩溶地下水进行了监测.结果表明,岩溶地下水的变化是该地区岩溶塌陷发生的主要诱发因素.通过对比抽水活动强烈,无岩溶塌陷事件发生地区的地下水动态监测资料,综合分析提炼出岩溶塌陷水动力条件危险性评价指标,即:岩溶水日波动最大幅度及水位恢复时间、岩溶水位瞬时最大下降速度.该指标可应用于评价工程活动对地下水的影响,实时获取工程活动对地下水的影响程度,判断岩溶塌陷的可能性,反过来也可指导工程活动,减少灾害的发生及损失.

    Objective To investigate the acceptability and influencing factors of pre-exposure prophylaxis ( Pr-EP) for human immunodeficiency virus ( HIV) among female sex workers ( FSWs) in Sichuan, Xinjiang and Guangxi of China. Methods FSWs selected from Sichuan, Xinjiang and Guangxi were surveyed with questionnaires. A total of 1 478 questionnaires were completed, among which 1 469 (99.39%) were effective. The survey mainly concerned with the awareness and acceptability of FSWs on Pr-EP. Results After introduction to Pr-EP by the investigators, under the precondition that Pr-EP was effective and safe, 997(67.9%) FSWs accepted Pr-EP, and there was no significant difference in the acceptability among FSWs in three regions ( P > 0. 05). Univariate x2 analysis and Logistic regression analysis revealed that self-evaluation of risks (OR = 1. 776, P = 0. 005), regular condom use in sex service ( OR = 1. 346, P = 0. 000), frequency of condom use during the latest three times of sex service (0/1 = 1.519, P = 0. 003), drug use to prevent sexually-transmitted disease ( OR = 1. 185, P = 0. 025), refusal of having sex with those without condom use (0R = 1 479, P = 0. 009) and advising peers to use Pr-EP (OR = 5. 618, P = 0. 000) were influencing factors of acceptability of Pr-EP. FSWs mainly concerned of the security, effectiveness and cost of Pr-EP. Conclusion FSWs with regular condom use are more likely to accept Pr-EP. Pr-EP related knowledge should be well exposed among FSWs to increase the awareness and acceptability. Peer education may be a better way to improve the acceptability of Pr-EP.%目的 了解我国四川省、新疆维吾尔自治区、广西壮族自治区女性性工作者( FSWs)对暴露前预防用药(Pr-EP)预防人类免疫缺陷病毒(HIV)感染的接受意愿及其影响因素.方法 采用问卷调查的形式,调查对象为四川省、新疆维吾尔自治区、广西壮族自治区的FSWs.调查完成问卷1 478份,有效问卷1 469份(占99.39%).调查

But seasonal drought occurs very frequently because of spatio-temporal nonuniform distribution of rainfall. Seasonal drought has a rather large influence on the water resources, industrial production, and human life, especially on the agricultural production of Guangxi. The research there has been mostly aimed at some characteristics of a certain domain (such as agriculture) in the application .And some evaluation processes too depended on subjective experience or a simple formula, and did not comprehensively consider the influence to society’s economy and environment of drought disaster, the vulnerability of the disaster bearing body, and the ability to prevent and reduce disaster. In order to strengthen the risk assessment and emergency management capability of the autumn drought disasters of Guangxi, an autumn drought risk assessment indicator system was established, and its indicators were determined according to drought risk, sensitivity of disaster environment, vulnerability of disaster bearing body, ability of

HBV genotypes were determined by PCR-microcosmic nucleic acid cross-ELISA. YMDD mutations were detected by microcosmic nucleic acid cross-nucleic acid quantitative determination. HBV DNA was detected by fluorescence ratio PCR analysis.LAM was given to 81 cases and its curative effect was observed by measuring ALT, HBV DNA load, HBeAg, and HBeAg/HBeAb conversion rate.RESULTS: HBV genotypes B, C, D, and non-classified genotypes were found in Guangxi Zhuang population.accounting for 25.6%, 47.4%, 58.3%, and 16.0%,respectively. Seventy-four cases were CD-, CB-, BD-mixed genotypes (47.7%). Forty-six (29.5%) cases had YMDD mutations. Genotype B was mostly found in mild and moderate CHB patients. Genotypes C, D and mixed genotype mostly occurred in severe CHB cases.Genotypes D and CD HBV-infected patients had higher ALT and HBV DNA than patients with other types of HBV infection. There was no significant difference among the genotypes in YMDD mutations, clinical types, ALT and HBV DNA level. Non-classified types geno had a significantly lower positive rate of HBeAg than other genotypes (x2= 12.841, P<0.05). There was no significant difference in ALT recovery rate, HBV DNA load, HBeAg,and HBeAg/HBeAb conversion rate, 48 wk after LAM treatment between groups of genotypes D, CD, and nonclassified type.CONCLUSION: Genotypes B, C, and D, non-classified and mixed genotype of HBV are identified in the Guangxi Zhuang population. Variations in genotypes are associated with clinical severity and serum ALT levels, but not with YMDD mutation or HBV DNA load.Therapeutic effects of LAM

    International trade and investment have been two major topics in the field of interna-tional economics. They are also two main ways to deepen foreign economic ties. With the rapid de-velopment of the China—ASEAN free trade area and the Beibu Gulf Economic Zone, international trade and investment have had an important influ-ence on the ethnic areas of Guangxi. Guangxi is a frontier and coastal minority area, and as well as an important window opening on to the ASEAN e-conomic sphere and economic hinterland. It has great power and vitality for economic development within the ASEAN economic sphere. However, Guangxi, if compared with domestic developed are-as, is a relatively backward region within China’s economy. Its level for utilizing FDI( Foreign Direct Investment) lags behind, and its foreign trade vol-ume has definitely lagged far behind that in the more developed coastal provinces. This has severe-ly restricted the economic and social transformation of the Guangxi, and is an important obstacle for re-alizing a “well -off” society in ethnic areas. In recent years, resulting in the increasing external dependency in ethnic areas, the development of foreign investment has kept steady. This has played an important role in promoting technological progress and adjusting the industrial structure in ethnic areas. At the same time, foreign investment has also increased the speed of the ethnic minority areas’ ability to absorb advanced technology and management experience. This, in turn, has had great significance for further exploring international markets. However, the various regions in China have differences in their utilization of FDI and for-eign trade, so, effective an evaluation for exploring foreign trade and FDI has had a specific effect on the economic growth in ethnic areas, which can provide certain reference points for ethnic minority areas to formulate economic policy. Based on the relevant data of exports, imports and economic growth collected

    "Surplus income" of farmers has been increasing steadily with the marked improvement of rural economy. However,development of rural financing market in China is rather backward. To satisfy the financing requirement of farmers and meet the demand of the construction of new countryside as well as harmonious society,development of financing market in rural area is eager to be quickened. Taking Guangxi Autonomous Region as an example,there are problems in rural investing and financing development. Firstly,farmers are in lacking of accurate understanding of investing and financing. Secondly,investors in rural area lack professional knowledge about financing generally. Thirdly,rural area has underdeveloped information degree as well as imperfect investing and financing environment. Fourthly,there are no financial products developed for rural area. Fifthly,economic development is unbalanced and relatively underdeveloped in rural area. Lastly,rural financial market has long been neglected by financial intermediaries. In order to cope with these problems,firstly,farmers should be assisted to establish accurate financial awareness and master necessary financial knowledge. Secondly,local intermediaries like securities firms and banks should be encouraged to exert impact on rural financial market. Thirdly,financial products suitable for Guangxi rural area are to be developed. Fourthly, construction and perfection of rural financial market should be quickened. Lastly,rural economic development should be quickened to enlarge capital source of financing.

    Objective: To understand the epidemiological characteristics and viral sources of dengue fever outbreak in Guangxi Zhuang Autonomous Region (Guangxi) in 2014. Methods: A combined analysis of epidemiological characteristics and genetic characteristics were performed in this study. The time, population and area distributions of the cases were analyzed. Serum samples were collected from dengue fever cases to detect NS1 antigen by using commercial ELISA kits according to the guideline of the manufacture. RT-PCR assay was conducted to detect dengue virus in NS1 positive samples. Phylogenetic tree based on E gene sequence of dengue virus were further analyzed. Results: During September-December 2014, an outbreak of dengue fever caused by dengue virus type 1 and 2 occurred in Guangxi, a total of 854 cases were reported without death, including 712 laboratory confirmed cases and 142 clinical diagnosed cases, in which 79.63% (680/854) occurred during 22 September-21 October 2014. All the cases had typical dengue fever symptoms. Most cases occurred in Nanning and Wuzhou, in which 83.61% (714/854) were in age group 15-59 years; 46.60% (398/854) were staff or people engaged in commercial service. A total 526 serum samples were tested for dengue virus serotype by RT-PCR assay. Among 414 positive samples, 345 were positive for dengue virus type 1 (DENV-1) and 69 were positive for dengue virus type 2 (DENV-2), no DENV-3 and DENV-4 were detected. The results of phylogenetic analysis of E gene sequence indicated that the sequences of 99.12%(113/114) of DENV-1 strains in Nanning in China shared 100.00% homology with the isolate (SG EHI D1/529Y13) from Singapore in 2013, which belonged to the genotype Ⅰ; All the DENV-2 isolates from Wuzhou shared 99.80% homology with the isolate (D14005) from Guangdong province, which belonged to genotype Cosmopolitan. Conclusions: The outbreak was caused by DENV-1 from Singapore and DENV-2 from Guangdong province in China. It is necessary to

    2013-12-01

    Sea level rise caused by global climate change will have significant impacts on coastal zone. The mangrove ecosystems occur at the intertidal zone in tropical and subtropical coasts and are particularly sensitive to sea level rise. To study the responses of mangrove ecosystems to sea level rise, assess the impacts of sea level rise on mangrove ecosystem and formulate the feasible and practical mitigation strategies are the important prerequisites for securing the coastal ecosystems. In this research, taking the mangrove ecosystems in the coastal zone of Guangxi province, China as a case study, the potential impacts of sea level rise on the mangrove ecosystems were analyzed by adopting the SPRC (Source-Pathway- Receptor- Consequence) model. An index system for vulnerability assessment on coastal mangrove ecosystems under sea level rise was worked out, in which rate of sea level rise, subsidence/uplift rate, habitat elevation, daily inundation duration, intertidal slope and sedimentation rate were selected as the key indicators according to the IPCC definition of vulnerability, i.e. the aspects of exposure, sensitivity and adaptation. A quantitatively spatial assessment method based on the GIS platform was established by quantifying each indicator, calculating the vulnerability index and grading the vulnerability. The vulnerability assessment based on the sea-level rise rates of the present trend and IPCC A1F1 scenario were performed for three sets of projections of short-term (2030s), mid-term (2050s) and long-term (2100s). The results showed at the present trend of sea level rise rate of 0.27 cm/a, the mangrove ecosystems in the coastal zone of Guangxi was within the EVI score of 0 in the projections of 2030s, 2050s and 2100s, respectively. As the sedimentation and land uplift could offset the rate of sea level rise and the impact of sea level rise on habitats/species of mangrove ecosystems was negligible. While at the A1F1 scenario with a sea level rise rate of 0

    Full Text Available Knowledge about genetic diversity and relationships among germplasms could be an invaluable aid in diospyros improvement strategies.This study was designed to analyze the genetic diversity and relationship of local and natural varieties in Guangxi Zhuang Autonomous Region of China using start codon targeted polymorphism (SCoT markers. The accessions of 95 diospyros germplasms belonging to four species Diospyros kaki Thunb, D. oleifera Cheng, D. kaki var. silverstris Mak, and D. lotus Linn were collected from different eco-climatic zones in Guangxi and were analyzed using SCoT markers.Results indicated that the accessions of 95 diospyros germplasms could be distinguished using SCoT markers, and were divided into three groups at similarity coefficient of 0.608; these germplasms that belong to the same species were clustered together; of these, the degree of genetic diversity of the natural D. kaki var. silverstris Mak population was richest among the four species; the geographical distance showed that the 12 natural populations of D. kaki var. silverstris Mak were divided into two groups at similarity coefficient of 0.19. Meanwhile, in order to further verify the stable and useful of SCoT markers in diospyros germplasms, SSR markers were also used in current research to analyze the genetic diversity and relationship in the same diospyros germplasms. Once again, majority of germplasms that belong to the same species were clustered together. Thus SCoT markers were stable and especially useful for analysis of the genetic diversity and relationship in diospyros germplasms.The molecular characterization and diversity assessment of diospyros were very important for conservation of diospyros germplasm resources, meanwhile for diospyros improvement.

    A study was conducted on variations in chemical composition of surface and spring water in a typical karst peak cluster-depression catchment, Northwest Guangxi, during two rainfall events on Aug. 23 and Aug. 24, 2007. Both spring and surface waters displayed a quick response to the rainfall in terms of water chemistry. During the rainfall events, electronic conductivity (EC) and concentrations of both dominant cations and anions, carbonate saturation index (SI) and carbon dioxide pressure (pCO2) decreased in the surface water soon after rainfall, while those factors in the spring water generally showed opposite variation trends. The solutes transportation rates of spring and stream flows increased during the rainfall period, but didn't show a positive relationship with rainfall intensity during continuous rainfall, revealing that besides the rain dilution effect and soil CO2 effect, the pre-event water stored in the soil vadose zone, as well as the amounts of exchangeable ions may affect the transportation of ions of both spring and stream flows in the karst peak cluster-depression catchment during rainfall.%通过对中国科学院环江喀斯特农业生态系统观测研究站所在区域的泉水和溪流在降雨对的连续采集,发现二者的水亿学特征对降雨的响应较快,但交化却不同,降雨时泉水的pH值在降雨时降低,电导率和主要离子浓度升高,SI降低,pCO2升高,而溪流的电导率和主要离子浓度降低,碳酸盐矿物饱和指数(SI)降低,水中二氧化碳分压(pCO2)降低.降雨时泉水和溪流的溶质输移速率明显增加,但没有表现出在连续降雨中因为降雨强度大输移速率就高的现象,从而推断,除了雨水的稀释作用和"土壤CO2效应"外,土壤包气带的"前水"以及主壤中可交换态高子也影响了降雨时峰丛洼地水体中溶质的运移.

    2007-07-01

    Full Text Available Abstract Background Although economic reforms have brought significant benefits, including improved health care to many Chinese people, accessibility to improved care has not been distributed evenly throughout Chinese society. Also, the effects of the uneven distribution of improved healthcare are not clearly understood. Evidence suggests that mortality is an indicator for evaluating accessibility to improved health care services. We constructed spatially smoothed risk maps for gender-specific adult mortality in an area of southern China comprising both urban and rural areas and identified ecological factors of gender-specific mortality across societies. Results The study analyzed the data of the Hechi Prefecture in southern in China. An average of 124,204 people lived in the area during the study period (2002–2004. Individual level data for 2002–2004 were grouped using identical rectangular cells (regular lattice of 0.25 km2. Poisson regression was fitted to the group level data to identify gender-specific ecological factors of adult (ages 15– Conclusion We found a disparity in mortality rates between rural and urban areas in the study area in southern China, especially for adult men. There were also differences in mortality rates between poorer and wealthy populations in both rural and urban areas, which may in part reflect differences in health care quality. Spatial influences upon adult male versus adult female mortality difference underscore the need for more research on gender-related influences on adult mortality in China.

    Data on the diet were collected from one group of Francois' langurs(Trachypithecus francoisi) between October 2005 and July 2006 at Nonggang Nature Resereve, Guangxi province, using instantaneous scan sampling. To explore the influence of water content in food on langur's food choice, water contents of the food species were measured, and the relationship between water contents of the food species and their consumption were analyzed. The results indicated that there was significant variation in the water contents of different plant parts eaten by langurs. Immature leaves had the largest value of water content,which accounted for 71. 52% ,followed by mature leaves for 66. 25% ,and fruits had the lowest value 63. 42%. The monthly mean water content in plant food showed significant variation, ranging from 61. 59% to 72. 59%. However, there was no significant difference in the mean water content in plant food according to season. The relationships between the monthly feeding time for leaves of different plant species and their corresponding water content were tested,and significant correlations in November and December were found. This indicated that water content of the food may be one of the factors influencing the food choice of the Francois' langur in Karst habitat,especially in the dry season.%2005年10月-2006年7月,对弄岗国家级自然保护区的一群黑叶猴Trachypithecus francoisi进行观察,采用瞬时扫描取样法收集有关觅食行为的数据,通过与采食植物水分含量的比较,探讨影响黑叶猴食物选择的因素.结果表明:黑叶猴采食植物不同部位的平均水分含量存在明显差异:嫩叶的水分含量最高,为71.52%;其次是成熟叶,为66.25%;果实的水分含量最低,为63.42%.虽然每个月采食植物的平均水分含量存在显著差异(61.59%~72.59%),但从整体来看,旱季和雨季所采食植物的平均水分含量未表现出显著差异.各月份黑叶猴对不同植物树叶

    Three isolates of H9N2 Avian Influenza viruses (AIV) were isolated from chickens in Guangxi province. Eight pairs of specific primers were designed and synthesized according to the sequences of H9N2 at GenBank. phylogenetic analysis showed a high degree of homology between the Guangxi isolates and isolates from Guangdong and Jiangsu provinces, suggesting that the Guangxi isolates originated from the same source. However, the eight genes of the three isolates from Guangxi were not in the same sublineages in their respective phylogenetic trees, which suggests that they were products of natural reassortment between H9N2 avian influenza viruses from different sublineages. The 9 nucleotides ACAGAGATA which encode amino acids T, G, I were absent between nucleotide 205 and 214 in the open reading frame of the NA gene in the Guangxi isolates. AIV strains that infect human have, in their HA proteins, leucine at position 226. The analysis of deduced amino acid sequence of HA proteins showed that position 226 of these isolates contained glycine instead of leucine, suggesting that these three isolates differ from H9N2 AIV strains isolated from human infections.

  12. A Mediterranean-style model for early Neoproterozoic amalgamation of South China

    Science.gov (United States)

    Zhang, Kai-Jun

    2017-04-01

    A Mediterranean-style model is proposed for early Neoproterozoic amalgamation of South China, based on recognition of the Guangxi promontory on the southeastern margin of the Yangtze craton through a synthesis of geologic, geophysical and chronological data. The model suggests that, while the Guangxi promontory collided with the overriding Cathaysia terrane along the Yunkai orogeny during the earliest Neoproterozoic, the convergence between the Yangtze craton and the Cathaysia terrane paused or slowed down, which triggered the upper Rhine Graben-style Kangdian impact rift along the western Yangtze margin and resulted in roll-back of the oceanic slab trapped in the embayments and sequential formation of backarc rifts in the Cathaysia margin during the early Neoproterozoic. This model predicts a complex diachronous Yangtze-Cathaysia collision history, first at the Guangxi promontory at ∼1000 Ma and finally at the Guizhou reentrant at ∼830 Ma.

    The Caiziyan section was located in a platform margin zone, with relatively abundant benthic and common-rare pelagic fossils, which may be regarded as a quite suitable reference section for stratigraphic correlation and division.On the basis of lithofacies and biofacies characteristics, sea-level change history is reconstructed for the interval from the Givetian to the Early Frasnian times.The Early Givetian Donggangling Formation of the study area may represent deposits under a persistent transgressive phase, probably with a slight sea-level fall at the end of the Lower varcus Zone.The lower part of the "Gubi" Formation is complex in lithology, probably resulting from extensive sea-level changes, including a significant transgressive event at the initial period of the Lower hermanni-cristatus Zone and the long-recognized mid-Givetian regression, whose timing has been precisely determined to be the Upper varcus Zone for the first time.The Late Givetian deposits host abundant tabulate corals and reef-associated bioclasts, including stromatoporoids, crinoid stemsetc., implying that the study area was probably located on the upper slope in front of a reef complex.The upper part of the "Gubi" Formation(conodont falsiovalis to lower transitans zones)is characterized by alternating medium-thin and thick bedded limestones(mainly with bioclasts of level-bottom organisms), which indicates a change from fore-reef to fore-shoal environments, probably with little overall sea-level change across the Middle-Upper Devonian boundary.The Rongxian Formation(basal part)is characterized by grayish to gray-white thin-bedded to massive limestones, which may represent a significant sea-level rise in the Middle transitans Zone in South China.The finely-medium crystalline dolostone layer at Caiziyan is within the Upper varcus Zone, with normal marine fossils including corals and conodonts.The proposed interpretation for this dolostone layer is that a substantial sea-level fall event

    Global change is a modern frontier project of earth science. Inorder to predict future climate change and well understand the dynamic process of earth evolution, the high-resolution climate change history of the last two glaciations must be studied and reconstructed. On the basis of sedimentation investigation of several large stalagmites, the high-resolution record of climate change since 160 000a B.P. in Guangxi and Guizhou provinces have been studied using carbon and oxygen stable isotope, αU-series, and TIMS U-series.The records of the climate change from stalagmites since 160 000a B.P. can be correlated with the 1 to 6 stages of that from the ocean. The time of the beginning and ending points of the last glaciation were estimated as(130.1 ±1.0) ka B.P. and (11.2±0.1) ka B.P. The accuracy from the stalagmite record is much higher than that from other record. The results indicates the epochs of Heinrich climate oscillation from stalagmite are H1 14~15 ka B.P., H2 21~23 ka B.P., H3 25~27 ka B.P. and H4 41~42 ka B.P. Furthermore, there was a large cold-event at 35~37 ka B.P. Therefore, the record of last glaciation from stalagmite may well correlate with the record from Greenland ice core.Regarding the existance epochs lagging or surpassing for long-term climate cycle to short-term abrupt climate event, perhaps, these were errors from different test-methods and test-objects (including test-error). If there would be more evidences, the epochs of some climate abrupt events in the global change could be confirmed to be in the same time. The dynamic mechanism of the short-term abrupt event might attribute to the astronomical factors as long-term climate cycle. However, the astronomical factors, which influenced the short-term abrupt climate event, cannot be recognized at present.%全球变化研究是当今地球科学最前沿的课题。要了解地球系统长期演变的动力过程,预测未来气候变化,就必须首先研究和重建最后2

    One of the most hotly debated and frontal issues in paleoanthropology focuses on the origins of modern humans.Recently,an incomplete hominin mandible with a distinctly weaker mental protuberance than modern human and a great variety of coexisting fossil mammals were unearthed from the Homo sapiens Cave of Mulan Mountain,Chongzuo,Guangxi.The mammalian fauna from the Homo sapiens Cave characterized by the combination of Elephas kiangnanensis,first occurring Elephas maixmus,and Megatapirus augustus,and strikingly different from the Early Pleistocene Gigantopithecus fauna and the Middle Pleistocene Ailuropoda-Stogodon fauna of South China could be regarded as an early representive of the typical Asian elephant fauna.Faunal analysis,biostratigraphic correlation,and,most importantly,U-series dating all consistently support an estimate of ca.110 ka for the age of the fossil Homo sapiens and coexisting mammalian fauna,that is,the early Late Pleistocene.The fauna is mainly made up of tropical-subtropical elements,but grassland elements have a much greater variety than forest elements,which probably indicates a drier climate at that time.This discovery of early Homo sapiens at the Mulan Mountain will play a significant role in the study of the origin and its environmental background of modern humans.

    Taking the soils developed on limestone and sandstone and with typical land use patterns in Karst region of Northwest Guangxi as test objects, this paper studied their soil fertility under effects of parent rock and land use pattern. A total of eleven soil fertility variables were selected for factor analysis, and the component score for each sampling site was assessed by using principal component analysis (PCA) sequencing and clustering diagram. The factor analysis indicated that the eleven variables could be reduced to four components, i.e., overall soil fertility, soil pH and total phosphorus, soil available phosphorus, and soil total potassium. The PCA sequencing and clustering analysis showed that the overall soil fertility was mainly affected by land use pattern, being the highest in abandoned farmland. Soil pH and total phosphorus content were mainly affected by parent rock. The pH value and total phosphorus content in the red soil developed on sandstone were much lower than those in the calcareous soil developed on limestone. Soil available phosphorus and total potassium contents were significantly affected by fertilization. The available phosphorus and total potassium contents in Karst calcareous soil and red soil were lower than the average level of China soils. Therefore, the Karst calcareous soil should be fertilized with ammonium nitrogen fertilizer to improve its phosphorus availability, while the Karst red soil should be amended with lime to increase its available phosphorus content. In addition, potassium fertilizer should be applied to the two soil types to improve their soil fertility.

    [Objective]A comprehensive survey was carried out to investigate the adverse effects of the severe frost and long durational cold weather from 16 December 2010 to January 2011 on sugarcane production in Guangxi. [Method]General investigation, statistical data collection and field investigation were combined for the survey which covered the sugarcane growing areas in Laibin, Liuzhou and Hechi cities where are located in the central and northwestern Guangxi. [Result]The statistical area from 1 1 counties investigated showed that about 203.25 thousand hectares(kha) of sugarcane crops were injured or damaged, and 97.43 kha of the crops were seriously damaged, accounting for 70.2% and 33.6% of the total sugarcane growing area(289.65 kha), respectively, and mainly in Liucheng, Rong'an, Rongshui, Loucheng, Wuxuan and Xiangzhou counties, and Xingbin district. The adverse effects on sugarcane varieties ROC22 and Taiyou were most serious,and the crops were deadly damaged in most areas, especially ROC22. For the damaged plants, the leaves were dried up and curled over, and the growing points and buds were destroyed, and the longitudinal section of the cane tissue looked waterlogged with liquor smell. Compared to ROC22 and/or Taiyou, however, the injury or damage was much lighter for the sugarcane varieties GT21, GT28 (GTCP00-122), GT29, GT30, GF98-296, GT97-69, GT02-208, GT02-901, GT02-467, etc,, indicating much stronger cold resistance. [Conclusion]The cold resistant sugarcane varieties such as GT21, GT28, GT02-208,GT02-901, etc., should be extended to replace the cold sensitive variety ROC22 in the central and northwestern Guangxi sugarcane growing areas. Comprehensive warming measures such as plastic film coverage, trash coverage, application of organic manures and vinasse are suggested. Priority on harvesting the deadly damaged cane crops and milling the canes as quickly as possible is strongly recommended to minimize the loss caused by the frost and chilling damage

    This study is based on the theories of terrestrial exploration risk in the Beibu Gulf Economic Zone in the Guangxi Zhuang Autonomous Region. Using ArcGIS and modelling methods, the spatial distributions of resources and environmental carrying capacity, terrestrial exploration dynamics, and terrestrial exploration potential are studied and evaluated in an integrated way. The results of the study are as follows: Mashan county, Longan county, Luchuan county, et al. have some low-risk land that can be explored, and infrastructure investment should be increased in these locations. Whereas, low-risk terrestrial development is possible in Qinzhou city, Heng county, Longan county, et al. and should be carried out in a planned and gradual fashion. The medium risk regions are distributed all over the region, but are concentrated in the city area of Nanning. However, the middle and north parts of Yulin city, the south part of Chongzuo city, Qinnan district, et al. are also in the same category and priority can be given to improve the quality and efficiency of these regions. The high risk regions, mainly distribute in the Liangqin district, Yining district, Binyang county, et al. This region should focus on the development principles of priority protection, appropriate development, and point-like development. Whereas, the extremely-high-risk areas, of which more than 60% are in Tiandeng county, Daxin county, Shanglin county, et al., are unsuitable for further development. The three-dimensional risk matrix method can make up for the deficiencies of other methods and has broad prospects in regional terrestrial development risk assessment.

    Bauxite deposits in China,rangin in age from Late Paleozoic to Cenozoic ,are distributed mainly in Shanxi,Shandong Henan,Guizhou,Guangxi and Yunnan.Based on stratigraphic relations they can be clas-sified as 6 types:inter-system marine,inter-system continental,intra-system marine,intra-system continent-tal,weathering lateritic and weathering accumulation types.But in terms of depositional environments,only four types are distinguished,I.e.the marine deposits,continental deposits,lateritic deposits and weath-ering-accumulation deposits.These deposits have been formed in two steps:firstly,the depression of paraplatform or front basin margins in paleocontinents and secondly,the development of littoral-lagoons on the eroded surface of karstified carbonate bedrocks.The aluminum may have been derived from the carbonate rocks with which the ores are associated,or from adjacent aluminosilicate rocks.

    Using 36 SSR markers and 889 accessions of common wild rice in China, the genetic diversity and the divergence among different geographical populations are investigated. Guangdong Province has the largest number of alleles, which account for 84% of the total alleles detected in the study, followed by Guangxi Province. The Nei's gone diversity indices, from high to low, are in the sequence of Hainan, Guangdong, Guangxi, Fujian, Hunan, Jiangxi, and Yunnan provinces. Two genetic diversity centers of Chinese common wild rice are detected on the basis of geographic analysis, i.e., the region covering Boluo, Zijin, Lufeng, Haifeng, Huidong and Huiyang counties of Guangdong Province and the region covering Yongning, Longan, Laibin and Guigang counties of Guangxi Province. The common wild rice in Yunnan, Hunan, Jiangxi, and Fujian provinces are diverged into respectively independent popula-tions with relatively large genetic distances, whereas, those in Hainan, Guangdong and Guangxi prov-inces have relatively low genetic divergence. Under the condition of geographic separation, natural selection is considered as one of the primary forces contributing to the divergence of common wild rice in China.

    广西东南部罗容杂岩体由辉长岩-闪长岩-二长岩-正长岩组成,马山由碱性辉长岩-正长岩-花岗闪长岩-花岗岩组成。它们富K、富大离子亲石元素(LIL),无Nb、Ta负异常等特征表明它们是形成于板内环境的钾玄质侵入岩。罗容杂岩体的各种岩石和马山的基性岩的εNd(T)高,为+1.5到+3.3,它们是交代地幔部分熔融产生的岩浆在地壳深部分异的产物。马山的花岗岩的εNd(T)稍低,为-0.6,此岩石单元是由幔源岩浆加热地壳使之熔融的壳源岩浆形成的,并伴有与幔源岩浆的混合或交换。此二杂岩体形成于拉张构造环境。地幔物质上涌导致了中生代华南地壳张裂以及华南大规模花岗岩和相关矿床的形成。%Luorong complex is composed of gabbro, diorite, monzonite and syenite, and Mashan alkaline gabbro, syenite, granodiorite and granite. They are enriched in K and LIL elements with no negative anomaly in Nb and Ta. These characteristics suggest that they belong to shoshonitic series formed in intraplate environment. All rock types in the Luorong and mafic units in the Mashan complex show high εNd(T) ranging from +1.5 to +3.3, suggesting that they were formed by fractionation of magma generated by partial melting of a metasomatized mantle in the deep crustal level. However, granite of the Mashan gives slightly lower εNd(T) -0.6, that suggests that it was formed by melting of the crust heated by the upwelling mafic magma. The near zero εNd(T) suggests an involvement of the mantle-derived component by mixing or isotope exchange. The two complexes were formed in an extensional tectonic environment. The upwelling of the mantle was responsible for the extension of the crust of southeastern China, the formation of the extensive granitic magmatism and related ore deposits during the Mesozoic era.

    Mining activities are among the major culprits of the wide occurrences of soil and water pollution by PAHs in coal district, which have resulted in ecological fragilities and health risk for local residents. Sixteen PAHs in multimedia environment from the Heshan coal district of Guangxi, South China, were measured, aiming to investigate the contamination level, distribution and possible sources and to estimate the potential health risks of PAHs. The average concentrations of 16 PAHs in the coal, coal gangue, soil, surface water and groundwater were 5114.56, 4551.10, 1280.12 ng g(-1), 426.98 and 381.20 ng L(-1), respectively. Additionally, higher soil and water PAH concentrations were detected in the vicinities of coal or coal gangue dump. Composition analysis, isomeric ratio, Pearson correlation analysis and principal component analysis were performed to diagnose the potential sources of PAHs in different environmental matrices, suggesting the dominant inputs of PAHs from coal/coal combustion and coal gangue in the soil and water. Soil and water guidelines and the incremental lifetime risk (ICLR) were used to assess the health risk, showing that soil and water were heavily contaminated by PAHs, and mean ICLRcoal/coal-gangue and mean ICLRsoil were both significantly higher than the acceptable levels (1 × 10(-4)), posing high potential carcinogenic risk to residents, especially coal workers. This study highlights the environmental pollution problems and public health concerns of coal mining, particularly the potential occupational health hazards of coal miners exposed in Heshan.

  17. Thinking on Promoting International Trade Competitive Advantage of Agricultural Products in Guangxi Based on CAFTA Framework

    Institute of Scientific and Technical Information of China (English)

    2011-01-01

    This paper analyzes the status quo and the existing problems of international trade development of agricultural products in Guangxi based on CAFTA framework as follows: the international trade of agricultural products in Guangxi shows a trend of rapid growth, but the structure of export products is simple; the distribution of export market is irrational; the export goods are mainly the resources-intensive goods and labor-intensive goods, with low added value of goods; the brand of agricultural products lacks strong overall international competitiveness. In the context of CAFTA framework, in order to foster the international trade competitive advantage of agricultural products in Guangxi, corresponding suggestions are put forward as follows: the structure of export market should change from the current simple status to diversified trend; the structure of export goods should gradually change from the current factor endowment to the orientation of international market demand; the agricultural production should change from the traditional agricultural products to advantageous complementary characteristic agricultural products; the trade structure should change from the land-intensive agricultural products to labor-intensive and technology-intensive agricultural products; the structure of merchandise trade should change from low-price vicious competition to high added-value competition; the governmental function should change from traditional one-way-direction-oriented function to modern integrated-service-and-supervision-oriented function that meets the requirements of export.

    Intimate partner violence is prevalent among female sex workers (FSWs) in China, and it is significantly associated with mental health problems among FSWs. However, limited studies have explored the mechanisms/process by which violence affects mental health. The purpose of this study was to explore the relationships among partner violence, internalized stigma, and mental health problems among FSWs. Data were collected using a self-administered cross-sectional survey administered to 1,022 FSWs in the Guangxi Zhuang Autonomous Region (Guangxi), China during 2008-2009. We used structural equation modeling to test the hypothesized relationships. Results indicated that violence perpetrated by either stable sexual partners or clients was directly and positively associated with mental health problems. Violence also had an indirect relation to mental health problems through stigma. Results highlight the need for interventions on counseling and care for FSWs who have experienced violence and for interventions to increase FSWs' coping skills and empowerment strategies.

A total of 18 seagrass species belonging to 8 genera are distributed in nine provinces and regions in China (including Hong Kong and Taiwan), as well as the Xisha and Nansha Archipelagos. They can be divided into two groups: a North China Group and a South China Group. Based on the seagrass distribution, the Chinese mainland coast can be divided into three sections: North China Seagrass Coast, Middle China Seagrass Coast, and South China Seagrass Coast. Ecological studies include research on seagrass communities, nutrient cycling in seagrass ecosystems, genetic diversity, pollution ecology and research in the key regions of Shandong, Guangdong, Guangxi, and Hainan. Seagrass species and their locations, community structure, ecological evaluation, epiphytes, ecological functions and threats in the key regions are also summarized. Other studies have focused on remote sensing of seagrass, threatened seagrass species of China, and pollen morphology of Halophila ovalis.

    The five tombs at Hepu Jiuzhiling are medium or small in size and “中”- or “凸”-shaped in plan. They are built of bricks except for a brick-and-timber grave. The objects they yielded include pottery, bronzes, irons and talcum articles, as well as jade, gold, silver, crystal, agate, amber and glassornaments. With these grave goods definite in date, the tombs help to make up gaps in the knowledge of the chronology and typology of Han burials in Guangdong and Guangxi. Meanwhile, they undoubtedly much contribute to studying the periodization of Eastern Han graves and the history of the region south of the Five Ridges. Referring to previously obtained research results, the plenty of gold, glass, agate,crystal and amber ornaments unearthed from the tombs must largely be imported goods. This has im-portant value to the study of Han period Hepu Port, the Sea Silk Road, and the overseas trade of South China.

    Han is the largest group and Zhuang is the largest minority among the 56 ethnic groups in China. Geographically and linguistically, Zhuang can be classified into 43 ethnic subgroups, in which Hei Yi Zhuang is proved to be the most conservative subgroup. Little is known about the relationship between alcohol consumption and blood pressure levels in this population. Therefore, the present study was undertaken to compare the effects of alcohol consumption and other lifestyle behaviors on blood pressure levels for the middle-aged and elderly in the Guangxi Hei Yi Zhuang and Han populations. A total of 657 subjects of Hei Yi Zhuang aged 40 and older were surveyed by a stratified randomized cluster sampling. Information on demography, diet, and other lifestyle factors was collected by standard questionnaires. Anthropometric parameters and serum lipid levels were also obtained in all subjects. The results were compared with those in 520 participants of Han Chinese from the same region. The levels of systolic blood pressure and pulse pressure in Hei Yi Zhuang were higher than those in Han (P sodium intake, educational level, physical activity, and even genetic factors.

    Full Text Available Abstract Background The association of rs1044925 polymorphism in the acyl-CoA:cholesterol acyltransferase-1 (ACAT-1 gene and serum lipid profiles is not well known in different ethnic groups. Bai Ku Yao is a special subgroup of the Yao minority in China. The present study was carried out to clarify the association of rs1044925 polymorphism in the ACAT-1 gene and several environmental factors with serum lipid levels in the Guangxi Bai Ku Yao and Han populations. Methods A total of 626 subjects of Bai Ku Yao and 624 participants of Han Chinese were randomly selected from our previous stratified randomized cluster samples. Genotyping of rs1044925 polymorphism in the ACAT-1 gene was performed by polymerase chain reaction and restriction fragment length polymorphism combined with gel electrophoresis, and then confirmed by direct sequencing. Results The levels of serum total cholesterol (TC, high-density lipoprotein cholesterol (HDL-C, apolipoprotein (Apo AI and ApoB were lower in Bai Ku Yao than in Han (P P P P P P Conclusions These results suggest that the polymorphism of rs1044925 in the ACAT-1 gene is mainly associated with female serum TC, LDL-C and ApoB levels in the Bai Ku Yao population. The C allele carriers had lower serum TC, LDL-C and ApoB levels than the C allele noncarriers.

    Taking provinces as study cases, 15 comprehensive factors, involving natural geography,agricultural production, economic and social information, were formulated to evaluate the agricultural environment in western China by factor analysis method. The results showed that comprehensive scores were distinct among different cases. The score of Sichuan was the highest, that of Chongqing second and that of Guangxi the third.Qinghai got the lowest score, ranking the twelfth. The general environment quality was better in moist southern regions than that in frigid northern regions in the provinces of western China. Therefore, the appropriate eco-environmental construction measures at provincial level should be proposed to increase vegetation coverage, control water and soil loss, and prevent desertification and wind erosion. To develop eco-agriculture is an inevitable selection for environment construction and improvement in western China.

    Full Text Available HIV-1 prevalence in Guangxi, China, has been growing since 1996, when the first case was reported. Over half of HIV-1 positive patients in Guangxi Province were injecting drug users (IDUs, possibly because of the province's location near drug-trafficking routes. Since a phase II HIV vaccine trial is ongoing there, a current characterization of the subtypes of HIV-1 among IDUs in Guangxi would provide critical information for future HIV vaccine trials, as well as further control and prevention of HIV-1 transmission. Thus, we conducted a molecular epidemiological investigation of HIV-1 samples from 2008-2010 among IDUs in multiple cities in Guangxi Province. Our results, based on the gag/pol fragment, indicated a very high proportion (78.47% of HIV-1 CRF08_BC recombinants, some CRF01_AE (15.38% recombinants, and a low proportion of CRF07_BC (6.15% recombinants among the IDUs. The high proportion of CRF08 HIV-1 strains among recent IDUs matches the vaccine candidate constructs. However, future vaccine development should also incorporate CRF01-targeted vaccine candidates. Distinct Env sequence evolution patterns were observed for CRF08_BC and CRF01_AE, indicating that different local selection pressures have been exerted on these two HIV-1 subtypes. Unique drug-resistant mutations were also detected, and our data indicate that HIV treatment programs should consider pre-existing drug-resistant mutations.

    Legumes, with a strong resistance to the adverse environmental conditions, are pioneer plants in degraded habitats, and play an important role in ecosystem restoration. In this study, the nodulation characteristics of 24 legumes were surveyed in the Karst area of Northwest Guangxi. A total of 39 nodule samples were collected from 15 legumes, the DNA was extracted and the 16S rDNA and nifH gene were amplified. A phylogenetic tree was then constructed to analyze the genetic diversity of rhizobia. The results showed that 15 legumes were nodulated, of which 14 belonged to the Papilionoideae, one to the Mimosaceae, and none to the Caesalpinoideae. No nodules were found on some legumes that were reported as nodulated, which might result from soil water stress in Karst. BLAST result and phylogenetic analyse indicated that most of the legumes were associated with rhizobia that belonged to the genus Bradyrhizobium, with the exception of two samples from Callerya nitida that were associated with the genus Mesorhizobium. In the phylogenetic tree, the sequences obtained from the same plot or the sequences from the same host species clustered together in most cases. This finding suggested that host selection and the ecological environment are the major factors that influence the genotype of rhizobia.

    2011-01-01

    Guangxi Beibu Gulf Economic Zone has taken the initiative to explore how to promote public administration of interregional local governments and achieved some success in recent years. However, there are still many problems as follows: the cooperation never goes deep;the cooperative governance is devoid of necessary system guarantee and information exchange and share platform. We analyse the status quo of cooperation in regional intergovernmental public administration as follows: it integrates the hierarchy power of government; it sponsors the forum for strengthening public administration and deepening cooperation in Beibu Gulf Economic Zone; it accelerates regional transportation system building; it sets up public administration institution; it quickens the pace of innovation of management and system in Beibu Gulf Economic Zone. Finally we put forward the path to construction of regional government cooperative governance so as to promote sustainable regional development as follows: construct the composite regional administrative cooperative governance model; construct the regional administrative network organization governance model; construct regional administrative special-project-based intergovernmental cooperative governance model; construct long-term flexible regional administrative cooperative mechanism.

    Two ancient tombs considered belonging to the Han Dynasty (206 BC to AD 220), were excavated in Hepu, Guangxi Zhuang Autonomous Region, China. According to the style of cultural relics, some excavated artifacts did not come from the region. If the age of the tombs can be confirmed as belonging to the Han Dynasty, the exotic artifacts present significant evidence to suggest that that Hepu is one of the oldest seaports on China's ancient maritime trading route. Two wood samples were sent for {sup 14}C dating at CIRCE, Italy. The results of these measurements are presented and the related chronology is discussed. Considering the previous results from a pottery workshop and an excavated sea wharf, the interpretation of Hepu as one of the oldest seaports in ancient China and the important role it played is presented.

    Rapid changes in China over the past two decades have led to significant problems associated with population migration and changing social attitudes, including a growing sex industry and concurrent increases in STIs and HIV. This article reports results of an exploratory study of microbicide acceptability and readiness and current HIV prevention efforts among female sex workers in two rural and one urban town in Hainan and Guangxi Provinces in southern China. The study focused on these women's knowledge and cultural understandings of options for protecting themselves from exposure to STIs and HIV, and the potential viability and acceptability of woman-initiated prevention methods. We report on ethnographic elicitation interviews conducted with women working within informal sex-work establishments (hotels, massage and beauty parlors, roadside restaurants, boarding houses). We discuss implications of these findings for further promotion of woman-initiated prevention methods such as microbicides and female condoms among female sex workers in China.

    Approximately two billion people drink unsafe water. Boiling is the most commonly used household water treatment (HWT) method globally and in China. HWT can make water safer, but sustained adoption is rare and bottled water consumption is growing. To successfully promote HWT, an understanding of associated socioeconomic factors is critical. We collected survey data and water samples from 450 rural households in Guangxi Province, China. Covariates were grouped into blocks to hierarchically construct modified Poisson models and estimate risk ratios (RR) associated with boiling methods, bottled water, and untreated water. Female-headed households were most likely to boil (RR = 1.36, p boiled. Our findings show that boiling is not an undifferentiated practice, but one with different methods of varying effectiveness, environmental impact, and adoption across socioeconomic strata. Our results can inform programs to promote safer and more efficient boiling using electric kettles, and suggest that if rural China's economy continues to grow then bottled water use will increase.

    Full Text Available BACKGROUND: Investigation of the genetic diversity of Mycobacterium tuberculosis in China has shown that Beijing genotype strains play a dominant role in the tuberculosis (TB epidemic. In order to examine the strain diversity in the whole country, and to study the evolutionary development of Beijing strains, we sought to genotype a large collection of isolates using different methods. METHODOLOGY/PRINCIPAL FINDINGS: We applied a 15-loci VNTR typing analysis on 1,586 isolates from the Beijing municipality and 12 Chinese provinces or autonomous regions. The data was compared to that of 900 isolates from various other worldwide geographic regions outside of China. A total of 1,162/1,586 (73.2% of the isolates, distributed into 472 VNTR types, were found to belong to the Beijing genotype family and this represented 56 to 94% of the isolates in each of the localizations. VNTR typing revealed that the majority of the non-Beijing isolates fall into two genotype families, which represented 17% of the total number of isolates, and seem largely restricted to China. A small number of East African Indian genotype strains was also observed in this collection. Ancient Beijing strains with an intact region of difference (RD 181, as well as strains presumably resembling ancestors of the whole Beijing genotype family, were mainly found in the Guangxi autonomous region. CONCLUSIONS/SIGNIFICANCE: This is the largest M. tuberculosis VNTR-based genotyping study performed in China to date. The high percentage of Beijing isolates in the whole country and the presence in the South of strains representing early branching points may be an indication that the Beijing lineage originated from China, probably in the Guangxi region. Two modern lineages are shown here to represent the majority of non-Beijing Chinese isolates. The observed geographic distribution of the different lineages within China suggests that natural frontiers are major factors in their diffusion.

    The burrowing nematode(Radopholus similis)is one of the main quarantine pests in China,and the risk of invasion posed by this nematode is becoming more and more serious with regard to the international trade being intensified day by day.It is urgent to analyse the potential geographic distribution of R.similis in China.Genetic algorithm for rule-set prediction modeling system(GARP)and maximum entropy(MAXENT),the two niche models which have been widely used to predict the potential geographic distribution of alien species,were used to predict the distribution of R.similis in China.We also presented a model comparison of the results by both threshold-dependent and threshold-independent evaluations.It has been shown that the two niche models could be used to predict the potential distribution of R.similis reliably.The potential distribution of R.similis should be constricted within the south of China,such as Hainan,Guangdong,Guangxi,Fujian,Yunnan provinces,and Taiwan of China.The MAXENT gives a better prediction than that of GARP.R.similis can be introduced to China by flowers and nursery stock's international shipping.The predicted results indicate that R.similis can occur in south coastal area of China and Yunnan Province,which are the main flower and nursery stock's import-export areas in China.Consequently,a strong quarantine program is needed at the ports of such areas to prevent the pest from being introduced to China.

    To learn and implement the report of the 18th National Congress of the Communist Party of China, Guangxi regards “accepting industrial transfer” as one of the important content of seizing strategic opportunities, in the discourses of “seizing strategic opportunities”. With the adjustment of industrial structure at home and abroad, especial y recombination of domestic and overseas industrial layout in post-crisis era, mid and low-end industries in developed countries transfer to developing countries, conventional industries in domestic coastal developed areas transfer to midwest area. Processing trade industry is conventional industry in Chinese coastal developed areas. Processing trade gradient transfer is an important strategic measure for promoting balanced development among regions and closing the gap between the eastern and western areas. Based on the influence of processing trade by the financial crisis and the existing problems, the thoughts of accepting processing trade gradient transfer for Guangxi is analyzed.%在学习贯彻党的十八大报告,有关把握战略机遇期的论述中,广西将承接产业转移,视为把握战略机遇期的重要内容之一。随着国内外产业结构调整,特别是“后危机时代”国内外产业布局的重新组合,无疑会推动发达国家的中低端产业向发展中国家转移、国内沿海发达地区的传统产业向中西部地区转移。加工贸易制造业是我国沿海发达地区的传统产业,开展加工贸易梯度转移是国家推动区域协调发展、缩小东中西部差距的一项重要战略举措。基于金融危机对广西加工贸易的影响及存在的问题,本文提出在后危机时代广西承接加工贸易梯度转移的思路。

    Institution-based childbirth, with the ultimate goal of universal access to skilled birth attendance (SBA), has been selected as a key strategy to reduce the maternal mortality rate in many developing countries. However, the question of how to engage traditional birth attendants (TBAs) in the advocacy campaign for SBA poses a number of challenges. This paper aims to demonstrate how TBAs in rural regions of China have been integrated into the health system under a policy of institutional delivery. Research was conducted through literature and document reviews and individual in-depth interviews with stakeholders of the safe motherhood program in rural Guangxi Zhuang Autonomous Region, China. A total of 33 individual interviews were conducted with regional and local politicians, policy makers, health managers, health providers, civil society members, village cadres for women affairs, former TBAs, village maternal health workers, mothers and their mother-in-laws. Since 1998, TBA's traditional role of providing in-home care during childbirth has been restructured and their social role has been strengthened in rural Guangxi. TBAs were redesigned to function as the linkage between women and the health system. A new policy in 1999 shifted the role of TBAs to village maternal health workers whose responsibilities were mainly to promote perinatal care and institution-based delivery of pregnant women. This successful transformation involved engaging with government and other actors, training TBAs for their new role, and providing incentives and sanctions for human resources management. The China experience of transforming the role of TBAs in Guangxi rural area is an example of successfully engaging TBAs in promoting institution-based childbirth.

    Most of China's 24-28 primate species are threatened with extinction. Habitat reduction and fragmentation are perhaps the greatest threats. We used published data from a conservation genetics study of 5 endangered primates in China (Rhinopithecus roxellana, R. bieti, R. brelichi, Trachypithecus francoisi, and T. leucocephalus); distribution data on these species; and the distribution, area, and location of protected areas to inform conservation strategies for these primates. All 5 species were separated into subpopulations with unique genetic components. Gene flow appeared to be strongly impeded by agricultural land, meadows used for grazing, highways, and humans dwellings. Most species declined severely or diverged concurrently as human population and crop land cover increased. Nature reserves were not evenly distributed across subpopulations with unique genetic backgrounds. Certain small subpopulations were severely fragmented and had higher extinction risk than others. Primate mobility is limited and their genetic structure is strong and susceptible to substantial loss of diversity due to local extinction. Thus, to maximize preservation of genetic diversity in all these primate species, our results suggest protection is required for all sub-populations. Key priorities for their conservation include maintaining R. roxellana in Shennongjia national reserve, subpopulations S4 and S5 of R. bieti and of R. brelichi in Fanjingshan national reserve, subpopulation CGX of T. francoisi in central Guangxi Province, and all 3 T. leucocephalus sub-populations in central Guangxi Province. © 2015 Society for Conservation Biology.

    Three Devonian reefs (bioherms) from Yunnan and Guangxi, southern China, are studied in detail.Six microfacies types are differentiated. Colonial rugose corals (Columnaria, Disphyllum and Hexagonaria) at Qujing, tabulate corals (Alveolites) with massive stromatoporoids (Actinostroma and Stromatoporella) and sponges at Panxi, and massive stromatoporoids (Actinostroma, Trupetostroma and Stromatoporella) at Yangshuo belong to the most important reef builders. All the three reefs studied clearly reveal a successive evolution history. They developed on the carbonate banks, shallow carbonate platforms and platform margins in the Late Givetian and terminated in the Frasnian due to sea-level falls related to local uplifts of platforms. This coincides with a eustatic fall of relative sea level at the Frasnian/Famennian transition.

    Apple maggot fly, Rhagoletis pomonella (Walsh) is a major pest causing considerable economic losses of fruits in North America. During the development of international trade, apple maggot fly has become a threat to Chinese agriculture. In this study, CLIMEX and ArcGIS were used to predict the potential geographical distribution of apple maggot fly in China. The parameters used in CLIMEX for apple maggot fly were derived from ecological data and the present geographical distribution of apple maggot fly in North America. Then the potential distribution map in China was presented based on the adjusted values of these parameters. The results showed that apple maggot fly has a wide potential distribution area in China; 47.5% of 748 meteorological stations presented high or medium suitability of pest establishment. These high suitable stations are mainly located in northeast, southwest and northwest of China, such as Liaoning, Shandong,Gansu and Shaanxi Provinces. These areas are also the central regions of apple, pear and peach production in China. Two hundred and twenty-five stations (30.1%) in western and southern China, such as Tibet, Qinghai, Guangdong, Guangxi, Hainan and Taiwan,were unsuitable for establishment of apple maggot fly populations. In order to prevent the introduction of apple maggot fly in China, the present plant quarantine measures should be enhanced, especially in the areas with high suitability for the presence of apple maggot fly.

    The Kuok Group, owned by Malaysian tycoon Robert Kuok, has emerged as the latest potential investor in a petrochemicals joint venture in China. The group, which has assets including the Shangri-La chain of hotels and several urea formaldehyde plants in Malaysia and Singapore, has signed a memorandum of understanding with the local authorities of Beihai, Guangxi province to study a $3-billion refinery and petrochemicals complex. Beihai, in coastal southwestern China, is near the Vietnam border. The project, understood to be in the preliminary scoping phase, would include a 100,000-bbl/day refinery and a world-scale 450,000-m.t./year cracker that would feed a 450,000-m.t./year polyethylene unit. To make the operation competitive, the group is considering building an ethylene cracker and looking for a cheap source of natural gas. It is understood that an undisclosed Western company has joined forces in the joint venture, which is not one of the 14 petrochemicals complexes currently planned in China. Kuok, who has good contacts in China and has just agreed to develop a commercial complex in Shanghai's Zhabei district, has been approached by the Beihai authorities. Beihai, an economic development zone, would like its own refinery. The closest one is in Maoming. A decision is expected by the end of then year.

    桂西南地处广西西南部与越南接壤,唐宋时期此区域还是荒蛮与朝廷流放犯人瘴气弥漫之地。经过明清“改土归流”政策的推行,中央加强了对此区域的管理;桂西南地区逐步得到开拓。经过明清时期的“改土归流”,随之清政府推行“摊丁入亩”,极大的促进了桂西南地区人口的增长与税收收入的增加,促进了当地经济发展。桂西南地区在明清之际,开始重视农田水利的开垦,并且引进新农具和新经济作物诸如“番薯、玉米、甘蔗、烟草”的种植,改善了当地经济发展模式,使桂西南地区经济得到开拓和发展。随着桂西南经济的发展,桂西南人口数量出现不断增长,人口持续不断增长也促进了桂西南文教的发展,进而体现在桂西南地区人才罕见的迅速崛起与发展壮大。随着桂西南地区经济不断的发展,大量高素质的人才不断的崛起,逐步改变桂西南地区荒蛮,使得此地瘴气逐渐消散。%Southwest Guangxi borders Vietnam. This area was still wild and filled with miasma,where the prisoners were exiled to by the court in Tang and Song dynasties. After the implementation of "Chieftainship Reform"in Ming and Qing Dynasties,the central authorities strengthened the management of this region and southwestern Guangxi gradually opened up. With the implementation of "Chieftain Reform"in Ming and Qing Dynasty, and the "Sharing Man Taxation Into Fields"policy was carried out by Qing government,the population growth was promoted and the tax revenue was increased greatly in the Southwestern Guangxi,Which promoted the local economic development. Southwestern Guangxi began to pay attention to the reclamation of farmland and development of water conservancy facilities in the Ming and Qing dynasty,and introduce new farm implements and economic crops species such as sweet potato,corn,sugar cane,tobacco to agriculture production

    The objective of this paper is to investigate the rela-tionships among rural-urban migration, rural household income and sustainable development in rural areas of China. The typical case study is done and 288 questionnaires are collected from five villages in Hebei and Guangxi provinces, China. The migration and remittance status, household income and sustainable devel-opment of rural areas are analyzed on the basis of questionnaires. Rural-urban migration is becoming a part of routine life in rural areas. And remittance is an important component in rural house-hold income. Rural-urban migration increases the arable land area per labor, which releases the tight human-land relationship in villages. In total, the migration increases the rural household in-come and accelerates the sustainable development of rural areas.

    Full Text Available Using a sample of province-level panel data, this paper investigates the Granger causality associations among economic growth (GDP, foreign direct investment (FDI and CO2 emissions in China. By applying the bootstrap Granger panel causality approach (Kónya, 2006, we consider both cross-sectional dependence and homogeneity of different regions in China. The empirical results support that the causality direction not only works in a single direction either from GDP to FDI (in Yunnan or from FDI to GDP (in Beijing, Neimenggu, Jilin, Shanxi and Gansu, but it also works in both directions (in Henan. Moreover, we document that GDP is Granger-causing CO2 emissions in Neimenggu, Hubei, Guangxi and Gansu while there is bidirectional causality between these two variables in Shanxi. In the end, we identify the unidirectional causality from FDI to CO2 emissions in Beijing, Henan, Guizhou and Shanxi, and the bidirectional causality between FDI and CO2 emissions in Neimenggu.

    The organic matter of three different chronological major carbonaceous rock gold-bearing formations of South China (Middle Proterozoic Shangqiaoshan group of northeastern Jiangxi, Lower Cambrian Shuikou group of northern Guangxi and Devonian Shetianqiao group of eastern Hunan) and related carbonaceous stratabound gold deposits such as Jinshan, Longshui and Shixia deposits, respectively, has been characterized by organic geochemical techniques. These organic geochemical results show that the average total organic carbon (TOC) content of the three chronological carbonaceous rock gold-bearing formations of South China ranges from 0.15% to 1.56%. The thermal maturity of the organic matter of host rocks in the three gold-bearing formations is high. The micro-component of the organic matter of the host rocks consists primarily of solid bitumen and graphite. The organic carbon and gold of the host rocks appear to syndeposit in situ during the formation of the gold-bearing formations. The organic carbon played

    Based on the data from 94 experiments of straw returning in Anhui, Jiangxi, Hunan, Hubei, Guangxi, Sichuan, and Chongqing, and by using mathematic modeling approach, this paper evaluated the effects of straw returning on the soil fertility and crop yield in southern China. Obvious regional differences were observed in the soil fertility index (SFI) and crop yield response. In study area, the croplands with the SFI of Grade III and Grade IV were predominant, occupying 69.1% and 21.3% of the total, respectively. Averagely, straw returning increased the SFI and crop yield by 6.8% and 4.4%, respectively, as compared with the control (no straw returning). The SFI was significantly linearly correlated with rice yield, and could well reflect the integrated soil fertility in study area. At present, straw returning with decomposing agent added is one of the most important measures to improve the integrated soil fertility in southern China, which should be widely popularized.

    China's rapid economic growth has been accompanied by increasing environmental pollution. Mangrove ecosystems are now facing greater pollution pressures due to elevated chemical discharges from various land-based sources. Data on the levels of heavy metals and organic pollutants in mangrove compartments (sediments, plants, zoobenthos, and fish) in China over the past 20 years have been summarized to evaluate the current pollution status of the mangrove ecosystem. Overall, the Pearl River and Jiulong River estuaries were severely polluted spots. Concentrations of Cu, Zn, Cd, and Pb in mangrove sediments of Guangdong, Fujian, and Hong Kong were higher than those from Guangxi and Hainan. The pollution status was closely linked to industrialization and urbanization. The highest concentrations of polycyclic aromatic hydrocarbons (PAHs) were found in mangrove sediments from Hong Kong, followed by Fujian and Guangdong. Mangrove plants tend to have low-enriched ability for heavy metals and organic pollutants. Much higher levels of Pb, Cd, and Hg were observed in mollusks.

The results show that the general level of Mytilaria laosensis natural population genetic diversity in Guangxi is high. The genetic diversity level of four populations is different largely. The level of genetic diversity of Pingxiang population in Guangxi is the highest among the four populations , and that of Napo population in Guangxi is the lowest. The analysis of genetic differentiation shows that the 82.43% of genetic variation is in population, and the others is not in population by PopGen 32. Coefficient of genetic differentiation (Gst) among four populations is 0. 175 8 and the gene flow (Nm) among Mytilaria laosensis is 2. 344 7. It shows that the level of genetic differentiation is low and gene flow is sufficient to resist the effects of genetic drift. UPGMA cluster analysis shows that four populations can be classified two kinds, and the population of Pingxiang, Debao and Jingxi in Guangxi are divided into one kind and the population of Napo in Guangxi is divided into one kind alone.

    Previously, we reported 10 PEGE types of 85 tilapia Streptococcus agalactiae (GBS), which shifted from Streptococcus iniae in China, by using PEGE method. Presently, larger and more representative tilapia GBS were isolated, for the first time in China, to characterize their serotypes and genetic diversities more precisely than had done before. 168 GBS strains were distributed in five provinces of China, in which Guangdong, Guangxi and Hainan were the major ones, holding 36.9% (62/168), 37.5% (63/168) and 19.6% (33/168), respectively. Serotypes, Ia, Ib and III, were observed in these strains and the most predominant one was Ia (95.2%), which mainly distributed in Guangdong, Guangxi and Hainan. Ia initially occurred in 2009, it shoot up to 32.1% in 2010, but decreased to 16.1% in 2011 before went up to 45.2% in 2012. Ib sporadically occurred during 2007-2011, III only occurred in 2012. 14 different PFGE types, including 4 new types (N, O, P and Q), were observed, in which B, D, F and G were the predominant types, holding 83.9% (141/168) of the total GBS strains. Ia corresponded to 11 PFGE types (A-H, N-P), in which type D predominated (51%). Ib represented 3 genotypes (I, J and Q) and III harbored only 2 genotypes (N and F). Type N and F synchronously presented in Ia and III. In summary, the genetic diversity of tilapia GBS varied by serotypes and changed with geographical locations and years. Although Ia still predominated, new rare serotype III already occurred in China.

    Phenacoccus solenopsis Tinsley (Hemiptera: Pseudococcidae) is an invasive mealybug that seriously damages cotton and other important crops. In previous studies in China, the presence of two submedian longitudinal lines of pigmented spots on the dorsum of adult females frequently has been used to identify this species. However, the present study records the occasional absence of pigmented spots in a sample from Guangxi province, China. Specimens without pigmented spots showed all the molecular and morphological characters that separate P. solenopsis from the similar species P. solani Ferris, especially the distribution of multilocular disc pores. In different geographic populations of P. solenopsis in China, mitochondrial COI and nuclear 28SrDNA genes are very similar (99.8-100%), indicating that they are conspecific. For COI, the genetic distance between P. solenopsis and P. solani is more than 3%. A map of the distribution of P. solenopsis in China is given. To help identify both pigmented and non-pigmented P. solenopsis accurately, an identification key to the 16 species of Phenacoccus found in China is provided. The key also identifies five potentially invasive Phenacoccus species not yet established in China, in case they get introduced there.

    There were a great many literature writings in Guangxi in the Qing Dynasty with talented and appreciative taste. The writings are mostly poems which are in an unbalanced state in different areas in Guangxi. Because at that time those writings were spread by means of home issuing and individual copying, most of the writings were unfortunately missing with the passage of time.%清代广西的文学著述不仅数量可观,而且质量也足可称道。著述以诗歌类数量最多,地区分布极不平衡,主要依赖于家刊私刻流传于世,大部分文学著述已在历史的风尘中湮没不存。

    These tombs are situated in the Han-tomb-protecting area within Hepu County,Guangxi. In December of 1996, in concert with a capital construction, the Guangxi Archaeological Team carried out a rescuing excavation in the cemetery and revealed 11 Han tombs. These are brick-chambered graves with a single-layer arched ceiling or a dome and a “中”,“十”-or“干”-shaped or rectangular plan,and consist of a front, a middle and a rear rooms and side ones. The funeral objects unearthed include pottery, bronze, iron and talcum articles. Among them the lotus-flower-shaped pottery vessels are unique in form and might be products of the influence of Buddhist culture from abroad. In date the tombs are of the late Eastern Han period.

    利用1960-2009年广西80个地面观测站资料,运用EOF、线性倾向估计等统计方法,分析了近50年广西霾日数的时空变化特征.结果表明:近50年广西霾日数总体呈上升趋势,与该地区人类活动和经济发展引起的污染排放增长密切相关;空间分布呈现出主要城市及其周边地区霾日多,边远地区及沿海地区霾日少的特点;广西霾天气主要发生在秋、冬季,以轻微霾(能见度为5~10 km)为主,且霾天气发生时的相对湿度8成以上介于70%~90%;除了空气污染之外,近50年风速呈下降趋势可能也导致更多的霾天气.%With the development of Guangxi economy and accelerating urbanization, human activities have discharged various pollutants into the atmosphere, which cause increasing atmospheric haze phenomenon in recent years. The toxic and harmful substances of hazes affect human health and environment a lot, becoming a new kind of severe weather. So it is very important to analyze the spatial-temporal variation characteristics of haze, which provide scientific bases for effective forecasting and controlling haze weather. Based on the data provided by 80 surface observation stations from 1960 to 2009, the haze days in Guangxi are calculated, and the characteristics of spatial-temporal variations of haze in Guangxi and its relationship with climate elements are analyzed by using EOF, linear trend estimation and other analytical methods. The average annual haze days in Guangxi are found to rise gradually over the past 50 years, which is closely related to the human activity and the increase in emissions by economic development. The haze happens more frequently in major cities and their surrounding areas than in remote areas and coastal areas. Comparing the periods of 1960-1979 and 1980-2009, and the remote areas and coastal areas, the haze days increase by different degrees in most parts of Guangxi, especially in Wuzhou, Liuzhou and other industrial

    The Gantuoyan site is the cave site nearest to the continent of Southeast Asia recorded so far in Guangxi. The prehistoric cultural deposits yielded plenty of objects and fall into two phases. Thefirst phase belongs to the late Neolithic Age and dates from about 5000BP. Its cultural relics include pottery, stone and bone artifacts. Among the prevailing pottery utensils are round-based and three-legged vessels and spindle-whorls, with bo bowls occurring frequently and jars often shaped like a cup largelywith three legs or furnished with a high neck. The vessel surface is decorated with incised design variedin form. The second phase corresponds roughly to the Shang period, dating from about 3000-2800BP.The unearthed objects include pottery articles, stone tools and bone artifacts. There prevailed ring-foot vessels and spindle whorls. The former belong to the types of jar, high-necked jar, gui-basin-shapedvessel, large-mouthed fu cauldron, outturned-rimmed fu, pot, basin and bo bowl. They are decoratedwith incised geometrical motifs, painted patterns, and incised-stamped-painted designs. Among the im portant finds are stone yue battle-axes and molds and serrated zhang tablets. The site is of great value to establishing a sequence of cultural development for prehistoric southwestern Guangxi and to researching into the relationship of the prehistoric culture in Guangxi with those in Southeast Asia.

    As a result of more and more serious energy risks, the study of national energy security zoning is not only the basic requirement of energy risk management but also the new demand of economic development for the energy industry. Firstly, this paper analyzes the basic situation of energy resources and production and consumption of pri-mary energy from 1996 to 2005 in China. Secondly, this paper founds an Energy Security Index System formed by six indices including the percentage of energy reserves, intertocal dependent degree, energy elcsticity coefficient and so on. It subsequently calculates the weight of these indices with the factor analysis rating method. Lastly, the paper evaluates and zones the abilities of energy security of 30 provinces in China with the grey cluster method. According to their security, the 30 provinces are classified into three diferent levels: high, medium, and low levels. The regions at low energy security level include Beijing, Shanghai, Zhejiang, Fujian, Guangdong, Guangxi and Hainan. They are mainly littoral and short of primary energy production while mostly dependent on other provinces. Those at medium energy security level include 15 provinces (cities or districts), such as Liaoning, Tianjin, Hebei, Shandong, Henan, Hunan and so on. These provinces are in the northeast, north, east of and central China. Those at high energy secu- rity level contain Shanxi, Inner Mongolia, Heilongiiang, Jilin, Chongqing, Sichuan, Shaanxi, Xinjiang. These prov-inces are the main primary energy production bases.

    Anthracnose, caused by the Colletotrichum species of fungi, is one of the most serious diseases affecting jute in China. The disease causes chlorotic regions with black brown sunken necrotic pits on the surfaces of stems. In late stages of disease, plants undergo defoliation, dieback and blight, which make anthracnose a major threat to jute fiber production and quality in China. In this study, 7 strains of Colletotrichum fungi were isolated from diseased jute stems from Zhejiang, Fujian, Guangxi, and Henan plantations in China. Multi-locus sequence (ACT, TUB2, CAL, GS, GAPDH and ITS) analysis coupled with morphological assessment revealed that C. fructicola, C. siamense and C. corchorum-capsularis sp. nov. were associated with jute anthracnose in southeastern China. C. fructicola and C. siamense were previously not associated with jute anthracnose. C. corchorum-capsularis is a new species formally described here. Pathogenicity tests confirmed that all species can infect jute, causing anthracnose, however the virulence of the 3 species differed. This report is the first associating these three species with jute disease worldwide and is the first description of the pathogens responsible for jute anthracnose in China.

    2015-11-01

    Full Text Available As one of the most important renewable and sustainable energy sources, the forest biomass energy resource has always been the focus of attention of scholars and policy makers. However, its potential is still uncertain in China, especially with respect to its spatial distribution. In this paper, the quantity and distribution of Chinese forest biomass energy resources are explored based mainly on forestry statistics data rather than forest resource inventory data used by most previous studies. The results show that the forest biomass energy resource in China was 169 million tons in 2010, of which wood felling and bucking residue (WFBR,wood processing residue (WPR, bamboo processing residue, fuel wood and firewood used by farmers accounted for 38%, 37%, 6%, 4% and 15%, respectively. The highest resource was located in East China, accounting for nearly 39.0% of the national amount, followed by the Southwest and South China regions, which accounted for 17.4% and 16.3%, respectively. At the provincial scale, Shandong has the highest distribution, accounting for 11.9% of total resources, followed by Guangxi and Fujian accounting for 10.3% and 10.2%, respectively. The actual wood-processing residue (AWPR estimated from the actual production of different wood products (considering the wood transferred between regions showed apparent differences from the local wood processing residue (LWPR, which assumes that no wood has been transferredbetween regions. Due to the large contribution of WPR to total forestry bioenergy resources, the estimation of AWPR will provide a more accurate evaluation of the total amount and the spatial distribution of forest biomass energy resources in China.

  12. HCV subtype characterization among injection drug users: implication for a crucial role of Zhenjiang in HCV transmission in China.

    Directory of Open Access Journals (Sweden)

    Chiyu Zhang

    Full Text Available BACKGROUND: HCV transmission is closely associated with drug-trafficking routes in China. However, the transmission route of HCV in Eastern China remains unclear. Here, we investigate the role of Zhenjiang city of Jiangsu province, an important transportation hub linking Shanghai with other regions of China, in HCV transmission. METHODOLOGY/PRINCIPAL FINDINGS: A total of 141 whole blood samples were collected from injection drug users (IDUs in Zhenjiang and then tested for HCV infection. Of them, 115 HCV positive plasmas were subjected to RNA extraction, RT-PCR amplification, and sequencing. The subtype characterization and the evolutionary origin of HCV strains circulating in Zhenjiang were determined using polygenetic or phylogeographic analyses. Seven HCV subtypes 1b, 2a, 3a, 3b, 6a, 6e and 6n were detected among Zhenjiang IDUs, showing a complex HCV epidemic. The most predominant subtypes were 3a (38% and 1b (26.8%. Among these subtypes, subtypes 3b, 6n and 6e originated from Southwestern China (i.e., Yunnan and/or Guangxi, subtypes 2a and 6a from Southern China (i.e., Guangdong, subtype 1b from Central (i.e., Henan and Northwestern (i.e., Xinjiang China, and subtype 3a from Southwestern (i.e., Yunnan and Northwestern (i.e., Xinjiang China. From Zhenjiang, subtypes 1b and 2a were further spread to Eastern (i.e., Shanghai and Northern (i.e., Beijing China, respectively. CONCLUSIONS/SIGNIFICANCE: The mixing of seven HCV subtypes in Zhenjiang from all quarters of China indicates that as an important middle station, Zhenjiang plays a crucial role in HCV transmission, just as it is important in population migration between other regions of China and Eastern China.

    Guizhou province, located between border provinces and Central province of China, plays a crucial role in the transmission of HIV-1, implying it is important to monitor the epidemic of HIV-1 in this region. Available HIV-1 infected patients' plasma (n=78) were collected from Tongren city, Eastern Guizhou. Full-length gag, partial pol and env gene sequences were amplified and analyzed using phylogenetic, recombinant and Bayesian molecular clock approaches. Phylogenetic and recombinant analyses showed that CRF01_AE predominated among injecting drug users and heterosexuals in Tongren city with 85.9% proportion, it was followed by B' (5.1%), CRF07_BC (3.8%), CRF08_BC (3.8%), and B (1.3%). Moreover, 98.5% of CRF01_AE strains belonged to the distinct lineage CRF01_AE-v previously found in Guangxi province. To infer the most probable origin of CRF01_AE-v in Guizhou province, we download all available full length of CRF01_AE gag, pol and env gene region sequences from China in Los Alamos HIV sequence database. Phylodynamic and phylogeographic analyses revealed that the expanding CRF01_AE-v epidemic in Guizhou province was the result of local epidemic driven by multiple independent introductions of CRF01_AE-v strains from Guangxi province in early 2000s. High prevalence of CRF01_AE in Guizhou province may bridge the epidemic to Central China. It provides a new insight for the understanding of HIV-1 epidemic in Guizhou province and makes the evolutionary history of CRF01_AE in China more intact. Copyright © 2014 Elsevier B.V.

    This paper studied the profile distribution characters of 137Cs and soil organic carbon (SOC) on the Karst slopes and in the fissures in typical peak-cluster depression in Northwest Guangxi, aimed to approach the applicability of 137Cs method on Karst slopes and the implication of 37Cs for the characteristics of slope soil erosion. In all test profiles, there was a significant correlation between 137Cs and SOC, indicating that both of them might have the same loss pathway. On the slopes under secondary forests, 137Cs mainly existed within the depth 0-24 cm. On the upper middle and middle slope sites, 137Cs had an exponential decrease with depth, indicating no or slight surface erosion; while on the foot slope site, the distribution pattern of 137Cs indicated severer erosion. On the slopes with cultivated lands, 137Cs distributed uniformly within the plough layer. In the upper middle and middle slopes profiles, 137Cs mainly existed in the depth around 15 cm and far less than the background value, indicating severe soil erosion; while in foot slope profiles, 137Cs was aggraded to the depth 45 cm. A discontinuous distribution of 137Cs in the profiles was detected on the foot slopes under secondary forests, on the upper middle and foot slopes of cultivated lands, and in the fissures, indicating that the soil particles on Karst slopes had a trend of losing with rainwater to the underground, but the loss quantity was negligible, compared with surface erosion.

    Phytophthora melonis is the casual agent of wax gourd and cucumber Phytophthora blight which becomes a constraint for sustainable production of the related crops. Metalaxyl is one of the principal fungicides for controlling the disease now. The objectives of the present study were: (1) to investigate the baseline sensitivity and field resistance of P. melonis to metalaxyl in South China; (2) to test the occurrence of metalaxyl-resistant mutants from metalaxyl-sensitive wild type strains exposed to the fungicide; and (3) to monitor the development of metalaxyl resistance in P. melonis population. Over 400 samples of wax gourd and cucumber Phytophthora blight were collected from Guangxi Zhuang Autonomous Region and Guangdong province during 2007-2010, and 193 strains of P. melonis were isolated and purified. The sensitivity of the isolated strains to metalaxyl was tested using mycelial growth rate method in vitro and floating-leaf-disk method in vivo, respectively. The metalaxyl-sensitive strains were induced on PDA plates containing 10 microg/mL metalaxyl. The sensitive, moderately resistant and resistant strains were recorded as 29.0% , 18.1% and 52.8%, respectively, among 193 tested strains. The frequency and level of resistance of P. melonis from Guangdong were higher than that from Guangxi. The strains from cucumber was generally more resistant to metalaxyl than those from wax gourd. The metalaxyl-resistant strains were frequently detected as predominant populations in most of the sampling sites and the highest resistance index (4226.9) was confirmed. Metalaxyl-resistant (M1r) mutants could be isolated from approximately 60% of the sensitive wild-type strains. The resistance level of the M mutants was 189-407 times higher than that of their sensitive parental strains. The EC50 values of 9 sensitive strains from a sampling site without a record of phenylamide fungicide application ranged from 0.0429 to 0.5461 microg/mL. Their mean EC50 value (0.3200 +/- 0

    2007-01-01

    The spatial heterogeneity and ecological characteristics of 74 vegetation types and the lack of vegetation type within the 9.6 million km2 of Chinese territory were studied using data from the China vegetation map. The analysis used 877 large quadrats 10 mm×10 mm (actual size 100 km×100 km), which covered about 8.77 million km2. Each large-quadrat was divided into four small 5 mm×5 mm quadrats (actual size 50 km×50 km). The frequency of occurrence of all vegetation types was recorded in each small quadrat.The survey using the Shiyomi method of vegetation analysis based on the beta-binomial distribution was adopted to describe the frequency of occurrence and spatial heterogeneity for each kind of vegetation. The weighted average heterogeneity of all the vegetation types in the landscape provides a measure of the landscape level heterogeneity which describes the spatial intricacy of the existing vegetation composition.The maximum spatial vegetation heterogeneity was 0.8620 in the frigid-temperate coniferous forest of Larix(V1), which dominates cold moist northeast China. The minimum spatial heterogeneity with a low occurrence was the Caragana tibetica in the gravel desert in the western Yellow River Hetao area. The minimum occurrence with a low spatial heterogeneity was the Monsoon rainforest on rock in Guangxi and Yunnan Provinces. The vegetation types on the Qing-Zang Plateau were found to be representative of Chinese vegetation because of the very high occurrence and spatial heterogeneity of these vegetation types. The weighted average of the heterogeneity was 0.677, while the vegetation diversity index was 3.29.

    Objective To study the contamination of total aflatoxins (AFs) in different kinds of foods including corn, peanut, rice,walnut, and pine nut in six provinces and two municipalities in China. Methods A total of 283 samples of corn, peanut, rice,walnut and pine nut were randomly collected from local markets in Fujian, Guangdong, Guangxi, Hubei, Jiangsu, and Zhejiang provinces, as well as in Shanghai and Chongqing municipalities. The samples were ground to which acetonitrile/water solution was added. After filtering, the extract was transferred into a MycoSepTM purifying column and was pressed slowly. Then the purified liquid was derivatized with trifluoroacetic acid (TFA) and assayed using high performance liquid chromatography (HPLC). Results AFs were detected in 70.27% of corn samples, with a mean level of 27.44 μg/kg and the highest level of 1098.36 μg/kg. In peanut, the AFs detection rate was 23.08%, with a mean level of 0.82 μg/kg and the highest level of 28.39 μg/kg.Very few rice samples with AFs were detected. The AFs levels were very low in walnut and pine nut. Conclusion Corn is the food most seriously contaminated with AFs in China. AFB1 is the main aflatoxin which is found as a contaminant in foods.

    The multidrug resistance 1 gene (MDR1) encodes for P-glycoprotein (P-gp), which plays a pathophysiological role in the development of autoimmune diseases, including systemic lupus erythematosus (SLE). Herein, we aimed to investigate the relationship between MDR1 gene polymorphisms and SLE susceptibility in the Chinese Guangxi population. The genotypes of rs1128503 and rs1045642 in MDR1 gene were analyzed using the polymerase chain reaction-restriction fragment length polymorphism method in 283 SLE patients and 247 healthy controls from Guangxi. Direct sequencing method was used to verify the results. Binary logistic regression analyses adjusting for gender and age indicated that subjects carrying the rs1128503 T-allele and TT genotype were at increased risk of SLE when compared to carriers of the C allele and CC genotype, with adjusted ORs of 1.36 (95% CI 1.07-1.74; P = 0.014) and 1.77 (95% CI 1.08-2.88; P = 0.022), respectively. In addition, the risk allele T had a recessive effect (OR 1.49, 95% CI 1.04-2.14, P = 0.029). Subgroup analyses revealed effect modification by age for the presence of the rs1128503 T allele, yielding a significant positive association with SLE in older (≥40 years) subjects (T vs. C allele: OR 1.41, 95% CI 1.01-1.96; P = 0.041; TT vs. CC genotype: OR 1.74, 95% CI 1.07-2.79; P = 0.021). For the first time, we demonstrated that MDR1 rs1128503 polymorphisms were associated with SLE susceptibility in Chinese Guangxi population.

    Based on the 1951-2006 climatic observation data from 224 meteorological stations in South China (Guangdong Province, Guangxi Autonomous Region, and Fujian Province) and the historical information about the chilling injury losses of banana and litchi, the accumulated harmful chilling for the processes with minimum daily temperature zoning for banana and litchi's chilling injury were drawn, and the spatial variation of climatic risk for banana and litchi's chilling injury was commented. The results indicated that in the study area, climate warming might lead to the decrease of cold resistance of banana and litchi, which could increase the disaster risk of chilling injury. The geographical distribution of climatic risk probability for banana and litchi's chilling injury showed a zonal pattern. According to the integrated climatic risk index, the banana and litchi's chilling injury region was divided into three risk types, i.e., high risk, moderate risk, and low risk, which provided an important basis for the adjustment of agricultural production structure.

    2000-01-01

    The Huanan (South China) subcontinent was created by amalgamation of the Yangtze, Xianggan, Cathaysia and Zhemin microcontinents by the Guangxi orogeny in the Early Palaeozoic. The closure of the Tethyan Ocean and subsequent collision event outside the amalgamated continent reactivated fossil sutures and resulted in intracontinental (ensialic) orogenies in the Mesozoic. Based on evidence from deformation, molasse and granitoids, the Sichuan-Guizhou-Hunan-southern Hubei and Hunan-Jiangxi-Fujian Yanshanian fold-thrust systems and the Lower Yangtze-northwestern Fujian Indosinian fold-thrust system are thought to be intracontinental orogens. Their main features are as follows: intracontinental orogenies occurred areally, thrusting propagated towards the interior of the continental, they extend parallelly to the strikes of the fossil sutures, and the details of the temporal-spatial evolution of the orogens depend on subduction-collision events.

    2014-10-01

    Female sex workers (FSWs) play a key role in HIV/AIDS transmission and their gatekeepers play a crucial role in shaping their behaviors. Limited studies are available on the relationship between FSWs and gatekeepers. In the current study we used an ethnographic approach to examine the dynamic and multidimensional relationship of FSWs and their gatekeepers from the perspectives of both parties. We recruited 38 FSWs and 16 gatekeepers from different types of commercial sex venues in Guangxi, China, and conducted in-depth individual interviews. Our data suggest that FSWs and gatekeepers maintain an interdependent and reciprocal relationship during their business practice, but gatekeepers exert significant influence and control over FSWs. Designing culturally appropriate HIV/STI-prevention programs requires us to take advantage of the unique and crucial roles of gatekeepers. We conclude with a call for structural interventions to protect FSWs' occupational health and safety.

    China's coastal areas have led the rest of China in economic development and low fertility rates; migration from inland areas and urbanization are well advanced. A symposium on China's coastal population and economic development was conducted in 1990 by the Population Research Institute of the Chinese Academy of Sciences, the Liaoning Population Institute, and the Dalian Population Institute at the request of the China Population Institute. There were 50 people in attendance representing major research institutes and family planning associations and media organizations. 26 papers were submitted. The opening speaker addressed developing the economy as a positive cycle of population and development, and accelerating change. Discussion focused on the following topics: the relationship between fertility rate changes and coastal economic development, population mobility and migration to coast areas, population urbanization, and related problems. In the summation by Professor Tian Xueyuan, 7 trends were identified: continued coastal population growth, a two-directional change in natural population growth, an increase in the rate of coastal population migration, rapid urban population growth, productive age population growth and changes in the employment structure, improvements in economic and technological progess and quality of life, and rapid population aging. The symposium was considered particularly timely in highlighting the current problems and strengths, integrating theorists with field workers, and maintaining an open exchange of ideas and information. Problems were identified as regional open areas in Heihai in Guangxi, Heihe in Heilongjiang, and Dalian in Liaoning Province. Although the population is considered professionally better qualified than in other regions, there is still a lack of technicians and skilled workers and an excess of untrained workers. Development is being slowed and mismanaged due to deficiencies in the job allocation and personnel

    Sex workers in China are routinely coercively detained through administrative mechanisms outside of legal procedures, but very little is known about the anthropologic and public health context of these policies. This biosocial analysis of female Chinese sex worker detention uses ethnographic, legal, and public health data to describe social suffering and countervailing social justice responses among incarcerated sex workers (ISW) in China. Compared to sex workers not detained in China, ISW face substantive inequalities inscribed in physical and psychological suffering. Chinese sex worker detention camp practices may not only systematically increase HIV/syphilis risk among ISW, but also work to narrow women's social spheres of influence, a particularly cruel tragedy in a Chinese social system that highly values social and personal connections. A limited empiric analysis of Guangxi Province STI clinic data shows that cities detaining sex workers have higher mean HIV prevalence compared to cities that do not detain sex workers. While incipient medical and legal movements in China have generated momentum for expanding ISW services and resources, there is still substantial variation in the implementation of laws that ensure basic life-saving medical treatments. Post-incarceration social justice programs for sex workers linking women to essential STI/HIV resources, reconnecting broken social lives, and helping restore interpersonal relationships are urgently needed.

    Western China includes 12 provincial divisions (the 7 provinces of Sichuan, Guizhou,Yunnan, Shaanxi, Gansu, Qinghai and; 5 autonomous regions of Tibet, Ningxia, Xinjiang, Inner Mongolia and Guangxi; and one city of Chongqing), which comprise 71.4% of the national land area,28.5% of the national population and produce 17.5% of the national GDP in China. There are 17countries that have riparian relationships with western China, most of which are water-short countries. All are listed by UN ESCAP as countries with potential water crisis. The co-operative development and coordinated management of international rivers in western China is an important step toward the implementation of the national Great Western Development program. Taking into account of the national strategy and object hierarchy, as well as the development demand of the western region, it is necessary to pursue the multi-disciplinary study of the equitable allocation,utilisation, and eco-environment protection of transboundary water resources in the region. Such efforts will undoubtedly provide scientific evidence and support for the decision-making of the environmental protection and ecological construction and management in the western regions, the enforcement of the sub-regional economic co-operation, mitigation of trans-boundary conflicts, and enhancing bio-diversity conservation.

    There have been relatively few attempts to model the distributions of the fruit flies Ceratitis capitata (Wiedemann), Ceratitis cosyra (Walker), and Ceratitis rosa Karsch in China, but the geographic distributions of these species are of considerable concern in terms of biosecurity. In this study, two different modeling methods (genetic algorithm for rule-set prediction [GARP] and maximum entropy species distribution modeling [Maxent]) were used to predict the potential distributions of these three fly species in China, by using distribution records and a set of environmental predictor variables. The results showed that Maxent performed well, compared with modeling by GARP, at each test threshold. For all three species, the results predicted by Maxent agreed with the observed distributions in Africa and in other parts of the world. In China, C. capitata seems to have the highest number of favorable habitat areas, relative to C. cosyra and C. rosa, i.e., Yunnan, Guizhou, Guangxi, Guangdong, Hainan, Fujian, Sichuan and Chongqing, whereas C. cosyra has the smallest range of suitable areas, i.e., Yunnan, some parts of Hainan and Sichuan. The suitable areas for C. rosa are mainly restricted to Yunnan, Hainan, southern Guangdong, and a few areas of Sichuan. The indications are that on the whole, Southwest and South China are the areas with the highest risk for establishment from these three fly species. Jackknife tests reveal that environmental variables associated with temperature have the strongest influence on the potential distributions of all three species relative to other variables.

    A total of nine tin-contained ancient glass beads were characterized by a combination of scanning electron microscopy coupled with energy-dispersive X-ray spectrometry and Raman spectroscopy. These glass beads dated from 1st century BC to 10th century AD were excavated from the Xinjiang and Guangxi provinces of China. Two kinds of tin-based opacifiers/colorants included crystalline cassiterite (SnO(2)) and lead-tin yellow types II were first found in these soda lime glass beads. The tentative chronology of the tin-based opacifiers/colorants used in ancient glasses from China and the West was compared. In addition, several transition metal ions colorants were also found in these beads. The detailed study of the glassy matrices, crystalline inclusions, and the microstructural heterogeneities for these glass beads has revealed some valuable information to trace the possible making technology and provenances.
