Treatments with nonsteroidal anti-inflammatory drugs (NSAIDs) have increased the number of patients with gastrointestinal complications. Qing Dai has been traditionally used in Chinese herbal medicine for various inflammatory diseases such as ulcerative colitis. We previously reported that Qing Dai suppressed inflammations by scavenging reactive oxygen species (ROS) in ulcerative colitis patients. Thus, Qing Dai can attenuate the production of ROS, which play an important role in NSAID-induced gastrointestinal injuries. In this study, we aimed to elucidate whether Qing Dai decreased mitochondrial ROS production in NSAID-treated gastrointestinal cells by examining cellular injury, mitochondrial membrane potentials, and ROS production with specific fluorescent indicators. We also performed electron paramagnetic resonance measurement in isolated mitochondria with a spin-trapping reagent (CYPMPO or DMPO). Treatments with indomethacin and aspirin induced cellular injury and mitochondrial impairment in the gastrointestinal cells. Under these conditions, mitochondrial alterations were observed on electron microscopy. Qing Dai prevented these complications by suppressing ROS production in gastrointestinal cells. These results indicate that Qing Dai attenuated the ROS production from the NSAID-induced mitochondrial alteration in the gastrointestinal epithelial cells. Qing Dai treatment may be considered effective for the prevention NSAID-induced gastrointestinal injury.

Qing fei tang, which is used for various respiratory diseases, is useful for reducing relapse of aspiration pneumonia and bronchopneumonia in stroke, but the effect remains unknown in Parkinson's syndrome. We report two cases of Japanese patients with progressive supranuclear palsy and relapsing aspiration pneumonia and bronchopneumonia, which was successfully prevented by qing fei tang. Two Japanese men with progressive supranuclear palsy and receiving total enteral feeding (patient one (66-years-old) and patient two (76-years-old)) had experienced recurrent aspiration pneumonia and bronchopneumonia, which was unresponsive to conventional therapy. The respiratory infection developed twice at intervals of two months in patient one, and nine times at almost monthly intervals in patient two. Thereafter, they were given qing fei tang. After administration of qing fei tang, the respiratory infection reoccurred only once; after 5.5 months for patient one, and six months for patient two. Both of our patients clearly showed a reduced incidence of respiratory infection. Both of our patients clearly showed a reduced incidence of respiratory infection after the administration of qing fei tang. Qing fei tang could be useful for the prevention of recurrent aspiration pneumonia and bronchopneumonia in progressive supranuclear palsy.

Color glazes of Ming and Qing official kilns are excellent representatives of the famous ancient Chinese porcelains. The study of official ware with Jilan glaze has been an important topic. But it made slow progress due to the rarity of samples with strict production management and using system. The recipes, chemical composition and chromaticity characteristic of the Jilan samples excavated from official kilns in the Ming and Qing dynasties were first discussed by systematical testing with the energy dispersive X-ray fluorescence (EDXRF) and color difference meter. The results showed that the porcelain stone content in Jilan bodies of official kiln in the Ming dynasty is higher than the samples of the Qing dynasty. The manganese content in Jilan glazes of the Ming dynasty is higher than that in the Qing dynasty, while the glaze ash addition and the lightness value in the glaze are opposite.

The Holocene evolution of the Qing'ao embayment, Nan'ao Island, southern China, is primarily the result of the interaction of tectonic activity, climate variation and changes in relative sea level. Characterizing the evolutionary history of the relatively small Qing'ao embayment during the Holocene will help improve our understanding of the driving mechanisms of coastal evolution in the area. To reconstruct the Holocene evolution history we analyzed the grain size, loss on ignition (LOI) and carbonate content of modern and core samples. Modern environmental analogs were examined in surface samples ranging from the coastal sand dunes through to offshore. The results of these modern samples suggest that dune sand (mean size of ~2.33Phi) are slightly finer than beach sand (mean size of 2.13Phi), and nearshore sediment is much coarser than offshore sediment (mean size of 5.90Phi). This modern analogs were then applied to 8 percussion cores from the Qing'ao embayment. A chronological framework obtained from 11 radiocarbon samples suggests that the embayment started to accept deposition since early Holocene, ~8500 cal. yr. BP. Three main phases of Holocene evolution were identified. A basin wide shell-rich sand sheet forms the basal Holocene facies and overlies clay rich presumably Pleistocene sediments or bedrock. This facies records an initial sedimentation phase associated with the early Holocene transgression into the embayment (~8500-6000 cal. yr. BP). The basal facies grades upward to a mixed sandy-mud facies which includes lagoonal clayey-silts, flood tide delta sands and records an estuarine phase lasting from ~6000-1000 cal. yr. BP that appears coincident with falling regional sea levels. Coincident with the estuarine phase is a period of coastal dune building recorded as yet undated massive sands that are found in the upper fill. Toward the end of the estuarine phase it is apparent that dune migration has restricted the lagoon entrance and that this was

Chinese herbal medicine Qing-Dai (also known as indigo naturalis) has been used to treat various inflammatory conditions. However, not much has been studied about the use of oral Qing-Dai in the treatment for ulcerative colitis (UC) patients. Studies exploring alternative treatments for UC are of considerable interest. In this study, we aimed at prospectively evaluating the safety and efficacy of Qing-Dai for UC patients. The open-label, prospective pilot study was conducted at Keio University Hospital. A total of 20 patients with moderate UC activity were enrolled. Oral Qing-Dai in capsule form was taken twice a day (daily dose, 2 g) for 8 weeks. At week 8, the rates of clinical response, clinical remission, and mucosal healing were 72, 33, and 61%, respectively. The clinical and endoscopic scores, CRP levels, and fecal occult blood results were also significantly improved. We observed 2 patients with mild liver dysfunction; 1 patient discontinued due to infectious colitis and 1 patient discontinued due to mild nausea. This is the first prospective study indicating that oral Qing-Dai is effective for inducing remission in patients with moderate UC activity and can be tolerated. Thus, Qing-Dai may be considered an alternative treatment for patients, although further investigation is warranted. © 2016 S. Karger AG, Basel.

Zhongqiu Zhang

2014-01-01

Full Text Available This article studies the selection of a target country for succession of foreign laws by China of the late Qing Dynasty as well as the channels and approaches based on documentation in the Chinese language. According to this article, the selection was mostly limited by information, the national situation and political system, objectives, international environment, legal tradition as well as human and material resources, of which the national situation, political system and objectives serve as key factors. In this case, historically, China of the late Qing Dynasty looked at the United States, Britain, France and Germany before settling on Japan as the target country for the succession of foreign laws; and with respect to the channels and approaches for the succession, several relatively effective channels and approaches, such as studying aboard, translating foreign texts, making survey trips and hiring foreign experts, were employed. Such selection by China of the late Qing Dynasty for the purpose of succession of foreign laws provide us with useful references for thinking about law succession and the current exchange of laws and cultures b etween China and foreign countries.

This is a study of the possibility of identifying antique Chinese porcelains according to the period or dynasty, using major and minor chemical components (SiO2 , Al2O3 , Fe2O3 , K2O, Na2O, CaO and MgO) from the body of the porcelain. Principal component analysis is applied to published data on 66 pieces of Chinese procelains made in Jingdezhen during the Five Dynasties and the Song, Yuan, Ming and Qing Dynasties. It is shown that porcelains made during the Five Dynasties and the Yuan (or Ming) and Qing Dynasties can be segregated completely without any overlap. However, there is appreciable overlap between the Five Dynasties and the Song Dynasty, some overlap between the Song and Ming Dynasties and also between the Yuan and Ming Dynasties. Interestingly, Qing procelains are well separated from all the others. The percentage of silica in the porcelain body decreases and that of alumina increases with recentness with the exception of the Yuan and Ming Dynasties, where this trend is reversed.

Background: The Qing'e formula (QEF) is a well?known traditional Chinese prescription that has been clinically employed for treatment of bone disease for hundreds of years. Objective: The present study aims to observe the effects of different compatibilities of QEF on the scopolamine?induced learning and memory impairment in the mouse, and further to explore its action mechanisms and compatibility rationality. Materials and Methods: The learning and memory alterations in the mouse were evaluated using the step?down test and Morris water maze (MWM) test; the acetylcholinesterase (AChE) activity and brain?derived neurotrophic factor (BDNF) expression in the hippocampus were measured using colorimetric method or immunohistochemistry. Results: The results showed that different compatibilities of QEF significantly prolonged latency in the step?down test, shortened escape latency in the navigation test, increased the percentage of residence time, and the percentage of swimming distance in the target quadrant in the probe trial session. In addition, our results also found that different compatibilities of QEF remarkably inhibited AChE activity and increased BDNF expression in the hippocampus of mice. What's more, the group after being treated with whole recipe (QF) showed the highest level of improvement. Conclusions: These findings not only suggest that QEF may effectively ameliorate cognitive deficits through inhibiting AChE activity and increasing BDNF expression in the hippocampus but also elucidate the rationality of QEF.

Nao-Qing solution has been shown to be clinically effective in the treatment of acute ischemic stroke (AIS). The purpose of this study was to improve the pharmacokinetics and brain uptake of Nao-Qing, administered as an oil-in-water microemulsion. Sprague-Dawley (SD) rats were given Nao-Qing microemulsion by intranasal or intragastric routes. Samples of blood, brain, heart, liver, lung and kidney were collected at pre-determined time intervals, and the contents of ginsenosides Rg1 and Rb1 (active ingredients of the Nao-Qing microemulsion) were analyzed by high-performance liquid chromatography (HPLC). The results showed that contents of ginsenosides Rg1 and Rb1 in Nao-Qing microemulsion was 8475.13 ± 54.61 μg/ml and 6633.42 ± 527.27 μg/ml, respectively, and that the particle size, pH and viscosity of the microemulsion were 19.9 ± 5.07 nm, 6.1 and 3.056 × 10(-3 )Pas, respectively. Absorption of ginsenoside Rg1 was higher than that of ginsenoside Rb1, which was barely detectable after intragastric administration; furthermore, the concentration of ginsenoside Rg1 in blood and other tissues at each time point was lower for intragastric than for intranasal administration. Compared with intragastric administration, intranasal administration resulted in a shorter tmax (0.08 versus 1 h), a higher Cmax (16.65 versus 11.29 μg/ml), and a higher area under the concentration-time curve (AUC) (592.91 versus 101.70 μgċh/ml) in the brain. The relative rates of uptake (Re) and the ratio of peak concentration (Ce) in the brain were 126.31% and 147.48% for ginsenoside Rg1, respectively. These data illustrate that intranasal administration can promote the absorption of drugs in Nao-Qing microemulsion and achieve fast effect.

The Characters of Leap Years in Qing Calendars (1644-1911)

Science.gov (United States)

Lu, Dalong

In Qing Dynasty (1644-1911) three different calendars had been put into use which titles are Xiyang Xinfa Lishu (Treatise on Astronomy and Calendrical Science according to the New Method in West 1645-1666) Yuzhi Lixiang Kaocheng (Compendium of Calendrical Science and Astronomy compiled by Imperial Order 1725-1742) and Yuzhi Lixiang Kaocheng Houbian (Sequel Compendium of Calendrical Science and Astronomy compiled by Imperial Order 1742-1911). The characters of leap years in the three calendars are different for the last one which is selected the year of 1723 as it epoch and named as Guimao Yuan Li. This calendar is based on the 33-year pattern of leap years (there is a rather exact accord between days and years over this interval with eight days being intercalated per 33 years) and is slightly different from the former two calendars. Therefore the calendars of Qing Dynasty complied by Western Jesuits and Chinese astronomers can be regarded as the remarkable achievements in the history of calendar in the world.

"To Feel at Home in the Wonderful World of Modern Science": New Chinese Historiography and Qing Intellectual History.

Sela, Ori

2017-09-01

Argument In recent decades a large body of scholarship on the first half of twentieth-century China has successfully shown the ways in which history and historiography had been constructed at the time, as well as the links between history, national identity, education, and politics that was forged during this period. In this paper, I examine Qing intellectual history, in particular that of the mid or "High Qing." I discuss the development of the historiography of this field in the early twentieth century by drawing on the larger developments in historiography; by demonstrating how these developments had shaped Qing intellectual history for later times; by focusing on the historical actors' sense of the importance of "science," being "scientific," and "modernization"; and, by unraveling the intimate connections to older historiographical narratives going back all the way to the eighteenth and nineteenth centuries.

Xin'an imperial medical officials of the Ming and Qing Dynasties was a special group of Xin'an doctors. It had exerted a positive and active impact on the development of traditional Chinese medicine. Rooted in the Xin'an region, with higher literacy and noble medical ethics and medical knowhow, through the imperial enlistment, examination, and other ways to enter the palace as imperial medical officials. During their tenure, they wrote books and communicated and merged with the folk medicine actively. After retiring, they were still involved actively in folk medicine activities, thus promoting and influencing the development of local medicine. The formation of Xin'an community of imperial medical officials in the Ming and Qing Dynasties was closely related to the prosperity of regional culture and commerce, and the development of medicine in Xin'an region.

Orally administered Qing-dai, called indigo naturalis in Latin, is reportedly useful for the treatment of ulcerative colitis. We herein describe two patients with ulcerative colitis who developed colitis with wall thickening and edematous changes during oral administration of the powdered form of Qing-dai. In Case 1, a 35-year-old man developed colitis similar to ischemic colitis with bloody stool that recurred each time he ingested Qing-dai. He had no signs of recurrence upon withdrawal of Qing-dai. In Case 2, a 43-year-old woman underwent ileocecal resection for treatment of an intussusception 2 months after beginning oral administration of Qing-dai. Edema and congestion but no ulceration were present in the mucosa of the resected specimen. Both patients exhibited abdominal pain with bloody diarrhea, and abdominal computed tomography showed marked wall edema affecting an extensive portion of the large bowel.

The Images of Jesus in the Emergence of Christian Spirituality in Ming and Qing China

Xiaobai Chu

2016-03-01

Full Text Available Images of Jesus Christ played an important role in the emergence of Christian spirituality in Ming and Qing China. Of the great many images that we know from this period, this paper introduces five of them: Jesus as infant, criminal, gate, brother, and pig. The paper unfolds the historical, anthropological, and theological layers of these images to reveal the original tension between Christian spirituality and Chinese culture. The central thesis of the paper therefore is that this tension is reflected in the images of Jesus Christ and, moreover, that analyzing this tension allows us to achieve a more profound understanding of the emergence of Christian spirituality in Ming, Qing, and perhaps even today’s China.

Objective: To evaluate whether oral administration of Chinese traditional medicine, Qing-Xue granula, can prevent mouse lung injury caused by thoracic radiation. Methods: 128 BalB/C mice were divided into 4 groups: control (C) group; radiation (R) group; radiation plus high dose Qing-Xue granula (H) group and radiation plus median dose Qing-Xue granula (M) group. The H and M groups were fed 0.64 g and 0.32 g of Qing-Xue granula dissolved in 0.5 ml saline once daily for two months,which were 4 and 2 times of human dosage, respectively. Whole thorax radiation of 12 Gy was delivered with a single ventral-dorsal field with 6 MV X-ray. Group C and group R received 21 days of 0.5 ml saline feeding. Mice were sacrificed at 1, 2, 4 or 6 months after radiation. Macrophage cell count of lung lavage fluid and hydroxyproline content of left lung were assayed, and the lung fibrosis was scored according to the Ashcroft's criteria. The plasma interleukin-6 (IL-6) and vascular endothelial growth factor (VEGF) concentration were assayed with ELISA method. The One-way ANOVA was used to test the significance of any differences between groups at each time point. Results: The macrophage cell number of lung lavage fluid was significantly lower in the 1 st month in group M than in group R (2:4, q =3.92, P 0.05). The hydroxyproline content of group H was significantly lower than group R in the 1 st and 6 th months (q =3.62, 3.54, all P nd , 4 th and 6 th months (q=3.38 -4.16, all P st month (q=3.53, P 0.05). The VEGF concentration was significantly higher in group R than group C since the 2 nd month (q =3.12 - 3.78, P nd and 6 th months (q =3.08 - 3.92, all P<0.05). Conclusions: Oral Chinese traditional medicine, Qing-Xue granula, could prevent radiation induced lung fibrosis in mice, especially at high dosage. The degree of elevation of VEGF in plasma was not parallel with that of lung fibrosis. (authors)

The female healer is a special community in traditional Chinese medical professionals. Since the Song-Yuan Dynasties, although the literati class holding the social voices and the male healers acting as medical orthodoxy were always suspicious of the female healers' behaviors and their medical morality, and tarnished their images through all kinds of media. Meanwhile, the female healers were still badly needed on the account of recognition of distinction between sexes between both sexes due to the rising of neo-Confucianism. An excellent female healer could still earn wide respect from the society. Gu Dehua was a famous female healer from Wuzhong in the Qing Dynasty's Daoguang-Xianfeng period. By investigating Gu Delua's family conditions, deeds and works, and her career, the community of the female healers in the Ming-Qing Dynasties can be thus understood.

Today, along with the constantly updated techniques, the recording method for the current situation of interior decoration has gradually developed from two-dimensional drawings into digital and comprehensive record. However, the current research results are mostly limited to a single field. This paper takes the digital record and reproduction about the current situation of interior decoration in Jingfu Palace in the Forbidden City as an example. Through the use of photogrammetry, 3D laser scanning, virtual display and other technology and equipment at the forefront of architectural field, it makes qualitative and quantitative record about the interior decoration inside Jingfu Palace. By combing with the interpretation of historical documents, it restores the original design ideas hidden behind the current situation of interior decoration, so as to summarize the best recording and reproducing method of interior decoration of Qing Dynasty.

The funeral procession of Sheng Xuanhuai (, 1844-1916) - the renowned Qing scholar-official, financier, and "father of Chinese industrialism" - meandered through the streets of Shanghai on 18 November 1917. The funeral was a grand event, one that was purportedly documented in film, later to be distributed as the first "news short-film" () in China. The North China Herald reported on the event in some detail, at times in rather florid language, and suggested that "the cortege was splendid and impressive, bringing back the days of the Manchu emperors. The ceremonial costumes, the musical instruments and much more of the accoutrements dated back to the days of the Empire" ("Sheng Kung-pao's Funeral," 1917, 467-68). And indeed, the procession included a variety of ritual customs and insignia from Qing (1644-1911) times: imperial banners, ancestral tablets, Buddhist and Daoist priests, paper artifacts, and much more. Simultaneously, nonetheless, other kinds of participants and objects - new and not of imperial pedigree - were part of and intermixed with the older materials: certificates of rank were carried on cars; boy scouts and college students marched alongside the priests; many of the participants arrived by train (mainly from Sheng's hometown, Suzhou); and as the Shanghai portion of the procession ended, it continued by steamer to Suzhou. The conclusion of the North China Herald account, however, seems to have emphasized a dichotomy of old and new rather than a joyful mix of the two: Hundreds of men, dressed in the ancient costume of the old dynasties, bore a strong contrast to the eight behind them, sons of intimate friends of the deceased. They were on horseback and wore high silk hats, frock coats and white breeches tucked in riding boots. Truly the passing of the old and the entering of the new. (Ibid.; emphasis added) This view - the old giving way to the new - was not just an off-hand (Western) journalistic analysis; it was part of a larger discourse about

The effect of Kou Yan Qing Ke Li on the prevention and treatment of radiation-induced oral mucositis was investigated in patients with nasopharyngeal carcinoma. Sixty patients with nasopharyngeal carcinoma to be treated with radiotherapy were randomized into two groups: the experimental and control groups. The experimental group (30 patients) was treated with Kou Yan Qing Ke Li during the full course of radiotherapy. The control group (30 patients) rinsed their mouths in the same way with mouth washes containing 0.9% sodium chloride injection, lidocaine, dexamethasone, vitamin B2 and B2 gargle liquid mixture, when grade 2 and above radiation-induced oral mucositis appeared in the process of radiation. Radiation-induced oral mucositis was assessed according to the radiation therapy oncology group criteria. The time of occurrence and degree of pain grade were compared between the two groups. The first onset of oral mucositis in the experimental group (12.40 d ± 2.74 d) was later than that in the control group (9.46 d ± 1.39 d) (t = 5.241, P Qing Ke Li could delay the time of occurrence of radiation-induced oral mucositis, reduce the severity of radiation stomatitis, alleviate the pain of patients, improve the clinical symptoms of patients, and effectively prevent and treat radiation-induced oral mucositis in patients with nasopharyngeal carcinoma.

The Tangdan Copper Mines and the 1733 Earthquake: A Mining Community before the Boom in the Far Southwest of Qing China

2014-12-01

Full Text Available In the official records, copper mines in the southwest of the Qing empire seem to suddenly appear in the late 1730s. In part, this impression is an effect of government attention. Copper, which was the most important metal for casting cash coins, became a pressing concern when imports of Japanese copper dwindled. The government responded by developing domestic resources. Seemingly overnight, Yunnan mines reached impressive levels of productivity and replaced imports. For several decades, the Tangdan mines in northeastern Yunnan supplied most of the copper consumed by the centrally important metropolitan mints. The sudden boom is remarkable and not entirely plausible. This article reassesses the history of Qing-period mining by examining a particular case study. It explores an essay about the Dongchuan earthquake of 1733 that provides a glimpse at the empire’s leading copper mines on the eve of the recorded boom. A close analysis of figures, mining technology, and organizational structures reveals that the mines had been developed by mining entrepreneurs and migrant workers for a considerable period of time outside government attention, operating in a gray zone of unlicensed exploitation. The studied case permits a new assessment of the role of the state and of nonstate players in the industry. Moreover, it throws a new light on the image of Qing society and economy created by the official emphasis on agriculture and the actual role of the nonagrarian sector.

This paper collected and analyzed literatures about starting of traditional medicine and trading of different medicine from Chunqiu Zhanguo to Ming and Qing Dynasties, in order to preliminarily explore on an overview of specie of chinese exotic traditional medicine and trade of different country in different dynasty（from Chunqiu to Ming and Qing Dynasties）, as well as the amount of exotic medicine over two thousand years. (remove repeating and doubtful species), find peculiarity of exotic medicine, sreen species that used to develop the Silk Route and establish quality standards.Finally, We get conclusions are as follows. First, primary,.prosperous and declining stages of development of exotic traditional medicine are Qin and Han, Song-Jin-Yuan, Ming and Qing Dynasties, respectively. Second, according to literature, the stage that has the most species of exotic medicine is song dynasty,approximately have 300. Removing repeating and doubtful species, the believable species are approximate 230 to 250. Meanwhile, the unknown species are approximate 30, which may be different name of one medicine or processed goods, now these medicines are named as "doubtful species". Third, the medicinal parts of exotic medicine are different from Chinese medicine of Han nation. The number of Resin, fruits and seeds kind are more than root and rhizomes kind,mineral medicines are more than animal. Fourth, the major producing area of exotic medicine is some countries and territories related to the Silk Route in the history. Ultimately, this paper preliminarily figure out basic information of exotic medicine of different dynasty in China,that provide reference for learning study and decision of industrial development.

Xiao-Qing-Long-Tang is a traditional Chinese formula used for the treatment of cold syndrome, bronchitis, and nasal allergies for thousands of years. However, the in vivo integrated metabolism of its multiple components and the active chemical constituents of Xiao-Qing-Long-Tang remain unknown. In this study, a method using ultra high performance liquid chromatography coupled with quadrupole time-of-flight tandem mass spectrometry was established for the detection and identification of the metabolites in human and rat urine after oral administration of Xiao-Qing-Long-Tang. A total of 19 compounds were detected or tentatively identified in human urine samples, including eight prototypes and 11 metabolites. Also, a total of 50 compounds were detected or tentatively identified in rat urine samples, including 15 prototypes and 35 metabolites detected with either a highly sensitive extracted ion chromatogram method or the MS E determination using Mass Fragment software. Our results indicated that phase Ⅱ reactions (e.g. glucuronidation and sulfation) were the main metabolic pathways of flavones, while phase I reactions (e.g. demethylation and hydroxylation) were the major metabolic reaction for alkaloids, lignans, and ginger essential oil. This investigation provided important structural information on the metabolism of Xiao-Qing-Long-Tang and provided evidence to obtain a more comprehensive metabolic profile. © 2017 WILEY-VCH Verlag GmbH & Co.

Cancer cachexia is characterised by the loss of body mass and directly compromises immune response and the quality of life of cancer patients. In the present study, we set out to investigate the role of Chinese herbs as anticancer medicines and/or chemotherapeutic adjuvants to increase therapeutic efficacy and/or ameliorate given side-effects in animal model. Twelve kinds of herbs were chosen from the ingredients of major Chinese herbal medicines, and their effects on the antioxidant activity were investigated. To obtain the anticancer effects of 5-fluorouracil (5-FU) when consumed with minimal side-effects, we investigated the combination effect of Scutellaria baicalensis and Qing-Shu-Yi-Qi-Tang that may enhance the anticancer activity of 5-FU on subcutaneous tumour growth in C57BL/6 mice challenged with Lewis lung carcinoma cells. Qing-Shu-Yi-Qi-Tang, a multiple-component herbal extract, was shown to have high anti-oxidation activity, while S. baicalensis (Chinese skullcap) was demonstrated to have high tumour-growth inhibition activity. Thus, S. baicalensis and Qing-Shu-Yi-Qi-Tang were evaluated for their combinaton effects on the cancer-induced cachectic murine upon receiving 5-FU chemotherapy. As a result, tumour masses and losses of carcass and/or gastrocnemius muscle were found to be significantly decreased. This combination otherwise increased both Th1/Th2 ratio and NK cytotoxicity. In the mice receiving with or without 5-FU, the serum levels of monocyte chemoattractant protein-1 (MCP-1) increased by all means but otherwise decreased when the herbal combination was administrated. Additionally, the expressions of nuclear factor-kappa B (NF-κB) and muscle RING finger protein-1 (MuRF-1) decreased in the gastrocnemius muscle when the herbal combination was applied. Our results revealed that the combination of S. baicalensis and Qing-Shu-Yi-Qi-Tang is able to ameliorate cachectic symptoms and positively stimulate anti-tumour immunity while undergoing

During the one hundred years and more from the beginning of the 18th century to the beginning of the 19th century, about 16 Chinese doctors, at the invitation of Japanese, went to Japan successively by trade ships to practice medicine and teach Chinese medicine. They also conducted academic exchanges with Japanese doctors. Because both the Japanese authorities of that time and the emperor of Qing dynasty implemented the policy of closing the country, they could only do things in certain areas within limited time. By consulting a vast amount of data and following the footprints of some of the Chinese doctors in Japan, the author has got things into shape about the comings and goings of the doctors who went to Japan during the century and their activities, with the stressed point laid on the achievements of such influential doctors as Zhu Laizhang, Zhu Zizhang, Zhou Qilai, Zhao Songyang, Li Renshan, Hu Zhaoxin and so on.

The “Moso” (麽些) during the Ming and Qing dynasties includes present day Naxi, as well as the present day Mongolians in the areas of Muli, Yanyuan, and the “Nari” and“Namuyi” branches of the Tibetan . The Moso were distributed in the present day area of Lijiang , Diqing, Nujiang;the Mangkang area of Changdu;the Muli, Yanyuan, and Yanbian areas of Liangs-han Prefecture; and Batang and Litang of Ganzi Prefecture .Due to the special geographic environ-ment as well as policies implemented by various dynasties regarding the ethnic people in the border areas, the Moso formed a kind of culture with their own characteristics during the long process of histo-ry.In different historical periods , the Moso's cos-tume and culture also differed-some parts there were passed down , but there was also innovation and development .The regional characteristics of the Moso costume were obvious during the Ming and Qing dynasties.This article, from the perspec-tive historical geography , will discuss the geo-graphical distribution , evolution and formation of Moso costume during the Ming and Qing periods . 　　Costume is a marker of an “ethnic group” , and it includes both clothes and ornaments .Seen from the vertical line of history , the costume of Moso people has various characteristics in various periods;and seen from the horizontal line of histo-ry, the costume has very obvious regional differ-ences.There are few records on Moso costumes before the Ming dynasty .Only a few records are found, for example, in the shiji· xinanyi liezhuan ( An Account of the Southwestern Yi in The Records of the Historian) , xintangshu· nanman zhuan ( An Account of the Southern Barbarians in the New Tang History) .Since the Ming dynasty , there are more records about the Moso in Han Chinese litera-ture in which new characteristics of Moso costume could be noted .A kind of regional distribution of Moso costume appeared , including the Lijiang cos-tume zone , and the Yanyuan

Full Text Available We evaluated the inhibitory effect of 12 Chinese teas on leukocyte-type 12-lipoxygenase (LOX activity. Tea catechins such as epigallocatechin gallate have been known to exhibit leukocyte-type 12-LOX inhibition. Qing Shan Lu Shui, which contains lower catechin levels than the other tested teas, suppressed leukocyte-type 12-LOX activity. To characterize the bioactive components of Qing Shan Lu Shui, leukocyte-type 12-LOX inhibitory activity–guided fractionation of the aqueous ethanol extract of the tea was performed, resulting in the isolation of two new monoterpene glycosides: liguroside A (1 and B (2. The structures of compounds 1 and 2 were characterized as (2E,5E-7-hydroperoxy-3,7-dimethyl-2,5-octadienyl-O-(α-L-rhamnopyranosyl-(1″→3′-(4′″-O-trans-p-coumaroyl-β-D-glucopyranoside and (2E,5E-7-hydroperoxy-3,7-dimethyl-2,5-octa-dienyl- O-(α-L-rhamnopyranosyl-(1″→3′-(4′″-O-cis-p-coumaroyl-β-D-glucopyranoside, respectively, based on spectral and chemical evidence. Ligurosides A (1 and B (2 showed inhibitory effects on leukocyte-type 12-LOX activity, with IC50 values of 1.7 and 0.7 μM, respectively.

Quanti-chanwei (1881) is the first technical book on human anatomy written in Chinese and brought to Modern China. It was compiled and translated on the basis of Anatomy, Descriptive and Surgical (first edition in 1858) by Henry Gray. Quanti-chanwei was published with intent to establish Chinese translations for terms referring to anatomy, and it gained broad support from medical missionaries who mainly served in Guangdong, Shanghai, and Fuzhou at that time. Quanti-tongkao (1886) was also complied and translated on the basis of Gray' Anatomy, Descriptive and Surgical. It was published from Jingshi Tongwen Guan, The Academy of Foreign Languages in the Qing dynasty, and they selected different words for the translation into Chinese from Quanti-chanwei. Thus, although Gray' Anatomy, Descriptive and Surgical played a great role in the introduction of Western Medicine into Modern China, there was no accordance between the national government and the provinces regarding Chinese translations for terms referring to anatomy.

The Dangers of 'Warming and Replenishing' (wenbu ) during the Ming to Qing Epistemic Transition.

2015-01-01

Through a case study of Zhao Xianke's One Principle through Medicine ( Yiguan ) (1617?) and Xu Dachun's (1693-1771) denouncements of this text, my article zooms in on divergent discourses on the safety and efficacy of medicinal substances and compounds in late imperial China. Although Xu Dachun's fierce attacks on the popular 'warming and replenishing' ( wenbu ) therapies can be situated in an epistemic shift from the cosmology of 'Song learning' ( songxue ) towards the philology of 'Han learning' ( hanxue ) and 'evidential research' ( kaozheng ), I argue that more complex issues were at stake as well. Changed political, social, ethical, and economic realities shaped new and multifaceted perceptions of the nature of medicine, the medical profession, and the usage of medicinals in the aftermath of the Ming to Qing transition.

He-Ying-Qing-Re Formula (HF) is a formula modified from "Si-Miao-Yong-An Decoction", a traditional Chinese medical classic emerged in the Qing dynasty and has been reported for treatment of vascular diseases. HF, containing 8 herbs, has been used in local hospital for decades as a complementary method for diabetic retinopathy (DR) with retinal vascular dysfunction. Clinical reports revealed HF could ameliorate vision defects, microaneurysms, hemorrhages and macular edema. The aim of this study is to investigate the anti-DR action of HF and its underlying mechanism experimentally. Chromatographic fingerprinting of HF and rodent model of DR were established; hypoglycemic effect of HF was measured by fasting, random blood glucose and glucose tolerance test; vascular degeneration was measured by retinal digestion; blood-retina-barrier (BRB) permeability was assessed with Evans Blue leakage assay. Advanced glycation end products (AGEs) were measured in vitro and in vivo level; Migration of retinal vascular endothelial cells were determined by wound healing and transwell chamber assays; permeability of endothelial monolayer was monitored with dextran transport. AGEs-related proteins and signaling were measured with immunoblotting and immunohistochemistry. Chlorogenic acid, ferulic acid and arctin were identified as major components in HF; HF suppresses retinal vasculature degeneration and BRB permeability damage without significant inhibition on hyperglycemia; HF reduces in vitro and in vivo formation of AGEs and AGEs-induced migration as well as permeability of retinal vascular endothelial cells. Expression of tight junction proteins Zo-1 and Claudin-1 was increased while activation of AGEs receptor and downstream signaling Akt were suppressed upon HF treatment. HF exhibits protective effect against diabetic retinopathy, which may be associated with inhibition on AGEs and recovery on endothelial dysfunction via modulation of tight junction and AGEs downstream signaling

Required cavity HOM deQing calculated from probability estimates of coupled bunch instabilities in the APS ring

Emery, L.

1993-01-01

A method of determining the deQing requirement of individual cavity higher-order modes (HOM) for a multi-cavity RF system is presented and applied to the APS ring. Since HOM resonator frequency values are to some degree uncertain, the HOM frequencies should be regarded as random variables in predicting the stability of the coupled bunch beam modes. A Monte Carlo simulation provides a histogram of the growth rates from which one obtains an estimate of the probability of instability. The damping of each HOM type is determined such that the damping effort is economized, i.e. no single HOM dominates the specified growth rate histogram

Qing Ye Dan is a well-known herbal drug that is widely used to treat viral hepatitis in the Yi and Hani minority regions in the Yunnan province of China. An LC-MS/MS method was developed to determine the levels of swertiamarin in rat plasma. Swertiamarin and naringin (internal standard, IS) were extracted from rat plasma using solid-phase extraction (SPE) to purify the samples. The pharmacokinetics of the following different administration methods of swertiamarin in rats were studied: oral administration of swertiamarin alone, a Qing Ye Dan tablet (QYDT) and co-administration of swertiamarin and oleanolic acid, with each method delivering approximately 20mg/kg of swertiamarin. Non-compartmental pharmacokinetic profiles were constructed by using the software DAS (version 2.1.1), and the pharmacokinetic parameters were compared using an unpaired Student's t-test. The results showed that the pharmacokinetic parameters Cmax, AUC0-∞, Vz/F and CLz/F were significantly different (P<0.05) among the three types of swertiamarin administration. The data indicate that oleanolic acid and the other ingredients present in QYDT could affect the pharmacokinetic behaviour of swertiamarin in rats. Copyright © 2013 Elsevier Ireland Ltd.

Between the Living and the Dead: Trauma Medicine and Forensic Medicine in the Mid-Qing.

Science.gov (United States)

Wu, Yi-Li

2015-03-01

This paper analyzes the influence of forensic medicine on therapeutic medicine through a case study of Qian Xiuchang and Hu Tingguang, two Chinese doctors who specialized in treating traumatic injuries. During the early nineteenth century, both men compiled medical treatises that sought to improve on a scholarly model of "rectifying bones" articulated in 1742 by the Imperially-Compiled Golden Mirror of the Medical Lineage . Both texts also incorporated information from forensic medicine, including official inquest diagrams and checklists promulgated by the Qing government. I show that they drew on these forensic materials to help address two interlinked medical issues: understanding the effects of injury on different parts of the body, and clarifying the location and form of the body's bones. Overall, I suggest that the exchange of ideas between the realm of therapeutic medicine and forensic medicine was an important epistemological strategy that doctors and officials alike employed to improve their knowledge of the material body.

The beiwusheng huiguan (`Meeting hall of the Five Northern Dynasties') is a building complex from the Qing dynasty (1636-1912 ad) located in Wafangdian, near Ziyang, in the south of the Chinese Province of Shaanxi. Two of the preserved halls are richly decorated with wall paintings dated probably in 1848 ad and representing scenes of the `Romance of the Three Kingdoms' and Confucian moral tales. They are a rare example of well-preserved mural paintings of high artistic value inside civil buildings. The aims of this paper are the chemical characterization and localization of organic materials used as binders and colorants in the wall paintings. A multi-analytical approach, consisting in the combined use of gas chromatographic-mass spectrometric techniques (GC/MS and Py-GC/MS) and high-pressure liquid chromatography with diode array detector (HPLC-DAD), was chosen for these purposes. Proteinaceous materials (animal glue and egg), saccharide material (fruit tree gum) and a siccative oil were identified in different paint layers supplying invaluable information about the painting technique used. Moreover, the analyses of organic dyes allowed identifying indigo and gallic acid in more than one sample adding fundamental information about Chinese artists' techniques in mural paintings, missing from the previous studies. To shed light on the gilding technique, the distribution of the painting materials was achieved by means of synchrotron radiation Fourier transform infrared spectroscopy (SR micro-FTIR) and X-ray fluorescence (SR micro-XRF). The results obtained from the multi-analytical approach enabled us to determine the organic materials both binders and organic colorants used by Chinese artisans, highlighting the high technical level achieved in nineteenth century. The binding media and the organic colorants identified, as well as their distribution, allowed the discussion on the painting technique used by the artists of the Qing dynasty giving information for the

We investigated the mechanism of epidemics with the impacts of climate change and socio-economic fluctuations in the Ming and Qing Dynasties in China (AD 1368-1901). Using long-term and high-quality datasets, this study is the first quantitative research that verifies the 'climate change → economy → epidemics' mechanism in historical China by statistical methods that include correlation analysis, Granger causality analysis, ARX, and Poisson-ARX modeling. The analysis provides the evidences that climate change could only fundamentally lead to the epidemics spread and occurrence, but the depressed economic well-being is the direct trigger of epidemics spread and occurrence at the national and long term scale in historical China. Moreover, statistical modeling shows that economic well-being is more important than population pressure in the mechanism of epidemics. However, population pressure remains a key element in determining the social vulnerability of the epidemics occurrence under climate change. Notably, the findings not only support adaptation theories but also enhance our confidence to address climatic shocks if economic buffering capacity can be promoted steadily. The findings can be a basis for scientists and policymakers in addressing global and regional environmental changes. Copyright © 2015 Elsevier Ltd. All rights reserved.

Lifestyle interventions among people with impaired glucose tolerance reduce the incidence of diabetes, but their effect on all-cause and cardiovascular disease mortality is unclear. We assessed the long-term effect of lifestyle intervention on long-term outcomes among adults with impaired glucose tolerance who participated in the Da Qing Diabetes Prevention Study. The study was a cluster randomised trial in which 33 clinics in Da Qing, China-serving 577 adults with impaired glucose tolerance-were randomised (1:1:1:1) to a control group or lifestyle intervention groups (diet or exercise or both). Patients were enrolled in 1986 and the intervention phase lasted for 6 years. In 2009, we followed up participants to assess the primary outcomes of cardiovascular mortality, all-cause mortality, and incidence of diabetes in the intention-to-treat population. Of the 577 patients, 439 were assigned to the intervention group and 138 were assigned to the control group (one refused baseline examination). 542 (94%) of 576 participants had complete data for mortality and 568 (99%) contributed data to the analysis. 174 participants died during the 23 years of follow-up (121 in the intervention group vs 53 in the control group). Cumulative incidence of cardiovascular disease mortality was 11.9% (95% CI 8.8-15.0) in the intervention group versus 19.6% (12.9-26.3) in the control group (hazard ratio [HR] 0.59, 95% CI 0.36-0.96; p=0.033). All-cause mortality was 28.1% (95% CI 23.9-32.4) versus 38.4% (30.3-46.5; HR 0.71, 95% CI 0.51-0.99; p=0.049). Incidence of diabetes was 72.6% (68.4-76.8) versus 89.9% (84.9-94.9; HR 0.55, 95% CI 0.40-0.76; p=0.001). A 6-year lifestyle intervention programme for Chinese people with impaired glucose tolerance can reduce incidence of cardiovascular and all-cause mortality and diabetes. These findings emphasise the long-term clinical benefits of lifestyle intervention for patients with impaired glucose tolerance and provide further justification for

Jia-Yuan-Qing pill (JYQP) composed of Porcellio laevis Latreille, Corydalis Rhizoma and Radix Cynanchi Paniculati at a ratio of 9:7:7 has been found to be an effective analgesic agent. The present study aimed to evaluate the safety, addictive potential and anti-cancer pain activity of JYQP in a rat model. During the 6-month chronic toxicity test, no significant changes in general behavior, defecation, postural abnormalities, dietary or water intake or blood biochemical parameters were observed in male and female rats. Although a high dose of JYQP (5 g/kg) caused swelling of the liver, spleen and kidney in male and female rats, no pathological changes were observed in all organs examined via hematoxylin and eosin staining. The analgesic effect of JYQP on bone cancer pain was successfully confirmed in a rat model of Walker 256 cell-induced bone cancer. In contrast to morphine, in a physical dependence test, JYQP produced no withdrawal symptoms following chronic administration. The data from this study provide experimental evidence supporting the clinical use of JYQP as an effective, safe and non-addictive agent for the treatment of bone cancer pain.

Full Text Available Presently ecologicalization has become a key aspect of architecture designs. As studies deepen, the bountiful ecological ideas and design methods represented in Chinese traditional architectural culture are increasingly valued. There remain as of today quite a few residence mansions built in Ming and Qing dynasties in Yangzhou-a city famous for its history and culture. The distinctive regional culture and architectural style that those architectures embody has received worldwide attention in the academic field. By weighing on the shaping of architectural forms, choice in connection genres and structuring measures as well as sorting through and studying on the ecologicalized architectural design practices such as reemploying local materials, deeper understanding of traditional architecture will be achieved for us to better inherit and develop traditional architectural culture. Hence in-depth studies on contemporary ecological architecture and sustainable development will be of greater practical significance. Furthermore, it is beneficial to expand ideas on ecological design, truly integrate architectures into the setting to give expression to the ecological and culture features of them and provide theoretic support for creating new architecture with diversified culture implications and ecological features in light of actual conditions in an orderly manner.

In the background of the spread of western medicine into the East in the Ming and Qing Dynasties, Chinese doctors who had accepted western medicine referred to western medical knowledge and began to use the methods of anatomical observation and demonstrating to explain the objective structure of meridians and collaterals. They tried to adopt the artery and vessel explaining the shape of meridian and the blood circle and pulmonary respiration explaining the circulation of Ying-Wei. When the anatomy structures could not perfectly equal to meridians and collaterals, some doctors put forward the gasification feature of meridian to explain the reason. These results suggest that there are difference between meridians and collaterals and pure anatomy concepts, which serves as significant reference and edification for later generations.

With the development of computer technology and practical verification, digital virtual technology has matured and is increasingly being widely applied to cultural heritage protection and research. With this advancement in technology, there is pressing need to simplify heritage-related puzzles. Thus the main question that has increasingly become the most central and fundamental problem in heritage digitalization work is how to choose the "proper technology" that provides support directly, accurately and rapidly for the research, protection and exchange of cultural heritage. Based on the principles of "authenticity" and "completeness" found in the Venice Charter in regards to dealing with cultural heritage; this paper proposes the concept of the component library which facilitates the improvement and efficiency of virtual reconstruction, provides a visual discussion platform for cultural heritage protection, virtual scene construction, accuracy assessment, and multi-space-time exhibition; thereby implementing the spirit of tolerance and respect found in the Nara Document on Authenticity. The paper further aims to illustrate the significance of the Qing dynasty imperial garden architectural component library for cultural heritage study and protection, the principles for virtual library construction, use and maintenance of the library, and classification approaches, and also provide some suggestions about making high quality 3D models and effective means for database integration.

Qing-Hua Granule (QHG), the modified formulation of a classical Chinese prescription named Gegen Qinlian Decoction, was clinically employed to treat type 2 diabetes mellitus (T2DM) through regulation of glucagon-like peptide-1 (GLP-1). However, the potential mechanism is unknown. We investigate whether QHG induces GLP-1 secretion via activation of bitter taste receptor (TAS2R) pathway in the gastrointestinal tract of db/db mice. The db/db mice were intragastrically (i.g.) administered QHG (low/medium/high dose) once daily for 8 weeks. GLP-1 secretion was evaluated. The bitter receptor signaling pathway, which regulates GLP-1 secretion, including TAS2R5 (a subtype of TAS2R), α-gustducin (Gαgust), 1-phosphatidylinositol-4, 5-bisphosphate phosphodiesterase beta-2 (PLCβ2), transient receptor potential cation channel subfamily M member 5 (TRPM5), was assessed by quantitative real-time polymerase chain reaction (qRT-PCR), Western blot and immunohistochemistry (IHC). The biochemical observations of ileum and pancreas tissue were detected histopathologically. Acquity Ultra Performance LCTM - Micromass ZQ 2000 (UPLC-MS) was used for the phytochemical analysis. QHG exhibited significant and dose-dependent effect on GLP-1 secretion in db/db mice, along with significant up-regulation of TAS2R5 mRNA level and activation of TAS2R pathway (p<0.05). In addition, QHG improved the histopathological structure of ileum and pancreatic tissue. Seventeen compounds were identified in QHG. In conclusion, QHG induces GLP-1 secretion in db/db mice, most likely through the bitter taste receptor pathway. Copyright © 2017 Elsevier Masson SAS. All rights reserved.

Deviation from normal Boltzmann distribution of high-lying energy levels of iron atom excited by Okamoto-cavity microwave-induced plasmas using pure nitrogen and nitrogen–oxygen gases

International Nuclear Information System (INIS)

Wagatsuma, Kazuaki

2015-01-01

This paper describes several interesting excitation phenomena occurring in a microwave-induced plasma (MIP) excited with Okamoto-cavity, especially when a small amount of oxygen was mixed with nitrogen matrix in the composition of the plasma gas. An ion-to-atom ratio of iron, which was estimated from the intensity ratio of ion to atomic lines having almost the same excitation energy, was reduced by adding oxygen gas to the nitrogen MIP, eventually contributing to an enhancement in the emission intensities of the atomic lines. Furthermore, Boltzmann plots for iron atomic lines were observed in a wide range of the excitation energy from 3.4 to 6.9 eV, indicating that plots of the atomic lines having lower excitation energies (3.4 to 4.8 eV) were well fitted on a straight line while those having more than 5.5 eV deviated upwards from the linear relationship. This overpopulation would result from any other excitation process in addition to the thermal excitation that principally determines the Boltzmann distribution. A Penning-type collision with excited species of nitrogen molecules probably explains this additional excitation mechanism, in which the resulting iron ions recombine with captured electrons, followed by cascade de-excitations between closely-spaced excited levels just below the ionization limit. As a result, these high-lying levels might be more populated than the low-lying levels of iron atom. The ionization of iron would be caused less actively in the nitrogen–oxygen plasma than in a pure nitrogen plasma, because excited species of nitrogen molecule, which can provide the ionization energy in a collision with iron atom, are consumed through collisions with oxygen molecules to cause their dissociation. It was also observed that the overpopulation occurred to a lesser extent when oxygen gas was added to the nitrogen plasma. The reason for this was also attributed to decreased number density of the excited nitrogen species due to collisions with oxygen

从“辽燕旧界”到“华夷大界”——朝鲜人笔下的山海关意象%From "the Boundary Beween Liao and Yan" to "the Boundary Beween Hua and Yi" : Shanhaiguan as Described by Koreans in the Ming and Qing Dynasties

明朝时期，朝鲜人并无以山海关为界、关内外华夷不同的“分界”概念。但明清易代，政治局面的巨变促使朝鲜人大大地强化了华夷分界的意识，以致最终认定山海关为明晰的“界线”。具体而言，清时期朝鲜人对关内的种种自然、人文景观往往表现出令人惊叹的宽容和肯定；相反，对关外却持着过于苛刻的否定态度。然而，有趣的是，清时期朝鲜人对关内外分界意识逐渐强化之时，两地的文化差距实际上却在日益缩小。而且，关内永平府与关外辽西之间，其相似性甚至大于差异性。%The concept that Shanhaiguan was the boundary between Chinese and foreigners did not exist at all among Koreans in the Ming Dynasty, but the concept was greatly strengthened but great political changes during the Ming-Qing transition. Koreans was surprisingly tolerant and positive towards the natural and humane landscape inside the Pass, but was overly severe and negative towards the landscape outside the Pass in the Qing Dynasty. Interestingly, the cultural distinction between inside the Pass and outside the Pass was reduced day by day while the boundary conception was gradually being strengthened in the Qing Dynasty, even though the resemblance was more than the distinction between inside the Pass and outside the Pass.

The major, minor and trace elements in the bodies of ancient colored glazes which came from the site of Xiyue Temple and Lidipo kiln in Shanxi province, and were unearthed from the stratums of Song, Yuan, Ming, Early Qing and Late Qing dynasty were analyzed by instrumental neutron activation analysis (INAA). The results of multivariable statistical analyses show that the chemical compositions of the colored glaze bodies are steady from Song to Early Qing dynasty, but distinctly different from that in Late Qing. Probably, the sources of fired material of ancient colored glaze from Song to Early Qing came from the site of Xiyue Temple. The chemical compositions of three pieces of colored glazes in Ming dynasty and that in Late Qing are similar to that of Lidipo kiln. From this, authors could conclude that the sources of the materials of ancient coloured glazes of Xiyue Temple in Late Qing dynasty were fired in Lidipo kiln. (authors)

在景德镇设官监造,宋时已有,元代还成立了专门的官办监陶机构＂浮梁磁局＂。但是宋元时期监陶官的主要职责是收取地方瓷器生产税,设置目的是为了增加国家财政收入,这与明清时期御窑厂督陶官有很大不同。明清时期,朝廷在景德镇建立御窑厂,专门烧造宫廷用瓷,并委派官员督陶。督陶官作为御窑厂的直接负责人,在御器生产过程中担当着至关重要的角色,对景德镇瓷业乃至中国瓷业的发展有着重要影响。本文通过收集和整理大量的文献史料,对明清时期景德镇御窑厂督陶官及其督陶情况进行了全面梳理和比较分析,使读者对其有一个全面清晰的认识和更为深入的理解,填补了陶瓷史中这部分研究的缺漏。%The practice of assigning porcelain production supervisors in Jingdezhen started from Song Dynasty and Yuan Dynasty saw the founding of a porcelain production watchdog, namely, Fuliang Porcelain Bureau. However, the major responsibility of supervisors of Song and Yuan Dynasties was mainly to collect porcelain production taxes so as to increase the national revenue, which differed greatly from that of supervisors of Ming and Qing dynasties. During Ming and Qing Dynasties, the courts decreed to establish the Impedal Porcelain Factory in Jingdezhen to produce porcelain exclusively for imperial use and to assign supervisors for porcelain production. As the direct managers of the Imperial Porcelain Factory, these supervisors played a vital role in the production of porcelain for imperial use and in the development of the porcelain industry of Jingdezhen and that of China at large. This paper has collected and summarized a great many of documents and made a thorough and comparative analysis of all the supervisors of Ming and Qing Dynasties and their supervision so as to present readers a full, clear and better understanding of this field and to fill the gap of this field in the study

He-Ying-Qing-Re Formula (HF) was empirically modified from Si-Miao-Yong-An Decoction (SD), which was recorded in the literature of Divine Doctor's Secret Transmission, and has been utilized for centuries to treat vasculopathy through clearing heat and accelerating bloodstream. HF has been used as an effective holistic treatment of diabetic retinopathy (DR) for decades and experimentally reported to ameliorate retinal condition in diabetic mice. Our study aims to investigate the effect of HF in preventing sustained hyperglycemia and hyperlipidemia-associated retinal ganglion cell (RGC) cell death and its possible mechanism. Chromatographic fingerprint of HF was obtained upon the UPLC-based analytic system; Diabetic retinopathy was established in streptozotocin (STZ) injection-induced hyperglycemic mice; Alterations of retinal structure was assayed by H&E staining. Expression of PSD-95 and CHOP in retinae was assessed by immunofluorescence; RGC cell line (mRGC) was used for in vitro study. Cell death was analyzed by flow cytometry; Intracellular reactive oxygen species (ROS) was measured by 2',7'-dichlorofluorescin diacetate (DCFDA); Apoptosis-related proteins and signaling were monitored with immunoblotting and colorimetric assay. Chlorogenic acid, ferulic acid, and rutin were identified in HF. HF attenuates the loss of RGCs, thinning of inner retinal layers in diabetic mice. Furthermore, expressions of Brn3a and PSD-95 were restored while CHOP level was downregulated upon HF treatment. In vitro study, HF alleviates H 2 O 2 -induced apoptosis of mRGCs and loss of postsynaptic protein via scavenging ROS and suppressing ATF4/CHOP-mediated endoplasmic reticulum stress and mitochondria-related pro-apoptotic factors, probably as cleaved-caspase-3, and phospho-p38 mitogen-activated protein kinase (MARK). Meanwhile, both pro-survival protein levels like Bcl-2/Bcl-xL and postsynaptic protein of PSD-95 were upregulated upon HF treatment. HF administration was a valid

The aim of the present study was to investigate the effect of Yi Qi Qing Re Gao-containing serum (YQ-S) on rat mesangial cell (MC) proliferation and to investigate the underlying mechanism. MCs were divided into the control, lipopolysaccharide (LPS)-stimulated, YQ-S and fosinopril-containing serum (For-S) groups, and cultured for 48 h. An MTT assay was used to evaluate the proliferation of MCs. In addition, reverse transcription-quantitative polymerase chain reaction and western blot analysis were conducted to detect the expression levels of Wnt4, β-catenin and transforming growth factor (TGF)-β1 in MCs. The results indicated that YQ-S inhibited LPS-induced MC proliferation. The Wnt4 and TGF-β1 mRNA expression levels were reduced in the YQ-S group (P<0.01 or P<0.05). Furthermore, the Wnt4, β-catenin and TGF-β1 protein expression levels were suppressed in the YQ-S group (P<0.01 or P<0.05). Therefore, YQ-S appears to inhibit MC proliferation, and its mechanism may involve the inhibition of the Wnt signaling pathway and downregulation of TGF-β1 expression.

Xiao-Qing-Long-Tang (XQLT) is a classical Chinese medicine formula. It is generally used for the treatment of common cold, bronchial asthma, and allergic rhinitis in Asia. In this study, a multicomponent quantification fingerprinting approach based on ultra high performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry has been developed for the analysis of compounds in XQLT in 14.5 min. A total of 52 compounds were identified by co-chromatography of sample extract with authentic standards and comparing the retention time, UV spectra, molecular ions and characteristic fragment ions with those of authentic standards, or tentatively identified by MS(E) determination along with Mass Fragment software. Moreover, the method was validated for the simultaneous quantification of 16 components in XQLT commercial products. The method is practical for comprehensive standardization of XQLT and holistic comparison of its commercial products from different manufacturers. © 2014 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

For decades in China, the Yin-Huang-Qing-Fei capsule (YHQFC) has been widely used in the treatment of chronic bronchitis, with good curative effects. Owing to the complexity of traditional Chinese herbal formulas, the pharmacological mechanism of YHQFC remains unclear. To address this problem, a network pharmacology-based strategy was proposed in this study. At first, the putative target profile of YHQFC was predicted using MedChem Studio, based on structural and functional similarities of all available YHQFC components to the known drugs obtained from the DrugBank database. Then, an interaction network was constructed using links between putative YHQFC targets and known therapeutic targets of chronic bronchitis. Following the calculation of four topological features (degree, betweenness, closeness, and coreness) of each node in the network, 475 major putative targets of YHQFC and their topological importance were identified. In addition, a pathway enrichment analysis based on the Kyoto Encyclopedia of Genes and Genomes pathway database indicated that the major putative targets of YHQFC are significantly associated with various pathways involved in anti-inflammation processes, immune responses, and pathological changes caused by asthma. More interestingly, eight major putative targets of YHQFC (interleukin [IL]-3, IL-4, IL-5, IL-10, IL-13, FCER1G, CCL11, and EPX) were demonstrated to be associated with the inflammatory process that occurs during the progression of asthma. Finally, a molecular docking simulation was performed and the results exhibited that 17 pairs of chemical components and candidate YHQFC targets involved in asthma pathway had strong binding efficiencies. In conclusion, this network pharmacology-based investigation revealed that YHQFC may attenuate the inflammatory reaction of chronic bronchitis by regulating its candidate targets, which may be implicated in the major pathological processes of the asthma pathway.

Qing Ye Dan (QYD) is the whole plant of Swertia mileensis and used in Chinese folk medicine for the treatment of prostatitis, benign prostatic hyperplasia (BPH) and so on. This study was to investigate the effects of QYD and its main component swertiamarin on BPH induced by testosterone in rats. The prostatic expressions of vascular endothelial growth factor (VEGF), epidermal growth factor (EGF), basic fibroblast growth factor (βFGF) and proliferating cell nuclear antigen (PCNA) were detected by immunohistochemistry assay. Prostatic levels of oxidative stress and inflammatory-related factors were also analyzed. Additionally, the prostatic expressions of androgen receptor (AR), estrogen receptor (ER)-α, ER-β, hypoxia-inducible factor (HIF)-1α, B-cell CLL/lymphoma (Bcl)-2 and Bcl-2-associated X protein (Bax) were measured by western blot. The epithelial-mesenchymal transition (EMT) associated factors were evaluated by quantitative RT-PCR. It showed that QYD and swertiamarin ameliorated the testosterone-induced prostatic hyperplasia and collagen deposition, attenuated the over-expressions of HIF-1α, VEGF, EGF, βFGF, PCNA, AR and ER-α, reduced the ratio of Bcl-2/Bax, enhanced the expression of ER-β, inhibited the oxidative stress and local inflammation, as well as relieved prostatic EMT. It suggested that QYD and swertiamarin had prostatic protective potential against BPH. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

Modeling estimates of the effect of acid rain on background radiation dose.

Acid rain causes accelerated mobilization of many materials in soils. Natural and anthropogenic radionuclides, especially 226Ra and 137Cs, are among these materials. Okamoto is apparently the only researcher to date who has attempted to quantify the effect of acid rain on the "background" radiation dose to man. He estimated an increase in dose by a factor of 1.3 following a decrease in soil pH of 1 unit. We reviewed literature that described the effects of changes in pH on mobility and plant uptake of Ra and Cs. Generally, a decrease in soil pH by 1 unit will increase mobility and plant uptake by factors of 2 to 7. Thus, Okamoto's dose estimate may be too low. We applied several simulation models to confirm Okamoto's ideas, with most emphasis on an atmospherically driven soil model that predicts water and nuclide flow through a soil profile. We modeled a typical, acid-rain sensitive soil using meteorological data from Geraldton, Ontario. The results, within the range of effects on the soil expected from acidification, showed essentially direct proportionality between the mobility of the nuclides and dose. This supports some of the assumptions invoked by Okamoto. We conclude that a decrease in pH of 1 unit may increase the mobility of Ra and Cs by a factor of 2 or more. Our models predict that this will lead to similar increases in plant uptake and radiological dose to man. Although health effects following such a small increase in dose have not been statistically demonstrated, any increase in dose is probably undesirable.

This supports some of the assumptions invoked by Okamoto. We conclude that a decrease in pH of 1 unit may increase the mobility of Ra and Cs by a factor of 2 or more. Our models predict that this will lead to similar increases in plant uptake and radiological dose to man. Although health effects following such a small increase in dose have not been statistically demonstrated, any increase in dose is probably undesirable

Full Text Available Refined Qing-Kai-Ling (QKL, a modified Chinese medicine, consists of three main ingredients (Baicalin, Jasminoidin and Desoxycholic acid, plays a synergistic effect on the treatment of the acute stage of ischemic stroke. However, the rules of the combination and synergism are still unknown. Based on the ischemic stroke mice model, all different kinds of combination of Baicalin, Jasminoidin, and Desoxycholic acid were investigated by the methods of neurological examination, microarray, and genomics analysis. As a result, it confirmed that the combination of three drugs offered a better therapeutical effect on ischemic stroke than monotherapy of each drug. Additionally, we used Ingenuity pathway Analysis (IPA and principal component analysis (PCA to extract the dominant information of expression changes in 373 ischemia-related genes. The results suggested that 5 principal components (PC1-5 could account for more than 95% energy in the gene data. Moreover, 3 clusters (PC1, PC2+PC5, and PC3+PC4 were addressed with cluster analysis. Furthermore, we matched PCs on the drug-target networks, the findings demonstrated that Baicalin related with PC1 that played the leading role in the combination; Jasminoidin related with PC2+PC5 that played a compensatory role; while Desoxycholic acid had the least performance alone which could relate with PC3+PC4 that played a compatible role. These manifestations were accorded with the principle of herbal formulae of Traditional Chinese Medicine (TCM, emperor-minister-adjuvant-courier. In conclusion, we firstly provided scientific evidence to the classic theory of TCM formulae, an initiating holistic viewpoint of combination therapy of TCM. This study also illustrated that PCA might be an applicable method to analyze the complicated data of drug combination.

Cadmium (Cd) is an environmental pollutant with reproductive toxicity. Swertia mileensis is used in Chinese medicine for the treatment of prostatic deficits and named as Qing Ye Dan (QYD). This study was undertaken to investigate the potential protective effects of QYD against Cd-induced prostatic deficits. Rat model of prostatic deficits was induced by 0.2 mg/kg/d CdCl2 subcutaneous injection for 15 days. The prostatic oxidative stress was evaluated by detecting the levels of malondialdehyde, nitric oxide, reduced/ oxidized glutathione, total sulfhydryl groups and enzymatic antioxidant status. The prostatic inflammation was estimated by testing the levels of pro-inflammatory cytokines. The levels of epithelial-mesenchymal transition (EMT) markers E-cadherin, fibronectin, vimentin and α-smooth muscle actin were measured by qPCR analysis. Additionally, the prostatic expressions of transforming growth factor-β1 (TGF-β1), type I TGF-β receptor (TGF-βRI), Smad2, phosphorylation-Smad2 (p-Smad2), Smad3, p-Smad3, Smad7, nuclear related factor-2 (Nrf-2), heme oxygenase-1 (HO-1), B-cell CLL/lymphoma (Bcl)-2 and Bcl-2-associated X protein (Bax) were measured by western blot assay. It was found that QYD ameliorated the Cd-induced prostatic oxidative stress and inflammation, attenuated prostatic EMT, inhibited the TGF-β1/Smad pathway, increased Bcl-2/Bax ratio and enhanced the activity of Nrf-2/HO-1 pathway. These results showed that QYD could ameliorate Cd-induced prostatic deficits via modulating Nrf-2/HO-1 and TGF-β1/Smad pathways. © 2017 The Author(s). Published by S. Karger AG, Basel.

Xiao-Qing-Long-Tang shows preventive effect of asthma in an allergic asthma mouse model through neurotrophin regulation

Science.gov (United States)

2013-01-01

Background This study investigates the effect of Xiao-Qing-Long-Tang (XQLT) on neurotrophin in an established mouse model of Dermatophagoides pteronyssinus (Der p)-induced acute allergic asthma and in a LA4 cell line model of lung adenoma. The effects of XQLT on the regulation of nerve growth factor (NGF) and brain-derived neurotrophic factor (BDNF), airway hyper-responsiveness (AHR) and immunoglobulin E were measured. Methods LA4 cells were stimulated with 100 μg/ml Der p 24 h and the supernatant was collected for ELISA analysis. Der p-stimulated LA4 cells with either XQLT pre-treatment or XQLT co-treatment were used to evaluate the XQLT effect on neurotrophin. Balb/c mice were sensitized on days 0 and 7 with a base-tail injection of 50 μg Dermatophagoides pteronyssinus (Der p) that was emulsified in 50 μl incomplete Freund’s adjuvant (IFA). On day 14, mice received an intra-tracheal challenge of 50 μl Der p (2 mg/ml). XQLT (1g/Kg) was administered orally to mice either on days 2, 4, 6, 8, 10 and 12 as a preventive strategy or on day 15 as a therapeutic strategy. Results XQLT inhibited expression of those NGF, BDNF and thymus-and activation-regulated cytokine (TARC) in LA4 cells that were subjected to a Der p allergen. Both preventive and therapeutic treatments with XQLT in mice reduced AHR. Preventive treatment with XQLT markedly decreased NGF in broncho-alveolar lavage fluids (BALF) and BDNF in serum, whereas therapeutic treatment reduced only serum BDNF level. The reduced NGF levels corresponded to a decrease in AHR by XQLT treatment. Reduced BALF NGF and TARC and serum BDNF levels may have been responsible for decreased eosinophil infiltration into lung tissue. Immunohistochemistry showed that p75NTR and TrkA levels were reduced in the lungs of mice under both XQLT treatment protocols, and this reduction may have been correlated with the prevention of the asthmatic reaction by XQLT. Conclusion XQLT alleviated allergic inflammation including AHR, Ig

OBJECTIVE Despite its growing prevalence in China, the extent to which diabetes leads to excess cardiovascular disease (CVD) mortality and all-cause mortality is unclear. RESEARCH DESIGN AND METHODS We compared death rates and causes of death among 630 people with newly diagnosed diabetes (NDD) and 519 with normal glucose tolerance (NGT) who, in 1986, were identified as a result of screening 110,660 adults aged 25–74 years for diabetes in Da Qing, China. RESULTS During 23 years of follow-up, 338 (56.5%) participants with NDD and 100 (20.3%) with NGT died. CVD was the predominant cause of death in those with diabetes (47.5% in men and 49.7% in women), almost half of which was due to stroke (52.3% in men and 42.3% in women). The age-standardized incidence of all-cause death was three times as high in those with NDD as in those with NGT with incidences (per 1,000 person-years) of 36.9 (95% CI 31.5–42.3) vs. 13.3 (10.2–16.5) in men (P < 0.0001) and 27.1 (22.9–31.4) vs. 9.2 (7.8–10.6) in women (P < 0.0001). The incidence of CVD deaths in men and women with NDD (17.5 [13.8–21.2] vs. 13.5 [10.5–16.5]) did not differ significantly. Significantly higher death rates attributable to renal disease and infection were also found in the NDD group. CONCLUSIONS Diabetes is associated with a substantially increased risk of death in Chinese adults, especially from CVD, almost half of which is due to stroke. PMID:25887356

In this book, Pae Usŏng, a historian at the University of Seoul, takes a fresh look at the relationship of Chosŏn Korea (1392–1910 with China and that of Chosŏn’s yangban (scholar-officials with Sinitic civilization as a whole. None of Chosŏn’s relationships were more important, or more complicated, than that with China. On the one hand, Chosŏn was in nearly all respects independent from both Ming (1368–1644 and Qing (1644–1912 China. On the other hand, under both the Ming and the Qing, the Chosŏn court sent envoys regularly to Beijing, thereby acknowledging its subservience to China. After the Manchu Qing supplanted the Ming in the mid-eighteenth century, most Chosŏn officials, privately at least, rejected the Qing as an empire controlled by barbarians. Following the Qing conquest, most Chosŏn scholar-officials also asserted that China’s cultural and political traditions had been irreparably lost within China proper, and that Chosŏn was the only remaining heir of the Sinitic tradition. Even so, no Chosŏn person of significance before the late nineteenth century actually called for the removal of Chosŏn from the Sinitic world, no matter how much the legitimacy of the Qing was doubted...

Recurrent cardiovascular event remains high in stable coronary artery disease (SCAD), especially in patients with multiple risk factors, despite a high rate of use conventional treatment. Traditional Chinese Medicine (TCM) is a promising complementary and alternative medicine for treating SCAD, while evidence for its effect on long-term survival is limited. This study was designed to test if Chinese herbal medicine in addition to conventional treatment is more effective than conventional treatment alone in reducing major adverse cardiac event (MACE) for SCAD patients with multiple risk factors during a 1-year follow-up. This is a multicenter, placebo-controlled, double-blinded, randomized controlled clinical trial. A total of 1500 patients are randomized in a 1:1 ratio to receive the Qing-Xin-Jie-Yu Granules (QXJYG) or the placebo granules, twice daily for 6 months. The primary outcome is the combined outcomes including cardiac death, nonfatal myocardial infarction and revascularization. The secondary outcome is the combined outcomes including all-cause mortality, re-admission for acute coronary syndrome (ACS), heart failure, malignant supraventricular and ventricular arrhythmia influencing hemodynamics, ischemic stroke, and other thromboembolic events during 1-year follow-up. The assessment is performed at baseline (before randomization), 1, 3, 6, 9, and 12 months after randomization. This is the first multicenter trial sponsored by the national funding of China to evaluate TCM in combination with conventional treatment on 1-year survival in high-risk SCAD patients. If successful, it will provide an evidence-based complementary therapeutic approach for reducing MACE from SCAD. The trial was registered in the Chinese Clinical Trial Registry on December 28, 2013. The registration number is ChiCTR-TRC-13004370 .

Pitchfork, firstly appeari ng in Wangzhen Agriculture Books, was distributed around the southern region of the Korean peninsula since the 2nd century BC and from there went over to China before the Tang dynasty. This is far different in production technique from the pitchfork of China after the Yuan dynasty, and the production technique and the shape of the pitchfork of the Korean peninsula in those days are still continuing up to this time. There are multiple factors in the widespread distribution of pitchfork in Jiangnan re- gion. Before anything else, the change in social circumstances of the Ming and Qing dynasties decreased the household landholding area and increased the production of commercial crops and the chances for employed labor. It therefore provided for the conditions to supplement the loss from the failure to use cattle ploughing and to compensate the labor productivity of hoes with the mutually-aided farming. The paddy fields＇ strong clay soil also made it unsuitable to introduce the ploughs from Jiangdong. In the farming in Jiangnan of the Ming and Qing dynasties, as a result, the pitchfork came to establish itself as a main farming tool for the deep ploughing and heavy fertilizer.%铁搭是具有2—4个铁齿的耕地专用农具，是一种为江南水田的深耕起到决定性作用的代耕用具。本文论证铁搭在唐朝时期由韩半岛的济州岛传播到中国的过程。明清时代的铁搭可与江东犁媲美，它时于引领江南农业经济发展所起的实质性作用是功不可没的。而韩半岛南部则早在一世纪起就已出现铁搭，因为和汉魏王朝的交易活跃的原因，铁搭虽然有很早传来的可能性，但根据在北宋时期扬州的铁搭形态上猜测，比起三韩时代，三国时代（韩）即中国唐代之前传来的可能性更高。

Related key attacks (RKAs) are powerful cryptanalytic attacks where an adversary can change the secret key and observe the effect of such changes at the output. The state of the art in RKA security protects against an a-priori unbounded number of certain algebraic induced key relations, e.......g., affine functions or polynomials of bounded degree. In this work, we show that it is possible to go beyond the algebraic barrier and achieve security against arbitrary key relations, by restricting the number of tampering queries the adversary is allowed to ask for. The latter restriction is necessary......-protocols (including the Okamoto scheme, for instance) are secure even if the adversary can arbitrarily tamper with the prover’s state a bounded number of times and obtain some bounded amount of leakage. Interestingly, for the Okamoto scheme we can allow also independent tampering with the public parameters. We show...

Aquaporin-1 (AQP-1) is expressed in lung endothelial cells and regulates water transport; thus, AQP-1 plays an important role in a number of edema-associated lung diseases. Qing Yin Tang (QYT), a traditional Chinese medicine, has been shown to effectively reduce the mortality rate of acute lung injury (ALI) induced by severe acute pancreatitis (SAP). The current study aimed to investigate the detailed mechanisms underlying the effects of QYT on ALI induced by SAP, particularly the effects on the expression levels of AQP-1 in the lung tissue. ALI was established in Wister rats who were subsequently divided into four groups: SHAM, ALI, dexamethasone (DEX) and QYT groups (n=8 per group). In the QYT group, 20 ml/kg QYT was administered by gavage immediately following the induction of SAP. Blood and lung tissues were collected 8 h following the induction of pancreatitis. The lung wet/dry ratio, as well as the levels of blood gases, serum amylase and tumor necrosis factor-α (TNF-α), were measured at 4, 8 and 12 h following SAP-associated ALI induction surgery. The expression levels of AQP-1 in the lung tissue were detected by quantitative polymerase chain reaction, immunohistochemistry and western blot analysis. No statistically significant differences were observed with regard to the levels of serum amylase, wet/dry ratio, partial pressure of oxygen, serum TNF-α and pathological changes in the pulmonary tissue between the QYT and DEX groups; however, a statistically significant difference was observed when compared with the ALI group. The expression levels of AQP-1 significantly increased (P<0.05) and lung edema was alleviated in the QYT and DEX groups, when compared with ALI group. Therefore, the expression level of AQP-1 is associated with pulmonary edema. QYT protects the lungs from injury induced by SAP via the upregulation of AQP-1, which suppresses TNF-α expression.

Background The association between hyperinsulinemia and obesity is well known. However, it is uncertain especially in childhood obesity, if initial fasting hyperinsulinemia predicts obesity, or obesity leads to hyperinsulinemia through insulin resistance. Objective To investigate the predictive effect of fasting plasma insulin on subsequent weight change after a 5-year interval in childhood. Methods 424 Children from Da Qing city, China, were recruited at 5 years of age and followed up for 5 years. Blood pressure, anthropometric measurements, fasting plasma insulin, glucose and triglycerides were measured at baseline and 5 years later. Results Fasting plasma insulin at 5 years of age was significantly correlated with change of weight from 5 to 10 years (ΔWeight). Children in the lowest insulin quartile had ΔWeight of 13.08±0.73 kg compare to 18.39±0.86 in the highest insulin quartile (P<0.0001) in boys, and similarly 12.03±0.71 vs 15.80±0.60 kg (P<0.0001) in girls. Multivariate analysis showed that the predictive effect of insulin at 5 years of age on subsequent weight gain over 5 years remained statistically significant even after the adjustment for age, sex, birth weight, TV-viewing time and weight (or body mass index) at baseline. By contrast, the initial weight at 5 years of age did not predict subsequent changes in insulin level 5 years later. Children who had both higher fasting insulin and weight at 5 years of age showed much higher levels of systolic blood pressures, fasting plasma glucose, the homeostasis model assessment for insulin resistance (HOMA-IR) and triglycerides at 10 years of age. Conclusions Fasting plasma insulin at 5 years of age predicts weight gain and cardiovascular risk factors 5 year later in Chinese children of early childhood, but the absolute weight at 5 years of age did not predict subsequent change in fasting insulin.

Global climate change in the form of extreme, variation, and short- or mid-term fluctuation is now widely conceived to challenge the survival of the human beings and the societies. Meanwhile, improving present and future climate modeling needs a comprehensive understanding of the past climate patterns. Although historical climate modeling has gained substantive progress in recent years based on the new findings from dynamical meteorology, phenology, or paleobiology, less known are the mid- to short-term variations or lower-frequency variabilities at different temporal scale and their regional expressions. Enabling accurate historical climate modeling would heavily rely on the robustness of the dataset that could carry specific time, location, and meteorological information in the continuous temporal and spatial chains. This study thus presents an important methodological innovation to reconstruct historical climate modeling at multiple temporal and spatial scales through building a historical climate dataset, based on the Chinese chronicles compiled in a Zhang (2004) edited Compendium of Chinese Meteorological Records of the Last 3,000 Years since Zhou Dynasty (1100BC). The dataset reserves the most delicate meteorological data with accurate time, location, meteorological event, duration, and other phonological, social and economic impact information, and is carefully digitalized, coded, and geo-referenced on the Geographical Information System based maps according to Tan's (1982) historical atlas in China. The research project, beginning in January 2015, is a collaborative work among scholars across meteorology, geography, and historical linguistics disciplines. The present research findings derived from the early 100+ years of the Qing dynasty include the following. First, the analysis is based on the sampling size, denoted as cities/counties, n=1398 across the Mainland China in the observation period. Second, the frequencies of precipitation, cold

Full Text Available For decades, historians defined the ukanju, also known as taoren (逃人 in the Chinese-language archives of the Qing Dynasty (1644–1911A.C., as the Manchu’s ethnic Han-Chinese slaves or escapees. However, this definition fails to explain why ukanju served as the catalyst for the Manchu invasions of Chosŏn in 1627 and 1636 and why so many ukanju with considerable ethnic diversity emerged in the first half of the 17th century. Also, the question of what roles the ukanju played in the Ming-Qing transition (1616–1644 A.C. is still unexplored. In this essay, I will redefine ukanju as, rather than merely slaves, a person or group of people who fled from their own country to another place (or crossed the borders. I will also point out the overlooked relationship between the ukanju and the transition of the political order in Northeastern Asia during the 17th century – including the reversal of outcomes in battles between the Qing and the Ming, the legal shift regarding state boundaries and the act of fleeing in the Chosŏn legal code. To achieve this goal, I will utilize Manchu archives as well as Qing and Chosŏn archives written in classical Chinese as the main sources of this essay. This study, therefore, contributes to Korean and Chinese history, international relations in pre-modern Northeastern Asia, and Manchu studies.

The response of purifying capability, enzyme activity, nitrification potentials, and total number of bacteria in the rhizosphere in December to wetland plants, substrates, and earthworms was investigated in integrated vertical flow constructed wetlands (IVFCW). The removal efficiency of total nitrogen (TN), NH4-N, chemical oxygen demand (COD), and total phosphorus (TP) was increased when earthworms were added into IVFCW. A significantly average removal efficiency of N in IVFCW that employed river sand as substrate and in IVFCW that employed a mixture of river sand and Qing sand as substrate was not found. However, the average removal efficiency of P was higher in IVFCW with a mixture of river sand and Qing sand as substrate than in IVFCW with river sand as substrate. Invertase activity in December was higher in IVFCW that used a mixture of river sand and Qing sand as substrate than in IVFCW which used only river sand as substrate. However, urease activity, nitrification potential, and total number of bacteria in December was higher in IVFCW that employed river sand as substrate than in IVFCW with a mixture of river sand and Qing sand as substrate. The addition of earthworms into the integrated vertical flow constructed wetland increased the above-ground biomass, enzyme activity (catalase, urease, and invertase), nitrification potentials, and total number of bacteria in December. The above-ground biomass of wetland plants was significantly positively correlated with urease and nitrification potentials (p earthworms into IVFCW increased enzyme activity and nitrification potentials in December, which resulted in improving purifying capability.

Qing brick tea (QBT), traditional and popular beverage for Chinese people, is an important post-fermentation dark tea. Our present study was performed to investigate the ameliorative effects of QBT aqueous extract on metabolic syndrome (Mets) in monosodium glutamate-induced obese mice and the potential mechanisms. Monosodium glutamate-induced obese mice were used to evaluate the anti-Mets effects of QBT. Content levels of malonaldehyde (MDA), reactive oxygen species (ROS) and protein carbonylation, antioxidant enzyme activities of superoxide dismutase (SOD), glutathione peroxidase (GPx), catalase (CAT), glutathione reductase (GR) in the skeletal muscle were assessed by commercial kits, respectively. Western blot and Q-PCR were used to detect the expressions of Transcription Factor Nuclear Factor-Erythroid 2-Related Factor 2 (Nrf2) signaling pathway and downstream antioxidant factors. In addition, activity of AKT signaling and expression of glucose transporter type 4 (GLUT4) in the skeletal muscle were investigated by western blot. QBT treatment limited gain of body weight, waistline and LEE index, improved insulin resistance and glucose intolerance, reduced lipid level in MSG mice. Content levels of MDA, ROS and protein carbonylation in skeletal muscle of QBT group were significantly improved compared to those of MSG mice. The antioxidant enzyme activities of SOD, GPx, CAT, and GR were increased in skeletal muscle of MSG mice intervened with QBT. After 20-week QBT treatment, Nrf2 signaling pathway and downstream antioxidant factors were both increased in the skeletal muscle. In addition, QBT treatment improved insulin signaling by preferentially augmenting AKT signaling, as well as increased the protein expression of GLUT4 in the skeletal muscle. Our results showed that QBT intake was effective in protecting monosodium glutamate-induced obese mice against metabolic syndrome and involved in the Nrf2 signaling pathway in the skeletal muscle.

Temperature and water potential for germination based on the thermal and hydrotime models have been successfully applied in predicting germination requirements of physiologically dormant seeds as well as nondormant seeds. However, comparative studies of the germination requirements of physically dormant seeds from different ecosystems have not been done. Germination of scarified seeds of four legume species collected from the Qing-Tibetan Plateau and of four collected in the Alax Desert in China was compared over a range of temperatures and water potentials based on thermal time and hydrotime models. Seeds of species from the Qing-Tibetan Plateau had a lower base temperature (T b) and optimal temperature (T o) for germination than those from the Alax Desert. Seeds of the four species from the Qing-Tibetan Plateau germinated to high percentages at 5°C, whereas none of the four desert species did so. Seeds of species from the Alax Desert germinated to a high percentage at 35°C or 40°C, while no seeds of species from the Qing-Tibetan Plateau germinated at 35°C or 40°C. The base median water potential [Ψ b(50)] differed among species but not between the two habitats. The thermal time and hydrotime models accurately predicted the germination time course of scarified seeds of most of the eight species in response to temperature and water potential; thus, they can be useful tools in comparative studies on germination of seeds with physical dormancy. Habitat temperatures but not rainfall is closely related to germination requirements of these species. © 2015 Botanical Society of America, Inc.

Interlopers at the Fringes of Empire: The Procurators of the Propaganda Fide Papal Congregation in Canton and Macao, 1700-1823

Directory of Open Access Journals (Sweden)

Eugenio Menegon

2017-12-01

Full Text Available The office of the procurator of the papal Sacred Congregation for the Propagation of the Faith (Sacra Congregatio de Propaganda Fide offers a unique case study of noncommercial interloping in the long eighteenth century in the Pearl River Delta, and reveals the complexity and fluidity of life at the intersection of Asian and European maritime environments in that special human ecosystem. The oceanic infrastructure of the Age of Sail and the Sino-Western trade system in Canton sustained the Catholic missionary enterprise in Asia, and the professional figure of the procurator represented its economic and political linchpin. Procurators were agents connected with both European and Qing imperial formations, yet not directly at their service. They utilized existing maritime trade networks to their own advantage without being integral parts of those networks’ economic mechanisms. All the while, they subverted Qing prohibitions against Christianity. Using sources preserved in Rome, this article offers new insights into the global mechanisms of trade, communication, and religious exchange embodied by the procurators-interlopers and their networks, with significant implications for the history of the Sino-Western trade system, Qing policies toward the West and Christianity, and the history of Asian Catholic missions.

The Game People Played: Mahjong in Modern Chinese Society and Culture

Maggie Green

2015-12-01

Full Text Available This article considers the discourse surrounding the popular Chinese table game of mahjong in the nineteenth and twentieth centuries, using it as a barometer to trace social and cultural changes during the late Qing and Republican periods. After analyzing the connection between mahjong; its forerunner, madiao; and their antithesis, weiqi (go, it traces the changing position of mahjong in Chinese society from a game seemingly loathed by literati to a staple of bourgeois parlors. Drawing on a variety of journals, newspapers, and visual sources, the article further explores culture from class and gender perspectives in the late Qing and Republican periods, as mahjong moved from a visibly male activity to one largely associated with women. Finally, it considers the relationship between games and discourses of modernity, and the important changes taking place regarding leisure time in the twentieth century. The article argues that mahjong has been uniquely resistant to regulation and control. Enjoyment of the game spread across class and gender lines, despite the efforts of reformers, for reasons that reflect and embody key shifts from the late Qing dynasty through the end of the Republican period.

The history of the artemisinins from Ge Hong in China during the 4th century, to the re-discovery of the qing hao derivatives in the 1970s, to the explosion of artemisinin derivatives and combinations throughout the world today is a fascinating story. The central and underappreciated role of the United States Army's 'drug company' known as the Division of Experimental Therapeutics at the Walter Reed Army Institute of Research is a story worth relating. From being the first group outside China to extract the active component of qing hao, to leading the work on neurotoxicity of the class in animals, to bringing a Good Manufacturing Practices intravenous formulation to the worldwide market is traced.

Memory Politics at Work in a Gyalrong Revolt in the Early Twentieth Century

Directory of Open Access Journals (Sweden)

Tenzin Jinba

2016-06-01

Full Text Available A 1917 uprising led by Zöpa, a low-ranking monk who proclaimed himself emperor, attracted over four thousand participants in the Gyalrong region on the southeastern edge of the Tibetan Plateau. Some of the uprising’s agendas and goals contradicted one another. It targeted the Han with the shout of “Crush the Great Han,” even though Zöpa’s two main henchmen were Han. It evoked the support of a wider Gyalrong community and claimed to avenge Qing oppression (since the Jinchuan campaigns of the eighteenth century while attempting to establish a Qing-branded kingdom. Also, this revolt targeted foreign intrusion, as evidenced by the burning of a Catholic church in Danba. This article offers a glimpse into how this uprising was embedded in sociopolitical changes during a critical transitional period from the Qing to the Republic in Sichuan’s Sino-Tibetan borderlands. It particularly examines how memories of the Qing’s atrocities and subsequent reforms, as well as of the “golden past” of Gyalrong, catalyzed ethnic and religious tensions. Above all, this study exemplifies the significance of integrating historical analyses with ethnographic investigations by examining the ways in which written documents and oral histories constitute competing yet complementary interpretive narratives about sociopolitical changes.

Zhengleibencao (Classified Materia Medica) had been formed into several kinds of edition systems during its dissemination, among which there was the edition system of Daquanbencao (Complete Collection of Materia Medica). Daquanbencao was originally carved in the Jin dynasty, thereafter it was re-carved in the Yuan, Ming and Qing dynasties so as to form a series of editions such as the edition of Zhenyou in the second year of the Jin dynasty; the edition of the Zongwenshuyuan college in Dade renyan year of the Yuan dynasty; the WANG Qiu's carved edition of Shangyitang hall in the Ming dynasty; the carved edition of Jishanshuyuan, the Jishang mountain college in the Ming dynasty, the reprinted edition of PENG Duan-wu in the Ming dynasty, the supplementary edition of YANG Bi-da in the Qing dynasty;, and the carved edition of KE Feng-shi in the Qing dynasty. Among all the editions, Chongkanjingshizhengleidaquanbencao (Reprinted Classified Daquan Materia Medica from Historical Classics) was the representative one. As a representative of the above editions, the carved edition of WANG took the edition of the Zongwenshuyuan college of the Yuan dynasty as the original edition, but the images picture of materia medica adopted from the edition of Zhenghebencao (Materia Medica of the Zhenghe era).

Full Text Available Abstract:             This article examines the literary garden depicted by Pu Songling (1640-1715 in his' Liaozhai zhiyi '聊齋誌異 (Liaozhai's records of the strange; 1766. These enchanted, deserted, and haunted gardens function as metaphors for the contested ground on which some key Ming-Qing intellectual issues are debated. The article examines Pu’s depiction of 'qing'情,an important concept reflecting the philosophical and literary trends of the time, and shows that in the process of constructing literary gardens, Pu challenges the intellectual issues of his time and dissolves the boundaries between normal and abnormal, reality and ideal, death and life, and order and disorder.

Does the sex ratio at sexual maturity affect men's later-life mortality risks? Evidence from historical China.

Science.gov (United States)

Zang, Emma; Zheng, Hui

2018-04-01

This study examines the relationship between the male-to-female sex ratio (measured as the proportion male) at sexual maturity and later-life mortality risks in the context of pre-industrial northeast China, using registration data from the Qing Dynasty. We find that a higher male-to-female sex ratio at sexual maturity is associated with a higher later-life mortality risk among men. This association is likely due to the long-term adverse consequences of stress caused by low mate availability at sexual maturity. We further find that a high sex ratio at sexual maturity mitigates the health benefits of marriage and exacerbates the health disadvantages of holding an official position in Qing China.

Directory of Open Access Journals (Sweden)

Login Lok-yin Law

2015-08-01

Full Text Available In the 18th century Chosŏn (1392-1910, some scholars, such as Hong Tae-yong (1731-1783 advocated that Chosŏn should learn the advantages of the Qing (1644-1912 society to reform the social structure and government of Chosŏn. The school of these advocates has been known as Pukhak by historians. The intellectual factors of the school of Pukhak’s formation and development have been overlooked by the academia of Chosŏn intellectual history. In fact, Pukhak was closely related to the idea of the school of Nakhak which believed that nature of things was equivalent to humans. Kim Wŏn-haeng, was one of the supporters of Nakhak and Hong Tae-yong was one of the students of Kim. Hong’s thought and writing exposed that his thought was profoundly influenced by Kim Wŏn-haeng. Hong was deemed to be the first prominent scholar of the Pukhak School during the 18th century Chosŏn. Hong and other scholars of Pukhak advocated learning the new knowledge from Qing China even though it was a barbarian society. Therefore, this paper will investigate the intellectual relationships between Hong Tae-yong and Kim Wŏn-haeng to reveal how intellectuals of Nakhak shaped the formation of Pukhak School and exposed the idea of learning from Qing China.

Microarray studies on lager brewer's yeasts reveal cell status in the process of autolysis.

Science.gov (United States)

Xu, Weina; Wang, Jinjing; Li, Qi

2014-08-01

In this work, we performed DNA microarray studies on lager brewer's yeast Saccharomyces pastorianus to investigate changes in gene expression in the process of autolysis. The two strains we used were Qing2 and 5-2. Strain 5-2 is a mutant of Qing2 and autolyzes much more slowly than its parent strain. Four samples of these two strains during different autolysis stages (0% and 15%) were tested using DNA microarray containing > 10,000 yeast's genes. Analysis of genes with the same transcription pattern (up- or down-regulated in both strains) showed that the same 99 genes were up-regulated (transcription levels were increased), and the same 97 genes were down-regulated (transcription levels were decreased) by fivefold or more during autolysis. Genes involved in energy production/utilization, protein anabolism, and stress response were down-regulated. Genes related to cell wall organization and biogenesis, starvation response and DNA damage response were up-regulated. Analysis of genes with opposite transcription patterns (up-regulated in one strain and down-regulated in the other one) showed that 246 genes were up-regulated in 5-2 (autolyzes slowly) and down-regulated in Qing2 (autolyzes rapidly). Another 18 genes had opposite transcription levels, indicating that the strain which autolyzes slowly had better cell vitality despite the same autolysis stage. These findings might further promote the global understanding of autolysis in yeast. © 2014 Federation of European Microbiological Societies. Published by John Wiley & Sons Ltd. All rights reserved.

Comparative study on contribution of charge-transfer collision to excitations of iron ion between argon radio-frequency inductively-coupled plasma and nitrogen microwave induced plasma

Energy Technology Data Exchange (ETDEWEB)

Satoh, Kozue; Wagatsuma, Kazuaki, E-mail: wagatuma@imr.tohoku.ac.jp

2015-06-01

This paper describes an ionization/excitation phenomenon of singly-ionized iron occurring in an Okamoto-cavity microwave induced plasma (MIP) as well as an argon radio-frequency inductively-coupled plasma (ICP), by comparing the Boltzmann distribution among iron ionic lines (Fe II) having a wide range of the excitation energy from 4.76 to 9.01 eV. It indicated in both the plasmas that plots of Fe II lines having lower excitation energies (4.76 to 5.88 eV) were fitted on each linear relationship, implying that their excitations were caused by a dominant thermal process such as collision with energetic electron. However, Fe II lines having higher excitation energies (more than 7.55 eV) had a different behavior from each other. In the ICP, Boltzmann plots of Fe II lines assigned to the higher excited levels also followed the normal Boltzmann relationship among the low-lying excited levels, even including a deviation from it in particular excited levels having an excitation energy of ca. 7.8 eV. This deviation can be attributed to a charge-transfer collision with argon ion, which results in the overpopulation of these excited levels, but the contribution is small. On the other hand, the distribution of the high-lying excited levels was non-thermal in the Okamoto-cavity MIP, which did not follow the normal Boltzmann relationship among the low-lying excited levels. A probable reason for the non-thermal characteristics in the MIP is that a charge-transfer collision with nitrogen molecule ion having many vibrational/rotational levels could work for populating the 3d{sup 6}4p (3d{sup 5}4s4p) excited levels of iron ion broadly over an energy range of 7.6–9.0 eV, while collisional excitation by energetic electron would occur insufficiently to excite these high-energy levels. - Highlights: • This paper describes the excitation mechanism of iron ion in Okamoto-cavity MIP in comparison with conventional ICP. • Boltzmann distribution is studied among iron ionic lines of

2007-01-01

A method for finding relations of roots of polynomials is presented. Our approach allows us to get a number of relations between the zeros of the classical polynomials as well as the roots of special polynomials associated with rational solutions of the Painleve equations. We apply the method to obtain the relations for the zeros of several polynomials. These are: the Hermite polynomials, the Laguerre polynomials, the Yablonskii-Vorob'ev polynomials, the generalized Okamoto polynomials, and the generalized Hermite polynomials. All the relations found can be considered as analogues of generalized Stieltjes relations

Petrological-geochemical characteristics of coarse-grained clastic sedimentary rocks of Quantou Formation, Cretaceous in Songliao basin and their geological significance

International Nuclear Information System (INIS)

Wang Gan; Zhang Bangtong

2005-01-01

Clastic sedimentary rocks of Quantou Formation, Cretaceous in Qing-an area, Songliao basin are mainly composed of sandstone, mudstone and siltstone. The petrological-chemical analysis of clastic sedimentary rocks from Quantou Formation, Cretaceous indicates that their lithology mainly consists of arkose, shale and minor rock debris sandstone and greywacke by chemical classification of bulk elements. REE distribution pattern displays the apparent enrichment of LREE and negative anomaly of Eu and is similar to that of NASC and PAAS. The ratio of trace-element in sedimentary rocks to that of upper crust shows gentle character. All the above features indicate that these sedimentary rocks were slowly deposited under weakly active tectonic setting. They are sediments typical for passive continental margin and active continental margin. It is suggested that material source of clastic sediments of Quantou Formation, Cretaceous in Qing-an area, Songliao basin was originated from Hercynian granite of Zhangguangchai Mountain, and the granite was originated from upper crust.

Inhibition of leukocyte-type 12-lipoxygenase by guava tea leaves prevents development of atherosclerosis.

Science.gov (United States)

Takahashi, Yoshitaka; Otsuki, Akemi; Mori, Yoshiko; Kawakami, Yuki; Ito, Hideyuki

2015-11-01

Oxidation of low-density lipoprotein (LDL) is one of the crucial steps for atherosclerosis development, and an essential role of leukocyte-type 12-lipoxygenase expressed in macrophages in this process has been demonstrated. The biochemical mechanism of the oxidation of circulating LDL by leukocyte-type 12-lipoxygenase in macrophages has been proposed. The major ingredients in guava tea leaves which inhibited the catalytic activity of leukocyte-type 12-lipoxygenase were quercetin and ethyl gallate. Administration of extracts from guava tea leaves to apoE-deficient mice significantly attenuated atherogenic lesions in the aorta and aortic sinus. We recently showed that Qing Shan Lu Shui inhibited the catalytic activity of leukocyte-type 12-lipoxygenase. The major components inhibiting the enzyme contained in Qing Shan Lu Shui were identified to be novel monoterpene glycosides. The anti-atherogenic effect of the tea leaves might be attributed to the inhibition of leukocyte-type 12-lipoxygenase by these components. Copyright © 2015 Elsevier Ltd. All rights reserved.

Up-down quark mass difference effect in nuclear many-body systems

1995-01-01

A charge-symmetry-breaking nucleon-nucleon force due to the up-down quark mass difference is evaluated in the quark cluster model. It is applied to the shell-model calculation for the isovector mass shifts of isospin multiplets and the isospin-mixing matrix elements in 1s0d-shell nuclei. We find that the contribution of the quark mass difference effect is large and agrees with experiment. This contribution may explain the Okamoto-Nolen-Schiffer anomaly, alternatively to the meson-mixing contribution, which is recently predicted to be reduced by the large off-shell correction.

Shaping of the Yunnan-Burma Frontier by Secret Societies since the End of the 17th Century Comment les sociétés secrètes ont façonné la frontière birmano-yunnanaise

Directory of Open Access Journals (Sweden)

2012-10-01

Full Text Available After the 1680s, Big Vehicle Religion gradually developed on the Yunnan-Burma frontier. It was banned by the Qing government and became a sect of Chinese secret societies. The founders of this religion combined various Buddhist and Taoist elements together and claimed this to be the route to their salvation. They also trained many students to be monks. After the Sino-Burma wars these monks established a Five Buddha Districts system among the Lahu and some Wa villages in western Mekong River, until the system was destroyed by the Qing government in the 1880s. The monks became leaders of the Luohei/Lahu through millenarianism and many Han immigrants also became involved in the movements to become the Lahu or the Wa. The monks performed critical roles as social activists in Lahu cultural reconstruction. As a shaping power, their human agency was deeply integrated into secret societies and they formulated regional political centers as well as a network mechanism for the floating indigenous populations. Secret societies clearly shaped a historical framework for local politics and economic flux in the Yunnan-Burma frontier and became a cross-border mechanism for contemporary life after the border between Yunnan, Burma and Thailand was decided. However, it used to be a networking dynamic linked with silver and copper minefields, Sino-Burma wars, and anti-Qing millenarianism. Local people could also use this frontier space for their negotiations with different states before the coming of European colonialism.Après les années 1680, le bouddhisme du grand véhicule se développa sur la frontière birmano-yunnanaise. Le gouvernement des Qing l’interdit mais il devint une secte diffusée par des sociétés secrètes. Les fondateurs de cette religion combinèrent des éléments bouddhistes et taoïstes et prétendirent que c’était la voie du salut. Ils formèrent également des élèves pour en faire des moines.

Relationship between ancient bridges and population dynamics in the lower Yangtze River Basin, China.

It has been suggested that population growth dynamics may be revealed by the geographic distribution and the physical structure of ancient bridges. Yet, this relationship has not been empirically verified. In this study, we applied the archaeological records for ancient bridges to reveal the population growth dynamics in the lower Yangtze River Basin in late imperial China. We investigated 89 ancient bridges in Yixing that were built during the Ming and Qing dynasties (AD1368-1911). Global Position System information and structure (length, width, and span) of those bridges was measured during our field investigations. Their distribution density was calculated by ArcGIS. The historical socio-economic dynamics of Yixing was inferred from the distribution and structure of ancient bridges. Based on the above information, the population growth dynamics in Yixing was projected. Our results show that 77 bridges were built in Yixing during the Qing dynasty, which is 6.41 times more than the number built during the Ming dynasty. In the Ming dynasty, bridges were built on pivotal routes; in the Qing dynasty, bridges were scattered across various places. Over the period, the density distribution of bridges shifted northwestward, while the average length and width of bridges decreased. The increasing number of bridges corresponded to population growth, largely attributable to massive clan migration from northern China during the Little Ice Age. The shift in the density distribution of bridges corresponded to the formation of settlements of large clans and the blossoming of Yixing Teapot handicrafts. The scattering and the reduction in average length and width of bridges was due to the dispersal of population and the associated formation of small settlements in the latter period. Our approach is innovative and robust, and could be employed to recover long-term historical population growth dynamics in other parts of China.

Full Text Available Vagabonds, swindlers, bandits, and rebels. These figures may lie in quiet corners of Qing archives, but under the pen of historian Jodi Weinstein, they not only come alive, but ring out their voices, enmeshed with regional history and state formation. Focusing on the Zhongjia, who are believed to be the forbears of the current day Buyi (Bouyei minzu – one of China's fifty-six state-designated nationalities – Weinstein is interested in how members of such a lesser-known ethnic group in late imperial China's southwestern frontier responded to state centralization with ingenuity. Giving equivalent attention to both imperial and indigenous perspectives, Weinstein carries out a careful, honest examination of historical narratives and livelihood strategies from below. Empire and Identity in Guizhou: Local Resistance to Qing Expansion is thus a timely and refined contribution to the recent waves of scholarship engaged in reappraising agency and livelihoods in the Sino-Southeast Asian borderlands, also known as 'Zomia' in Scott's 2009 influential monograph The Art of Not Being Governed: An Anarchist History of Upland Southeast Asia. ...

[The textual research on the evolution of the toothbrush shape in ancient China].

Science.gov (United States)

Wu, Qiu-Peng

2012-05-01

Archaeological discovery demonstrates that the ancient plant hair brush first appeared in the Tang dynasty. According to the evolution of the shape of the head and handle of the toothbrush in ancient times, we can divide the evolution of the shapes into three major stages of development: (1) the Tang and the Five dynasties; (2) the Liao, Song, Jin, Yuan dynasties; (3) Ming, Qing and the Republic periods. The toothbrush heads and handles had no significant differences during the Tang and the Five dynasties. However, the shapes of them in the Liao, Song, Jin, Yuan dynasties are somewhat different. In the Ming and Qing and the republic of China periods, the shape of toothbrush head and handle had further refinement. Recently, some scholars raised doubts about the "plant hair toothbrush doctrine". They believe that the archaeological bone graft handle brush was used to wipe hair oil or clean water when washing and dressing. However, according to shape and function and ancient literature records, the archaeological bone graft handle brush should be a plant hair toothbrush used to clean and protect teeth.

Satire, as a mode, is not frequently employed in Chinese narratives. "Cat Country," or "Mao Cheng Ji," written by Lao She (pen name of Shu Qing Chun, 1898--1966) has come under much attack of its literary values. Whereas most critics have no doubt that this work sets out to satirize China through the portrayal of a society of…

Land contracts are important histor-ical records showing the changes in landowner rights, and reflect the social, economic, political and cultural development of a specific historical period. Dongba script land contracts are one of the significant categories of the practical texts of the Naxi that are written in Dongba pictographs, and as such are valuable to researchers. Li Xi’s article, Lijiang Baoshan Naxi xiangxing wenzi kao ( An Ex-ploration on the Bricks Inscribed with Naxi Picto-graphs in Baoshan of Lijiang) , is the earliest pub-lication related to land contracts written in Dongba pictographs. As a member of the team that com-piled Zhongguo shaoshu minzu guji zongmu tiyao · Naxi juan ( Ancient Manuscripts Contents of China’s Ethnic Minorities · Naxi Volume ) , I in-cluded seven Dongba script land contracts in the book, and provided a translation of the content of the contracts. Yu Suisheng has done a detailed re-search on several Dongba land contracts. In his Naxi dongba diqi yanjiu shuyao ( A Review of Naxi Dongba Land Contracts) , a comprehensive discus-sion on the collection, publication and research of the land titles is provided. Except from this, there has been little research on Dongba land contracts in the academic circle. Bowan village belongs to Sanba township, Shangri-la county, Yunnan province; it is a vil-lage in Baidi, the sacred place of the Naxi Dongba religion;and the Dongba culture flourished in this area throughout history. Until the 1950s, in addi-tion to being used for writing religious manuscripts, Dongba pictographs were also used to write con-tracts, record accounts or write letters. In our fieldwork, we found that Bowan village is one of the villages where Dongba literature has been well preserved in modern-day Naxi areas. This article mainly focuses on a discussion of ten Dongba script land contracts from the late Qing and Republican periods at Bowan village, and makes a preliminary research on their form, content, date of

Relativistic deformed mean-field calculation of binding energy differences of mirror nuclei

International Nuclear Information System (INIS)

Koepf, W.; Barreiro, L.A.

1996-01-01

Binding energy differences of mirror nuclei for A=15, 17, 27, 29, 31, 33, 39 and 41 are calculated in the framework of relativistic deformed mean-field theory. The spatial components of the vector meson fields and the photon are fully taken into account in a self-consistent manner. The calculated binding energy differences are systematically smaller than the experimental values and lend support to the existence of the Okamoto-Nolen-Schiffer anomaly found decades ago in nonrelativistic calculations. For the majority of the nuclei studied, however, the results are such that the anomaly is significantly smaller than the one obtained within state-of-the-art nonrelativistic calculations.

Understanding the “New Confucianism”: Reinventing Confucianism and the Future of China

Directory of Open Access Journals (Sweden)

André Bueno

2016-05-01

Full Text Available This article focuses on an important change in Chinese thinking of the 20th century: the rebirth of Confucianism as the intellectual movement called “New Confucianism” which is considered in the China of today to be a possible substitute for Marxist ideology. But what exactly is the “New Confucianism”? The author first attempts to highlight the definition of Confucianism from the Western perspective and the problems that arise in that process. The study is based primarily on the work of Jiang Qing 蒋庆, one of the principal thinkers of this movement of ideas, and on the analysis of the main western interpreter of Qing, researcher Daniel Bell. Further along, the paper discusses some of the most common tags of this movement: New Confucianism as a religion, as a social doctrine, and as a new political option for the future. Notwithstanding the elusiveness of the concept it appears to be the case that this movement is developing spontaneously in modern Chinese society and is gaining more and more followers, even via a lighter literary genre through which modified Confucian thoughts and tips for coping with everyday life can approach a wider crowd.

This paper, obtaining 39scenesof images of the Sentinel-1 A/B, monitored the Cangzhou area subsidence from Mar. 2015 to Dec. 2016 basing on using PS-InSAR technique. The annual average subsidence rate and accumulative subsidence were obtained. The results showed that the ground surface of Xian County,Cang County, Cangzhou urban area had a rebound trend; Qing County, the east of Cang County ,the west of Nanpi County and Dongguang County appeared obvious subsidence, and the accumulated subsidence in Hezhuang village of Dongguang County reached 47 mm. And from that the main reason leading to these obvious subsidence was over-exploitation of ground-water. At last, it analyzed the settlement of the High-Speed Railway (HR) which was north from the Machang town of QingCounty and south to the Lian town of Dongguang County in Cangzhou.The relative deformation of the HR between the two sections which was Lierzhuang village of Cang County and Chenxin village of Nanpi County arrived at 30 mm. Moreover, this paper discussed the application of Sentinel-1 A/B SAR images in monitoring urban land subsidence and the results provided important basic data for the relevant departments.

Full Text Available This article extends cartography into ethnographic and representational practices for territorial inclusion (Hostetler 2005 and nation building (Krishna 1994. Outer Mongolia, a vassal state of the Qing Empire until 1911, produced ethnographic paintings intended as new cartographic visuals around the time of its independence. Mongolia’s last ruler, the Bogd Khan (1870–1924 commissioned the artist Balduugin Sharav to produce a large painting of the Mongol countryside titled Daily Events, a work that constitutes an unusual cartographic “picture-map” (Paul Harvey 1980 intended for a special public display. The work (now known as One Day in Mongolia depicts the Mongolian people as a distinct ethnic group in quotidian scenes of Central Mongolian (Khalkha nomadic life. This article demonstrates how the covert connections between the scenes together construct a Buddhist didactic narrative of the Wheel of Life, and argues that this picture-map was the result of the Tibetan-born ruler’s anxieties over ethnic identity, national unity, and the survival of his people, who strove for independence from the Qing, as well as their safe positioning vis-à-vis new political neighbors.

A new method for compensation of the effect of charging transformer's leakage inductance on PFN voltage regulation in Klystron pulse modulators

Energy Technology Data Exchange (ETDEWEB)

Patel, Akhil, E-mail: akhilpatel@rrcat.gov.in; Kale, Umesh; Shrivastava, Purushottam

The Line type modulators have been widely used to generate high voltage rectangular pulses to power the klystron for high power RF generation. In Line type modulator, the Pulse Forming Network (PFN) which is a cascade combination of lumped capacitors and inductors is used to store the electrical energy. The charged PFN is then discharged into a klystron by firing a high voltage Thyratron switch. This discharge generates a high voltage rectangular pulse across the klystron electrodes. The amplitude and phase of Klystron's RF output is governed by the high voltage pulse amplitude. The undesired RF amplitude and phase stability issues arises at the klystron's output due to inter-pulse and during the pulse amplitude variations. To reduce inter-pulse voltage variations, the PFN is required to be charged at the same voltage after every discharge cycle. At present, the combination of widely used resonant charging and deQing method is used to regulate the pulse to pulse PFN voltage variations but the charging transformer's leakage inductance puts an upper bound on the regulation achievable by this method. Here we have developed few insights of the deQing process and devised a new compensation method to compensate this undesired effect of charging transformer's leakage inductance on the pulse to pulse PFN voltage stability. This compensation is accomplished by the controlled partial discharging of the split PFN capacitor using a low voltage MOSFET switch. Theoretically, very high values of pulse to pulse voltage stability may be achieved using this method. This method may be used in deQing based existing modulators or in new modulators, to increase the pulse to pulse voltage stability, without having a very tight bound on charging transformer's leakage inductance. Given a stable charging power supply, this method may be used to further enhance the inter-pulse voltage stability of modulators which employ the direct charging, after replacing the

Full Text Available Northeast China as a Contact Zone in Polish and Serbian Travelogues, 1900-1939 Historically, Northeast China (Manchuria was a border zone between China and nomadic peoples, as well as between Russian and Qing empires since the 17th century. In the second half of the 19th century and in the first half of the 20th century, a number of factors (penetration by foreign powers, collapse of the Qing Empire, revolution in Russia, Japanese expansion and demographic changes transformed this area into “a contact zone” in the sense given by Mary Louise Pratt. The main focus of the article is the way in which this contact zone was described by Polish and Serbian travellers. Their can provide a special outlook, because Poland and Serbia did not participate extensively in the colonial penetration into China, however, Serbs and Poles travelled there, often representing Russian institutions. Therefore they were observing China as agents of imperial force, but they did not identify themselves fully with it. Our analysis of the image of Northeast China as a contact zone will be divided into three broad sections: 1 political and military expansion, 2 economic and demographic relations, 3 transcultural phenomena of everyday life.   Chiny Północno-Wschodnie jako strefa kontaktu w polskich i serbskich relacjach podróżniczych w latach 1900-1939 Północno-wschodnie Chiny (Mandżuria są historyczną granicą między Chinami a ludami wędrownymi, od siedemnastego wieku również między Rosją a imperium dynastii Qing.

Traditional Chinese medicine (TCM) has long been used for patients with psoriasis. This study aimed to investigate TCM usage in patients with psoriasis. We analyzed a cohort of one million individuals representing the 23 million enrollees randomly selected from the National Health Insurance Research Database in Taiwan. We identified 28,510 patients newly diagnosed with psoriasis between 2000 and 2010. Among them, 20,084 (70.4%) patients were TCM users. Patients who were female, younger, white-collar workers and lived in urbanized area tended to be TCM users. The median interval between the initial diagnosis of psoriasis to the first TCM consultation was 12 months. More than half (N = 11,609; 57.8%) of the TCM users received only Chinese herbal medicine. Win-qing-yin and Bai-xian-pi were the most commonly prescribed Chinese herbal formula and single herb, respectively. The core prescription pattern comprised Mu-dan-pi, Wen-qing-yin, Zi-cao, Bai-xian-pi, and Di-fu-zi. Patients preferred TCM than Western medicine consultations when they had metabolic syndrome, hepatitis, rheumatoid arthritis, alopecia areata, Crohn's disease, cancer, depression, fatty liver, chronic airway obstruction, sleep disorder, and allergic rhinitis. In conclusion, TCM use is popular among patients with psoriasis in Taiwan. Future clinical trials to investigate its efficacy are warranted. PMID:27822287

Victorianizing Guangxu: Arresting Flows, Minting Coins, and Exerting Authority in Early Twentieth-Century Kham

Directory of Open Access Journals (Sweden)

Scott Relyea

2016-06-01

Full Text Available In the late Qing and early Republican eras, eastern Tibet (Kham was a borderland on the cusp of political and economic change. Straddling Sichuan Province and central Tibet, it was coveted by both Chengdu and Lhasa. Informed by an absolutist conception of territorial sovereignty, Sichuan officials sought to exert exclusive authority in Kham by severing its inhabitants from regional and local influence. The resulting efforts to arrest the flow of rupees from British India and the flow of cultural identity entwined with Buddhism from Lhasa were grounded in two misperceptions: that Khampa opposition to Chinese rule was external, fostered solely by local monasteries as conduits of Lhasa’s spiritual authority, and that Sichuan could arrest such influence, the absence of which would legitimize both exclusive authority in Kham and regional assertions of sovereignty. The intersection of these misperceptions with the significance of Buddhism in Khampa identity determined the success of Sichuan’s policies and the focus of this article, the minting and circulation of the first and only Qing coin emblazoned with an image of the emperor. It was a flawed axiom of state and nation builders throughout the world that severing local cultural or spiritual influence was possible—or even necessary—to effect a borderland’s incorporation.

Today, patients' families in the West are regaining the access to hospitals that they lost when hospitals emerged as the primary site for medical treatment, research and training at the beginning of the twentieth century. In China, however, families were never excluded from American mission-run hospitals, in fact, they were indispensable. Families were in the waiting rooms, consulting rooms,wards and operating theatres. They provided more than reassurance and comfort: they fed and nursed their sick relatives, acted as advocates and middlemen and may even have lowered the incidence of cross-infection, the scourge of the contemporary hospital in the West.

Channel Evolution Following Avulsion: an Example from the Yellow River Delta

Science.gov (United States)

Zheng, S.

2017-12-01

Long-term field observation of morphological adjustments of rivers following avulsions is lacked when studying the evolution of avulsive channel on deltas. Avulsion at the Yellow River Delta (YRD) is frequent with average lifespan of channels of only about a decade. The Qing-shui-gou channel, the recent lobe on the YRD, provides a rare opportunity for investigating channel evolution following artificial avulsion. The reasons for its longer lifespan also needs investigation of the channel evolution. In this study, we comprehensively analyzed the geomorphic adjustment of the channel based on filed survey data during 1976-2014. The evolution of the channel was impacted by anthropogenic activities, including artificial avulsion at the downstream channel reaches in 1996, alteration of runoff and sediment load through Water and Sediment Regulation Scheme (WSRS), construction of levees and dikes. Analysis on channel geometry showed that avulsions in 1976 and in 1996 both caused short-term (1 2 years) erosion at the upstream channel reaches. Following the avulsion in 1976, massive aggradation occurred at the channel reaches at the downstream of the avulsion point. A single-thread channel gradually formed, widened and enlarged as channel bed under-cut on the deposition material. As delta extended seaward and the longitudinal slope decreased with time, aggradation occurred and an alluvial ridge formed. The ratio of lateral slope to the longitudinal slope (i.e. gradient advantage) and the relative super-elevation of the channel were calculated to estimate the possibility of avulsion at the channel in the late 1990. Results showed that the slope ratio was greater than 20 locally and super-elevation near its critical value for avulsion. The fact, that natural avulsion did not occurred despite of high values of gradient advantage and super elevation, may indicate that they are not sufficient conditions for avulsion at highly human-controlled rivers, where channel boundaries are

Victorian naturalists in China: science and informal empire.

Science.gov (United States)

Fan, Fa-ti

2003-03-01

This paper discusses the research of British naturalists in China during the period between the Opium War and the collapse of the Qing dynasty (1839-1911). China was defeated in the Opium War and forced to open treaty ports for trade with the Westerners. The foreign powers, particularly Britain, imposed upon the Qing government treaties, concession leases, favourable trade conditions, legal privileges and so on to reduce its political autonomy. In the shadow of the informal empire, not only did the British have more freedom to travel in China, first at the treaty ports and later in the interior, but they successively established diplomatic , commercial and missionary institutions in dozens of Chinese cities. The most important of them - the British Consular Service, the Chinese Maritime Customs and the Protestant missionary organizations - provided the talent and infrastructure for natural historical research and became networks for scientific information. The research into China's natural history epitomized the characteristics of British research on China in general: it engaged in collecting and circulating an ever-increasing amount of information and aimed at producing 'factual' and 'useful' knowledge about China. The paper modified current literature on scientific imperialism, which has dealt primarily with the colonial context, by examining the role of nineteenth-century British imperial science in the context of informal empire.

The median interval between the initial diagnosis of psoriasis to the first TCM consultation was 12 months. More than half (N=11,609; 57.8% of the TCM users received only Chinese herbal medicine. Win-qing-yin and Bai-xian-pi were the most commonly prescribed Chinese herbal formula and single herb, respectively. The core prescription pattern comprised Mu-dan-pi, Wen-qing-yin, Zi-cao, Bai-xian-pi, and Di-fu-zi. Patients preferred TCM than Western medicine consultations when they had metabolic syndrome, hepatitis, rheumatoid arthritis, alopecia areata, Crohn’s disease, cancer, depression, fatty liver, chronic airway obstruction, sleep disorder, and allergic rhinitis. In conclusion, TCM use is popular among patients with psoriasis in Taiwan. Future clinical trials to investigate its efficacy are warranted.

Presentation of Austrians recommended dispersion model for tunnel portals

Energy Technology Data Exchange (ETDEWEB)

Oettl, D.; Sturm, P.; Almbauer, R. [Inst. for Internal Combustion Engines and Thermodynamics, Graz Univ. of Technology (Austria)

2004-07-01

Street tunnels in cities are often suggested as solution to avoid daily congestions but also to prevent residential areas from high noise and air pollution emissions. In case of longitudinal ventilated tunnels high pollution levels may occur in the vicinity of the portals. The dispersion of pollutants from tunnel portals is considered to differ significantly from those of other sources, such as line or point sources. To the best of the authors knowledge, there exist currently two distinct dispersion models, which are especially designed to treat dispersion from tunnel portals. Okamoto et al proposed a diagnostic wind field model, where the dispersion is modelled using a Taylor-Galerkin-Forester filter method. Oettl et al. developed a Lagrangian-type model (GRAL TM 3.5=Graz Lagrangian model Tunnel Module version 3.5), which is briefly described in the next section. (orig.)

A preliminary study of international migration of the Chinese people.

Science.gov (United States)

Zhu, G

1994-01-01

International Chinese migration has spanned five periods: 1) an initial period of random and short-term migration dating back to the Qing and Han dynasties; 2) a spontaneous period since the Sui and Tang dynasties along trade routes; 3) a transition period during the Ming dynasty and the early Qing dynasty with war, poverty, and population growth as push factors; 4) peak migration during the Opium War period due to economic depression, population pressure, and the "coolie" trade; and 5) continuous development between the 1920s and 1949. Migration tended to occur between Guangdong and Fujian provinces and other southeast Asian countries. Four factors were identified as necessary for international migration to occur: the origin of migration, the destination factor, the middle link factor, and the immigrant characteristics. The origins of early Chinese migration appeared in a country of political corruption, population pressure, a backward economy, and social chaos. The pull factors at destination end were demand for labor. The middle link was the short distance between Guangdong and Fujian provinces and southeast Asian countries and longstanding nongovernmental exchanges. Other links were the similarity of climate, similar racial features, cultural lifestyle similarities, and convenient transportation. The people in these two provinces had a history of migration and a personality suitable for the spirit of adventure. Peak migration occurred during the late Qing dynasty and during the continuous development period. Between 1840 and 1911 there were about 10 million Chinese immigrants and during 1911 and 1949 there were about 6 million. In general, over 20 million immigrated prior to 1949, of which about 50% migrated during the peak period, 33% during the continuous period, and 20% before 1840. This amounted to about 33% of European migration and two times African migration. 60% were from Guangdong, and 30% were from Fujian province, of whom most were from counties

We present a homogenized surface air temperature (SAT) time series at 2 m height for the city of Qingdao in China from 1899 to 2014. This series is derived from three data sources: newly digitized and homogenized observations of the German National Meteorological Service from 1899 to 1913, homogenized observation data of the China Meteorological Administration (CMA) from 1961 to 2014 and a gridded dataset of Willmott and Matsuura (2012) in Delaware to fill the gap from 1914 to 1960. Based on this new series, long-term trends are described. The SAT in Qingdao has a significant warming trend of 0.11 ± 0.03 °C decade-1 during 1899-2014. The coldest period occurred during 1909-1918 and the warmest period occurred during 1999-2008. For the seasonal mean SAT, the most significant warming can be found in spring, followed by winter. The homogenized time series of Qingdao is provided and archived by the Deutscher Wetterdienst (DWD) web page under overseas stations of the Deutsche Seewarte (http://www.dwd.de/EN/ourservices/overseas_stations/ueberseedoku/doi_qingdao.html) in ASCII format.

Simple ortho- and para-hydroquinones as compounds neuroprotective against oxidative stress in a manner associated with specific transcriptional activation

Electrophilic compounds protect neurons through the activation of the Keap1/Nrf2 pathway and the induction of phase-2 enzymes [T. Satoh, S.A. Lipton, Redox regulation of neuronal survival by electrophilic compounds, Trends Neurosci. 30 (2007) 38-45; T. Satoh, S. Okamoto, J. Cui, Y. Watanabe, K. Furuta, M. Suzuki, K. Tohyama, S.A. Lipton, Activation of the Keap1/Nrf2 pathway for neuroprotection by electrophilic phase II inducers. Proc. Natl. Acad. Sci. USA 103 (2006) 768-773]. Hydroquinone-type electrophilic compounds such as tert-butyl hydroquinone (TBHQ) and carnosic acid (CA) have attracted special attention, because the oxidative conversion of 'hydroquinone' to 'quinone' is essential for the transcriptional activation of the above-mentioned enzymes [T. Satoh, K. Kosaka, K. Itoh, A. Kobayashi, M. Yamamoto, Y. Shimojo, C. Kitajima, J. Cui, J. Kamins, S. Okamoto, T. Shirasawa, S.A. Lipton, Carnosic acid, a catechol-type electrophilic compound, protect neurons both in vitro and in vivo through activation of the Keap1/Nrf2 pathway via S-alkylation of specific cysteine, J. Neurochem. 104 (2008) 1161-1131; A.D. Kraft, D.A. Johnson, J.A. Johnson, Nuclear factor E2-related factor 2-dependent antioxidant response element activation by tert-butylhydroquinone and sulforaphane occurring preferentially in astrocytes conditions neurons against oxidative insult, J. Neurosci. 24 (2004) 1101-1112]. In the present study, we examined the relationship between electrophilicity and the protective effects afforded by electrophilic compounds. Electrophilicity was assessed in terms of the ability of a compound to bind to a cysteine on bovine serum albumin, by which we found that neuroprotective hydroquinones [TBHQ (para-) and CA (ortho-)] had distinctive patterns of cysteine binding compared with other electrophilic compounds. Further, we found that isomers of simple ortho- and para-hydroquinones such as 2-methylhydroquinone (para-) and 4-methyl-catechol (ortho-) [not in abstract] had

We propose...... a general construction showing that any cryptographic primitive where the secret key can be chosen as a uniformly random string can be made s ecure against bounded tampering and leakage. This holds in a restricted model where the ta mpering functions must be chosen from a set of bounded size after...... arbitrarily tamper with the prover’s state a bounded number of times and/or obtain some bounded amount of leakage. Interestingly, for the Okamoto scheme we can allow also independent tampering with the public parameters. 3. We show a bounded tamper and leakage resilient CCA secure public key cryptosystem...

Hydraulic Theory and Hydraulic Engineering Projects of the Wusong River (吳淞江 Basin Between the Sixteenth and Nineteenth Centuries

Directory of Open Access Journals (Sweden)

Chulwoong Chung

2015-02-01

Full Text Available This paper attempts to explore the significance of the overall water control system and numerous water control projects in the Jiangnan region. Through a series of large-scale dredging projects, the Ming and Qing Dynasties attempted to achieve the goals of securing national tax revenue and guaranteeing the production activity for the farmers. However, due to the weakened hydraulic system, excessive expenses, and interests on various levels, large-scale hydraulic engineering projects were unable to achieve their original goals. Starting in the sixteenth century already, interests about practical one-time hydraulic engineering projects on a small scale began to surface. Meanwhile, in the Qing Dynasty, when the socio-economic transformation developed more, a new awareness of hydraulics surfaced due to the expansion of commercial cultivation over a large amount of land in the Jiangnan region. This was the result of an attempt to break away from the heavy dependence on water control facilities that had little room for improvement by growing a variety of plants and crops instead of focusing solely on simple grain production. Therefore the cultivation of a variety of commercial crops and plants and the development of the handicraft industry in the Jiangnan region since the sixteenth century are two aspects of Chinese society that resulted from ineffective water control facilities. However, despite these limitations and failures, large-scale hydraulic engineering projects were carried out repeatedly due to the economic importance of the Jiangnan region and to the efforts to achieve the ideals of flood control.

Coulomb displacement energies and neutron density distributions

International Nuclear Information System (INIS)

Shlomo, S.

1979-01-01

We present a short review of the present status of the theory of Coulomb displacement energies, ΔEsub(c), discussing the Okamoto-Nolem-Schiffer anomaly and its solution. We emphasize, in particular, that contrary to previous hopes, ΔEsub(c) does not determine rsub(ex), the root-mean square (rms) radius of the excess (valence) neutron density distribution. Instead, ΔEsub(c) is very sensitive to the value of Δr = rsub(n) - rsub(p), the difference between the rms radii of the density distributions of all neutrons and all protons. For neutron rich nuclei, such as 48 Ca and 208 Pb, a value of Δr = 0.1 fm is found to be consistent with ΔEsub(c). This value of Δr, which is considerably smaller than that (of 0.2 - 0.3 fm) predicted by some common Hartree-Fock calculations, seems to be confirmed by very recent experimental results. (orig.)

δ meson effects in the Nolen-Schiffer anomaly

International Nuclear Information System (INIS)

Menezes, D.P.; Avancini, S.S.; Vasconcellos, C.Z.; Razeira, M.

2009-01-01

In this work we revisit the Okamoto-Nolen-Schiffer (ONS) anomaly in the context of four parametrizations of effective hadronic models, two of them with constant couplings between the nucleons and the mesons and two with density-dependent couplings. A Thomas-Fermi approximation is performed and the effects of the isovector-scalar virtual δ (a 0 (980)) mesons are investigated since they influence directly the proton and neutron effective masses in opposite ways. The ρ-ω mixing term is claimed to be important in the explanation of the ONS anomaly and is added in our calculations. We have concluded that as far as the ρ-ω mixing term is included, Δ M(Z, N) is clearly larger in models with δ than in models where this meson is not considered, which is not always the case if the coupling is discarded. None of the models is good enough to describe all experimental data, but the models that better describe the experimental values include the δ mesons. (orig.)

Gravitational lensing of the CMB: A Feynman diagram approach

Directory of Open Access Journals (Sweden)

Elizabeth E. Jenkins

2014-09-01

Full Text Available We develop a Feynman diagram approach to calculating correlations of the Cosmic Microwave Background (CMB in the presence of distortions. As one application, we focus on CMB distortions due to gravitational lensing by Large Scale Structure (LSS. We study the Hu–Okamoto quadratic estimator for extracting lensing from the CMB and derive the noise of the estimator up to O(ϕ4 in the lensing potential ϕ. By identifying the diagrams responsible for the previously noted large O(ϕ4 term, we conclude that the lensing expansion does not break down. The convergence can be significantly improved by a reorganization of the ϕ expansion. Our approach makes it simple to obtain expressions for quadratic estimators based on any CMB channel, including many previously unexplored cases. We briefly discuss other applications to cosmology of this diagrammatic approach, such as distortions of the CMB due to patchy reionization, or due to Faraday rotation from primordial axion fields.

Phase identification based on nondestructive analytical techniques using portable equipment is ideal for the analysis of art and archaeological objects. Portable(p)-XRF and p-Raman are very widely used for this purpose, yet p-XRD is relatively rare despite its importance for the analysis of crystalline materials. This paper overviews 6 types of p-XRD systems developed for analysis of art and archaeological materials. The characteristics of each system are compared. One of the p-XRD systems developed by the authors was brought to many museums as well as many archeological sites in Egypt and Syria to characterize the cultural heritage artifacts, e.g., amulet made of Egyptian blue, blue painted pottery, and Islamic pottery from Egypt, jade from China, variscite from Syria, a Japanese classic painting drawn by Korin Ogata, and oil paintings drawn by Taro Okamoto. Practical application data are shown to demonstrate the potential ability of the method for analysis of various art and archaeological materials. (orig.)

Phase identification based on nondestructive analytical techniques using portable equipment is ideal for the analysis of art and archaeological objects. Portable(p)-XRF and p-Raman are very widely used for this purpose, yet p-XRD is relatively rare despite its importance for the analysis of crystalline materials. This paper overviews 6 types of p-XRD systems developed for analysis of art and archaeological materials. The characteristics of each system are compared. One of the p-XRD systems developed by the authors was brought to many museums as well as many archeological sites in Egypt and Syria to characterize the cultural heritage artifacts, e.g., amulet made of Egyptian blue, blue painted pottery, and Islamic pottery from Egypt, jade from China, variscite from Syria, a Japanese classic painting drawn by Korin Ogata, and oil paintings drawn by Taro Okamoto. Practical application data are shown to demonstrate the potential ability of the method for analysis of various art and archaeological materials. (orig.)

It has been recognised that high haemoglobin oxygen capacity is essential for the development of high blood pressure in spontaneously hypertensive rats. In the present study we have found increased concentration of 2,3 diphosphoglycerate (2,3-DPG) in red blood cells of spontaneously hypertensive rats (SHR) of Okamoto-Aoki strain. As 2,3-DPG is the major factor decreasing haemoglobin affinity to oxygen, our finding suggests that at given value of pO2 oxygen delivery to the tissue of SHR would be increased. Therefore increased concentration of 2,3-DPG in red blood cells of SHR would be of the pathophysiological meaning by promoting autoregulatory increase in total vascular resistance in this strain of rats. The mechanism responsible for enhanced synthesis of 2,3-DPG in SHR remains unclear. Intracellular alkalosis due to either hypocapnia and/or an enhanced activity of Na+/H+ antiporter occurring in SHR are the most plausible explanations for the above finding.

The purpose of this communication is to point out the connection between a 1D quantum Hamiltonian involving the fourth Painlevé transcendent P{sub IV}, obtained in the context of second-order supersymmetric quantum mechanics and third-order ladder operators, with a hierarchy of families of quantum systems called k-step rational extensions of the harmonic oscillator and related with multi-indexed X{sub m{sub 1,m{sub 2,…,m{sub k}}}} Hermite exceptional orthogonal polynomials of type III. The connection between these exactly solvable models is established at the level of the equivalence of the Hamiltonians using rational solutions of the fourth Painlevé equation in terms of generalized Hermite and Okamoto polynomials. We also relate the different ladder operators obtained by various combinations of supersymmetric constructions involving Darboux-Crum and Krein-Adler supercharges, their zero modes and the corresponding energies. These results will demonstrate and clarify the relation observed for a particular case in previous papers.

Hyperfine structures of ICl in its vibronic ground state due to the nuclear spin and electric quadruple interactions are determined by diagonalizing the effective Hamiltonian matrix. Furthermore, the Stark sub-levels are precisely determined as well. The results are helpful for electro-static manipulation (trapping or further cooling) of cold ICl molecules. For example, an electric field of 1000 V/cm can trap ICl molecules less than 637 μK in the lowest hyperfine level.

With the pace of the invasion of western powers,Christianity has been widely spread in China since the late Qing dynasty.As a kind of alien culture,Christianity and traditional Chinese culture frictioned inceasingly in the collision with each other, as a result of which,the collision between religion and Chinese people was one of important performance.In Shanxi,an inland province, the collision was abnormally fierce and characteristical, which was based on the unique local traditional social environment. The collision there was often caused by a traditional parade, where people raised the statue of god. Collision caused by the parade,in my opinion,is due to the violations and coflicts between the non-religious civilians and the officials in the aspects of cultural custom,economic interests, social organization and management.However,the official judgment,which was decided under the pressure of the central and foreign powers to avoid disaster,was usually on the side of the religious people.%晚清以来，伴随着西方列强入侵的步伐，基督教也在中国广泛传播起来。西方异质文化基督教在与传统中国文化和社会的碰撞中摩擦不断，民教冲突是其中一个重要表现。内陆省份山西基于其特有的传统地方社会环境，民教冲突异常激烈并且特点显著，由迎神赛会所引起的民教争端频繁发生。围绕迎神赛会产生的众多激烈的民教冲突，归根到底是由于非信教平民乃至官绅阶层与教民在文化习俗、经济利益、地方社会组织管理等各方面权益的相侵和冲突。官府对民教争讼的判决结果通常利于教民，这是处于中央和外国势力压力下的官员妥协自保的结果。

This study provides an improved method to root-cause analysis tool for practitioners, integrating mixed method research with problems identification technique. It also discovers the primary causes to  unfavorable performance for heritage boutique hoteliers. 1881 Chong Tian Cultural Hotel, one of the 18 heritage boutique hotels in Penang, reported a 23% financial loss in 2010, recovered in 2011, yield some profits in 2012 and 2013. However, growth in boutique hotel industry has been a challenge over the years. The sequential approach methodology, begins with sem-structured interviews, quantitative surveys on 100 general public and 56 hotel guests,  and analysis on unpublished company data, were summarized using a root-cause analysis tool called the Symptoms Versus Problems (SVP Framework that questioned on the occurance of the symptoms for the first three Tiers of the framework. The remaining symptoms and core problems are identified based on findings from all the three methods above plus field observations, concurrently. Two major symptoms are identified, specifically, unfavorable cultural service quality and ineffective marketing strategies. The unfavorable cultural service quality is due to ineffective cultural ambiance; unproductive display of heritage, cultural artifacts and infrastructure; as well as, unfavorable cultural related services. The ineffective marketing strategies are due to low technology adoption of websites and social media; and ineffective customer relationship management (CRM implementation. Thus, the recommended solutions bring to life the practices of Qing Dynasty cultural ambiance, ceremonies, historical shows and the royale reception. Information on artifacts and infrastructure is readily available. Website development and social media updates on latest Chong Tian Hotel activities are being developed.

Oasis evolution, one of the most obvious surface processes in arid regions, affects various aspects of the regional environment, such as hydrological processes, ecological conditions, and microclimates. In this paper, the historical spatio-temporal evolution of the cultivated oases in the Heihe River Basin, the second largest inland watershed in the northwest of China, was assessed using multidisciplinary methods and data from multiple sources, including historical literature, ancient sites, maps and remotely sensed images. The findings show that cultivated oases were first developed on a large scale during the Han Dynasty (121 BC-220) and then gradually decreased in extent from the Six Dynasties period (220-581) to the Sui-Tang period (581-907), reaching a minimum in the Song-Yuan period (960-1368). An abrupt revival occurred during the Ming Dynasty (1368-1644) and continued through the Qing Dynasty (1644-1911), and during the period of the Republic of China (1912-1949), oasis development reached its greatest peak of the entire historical period. The oasis areas during seven major historical periods, i.e., Han, Six Dynasties, Sui-Tang, Song-Yuan, Ming, Qing, and Republic of China, are estimated to have been 1703 km2, 1115 km2, 629 km2, 614 km2, 964 km2, 1205 km2, and 1917 km2, respectively. The spatial distribution generally exhibited a continuous sprawl process, with the center of the oases moving gradually from the downstream region to the middle and even upstream regions. The oases along the main river remained stable during most periods, whereas those close to the terminal reaches were subject to frequent variations and even abandonment. Socio-economic factors were the main forces driving the evolution of cultivated oases in the area; among them, political and societal stability, national defense, agricultural policy, population, and technological progress were the most important.

Stereodynamic tetrahydrobiisoindole “NU-BIPHEP(O”s: functionalization, rotational barriers and non-covalent interactions

Full Text Available Stereodynamic ligands offer intriguing possibilities in enantioselective catalysis. “NU-BIPHEPs” are a class of stereodynamic diphosphine ligands which are easily accessible via rhodium-catalyzed double [2 + 2 + 2] cycloadditions. This study explores the preparation of differently functionalized “NU-BIPHEP(O” compounds, the characterization of non-covalent adduct formation and the quantification of enantiomerization barriers. In order to explore the possibilities of functionalization, we studied modifications of the ligand backbone, e.g., with 3,5-dichlorobenzoyl chloride. Diastereomeric adducts with Okamoto-type cellulose derivatives and on-column deracemization were realized on the basis of non-covalent interactions. Enantioselective dynamic HPLC (DHPLC allowed for the determination of rotational barriers of ΔG‡298K = 92.2 ± 0.3 kJ mol−1 and 99.5 ± 0.1 kJ mol−1 underlining the stereodynamic properties of “NU-BIPHEPs” and “NU-BIPHEP(Os”, respectively. These results make the preparation of tailor-made functionalized stereodynamic ligands possible and give an outline for possible applications in enantioselective catalysis.

The Power of Interconnectivity: Tan Sitong's Invention of Historical Agency in Late Qing China

2015-02-01

Full Text Available To explore how Chinese Buddhists acted as trailblazers of Engaged Buddhism, I shall analyze a late nineteenth-century thinker, Tan Sitong 譚嗣同 (1865–1898. The focus of my analysis is his masterpiece, Renxue 仁學. From his position of Buddhist eclecticism, Tan discoursed at length on non-differentiation as the truth of the universe to reflect on the creative disposition of human agency. He described in Renxue how this disposition would contribute to the agendas defining Chinese modernity. In addition, discussing the meanings of non-differentiation, Tan also generalized about the nature of the human agency he attempted to advocate: while he perceived the human agency blessed with a non-differentiating mindset as an omnipotent history-making force, he also argued that it did not confer upon its owner the status of world savior. In fact, in his view, the efficacy of a non-differentiating mind was determined by the world it aimed to help. Tan's signature piece, I argue, provides a lens through which we can observe modern Chinese Buddhism's role as an important part of the global formation of Engaged Buddhism.

Political Reforms in a Global Context: Some Foreign Perspectives on Constitutional Thought in Late Imperial China

Full Text Available This paper presents some outside views on the emergence of Chinese constitutional thought. It shows that Chinese constitutionalism in the beginning of the 20th century did matter to the outside world and did attract a large interest on a global scale. Foreign views were quite diverse. While most observers welcomed the adoption of a constitution in principle, there were many words of caution that such a transition should not be rushed, notedly among diplomats and politicians. Foreign powers thus adopted a policy of not pressuring China to adopt a constitution. In particular, this paper redefines the role of the Japanese statesman Itô Hirobumi, who continually tried to give his advice to the Qing government up until his death in 1909.

Anti-opium-smoking had been the key policy of successive central and local governments from the late Qing Dynasty to the Republican Period. Since the establishment of the Nanjing Provisional Government in January 1912, the Anti-opium-smoking campaign had culminated across the country. Under the support of the government, the "National Anti-Opium Association of China" and "Association of Chinese People Rejecting Opium" were established which made an important contribution to China's anti-opium-smoking campaign.Yunnan, Shaanxi, Heilongjiang, Zhejiang, Shanghai and other local governments also combined with local specific circumstances to make anti-opium-smaking policy for punishing severely the opium cultivation, trade and opium smoking, thus, the overrun of opium began to be brought under an overall control.

Full Text Available Green lacewing Mallada boninensis is an important predator of various soft-bodied arthropods, including red spider mites in tea. Efforts were made to develop mass rearing technology for this predator in a cost effective manner. Three combinations of artificial diets (Protinex (AD1, egg yolk (AD2 and royal jelly (AD3 based were evaluated in comparison with standard diet (Protinex + Honey. All the tested diets influenced the egg-laying capacity of M. boninensis. The egg yolk-based diet resulted in more egg production than the other two diets. Survival of all life stages of M. boninensis was also observed on each diet and no significant difference was noticed. Results revealed that the egg yolk-based diet is the best of the three diet combinations tested in view of high fecundity and survival rate of M. boninensis.

Unveiling the curtain of superposition: Recent gedanken and laboratory experiments

What is the true meaning of quantum superposition? Can a particle genuinely reside in several places simultaneously? These questions lie at the heart of this paper which presents an updated survey of some important stages in the evolution of the three-boxes paradox, as well as novel conclusions drawn from it. We begin with the original thought experiment of Aharonov and Vaidman, and proceed to its non-counterfactual version. The latter was recently realized by Okamoto and Takeuchi using a quantum router. We then outline a dynamic version of this experiment, where a particle is shown to “disappear” and “re-appear” during the time evolution of the system. This surprising prediction based on self-cancellation of weak values is directly related to our notion of Quantum Oblivion. Finally, we present the non-counterfactual version of this disappearing-reappearing experiment. Within the near future, this last version of the experiment is likely to be realized in the lab, proving the existence of exotic hitherto unknown forms of superposition. With the aid of Bell’s theorem, we prove the inherent nonlocality and nontemporality underlying such pre- and post-selected systems, rendering anomalous weak values ontologically real.

Predicting Three-Dimensional Conformations of Peptides Constructed of Only Glycine, Alanine, Aspartic Acid, and Valine

2015-06-01

The GADV hypothesis is a form of the protein world hypothesis, which suggests that life originated from proteins (Lacey et al. 1999; Ikehara 2002; Andras 2006). In the GADV hypothesis, life is thought to have originated from primitive proteins constructed of only glycine, alanine, aspartic acid, and valine ([GADV]-proteins). In this study, the three-dimensional (3D) conformations of randomly generated short [GADV]-peptides were computationally investigated using replica-exchange molecular dynamics (REMD) simulations (Sugita and Okamoto 1999). Because the peptides used in this study consisted of only 20 residues each, they could not form certain 3D structures. However, the conformational tendencies of the peptides were elucidated by analyzing the conformational ensembles generated by REMD simulations. The results indicate that secondary structures can be formed in several randomly generated [GADV]-peptides. A long helical structure was found in one of the hydrophobic peptides, supporting the conjecture of the GADV hypothesis that many peptides aggregated to form peptide multimers with enzymatic activity in the primordial soup. In addition, these results indicate that REMD simulations can be used for the structural investigation of short peptides.

The relationship between brain CT findings and the total dose of antipsychotic drugs was examined in 47 cases with schizophrenia ranging from 20 to 42 years in age (31 males and 16 females). The methods of Gyldensted et al. and Okamoto et al. were modified for CT measurements. The total dose during the entire course was converted into the dose of chlorpromazine (CPZ) for each case. For comparisons with CT findings, the total dose was classified into three types each for both sexes: ''less than'' 100 g, ''less than'' 500 g and ''more than'' 500 g for the males and ''more than'' 500 g, ''less than'' 1,000 g and ''more than'' 1,000 g for the females. For similar comparisons, the same subjects were matched for the age and sex distinction, and were divided into the ''less than'' and ''more than'' groups for 500 g and 800 g, respectively. In both the matched and non-matched cases, each measurement value of the ventricular system on CT tended to be higher in the ''more than'' groups than in the ''less than'' groups. The relationship between CT findings and the total dose was nogligible. (Chiba, N.)

In our previous theoretical studies [Meng-Tao Sun, Yong-Qing Lee, and Feng-Cai Ma, Chem. Phys. Lett. 371 (2003) 342], we have reported the quantum interference on collision-induced rotational energy transfer on CO (A 1 Π, v = 3) with inert gases, which originates from the difference between the two Λ-related collision potential energy surfaces. The interference angle, which measures the degree of coherence, is presented in this paper. Based on the time-dependent first order Born approximation, taking into account the anisotropic Lennard-Jones interaction potentials, the relation of the interference angle with the factors, including experimental temperature, partner, and rotational quantum number, are obtained. The changing tendencies with them are discussed. This theoretical model is important to understanding and performing this kind of experiment.

Guangzhou’s Baozai Meal a Popular Fast Food

1995-01-01

IN Guangzhou, where restaurants are plentiful and food from many places is served, the baozai meal, a kind of traditional Chinese fast food, has retained its place in the hearts of Guangzhou’s caterers. The history of the baozai meal starts at least from the beginning of this century. By the end of the Qing Dynasty, Guangzhou was the largest trading port in south China with a developed, commodities-based economy. There were many dockworkers and porters living in the city at the time. They worked very hard and were often too busy to eat their meals at home. As a result, different kinds of meals were invented to meet their needs, such as the botou meal (bo is kind of earthen bowl), the dietou meal (die is small plate) and the baozai meal

The performance of the micro-X-ray fluorescence based on the slightly focusing polycapillary optics were investigated. While the chemical compositions of a piece of Pb-rich colored porcelain fired in Qing Dynasty were analyzed by micro-X-ray fluorescence. From the results, the processes of decorative technologies can be deduced as follows. A kind of pigments with high concentrations of Mn and Pb or with high concentrations of Fe and Pb was used to draw the profiles of designed paintings on the body of porcelain. Cu and its mixture with high concentration of Pb were filled in the desired positions. It is proved that polycapillary optics can play an important role in the analysis of the chemical characters and decorative technologies of pigments of colored porcelain. (authors)

Religion, State and Civil Religion： Assumption and Practice of Confucian Religion in the Course of Nation-state Construction CAN Chun-song Abstract： In late Qing Dynasty and the early years of the Republic of China, Kang You-wei made a proposal to set Confucian religion as state religion. After analyzing carefully Kang＇s related texts, however, it can be shown that Kang had unique understandings of ＂religion＂ and ＂state religion＂. Kang defined Confucianism as religion in the sense of cultivation, and emphasized that the function of Confucianism was moral education. Kang＇s understanding of ＂state religion＂ aims to conserve Chinese traditional cultures and customs, shape the identity of nation-state, and enhance the state＇s cohesion. In this sense, Kang＇s definition of ＂national religion＂ is similar to to Bellah＇s ＂civil religion＂.

While the basic physics of Microwave Assisted Magnetization Reversal (MAMR) phenomenon is well established both theoretically and experimentally, its application in a practical magnetic recording environment was so far studied primarily with the help of micromagnetic recording models. In this work, we instead attempt to use analytical formulation and simple numerical models to understand the main challenges as well as benefits that are associated with such a system. It appears that the main difference between the previously introduced theory [G. Bertotti et al., Phys. Rev. Lett. 86, 724 (2001); K. Rivkin et al., Appl. Phys. Lett. 92, 153104 (2008); S. Okamoto et al., J. Appl. Phys. 107, 123914 (2010).] and recording environment is that both the RF and DC magnetic fields are applied at a substantial angle to the anisotropy axis. While the associated symmetry breaking prevents one from describing the reversal process explicitly, it is possible to approximate the solutions well enough to satisfactorily match numerical models both in the case of wire and Spin Torque Oscillator generated RF fields. This approach allows for physical explanation of various effects associated with MAMR such as high gradient of writeable anisotropy and reduction of track width, and offers a clear guidance regarding future optimization of MAMR recording.

We have in the last two years, performed PRK operation on over 300 human myopic eyes using ArF excimer laser with a Summit 'Omnimed' machine. For the initial 53 myopic eyes we treated, results were very good for those with correction less than minus 6 diopters. However, as previously reported, we also witnessed some regression for those eyes exceeding correction of more than minus 6 diopters. To counter such ill results of PRK we devised and suggested many new procedures for PRK with very good results. One such invention is the 'Okamoto-type' cooling machine for the cornea which reduces and stabilizes cornea temperature at 0 degrees Celsius while simultaneously bathing the cornea with special cooling fluid. After the operation, EGF, fibronectin and hexapeptide were administered using eyedrops. Soft contact lenses were used to protect the cornea, improve delivery of medication to the operated area, prevent infection and inflammation and also promote uniform and faster ephiterium regrowth. We were able to document very good post-operative results using this method, thereby giving us strong assurance that we have reached a significant milestone in PRK operation. Our report today covers post operative results of the 52 eyes we operated on and tracked for more than one year.

Tracy and Widom have evaluated the cumulative distribution of the largest eigenvalue for the finite and scaled infinite Gaussian unitary ensemble (GUE) in terms of a Painleve IV and Painleve II transcendent respectively. We generalise these results to the evaluation of E N (λ;a) :(Π n l=1 χ (l) (-∞,λ) (λ - λ l ) a ), where χ (l) (-∞) = 1 for λ l E (- ∞,λ] and χ (l) (-∞,λ) = 0 otherwise, and the average is with respect to the joint eigenvalue distribution of the GUE, as well as to the evaluation of F N (λ;a) :(Π N l=1 (λ - λ l ) a ). Of particular interest are E N (λ;2) and F N (λ;2)X and their scaled limits, which give the distribution of the largest eigenvalue and the density respectively. Our results are obtained by applying the Okamoto τ-function theory of Painleve IV and Painleve II equations, for which we give a self contained presentation based on the recent work of Noumi and Yamada. We point out that the same approach can be used to study the quantities E N (λ; a) and F N (λ; a) for the other classical matrix ensembles

Preserving the Boltzmann ensemble in replica-exchange molecular dynamics.

2008-10-28

We consider the convergence behavior of replica-exchange molecular dynamics (REMD) [Sugita and Okamoto, Chem. Phys. Lett. 314, 141 (1999)] based on properties of the numerical integrators in the underlying isothermal molecular dynamics (MD) simulations. We show that a variety of deterministic algorithms favored by molecular dynamics practitioners for constant-temperature simulation of biomolecules fail either to be measure invariant or irreducible, and are therefore not ergodic. We then show that REMD using these algorithms also fails to be ergodic. As a result, the entire configuration space may not be explored even in an infinitely long simulation, and the simulation may not converge to the desired equilibrium Boltzmann ensemble. Moreover, our analysis shows that for initial configurations with unfavorable energy, it may be impossible for the system to reach a region surrounding the minimum energy configuration. We demonstrate these failures of REMD algorithms for three small systems: a Gaussian distribution (simple harmonic oscillator dynamics), a bimodal mixture of Gaussians distribution, and the alanine dipeptide. Examination of the resulting phase plots and equilibrium configuration densities indicates significant errors in the ensemble generated by REMD simulation. We describe a simple modification to address these failures based on a stochastic hybrid Monte Carlo correction, and prove that this is ergodic.

At the beginning of the ancient "Silk Road", traditional Chinese medicine resources (TCM resources) have long been integrated into it, and it was once the "important part" of the ancient "Silk Road" in Chinese history, benefited from this, the political connections was strengthened, the economic and trade was developed, and Chinese medicine culture was spread. Before Qing Dynasty, people took out the "silk" and brought back "herbs" on the "Silk Road", which enriched China's medicinal resources. While in the later Qing Dynasty and the period of the Republic of China, more scientific and technological methods were brought back from abroad, and this in turn enriched the medical research methods. With more than 2 000 years' development, China's boundaries have changed countless times, therefore the word "Foreign" has different meanings in different historical periods. The import, development and utilization of foreign TCM resources is different in different historical periods, at present, with the continuous enhancement of China's comprehensiv national strength，especially the "Belt And Road" strategy, the communication and import of TCM resources with countries that participating in the "Belt and Road" initiativ became much easier. In order to actively respond to the "Belt and Road" initiative promote the development and utilization of foreign medicinal resources; serve people from the countries participating in the "Belt and Road" initiative we sorted out the foreign TCM resources from different periods in ancient and modern China, and based on this, we proposed the strategy of import of foreign TCM resources under the new situation, those are: "three levels, four steps, one support and one key". And "three levels" refers to intelligence collection level, field investigation level, scientific research level, "Four steps" refers to the original identification research, safety evaluation research, functional positioning research and medicinal properties research; "One

China's traditional Peking Opera has four standard categories of roles: Sheng, Dan, Jing, and Chou, the singing vibrato of each displaying a different auditory effect. The audio and respiratory signals were recorded for two performers of the Qing Yi role, one of the Jing role, one of the Chou role, one of the Lao Sheng role, one of the Xiao Sheng role, and one of the Lao Dan role. The recordings gained eventually consisted of 24 representative songs from six roles. The rates and extents of vibrato, fundamental frequency, and rib cage signals were analyzed. Two findings were obtained: (1) the classical opera singing vibratos of China and Western countries are acoustically different from each other; and (2) in Peking Opera, the singing vibratos of different roles show significant acoustic differences.

Entanglement purification is to distill the high quality entanglement from the low quality entanglement with local operations and classical communications. It is one of the key technologies in long-distance quantum communication. We discuss an entanglement purification protocol (EPP) with spontaneous parametric down conversion (SPDC) sources, in contrast to previous EPP with multi-copy mixed states, which requires ideal entanglement sources. We show that the SPDC source is not an obstacle for purification, but can benefit the fidelity of the purified mixed state. This EPP works for linear optics and is feasible in current experiment technology.

We demonstrate both experimentally and theoretically that metallic gratings consisting of narrow slits become transparent for extremely broad bandwidths under oblique incidence. This phenomenon can be explained by a concrete picture in which the incident wave drives free electrons on the conducting surfaces and part of the slit walls to form surface plasmons (SPs). The SPs then propagate on the slit walls but are abruptly discontinued by the bottom edges to form oscillating charges that emit the transmitted wave. This picture explicitly demonstrates the conversion between light and SPs and indicates clear guidelines for enhancing SP excitation and propagation. Making structured metals transparent may lead to a variety of applications. References: Xian-Rong Huang, Ru-Wen Peng, and Ren-Hao Fan, Phys. Rev. Lett.

Overglaze decoration porcelain is an important category of ancient Chinese ceramics, which has significant artistic value and scientific value. Nondestructive analysis methods such as Raman spectroscopy and EDXRF were used to analyze the overglaze decorations on the Jingdezhen ceramic samples of Yuan, Ming and Qing Dynasty. The recipe and color mechanism of the overglaze pigments were discussed according to the chemical composition and phase composition analysis. The study found that dark red overglaze decorations of ancient Honglvcai, Wucai and famille rose in Jingdezhen are colored by hematite, yellow color is lead tin yellow, carmine decoration is colored by gold less than 0. 1 % in concentration, and green decorations are colored by bivalent copper ion. The result also indicates that the effective combination of Raman spectroscopy and EDXRF can play an important role in the deep research on ceramic artifacts, especially for the overglaze decoration pigments which are interveined each other.

This paper presents the characteristics of straw open burning-derived air pollution to understand its impact mechanism and take effective control measurements. In this study, PM2.5 emissions inventory from straw open burning was established at a high spatial resolution of 0.1° × 0.1° in Tianjin using geographic information systems (GIS) for the period of 2001-2012. PM2.5 emissions increased by 209.15% in the past nine years at an annual average rate of 23.24% from 2.95 Gg in 2002 to 6.17 Gg in 2010. WuQing District covering 13.17% of Tianjin land contributed to PM2.5 emission of 28.21% of total PM2.5 emissions from straw open burning.

Approaching Chinese Freedom: A Study in Absolute and Relative Values

Directory of Open Access Journals (Sweden)

David Kelly

2013-01-01

Full Text Available The rise of stability preservation to dominance in the political order coincided with a highly charged debate over “universal values” and a closely related discussion of a “China Model”. This paper analyses the critique of universal values as a “wedge issue” that is used to pre-empt criticism of the party-state by appealing to nationalism and cultural essentialism. Taking freedom as a case in point of a universal value, it shows that, while more developed in the West, freedom has an authentic Chinese history with key watersheds in the late Qing reception of popular sovereignty and the ending of the Maoist era. The work of Wang Ruoshui, Qin Hui and Xu Jilin display some of the resources liberals now bring to “de-wedging” universal values, not least freedom. They share a refusal to regard “Western” values as essentially hostile to Chinese.

Development and reproductive biology of the egg-pupal parasite, Fopius arisanus in Anastrepha suspensa, a new tephritid host

2000-01-01

Fopius (=Biosteres) arisanus (Sonan) (=Opius oophilus Fullaway) (Hymenoptera: Braconidae) is a solitary egg parasite (parasitoid) that attacks tephritid fruit fly (Diptera: Tephritidae) eggs and first instars (Haramoto 1953, Clausen et al. 1965, Harris and Okamoto 1991). It completes its development within the host's larva and pupa and emerges from the latter as an adult and as such, is an egg-pupal endoparasite. F. arisanus is known to attack at least seven tephritid fruit fly species (Wharton and Gilstrap 1983) and appears to be the only egg-pupal parasite of tephritids in the Western Hemisphere. It is considered to be the most successful of the parasites that attack the Oriental fruit fly, Bactrocera dorsalis (Hendel) and the Mediterranean fruit fly (Medfly), Ceratitis capitata (Weidmann) in Hawaii (Knipling 1995), resulting in 74-92% of total parasites recovered from both host species (Wong and Ramadan 1987). However, in Malaysia, Palacio et al. (1992) found that F. arisanus was outcompeted by the larval endoparasite, Diachasmimorpha longicaudata (Ashmead) (Hymenoptera: Braconidae) in multiple parasitised B. dorsalis. While several larval parasites of tephritids had been cultured successfully in the laboratory (Ramadan 1991) and utilised in inundative release programmes, F. arisanus proved difficult to maintain in culture. In recent years, a laboratory strain of F. arisanus (termed the 'Harris strain') has been established on B. dorsalis (Harris and Okamoto 1991). Efforts are currently in progress to mass rear this strain on the Medfly and other tephritid pests. F. arisanus was first released into Florida from Hawaii in 1974-75 as a biological control agent against the Caribbean fruit fly (Caribfly) Anastrepha suspensa (Loew) (Diptera: Tephritidae) but this was unsuccessful (Baranowski et al. 1993). Interestingly, it was also introduced into Costa Rica from Hawaii and was subsequently reared from puparia of Anastrepha spp. (Wharton et al. 1981), indicating its

Chen, Q

2017-01-28

Ethyl ether was the first accepted effective general anaesthetic. It was introduced into China by an America missionary, Dr. Peter Parker. This was one of the historical events of medical communication between China and the West. In the records of the first operation with ether, however, Dr. Parker unusually omitted the patient's medical record number and the date of the operation, while those of other operations with ether anesthetics were all available. This was very unusual for a doctor like Peter Parker who always recorded every important case in detail in the hospital reports. It seems that he deliberately rather than carelessly omitted the information for some reasons. Based on the analysis of Parker's reports, a conclusion is made that the anesthetic effect of the case was actually ineffective. Furthermore, possible answers to this are outlined and question by discussion based on the situation that Parker faced in the late Qing era.

Hanson, Marta

2017-09-01

Argument This article analyzes for the first time the earliest western maps of diseases in China spanning fifty years from the late 1870s to the end of the 1920s. The 24 featured disease maps present a visual history of the major transformations in modern medicine from medical geography to laboratory medicine wrought on Chinese soil. These medical transformations occurred within new political formations from the Qing dynasty (1644-1911) to colonialism in East Asia (Hong Kong, Taiwan, Manchuria, Korea) and hypercolonialism within China (Tianjin, Shanghai, Amoy) as well as the new Republican Chinese nation state (1912-49). As a subgenre of persuasive graphics, physicians marshaled disease maps for various rhetorical functions within these different political contexts. Disease maps in China changed from being mostly analytical tools to functioning as tools of empire, national sovereignty, and public health propaganda legitimating new medical concepts, public health interventions, and political structures governing over human and non-human populations.

School education had gradually become the mainstream of medical education at the turn of the Qing Dynasty and Republican period. In Tianjin, there were western medical education, including the Peiyang Medical College, Army Medical College, and Lu's Medical School, whereas, there was no traditional medical school at all. To check this defect, two private TCM medical schools, the Learning School of TCM, and the Tianjin TCM Institution were set up by Chen Zedong and Gu Jinren respectively through persistent endeavor. Meanwhile, correspondence school of TCM were established by Zhang Xichun, Wei Jiaqian, and Ma Leshan. Though more TCM schools were planned, including Tianjin Private School of TCM by Lu Zongren and Qian Boquan, North China Professional TCM School by Zhang Yinqi and other colleagues, TCM Professional School by Zhang Dianju and the Tianjin Private Acu-Moxibustion School by Zhang Lihui, etc. All these did make their contributions to the training of TCM talents in modern times.

Full Text Available According to precise and scientific literature that recorded, Chinese tea culture has a documented history of more than 1700 years. During which period, Yuan Dynasty was considered a crucial turning-point with great changes. The current tea culture in China is an adoption and innovation of Ming and Qing dynasty, especially in the form of processing technology. For those elements inherited from Tang and Song dynasties, however, they were more directly adopted systematically by Japan. Ever since powdered tea culture from Song dynasty was accepted in Japan, Jianzhan, the tea bowl that gained renowned reputation in the Song tea culture was also introduced and became tenmoku (tianmu after localization. As the transformation of Chinese tea culture ended in Japan, Japanese tea culture of wabi-cha was shaped after the tenmoku’s obvious decline in value. Jianzhan’s prosper, and tenmoku’s emergence and transition, all proved a definitive impact from intangible culture.

It was intended to elucidate characteristics of distribution of damages caused by an earthquake which occurs directly below an urban area. Therefore, numerical simulation using the pseudo-spectral method was performed on characteristics of seismic wave propagation in non-homogenous media composed of rock beds and sediment beds, and of seismic wave amplitudes on ground surface. The simulation has utilized information on underground structures disclosed by using the latest physical exploration method. The underground structure model assumed a two-dimensional model hypothesizing presence of upper, middle and lower beds in the Osaka bed group on granite, using as reference the information on S-wave velocity underground structure revealed by the microtremor exploration method. With an objective to elucidate characteristics of distribution of collapse ratio in the area from 8-chome, Okamoto, Higashinada Ward, Kobe City to 2-chome of Sakanasaki Minamicho, as damages suffered from the Hyogo-ken Nanbu Earthquake, a simulation has been performed varying the structure model based on the results derived by the microtremor exploration method and the reflection method. As a result, it was shown that the characteristics of the maximum amplitude distribution of displacement of ground surface, velocity and acceleration agree well with those of the collapse ratio distribution, and that the simulation using the pseudo-spectral method is an effective means to analyze the ground surface collapse ratio distribution. 5 refs., 3 figs.

The development of large size emulsion chambers has been made to study very high energy events. For this purpose, the chambers with exchangeable light sensitive layers are considered. The chambers have large gap for the exchange. In this case, it becomes hard to determine the energy of cascade shower. In this report, the authors describe on the experimental examples observed at Mt. Chacaltaya. The effect of a gap was investigated by these examples, and the simulation method by Okamoto and Shibata was applied to the chamber. The chamber used for the observation consisted of the top chamber of 11 c.u. and the bottom chamber of 15 c.u. There was a large gap of 170 cm between two chambers. Twelve showers in three families observed by this system were analyzed. The difference between the blackness in the top and bottom films was studied quantitatively. The blackness was calibrated for the electron density. Four methods of energy determination were studied. Among them, a method to employ the sum of the maximum blackness of a top film and that of a bottom one was used for the analysis. This method seemed to be more reliable than the old method. It was found by a simulation calculation that the recovery of shower in the bottom chamber was seen not only by hardrons but also by gamma-ray. (Kato, T.)

Multiscale functions, scale dynamics, and applications to partial differential equations

Modeling phenomena from experimental data always begins with a choice of hypothesis on the observed dynamics such as determinism, randomness, and differentiability. Depending on these choices, different behaviors can be observed. The natural question associated to the modeling problem is the following: "With a finite set of data concerning a phenomenon, can we recover its underlying nature? From this problem, we introduce in this paper the definition of multi-scale functions, scale calculus, and scale dynamics based on the time scale calculus [see Bohner, M. and Peterson, A., Dynamic Equations on Time Scales: An Introduction with Applications (Springer Science & Business Media, 2001)] which is used to introduce the notion of scale equations. These definitions will be illustrated on the multi-scale Okamoto's functions. Scale equations are analysed using scale regimes and the notion of asymptotic model for a scale equation under a particular scale regime. The introduced formalism explains why a single scale equation can produce distinct continuous models even if the equation is scale invariant. Typical examples of such equations are given by the scale Euler-Lagrange equation. We illustrate our results using the scale Newton's equation which gives rise to a non-linear diffusion equation or a non-linear Schrödinger equation as asymptotic continuous models depending on the particular fractional scale regime which is considered.

This was compared to 22 cases of HBVAA at AA onset as well as the associated IST outcomes.Results: Nine patients with SNHAA developed severe aplastic anemia, with a median age of 18 years. After IST, six (60% of the SNHAA patients achieved complete remission and two achieved partial remission. The patients with HBVAA had a total response rate of 82.3%. The disease recurred in two HBVAA patients. No statistically significant differences were observed in response rate, mortality, and recurrence rate between both groups. As compared with HBVAA, patients with SNHAA had a shorter interval from the acute episode of hepatitis to AA onset (4 months versus 92 months, P=0.00, a quicker response to IST (2.5 months versus 4.5 months, P=0.018, a lower proportion of bone marrow hematopoietic tissues (20.6% versus 23.6%, P=0.03, and lower white blood cell and absolute neutrophil count (0.8×109/L versus 1.23×109/L and 0.26×109/L versus 0.58×109/L, P=0.026 and P=0.0009, respectively. No significant liver damage or hepatitis B fulminant infection was observed in either group during the follow-up. Conclusion: The prevalence of SNHAA is 3.01%. SNHAA often presents as severe AA and responds to IST quickly

The Setaria genus is increasingly of interest to researchers, as its two species, S. viridis and S. italica, are being developed as models for understanding C4 photosynthesis and plant functional genomics. The genome constitution of Setaria species has been studied in the diploid species S. viridis, S. adhaerans and S. grisebachii, where three genomes A, B and C were identified respectively. Two allotetraploid species, S. verticillata and S. faberi, were found to have AABB genomes, and one autotetraploid species, S. queenslandica, with an AAAA genome, has also been identified. The genomes and genome constitutions of most other species remain unknown, even though it was thought there are approximately 125 species in the genus distributed world-wide. GISH was performed to detect the genome constitutions of Eurasia species of S. glauca, S. plicata, and S. arenaria, with the known A, B and C genomes as probes. No or very poor hybridization signal was detected indicating that their genomes are different from those already described. GISH was also performed reciprocally between S. glauca, S. plicata, and S. arenaria genomes, but no hybridization signals between each other were found. The two sets of chromosomes of S. lachnea both hybridized strong signals with only the known C genome of S. grisebachii. Chromosomes of Qing 9, an accession formerly considered as S. viridis, hybridized strong signal only to B genome of S. adherans. Phylogenetic trees constructed with 5S rDNA and knotted1 markers, clearly classify the samples in this study into six clusters, matching the GISH results, and suggesting that the F genome of S. arenaria is basal in the genus. Three novel genomes in the Setaria genus were identified and designated as genome D (S. glauca), E (S. plicata) and F (S. arenaria) respectively. The genome constitution of tetraploid S. lachnea is putatively CCC'C'. Qing 9 is a B genome species indigenous to China and is hypothesized to be a newly identified species. The

Cloud is one of the main processes in the climate system and especially a large feed back agent for Arctic warming amplification (Yoshimori et al., 2014). From this reason, observation of polar cloud has been emphasized and 95 GHz cloud profiling radar in high precision was established at Ny-Ålesund, Svalbard in 2013 as one of the basic infrastructure in the GRENE (Green Network of Excellence Program) Arctic Climate Change Research Project. The radar, "FALCON-A", is a FM-CW (frequency modulated continuous wave) Doppler radar, developed for Arctic use by Chiba University (PI: T. Takano) in 2012, following its prototype, "FALCON-1" which was developed in 2006 (Takano et al., 2010). The specifications of the radar are, central frequency: 94.84 GHz; antenna power: 1 W; observation height: up to 15 km; range resolution: 48 m; beam width: 0.2 degree (15 m at 5 km); Doppler width: 3.2 m/s; time interval: 10 sec, and capable of archiving high sensitivity and high spatial and time resolution. An FM-CW type radar realizes similar sensitivity with much smaller parabolic antennas separated 1.4 m from each other used for transmitting and receiving the wave. Polarized Micro-Pulse Lidar (PMPL, Sigma Space MPL-4B-IDS), which is capable to measure the backscatter and depolarization ratio, has also been deployed to Ny-Ålesund in March 2012, and now operated to perform collocated measurements with FALCON-A. Simultaneous measurement data from collocated PMPL and FALCON-A are available for synergetic analyses of cloud microphysics. Cloud mycrophysics, such as effective radius of ice particles and ice water content, are obtained from the analysis based on algorithm, which is modified for ground-based measurements from Okamoto's retrieval algorithm for satellite based cloud profiling radar and lidar (CloudSat and CALIPSO; Okamoto et al., 2010). Results of two years will be shown in the presentation. Calibration is a point to derive radar reflectivity (dBZ) from original intensity data

Sheng＇en Temple of Guangfu in Suzhou enjoyed a special relationship with the care of the royal family of Ming Dynasty.During the 14th year of rule by Emperor Hongwu（Zhu Yuanzhang） of Ming Dynasty（1381 A.D.）,Zhu Yuanzhang called in the monks of the temple,wrote a calligraphy scroll for the temple and granted lots of materials.Moreover,he wrote several poems for the temple.During the 8th year of rule by Emperor Zhengtong（Zhu Qizhen） of Ming Dynasty（1443 A.D.）,the emperor awarded the temple a board inscribed with the ＂Royal Grace and Longevity Buddhist Temple＂.After the ＂Tumu Fortress Incident＂ and the restoration of Zhu Qizhen,the emperor awarded again the temple a board inscribed with the ＂Royal Grace Buddhist Temple＂ in the 3rd year of rule by Emperor Tianshun（1459 A.D.）.Emperor Kangxi of the Qing Dynasty made several southern tours during the intervals of the warfare and foreign affairs with Russia in the north.In the 28th year of his rule（1689 A.D.）,Kangxi arrived at Dengwei Hill in Guangfu of Suzhou and stayed at Sheng＇en Temple during his second southern tour.He granted the temple his calligraphy work of ＂Pine,Breeze,Brook and Moon＂,200 liang state treasury gold and several poems that he wrote for the temple.Kangxi＇s behavior implies his comparison and competition with the outstanding emperors of the former dynasty.More importantly,he expected to manifest the ＂Royal Grace＂ of the Qing Dynasty in the temple that boasted of the grace of the former dynasty of Ming.His behavior is also a way to resolve the resentment of the monks and the laymen toward the Qing Dynasty.%苏州光福圣恩寺是一座与明代皇家有着特殊关系且沐浴着明代皇家＂圣恩＂的寺院。明初洪武十四年（1381）,明太祖朱元璋召见该寺寺僧,亲自书写条幅送之,并赐予丰厚的赏赐;同时,朱元璋还为该寺写下数首诗作。明正统八年（1443�

A Breakthrough for Strengthening Tusi Studies

Li Liangpin; Peng Furong

2016-01-01

Following the inscription of China’s Tusi ( native officials ) relics onto the list of world cultural heritage in 2015 , Tusi studies has already become a current topic. However, if we ignored the numerous and complicated historical events, the tremendous amount of historical materials and cases with different characteristics, it is difficult to realize a theoretical breakthrough and academic in-novation. Hence, if the academic world intends to find a new breakthrough in Tusi studies, enough attention should be given to the analysis of past e-vents, digging out historical materials, and case studies—only by which can Tusi studies be strengthened. 1 . Analysis of past events Scholarly research of the Tusi in the past has paid more attention to the system, culture ,and ap-plication of Tusi relics for inscription onto the list of world cultural heritage, but has ignored analysis of significant events. Due to the influence of the political right, economic benefit, and cultural in-filtration, there had always been competition be-tween the central government and the Tusi regime during the Yuan, Ming and Qing dynasties. When some conflicts could not be resolved through nego-tiation, large-scale events or battles were the re-sult. Judging from current studies on every small or large battle between the central government and a Tusi regime, we can see that scholars always focus their studies on the background, process, result, historical influence and related evaluations. Up to now, no scholars have written a monograph of these big events closely related to the Tusi, which is doubtlessly a pity when it comes to Tusi studies. We think that three issues should be noticed while analyzing big events related to the Tusi:1 ) taking the overall situation into consideration; 2 ) having theoretical sight; and 3 ) having a theoretical awareness. 2 . Uncovering historical materials The historical materials are especially impor-tant for the study of the Tusi system or Tusi issues

It is the key point of quantitative research on agricultural non-point source pollution load, the estimation of pollutant concentration in agricultural drain. In the guidance of uncertainty theory, the synthesis of fertilization and irrigation is used as an impulse input to the farmland, meanwhile, the pollutant concentration in agricultural drain is looked as the response process corresponding to the impulse input. The migration and transformation of pollutant in soil is expressed by Inverse Gaussian Probability Density Function. The law of pollutants migration and transformation in soil at crop different growth periods is reflected by adjusting parameters of Inverse Gaussian Distribution. Based on above, the estimation model for pollutant concentration in agricultural drain at field scale was constructed. Taking the of Qing Tong Xia Irrigation District in Ningxia as an example, the concentration of nitrate nitrogen and total phosphorus in agricultural drain was simulated by this model. The results show that the simulated results accorded with measured data approximately and Nash-Sutcliffe coefficients were 0.972 and 0.964, respectively.

Full Text Available With the rise of China's status on international stage as a result of its economic development there is an increasingly audible voice of Chinese cultural nationalism. More and more educators and intellectuals are calling for the revival of Chinese traditional culture values. However, the very issues of who are the Chinese and what are traditional Chinese cultural values present a huge dilemma. The debates on a recent a TV program "General Shi Lang" consist a good case to illustrate this dilemma. Shi Lang was a general of the last days of the Ming Dynasty, but had surrendered to the Manchu Qing dynasty invaders and fought for the Machus take over Taiwan from a Chinese ruler. The debates show that the dilemma has its cause in at least three issues. First, it is not at all obvious who should be categorized as Chinese. Secondly, it is not at all obvious what Chinese cultural values are. And finally it is the issue of evaluation of traditional values against the universal claim of the values of liberal democracy.

Full Text Available This paper highlights contemporary China’s long-term continuities with the historical EastAsian developmental path in relation to its post-1978 revival of market-economy traditions. Therevival of market economy traditions does not exemplify the unfolding of processes associatedwith the “one-size-fits-all” Washington Consensus. Rural land reforms were driven from belowand strongly influenced policy changes from above. Neither rural nor urban land use relationssuggest a more general unfolding of neoliberal processes of capitalist accumulation bydispossession. Contemporary Chinese land relations reflect the effects of continuities withhistorical East Asian regional traditions more strongly than do some discontinuities andruptures that emerged in the conjuncture of the mid-1980s. These continuities remain moreimportant in understanding the future of the China-led East Asian region. Like the Ming andQing dynasties, China’s Party-State is sharply focused on problems of governance. Retaininglegitimacy and recreating a welfare state to promote harmonious development rather thangrowth fetishism appears to characterize China’s current trajectory.

Linagliptin, a member of dipeptidyl peptidase-4 inhibitor class, is unique in its nonlinear pharmacokinetics with the characteristics of rapid attainment of steady state, little accumulation, predominantly nonrenal route of elimination, prolonged terminal half-life, and sustained inhibition of dipeptidyl peptidase-4 enzyme. No clinically relevant difference in pharmacokinetics was observed between Asians and non-Asians. The management of type 2 diabetes is increasingly challenging with the progression of disease, especially with the requirements of minimal hypoglycemia, weight gain, fluid retention, and other adverse effects. Linagliptin was efficacious and well-tolerated in Asian type 2 diabetes patients with or without renal or hepatic dysfunctions, comparable to that in Caucasians. This review will focus on the usage of linagliptin in clinical studies in Asians. Keywords: linagliptin, Asians, type 2 diabetes

In order to classify the Otani Collection's Dunhuang and Turfan manuscripts, their trace elements were analyzed by PIXE. The paper samples of these manuscripts were fallen off when they were photographed for a CD-ROM catalog. These samples were very small and their size was less than several millimeters. In addition, some paper fragments dating from the late Edo-era of Japan and the late Qing Dynasty of China, and modern Japanese handmade paper were analyzed using PIXE and NAA. Quite interesting results were obtained when analyzing the trace elements - Na, Mg, Al, Si, S, Cl, K, Ca, Sc, Mn, Fe, Cu, Zn, As, Br, Sr, Ba, Pb, La, Sm. It was found that Dunhuang and Turfan papers of the Otani Collection were characterized by its highest iron and bromine content. The reason of the highest iron content probably originates in their making process and/or depends on their preservative environment. On the other hand, it became clear as for the highest bromine content that the origin is from fumigation of methyl bromide. (author)

Vertical transmission of infectious hematopoietic necrosis virus in sockeye salmon (Oncorhynchus nerka): Isolation of virus from dead eggs and fry

Mulcahy, D.; Pascho, R.J.

1985-01-01

The control of epizootics of infectious haematopoietic necrosis (IHN) virus in salmonid fishes is presently based on examination and certification of adult brood fish to prevent the introduction of virus-infected eggs into hatcheries (Canadian Fisheries and Marine Service 1976; McDaniel 1979). This strategy is based on the assumption that the virus is vertically transmitted in association with the gametes. However, evidence for vertical transmission of IHN virus is circumstantial, based mostly on the appearance of the disease outside the enzootic area (the west coast of North America) in fish hatched from eggs obtained from within that area (Plumb 1972; Holway & Smith 1973; Wolf, Quimby, Pettijohn & Landolt 1973; Sano, Nishimura, Okamoto, Yamazaki, Hanada & Watanabe1977; Carlisle, Schat & Elston 1979). An indirect demonstration of vertical transmission was made by placing known virus-free fish in the water above and below raceways containing fish that suffered an IHN epizootic in an effort to eliminate waterborne virus as a source of infection (Wingfield & Chan 1970). The fish placed below the raceway developed IHN, due to waterborne virus released from the affected fish in the raceway, but the fish placed above the raceway failed to develop IHN. These results suggested that the source of infection of the fish in the raceway was not the water supply, although it is possible that the virus was no longer present in the water supply at the time the sentinel fish were exposed to the water.

The overall extent of evidence-based culturally responsive health education programs targeting ethnic minority groups in Hawai'i is limited. The few that do exist were adapted from models developed with other majority ethnic groups in mind and may not always be appropriate for Native Hawaiian or Pacific Islander youth (Okamoto et al. in J Alcohol Drug Educ 54(1):56-75, 2010; Helm and Baker in J Ethn Cult Divers Soc Work 20(2):131-149, 2011; Po'a-Kekuawela et al. in J Ethn Cult Divers Soc Work 18(3):242-258, 2009). The need for a culturally responsive, evidence-based health curriculum is clear considering the large disparities reported among Hawaiian youth in health, academic achievement, and other identified risk factors. School-based health interventions are an opportunity not only to improve the physical well being of students, but also to increase their ability to learn and succeed in school. The University of Hawai'i at Manoa-Center on Disability Studies (UH-CDS) received a highly competitive grant from the US Office of Adolescent Health to develop a teen pregnancy and sexually transmitted infection (STI) prevention curriculum for Hawai'i middle school youth. The authors will detail a collaborative process that led to a culturally responsive sexual health curriculum for middle school youth designed to meet the rigorous standards of an evidenced-based review and more importantly reduce teen pregnancies and STI transmission.

2013-12-01

Nursing and teaching are considered risk professions with high levels of stress and burnout. Dual-qualification nursing teachers (DQNT) are nurses who both teach and practise. These nurses face additional stress. This study explored the stressors of DQNT in the Chengdu-Chongqing Economic Zone of China. This qualitative study used in-depth, open-ended interviews. The interview responses were analysed using a grounded theory approach. The participants in this study included 21 DQNT from 5 teaching hospitals in the Chengdu-Chongqing Economic Zone of China. The results indicated that heavy workload, personal safety, inadequate pay, role overload, and poor working environment are stressors of DQNT. Furthermore, Chinese DQNT face violence from patients and students. The study provides a theoretical basis to help DQNT to cope with stress. Copyright © 2013 Elsevier Ltd. All rights reserved.

Shrews in Strange Tales from a Chinese Studio not only are great in number but also forms a complete picture of its group. In the past, studies on the shrews in this novel were from such aspects as views on marriage and religions, and the most typical views were to redress customs, reflect social practice and patri-archy projection. These theories, however, fail to satisfactorily explain the prevailing of shrews in this novel. Under the unique circumstances of Ming and Qing Dynasty, Pu Songling, the novelist, was deeply influenced by the ideology of “distinguishing Central China from its neighbors”, which has a profound influence on his literary works. As literacy inquisition occurred repeatedly in Qing Dynasty, writers had to seek a roundabout way to express his feeling. The group of shrews in Strange Tales from a Chinese Studio was thus formed. The novelist found his voice in the shrews and the shrews carry with them more symbolic meaning than realistic meaning. To know the symbolic meaning of the shrews helps readers understand Pu Songling and his literary recreation.%《聊斋志异》中的悍妇不仅数量众多，且可构成一体系完备的悍妇群。对《聊斋志异》悍妇的研究，多从婚姻观、宗教观角度分析，以“正风俗”、现实反映论以及男权投射论最为典型。然这些理论都不能尽解《聊斋志异》悍妇盛行之因。在明末清初特殊的社会背景下，蒲松龄深受“夷夏之辨”的思想意识影响，并深深影响其《聊斋志异》的创作；但清代文字狱迭发，抒发自己家国情怀，只能以迂回委婉的方式表达。悍妇便是这一家国情怀抒发的载体之一，其象征意义大于现实意义。了解悍妇的象征意义，对研究蒲松龄《聊斋志异》的创作有一定的意义。

Two rare species of the family Tylenchidae are described and illustrated based on morphological and morphometric characters. Scanning electron microscope (SEM) studies provided details of anterior end structures, helpful in generic identification of the studied populations. Discotylenchus biannulatus n. sp. is characterized by its dorso-ventrally flattened smooth cephalic region having two proximal annuli and a rectangular perioral disc, short longitudinal amphidial slits, lateral field with four incisures, stylet 9-10 μm long, with the conus shorter than half the total stylet length and with posteriorly directed knobs, well-developed median bulb, mono-prodelphic reproductive system with rounded empty spermatheca and short postvulval uterine sac (PUS), and filiform tail with pointed end. It is compared with other species of Discotylenchus having four lines in the lateral field. The Iranian population of Labrys chinensis is characterized by its long and slender (a = 45.2-57.2) body, smooth rounded cephalic region and an offset disc-like apical labial plate, short longitudinal lateral amphidial slits, lateral field with two incisures, moderately developed stylet with the conus less than half the total length and posteriorly directed knobs, median bulb fusiform with distinct but weak valve, gradually joining the isthmus, vulva at 57.2-59.1% with small flaps, elongate conoid tail, uniformly and slightly narrowing toward end with broadly rounded terminus and rare males. The minor morphological differences of the recovered population with the type population are discussed.

There are two different records, namely,"vulnerability to dampness in autumn"and"dryness prevailing"in autumn, in the Neijing ( Inner Canon ). In the Jin and Yuan Dynasties, Liu Wansu supplemented the pathogenesis of dryness pathogen, whereas Wang Andao explained the contradictory records in the Neijing . In the Qing Dynasty, Yu Chang definitely challenged the theory"vulnerability to dampness in autumn"of the Neijing ,triggering a debate on the recognition of"drying dampness". In fact, Yu Guopei was the initiator of"theory of drying dampness", who discussed the nature of Yin and Yang of"drying dampness"based on the laws of correspondence between human body and natural environment, elucidating that drying dampness should be the root of both exogenous disease and internal damage, and elaborating the etiology and pathogenesis of"drying dampness", the diagnosis and the nature of the drugs for drying dampness. Shi Shoutang inherited Yu's theory and made a further development. In modern times, some scholars advocated that"drying dampness"should be consideredalong with Yin and Yang, superficies and interior, excess and deficiency, cold and heat, as the guiding principle for syndrome differentiation.

Full Text Available Replantation of the lower extremity has controversial indications but nevertheless it may be considered in carefully selected patients who present early and are expected to show good functional recoveries. Here we present a successful replantation in a 3-year-old boy who has made excellent recovery with no functional deficit evident at 12 years of follow-up. He sustained a traumatic amputation at the level of distal tibia when he fell of a “Qing Qi” (motorcycle rickshaw. Replantation was attempted at 8 hours cold ischemia time with the tibia shortened 4 cm and all tendons, vessels, and nerves repaired. Patient required a second procedure during the same hospital stay for skin coverage. Patient made good recovery with ambulation without support at 6 months, less than 3 cm limb length discrepancy, plantar and dorsiflexion power 4/5, and recovery of sensation over the foot. Now at 12 years of follow-up patient has a normal gait and has integrated into society with no functional deficit. Considering the functional outcome of our case, replantation should be attempted whenever possible and feasible especially in children.

We investigate the effect of Zn doping on the dielectricity and ferroelectricity of a series of polycrystalline Sr0.9-xZnxBa0.1TiO3 (0.0% ≤ x ≤ 5.0%) ceramics. It is surprisingly observed that the Zn doping will produce the multifold polar states, i.e., the Zn-doped ceramic will convert a reduced polar state into an enhanced polar state, and eventually into a stabilized polar state with increasing the doping level x. It is revealed that in the background of quantum fluctuations, the competition between the Zn-doping-induced lattice contraction and the Ba-doping-induced lattice expansion is responsible for both the reduced polar state and the enhanced polar state coming into being. Also, the addition of the antiferrodistortive effect, which is the antipolar interaction originating from the opposite tilted-TiO6 octahedra rotation, represents the core physics behind the stabilized polar state.

Full Text Available In this article, we analyze the relation among educational reforms and teachers’ work, and emotions. This study was conducted with a public school English teacher, in Minas Gerais. The aim was to verify the role that contextual factors play in the production of emotions, and detect the emotions that influence her practice with students, colleagues, and school managers. The theoretical framework was based on studies about educational reforms and teachers’ work (AUGUSTO, 2005; HYPOLITO; VIEIRA; PIZZI, 2009; DUARTE; AUGUSTO, [s.d.], the relationship between emotions and the process of teaching and learning languages (HARGREAVES, 2000; ZEMBYLAS, 2002, 2003; ARAGÃO, 2008; DAY; QING, 2009; SHUTZ; ZEMBYLAS, 2009; COWIE, 2011; RIBEIRO, 2012. We used a semistructured questionnaire and a narrative interview as data collection instruments. The analysis has pointed out poor work condition, crowded classrooms, poor physical and technological structures, strict school curriculum, students’ indiscipline, and the institution pessimistic atmosphere as frustrating, stressful, and de-motivating factors. These results indicate the need to create alternative ways of school workplaces organization, and to modify the way people interact in schools. They also suggest the need of educators to participate in the design and implementation of educational reforms.

Compared with herbal drugs, medicine processed from animals (animal medicine) was thought to have more bioactive substances and higher activities. Biotransformation effect often plays an important role in their effect. However, researches about effect of animal medicine on diabetic nephropathy and applying animal medicine as natural bio-transformer were seldom reported. The purpose of this paper was to reveal the use of Bombyx Mori L. on diabetic nephropathy from ancient to modern times. The classical literature indicated that Saosi Decoction (), which contains Bombyx Mori L. or silkworm cocoon, was applied to treat disorders congruent with modern disease diabetic nephropathy from the Ming to Qing Dynasty in ancient China. Modern studies showed that Bombyx Mori L. contains four main active constituents. Among these, 1-deoxynojirimycin (1-DNJ) and quercetin showed promising potential to be new agents in diabetic nephropathy treatment. The concentrations of 1-DNJ and the activities of quercetin in Bombyx Mori L. are higher than in mulberry leaves, because of the biotransformation in the Bombyx Mori L. body. However, these specifific components need further human and mechanistic studies to determine their therapeutic potential for this challenging condition.

Although there is a long history of consanguineous marriage in China, information on its prevalence is very limited. The Man (Qing) dynasty ruled China for over 250 years, but no consanguinity studies have been reported on this important population. The objective of the present investigation was to determine the present-day level of consanguineous marriage in the Man community, and to compare the data with existing consanguinity information on other Chinese populations. The study was conducted in a group of 11 rural Man communities in the north-eastern Chinese province of Liaoning. Household-based interviews were conducted by local staff on 513 couples, 418 of whom were Man with another 95 Man-Han inter-ethnic marriages. Basic pedigrees were constructed to determine the biological relationship between each set of spouses. Thirty of the 418 couples were in a consanguineous union, with a mean coefficient of inbreeding alpha = 0.0012. The small population sizes of the study may have contributed to the spatial variation in the patterns of inbreeding. Across generations there was a reduction in consanguineous marriages and an increase in inter-ethnic unions, which paralleled changes in civil marriage regulations.

Background: The firing techniques of producing underglaze copper red porcelain emerged in the Yuan dynasty and reached its maturity during the Ming and Qing Dynasties in Jingdezhen city. The technique of producing underglaze red porcelain was sensitive to the firing temperature and atmosphere, so it was very hard to produce and also difficult to display red color under the surface successfully. Purpose and Methods: The micro SR-XRF technique was employed to analysis a piece of sherd of underglaze copper red porcelain of early Ming dynasty. The Chemical compositions of glaze and color areas were presented, and the elemental contents in different color areas were obtained by using line-scanning techniques. Results: Some elements such as As and Pb were contained in raw materials, and the content of Cu had obviously increased with the color changing from gray to red. The results indicated that the nature mineral possibly used as the pigment for underglazed copper red porcelain coloration, and the color appearance also depends on the amount of copper in the pigments contained. Conclusions: This paper presents the advantage of the synchrotron radiation XRF technology and contributes to the science evidences for the Chinese ancient porcelain handcraft research. (authors)

In the late Qing Dynasty, following the appearance of the Chinese medicinal materials industry trade association of Kunming, the "master agreement" as a professional regulation, also implemented, marking the beginning of the contractualization and institutionalization of apprentice education in Yunnan. The contents and implementation of the "master agreement" was organized by the Chinese medicinal materials industry trade association of Kunming and its craft union. The apprentice education in Kunming traditional Chinese medicinal industry has the following characteristics: expanding the source of talent; adepting at agricultural production of the accorded apprentice; conforming to the conditions of human manipulation of Chinese traditional medicine; being in line with the characteristics and rules of Chinese medicine skills taught by oral narration and tacit understanding; unity of the medical and pharmaceutical professionals; and non-governmental organization. Apprentice training had trained a number of medical talents, and promoted the transformation of manual workshop to industrialization in Kunming. Apprentice education had catalyzed the establishment of specialized shops selling patent medicines exclusively to separated from those running both crude drugs and patent medicines, to form a set of effective teaching system, thus exerting profound influence on later generations.

Fuja, R.; Grelick, A.E.; Meyer, D.

1997-01-01

The APS linac beam energy must be stable to within ±1% to match the energy acceptance of the positron accumulator ring. The klystron pulse modulators must therefore provide a pulse-to-pulse repeatability of 0.1% in order for the beam to have the required energy stability. The modulators have had difficulty achieving the necessary repeatability since the pulse forming network (PFN) charging scheme does not include a deQing circuit. Several of the major charging circuit components are also less reliable than desired. In order to increase operating reliability and to improve pulse-to-pulse stability, it is planned to replace the high voltage power supplies in all modulators with constant-current power supplies. A new modulator charging supply that contains two EMI series 303 constant-current power supplies was constructed. Each of these EMI supplies delivers 1.5 A at up to 40 kV. One supply is sufficient for linac operation at up to 45 Hz, and two supplies in parallel enable linac operation at the nominal rf repetition rate of 60 Hz. This paper discusses test results from the new modulator, and also describes the existing modulators and their performance limitations

Prevention and Care Programs Addressing the Growing Prevalence of Diabetes in China.

Yin, Junmei; Kong, Alice P S; Chan, Juliana C N

2016-12-01

According to a 2010 national survey, 11 % of adults in China have diabetes, affecting 109.6 million individuals. The high prevalence of diabetes has been attributed to the aging of the population, the rapid adoption of energy-dense foods, and a reduction in physical activity. Collectively, these secular changes have created an obesogenic environment that can unmask diabetes in subjects with a genetic predisposition. The growing prevalence of maternal obesity, gestational diabetes, childhood obesity, and early-onset disease can lead to premature morbidity and mortality. Rising to meet these public health challenges, researchers in China have conducted randomized studies to demonstrate the benefits of lifestyle modification in preventing diabetes (the Da Qing Study), as well as that of team-based integrated care, using multiple strategies including peer support and information technology, in order to reduce hospitalizations, cardiovascular-renal complications, and premature deaths. With growing evidence supporting the benefits of these diabetes prevention and management programs, the next challenge is to use policies and systems to scale up the implementation of these programs through raising awareness, building capacity, and providing resources to reduce the human and socioeconomic burden of diabetes.

Full Text Available Liaozhai Zhiyi is a compilation of short stories created by the Qing Dynasty novelist, Pu Songling. The main concept is not centered on regular ghost stories, but the author told a story on real life and the fantasy world by describing realities of society life in the feudal era. The author, through stories in Liaozhai Zhiyi, analyses social reality in their education, politics, love, economic and moral aspects. The author of Liaozhai Zhiyi uses of a lot of stories concerning fox spirits, ghosts, and other types of spirits in portraying his critics and anger towards incidents happening in feudal China. Analysis shows that Liaozhai Zhiyi broadly depicts social reality happening in feudal era in education, politics, love, economic and moral aspects. Liaozhai Zhiyi also criticizes the corrupt government official examination scheme, and the crime and decadence of the feudal government. In contrast, the stories also praised the freedom of young men and women seeking love in marriage, endorsing young men and women to reject arranged marriages, showing women in the economic independence and social advancement, and summed up the lessons of social life.

Based on the data previously collected during the Humidity Exchange over the Sea Main Experiment (HEXMAX), the methods used to parameterize aerodynamic roughness (z0), friction velocity (u*), and the neutral drag coefficient (CDN) under moderate wind speed conditions originally proposed by Gao et al. (2006) were extended by using the nondimensional significant wave height (gHs/u*2 or gHs/U10N2) instead of wave age (cp/u* or cp/U10N), where g is the acceleration of gravity, Hs is the significant wave height, U10Nis the horizontal wind speed at 10-m height under the neutral atmospheric condition, andcp is the phase velocity of the peak wave spectrum. The results show (1) u* = 0.024U10N(gHs/U10N2)-1/4, (2) z0 = 10 × exp[-4.797(gHs/u*2)1/6] or z0 = 10 × exp[-16.613(gHs/U10N2)1/4], and (3) CDN = 0.007(gHs/u*2)-1/3 or CDN = 5.76 × 10-4(gHs/U10N2)-1/2. The present parameterization schemes were experimentally tested.

We proposed a new combination skin care for infants which consisted of a foaming cleanser with lower surfactant activity and moisturizers that contained pseudo-ceramide. Subjects and methods: A total of 50 infants (age: 3–24 months with insignificant levels of dry skin were enrolled in this usage trial. The parents washed the infants with the test cleanser while bathing and then applied the moisturizer (lotion or cream containing pseudo-ceramide. Prior to and following the 4-week usage period, visual evaluation of the skin condition was conducted by a dermatologist, in addition to instrumental analysis. Results: Erythema and papule, accompanied by dryness, were commonly observed at week 0. However, by week 4, these symptoms significantly improved; the condition of none of the subjects deteriorated. The number of infants with lower cutaneous barrier function and higher skin pH decreased. The parents of the infants recognized improvements in the skin symptoms and were appreciative of the test materials. Conclusion: The combined usage of the foaming cleanser with lower surfactant activity and a moisturizer containing pseudo-ceramide may be effective in maintaining healthy infant skin and ameliorating the skin symptoms.

Daily cocoa intake has been shown to reduce central arterial stiffness in health adults, regardless of age; however, the effect of cocoa-intake frequency on arterial stiffness in postmenopausal women remains unclear. Therefore, the purpose of this study was to investigate the effects of cocoa-intake frequency on arterial stiffness in postmenopausal women. A total of 26 postmenopausal women (mean age ± standard deviation 64±12 years were randomly assigned to two groups with different cocoa-intake frequencies: one group ingested 17 g of cocoa once daily except on Sundays (every-day group, n=13, and the other ingested 17 g of cocoa twice daily every other day (every-other-day group, n=13. These intake regimens were maintained in both groups for 12 weeks. Carotid–femoral pulse-wave velocity and femoral–ankle pulse-wave velocity were measured in both groups at baseline and again at the end of the 12-week study period. Compared to baseline, both pulse-wave velocities had significantly decreased after the 12-week study period in both groups (P<0.05. However, no significant difference in degree of change was observed between the two groups. Although this study did not include a sedentary control group, these results suggest that regardless of frequency, habitual cocoa intake reduces central and peripheral arterial stiffness in postmenopausal women.

Cyclometalated iridium (III) complexes formed with three identical cyclometalating (C-N) ligands (homoleptic) or formed with two cyclometalating (C-N) ligands and one ancillary (LX) ligand (heteroleptic) have been known as highly phosphorescent materials and, thus, they have been utilized as efficient phosphorescent dopants in organic light emitting diodes (OLEDs) 1–3 or as effective phosphorescent chemosensors. 4–7 Cylometalated iridium (III) complexes are chiral compounds consisting of lambda (Λ, left-handed) and delta (Δ, right-handed) isomers. Racemic cyclometa- lated iridium (III) complexes emit light with no net polarization, but optically active cyclometalated iridium (III) complexes emit circularly polarized light. 8,9 Circularly polarized light can be used in various fields including highly efficient three dimensional electronic devices, photo nic devices for optical data storage, biological assays, and others. 8,9 In order to obtain optically active cylometalated iridium (III) complexes and to determine the enantiomeric composition of optically active cylometalated iridium (III) complexes, liquid chromatogr aphic enantiomer separation method on chiral stationary phases (CSPs) has been used. For example, Okamoto and coworkers first reported the high performance liquid chromatographic (HPLC) direct enantiomeric separation of two homoleptic cylometalated iridium (III) complexes on immobilized amylose tris(3,5- dimethylphenylcarbamate) (Chiralpak IA), coated cellulose tris(3,5-dimethylphenylcarbamate) (Chiralc el OD), and coated cellulose tris(4-methylbenzoate) (Chiralce l OJ). 10 Supercritical fluid chromatography (SFC) was also used by Bernhard and coworkers for the enantiomeric separation of cylometalated iridium (III) complexes on coated amylose tris(3,5-dimethylphenylcarbamate) (Chiralpak AD-H). 8 However, the general use of the HPLC method for the direct enantiomeric separation of homoleptic

It was introduced to Japan in the middle of the sixth century and has evolved over the past 1,400 years after combining with Japan’s original folk remedies. While it retains some similarities to TCM, Kampo has evolved in Japan, resulting in a system of medicine that has many differences from TCM. Kampo medicine is considered to be very safe; in Japan, Kampo herbal formulas are manufactured by licensed pharmaceutical companies, prescribed by Western-trained medical doctors (usually as a freeze-dried extract, and have quality control standards similar to those of prescription drugs. The present study examined Yokukan-san (Yi-Gan San in TCM, a Kampo formula that has been used empirically in Japan for more than 400 years. Accumulating clinical trials have demonstrated Yokukan-san’s efficacy in treating patients with behavioral and psychological symptoms of dementia, which has resulted in the Japanese Society of Neurology listing it in the Japanese Guidelines for the Management of Dementia 2010. Efficacy in other diseases and conditions, such as sleep disorders, tardive dyskinesia, aggression, and impulsivity has also been reported.

For example, Okamoto and coworkers first reported the high performance liquid chromatographic (HPLC) direct enantiomeric separation of two homoleptic cylometalated iridium (III) complexes on immobilized amylose tris(3,5- dimethylphenylcarbamate) (Chiralpak IA), coated cellulose tris(3,5-dimethylphenylcarbamate) (Chiralc el OD), and coated cellulose tris(4-methylbenzoate) (Chiralce l OJ). 10 Supercritical fluid chromatography (SFC) was also used by Bernhard and coworkers for the enantiomeric separation of cylometalated iridium (III) complexes on coated amylose tris(3,5-dimethylphenylcarbamate) (Chiralpak AD-H). 8 However, the general use of the HPLC method for the direct enantiomeric separation of homoleptic.

Understanding the processes of historical land-use change is crucial to the research of global environmental sustainability. Here we examine and attempt to disentangle the evolutionary interactions between land-use change and its underlying causes through a historical lens. We compiled and synthesized historical land-use change and various biophysical, political, socioeconomic, and technical datasets, from the Qing dynasty to modern China. The analysis reveals a clear transition period between the 1950s and the 1980s. Before the 1950s, cropland expanded while forested land diminished, which was also accompanied by increasing population; after the 1980s land-use change exhibited new characteristics: changes in cropland, and decoupling of forest from population as a result of agricultural intensification and globalization. Chinese political policies also played an important and complex role, especially during the 1950s–1980s transition periods. Overall, climate change plays an indirect but fundamental role in the dynamics of land use via a series of various cascading effects such as shrinking agricultural production proceeding to population collapse and outbreaks of war. The expected continuation of agricultural intensification this century should be able to support increasing domestic demand for richer diets, but may not be compatible with long-term environmental sustainability.

However, roles of long noncoding RNAs in osteosarcoma remain unclear. This study is to investigate the clinical relevance and biological functions of long noncoding RNA 91H in osteosarcoma. Herein, we confirmed that 91H expression was notably increased in osteosarcoma patients and cell lines compared to healthy controls and normal human bone cell lines. High expression of 91H was significantly correlated with advanced clinical stage, chemotherapy after surgery, and tumor size >5 cm. Furthermore, 91H was an independent prognostic factor for overall survival in osteosarcoma patients after treatments. Additionally, the knockdown of 91H expression inhibited osteosarcoma cells’ proliferation and promoted their apoptosis in vitro. In summary, these findings indicate that 91H may be a novel biomarker for risk prognostication and also provide a clue to the molecular etiology of osteosarcoma. Keywords: long noncoding RNA, 91H, osteosarcoma, survival

2014-01-01

Background This study interviewed community pharmacists in Shanghai and Guangzhou for their perception of the popular categories of over-the-counter (OTC) Chinese medicines and the factors affecting customer preferences for OTC Chinese medicines. Methods A cross-sectional survey was carried out in six main administrative districts in Guangzhou and eight main administrative districts in Shanghai, China. Descriptive statistical analysis was conducted in this study. Results OTC Chinese medicines contributed 21–50% among all the pharmaceutical sales by the community pharmacies. The prevalent categories of OTC Chinese medicines were common cold medicines, respiratory system medicines, digestive system agents, gynecological medicines, health tonic medicines, and qing re (heat-clearing) and qu du (detoxifying) medicines. Customers were more concerned about medical factors of OTC Chinese medicines than business factors. Among the medical factors, the most important was drug safety, followed by efficacy, contraindications, indications, and side effects. Among the business factors, the most important were brand and price. Conclusions This study identified the top sales categories of OTC Chinese medicines in Shanghai and Guangzhou and the important factors such as drug safety, efficacy, period of validity, contraindications, and indications that are affecting the customer preferences for OTC Chinese medicines.

Full Text Available Objectives. To apply modern text-mining methods to identify candidate herbs and formulae for the treatment of diabetic nephropathy. Methods. The method we developed includes three steps: (1 identification of candidate ancient terms; (2 systemic search and assessment of medical records written in classical Chinese; (3 preliminary evaluation of the effect and safety of candidates. Results. Ancient terms Xia Xiao, Shen Xiao, and Xiao Shen were determined as the most likely to correspond with diabetic nephropathy and used in text mining. A total of 80 Chinese formulae for treating conditions congruent with diabetic nephropathy recorded in medical books from Tang Dynasty to Qing Dynasty were collected. Sao si tang (also called Reeling Silk Decoction was chosen to show the process of preliminary evaluation of the candidates. It had promising potential for development as new agent for the treatment of diabetic nephropathy. However, further investigations about the safety to patients with renal insufficiency are still needed. Conclusions. The methods developed in this study offer a targeted approach to identifying traditional herbs and/or formulae as candidates for further investigation in the search for new drugs for modern disease. However, more effort is still required to improve our techniques, especially with regard to compound formulae.

Carbon nanotubes (CNTs and silk fibroin (SF were used to modify the surface of the nHA/PA66 scaffolds by freeze-drying and cross-linking. Dexamethasone was absorbed to the CNTs to promote the osteogenic differentiation of bone mesenchymal stem cells (BMSCs. The cell viability of BMSCs was investigated by changing the concentration of the CNT dispersion, and the most biocompatible scaffold was selected. In addition, the morphology and mechanical property of the scaffolds were investigated. The results showed that the nHA/PA66 scaffolds modified with CNTs and SF met the requirements of bone tissue engineering scaffolds. The dexamethasone-loaded CNT/SF-nHA/PA66 composite scaffold promoted the osteogenic differentiation of BMSCs, and the drug-loaded scaffolds are expected to function as effective bone tissue engineering scaffolds.

Full Text Available The Leizhou Peninsula in western Guangdong (concurrent with the present-day municipality of Zhanjiang has at several points in history been an important site of exchange, both licit and illicit in the eyes of central authorities. The French gained control of the area from the weakened Qing government in 1898–1899 and established their “leased territory” of Guangzhouwan. Administered as part of French Indochina, Guangzhouwan became a fiefdom of smugglers, pimps, and pirates, never developing into the rival to Hong Kong that the French hoped it would become. After a brief Japanese occupation, the French returned the leased territory to the government of Chiang Kai-shek (Jiang Jieshi after World War II, but their colonial presence left a legacy of trafficking, violence, and anti-imperialism that emboldened Communist guerrillas in the area. Once the Communists came into power in 1949, they subjected Zhanjiang and other liminal spaces along the Chinese coast to vigorous anti-smuggling and anti-drug campaigns. But a return to smuggling in the Reform Era (1978–present suggests that the successful repression of smuggling in the Mao era may have been a temporary exception to the historical rule in this region.

Interlopers, Rogues, or Cosmopolitans? Wu Jianzhang and Early Modern Commercial Networks on the China Coast

Directory of Open Access Journals (Sweden)

Peter C. Perdue

2017-12-01

Full Text Available After the First Opium War (1839–1842, British and American merchants negotiated with Chinese officials in Shanghai to work out the framework of the new treaty port regime. One key player in these negotiations was Wu Jianzhang, a Cantonese merchant who became circuit intendant of the Shanghai region. Wu, however, also had links to Cantonese sailors and anti-Qing secret societies. When the Small Swords Society took Shanghai in 1853, he found himself entangled in conflicting responsibilities and networks. Foreign traders and Chinese officials regarded Wu, like other middlemen on the Chinese coast, with a mixture of respect and distrust. Wu’s situation, however, was not unique to the mid-nineteenth century. This article compares Wu to other intermediaries who played similar roles in the sixteenth and late nineteenth centuries, in order to show the ways in which Wu, his predecessors, and those who followed in his footsteps connected China to the wider world by navigating the treacherous waters of diplomacy, war, and commerce. The work of John K. Fairbank, who in the 1950s pioneered the study of such people as Wu Jianzhang, can find new meaning in the twenty-first century, enabling us to understand the transnational implications of China’s local social history.

Among the main sites of production of ancient Chinese blue and white porcelains can be included Jingdezhen in Jiangxi Province, the Yuxi and Jianshui Kilns of Yunnan Province and the Pinghe Kiln of Fujian Province. The current work focuses on an elemental characterization of ancient porcelains according to the location of manufacture, also incorporating a similar study of the blue and white porcelains of the Qing dynasty from Wun Yiu in Hong Kong, and modern blue and white porcelains from Germany, Japan and Thailand. Non-destructive analysis of samples of porcelain using energy dispersive X-ray fluorescence (EDXRF) has yielded results in terms of 13 chemical elements, namely, Ti, Mn, Fe, Co, Ni, Cu, Zn, Ga, Pb, Rb, Sr, Y and Zr. Principal component analysis has been performed on the data, allowing representation of the first, second and third principal components of the data in 3 D scatter plots; the results reveal data clusterings which correlate to a high degree with the known sites of origin. The conclusion is that the present method is capable of determining differences in elemental concentrations of blue and white porcelains, and that these differences can be used to locate the originating site of manufacture.

The influence of a polyethylene glycol (PEG coating on the distribution and toxicity of the NGO was also investigated. The results show that NGO is mainly retained in the liver, lung, and spleen. Retention in the lung is partially due to NGO aggregation. The PEG coating reduces the retention of NGO in the liver, lung, and spleen and promotes the clearance of NGO from these organs, but NGO and NGO-PEG are still present after 3 months. The PEG coating effectively reduces the early weight loss caused by NGO and alleviates NGO-induced acute tissue injuries, which can include damage to the liver, lung, and kidney, and chronic hepatic and lung fibrosis.

By investigating the mainstream works of herbal classics of successive ages, it is found that adulteration of Chinese materia medica appeared early in ancient China. The main methods of adulteration was producing fraud medicines in the Northern-Southern Dynasties, fake medicines began to appear in the Tang Dynasty, and status of adulteration of Chinese materia medica ran unchecked since the Ming and Qing Dynasty. By statistics, there were 76 kinds of adulteration varieties before the Republican period. The main varieties were precious drugs, animal drugs and artifacts. Commonly methods used in the process included forging and adulterating, dealing with 11 kinds and 68 kinds respectively. Adulteration probably lead to the result of imposing the changes of the used medicinal parts of Herba Pogostemonis; Radix Aconiti Lateralis prepared by adding salt, Radix Angelica Sinensis processed by wine, and Radix Astragalis seu Hedysaris processed with bee honey. However, the root cause of adulteration in Chinese materia medica was the dissociation of professional physician and pharmacist, resulting in the ignorance of medical practitioners became unable to recognize Chinese materia medica; and the immorality of medicinal merchants. Besides, rating the quality of materia medica based on its producing areas without differentiating the false from the genuine may also contribute to this result passively.

The emergency treatments for the damage and bleeding of the vagina, and the sharp pubic pain of young virgins which were caused occurred by the sexual art, were recorded in traditional medicine books, such as the "Ji yan fang" and others. It is a fact that in ancient China some people used the sexual art of having intercourse with several young virgins at the same time in order to increase their health and keep perpetual youth and longevity. The famous traditional general-medical book, "qian jin yao fang" recommended that method to rich persons too. It is supposed that the beginning of the sexual art of having intercourse with several young virgins traces back to the times of Emperor Hanwu , but it seems to have disappeared from the historical stage in the Song period. On the other hand, the criticisms from the traditional medicine books and the secret languages of internal alchemy used for the Taoist sacred books show that the sexual art of having intercourse with several young virgins was still going on behind the scene in the Ming and Qing periods. Even if we consider the historical changes of ethics and mortality, we now cannot but criticize this behavior of abusing juveniles for the sexual art.

Yeh, Hui-Yuan; Mitchell, Piers D

2016-10-01

Whilst archaeological evidence for many aspects of life in ancient China is well studied, there has been much less interest in ancient infectious diseases, such as intestinal parasites in past Chinese populations. Here, we bring together evidence from mummies, ancient latrines, and pelvic soil from burials, dating from the Neolithic Period to the Qing Dynasty, in order to better understand the health of the past inhabitants of China and the diseases endemic in the region. Seven species of intestinal parasite have been identified, namely roundworm, whipworm, Chinese liver fluke, oriental schistosome, pinworm, Taenia sp. tapeworm, and the intestinal fluke Fasciolopsis buski . It was found that in the past, roundworm, whipworm, and Chinese liver fluke appear to have been much more common than the other species. While roundworm and whipworm remained common into the late 20th century, Chinese liver fluke seems to have undergone a marked decline in its prevalence over time. The iconic transport route known as the Silk Road has been shown to have acted as a vector for the transmission of ancient diseases, highlighted by the discovery of Chinese liver fluke in a 2,000 year-old relay station in northwest China, 1,500 km outside its endemic range.

It is very difficult to measure the chemical composition of colored pigments of over-glaze porcelain by X-ray fluorescence because it contains high concentration of Pb. One of the disadvantages of our polycapillary optics is that it has low transmission efficiency to the high energy X-ray. However, it is beneficial to measure the chemical compositions of rich Pb sample. In this paper, we reported the performances of a tabletop setup of micro-X-ray fluorescence system base on slightly focusing polycapillary and its applications for analysis of rich Pb sample. A piece of Chinese ancient over-glaze porcelain was analyzed by micro-X-ray fluorescence. The experimental results showed that the Cu, Fe and Mn are the major color elements. The possibilities of the process of decorative technology were discussed in this paper, also.

As a first step the network of power, as reflected in the so-called medical palace memorials, will be presented in order to arrive at a more comprehensive evaluation of the medical involvement of the Jesuits, as practising physicians, suppliers of foreign drugs and as patients. It will be shown that the circumstances of Thomas’ illness and death must be based on a political and social analysis of the role of court medicine as patronised by the Kangxi emperor. Secondly, the case study of Antoine Thomas will also allow us to reflect on the delocalisation and appropriation of theriac at the Chinese court - one of the foreign drugs in the supply of which Jesuits might have been participated. Last but not least, I shall introduce a number of references in archival documents which throw some additional light on Thomas’ illness and death, and how they were perceived and dealt with in the imperial court.

The lack of age-pigments and the alterations in intracellular monovalent electrolytes in spontaneously hypertensive, stroke-prone (SHRsp) rats as revealed by electron microscopy and X-ray microanalysis

Nagy, I.; Nagy, V.; Casoli, T.; Lustyik, G.

1989-01-01

Male, spontaneously hypertensive, stroke-prone (SHRsp) rats established by Okamoto et al. were studied. About 80% of the males of this strain have a particularly short life span (33-41 weeks); they display a considerable hypertension (above 220 mmHg) and a tendency for plurifocal brain strokes. Hypertension and strokes can be provoked in an accelerated and synchronized fashion by supplementing 1% NaCl into their drinking water. Symptoms of the appearance of brain strokes can be judged from characteristic signs of motor disorders, and can be established also by pathohistology. Since hypertension and arteriosclerosis are frequently involved in aging, the question we intended to answer was whether these animals may represent a model of the normal aging process or not. Two approaches are described: (1) Accumulation of lipofuscin granules in their brain, liver and myocardium was followed by transmission electron microscopy before and after the appearance of strokes. It has been established that these tissues do not show any typical accumulation of lipofuscin granules, although submicroscopic signs of an enhanced damage of cell organelles (especially of mitochondria in liver and brain cells, but not in myocardium) were encountered. (2) The intracellular monovalent composition in the brain and liver was measured by using bulk-specimen X-ray microanalysis. The intracellular Na-content (mEq/kg water) was significantly higher (170-200%) in both the brain and liver cells, whereas the K-content increased only moderately (118-130%). The results suggest that although the SHRsp rats do not represent a direct model for the normal aging process from the point of view of lipofuscin accumulation, the shifts of the monovalent electrolyte contents in the brain and liver cells observed already in the youngest ages, are similar to those observed in aged normal rats

Rhizoctonia solani causes rice sheath blight, an important disease affecting the growth of rice (Oryza sativa L.). Attempts to control the disease have met with little success. Based on transcriptional profiling, we previously identified more than 11,947 common differentially expressed genes (TPM > 10) between the rice genotypes TeQing and Lemont. In the current study, we extended these findings by focusing on an analysis of gene co-expression in response to R. solani AG1 IA and identified gene modules within the networks through weighted gene co-expression network analysis (WGCNA). We compared the different genes assigned to each module and the biological interpretations of gene co-expression networks at early and later modules in the two rice genotypes to reveal differential responses to AG1 IA. Our results show that different changes occurred in the two rice genotypes and that the modules in the two groups contain a number of candidate genes possibly involved in pathogenesis, such as the VQ protein. Furthermore, these gene co-expression networks provide comprehensive transcriptional information regarding gene expression in rice in response to AG1 IA. The co-expression networks derived from our data offer ideas for follow-up experimentation that will help advance our understanding of the translational regulation of rice gene expression changes in response to AG1 IA.

The karst region of Southwest China with an area of 54 × 104 km2 is one of the largest karst areas in the world and experiences subtropical climate. Hill-depressions are common landforms in the mountain areas of this region. Downslope soil movement on the ground by surface water erosion and soil sinking into underground holes by creeping or pipe erosion are mayor types of soil movements on rocky carbonate slopes. The 137Cs technique was used to date the sediment deposits in six karst depressions, to estimate average surface erosion rates on slopes from their catchments. The estimates of soil loss rates obtained from this study evidenced considerable variability. A value of 1.0 t km-2 year-1 was obtained for a catchment under original dense karst forest, but the erosion rates ranged between 19.3 t km-2 year-1 and 48.7 t km-2 year-1 in four catchments under secondary forest or grasses, where the original forest cover had been removed in the Ming and Qing dynasties, several hundred years ago. The highest rate of 1643 t km-2 year-1 was obtained for a catchment underlain by clayey carbonate rocks, where the soil cover was thicker and more extensive than in the other catchments and extensive land reclamation for cultivation had occurred during the period 1979-1981, immediately after the Cultural Revolution.

Fuzi is a medicine used for rescuing from collapse by restoring yang as well as a famous toxic traditional Chinese medicine. In order to ensure the efficacy and safe medication, Fuzi has mostly been applied after being processed. There have been different Fuzi processing methods recorded by doctors of previous generations. Besides, there have also been differences in Fuzi processing methods recorded in modern pharmacopeia and ancient medical books. In this study, the authors traced back to medical books between the Han Dynasty and the period of Republic of China, and summarized Fuzi processing methods collected in ancient and modern literatures. According to the results, Fuzi processing methods and using methods have changed along with the evolution of dynasties, with differences in ancient and modern processing methods. Before the Tang Dynasty, Fuzi had been mostly processed and soaked. From Tang to Ming Dynasties, Fuzi had been mostly processed, soaked and stir-fried. During the Qing Dynasty, Fuzi had been mostly soaked and boiled. In the modem times, Fuzi is mostly processed by being boiled and soaked. Before the Tang Dynasty, a whole piece of Fuzi herbs or their fragments had been applied in medicines; Whereas their fragments are primarily used in the modern times. Because different processing methods have great impacts on the toxicity of Fuzi, it is suggested to study Fuzi processing methods.

Pharmaceutically active compounds (PhACs) as an important group of "emerging contaminants" (ECs), have been highlighted and received global attentions in last decade. China has tremendous consumption of PhACs and the most pharmaceutical manufacturers worldwide. In this study, 33 PhACs (19 antibiotics included) were monitored in the Beiyun River basin in Beijing, China. The seasonal occurrence, temporal-spatial distribution and potential source were investigated. The total levels were about 2μgL -1 . Non-antibiotics were more frequently detected. The highest median concentrations were observed for caffeine (558ngL -1 ) and erythromycin (319ngL -1 ). Acetaminophen, erythromycin, diclofenac and N,N-diethyl-meta-toluamide showed highly significant seasonal variation, while caffeine, carbamazepine, metoprolol and most sulfonamides were more stable. The burden was most heavy in Qing River in both seasons (up to 4μgL -1 ). Antibiotics from veterinary use accounted for minor contribution in this region. The characteristics and trends were overviewed by comparing with our previous survey. The total level of 15 PhACs dropped significantly by 37% on average from 2013 to 2015. The proportion of caffeine, once a major component in 2013, reduced from 77% to 47%. The burden of these ECs in surface water of Beijing is remarkably reduced, suggesting the overall situation has been improving. Copyright © 2016 Elsevier B.V. All rights reserved.

The historical and cultural heritage of Qingxing palace and Lingyin and Kaihua temple, located in Hangzhou of China, include a large number of exquisite Buddhist statues and ancient stone sculptures which date back to the Northern Song (960-1219 A.D.) and Qing dynasties (1636-1912 A.D.) and are considered to be some of the best examples of ancient stone sculpting techniques. They were added to the World Heritage List in 2011 because of their unique craftsmanship and importance to the study of ancient Chinese Buddhist culture. However, biodeterioration of the surface of the ancient Buddhist statues and white marble pillars not only severely impairs their aesthetic value but also alters their material structure and thermo-hygric properties. In this study, high-throughput sequencing was utilized to identify the microbial communities colonizing the stone monuments. The diversity and distribution of the microbial communities in six samples collected from three different environmental conditions with signs of deterioration were analyzed by means of bioinformatics software and diversity indices. In addition, the impact of environmental factors, including temperature, light intensity, air humidity, and the concentration of NO2 and SO2, on the microbial communities' diversity and distribution was evaluated. The results indicate that the presence of predominantly phototrophic microorganisms was correlated with light and humidity, while nitrifying bacteria and Thiobacillus were associated with NO2 and SO2 from air pollution.

Full Text Available Michael Gibbs Hill's excellent translation of the introduction to Wang Hui's four-volume opus, The Rise of Modern Chinese Thought 现代中 国思想的兴起 provides a substantial contribution to scholars of China and intellectual historians by bringing another of Wang Hui's critical works into English (for other such examples, see Wang and Huters 2003 and 2011. The task of translating could not have been easy, as Wang Hui frequently cites works from Chinese antiquity and translated texts from abroad, making Hill's results truly exceptional. The translation is accessible and painstakingly executed, with many important phrases explained for non-specialists alongside transliterated key terms. The Rise of Modern Chinese Thought demonstrates the need for translation work in the fields of area studies by making the important works of non-English speakers available to Anglophone audiences. As Zhang Yongle pointed out in his review on the work in toto, "It can safely be said that nothing comparable to Wang Hui's work has appeared in China since the late Qing-early Republican period" (Zhang 2010:71. Wang Hui, while exploring the links between China and its past through the country's rich intellectual traditions, manages to deftly discuss China in global terms and historical contexts. Hill's helpful introduction contextualizes Wang's writing style in the zeitgeist of the post Tiananmen period from 1990 to 2010. ...

Full Text Available Cloud computing has attracted more and more attention as it reduces the cost of IT infrastructure of organizations. In our country, business Cloud services, such as Alibaba Cloud, Huawei Cloud, QingCloud, UCloud and so on are gaining more and more uses, especially small or median organizations. In the cloud service scenario, the program and data are migrating into cloud, resulting the lack of trust between customers and cloud service providers. However, the recent study on Cloud computing is mainly focused on the service side, while the data security and trust have not been sufficiently studied yet. This paper investigates into the data security issues from data life cycle which includes five steps when an organization uses Cloud computing. A data management framework is given out, including not only the data classification but also the risk management framework. Concretely, the data is divided into two varieties, business and personal information. And then, four classification levels (high, medium, low, normal according to the different extent of the potential adverse effect is introduced. With the help of classification, the administrators can identify the application or data to implement corresponding security controls. At last, the administrators conduct the risk assessment to alleviate the risk of data security. The trust between customers and cloud service providers will be strengthen through this way.

Social Darwinism in modern China

XU Jilin; XIAO Zhiwei

2012-01-01

After evolutionary theory was introduced in China,Herbert Spencer's interpretation of it in the form of social Darwinism persuaded the Chinese that if they wanted to strengthen their nation,they would have to accept the brutal truth of natural selection,in which the principle of survival of the fittest rules.This version of evolutionary theory,when combined with the pragmatic thrust of Confucianism and the realpolitik of legalism from China's indigenous tradition,started a storm of materialism and utilitarianism in modern China.In the process,the traditional social order based on the rule of propriety (li) was completely subverted and replaced by a new order predicated on the rule of competition and power.This development produced a new mental outlook that privileged power over everything else,seriously undermined the rules of ethics and caused serious political consequences in the late Qing and early Republican period.This intellectual development may have contributed to ending the dynastic rule in China,but it was also responsible for ruining the newborn Republican China.The Chinese intellectuals of the May Fourth era critically reflected on this problematic legacy.While still believing in the notion of progress,they abandoned social Darwinism and embraced the idea of evolution through mutual assistance.Thus began a historical shift in modern China from focusing on wealth and power to focusing on civilization as China's salvation.

This study examined these two factors in the brains of rats following unpredictable chronic mild stress for 4 weeks, with the hypothesis that chronic stress may affect oligodendrocytes and elevate proinflammatory cytokines in the brain. After suffering unpredictable stressors for 4 weeks, the rats showed depression-like behaviors, including decreased locomotion in the open field, increased immobility time in the forced swim test, and decreased sucrose consumption and less sucrose preference when compared with controls. Immunohistochemical staining of brain sections showed higher immunoreactivity of proinflammatory cytokines in certain brain regions of stressed rats compared with controls; lower immunoreactivity of myelin basic protein and fewer mature oligodendrocytes were seen in the prefrontal cortex, but no demyelination was detected. These results are interpreted and discussed in the context of recent findings from human and animal studies. Keywords: cytokines, depression, myelination, oligodendrocytes, stress

However, most studies have focused on the efficacy of TKI, and few studies have been done on the criteria for their discontinuation. The current standard for drug discontinuation is “until progression”, based on change in tumor size. However, tumor size is not related to the gene expression which determines the efficacy of TKI in the final analysis, and it is also difficult to make a thorough and correct prediction based on tumor size when the TKI is discontinued. Nevertheless, clinical evaluation of the criteria for TKI discontinuation is still in its early days. Some promising findings have started to emerge. With the improving knowledge of EGFR and its inhibitors, it is expected that the criteria for discontinuation of EGFR inhibitor therapy will become clearer.Keywords: epidermal growth factor receptor, drug discontinuation, acquired drug-resistance

To clarify the change and development of the original plants， medicinal organs， traditional functions， resource distribution of "Huangjing"(Polygonati Rhizome)， a traditional Chinese medicine， we investigated Polygonatum species on the ancient Chinese herbal texts. The name of "Nüwei" was first carried out in the book of Sheng Nong's Herbal Classic. Its effects included two aspects： one was similar to "Weirui"(Polygonati Odorati Rhizome， "Yuzhu")， that was tonifying， nourishing one's vitality， removing wind and dampness， settling five organs， making body lightness， keeping longevity and not being hungry; the second was alike to "Huangjing" recorded in the book of Ming Yi Bie Lu(Appendant Records of Famous Physicians). Specifically， "Weirui" possesses the therapeutic effect of "Nüwei"， while "Huangjing" possesses the tonic effect of " Nüwei". Thereafter， the following ancient Chinese herbal texts kept those two names and function records. Accordingly， we hold the point of view that "Huangjing" was first carried out in the book of Sheng Nong's Herbal Classic in the synonym of "Nüwei". "Yuzhu" included the "Huangjing" in ancient herbal text before Qing Dynasty， that was further confirmed by the research on change and development of the original plants. The identification between "Yuzhu" and "Huangjing" was based on the shape of rhizome and size before early Tang Dynasty. The shape was a key character and used up to now， but size was not reasonable. The opposite phyllotaxy was an important character of authentic "Huangjing" from Tang to Qing Dynasty. The seedling of Polygonatum sibiricum and P. kingianum， the adult plant of P. cyrtonema with alternate leaves were misused as "Yuzhu"("Nüwei" and "Weirui") at that time. Therefore， both "Yuzhu" and "Huangjing" should be used as key words during the search of ancient prescriptions and development of new drugs and health foods. The leaves， flowers， fruits and seedlings could

We report on research into building a cyberinfrastructure for Chinese biographical and geographic data. Our cyberinfrastructure contains (i) the McGill-Harvard-Yenching Library Ming Qing Women's Writings database (MQWW), the only online database on historical Chinese women's writings, (ii) the China Biographical Database, the authority for Chinese historical people, and (iii) the China Historical Geographical Information System, one of the first historical geographic information systems. Key to this integration is that linked databases retain separate identities as bases of knowledge, while they possess sufficient semantic interoperability to allow for multidatabase concepts and to support cross-database queries on an ad hoc basis. Computational ontologies create underlying semantics for database access. This paper focuses on the spatial component in a humanities cyberinfrastructure, which includes issues of conflicting data, heterogeneous data models, disambiguation, and geographic scale. First, we describe the methodology for integrating the databases. Then we detail the system architecture, which includes a tier of ontologies and schema. We describe the user interface and applications that allow for cross-database queries. For instance, users should be able to analyze the data, examine hypotheses on spatial and temporal relationships, and generate historical maps with datasets from MQWW for research, teaching, and publication on Chinese women writers, their familial relations, publishing venues, and the literary and social communities. Last, we discuss the social side of cyberinfrastructure development, as people are considered to be as critical as the technical components for its success. PMID:21444819

The autolysis of brewer's yeast during beer production has a significant effect on the quality of the final product. In this work, we performed proteome and transcriptome studies on brewer's yeast to examine changes in protein and mRNA levels in the process of autolysis. Protein and RNA samples of the strain Qing2 at two different autolysis stages were obtained for further study. In all, 49 kinds of proteins were considered to be involved in the autolysis response, eight of which were up-regulated and 41 down-regulated. Seven new kinds of proteins emerged during autolysis. Results of comparative analyses showed that important changes had taken place as an adaptive response to autolysis. Functional analysis showed that carbohydrate and energy metabolism, cellular amino acid metabolic processes, cell response to various stresses (such as oxidative stress, salt stress, and osmotic stress), translation and transcription were repressed by the down-regulation of the corresponding proteins, and starvation and DNA damage responses could be induced. The comparison of data on transcriptomes with proteomes demonstrated that most autolysis-response proteins as well as new proteins showed a general correlation between mRNA and protein levels. Thus these proteins were thought to be transcriptionally regulated. These findings provide important information about how brewer's yeast acts to cope with autolysis at molecular levels, which might enhance global understanding of the autolysis process. © 2014 Federation of European Microbiological Societies.

The new nanoparticles (called A-PTX-SF-NPs were prepared using the carbodiimide-mediated coupling procedure and their characteristics were evaluated. The cellular cytotoxicity and cellular uptake of A-PTX-SF-NPs were also investigated. The results in vivo suggested that NPs conjugated with the recombinant protein exhibited more targeting and anti-neoplastic property in cells with high EGFR expression. In the in vivo antitumor efficacy assay, the A-PTX-SF-NPs group showed slower tumor growth and smaller tumor volumes than PTX-SF-NPs in a HeLa xenograft mouse model. A real-time near-infrared fluorescence imaging study showed that A-PTX-SF-NPs could target the tumor more effectively. These results suggest that the anticancer activity and tumor targeting of A-PTX-SF-NPs were superior to those of PTX-SF-NPs and may have the potential to be used for targeted delivery for tumor therapies.

Many species of the genus Ephedra plants are used as Chinese traditional medicines, in Chinese which are known as "Mahuang" (Ephedrae Herba). In order to get a clear picture of resources distribution and varieties on Chinese markets of the crude drug Mahuang and provide scientific basis for their resource conservation and sustainable use, during recent years we conducted field investigations and market researches many times. The results showed that the most common species on the Chinese markets was E. sinica (33/38 commercial samples), followed by E. intermedia (5/38 commercial samples), which was also used in local clinics in Qing-hai, Gansu and Xinjiang province, no E. equisetina was found in the market. We noticed that the resources of both official and non-official plants of Mahuang, especially Zhong-Mahuang and Muzei-Mahuang, were seriously damaged in the past decade because of the ecological environment damage and over-digging. Zhong-Mahuang was distinguished in Ningxia and north Gansu, which was once one of the most distribution areas and contains more than 10,000 t Zhong-Mahuang. Muzei-Mahuang was distinguished in most places and distributed sparsely around Altay Mountains in northeast in Xinjiang. Thus, Cultivation of Mahuang, especially Zhong-Mahuang and Muzei-Mahuang should be greatly developed. At the same time, wild resources of Mahuang must be preserved strictly, i.e., proper method of cutting Ephedra plant could prevent the damage of the resource.

Mostly, pedestrian car accidents occurred at a signalized interaction is because pedestrians cannot across the intersection safely within the green light. From the viewpoint of pedestrian, there might have two reasons. The first one is pedestrians cannot speed up to across the intersection, such as the elders. The other reason is pedestrians do not sense that the signal phase is going to change and their right-of-way is going to be lost. Developing signal logic to protect pedestrian, who is crossing an intersection is the first purpose of this study. In addition, to improve the reliability and reduce delay of public transportation service is the second purpose. Therefore, bus preemption is also considered in the designed signal logic. In this study, the traffic data of the intersection of Chong-Qing North Road and Min-Zu West Road, Taipei, Taiwan, is employed to calibrate and validate the signal logic by simulation. VISSIM 5.20, which is a microscopic traffic simulation software, is employed to simulate the signal logic. From the simulated results, the signal logic presented in this study can protect pedestrians crossing the intersection successfully. The design of bus preemption can reduce the average delay. However, the pedestrian safety and bus preemption signal will influence the average delay of cars largely. Thus, whether applying the pedestrian safety and bus preemption signal logic to an intersection or not should be evaluated carefully

However, the pedestrian safety and bus preemption signal will influence the average delay of cars largely. Thus, whether applying the pedestrian safety and bus preemption signal logic to an intersection or not should be evaluated carefully.

The Body and Military Masculinity in Late Qing and Early Republican China: The Art of Governing Soldiers. New York: Lexington Books, 2016. Historians D. Colin Jaundrill and Nicolas Schillinger have given us two books full of excellent reasons for historians to take the militarism of modernity most seriously. Despite the similarities across modernizing nation-states, as well as of notions of the modern man across national boundaries—on the surface at least—Jaundrill and Schillinger have two rather different puzzles to solve. In Japan, the modern soldier emerged from a long-standing warrior tradition. In China, the modern military emerged from the previous social and cultural neglect of the military; it was instead shaped to overcome the “sick man of East Asia” (dongya bingfu notion that was omnipresent around the turn of the twentieth century.... These scholars have turned the next corner of the historical analysis of military establishments in modern East Asia. They apply different critical methodologies to show the enormity of resources that have been invested in establishing and maintaining the military. They show how militaries as institutions shape and transform societies and how they have aggressively—and sometimes subtly—shaped and reshaped social processes and identities.

Driven by the growing numbers of intensified pig farms around cities in China, there are problems of nutrient surplus and shortage of arable land for utilising the manure. Hence, sustainable livestock systems with effective manure management are needed. The objective of this study is to compare the existing manure treatment of a typical pig farm in Beijing area (separate collection of faeces; 'Gan qing fen' system) with an alternative system and to identify the nutrients flow of the whole farm in order to quantify environmental burdens and to estimate the arable land required for sustainable nutrients recycling. Life cycle assessment is used for this purpose. Acidification potential (AP), eutrophication potential (EP) and global warming potential (GWP) are analysed in detail; the functional unit is the annual production of the pig farm. The results show that the cropland area demand for sustainable land application of the effluent can be reduced from 238 to 139 ha with the alternative system. It is possible to transfer 29% of total nitrogen, 87% of phosphorus, 34% of potassium and 75% of magnesium to the compost, and to reduce the total AP, EP and GWP of manure management on the farm by 64.1%, 96.7% and 22%, respectively, compared with the current system. Besides an effective manure management system, a full inventory of the regional nutrients flow is needed for sustainable development of livestock systems around big cities in China.

It has a long history of the fragrance activities in the ancient China. During the period of pre-Qin, it was mainly used in the therapy and worship. Until the Three Kingdoms, the crowd using the fragrance expanded from the royal to the literati and the general officials. People applied the spices to incense clothes, purify rooms, prevent and treat epidemic diseases in daily. In the worship, the spices were dedicated to Gods and other fairies. The fragrance was developed quickly during the period from Wei Dynasty to South and North Dynasties. People had more experiences of spices used as medicines, the formula of spices were used more widely. Then, during the period from Sui Dynasty to Song Dynasty, the fragrance activities climbed to the peak. The fragrance activities were institutionalized, when nobility matched their spices each other. The Literati made spice products and enjoyed the fragrance activities. Doctors knew more than before in the application experiences and species of spices. In the times of Yuan, Ming and Qing Dynasty, the fragrance activities spread among the public. The spices appeared in each side of the daily life of nobility, when natural fruits appeared in the fragrance activities. External therapy with spices appeared in the clinical. In addition to prevention and therapy, spices should be used in the embalming. After a long period, the fragrance activities had gradually developed into a kind of culture.

After three years of upgrading work, PLS-II (S. Shin, Commissioning of the PLS-II, JINST, January 2013) is now successfully operating. The top-up operation of the 3 GeV linear accelerator had to be delayed because of some challenges encountered, and PLS-II was run in decay mode at the beginning in March 2012. The main difficulties encountered in the top-up operation of PLS-II are different levels between the linear accelerator and the storage ring, the 14 narrow gap in-vacuum undulators in operation, and the full energy injection by 3 GeV linear accelerator. Large vertical emittance and energy jitter of the linac were the major obstacles that called for careful control of injected beam to reduce beam loss in the storage ring during injection. The following measures were taken to resolve these problems: (1) The high resolution Libera BPM (see http://www.i-tech.si ) was implemented to measure the beam trajectory and energy. (2) Three slit systems were installed to filter the beam edge. (3) De-Qing circuit was applied to the modulator system to improve the energy stability of injected beam. As a result, the radiation by beam loss during injection is reduced drastically, and the top-up mode has been successfully operating since 19th March 2013. In this paper, we describe the experimental results of the PLS-II top-up operation and the improvement plan.

Precipitation cycles in the middle and lower reaches of the Yellow River (1736-2000)%1736-2000年黄河中下游地区降水变化的周期分析

Based on the long-term precipitation series with annual time resolution in the middle and lower reaches of the Yellow River and its four sub-regions during 1736-2000 reconstructed from the rainfall and snowfall archives of the Qing Dynasty, the precipitation cycles are analyzed by wavelet analysis and the possible climate forcings, which drive the precipitation changes, are explored. The results show that: the precipitation in the middle and lower reaches of the Yellow River has inter-annual and inter-decadal oscillations like 2-4a,quasi-22a and 70-80a. The 2-4a cycle is linked with EI Ni(n)o events, and the precipitation is lower than normal year in the occurrence of the EI Ni(n)o year or the next year; for the quasi-22a and the 70-80a cycles, Wolf Sun Spot Numbers and Pacific Decadal Oscillation (PDO) coincide with the two cycle signals. However, on a 70-80a time scale, the coincidence between solar activity and precipitation is identified before 1830, and strong (weak) solar activity is generally correlated to the dry (wet) periods; after 1830, the solar activity changes to 80-100a quasi-century long oscillation, and the adjusting action to the precipitation is becoming weaker and weaker; the coincidence between PDO and precipitation is shown in the whole time series. Moreover, in recent 100 years, PDO is becoming a pace-maker of the precipitation on the 70-80a time scale.

The precipitation at 17 stations over the middle and lower reaches of the Yellow River is reconstructed during the period of 1736―1910, using the snow and rainfall records in the Qing Dynasty, together with the instrumental observation data of precipitation and farmland soil moisture content. The soil physics model related to rainfall infiltration and the surface water balance equation are taken as main reconstruction methodology. The field infiltration experiment by artificial rainfall is conducted to check the reliability. And the precipitation series over the middle and lower reaches of the Yellow River and its 4 sub-regions are established, going back to 1736. Analysis of the time series indicates that the abrupt change of precipitation from high to low occurs around 1915 over the middle and lower reaches of the Yellow River. During the three periods of 1791―1805, 1816―1830 and 1886―1895, the precipitation is markedly higher than the mean of the series. While both the periods of 1916―1945 and 1981―2000 are characterized by less precipitation. Three periodicities of 22―25a, 3.9a and 2.7a are shown in the precipitation fluctuation over the middle and lower reaches of the Yellow River. Moreover, the periodical signal of 22―25a becomes weaker and weaker since the abrupt change of 1915 and disappears in the late 1940s, and then the periodical signal of 35―40a appears instead.

According to archaeological discoveries, humans began to make use of marine natural resources early in the Palaeolithic era. In the Spring and Autumn period and Warring States period, they began to use marine life as medicines and also had simple cognitions on their efficacy and processing. In the Qin and Han dynasties, people further deepened the understanding of the marine Chinese materia medica and created prescriptions making use of marine drugs. In the Tang and Song period, the number of marine Chinese materia medica species and corresponding prescriptions apparently increased. The cognitions of the property, flavor, efficacy as well as the compatible principle of marine Chinese materia medica was further deepened and the scope of their treatment also significantly expanded. In the Ming and Qing dynasties, the cognition of the marine Chinese materia medica was mainly the conclusions of the previous experience. After the founding of the People's Republic of China (PRC), with the development of science and technologies, the ability of exploiting and utilizing the marine Chinese materia medica by people dramatically increased, and the species of marine Chinese materia medica reached more than one thousand. However, the development of marine Chinese materia medica is confronted with new problems; although the number of species of marine Chinese materia medica increased, the understanding of their property and flavor is obviously lagging behind, which seriously affects the clinical application of marine Chinese materia medica.

Ion-beam-induced reactions in Ni thin films on BP(100) have been investigated and compared with the results of the thermal reaction. The full reaction of Ni layer with BP induced by energetic heavy ion bombardments (600 keV Xe) was observed at 200degC and the formation of the crystalline phase corresponding to a composition of Ni 4 BP was observed. Amorphous layer with the same composition was formed by the bombardments below RT. For thermally annealed samples the reaction of the Ni layer on BP started at temperatures between 350degC and 400degC and full reaction was observed at 450degC. Metal-rich ternary phase or mixed binary phase is thought to be the first crystalline phase formed both in the ion-beam-induced and in the thermally induced reactions. The crystalline phase has the same composition and X-ray diffraction pattern both for ion-beam-induced and thermal reactions. Linear dependence of the reacted thickness on the ion fluence was also observed. The authors would like to express their sincere gratitude to Jian Li and Shi-Qing Wang for X-ray diffraction measurements at Cornell University. One of the authors (N.K.) acknowledge the Agency of Science and Technology of Japan for the financial support of his stay at Cornell. We also acknowledge Dr. H. Tanoue at ETL for his help in ion bombardment experiments. (author)

We report on research into building a cyberinfrastructure for Chinese biographical and geographic data. Our cyberinfrastructure contains (i) the McGill-Harvard-Yenching Library Ming Qing Women's Writings database (MQWW), the only online database on historical Chinese women's writings, (ii) the China Biographical Database, the authority for Chinese historical people, and (iii) the China Historical Geographical Information System, one of the first historical geographic information systems. Key to this integration is that linked databases retain separate identities as bases of knowledge, while they possess sufficient semantic interoperability to allow for multidatabase concepts and to support cross-database queries on an ad hoc basis. Computational ontologies create underlying semantics for database access. This paper focuses on the spatial component in a humanities cyberinfrastructure, which includes issues of conflicting data, heterogeneous data models, disambiguation, and geographic scale. First, we describe the methodology for integrating the databases. Then we detail the system architecture, which includes a tier of ontologies and schema. We describe the user interface and applications that allow for cross-database queries. For instance, users should be able to analyze the data, examine hypotheses on spatial and temporal relationships, and generate historical maps with datasets from MQWW for research, teaching, and publication on Chinese women writers, their familial relations, publishing venues, and the literary and social communities. Last, we discuss the social side of cyberinfrastructure development, as people are considered to be as critical as the technical components for its success.

Full Text Available Yanyan Yu, Gaoxing Su, Hongyan Zhu, Qing Zhu, Yong Chen, Bohui Xu, Yuqin Li, Wei Zhang School of Pharmacy, Nantong University, Nantong, People’s Republic of China Abstract: In this study, we fabricated a novel electrochemical biosensing platform on the basis of target-triggered proximity hybridization-mediated isothermal exponential amplification reaction (EXPAR for ultrasensitive protein analysis. Through rational design, the aptamers for protein recognition were integrated within two DNA probes. Via proximity hybridization principle, the affinity protein-binding event was converted into DNA assembly process. The recognition of protein by aptamers can trigger the strand displacement through the increase of the local concentrations of the involved probes. As a consequence, the output DNA was displaced, which can hybridize with the duplex probes immobilized on the electrode surface subsequently, leading to the initiation of the EXPAR as well as the cleavage of duplex probes. Each cleavage will release the gold nanoparticles (AuNPs binding sequence. With the modification of G-quadruplex sequence, electrochemical signals were yielded by the AuNPs through oxidizing 3,3',5,5'-tetramethylbenzidine in the presence of H2O2. The study we proposed exhibited high sensitivity toward platelet-derived growth factor BB (PDGF-BB with the detection limit of 52 fM. And, this method also showed great selectivity among the PDGF isoforms and performed well in spiked human serum samples.

The data mining technique is adopted to analyze characteristics and rules of acupoint and meridian selection of acupuncture-moxibustion for treatment of vertigo at different time periods in the ancient. The data is collected from literature regarding acupuncture-moxibustion from the pre-Qin period to the end of Qing Dynasty, so as to establish a clinical literature database of ancient acupuncture-moxibustion for treatment of vertigo. Data mining method is applied to analyze the commonly used meridians, acupoints and special acupoints in different dynasties, also possible rules are explored. Totally 82 pieces of prescription of acupuncture-moxibustion for treatment of vertigo are included. In the history the leading selection of acupoitns are Fengchi (GB 20), Hegu (LI 4), Shangxing (GV 23) and Jiexi (ST 41) while that of meridians are mainly three yang meridians of foot and the Governor Vessel, especially the acupoints on the Bladder Meridian of foot yangming had the highest utilization rate, accounting for 23.04%. The acupoint selection is characterized by special acupoint, accounting for 80.6%, among which the crossing points are the most common choice. Distal-proximal acupoints combination is the most frequent method. The results indicate that the ancient acupuncture-moxibustion for treatment of vertigo focused on acupoints in the yang meridians, and the specific acupoints play an essential role in prescription; also the principle of syndrome differentiation and selecting acupoints along the meridians could be seen.

A method for the direct determination of trace rare earth elements in ancient porcelain samples by slurry sampling fluorinating electrothermal vaporization inductively coupled plasma mass spectrometry was developed with the use of polytetrafluoroethylene as fluorinating reagent. It was found that Si, as a main matrix element in ancient porcelain sample, could be mostly removed at the ashing temperature of 1200 deg. C without considerable losses of the analytes. However, the chemical composition of ancient porcelain sample is very complicated, which makes the influences resulting from other matrix elements not be ignored. Therefore, the matrix effect of ancient porcelain sample was also investigated, and it was found that the matrix effect is obvious when the matrix concentration was larger than 0.8 g l -1 . The study results of particle size effect indicated that when the sample particle size was less than 0.057 mm, the particle size effect is negligible. Under the optimized operation conditions, the detection limits for rare earth elements by fluorinating electrothermal vaporization inductively coupled plasma mass spectrometry were 0.7 ng g -1 (Eu)-33.3 ng g -1 (Nd) with the precisions of 4.1% (Yb)-10% (La) (c = 1 μg l -1 , n = 9). The proposed method was used to directly determine the trace rare earth elements in ancient porcelain samples produced in different dynasty (Sui, Ming and Qing), and the analytical results are satisfactory

Since its domestication over 100 years ago, the laboratory rat has been the preferred experimental animal in many areas of biomedical research (Lindsey and Baker The laboratory rat. Academic, New York, pp 1-52, 2006). Its physiology, size, genetics, reproductive cycle, cognitive and behavioural characteristics have made it a particularly useful animal model for studying many human disorders and diseases. Indeed, through selective breeding programmes numerous strains have been derived that are now the mainstay of research on hypertension, obesity and neurobiology (Okamoto and Aoki Jpn Circ J 27:282-293, 1963; Zucker and Zucker J Hered 52(6):275-278, 1961). Despite this wealth of genetic and phenotypic diversity, the ability to manipulate and interrogate the genetic basis of existing phenotypes in rat strains and the methodology to generate new rat models has lagged significantly behind the advances made with its close cousin, the laboratory mouse. However, recent technical developments in stem cell biology and genetic engineering have again brought the rat to the forefront of biomedical studies and enabled researchers to exploit the increasingly accessible wealth of genome sequence information. In this review, we will describe how a breakthrough in understanding the molecular basis of self-renewal of the pluripotent founder cells of the mammalian embryo, embryonic stem (ES) cells, enabled the derivation of rat ES cells and their application in transgenesis. We will also describe the remarkable progress that has been made in the development of gene editing enzymes that enable the generation of transgenic rats directly through targeted genetic modifications in the genomes of zygotes. The simplicity, efficiency and cost-effectiveness of the CRISPR/Cas gene editing system, in particular, mean that the ability to engineer the rat genome is no longer a limiting factor. The selection of suitable targets and gene modifications will now become a priority: a challenge where

Taking the cases of two Korean court astronomers' journeys to Beijing in the seven-teenth and eighteenth centuries, this article examines how the political hierarchy between the Qing and Chosŏn dynasties conditioned Korean astronomers' effort to learn the Shixian li, the official calendrical system of the Qing. The difficulties the Korean astronomers met in their missions to Bei-jing, the measures of the Chosŏn court to support the astronomers' travel, and the actual process of the two astronomers' mission are to be examined. How then did the Korean astronomers view their mission and its difficulties? Curiously, they did not consider the travel to Beijing only as hardships to be avoided;rather, they took it as an opportunity to enhance their socio-professional interests. Sig-nificantly, they portrayed themselves as the astronomers of a“marginal state,” who could not expect to be competent in their specialty without paying pilgrimages to the imperial metropolis. This rhetoric of modesty reflected the puzzled position of the Korean official astronomers, who had to promote their socio-cultural interests only by negating their ability to be competent in their specialty on their own.%金尚范和许远分别是17世纪中叶和18世纪初期朝鲜宫廷天文学家的代表人物，在引进大清时宪历这件事上，做出了很大的贡献。文章试图从微观的角度出发，拟对金尚范和许远赴北京学习时宪历计算法的具体过程进行更加深入地探索。主要从天文学家们在北京旅行时遇到了怎样的困难，朝廷为他们的旅行提供过哪些制度方面的帮助，以及他们的实际学习是以怎样的方式进行的，这样几个方面来进行考察。同时，由此来揭示朝清之间的政治等级关系是怎样在社会与认识论的角度，制约天文学传播之具体过程的；朝鲜天文学者们对此又是怎样认识的，做出了哪些对应。通过对�

Caisson is one of the important representations of the Minnan (southern Fujian) temple architecture craft techniques and decorative aesthetics. The special component design and group building method present the architectural thinking and personal characteristics of great carpenters of Minnan temple architecture. In late Qing Dynasty, the appearance and style of caissons of famous temples in Taiwan apparently presented the building techniques of the great carpenters. However, as the years went by, the caisson design and craft techniques were not fully inherited, which has been a great loss of cultural assets. Accordingly, with the caisson of Fulong temple, a work by the well-known great carpenter in Tainan as an example, this study obtained the thinking principles of the original design and the design method at initial period of construction through interview records and the step of redrawing the "Tng-Ko" (traditional design, stakeout and construction tool). We obtained the 3D point cloud model of the caisson of Fulong temple using 3D laser scanning technology, and established the 3D digital model of each component of the caisson. Based on the caisson component procedure obtained from interview records, this study conducted the digital simulation of the caisson component to completely recode and present the caisson design, construction and completion procedure. This model of preserving the craft techniques for Minnan temple caisson by using digital technology makes specific contribution to the heritage of the craft techniques while providing an important reference for the digital preservation of human cultural assets.

The Historical Foundations of Religious Restrictions in Contemporary China

Full Text Available The ruling Chinese Communist Party (CCP abolished its total ban on religious activities in 1982. However, the distrust that the CCP feels for religions remains obvious today, and the religious restrictions in contemporary China remain tight. Conventional wisdom tells us that the official atheist ideology of Marxism-Leninism is the main reason behind the CCP’s distrust for, and restriction of, religion. However, taking a historical institutionalist perspective, this paper argues that the religious restrictions in contemporary China are in fact rooted in the fierce political struggles of the country’s two major revolutions in the first half of the twentieth century. Without the support of religious groups, the Nationalist Republicans would have found it difficult to survive and succeed in overthrowing the Qing Dynasty during the Chinese Republican Revolution in the first decade of the twentieth century. Likewise, without cooperating with a wide range of religious groups, the CCP would have struggled to defeat the Nationalist regime and the Japanese invaders in the Chinese Communist Revolution between 1920s and 1940s. Thanks to the collaborations and struggles with various religious groups during the two revolutions which lead to its eventual ascent to power, the CCP thoroughly understands the organisational strength and mobilising capability embedded within religious groups. The tight restrictions on religious affairs in contemporary China is therefore likely to stem from the CCP’s worry that prospective competitors could mobilise religious groups to challenge its rule through launching, supporting, or sponsoring collective actions.

A number of studies have revealed that salidroside exhibits neuroprotective activities, including anti-Alzheimer’s disease, anti-Parkinson’s disease, anti-Huntington’s disease, anti-stroke, anti-depressive effects, and anti-traumatic brain injury; it is also useful for improving cognitive function, treating addiction, and preventing epilepsy. The mechanisms underlying the potential protective effects of salidroside involvement are the regulation of oxidative stress response, inflammation, apoptosis, hypothalamus-pituitary-adrenal axis, neurotransmission, neural regeneration, and the cholinergic system. Being free of side effects makes salidroside potentially attractive as a candidate drug for the treatment of neurological disorders. It is evident from the available published literature that salidroside has potential use as a beneficial therapeutic medicine with high efficacy and low toxicity to the central nervous system. However, the definite target protein molecules remain unclear, and clinical trials regarding this are currently insufficient; thus, guidance for further research on the molecular mechanisms and clinical applications of salidroside is urgent.

Yao, S.

2015-08-01

Since the Yuan Dynasty, the belief of Matsu had started to spread from the birthplace to the northern coastal areas in China. Matsu worship developed to the pinnacle with the official promotion on account of the government's dependence on grain transported by sea since the mid-Qing Dynasty. A large amount of Matsu temples emerged in coastal cities of Bohai Rim where it still keeps a large number of them until now. It has much relationship between the spread of Matsu culture and the flow of Fujian population. It was one of the main building way that the Matsu temples attached to the local hall of Fujian in Bohai Rim. The Hall of Fujian in Yantai, Which was built with materials taken from Fujian, in the feature of traditional architectural style from QuanZhou, is very different from the local building style of Yantai. This case indicates that maritime culture of the south area had spread and developed in the north areas under the promotion of the population flow and the economic transaction. The essay introduces briefly about the development of Matsu culture in Bohai Rim and takes the case study of the Hall of Fujian in Yantai analyzing its causes and features, and the value as Matsu heritage. Then the paper will discuss the conservation of Matsu culture mere include the tangible and the intangible culture heritage around the origin area, the heritages of the spread area also have the same importance significance. With the evolution of the society, it calls urgent attention and protection of Matsu culture in Bohai Rim.

In this work, we tuned the magnetostructural transformation and the coupled magnetocaloric properties of Mn48‑x V x Ni42Sn10 (x = 0, 1, 2, and 3) ferromagnetic shape memory alloys prepared by means of partial replacement of Mn by V. It is observed that the martensitic transformation temperatures decrease with the increase of V content. The shift of the transition temperatures to lower temperatures driven by the applied field, the metamagnetic behavior, and the thermal hysteresis indicates the first-order nature for the magnetostructural transformation. The entropy changes with a magnetic field variation of 0–5 T are 15.2, 18.8, and 24.3 {{J}}\\cdot {kg}}-1\\cdot {{{K}}}-1 for the x = 0, 1, and 2 samples, respectively. The tunable martensitic transformation temperature, enhanced field driving capacity, and large entropy change suggest that Mn48‑x V x Ni42Sn10 alloys have a potential for applications in magnetic cooling refrigeration.

Lessons in ambivalence: The Shanghai Municipal Council's opium policies, 1906-1917.

Shanghai was considered to be a "capital of opium" in modern China, hence the history of opium in the city has received significant attention. In the Shanghai International Settlement, where Chinese and foreigners lived as neighbours, drugs were considered by the administration as both "trouble maker", and important financial resource. This paper explores how the Shanghai Municipal Council (SMC), the most senior governing body in the settlement, used its position to maximize political and economic profit from the trade and consumption of opium. The paper is based on documentary analysis of records of the SMC board meetings and other related material stored at Shanghai Municipal Archives. Interpretive approaches were used to analyze the shifting SMC strategies on opium consumption, the competing power relations and the way they were negotiated between actors with a stake in the region, including semi-colonialism and world systems analysis. With the dual purpose of preventing damage and enhancing municipal management, the SMC introduced a licensing system permitting the consumption and trade of drugs. However, the anti-opium policies of the late Qing government and the Anglo-Chinese 10 Year Agreement meant SMC had to shut down opium "houses" (opium dens) and "shops" (for the sale of opium to be consumed off the premises). Over almost a decade, the SMC shifted emphasis from political regulation of a social, recreational practice to maximizing financial benefit. In the process, SMC made full use of the opportunities it gained from a period of ambivalent Chinese and British power relations and local community rule. Copyright © 2016 Elsevier B.V.

After the middle of the Ming dynasty, the Chinese feudal system began to show some influence of capitalism in its production models. Changes began to take place in its political and economic systems. In 1723, a new method of household taxation was adopted to replace the traditional taxation system, which had been based upon the population of each household. Under the new system, taxation was based upon the size of the land each household owned. As a result of this change, the population showed rapid growth. Intellectuals began to form the concept of curbing excessive population growth. They also began to pay attention to the problems of adequate material supplies, overpopulation, and possible solutions. Chinese intellectuals and scholars of the late Ming and Qing dynasties, including Xu Guangqi, Hong Liangji, Wang Shifeng, and Xue Fucheng realized the serious nature of population growth. In fact, the population figure doubledever 30 years on a regular basis. The rapid population growth caused a decline in the living standard, higher prices for consumer goods, unemployment, a decline in the population quality, and social disorders. Hong Liangji suggested that natural disasters such as floods and droughts could help reduce the population, and that improvement in agriculture, emigration, and tax reductions could promote production. Wang Shifeng was in favor of using severe laws and restrictions on marriage to control population. Xue Fucheng proposed the idea of imitating Western countries to develop capitalism and industries and increase employment opportunities to reduce the pressure of the rapid population growth.

In Oriental countries, combinations of Chinese herbal products (CHPs) are often utilized as therapeutic agents for chronic obstructive pulmonary disease (COPD). The effects of CHPs on COPD have been previously reported. This study aimed to analyze the frequency of prescription and usage of CHPs in patients with COPD in Taiwan. In this nationwide population-based cross-sectional study, 19,142 patients from a random sample of one million individuals in the Longitudinal Health Insurance Database 2000 (LHID 2000) of the National Health Insurance Research Database (NHIRD) were enrolled from 2000 to 2011. The multiple logistic regression method was used to evaluate the adjusted odds ratios for the utilization of CHPs. For patients with COPD, there was an average of 6.31 CHPs in a single prescription. The most frequently prescribed CHP for COPD was Xiao-Qing-Long-Tang (XQLT) (2.6%), and the most commonly used combination of two formula CHPs was XQLT with Ma-Xing-Gan-Shi-Tang (MXGST) (1.28%). The most commonly used single CHP for COPD was Bulbus Fritillariae (3.65%), and the most commonly used combination of two single CHPs was Bulbus Fritillariae with Puerariae Lobatae (1.09%). These results provide information regarding personalized therapies and may promote further clinical experiments and pharmacologic research on the use of CHPs for the management of COPD. Furthermore, we found that TCM usage was more prevalent among men, younger, manual workers, residents of Northern Taiwan, and patients with chronic bronchitis and asthma. This information on the distribution of TCM usage around the country is valuable to public health policymakers and clinicians.

However, the mechanisms underlying the effect of carvacrol in human oral squamous cell carcinoma (OSCC remain unclear. Here, we report that carvacrol significantly inhibits tumor cell proliferation, metastasis and invasion, and induces apoptosis in OSCC. Our results demonstrated that the molecular mechanisms of the effect of carvacrol in Tca-8113 induces G1/S cell cycle arrest through downregulation of CDK regulator CCND1 and CDK4, and upregulation of CDK inhibitor P21. Further analysis demonstrated that carvacrol also inhibited Tca-8113 cells’ clone formation in clonogenic cell survival assay. Student’s t-test (two-tailed was used to compare differences between groups, and the significance level was P<0.01. Then, treatment of Tca-8113 cells with carvacrol resulted in downregulation of Bcl-2, Cox2, and upregulation of Bax. Carvacrol significantly inhibited the migration and invasion of human OSCC cells by blocking the phosphorylation of FAK and MMP-9 and MMP-2, transcription factor ZEB1, and β-catenin proteins’ expression. Taken together, these results provide novel insights into the mechanism of carvacrol and suggest potential therapeutic strategies for human OSCC.Keywords: carvacrol, proliferation, metastasis and invasion, oral squamous cell carcinoma

Full Text Available Translation studies in English and Chinese has long been of great interest to academics. Yet, Chinese scholars who have translation training and linguistic expertise are often found to “give excessive attention to listing facts and probing linguistic matters, to the neglect of the cultural and contextual considerations that have given rise to translation in China in the first place” (Lin, 2002, p. 170. Much emphasis has been placed on translation strategies, while translation “in connection with power and patronage” (Lefereve, 1992, p. 10 is overlooked, leaving “existing ideology” or “existing poetics” (Lefereve, 1992, p. 10, such as gender unexplored. In light of this, this paper attempts to take the literary and cultural approach and focus on examining the gender ideologies in Pu Songling’s Strange Stories from a Chinese Studio (1740 and Herbert Giles’ English rendition (1880. By comparing the source and target texts, the paper reveals that in many of Pu Songling’s stories, spirit-freelove and sexual pleasure are celebrated. A witty parody of the imitative structures of gender can be found in Pu Songling’s “Painted Skin” too. Unfortunately, to a large extent, such transgressive gender views are repressed in Giles’ English rendition.

The Yellow Emperor's Classic of Internal Medicine, created in the Warring States period (475 to 221 BC) described a phenomenon whereby the eastern, western, northern, southern, and central regions were liable to different diseases. It brought forward the principle of treatment in accordance with local conditions. Lv's Spring and Autumn Annals, Huai Nan Tzu (Huainanzi), and the Regiment of Health (Yangshenglun) in the Qin, Han, Wei, Jin, and Southern and Northern Dynasties all describe regional diseases such as goiter (endemic goiter) and yellowish teeth (dental fluorosis) as being caused by geologic and climatic factors. Zhang (miasma), first mentioned in the Han Dynasty, was considered related to the summer heat and dampness particular to the geographical environment of the south. Zhang was further associated with malaria in the Jin Dynasty. General Treatise on the Etiology and Symptomology of Diseases (Zhubingyuanhou Lun), in the Sui Dynasty, held that as a type of poisonous gas, Zhang was the predisposing cause of malaria, seasonal disease, and barbiers, among other conditions. General Guide (Zhinan Zonglun), in the Southern Song Dynasty, regarded Zhang malaria as a separate disease. Healthy Prescription in the Southern Wuling District (Lingnan Weisheng Fang), in the late Song and early Yuan Dynasties, explicitly put forward the concepts of cold Zhang, hot Zhang, and lockjaw Zhang. Guidelines for Treatment of Zhang Malaria (Zhangnue Zhinan), in the Ming Dynasty, maintained that cold Zhang was equivalent to malaria, while hot Zhang and lockjaw Zhang were equivalent to cold damage, the latter of which can be treated by prescriptions for cold damage. Records on Zhang gas and Zhang disease decreased during the Ming and Qing Dynasties.

Full Text Available Ying-dong Cheng, Hua Yang, Guo-qing Chen, Zhi-cao Zhang Department of General Surgery, Xinqiao Hospital, Third Military Medical University, Chongqing, People's Republic of China Abstract: The survival rate of patients with metastatic colorectal cancer (mCRC has significantly improved with applications of molecularly targeted drugs, such as bevacizumab, and led to a substantial improvement in the overall survival rate. These drugs are capable of specifically targeting the inherent abnormal pathways in cancer cells, which are potentially less toxic than traditional nonselective chemotherapeutics. In this review, the recent clinical information about molecularly targeted therapy for mCRC is summarized, with specific focus on several of the US Food and Drug Administration-approved molecularly targeted drugs for the treatment of mCRC in the clinic. Progression-free and overall survival in patients with mCRC was improved greatly by the addition of bevacizumab and/or cetuximab to standard chemotherapy, in either first- or second-line treatment. Aflibercept has been used in combination with folinic acid (leucovorin–fluorouracil–irinotecan (FOLFIRI chemotherapy in mCRC patients and among patients with mCRC with wild-type KRAS, the outcomes were significantly improved by panitumumab in combination with folinic acid (leucovorin–fluorouracil–oxaliplatin (FOLFOX or FOLFIRI. Because of the new preliminary studies, it has been recommended that regorafenib be used with FOLFOX or FOLFIRI as first- or second-line treatment of mCRC chemotherapy. In summary, an era of new opportunities has been opened for treatment of mCRC and/or other malignancies, resulting from the discovery of new selective targeting drugs.

In this study, we investigated the beneficial effects of rhein in inflammation models in the transgenic zebrafish line TG (corolla eGFP, in which both macrophages and neutrophils express eGFP and RAW264.7 macrophages. We found that the tail-cutting-induced migration of immune cells was significantly reduced in transgenic zebrafish treated with rhein. In addition, the production of proinflammatory cytokines, including IL-6, IL-1β, and tumor necrosis factor-α, were significantly reduced in lipopolysaccharide (LPS-induced RAW264.7 macrophages treated with rhein. Parallel to the inhibition of proinflammatory cytokines, rhein significantly reduced phosphorylation levels of NF-κB p65 and inducible nitric oxide synthase, as well as COX-2 protein expression levels. Furthermore, rhein significantly reduced NALP3 and cleaved IL-1β expression in LPS + ATP-induced RAW264.7 macrophages. Thus, the present study demonstrates that rhein may exhibit its anti-inflammatory action via inhibition of NF-κB and NALP3 inflammasome pathways.

HEF1 expression has not previously been reported in urinary bladder carcinoma, and little is known about its prognostic significance. The aim of this study was to evaluate the expression patterns of HEF1 in urinary bladder carcinoma and to investigate its prognostic significance. HEF1 expression was analyzed by immunohistochemistry using tissue microarray. A significant relationship between HEF1 expression and sex, tumor size, number of tumors, invasion depth, lymph node metastasis, and distant metastasis was found, and high expression of HEF1 was associated with worse overall survival when compared to low expression of HEF1. Multivariate analysis showed that HEF1 expression was an independent prognostic factor for overall survival in urinary bladder carcinoma. We investigated HEF1 expression in urinary bladder carcinoma and found that high HEF1 expression was associated with advanced stage, large tumor size, and shortened progression-free survival. Although the biologic function of HEF1 in urinary bladder carcinoma remains unknown, the expression of HEF1 can provide new prognostic information for disease progression. Keywords: human enhancer of filamentation 1, progression-free survival, immunohistochemistry, metastasis, bladder cancer

During the Chinese dynasties of Sui and Tang, neighboring minority groups were forced to migrate to less settled areas of China. During the Song dynasty (960-1279) the Han government lost control of neighboring ethnic groups. Ethnically dominated states on their own expanded to the hinterlands, formed the national governments of Yuan and Qing, and established the local power of Liao and Jin in Han-dominated areas. During the Han dynasty the movement of minorities fulfilled the purpose of helping cultivate undeveloped land. The Han governments of feudal China held compulsory migration policies and policies encouraging minorities to move to less inhabited places. Han governments prior to the Tang and Song dynasties held policies favorable to minority settlements. During the Tang dynasty land was given to minority settlers. During the Song dynasty the Han government held a policy which prohibited taxation and harassment of new minority settlers. Minorities gained improved living conditions and the government achieved pacification. Resettlement of minorities either from forced or voluntary migration facilitated communication with the Han and promoted the exchange of culture, but also intensified ethnic conflict. The reason for the ethnic conflict was a question of control. Ethnic governments encouraged in-migration and adopted policies of compulsory and voluntary migration. Ethnic minorities in the north and west practiced mainly compulsory migration. Ethnic conflict in the Qin and Han dynasties occurred between the Han and the Huns. During the Eastern Jin and Northern dynasties minority governments captured Han and other ethnic groups. The rule of minority government was strengthened by voluntary migration. The frequent power shifts in ancient China contributed to the blending of Chinese nationalities.

Alzheimer's disease (AD) is characterized by large deposits of amyloid β (Aβ) peptide. Aβ is known to increase reactive oxygen species (ROS) production in neurons, leading to cell death. In this study, we screened 15 plant seeds' aqueous extracts (PSAE) for inhibitory effects on Aβ (25-35)-induced cell death using hippocampus neurons (HIPN). Fifteen chosen plants were nine medical herbs (Japanese honeywort, luffa, rapeseed, Chinese colza, potherb mustard, Japanese radish, bitter melon, red shiso, corn, and kaiware radish) and six general commercial plants (common bean, komatsuna, Qing geng cai, bell pepper, kale, and lettuce). PSAE were measured for total phenolic content (TPC) with the Folin-Ciocalteu method, and the 2-diphenyl-1-picryl-hydrazyl (DPPH) radical scavenging effect of each seed extract was measured. To find a protectant against Aβ-induced oxidative stress, we screened 15 PSAE using a 2', 7'-dichlorofluorescein diacetate assay. To further unravel the anti-inflammatory effects of PSAE on Aβ-induced inflammation, PSAE were added to HIPN. The neuroprotective effects of the PSAE were evaluated by Cell Counting Kit-8 assay, measuring the cell viability in Aβ-induced HIPN. TPC of 15 PSAE was in the range of 0.024-1.96 mg of chlorogenic acid equivalents/gram. The aqueous extracts showed antioxidant activities. Furthermore, intracellular ROS accumulation resulting from Aβ treatment was reduced when cells were treated with some PSAE. Kale, bitter melon, kaiware radish, red shiso, and corn inhibited tumor necrosis factor-alpha secretion by the Aβ-stimulated neurons and all samples except Japanese honeywort showed enhancement of cell survival. From these results, we suggest that some plant seed extracts offer protection against Aβ-mediated cell death.

Magnetic nanoparticles of Fe3O4 (MgNPs-Fe3O4 can enhance the delivery and efficacy of anticancer drugs. We investigated the effects of MgNPs-Fe3O4 or DTX alone, and in combination with prostate cancer cell growth in vitro, as well as with the mechanism underlying the cytotoxic effects. MgNPs-Fe3O4 caused dose-dependent increases in reactive oxygen species levels in DU145, PC-3, and LNCaP cells; 8-hydroxydeoxyguanosine levels were also elevated. MgNPs-Fe3O4 alone reduced the viability of LNCaP and PC-3 cells; however, MgNPs-Fe3O4 enhanced the cytotoxic effect of a low dose of DTX in all three cell lines. MgNPs-Fe3O4 also augmented the percentage of DU145 cells undergoing apoptosis following treatment with low dose DTX. Expression of nuclear transcription factor κB in DU145 was not affected by MgNPs-Fe3O4 or DTX alone; however, combined treatment suppressed nuclear transcription factor κB expression. These findings offer the possibility that MgNPs-Fe3O4–low dose DTX combination therapy may be

Giuseppe Castiglione (Lang Shining, precursor de la primera mundialización pictórico-arquitectónica

Full Text Available La obra del hermano lego jesuita Giuseppe Castiglione (nombre chino, Lang Shining, 1688-1766, desarrollada en la China Qing, no fue suficientemente conocida sino hasta el siglo xx, y se ha investigado muy poco sobre su papel precursor de la primera mundialización artística. Su aproximación a China fue primordialmente de carácter apostólico, como consecuencia de la acción misional. Esta misión estuvo basada en un proceso inculturador fundamentado, a su vez, en el intercambio de las ciencias y las artes. Este artículo pone de manifiesto el riguroso conocimiento que sobre perspectiva matemática lineal había adquirido Castiglione en Europa, y la trascendencia que tuvo en la hibridación cultural y artística en la China del siglo xviii. Su posible repercusión en manifestaciones artísticas posteriores en otros territorios constituye el tema central del trabajo. Desde el punto de vista artístico, dada su privilegiada posición en la corte imperial, el artista jesuita jugó un papel decisivo en los nuevos métodos pictórico-arquitectónicos que se desarrollaron en la dinastía Qing. Sus murales, retratos, caballos, flores y pájaros, fueron elogiados y admirados por el emperador Qianlong, y mucho tiempo después por diseñadores y pintores europeos. Al simbolismo y la sensibilidad de la pintura asiática, Castiglione añadió el misterio del ilusionismo mágico que encierra la perspectiva matemática lineal europea, que contenía la llave y el secreto del conocimiento geométrico de Lang Shining. Sin embargo, sus efectos no fueron exclusivamente artísticos, sino que en muchos casos tuvieron una vigorosa dimensión apostólica. La dimensión religiosa que presuponemos en las pinturas de los artistas jesuitas fue una herramienta esencial en el proceso de inculturación; en este sentido, G. Castiglione usó la perspectiva no sólo como una técnica que gustaba a los emperadores, y fundamentalmente al emperador Qianlong, sino también como

Full Text Available Plant phenolics can have applications in pharmaceutical and other industries. To identify and quantify the phenolic compounds in Helianthus tuberosus leaves, qualitative analysis was performed by a reversed phase high-performance liquid chromatography coupled with tandem mass spectrometry (HPLC-MS/MS and quantitative analysis by HPLC. Ten chlorogenic acids (CGAs were identified (3-o-caffeoylquinic acid, two isomers of caffeoylquinic acid, caffeic acid, p-coumaroyl-quinic acid, feruloylquinic acid, 3,4-dicaffeoyquinic acid, 3,5-dicaffeoylquinic acid, 1,5-dicaffeoylquinic acid, and 4,5-dicaffeoylquinic acid by comparing their retention times, UV-Vis absorption spectra, and MS/MS spectra with standards. In addition, four other phenolic compounds, including caffeoyl glucopyranose, isorhamnetin glucoside, kaempferol glucuronide, and kaempferol-3-o-glucoside, were tentatively identified in Helianthus tuberosus leaves for the first time. The 3-o-caffeoylquinic acid (7.752 mg/g DW, 4,5-dicaffeoylquinic acid (5.633 mg/g DW, and 3,5-dicaffeoylquinic acid (4.900 mg/g DW were the major phenolic compounds in leaves of Helianthus tuberosus cultivar NanYu in maturity. The variations in phenolic concentrations and proportions in Helianthus tuberosus leaves were influenced by genotype and plant growth stage. Cultivar NanYu had the highest concentration of phenolic compounds, in particular 3-o-caffeoylquinic acid and 4,5-dicaffeoylquinic acid compared with the other genotypes (wild accession and QingYu. Considering various growth stages, the concentration of total phenolics in cultivar NanYu was higher at flowering stage (5.270 mg/g DW than at budding and tuber swelling stages. Cultivar NanYu of Helianthus tuberosus is a potential source of natural phenolics that may play an important role in the development of pharmaceuticals.

Variations of Synchrotron Radio Emissions from Jupiter's Inner Radiation Belt Yu-Qing Lou* Physics Department, Tsinghua Centre for Astrophysics (THCA), Tsinghua-National Astronomical Observatories of China (NAOC) joint Research Centre for Astrophysics, Tsinghua University, Beijing 100084, China We describe the basic phenommenology of quasi-periodic 40 minute (QP-40) polar burst activities of Jupiter and their close correlation with the solar wind speed variations at the Jovian magnetosphere. Physically, relativistic electrons of QP-40 bursts most likely come from the circumpolar regions of the inner radiation belt (IRB) which gives off intense synchroton radio emissions in a wide wavelength range. Such relativistic electron bursts also give rise to beamed low-frequency radio bursts along polar magnetic field lines with distinct polarizations from Jupiter's two polar regions. Jovian aurora activities are expected to be also affected by such QP-40 burst activities. We present evidence of short-term (typical timescales shorter than an hour) variabilities of the IRB at 6cm wavelength and describe recent joint radio telescope observation campaign to monitor Jupiter in coordination with JUNO spacecraft. Except for low-frequency polarization features, we anticipate JUNO to detect QP-40 activities from both polar regions during the arrival of high-speed solar wind with intermittency. References 1.

For example, the toxicity of chitosan nanoparticles, one of the most widely used drug/gene delivery vehicles, is largely unknown. In the present study, the zebrafish model was used for a safety evaluation of this nanocarrier.Methods: Chitosan nanoparticles with two particle sizes were prepared by ionic cross-linking of chitosan with sodium tripolyphosphate. Chitosan nanoparticles of different concentrations were incubated with zebrafish embryos, and ZnO nanoparticles were used as the positive control.Results: Embryo exposure to chitosan nanoparticles and ZnO nanoparticles resulted in a decreased hatching rate and increased mortality, which was concentration-dependent. Chitosan nanoparticles at a size of 200 nm caused malformations, including a bent spine, pericardial edema, and an opaque yolk in zebrafish embryos. Furthermore, embryos exposed to chitosan nanoparticles showed an increased rate of cell death, high expression of reactive oxygen species, as well as overexpression of heat shock protein 70, indicating that chitosan nanoparticles can cause physiological stress in zebrafish. The results also suggest that the toxicity of biodegradable nanocarriers such as chitosan nanoparticles must be addressed, especially considering the in vivo distribution of these nanoscaled particles.Conclusion: Our results add new insights into the potential toxicity of nanoparticles produced by

Geo-archaeological fieldwork conducted between 2010-2012 around Banda Aceh, Indonesia revealed stratigraphic evidence for one (possibly two) historic tsunami occurring in the decades after 1366±3. Between 2015 - 2017 we conducted an extensive landscape archaeology survey in 43 coastal villages spanning over 40 km to see if these past tsunamis impacted coastal settlement. In the first major systemic survey of its kind in Indonesia, we found and documented 995 archaeological sites ranging from the late 10th to 20th centuries CE, containing over 5,000 carved gravestones, and 50,000 ceramic sherds. The distribution of ceramic material suggests seven discrete areas of cultural activity before the 14th century CE tsunami. Our working hypothesis is that six of these sites were villages of local inhabitants who utilized imported ceramics. These started at the end of the 10th century and have evidence for activity through present day. However, detailed analysis of the chronology of the ceramics material strongly suggests that there was a notable reduction of activity between 1360 and 1450 CE (Figure 2), supporting the hypothesis that coastal settlements were disrupted by the historic tsunami. The distribution of ceramic material after 1500 CE across the survey area shows a gradual repopulation of pre-tsunami sites, as well as a significant expansion of activity starting at the end of the 16th Century, for all areas but Lamreh. The density of settlements increases during the late-Ming and Qing period, which corresponds to the rise of the Acehnese sultanate and the formation of the urban center of Banda Aceh, when the coastal settlement patterns closely resembled the areas devastated by the 2004 Indian Ocean tsunami.

This study evaluates the long-term effects of PTRAS on hypertension and renal function in elderly patients with ARAS.Methods: We conducted a retrospective cohort study of all patients who underwent PTRAS in the geriatric division of a tertiary medical center during the period 2003–2010. The clinical data were extracted from the medical records of each patient. Changes in blood pressure, antihypertensive treatment, and estimated glomerular filtration rate were analyzed before and after PTRAS.Results: Eighty-six stents in 81 elderly patients were placed successfully. The average age of the patients was 76.2 years (65–89 years. Mean follow-up was 31.3 months (range 12 –49 months. There was a significant decrease in both systolic and diastolic blood pressure at the third day after the PTRAS procedure and the reduction in blood pressure was constant throughout the follow-up period until 36 months after PTRAS. However, there was no marked benefit to renal function outcome during the follow-up period. The incidence of contrast-induced nephropathy was 9.9% in this study group. The rate of renal artery restenosis was 14.8%. The survival rate was 96.3% for 4 years after the procedure.Conclusion: It is beneficial to control blood pressure in elderly patients with ARAS up to 36 months after a PTRAS procedure.

Endosperm starch provides prime energy for cereal seedling growth. Cereal endosperm with repression of starch branching enzyme (SBE) has been widely studied for its high resistant starch content and health benefit. However, in barley and maize, the repression of SBE changes starch component and amylopectin structure which affects grain germination and seedling establishment. A high resistant starch rice line (TRS) has been developed through inhibiting SBEI/IIb, and its starch has very high resistance to in vitro hydrolysis and digestion. However, it is unclear whether the starch resists in situ degradation in seed and influences seedling growth after grain germination. In this study, TRS and its wild-type rice cultivar Te-qing (TQ) were used to investigate the seedling growth, starch property changes, and in situ starch degradation during seedling growth. The slow degradation of starch in TRS seed restrained the seedling growth. The starch components including amylose and amylopectin were simultaneously degraded in TQ seeds during seedling growth, but in TRS seeds, the amylose was degraded faster than amylopectin and the amylopectin long branch-chains with B-type crystallinity had high resistance to in situ degradation. TQ starch was gradually degraded from the proximal to distal region of embryo and from the outer to inner in endosperm. However, TRS endosperm contained polygonal, aggregate, elongated and hollow starch from inner to outer. The polygonal starch similar to TQ starch was completely degraded, and the other starches with long branch-chains of amylopectin and B-type crystallinity were degraded faster at the early stage of seedling growth but had high resistance to in situ degradation during TRS seedling growth. The B-type crystallinity and long branch-chains of amylopectin in TRS seed had high resistance to in situ degradation, which inhibited TRS seedling growth.

Water scarcity causes conflicts among natural resources, society and economy and reinforces the need for optimal allocation of irrigation water resources in a sustainable way. Uncertainties caused by natural conditions and human activities make optimal allocation more complex. An intuitionistic fuzzy multi-objective non-linear programming (IFMONLP) model for irrigation water allocation under the combination of dry and wet conditions is developed to help decision makers mitigate water scarcity. The model is capable of quantitatively solving multiple problems including crop yield increase, blue water saving, and water supply cost reduction to obtain a balanced water allocation scheme using a multi-objective non-linear programming technique. Moreover, it can deal with uncertainty as well as hesitation based on the introduction of intuitionistic fuzzy numbers. Consideration of the combination of dry and wet conditions for water availability and precipitation makes it possible to gain insights into the various irrigation water allocations, and joint probabilities based on copula functions provide decision makers an average standard for irrigation. A case study on optimally allocating both surface water and groundwater to different growth periods of rice in different subareas in Heping irrigation area, Qing'an County, northeast China shows the potential and applicability of the developed model. Results show that the crop yield increase target especially in tillering and elongation stages is a prevailing concern when more water is available, and trading schemes can mitigate water supply cost and save water with an increased grain output. Results also reveal that the water allocation schemes are sensitive to the variation of water availability and precipitation with uncertain characteristics. The IFMONLP model is applicable for most irrigation areas with limited water supplies to determine irrigation water strategies under a fuzzy environment.

However, the stress reactivity and emotional variations in women with premenstrual syndrome (PMS, who are especially sensitive to the variations in hormone cycles, have not been explained. Methods: The present study used an electroencephalogram (EEG stress evaluation test, a physiology stress evaluation test, and the positive affect and negative affect scale (PANAS to evaluate the stress reactivity pattern and emotional state of women with PMS. Results: The results showed that women with PMS had higher negative affect and lower positive affect compared with controls. Moreover, under stressful conditions, the women with PMS had a higher alpha activity and a lower respiration rate than the controls. The differences in stress reactivity and emotional states between women with PMS and controls were based on a covariant analysis with menstrual cycle (luteal and follicular phases as the covariate. Conclusion: The results demonstrated that, compared with controls, women suffering from PMS have a continuous abnormality in emotional state and stress reactivity, which was independent of the menstrual cycle.

We conducted a meta-analysis to reevaluate the association of Notch-1 expression with clinicopathological characteristics and prognosis of HCC. PubMed, Embase, Web of Science, and China National Knowledge Infrastructure were searched to look for relevant studies. The association between Notch-1 expression and clinicopathological parameters and overall survival (OS was then reassessed using the meta-analysis for odds ratio (OR or hazard ratio (HR and 95% confidence interval (CI. A total of seven studies, including 810 HCC patients, were eligible for the meta-analysis. Our data showed that high Notch-1 expression was able to predict poor OS (HR 1.50, 95% CI 1.17–1.83, P=0.0001. The pooled OR showed that high Notch-1 expression was significantly associated with tumor metastasis (OR 0.37, 95% CI 0.16–0.86, P=0.02 and tumor size >5 cm (OR 0.48, 95% CI 0.26–0.88, P=0.02. In contrast, there was no association between high Notch-1 expression and tumor differentiation, late TNM stage, tumor number, and portal vein invasion of HCC.

The cationic cholesterol derivative, N-(cholesterylhemisuccinoyl-amino-3-propyl-N, N-dimethylamine (DMAPA-chems liposome, was incubated with siRNA at different nitrogen-to-phosphate ratios to form stabilized, near-spherical siRNA/DMAPA-chems nanoparticles with sizes of 100–200 nm and zeta potentials of 40–50 mV. The siRNA/DMAPA-chems nanoparticles protected siRNA from nuclease degradation in 25% fetal bovine serum. The nanoparticles exhibited high cell uptake and Notch1 gene knockdown efficiency in SKOV3 cells at an nitrogen-to-phosphate ratio of 100 and an siRNA concentration of 50 nM. They also inhibited the growth and promoted the apoptosis of SKOV3 cells. These results may provide the potential for using cationic cholesterol derivatives as efficient nonviral siRNA carriers for the suppression of Notch1 activation in ovarian cancer cells.

An ongoing challenge for smart homes research for aging-in-place is how to make sense of the large amounts of data from in-home sensors to facilitate real-time monitoring and develop reliable alerts. The objective of our study was to explore the usefulness of a routine-based approach for making sense of smart home data for the elderly. Maximum variation sampling was used to select three cases for an in-depth mixed methods exploration of the daily routines of three elderly participants in a smart home trial using 180 days of power use and motion sensor data and longitudinal interview data. Sensor data accurately matched self-reported routines. By comparing daily movement data with personal routines, it was possible to identify changes in routine that signaled illness, recovery from bereavement, and gradual deterioration of sleep quality and daily movement. Interview and sensor data also identified changes in routine with variations in temperature and daylight hours. The findings demonstrated that a routine-based approach makes interpreting sensor data easy, intuitive, and transparent. They highlighted the importance of understanding and accounting for individual differences in preferences for routinization and the influence of the cyclical nature of daily routines, social or cultural rhythms, and seasonal changes in temperature and daylight hours when interpreting information based on sensor data. This research has demonstrated the usefulness of a routine-based approach for making sense of smart home data, which has furthered the understanding of the challenges that need to be addressed in order to make real-time monitoring and effective alerts a reality. ©Yasmin van Kasteren, Dana Bradford, Qing Zhang, Mohan Karunanithi, Hang Ding.

Full Text Available This paper is divided into three parts. The first part of the article is a brief review of the developmental history of ancient and modern cartography in China. It shows that China is one of the earliest countries in the world to create maps. China played an important role in the development of cartography in the world, and has made significant contributions to the development of cartography. Up till the Ming Dynasty in 15th Century, China's map and cartography had always been ahead of the Western countries, but fell behind only after the Qing Dynasty. The second part of the article describes the rapid development of China's mapping and cartography after the founding of the "New China", including the tremendous achievements in the areas of mapping and creation of national topographic maps, thematic maps and atlases, remote sensing cartography, computer-aided cartography, multimedia electronic maps, mobile communication maps, online maps, and theoretical research of cartography. China has caught up and reached the world's advanced level in cartography. The third part It proposes the direction and adjusted roles of mapping and cartography in China in the new century, and analyzes the opportunities, challenges and prospects of cartography in the era of big data, internet and artificial intelligence. Via visualization of 3D dynamic mapping, big data can show the spatial pattern and regional differentiation as well as temporal and spatial dynamic change of subjects and phenomena, and then make analysis and evaluation, forecast and early warning, zoning and layout, planning and design, management and regulation. Therefore cartography can play an important role in the era of big data. In the future, internet will become the main platform for map creation and application. Maps will be more popular, personalized, intelligent and practical.

Traditional Chinese medicine is one of the popular alternative treatments for cancer, mainly enhancing host immune response and reducing adverse effect of chemotherapy. This study first explored traditional Chinese medicine treatment effect on long-term survival of lung cancer patients. This study evaluated whether traditional Chinese medicine combined with conventional cancer treatment improved overall survival of lung cancer patients. We had conducted a retrospective cohort study on 111,564 newly diagnosed lung cancer patients in 2000-2009 from National Health Insurance Program database. A total of 23,803 (21.31%) patients used traditional Chinese medicine for lung cancer care. Eligible participants were followed up until 2011 with a mean follow-up period of 1.96 years (standard deviation 2.55) for non-TCM users and 3.04 years (2.85) for traditional Chinese medicine users. Patients with traditional Chinese medicine utilization were significantly more likely to have a 32% decreased risk of death [hazard ratio = 0.62; 95% confidence interval = 0.61-0.63], compared with patients without traditional Chinese medicine utilization after multivariate adjustment. We also observed a similar significant reduction risk across various subgroups of chronic lung diseases. Qing Zao Jiu Fei Tang was the most effective traditional Chinese medicine agent for mortality reduction both in the entire lung cancer (0.81; 0.72-0.91) and matched populations (0.86; 0.78-0.95). This study demonstrated adjunctive therapy with traditional Chinese medicine may improve overall survival of lung cancer patients. This study also suggested traditional Chinese medicine may be used as an adjunctive therapy for cancer treatment. These observational findings need being validated by future randomized controlled trials to rule out the possibility of effect due to holistic care.

Abstract Pneumonia is a frequent complication in dementia patients and is associated with high mortality rates. The aim of this retrospective cohort study was to determine whether traditional Chinese medicine (TCM) therapy can decrease pneumonia risk in dementia patients. The cohort dataset was obtained from the Longitudinal Health Insurance Database 2005, a sublibrary of the National Health Insurance Research Database, containing all medical data of 1 million beneficiaries, randomly selected from the all Insurers in year 2005. Newly diagnosed dementia patients (n = 9712) without pneumonia were analyzed from January 1997 to December 2003. After matching by sex, age, urban level, Charlson comorbidity index, insured amount, and comorbidities, 1376 pairs (1:1) of TCM and non-TCM users were acquired. Every dementia patient was individually recorded from 1997 to 2012 to identify pneumonia incidence (onset after 3 months of dementia diagnosis). Demographic characteristics, Charlson comorbidity index, comorbidities, behavioral and psychological symptoms of dementia, and psychotropic drugs were also investigated. Cox proportional regression was used to compute hazard ratios and 95% confidence intervals (CIs) after adjustment for the above-mentioned variables. There were 419 (30.5%) and 762 (55.4%) pneumonia cases in the TCM and non-TCM cohorts during a mean follow-up period of 7.6 years. The adjusted hazard ratios (95% CI) for pneumonia admission was 0.62 (0.55–0.70) for the TCM group. Patients who received TCM therapy at higher cumulative doses or for longer periods experienced increased protection from pneumonia admission. Ma-Xing-Gan-Shi-Tang, Yin-Qiao-San, and Xiao-Qing-Long-Tang might represent possible formulae reducing the incidence of pneumonia. TCM might be associated with a lower risk of pneumonia in dementia patients. PMID:27631269

The digging of Qingjiang Pu canal and the rise of Qingjiang Pu city are closely linked with Chen Xu-an who administered water transport for thirty years. He was a founder and establisher of the river system in Ming and Qing Dynasties. Chen Xuan followed the old canal———the sand river and dug Qingjiang Pu ( not named Qingjiang Pu) , most of which was dug on the old course of the original beneaped sand-river canal dug by Qiao Weiyue in Song dynasty ( called Qingjiang Pu after Yuan Yanyou five years) . Chen Xuan built four floodgates in the Qingjiang Pu canal, and the riverway between the Mopan mouth and the Yachen mouth was a newly section dug by Chen Xuan ( of course, it is not excluded that part of the other old rivers or water courses was used for this section) .%清江浦运河的开凿与清江浦城的兴起，与陈瑄息息相关，陈瑄督理河漕凡三十年，是明清时期漕运制度的确立者和奠基人。陈瑄循沙河旧渠，开凿清江浦(非命名清江浦)，大部分是在原来淤浅的宋乔维岳沙河运河(元延祐五年后称清江浦)旧渠上开凿的。陈瑄在清江浦运河上建四道闸，磨盘口至鸭陈口的这一段河道，是陈瑄新开挖的部分。

The process of human response to natural disasters and its mechanisms as revealed by historical events still has a broad significance for modern society. This study analyzed the disaster relief process and the social response for two floods in China: the Yongding River flood in 1801 and the Yellow River flood in 1841. These two floods reflect the different response processes between the national and provincial capitals during a stage of climate cooling and social transition in the Qing dynasty. Applying methods of historical documents analysis and qualitatively comparative analysis to the materials such as Relief Chronicles Authorized by the Emperor in XinYou and Flood Description in Bian Liang , it shows that: (1) In 1801, the central government took on a lead position, from flood surveying to relief processes. However, local government and gentries played an important role in 1841. (2) In 1801, the government successfully undertook a series of relief measures addressing production, housing, food prices, taxes, and water conservancy and administration. In 1841, the response measures were relatively simple, focusing mainly on providing shelter and food for victims. (3) The government carried out long-term disaster prevention measures such as dredging channels after the flood in 1801. In 1841, however, the efforts were focused mainly on emergency rescue. (4) Refugees in the 1801 flood were effectively managed by a centralized authority. In 1841, regulation of the flooding was delayed by corruption and conflicts between officers, leading to an expansion of the disaster's impact. Above results have led to the conclusion that disaster relief systems and response measures had a significant effect on the consequences of those floods. Various flood relief measures and natural disasters management regimes have implications for contemporary flood hazard mitigation.

Full Text Available Aim: Alzheimer′s disease (AD is characterized by large deposits of amyloid β (Aβ peptide. Aβ is known to increase reactive oxygen species (ROS production in neurons, leading to cell death. In this study, we screened 15 plant seeds′ aqueous extracts (PSAE for inhibitory effects on Aβ (25-35-induced cell death using hippocampus neurons (HIPN. Materials and Methods: Fifteen chosen plants were nine medical herbs (Japanese honeywort, luffa, rapeseed, Chinese colza, potherb mustard, Japanese radish, bitter melon, red shiso, corn, and kaiware radish and six general commercial plants (common bean, komatsuna, Qing geng cai, bell pepper, kale, and lettuce. PSAE were measured for total phenolic content (TPC with the Folin-Ciocalteu method, and the 2-diphenyl-1-picryl-hydrazyl (DPPH radical scavenging effect of each seed extract was measured. To find a protectant against Aβ-induced oxidative stress, we screened 15 PSAE using a 2′, 7′-dichlorofluorescein diacetate assay. To further unravel the anti-inflammatory effects of PSAE on Aβ-induced inflammation, PSAE were added to HIPN. The neuroprotective effects of the PSAE were evaluated by Cell Counting Kit-8 assay, measuring the cell viability in Aβ-induced HIPN. Results: TPC of 15 PSAE was in the range of 0.024-1.96 mg of chlorogenic acid equivalents/gram. The aqueous extracts showed antioxidant activities. Furthermore, intracellular ROS accumulation resulting from Aβ treatment was reduced when cells were treated with some PSAE. Kale, bitter melon, kaiware radish, red shiso, and corn inhibited tumor necrosis factor-alpha secretion by the Aβ-stimulated neurons and all samples except Japanese honeywort showed enhancement of cell survival. Conclusion: From these results, we suggest that some plant seed extracts offer protection against Aβ-mediated cell death.

The G-tetrad-forming oligonucleotides and have been identified as potent inhibitors of human immunodeficiency virus type 1 integrase (HIV-1 IN) activity (Rando, R. F., Ojwang, J., Elbaggari, A., Reyes, G. R., Tinder, R., McGrath, M. S., and Hogan, M. E. (1995) J. Biol. Chem. 270, 1754-1760; Mazumder, A., Neamati, N., Ojwang, J. O., Sunder, S., Rando, R.

To understand the inhibition of HIV-1 IN activity by the G-quartet inhibitors, we have designed the oligonucleotides and, composed of three and four G-quartets with stem lengths of 19 and 24 A, respectively. The fact that increasing the G-quartet stem length from 15 to 24 A kept inhibition of HIV-1 IN activity unchanged suggests that the binding interaction occurs between a GTGT loop domain of the G-quartet inhibitors and a catalytic site of HIV-1 IN, referred to as a face-to-face interaction. Docking the NMR structure of (Jing and Hogan (1998)) into the x-ray structure of the core domain of HIV-1 IN, HIV-1 IN-(51-209) (Maignan, S., Guilloteau, J.-P. , Qing, Z.-L., Clement-Mella, C., and Mikol, V. (1998) J. Mol. Biol. 282, 359-368), was performed using the GRAMM program. The statistical distributions of hydrogen bonding between HIV-1 IN and were obtained from the analyses of 1000 random docking structures. The docking results show a high probability of interaction between the GTGT loop residues of the G-quartet inhibitors and the catalytic site of HIV-1 IN, in agreement with the experimental observation.

This study aimed to use spatiotemporal PET imaging to investigate the dynamic metabolic changes after a combined therapeutic approach of induced pluripotent stem cells (iPSCs), neuronal stem cells (NSCs), and Chinese patent medicine in a rat model of cerebral ischemia-reperfusion injury. Cerebral ischemia was established by the middle cerebral artery occlusion approach. Thirty-six male rats were randomly assigned to 1 of the 6 groups: control phosphate-buffered saline (PBS), Chinese patent medicine (Qing-kai-ling [QKL]), induced pluripotent stem cells (iPSCs), combination of iPSCs and QKL, neuronal stem cells (NSCs), and combination of NSCs and QKL. Serial (18)F-FDG small-animal PET imaging and neurofunctional tests were performed weekly. Autoradiographic imaging and immunohistochemical and immunofluorescent analyses were performed at 4 wk after stem cell transplantation. Compared with the PBS control group, significantly higher (18)F-FDG accumulations in the ipsilateral cerebral infarction were observed in 5 treatment groups from weeks 1-4. Interestingly, the most intensive (18)F-FDG accumulation was found in the NSCs + QKL group at week 1 but in the iPSCs + QKL group at week 4. The neurofunctional scores in the 5 treatment groups were significantly higher than that of the PBS group from week 3 to 4. In addition, there was a significant correlation between the PET imaging findings and neurofunctional recovery (P PET imaging with (18)F-FDG demonstrated dynamic metabolic and functional recovery after iPSCs or NSCs combined with QKL in a rat model of cerebral ischemia-reperfusion injury. iPSCs or NSCs combined with Chinese medicine QKL seemed to be a better therapeutic approach than these stem cells used individually. © 2015 by the Society of Nuclear Medicine and Molecular Imaging, Inc.

Glyphosate and its degradation product, aminomethylphosphonic acid (AMPA, are analogs to glycine, thus they may inhibit serine hydroxymethyltransferase to decrease intracellular glycine synthesis. In this study, we found that glyphosate and AMPA inhibited cell growth in eight human cancer cell lines but not in two immortalized human normal prostatic epithelial cell lines. AMPA arrested C4-2B and PC-3 cancer cells in the G1/G0 phase and inhibited entry into the S phase of the cell cycle. AMPA also promoted apoptosis in C4-2B and PC-3 cancer cell lines. AMPA upregulated p53 and p21 protein levels as well as procaspase 9 protein levels in C4-2B cells, whereas it downregulated cyclin D3 protein levels. AMPA also activated caspase 3 and induced cleavage of poly (adenosine diphosphate [ADP]-ribose polymerase. This study provides the first evidence that glyphosate and AMPA can inhibit proliferation and promote apoptosis of cancer cells but not normal cells, suggesting that they have potentials to be developed into a new anticancer therapy.

CONSTITUTIONAL TRANSPLANT IN THE PEOPLE’S REPUBLIC OF CHINA: THE INFLUENCE OF THE SOVIET MODEL AND CHALLENGES IN THE GLOBALIZATION ERA

2015-01-01

Full Text Available In this essay, I mainly focus on the constitutional transplantation in the People’s Republic of China. Firstly, I briefly present the Chinese constitution-making process from the Qing dynasty to the Republic of China to show that both regimes had transplanted more or less liberal constitutional principles, rules and institutions into their domestic constitutional document. Then, because China and the Former Soviet Union shared the Marxism-Leninism, China’s 1954 Constitution borrowed almost all the constitutional articles to various extents from the 1936 Soviet constitutional code. Though few articles of the 1977 Soviet Constitution have been imported into China’s present 1982 Constitution, China’s Constitution is still influenced by the Soviet model of constitution in many aspects related to the political and legal reform in the post-Mao era. Globalization brings many challenges to present-day China’s Soviet- featured constitutional system. With China’s accession to the WTO, a qualified judicial review mechanism is required to be established by the other Member States. However, China seems not to satisfy this obligation under the framework of the present legal system. In addition, a constitutional review mechanism is still absent in China. Besides, the modern Chinese legal system keeps silent on the domestic implementation of the UN international human rights treaties in view of the fact that Chinese international law theory was molded by Soviet’s which took highly concerned on protection of its state sovereignty. Chinese authorities, on the other hand, take a vague attitude to universal human rights standards. They sometimes prefer to observe them, while in other cases, they are not willing to follow them. Besides that, the domestic effects of international law also depend on the outcomes of the struggle and compromise between the reformist and Chinese Marxist conservative.

Full Text Available Background/Aims: Qing Dai is a prized traditional Chinese medicine whose major component, indirubin, and its derivative, indirubin-3’-monoxime (IDM, have inhibitory effects on the growth of many human tumor cells and pronounced anti-leukemic activities. However, the effects of IDM on mature human erythrocytes are unclear. This study aimed to evaluate the potential impact of IDM on erythrocytes and the mechanisms underlying that impact. Methods: Utilizing flow cytometry and confocal laser scanning microscopy, phosphatidylserine exposure at the cell surface was estimated by annexin V-fluorescein isothiocyanate (FITC. The relative cell size, expressed in arbitrary units, was evaluated by forward scatter in a flow cytometer. Fluo-3 fluorescence was used to bewrite changes in cytosolic Ca2+ activity, reactive oxygen species (ROS formation was assessed by 2,7-dichlorodihydrofluorescein diacetate (DCFH-DA fluorescence, and ceramide abundance was evaluated by FITC-conjugated specific antibodies. Results: The 24-h exposure of human erythrocytes to IDM (12 µM significantly decreased the percentage of annexin V-binding erythrocytes and the intracellular calcium concentration ([Ca2+]i. IDM (3-12 µM did not significantly modify the ceramide level or DCFH-DA fluorescence. Energy depletion (removal of glucose for 24 hours significantly increased annexin V binding and Fluo-3 fluorescence and diminished forward scatter, and these effects were significantly mitigated by IDM (12 µM. Moreover, the Ca2+ ionophore ionomycin (1 µM, 60 min and oxidative stress (30 min exposure to 0.05 mM tert-butyl hydroperoxide, t-BHP similarly triggered eryptosis, which was also significantly suppressed by IDM. Conclusions: IDM is a novel inhibitor of suicidal erythrocyte death following ionomycin treatment, t-BHP treatment and energy depletion. Thus, IDM may counteract anemia and impairment of microcirculation, at least in part, by inhibition of Ca2+ entry into erythrocytes.

Three types of MWCNTs – VGCF®-X, VGCF®-S, and VGCF® (vapor grown carbon fibers; with diameters of 15, 80, and 150 nm, respectively – and three CSCNTs of different lengths (CS-L, 20–80 µm; CS-S, 0.5–20 µm; and CS-M, of intermediate length were tested. Human bronchial epithelial (BEAS-2B and malignant pleural mesothelioma cells were exposed to the CNTs (1–50 µg/mL, and cell viability, permeability, uptake, total reactive oxygen species/superoxide production, and intracellular acidity were measured. CSCNTs were less toxic than MWCNTs in both cell types over a 24-hour exposure period. The cytotoxicity of endocytosed MWCNTs varied according to cell type/size, while that of CSCNTs depended on tube length irrespective of cell type. CNT diameter and length influenced cell aggregation and injury extent. Intracellular acidity increased independently of lysosomal activity along with the number of vacuoles in BEAS-2B cells exposed for 24 hours to either CNT

As yokukan-san has become broadly integrated with conventional medicine, augmentation therapy with other Kampo prescriptions has become necessary when the yokukan-san has been only partially efficacious. In this paper, we report three cases in which the addition of orengedoku-to, another Kampo formula, to yokukan-san was remarkably effective.Cases: Case 1 was an 85-year-old man with Alzheimer-type dementia who had become aggressive during the past 2 years. Three milligrams of aripiprazole completely suppressed his problematic behaviors but had to be stopped because of extrapyramidal symptoms. In the second case, a 44-year-old man with methamphetamine-induced psychosis had suffered from serious tardive dystonia for 2 years. No conventional approach had improved his tardive dystonia. The third case was a 29-year-old engineer who often failed to resist aggressive impulses and was diagnosed with intermittent explosive disorder. He was prescribed 5 mg of olanzapine, which did not suppress his extraordinary anger and caused somnolence even though the dose was low.Interventions and outcomes: Yokukan-san was complementarily added to the patients' regular medication and exerted a definitive but partial effect in all cases. The addition of orengedoku-to to yokukan-san exerted the same efficacy as aripiprazole in controlling aggressiveness in Case 1

Acceleration training (AT is a new training method that provides a physical stimulation effect on skeletal muscles by increasing gravitational acceleration with vibration. AT has recently been indicated as a component of medicine. In this study, we evaluated the effectiveness of AT in the management of NAFLD in obese subjects.Methods: A total of 18 obese patients with NAFLD who had no improvement in liver function test abnormalities and/or steatosis grade after 12 weeks of lifestyle counseling were enrolled in an AT program. These patients attended a 20-minute session of AT twice a week for 12 consecutive weeks.Results: During the AT program, the NAFLD patients showed a modest increase in the strength (+12.6% and cross-sectional area (+3.1% of the quadriceps, coupled with a significant reduction in intramyocellular lipids (−26.4%. Notably, they showed a modest reduction in body weight (−1.9%, abdominal visceral fat area (−3.4%, and hepatic fat content (−8.7%, coupled with a significant reduction in levels of aminotransferase (−15.7%, γ-glutamyltransferase (−14.4%, leptin (−9.7%, interleukin-6 (−26.8%, and tumor necrosis factor-α (−17.9%, and a significant increase of adiponectin (+8.7%.

The current study assessed attitudes toward metabolic adverse events among patients with schizophrenia. Methods: A brief questionnaire was constructed to investigate patient recognition of the following broad areas: dietary habits, lifestyle, self-monitoring, knowledge, and medical practice. Between January 2012 and June 2013, questionnaires were sent to patients associated with 520 outpatient facilities and 247 inpatient facilities belonging to the Japan Psychiatric Hospital Association. All of the participants (n=22,072; inpatients =15,170, outpatients =6,902 were diagnosed with schizophrenia based on the Diagnostic and Statistical Manual of Mental Disorders, fourth edition, or the International Classification of Diseases, tenth revision. Results: Approximately 55.0% (8,069/14,669 of inpatients and 44.8% of outpatients (2,978/6,649 reported that they did not exercise at all.
