2Characteristics of Obesity and Its Related Disorders in China显示文摘Obesity is a medical condition with excess body fat accumulation to the extent which leads to serious health consequences.Abdominal obesity,also known as central obesity,refers to the presence of excess fat in the abdominal area.Obesity,especially abdominal obesity,contributes to many metabolic disorders including metabolic syndrome (MetS),type 2 diabetes (T2DM) and cardiovascular diseases (CVD).The incidence of obesity has increased dramatically in recent years worldwide.In China,more than one-third of adults are overweight or obese and 10%-20% of all adults are affected by MetS.The pathogenesis underlying the abdominal obesity remains unclear.The ultimate health outcome of obesity and its related metabolic disorders have prompted physicians to take aggressive treatments (lifestyle changes,pharmacological interventions and surgical therapies) before a serious consequence becomes clinically apparent.In this review,we discuss the prevalence,pathogenesis and clinic features of obesity in China.WEI-PING JIA ,CHEN WANG,SHAN JIANG,AND JIE-MIN PAN Department of Endocrinology and Metabolism,Shanghai Jiao Tong University Affiliated Sixth People’s Hospital,Shanghai Diabetes Institute,Shanghai Clinical Center of Diabetes,Shanghai 200233,China 2010Biomedical and Environmental Sciences2010,23,1:46

4Quantitative analysis of hepatic hypoxia-inducible factor-1α and its abnormal gene expression during the formation of hepatocellular carcinoma显示文摘BACKGROUND:Hepatic hypoxia-inducible factor-1(HIF-1) is activated in the progression of hepatocellular carcinoma (HCC).This study aimed to investigate the dynamic alterations of HIF-1αand its gene expression so as to explore the relationship between HIF-1αexpression and hepatocarcinogenesis at the early stage of HCC. METHODS:A hepatoma model was made with 2-fluorenyl- acetamide(2-FAA)in male Sprague-Dawley rats.Morphological changes of rat hepatocytes were assessed pathologically (HE staining).The dynamic expression of hepatic and circulating HIF-1αwas quantitatively analyzed by ELISA. The gene fragments of hepatic HIF-1αmRNA were amplified by RT-PCR and confirmed by sequencing.The cellular distribution of hepatic HIF-1αexpression was confirmed by immunohistochemistry. RESULTS:Histological examination confirmed granulelike degeneration to atypical hyperplasia and HCC development in rat hepatocytes and progressive increases in the levels of hepatic and circulating HIF-1αand its gene expression during the course.The levels of HIF-1α expression in the liver and blood of rats with hepatoma were significantly higher than those in normal ratsand those with degeneration.Immunohistochemical analysis confirmed the positive expression and hepatocyte distribution of HIF-1αin the development of rat hepatoma. A positive relationship was found between HIF-1α expression in the liver and blood(P<0.01). CONCLUSIONS:The above observations support the hypothesis that the overexpression of HIF-1αand its gene are closely associated with the malignant transformation of hepatocytes and play an important role at the stage of hepatocarcinogenesis.Deng-Fu Yao,Hua Jiang,Min Yao,Yue-Ming Li,Wen-Jing Gu,Yu-Cheng Shen, Li-Wei Qiu,Wei Wu,Xin-Hua Wu and Wen-Li Sai Research Center of Clinical Molecular Biology,Department of Laboratory Science,and Department of Oncology,Affiliated Hospital of Nantong University,Nantong 226001, China Third Department of Medicine,Jiaonan People’s Hospital,Jiaonan 266400,China 2009Hepatobiliary & Pancreatic Diseases International2009,8,4:28

6Interleukin-33 drives hepatic fibrosis through activation of hepatic stellate cells显示文摘Liver fibrosis is a consequence of chronic liver disease,causing morbidity and mortality.Interleukin-33(IL-33)is a critical mediator of inflammation,which may be involved in the development of liver fibrosis.Here,we investigated the role of IL-33 in human patients and experimental bile-duct ligation(BDL)-induced fibrosis in mice.We report increased hepatic IL-33 expression in the murine BDL model of fibrosis and in surgical samples obtained from patients with liver fibrosis.Liver injury,inflammatory cell infiltration and fibrosis were reduced in the absence of the IL-33/ST2 receptor,and the activation of hepatic stellate cells(HSCs)was decreased in ST2-deficient mice.Recombinant IL-33 activated HSCs isolated from C57BL/6 mice,leading to the expression of IL-6,TGF-β,α-SMA and collagen,which was abrogated in the absence of ST2 or by pharmacological inhibition of MAPK signaling.Finally,administration of recombinant IL-33 significantly increased hepatic inflammation in sham-operated BL6 mice but did not enhance BDL-induced hepatic inflammation and fibrosis.In conclusion,BDL-induced liver inflammation and fibrosis are dependent on ST2 signaling in HSCs,and therefore,the IL-33/ST2 pathway may be a potential therapeutic target in human patients with chronic hepatitis and liver fibrosis.Zhongming Tan Qianghui Liu Runqiu Jiang Long Lv Siamak S Shoto Isabelle Maillet Valerie Quesniaux Junwei Tang Wenjie Zhang Beicheng Sun Bernhard Ryffel 2018Cellular & Molecular Immunology2018,15,4:24

11Research progress and strategies for multifunctional rapeseed: A case study of China显示文摘Rapeseed(Brassicanapus),is an important source of edible oil,animal fodder,vegetables,condiments and biodiesel,and plays a significant role in securing edible oil production worldwide.However,in countries with comparatively low levels of agricultural mechanization,such as China,increasing costs of labor and agricultural inputs are decreasing rapeseed profitability,and hence the area of rapeseed under cultivation.If the value of rapeseed crops is not further increased,the rapeseed growing area will continue to decrease,potentially jeopardizing oil production.Therefore,full exploitation of the existing and potential value of rapeseed is desirable.Different rapeseed products are already utilized in different ways,with more applications currently underutilized.As well as oil extraction from the seeds,the shoot and leaves can be used as vegetables,the roots to absorb soil cadmium for pollution remediation,the flowers for sightseeing and as a source of nectar,the pollen for extracting flavonoids and useful amino acids,the seeds/seed meal for extracting isthiocyanates and other important sulforaphane compounds,the straw and seed meal for fodder,and immature whole plants for green manure.This review summarizes recent research on ways to explore the potential holistic value of rapeseed,by taking the example of multifunctionality of rapeseed in China.FU Dong-hui JIANG Ling-yan Annaliese S Mason XIAO Mei-li ZHU Long-rong LI Li-zhi ZHOU Qing-hong SHEN Chang-jian HUANG Chun-hui 2016Journal of Integrative Agriculture2016,15,8:15
12Enteral nutrition in treatment of severe acute pancreatitis显示文摘Objective: To observe the role and the timing of EN inthe treatment of patients with severe acute pancreatitis(SAP).Methods: Eleven patients with severe acute pancreatitisunderwent systemic nutrition support were studied.EN was given through jejunostomy tube (or Beng-mark tube) after a period of PN maintenance. ENstarted when serum and urine amylase activity re-turned to normal with regular peristaltic sound, defe-cation or break wind. The sequence of preparationwas as follows: saline glucose→chemically defined di-et→polymeric diet→normal diet.Results: In all the patients, none died. The rate of latecomplications was lower, and the levels of serum albu-min and transferritin significantly increased in thepost-EN period as compared with the pre-EN period,although the count of lymphocytes was less changed.Conclusions: Nutritional support should be trans-formed from PN to EN as early as possible during thetreatment of patients with severe acute pancreatitis. ENcould not only continue sufficient nutritional support,but also avoid the unfavorable effects of long-timePN, thus reducing complications as well as mortality.Dun Shi Cheng-Wu Zhang Jin-Song Jiang Zhi-Jie Xie Shou-Chun Zou From the Department of General Surgery, Zhejiang Provincial People’s Hospital, Hangzhou 310014, China 2002Hepatobiliary & Pancreatic Diseases International2002,1,1:14

14Overexpression of an ABA biosynthesis gene using a stress-inducible promoter enhances drought resistance in petunia显示文摘The response of plants to drought stress includes reduced transpiration as stomates close in response to increased abscisic acid(ABA)concentrations.Constitutive overexpression of 9-cis-epoxycarotenoid dioxygenase(NCED),a key enzyme in ABA biosynthesis,increases drought resistance,but causes negative pleiotropic effects on plant growth and development.We overexpressed the tomato NCED(LeNCED1)in petunia plants under the control of a stress-inducible promoter,rd29A.Under water stress,the transgenic plants had increased transcripts of NCED mRNA,elevated leaf ABA concentrations,increased concentrations of proline,and a significant increase in drought resistance.The transgenic plants also displayed the expected decreases in stomatal conductance,transpiration,and photosynthesis.After 14 days without water,the control plants were dead,but the transgenic plants,though wilted,recovered fully when re-watered.Well-watered transgenic plants grew like non-transformed control plants and there was no effect of the transgene on seed dormancy.Alejandro C Estrada-Melo Chao Ma Michael S Reid Cai-Zhong Jiang 2015Horticulture Research2015,2,1:12
15The enhanced X-ray Timing and Polarimetry mission—eXTP显示文摘In this paper we present the enhanced X-ray Timing and Polarimetry mission—eXTP. eXTP is a space science mission designed to study fundamental physics under extreme conditions of density, gravity and magnetism. The mission aims at determining the equation of state of matter at supra-nuclear density, measuring effects of QED, and understanding the dynamics of matter in strong-field gravity. In addition to investigating fundamental physics, eXTP will be a very powerful observatory for astrophysics that will provide observations of unprecedented quality on a variety of galactic and extragalactic objects. In particular, its wide field monitoring capabilities will be highly instrumental to detect the electro-magnetic counterparts of gravitational wave sources.The paper provides a detailed description of:(1) the technological and technical aspects, and the expected performance of the instruments of the scientific payload;(2) the elements and functions of the mission, from the spacecraft to the ground segment.ShuangNan Zhang Andrea Santangelo Marco Feroci YuPeng Xu FangJun Lu Yong Chen Hua Feng Shu Zhang Sφren Brandt Margarita Hernanz Luca Baldini Enrico Bozzo Riccardo Campana Alessandra De Rosa YongWei Dong Yuri Evangelista Vladimir Karas Norbert Meidinger Aline Meuris Kirpal Nandra Teng Pan Giovanni Pareschi Piotr Orleanski QiuShi Huang Stephane Schanne Giorgia Sironi Daniele Spiga Jiri Svoboda Gianpiero Tagliaferri Christoph Tenzer Andrea Vacchi Silvia Zane Dave Walton ZhanShan Wang Berend Winter Xin Wu Jean J.M.in't Zand Mahdi Ahangarianabhari Giovanni Ambrosi Filippo Ambrosino Marco Barbera Stefano Basso Jörg Bayer Ronaldo Bellazzini Pierluigi Bellutti Bruna Bertucci Giuseppe Bertuccio Giacomo Borghi XueLei Cao Franck Cadoux Francesco Ceraudo TianXiang Chen Yu Peng Chen Jerome Chevenez Marta Civitani Wei Cui WeiWei Cui Thomas Dauser Ettore Del Monte Sergio Di Cosimo Sebastian Diebold Victor Doroshenko Michal Dovciak YuanYuan Du Lorenzo Ducci QingMei Fan Yannick Favre Fabio Fuschino JoséLuis Ga'lvez Min Gao MingYu Ge Olivier Gevin Marco Grassi QuanYing Gu YuDong Gu DaWei Han Bin Hong Wei Hu Long Ji ShuMei Jia WeiChun Jiang Thomas Kennedy Ingo Kreykenbohm Irfan Kuvvetli Claudio Labanti Luca Latronico Gang Li MaoShun Li Xian Li Wei Li ZhengWei Li Olivier Limousin HongWei Liu XiaoJing Liu Bo Lu Tao Luo Daniele Macera Piero Malcovati Adrian Martindale Malgorzata Michalska Bin Meng Massimo Minuti Alfredo Morbidini Fabio Muleri Stephane Paltani Emanuele Perinati Antonino Picciotto Claudio Piemonte JinLu Qu Alexandre Rachevski Irina Rashevskaya Jerome Rodriguez Thomas Schanz ZhengXiang Shen LiZhi Sheng JiangBo Song LiMing Song Carmelo Sgro Liang Sun Ying Tan Phil Uttley Bo Wang DianLong Wang GuoFeng Wang Juan Wang LangPing Wang YuSa Wang Anna L.Watts XiangYang Wen Jörn Wilms ShaoLin Xiong JiaWei Yang Sheng Yang YanJi Yang Nian Yu WenDa Zhang Gianluigi Zampa Nicola Zampa Andrzej A.Zdziarski AiMei Zhang ChengMo Zhang Fan Zhang Long Zhang Tong Zhang Yi Zhang XiaoLi Zhang ZiLiang Zhang BaoSheng Zhao ShiJie Zheng Yu Peng Zhou Nicola Zorzi J.Frans Zwart 2019Science China(Physics,Mechanics & Astronomy)2019,62,2:11
16Protective effects of Ligustrazine,Kakonein and Panax Notoginsenoside on the small intestine and immune organs of rats with severe acute pancreatitis显示文摘BACKGROUND:Severe acute pancreatitis (SAP) is characterized by fatal pathogenic conditions and a high mortality.It is important to study SAP complicated with multiple organ injury.In this study we compared the protective effects of three traditional Chinese medicines (Ligustrazine,Kakonein and Panax Notoginsenoside) on the small intestine and immune organs (thymus,spleen and lymph nodes) of rats with SAP and explored their mechanism of action.METHODS:One hundred forty-four rats with SAP were randomly divided into model control,Ligustrazine-treated,Kakonein-treated,and Panax Notoginsenoside-treated groups (n=36 per group).Another 36 normal rats comprised the sham-operated group.According to the different time points after operation,the experimental rats in each group were subdivided into 3-,6-and 12-hour subgroups (n=12).At various time points after operation,the mortality rate of rats and pathological changes in the small intestine and immune organs were recorded and the serum amylase levels were measured.RESULTS:Compared to the model control groups,the mortality rates in all treated groups declined and the pathological changes in the small intestine and immune tissues were relieved to different degrees.The serum amylase levels in the three treated groups were significantly lower than those in the model control group at 12 hours.The pathological severity scores for the small intestinal mucosa,thymus and spleen (at 3 and 12 hours) in the Ligustrazine-treated group,for the thymus (at 3 and 12 hours) and spleen (at 3 and 6 hours) in the Kakonein-treated group,and for the thymus (at 3 hours)and spleen (at 3 hours) in the Panax Notoginsenoside-treated group were significantly lower than those in the model control group.The pathological severity scores of the small intestinal mucosa (at 6 and 12 hours) and thymus (at 6 hours) in the Ligustrazine-treated group were significantly lower than those in the Kakonein-and Panax Notoginsenoside-treated groups.CONCLUSIONS:All the three traditional Chinese drugs significantly alleviated the pathological changes in the small intestine and immune organs of SAP rats.Ligustrazine was the most effective one among them.Xi-Ping Zhang,Jun Jiang,Qi-Hui Cheng,Qian Ye,Wei-Juan Li,Hua Zhu and Jun-Ya Shen Department of General Surgery,Department of Gynecology and Obstetrics and Central Laboratory Department,Hangzhou First People’s Hospital,Hangzhou 310006,China Zhejiang Chinese Medical University,Hangzhou 310053,China 2011Hepatobiliary & Pancreatic Diseases International2011,10,6:11

19Spontaneous viral clearance after 6-21 years of hepatitis B and C viruses coinfection in high HBV endemic area显示文摘AIM: To investigate the clinical and virological course of coinfection by hepatitis B virus (HBV) and hepatitis C virus (HCV) in China.METHODS: We enrolled 40 patients with chronic HBV and HCV coinfection (Group BC), 16 patients with chronic HBV infection (Group B) and 31 patients with chronic HCV infection (Group C). They infected HBV and/or HCV during 1982 to 1989.Sera of all the 87 patients were collected in 1994 and 2002respectively. We detected biochemical and virologic markers and serum HBV DNA and HCV RNA levels of all the patients. Btype ultrasound detection was performed in some patients.RESULTS: In Group BC, 67.5% of the patients cleared HBsAg,and 92.5% of the patients cleared HBeAg. The clearance rate of HBV DNA was 87.5%. There was no significant difference of HBV clearance between Group BC and Group B. In Group BC, 85.7% of males and 47.4% of females cleared HBV, and males were easier to clear HBV (x2=6.686, P=0.010). Such a tendency was also found in Group B. The clearance rate of HCV RNA in Group BC was 87.5%, significantly higher than that in Group C (x2=22.963, P<0.001). Less than 40% of the patients in all groups had elevated liver enzyme values. The highest value of alanine aminotransferase (ALT) was 218 u/L (normal range for ALT is 0-40 u/L). In most patients the ultrasonogram presentations changed mildly.CONCLUSION: The clinical manifestations of patients with HBV/HCV coinfection are mild and occult. High clearance rate of HBV and easy to clear HBV in male patients are the characteristics of HBV infection in adults in China. HBV can inhibit HCV replication, but no evidence has been found in our data that HCV suppresses HBV replication.Chun-Lei Fan Lai Wei Dong Jiang Hong-Song Chen Yan Gao Ruo-Bing Li Yu Wang Institute of Hepatology,People’s Hospital,Peking University,Beijing 100044,China 2003World Journal of Gastroenterology2003,9,9:10
