1Differing coping mechanisms, stress level and anorectal physiology in patients with functional constipation显示文摘AIM: To investigate coping mechanisms, constipation symptoms and anorectal physiology in 80 constipated subjects and 18 controls.METHODS: Constipation was diagnosed by Rome Ⅱ criteria.Coping ability and anxiety/depression were assessed by validated questionnaires. Transit time and balloon distension test were performed.RESULTS: 34.5% patients were classified as slow transit type of constipation. The total colonic transit time (56 h vs 10 h, P<0.0001) and rectal sensation including urge sensation (79 mL vs 63 mL, P = 0.019) and maximum tolerable volume (110 mL vs95 mL, P = 0.03) differed in patients and controls. Constipated subjects had significantly higher anxiety and depression scores and lower SF-36 scores in all categories. They also demonstrated higher scores of'monitoring' coping strategy (14+6 vs9+3, P = 0.001),which correlated with the rectal distension sensation (P = 0.005), urge sensation (P=0.002), and maximum tolerable volume (P = 0.035). The less use of blunting strategy predicted slow transit constipation in both univariate (P = 0.01) and multivariate analysis (P = 0.03).CONCLUSION: Defective or ineffective use of coping strategies may be an important etiology in functional constipation and subsequently reflected in abnormal anorectal physiology.Annie OO Chan Cecilia Cheng Wai Mo Hui Wayne HC Hu Nina YH Wong KF Lam Wai Man Wong Kam Chuen Lai Shiu Kum Lam Benjamin CY Wong 2005World Journal of Gastroenterology2005,11,34:92
2Outline of the Report on Cardiovascular Disease in China,2010显示文摘Major and profound changes have taken place in China over the past 30 years.Rapid socioeconomic progress has exerted a great impact on lifestyle,ranging from food,clothing,working and living conditions,and means of transportation to leisure activities and entertainment.At the same time,new health problems have emerged,and health services are facing new challenges.Presently,cardiovascular diseases (CVD) are among the top health problems of the Chinese people,and pose a serious challenge to all engaged in the prevention and control of these diseases.An epidemic of CVD in China is emerging as a result of lifestyle changes,urbanization and longevity.Both national policy decision-making and medical practice urgently need an authoritative report which comprehensively reflects the trends in the epidemic of CVD and current preventive measures.Since 2005,guided by the Bureau of Disease Prevention of the Ministry of Health of the People's Republic of China and the National Center for Cardiovascular Diseases of China,nationwide experts in the fields of epidemiology,clinical medicine and health economics in the realms of CVD,cerebrovascular disease,diabetes and chronic kidney disease,completed the Report on Cardiovascular Diseases in China every year.The report aims to provide a timely review of the trend of the epidemic and to assess the progress of prevention and control of CVD.In addition,as the report is authoritative,representative and readable,it will become an information platform in the CVD field and an important reference book for government,academic institutes,medical organizations and clinical physicians.This publication is expected to play a positive role in the prevention and control of CVD in China.We present an abstract from the Report on Cardiovascular Diseases in China (2010),including trends in CVD,morbidity and mortality of major CVDs,up-to-date assessment of risk factors,as well as health resources for CVD,and a profile of medical expenditure,with the aim of providing evidence for decision-making in CVD prevention and control programs in China,and of delivering the most authoritative information on CVD prevention and control for all citizens.HUSheng Shou KONG Ling Zhi GAO Run Lin ZHU Man Lu WANG Wen WANG Yong Jun WU Zhao Su CHEN Wei Wei LIU Ming Bo For the editorial board 2012Biomedical and Environmental Sciences2012,25,3:93
3Anthropogenic emission inventories in China:a review显示文摘The development of reliable anthropogenic emission inventories is essential for both understanding the sources of air pollution and designing effective air-pollution-control measures in China. However, it is challenging to quantify emissions in China accurately, given the variety of contributing sources, the complexity of the technology mix and the lack of reliable measurements. Over the last two decades,tremendous efforts have been made to improve the accuracy of emission inventories, and significant improvements have been realized. More reliable statistics and survey-based data have been used to reduce the uncertainties in activity rates and technology distributions. Local emission factors and source profiles covering various sources have been measured and reported. Based on these local databases, improved emission inventory models have been developed for power plants, large industrial plants and the residential,transportation and agricultural sectors. In this paper, we review the progress that has been made in developing inventories of anthropogenic emissions in China. We first highlight the major updates that have been made to emission inventory models and the underlying data by source category. We then summarize the sector-based estimates of emissions of different species contained in current inventories. The progress that has been made in the development of model-ready emissions is also presented. Finally, we suggest future directions for further improving the accuracy of emission inventories in China.Meng Li Huan Liu Guannan Geng Chaopeng Hong Fei Liu Yu Song Dan Tong Bo Zheng Hongyang Cui Hanyang Man Qiang Zhang Kebin He 2017National Science Review2017,4,6:100
4A complete sequence and comparative analysis of a SARS-associated virus(Isolate BJ01)显示文摘The genome sequence of the Severe Acute Respiratory Syndrome (SARS)-associated virus provides essential information for the identification of pathogen(s), exploration of etiology and evolution, interpretation of transmission and pathogenesis, development of diagnostics, prevention by future vaccination, and treatment by developing new drugs. We report the complete genome sequence and comparative analysis of an isolate (BJ01) of the coronavirus that has been recognized as a pathogen for SARS. The genome is 29725 nt in size and has 11 ORFs (Open Reading Frames). It is composed of a stable region encoding an RNA-dependent RNA polymerase (composed of 2 ORFs) and a variable region representing 4 CDSs (coding sequences) for viral structural genes (the S, E, M, N proteins) and 5 PUPs (putative uncharacterized proteins). Its gene order is identical to that of other known coronaviruses. The sequence alignment with all known RNA viruses places this virus as a member in the family of Coronaviridae. Thirty putative substitutions have been identified by comparative analysis of the 5 SARS- associated virus genome sequences in GenBank. Fifteen of them lead to possible amino acid changes (non-synonymous mutations) in the proteins. Three amino acid changes, with predicted alteration of physical and chemical features, have been detected in the S protein that is postulated to beinvolved in the immunoreactions between the virus and its host. Two amino acid changes have been detected in the Mprotein, which could be related to viral envelope formation. Phylogenetic analysis suggests the possibility of non-human origin of the SARS-associated viruses but provides noevidence that they are man-made. Further efforts should focus on identifying the etiology of the SARS-associated virus and ruling out conclusively the existence of otherpossible SARS-related pathogen(s).QIN E'de ZHU Qingyu YU Man FAN Baochang CHANG Guohui SI Bingyin YANG Bao PENG Wenming JIANG Tao LIU Bohua DENG Yongqiang LIU Hong ZHANG Yu WANG Cui LI Yuquan GAN Yonghua LI Xiaoyu L Fushuang TAN Gang CAO Wuchun, YANG Ruifu Institute of Microbiology and Epidemiology, Chinese Academy of Military Medical Sciences, Beijing 100071, China WANG Jian, LI Wei, XU Zuyuan, LI Yan, WU Qingfa, LIN Wei, CHEN Weijun, TANG Lin, DENG Yajun, HAN Yujun, LI Changfeng, LEI Meng, LI Guoqing, LI Wenjie, L Hong, SHI Jianping, TONG Zongzhong, ZHANG Feng, LI Songgang, LIU Bin, LIU Siqi, DONG Wei, WANG Jun, Gane K-S Wong, YU Jun & YANG Huanming* Beijing Genomics Institute, Chinese Academy of Sciences, Beijing 101300 National Center for Genome Information, Beijing 101300, China 2003Chinese Science Bulletin2003,48,10:121
5Dual Functions of Microglia in Ischemic Stroke显示文摘Ischemic stroke is a leading cause of morbidity and mortality worldwide. Resident microglia are the principal immune cells of the brain, and the first to respond to the pathophysiological changes induced by ischemic stroke. Traditionally, it has been thought that microglial activation is deleterious in ischemic stroke, and therapies to suppress it have been intensively explored. However,increasing evidence suggests that microglial activation is also critical for neurogenesis, angiogenesis, and synaptic remodeling, thereby promoting functional recovery after cerebral ischemia. Here, we comprehensively review the dual role of microglia during the different phases of ischemic stroke, and the possible mechanisms controlling the post-ischemic activity of microglia. In addition, we discuss the dynamic interactions between microglia and other cells, such as neurons, astrocytes, oligodendrocytes,and endothelial cells within the brain parenchyma and the neurovascular unit.Chuan Qin Luo-Qi Zhou Xiao-Tong Ma Zi-Wei Hu Sheng Yang Man Chen Dale B.

6Immune mechanisms of Concanavalin A model of autoimmune hepatitis显示文摘As a chronic inflammatory disease of the liver,the pathogenic mechanisms of autoimmune hepatitis (AIH) have not yet been elucidated,with prognosis and diagnosis remaining unsatisfied.Currently the only viable treatments of AIH are immunosuppressant application and liver transplantation.It is considered that lack of good animal AIH models is the main reason for the shortage of a simple and efficient cure.The Concanavalin A (Con A) model is a typical and well established model for investigating T-cell and macrophage dependent liver injury in mice,which closely mimics the pathogenesis mechanisms and pathological changes of patients,and is regarded as the best experimental model for AIH research so far.In this paper we eluci-dated the pathogenic mechanisms of AIH and the evolution of relative animal models.We go on to further focus on Con A-induced liver injury from the point of immunological mechanisms and the change of cytokine levels.Finally,we manifested the clinical significance of the AIH animal models and the challenges they would meet during their future development.Hai-Xia Wang Man Liu Shun-Yan Weng Jing-Jing Li Chao Xie Hong-Lin He Wen Guan Yun-Sheng Yuan Jin Gao 2012World Journal of Gastroenterology2012,18,2:52
7美国国立老化研究所与阿尔茨海默病协会诊断指南写作组:阿尔茨海默病源性轻度认知障碍诊断标准推荐显示文摘美国国立老化研究所(NIA)和阿尔茨海默病协会(ADA)组织了一个工作组,负责阿尔茨海默病(AD)痴呆前症状阶段——即本文所称的AD源性轻度认知障碍(MCI)的诊断标准的制订及完善。该工作组制订了以下两套标准:(1)在缺乏相应条件进行先进影像技术及脑脊液检查时,医务人员适用的核心临床标准;(2)适用于包括临床试验在内的科学研究的研究标准。后者纳入了基于影像技术及脑脊液检查的生物标志物的应用。并根据所出现的生物标志物的性质,将最终MCI诊断的确定性程度分为4个级别。而要使生物标志物有效应用于诊断,并在社区医疗服务中规范使用,尚需做大量的工作。McKhann GM Knopman DS Chertkow H Hyman BT Jack CR Jr Kawas CH Klunk WE Koroshetz WJ Manly JJ Mayeux R Mohs RC Morris JC Rossor MN Schehens P Carrillo MC Thies B Weintraub S Phelps CH 贾建平(译) 陆璐(译) 张逸驰(译) 黄丽黄(译) 礼媛(译) 2012中华神经科杂志2012,45,5:51
8美国国立老化研究所与阿尔茨海默病协会诊断指南写作组:阿尔茨海默病痴呆诊断标准的推荐显示文摘由美国国立老化研究所(NIA)和阿尔茨海默病(AD)协会组织了一个工作组,负责修订1984年版AD痴呆的诊断标准。旨在确保修订后的标准具有足够的灵活性,既可供缺乏神经心理学测验、先进的影像技术和脑脊液检查措施的普通医务人员使用,也可供具备上述措施的科研、临床试验的专业研究者使用。新的标准广泛适用于各种原因的痴呆以及专门针对AD痴呆的标准,保留了1984年版标准中的“很可能的AD痴呆”的总体框架。在过去27年的经验基础上,工作组对临床诊断标准做了一些修改,保留了“可能的AD痴呆”的术语,但对其进行了更有针对性的重新定义。在科研用的“很可能的和可能的AD痴呆”的诊断标准中纳入了生物标志物证据。AD痴呆的核心临床标准仍将是临床实践中诊断的基础,但用生物标志物证据来提高AD痴呆诊断的病理生理学特异性也被人们寄予厚望。要实现AD痴呆的生物标志物诊断,还有许多工作摆在面前。McKhann GM Knopman DS Chertkow H Hyman BT Jack CR Jr Kawas CH Klunk WE Koroshetz WJ Manly J J Mayeux R Mohs RC Morris JC Rossor MN Scheltens P Carrillo MC Thies B Weintraub S Phelps CH 贾建平(译) 陆璐(译) 张逸驰(译) 黄丽(译) 韩阅(译) 2012中华神经科杂志2012,45,5:52
9WONCA研究论文摘要汇编——急性颅内出血后血压变异性及转归:INTERACT2研究的析因分析,一项随机对照试验显示文摘背景高血压是急性脑卒中的预后因子,血压变异性或许可以独立预测脑卒中的转归。我们评估了血压变异性对INTERACT2参试者脑卒中预后的预测价值, INTERACT2是一项开放标签随机对照试验。方法 INTERACT2将患有自发性颅内出血(ICH)、高收缩压(150~220 mm Hg)、对早期降压强化疗法无明确适应证或禁忌证的2839例成人纳入研究。将患者随机分为强化治疗组(经静脉给药,1 h内目标收缩压降至<140 mm Hg )和指南推荐的治疗组( ICH 后6 h 内,目标收缩压降至<180 mm Hg)。主要转归为死亡或90 d内发生生活大部分无法自理(改良Rankin量表评分≥3分);次要转归为90 d内改良Rankin量表评分发生顺序移动,调查员在评分时并不知晓患者接受了哪种治疗。根据标准定义血压变异性:在发病头24 h (超急性期)进行5次测量,在发病后2~7 d (急性期)进行不少于12次的测量。采用比例优势逻辑回归模型评价血压变异性与转归之间的关联。血压变异性关键指标为收缩压的标准差,按五分位数加以分类。发现研究者对2645例(93.2%)处于超急性期的患者和2347例(82.7%)处于急性期的患者进行了调查。将两个治疗组的数据一起分析,在超急性期〔最高五分位数校正OR=1.41,95%CI (1.05,1.90); P=0.0167〕和急性期〔最高五分位数校正OR=1.57,95%CI (1.14,2.17); P=0.0124〕,收缩压的标准差与主要转归均呈线性相关。对转归最强的预测指标为超急性期最高收缩压和急性期收缩压的标准差为结果的最强预示因子。对次要转归进行分析,得到的结果与以上结果相似〔超急性期最高五分位数,校正OR=1.43,95%CI (1.14,1.80); P=0.0014;急性期OR=1.46,95%CI (1.13,1.88); P=0.0044〕。解释收缩压变异性似乎可预测急性颅内出血患者的不良转归。早期治疗将收缩压降至140 mm Hg以下获得的收益,可通过平稳并持续血压控制进行强化,避免出现收缩压峰值尤为重要。Manning L Hirakawa Y Arima H 周淑新 2014中国全科医学2014,17,21:56

18Influence of ginsenoside Rg1, a panaxatriol saponin from Panax notoginseng, on renal fibrosis in rats with unilateral ureteral obstruction显示文摘Total saponins of Panax notoginseng (PNS) have been shown to ameliorate renal interstitial fibrosis. Ginsenoside Rg1, a panaxatriol saponin, is one of the major active molecules from PNS. The present study was undertaken to investigate the effect of ginsenoside Rg1 on renal fibrosis in rats with unilateral ureteral obstruction (UUO). The rats were randomly divided into 3 groups: sham-operation (n=15), UUO (n=15) and UUO with ginsenoside Rg1 treatment (n=15, 50 mg per kg body weight, intraperito- neally (i.p.) injected). The rats were sacrificed on Days 7 and 14 after the surgery. Histological examination demonstrated that ginsenoside Rg1 significantly inhibited interstitial fibrosis including tubular injury as well as collagen deposition. α-smooth muscle actin (α-SMA) and E-cadherin are two markers of tubular epithelial-myofibroblast transition (TEMT). Interestingly, ginsenoside Rg1 notably decreased α-SMA expression and simultaneously enhanced E-cadherin expression. The messenger RNA (mRNA) of transforming growth factor-β1 (TGF-β1), a key mediator to regulate TEMT, in the obstructed kidney increased dra- matically, but was found to decrease significantly after administration of ginsenoside Rg1. Further study showed that ginsenoside Rg1 considerably decreased the levels of both active TGF-β1 and phosphorylated Smad2 (pSmad2). Moreover, ginsenoside Rg1 substantially suppressed the expression of thrombospondin-1 (TSP-1), a cytokine which can promote the transcription of TGF-β1 mRNA and the activation of latent TGF-β1. These results suggest that ginsenoside Rg1 inhibits renal interstitial fibrosis in rats with UUO. The mechanism might be partly related to the blocking of TEMT via suppressing the expression of TSP-1.Xi-sheng XIE Man YANG Heng-cuang LIU Chuan ZUO Zi LI Yao DENG Jun-ming FAN 2008Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2008,9,11:34
19A comparison of the Medieval Warm Period, Little Ice Age and 20th century warming simulated by the FGOALS climate system model显示文摘To compare differences among the Medieval Warm Period (MWP), Little Ice Age (LIA), and 20th century global warming (20CW), six sets of transient and equilibrium simulations were generated using the climate system model FGOALS_gl. This model was developed by the State Key Laboratory of Numerical Modeling for Atmospheric Sciences and Geophysical Fluid Dynamics, Institute of Atmospheric Physics, Chinese Academy of Sciences. The results indicate that MWP warming is evident on a global scale, except for at mid-latitudes of the North Pacific. However, the magnitude of the warming is weaker than that in the 20th century. The warming in the high latitudes of the Northern Hemisphere is stronger than that in the Southern Hemisphere. The LIA cooling is also evident on a global scale, with a strong cooling over the high Eurasian continent, while the cooling center is over the Arctic domain. Both the MWP and the 20CW experiments exhibit the strongest warming anomalies in the middle troposphere around 200-300 hPa, but the cooling center of the LIA experiment is seen in the polar surface of the Northern Hemisphere. A comparison of model simulation against the reconstruction indicates that model's performance in simulating the surface air temperature changes during the warm periods is better than that during the cold periods. The consistencies between model and reconstruction in lower latitudes are better than those in high latitudes. Comparison of the inter-annual variability mode of East Asian summer monsoon (EASM) rainfall during the MWP, LIA and 20CW reveals a similar rainfall anomalies pattern. However, the time spectra of the principal component during the three typical periods of the last millennium are different, and the quasi-biannual oscillation is more evident during the two warm periods. At a centennial time scale, the external mode of the EASM variability driven by the changes of effective solar radiation is determined by the changes of large scale land-sea thermal contrast. The rainfall anomalies over the east of 110°E exhibit a meridional homogeneous change pattern, which is different from the meridional out-of-phase change of rainfall anomalies associated with the internal mode.ZHOU TianJun LI Bo MAN WenMin ZHANG LiXia ZHANG Jie 2011Chinese Science Bulletin2011,56,28:32
