1中国两栖动物保护需求总述显示文摘通过对中国两栖动物物种生物多样性现状的全面分析,与世界许多国家相比,中国是一个重要的全球优先保护地区.横断山区、南岭山区和武夷山区3个区域的两栖动物物种多样性特别丰富.有尾两栖类物种较无尾类受胁程度更高.几个物种数相对较少的铃蟾科、隐腮鲵科、小鲵科和蝾螈科显示出了高的受胁倾向.像世界其它地方一样,高海拔地区溪流繁殖的森林物种受胁程度更高.对中国两栖动物而言,生境丧失、污染和过度捕捉是最主要的致危因素.过度捕捉虽然影响不如生境丧失深远,但它更可能导致一个物种种群的快速衰落.针对5个方面的保护挑战,提出了优先研究领域和保护行动方面的建议.谢锋 刘惠宁 Simon N Stuart Janice S Chanson Neil A Cox Debra L Fischman 2006中国科学(C辑)2006,36,6:28
2Conservation needs of amphibians in China: A review显示文摘The conservation status of all the amphibians in China is analyzed,and the country is shown to be a global priority for conservation in comparison to many other countries of the world.Three Chinese regions are particularly rich in amphibian diversity:Hengduan,Nanling,and Wuyi mountains.Sala-manders are more threatened than frogs and toads.Several smaller families show a high propensity to become seriously threatened:Bombinatoridae,Cryptobranchidae,Hynobiidae and Salamandridae.Like other parts of the world,stream-breeding,high-elevation forest amphibians have a much higher likeli-hood of being seriously threatened.Habitat loss,pollution,and over-harvesting are the most serious threats to Chinese amphibians.Over-harvesting is a less pervasive threat than habitat loss,but it is more likely to drive a species into rapid decline.Five conservation challenges are mentioned with recommendations for the highest priority research and conservation actions.Michael Wai Neng LAU Simon N STUART Janice S CHANSON Neil A COX Debra L FISCHMAN 2007Science China(Life Sciences)2007,50,2:12
3Randomized trial in malignant biliary obstruction:Plastic vs partially covered metal stents显示文摘AIM:To compare efficacy and complications of par-tially covered self-expandable metal stent(pcSEMS)to plastic stent(PS)in patients treated for malignant,infrahilar biliary obstruction.METHODS:Multicenter prospective randomized clinical trial with treatment allocation to a pcWallstent(SEMS)or a 10 French PS.Palliative patients aged≥18,for infrahilar malignant biliary obstruction and a Karnofsky performance scale index>60%from 6 participating North American university centers.Primary endpoint was time to stent failure,with secondary outcomes of death,adverse events,Karnofsky performance score and short-form-36 scale administered on a three-monthly basis for up to 2 years.Survival analyses were performed for stent failure and death,with Cox proportional hazards regression models to determine significant predictive characteristics.RESULTS:Eighty-five patients were accrued over 37mo,42 were randomized to the SEMS group and 83patients were available for analyses.Time to stent failure was 385.3±52.5 d in the SEMS and 153.3±19.8 d in the PS group,P=0.006.Time to death did not differ between groups(192.3±23.4 d for SEMS vs211.5±28.0 d for PS,P=0.70).The only significant predictor was treatment allocation,relating to the time to stent failure(P=0.01).Amongst other measured outcomes,only cholangitis differed,being more common in the PS group(4.9%vs 24.5%,P=0.029).The small number of patients in follow-up limits longitudinal assessments of performance and quality of life.From an initially planned 120 patients,only 85 patients were recruited.CONCLUSION:Partially covered SEMS result in a longer duration till stent failure without increased complication rates,yet without accompanying measurable benefits in survival,performance,or quality of life.Peter L Moses Khalid M AlNaamani Alan N Barkun Stuart R Gordon Roger D Mitty M Stanley Branch Thomas E Kowalski Myriam Martel Viviane Adam 2013World Journal of Gastroenterology2013,19,46:6

7基于一个大型随机试验预测稳定性心绞痛队列患者死亡、心肌梗死和卒中的危险评分显示文摘目的对需要抗心绞痛治疗并且左心室功能代偿症状稳定的心绞痛患者建立预测全因死亡、心肌梗死和导致致残性卒中的复合危险评分。设计大型多中心临床试验数据的多变量Cox回归分析。背景西欧、以色列、加拿大、澳大利亚和新西兰的心脏专科门诊患者。入选者7311例具有全部需要资料的患者被入选。主要结局的测量指标平均随访4.9年时间内所有原因的死亡、心肌梗死或者致残性卒中。结果1063例患者发生任何原因死亡或者持久性心肌梗死或者致残性卒中。这些复合终点的5年危险性在危险性最低的十分位患者为4%,而在危险性最高的十分位患者为35%。危险评分结合16项临床常规变量的降序排序是:年龄、左心室射血分数、吸烟、白细胞计数、糖尿病、随机血糖浓度、肌酐浓度、既往卒中病史、1周至少1次心绞痛发作、冠状动脉造影发现(如果能够获得)、降脂治疗、QT间期、收缩期血压≥150mmHg、抗心绞痛药物数量、陈旧性心肌梗死以及性别。把这个模型分别应用于任何原因所致的死亡、心肌梗死和卒中进行预测评估,所得的结果相似。危险评分似乎不能预测事件性质(39%的死亡、46%心肌梗死以及15%致残性卒中)或者冠状动脉造影或血管重建率(占29%的患者)。结论该危险评分对客观地决定稳定性心绞痛患者进一步治疗措施以减少重要预后事件发生是有帮助的。该危险评分同样可以用于将来的计划性试验。Tim C Clayton Stuart J Pocock Jacobus Lubsen Zoltán Vokó Bridget-Anne Kirwan Keith A A Fox Philip A Poole-Wilson 2006英国医学杂志中文版2006,9,1:2

12Intra-islet endothelial cell and β-cell crosstalk: Implication for islet cell transplantation显示文摘The intra-islet microvasculature is a critical interface between the blood and islet endocrine cells governing a number of cellular and pathophysiological processes associated with the pancreatic tissue. A growing body of evidence indicates a strong functional and physical interdependency of β-cells with endothelial cells(ECs), the building blocks of islet microvasculature. Intra-islet ECs, actively regulate vascular permeability and appear to play a role in fine-tuning blood glucose sensing and regulation. These cells also tend to behave as 'guardians', controlling the expression and movement of a number of important immune mediators, thereby strongly contributing to the physiology of islets. This review will focus on the molecular signalling and crosstalk between the intra-islet ECs and β-cells and how their relationship can be a potential target for intervention strategies in islet pathology and islet transplantation.Siddharth Narayanan Gopalakrishnan Loganathan Maheswaran Dhanasekaran William Tucker Ankit Patel Venugopal Subhashree SriPrakash Mokshagundam Michael G Hughes Stuart K Williams Appakalai N Balamurugan 2017World Journal of Transplantation2017,7,2:1
