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
3Incidental non-benign gallbladder histopathology after cholecystectomy in an United Kingdom population: Need for routine histological analysis?显示文摘AIM To analyse the range of histopathology detected in the largest published United Kingdom series of cholecystectomy specimens and to evaluate the rational for selective histopathological analysis.METHODS Incidental gallbladder malignancy is rare in the United Kingdom with recent literature supporting selective histological assessment of gallbladders after routine cholecystectomy.All cholecystectomy gallbladder specimens examined by the histopathology department at our hospital during a five year period between March 2008 and March 2013 were retrospectively analysed.Further data was collected on all specimens demonstrating carcinoma,dysplasia and polypoid growths.RESULTS The study included 4027 patients.The majority(97%) of specimens exhibited gallstone or cholecystitis related disease.Polyps were demonstrated in 44(1.09%),the majority of which were cholesterol based(41/44).Dysplasia,ranging from low to multifocal high-grade was demonstrated in 55(1.37%).Incidental primary gallbladder adenocarcinoma was detected in 6 specimens(0.15%,5 female and 1 male),and a single gallbladder revealed carcinoma in situ(0.02%).This large single centre study demonstrated a full range of gallbladder disease from cholecystectomy specimens,including more than 1% neoplastic histology and two cases of macroscopically occult gallbladder malignancies.CONCLUSION Routine histological evaluation of all elective and emergency cholecystectomies is justified in a United Kingdom population as selective analysis has potential to miss potentially curable life threatening pathology.Krashna Patel Khaled Dajani Satheesh Iype Nikolaos A Chatzizacharias Saranya Vickramarajah Susan Davies Rebecca Brais Siong S Liau Simon Harper Asif Jah Raaj K Praseedom Emmanuel L Huguet 2016World Journal of Gastrointestinal Surgery2016,8,10:2
