1近百年中国气温变化中的不确定性估计显示文摘利用均一化的中国近百年气温观测数据,结合英国East Anglia大学气候研究中心(CRU)的CRUTEM3气温数据集中中国周边国家长序列资料对20世纪前50年资料进行了补充,研制了中国及周边地区近百年逐月5°×5°气温网格数据集,并综合系统考虑了该气温数据集中存在的3类误差(台站误差、抽样误差和偏差误差)导致的不确定性水平,重新构建了近百年全国气温变化序列,并给出了各种不确定性水平,得出了近百年中国气温变化的最新估计.基于上述数据集系统性地对中国近100年地表气温变化趋势进行了重新估计.结果显示:1900~2006年中国气温变化速度为(0.09±0.017)℃/10a;冬季最大,为(0.14±0.021)℃/10a;夏季最小为(0.04±0.017)℃/10a;春季为(0.11±0.021)℃/10a;秋季为(0.07±0.017)℃/10a.近50年(1954~2006年)气温增暖趋势约为(0.26±0.032)℃/10a,近30年(1979~2006年)增暖趋势为(0.45±0.13)℃/10a,气温增暖速率呈明显加剧趋势,值得引起注意.从地理分布上来看,东北、西北和华北地区的增暖幅度最为明显,而西南、华南地区增暖幅度最小,这种变化在近100,50和30年具有较好的一致性.李庆祥 董文杰 李伟 高小蓉 JONES Phil KENNEDY John PARKER David 2010科学通报2010,55,16:82
22018加拿大心境障碍与焦虑障碍治疗协作组/国际双相障碍学会指南:双相障碍的管理显示文摘加拿大心境障碍与焦虑障碍治疗协作组(Canadian Network for Mood and Anxiety Treatments,CANMAT)曾于2005年发布了第1版双相障碍管理指南,并分别于2007、2009和2013年对该指南进行了更新,其中最近的2次更新是与国际双相障碍学会(International Society for Bipolar Disorders,ISBD)合作完成。2018版CANMAT/ISBD双相障碍治疗指南(以下简称指南)反映了自2005年首版指南发表以来本领域取得的重大进展,包括疾病诊断与疾病管理的更新以及药物治疗与心理治疗的近期研究进展。这些前沿进展中综合考虑了循证证据的级别,并基于治疗疗效、临床实践经验、安全性、耐受性和药物导致的转相风险等,对一线、二线及三线治疗方案进行了简明而清晰的推荐。本指南中新增内容涵盖了双相Ⅰ型障碍(BD-Ⅰ)的躁狂发作急性期、抑郁发作急性期和双相障碍维持期的一线及二线治疗推荐等级划分。这种对治疗推荐等级的划分综合考虑了治疗方法对双相障碍不同时相的影响,将进一步帮助临床医生做出基于循证证据的治疗决策。锂盐、喹硫平、双丙戊酸盐、阿塞那平、阿立哌唑、帕利哌酮、利培酮和卡利拉嗪单药或联合使用被推荐为躁狂发作急性期的一线治疗选择。BD-Ⅰ抑郁期的一线治疗选择包括喹硫平、鲁拉西酮、锂盐、拉莫三嗪单药,鲁拉西酮联合锂盐或双丙戊酸盐或拉莫三嗪辅助治疗。尽管急性期治疗有效的药物通常应继续用于BD-Ⅰ的维持期治疗,但也存在一些特殊情况(例如抗抑郁药)。现有数据表明,锂盐、喹硫平、双丙戊酸盐、拉莫三嗪、阿塞那平和阿立哌唑单药或联合治疗应被视为维持治疗的初始或更换治疗方案时的一线选择。除了探讨BD-Ⅰ的相关问题外,本指南中还对双相Ⅱ型障碍(BD-Ⅱ)的临床管理进行了系统回顾并给予治疗推荐,同时针对特殊人群也有相关推荐,如处于各个生殖周期的女性、儿童、青少年和老年人。此外,本指南中还讨论了特定精神疾病及共病(如物质滥用、焦虑障碍和代谢性疾病)的影响。最后,本指南中概述了安全性和药物监测的相关问题。CANMAT/ISBD工作组希望本指南能够成为全球临床医生的实用工具。Lakshmi N Yatham Sidney H Kennedy Sagar V Parikh Ayal Sehaffer David J Bond Benicio N Frey Verinder Sharma Benjamin I Goldstein Soham Rej Serge Beaulieu Martin Alda Glenda MaeQueen Roumen V Milev Arun Ravindran Claire O'Donovan Diane Mclntosh Raymond W Lam Gustavo Vazquez Flavio Kapczinski Roger S Melntyre Jan Kozicky Shigenobu Kanba Beny Lafer Trisha Suppes Joseph R Calabrese Eduard Vieta Gin Malhi Robert M Post Michael Berk 胡晨(译) 王刚(译) 2019中华精神科杂志2019,52,1:25

4Numerical aerodynamic analysis of bluff bodies at a high Reynolds number with three-dimensional CFD modeling显示文摘This paper focuses on numerical simulations of bluff body aerodynamics with three-dimensional CFD(computational fluid dynamics) modeling,where a computational scheme for fluid-structure interactions is implemented.The choice of an appropriate turbulence model for the computational modeling of bluff body aerodynamics using both two-dimensional and three-dimensional CFD numerical simulations is also considered.An efficient mesh control method which employs the mesh deformation technique is proposed to achieve better simulation results.Several long-span deck sections are chosen as examples which were stationary and pitching at a high Reynolds number.With the proposed CFD method and turbulence models,the force coefficients and flutter derivatives thus obtained are compared with the experimental measurement results and computed values completely from commercial software.Finally,a discussion on the effects of oscillation amplitude on the flutter instability of a bluff body is carried out with extended numerical simulations.These numerical analysis results demonstrate that the proposed three-dimensional CFD method,with proper turbulence modeling,has good accuracy and significant benefits for aerodynamic analysis and computational FSI studies of bluff bodies.BAI YuGuang YANG Kai SUN DongKe ZHANG YuGuang KENNEDY David WILLIAMS Fred GAO XiaoWei 2013Science China(Physics,Mechanics & Astronomy)2013,56,2:4

7Early infant male circumcision:Systematic review,risk-benefit analysis,and progress in policy显示文摘AIM To determine whether recent evidence-based United States polices on male circumcision(MC) apply to comparable Anglophone countries,Australia and New Zealand.METHODS Articles in 2005 through 2015 were retrieved from PubM ed using the keyword 'circumcision' together with 36 relevant subtopics.A further PubM ed search was performed for articles published in 2016.Searches of the EMBASE and Cochrane databases did not yield additional citable articles.Articles were assessed for quality and those rated 2+ and above according to the Scottish Intercollegiate Grading System were studied further.The most relevant andrepresentative of the topic were included.Bibliographies were examined to retrieve further key references.Randomized controlled trials,recent high quality systematic reviews or meta-analyses(level 1++ or 1+ evidence) were prioritized for inclusion.A risk-benefit analysis of articles rated for quality was performed.For efficiency and reliability,recent randomized controlled trials,metaanalyses,high quality systematic reviews and large welldesigned studies were used if available.Internet searches were conducted for other relevant information,including policies and Australian data on claims under Medicare for MC.RESULTS Evidence-based policy statements by the American Academy of Pediatrics(AAP) and the Centers for Disease Control and Prevention(CDC) support infant and later age male circumcision(MC) as a desirable public health measure.Our systematic review of relevant literature over the past decade yielded 140 journal articles that met our inclusion criteria.Together,these showed that early infant MC confers immediate and lifelong benefits by protecting against urinary tract infections having potential adverse long-term renal effects,phimosis that causes difficult and painful erections and 'ballooning' during urination,inflammatory skin conditions,inferior penile hygiene,candidiasis,various sexually transmissible infections in both sexes,genital ulcers,and penile,prostate and cervical cancer.Our risk-benefit analysis showed that benefits exceeded procedural risks,which are predominantly minor,by up to 200 to 1.We estimated that more than 1 in 2 uncircumcised males will experience an adverse foreskin-related medical condition over their lifetime.Wide-ranging evidence from surveys,physiological measurements,and the anatomical location of penile sensory receptors responsible for sexual sensation strongly and consistently suggested that MC has no detrimental effect on sexual function,sensitivity or pleasure.United States studies showed that early infant MC is cost saving.The evidence supporting early infant MC has further strengthened since the positive AAP and CDC reviews.CONCLUSION Affirmative MC policies are needed in Australia and New Zealand.Routine provision of accurate,unbiased education,and access in public hospitals,will maximize health and financial benefits.Brian J Morris Sean E Kennedy Alex D Wodak Adrian Mindel David Golovsky Leslie Schrieber Eugenie R Lumbers David J Handelsman John B Ziegler 2017World Journal of Clinical Pediatrics2017,6,1:2

10Impacts of long-term land-use changes on herd size and mobility among pastoral households in Amboseli ecosystem,Kenya显示文摘Introduction:Long-term changes in rangeland ecosystems of the world have impacted on the livestock production,a key livelihood strategy in these areas.This paper presents perceptions of the pastoral community on the dynamics of pastoral livelihoods under three land-use types namely nomadic,semi-nomadic,and sedentary in Amboseli ecosystem located in southern Kenya.Structured questionnaire was used to collect data concerning household livestock herds,perceived livestock trends and their causes,importance of migration,sedentarization,and land subdivision,and were administered to respondents randomly selected from the three land-use types.Results:The study shows that the livestock herd size was higher in nomadic(117.1)and lower in sedentary(56.6)land-use site.The majority of the respondents in nomadic(79%),semi-nomadic(73%),and sedentary(64%)reported a declining trend in household herd size.The declines were mostly attributed to recurrent droughts and loss of grazing lands.Conclusions:Pastoralism remains an important livelihood strategy to majority of households in the study area;therefore,to achieve sustainable livelihood strategies,grazing lands should be maintained.Kennedy Sakimba Kimiti David Western Judith Syombua Mbau Oliver Vivian Wasonga 2018Ecological Processes2018,7,1:1
