1QUADAS评价:一种用于诊断性研究的质量评价工具(修订版)显示文摘背景 QUADAS是一种新近发展起来的诊断性研究的质量评价工具。虽然已有系统评价采用了QUADAS,但尚未得以正式确证。本研究的目的是评价QUADAS的有效性和实用性。方法3位评价者采用QUADAS独立评价30项研究的质量。比较每位评价者的评分与最终结论之间的意见一致度。这主要是通过比较所有QUADAS条目的总分和每个单项的得分来实现的。20位曾在其系统评价中使用过QUADAS的评价者就其使用经验完成一份简短的问卷。结果就所有条目而言,每位评价者的评分与最终结论之间的意见一致度分别达到了91%、90%和85%。就单项QUADAS条目而言,一致度在50%至100%之间,中位值是90%。与难以解释的试验结果和退出病例相关的条目,评分结果差异最大。有关QUADAS内容的反馈意见普遍较好,仅少数评价者提出了有关QUADAS涵盖面、使用便利性、评分说明的清晰度及有效性方面的问题。结论QUADAS内容本身无需作大的修改。评价过程的主要困难出现在难以解释的试验结果和退出病例这2个条目的评分上。对这些条目的评分指南提出了修改意见。评价者必需根据其系统评价制定相应的评分指南,并确保所有评价者都清楚如何评分。评价者还应考虑是否所有的QUADAS条目都与其系统评价相关,以及其他质量条目是否应作为其系统评价的评价部分。Penny F Whiting Marie E Weswood Anne WS Rutjes Johannes B Reitsma Patrick NM Bossuyt Jos Kleijnen 马章淳 钱楠 2007中国循证医学杂志2007,7,7:64
2Great progress in study on aerosol and its impact on the global environment显示文摘The transport from atmosphere is a more important pathway than that from rivers for certain elements and compounds in the remote ocean. The desert and those arid/semi-arid areas in the northwest of China and the Loess Plateau are the sources of those aerosols over the Pacific. Atmospheric iron is the limiting factor of the productivity in certain ocean regions. The dust storms must now be seen as repeated sources of pollution elements as well as soil elements to the East China Sea and, farther out, to the North Pacific Ocean and even to the USA. The long-range transport of aerosols, especially the dust storm, from China and the positive feedbacks of iron coupled with sulfur in atmosphere might be one of the important mechanisms that would affect the primary productivity in the Pacific and/or the global climate change and deserve to be further studied. It can be seen clearly that the dust storms would affect not only the health of human beings and the local or regional climate, but also the global climate change that has been the focus of environmental study internationally.ZHUANG Guoshun, HUANG Ronghui, WANG Mingxing, Q.

4Management and outcome of hepatocellular adenoma with massive bleeding at presentation显示文摘AIM To evaluate outcome of acute management and risk of rebleeding in patients with massive hemorrhage due to hepatocellular adenoma(HCA). METHODS This retrospective cohort study included all consecutive patients who presented to our hospital with massive hemorrhage(grade Ⅱ or Ⅲ) due to ruptured HCA and were admitted for observation and/or intervention between 1999-2016. The diagnosis of HCA was based on radiological findings from contrastenhanced magnetic resonance imaging(MRI) or pathological findings from biopsy or resection of the HCA. Hemorrhage was diagnosed based on findings from computed tomography or MRI. Medical records were reviewed for demographic features, clinical presentation, tumor features, initial and subsequent management, short-and long-term complications and patient and lesion follow-up. RESULTS All patients were female(n = 23). Treatment in the acute phase consisted of embolization(n = 9, 39.1%), conservative therapy(n = 13, 56.5%), andother intervention(n = 1, 4.3%). Median hemoglobin level decreased significantly more on days 0-3 in the intervention group than in the patients initially treated conservatively(0.9 mmol/L vs 2.4 mmol/L respectively, P = 0.006). In total, 4 patients suffered severe shortterm complications, which included hypovolemic shock, acute liver failure and abscess formation. After a median follow-up of 36 mo, tumor regression in nonsurgically treated patients occurred with a median reduction of 76 mm down to 25 mm. Four patients underwent secondary(elective) treatment(i.e., tumor resection) to address HCA size of > 5 cm and/or desire for future pregnancy. One case of rebleeding was documented(4.3%). None of the patients experienced long-term complication(mean follow-up time: 36 mo). CONCLUSION With a 4.3% risk of rebleeding, secondary(elective) treatment of HCA after massive hemorrhage may only be considered in patients with persistent HCA > 5 cm.Anne J Klompenhouwer Robert A de Man Maarten GJ Thomeer Jan NM Ijzermans 2017World Journal of Gastroenterology2017,23,25:5
5Jackknife and Bootstrap Tests of the Composition Vector Trees显示文摘Composition vector trees (CVTrees) are inferred from whole-genome data by an alignment-free and parameter-free method. The agreement of these trees with the corresponding taxonomy provides an objective justification of the inferred phylogeny. In this work, we show the stability and self-consistency of CVTrees by performing bootstrap and jackknife re-sampling tests adapted to this alignment-free approach. Our ultimate goal is to advocate the viewpoint that time-consuming statistical re-sampling tests can be avoided at all in using this alignment-free approach. Agreement with taxonomy should be taken as a major criterion to estimate prokaryotic phylogenetic trees.Guanghong Zuo1,2, Zhao Xu1,3, Hongjie Yu1,4, and Bailin Hao1,5,6 1T-Life Research Center & Department of Physics, Fudan University, Shanghai 200433, China 2Shanghai Institute of Applied Physics, Chinese Acadamy of Sciences, Shanghai 201800, China 3Applied Biosystems, Inc., Beijing 100027, China 4Fudan-VARI Center for Genetic Epidemiology, Fudan University, Shanghai 200433, China 5Institute of Theoretical Physics, Chinese Acadamy of Sciences, Beijing 100190, China 6Santa Fe Institute, Santa Fe, NM 87505, USA. 2010Genomics, Proteomics & Bioinformatics2010,8,4:5

Relations of arterial stiffness with postural change in mean arterial pressure in middle-aged adults:the Framingham heart study. Hyperten- sion,2017,69(4) :685-690.站立位血压稳定调节受损可导致不良结果,包括跌倒、晕厥和定向障碍。平均动脉压(meanarterialpressure,MAP)通常在站立位时增加,然而,站立位MAP增加不足或减少可能导致脑灌注减少。已有研究报道,在动脉硬度增加的老年人中存在体位性低血压,年轻至中年人MAP的体位性改变与动脉硬度的相关性尚未阐明。该研究分析了Framingham心脏研究第3代队列中的受试者3205人(女性1693人,占53%)的直立性血压反应和全面血液动力学数据。Torjesen A Cooper LL Rong J Larson MG Hamburg NM Levy D Benjamin EJ Vasan RS Mitchell GF 刘莉 叶鹏 2017中华高血压杂志2017,25,3:5
8Daily Ambrosia Pollen Concentration in the Air of Ankara,Turkey (1990-1999)显示文摘The airborne ragweed pollen spectrum was investigated in the air of Ankara, Turkey for aperiod of ten years (1990-1999) using a Burkard seven-day volumetric recording trap. In our study period,long distance transported Ambrosia pollen has been registered. Daily pollen levels varied from low to highin Burge抯 system. In last three years, the pollen concentration of Ambrosia showed a clear increasingtendency. Our results prove that ragweed pollen may be an important threat for ragweed sensitive patientsin Ankara city in near future.Ayse KAPLAN Nazmiye SAKIYAN Nmǖnevver PINAR 2003Acta Botanica Sinica2003,45,12:4

12碳青霉烯类抗生素引发癫痫发作风险:一项荟萃分析显示文摘碳青霉烯类是一种广谱抗生素,常用于复杂和严重的细菌感染。多数患者对碳青霉烯类抗生素耐受性良好。临床医师通常认为在碳青霉烯类抗生素中亚胺培南最易引发癫痫发作,这一点在文献中尚存在争议。根据美国FDA 批准的药物说明书,亚胺培南、美罗培南和厄他培南诱发癫痫发作的频率分别为0.4%、0.7%和0.5%。文章荟萃分析碳青霉烯类引发癫痫发作的随机对照研究,以评估不同品种碳青霉烯类抗生素导致癫痫发作的风险,直接比较各碳青霉烯类引发癫痫发作的风险。Cannon JP Lee TA Clark NM 肖广辉 汪复 2015中国感染与化疗杂志2015,15,3:3
