1CONSORT 2010说明与详述:报告平行对照随机临床试验指南的更新显示文摘大量证据显示随机对照临床试验(randomised controlled trial,RCT)的报告质量不理想。报告不透明,则读者既不能评判试验结果是否真实可靠,也不能从中提取可用于系统综述的信息。最近的方法学分析表明,报告不充分和设计不合理与对治疗效果产生评价偏倚有关。这种系统误差对RCT损害严重,而RCT正是以其能减少或避免偏倚而被视为评价干预措施的金标准。为了提高RCT的报告质量,一个由专家和编辑组成的工作组制定了临床试验报告的统一标准(Consolidated Standards of Reporting Trials,CONSORT)声明。CONSORT声明于1996年首次发表,并于2001年更新。声明由对照检查清单和流程图组成,供作者在报告RCT时使用。许多核心医学期刊和主要国际性编辑组织都已认可CONSORT声明。该声明促进了对RCT的严格评价和解释。2001年,在对CONSORT进行修订时,人们就已经清楚地认识到,解释和说明制定CONSORT声明的原理,有助于研究人员等撰写或评价临床试验报告。一篇CONSORT说明与详述文章于2001年同2001版CONSORT声明一起发表。2007年1月的专家会议之后,对CONSORT声明作了进一步修订并已发表,即'CONSORT2010声明'。这次更新对原版对照检查清单作了文字上的修改,使其更为明晰,并收入了与一些新近才认识到的主题相关的建议,如选择性报告结局产生的偏倚。说明与详述文件旨在加强人们对CONSORT声明的理解、应用和传播,这次也作了大量修订,对每一项新增或更新的清单条目的含义和增改理由进行了解释,提供了优秀的报告实例,还尽可能地提供了相关的经验性研究的参考文献。文中收入了若干流程图实例。'CONSORT2010声明'、其说明与详述文件,以及相关网站(www.consort-statement.org),对于改进随机临床试验报告必将有所裨益。David Moher Sally Hopewell Kenneth F Schulz Victor Montori Peter C Gφtzsche P J Devereaux Diana Elbourne Matthias Egger Douglas G Altman 周庆辉 卞兆祥 刘建平 2010中西医结合学报2010,8,8:318
2Metal Fabrication by Additive Manufacturing Using Laser and Electron Beam Melting Technologies显示文摘Selective laser melting (SLM) and electron beam melting (EBM) are relatively new rapid, additive manufac- turing technologies which can allow for the fabrication of complex, multi-functional metal or alloy monoliths by CAD-directed, selective melting of precursor powder beds. By altering the beam parameters and scan strategies, new and unusual, even non-equilibrium microstructures can be produced; including controlled microstructural architectures which ideally extend the contemporary materials science and engineering paradigm relating structure-properties-processing-performance. In this study, comparative examples for SLM and EBM fabricated components from pre-alloyed, atomized precursor powders are presented. These include Cu, Ti–6Al–4V, alloy 625 (a Ni-base superalloy), a Co-base superalloy, and 17-4 PH stainless steel. These systems are characterized by optical metallography, scanning and transmission electron microscopy, and X-ray diffraction.Lawrence E. Murr Sara M. Gaytan Diana A.

5西酞普兰及人际心理治疗对合并抑郁症的冠心病患者的影响——加拿大心脏病人群抗抑郁药及心理治疗疗效随机试验(CREATE)显示文摘背景:目前鲜有随机对照试验就冠心病(coronary artery disease,CAD)患者重度抑郁症的治疗效果进行评估,亦无试验同时对抗抑郁药和短期心理治疗进行评估。 目的:在同时患有CAD及重度抑郁症的患者中明确选择性5.羟色胺再摄取抑制剂(西酞普兰)及人际心理治疗(interpersonal psychotherapy,IPT)在减少抑郁症状方面的短期效果。Francois Lespérance Nancy Frasure-Smith Diana Koszycki 顾佳(译) 2007美国医学会杂志(中文版)2007,26,4:36
6Gastrointestinal tract(gut) health in the young pig显示文摘An optimally functioning gastrointestinal tract(GIT) clearly is of importance to the overall metabolism,physiology, disease status and performance of pigs of all stages of growth and development.Recently, the‘health’ of the GIT(‘gut health’) has attracted much attention despite the lack of a clear definition to the term or its aetiology, although in broad terms, ‘gut health’ encompasses a number of physiological and functional features including nutrient digestion and absorption, host metabolism and energy generation, a stable and appropriate microbiota/microbiome, defence mechanisms including barrier function and mucosal immune mechanisms, and the interactions between these components.‘Gut health’ in the newlyweaned(young) pig is of obvious interest due to changes in GIT structure and function associated with the post-weaning transition, and more recently to the upsurge in interest in different feed additives as dietary alternatives/replacements caused by bans/reductions in certain antimicrobial compounds being available in some parts of the world.In the presence of enteric disease(s) after weaning, a deterioration in ‘gut health’ may be synonymous to the overall health of the pig, and although some direct relationships can be drawn between pig performance and efficiency and a ‘healthy' GIT, sometimes this connection is subtler and less obvious, especially in the absence of overt enteric disease(s).The factors and conditions involved in ‘gut health’ are multifactorial, complex, often poorly described and sometimes incorrectly interpreted,although it is evident that perturbations of the GIT can cause an imbalance and disturb the generalized homeostasis.In addition to any enteric diseases or conditions that might arise as a result of these disturbances, other influences will also impact such as the responses occurring in the GIT in the period immediately after weaning, any changes that might occur after a change in diet, and(or) disruptions to meal patterns and hence the flow of nutrients.Ultimately, ‘gut health’ represents the outcome of the GIT in response to its capacity and ability to respond and adapt to the insults and challenges it encounters.John R.Pluske Diana L.Turpin Jae-Cheol Kim 2018Animal Nutrition2018,,2:31
7凡纳滨对虾养殖塘叶绿素a与水质因子的多元回归分析显示文摘2009年4-9月期间,对上海市奉贤区某凡纳滨对虾养殖场22个养殖池塘水体叶绿素a、水温、pH、溶解氧、透明度、悬浮物(SS)、总有机碳(TOC)、五日生化需氧量(BOD5)、高锰酸盐指数(CODMn)等15项水质因子进行测定。取164组测定数据,进行描述性统计,分析叶绿素a与各项因子的相关性系数。分析结果显示,与叶绿素a呈极显著线性正相关的水质因子为SS、TOC、BOD5、CODMn、TN、TP;呈显著正相关的为DO;而叶绿素a与透明度呈极显著线性负相关,与PO43--P呈显著线性负相关;与水温、pH、NO2--N、NO3--N、NH3-N则未呈现显著相关性。根据多元线性回归选择自变量的原则,选择了TOC、TN、PO34--P和TP4项水质因子,建立了叶绿素a与4项水质因子的逐步回归模型:Chl.a=-0.0545+0.00349TOC+0.0153TN-0.418PO43--P+0.276TP(r=0.7155)。利用偏回归系数检验各水质因子对叶绿素a的影响,结果表明,对叶绿素a影响从大到小依次是TP、TOC、PO34--P和TN。研究结果对进一步探讨养殖池塘生态系统的变化规律及水环境质量保护提供了依据。江敏 余根鼎 戴习林 刘利平 顾德平 胡伟国 Diana James S 2010水产学报2010,34,11:20
8报告随机对照试验的CONSORT声明修订版:说明与详述(一)显示文摘有充分的证据表明目前随机对照试验(RCT)的报告质量不尽如人意。最近的方法学调查表明,不恰当的报告及试验设计将使治疗措施的效果产生偏倚。这种系统偏差正严重损害RCT本可摒弃系统偏差的特征。RCT中的系统偏差反映出了科学性差,而科学性差会严重影响正确的伦理标准。科学家和编辑们共同制定了CONSORT(试验报告统一标准,ConsolidatedStandardsofReportingTrials,)声明以提高RCT报告质量。CONSORT声明由清单和流程图组成,作者可用来报告RCT。许多优秀期刊和重要国际性编辑组织已经采用CONSORT声明。CONSORT声明为作者提高临床试验报告质量提供指南,使得评价和解释RCT结果更方便。此文旨在增强大家对CONSORT声明的理解、应用和传播,并对每个清单项目的意义和原理进行了说明。很多项目都列出优秀报告的示例,并尽可能参考相关的经验性研究,还列出几个流程图的示例。CONSORT声明的说明和详述文件在以下网址可找到:http://gffzzff905fc352db4ba6hqw9fvf6xcc606k06.ffgz.tsg.suse.edu.cn,这是提高随机对照试验报告质量的有益资源。Douglas G.Altman Kenneth F.Schulz David Moher Matthias Egger Frank Davidoff Diana Elbourne Peter C.Gφtzsch Thomas Lang the CONSORT Group 刘雪梅 2005中国循证医学杂志2005,5,9:19

10indocyanine green-based fluorescence imaging in visceral and hepatobiliary and pancreatic surgery:State of the art and future directions显示文摘In recent years, the use of fluorescence-guided surgery(FGS) to treat benign and malignant visceral, hepatobiliary and pancreatic neoplasms has significantly increased. FGS relies on the fluorescence signal emitted by injected substances(fluorophores) after being illuminated by ad hoc laser sources to help guide the surgical procedure and provide the surgeon with real-time visualization of the fluorescent structures of interest that would be otherwise invisible. This review surveys and discusses the most common and emerging clinical applications of indocyanine green(ICG)-based fluorescence in visceral, hepatobiliary and pancreatic surgery. The analysis, findings, and discussion presented here rely on the authors' significant experience with this technique in their medical institutions, an up-to-date review of the most relevant articles published on this topic between 2014 and 2018, and lengthy discussions with key opinion leaders in the field during recent conferences and congresses. For each application, the benefits and limitations of this technique, as well as applicable future directions, are described. The imaging of fluorescence emitted by ICG is a simple, fast,relatively inexpensive, and harmless tool with numerous different applications in surgery for both neoplasms and benign pathologies of the visceral and hepatobiliary systems. The ever-increasing availability of visual systems that can utilize this tool will transform some of these applications into the standard of care in the near future. Further studies are needed to evaluate the strengths and weaknesses of each application of ICG-based fluorescence imaging in abdominal surgery.Gian Luca Baiocchi Michele Diana Luigi Boni 2018World Journal of Gastroenterology2018,24,27:19

14Reducing preoperative fasting time: A trend based on evidence显示文摘Preoperative fasting is mandatory before anesthesia to reduce the risk of aspiration.However,the prescribed 6-8 h of fasting is usually prolonged to 12-16 h for various reasons.Prolonged fasting triggers a metabolic response that precipitates gluconeogenesis and increases the organic response to trauma.Various randomized trials and meta-analyses have consistently shown that is safe to reduce the preoperative fasting time with a carbohydrate-rich drink up to 2 h before surgery.Benefits related to this shorter preoperative fasting include the reduction of postoperative gastrointestinal discomfort and insulin resistance.New formulas containing amino acids such as glutamine and other peptides are being studied and are promising candidates to be used to reduce preoperative fasting time.JoséEduardo de Aguilar-Nascimento Diana Borges Dock-Nascimento 2010World Journal of Gastrointestinal Surgery2010,2,3:17

16Biological response to prosthetic debris显示文摘Joint arthroplasty had revolutionized the outcome of orthopaedic surgery. Extensive and collaborative work of many innovator surgeons had led to the development of durable bearing surfaces, yet no single material is considered absolutely perfect. Generation of wear debris from any part of the prosthesis is unavoidable. Implant loosening secondary to osteolysis is the most common mode of failure of arthroplasty. Osteolysis is the resultant of complex contribution of the generated wear debris and the mechanical instability of the prosthetic components. Roughly speaking, all orthopedic biomaterials may induce a universal biologic hostresponse to generated wear débris with little specific characteristics for each material; but some debris has been shown to be more cytotoxic than others. Prosthetic wear debris induces an extensive biological cascade of adverse cellular responses, where macrophages are the main cellular type involved in this hostile inflammatory process. Macrophages cause osteolysis indirectly by releasing numerous chemotactic inflammatory mediators, and directly by resorbing bone with their membrane microstructures. The bio-reactivity of wear particles depends on two major elements: particle characteristics(size, concentration and composition) and host characteristics. While any particle type may enhance hostile cellular reaction, cytological examination demonstrated that more than 70% of the debris burden is constituted of polyethylene particles. Comprehensive understanding of the intricate process of osteolysis is of utmost importance for future development of therapeutic modalities that may delay or prevent the disease progression.Diana Bitar Javad Parvizi 2015World Journal of Orthopedics2015,6,2:16
17Diagnostic aids for detection of oral precancerous conditions显示文摘Oral cancer has a tendency to be detected at late stage which is detrimental to the patients because of its high mortality and morbidity rates. Early detection of oral cancer is therefore important to reduce the burden of this devastating disease. In this review article, the most common oral precancerous lesions are discussed and the importance of early diagnosis is emphasized. In addition, the most common non-invasive oral cancer devices that can aid the general practitioners in early diagnosis are also discussed.Diana V Messadi 2013International Journal of Oral Science2013,5,2:15

20Effectiveness of Acupuncture on Pain, Physical Function and Health-Related Quality of Life in Patients with Rheumatoid Arthritis: A Systematic Review of Quantitative Evidence显示文摘Objective: To identify and synthesize the most recent available evidence of effectiveness of acupuncture on pain, physical function and health-related quality of life(HRQoL) in patients with rheumatoid arthritis(RA). Methods: A comprehensive search of 12 Western and Chinese databases was undertaken from their inception up to end of 2016. Randomized controlled trials(RCTs), concerning patients with RA treated with needle acupuncture, written in English, Portuguese, German or Chinese were included. Primary outcomes included pain, physical function and HRQoL. Secondary outcomes included morning stiffness, functional impairment, number of tender and swollen joints and serum concentrations of inflamatory markers. Methodological quality was assessed by three independent reviewers using the standardized critical appraisal instrument from the Joanna Briggs Institute Meta-Analysis of Statistics Assessment and Review Instrument. Results: Twenty-two studies met the inclusion criteria. Of those, 9 studies were excluded after assessment of their methodological quality. The remaining 13 original RCTs included 974 patients. Ten of these studies published in China, showed favorable statistical significant effects of acupuncture in relieving symptoms of RA compared with controls. Conclusions: Evidence suggests that acupuncture interventions may have a positive effect in pain relief, physical function and HRQo L in RA patients. However, due to the heterogeneity and methodologic limitations of the studies included in this systematic review, evidence is not strong enough to produce a best practice guideline.Susana Seca Diana Miranda Daniela Cardoso Bernice Nogueira Henry J.Greten Antonio Cabrita Manuel Alves Rodrigues 2019Chinese Journal of Integrative Medicine2019,25,9:11
