1系统综述与网状Meta分析的PRISMA扩展声明显示文摘PRISMA声明旨在提高系统综述和META分析报告的完整性,该声明已经广泛用于指导系统综述和META分析的报告和发表。原始的PRISMA声明是针对两种干预措施比较的传统的系统综述与META分析而制定的,然而,随着多种干预措施比较的系统综述的发展,实施和报告这一类系统综述面临较大挑战。此时,针对网状META分析的PRISMA扩展声明应运而生,旨在提高网状META分析系统综述的报告质量。PRISMA扩展声明是由专家们通过DELPHI调查、面对面讨论和共识大会而最终确立的。PRISMA扩展声明是在原始PRISMA声明的报告清单的基础上经过修改,最终确定了32个条目,每个条目均与网状META分析报告的内容直接相关。本文对网状META分析的PRISMA扩展声明进行了阐述,对报告清单各条目进行了举例说明,并详细说明了在原始PRISMA声明的基础上新增和修改各条目的理由。此外,PRISMA扩展声明强调了在网状META分析的实际操作中需要重点关注的信息。本文的目标读者包括网状META分析的作者与读者,以及期刊杂志的编辑与同行评审。李志霞 杨俊 叶欣 周凌波 杨智荣 孙凤 詹思延 Brian Hutton Georgia Salanti Deborah M.Caldwell Anna Chaimani Christopher H.Schmid Chris Cameron John P.A.Ioannidis Sharon Straus Kristian Thorlund Jeroen P.Jansen Cynthia Mulrow Ferrán Catalá-López Peter C.Gozsche Kay Dickersin Isabelle Boutron Douglas G.Altman David Moher 2016中国循证心血管医学杂志2016,8,6:11
2The role of antioxidants and pro-oxidants in colon cancer显示文摘This review focuses on the roles antioxidants and prooxidants in colorectal cancer(CRC).Considerable evidence suggests that environmental factors play key roles in the incidence of sporadic CRC.If pro-oxidant factors play an etiological role in CRC it is reasonable to expect causal interconnections between the wellcharacterized risk factors for CRC,oxidative stress and genotoxicity.Cigarette smoking,a high dietary consumption of n-6 polyunsaturated fatty acids and alcohol intake are all associated with increased CRC risk.These risk factors are all pro-oxidant stressors and their connections to oxidative stress,the intestinal microbiome,intestinal microfold cells,cyclooxygenase-2 and CRCare detailed in this review.While a strong case can be made for pro-oxidant stressors in causing CRC,the role of food antioxidants in preventing CRC is less certain.It is clear that not every micronutrient with antioxidant activity can prevent CRC.It is plausible,however,that the optimal food antioxidants for preventing CRC have not yet been critically evaluated.Increasing evidence suggests that RRR-gamma-tocopherol(the primary dietary form of vitamin E)or other'non-alpha-tocopherol'forms of vitamin E(e.g.,tocotrienols)might be effective.Aspirin is an antioxidant and its consumption is linked to a decreased risk of CRC.William L Stone Koyamangalath Krishnan Sharon E Campbell Victoria E Palau 2014World Journal of Gastrointestinal Oncology2014,6,3:4
3Single-atom heterogeneous catalysts based on distinct carbon nitride scaffolds显示文摘Carbon nitrides integrating macroheterocycles offer unique potential as hosts for stabilizing metal atoms due to their rich electronic structure. To date, only graphitic heptazine-based polymers have been studied.Here, we demonstrate that palladium atoms can be effectively isolated on other carbon nitride scaffolds including linear melem oligomers and poly(triazine/heptazine imides). Increased metal uptake was linked to the larger cavity size and the presence of chloride ions in the polyimide structures. Changing the host structure leads to significant variation in the average oxidation state of the metal, which can be tuned by exchange of the ionic species as evidenced by X-ray photoelectron spectroscopy and supported by density functional theory. Evaluation in the semi-hydrogenation of 2-methyl-3-butyn-2-ol reveals an inverse correlation between the activity and the degree of oxidation of palladium, with oligomers exhibiting the highest activity. These findings provide new mechanistic insights into the influence of the carbon nitride structure on metal stabilization.Zupeng Chen Evgeniya Vorobyeva Sharon Mitchell Edvin Fako Núria López Sean M.Collins Rowan K.Leary Paul A.Midgley Roland Hauert Javier Pérez-Ramírez 2018National Science Review2018,5,5:4
4Functional magnetic resonance imaging and the brain: A brief review显示文摘Functional magnetic resonance imaging(fMRI) is em-ployed in many behavior analysis studies, with blood oxygen level dependent-(BOLD-) contrast imaging being the main method used to generate images. The use of BOLD-contrast imaging in f MRI has been refined over the years, for example, the inclusion of a spin echo pulse and increased magnetic strength were shown to produce better recorded images. Taking careful precautions to control variables during measurement, comparisons between different specimen groups can be illustrated by f MRI imaging using both quantitative and qualitative methods. Differences have been observed in comparisons of active and resting, developing and aging, and defective and damaged brains in various studies. However, cognitive studies using f MRI still face a number of challenges in interpretation that can only be overcome by imaging large numbers of samples. Furthermore, f MRI studies of brain cancer, lesions and other brain pathologies of both humans and animals are still to be explored.Maggie SM Chow Sharon L Wu Sarah E Webb Katie Gluskin DT Yew 2017World Journal of Radiology2017,9,1:4
5Thrombolysis of stroke mimics via telestroke显示文摘Background The rate of intravenous tissue plasminogen activator(IVtPA)administered to stroke mimics(SM)occurs in 24%-44%of telestroke series.Methods We reviewed 270 suspected acute ischaemic stroke(AIS)patients who were evaluated by telestroke and received IVtPA from 1 July 2016 to 30 September 2017 at our academic comprehensive stroke centre.Results Among 270 AIS patients who received IVtPA via telestroke,64(23.7%)were diagnosed with SM.Compared with patients who had a stroke,the SM group was younger(mean age 56.4 vs 68.2,p<0.0001),more likely to be female(60.9%vs 45.6%,p=0.0324)and had longer door-to needle times(85.3 vs 69.9,p=0.0008).The most common SM diagnoses were migraine 26(40.6%),conversion disorder 12(18.8%),encephalopathy 7(10.9%)and unmasking(9.4%).Among the SM,migraine and conversion disorder were younger compared with the other subgroups(p<0.001).Functional exam elements were noted more frequently in conversion disorder(66.7%)and migraine(34.6%),but rare in other diagnoses(p=0.006).Among the SM,23(35.9%)had a history of a prior similar episodes,and 15(23.4%)had a history of more than 5 spells.Conclusions In our telestroke programme,23.7%of those administered thrombolysis had a final diagnosis of SM.Vivien H Lee Ravyn Howell Randheer Yadav Sharon Heaton Karen L Wiles Sushil Lakhani 2022Stroke & Vascular Neurology2022,7,3:2

7阿片类药物替代疗法:安全性和滥用倾向的比较研究显示文摘阿片类药物维持疗法是治疗阿片、海洛因和阿片类制剂依赖的有效方法。美沙酮和丁丙诺啡是世界范围内最常用于替代治疗的阿片类药物,纳曲酮作为一种阿片受体的拮抗剂用于阻断治疗。研究数据显示维持疗法比脱毒疗法疗效更好,但是,存在长期用药剂量的安全性问题,包括对药物的直接反应和滥用风险。对美沙酮和丁丙诺啡(单独使用或与纳曲酮合用)的研究揭示了剂量与效应的关系,以及最佳的用药方案。研究数据提示,在呼吸抑制(过量)和对心血管的直接作用方面丁丙诺啡较美沙酮风险更低。丁丙诺啡,作为一种部分激动剂,可能比美沙酮或者海洛因等完全激动剂的滥用倾向更小。本文提供的数据说明在阿片依赖的个体上丁丙诺啡的滥用风险较美沙酮的更低。最近的数据提示,在阿片依赖和非依赖的使用者中,丁丙诺啡/纳曲酮合用的滥用潜力低于丁丙诺啡单独使用。Sharon L WALSH 2009中国药物依赖性杂志2009,18,4:2
