12019新型冠状病毒基因组特征和流行病学:病毒起源和受体结合的意义显示文摘研究者对来自9例新型冠状病毒肺炎住院患者的支气管肺泡灌洗液样本和培养的分离株进行了下一代测序。从这些个体中获得了严重急性呼吸综合征-冠状病毒2(severe acute respiratory syndrome-coronavirus 2,SARS-CoV-2)的完整和部分基因组序列。利用Sanger测序连接病毒重叠群以获得全长基因组,cDNA末端快速扩增确定终端区。对这些SARSCoV-2基因组和其他冠状病毒基因组进行了系统进化分析,以确定该病毒的进化史并有助于推断其可能的起源。刘青(译) 刘莉(审校) Lu R Zhao X Li J Niu P Yang B Wu H Wang W Song H Huang B Zhu N Bi Y Ma X Zhan F Wang L Hu T Zhou H Hu Z Zhou W Zhao L Chen J Meng Y Wang J Lin Y Yuan J Xie Z Ma J Liu WJ Wang D Xu W Holmes EC Gao GF Wu G Chen W Shi W Tan W 2020中华高血压杂志2020,28,3:516
2美国国立老化研究所与阿尔茨海默病协会诊断指南写作组:阿尔茨海默病源性轻度认知障碍诊断标准推荐显示文摘美国国立老化研究所(NIA)和阿尔茨海默病协会(ADA)组织了一个工作组,负责阿尔茨海默病(AD)痴呆前症状阶段——即本文所称的AD源性轻度认知障碍(MCI)的诊断标准的制订及完善。该工作组制订了以下两套标准:(1)在缺乏相应条件进行先进影像技术及脑脊液检查时,医务人员适用的核心临床标准;(2)适用于包括临床试验在内的科学研究的研究标准。后者纳入了基于影像技术及脑脊液检查的生物标志物的应用。并根据所出现的生物标志物的性质,将最终MCI诊断的确定性程度分为4个级别。而要使生物标志物有效应用于诊断,并在社区医疗服务中规范使用,尚需做大量的工作。McKhann GM Knopman DS Chertkow H Hyman BT Jack CR Jr Kawas CH Klunk WE Koroshetz WJ Manly JJ Mayeux R Mohs RC Morris JC Rossor MN Schehens P Carrillo MC Thies B Weintraub S Phelps CH 贾建平(译) 陆璐(译) 张逸驰(译) 黄丽黄(译) 礼媛(译) 2012中华神经科杂志2012,45,5:51
3美国国立老化研究所与阿尔茨海默病协会诊断指南写作组:阿尔茨海默病痴呆诊断标准的推荐显示文摘由美国国立老化研究所(NIA)和阿尔茨海默病(AD)协会组织了一个工作组,负责修订1984年版AD痴呆的诊断标准。旨在确保修订后的标准具有足够的灵活性,既可供缺乏神经心理学测验、先进的影像技术和脑脊液检查措施的普通医务人员使用,也可供具备上述措施的科研、临床试验的专业研究者使用。新的标准广泛适用于各种原因的痴呆以及专门针对AD痴呆的标准,保留了1984年版标准中的“很可能的AD痴呆”的总体框架。在过去27年的经验基础上,工作组对临床诊断标准做了一些修改,保留了“可能的AD痴呆”的术语,但对其进行了更有针对性的重新定义。在科研用的“很可能的和可能的AD痴呆”的诊断标准中纳入了生物标志物证据。AD痴呆的核心临床标准仍将是临床实践中诊断的基础,但用生物标志物证据来提高AD痴呆诊断的病理生理学特异性也被人们寄予厚望。要实现AD痴呆的生物标志物诊断,还有许多工作摆在面前。McKhann GM Knopman DS Chertkow H Hyman BT Jack CR Jr Kawas CH Klunk WE Koroshetz WJ Manly J J Mayeux R Mohs RC Morris JC Rossor MN Scheltens P Carrillo MC Thies B Weintraub S Phelps CH 贾建平(译) 陆璐(译) 张逸驰(译) 黄丽(译) 韩阅(译) 2012中华神经科杂志2012,45,5:52

5AGNP精神科治疗药物监测共识指南:2011显示文摘治疗药物监测(Therapeutic drug monitoring,TDM),如通过定量测定血清或血浆药物浓度指导用药剂量优化,已经成为对患者进行精神药物治疗的很有价值的工具。在患者用药依从性难以判断、药物耐受性不佳、治疗剂量下无效以及可能存在药代动力学药物-药物相互作用等情况下,测定药物浓度是很有用的。在精神科,有可能明显获益于TDM的主要患者群体包括儿童、孕妇、老年患者、智力障碍患者、涉及司法的患者、已知或怀疑携带药代动力学相关基因变异的患者,以及合并躯体疾病影响药代动力学的患者。然而,只有将TDM充分整合到临床治疗过程中去,才能发挥其优化药物治疗的潜在优势。为了促进TDM的合理应用,神经精神药理学与药物精神病学协会(Arbeitsgemeinschaft für Neuropsychopharmakologie und Pharmakopsychiatrie,AGNP)的TDM专家组在2004年发表了精神药物治疗药物监测指南。之后,随着知识不断更新,又有许多可能需要进行TDM的新药上市。因此,本次更新将神经精神药物的种类扩展到了128种,并将其TDM必要性划分为从'强烈推荐'到'可能有用'的四个等级。经过大量细致且全面的文献检索与分门别类的汇总整理,将基于循证医学理念的'治疗参考浓度范围'和'剂量相关参考浓度范围'呈现给大家。本共识指南引入了'实验室警戒浓度'的新概念,即实验室需要马上告知治疗医生的药物浓度上限。本共识指南还给出了诸如药物作为细胞色素P450酶的底物和抑制剂的性质,代谢物与母药浓度比值的常见范围,以及与结果解释相关的内容,还提供了何时将TDM与遗传药理学检测相结合的建议。遵循本指南,有助于改善许多患者精神药物治疗的效果,特别是那些存在药代动力学异常的患者。TDM是一门交叉学科,有时针对看起来不一致的数据,需要多学科坦诚地讨论,只有这样,患者才能从这种合作中获益。Hiemke C Baumann P Bergemann N Conca A Dietmaier O Egberts K Fric M Gerlach M Greiner C Gründer G Haen E Havemann-Reinecke U Jaquenoud Sirot E Kirchherr H Laux G Lutz UC Messer T Müller MJ Pfuhlmann B Rambeck B Riederer P Schoppek B Stingl J Uhr M Ulrich S Waschgler R Zernig G 李文标(译) 果伟(译) 阮灿军(译) 贺静(译) 汤宜朗(审校) 王传跃(审校) 2016实用药物与临床2016,19,10:37
6最新AD研究用诊断标准:IWG-2标准显示文摘在过去的8年中,国际工作组织(IWG)和美国国立老化研究院-阿尔茨海默协会(NIA-AA)建立了阿尔茨海默病(AD)诊断标准,它能更好地定义AD的临床表型,整合了生物标记物于诊断流程中,并覆盖了疾病的全程。本意见书充分地权衡了IWG标准的优缺点,建议改进诊断框架。依据这些改进,AD的诊断变得简单,只要有恰当的AD临床表型(典型或不典型)和与AD的病理相一致的病理生理学生物标志物出现。我们认为疾病的下游的定位性生物标志,如容积性磁共振成像(MRI)和氟脱氧葡萄糖-正电子发射型计算机断层成像(FDG-PET)等,适合更好地测量和监测疾病过程。本文还详述了非典型性AD、混合性AD和AD临床前期的特异诊断标准。陈刚 曹雯炜 俞羚 糜建华 Dubois B Feldman HH Jacova C Hampel H Molinuevo JL Blennow K DeK osky ST Gauthier S Selkoe D Bateman R Cappa S Crutch S Engelborghs S Frisoni GB Fox NC Galasko D Habert MO Jicha GA Nordberg A Pasquier F Rabinovici G Robert P Rowe C Salloway S Sarazin M Epelbaum S de Souza LC Vellas B Visser PJ Schneider L Stern Y Scheltens P Cummings JL 2014神经病学与神经康复学杂志2014,11,3:31

9一项中断时间序列研究与集群随机试验:减少耐药细菌在重症监护室中定植和传播的干预措施显示文摘背景 重症监护室(ICU)是耐药细菌传播的高危科室,在设置标准预防措施时缺乏对"全面筛查和隔离携带或感染耐药细菌者"效果评估的对照研究,本研究评估此干预措施对减少ICU中耐药细菌的定植与传播的效果.曾翠 吴安华 Derde L P G Cooper B S Goossens H 2014中国感染控制杂志2014,13,1:23
10The ReaxFF reactive force-field: development, applications and future directions显示文摘The reactive force-field(ReaxFF)interatomic potential is a powerful computational tool for exploring,developing and optimizing material properties.Methods based on the principles of quantum mechanics(QM),while offering valuable theoretical guidance at the electronic level,are often too computationally intense for simulations that consider the full dynamic evolution of a system.Alternatively,empirical interatomic potentials that are based on classical principles require significantly fewer computational resources,which enables simulations to better describe dynamic processes over longer timeframes and on larger scales.Such methods,however,typically require a predefined connectivity between atoms,precluding simulations that involve reactive events.The ReaxFF method was developed to help bridge this gap.Approaching the gap from the classical side,ReaxFF casts the empirical interatomic potential within a bond-order formalism,thus implicitly describing chemical bonding without expensive QM calculations.This article provides an overview of the development,application,and future directions of the ReaxFF method.Thomas P Senftle Sungwook Hong Md Mahbubul Islam Sudhir B Kylasa Yuanxia Zheng Yun Kyung Shin Chad Junkermeier Roman Engel-Herbert Michael J Janik Hasan Metin Aktulga Toon Verstraelen Ananth Grama Adri CT van Duin 2016npj Computational Materials2016,,1:22

15Approach to the endoscopic resection of duodenal lesions显示文摘Duodenal polyps or lesions are uncommonly found on upper endoscopy. Duodenal lesions can be categorized as subepithelial or mucosally-based, and the type of lesion often dictates the work-up and possible therapeutic options. Subepithelial lesions that can arise in the duodenum include lipomas, gastrointestinal stromal tumors, and carcinoids. Endoscopic ultrasonography with fine needle aspiration is useful in the characterization and diagnosis of subepithelial lesions. Duodenal gastrointestinal stromal tumors and large or multifocal carcinoids are best managed by surgical resection. Brunner's gland tumors, solitary Peutz-Jeghers polyps, and non-ampullary and ampullary adenomas are mucosally-based duodenal lesions, which can require removal and are typically amenable to endoscopic resection. Several anatomic characteristics of the duodenum make endoscopic resection of duodenal lesions challenging. However, advanced endoscopic techniques exist that enable the resection of large mucosally-based duodenal lesions. Endoscopic papillectomy is not without risk, but this procedure can effectively resect ampullary adenomas and allows patients to avoid surgery, which typically involves pancreaticoduodenectomy. Endoscopic mucosal resection and its variations(such as cap-assisted, cap-band-assisted, and underwater techniques) enable the safe and effective resection of most duodenal adenomas. Endoscopic submucosal dissection is possible but very difficult to safely perform in the duodenum.Jonathan P Gaspar Edward B Stelow Andrew Y Wang 2016World Journal of Gastroenterology2016,22,2:17
16Antioxidant activities of Indigofera cassioides Rottl.Ex.DC.using various in vitro assay models显示文摘Objective:To evaluate the antioxidant potential of methanolic leaf extract of Indigofera cassioides(MEIC) using various in vilro antioxidant assay systems.Methods:Antioxidant and free radical scavenging activity of MEIC was assayed by using different in vitro models like ABTS, DPPH,nitric oxide,superoxide,hydrogen peroxide and hydroxyl radical.Reductive ability of the extract was tested by the complex formation with potassium ferricyanide.Further total phenol and flavonoid contents of the crude extract were also determined.Rutin and ascorbic acid were used as standards.Results:MEIC exhibited potent and concentration dependent free radical scavenging activity in all the tested models.Reductive ability was also found to increase with increase in MEIC concentration.Total phenol and flavonoid content determination showed that the extract is rich in phenols and flavonoids.Conclusions:All the results of the in vitro antioxidant assays reveal potent antioxidant and free radical scavenging activity of the leaves of Indigofera cassioides,equivalent to that of standard ascorbic acid and rutin.This potent antioxidant activity may be attributed to its high phenolic and flavonoid contents.R Senthil Kumar B Rajkapoor P Perumal 2012Asian Pacific Journal of Tropical Biomedicine2012,2,4:15
17内侧固定平台单髁置换术后的冠状面下肢力线是翻修的影响因素显示文摘膝关节单髁置换术(unicompartmental knee arthroplasty,UKA)后患者冠状面的下肢力线被认为是影响手术长期疗效的一个重要因素,但关于最佳的UKA术后下肢力线还没有形成明确共识。一些研究主张术后下肢力线应保持在中立位,而另一些研究认为即使术后下肢力线存在10°的内翻也可获得良好的临床效果。Sean E Slaven John P Cody Robert A Sershon Henry Ho Robert H Hopper Jr Kevin B Fricka 李亚坤(整理) 张民(整理) 2020实用骨科杂志2020,26,12:15
18在血压控制不良的高血压患者中使用数字化干预的家庭和在线血压管理:随机对照试验显示文摘HOME BP试验(The home and online management and evaluation of blood pressure)的目的是评估在初级预防中结合自我监测和自我管理的数字化干预在高血压管理中的作用。研究者纳入英国76个治疗中心经过治疗但血压控制不好(>140/90 mm Hg, 1 mm Hg=0.133 kPa)并能上网的患者622例,进行自动确定主要终点的公开随机对照试验。McMa-nus RJ Little P Stuart B Morton K Raftery J Kelly J Bradbury K Zhang J Zhu S Murray E May CR Mair FS Michie S Smith P Band R Ogburn E AllenJ Rice C Nut-tall J Williams B Yardley L 陈嘉睿(译) 叶鹏(审校) 2021中华高血压杂志2021,29,5:15
19我国农村居民的红细胞脂肪酸、血浆脂质与心血管疾病显示文摘对我国49个县的心血管疾病(CVD,包括冠心病、高血压心脏病和脑卒中)死亡率和4900例35~64岁成年男女的膳食进行了调查,并测定了血浆脂质[总胆固醇(TC)、高密度脂蛋白胆固醇(HDL-C)和甘油三酸酯(TG)]的含量,结果指出:1.和西方国家人群比较,我国农民血浆TC、TG、HDL-C和依此计算而得的LDL-C水平较低,而HDL-C/TC比值较高,CVD死亡率也较西方国家的为低。2.在TC、LDL-C与CVD死亡率之间无相关,但在红细胞油酸水平与CVD死亡率间有显著负相关。3.红细胞油酸水平与血浆TC含量间无相关,而与红细胞花生四烯酸水平呈显著负相关。指出油酸对CVD死亡率的影响有可能是通过另一条途径,即减低血小板的聚集作用。4.我国的CVD死亡率呈现明显的地区性分布,即南方低于北方。其分布与红细胞油酸含量,及大米摄取量的地区性分布呈明显的负关系。5.为解释CVD死亡率与红细胞油酸的负关系,本文提出了油酸可能置换了血小板膜磷脂中多不饱和脂肪酸的设想,但对大米保护CVD的作用则尚需有更多的调查和研究数据才能确证之。范文洵 Parker R Parpia B 屈荫生 Cassano P Crawford M Leyton J 田巧珍 黎均耀 陈君石 Campbell C 1992营养学报1992,14,1:15
20Biliary strictures complicating living donor liver transplantation:Problems,novel insights and solutions显示文摘Biliary stricture complicating living donor liver transplantation(LDLT) is a relatively common complication, occurring in most transplant centres across the world. Cases of biliary strictures are more common in LDLT than in deceased donor liver transplantation. Endoscopic management is the mainstay for biliary strictures complicating LDLT and includes endoscopic retrograde cholangiography, sphincterotomy and stent placement(with or without balloon dilatation). The efficacy and safety profiles as well as outcomes of endoscopic management of biliary strictures complicating LDLT is an area that needs to be viewed in isolation, owing to its unique set of problems and attending complications; as such, it merits a tailored approach, which is yet to be well established. The diagnostic criteria applied to these strictures are not uniform and are over-reliant on imaging studies showing an anastomotic narrowing. It has to be kept in mind that in the setting of LDLT, a subjective anastomotic narrowing is present in most cases due to a mismatch in ductal diameters. However, whether this narrowing results in a functionally significant narrowing is a question that needs further study. In addition, wide variation in the endotherapy protocols practised in most centres makes it difficult to interpret the results and hampers our understanding of this topic. The outcome definition for endotherapy is also heterogenous and needs to be standardised to allow for comparison of data in this regard and establish a clinical practice guideline. There have been multiple studies in this area in the last 2 years, with novel findings that have provided solutions to some of these issues. This review endeavours to incorporate these new findings into the wider understanding of endotherapy for biliary strictures complicating LDLT, with specific emphasis on diagnosis of strictures in the LDLT setting, endotherapy protocols and outcome definitions. An attempt is made to present the best management options currently available as well as directions for future research in the area.Harshavardhan B Rao Arjun Prakash Surendran Sudhindran Rama P Venu 2018World Journal of Gastroenterology2018,24,19:14
