Thrombosis and thromboembolism: Brighton collaboration case definition and guidelines for data collection,analysis, and presentation of immunization safety data

This is a Brighton Collaboration case definition of thrombosis and thromboembolism to be used in the evaluation of adverse events following immunization, and for epidemiologic studies for the assessment of background incidence or hypothesis testing. The case definition was developed by a group of experts convened by the Coalition for Epidemic Preparedness Innovations (CEPI) in the context of active development of SARS-CoV-2 vaccines. The case definition format of the Brighton Collaboration was followed to develop a consensus definition and defined levels of certainty, after an exhaustive review of the literature and expert consultation. The document underwent peer review by the Brighton Collaboration Network and by selected expert reviewers prior to submission.     

经导管局部溶栓治疗髂-股静脉血栓:58例回顾性分析

目的　探讨经导管局部溶栓治疗髂 股静脉血栓的效果及临床应用中的有关问题。资料与方法　对 5 8例髂 股静脉血栓形成患者 (病程 <4周 4 5例 ,>4周 13例 ) ,采取经导管血栓局部灌注尿激酶 ,尿激酶先团注2 5 0 0 0 0U ,然后以 12 5 0 0 0～ 15 0 0 0 0U/h持续灌注。结果　全组溶栓治疗时间 4～ 5 6h ,平均 36h ,尿激酶用量75 0 0 0 0～ 72 5 0 0 0 0U ,平均 4 70 0 0 0 0U。阻塞段完全开通 (残存狭窄率 <30 % )者 30例 ,部分开通者 2 3例 ,无效 5例 ,有效率达 91.4 %。对残存狭窄率 >30 %的 2 3例 ,14例行经皮球囊血管成形术 (PTA)治疗 ,9例行PTA及内支架治疗。 6例溶栓前放置下腔静脉过滤器。本组无严重并发症及肺栓塞发生。结论　经导管血栓局部灌注尿激酶是治疗髂 股静脉血栓的安全、有效方法。溶栓术后继续肝素全身抗凝治疗可增强溶栓疗效     

Alcohol and Platelet Function

Epidemiological studies have shown that moderate consumption of alcoholic beverages is inversely related to the incidence of the complications of coronary artery disease. The protective effect of ethanol may be partially attributable to an inhibitory effect of ethanol on platelets. This article summarizes the experimental observations that ethanol inhibits platelet responses to specific physiological agonists. In alcoholics, various platelet defects have been observed, but these may be influenced by metabolic factors rather than the presence of ethanol alone. The acute effects of ethanol on platelet functions both in vivo and ex vivo will be reviewed. Evidence will be presented demonstrating that ethanol added acutely in vitro inhibits phospholipase A₂ in stimulated platelets. The interaction of ethanol with other signal transduction pathways will also be discussed.     

可控性丝线留置术治疗体表难治性海绵状静脉畸形的实验及临床研究

目的研究可控性丝线的致栓效果及其治疗体表难治性海绵状静脉畸形的初步疗效。方法将丝线一端留置于不同管腔大小的静脉内,另一端挂于血管壁埋于皮下,实现其可控性,用经过不同处置的丝线,分别留置于兔耳缘静脉、股静脉,观察其引起血管栓塞的效果。选择致栓效果较好的丝线组,用于临床治疗难治性体表海绵状静脉畸形的患者。结果几种经不同处置的丝线,均能不同程度地起到闭塞血管的作用,对于管腔稍大,血流较快的静脉(兔股静脉),浸泡丝裂霉素并打结的丝线组,致栓效果最好;临床初步应用证实,可控性丝线治疗体表难治性静脉畸形,安全有效。结论可控性丝线静脉内留置术,是一种安全、有效、损伤小、操作简便的治疗体表难治性海绵状静脉畸形的新方法。

中西医结合治疗急性动脉栓塞过程中甲状腺激素测定的临床意义

目的：探讨甲状腺激素水平在急性动脉栓塞中中西医结合治疗过程中的变化规律及其临床意义。方法：利用放射免疫分析法对４０例本病患者及３０例健康对照组进行血清甲状腺激素测定，观察中西医结合治疗前后的变化，结果；４０例病人均存在在低Ｔ３、低Ｔ４和高ｒＴ３血症，且以重症病人最明显，Ｔ３水平低于０．５ｎｍｏｌ／Ｌ者病情危重，Ｔ４低于５０ｎｍｏｌ／Ｌ者预后不良；低Ｔ３、低Ｔ４和高ｒＴ３血症均随中西医结合有效治疗后     

抗磷脂抗体对妊娠的影响

自身免疫性疾病或免疫功能异常影响妊娠，在自身免疫疾病中，抗磷脂综合征（antiphospholipid syndrome APS）占了一定比例。本文就抗磷脂抗体的性质进行详细阐述。血栓形成是APS的主要病理基础和突出临床表现，随着研究深入，APA对早孕期滋养细胞的影响越来越受到重视，而APA导致不良妊娠结局的作用机制，目前仍有争论。本文还介绍了APS最新的治疗进展，为今后的APS发病机制研究及临床治疗带来更多的启示。
