生化汤加味促进剖宫产后子宫复旧随机对照试验的系统评价及Meta分析＊

目的 对生化汤加味促进剖宫产后子宫复旧的有效性与安全性进行系统评价，为其在临床应用提供循证医学证据。方法 检索中国生物医学文献数据库（CBM）、中国知网（CNKI）、万方资源数据库（WanFang）、维普期刊数据库（VIP）、Cochrane Library、PubMed、Web of Science等，检索时限为建库至2020年7月，选择生化汤加味促进剖宫产后子宫复旧的随机对照试验（RCT），采用Cochrane系统评价员手册提供的偏倚风险评估工具进行文献质量评价，应用RevMan5.3软件进行Meta分析。结果 共纳入12篇RCT文献，共计1804例剖宫产产妇；Meta分析结果显示，生化汤加味联合缩宫素组在产后第1、3、5天子宫底高度［MD = -0.75，95%CI（-1.35， -0.15），P < 0.00001；MD = -1.92，95%CI（-3.13， -0.72），P < 0.00001；MD = -1.92，95%CI（-3.79， -0.06），P < 0.00001］低于单用缩宫素组，联合用药组血性恶露时间［MD = -1.52，95%CI（-2.71，-0.34），P < 0.00001］和产后恶露持续时间［MD = -4.47，95%CI（-6.20，-2.75），P < 0.00001］均短于单用缩宫素组。结论 生化汤加味联合缩宫素与单用缩宫素比较，更能促进产后子宫复旧；不良反应少，报道的仅有4例出现轻微腹泻，安全性较高；但由于纳入文献质量较低，上述结论尚需更多的随机对照临床研究加以证实。     

Outcomes and risk management in type B aortic dissection patients with acute kidney injury: a concise review

PurposeType B aortic dissection is a rare but life-threatening disease. Thoracic endovascular aortic repair (TEVAR) was widely used for Type B aortic dissection patients in the last decade due to the lower mortality and morbidity compared with open chest surgical repair (OCSR). AKI in type B aortic dissection is a well-recognized complication and indicates poor short-term and long-term outcome. The objective of this concise review was to identify the risk factors and the impact of AKI on type B aortic dissection patients.Methods and resultsA literature search was performed using PubMed, Embase, MEDLINE, and Cochrane Library with the search terms ‘type B aortic dissection’ and ‘acute kidney injury’ (AKI), and all English-language literatures published in print or available online from inception through August 2020 were thoroughly reviewed. Studies that reported relative AKI risks and outcomes in type B aortic dissection patient were included. Major mechanisms of AKI in type B aortic dissection included renal hypoperfusion, inflammation response, and the use of contrast medium. Type B aortic dissection patients with AKI significantly had increased hospital stay duration, need of renal replacement therapy, and 30-d and 1-year mortality.ConclusionsAKI in type B aortic dissection is a well-recognized complication and associated with poor short-term and long-term outcome. Early identification of high-risk patients, early diagnosis of AKI, stabilization of the hemodynamic parameters, avoidance of nephrotoxic drugs, and optimization of the use of contrast agents are the major strategies for the reduction of AKI in type B aortic dissection patients.     

梅毒螺旋体血行播散机制的研究进展

【摘要】 梅毒是由梅毒螺旋体进入循环系统进行血行播散导致的多系统损害，但目前其全身播散的具体机制尚未完全明确。基于国内外的研究进展，本文从梅毒螺旋体黏附与细胞外基质降解、细胞间连接和细胞骨架系统破坏、血管生成、炎症细胞浸润等多方面探讨梅毒螺旋体血行播散的机制，为进一步研究提供理论基础。     

Optimize the management of urological tube-related emergencies during the coronavirus disease 2019 (COVID-19) pandemic

BackgroundTo introduce and determine the value of optimized strategies for the management of urological tube-related emergencies with increased incidence, complexity and operational risk during the global spread of coronavirus disease 2019 (COVID-19).MethodsAll emergent urological patients at Tongji Hospital, Wuhan, during the period of January 23 (the beginning of lockdown in Wuhan) to March 23, 2020, and the corresponding period in 2019 were recruited to form this study’s COVID-19 group and control group, respectively. Tongji Hospital has the most concentrated and strongest Chinese medical teams to treat the largest number of severe COVID-19 patients. Patients in the control group were routinely treated, while patients in the COVID-19 group were managed following the optimized principles and strategies. The case incidence for each type of tube-related emergency was recorded. Baseline characteristics and management outcomes (surgery time, secondary complex operation rate, readmission rate, COVID-19 infection rate) were analyzed and compared across the control and COVID-19 periods.ResultsThe total emergent urological patients during the COVID-19 period was 42, whereas during the control period, it was 124. The incidence of tube-related emergencies increased from 53% to 88% (P<0.001) during the COVID-19 period. In particular, the incidence of nephrostomy tube-related (31% vs. 15%, P=0.027) and single-J stent-related problems (19% vs. 6%, P=0.009) increased significantly. The mean surgery times across the two periods were comparable. The number of secondary complex operations increased from 12 (18%) to 14 (38%) (P=0.028) during the COVID 19-period. The number of 2-week postoperative readmission decreased from 10 (15%) to 1 (3%) (P=0.049). No participants contracted during the COVID-19 period.ConclusionsUrological tube-related emergencies have been found to have a higher incidence and require more complicated and dangerous operations during the COVID-19 pandemic. However, the optimized management strategies introduced in this study are efficient, and safe for both urologists and patients.

发达国家医学生器官捐献意愿研究现状的范围综述

目的了解发达国家医学生器官捐献意愿研究的目的、结果、障碍因素和解决对策。 方法以主题词和自由词联合的方式对PubMed、Web of Science、Ovid MEDLINE、Ovid EMBASE(Excerpta Medica)、EBSCOhost Complete和Cochrane Library等已发表文献数据库，以及灰色文献数据库York Centre for Reviews and Dissemination、Open Grey、ProQuest Dissertation and Theses和Mednar进行系统、全面地检索，并采用Arksey和O′Malley提出的范围综述框架进行文献资料整合。 结果共纳入17项发达国家医学生器官捐献意愿研究。研究背景主要为医学生未来对于公众器官捐献有着重要影响。研究结果表明，大多数医学生器官捐献意愿性良好，但不同亚组的研究结果不一；其最主要的障碍因素为医学生器官捐献相关知识的缺乏；解决对策主要为施予系统化、结构化和可评价的教育课程。 结论21世纪以来发达国家医学生器官捐献意愿研究方兴未艾，其研究的多层面、多角度以及揭示的问题、寻求的解决对策，可对我国现阶段医学生器官捐献的研究提供一定参考。     

腹腔镜经腹腹膜前疝修补术与开放式腹膜前疝修补术治疗股疝的疗效比较

目的比较腹腔镜经腹腹膜前疝修补术（TAPP）与开放式腹膜前疝修补术治疗股疝的手术结果和对生活质量的影响。 方法回顾性分析2014年1月至2019年12月新疆医科大学第一附属医院收治的58例股疝患者的临床资料，根据手术方式不同分为TAPP组和开放式腹膜前疝修补术组（开放组），TAPP组31例，开放组27例。比较两组手术指标，采用卡罗来纳舒适量表（CCS）评估并比较两组患者术前及术后1、6、12和24个月的生活质量。 结果TAPP组在手术时间、术中出血量、术后住院天数及术后并发症发生率等方面和开放组相比差异无统计学意义（P>0.05）；TAPP组在术后24 h疼痛视觉模拟评分及术后镇痛药使用率方面明显优于开放组（P<0.05）；TAPP组术后离床时间及术后首次进食时间长于开放组（P<0.05）；2组患者术后随访24个月，均无复发病例。两种术式均能有效改善患者术前的疼痛、运动受限及总体生活质量（P<0.05）；TAPP组患者术后1个月疼痛及总体生活质量优于开放组（P<0.05）。 结论TAPP与开放式腹膜前疝修补术均可有效治疗股疝。TAPP可作为无全身麻醉禁忌股疝患者的首选治疗方法。股疝的治疗应依据患者的自身情况和手术医师的技术掌握程度制定个体化治疗方案。
