Efficacy and safety of transjugular intrahepatic portosystemic shunt (TIPS) created using covered stents of different diameters: A systematic review and meta-analysis

PurposeThe purpose of this study was to make a systematic review and meta-analysis to determine the stent diameter (8 mm vs. 10 mm) that conveys better safety and clinical efficacy for transjugular intrahepatic portosystemic shunt (TIPS).Materials and methodsFour databases were used to identify clinical trials published from inception until March 2020. Data were extracted to estimate and compare one-year and three-year overall survivals, hepatic encephalopathy, variceal rebleeding, and shunt dysfunction rates between patients with 8 mm covered stents and those with 10 mm covered stents.ResultsFive eligible studies were selected, which included 489 patients (316 men, 173 women). The 8 mm covered stent group had higher efficacy regarding one-year or three-year overall survival (odds ratio [OR], 2.88; P = 0.003) and (OR, 1.81; P = 0.04) and lower hepatic encephalopathy (OR, 0.69; P = 0.04) compared with 10 mm covered stent group. There were no significant differences in variceal rebleeding rate (OR 0.80; P = 0.67). However, shunt dysfunction was lower in 10 mm covered stent group (OR, 2.26; P = 0.003).ConclusionsOur results suggest that the use of 8 mm covered stents should be preferred to that of 10 mm covered stents for TIPS placement when portal pressure is frequently monitored.     

比较手术夹闭和介入栓塞治疗颅内未破裂动脉瘤安全性和有效性的Meta分析

目的比较手术夹闭和介入栓塞治疗颅内未破裂动脉瘤的安全性和有效性。方法计算机检索1990至2018年颅内未破裂动脉瘤的所有临床对照研究。两名研究员分别纳入研究、提取数据、质量评价并应用Rev Man5. 0软件进行数据处理。结果最终纳入21篇文献,病例数109114例。Meta分析结果提示:手术夹闭组动脉瘤闭塞率为88. 2%,平均住院时间7. 7天,均高于介入栓塞组的65. 3%和4. 1天,P 0. 05。介入组患者的短期死亡率和致残率分别为0. 61%和2. 1%,均低于手术组的1. 27%和4. 7%,P 0. 05。介入组患者的1年期死亡率和致残率(2. 5%、2. 5%)均与手术组(2. 2%、1. 8%)无明显差异,P 0. 05。漏斗图未发现发表偏倚。敏感性分析结果一致。结论介入栓塞相比于手术夹闭可缩短患者的住院时间,降低患者的短期不良预后发生率。但是动脉瘤的闭塞率较低,1年期预后与手术夹闭无明显差异。据此推测手术夹闭患者的长期预后可能要好于介入栓塞,手术夹闭更适合于年轻患者。     

儿科诊断性X线扫描家属知情与接受现状调查

目的:了解建德市基层医院儿科门诊进行X线扫描治疗中,家属对X射线检查的知情同意与接受现状。方法:随机抽取建德市属3家公立综合性医院共60位接受X线扫描的儿童患者家属为调查对象,发放自制调查问卷并统计分析。结果:55位(91.67%)患者表示治疗前主治医生只告知了X射线是诊断性检查,没有具体告知X射线的危害性;18位(30%)的患者家属不清楚辐射会对人体有损害,42位(70%)不清楚或不注意辐射警示标志,更不会主动要求防护措施,学历水平较高者及有从事医务工作背景者接受X射线检查的为12人(20%),明显低于学历水平低者或没有从事医务工作背景者的46人(76.67%),不知可否接受的有2人(3.33%)(P<0.001)。结论:基层医院儿科诊断性X射线扫描前的知情同意告知仍需加强,儿科放射检查偏多,应避免并加强宣传和教育。     

恶性肿瘤靶向药物治疗后口腔黏膜炎中西医研究进展

查阅近10 年中西医防治恶性肿瘤靶向药物治疗后口腔黏膜炎的相关文献，对其中西医发病机制、防治方法展开系统整理与分析。本病的发病机制尚未明确，现代医学认为可能与靶向药物治疗的作用机制相关，防治措施以口腔护理、支持性治疗为主，皮质类固醇激素对依维莫司相关性口腔炎疗效显著。靶向药物治疗后口腔黏膜炎属中医口疮、口糜等范畴，以脏腑功能失调、火热上挠口舌为主要病机，病位以心、脾、肾为主，治则上以清热泻火、调理脏腑阴阳为主，可分为清热解毒、清心泻脾、清热祛湿、养阴清热、健脾泻火五种治法。扶正抗癌法联合靶向药物使用可预防口腔黏膜炎的发生。     

A comparison of the relationships between psychosocial factors,occupational strain,and work ability among 4 ethnic teacher groups in China

The present study compared the level of occupational strain and work ability among Han, Hui, Uygur, Hui, and Kazakh teachers, and explored ethnic differences based on the associations of psychosocial factors at work, occupational strain, and work ability. A cross-sectional survey was conducted among 2,941 teachers in primary and secondary schools in Xinjiang Province, China. Psychosocial factors, occupational strain, and work ability were measured using the Occupation Stress Inventory—Revised Edition (OSI-R) and Work Ability Index. Han and Hui teachers experienced reduced work ability compared with Uygur and Kazakh teachers, and this finding was caused, in part, by exposure to psychosocial factors at work. The vocational and psychological strains caused by these factors play an important role in reduced work ability among all ethnic teacher groups. The findings indicate the importance of taking action to reduce occupational strain for promoting teachers' work ability in multiethnic workplaces.     

层面递进法激光腔内剜除高危前列腺增生的治疗体会

目的探讨1 470 nm激光剜除治疗高危前列腺增生的手术技巧及临床效果。 方法回顾分析2018年6月至2018年9月中山大学附属第三医院泌尿外科采用1 470 nm激光治疗共89例高危前列腺增生患者的临床资料，年龄平均（68±3）岁，前列腺体积（57.4±2.6）ml。所有患者均采用"寻找层面，先易后难，剜切结合"的层面递进法思路行激光腔内前列腺剜除术，比较患者术中及术后情况。 结果89例均顺利完成手术，与术前相比，术后3个月患者最大尿流率明显增加，[（6.9±2.1） ml/s vs（19.8±3.6） ml/s]。国际前列腺症状评分显著好转，[（24.6±1.7） vs（8.0±1.2）]。术中无输血、无电切综合征、无直肠和膀胱穿孔病例，无输尿管损伤、大出血、心脑血管意外等严重并发症发生。 结论层面递进法激光剜除技术构想对于高危前列腺增生外科包膜层面的寻找、减少术后并发症有独到优势，且易于掌握，或可为业界同行提供一个新的思路。
