目的:对益生菌增效治疗幽门螺杆菌(Helicobacter pylori,H.pylori)感染的系统评价/Meta分析进行再评价研究.方法:计算机检索CBM、CNKI、Wanfang Data、VIP Data、the Cochrane library、PubMed、Embase数据库,收集关于益生菌增效治疗H.p...目的:对益生菌增效治疗幽门螺杆菌(Helicobacter pylori,H.pylori)感染的系统评价/Meta分析进行再评价研究.方法:计算机检索CBM、CNKI、Wanfang Data、VIP Data、the Cochrane library、PubMed、Embase数据库,收集关于益生菌增效治疗H.pylori感染的系统评价/Meta分析文章,检索时间均从建库至2014-10.由两位研究者按照纳入排除标准独立筛选文献、提取资料后,采用OQAQ(Overview Quality Assessment of Questionnaire)量表评价纳入研究质量,并采用GRADE(Grade o f R e c o m m e n d a t i o n,A s s e s s m e n t,Development,and Evaluation)系统进行证据质量分级.结果:共纳入11个相关Meta分析,11个研究均评价了益生菌增效治疗H.pylori的根除率及总不良反应发生率,其中3个研究详细评价了抗H.pylori具体不良反应发生率,OQAQ平均得分3.82分.GRADE系统的证据质量评价结果显示证据质量等级普遍较低.结论:当前益生菌增效治疗H.pylori感染具有一定的优势,但Meta分析的总体质量较差,证据水平较低,临床医生应根据实际情况进行循证决策.展开更多
目的:系统评价谷氨酰胺(Gln)对腹部手术后病人肠黏膜通透性的影响。方法:通过计算机检索中国学术期刊全文数据库(CNKI)、中国生物医学文献数据库(CBMdisc)、万方数据库和Pub Med数据库等的文献资料,评价纳入随机对照研究,应用Rev Man 5....目的:系统评价谷氨酰胺(Gln)对腹部手术后病人肠黏膜通透性的影响。方法:通过计算机检索中国学术期刊全文数据库(CNKI)、中国生物医学文献数据库(CBMdisc)、万方数据库和Pub Med数据库等的文献资料,评价纳入随机对照研究,应用Rev Man 5.2软件进行Meta分析。结果:经筛选共纳入9篇病例对照研究,累计421例受试者。结果显示,Gln可以降低腹部手术后病人肠黏膜乳果糖/甘露醇的比值[WMD=-0.05,95%CI(-0.09,-0.01)(P=0.01)],降低腹部手术后病人二胺氧化酶浓度[WMD=-1.60,95%CI(-1.89,-1.31)(P<0.01)],并有降低术后病人循环D-乳酸的趋势,但无显著性差异[WMD=-8.14,95%CI(-18.12,-1.84)(P=0.11)]。结论:Gln能有效地降低外科腹部手术病人术后肠黏膜通透性,降低二胺氧化酶浓度,目前证据不能充分肯定Gln对循环D-乳酸有影响。展开更多
