Objective To systematically evaluate the effectiveness and safety of China-made omeprazole in treating acute non-variceal upper gastrointestinal bleeding. Methods Such databases as PubMed, MEDLINE, Springer, The Cochrane Library, CNKI, VIP, CBM and WanFang data were searched to collect the randomized controlled trials (RCTs) about China-made omeprazole in treating acute non-variceal upper gastrointestinal bleeding, and the references of included studies were also retrieved. The retrieval time was from inception to December 2012. Two reviewers independently screened the literature according to the inclusion and exclusion criteria, extracted the data, and assessed the quality, and then the meta-analysis was conducted by using RevMan 5.1 software. Results A total of 11 RCTs were included. Among all 1 075 patients, 544 were in the treatment group, while the other 531 were in the control group. The results of meta-analysis showed that, there were no significant differences in the total effective rate (OR=0.68, 95%CI 0.35 to 1.33, P=0.26) and safety (RR=1.33, 95%CI 0.45 to 3.91, P=0.96) between the China-made omeprazole and imported omeprazole. Conclusion China-made omeprazole is effective and safe in treating acute non-variceal upper gastrointestinal bleeding in comparison with the imported omeprazole.
目的 探討酶聯免疫吸附試驗(ELISA)檢測血清甲胎蛋白異質體(AFP-L3)含量對原發性肝癌（PLC）的診斷價值。 方法 選擇2011年3月－11月門診或住院的137例患者臨床檢測甲胎蛋白(AFP)為陽性的肝病患者血清，應用上海逸峰生物科技有限公司提供的ELISA法AFP-L3檢測試劑盒檢測AFP-L3濃度，137例中男98例，女39例，年齡28～77歲。其中PLC 92例，良性肝病45例，后者包括肝硬化37例、慢性肝炎8例。分析PLC組與良性肝病組AFP-L3濃度差異，運用受試者工作特征曲線(ROC)分析AFP-L3含量在PLC鑒別診斷中的價值。 結果 PLC組AFP-L3濃度[（109.04 ± 62.51）ng/mL]明顯高于良性肝病組[（25.96 ± 49.43）ng/mL，兩組差異有統計學意義（t=8.28 ，P＜0.001）。ROC分析結果顯示，曲線下面積為0.819，以AFP-L3濃度37.89 ng/mL為臨界值，分析92例PLC患者與45例良性肝病患者AFP-L3濃度異常的靈敏度為83.69%，特異度為88.88%，陽性預測值為93.90%（77/82），陰性預測值為72.72%（40/55），診斷準確度為85.40%。 結論 應用簡便快速的ELISA法檢測AFP-L3濃度在PLC與良性肝病鑒別診斷中具有較高的臨床價值，便于臨床推廣。
