OBJECTIVE:To systematically review the efficacy and safety of Deproteinised calf blood serum injection in the treatment of cerebral infarction,and to provide evidence-based reference for clinical treatment.METHODS:Retrieved from Co-chrane Library,EMBase,Medline,CBM,CJFD,VIP and Wanfan database,randomized controlled trials(RCT)about theeffica-cy and safety ofDeproteinised calf blood serum injection(test group)based on basic treatment(control group)in the treatment of cerebral infarction were collected.Meta-analysis was performed by using Rev Man 5.2 software after data extraction and quality eval-uation with Cochrane system evaluation manual 5.1.0.RESULTS:A total of 18 RCTs were included,involving 2 111 patients.Re-sults of Meta-analysis showed the total effective rate [OR=3.30,95%CI(2.48,4.39),P<0.001],National Institutes of Health Stroke Scale (NIHSS) score[MD=-1.47,95%CI(-2.06,-0.88),P<0.001] and activities of daily living(ADL) score[MD=9.09,95%CI(6.46,11.72),P<0.001] in test group were significantly better than control group,there were significant differences be-tween the 2 groups;and there was no obvious adverse reactions during treatment. CONCLUSIONS:Both efficacy and safety of De-proteinised calf blood serum injectionin the treatment of cerebral infarction are good.%目的：系统评价小牛血清去蛋白注射液治疗脑梗死的疗效与安全性，以为临床提供循证参考。方法：计算机检索Cochrane图书馆、EMBase、Medline、中国生物医学文献数据库、中国期刊全文数据库、中文科技期刊数据库和万方数据库，收集在基础治疗（对照组）上加用小牛血清去蛋白注射液（试验组）治疗脑梗死疗效与安全性的随机对照试验（RCT），对符合纳入标准的研究进行资料提取，并采用Cochrane系统评价手册5.1.0进行质量评价后，采用Rev man 5.2统计软件进行Meta分析。结果：共纳入18项RCT，合计2111例患者。Meta分析结果显示，试验组患者的总有效率[OR＝3.30，95％CI（2.48，4.39），P＜0.001]、国立卫生研究院卒中量表（NIHSS）评分[MD＝－1.47，95％CI（－2.06，－0.88），P＜0.001]、日常生活能力量表（ADL）评分[MD＝9.09，95％CI（6.46，11.72），P＜0.001]均显著优于对照组，差异均有统计学意义；两组患者治疗期间未出现明显不良反应。结论：小牛血清去蛋白注射液治疗脑梗死的疗效与安全性均较好。
