目的:系统评价槐杞黄颗粒联合西药治疗儿童哮喘的有效性及安全性。方法:检索中文数据库(中国知网、万方数据库、维普数据库、中国生物医学文献数据库)和英文数据库(PubMed、EMbase、Cochrane Library、Web of Science),检索时间为建库至...目的:系统评价槐杞黄颗粒联合西药治疗儿童哮喘的有效性及安全性。方法:检索中文数据库(中国知网、万方数据库、维普数据库、中国生物医学文献数据库)和英文数据库(PubMed、EMbase、Cochrane Library、Web of Science),检索时间为建库至2019年11月。由2名研究者按照预先设定的纳排标准独立筛选槐杞黄颗粒联合西医治疗儿童哮喘的随机对照试验(RCTs),并进行数据提取及质量评价。使用Revman 5.3软件进行Meta分析。结果:共纳入16个研究,1814例患者,试验组914例,对照组900例。Meta分析结果显示,槐杞黄颗粒联合西药治疗儿童哮喘可提高总有效率[RR=1.22,95%CI(1.17,1.28),P<0.000,01];增加1 s用力呼气量(FEV1)[SMD=1.39,95%CI(0.77,2.01),P<0.000,1];增加用力肺活量(FVC)[MD=0.64,95%CI(0.44,0.83),P<0.000,01];提高1 s用力呼气量占用力肺活量百分比(FEV1/FVC)[MD=10.08,95%CI(9.07,11.08),P<0.000,01];降低IgE水平[SMD=-0.54,95%CI(-0.71,-0.38),P<0.000,01];提高干扰素γ(IFN-γ)水平[SMD=0.85,95%CI(0.72,0.98),P<0.000,01]。纳入研究中报告的不良反应均为轻度不良反应。结论:槐杞黄颗粒辅助治疗儿童哮喘具有一定的疗效,可提高总有效率,改善肺功能,纠正免疫失衡,且无明显不良反应。但本研究纳入文献质量较低,仍需设计严谨的多中心、大样本的RCT研究予以验证。展开更多
