目的运用meta分析方法系统评价补肾方剂治疗男性不育症患者精子DNA损伤(SDF)的有效性和安全性。方法从中国知网、维普、万方、PubMed、Cochrane Library、Embase、Web of Science数据库中检索补肾方剂改善SDF的随机对照试验(RCT)研究,...目的运用meta分析方法系统评价补肾方剂治疗男性不育症患者精子DNA损伤(SDF)的有效性和安全性。方法从中国知网、维普、万方、PubMed、Cochrane Library、Embase、Web of Science数据库中检索补肾方剂改善SDF的随机对照试验(RCT)研究,对文献进行方法学质量评价,运用RevMan5.3.5软件进行meta分析,并对结局指标进行GRADE质量分级。结果共纳入17项RCT研究,涉及2164例男性患者。与西医常规治疗相比,补肾方剂能够显著改善男性不育症患者DNA碎片指数(DFI)(MD=-6.50,95%CI:-7.88~-5.11,P<0.01),提高配偶妊娠率(RR=2.11,95%CI:1.12~4.00,P=0.87)、精子总活率(MD=5.56,95%CI:4.39~6.74,P<0.01)、前向运动精子百分率(MD=6.82,95%CI:5.62~8.03,P<0.01)、精子浓度(MD=6.51,95%CI:3.81~9.21,P<0.01)和正常形态精子百分率(MD=1.26,95%CI:0.45~2.06,P<0.01),且补肾方剂不会增加不良反应的发生。结论低到中等质量证据表明,与西医常规治疗相比,补肾方剂在改善男性不育症患者DFI、精液参数、配偶妊娠率等方面具有一定优势,且安全性较好。展开更多
