摘要 目的:运用Meta分析综合评价亚甲基四氢叶酸还原酶(MTHFR)C677T基因多态性与复发性自然流产的关系。方法:通过检索Pub Med、中国知网等中英文文献数据库,收集所有关于MTHFR C677T基因多态性与复发性自然流产相关的病例对照研究,提取所需数据应用Rev Man 5.3软件进行Meta分析。结果:共收入13篇文献,其中7篇中文相关文献和6篇英文文献。包括病例组1646例,对照组4072例。Meta分析结果表明:TT型发生复发性流产的风险比CC/CT高1.33倍[RR=1.33,95%CI=0.85~2.09],其中国内和国外人群TT型发生复发性流产的风险分别比CC/CT型高1.90倍[RR=1.90,95%CI=1.25~2.89]和0.58倍[RR=0.58,95%CI=0.22~1.49];TT型发生复发性流产的风险比含C等位基因型高1.40倍[RR=1.40,95%CI=0.81~2.40],其中国内和国外人群TT型发生复发性流产的风险分别比含C等位基因型高2.25倍[RR=2.25,95%CI=1.41~3.59]和0.48倍[RR=0.48,95%CI=0.48~1.55]。结论:MTHFR C677T基因多态性与复发性流产的易感性密切相关,但其病因关联性仍有待于在人群中进行大规模的研究加以论证。
