摘要 目的探讨中国人群四氢叶酸还原酶(MTHFR)基因C677T多态性与重症抑郁症(MDD)的关系。方法对符合条件的研究进行meta分析,分别以1168例MDD患者和1378例对照人群等位基因和基因型频率分布的OR值为统计量,采用固定或随机效应模型进行合并分析,并进行偏倚评估。结果9篇文献符合条件纳入研究,入选文献无明显发表偏倚。数据合并结果显示:T/C等位基因、TT基因型合并的OR值(95%C1)分别为1.45(1.12-1.88)和1.37(0.98-1.92)。其次发现重症抑郁症患者组中TT基因型HAMD-17评分均高于CT、CC基因型,差异有统计学意义。且血清半胱氨酸(HCY)的浓度依次从cc、CT、TT基因型之间升高,两组比较均有显著性差异。结论MTHFR C677T基因多态性与重症抑郁症发病风险、严重程度及血清半胱氨酸浓度具有相关性。
