中国汉族人群基质金属蛋白酶9基因-1562C>T多态性与冠心病易感性的Meta分析

目的综合评价中国汉族人群基质金属蛋白酶9基因-1562C>T多态性与冠心病易感性相关。方法通过文献检索收集2010年12月以前完成或发表的中国汉族人群基质金属蛋白酶9基因-1562C>T多态性与冠心病相关性的病例对照研究,剔除不符合要求的文献,以漏斗图检验入选文献的偏倚,并根据各入选文献结果的同质性检验结果进行数据合并,计算总OR值,Meta分析采用Revman5.0及StatalO.0统计软件。结果共7篇文献符合条件纳入研究,入选文献无明显偏倚,Meta分析显示TT+CT基因型比CC基因型OR=1.47(95%CI为1.20～1.78,P=0.0001);T等位基因比C等位基因OR=1.41(95%CI为1.17～1.69,P=0.0002);CC基因型比CT+TT基因型OR=0.68(95%CI为0.55～0.82,P<0.0001);CT基因型比CC+TT基因型OR=1.45(95%CI为1.19～1.77,P=0.0002)。结论基质金属蛋白酶9基因-1562C>T多态性与中国汉族人群冠心病易感性相关,T等位基因可能是冠心病遗传危险因素。

Association of-1562C>T Polymorphism of Matrix Metalloprotein-9 Gene and Coronary Artery Disease in Chinese Han Population: a Meta-analysis

Aim Association between the-1562C>T single nueleotide polymorphisms of matrix metalloprotein-9 gene and the occurrence coronary artery disease in Chinese Han population was studied. Methods Case-control studies published before 31 Dec.2010 about the association of matrix metalloprotein-9 gene-1562C>T polymorphism and coronary artery disease in Chinese Han population were searched,all the literatures were evaluated and abstracted based on the defined selection criteria by two independent investigators.Public...
