目的评估单核细胞趋化蛋白-1(MCP-1)-2518G/A基因多态性与糖尿病肾病(DN)发病风险的关系。方法系统检索PubMed、Web of Science、EMbase、Cochrane Library、中国知网(CNKI)、万方和维普数据库中截至2016年10月收录的所有有关MCP-1-2518...目的评估单核细胞趋化蛋白-1(MCP-1)-2518G/A基因多态性与糖尿病肾病(DN)发病风险的关系。方法系统检索PubMed、Web of Science、EMbase、Cochrane Library、中国知网(CNKI)、万方和维普数据库中截至2016年10月收录的所有有关MCP-1-2518G/A基因多态性与DN发病风险的文献。提取相关数据,应用STATA11.0统计软件计算合成数据的比值比(OR)和95%可信区间(CI),同时评估研究的异质性、发表偏倚。结果共纳入的9项研究涉及2 767例独立样本,其中病例组为1 096例,对照组为1 671例。对于总体人群,在4个基因模型中均未发现MCP-1-2518G/A多态性与DN发病风险有关(显性模型:OR=1.01,95%CI:0.67~1.54;隐性模型:OR=0.93,95%CI:0.60~1.44;纯合子模型:OR=0.93,95%CI:0.70~1.23;杂合子模型:OR=0.89,95%CI:0.61~1.31)。亚组分析结果显示,在印度人群中,MCP-1-2518G/A基因多态性会显著增加DN的发病风险(显性模型:OR=1.56,95%CI:1.19~2.06),但在中国人、土耳其人及韩国人中均未发现MCP-1-2518G/A基因多态性与DN的发病风险有关。结论总体人群中,MCP-1-2518G/A位点基因多态性与DN发病风险无关,但MCP-1-2518G/A位点多态性会增加印度人群DN发病风险,而不增加中国人群、韩国人群、土耳其人群中DN的发病风险。展开更多
