摘要
目的 通过meta分析评估神经分化因子1(Neuro1D1)Ala45Thr基因多态性与2型糖尿病的关联性.方法 通过系统检索PubMed、EMBASE、CNKI、万方数据库、维普数据库等中英文数据库,在Kavvoura等已发表1999年至2004年NeuroD1 (Ala45Thr)基因多态性与2型糖尿病关联性的meta分析基础上,纳入2004年至2012年有关NeuroD1 (Ala45Thr)基因多态性与2型糖尿病相关性的研究,以2型糖尿病组和正常对照组基因分布的OR值为统计量,应用Rev Man 5.0软件对研究结果进行异质性检验和相关数据的合并,最终纳入13篇病例对照试验文献.结果 共入选2型糖尿病患者3 896例,对照组3 186名.Meta分析结果显示,黄种人2型糖尿病与对照组Thr45Thr45/(Ala45Thr+Ala45Ala45) OR值为3.16(95%CI0.99 ~10.11),白种人OR值为1.09(95% CI0.90~ 1.32),差异均无统计学意义(P>0.05) 而2型糖尿病组和对照组G/A等位基因频率OR值为0.85(95% CI0.72 ~0.99)/1.18(95% CI.07 ~ 1.38),差异有统计学意义(Z=2.02,P=0.04).结论 NeuroD1 (Ala45Thr)位点A等位基因可能是2型糖尿病的危险因素.
Objective To investigate the association of neural differentiation factor 1 (NeuroD1) Ala45Thr polymorphism with type 2 diabetes by meta-analysis.Methods The electronic databases were retrieved from PubMed,EMBASE,CNKI,VIP fulltext database,and Wanfang fulltext database.Literatures about the association of NeuroD1 Ala45Thr polymorphism with type 2 diabetes from 2004 to 2012 were searched.The selected studies from 2004 to 2012 were included to analyze data based on the published meta-analysis of the NeuroD1 (Ala45Thr) gene polymorphism and type 2 diabetes written by Kavvoura,et al.The odds ratio of NeuroD1 (Ala45Thr) genotype distributions in type 2 diabetic patients compared with healthy control were analyzed.Rev-Man 5.0 software was applied for investigating hereogeneity among individual studies and summarizing effects with proper statistical methods.Thirteen case control studies were enrolled.Results A total of 3 896 patients and 3 186 control subjects were enrolled for the study.The pooled ORs of Thr45Thr45/(Ala45Thr+ Ala45Ala45) genotype in type 2 diabetes mellitus and control groups were 3.16 (95% CI0.99-10.11) in the subgroup of yellow race and 1.09(95% CI0.90-1.32) in the subgroup of white race,with no statistically significant difference(P〉0.05).The pooled OR of G/A allele in type 2 diabetes mellitus and control groups was 0.85 (95 % CI 0.72-0.99)/1.18 (95% CI 1.07-1.38),with statistically significant difference (Z =2.02,P =0.04).Conclusions The A allele of NeuroD1 (Ala45Thr) locus may be a risk factor for type 2 diabetes mellitus.
