【摘要】 目的综合评价中国汉族人群HLA-DQ基因多态性与系统性红斑狼疮(SLE)的关联性。方法以系统性红斑狼疮病例组和健康对照组的各HLA-DQ等位基因频数分布的OR值为统计量,全面检索相关文献,应用M eta分析软件包Revm an 4.2,在基因分型水平上,对各研究的结果进行一致性检验和数据合并,并评估发表偏倚。结果等位基因DQA1*0102、DQB1*0601是中国汉族人群SLE患者的危险基因(均P<0.05),它们的合并OR值分别为:1.82,1.95;等位基因DQA1*0301、DQA1*0302、DQA1*0601、DQB1*0301、DQB1*0302、DQB1*0401和DQB1*0503是中国汉族人群SLE患者的保护基因(均P<0.05),它们合并OR值分别为:,0.72,0.43,0.36,0.40,0.39,0.24,0.41。结论中国汉族人群SLE与HLA-DQ的某些等位基因具有关联性,且存在区别于其他人群的特殊性。更多还原

【Abstract】 Aim To evaluate the relationship between genetic polymorphisms of HLA-DQ and systemic lupus erythematosus in Chinese population.Methods Odds ratios(OR) of HLA-DQ allele distributions in patients with SLE against healthy controls were analysed.All the relevant studies were identified,poor qualified studies excluded and the publication bias was evaluated.The Meta-analysis software,Revman 4.2,was applied for investigating heterogeneity among individual studies and for summarizing all the studies.Results DQA1*0102 and DQB1*0601 were the risky alleles(all P<0.05) in Chinese population,whose pooled OR values were 1.82,1.95.DQA1*0301,DQA1*0302,DQA1*0601,DQB1*0301,DQB1*0302,DQB1*0401 and DQB1*0503 were the protective alleles(all P<0.05),whose pooled OR values were 0.72,0.43,0.36,0.40,0.39,0.24,0.41 respectively.Conclusions In Chinese population,some HLA-DQ alleles are associated with the SLE,and these associations are different from those in other populations.更多还原
