摘要目的 系统评价CTLA-4+49基因多态性在中国、日本、韩国及泰国等不同人群中与Graves 病(Graves' disease,GD)遗传易感性的定量关系.方法 计算机检索PubMed、EMBASE、CNKI、万方等数据库,收集国内外关于中国、日本、韩国及泰国人群CTLA-4+49基因多态性与GD相关性的病例对照研究.采用meta分析的方法,对收集的文章进行定量综合分析.结果 本次分析共纳入24篇文献,GD病例组和健康人群对照组分别为4 832例和5 643名.meta分析结果发现,在总人群、中国人群、日本人群的所有基因模型中(等位基因、共显性模型、显性模型、隐性模型)均发现差异有统计学意义,表明CTLA-4+49A等位基因可降低GD的发生风险.结论 在亚洲人群中CTLA-4+49G→A等位基因的突变可能为降低GD的发病风险的一个因素.

abstractsObjective To review the quantitative relationship of polymorphism at the sites +49 of cytotoxic T-lymphocyte associated antigen 4 gene with the susceptibility of Graves' disease(GD) in Asian population.Methods The Medline,PubMed,Embase,Web of Science,and Chinese Biomedical Literature Database on disc (CBM disc) databases were searched and used in meta-analysis to analyze the data in the articles collected.Results This analysis included a total of 24 papers,and GD patients and healthy population control group were composed of 4 832 cases and 5 643 subjects respectively.This paper revealed that in the general population,the Chinese people and the Japanese crowd,all the genetic models (allele,co-dominant model,dominant model,recessive model) were statistically significant,indicating that CTLA-4 +49 A allele could reduce the risk of GD.Conclusions The CTLA-4 +49 G→A mutation allele may serve as a factor in reducing the risk of GD susceptibility in Asian population.
