1、甲巯咪唑致肝损害与黄素单加氧酶3E308G位点基因多态性的相关性研究殷静,王芳,王永艳,汤洪策,孙纯,阎胜利(青岛大学附属医院内分泌科,山东青岛266003)摘要:目的探讨黄素单加氧酶3(flavin—containingmonooxygenase,FMO3)E308G位点基因多态性与甲巯咪唑(methimazole,MMI)致山东地区汉族Graves病(GD)患者肝损害的相关性。方法研究对象选自2011年3月至2012年4月到本院内分泌科就诊、住院的Graves病患者(GD组)105例,分为2个亚组:甲巯咪唑治疗后肝损害组(肝损害组)和甲巯咪唑治疗前后肝功正常组
2、(肝功正常组)。记录患者临床资料,收集其外周非抗凝静脉血血凝块,提取基因组DNA,应用聚合酶链反应.限制性片段长度多态性技术(PCR—RFLP)测定黄素单加氧酶3基因E308G位点基因型,计算两组的基因型和等位基因频率。结果黄素单加氧酶3基因E308G位点的AG-4-GG基因型和G等位基因频率在肝损害组与肝功正常组分布差异有统计学意义(=7.744,P=0.0052=4.850,P=0.028)。Logistic回归分析结果显示,黄素单加氧酶3基因E308G位点G等位基因与甲巯咪唑致肝损害的发生相关,OR值为3.371,95%CI为1.357~8.379,P<0.
3、05。结论黄素单加氧酶3基因E308G位点多态性可能与山东地区汉族人群GD患者甲巯咪唑致肝损害相关。关键词:甲巯咪唑;黄素单加氧酶3基因;Graves病;肝损害doi:10.11669/cpj.2014.15.015中图分类号:R968文献标志码:A文章编号:1001—2494(2014)15—1338—04RelationshipbetweentheFlavin·ContainingMonooxygenase3GenePolymorphismsandtheLiverInjuryCausedbyMethimazoleYINJing,WANGFang,WANGYon
