摘要 目的:探讨血小板糖蛋白Ia/IIa分子Ia链(GPIa)BglⅡ限制性片段长度多态性与2型糖尿病视网膜病(DR)分型的关系。方法:运用聚合酶链反应—限制性片段长度多态性技术(PCR-RFLP)检测180例2型糖尿病(DM)患者(DR+组62例,DR-组118例)及85例正常对照组的(CON)基因型。其中单纯型DR44例,增殖型DR18例。结果:(1)DR+组BglⅡ(+/+)基因型频率及BglⅡ(+)等位基因频率-明显高于DR-组及CON组(P<0.01),BglⅡ(+)等位基因与DR明显相关(OR=2.01,95%CI,1.29~3.12);(2)单纯型DR组与增殖型DR组BglⅡ基因型及等位基因频率分布差异无显著性(P>0.05)。结论:BglⅡ(+)等位基因可能是2型DM合并视网膜病变的危险因子,但与DR的分型无明显关联。
