【摘要】 目的　ＡＴ１的Ａｌｌ６６Ｃ基因多态性与２型糖尿病、２型糖尿病合并冠心病的关联。方法用聚合酶链反应－限制性片段长度多态性分析法（ＰＣＲ－ＲＦＬＰ）探查ＡＴ１的Ａｌｌ６６Ｃ 基因多态在正常对照组（７３例）、单纯２型糖尿病组（简称糖尿病组８０例）、２型糖尿病合并冠心病组（简称合并冠心病组４３例）中的基因频率分布，并分析其对以上疾病发病因素的影响。结果 ２型糖尿病合并冠心病组 ＡＴ１的 １１６６Ｃ等位基因频率明显高于对照组（Ｘ２＝６． ０２，Ｐ＜０． ０５）和单纯糖尿病组（Ｘ２＝５．７１，Ｐ＜０．０５）。结论我们的结果提示携带ＡＴ１１１６６Ｃ等位基因的２型糖尿病患者比携带Ａ等位基因更易罹患冠心病。更多还原

【Abstract】 Objective To determine whether the AT, All66C gene polymorphism is associated with CHD in type 2 diabetes patients. Methods Investigating the allele frequency and the genotype distribution of the AT1 All66C gene in the group of normal control (n= 73),simple diabetes (n= 80),diabetic CHD (n=43) by means of PCR-RFLP. Results The group of diabetic CHD had a significant higher frequency of C allele of the AT1 All66C gene than normal control (X2 = 6. 02,P＜0. 05) and diabetes (X2= 5. 71,P＜0. 05). Conclusion The result indicated that there was an association between the 1166C allele of the AT1 gene polymorphism and CHD in type 2 diabetes patients.更多还原
