摘要: 为探讨血管紧张素Ⅰ转换酶(ACE)基因插入/缺失(I/D)多态性与非胰岛素依赖型糖尿病(NIDDM)及其视网膜病变的关系,以ACE基因第16内含子1个287bpAlu顺序I/D型为多态性标志,用聚合酶链反应(PCR)扩增基因片段,1%琼脂糖凝胶电泳PCR产物.结果87例NIDDM与50例正常人之间基因频率无显着差异;NIDDM合并视网膜病变与未合并视网膜病变2组间基因型频率和等位基因频率无显着差异.提示糖尿病视网膜病变与ACE基因多态性无关.

Abstract: o clarify whether angiotensin converting enzyme(ACE)insertion(I)/deletion(D)gene polymorphism attributes to the development of non-insulin dependent diabetes mellitus(NIDDM)and diabetic retinopathy. A fragment of 287 bp Alu sequence in inron 16 of ACE gene was used as I/D polymorphic marker. After PCR(polymerase chain reaction)amplication of DNA fragment, 1% agarose gel electrophoresis was undertaken to analyse the PCR products. Results: There was no significant difference in the frequency of ACE genotypes between 87 NIDDM patients and 50 normal subjects. There was no significant difference in the insertion(I)and deletion(D)alleles or frequencies of DD, DI, or II genotypes between two subgroups of NIDDM patients with and without diabetic retinopathy respectively(P<0.02). These results suggested that there was no association between ACE gene polymorphism and diabetic retinopathy.

Key words: diabetic retinopathy, noninsulin diabetes mellitus, ACE gene
