摘要
目的 探讨血管紧张素原(angiotensinogen , A G T) 基因 M235 T 分子变异与中国人无肾病并发症的2 型糖尿病(diabetes m ellitus , D M) 、2 型糖尿病肾病(diabetic nephropathy , D N) 的关系。方法 用 P C R及 R F L P 方法对84 例 D M、96 例 D N 及98 名正常对照进行了 A G T 基因 M235 T 多态性的检测。结果 D N 组 T 等位基因频率082 , T T 基因型频率070 ,与对照组(063 ,043) 比较有显著差异( P= 0003 , P=00004) ;校正了 D N 的几种危险因素后, T T 基因型对 D N 的 O R 为347(95 % C I 为151 ~794 , P=00033) 。 D M 组基因型频率分布与对照组比较无显著差异( P> 005) 。结论 A G T 基因 T T 型可能是中国人群2 型糖尿病肾病的独立危险因素之一。
Objective To investigate whether angiotensinogen (AGT) gene M235T variant is associated with type 2 diabetes mellitus without nephropathy(DM) and/or diabetic nephropathy(DN) in Chinese type 2 diabetes.Methods AGT genotypes of 84 cases with DM, 96 with DN and 98 controls were determined by polymerase chain reaction(PCR) amplification and restriction fragment length polymorphism analysis of the region of the variant.Results Increased frequencies of T allele(0.82) and TT genotype (0.70) were observed in 96 subjects with DN, compared with those observed in 98 control subjects (0.63 and 0.43 respectively, P =0.003, P =0.0004).The odds ratio associated with TT genotype was 3.47(95% CI 1.51 7.94, P =0.0033) for DN in analysis adjusted for several DN risk factors. There was no difference in allele distribution between 84 DM patients and the contorls.Conclusion TT genotype of the AGT gene might be an independent risk factor of diabetic nephropathy in Chinese patients with type 2 diabetes mellitus.
