摘 要:目的探讨解耦联蛋白2(UCP-2)基因启动子.866G/A多态性与中国人糖尿病肾病(DN)的关系。方法182例2型糖尿病患者,其中并发DN90例(DN组),无肾病92例(NCD组),检测所有患者的基因组DNA,采用聚合酶链反应.限制性长度多态性方法,记录UCP-2等位基因及基因型频率并进行比较。结果UCP-2基因启动子.866G/A多态性在DN组中基因型频率分布,GG14.44%(13,90),GA31.11%(28/90),AA54.44%(49/90),在NCD组中基因型频率分布,GG29.35%(27/92),GA32.61%(30/92),AA38.04%(35/92),两组比较差异有统计学意义(r=7.28,P〈0.05);NCD组UCP-2等位基因频率分布,G45.65%(84/184),A54.35%(100/184),DN组UCP-2等位基因频率分布,G30.00%(54/180),A70.00%(126/180),两组比较差异有统计学意义(r=9.47,P〈0.05)。结论UCP-2基因启动子.866G/A多态性与中国人DN相关,A,A基因型携带者DN发病率高。Objective To investigate the relationship between uncoupling protein 2 (UCP-2) gene promoter -866 G/A polymorphism and Chinese diabetic nephropathy (DN). Methods A total of 182 patients with type 2 diabetic mellitus were selected and divided into DN group (90 cases with DN ) and NCD group (92 cases without DN). Genomic DNA was detected, and UCP-2 genotype and allele gene frequency was confirmed by polymerase chain reaction-restrictive fragment length polymorphism, then compared. Results The genotype frequency of UCP-2 gene promoter-866 G/A polymorphism was distributed in DN group [GG 14.44%( 13/90),GA 31.11%(28/90),AA 54.44%(49/90) ],and distributed in NCD group [GG 29.35% (27/92) ,GA 32.61% (30/92) ,AA 38.04% (35/92) ] ,and there was significant difference between two groups (X2 = 7.28 ,P〈 0.05). There was also significant difference in allele gene frequency between DN group and NCD group [G 45.65% (84/184) vs. 30.00% (54/180),A 54.35% (100/184) vs. 70.00% (126/180) ] ( X2 = 9.47 ,P 〈 0.05 ). Conclusion There is correlation between the UCP-2 gene promoter-866 G/A polymorphism and Chinese DN, and the incidence of DN with A/A genotype is increased.
