Abstract:
Objective To study the correlation between the genetic polymorphism of tumor necrosis factor-α(TNF-α)-308 with benazepril treatment response in the patients with hypertensive renal damage in Ningxia area.Methods Two hundred and eighty-four patients initially diagnosed as hypertension were enrolled and the hypertensive renal damage defined by the measurement of urinary albumin excretion rate(UAER).At the same time 160 individuals undergoing healthy physical examination were selected as the normal blood pressure control group.The plasma samples were obtained from all the subjects,and plasma level of TNF-α and TNF-α-308 gene polymorphism were detected.Then the patients with hypertensive renal damage were interfered with benazepril as one of the antihypertensive drugs,and the treatment response of different TNF-α-308 genotypes to benazepril was observed,and the comparative analysis was performed.Results Among the TNF-α-308 genotypes in the patients with simple hypertension,genotype GA was the most common,followed by GG and AA successively,with the G/A allele frequency of 53 ％/47 ％ (P＜0.05).In the patients with hypertensive renal damage,genotype GG was the most common,followed by GA and AA successively,with the G/A allele frequency of 70％/30％,the genotypes and allele frequency had no statistical difference(P＜0.05).Before and after benazepril treatment,the change range of UAER in the patients with genotype AA was maximal,followed by the genotype GA and GG,the difference among 3 groups was statistically significant(P＜0.05).Conclusion The TNF-α-308 gene is correlated with hypertensive renal damage and its response to benazepril treatment.
