摘要: 目的 研究血管紧张素II2型受体基因1675A/G多态性与男性原发性高血压相关性。方法 随机选取山东省济宁地区男性原发性高血压患者113例和体检正常的男性101例作对照,提取外周血DNA进行AGTR2基因1675A/G多态性检测,收集临床资料,提取全血基因组DNA, 采用多聚酶链式反应 (PCR) 、高分辨率融解曲线(HRM)、基因测序方法测定AGTR2基因多态性。结果 AA、GG基因型在男性EH组的分布为56(49.6%)、57(50.4%),显著高于正常对照组的32(31.7%)、69(68.3%),(p<0.05)。等位基因频率在高血压组中分别为A:112(49.6%)和G:114(50.4%),显著高于正常对照组的A:64(31.7%)和G:138(68.3%),(P<0.05)。结论 AGTR2基因1675A/G多态性可能与山东省济宁地区男性原发性高血压有明显相关性。

Abstract: Objective:To investigate the relationship between the AT2-receptor 1675A/G gene polymorphism and essential hypertension in men. Methods: The studied objects were born in Jining city 113 EH male patients are EH group , with 101 healthy people as control group.To gather clinical data and extract DNA from blood with reagent-case.The 1675A/G polymorphism of AGTR2 gene was detected by PCR , HRM and gene sequencing. Result: There were difference in genetypes(AA、GG) distribution and allele frenqency of AGTR2 1675A/G between male EH and control group(p<0.05). Genotypes(AA、GG) distribution in EH group: 56(49.6%),57(50.4%),is significantly higher than in control group, 32 (31.7%), 69 (68.3%), (p < 0.05). Allele frenqency in EH group: A:112(49.6%)and G:114(50.4%), is significantly higher than in control group: 32(31.7%)and 69(68.3%)(p<0.05). Conclusion:The 1675A/G polymorphism of AGTR2 gene may be associated with male EH in Jining area ,Shandong province.
