Objective To investigate the association between ten single nucleotide polymorphism (SNP) in the peroxisome proliferator-aetivated receptor (PPAR) α/δ/γ and essential hypertension (EH).Methods Participants were recruited within the framework of a cohort populations survey from the PMMJS (Prevention of Multiple Metabolic Disorders and MS in Jiangsu Province) which was conducted in the urban community of Jiangsu province from 1999 to 2007.Eight handred and twenty subjects (551 non-hypertensive subjects,269 hypertensive subjects) were randomly selected but were not related to each other.Ten SN P ( rs 135539,rs1800206,rs4253778 of PPAR αt; rs2016520,rs9794 of PPARδ ; rs10865710,rs1805192,rs4684847,rs709158 and rs3856806 of PPARγ ) were selected from the HapMap database.x2 test was used to determine whether the whole population was in H-W genetic equilibrium.SHEsis software was used to examine the relations of SNP and linkage equilibrium.Logistic regression model was used to examine the association between ten SNP in the PPAR and EH.Results Difference on the distribution of four SNP genotypes including rs1800206,rs9794,rsl0865710 and rs4684847 between high blood pressure and non-high blood pressure group,high systolic blood pressure(SBP) and normal SBP group,high diastolic blood pressure(DBP) and normal DBP group was significant (P＜0.05).After adjusting factors as age,sex,body mass index,fasting plasma glucose,high density lipoprotein cholesterol-C,high-fat diet and compared with wildtype gene carriers,the OR(95％ CI) of objects with rs1800206 V allele appeared in high blood pressure,high SBP and high DBP were 0.60 (0A1-0.89),0.57 (0.37-0.88) and 0.61 (0.39-0.96),respectively.The OR(95％CI) of objects with G allele of rs9794 were 0.63 (0.46-0.87),0.51 (0.36-0.73) and 0.68(0.47-1.01).The OR (95％CI) of objects with G allele of rs10865710 were 1.62 (1.19-2.20),1.59(1.14-2.22) and 1.53 ( 1.07-2.18),respectively.While the OR (95％ CI) of objects with rs4684847 T allele were 1.42 ( 1.04-1.94),1.38 (1.03-1.92) and 1.37 ( 1.00-1.88),respectively.Conclusion The four SNPs including rs1800206 of PPARα,rs9794 of PPARδ and rs4684847,rs10865710 of PPARγ influenced high blood pressure,high SBP and high DBP to different degrees.%目的 探讨过氧化物酶体增殖物激活受体(PPAR)α/δ/γ10个单核苷酸多态性(SNP)位点与原发性高血压(EH)的关联.方法 采用单纯随机抽样方法抽取“江苏省多代谢异常和代谢综合征综合防治研究(PMMJS)”队列人群中的820名研究对象,对其基线血样本的DNA进行PPARα/δ/γ10个SNP位点(PPARα:rs135539、rs1800206、rs4253778; PPARδ:rs2016520、rs9794及PPARγ:rs10865710、rs1805192、rs4684847、rs709158、rs3856806)多态性检测.利用x2检验确定人群是否符合H-W遗传平衡定律,应用SHEsis软件对各位点进行连锁平衡检验,用logistic回归模型分析SNP与EH的关联.结果 rs 1800206、rs9794、rs10865710和rs4684847四个SNP位点在高血压和正常血压组间、高SBP和正常SBP组间及高DBP和正常DBP组间的分布差异有统计学意义(P＜0.05).调整性别、年龄、体重指数、空腹血糖、高密度脂蛋白胆固醇和高脂饮食后,与野生型基因携带人群相比,rs1800206位点V等位基因携带人群发生高血压、高SBP及高DBP的OR值( 95％CI)分别为0.60(0.41～0.89)、0.57(0.37～0.88)和0.61(0.39～0.96)；rs9794位点G等位基因携带人群发生高血压、高SBP及高DBP的OR值(95％CI)分别为0.63(0.46～0.87)、0.51(0.36～0.73)和0.68(0.47～1.01)；rs10865710位点G等位基因携带人群发生高血压、高SBP及高DBP的OR值(95％CI)分别为1.62(1.19～2.20)、1.59(1.14～2.22)和1.53(1.07～2.18);rs4684847位点T等位基因携带人群发生高血压、高SBP及高DBP的OR值(95％CI)分别为1.42(1.04～ 1.94)、1.38(1.03～1.92)和1.37(1.00～ 1.88).结论 PPARα的rs 1800206、PPARδ的rs9794及PPARγ的rs10865710和rs4684847四个SNP不同程度地影响高血压、高DBP及高SBP的发生.
