摘要
目的研究过氧化物酶体增殖物激活受体(PPAR)基因单核苷酸多态性(SNP)与动脉僵硬度的关系。方法以流行病学调查方法了解心血管危险因素情况,用Complior系统测量颈股段脉搏波传导速度(efPWV)。用efPWV评价动脉僵硬度,将cfPWV〉12m/s作为动脉僵硬度增高标准,将研究对象分为动脉僵硬度正常组(844例)与增高组(530例)。用实时定量聚合酶链反应、TaqMan探针法获得1374例PPARet、PPARB、PPARγC1a基因的rs1053049、rs1800234和rs8192678等3个SNP位点基因型,分析传统心血管危险因素、基因型与动脉僵硬度的关系。结果动脉僵硬度增高组的平均年龄[(67.9±8.8)岁比(58.0±9.7)岁]、高血压[71.1%(377/530)比30.5%(257/844)]和糖尿病发生率[21.7%(115/530)比11.0%(93/844)]均高于动脉僵硬度正常组(P均〈0.01)。动脉僵硬度正常与增高组,rs8192678的CC基因型分别为272例(32.2%)和163例(30.8%),CT基因型分别为411例(48.7%)和276例(52.1%),TT基因型分别为161例(19.1%)和91例(17.2%);rs1053049的CC基因型分别为470例(55.7%)和272例(51.3%),CT基因型分别为310例(36.7%)和207例(39.1%),TT基因型分别为64例(7.6%)和51例(9.6%);rs1800234其CC基因型分别为746例(88.4%)和479例(90.4%),CT+TT基因型分别为98例(11.6%)和51例(9.6%)。两组间3个SNP位点分布差异均无统计学意义。结论年龄、高血压、糖尿病等心血管危险因素与动脉僵硬度相关,未发现PPAR、PPARγC1a基因的SNP位点与动脉僵硬度相关。
Objective To analyze the association between single nucleotide polymorphisms (SNPs) of peroxisomc proliferator-activated receptor(PPAR) and arterial stiffness in adult Chinese population ( 〉 50 years). Methods Cardiovascular risk factors from participants of Beijing epidemiological investigation were analyzed. Carotid-femoral pulse wave velocity (cfPWV) was measured by Complior system. The subjects were divided into normal arterial stiffness group (cfPWV 〈 12 m/s, n = 844 ) and increased arterial stiffness group (cfPWV 〉 12 m/s, n = 530). Three valid SNPs including rs1053049, rs1800234 and rs8192678 in the PPAR and PPARγCla gene were genotyped by TaqMan allelic discrimination assays. Results The age [(67.±8.8) years vs. (58.0±9.7) years], prevalence of hypertension[71.1% (377/530) vs. 30.5% (257/844)] and diabetes mellitus [21.7% (115/530) vs. 11.0% (93/844)] were all significantly higher in increased arterial stiffness group than in normal group (all P 〈 0. 05 ) . The frequencies of CC, CT and TT type of rs8192678 [ CC:32. 2% (272/844) vs. 30. 8% ( 163/530), CT: 48. 7% (411/844) vs. 52. 1% (276/530), TT: 19. 1% (161/844) vs. 17.2% (91/530) ], rs1053049 [CC: 55.7% (470/844) vs. 51.3% (272/530), CT: 36. 7% (310/844) vs. 39.1% (207/530), TY: 7.6% (64/844) vs. 9.6% (51/530) ] and rs1800234 [ CC : 88.4% (746/844) vs. 90.4% (479/530), CT +TT : 11.6% (98/844) vs. 9.6% ( 51/530) ] were similar between the two groups. There was also no association between haplotypes and the increased arterial stiffness in this cohort. Conclusions In this community-based population, we found that aging, hypertension and diabetes mellitus were associated but SNPs of PPAR and PPARγCla were not associated with arterial stiffness.
