摘要
目的探讨河南新乡地区汉族群体基质金属蛋白酶基因启动子区rs2285053、rs11225395、rs225207、rs243865及rs11568818这5个单核苷酸多态性(SNPs)与心力衰竭(CHF)发病的相关性。方法知情同意情况下,采集160例CHF患者(观察组)和186例健康体检者(对照组)外周静脉血提取基因组DNA,限制性扩增片段长度多态性方法对5个SNPs进行分型,运用SHEsis软件分析数据。结果与对照组相比,MMPs基因rs2285053位点T等位基因的频率在观察组中显著降低(P<0.05);rs11225395位点的T等位基因和TT基因型频率在观察组中也显著降低(P<0.05),OR=1.966[95%CI(1.236~3.129)];而观察组中rs225207的G等位基因频率显著增加(P<0.05),OR=0.499[95%CI(0.320~3.799];rs2285053、rs11225395、rs225207组成的单体型CCG在观察组中的频率增高(P<0.05)。结论 rs11225395和rs2285053位点的等位基因T有可能降低CHF的患病风险;而rs225207位点的等位基因G及单体型CCG可能会增加CHF的患病风险。
Objective To assess the relationship between 5 SNPs including rs2285053,rs11225395,rs225207,rs243865 and rs11568818 at the promoter region of matrix metalloproteinases(MMPs) genes and the risk of chronic heart failure(CHF) in Han population from Xinxiang city of Henan province. Methods 5 SNPs sites of 160 CHF patients(observation group) and 186 healthyin dividuals(control group) were genotyped by PCR-RFLP methods. Then the data was analyzed by SHEsis software. Results The frequency of T allele of rs11225395 of patients in the observation group was significantly lower than that in the control group(P < 0. 05). The frequency of T allele and TT genotype of rs11225395 of patients in the observation group was lower than that in the control group(P < 0. 05) OR = 1. 96[95%CI(1. 236 ~ 3. 129)〗. The G allele of rs225207 of patients in the observation group was higher than that in the control group(P < 0. 05),OR = 0. 499[95%CI(0. 320 ~ 3. 799〗. The haplotype CCG consisting of rs2285053,rs11225395 and rs2285053 of patients in observation group was higher than those in the control group(P < 0. 05). Conclusion T allele of rs2285053 and rs11225395,G allele of rs225207 and the haplotype CCG may decrease the risk of CHF.
