汉族人群C反应蛋白基因多态性与冠心病和C反应蛋白水平相关性研究

目的研究汉族人群中C反应蛋白(CRP)基因启动子区-717A/G和-390C/A/T单核苷酸多态性(SNP)的分布以及与冠心病(CHD)和CRP水平的相关性。方法选取2007年10月至2008年5月北京医院住院患者分为CHD组(111例)及对照组(101例)。-717A/G位点运用限制性酶切长度多态性(RELP)的方法检测基因多态性,-390C/A/T位点运用序列特异性的聚合酶链反应(SSP)检测多态性。为排除其他危险因素的干扰,综合考虑与CHD相关的其他危险因素,运用Logistic回归的方法分析相关性。结果在汉族人群中-717A/G多态性各种等位基因与基因型研究对象的CRP水平差异无统计学意义,各等位基因频率和基因型频率在CHD和对照组中分布差异无统计学意义。-390C/A/T多态性与CRP水平相关,-390C/A/T多态性的等位基因频率(P<0.05)基因型频率(P<0.05)在两组之间差异有统计学意义。分析CHD相关危险因素发现该位点依然与CHD显著相关,带有T等位基因的个体得CHD的概率是不带T等位基因个体的2.66倍。结论-717A/G多态性与CRP水平和CHD未见相关;CRP基因-390C/A/...

Association of coronary heart disease with two polymorphisms within C reactive protein gene promoter region in ethnic Han Chinese

Objective To investigate the distribution of two single nucleotide polymorphism(SNP)-717A/G and-390C/A/T-within the C reactive protein(CRP)promoter region in ethnic Han Chinese and the association with coronary heart disease(CHD).Methods Altogether positive CHD patients and negative controls were studies in this study.The two target fragments were amplied by PCR.Then the-717A/G polymorphism was screened by restriction fragment length polymorphism(RFLP)and the-390C/A/T polymorphism by Sequence Specific PCR(S...
