摘要
目的 探究载脂蛋白（Apo）A1-75 bp（G/A）位点多态性与血脂谱及冠状动脉病变程度的相关性.方法 入选2011年10月到2013年10月就诊于广东省人民医院的胸痛患者723例,根据冠状动脉造影结果分为冠心病组444例和正常对照组279例,其中男472例,女251例,平均年龄（62.4±10.2）岁.比较两组间一般资料、血脂及-75 bp位点多态性,分析-75 bp位点多态性对血脂谱的影响.采用logistic多因素回归分析冠心病的危险因素,并根据Gensini评分进行分组,Gensini评分=0（n=98）,0＜ Gensini评分≤30（n=223）,30＜ Gensini评分≤60（n=184）,Gensini评分＞60（n =218）,比较各组-75 bp位点多态性的差异.结果 冠心病组中男性、吸烟和糖尿病比例、总胆固醇（rC）、甘油三酯（TG）、低密度脂蛋白胆固醇（LDL-C）水平均高于正常对照组,而高密度脂蛋白胆固醇（HDL-C）、ApoA1水平低于正常对照组（P＜0.05）;冠心病组的ApoA1-75 bp位点A等位基因频率为43.7％（194/444）,低于正常对照组的56.6％ （158/279） （P =0.003）.在血脂谱分析中,-75 bp位点突变型（GA/AA）的HDL-C、ApoA1水平高于野生型（GG）,差异有统计学意义（男：P=0.033,0.011;女：P=0.007,0.036）.logistic多因素回归分析提示-75 bp位点变异是冠心病的保护因素（OR=0.649,P=0.021）.随着Gensini评分的增加,A等位基因频率减少（男：P=0.012;女：P=0.006）.同时,-75 bp位点突变型与冠状动脉病变严重程度相关,以Gensini评分=0为对照,0＜Gensini评分≤30、30＜Gensini评分≤60及Gensini评分＞60的OR值分别为0.541、0.446、0.331（P均＜0.05）.结论 ApoA1-75 bp位点多态性与冠心病患者血脂谱和冠状动脉病变程度相关,ApoA1-75 bp位点突变型是冠心病的保护因素.
Objective To explore the relationship between the apolipoprotein ApoA1-75 bp polymorphism and risk for dyslipidemia and coronary artery disease （CAD）.Methods A total of 723 patients （mean age （62.4 ± 10.2） years old） admitted to Guangdong General Hospital from 2011 to 2013 were enrolled.They were subdivided into CAD group （n =444） and non-CAD （n =279） group according to the result of coronary angiography （CAG）.Clinical data including the profiles of lipids,-75 bp gene polymorphisms and Gensini scores were analyzed to determine the correlation between-75 bp gene polymorphisms,lipid profile and CAD.Result Frequency of male gender,history of diabetes and smoking,TC,TG,LDL-C and ApoB level were significantly higher and HDL-C level was significantly lower in CAD group than in non-CAD group （all P ＜ 0.05）.Frequency of A allele was significantly lower in CAD group than in non-CAD group （43.7％ （194/444） vs.56.6％ （158/279）,P =0.003）.The ApoA1-75 bp gene polymorphism was significantly correlated with CAD （P ＜ 0.005）.Multivariate logistic regression analysis showed that-75 bp gene polymorphism mutation （OR =0.649,P =0.021） is an independent protective factor for coronary heart disease.Conclusion ApoA1-75 bp gene polymorphism is linked with risk of dyslipidemia and CAD.
