代谢综合征与冠心病的载脂蛋白E基因多态性

目的:探讨代谢综合征(metabolicsyndrome,MS)与冠心病(coronaryarterydisease,CHD)的载脂蛋白E(apolipoproteinE,ApoE)基因多态性之间的关联。方法:将203例原发性高血压、糖尿病或原发性高血压合并糖尿病的患者分为代谢综合征组(按WHO定义,MS+,n=96)和非代谢综合征组(MS-,n=107);冠心病组(CHD+,n=84)和非冠心病组(CHD-,n=119);代谢综合征合并冠心病(MS++CHD,n=55)及代谢综合征非合并冠心病组(MS+,n=39)。采用聚合酶链反应-限制性片段长度多态性(PCR-RFLP)确定特定ApoE片段基因型,应用荧光标记自动测序法测定PCR产物,确认单核苷酸多态性(singlenucleotidepolymorphisms,SNPs)位点。结果:(1)MS组ApoEε4等位基因频率高于对照组(15.6%vs8.9%,P=0.038);(2)CHD组ε4等位基因频率显著高于对照组(16.8%vs8.8%,P=0.017);(3)MS+CHD组ε4等位基因频率显著高于对照组(21.8%vs7.3%,P=0.006);与...

The relationship of apolipoprotein E gene polymorphism to metabolic syndrome and coronary artery disease

Objective To evaluate the relationship of apolipoprotein E(ApoE)gene polymorphism to metabolic syndrome(MS) and coronary artery disease(CHD). Methods Two hundreds and three patients with essential hypertension, diabetes mellitus or essential hypertension complicated with diabetes mellitus were divided into two groups: metabolic syndrome (WHO definition, MS+, n=96) and Non metabolic syndrome (MS-, n=107);coronary artery disease(CHD+, n=84 )and non coronary artery disease(CHD-, n=119); metabolic syndrome co...
