【摘要】 目的 探讨脂蛋白脂酶(LPL)基因多态性与冠心病的关系。方法 选择106例住院存活的心肌梗塞病人按1∶1进行病例对照研究,采用条件Logistic回归分析。结果 吸烟、LPL基因型PVU Ⅱ(--)和单倍体基因型H+P-是冠心病独立的危险因素;高密度脂蛋白胆固醇(HDL-C)和载脂蛋白(Apo)A/B比值是冠心病的保护因素。去除其它因素的影响后,LPL PVUⅡ(--)/非(--)和H+P-/非H+P-的OR值为17.18和3.67;HDL-C、Apo A/B比值的OR值在模型A和B中分别为0.14、0.15和0.04、0.09。结论 除传统的危险因素外,LPL基因型PVUⅡ(--)和单倍体H+P-可能是易患冠心病的遗传标志;HDL-C、Apo A/B比值可能是较其它血脂指标更好的冠心病独立预测因素。 【关键词】 脂蛋白脂酶 基因,POL 冠状动脉疾病
Initial study on the association of lipoprotein lipase (LPL) gene polymorphisms with coronary heart disease (CHD) Qian Weichong, Wang Qiang, Zhu Tiebing, et al.

Methods 106 patients in myocardial infarction survivors were analyzed through a case-control study. Results The conditional logistic regression analysis demonstrated that 5 factors were associated with CHD. The risk factors were smoking, LPL genotype PVUⅡ(--) and haplotype H+P-, while high density lipoprotein cholesterol (HDL-C), apolipoprotein A/B (ApoA/B) ratio seemed as protective factors. After controlling the effect of the other variables, OR of LPL genotype PVUⅡ(--) and haplotype H+P- were 17.18 and 3.67, while OR of HDL-C, ApoA/B ratio were respectively 0.14, 0.15 in model A and 0.04, 0.09 in model B. Conclusion These results indicated that LPL genotype PVUII(--) or haplotype H+P- other than the conventional risk factors were contributing in CHD and that HDL-C, ApoA/B ratio may be the better independent predictors for CHD than the other plasma lipid parameters. 【Key words】 lipoprotein lipase gene, POL coronary heart disease
大量的临床及流行病学研究已经证明脂质代谢异常与冠心病的发生、发展密切相关,但不同类型的脂质异常对冠心病的不同影响仍有待进一步探讨[1,2]。脂蛋白脂酶(lipoprotein lipase,LPL)可以促进乳糜微粒和极低密度脂蛋白中甘油三酯(TG)的分解,LPL基因的异常可导致血TG水平的升高和高密度脂蛋白胆固醇(HDL-C)水平的降低,促进冠状动脉粥样硬化的形成和发[1] [2] 下一页 上一个医学论文: 临床实践与学习 下一个医学论文: 北京农民高血压患者干预前后静息心电图明尼苏达编码对比分析
