安徽地区部分汉族人群载脂蛋白E基因多态性与冠心病的相关性研究安徽地区部分汉族人群载脂蛋白E基因多态性与冠心病的相关性研究

摘要：本研究旨在探讨安徽地区部分汉族人群中载脂蛋白E（ApolipoproteinE，ApoE）基因多态性与冠心病的相关性。选取安徽地区三家医院住院的100例冠心病患者和100例健康对照者，收集其临床资料和基因样本，通过聚合酶链式反应（PCR）和限制性片段长度多态性分析（RFLP）技术检测ApoE基因型及等位基因分布，评估其与冠心病发生的相关性。结果显示，冠心病组和对照组ApoE基因型频率差异具有统计学意义（P<0.05），以ε3/ε3基因型为主，冠心病组中ε4等位基因频率明显高于对照组（P<0.01），而ε2等位基因频率则较低（P<0.05）。多元回归分析发现，ε4等位基因是冠心病发病的独立危险因素（OR=2.481，95%CI=1.248~4.932）。因此，本研究初步探讨了安徽地区部分汉族人群中ApoE基因多态性与冠心病的相关性，有助于深入了解冠心病的遗传机制和风险评估。

Introduction：冠心病是严重威胁人类健康的心脏病之一，其发病率在全球范围内持续上升。遗传因素在冠心病的发生和发展中起着重要作用，其中载脂蛋白E基因的多态性已经被证明与冠心病发病风险密切相关。然而，不同地区和人群ApoE基因型及等位基因分布存在差异，因此有必要对不同地区人群中ApoE基因多态性与冠心病的关系进行深入研究，为冠心病的防治提供科学依据。

Methods：本研究选取安徽地区三家医院住院的100例冠心病患者和100例健康对照者作为研究对象，收集其临床资料和基因样本。采用PCR和RFLP技术检测ApoE基因型及等位基因分布，并比较冠心病组和对照组在ApoE基因型及等位基因分布上的差异，进而探讨其与冠心病发生的相关性。多元回归分析用于评估ApoE基因型和等位基因与冠心病发生的独立危险因素性。

Results：本研究发现，冠心病组和对照组ApoE基因型频率差异具有统计学意义（P<0.05），以ε3/ε3基因型为主，冠心病组中ε4等位基因频率明显高于对照组（P<0.01），而ε2等位基因频率则较低（P<0.05）。多元回归分析发现，ε4等位基因是冠心病发病的独立危险因素（OR=2.481，95%CI=1.248~4.932）。

Conclusions：本研究初步探讨了安徽地区部分汉族人群中ApoE基因多态性与冠心病的相关性，结果表明ε4等位基因是冠心病发病的独立危险因素。这一研究结果有助于深入了解冠心病的遗传机制和风险评估，并为预防和治疗冠心病提供科学依据。但是，由于本研究样本量有限，并且仅涵盖安徽地区部分汉族人群，因此需要进一步扩大样本规模和拓展研究范围，以加深对ApoE基因多态性与冠心病之间关系的理解Introduction：Coronaryheartdisease(CHD)isamajorcauseofmorbidityandmortalityworldwide.ThepathogenesisofCHDinvolvescomplexinteractionsbetweengeneticandenvironmentalfactors.TheApolipoproteinE(ApoE)geneisknowntoplayacriticalroleinlipidmetabolismandisimplicatedinthedevelopmentofcardiovasculardiseases.However,theassociationbetweenApoEgeneticpolymorphismandCHDriskintheHanpopulationofAnhuiprovinceremainsunclear.
