1、血脂相关指标及动脉粥样硬化发展阶段相关性探究【摘要】目的通过检测动脉粥样硬化(As)不同发展阶段的各种血脂相关指标,来探讨各种检测值与As各个发展阶段的相关性。方法随机选择健康体检者60例(As(-)组)、脑As无并发症患者24例(As(+)组)、As性脑栓塞患者67例(As(++)组),酶化学法测定血清三酰甘油(TG)、总胆固醇(TC),直接法测定低密度脂蛋白胆固醇(LDLC)、高密度脂蛋白胆固醇(HDLC),免疫透射比浊法测定载脂蛋白AI(ApoAI)、载脂蛋白B100(ApoB100)、脂蛋白(a)(LP(
2、a)),并对3组的检测值进行统计分析。结果As(+)组与As(-)组比较,TG、TC、LDLC、ApoB100、LP(a)、ApoB100/ApoAI增高(PA和+83bpC―>T,在ApoAI基因中作上述碱基替代,可抑制ApoAI基因的转录和表达。这可解释,包含-75bpA和+83bpT的个体为什么具有较低的HDLC水平。�5本调查结果提示,TG、TC、LDLC、HDLC、ApoAI、ApoB100、LP(a)、ApoB100/ApoAI水平与As的早期发展阶段相关,而且ApoB100、LP(a)、ApoB10
3、0/ApoAI水平与As的晚期发展阶段相关。因此,较之于其它血脂相关指标,ApoB100、LP(a)和ApoB100/ApoAI更可靠,可作为诊断As发生发展的辅助指标,也可作为检测各种措施对As治疗效果的参考指标。�参考文献�1TiyyaguraSR,SmithDA.Standardlipidprofile.ClinLabMed,2006,26(4):707-732.�2ZabalawiM,BharadwajM,HortonH,etal.InflammationandskincholesterolinLDLr-
