目的:高脂血症是指血浆中各项脂质指标浓度水平超过机体正常范围,也称为血脂异常。高脂血症是动脉粥样硬化及冠心病等重大心脑血管疾病的潜在致病因素和独立危险因素。防治高脂血症对控制心脑血管疾病的发病率、致残率、死亡率和提高治愈率具有非常重要的现实意义。近几年的研究发现,一些基因的表达失衡,使血脂代谢的受体、载脂蛋白或酶发生异常改变,脂蛋白的合成、转运和代谢过程出现紊乱,从而导致血脂代谢过程异常,血脂水平升高。低密度脂蛋白受体(Low-density lipoprotein receptor,LDLR)是一种镶嵌在肝细胞膜有被小窝内,且在肝脏组织表达最为丰富的膜糖蛋白,在正常的机体脂质代谢过程中,其主要功能是结合并摄取血液循环中大部分富含胆固醇的低密度脂蛋白(Low density lipoprotein,LDL)进入细胞内,用以进行固醇类激素、细胞增殖和胆汁酸盐等的合成,这一过程被称为LDLR途径(LDLR pathway)。自2003年Seidah等发现前蛋白转化酶枯草杆菌蛋白酶9(proprotein convertase subtilisin/kexin type 9,PCSK9)以来,越来越多的证据显示,P...
【英文摘要】
Objective:Hyperlipidemia(HL)is concentration of lipids in plasma beyond the normal range.Modern medicine is also known as dyslipidemia,Hyperlipidemia is a potential pathogenic factor for major diseases such as atherosclerosis and coronary heart disease.Prevention of hyperlipidemia has very important practical significance in controlling the morbidity and mortality of cardiovascular and cerebrovascular diseases.In recent years,studies have found that the imbalance of expression of some genes can cause abnorm...
