大量研究表明,天然高密度脂蛋白(native highdensity lipoprotein,N-HDL)与心血管事件危险性呈负相关,被认为是一种保护性脂蛋白。N-HDL通过参与胆固醇的逆向转运、拮抗低密度脂蛋白(low Den-sity Lipoprotein,LDL)氧化、保护内皮功能等机制发挥其抗动脉硬化(arteriosclerosis, Numerous studies have shown that natural high density lipoprotein (N-HDL) is inversely related to the risk of cardiovascular events and is considered as a protective lipoprotein. N-HDL exerts its anti-atherosclerosis (anti-atherosclerosis) mechanism by participating in the reverse transport of cholesterol, antagonizing the oxidation of low-density lipoprotein (LDL) and protecting the endothelial function,
