摘要 高密度脂蛋白(HDL)是由脂质和脂蛋白组成的复合体,功能复杂、容易变异。正常的HDL具有保护心血管的作用,但应用胆固醇酯转移蛋白抑制剂和烟酸升高血浆HDL胆固醇(HDL-C)水平并不能降低心血管事件发生率。提示可能是HDL功能而不是HDL-C水平起关键作用。研究发现冠心病、糖尿病、慢性肾病、风湿性关节炎和心脏外科手术等疾病状态会使HDL功能发生改变,不但不具有保护心血管的作用,而且对心血管有损害,称为趋炎HDL或功能异常HDL。趋炎HDL与正常HDL成分不同,它逆向转运胆固醇的能力下降,抗炎抗氧化能力受损,可损伤血管内皮功能。运动、载脂蛋白A-I模拟肽、辛伐他汀等可部分改善HDL功能。因此,有关HDL的研究更应关注HDL功能和其成份在疾病中的改变、如何改变机体内环境,防止新生HDL转变为趋炎HDL,以及如何改善这些HDL的功能,使其恢复保护心血管的特性。
