冠心病和肿瘤是危害40岁以上人群的主要疾病。对这两种疾病的主要对策是早期发现,早期治疗。早已证实冠心病是由于血浆中的胆固醇在冠状动脉管壁的沉积,形成粥样斑块堵塞血流,发生心绞痛、心肌梗死。故临床上在40年以前就开始测定血浆总胆固醇的含量,以判断诱发冠心病的可能性。但自1977年以后理论研究上的一个突破性贡献证明,血浆中存在两种胆固醇。一种是低密度脂蛋白胆固醇(LDL-C),这种胆固醇是血液运至各个细胞应用的,过量的LDL-C就会沉积于细胞内,是造成动脉粥样硬化的原因,因此有人称其为“致病性LDL-C”。另一种是高密度脂蛋白胆固醇(HDL-C),这种胆固醇是将周围组织细胞内过剩的胆固醇经血循环运至肝脏,随胆汁排出体
Coronary heart disease and cancer are the major diseases that endanger people over 40 years of age. The main countermeasure for these two diseases is early detection and early treatment. Coronary heart disease has long been confirmed due to the deposition of cholesterol in the coronary artery wall, the formation of atherosclerotic plaque blocking blood flow, angina pectoris, myocardial infarction. Therefore, 40 years ago in clinical trials began to determine the content of plasma total cholesterol in order to determine the possibility of inducing coronary heart disease. But a breakthrough contribution from theoretical research since 1977 proves that there are two kinds of cholesterol in plasma. One is low-density lipoprotein cholesterol (LDL-C), which is used by the bloodstream to various cells. Excess LDL-C is deposited in the cells and is the cause of atherosclerosis. It is “pathogenic LDL-C.” The other is high-density lipoprotein cholesterol (HDL-C), this cholesterol is the excess cholesterol in the surrounding tissue cells shipped to the liver through the blood circulation, with bile excretion
