本文旨在了解健康人与冠心病(CHD)患者的血清,对各种培养的血管细胞尤其是内膜内皮下细胞,是否能引起细胞脂质水平的增高。方法供血者分三组:CHD 组68例,无冠状动脉狭窄的胸痛患者13例,健康组42例,从肘静脉取血后用超速离心法制备去脂蛋白血清。培养细胞取 This article aims to understand the health of patients with coronary heart disease (CHD) serum, a variety of cultured vascular cells, especially endometrial subendothelial cells, can cause increased cellular lipid levels. Methods Blood donors were divided into three groups: 68 patients in CHD group, 13 patients with chest pain without coronary stenosis, and 42 healthy people. Blood was drawn from elbow vein and then the serum was prepared by ultracentrifugation. Culture cells to take
