Methods Serum bilirubin was determined with Malloy Evelyn. Total cholesterol(TC),triglycerides(TG) and high density lipoproteins(HDLc)were determined with enzymology,low density lipoprotein(LDLc) was calculated with the formula that LDL=TC (TG/5+HDLc).

• 方法 采用重氮盐终点法测定血清胆红素 ,酶法测定总胆固醇 (TC)、甘油三酯 (TG)及高密度脂蛋白胆固醇 (HDLc) ,低密度脂蛋白胆固醇 (LDLc)则通过估计法 (公式为LDL =总胆固醇 甘油三酯 /5 +高密度脂蛋白胆固醇 )计算获得。
