Methods： Thirty-seven patients with hyperlipidemia were randomized to treatment with Hedan Tablet 4.38 g/day as Hedan group（18 cases） or placebo（19 cases） as control group for 8 weeks. The lipid profile, PCSK9 and HDL subfractions were determined at day 0 and week 8 in both groups respectively. Results： Hedan treatment for 8 weeks mildly decreased serum low-density lipoprotein cholesterol（LDL-C） levels, while no changes were found in total cholesterol（TC）, triglycerides（TG） and PCSK9 concentrations. Furthermore, Hedan treatment increased the concentration of large high-density lipoprotein cholesterol（HDL-C） and the percentage of large HDL subfraction, while decreased the concentration of small HDL-C and the percentage of small HDL subfraction without changing serum HDL-C levels in patients with hyperlipidemia. Conclusion： Hedan treatment of 4.38 g per day for 8 weeks could confer a favorable effects on serum LDL-C concentration as well as HDL subfractions.展开更多

Forage with cholesterol and lipid plus 1.59 g/kg of YSTZT was fed to Group A every day;for Group B, 22.54 mg/kg gypenoside tablet was added to forage with cholesterol and lipid; for Group C, hyperlipid forage was given and for Group D, only ordinary forage was given. Biochemical parameters were measured and pathomorphological examinations were carried out 6 weeks later.Results: (1) YSTZT obviously lowered the levels of serum total cholesterol(TC), triglyceride(TG), atherosclerotic index(AI), apoprotein(ApoB), lipoprotein [Lp(a)], oxygen low density lipoprotein cholesterol(ox LDL), hydroxyproline(HYP), plasma Ca 2+ , thromboxane B 2(TXB 2), and increased the levels of serum high density lipoprotein cholesterol(HDL C), apoprotein A 1(Apo A 1), ApoA 1 /ApoB, plasma 6 keto PGF 1α ( P <0.01). (2) Pathomorphological examination showed that in Group A aortic intimal atherosclerotic plaque area and arterial intima thickness were obviously reduced, smooth muscle cell hyperplasia and elastic fibers were not seen.Conclusion: YSTZT can inhibit experimental hyperlipemia and atherogenesis. It is an ideal and effective medicine in preventing and treating hyperlipemia and atherosclerosis.展开更多
