Abstract:
OBJECTIVE:To study the effect and its possible mechanism of Xuezhiping capsule on blood lipid levels of high blood lipid model golden hamsters. METHODS:Golden hamsters were randomly divided into normal control group,model group, atorvastatin group (3 mg/kg),combination group (Xuezhiping capsule 1.3 g/kg+atorvastatin 1.5 mg/kg),Xuezhiping capsule low-dose,medium-dose,high-dose groups(Xuezhiping capsule 1.3,2.6,5.2 g/kg),10 in each group. Hamsters in normal control group received normal diet,the other groups were given high-fat diet to establish high blood lipid model. Then relevant drugs were intragastrically given 2 weeks later. Normal control group and model group were intragastrically given equal volume of distilled wa-ter,once a day,for 4 weeks. After last administration,blood lipid indexes(TG,TC,HDL-C,LDL-C,FFA),mRNA and protein expressions of lipid metabolism related genes (PPAR-α,CYP7A1,ACOX,SREBP-1c,ACC1) were detected. RESULTS:Com-pared with normal control group,serum contents of TC,TG,LDL-C,FFA in model group increased,HDL-C content decreased;PPAR-α,CYP7A1,ACOX mRNA and protein expressions were weakened,SREBP-1c,ACC1 mRNA and protein expressions were enhanced(P<0.05). Compared with model group,above-mentioned indexes were obviously improved in Xuezhiping capsule high-dose group,atorvastatin group and combination group (except for HDL-C in Xuezhiping capsule high-dose group)(P<0.05);TC,TG,FFA contents,and PPAR-α,CYP7A1,ACOX,ACC1 mRNA,and CYP7A1,SREBP-1c,ACC1 protein were obviously improved in Xuezhiping capsule medium-dose group(P<0.05);TC,TG contents,and PPAR-α mRNA,and CYP7A1, SREBP-1c protein were obviously improved in Xuezhiping capsule low-dose group (P<0.05). CONCLUSIONS:Xuezhiping cap-sule has a promising effect of lowering blood lipid,the mechanism may be related to activating PPAR-α and inhibiting SREBP-lc signaling pathway.
