Abstract:
OBJECTIVE To study the effects of Tibetan medi cine Shanhu qishiwei pill in lowering blood lipid of hyperlipidemia（HLP）model rats ，and to explore its mechanism primarily. METHODS According to their body weigh ，60 SD rats were randomly divide into normal group ，model group ，simvastatin group （positive control ，20 mg/kg）and Shanhu qishiwei pill low-dose，medium-dose and high-dose groups （50，100，200 mg/kg），with 10 rats in each group. Normal group was given conventional diet ，and other groups were given high-lipid diet to induce HLP model ，for consecutive 4 weeks. Administration groups were given relevant medicine intragastrically at the same time of modeling ；normal group and model group were given equal volume of normal saline intragastrically ，once a day ，for consecutive 4 weeks. After last administration ，the serum levels of TC ，TG， LDL-C and HDL-C were determined ；pathological changes of liver tissue were observed ；the protein expressions of AMPK ， p-AMPK，LKB1，and HMGCR in liver tissue were detected in each group. RESULTS Low-dose，medium-dose and high-dose of Shanhu qishiwei pill could significantly reduce the serum levels of TC ，TG and LDL-C and protein expression of HMGCR in liver tissue（P＜0.05），while significantly increased serum level of HDL-C ，phosphorylation level of AMPK ，protein expression of LKB 1 in liver tissue in HLP model rats （P＜0.05）；the pathological changes of liver tissue in HLP model rats were improved to different extents. CONCLUSIONS Shanhu qishiwei pill can reduce the blood lipid level of HLP model rats ，and its mechanism may be related to inhibiting the transmission of LKB 1/AMPK signal pathway and regulating lipid metabolism.
