Both the blank control group and the model group were given 0.9% normal saline by gavage. The low,medium,and high-dose groups of Soufeng Qutangroup and the atorvastatin group were given different doses of Soufeng Qutan Chinese Medicine Decoction and atorvastatin. After 13 weeks,the mice were sacrificed,and the abdominal aortic blood vessels were observed by HE staining. Total cholesterol(TC),triglycerides(TG),low-density lipoprotein cholesterol(LDL-C). and high-density lipopro?tein cholesterol(HDL-C)content were detected by a biochemical automatic analyzer and IL-1β levels were detected by ELISA.Results:Compared with the blank control group,a large number of foam cells could be seen in the model group with obvious plaques;serum TC,TG,LDL-C,and IL-1β levels were significantly increased(P<0.05),and HDL-C level was markedly de?creased (P<0.05). Compared with the model group,the Soufeng Qutangroup at all doses and the atorvastatin group had a small amount of foam cells and reduced plaque area;serum TC,TG,LDL-C,and IL-1β levels were significantly decreased (P<0.05),and the level of HDL-C was significantly increased (P<0.05).Conclusion:Soufeng Qutan Chinesemedicine can inhibit the pro?gression of cellular inflammation,downregulate the expression of IL-1β,reduce plaques,and improve blood lipids. This may be one of the molecular mechanisms of Soufeng Qutan Chinese medicine in the early treatment of atherosclerosis.展开更多
