Abstract:
Objective To investigate the effect of electroacupuncture at point Fenglong(ST40) on the expressions of macrophage surface antigen CD11b and intercellular adhesion molecule-1 (ICAM-1) in hyperlipidemia rats. Method Forty healthy SD rats were randomly allocated to normal control, high fat diet, high fat+common diet, high fat diet and treatment, and high fat+common diet and treatment groups. After 28 days of treatment with electroacupuncture at point Fenglong, blood lipid levels, namely, total cholesterol (TC), triglyceride (TG), low density lipoprotein cholesterol (LDL-C) and high density lipoprotein cholesterol (HDL-C) contents were measured in every group of rats. The expressions of peritoneal macrophage surface antigen CD11b and ICAM-1 were examined using flow cytometry (FCM) in every group of rats. Result Plasma TC and LDL-C increased significantly in the high fat diet group of rats compared with the normal control group (P<0.01). In the high fat+common diet group of rats, serum TC and LDL-C decreased significantly in comparison with the high fat diet group (P<0.01) but increased significantly in comparison with the normal control group (P<0.01). After treatment with electroacupuncture at point Fenglong, rat plasma TC and LDL-C decreased significantly (P<0.01) and TG and HDL-C did not change significantly (P>0.05). The expression rates of macrophage CD11b and ICAM-1 increased significantly in the high fat diet group of rats compared with the normal group (P<0.01). In the high fat+common diet group of rats, the expression rates of macrophage CD11b and ICAM-1 decreased significantly in comparison with the high fat diet group (P<0.05) but increased significantly in comparison with the normal group (P<0.01). The expression rates of CD11b and ICAM-1 decreased significantly in the high fat diet and treatment group compared with the high fat diet group (P<0.01) and decreased significantly in the high fat+common diet and treatment group compared with the high fat+common diet group (P<0.01) and the high fat diet and treatment group (P<0.01). Correlation analysis showed that CD11b and ICAM-1 levels had a significantly positive correlation (r=0.947, P<0.01). Conclusion Electroacupuncture at point Fenglong can significantly down-regulate blood fat TC and LDL-C levels and the expressions of macrophage CD11b and ICAM-1 in hyperlipidemia rats. It has a certain therapeutic effect on hyperlipidemia.
