Objective To observe the effect and explore the mechanism of acupuncture on hyperlipemia in mice. Methods One hundred and twenty male Kunming mice of clean grade were randomly divided into a normal group (40 mice), a model group (40 mice), an acupuncture group (20 mice), and a drug group (20 mice). The hyperlipidemia model was prepared in the latter 3 groups by feeding with high fat diet. After the successful modeling, bilateral "Fenglong" (丰隆 ST 40), "Quchi" (曲池 LI 11), and "Sanyinjiao" (三阴交 SP 6) were selected in the acupuncture group and Han's Acupuncture Stimulator was connected to intervent for 10 rain, once daily, for 10 successive days. Mice in the drug group were orally given Simvastatin, once daily, for 10 successive days. No intervention was given to the normal group and the model group. Serum contents of total cholesterol (TC), triglyeeride (TG), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), malondialdehyde (MDA), nitric oxide (NO), endothelin (ET), and the activity of superoxide dismutase (SOD) were detected. Results The serum contents of TG, TC and LDL-C in the model group detected on the 15th day were all higher than those of the normal group [(1.31±0.32) mmol/L vs (0.70±0.21) retool/L, (5.72±0.85) mmol/L vs (3.08±0.74) retool/L, (2.68±0.55) mmol/L vs (1.83±0.36) retool/L, respectively]. The serum content of HDL-C in the model group was lower than that in the normal group [(0.60±0.26) mmol/L vs (0.94±0.30) mmol/L], showing successful modeling. On the lOth day of successful modeling, the serum contents of MDA and ET in the acupuncture group were lower than those in the model group [(21.58±3.54) p, mol/mL vs (29.94±2.79) p, mol/mL, (44.51±5.23) pg/mL vs (67.07±11.98) pg/mL]. The serum SOD activities and NO content in the acupuncture group were higher than those in the model gropu [(264.57±14.46) U/mL vs (
