[Effect of electroacupuncture and diet adjusting on insulin resistance in rats with nutrition obesity].
OBJECTIVE
To study the effects of electroacupuncture and diet adjusting on insulin resistance in rats with nutrition obesity, and the role of electroacupuncture and diet adjusting in the treatment of obesity.


METHODS
Obesity was induced in rats by high-fat diet. Rats with nutrition obesity were randomly divided into high-fat diet (HD) group, high-fat diet plus electroacupuncture (HA) group, normal diet (ND) group and normal diet plus electroacupuncture (NA) group, with another group of SD rats as normal control (NC). After 15 days, all the rats' body weight and length were measured, the Lee's index was calculated, and the levels of total cholesterol (TC), triglycerides (TG), free fatty acid (FFA), fasting plasma glucose (FPG), fasting insulin (FINS) and tumor necrosis factor-alpha (TNF-alpha) were detected.


RESULTS
Compared with the HD group, food intake, body weight and viscera fat weight of the rats with nutrition obesity in the HA group and the NA group were markedly reduced (P<0.05). The levels of blood serum TC, FFA and IR index in the NA group were obviously lower than those in the HD group (P<0.01). The levels of TNF-alpha and FINS in the NA group were lower than those in the HD group (P<0.05).


CONCLUSIONS
Electroacupuncture plus diet adjusting can decrease the levels of serum TNF-alpha and FINS of the obesity rats, and improve the state of insulin resistance.
