    Abstract:
    OBJECTIVE: To observe the effect of electroacupuncture (EA) on expression of hypothalamic sirtuin 1(SIRT1) and proopiomelanocortin (POMC), and body weight, food-intake, blood glucose, and blood lipid levels in obese rats, so as to explore its mechanisms underlying improvement of obesity. METHODS: Forty male Wistar rats were randomly divided into normal, model, EA, and sham EA groups (n＝10 rats in each group). The obesity model was established by feeding the rats with high fat diet. EA (2 Hz, 1 mA) was applied to "Zusanli" (ST36), "Zhongwan" (CV12), "Guanyuan" (CV4) and "Fenglong" (ST40) or sham acupoints (about 5 mm beside each acupoint, shallow needling) for 20 min, once every other day for 8 weeks. The rats' body weight and food-intake were recorded. The blood glucose (fasting plasma glucose: FPG, postprandial plasma glucose: PPG) and blood lipids (triglyceride: TG, total cholesterol: TC, non esterified fatty acid: NEFA) were assayed by using an automatic biochemical analyzer. The protein and mRNA expression levels of SIRT1 and POMC in the hypothalamus were detected by Western blot and quantitative real-time PCR, respectively. RESULTS: In comparison with the normal group, the body weight, food-intake, blood lipids, and PPG levels were significantly increased (P<0.05，P<0.01), and the expression levels of SIRT1 protein and mRNA in the hypothalamus were significantly doun-regulated in the model group (P<0.05). Following EA, the body weight, food-intake, blood lipids, and PPG levels were considerably down-regulated (P<0.01，P<0.05), and the expression levels of SIRT1 and POMC protein and mRNA in the hypothalamus were significantly up-regulated in the EA group rather than those in the sham EA and the model groups (P<0.05)．. CONCLUSION: EA can reduce the obese rats' body weight, food-intake, blood lipids and blood glucose, which may be associated with its effect in up-regulating the SIRT1 and POMC expression of hypothalamus.
