title: [Effect of acupuncture on serum leptin level in patients with type II diabetes mellitus].
abstract: OBJECTIVE
  To study the relationship between serum leptin and insulin resistance, and to analyze the effect of acupuncture on serum leptin level in patients with type-II diabetes mellitus (DM).
  
  
  METHODS
  A total of 80 type-II DM patients were randomized into acupuncture and medication groups. Acupuncture was applied to Yishu (EX), Feishu (BL13), Pishu (BL 20), etc. according to syndrome identification. The treatment was given once every other day for 12 weeks. For patients in the medication group, Glibenclamide (2.5-7.5 mg/time, 1-2 times/d according to blood sugar level) was given for 12 weeks. Fasting blood glucose (FBG), fasting insulin (FINS) and fasting leptin (FLP) were detected by using glucose oxidase method, radioimmunoassay and ELISA, respectively. Insulin sensitivity index (ISI) and homeostasis model assessment-insulin resistance (HOMA-IR) were calculated.
  
  
  RESULTS
  In comparison with pre-treatment, FBG levels and HOMA-IR in both acupuncture and medication groups, and FINS and FLP levels in the acupuncture group were decreased significantly (P < 0.01), while ISI in both acupuncture and medication groups, and FINS level in the medication group were increased remarkably after the treatment (P < 0.01). Comparison between two groups showed that after the treatment, FINS and FLP levels, and HOMA-IR of the acupuncture group were considerably lower than those of the medication group (P < 0.01), while ISI of the acupuncture group was significantly higher than that of the medication group (P < 0.01).
  
  
  CONCLUSIONS
  Acupuncture therapy is effective in lowering FLP level, which may contribute to its clinical effect in improving type-II DM.
