Abstract
To observe the effect of acupuncture of Feishu (BL 13), Pishu (BL 20), etc. on body weight, blood lipid, leptin (LP) and soluble leptin receptor (sOB-R) levels in prediabetic patients, so as to explore its mechanisms underlying treatment and prevention of prediabetes. A total of 100 prediabetic patients were randomly assigned to medication (Metformin) group (n＝35), acupuncture group (n＝35) and simple lifestyle intervention group (n＝30) with random number table method. All the patients of the 3 groups were treated with lifestyle intervention (reasonable diet and moderate physical exercise) and ordered to stop administration of any hypoglycemic drugs during the treatment period. Bilateral Feishu (BL 13), Pishu (BL 20), Weishu (BL 21), Shenshu (BL 23), Zusanli (ST 36) and Sanyinjiao (SP 6) were punctured with filiform needles which were manipulated by lifting, thrusting and twirling repeatedly for about 2 min every 5 min during 30 minutes' needle retaining. The acupuncture treatment was conducted once every other day for 12 weeks. Patients of the medication group were ordered to orally take Metformin tablets (0.5 g/time, twice a day) for continuous 12 weeks. Body mass index (BMI), waist circumference (WC), waist-to-hip ratio (WHR), 2 h-postprandial blood glucose (2 h-PBG), fasting blood glucose (FBG), glycosyla-ted hemoglobin (HbA1c), total cholesterol (TC), triglyceride (TG), fasting insulin (FINS), serum LP and sOB-R levels were measured before and after the treatment. After the treatment, the BMI in the acupuncture group, and BMI, WC and WHR in the medication group were significantly decreased relevant to their own pre-treatment in each group (P<0.05, P<0.01). Following the treatment, the levels of FBG, 2 h-PBG, HbA1C, TC, TG, FINS, HOMA-IR and LP in both acupuncture and medication groups, and FBG in the simple lifestyle intervention group were significantly decreased in comparison with their own pre-treatment in each group (P<0.01, P<0.05), and the levels of FBG, 2 h-PBG, HbA1C, TC and TG, HOMA-IR and LP in both acupuncture and medication groups were all considerably lower than those of the simple lifestyle intervention group (P<0.01，P<0.05). The level of FINS in the medication group was significantly lower than that of the simple lifestyle intervention group (P<0.05). Additionally, following the treatment, serum sOB-R contents in both acupuncture and medication groups were obviously increased compared with their own pre-treatment in each group and also relevant to the simple lifestyle intervention group (P<0.01). No significant changes were found in the simple lifestyle intervention group in all the above-mentioned blood indexes except FBG (P>0.05). Acupuncture can induce body weight loss, down-regulate FINS, insulin resistance and LP resistance, and up-regulate sOB-R content in prediabetic patients, displaying a positive role in the treatment of prediabetes.
