[Effect of electroacupuncture combined with intradermal needling on simple obesity and serum intestinal lymphatic function-related factors].Zhongguo Zhen Jiu. 2022 Sep 12; 42(9):966-70.ZZ
To assess the efficacy of the combined treatment with electroacupuncture (EA) and intradermal needling on simple obesity and explore its underlying effect mechanism.
A total number of 116 patients with simple obesity were randomized into an observation group (58 cases, 3 cases dropped off and 2 cases removed) and a control group (58 cases, 4 cases dropped off and 1 cases removed). Patients in the control group received EA at Zhongwan (CV 12), Quchi (LI 11), Zusanli (ST 36), Pishu (BL 20), Weishu (BL 21), etc., for 30 min each time. On the base of the intervention as the control group, the patients in the observation group received the intradermal needling at Tianshu (ST 25), Daheng (SP 15), Zusanli (ST 36), Shangjuxu (ST 37), Quchi (LI 11), Pishu (BL 20) and Weishu (BL 21). In each group, the intervention was given once every two days, 3 times a week, consecutively for 3 months. Before and after treatment, the obesity indexes (body mass [BW], body mass index [BMI], body fat percentage [F%], adiposity [A] and waist circumference [WC]), the serum intestinal lymphatic function-related factors (vascular endothelial growth factor C [VEGF-C], delta-like ligand 4 [DLL4], adrenomedullin [ADM]), blood lipid (total cholesterol [TC], triglyceride [TG] and low density lipoprotein-cholesterol [LDL-C]), and fasting plasma glucose (FPG), fasting insulin (FINS) and insulin resistance index (HOMA-IR) were observed in the patients of both groups; and the efficacy was assessed.
The effective rate was 88.7% (47/53) in the observation group, higher than 71.7% (38/53) in the control group (P<0.05). After treatment, except FPG in the control group, BW, BMI, F%, A, WC, and the concentrations of serum VEGF-C, DLL4 and ADM, as well as TC, TG, LDL-C, FBG, FINS and HOMA-IR were all reduced compared with those before treatment in both groups (P<0.05). The reduction ranges of BW, BMI, F%, A, WC, and the concentrations of serum VEGF-C, DLL4 and ADM, and TC, LDL-C, FINS and HOMA-IR in the observation group were all larger than those in the control group (P<0.05).
Electroacupuncture combined with intradermal needling can reduce body weight and lipid, and improve insulin resistance in treatment of simple obesity, which is achieved probably through inhibiting lymphangiogenesis and promoting lymphatic endothelial permeability.
