ABSTRACT
<p><b>OBJECTIVE</b>To analyze the core acupoints and compatibility of electroacupuncture (EA) for simple obesity based on complex network technique, and to explore the usage of EA waveform.</p><p><b>METHODS</b>The clinical research literature regarding EA for simple obesity published from January of 1980 to June of 2016 were searched in PubMed, CNKI, , VIP, CBM and TCM online database to establish a prescription database of EA for simple obesity. The Matlab2014a software was used to perform the center analysis and cluster analysis, and the analysis of core points and compatibility were conducted. Gephi 9.1 software was used to demonstrate the complex network diagram to further analyze the usage of EA waveform.</p><p><b>RESULTS</b>Totally 238 prescriptions were obtained. The selection of acupoints at -meridians were equally important with acupoints at -meridians. The meridians with highest core degree were stomach meridian, conception vessel and spleen meridian. The acupoints with highest core degree were Sanyinjiao (SP 6), Tianshu (ST 25) and Zusanli (ST 36). The cluster analysis indicated three acupoint clusters, including the key-acupoint cluster, syndrome-acupoint cluster, and -point cluster; it was revealed Tianshu (ST 25) and Zhongwan (CV 12) had the highest intensity of compatibility. The sparse-dense wave was mostly used in EA for simple obesity, followed by continuous wave, indicating both sparse-dense wave and continuous wave had high clinical application value.</p><p><b>CONCLUSION</b>The acupoints of EA for simple obesity are mainly in stomach meridian, conception vessel and spleen meridian; sparse-dense wave is mostly used, followed by continuous wave.</p>
