RESUMO
Based on the set visualization analysis system and Apriori algorithm, the acupoint selection rule for the treatment of postpartum hypogalactia with acupuncture and moxibustion was explored. The clinical research articles relevant with postpartum hypogalactia treated with acupuncture and moxibustion were retrieved from CNKI, Wanfang and VIP databases till July 15, 2019 since the database establishment. According to the inclusion and exclusion criteria, the articles were screened and the acupoint prescriptions were extracted. On the base of the set visualization analysis system and Apriori algorithm, the characteristics of acupoints and the common acupoint combination were analyzed for the treatment of postpartum hypogalactia with acupuncture and moxibustion. Totally, 120 articles are included and 72 acupoints are extracted for the treatment of postpartum hypogalactia with acupuncture and moxibustion, of which, the conception vessel and the stomach meridian of foot-yangming are the most commonly used and the combination of Danzhong (CV 17), Rugen (ST 18), Zusanli (ST 36), Shaoze (SI 1) and Taichong (LR 3) is of the high frequency. The analyses of set visualization, acupoint association rule and acupoint combination network consistently indicate that the above mentioned 5 acupoints are the basic combination for the treatment of postpartum hypogalactia with acupuncture and moxibustion, co-acting on tonifying and nourishing qi and blood, smoothing liver qi and relieving stagnation, activating circulation and promoting lactation. This combination effectively treats postpartum hypogalactia caused by the source insufficiency of transformation of qi and blood and qi stagnation.
