Objective: To analyze the rules of acupoint selection in the treatment of gastroesophageal reflux disease in China using data mining technology.
Methods: The published literature of treating gastroesophageal reflux disease with acupuncture was retrieved from electronic databases from January 1, 1983 to December 1, 2019, including SinoMed, CNKI, Wanfang and VIP database. Acupuncture prescription database was established, and the rules of acupoint selection were explored by statistical software SPSS 20.0 and SPSS Modeler 18.0.
Results: A total of 92 articles were included into this analysis, involving 92 acupuncture prescriptions, 76 acupoints. The total frequency of using these acupoints reached 549 times. Zhongwan (CV 12) was the most frequently used acupoint; the often selected meridians were conception vessel, stomach meridian, governor vessel, bladder meridian; the acupoints located at the abdomen, lower limbs and back were commonly selected; crossing points in the specific acupoints were commonly selected; the most frequently used group was Zusanli (ST 36)-Zhongwan (CV 12) and Neiguan (PC 6).
Conclusion: Treating gastroesophageal reflux disease by acupuncture in China is dominated by shu-mu point combination, supplemented by mu-he point combination; yin meridians are emphasized as much as yang meridians; using specific acupoints is advocated, especially the crossing points.
目的：运用数据挖掘技术分析国内针刺治疗胃食管反流病的选穴规律。方法：检索1983年1月1日至2019年12月1日中国生物医学文献数据库（SinoMed）、中国期刊全文数据库（CNKI）、万方数据知识服务平台（Wanfang）、维普中文期刊服务平台（VIP）针刺治疗胃食管反流病的相关文献，建立针灸处方数据库，运用SPSS 20.0、SPSS Modeler 18.0软件进行统计分析，探究腧穴选用规律。结果：共纳入92篇文献，涉及92个针灸处方、76个腧穴，腧穴使用总频次549次。中脘使用频次最高，常选用经脉为任脉、胃经、督脉、膀胱经，腹部、下肢和背部腧穴使用较多，特定穴多使用交会穴，最常用的腧穴组合为足三里-内关、中脘。结论：国内针刺治疗胃食管反流病以俞募配穴为主，募合配穴为辅；阴、阳经并重；重视特定穴使用，尤其是交会穴。.
