Objective:To analyze the literature characteristics and acupoint selection rules of acupuncture for primary insomnia of heart-spleen deficiency type by means of bibliometrics and data mining.Methods:Randomized controlled trial(RCT)literatures on acupuncture for primary insomnia of heart-spleen deficiency type,published from the establishment of databases to December 2022,were retrieved from China National Knowledge Infrastructure(CNKI),VIP Chinese Journal Database,Wanfang Data Knowledge Service Platform,PubMed and The Cochrane Library.A database was established for statistical analysis.The Apriori algorithm was used to conduct association rule analysis on acupoints and draw a co-occurrence network diagram,and SPSS 26.0 software was adopted for inter-group cluster analysis.Results:A total of 51 literatures were included,and the number of published literatures showed an overall upward trend,with most of them published in general journals.Fourteen different combinations of intervention measures were adopted,among which traditional acupuncture was the main one.The acupoints with high frequency of use were Shenmen(HT7),Sanyinjiao(SP6),Pishu(BL20),Xinshu(BL15)and Baihui(GV20).The meridians with the highest frequency of acupoint distribution were the Bladder Meridian of Foot-Taiyang.Most acupoints were distributed in the head and neck.Among the specific acupoints,crossing acupoints had the highest frequency of use.The acupoint group with the strongest correlation was Xinshu(BL15)-Pishu(BL20).Cluster analysis divided the acupoints into 5 effective clusters.Conclusion:Acupuncture for primary insomnia of heart-spleen deficiency type focuses on regulating the heart,tonifying the spleen and tranquilizing the mind.The core acupoint prescription includes Xinshu(BL15),Pishu(BL20),Shenmen(HT7),Sanyinjiao(SP6)and Baihui(GV20),which can provide a reference for clinical treatment.
