Objective:To discuss dominant symptoms and compatibility rules of Dazhui(GV14) based on data mining.Methods:Literature related to Dazhui (GV14) was retrieved from CNKI, Wangfang, VIP, China Biomedical Literature Database (CBM) and Pubmed databases from January 1, 2012 to August 15, 2022, and the main symptoms of Dazhi (GV14) and the compatibility of acupoints were summarized. Gephi 0.9.5 software was used for complex network analysis to compare the treatment for dominant symptoms with single acupoint of Dazhi (GV14) and the compatibility of the acupoint. SPSS Modeler 18.0 software was used to analyze the association rules of acupoint combination based on Apriori algorithm. The clustering analysis of high frequency acupoints was carried out by SPSS Statistics 26.0 software.Results:A total of 722 articles were included, involving 732 prescriptions. The dominant symptoms of single acupoint were cervical spondylosis, acne, and cold; the treatment for dominant symptoms with compatibility included 14 types, such as cervical spondylosis, allergic rhinitis, ischemic stroke sequelae. The meridian compatibility was dominated by bladder meridian, and the frequency of yang meridians was higher than yin meridians. The compatibility of specific acupoints such as Xiahe acupoint, Beishu acupoint and Bahui acupoint were the main acupoints, and the high frequency acupoints were 33 acupoints such as Feishu (BL13), Baihui (GV20), Fengchi (GB20) and Zusanli (ST36), obtaining 4 series and 8 types of compatible combinations of Dazhui (GV14).Conclusions:Dazhui (GV14) is widely used in the treatment of internal diseases, such as respiratory diseases, nervous system diseases and vertebral artery type of cervical spondylosis. It tends to be flexibly used with multiple compatibility and clustering combination of specific acupoints.

Objective:To analyze the relevant records of Taibai (SP3) in ancient literature based on data mining technology; To summarize its application law.Methods:Ancient book materials included in the Zhong Hua Yi Dian (5th edition) were retrieved. Relevant information of Taibai (SP3) such as main treatment syndrome and compatibility of acupoints was extracted, and a database was established. The frequency of the data was counted. Gephi 0.10.1 software and SPSS Statistics 21.0 statistical software were used to carry out visualization analysis and clustering analysis on data. Results:A total of 248 articles were included, involving 43 ancient books, including 65 prescriptions for single acupoint application and 183 prescriptions for compatibility application. The main treatment of Taibai (SP3) involved internal medicine, surgery, gynecology and infectious diseases. There were 35 kinds of main treatment of single acupoint, and 12 kinds of dominant diseases, including vomiting, fever and dysentery. There were 47 kinds of main diseases and 14 kinds of dominant diseases such as fever, heartache and constipation. There were 138 acupoints, most of which were specific acupoints, mainly the spleen meridian, and the high frequency acupoints were Zusanli (ST36), Dadu (SP2), Gongsun (SP4) and so on. Clustering analysis obtained 8 kinds of acupoint combinations, which were potential prescriptions for Taibai (SP3).Conclusion:Taibai (SP3) was widely used in clinical practice in ancient times, with 8 kinds of diseases such as fever, constipation and abdominal pain as the main dominant diseases, and most of them were compatible with specific acupoints such as Zusanli (ST36), Dadu (SP2), Gongsun (SP4).
