[Study on medication laws of Tibetan medicine in treatment of plateau disease based on data mining technology].

Traditional Chinese medicine inheritance support system (TCMISS, V2.5) was used in this study to analyze the common medicines, frequency of medicine combination, core herbal combinations and new prescriptions for the treatment of plateau disease from the Four-Volume Medical Code, Mannose Herbal Mirror and other related books. TCMISS V2.5 software was used to construct the database of drug treatment for plateau disease. The frequency analysis and association rules apriori algorithm, improved mutual information method and other data mining methods were used to explore the law of drug compatibility. After the analysis of 531 prescriptions for plateau disease, 20 common symptoms of plateau disease were summarized such as insomnia and tinnitus. There were 539 kinds of herbs in the plateau disease prescriptions, including 33 kinds of herbs whose medicinal frequency>=50, such as Terminalia chebula and Myristica fragrans, and T. chebula had the highest medicinal frequency; 14 commonly used herbal combinations, and "Aucklandia lappa-T. chebula" had the highest frequency; 13 core herbal combinations were obtained after entropy clustering analysis, including 8 combinations of three herbs such as "Allium sativum-Carum carvi-Ferula sinkiangensis" and 5 combinations of four herbs such as "A. lappa-Aquilaria sinensis-Ewgewia caryophyllata-Myristica fragrans", and 5 new prescriptions such as "A. sativum-C. carvi-F. sinkiangensis-A. lappa-Choerospondia axillaris-A. sinensis-M. fragrans". The main symptom of "insomnia" was chosen to analyze the treatment of insomnia, and the core herbal combinations mainly including A. sinensis, T. chebula, and C. axillaris as well as the new prescriptions mainly containing Carthamus tinctorius, Meconopsis horridnla, and Punica granatum were obtained. The prescriptions for the treatment of plateau disease were clarified by TCM inheritance system, and the clinical prescription regularity and characteristics of the combination of common medicines were summarized, to provide reference and new ideas for its clinical application and development of new drug research.
