Abstract:Objective: The aim of this study was to systematically summarize the syndrome differentiation and treatment thought of professor JIN Shi in treating chronic liver disease. Method: Medcase V3.2 storehouse and medical record national physician Maian data mining system was adopted to collect the typical cases of chronic liver disease treated by professor JIN Shi. Then frequency analysis and association rule analysis were used for data mining on symptoms, syndromes, pathogenesis and therapeutic principle. Result: There were 1 915 cases of chronic liver disease included, with chronic hepatitis B viral hepatitis the most disease (43.1%). Damp-heat-blood stasis-toxin and disorder of liver-spleen were the most frequent pathogenesis, accounting for 19.7% and 10.6% respectively;noxious heat stasis syndrome and damp-heat in liver-gallbladder syndrome were the most frequent syndrome, accounting for 22.6% and 19% respectively;regulating liver and activating spleen, clearing heat and damp, were the most common therapeutic principle, accounting for 12.2% and 8.2%, respectively. Conclusion: Noxious heat stasis syndrome and damp-heat in liver-gallbladder syndrome were the most frequent syndrome for chronic liver disease treated by professor JIN Shi, who valued the pathogenesis of damp-heat-blood stasis-toxin. The common therapies for chronic liver disease were regulating liver and activating spleen, and in the assistance of syndrome differentiation based adjuvant therapy, it can be applied to clear heat and damp, detoxify and disperse blood stasis, which can be generalized to clear, soothe, activate, dissolve and tonic.
