[Objective]To summarize the academic experience of Professor FAN Yongsheng,one of the first national famous traditional Chinese medicine masters,in treating the damp-heat syndrome of rheumatism.[Methods]Through the follow-up study,collecting and organizing Professor FAN Yongsheng's clinical cases of damp-heat syndrome of rheumatism,combined with the relevant ancient books and literature,summarizing the academic experience of Professor FAN Yongsheng in the diagnosis and treatment of damp-heat syndrome of rheumatism by Sanjiao method,focusing on the theoretical origin of Sanjiao method,the division of upper,middle and lower Jiao,as well as the practice of the clinical evidence,and added with the evidence of the experimental cases for support.[Results]The term Sanjiao originated in Huangdi Neijing.ZHANG Zhongjing deepened the concept of the Qi transformation of Sanjiao.XUE Xue pioneered the syndrome differentiation of the Sanjiao framework in Treatise on Dampness and Heat.WU Jutong systematically established the Sanjiao syndrome differentiation system in Systematic Differentiation of Warm Diseases.Professor FAN Yongsheng believes that the etiology of rheumatism with damp-heat syndrome is mostly attributed to insufficient endowment,exogenous or endogenous damp-heat obstruction in the Sanjiao,which results in the evil of damp-heat disturbing the upper-Jiao,trapping in the middle-Jiao and injecting into the lower-Jiao.When treating the disease,the parts of the Sanjiao where the damp-heat is located should be recognized.The treatment according to Sanjiao should be applied respectively with"propagation and opening""clearing"and"osmosis",and at the same time,the overall situation should be taken into account,and the three methods are often used together to eliminate the damp-heat and facilitate the Sanjiao.Three clinical cases demonstrated significant efficacy:Case 1 involved damp-heat clouding the upper-Jiao,treated with heat-clearing,damp-resolving,lung-ventilating and cough-relieving methods;Case 2 featured with damp-heat lodging in the middle-Jiao,managed with heat-clearing,spleen-strengthening and liver-soothing therapies;Case 3 presented damp-heat diffusing to the lower-Jiao,addressed through heat-clearing,damp-draining and collateral-unblocking strategies.All cases achieved satisfactory clinical results.[Conclusion]Professor FAN Yongsheng's academic experience in treating damp-heat syndrome of rheumatism by flexibly utilizing the Sanjiao method,which is based on inheritance,provides a theoretical basis and practical paradigm for the clinical management of rheumatism with damp-heat syndrome and is worth promoting and applying in the clinic.
