2020, 43 (1):
Objective To provide a reliable basis for the diagnosis and standardized treatment of rheumatoid arthritis by summarizing its patterns and pattern elements. Methods Cases of the inpatients and outpatients from May 2016 to December 2017 in the rheumatology department of the First Hospital of Hunan University of Chinese Medicine were collected, and the included cases were analyzed for pattern analysis and pattern element extraction, and their clinical characteristics were analyzed. Results A total of 12 patterns were obtained in 217 patients diagnosed as rheumatoid arthritis, which were divided into 5 pattern elements of disease locations and 10 pattern elements of disease characters. Clinical common patterns from high to low were liver-kidney deficiency, dampness-heat obstruction, cold-dampness obstruction, qi-blood deficiency, phlegm and blood stasis obstruction, cold-heat complex, wind-dampness obstruction, qi-yin deficiency, pattern elements of disease locations from high to low were meridians and channels, kidney, liver, spleen, superficies, and pattern elements of disease characters from high to low were dampness, heat, cold, qi deficiency, blood deficiency, blood stasis, phlegm, wind, yin deficiency, yang deficiency. Conclusion Liver-kidney deficiency, dampness-heat obstruction, cold-dampness obstruction are the common patterns of rheumatoid arthritis; and meridian, kidney, liver, dampness, heat, cold are the common pattern elements. Establishing pattern differentiation system with pattern elements as the core could play a role of controlling complexity in clinical diagnosis and treatment of rheumatoid arthritis.
