[Animal model analysis of rheumatoid arthritis based on clinical characteristics of Chinese and Western medicine].

Rheumatoid arthritis(RA) is an autoimmune disease involving multiple joints bilaterally with symmetrical polyarthritis as the main symptom. The high disability rate of this disease seriously affects the quality of life of patients and even threatens their lives. The establishment of a good animal model is of great significance for the diagnosis and clinical prevention of RA. Based on the clinical characteristics of RA in traditional Chinese and Western medicine, the common animal models of RA were summarized, including drug-induced, gene-related, and syndrome and disease combined models. Joint swelling, pain, redness, nodules, and joint deformity are the main criteria for model evaluation, which have certain differences from the clinical diagnostic criteria of RA. From the perspective of syndrome differentiation, the animal model combining syndrome and disease only simulates the syndrome of traditional Chinese medicine and has no direct causal relationship with the formation of RA. In this paper, we analyzed the advantages and disadvantages of animal models of RA and the coincidence degree of the models with the clinical characteristics and then put forward the corresponding recommendations for the evaluation and improvement of these models, aiming to make the animal models of RA closer to the clinical symptoms and play an important role in the clinical diagnosis and treatment of RA.
