Objective To approach the joint function degree of rheumatoid a rthritis（RA） and its relationship between TCM syndromes according to the imagin g.Methods Joint function classification

X-ray stagin g and TCM syndromes were p erformed on 150 RA patients.The relationship between the joint function classif ication with X-ray staging and TCM syndromes was analyzed respectively.Results There existed positive correlation between the joint function classification wit h X-ray staging in RA patients（P<0.01）.The difference between damp-heat impedi ng syndrome with kidney qi deficiency cold syndrome and liver-kidney yin deficiency s y ndrome was statistically significant（P<0.01）.The difference between cold-damp impeding syndrome with kidney qi deficiency cold syndrome and liver-kidney yin deficiency syndrome was statistically significant as well（P<0.01）.The joint func tion classification of damp-heat impeding syndrome and cold-damp impeding syndrome wa s almost grade I or gradeⅡ

while kidney qi deficiency cold syndrome and liver-ki dney yin deficiency syndrome was almost grade Ⅱ or grade Ⅲ.Concl usion There is positive correlation between the joint function classifications with X-ray stagin g.Grade Ⅲ distributed widely in the kidney qi deficiency cold syndrome and liver-k idney yin deficiency syndrome

while narrowly in damp-heat impeding syndrome and c old-damp impeding syndrome.
