Abstract：Objective To study the change of T cell subsets in peripheral blood of patients with rheumatoid arthritis (RA) and investigate the significance of T cell 1 subsets change in the incidence and inflammatory activity of RA. Methods Four-color fluorescence flow cytometry was used to detect the CD3/CD8/CD45/CD4 and CD3/CD16 +56/ CD45/CD19 markers in the peripheral blood lymphocytes of 197 RA patients. The proportion of peripheral blood lymphocytes in RA patients was compared and correlation analysis was conducted between T cell subsets and disease activity indices which include disease activity score(DAS28-4) ,tender joint count (TJC) .swollen joint count(SJC) , time of morning stiffness, patient's global assessment of disease activity on a 100 mm VAS by doctor and patients, erythrocyte sedimentation rate, C-reactive protein and serum antibody. Results The proportions of CD3+CD19- , CD3+ CD4+ and CD3+ CD8+ T cells in peripheral lymphocytes were (71.06 ±12.07)% , (45.13 ±36.14)% and (26.56 ±9.54)% respectively in RA group. Correlation analysis indicated significant negative correlations of the proportions of CD3+ CD19- cells with DAS28-4, TJC, SJC and patient's global assessment of disease activity a 100 mm VAS by patients (P <0.05 ). Furthermore, CD3+ CD4+ T cells still showed significant negative correlation with the anti-CCP antibody (r =-0. 156,P =0. 029) , and no correlation with AKA, APF and RF. CD3+ CD19-and CD3+CD8 + T cells showed significant differences between the interstitial lung disease group and control group (Z=-2. 159 and -2.031, P= 0. 031 and 0.042). There was no significant difference between the Sj(o)gren' s Syndrome group and control group(P>0.05). Conclusion The proportion of T lymphocytes in peripheral blood of patients with RA and the abnormality of T lymphocytes may play an important role in the incidence and inflammatory activity of RA.
