Abstract：Objective To explore B cells and natural killer(NK)cells changes in pefipheral blood of rheumatoid arthritis(RA)patients to understand the role of the changes in RA patients and inflammation activities of disease.Methods All the RA patients selected into this study were divided into different disease activity group according to Disease Activity Score(DAS28).The peripheral blood mononuclear cells were cultured in vitro.The lymphocytes were marked by four-color fluorescent antibody of CD3/CD4/CD8/CD19 and CD16/CD3/CD19/CD56,and then detected lymphocyte by flow cytometry.We markered and detected the number of the T phenotype cells,B phenotype cells,NK phenotype cells.The correlation between the lymphocyte and diseases activity score,tenderness joint swelling of the joints number,morning stiffness time,doctors and patients to disease activity glogal assessment(VAS),red blood cell subsidence ratio,C.reactive protein and serological antibody was analyzed.Results The proportions of the CD3-CD19+cell and the CD3-CD16+CD56+cell in peripheral iymphocytes was(12.09±3.47)%and(15.02±2.56)%respectively in RA group.Correlation analysis indicated significant negative correlations of the proportions of CD3-CD19+cells with DAS28-4 and a-ccp(P<0.05).Furthermore,CD3+CD19-and CD1-CD19+ cells still showed significant correlation between with pSS and ILD and without(P<0.05).Conclusion There is an imbalance in the proportions of the CD3-CD19+cell and the CD3-CD16+CD56+cell in peripheral iymphocytes with RA.The abnormality of iymphocytes may be a coincidence in the inflammation and infection in patients with RA.
