& To date, the complete mechanism of rheumatoid arthritis (RA) remain unclear, T cells have been proposed to play an important role in the disease initiation and progression. Presently, some researchers have reported that there were skewed TCR Vb in different samples of experimental animals or RA patients, such as in the peripheral blood, joints or synovial fluid, however, most of the results were not coincident or even conflict with each other. In this article, with real-time fluorescence quantitative PCR with DNA melting curving technique, we detected the bias of TCR Vb of RA patients, and found that although most of TCR Vb usage were different between peripheral blood and synovial fluid, the overview of all the Vb skewness was similar between the two samples.

INTRODUCTION Rheumatoid arthritis (RA) is a chronic inflammatory diseases characterized by destructive polyarthritis. Although the complete mechanism of RA remain unclear, T cells have been proposed to play an important role in the disease initiation and progression.[1,2] Mature T cells express one of two types of T cell receptors (TCRs): a heterodimer of a and b chains or c and d chains. In animal models with collagen-induced arthritis (CIA), Corthay[3] found that ab T cells play a more important role in the occurrence of RA than that of cd T cells.

CIA, researchers[4,5] found that there were TCR variable beta (Vb) genes over-expressed; moreover, accompanied by the development of the disease, some Vb families exhibited certain advantage clonetypes. In the studies on human patients with RA, T lymphocytes were considered undergoing expansion in the synovium, especially, some of TCR gene showed skewness in the joints and blood of RA patients.[6,7] If the biased TCR Vb was associated with the pathogenic T-cell populations, the corresponding TCR elements could be targeted by TCR-specific immunotherapies, such as TCR peptide vaccination or T-cell vaccination.[8,9] Unfortunately, many contradictory findings have been reported, moreover, although there are several reports relate to the bias of TCR Vb in RA patients, seldom reports focused on comparative analysis of TCR Vb gene usage of peripheral blood (PB) and synovial fluid (SF) of RA patients. More presently, real-time florescence quantitative polymerase chain reaction (FQ-PCR) and DNA melting curve analysis technique was successfully modified and used to detect the skewness of TCR.[10] In this study, we used real-time RQ-PCR and melting curve analysis technique to assay the TCR Vb gene usage of PB and SF of acute and chronic RA patients, to further analyze the clone features of these two samples, and hope to provide information for the study of mechanism. OBJECTS AND MEHTODS Screening for Controls and RA Patients Twelve healthy volunteers for providing PB samples were recruited form Health Examination Center, three patients who were operated on knees and provide SF samples came form surgery wards. All RA patients (detail information shown in Table 1) were screened according to the diagnostic criteria of the American Rheumatism Association.[11] All of objects had not been treated with immunomodulating drugs in the previous six months prior to the study and were seronegative for markers of hepatitis viruses, HIV and other pathogenic infections. Excluded from the study were
