Objective To investigate the polymorphism of T cell receptor β chain variable region (TCRVβ) in peripheral blood of clinically isoiated syndrome (CIS) patients. To preliminarily predict the specific TCRVβ fragment of CIS and its diagnostic value for CIS. Methods Hospitalized patients of Beijing Xuanwu Hospital from September 2012 to March 2014, were divided into 2 groups including CIS group (experimental pateints, n=30) and normal control group (healthy volunteers, n=30). The routine immune indexes and expression of TCRVβ subfamilies were detected by flow cytometry. CELL Quest Pro 5.1 software was used to analyze 24 subfamilies of TCRVβ. Calculated the statistic of amplification rate, amplification number and amplification fraction of the total 24 subfamilies of TCRVβ. Results Compared to the normal control group, the quantitative expression of CD4+TCRVβ2, 4, 5.2, 5.3, 7.1, 8, 14, 17, 20, 21.3 and CD8+TCRVβ4, 14 were significantly expanded in CIS group, CD4+TCRVβ11 and CD8+TCRVβ9, 11 were significantly reduce
