OBJECTIVE@#To investigate the B lymphocytes(CD20) and T-lymphocyte subsets (CD4, CD8) expression and clinical significance in chronic rhinosinusitis.@*METHOD@#Immunohistochemical technique was applied to detect the expression of the B lymphocytes (CD20), helper T lymphocytes (CD4) and the cytotoxic T lymphocyte (CD8) in 15 patients with chronic rhinosinusitis without nasal polyps group (CRSsNP). 12 patients of chronic nasal sinusitis with nasal polyp (CRSwNP), 7 cases of recurrent CRSwNP group and 13 patients with inferior turbinate mucosa in the control group. The Mann-Whitney U test was used to analyze CD)20, CD4 and CD8 between the experimental groups and the control group. One- Way ANOVA was used to compare the lymphocyte infiltration between the experiment groups.@*RESULT@#Patients with CRS had higher infiltration of the B lymphocytes (CD20) and T lymphocyte subsets (CD4, CD88) than the patients of the control group (P < 0.05). The expression of T lymphocyte subsets (CD4, CD8) in CRSwNP and recurrent CRSwNP groups was significantly higher than in CRSsNP (P < 0.05). The expression of CD4 in the recurrent CRSwNP group was obviously higher than that in CRSsNP and CRSwNP (P < 0.01).@*CONCLUSION@#The B lymphocytes, helper T cells and cytotoxic T cells have the high expression in CRS groups, which involved with the formation of inflammation. Furthermore nasal polyps are closely related to T lymphocyte infiltration.
