Abstract: Objective:To evaluate the possible role of cytokines in pathophysiology and treatment of nasal polyps.Method:The expressions of Th1-typed cytokines IFN-γ、IL-2 、IL-12 and Th2-typed cytokines IL-4、IL-5、IL-8、IL-10、IL-13 were investigated with enzyme-linked immune sorbent assay(ELISA) in 25 patients with nasal polyps.Result:There was a significant upregulation of Th2-typed cytokines IL-4、IL-5、IL-8、IL-10、IL-13 in nasal polyps compared with normal nasal mucosa, especially　IL-4 and IL-5 (3.9 times and 8.8 times higher than normal mucous respectively) while the expression of Th1-typed cytokines IFN-γ、IL-2、IL-12 drcreased after treated with local glucocorticoid. The levels of Th2-typed cytokines decreased significantly and Th1-typed cytokines had no obvious change.Conclusion:The upregulation of Th2-typed cytokines such as IL-4、IL-5、IL-8、IL-10、IL-12 may play an important role in the pathophysiology of nasal polyps and Th2-typed cytokines can be viewed as a target of treatment to nasal polyps.
