The aim of the current study was to evaluate the expression levels of STAT6, VEGF and microvessel density (MVD) score in nasal polyp tissues and to explore the underlying relationships during the pathogenesis of nasal polyps. 40 cases with surgical removal of nasal polyps were included, comparing with control group of 10 inferior turbinate mucosal tissues resected from nasal septum deviation correction surgery, from the same time period. By immunohistochemistry, the protein expression levels of STAT6, VEGF and MVD were determined. The results showed that the positive expression rate of STAT6 in mucosal epithelium and glands of nasal polyp tissues was 70%, which was significantly higher than that in control group (P < 0.01). The positive expression percentage of VEGF was 75%, which also higher than that in control group (P < 0.01). The MVD values in nasal polyp group was 22.67±7.54, while 7.04±2.63 in control group. The expression of STAT6 was closely related with the expression of VEGF and MVD, increasing with the level of VEGF and MVD. In general, the expression levels of STAT6, VEGF and MVD in nasal polyp group were increased and themselves were positively correlated, indicating the significant importance in the development of nasal polyp.
