Expression and clinical significance of Eotaxin-3 in chronic rhinosinusitis with and without nasal polyps / 临床耳鼻咽喉头颈外科杂志

ABSTRACT

OBJECTIVE@#To investigate the expression and clinical significance of Eotaxin-3 in chronic rhinosinusitis with and without nasal polyps.@*METHOD@#The ethmoid inflammation mucosa of 15 cases diagnosed as chronic rhinosinusitis (sinusitis group), the nasal polyps in the middle meatus of 25 cases diagnosed as nasal polyps (nasal polyp group) and the ethmoid or uncinate process mucosa of 7 cases diagnosed as sinonasal non-inflamnatory diseases (control group), were collected as the research object. Eotaxin-3 expression was detected in the tissues by immunohistochemical SABC assay and the correlation between Eotaxin-3 and blood eosinophil counts was analyzed.@*RESULT@#Eotaxin-3 were detected both in sinusitis group and nasal polyp group, and the expression level in sinusitis group and nasal polyp group were higher than that in control group. The difference was statistically significant (P < 0.05). The Eotaxin-3 expression in nasal polyps group was higher than that in sinusitis group, and the difference was statistically significant (P < 0.05). The expression of Eotaxin-3 in nasal polyps group and sinusitis group were both significantly positively correlated with the eosinophil counts in the blood (P < 0.05).@*CONCLUSION@#Eotaxin-3 may be involved,in the pathogenesis of chronic rhinosinusitis with and without nasal polyps, and further research will help us to understand the pathophysiology of chronic rhinosinusitis with and without nasal polyps.
