Abstract:
Objective To investigate the expression of the vascular endothelial growth factor (VEGF) and mucin MUC5AC in nasal mucosa before and after chronic rhinitis - sinusitis and nasal polyps - endoscopic sinus surgery.Methods 75 cases chronic rhinitis - sinusitis and nasal polyps - endoscopic sinus surgery patients were selected as nasal polyps group and 75 cases of nasal bone fracture or epistaxis patients as the control group from January 2012 to January 2015. Took the samples of nasal polyps before surgery and the maxillary sinus mucosa specimens after surgery six weeks of nasal polyps’ patients and on the edge of the inferior turbinate mucosa specimens of the control group to detect eosinophil count by HE staining, and detect the expression of VEGF and mucin MUC5AC by immunohistochemical staining.Results The specimens eosinophils of preoperative nasal polyp group and postoperative nasal polyp group were higher than that of control group (P < 0.05), the nasal eosinophils of postoperative nasal polyp group was lower than that of preoperative nasal polyp group (P < 0.05). The expression of specimens VEGF and mucin MUC5AC area percentages in preoperative nasal polyp group and postoperative nasal polyp group were higher than that in control group (P < 0.05), the expression of nasal VEGF and mucin MUC5AC area percentages in the postoperative nasal polyp group was lower than that of preoperative nasal polyp group (P< 0.05).Conclusion Eosinophil count and the expression levels of VEGF and mucin MUC5AC of nasal mucosa in chronic rhinitis - sinusitis and nasal polyps - endoscopic sinus surgery preoperative are higher, and reduce at postoperative six weeks, VEGF and mucin MUC5AC may be involved nasal repair.
