Abstract:
Objective Streptococcus pneumoniae is one of the main pathogenic factors of chronic rhinosinusitis (CRS). This study was to explore the method of establishing a CRS model in C57BL/6J mice.Methods Thirty C57BL/6J mice were equally randomized into a CRS model, a sham operation and a blank control group. The CRS model was made by implanting type-Ⅲ streptococcus pneumoniae in the maxillary sinuses, the mice of the sham operation group underwent opening and suturing of the maxillary sinuses without implantation of any streptococcus pneumonia, while the blank controls did not receive any operation. Two months later, all the mice were sacrificed and the nasal sinus mucosal tissue was harvested, embedded with paraffin, sectioned, and subjected to HE staining, followed by observation of the pathological changes under the microscope.Results The CRS model mice exhibited significant proliferation and disorderly arrangement of epithelial cells in the nasal mucosal tissue, with degeneration, necrosis, exfoliation, ulceration, goblet cell proliferation, gland and tissue hyperplasia, and infiltration of lymphocytes, plasmocytes and monocytes. No obvious inflammation was observed in the sham operation and blank control groups. The pathology index score of the nasal sinus mucosal tissue was significantly higher in the CRS model than in the sham operation and blank control groups (\[14.800±5.200\] vs \[2.000±2.906\] and \[1.800±2.098\], P<0.05) but no statistically significant difference between the latter two groups (P>0.05).Conclusion The CRS model was successfully established in mice, which has provided some reference for the construction of the CRS model in animals.
