Abstract:
:Electroacupuncture (EA) has been documented as a form of therapy for chronic sinusitis (CRS). The present study aimed to assess the effects of EA combined with interleukin‑10 (IL‑10) overexpression on CRS in mice, and to investigate the associated mechanisms. A mouse model of CRS was established by the administration of ovalbumin (OVA), and overexpression of IL‑10 was induced using virus‑encoded IL‑10. The experimental groups were as follows: i) Control group; ii) OVA group; iii) OVA + EA group; iv) OVA + empty vector group; v) OVA + vector + EA group; vi) OVA + IL‑10 group; and vii) OVA + IL‑10 + EA group. Pathological changes and nasal mucus were analyzed using hematoxylin and eosin staining. Interferon‑γ (IFN‑γ) and IL‑10 were detected via reverse‑transcription quantitative PCR and western blot analyses. The pseudostratified epithelium of the mucosa of the nasal sinus was impaired following the induction of CRS. Treatment with EA and/or IL‑10 reversed the injury. Combination treatment with EA and IL‑10 induced synergistic effects. No infiltration of inflammatory cells was observed in the submucosa following EA and IL‑10 treatment. Compared with the control group, the expression of IFN‑γ and IL‑10 in the OVA group was reduced. By contrast, EA or the overexpression of IL‑10 inhibited this reduction. Furthermore, the combined application of EA and IL‑10 had a significantly more potent inhibitory effect on the reduction of IFN‑γ expression, but not IL‑10. Collectively, EA combined with IL‑10 induced specific effects on CRS in mice, likely through the upregulation of IFN‑γ and IL‑10. The current study presented mechanistic implications for the application of EA as an alternative treatment for CRS.
