摘要
目的探讨慢性鼻-鼻窦炎嗅觉功能障碍的发病机制和胰岛素样生长因子-1R(insulin-like growth factor 1R,IGF-1R)和Ki-67在嗅黏膜中表达的意义。方法取32例慢性鼻-鼻窦炎患者作为失嗅组,11例单纯鼻中隔偏曲行鼻中隔矫正术者作为对照组,应用免疫组织化学技术检测IGF-1R和Ki-67在两组嗅黏膜表达的分布。结果与对照组相比,实验组嗅黏膜Ki-67和IGF-1R表达明显减少(P<0.05)。结论慢性鼻-鼻窦炎嗅黏膜的再生能力明显减弱,与IGF-1R减少有关。
Objective To study the pathogenesis of dysosphresia in patients with chronic sinusitis,and to discuss expressions and significance of IGF-1R and Ki-67 in olfactory mucosa.Methods There were 32 cases of chronic sinusitis in the experimental group,and 11 cases in the control group.IGF-1R and Ki-67 expressions were determined by immunohistochemistry.Tissue sections were observed under an optical microscope.Results Expressions of IGF-1R and Ki-67 in the olfactory epithelium of 32 patients suffering from the dysosmia were lighter than those in the control group(P0.05).Conclusion IGF-1R promoting regeneration in the olfactory epithelium was notably decreased in the ofactory epithelium of chronic sinusitis patient and may lead to ofactory dysfunction.
