中文摘要：

目的：探讨唾液酸Lewis-X（SleX）在慢性鼻-鼻窦炎鼻黏膜组织中的表达。方法：利用SleX单克隆抗体,通过免疫组织化学技术对9例慢性鼻-鼻窦炎患者鼻黏膜组织及7例正常对照鼻黏膜组织进行染色,分析SleX在鼻黏膜组织中的表达。结果：SleX在鼻黏膜上皮细胞及中性粒细胞均有表达。SleX在慢性鼻-鼻窦炎鼻黏膜上皮细胞中的表达阳性率为88.9%,在正常鼻黏膜上皮细胞中的表达阳性率为14.3%,差异有统计学意义（P〈0.05）。结论：SleX在慢性鼻-鼻窦炎黏膜组织高表达,可能参与慢性鼻-鼻窦炎的发生。

英文摘要：

Objective：To explore the expression of SleX in nasal epithelium in patients with chronic rhinosinusitis. Method：Nine nasal epitheliums from patients with chronic rhinosinusitis and 7 normal controls were stained with SleX antibody by immunohistochemistry, and its expression were analyzed. Result：Both nasal epithelial cells and neutrophils expressed SleX. Nearly 88. 9% nasal epithelium from patients with chronic rhinosinusitis expressed SleX while 14.3% in normal control. Expression of SleX in nasal epitheliums from patients with chronic rhinosinusitis were higher than that in normal control. There were significant difference between two groups. Conclusion： Nasal epithelium from patients with CRS is highly expressed SleX. It may involve the occurence of chronic rhinosinusitis.
