Toll样受体-2和血红素加氧酶-1在复发性鼻息肉中的表达及意义

目的：研究复发性鼻息肉组织中TLR-2、HO-1的表达和意义，并探讨2者表达与鼻息肉复发的关系．方法采用免疫蛋白印记技术，检测复发性鼻息肉组20例组织、鼻息肉组20例组织及正常对照组20例钩突粘膜组织中TLR-2、HO-1蛋白表达情况，并比较分析2者之间的关系．结果复发性鼻息肉组织中TLR-2、HO-1的表达量与鼻息肉组织相比差异有统计学意义（P〈0.05）；鼻息肉组织中TLR-2、HO-1的表达量与正常鼻黏膜组织相比差异有统计学意义（P〈0.05）；TLR-2和HO-1在各组的表达量存在明显的相关性（P〈0.05）．结论 TLR-2、HO-1在鼻息肉复发机制中发挥着重要作用，2者可能作为鼻息肉患者术后随诊和复发趋势判断的客观指标．

Expression and Significance of Toll-like receptor-2 and Heme oxygenase-1 in Recurrent Nasal Polyps

Objective To investigate the expression and significance of TLR-2 and HO-1 in recurrent nasal polyps,and to discuss the relationship between the expression and the recurrence of nasal polyps. Methods The immune protein imprinting technology was used to detect the protein expression of TLR-2 and HO-1 in 20 cases of recurrent nasal polyps,20 cases of nasal polyps and 20 cases of normal mucosal tissue in control group, and the relationship between the two proteins were analyzed. Results Expression levels of TLR-2 and HO-1 in the tissues of the recurrent nasal polyps had statistically significant difference with nasal polyps group （ P〈0.05） . Expression levels of TLR-2 and HO-1 in the tissues of the nasal polyps had statistically significant difference with normal nasal mucosa tissues （ P〈0.05） .The expression of TLR-2 and HO-1 had significant correlation in each group （ P〈0.05） .Conclusion TLR-2 and HO-1 plays an important role in the recurrence mechanism of nasal polyps, and both of them may be as objective indicators for postoperative follow-up of patients with recurrent nasal polyps and judging the recurrent trend.
