Results: The mRNA expression of SCGB3A2 and 2A1 was obviously downregulated in the tissues from CRS with or without nasal polyps (NPs) patients compared with control tissues. The effects of the different cytokines on these two members are just opposite in the process of nasal explant culture. The tissues from CRS with NPs express higher levels of SCGB1D4 and 1C1mRNA than tissues from CRS without NPs and controls. The effects of the different cytokines on these two members are also opposite in the process of nasal explant culture. The mRNA expression of SCGB2A2, SCGB 1D1 and SCGB 3A1 was apparently upregulated in the nasal mucosa from CRS patients without NPs compared with CRS with NPs and control tissues. Immunohistochemistry revealed weakened protein expression of SCGB3A2 in epithelial cells and submucosal glands in samples from CRS patients. No association between the UGRP1 -112G/A SNP and CRS, any subgroup of CRS, or CRS severity could be found. Conclusion: Secretoglobin polypeptides may play an important role in the pathogenesis of CRS and correlates with disease severity and response to surgery. Different cytokines can regulate Secretoglobin family expression in nasal mucosa differentially through modulating mRNA. The UGRP1 -112G/A SNP may not exert a substantial influence on the development of CRS in the Chinese Han population. 1 1 中英文缩略词表 英文缩写 CC10 英文名称 Clara cell 10-kDa protein 中文名称 Clara 细胞 10-kDa 蛋白 NP nasal polyps 鼻息肉 CRS PBS chronic rhinosinusitis phosphate buffered saline 慢性鼻-鼻窦炎 磷酸盐缓冲液 IL interleukin 白细胞介素 TNF-α IFN tumor necrosis factor α interferon 肿瘤坏死因子 α 干扰素 RNA ribonucleic acid 核糖核酸 GAPDH Glyceraldehyde 3-phosphate dehydro Genase 三磷酸甘油醛脱氢酶 FCS Fetal calf serum 胎牛血清 PCR Polymerase chain reaction 聚合酶链式反应 RT-PCR OD reverse-transcription PCR optical density 逆转录 PCR 光密度 DEPC diethyl p
