摘要: 目的  观察地塞米松(dexamethasone,DEX)对慢性鼻窦炎伴鼻息肉(chronic sinusitis with nasal polyps, CRSwNP)患者鼻息肉组织趋化因子生成的影响。方法  收集CRSwNP患者鼻息肉组织,制备单细胞悬液,体外分别用10、50和100 μmol/L DEX处理,24 h后检测细胞活性和细胞培养上清中趋化因子的浓度。结果  10、50和100 μmol/L DEX处理组与未处理组相比,活细胞百分比无显著差别;CC趋化因子配体2(CC chemokine ligand,CCL2)、CCL11、CXC趋化因子配体2(CXC chemokine ligand,CXCL2)和CXCL9水平显著降低;CCL20水平显著增高;CCL3、CCL4 、CCL5、CCL17和CXCL5水平没有变化。结论  DEX抑制鼻息肉组织单细胞悬液中多种趋化因子的生成,提示其可能通过此作用抑制炎性细胞的浸润和炎症反应的发生。

Abstract: Objective  To observe the effect of dexamethasone (DEX) on the production of chemokines in nasal polyp tissue of patients with chronic sinusitis with nasal polyps (CRSwNP). Methods  Dispersed nasal polyp cells were prepared from nasal polyp tissues of CRSwNP patients and then the cells were treated with 10, 50 and 100 μmol/L DEX. The cell viability and levels of chemokines in cell culture supernatant were detected 24 h after DEX treatments. Results  Compared to the untreated group, the percentage of viable cells in the 10, 50 and 100  μmol/L DEX-treated groups were unchanged. The levels of CCL2, CCL11, CXCL2 and CXCL9 were significantly lower, CCL20 significantly higher, CCL3,CCL4, CCL5, CCL17 and CXCL5 unchanged.Conclusion  DEX reduced the production of multiple chemokines in dispersed nasal polyp cells of nasal polyp tissue, which may inhibit infiltration of inflammatory cells and occurrence of inflammatory response.

Key words:  chronic sinusitis with nasal polyps, dexamethasone, chemokine
