The saline water was used as a blank control, and 1% hydrochloric acid of methamphetamine Massachusetts was used as the negative control. Compared with normal saline control, the relative percentage of the lasting time of ciliary movement treated with Chinese medicine Xingbi was 94.1%. There was no remarkable pathological change in the tissue slice of nasal mucosa, and no stimulation on nasal mucous membrane was observed. So these data suggest that nasal thermosensible gel of Chinese medicine Xingbi is of high safety. It has no damage to the mucosa of toads and rats and can be used for intranasal administration.展开更多
目的:通过观察醒鼻凝胶滴鼻剂干预变应性鼻炎(AR)豚鼠鼻黏膜成纤维细胞对Fyn-STAT5信号通路的影响,进一步阐明醒鼻凝胶剂治疗AR可能的作用机制。方法:体外分离培养AR豚鼠鼻黏膜成纤维细胞并进行鉴定;将成纤维细胞分为正常组、模型组、T...目的:通过观察醒鼻凝胶滴鼻剂干预变应性鼻炎(AR)豚鼠鼻黏膜成纤维细胞对Fyn-STAT5信号通路的影响,进一步阐明醒鼻凝胶剂治疗AR可能的作用机制。方法:体外分离培养AR豚鼠鼻黏膜成纤维细胞并进行鉴定;将成纤维细胞分为正常组、模型组、TGF-β1组、醒鼻剂组和雷诺考特组,分别检测各组成纤维细胞中Fyn-STAT5信号通路及相关因子的基因和蛋白变化。结果:细胞鉴定结果显示,F3代成纤维细胞波形蛋白表达呈阳性。MTT检测结果提示,经25ng/m L TGF-β1干预24h后,细胞活力增长最明显。Real-time PCR和Western blot检测结果显示,模型组中Fyn m RNA及蛋白和SCF m RNA高表达(P<0.01),IL-10 m RNA和STAT5蛋白呈现低表达(P<0.01);与模型组比较,3个给药组干预12、24h后,Fyn m RNA及蛋白、SCF m RNA的表达均显著降低,IL-10 m RNA、STAT5蛋白显著升高(P<0.01,P<0.05),干预48h后,酸鼻剂组及雷诺考特组IL-10 m RNA仍明显升高(P<0.01)。结论:醒鼻凝胶滴鼻剂可能通过降低Fyn和SCF表达,同时上调STAT5和IL-10,从而抑制Fyn-STAT5信号传导通路,减轻AR成纤维细胞免疫反应。展开更多
