Abstract :
Allergic asthma is a complex and chronic inflammatory airway disease. The thymic stromal lymphopoietin (TSLP) signaling pathway plays an important role in asthma. Xiaoqinglong Decoction (XQL) is the first choice to treat cold asthma in clinical settings. In this study, the role of the TSLP pathway in the onset of asthma and the protective mechanism of XQL were investigated. A total of 50 female mice were randomly divided into the following groups: the blank group (A), the model group (B), the XQL group (C), the dexamethasone group (D), and the XQL + dexamethasone group (E). Asthma was induced with ovalbumin, and corresponding drug intervention was carried out for 7 days, after which serum and lung tissue end points were analyzed. Serum interleukin 1β (IL-1β), tumor necrosis factor-α (TNF-α), nuclear factor κB (NF-κB), and TSLP levels were higher in group B than in group A (p 0.05). However these levels were lower in group C and D than in group B (p 0.05), and there was no significant difference between groups C and D (p 0.05). Interestingly, these end points were significantly lower in group E than in groups C and D (p 0.05). Regarding pathologic changes, the inflammatory infiltrate in the lungs of groups C, D, and E was lower than that of group B, especially in group E. We conclude that the TSLP pathway plays an important role in the course of asthma, and can be used as an important target for asthma treatment; XQL may play a role in reducing inflammation and relieving asthma by regulating the TSLP signaling pathway.
