目的:通过观测各组慢性哮喘大鼠Notch信号通路相关因子Notch2、Jagged1、HES-1的变化,以及肺组织气道重塑的改善状况,探讨平喘颗粒在哮喘的治疗方面所发挥的作用机制。方法:按随机法将60只大鼠均分至空白组、模型组、地塞米松组、平喘...目的:通过观测各组慢性哮喘大鼠Notch信号通路相关因子Notch2、Jagged1、HES-1的变化,以及肺组织气道重塑的改善状况,探讨平喘颗粒在哮喘的治疗方面所发挥的作用机制。方法:按随机法将60只大鼠均分至空白组、模型组、地塞米松组、平喘颗粒组中。除空白组外,剩余的3组大鼠经卵蛋白+氢氧化铝致敏,复制慢性哮喘大鼠模型,空白组用生理盐水代替致敏液。造模前各组予相应的药物灌胃处理。6周后造模完成,处死大鼠并取其肺组织进行HE染色,在光镜下观察病理变化。使用Real-time PCR法检测Notch2、Jagged1 m RNA,Western blot法检测HES-1蛋白的表达程度。结果:与空白组相比,其余各组肺组织均可观察到明显气道重塑改变,Notch2、Jagged1 m RNA及HES-1蛋白表达明显上升(P<0.05);与模型组相比,平喘颗粒和地塞米松可缓解气道重塑,各因子表达情况显著下降(P<0.05),两组间比较则无明显差异(P>0.05)。结论:Notch2、Jagged1、HES-1表达程度与气道重塑呈正相关,平喘颗粒通过降低Notch2、Jagged1、HES-1表达改善气道重塑,可能是其防治哮喘发生发展的机制。展开更多
