Application of dampness-excreting and stasis-removing square-source extracellular vesicle particles in preparation of medicine for preventing or treating pulmonary fibrosis

The invention provides a dampness-excreting and stasis-removing square-source extracellular vesicle particle, a preparation method thereof and an application of the particle in preparation of a medicine for preventing and treating pulmonary fibrosis. The dampness-excreting and stasis-eliminating square-origin extracellular vesicle particle provided by the invention weakens the advanced fibrosis degree by inhibiting the release of early-stage persistent inflammatory factors, and has a good treatment effect on pulmonary fibrosis. The dampness-excreting and stasis-removing square-source extracellular vesicle particles have the advantages of exact curative effect on pulmonary fibrosis resistance, low side effect and wide medical application prospect. 本发明请求保护本发明提供渗湿散结方源性细胞外囊泡颗粒及其制备方法以及在制备防治肺纤维化的药物中的应用。本发明提供的渗湿散结方源性细胞外囊泡颗粒通过抑制早期持续性炎症因子的释放，减弱晚期纤维化程度，对肺纤维化具有良好的治疗效果。渗湿散结方源性细胞外囊泡颗粒抗肺纤维化作用疗效确切、副作用低，有广阔的医疗应用前景。
