HE staining and SEM assay on the histological changes in the early stage after tracheostomy (a): HE staining analysis on trachea structure changes within a week after tracheostomy. b SEM analysis on the changes of cilia and mucosa in the early stage after tracheostomy. c The changes on the white blood cell counts in HE staining (**p < 0.01 and ***p < 0.001 vs. Normal). d The changes on the damage area of cilia and mucosa in the SEM a (***p < 0.001 vs. Normal)
