We observed 18 cases of chronic bronchitis and 5 cases of pathological morphology. 16 cases of lesion and 4 cases of control, the specimen was not preserved because of the general, only from the original wax block was re-sliced for observation. There were two specimens of large specimens and one control group. All the specimens were taken from the bronchus of the upper and lower lobe of the right lung, and the paraffin embedded sections were observed.

Bronchial mucosal epithelial cells at all levels showed hyperplasia, regeneration and squamous metaplasia and other changes, of which the more squamous metaplasia
