Abstract:Objective To observe the effects of Xuanfei Jianpi Formula on the lung tissue pathology, airway goblet cells and Mucin5AC (MUC5AC) in rats with chronic obstructive pulmonary disease (COPD). Methods Forty Wistar male rats aged 10 to 12 weeks and weighing (230±20) g were divided into blank group, model group, traditional Chinese medicine group, and western medicine group according to random number table method, with ten rats in each group. Except the normal feeding of the blank group, the other groups were treated with lipopolysaccharide injection and smoked cigarettes to prepare COPD rat models. After the modeling, the traditional Chinese medicine group was given Xuanfei Jianpi Formula (1 ml/ 100 g), the western medicine group was given Mucosolvan (1 ml/100 g), and the blank and the model groups were given 0.9% normal saline for 14 consecutive days. Hematoxylin and eosin (HE) staining was performed to observe lung tissue pathology, and the total number and classification of white blood cells in bronchoalveolar lavage fluid (BALF) were detected. Goblet cells were observed by Alcian blue periodic acid-Schiff (AB-PAS) staining, and MUC5AC was detected by immunohistochemistry. Results The lung structure of blank group was complete, no inflammatory cell infiltration was observed, the lung structure destruction and inflammatory reaction were obvious in the model group, and the lung structure and inflammatory reaction were improved in the traditional Chinese medicine group compared with the model group. The total number of white blood cells, neutrophils and lymphocytes in BALF in model group were higher than those in blank group, and the differences were statistically significant (P<0.05). The total number of white blood cells, neutrophils and lymphocytes in BALF in traditional Chinese medicine group were lower than those in model group, and the differences were statistically significant (P<0.05). There were a few goblet cells occasionally in blank group, and the goblet cell proliferation in model group was higher than that in blank group. The goblet cell proliferation in the traditional Chinese medicine group and the western medicine group was lower than that in model group. The relative coloring area of model group was higher than that of the blank group, and the difference was statistically significant (P<0.05). The relative coloring area of the traditional Chinese medicine group was lower than that of model group, and the difference was statistically significant (P<0.05). The expression of MUC5AC protein in lung tissue of model group was higher than that of the blank group, and the difference was statistically significant (P<0.05). The protein expression of MUC5AC in the traditional Chinese medicine group group was lower than that in the model group, and the difference was statistically significant (P<0.05). Conclusion Xuanfei Jianpi Formula may down-regulate the expression of MUC5AC and reduce airway mucus hypersecretion by inhibiting goblet cell metaplasia. At the same time, it can reduce the pathological damage of lung tissue.
