Methods: Sixty SPF SD male rats were randomly divided into blank group, model group, control group, and low, medium, and high dose groups, with 10 rats in each group. No model was established in the blank group, and the rat model of post-infectious cough was established in the other groups by smoke combined with lipopolysaccharide (LPS) solution nasal drops and capsaicin atomization inhalation. After successful modeling, the control group was given compound methoxyphenamine solution by gavage at 4.78 ml/(kg·d) of body weight, the low, medium and high dose groups were given Qinxia Qingre Qufeng granule solution by gavage at 44.2 ml/(kg·d), 93.6 ml/(kg·d) and 127.8 ml/(kg·d) of body weight, respectively, the blank group and model group were given 0.9% NaCl by gavage at 10 mL/(kg·d) of body weight, once a day for 14 consecutive days, and the blank group did not receive any treatment. The number of coughs within 3 minutes after the last administration was observed in the six groups of rats, the pathological morphological changes of the lung tissues of the six groups of rats were observed by HE staining, the serum SP, NKA, NKB and CGRP levels of the six groups of rats were detected by ELISA, and the SP, NKA, NKB and CGRP protein expressions of the lung tissues of the six groups of rats were detected by immunohistochemistry. Results: Compared with the blank group, the number of coughs in the model group increased significantly 3 minutes after the last administration (P 0.05). Compared with the control group, there were no significant differences in the serum SP, NKA, NKB, and CGRP levels and the protein expression levels of SP, NKA, NKB, and CGRP in lung tissues of the medium- and high-dose groups (P > 0.05), and the serum SP, NKA, NKB, and CGRP levels and the protein expression levels of SP, NKA, NKB, and CGRP in lung tissues of the low-dose group were higher (P < 0.05). Conclusion: Qinxia Qingre Qufeng Granule can reduce the serum SP, NKA, NKB, and CGRP levels of PIC rats, inhibit the protein expression of SP, NKA, NKB, and CGRP in rat lung tissues, and reduce the inflammatory infiltration of lung tissues, thereby reducing airway neurogenic inflammation and promoting disease recovery.展开更多
