Abstract:
Objective To investigate the action mechanism of Qingjin Huatan Decoction on regulating COPD rats with mucus hypersecretion in airway. Methods Fifty 6-8 week old Wistar male rats were randomly divided into healthy group, model group, Qingjin Huatan Decoction group, clarithromycin group, 10 rats in each group. Except for healthy group, all the other groups were used the combination method of injecting LPS and smudging to establish COPD models. The last three groups were fed with normal saline, Qingjin Huatan Decoction, clarithromycin respectively for 30 days. On the 31st day of the experiment, the rats were put to death to take lung tissue. 6 rats from each group were chosen randomly, and the protein expressions of NE, EGFR and MUC5AC mRNA in lung tissue were detected by real-time fluorescent quantitative PCR. Results The expressions of NE, MUC5AC mRNA in lung tissue of COPD rats were higher than the healthy group. Compared with model group, the expressions of NE mRNA and MUC5AC mRNA in Qingjin Huatan Decoction group and clarithromycin group were markedly lower, while the expressions of NE, MUC5AC mRNA in Qingjin Huatan Decoction group were significantly lower than those in clarithromycin group. The expression of EGFR mRNA in Qingjin Huatan Decoction group was lower than that in model group. Conclusion Qingjin Huatan Decoction can inhibit mucus hypersecretion in airway through NE/EGFR/MUC5AC signal transduction pathway.
