补虚平喘膏对COPD急性加重影响：肺肠同治策略的临床验证

Patients in both groups were followed up for six months after the end of treatment, and it was found that there was no significant difference in the frequency distribution of acute exacerbations of COPD between the two groups (P > 0.05). This suggests that within the follow-up period of this study, the combination therapy with Bu Xu Ping Chuan膏 (a herbal plaster for tonifying deficiency and relieving dyspnea) did not significantly reduce the number of acute exacerbations. The reasons for this may be related to the relatively short follow-up period, limited sample size, and the complexity of factors that trigger acute exacerbations. The long-term impact of Bu Xu Ping Chuan膏 on prognosis may require a longer intervention and follow-up period to become apparent. Future studies could further assess this by increasing the sample size and extending the follow-up duration. In summary, patients with stable chronic obstructive pulmonary disease (COPD) often suffer from airflow limitation, recurrent cough, and other symptoms, which can lead to decreased appetite and gastrointestinal dysfunction such as constipation. Gastrointestinal dysfunction can cause malabsorption of nutrients, further exacerbating deficiencies in the lungs, spleen, and kidneys, thus forming a vicious cycle of the condition. Bu Xu Ping Chuan膏 improves lung function by regulating both lung and intestinal functions, enhancing gas exchange in the lungs, and promoting nutrient absorption in the intestines. This provides the body with sufficient qi, blood, and body fluids, nourishing the lungs and spleen, thereby significantly alleviating symptoms such as fatigue and poor appetite, and improving quality of life. This approach embodies the clinical application of the "lung-intestine co-treatment" strategy.
