A model figure about the treatment of QBPF on COPD: we supposed that there is immune imbalance and microecological disorder in COPD. QBPF may up-regulate Lactobacillus and down-regulate Bacteroides, Prevotella_9 and other intestinal and pulmonary microbiota, regulate the level of Th17/Treg cells and the expression of related cytokines and transcription factors, so as to regulate immune homeostasis, ameliorate pulmonary inflammation and achieve the therapeutic effect on COPD
