The findings demonstrated that QKPC in conjunction with conventional treatment considerably improved clinical outcomes, including overall response rate, FEV\u2081%, and FVC, as compared to conventional Western medicine alone. Additionally, it decreased the inflammatory factor (CRP). QKPC significantly improved the CAT score, mMRC score, 6MWT distance, and PaO\u2082 for AECOPD-specific outcomes (all\n                      <jats:italic>p<\/jats:italic>\n                      \u202f&amp;lt;\u202f0.05).
