Abstract： Objective： To observe the effect of acupuncture combined with pulmonary rehabilitation exercise on postoperative recovery in lung cancer patients complicated with mild chronic obstructive pulmonary disease（COPD） with lung-spleen qi deficiency syndrome．Methods：A total of 108 lung cancer patients complicated with mild COPD with lung-spleen qi deficiency syndrome admitted to the Affiliated Hospital of Shandong Second Medical University between June 2023 and October 2024 were divided into the control group and the observation group using the random number table method，with 54 cases in each group．Both groups received aerosol inhalation therapy starting on the day of surgery． The control group received pulmonary rehabilitation exercise， while the observation group received acupuncture combined with pulmonary rehabilitation exercise． Lung function， exercise tolerance were observed on admission day and at one month postoperatively， while inflammatory markers were assessed on admission day and postoperative day five． Incidence of postoperative complications， duration of thoracic drainaga tube placement and hospital stay were compared between the two groups． Results： At one month postoperatively， forced vital capacity （FVC）， forced expiratory volume in one second（FEV1）， and maximum voluntary ventilation（MVV） decreased compared with those on the admission day（P＜0.05），6-minute walk test（6MWT）distance was shortened compared with that on the admission day in both groups（P＜0.05）．The observation group showed higher FVC and FEV1 levels （P＜0.05）and longer 6MWT distance（P＜0.05）than the control group． On postoperative day five， tumor necrosis factor-α（TNF-α）， C-reactive protein（CRP）， interleukin-6（IL-6）， and interleukin-10（IL-10）levels were elevated compared with those on the admission day in both groups（P＜0.05）．The observation group demonstrated lower TNF-α，CRP，and IL-6 levels（P＜0.05）but higher IL-10 levels（P＜0.05）than the control group．The observation group had lower incidences of postoperative pulmonary infection and atelectasis（P＜0.05）， and shorter duration of thoracic drainage tube placement（P＜0.05）．No significant differenceswerefoundinarrhythmiaincidenceorhospitalstay betweenthetwogroups（P＞0.05）．Conclusion：Acupuncture combined with pulmonary rehabilitation exercise enhances postoperative recovery and reduces the incidence of postoperative complications in lung cancer patients with mild COPD with lung-spleen qi deficiency syndrome.
