ABSTRACT Introduction: Chronic obstructive pulmonary disease (COPD) is a respiratory disease characterized by incomplete reversibility of airflow obstruction and persistent respiratory symptoms. Objective: To explore the therapeutic effect of physical exercise on patients with chronic obstructive pulmonary disease in pulmonary rehabilitation. Methods: Forty-eight experimental subjects were divided into control group, experimental group 1, and experimental group 2 for research. The control group received normal medical-related treatment without any other means of intervention. In addition to normal medical-related treatment, experimental group 1 received breathing training and educational interventions and experimental group 2 received exercise, breathing training and educational interventions. Results: The vital capacity of female subjects before and during the experiment ranged from 2.23±0.01 to 2.26±0.04, the FVC ranged from 2.00±0.02 to 2.01±0.03, the FEV1 ranged from 1.03±0.01 to 1.03±0.01,the FEV1% ranged from 55.50±1.29 to 55.25±1.71,the FEV1/FVC ranged from 51.44±0.24 to 50.84±1.00, andthe heart rate ranges from 65.00±0.82 to 65.50±1.29. Conclusions: Exercise training can increase the exercise tolerance of patients with COPD, relieve dyspnea, and improve the quality of life. Level of evidence II; Therapeutic studies - investigation of treatment results.

We aimed to explore the efficacy of bone marrow mesenchymal stem cell (BMSC) transplantation combined with nasal continuous positive airway pressure (nCPAP) for treating severe acute exacerbation of chronic obstructive pulmonary disease (AECOPD). SD rat AECOPD model was established by injecting endotoxin and Staphylococcus aureus and then treated with nCPAP, BMSCs, or nCPAP combined with BMSCs (n = 20) and their conditions were evaluated with BBB score at 1 d, 3 d, 7 d, 14 d, 28 d after treatment along with analysis of apoptosis and BrdU-positive cells as well as NF200 expression by TUNEL kit staining and levels of Th1, Th7 and Th12 before and after treatment. As revealed by BBB score and HE staining, all treatments significantly alleviated the symptom of severe APEOPD (p < 0.05), while compared with nCPAP, the combined treatment exhibited higher efficacy. Besides, upon treatment, apoptosis and level of Th1, Th7 and Th12 was reduced but N200 absorbance value was elevated, with significant difference in combination group (p < 0.05). In conclusion, BMSC transplantation in combination with nCPAP alleviates severe AECOPD by reducing cell apoptosis, repairing cell damage, and regulating T-cell subsets.
