| Objective: To explore the long-term oxygen therapy on bronchial wall thickness and lung function of chronic obstructive pulmonary disease. Methods：Forty patients with moderate severe chronic obstructive pulmonary disease were randomly divided into LTOT group and control group.Both groups were given conventional rehabilitation,and LTOT group was given long term oxygen therapy additionally. Pulmonary function test and HRCT scan were assessed.Results:After two years of treatment,the WT and WA% score of control group were increased than that of before(P<0.05). FEV1/FVC score of control group were lower than that of before(P<0.05).Every score of LTOT group were not significantly different from that of before. Conclusion：Long-term oxygen therapy could be effectively ameliorate the airway remodeling of patients with chronic obstructive pulmonary disease and reduce the degradation of lung function. |
