Brief summary
The purpose of this study is to evaluate the changes of lung function before and after the exercise in patients with chronic obstructive pulmonary disease.The assessment of quality of life is also carried out through questionnaires.
Detailed description
This is a randomized,open-label study to research the changes of lung function before and after exercise in patients with chronic obstructive pulmonary disease .At baseline,lung function test,blood oxygen saturation and pulse are measured before and after 6-min walk test for each subject.Quality of life is assessed through questionnaires including modified Medical Research Council dyspnoea scale(mMRC),St George's Respiratory Questionnaire(SGRQ),Clinical Chronic Obstructive Pulmonary Questionnaire(CCQ) and chronic obstructive pulmonary assessment test(CAT).And then budesonide(160ug) and formoterol(4.5ug) bid will be given to the subjects for 3 months.The subjects will have a follow-up visit with all the examinations mentioned above after 3 months' treatment.
Interventions
DRUGBudesonide and formoterol bid
At baseline,lung function test,blood oxygen saturation and pulse are measured before and after 6-min walk test for each subject.Quality of life is assessed through questionnaires including modified Medical Research Council dyspnoea scale(mMRC),St George's Respiratory Questionnaire(SGRQ),clinical chronic obstructive pulmonary questionnaire(CCQ) and chronic obstructive pulmonary disease assessment test(CAT).And then budesonide(160ug) and formoterol(4.5ug) bid will be given to the subjects for 3 months.The subjects will have a follow-up visit with all the examinations mentioned above after 3 months' treatment.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Changes of forced expired volume in one second(FEV1) after 6-min walk test compared with resting state | At resting state and after 6-min walk test | Forced expired volume in one second(FEV1) is measured by Jaeger MasterScreen Pulmonary Function Test System before and after 6-min walk test. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Changes of inspiratory capacity(IC) after 6-min walk test compared with resting state | At resting state and after 6-min walk test | Inspiratory capacity(IC) is measured by Jaeger MasterScreen Pulmonary Function Test System before and after 6-min walk test. |
| Changes of blood oxygen saturation after 6-min walk test compared with resting state | At resting state and after 6-min walk test | Blood oxygen saturation is measured before and after 6-min walk test. |
| Changes of pulse after 6-min walk test compared with resting state | At resting state and after 6-min walk test | Pulse is measured before and after 6-min walk test. |
| Changes of forced expired volume in one second(FEV1) after 3 months' treatment compared with baseline | Change from baseline to 3 months | At baseline,forced expired volume in one second(FEV1) is measured.After 3 months's treatment of budesonide and formoterol,FEV1 will be measured again. |
| Changes of inspiratory capacity(IC) after 3 months' treatment compared with baseline | Change from baseline to 3 months | At baseline,inspiratory capacity(IC) is measured.After 3 months's treatment of budesonide and formoterol,IC will be measured again. |
| The distance and steps of 6-min walk test | Change from baseline to 3 months | Both the the distance and steps are measured |
| Changes of impulse forced oscillometry parameters after 3 months' treatment compared with baseline | Change from baseline to 3 months | At baseline,impulse forced oscillometry parameters are measured.After 3 months's treatment of budesonide and formoterol,impulse forced oscillometry parameters will be measured again. |
| Changes of modified Medical Research Council dyspnoea scale(mMRC) scores after 3 months' treatment compared with baseline | Change from baseline to 3 months | At baseline,quality of life is assessed by modified Medical Research Council dyspnoea scale(mMRC).After 3 months's treatment of budesonide and formoterol,the mMRC scores will be measured again. |
| Changes of St George's Respiratory Questionnaire(SGRQ) scores after 3 months' treatment compared with baseline | Change from baseline to 3 months | At baseline,quality of life is assessed by St George's Respiratory Questionnaire(SGRQ).After 3 months's treatment of budesonide and formoterol,the SGRQ scores will be measured again. |
| Changes of clinical chronic obstructive pulmonary questionnaire(CCQ) scores after 3 months' treatment compared with baseline | Change from baseline to 3 months | At baseline,quality of life is assessed by clinical chronic obstructive pulmonary disease questionnaire(CCQ).After 3 months's treatment of budesonide and formoterol,the scores will be measured again. |
| Changes of chronic obstructive pulmonary disease assessment test(CAT) scores after 3 months' treatment compared with baseline | Change from baseline to 3 months | At baseline,quality of life is assessed by chronic obstructive pulmonary disease assessment test(CAT).After 3 months's treatment of budesonide and formoterol,the test will be performed again. |
| Changes of diffusion function after 3 months' treatment compared with baseline | Change from baseline to 3 months | At baseline,diffusion function is measured.After 3 months's treatment of budesonide and formoterol,diffusion function will be measured again. |
