Inclusion criteria

✓. Patient is older than 40 years old.
✓. There are characteristics of bronchial asthma and COPD.
✓. There is a history of exposure to risk factors.
✓. Existence of persistent airflow limitation: After the application of bronchodilators, FEV1/FVC\<0.7, and lung function proved reversible exhalation.
✓. The existence of reversible airflow limitation: Bronchial Dilation Test positive.
✓.2Asthma: 1)Patient is older than 40 years old. 2)History of reversible respiratory symptoms. 3) non-smokers. 4)lung function:At least one time proved that the airflow limitation: Bronchial Dilation Test positive.
✓. Patient is older than 40 years old.
✓. Complaints about dyspnea, chronic cough or expectoration.

Exclusion criteria

✕.2 At the time doing lung function test, the factors that affect the airflow limitation are not stopped or just stopped with the time interval not long enough to meet the test standard.
✕.3 Using special accompanying medication. For example, patients with drugs such as glucocorticoid.
