Effect of Compound Sodium Chlorate and Aminophylline Tablets on Chronic Obstructive Pulmonary Disease(COPD).

Study Overview
=================
Brief Summary
-----------------
Acute exacerbation of chronic obstructive pulmonary disease (AECOPD) is an important event in the management of chronic obstructive pulmonary disease. Compound sodium chlolate and aminophylline tablets are one of the most widely used drugs for the treatment of bronchial asthma and chronic bronchitis.

Detailed Description
-----------------
Acute exacerbation of chronic obstructive pulmonary disease (AECOPD) is an unignorable event in the management of chronic obstructive pulmonary disease. It is crucial to seek for effective management strategy. Compound sodium chlolate and aminophylline tablets are one of the most widely used drugs for the treatment of bronchial asthma and chronic bronchitis. Compared with the local bronchodilator recommended by the guidelines, it has the advantages of convenient use and good patient compliance. For the purpose of optimize the management of acute exacerbation of chronic obstructive pulmonary disease and provide more convenient options, we compared the efficacy of combined compound sodium chlolate and aminophylline tablets with nebulized ipratropium bromide inhalation plus systemic glucocorticoids in the treatment of chronic obstructive pulmonary disease ranging from moderate degree to severe degree. We hope this research would benefit patients with chronic obstructive pulmonary, especially those in the grassroots.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| COPD assessment test(CAT) score | Observe the changes in the symptoms of dyspnea each time.The CAT score consists of eight items, each of which has options of 0, 1, 2, 3, 4, and 5. The lower the total score plus the score for the eight items, the lighter the symptoms of COPD.The first item, whether there is cough; the second item, sputum condition; the third item, whether there is chest tightness; the fourth item, when climbing a hill or climbing a layer of stairs, is there any breathlessness;the fifth item, whether chronic obstructive pulmonary disease affects housework; the sixth item, whether it affects going out; the seventh item, sleep situation; the eighth item, whether the energy is sufficient. | The above test was given to the experimental group and the control group on the first, fourth, and eighth days after the treatment. | 
| Potential of Hydrogen(PH),Partial pressure of oxygen(PO2),Partial pressure of carbon dioxide(PCO2) | Arterial blood gas values were monitored, the values measured at each examination were recorded, and changes between each time were observed. | The above test was given to the experimental group and the control group on the first, fourth, and eighth days after the treatment. | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Forced Expiratory Volume in the first second (FEV1)/Forced Vital Capacity(FVC) | Observe the changes in lung function each time. | The above test was given to the test group and the control group on the first and eighth days after the treatment. |
