Overview
Brief Summary
The goal of this observational study is to test the Evaluation of the efficacy and mechanism of action about Huang-long Zhi-xiao Granule to improve the control rate of Asthma chronic duration. The main questions it aims to answer are:
- [Relying on the top-level experimental design, scientifically evaluated the efficacy and safety of Huang-long Zhi-xiao Granule in patients with chronic asthma (hot asthma), and provided evidence support for the clinical application of Classical Prescriptions.]
- [Through the retained sample to test Asthma-related inflammatory indicators, immunoglobulins, T cell subsets, etc. To investigate the mechanism of action of Huang-long Zhi-xiao Granule in patients with chronic duration of asthma (hot asthma).]
Detailed Description
Bronchial asthma attacks are erratic and difficult to heal, which seriously affects the quality of life of patients, and their physical and mental health is also seriously affected by asthma. This study will conduct clinical observations in patients with chronic persistence (hot wheezing) of bronchial asthma, scientifically evaluate the efficacy and safety of Huanglong Anti-Wheezing in patients with asthma chronic duration (hot wheezing), and provide evidence support for the clinical application of Huanglong Anti-Wheezing Formula.

Outcomes
Primary Outcomes
Asthma control tests（CAT）
Time Frame: Change from baseline CAT scores at week 4, 8, 21, 34，47 and 52.
CAT will be used to evaluate quality of life. A total score of 0-40 will be given with a higher score indicating a worse condition.
Frequencies of acute attacks
Time Frame: Up to week 52.
It will be assessed by frequencies of asthma-related hospitalizations.The patient's disease progression was recorded by recording the number of acute attacks at each time point, as well as the specific condition at the time of the attack.
Secondary Outcomes
- The dose used by glucocorticoids(Week0(before treatment),week4、week8、week21、week34、week47 and week52.)
- Pulmonary function(Week0(before treatment),week4、week8、week21、week34、week47and week52.)

- Asthma exacerbation severity and hospitalization rate(Week0(before treatment),week4、week8、week21、week34、week47and week52.)
- Score for clinical signs and symptoms(Week0(before treatment),week8 and after follow-up（week52）)
- Rapid-acting beta2 agonists use drugs and doses(Week0(before treatment),week8 and after follow-up（week52）)
