Design outcomes

Primary

MeasureTime frame
The difference between the two groups in the change from baseline in BCSS(Breathlessness, Cough, and Sputum Scale ) score at 7 days ±1 day after medication;For subjects with positive sputum culture, the negative conversion rate upon retesting at 7 days ±1 day after medication;

Secondary

MeasureTime frame
Fever resolution rate at 7 days ±1 day after medication;Change from baseline in BCSS (Breathlessness, Cough, and Sputum Scale )score at 14 days ±1 day after medication in subjects with resolved fever;Change from baseline in pulmonary function indicators (FEV1, FVC, IC, RV, RV/TLC, etc.) before and after treatment;Change from baseline in TCM syndrome scores during treatment;Time to fever resolution and fever resolution rate during treatment;Change from baseline in CAT (Chronic obstructive pulmonary disease Assessment Teast)score during treatment;Negative conversion rate of influenza virus nucleic acid detection at 7 days ±1 day after medication;Negative conversion rate of influenza virus nucleic acid detection at 14 days ±1 day after medication;
