Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
The clinical control rate of sputum
Time Frame: Day 7
Defined as the proportion of patients with the expectoration rate ≥90%.
Day 7

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Time to sputum turn white
Time Frame: up to Day 7
up to Day 7
Cough Symptom Score Scale
Time Frame: 0,Day 3, Day 7
Cough Symptom Score Scale include Day Cough Symptom Score and Night cough symptom score. In Day Cough Symptom Score, zero means no cough,one means occasionally short cough,two means frequent cough, slightly affecting daily activities,three means frequent coughing seriously affects daily activities;In Night cough symptom score,zero means no cough,one means short-term cough when falling asleep or occasional night cough,two means cough slightly affects night sleep,three means cough seriously affects night sleep.
0,Day 3, Day 7
Use of Antibiotic
Time Frame: 0,Day 3, Day 7
0,Day 3, Day 7

Time Frame: 0,Day 3, Day 7
0,Day 3, Day 7
The Phlegm-heat Syndrome (Tan-re Zheng) scale
Time Frame: 0,Day 3, Day 7
The Phlegm-heat Syndrome (Tan-re Zheng) scale include measures of the main symptoms and the secondary symptoms. The main symptom is about the color ，the characteristics and the amount of sputum.Each one includes four levels,0 represents normal，3 represents mild symptom,6 represents moderate symptom,9 represents Severe symptom.The secondary symptoms include Day cough，Night cough，Dry throat thirst，fever，blush，Dry stool，Yellow urine ，Red tongue and pulse.Each one includes different levels.The higher score represents the more meeting The Phlegm-heat Syndrome (Tan-re Zheng) ，the lower score means the opposite.
0,Day 3, Day 7
The change value about the volume of sputum after treatment
Time Frame: 0,Day 3, Day 7
Monitor the sputum volume everyday and compare changes in sputum volume in the treatment.
