This single-center, randomized, double-blind, placebo-controlled trial was undertaken at an outpatient clinic in Shuguang Hospital. Newly diagnosed cough variant asthma adult patients with the T.C.M. pattern of pathogenic-wind are randomly divided into treatment and control group, with 60 patients in each group. Clinical observation of the Respiratory Impedance and Inflammation in Cough Variant Asthma adults reated in Combination of Chanqin Granules.
This single-center, randomized, double-blind, placebo-controlled trial was undertaken at an outpatient clinic in Shuguang Hospital. Newly diagnosed cough variant asthma adult patients with the T.C.M. pattern of pathogenic-wind are randomly divided into treatment and control group, with 60 patients in each group. All patients enrolled are treated with Budesonide + Formoterol Fumarate dry power (160/4.5ug bid) for inhalation. The treatment group are given additional Chanqin granulate (10g bid) and placebo granulate for controlled group. Investigators hypothesis that Chanqin granules may reduce day \& night cough score as well as the respiratory impedance, inflammation statues, and improve T.C.M. syndrome after 8 weeks of treatment.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.
Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.
Chronic obstructive pulmonary disease: long-term lung disease that makes it hard to breathe out, including emphysema and chronic bronchitis.

patients are treated with Budesonide + Formoterol Fumarate dry powder (160/4.5ug bid) for inhalation and additional Chanqin granules 10g three times a day. All granules will be taken orally with 200 ml warm water.

Impulse Oscillometry
The patients will be seated comfortably in a nonswivel chair. Nose clips were applied and a special mouthpiece will be used. For Impulse Oscillometry measurements (MasterScreen, CareFusion, San Diego, California) are performed according to the protocols of the European Respiratory Society. Patients will be advised to cradle their cheeks with their hands. Patients are allowed to breathe normally while the loudspeaker delivere intermittent multi-frequency impulses over a minimum of a 30-s period. A trained technician will guide and assist the patient during the procedure, which involved three to five sinusoidal readings, depending on the incidence of cough, swallowing, and holding of breath. The recordings with the best coherence at frequencies from 5 to 30 Hz will be chosen. The technician is also trained to capture subclinical leaks through the mouthpiece, and leaky recordings will be discarded. The Impulse Oscillometry parameters measured are Zrs、R5、R20、X5.
Time frame: 2 week
Cough severity
Cough severity is measured by a validated verbal category-descriptive (VCD) scores which patients reported. =The scale has 6 discrete values: 0=no cough; 1=one short period of mild cough without hardship; 2=some short periods of cough without much hardship; 3=frequent coughing that does not affect normal daily life or sleep; 4=serious coughing that is very frequent and interferes with normal daily life or sleep; 5=distressing continuous coughing that did not stop for 24 h.
Time frame: 2 week
Exhaled nitric oxide
Exhaled nitric oxide is measured using a portable analyzer, the NIOX MINO (Aerocrine AB, Solna, Sweden). Participants performe a 10 seconds slow steady exhalation. Three successive recordings at 1-minute intervals, expressed as parts per billion (ppb), are made.
Time frame: 2 week
Plan to share: No — Access to these data and associated recommendations generated under the project will be available for educational, research and non-profit purposes.
