Description for medicine or protocol of treatment in detail:

纳入标准:

哮喘组:纳入符合GINA2017诊断标准稳定期哮喘的患者; 1. 有明确反复发作的喘息、气促、胸闷和咳嗽等症状,与接触冷空气、理化刺激、上呼吸道感染、运动等有关,强度随时间变化,可经平喘药物治疗后缓解或自行缓解。 2. 有明确的气流受限可逆性:支气管舒张试验阳性(吸入支气管舒张药物后,FEVl.0改善大于200ml且大于12%); 3. 有固定性气流受限的确诊哮喘患者也纳入哮喘组中(FEV1.0/FVC<0.7)。 慢阻肺组:纳入符合GOLD2013诊断标准的稳定期慢阻肺患者。 1. 支气管舒张试验后FEV1.0/FVC<0.7; 2. 吸烟史大于10包年或有明确的有害烟雾接触史; 3. 慢性咳嗽、咳痰、憋喘等呼吸系统症状; 4. 排除既往哮喘患者或者有反复发作性喘息患者。 正常对照组:纳入健康非吸烟者。 1. 无吸烟史; 2. 无慢性或严重呼吸系统疾病史,无呼吸系统症状; 3. 肺通气功能检查正常(FEV1.0/FVC>0.7且大于预计值的92%, FEV1.0、FVC均大于预计值的80%,流速容量曲线形态正常); 4. 胸部CT检查无结构性病变,无长径超过lcm的肺结节或肿块。

Inclusion criteria

Asthma group: Patients with stable asthma according to gina2017 diagnostic criteria were included; 1. The symptoms such as wheezing, shortness of breath, chest tightness, cough and other symptoms recur clearly, which are related to exposure to cold air, physical and chemical stimulation, upper respiratory tract infection and exercise. The intensity changes with time, and can be relieved by antiasthmatic drugs or by itself. 2. Definite reversibility of airflow restriction: positive bronchodilation test (fevl. 0 improved more than 200 ml and more than 12%) after inhalation of bronchodilator drugs; 3. Asthma patients with fixed airflow limitation were also included in the asthma group (FEV1.0 / FVC < 0.7). COPD group: stable COPD patients meeting gold 2013 diagnostic criteria were included. 1. FEV1.0 / FVC < 0.7 after bronchodilation test; 2. Smoking history is more than 10 pack years or have a clear history of harmful smoke exposure; 3. Chronic cough, expectoration, asthma and other respiratory symptoms; 4. Patients with previous asthma or recurrent wheezing were excluded. Normal control group: healthy non-smokers were included. 1. No smoking history; 2. No history of chronic or severe respiratory diseases, no respiratory symptoms; 3. The pulmonary ventilation function was normal (FEV1.0 / FVC > 0.7 and greater than 92% of the predicted value; FEV1.0 and FVC were greater than 80% of the predicted value, and the shape of flow volume curve was normal; 4. Chest CT examination showed no structural lesions, no pulmonary nodules or masses larger than LCM.

排除标准:

1. 6周内发生过急性加重的患者; 2. 胸部CT显示肺部肿块直径大于3cm; 3. 其他严重呼吸系统疾病:如广泛的支气管扩张,间质性肺疾病,肺癌,感染性肺疾病,大量胸腔积液等; 4. 有胸部外伤或者手术病史者; 5. 合并其他系统严重疾病:心力衰竭,严重肝肾功能障碍,重度贫血,精神障碍等。 6. 不能配合病史采集、肺功能或胸部CT检查者。

Exclusion criteria:

1. Patients with acute exacerbation within 6 weeks; 2. Chest CT showed that the diameter of lung mass was larger than 3cm; 3. Patients with other severe respiratory diseases, such as extensive bronchiectasis, interstitial lung disease, lung cancer, infectious lung disease, massive pleural effusion, etc; 4. Patients with history of chest trauma or surgery; 5. Patients with other serious diseases: heart failure, severe liver and kidney dysfunction, severe anemia, mental disorders, etc. 6. Patients who cannot cooperate with history collection, pulmonary function or chest CT examination.
