Study on the Prevention and Control System of Chronic Airway Diseases

In this study, patients with Chronic Obstructive Pulmonary Diseases (COPD) in stable and acute exacerbation stage were selected as the research objects, and the open, parallel and randomized controlled clinical trial design was adopted. Participants were randomly divided into trial group and control group. The control group was only given routine education, and the experimental group, on the basis of routine education, developed a respiratory rehabilitation training program lasting for 12 weeks according to the individual situation of patients. All participants were interviewed for 6 times (baseline and 4,8,12 weeks, 6 months and 12 months after admission) for a period of 1 year. Acute exacerbation, activity tolerance (6-minute walking test), living environment, clinical symptoms, lung function, airway inflammation water level index and biological samples were collected at each visit. At the same time, according to the diary filled in by the patients, the investigators can obtain the daily stay time indoors and outdoors and the longitude and latitude information of the regular stay fixed place, and geographic information system (GIS) is used to match the nearest environmental monitoring station, obtain the data of air pollutants and meteorological indicators (SO2, NO2, Co, O3, PM10, temperature and humidity, etc.), and estimate the individual exposure level of air pollutants.

First of all, the investigators need to obtain detailed history records, including cardio pulmonary vascular history, related complications, treatment history and other high-risk factors. After careful review, the investigators need to determine whether the patient is suitable to participate in the pulmonary rehabilitation plan. The investigators need to pay special attention to diseases that may affect the patient's performance, including special cardiovascular diseases, skeletal muscle and nervous system.

Functional evaluation: pulmonary function test, exercise cardiopulmonary function evaluation (6-minute walking test), grip strength test, psychological state evaluation ( Generalized Anxiety Disorder 7-item (GAD-7), Patient Health Questionnaire 9-item (phq-9)), nutrition screening and evaluation and others (general examination such as height, weight, BMI, waist and hip circumference, WHR, blood pressure, heart rate and blood biochemical examination; quality of life evaluation; other related individual evaluation Estimation includes smoking and sleep).

1. Acute exacerbation:

   The exercise prescription of "hospitalization + home rehabilitation" was adopted, which mainly combined aerobic endurance training, intermittent strength training and inspiratory muscle training, as follows:

   Aerobic exercise: 4 times / week, 30min / time, fast walking or power cycling Strength training: unarmed or instrument, 4 times / week, 3 groups / time, 10-12 times / group Breath training: ① breath Trainer: once a day, 20-30min a time

   ② Abdominal breathing training: 1-2 times / day, 10min / time
2. Stable patients:

Using the "home-based rehabilitation" exercise prescription, taking home exercise as the main form, using the sports bracelet and special respiratory rehabilitation app software, the home management system integrating home rehabilitation training, detection and feedback is mainly adopted, which is a combination of aerobic endurance training, intermittent strength training and inspiratory muscle training, as follows:

Aerobic exercise: 2-3 times / week, 30min / time, walk quickly Strength training: elastic band, 2-3 times / week, 3 groups / time, 10-12 times / group Breathing training: ① breathing exercise apparatus, 1-2 times / day, 10min / time

② Abdominal breathing training, 1-2 times / day, 10min / time
