Ciliated epithelial cells are damaged and shed

Introduction The bronchus causes chronic inflammation due to various reasons, causing degeneration of the epithelial cells, necrosis and shedding, and the pseudostratified ciliated columnar epithelium is replaced by squamous cell hyperplasia. Respiratory muscle exercise can make the respiratory muscles, especially the diaphragm muscles strong and strong, improve the breathing efficiency, promote the discharge of sputum, can mobilize the vital system of the immune system, reduce the repeated infection of the bronchus, lungs and acute inflammation. Patients can usually exercise controlled deep breathing exercise, abdominal breathing exercise, lip exhalation and other exercises.

Cause

Chronic inflammation of the bronchi.

Differential diagnosis

The symptoms of ciliated epithelial cell damage and shedding need to be distinguished from the following symptoms.

(a) tuberculosis

Active tuberculosis is often accompanied by symptoms such as low fever, fatigue, night sweats, and hemoptysis; the degree of cough and sputum is related to the activity of tuberculosis. X-ray examination can find lung lesions, sputum tuberculosis test positive, senile pulmonary tuberculosis toxicity symptoms are not obvious, often due to the cover of chronic bronchitis symptoms, long-term undiscovered, should pay special attention.

(two) bronchial asthma

The onset age is mild, often with a history of individual or family allergic disease; tracheal and bronchial responsiveness to various stimuli, manifested as extensive bronchospasm and stenosis, clinically have paroxysmal dyspnea and cough, onset Short or continuous. Chest percussion has been unvoiced, and auscultation has a wheezing sound with prolonged exhalation and high pitch. Chronic bronchitis often occurs in the late stage. Roar eosinophils are more common in patients with bronchial asthma, while those in patients with asthmatic bronchitis have fewer sputum.

(three) bronchiectasis

Occurred in children or adolescents, often secondary to measles, pneumonia or whooping cough, repeated recurrent seizures and hemoptysis. Wet rales can be heard in the lower part of both lungs. Chest X-ray examination showed deeper bronchial shadows in the lower lungs. Bronchial iodine oil angiography showed columnar or cystic bronchiectasis.

(4) Heart disease

Cough caused by stagnation of the lungs, often dry cough, not much. Detailed medical history can be found in heart disease, shortness of breath, lower extremity edema and other signs of heart disease. Signs, X-rays, and electrocardiograms are helpful for identification.

(5) Lung cancer

Most occur in men over the age of 40, long-term smokers, often with blood in the sputum, irritating cough. Chest X-ray examination of the lungs with block shadows or obstructive pneumonia. exfoliated cells or fiberoptic bronchoscopy can confirm the diagnosis. The sputum examination and bronchoscopy can be diagnosed.
