fibrous calcified nodules
Introduction
Introduction Symptoms of calcification of the body's fibrotic nodules occur mostly in the lungs. Pulmonary fibrosis, the name of the disease, that is, the interstitial tissue of the lung is composed of collagen, elastin and protein sugar. When the fibroblast is chemically or physically damaged, collagen is secreted to repair the interstitial tissue of the lung. Causes fibrosis of the lungs; that is, the result of human body repair after the lungs are injured. Clinically, this is more common in patients with insufficient yang, or chronic disease, such as chronic bronchitis and bronchiectasis. It is generally believed that there are many cases of deficiency of heat and lung caused by lung dryness and pain.
Cause
Cause
1. Environmental factors: Inhalation of inorganic dust such as asbestos, coal, organic dust such as mildew dust, cotton dust, as well as toxic gases such as smoke and sulfur dioxide.
2. Repeated infections caused by viruses, bacteria, fungi, parasites, etc., often cause the acute exacerbation of this disease, and it is also a condition for worsening the condition.
3. Drug effects and radiation damage.

Pulmonary examination of lung and pleural auscultation
Pulmonary fibrosis is difficult to occur only during periods of intense activity and is often overlooked or misdiagnosed as other diseases. When pulmonary fibrosis progresses, breathing difficulties occur at rest, and progressive pulmonary dysfunction can occur in patients with severe pulmonary fibrosis. Other symptoms include dry cough and fatigue. 50% of patients have clubbing and cyanosis, and at the bottom of the lungs, they can smell the inspiratory sprint. Although there are difficulty breathing in the early stage, the chest X-ray may be basically normal; in the middle and late stages, there are diffuse reticular or nodular shadows in the lower lungs, occasionally pleural effusion, thickening or calcification.
Diagnosis
Differential diagnosis
Imaging studies can be diagnosed. Clinically, there are more than two types of clips. When the condition is mild, the performance of lung yin deficiency is more. When the condition is heavier, the performance of qi and yang deficiency is more common. In the early stage, the lung yin deficiency is more common, and the late stage is qi and yang deficiency. More common.
Pulmonary fibrosis (PF) is the final outcome of a variety of lung diseases, and its causes are different, but its clinical symptoms, imaging and lung function have some similarities, its pathogenesis, Pathological features also have some common features.
