Pulmonary Fibrosis

Introduction Pulmonary fibrosis refers to the formation of collagen, elastin and protein saccharides in the lung interstitial tissues. When the fibroblasts are chemically or physically damaged, collagen is secreted to repair the interstitial tissues of the lungs, which in turn causes lung fibers. The result of human body repair after the lungs are injured. Pulmonary fibrosis occurs mostly in the 40-50 age group, and men are more common in women. Dyspnea is the most common symptom of pulmonary fibrosis. In mild pulmonary fibrosis, breathing difficulties occur during periods of intense activity and are 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.

Cause

Lung dry scrotal injury and lung qi deficiency cold is the main aspect of the pathogenesis. Clinically, this is more common in yin deficiency and heat, or because of acute infection, this is a deficiency of heat and lung.

The cold and cold lungs are often caused by internal injuries such as chronic cough, long-term asthma, etc., and the stagnation of phlegm and blood stasis, or the stagnation of yin and yang, lung deficiency and cold, loss of support. 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.

Spirometer for lung biopsy

1. Progressive urgency, dry cough, lung wet voice or snoring.

2.x line inspection

Early in the shape of frosted glass, typical changes in diffuse lines, nodular, cloud-like, reticular shadow, lung volume reduction.

3. Laboratory inspection

It can be seen that ESR and LDH increase, and generally have no special significance.

4. Pulmonary function test

Reduced lung capacity, decreased diffuse function, and hypoxemia.

5. Lung tissue biopsy provides a pathological basis.

Differential diagnosis

There are more than two types of clips in clinical practice. 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, it was more common to have lung yin deficiency, and in the late stage, qi and yang deficiency were more common.

Most of the lungs are caused by the evil of dryness and heat, and the evil of dryness can also burn the blood, and the blood will overflow into the veins, or it can be blood stasis, or the blood can be stagnation and the blood is not smooth. Blood, qi and yin deficiency can also lead to blood stasis, qi deficiency and inability to transport blood, blood stagnant to become blood stasis. Once the blood stasis is formed, it can in turn affect the sway of the air machine. It is difficult to spread the yin and yang, and the lungs are weakened and the lungs are further aggravated. Clinically, patients with pulmonary interstitial fibrosis have blood stasis in symptoms, signs and laboratory tests, such as dull complexion, cyanotic lips, increased blood viscosity, etc., late affecting right heart function leading to right heart dysfunction At the time, there may be obvious signs of blood stasis such as systemic stagnation of blood.

Pulmonary interstitial fibrosis is the final outcome of a variety of lung diseases, and its etiology varies, but its clinical symptoms, imaging and lung function have some similarities, and its pathogenesis and pathological features also have certain Common features. According to the characteristics of the pathogenesis of pulmonary fibrosis, pulmonary fibrosis is based on the differentiation and treatment of traditional Chinese medicine. The method of activating blood circulation to remove blood stasis and relieving collaterals as the fundamental method of pulmonary fibrosis has been treated continuously and has received good clinical results.
