Interstitial pneumonia is a newly prevalent disease, which is not only the name of western medicine, but also a saying of western medicine. many patients and their families and relatives are easy to understand as a disease. In fact, it can be divided into four types: common interstitial pneumonia (UIP), exfoliative interstitial pneumonia (DIP), acute interstitial pneumonia (AIP) and non-specific interstitial pneumonia (NSIP). Most interstitial pneumonia is a prelude to pulmonary fibrosis.

Common interstitial pneumonia (UIP), which has increased by 87% in the last 10 years or so, is easy to form more than 200 diseases, which can be said to be a combination of diseases. On the whole, it is a group of diseases with various causes and manifestations, but all of them mainly damage the respiratory membrane, such as thickening, degeneration, gas diffusion dysfunction and so on. However, the lesions were uneven, including interstitial inflammation, pulmonary fibrosis and honeycomb-like changes.

Exfoliative interstitial pneumonia (DIP) can be said to be respiratory bronchiolar interstitial pneumonia (RBILD). Pathologically, a large number of macrophages were evenly distributed in the alveolar cavity, especially in the air cavity around the bronchiols. nonspecific interstitial pneumonia (NSIP) was characterized by inflammation of the alveolar wall, infiltration of plasma cells and lymphocytes, and the tendency of pulmonary fibrosis, and obvious lesions occurred around the bronchioles.

Acute interstitial pneumonia (AIP) is a rapidly developing explosive lung injury, showing alveolar epithelial damage, type II epithelial tissue hyperplasia, alveolar septum edema, intraalveolar hemorrhage and hyaline membrane formation, which is very similar to acute respiratory distress syndrome (ARDS). There was no gender difference in acute interstitial pneumonia, the case fatality rate was more than 60%, and the life expectancy was 1-2 months.
