Description

Traditional Chinese medicine composition for treating interstitial lung disease and application thereof

Technical Field

The invention relates to a traditional Chinese medicine composition and application thereof, in particular to a traditional Chinese medicine composition for treating interstitial lung diseases and application thereof.

Background

Interstitial Lung Disease (ILD) belongs to the category of consumptive lung Disease in traditional Chinese medicine, and has the main clinical manifestations of cough, chest distress and dyspnea. Traditional Chinese medicine considers that ILD is a disease which takes the lung and spleen as the core to take the dysfunction of viscera and the overall decline of the body function state as basic pathological changes. The lung lobes of ILD patients are withered due to consumption of body fluids and dryness of the lung, which is caused by consumption of body fluids and qi, and the lung lobes are dry when dry, but weak when not used. The abundance of lung qi depends on the distribution of spleen qi, while the deficiency of spleen qi leads to the deficiency of lung qi. The root of qi is in the kidney, kidney deficiency makes it impossible to take the food, qi fails to return to original, and yang, qi, yin and body fluids are easy to dissipate. The disease is manifested in the lung, but its pathological changes are closely related to the spleen, stomach and kidney. The lung governs qi and the spleen is the source of qi and blood. The spleen and stomach transporting and transforming food essence can nourish lung qi, the spleen qi is weak, and the transportation and transformation cannot be performed, which results in lung qi deficiency and qi failing to transform body fluids, resulting in lung malnutrition and lung atrophy and atrophy.

The pathogenesis essence of interstitial lung diseases is deficient, excessive, cold and heat mixed, and the syndrome characteristics are mainly the deficiency of both lung and spleen, and relate to the function deficiency of a plurality of internal organs, so that the interstitial lung diseases can be essentially treated only by carrying out the integral differentiation of the internal organs with the lung and the spleen as the core and applying the treatment principle of 'warm-moistening and pungent-gold banking up root'.

2. Results of the experiment

2.1 general State description of rats

A total of 5 rats died during the experiment. Among them, 4 model groups and 1 prednisone acetate group were considered to be related to the cytotoxicity of BLM, and the correlation between the cause of death and factors such as the constitution of rats and the tolerance to toxicity was not excluded.

After the dead rats are dissected, the lung congestion and swelling of different degrees are found, and pleural effusion is seen in some cases. The cause of death was considered to be related to bleomycin cytotoxicity.

The rats in the normal group have sensitive reaction, good spirit, stable respiration, strong body, good drinking and eating, bright hair color and gradually increased weight; the rats in the model group showed listlessness, rapid respiration, slow movement, bows, knees, loose fur, lusterless fur, even filthy fasciculation, decreased intake of water, rapid weight loss after model building, and slow body weight increase after two weeks. The rats in each administration group generally have better conditions than those in the model group, the body weight of the rats rapidly decreases after the model is built, and the body weight increases to different degrees after one week.

3 conclusion

Monocyte chemotactic protein 1 (MCP-1) belongs to CC-chemotactic factors, and is secreted by macrophages, endothelial cells, monocytes, dendritic cells, epithelial cells and the like, and inflammatory cells such as monocytes/macrophages, lymphocytes and the like are mainly chemotactic and gathered to a lesion part and activated to generate various cytokines, so that inflammation is generated and developed. In addition, MCP-1 remarkably stimulates lung fibroblasts to synthesize collagen, can cause the production of cytokines or mediators with fibroblast properties, promotes the accumulation of myofibroblasts at the site of lung injury, participates in the formation of pulmonary fibrosis, and is considered to be an important fibrosis-causing chemokine. IL-6 is a multifunctional cytokine with a wide range of biological activities. IL-6 can increase collagen aggregation, inhibit ECM degradation, stimulate fibroblast proliferation, etc. TNF-alpha is a proinflammatory cytokine, is highly expressed in the pathological process of lung injury, participates in local injury and inflammatory reaction, causes inflammatory cell aggregation, further stimulates a large amount of lung fibroblasts to proliferate and secrete collagen, stimulates the release of other cytokines such as IL-1 and the like, and is an important mediator for the generation of lung inflammation. Stimulates the expression of MMP-9 and collagenase and the synthesis of collagen. The research finds that the traditional Chinese medicine composition can reduce the levels of MCP, IL-6 and TNF-alpha in lung tissues, relieve inflammatory reaction and reduce collagen synthesis, thereby playing a role in resisting fibrosis. The experimental result shows that the traditional Chinese medicine composition has better anti-inflammatory and anti-fibrosis action trend than prednisone.

Acute toxicity test results show that the maximum tolerated dose of the traditional Chinese medicine composition is 357.6g (crude drug)/kg after gastric lavage of ICR mice, which is equivalent to 3.6 times of the clinically planned dose, and no abnormality is found.
