Abstract: Western medicine clinically mainly uses immune regulation, urinary protein reduction, anti-inflammatory, anti-platelet and blood purification as the main treatment methods, but Western medicine alone has a poor therapeutic effect, and long-term use of drugs has relatively large side effects. In traditional Chinese medicine, wind-heat toxins are the cause of pathogenic factors. The body has heat, viscera deficiency, damp-heat content, spleen and kidney deficiency, blood stasis blocking the collaterals; mainly heat, deficiency, blood stasis, wind, dampness, and poison. For pathogenesis, traditional Chinese medicine focuses on promoting blood circulation to remove blood stasis, dispersing wind and heat, cooling blood and removing toxins, and replenishing kidney and cooling blood. Professor Tang Yixin treats from the spleen and treats patients with allergic purpura nephritis with hematuria and edema as the main manifestations of Qi and Yin deficiency. The treatment is based on the method of sweetening the spleen, nourishing yin and distilling water, and adding and reducing the spleen soup. The treatment has also achieved good clinical results.
