RESUMO
Lung blood is one of the important concepts of TCM. The functions of lung are regulating qi and body fluid, connecting all vessels, and passing waterway, while the disorders leading to syndrome differentiation of related diseases emphasize lung qi and lung yin, but seldom mention lung blood. In modern studies, Western scholars found that the lungs are closely related to the formation of blood cells, suggesting that pulmonary blood has important clinical significance. Observation found that the pathological function and transformation of TCM and Western medicine involved in pulmonary blood are particularly evident after radiotherapy and chemotherapy. Based on this, this article elaborated the treatment of tumor after radiotherapy and chemotherapy based on pulmonary blood syndrome, and provided new ideas and methods for the treatment of integrated traditional Chinese and Western medicine for tumors.
