Overview of TCM etiology,pathogenesis and syndrome differentiation of pulmonary nodules
Lung cancer is a major chronic disease with the highest incidence and mortality in China,and its early screening is the key to improve the survival and prognosis of lung cancer.Pulmonary nodules are currently considered to be the main signs of early lung cancer and prelung cancer.With the progress of imaging equipment and technology and the improvement of people's health awareness,ordinary chest radiographs can no longer meet doctors'demand for small changes in the lungs during screening for early lung cancer.Especially after the novel coronavirus epidemic,more and more people pay attention to lung diseases,and the detection rate of pulmonary nodules is increasing,which attracts people's great attention.Modern medicine usually adopts regular review as the main man-agement method for early pulmonary nodules,which is trapped in the situation of"easy detection but difficult treatment".As the cultural treasure of our country,the core of TCM theory lies in syndrome differentiation and treatment,but most patients with pulmonary nodules have no relevant symptoms in clinical practice,which makes the treatment of TCM fall into an awkward situation of"no identification".By searching the literature related to TCM diagnosis and treatment of pulmonary nodules in the recent 5 years in the journal database,it is found that TCM has certain advantages in the early prevention and treatment of pulmonary nodules and the suppression of their malignant progression.According to different doctors'ideas and methods of distinguishing and treating pulmonary nodules,this paper summarizes the etiology and pathogenesis of pulmonary nodules characterized by invasion of external pathogens,stagnation of liver Qi(气)and damp-ness of phlegm and blood stasis,as well as the syndrome differentiation ideas from the perspectives of constitution,microscopic,integrated Chinese and Western medicine,lung collars,etc.,with a view to carrying out TCM control and intervention during the"window period"or before and after invasive operation recommended by Western medicine by combining the concept of"preventive treatment"of traditional Chinese medicine,giving full play to the characteristics and advantages of traditional Chinese medicine,providing clinical ideas for the early treatment of lung cancer,and killing the tumor in the cradle.
