Abstract:
Autophagy， a mechanism of cell self-protection and self-renewal， is associated with the occurrence and development of lung cancer. Favorable autophagy can slow down the progression of lung cancer， while unfavorable autophagy can promote the progression. Therefore， regulating the level of autophagy is of great significance in the treatment of lung cancer. Healthy Qi deficiency and pathogenic Qi stagnation is an extension of the theory of deficiency and Qi stagnation proposed by the Academician WANG Yongyan. It refers to the pathological process that the abnormal body fluid metabolism caused by Qi deficiency of lung， spleen， and kidney results in phlegm and blood stasis. Lung cancer has the root cause of Qi deficiency of lung， spleen， and kidney and the syndrome of phlegm and blood stasis. The autophagy in lung cancer is interconnected with healthy Qi deficiency and pathogenic Qi stagnation. The Qi deficiency of lung， spleen， and kidney is the key factor for the weakening of favorable autophagy in lung cancer， which inhibits the apoptosis of tumor cells and leads to the accumulation of harmful substances. Phlegm and blood stasis is a direct factor enhancing the unfavorable autophagy in lung cancer， which promotes the autophagic death of normal cells， weakens the immunosuppressive effect of immune cells on tumor cells， and leads to the proliferation and migration of tumor cells. The combination of healthy Qi deficiency and pathogenic Qi stagnation results in the development of autophagy in an unfavorable direction and finally leads to the continuous progression of lung cancer. Therefore， the traditional Chinese medicine （TCM） treatment of lung cancer should follow the principle of reinforcing healthy Qi and expelling pathogenic Qi， removing phlegm and resolving stasis， so as to enhance favorable autophagy while inhibiting unfavorable autophagy. Such therapy can inhibit the proliferation and migration of tumor cells and promote the remission of lung cancer. According to the existing literature， Chinese medicine monomers are mainly used to treat lung cancer by regulating autophagy. The Chinese medicine intervention of autophagy in lung cancer mainly aims to promote the activation of autophagy. This may be because the favorable autophagy weakening caused by the Qi deficiency of lung， spleen， and kidney is the fundamental reason for the development of lung cancer.
