The invention relates to the technical field of application of
glehnia littoralis, in particular to application of
glehnia littoralis in preparation of drugs, and discloses new application of
glehnia littoralis in preparation of drugs for preventing postoperative recurrence and
metastasis of tumors, and the glehnia littoralis is applied to preparation of drugs for preventing postoperative recurrence and
metastasis of tumors under the concentration of not causing
cytotoxicity and toxic and side effects. Through multiple key steps of intervening tumor
metastasis, including inhibition of adhesion of circulating
tumor cells on vascular endothelial cells, inhibition of EMT transformation of the circulating
tumor cells, inhibition of trans-endothelial migration of the circulating
tumor cells and the like, the effect of preventing tumor metastasis or treating tumors is achieved, and meanwhile, the activity of immune cells is improved; the
traditional Chinese medicine composition has the advantages of being capable of enhancing the killing ability of immune cells to circulating tumor cells, prolonging the lifetime, having extremely high safety, and solving the problems that the
immune system and the
rehabilitation ability are damaged in anti-
cancer treatment by traditional medicines, the traditional
cancer prevention and
treatment strategy is limited and the like.
