Abstract: The invention provides a diagnostic kit for metastasis and invasion of breast cancer and a use of an shRNA molecule for silencing expression of human LINC01614. The shRNAs obtained by the invention can interfere with the expression of LINC01614, thereby reducing the migration and invasion ability of tumor cells, inhibiting the expression of EMT proteins, and inhibiting tumor formation and lung metastasis in an animal model in vivo. The invention provides a new solution for targeted therapy of breast cancer. Therefore, the kit for diagnosing metastasis and invasion of breast cancer and the medication for treating metastasis and invasion of breast cancer are developed. The invention provides a new way and strategy for diagnosing and treating metastasis and invasion of breast cancer.

Abstract: The present disclosure relates to a drug combination for treating non-small cell lung cancer, in particular to uses of ergosterol combined with gefitinib, and belongs to the technical field of biomedicine. In the present disclosure, the mechanism of action that ergosterol (ERG) combined with gefitinib (GEF) induces apoptosis of non-small cell lung cancer (NSCLC) cells is firstly studied; then an RGG cyclic peptide/R8 peptide modified ERG combined with GEF active drug-loaded targeted liposome delivery system (RGD/R8-ERG/GEF-LIP) is constructed; and the RGD/R8-ERG/GEF-LIP is prepared into a freeze-dried powder to improve stability, quality evaluation and preliminary evaluation of in vitro anti-lung cancer effects are conducted, and a nude mouse lung cancer xenograft model is established for conducting preliminary pharmacodynamic research and in vivo targeting research.

Abstract: An arsenic compound solution, and an albumin nanoparticle and a lyophilized preparation prepared using same and entrapping an arsenic compound. The arsenic compound solution is prepared using the following method: adding As2O3 powder in sterile deionized water to obtain a suspension, 6 to 25 mg of As2O3 powder being added in every mL of sterile deionized water; dripping an NaOH solution to the obtained suspension until the powder is fully dissolved and adjusting the pH of the solution to 7.5 to 9, and making the concentration of the obtained arsenic compound solution be 5 to 20 mg/mL in terms of the added As2O3. The albumin nanoparticle is prepared by mixing an albumin solution and the arsenic solution and the arsenic solution with the mass ratio of the added As2O3 in arsenic compound solution to the albumin ranging from 1:5 to 1:20 and using a method of solvent removing and physical curing.
