This invention is to manufacture a kit for preparation of nano-targeted liposome drugs in combined chemotherapy and radionuclide therapy. It is a kit consisting of three components: (1) A 10 ml vial A which contains BMEDA, gluconate acetate, SnCl2. (2) A 10 ml vial B which contains DSPC, cholesterol, DSPE-PEG, and Doxorubicin(DXR) (or Daunorubicin, Vinolbine). (3) A 10 ml vial C which contains 188ReO4− (or 186ReO4−) solution. The procedure of using the kit is as follows: (1) Remove the contents of the 188ReO4− (or 186ReO4−) solution from vial C. (2) Inject the 188ReO4− (or 186ReO4−) solution into the vial A, and the mixtures react in appropriate temperature. (3) Remove the contents of the 188Re-BMEDA (or 186Re-BMEDA) solution from vial A. (4) Inject the 188Re-BMEDA (or 186Re-BMEDA) solution into the vial B, and the mixtures react in appropriate temperature. The reconstituted solution in the vial B is applied to combine bimodality radiochemotherapy for treatment of tumor and ascites.

A mammal dedicated cell line is provided, which is a HepG2 hepatocellular carcinoma cell line (HepG2/NF-kB/Luc/sr39tk)1_18 obtained by co-transformation with NF-kB/Luc and NF-kB/sr39tk. Firstly, a successfully transformed pNF-kB/Luc HepG2 cell is obtained. Then, a dedicated cell line sensitive to TPA and MTX is generated by experimental screening Next, a plasmid construct carrying pNF-kB/sr39tk genome is introduced into the dedicated cell line by means of Superfect protocol. Finally, a HepG2 cell line co-expressing NF-kB/Luc and NF-kB/sr39tk is screened with G418 and ZEOCIN, and transformation result is confirmed by luminescence and radio activity. The (HepG2/NF-kB/Luc/sr39tk)1_18 obtained is suitable to screen drug for treating liver cancer and examine these cells by bioluminescence imaging and nuclear medicine imaging.
