RESUMEN
Objective To evaluate the value of percutaneous hyperthermia-chemotherapy (PHC)under CT guided in treating original and secondary hepatic and pulmonary malignant tumor.Methods Percutaneous hyperthermia and chemotherapy under CT guided was performed for 21 patient with original and secondary hepatic and pulmonary malignant tumor.Chemical drugs against tumors were warmed to 55～60℃ and injected into the tumors.Injected volume was according to:V=4/3 ?(r+0.5 cm) 3.Observation depends upon attenuation changes of CT scanning and biochemical index(AFP)The therapeutic effect was classified into Ⅰ～Ⅴgrade.Results The period of observation was 36 monthes,In 20 cases,survival period was 8～22 monthes,average survival period was 16 monthes.A patient had treated with PHC and transcatheter arterial embolization and was alive for 28 monthes.Total effective rate was 95.2%.Conclusion PHC under CT guidence is an effective method in treating hepatic and pulmonary malignant tumors.especially for unresected tumors.Cooperating transcatheter arterial embolization(TAE)can raise curative effect.
RESUMEN
Objective:Express the recombinant human FGFR1 in order to screen the FGFs.Methods:A cDNA fragment encoding human fibroblast growth factor receptor 1(FGFR1) was isolated by RT PCR from human lung fibroblasts,and then cloned into pCR TM II plasmid and pFastBac1 donor plasmid.Through transposition,recombinant bacmid FGFR1 DNA was formed and was then transfected into Sf9 insect cells to produce recombinant Baculovirus.Sf9 insect cell were infected with recombinant Baculovirus.The harvested culture supernatant was subjected to Western Blot and ELISA analysis.Results:The size of FGFR1 cDNA fragment is 2 100 bp.The MW of expressed recombinant FGFR1 was 78 kD.ELISA showed that human recombinant FGFR1 was expressed on the membrane of insect cell Sf9.Conclusion:The recombinant human FGFR1 can be expressed on the membrane of insect cell Sf9 effectively.
