RESUMEN

Objective To evaluate the clinical efficacy of percutaneous ultra-fine needle CO_2 splenoportography (CO_2-SP).Methods CO_2-SP and 3D-CE-MRA were performed in 36 patients.The imaging quality of the methods was compared by a scoring criterion setup based on the visualization of the trunk,intrahepatic branches of the portal vein and collateral vessels.Results Transient mild abdominal discomfort was presented in 19 patients(52.8% )receiving CO_2-SP.One patient developed snbcapsular splenic hematoma and was discharged with clinical stability several days later after conservative treatment. The imaging quality of the intrahepatic branches of the portal vein with CO_2-SP was much more superior to 3D-CE-MRA (the score was 232 and 198 respectively,t=4.52,P0.05 ).Conclusion Ultrafine needle CO_2-SP is a minimally invasive and safe procedure,able to provide dynamic and clearer imaging of the intrahepatic branches of the portal vein.

RESUMEN

0.05). Dysphasia resolved significantly after stent placement in both groups.The improvement of dysphasia was more significant in Group A than in Group B after 2 months of stent placement(1.37?0.56 in group A, 1.82?0.50 in group B,P=0.004).The median survival period was longer in Group A than in Group B (7 months vs 4 months).The mean survival period was also longer in Group A than in Group B (8.3 months vs 3.5 months).There was a statistically significant difference in the survival period between the two groups(P

RESUMEN

Objective To investigate the transfection and expression of p53 genes mediated by liposome and its feasibility in treatment of liver cancer by transcatheter arterial injection on rabbit VX2 hepatocarcinoma model.Methods pCMV-myc-p53 plasmids,LipofectAMINE and p53-LipofectAMINE complex were infused into tumor's feeding artery of rabbit VX2 hepatocarcinoma model,respectively,and then protein of cancer tissue was extracted,followed by measuring gene transfection and expression by western blot and immunohistochemistry,p53-LipofectAMINE complex in different doses were infused into tumor's feeding artery of rabbit VX2 hepatocarcinoma model with the gene transfection and expression detected by the same way.Results Liposome-mediated p53 gene injected through catheter could be successfully transfected and expressed in the cancer tissue of rabbit VX2 hepatocarcinoma model,with transfection efficiency higher than the gene delivery alone.The efficiency and the gene dose has dose-effect relationship.Condusions Treatment of liver cancer by transcatheter arterial injection of p53 genes mediated by liposome is a feasible and effective method,with wide prospect of application.(J Intervent Radiol,2007,16:109-114)
