1.Interventional Treatment in Cancer of Rectum(Report of 36 Cases)
Journal of Interventional Radiology 1994;0(04):-
36 patients with cancer of rectum treated by infusion chemotherapy after selective inferior mesenteric arteriography were reported.All patients had good result.A- mong them 13 cases without embolization,showed vascular blockage,decrease in size of tu- mor on follow up angiographies and reduction of bleeding during operation.The authors be- lieved that arterial infusion chemotherapy not only can kill tumor cells hut also resulted in degenerative change of vascular endothelia,necrosis and vascular occlusion.Simultaneously it can also stimulate the tissue in the periphery of tumor to produce inflammatory cell infil- tration and fihroplasia,suppress the grwoth of tumor,prevent the spread of tumor cells and metastasis;thus prolong the survival time.Interventional treatment is of great value to can- cer of rectum.The indications were recommended.

To investigate the expression of laminin receptor in different bile duct carcinoma cell strains, a peritoneum infiltration screening model was established to screen out the different metastatic cell strains of bile duct carcinoma. Invasive experiments in vitro were adopted to validate the results. The difference of LNR expression was compared both in the high and low cell strains by flow cytometry analysis. The results showed that by using the peritoneum infiltration screening model, high and low metastatic QBC939 cell strains were successfully screened out. Invasive experiments in vitro also proved that the invasive ability of high cell strain was stronger than that of the low one. The positive rate of LNR in high strains (36 36?9 22)%was higher than that in the low ones(13 17?3 43)%, and the difference was significant( P

This study was designed to investigate modulation of phosphorothioate oligodexynucleotides of laminin receptor on MMP 2 and MMP 9 gene expression in human bile duct carcinoma cells. Treated with a concentration of 12?mol/L LNR AS OD in cuture medium, the relative MMP 2 and MMP 9 mRNA level at 72h in human bile duct carcinoma cells was evaluated by reverse transcriptase polymerase chain reaction. The results showed that the expression of MMP 2 and MMP 9 dropped obviously by AS OD group as compared with control group. The relative expression level of MMP 2 and MMP 9 gene mRNA decreased about 33 2% and 23 9% respectively. It is suggested that LNR AS OD is the regulator of MMP 2 and MMP 9 gene expression. It can decrease MMP 2 and MMP 9 gene expression in human bile duct carcinoma cells. Understading the regulation of MMP 2 and MMP 9 gene expression in human bile duct carcinoma cells might contribute to the development of a new preventive and theraputic strategy for tumor invasiveness.

Objective To study the role of autophagy in the curcumin (Cur) enhancing the chemosensitivity of the colorectal cancer LoVo cells to irinotecan (CPT-11). Methods The LoVo cells were separated into 4 groups:the control group,the Cur group,the CPT-11 group and the Mix group.Western blot assay was applied to determine the expression of autophagy-related protein LC3-Ⅱ and P62. LC3-Ⅱ was detected by immunofluorescence method. Transmission electron microscopy was used to detect the autophagosome. CCK-8 assay was applied to detect the cell growth inhibitory rate of LoVo cells ,which were pre-treated with autophagy inhibitor 3-MA before 24-h treatment of Cur and/or CPT-11. Western blot assay was applied to detect the expression of LC3- Ⅱ and P62. Results The mixed treatment significantly increased the expression of LC3-Ⅱwhile decreased P62 expression,compared with the Cur and CPT-11 treatments. The autophagosomes in cells of Mix group were significantly more than those in cells of the Cur and Cpt group. Pre-treatment of 3-MA significantly reduced cell growth rate in the Cur group,the Cpt group and the Mix group. Pre-treatment of 3-MA significantly decreased the expression of LC3-Ⅱ,while increased P62 expression,compared with the Mix group. Conclution Combinations of curcumin and CPT-11 could enhance the chemosensitivity of LoVo cells to CPT-11,which might be related to the activation of autophagy.
