Abstract:
Objective To analyze inhibitory effect on Wistar rattish hepatoma by endostatin, angiostatin,hyper-liquid hpiodol and a combination of these agents. Methods The rattish hepatoma models were randomly divided into 8 groups, including control group, lipiodol group, endostatin gene group, angiostatin gene group, endostaitin gene and angiostatin gene group, endostatin gene and lipiodol group, angiostatin gene and lipiodol group and endostatin gene, angiostatin gene and lipiodol group. Following treatment on Wistar rots with these agents or a combination of these agents, we measured the changes in tumor volume growth rate, metastases quantity rote, rattish life span, micmvessel density (MVD) value, apoptotic index(AI), vascular endothelial growth factor. Single factor variance test and Chi-square test were used for statistics. Results On the sixth day after treatment, the tumor volume growth rate of all the therapy groups were smaller than the control group. The therapeutic effect of the above mentioned two genes in combination with lipiodol was the best and the tumor volume growth rate was the smallest. On the eighteenth day after treatment, the numbers of pulmonary metastasis were(37.2±7.2)、(26.2±5.0)、(25.5±4.7)、 (26.2±3.9)、(14.9±2.6)、(19.1.4-2.8)、(20.2±2.7)and(6.1±1.2); the life span was(23.3± 4.4),(35.2±4.9),(28.2±3.6), (29.4±3.4), (38.3±6.7),(37.7±5.8), (36.4±5.5) and (59.8±9.4)days for each group respectively. The difference of the numbers of pulmonary metastases between the therapeutic groups and the control group was statistically significant(P<0.O1). The difference of the life span between the control group and the single gane group was not statistically significant, but the difference of the life span between the control group and the combination groups is statistically significant. MVD[(63.4±8.7)strip/high power field] in the lipiodol group was higher than the other therapeutic groups. However, the difference of MVD between the lipiodol group and the control group was not statistically significant. The apoptotie indexes in all the therapeutic groups were higher than the control group [(4.2±1.6)% ], the index in the two genes in combination with lipiodol group was the highest[ (19.6± 2.4)%]. The expression rate of VEGF in the control group was the highest(100%)and the rate in the two genes in combination with lipiodol group was the lowest(12.5%). Conclusions The inhibitory effect on Wistar rattish hepatoma of a combination of the above-mentioned two genes and lipiodol via transhepatic artery infusion is obviously superior to that of each individual agents.
