Methods: A total of 40 SPF grade Kunming mice were selected to establish H22 liver cancer model, and then the mice were divided into 4 groups at random with ten mice in each group. Group A was given saline lavage treatment, Group B was treated with 5-FU by intraperitomeal injection, Group C was treated with LTA by lump body injection; Group D was treated with LTA by lump body injection and 5-FU by intraperitomeal injection. Two weeks after the treatment, the mice in each group were executed and the tumor tissue was stripping and weighted, and the tumor growth inhibition ratio was calculated. Then the tumor tissue was processed for conventional embedding, sectioned to observe the expression of caspase-3, EGFR, TGF-α by immunohistochemical staining method. Results: The tumor inhibitory rate o f Group D was significantly higher than Groups B and C(P<0.05); B, the tumor inhibitory rate o f Group B had no statistical difference compared with Group C(P>0.05). The IDO values of TGF-α, EGFR proteins in Groups B, C, D mice tumor tissue were significantly lower than that in group A(P<0.05); while IDO value of caspase-3 in Groups B, C, D group mice tumor tissue was significantly higher than that in Group A(P<0.05). The IDO value of TGF-α, EGFR in Group D mice tumor tissue were significantly lower than that in Groups B and C; While IDO value of aspase-3 in Group D was significantly higher than that in Groups B and C(P<0.05). Conclusions: LTA combined with 5-FU can effectively inhibit the tumorigenesis of H22 tumor bearing mice, increase the caspase-3 protein expression, inhibit TGF –α and EGFR protein expression, further promote tumor cell apoptosis and play a synergistic antitumor effect.展开更多

[Method] The H= tumor cells were transplanted in the right axillary skins of mice. The tumor- bearing mice were randomly divided into five groups, including control group, CTX group （20.0 mg/kg） and buddlejasaponin IV treatment groups （0.25, 0.50 and 1.00 mg/kg）. There were 10 mice in each group. During the treatment, the body weights and survivals of mice in all groups were recorded. The buddlejasaponin IV was in- jected into the abdominal cavities of mice, which lasted for 10 consecutive days. All the mice were slaughtered the next day. The tumors in the abdominal cavities were tanked out and weighed. The tumor inhibition rate, spleen index and thymus index, as well as SOD activity, MDA content, GGT activity and AKP activity in serum were determined. [Result] Compared with the control group, the high- and middle- dosage buddlejasaponin IV treatment groups all showed significant （P〈0.01） inhibito- ry effects on transplanted H22 tumor in mice with tumor inhibition rates of 56.96% and 50.63%, respectively. Compared with those in the control group, the SOD ac- tivity of mice in the high-dosage buddlejasaponin IV treatment group was significant- ly increased （P〈0.05）, and the MDA contents, GGT and AKP activities in mice in the high-, middle- and low-dosage buddlejasaponin IV treatment groups were all sig- nificantly reduced （P〈0.01）. There were no significant differences in all the indexes, except SOD activity, between the CTX and control groups. [Conclusion] Buddlejas- aponin IV has certain inhibitory effect on H22 tumor, of which the mechanism might be related to antioxidation capacity in body.展开更多

Methods: The xenograft model was established using injected subcutaneously H22 cells into the right axilla of the mice. Each group was treated with different doses of GPC and Endostar. All these treatments were maintained for 10 days, and mice were sacrificed. The xenograft tumors in mice were measured. The proliferation activity level of H22 cells was determined by MTT assay, and the levels of vascular endothelial growth factor(VEGF) protein were examined by immunohistochemistry. Results: When treated with 50, 100 and 200 mg/kg of GPC and Endostar, the tumor inhibition rates were 13.17%, 23.37%, 36.15% and 14.71%, respectively. The tumor weight of xenograft was significantly lighter in high GPC group than the control group(P < 0.05). The ODs in GPC groups were 0.835, 0.666 and 0.519, respectively. The absorbances in middle and high GPC groups were statistically significant, compared with control group(P < 0.01). Immunohistochemical technique showed the expression of VEGF of the GPC groups was downregulated significantly compared with the control group(P < 0.01). Conclusion: GPC can inhibit the growth of hepatocellular carcinoma H22 cell xenograft in mice. The inhibition of angiogenesis by the down-regulation of VEGF expression may play a key role in the anti-neoplastic effect of GPC.展开更多
