28 ml /kg every two days;WenYuJin with low dose group were cheated by oral gavage administration of WenYuJin alcohol extract at dose of 1.4 g/kg every day,WenYuJin with high dose group were cheated by oral gavage administration Sirolimus chemical structure of WenYuJin alcohol extract at dose of 2.8 g/kg every day,WenYuJin with low doses associated vincristine group were oral gavaged of WenYuJin alcohol extract at dose of 1.4 g/kg every day and intraperitoneally administered vincristine at dose of 0.28 ml /kg every two days;WenYuJin with high doses associated vincristine group were oral gavaged administration of WenYuJin alcohol extract at dose of 2.8 g/kg every
day and intraperitoneally administered vincristine at dose of 0.28 ml /kg every two days,with a total experiment period of 14 days. The next day after the last treatment, we killed the nude mice by taking off the cervical spine,cut tumors and weighed them, calculated the tumor inhibition learn more rate, saved the tumor specimens for detecting the expression of GCS by PCR, Western Blot and immunohistochemical. Results: 1. Tumor weight and tumor inhibition rate: WenYujin with high dose associated vincristine group was obviously
lighter than model group and vincristine, its tumor inhibition rate was 59.28%, tumor weight were respectively 0.283 ± 0.118, 0.695 ± 0.269, 0.592 ± 0.311, P < 0.05; WenYuJin with low doses associated vincristine group had no significantly differences compared with model group and vincristine group, (P > 0.05), and its tumor inhibition rate was 39.14%;the tumor
weight of WenYuJin group were 0.517 ± 0.309, 0.477 ± 0.119, they had no significantly differences compared with model group and vincristine group(P > 0.05),and between the two groups, they also had no significant difference (P > 0.05). 2. GCS mRNA expression in the PCR: The GCS mRNA expression of vincristine were significantly higher than the model group (2.39 ± 0.39, 1.44 ± 0.28, P < 0.05); WenYuJin with high dose group and WenYuJin associated vincristine were significantly lower than Galeterone the model group, (1.11 ± 0.13, 1.02 ± 0.34, 0.74 ± 0.23, 1.44 ± 0.28, P < 0.05), However, the comparison between WenYuJin associated vincristine groups, there was no statistically significant difference (P > 0.05); and there was no statistically significant difference between WenYuJin with low dose group and model group (P > 0.05). 3. Wester blot: GCS protein expression in vincristine group were significantly higher than the model group (1.84 ± 0.18, 1.24 ± 0.06, P < 0.05); WenYuJin with high dose group and WenYuJin associated vincristine were significantly lower than the model group, (0.88 ± 0.17, 0.54 ± 0.04, 0.50 ± 0.06, 1.24 ± 0.06, P < 0.05), However, the comparison between WenYuJin associated vincristine groups, there was no statistically significant difference (P > 0.
