Aim To study the effect of IL-1β on pro-tein expression of vascular endothelial growth factor in glioma cells and plasma membrane microcapsule struc-ture protein caveolin-1 and plasma membrane vesicles in brain microvascular endothelial cells, and prelimi-narity discuss the possible mechanism of IL-1β opening blood tumor barrier. Methods The tumor barrier mod-el was established by transwell in vitro. The effect of IL-1β on the expression of VEGF in glioma cells and caveolin-1 in brain microvascular endothelial cells was dynamically monitored by Western blot. TEM was used to observe the number of plasma membrane vesicles of brain microvascular endothelial cells. Sodium fluores-cein leakage test was used to assess the permeability of blood tumor barrier after IL-1β. Results The tumor barrier model was successfully established by transwell in vitro. When IL-1β treated the model of blood tumor barrier,the expression of VEGF increased,and reached the peak at 60min,and recovered to the initial state at 120min. The permeability of the blood tumor barrier model was the highest at 60min. In addition,our re-sults also found that,the protein expression of plasma membrane microcapsule structure protein caveolin-1 and number of plasma membrane vesicles in brain mi-crocapsule endothelial cells reached peak at 60 min, subsequently reduced and returned to non drug state at 120min. Conclusion IL-1β increases blood tumor barrier permeability,which may be related to IL-1β in-creasing the number of plasma membrane vesicles through VEGF/ caveolin-1 pathway.

Purpose To explore the role of tumor necrosis factor-α( TNF-α) in the process of temozolomide ( TMZ) reduce glioma in-vasiveness and its possible mechanism. Methods C6 glioma cells of logarithmic phase were randomly divided into TMZ treatment (10, 30, 60, 120, 180, 240 min group) (n=15), dynamic monitoring content of TNF-αin the culture medium was measured by ra-dioimmunoassay, expression of p53 protein in C6 cells was detected with Western blotting method, and cell apoptosis was used with AnnexinV-FITC. A glioma invasiveness model was established in vitro and glioma invasiveness was determined by crystal violet stai-ning. Results For C6 cells, contents of TNF-αin the nutrient fluid and expressions of p53 protein in C6 cells obviously increased af-ter TMZ treatment and they achieved the peak at 120 min (P<0. 01), followed by decrease gradually. Glioma invasiveness was re-duced after TMZ acted on glioma in vitro. Conclusion TMZ can reduce glioma invasiveness by TNF-α, which this role may be is TMZ promote C6 cells release of TNF-α and increased TNF-α due to glioma cells apoptosis.

This study aimed to investigate the anti-apoptotic effects of Tangnaikang (TNK) on islet β cells in Zucker diabetic fatty (ZDF) rats.Six male fa/+ ZDF rats were took as the control group,while other thirty male fa/fa ZDF rats were divided into five groups at random:the model group,the metformin group,the high-,mediumand low-dose TNK groups,depending on their body weight and random blood glucose.Prior to the administration,fasting blood glucose and fasting insulin were measured by drawing blood with inner canthusl.Materials were prepared when administered for six weeks.Fasting blood glucose and fasting insulin were detected again.When the sections of the rat pancreatic tissue were embedded,the morphological changes of the islet were observed via HE staining,and the apoptosis of islet β cell were observed using TUNEL.Positive expression of Caspase-3,the transduction enzyme of cell death signal,was tested by immunohistochemical method.It was found that the fasting blood glucose of the (fa/fa) ZDF rats in the high-,medium-and low-dose TNK group was significantly improved after administration (P ＜ 0.01).The serum insulin of rats in the high-,medium-and low-dose TNK group arised compared with the model group,while the high-and low-dose TNK group showed differences in a statistical sense.Compared with the model group,the HOMA-IR of all the treatment group decreased,while significant difference was presented between the high-dose TNK group and the metformin group.HE staining showed that the morphology of the islet β cell of the rats in all the treatment group was improved.The results of TUNEL showed significantly apoptotic changes on islet β cell of the fa/fa ZDF rats.Compared with the model group,the positive expression of TUNEL in the metformin group and the high-dose TNK group were significantly reduced (P ＜ 0.05).The result of immunohistochemistry method showed that the protein levels of Caspase-3 in the metformin group and the high-dose TNK group decreased (P ＜ 0.05).In conclusion,it was demonstrated that TNK effectively reduced the apoptosis of islet β cells in fa/fa ZDF rats,which presented a protective effect.
