Glioma is the most frequently observed primary tumor of the central nervous system in adults. Among the glioma cases, more than three quarters of patients suffer from high-grade gliomas. High-grade glioma is not only a high-degree malignant tumor but is also an easily recurring disease after surgery with a very poor prognosis. Radiotherapy plus concomitant chemotherapy after operation is the standard treatment strategy for high-grade gliomas, which could increase the survival rate of patients. However, the curative effect is really not satisfactory because it could only guarantee a limited survival time. Over the recent years, molecular-targeted treatment has increasingly drawn the attention of scholars with the continuous development in glioma treatment, thereby becoming the hotspot among researchers. Vascular endothelial growth factor (VEGF) is highly expressed in glioma and in the tissues surrounding the cancer cells. VEGF could regulate tumor growth by inducing endothelial cell proliferation, growth, migration, and by increasing the vascular permeability. Hence, VEGF becomes an effective target for the treatment of glioma. Bevacizumab is a monoclonal antibody that can specifically prevent the combination of VEGF and its receptor, thereby inhibiting the formation of tumor blood vessels. At the same time, bevacizumab can normalize the tumor blood vessels, improve the permeability of blood vessels, and increase the effectiveness of drug concentration in the tumor tissues, thereby achieving anticancer efficacy. In this paper, the mechanism of bevacizumab is introduced. The research progress in the application of bevacizumab alone, as well as in combination with chemotherapy or other drugs, for the high-grade glioma treatment will be summarized.

Objective Acute liver failure is one of the significant causes of death clinically.It is important to explore new serum markers of liver injury for early diagnosis and prognosis prediction of severe liver disease.Hepassocin ( HPS) is a liver-specific mitogenic growth factor.Our study is intended to investigate the correlation between HPS serum levels and the degree of liver injury.Methods Firstly, a mouse model of acute liver injury was constructed via intraperitoneally injection with different doses of CCl4 .Then the survival rate, alanine aminotransferase ( ALT) , aspartate aminotransferase ( AST) and the pathological changes in the liver were detected.Meanwhile, ELISA assay was performed to detect the serum level of HPS.In addition, the mRNA level and protein level of HPS were detected by real-time PCR and Western blotting, respectively.Results The mortality rate was increased and the liver damage was aggravated with the increase of the CCl4 dose.Besides, the ALT and AST levels were also increased in a dose-dependent manner.Additionally, the mRNA and protein levels of HPS were significantly up-regulated and closely related to the degree of the liver injury in the model. Conclusion HPS can be used as a new marker of liver injury in mice.

This study aims to analyze and compare the effect of cell wall-broken decoction pieces, conventional decoction pieces and conventional powder of Rhodiolae Crenulatae Radix et Rhizoma on the intestinal flora of normal mice. The conventional bacterial culture and PCR-DGGE (polymerase chain reaction-denaturing gradient gel electrophoresis) were adopted for the mice after the oral administration for 14 days. According to the bacterial culture results, the 1/8 dose cell wall-broken decoction pieces group showed fewer Enterococcus and Escherichia coli bacillus but more Lactobacillus and Bifidobacterium than the conventional decoction pieces group and the traditional powder group (P <0.05). Meanwhile, on the basis of the PCR-DGGE results, the 1/8 dose cell wall-broken decoction pieces group revealed the highest Shannon-Wiener index (H) and species richness (S) among the seven groups, with extremely significant differences compared with the normal group (P <0.01), significant differences compared with the conventional decoction pieces group and the conventional powder group (P <0.05) and a high intra-group similarity. In conclusion, the long-term intake of 1/8 dose Rhodiolae Crenulatae Radix et Rhizoma cell wall-broken decoction pieces showed a certain effect in regulating intestinal tract by promoting the growth of Lactobacillus and Bifidobacterium. Furthermore, the intestinal flora community will become more stable.
