Objective　To investigate the effects of TNP-470 on the growth of a human malignant glioma cell line SHG-44 in vivo and in vitro. Methods　The colorimetric MTT assay, soft agar culture, flow cytometry，light and electron microscopy were used to determine the proliferation, the cloning efficiency, cell cycle and the morphological changes of SHG-44 cells as well as the growth of its xenografted tumor. Results　TNP-470 (20～2 000 ng/ml) significantly inhibited the proliferation of SHG-44 cells in vitro (the 50% inhibitory concentration was 200 ng/ml). Cloning efficiency reduced obviously. The number of cells in G0/G1 phase increased, while that in S, G2/M phases decreased significantly. Weight and volume of xenografted tumors treated with TNP-470 (30 mg/kg, injected subcutaneously every other day) reduced notably. Furthermore, there were necrotic area and apoptosis in the tumor. No severe side effect of TNP-470 was found in this study. Conclusion　The inhibitory effect of TNP-470 on the growth of SHG-44 cells correlates with its functions of regulating cell cycle and inducing apoptosis, which suggests that the angiogenesis inhibitor TNP-470 has strong inhibitory effect on human malignant gliomas.

Objective:To research the stability of Dazhu Hongjingtian injection combined with four different infusion solutions (0. 9% sodium chloride injection, 5% glucose injection, fructose injection, xylitol and sodium chloride injection) . Methods:The insolu-ble particles and pH value of Dazhu Hongjingtian injection in 0, 0. 5,1,2,4 and 8h after the combination were detected by the methods described in China Pharmacopeia ( 2010 edition ) . Results: Dazhu Hongjingtian injection combined with the four infusion solutions showed no significant changes in appearance and pH value in 8h. The number of insoluble particles in Dazhu Hongjingtian injection combined with 0. 9% sodium chloride injection and 5% glucose injection met the requirement in the pharmacopeia, and that in 0. 9%sodium chloride injection was lower than that in 5% glucose injection. The quantity of insoluble particles in Dazhu Hongjingtian injec-tion combined with fructose injection exceeded the standard level, and showed remarkable change in the fourth hour. The quantity of insoluble particles in xylitol and sodium chloride injection slightly exceeded the standard. Conclusion: Dazhu Hongjingtian injection can be mixed with 0. 9% sodium chloride injection and 5% glucose injection, and fructose injection and xylitol and sodium chloride in-jection are not suitable for the solvent of Dazhu Hongjingtian injection. Although there is no instruction indicating that 0. 9% sodium chloride injection can be used as the suitable solvent for Dazhu Hongjingtian injection, the results of the experiment can be reasonable reference for diabetes patients treated with Dazhu Hongjingtian injection.
