Effect of Aitongxiao Granules Containing Serum on Proliferation and Apoptosis of SMMC-7721 and Bel-7404 Cells in Vitro / 中国中医药信息杂志

Objective To observe the anti-cancer effect in vitro of Aitongxiao Granules containing serum on SMMC-7721 and Bel-7404 liver cancer cells, thus revealing the anti-cancer mechanism of the treatment in adjusting proliferation and apoptosis. Methods Male Sprague-Dawley rats were administered by gastrogavage Aitongxiao decoction of 86.4, 43.2, 21.6 g/kg twice a day for 1 week. Using serum pharmacologic method, the proliferation of SMMC-7721 and Bel-7404 liver cancer cells were determined by MTT chromatometry after co-cultured with medicated serum containing different concentration of Aitongxiao decoction. The apoptosis of SMMC-7721 and Bel-7404 liver cancer cells were detected by flow cytometry. Results The research in vitro showed that Aitongxiao Granules containing serum low, medium and high dose groups had varying degrees of inhibition on hepatoma cells, and this inhibition showed a concentration dependence within a certain range. Aitongxiao Granules containing serum could induce apoptosis of human hepatoma SMMC-7721 cells and Bel-7404 cells. Conclusion Aitongxiao Granules showed effect of inhibiting proliferation and inducing apoptosis on SMMC-7721 and Bel-7404 cells in vitro.

Study on Quality Standard for Aitongxiao Granules / 中国药师

Objective:To establish the quality standard for Aitongxiao granules. Methods:TLC was used to identify Herba Hedy-otis Diffusa, Herba Scutell Barbatae, Radix Astragali and Radix Paeoniae Rubra in Aitongxiao granules, and the content of scutellarin was determined by HPLC. The stationary phase was a Kromasial C18 column (250 mm × 4. 6 mm,5μm), the mobile phase was metha-nol-3% acetic acid (33∶67), the flow rate was 1. 0 ml·min-1, the detection wavelength was at 335 nm, and the temperature was 25℃. Results:The characteristic TLC spots of the granule samples were the same as those of the standard samples without any inter-ference from the negative control. Scutellarin had a good linear relationship within the range of 2.18-10.90μg·ml-1(r=0.999 9), and the average recovery was 96. 65% with RSD of 1. 45﹪(n=6). Conclusion:The method is simple, accurate, reliable and repro-ducible, which could be used in the quality control of Aitongxiao granules.
