RESUMO
Objective To investigate the inhibitory effects of medicinal serum of Shenqi Yiliu Formula on cell proliferation of gastric cancer MGC-803 cells;To discuss relevant mechanism. Methods After treated with different concentrations of medicinal serum of Shenqi Yiliu Formula, gastric cancer MGC-803 cells were tested by the following methods: MTT was employed to test the proliferation of gastric cancer MGC-803 cells; Flow cytometry was used to detect cell cycle; qRT-PCR was used to detect the genetic expressions of CDKN1B and CDKN1C;Western blot was employed to test the protein expressions of p27 and p57. Results When 3%, 5%and 10%medicinal serum of Shenqi Yiliu Formula was treated to MGC-803 cells for 24 h, 48 h and 72 h, proliferation of cells decreased significantly (P<0.01), with time- and dosage-dependent relationship. When 3%, 5% and 10% medicinal serum of Shenqi Yiliu Formula was treated to MGC-803 cells for 24 h, cells in G0/G1 increased, decreased in S. qRT-PCR results showed that compared with the blank control group and the negative control group, mRNA expressions of CDKN1B and CDKN1C of MGC-803 cells in medicinal serum all dose group increased significantly (P<0.01). Western blot results showed that compared with the blank control group, protein expressions of p27 and p57 of MGC-803 cells in medicinal serum all dose group increased significantly (P<0.01). Conclusion Medicinal serum of Shenqi Yiliu Formula can inhibit MGC-803 cells proliferation and the mechanism may be through adjusting CDKN1B, CDKN1C mRNA and proteins expression to intervene in the cell cycle.
RESUMO
AIM: To study the protective effect of medicinal serum of Jiangtang compound recipe on endothelial cells which were damaged by H2O2. METHODS: The effects of medicinal serum of Jiangtang compound recipe on cell viability, concentration of malondialdehyde (MDA), NO, endothelin-1 (ET-1) and activity of superoxide dismutase (SOD) were determined for human umbilical vein endothelial cells (ECV304) damaged by H2O2. RESULTS: The medicinal serum of Jiangtang compound recipe significantly improved the structural change of ECV304 cells damaged by H2O2, suppressed the production of MDA and the content of ET-1, increased activity of SOD and the rate of animate cells, and promoted secretion of NO. CONCLUSION: The medicinal serum of Jiangtang compound recipe can resist the injury of ECV304 caused by H2O2, playing a role in the protective effect.
RESUMO
Objective To study the effect of the serum contained Radix Astragali, Hirudo or their compound on the growth cycle and apoptosis of rat mesangial cells (MC).Methods The serum contained the extract of high-concentration of Hirudo, the serum contained the extract of high-concentration of Radix Astragali, and the serum contained the extract of high-concentration of Hirudo and the extract of low-concentration of Radix Astragali were prepared. The cultured MC were measured by flow cytometer to observe the changes in their growth cycle and apoptosis. The morphological changes of apoptotic cells were observed.Results The medicinal serums can keep the most MC in the stage of G0/G1, and the significant difference was existing in comparison with that of the control group (P
