RESUMO
<p><b>OBJECTIVE</b>To evaluate the efficacy and toxicity of paclitaxel with low-dose cisplatin and 5-fluorouracil continuous infusion in the treatment of advanced gastric carcinoma.</p><p><b>METHODS</b>The patients were treated with paclitaxel liposome 60 mg/m(2) i.v. gtt on d1, 8, 15, DDP 15 mg×m(-2)×d(-1) by i.v. gtt on d1-5, 5-Fu 500 mg×m(-2)×d(-1) by civ for 120 h, administered every 21 days.</p><p><b>RESULTS</b>Out of the whole group, 3 cases achieved CR, 29 cases achieved PR with an ORR of 54.2% and median TTP of 7.1 months. Out of 40 cases in the primary treatment, 3 cases achieved CR, 22 cases achieved PR with an ORR of 62.5% and median TTP of 7.6 months. Out of 20 evaluable retreated cases, no case achieved CR, 7 cases achieved PR with an ORR of 36.8% and median TTP 6.3 months. The main toxicities were hematological toxicities, nausea and vomiting of grade I-II.</p><p><b>CONCLUSION</b>The combination regimen of paclitaxel, low-dose cisplatin and 5-fluorouracil is effective and well tolerated for patients with advanced gastric carcinoma, especially for primary treatment cases. It is worthy of further study.</p>

OBJECTIVE@#To investigate the apoptosis of human breast cell line MCF-7 cells induced by gemcitabine and radiation.@*METHODS@#The MTT method was applied to study the growth inhibition of MCF-7 treated with gemcitabine, radiation, gemcitabine and radiation. The apoptosis index (AI) was analyzed by flow cytometry. The morphology of the MCF-7 cells apoptosis was observed by transmission electron microscopy.@*RESULTS@#When MCF-7 cells were treated with gemcitabine at different concentrations for 24 h, the cell growth inhibition rate was increased in a concentration-dependent manner. The apoptotic indexes (AI) of MCF-7 of four groups by flow cytometry revealed. The AI of (R+D) group was significantly different from those of the radiation group and the gemcitabine group (P<0.05). Condensed chromation, nuclear fragmentation and apoptotic body of MCF-7 cells were found by transmission electron microscope.@*CONCLUSION@#The apoptosis of human breast cancer cell line, MCF-7 cells, could be induced by gemcitabine. Gemcitabine can significantly enhance the radiation-induced apoptosis of MCF-7 cells.
