摘　　要：目的观察基质金属蛋白酶抑制剂SB-3CT联合多西他赛对前列腺癌PC-3细胞存活率的影响。方法不同浓度的SB-3CT（5～20μmol／L）和多西他赛（0．1—1000．0nmol／L）分别或联合作用于细胞，采用水溶性四唑盐WST-1检测细胞存活率，药物联合指数法（CI）分析两种药物之间的相互作用。结果与单一用药比较，两药联合作用可以显著降低PC-3细胞存活率（P〈0．01），CI指数分析显示：在SB-3CT浓度为20μmol／L时，与多西他赛有轻中度的协同作用（0．5995〈CI〈0．9652）。结论SB-3CT联合多西他赛对PC-3的存活率有显著的抑制作用，且两药具有协同效应，可望成为一种潜在的治疗去势抵抗性前列腺癌的联合治疗方案。Objective To investigate the effect of matrix metalloproteinase inhibitor SB - 3CT combine with docetaxel on proliferation of prostate cancer cell PC - 3. Methods The PC - 3 cells were treated with SB -3CT （5 -20 μ mol/L） or/and docetaxel （0. 1 -1 000.0 nmol/L）in different concentra- tions. The cell viability was detected with WST - 1 assay. Interactive effects of drugs were analyzed with combination index. Results Matrix metalloproteinase inhibitor SB -3CT combine with docetaxel could re- duce the viability of PC - 3 cells significantly compared with any single drug （ P 〈 0. 01 ）. When concentra- tion of SB - 3CT was 20 μmoL/L, mild to moderate synergistic effects were shown （ 0. 599 5 〈 CI 〈 0. 965 2）. Conclusion The viability of PC - 3 could be inhibited by combine therapy, and synergistic effects between two drugs were determined. It might be a potential therapy for castration resistant prostate
