摘 要:目的研究南瓜蛋白(CUS)联合胰腺癌常用化疗药物吉西他滨(GEM)、氟尿嘧啶(5-FU)、紫杉醇(erx)、顺铂(DDP)对人胰腺癌细胞株BxPC-3的增殖抑制作用。方法采用磺酰罗丹明B(SRB)比色法测定CUS分别与GEM、5-FU、PTX、DDP联用对体外培养的BxPC-3细胞的增殖抑制作用;应用集落形成实验测定CUS分别与GEM、5-FU、PTX、DDP联用对体外培养的BxPC-3细胞集落形成的影响;用金氏公式判断药物联用的协同效果。结果CUS联用GEM、5-FU、HIX、DDP对BxPC.3细胞的增殖抑制率均大于各药单用的抑制率,q〉0.85;CUS与胰腺癌常用化疗药物均在低浓度范围内联用的相加效果明显。CUS联用GEM、5-FU、PTX、DDP对BxPC-3细胞的集落形成抑制率均大于各药单用的抑制率,q〉1.15。结论CUS联合GEM、5-FU、PTX、DDP常用化疗药物对体外培养的BxPC-3细胞的生长抑制具有较好的协同作用。Objective To investigate the inhibitory effect of cucurmosin (CUS) combined with the commonly used chemotherapeutic drugs for pancreatic cancer in clinical practice including Gemcitabine (GEM) , Fluorouracil (5-FU) , Paclitaxel (PTX) and Cisplatin (DDP) on cell proliferation of human pan- creatic cancer cell line BxPC-3. nehtods Sulforhodamine B (SRB) assay was used to detect the inhibition on the cell proliferation of BxPC-3 cells in vitro after the treatment of CUS combined with GEM, 5-FU, PTX and DDP, respectively. Colony formation assay was also conducted and Jin' s formula was used to assess the synergistic effect of these combinations. Results The inhibition rate of CUS combined with GEM, 5-FU, PTX and DDP were all higher than those of each drug alone ( q 〉 0.85 ) , which became obvious in low con- centrations. The colony formation inhibition rate of CUS combined with GEM, 5-FU, PTX or DDP were all higher than each single drug treatment (q 〉 1.15). Conclusion CUS could enhance the cell growth inhibi- tion of GEM, 5-FU. PTX and DDP in BxPC-3 cells in vitro with a good svnergistic effect.
