| 摘 要： | 本研究旨在探讨南瓜蛋白（CUS）与全反式维甲酸（ATRA）或亚砷酸（ATO）联用对人急性早幼粒细胞白血病NB4细胞增殖和凋亡的影响。以MTF比色法检测CUS与ATRA或ATO联用对NB4细胞的增殖抑制作用，用流式细胞术检测CUS与ATRA或ATO联用对NB4细胞凋亡的影响，用金氏公式判断两药联用的协同效果。结果表明，CUS与ATRA或ATO联合应用的抑制率均大于各药相应浓度单用的抑制率，其协同指数q值均〉0．85，并且两药均在低浓度范围内联用的协同效果明显。CUS与ATRA或ATO联合应用时NB4细胞的凋亡率均大于各药相应浓度单用时的凋亡率，其协同指数q值均〉1．15。结论：CUS与ATRA或ATO联用对NB4细胞增殖和诱导凋亡均有较好的协同作用。

| Abstract: | This study was aimed to investigate the proliferation inhibition and apoptosis induction of cucurrnosin （CUS） combined with all trans-retinoic acid （ATRA） or arsenic trioxide （ATO） on human acute promyelocytic leukemia cell line NB4. MTT method was used to determine the proliferative inhibition of CUS combined with ATRA or ATO on NB4 cells, and flow cytometry was used to determine the apoptosis induction effect of CUS combined with ATRA or ATO on NB4 cells. Jin＇s formula was used to assess the synergistic effect of this combinations. The results showed that, compared with single drug, the proliferation inhibitory ratio and apoptotic ratio of CUS combined with ATRA or ATO on NB4 cells was higher than CUS, ATRA and ATO alone. The synergistrc index （q） were all larger than 0.85, and the combined effects were significant at low concentrations. It is concluded that the CUS combined with ATRA or ATO synergistically increases the effects of proliferative inhibition and apoptosis induction on NB4 cells. |
