摘要
目的:研究三氧化二砷(As2O3)联合奥曲肽在体外对人肝癌细胞株SMMC -7721增殖的作用,观察两药合用的效果。方法:采用MTT法测定药物的体外杀伤作用;用流式细胞术检测细胞周期变化;运用中效原理进行联合用药分析。结果:两药合用后在体外能显著抑制SMMC -7721生长;合用后的中效浓度分别为2 022、8 088μmol/L ,低于分别单用时的中效浓度;合用后可将肝癌细胞阻滞于S期;两药合用在抑制率>0 3时合用指数(CI)<1。结论:As2O3 联合奥曲肽在体外能显著增加两药单用时对人肝癌细胞株SMMC -7721的抑制作用,两药联合应用在抑制率>0 3时具有较好的抗肝癌协同作用。
OBJECTIVE:To study the cooperative effect of arsenic trioxide(As 2 O 3 )and octreotide on the proliferation of human hepatocellular carcinoma(HCC)SMMC-7721and to observe the combining effect of the two drugs.METHODS:The killing effect of drugs was determined by MTT;the cell cycle was determined by flow cytometry(FCM);the drug combination analysis was conducted by the moderate efficiency principle.RESULTS:The combination of arsenic trioxide and octreotide significantly inhibited cell proliferation of SMMC-7721in vitro;and the moderate efficiency concentration of As 2 O 3 and oc-treotide in combination was2.022μmol/L and8.088μmol/L respectively,which were lower than those when used singly.The combination of two drugs can inhibit HCC at the S-phase.The combination index was less than1if the combining domino offect of As 2 O 3 and octreotide was more than0.3.CONCLUSION:Combination of As 2 O 3 and octreotide in vitro can signifi-cantly increase the inhibition effect of each single one on the proliferation of SMMC-7721and the combination of two has a better anticarcinogenic effect when the domino offect of the combination is above0.3.
