Abstract: Background At present,long-term treatment of acute myeloid leukemia (AML) still faces multiple challenges such as high recurrence rate,treatment-related death risks and chemotherapy-related toxic and side effects.As an new chemical compound (artesunate as its derivative) which has been extracted from compositae plants,artemisia annua for the first time by Chinese scholars,artemisinin has gradually attracted widespread attention in recent years in the treatment of leukemia and cancer.Objective To explore the effects of artesunate on proliferation and apoptosis of human AML stem cells and K562 cell line.Methods Density gradient method was performed to separate AML stem cells in bone marrow fluid of 24 children with newly diagnosed or relapsed AML n who met inclusion criteria and were treated in the Department of Hematology,Henan Children's Hospital,from October 2016 to October 2018.The AML K562 cell line was purchased for research.AML stem cells and K562 cell line were equally divided into control group and experimental group (control group 1 and experimental group 1,control group 2 and experimental group 2 in turn).The control group 1 and control group 2 were not given artesunate for intervention.The experimental group 1 and experimental group 2 were given artesunate solution at a final concentration of 12.5,25.0 and 50.0 μg/ml,respectively (marked as experimental subgroup 1 and experimental subgroup 2 at a final concentration of 12.5,25.0 and 50.0 μg/ml).The survival of AML stem cells and K562 cells was observed by cell counting method.The growth and inhibition condition were detected by MTT assay.The apoptosis was detected by flow cytometry.Results At 48 h and 72 h after intervention,survival rate of AML stem cell in experimental subgroup 1 at a final concentration of 12.5,25.0 and 50.0 μg/ml was lower than that in control group 1 (P <0.05).At 72 h after intervention,survival rate of AML stem cell in experimental subgroup 1 at a final concentration of 25.0 and 50.0 μg/ml was lower than that in experimental subgroup 1 at a final concentration of 12.5 μg/ml (P<0.05).At 48 h and 72 h after intervention,survival rate of AML K562 cell line in experimental subgroup 2 at a final concentration of 12.5,25.0 and 50.0 μg/ml was lower than that in control group 2 (P<0.05).At 72 h after intervention,survival rate of AML K562 cell line in experimental subgroup 2 at a final concentration of 25.0 and 50.0 μg/ml was lower than that in experimental subgroup 2 at a final concentration of 12.5 μg/ml (P<0.05).At 24 h,48 h and 72 h after intervention,growth inhibition rate of AML stem cell in experimental subgroup 1 at a final concentration of 12.5,25.0 and 50.0 μg/ml was higher than that in control group 1 (P<0.05).At 48 h and 72 h after intervention,growth inhibition rate of AML stem cell in experiment subgroup 1 at a final concentration of 25.0 and 50.0 μg/ml was higher than that in experimental subgroup 1 at a final concentration of 12.5 μg/ml (P<0.05).At 24 h,48 h and 72 h after intervention,growth inhibition rate of AML stem cell in experimental subgroup 2 at a final concentration of 12.5,25.0 and 50.0 μg/ml was higher than that in control group 2 (P<0.05).At 48 h and 72 h after intervention,growth inhibition rate of AML stem cell in experiment subgroup 2 at a final concentration of 25.0 and 50.0 μg/ml was higher than that in experimental subgroup 2 at a final concentration of 12.5 μg/ml (P<0.05).At 48 h after intervention,apoptosis rate of AML stem cells in in experimental subgroup 1 at a final concentration of 12.5,25.0 and 50.0 μg/ml was higher than that in control group 1 (P<0.05).At 48 h after intervention,apoptosis rate of AML stem cells in experimental subgroup 1 at a final concentration of 25.0 and 50.0 μg/ml was higher than that in experimental subgroup 1 at a final concentration of 12.5 μg/ml (P<0.05).At 48 h after intervention,apoptosis rate of AML stem cells in experimental subgroup 2 at a final concentration of 12.5,25.0 and 50.0 μg/ml was higher than that in control group 2 (P<0.05).At 48h after intervention,apoptosis rate of AML stem cells in experimental subgroup 2 at a final concentration of 25.0 and 50.0 μg/ml was higher than that in experimental subgroup 2 at a final concentration of 12.5 μg/ml (P<0.05).Conclusion Artesunate can effectively inhibit proliferation of AML stem cells and K562 cell line and induce their apoptosis,which can provide experimental evidence for artemisinin treating AML.

摘要: 背景 目前急性髓系白血病(AML)长期治疗仍面临着高复发率、治疗相关死亡风险及化疗相关毒副作用等多重挑战。而青蒿素作为我国学者首次从菊科植物黄花蒿中提取出的化合物(青蒿琥酯为其类衍生物),其近年来在白血病、肿瘤疾病治疗中的作用逐渐引起广泛关注。目的 探究青蒿虎酯对人AML原代细胞、细胞株K562增殖和凋亡的影响。方法 采用密度梯度法分离2016年10月—2018年10月于河南省儿童医院血液科就诊的符合纳入标准的24例初治或复发AML患儿的骨髓液中的AML原代细胞。并购买AML细胞株K562进行研究。将AML原代细胞及细胞株K562均分为对照组和实验组(依次为对照组1和实验组1,对照组2和实验组2),其中对照组1及对照组2不予青蒿琥酯干预,实验组1和实验组2分别添加终浓度为12.5、25.0、50.0 μg/ml的青蒿琥酯液(分别记为终浓度12.5、25.0、50.0 μg/ml实验亚组1及终浓度12.5、25.0、50.0 μg/ml实验亚组2)。采用细胞计数法观察AML原代细胞、细胞株K562存活情况;采用MTT法检测其生长抑制情况;采用流式细胞术检测其凋亡情况。结果 终浓度12.5、25.0、50.0 μg/ml实验亚组1干预48 h、72 h AML原代细胞存活率低于对照组1(P<0.05);终浓度25.0、50.0 μg/ml实验亚组1干预72 h AML原代细胞存活率低于终浓度12.5 μg/ml实验亚组1(P<0.05)。终浓度12.5、25.0、50.0 μg/ml实验亚组2干预48 h、72 h AML细胞株K562存活率低于对照组2(P<0.05);终浓度25.0、50.0 μg/ml实验亚组2干预72 h AML细胞株K562存活率低于终浓度12.5μg/ml实验亚组2(P<0.05)。终浓度12.5、25.0、50.0 μg/ml实验亚组1干预24 h、48 h、72 h AML原代细胞生长抑制率高于对照组1(P<0.05);终浓度25.0、50.0 μg/ml实验亚组1干预48 h、72 h AML原代细胞生长抑制率高于终浓度12.5 μg/ml实验亚组1(P<0.05)。终浓度12.5、25.0、50.0 μg/ml实验亚组2干预24 h、48 h、72 h AML原代细胞生长抑制率高于对照组2(P<0.05);终浓度25.0、50.0 μg/ml实验亚组2干预48 h、72 h AML原代细胞生长抑制率高于终浓度12.5 μg/ml实验亚组2(P<0.05)。终浓度12.5、25.0、50.0 μg/ml实验亚组1干预48 h AML原代细胞凋亡率高于对照组1(P<0.05);终浓度25.0、50.0 μg/ml实验亚组1干预48 h AML原代细胞凋亡率高于终浓度12.5 μg/ml实验亚组1(P<0.05)。终浓度12.5、25.0、50.0 μg/ml实验亚组2干预48 h AML原代细胞凋亡率高于对照组2(P<0.05);终浓度25.0、50.0 μg/ml实验亚组2干预48 h AML原代细胞凋亡率高于终浓度12.5 μg/ml实验亚组2(P<0.05)。结论 青蒿琥酯能够有效抑制AML原代细胞及细胞株K562的增殖并诱导其凋亡,可为青蒿素治疗AML提供实验依据。
