文题释义:

多发性骨髓瘤:多发性骨髓瘤患者体内会出现恶性浆细胞大量增殖的情况,导致大量单克隆免疫球蛋白的出现,对患者的肾功能造成不同程度的损害,并容易导致高黏滞综合征、反复感染等。在疾病的发生和发展过程中,多发性骨髓瘤细胞的各项生物学活动均与骨髓微环境之间存在密切的关系。
黄芪多糖:黄芪中含有大量的黄芪多糖,是一种具有生物活性的物质。经过研究发现,黄芪多糖具有多种药理功效,包括抗氧化和抗肿瘤以及增强免疫力等。以往也有学者通过研究发现,黄芪多糖可以对骨髓间充质干细胞的增殖情况产生一定的影响。

 

背景:骨髓间充质干细胞可通过产生多种细胞因子,可以为骨髓瘤细胞的生长增殖提供一定的支持。
目的:探讨黄芪多糖对多发性骨髓瘤患者骨髓间充质干细胞增殖情况以及细胞因子分泌情况的影响。
方法:取正常人与多发性骨髓瘤患者骨髓,通过密度梯度离心法分离得到骨髓间充质干细胞,行传代培养及鉴定。收集第3代骨髓间充质干细胞,使用酶标仪法描绘出生长曲线。使用MTT法及流式细胞术分别检测不同质量浓度(0.5,1,2,4,6,8 g/L)黄芪多糖对骨髓间充质干细胞增殖及细胞周期的影响。使用ELISA法检测细胞中白细胞介素1β和白细胞介素6的表达水平。

结果与结论:①正常人与多发性骨髓瘤患者骨髓间充质干细胞均呈现出CD34阴性和CD44阳性表达,表明所获得的是骨髓间充质干细胞;②正常人骨髓间充质干细胞倍增时间显著短于多发性骨髓瘤患者的骨髓间充质干细胞;③当黄芪多糖干预的质量浓度为1和2 g/L时,多发性骨髓瘤组的细胞增殖率显著高于正常对照组;质量浓度为6和8 g/L时,细胞增殖率显著低于正常对照组;④与1 g/L黄芪多糖干预的正常人骨髓间充质干细胞相比,1 g/L黄芪多糖干预的多发性骨髓瘤患者骨髓间充质干细胞的G0 /G1期所占比例较少,S期和G2/M期所占比例增加;⑤多发性骨髓瘤患者骨髓间充质干细胞的白细胞介素1β和白细胞介素6水平均显著高于正常人;⑥经0.5,1和2 g/L黄芪多糖干预后,多发性骨髓瘤患者骨髓间充质干细胞中的白细胞介素1β和白细胞介素6水平显著下降;⑦结果表明,一定质量浓度的黄芪多糖可以促进多发性骨髓瘤患者骨髓间充质干细胞的增殖及白细胞介素1β和白细胞介素6水平的下降。

Abstract:

BACKGROUND: Bone marrow mesenchymal stem cells can produce a variety of cytokines to provide some support for the growth and proliferation of myeloma cells.

OBJECTIVE: To investigate the effects of astragalus polysaccharides on the proliferation of bone marrow mesenchymal stem cells from patients with multiple myeloma and cytokine secretion.

METHODS: Bone marrow mesenchymal stem cells were isolated by density gradient centrifugation from the bone marrow of a healthy volunteer and a multiple myeloma patient, and were cultured and identified. Passage 3 bone marrow mesenchymal stem cells were collected, and the growth curve was depicted by the enzyme marker method. MTT method and flow cytometry were used to detect the effects of different concentrations (0.5, 1, 2, 4, 6, 8 g/L) of astragalus polysaccharides on the proliferation and cell cycle of bone marrow mesenchymal stem cells. The expression levels of interleukin-1β and interleukin-6 were detected by ELISA method.

RESULTS AND CONCLUSION: Bone marrow mesenchymal stem cells from both the healthy control and multiple myeloma patient showed negative expression of CD34 and positive expression of CD44. The obtained cells from two sources had the characteristics of bone marrow mesenchymal stem cells. Cells from the healthy control had significantly shorter doubling time than those from the myeloma patient. After treated with 1 and 2 g/L astragalus polysaccharide, cell proliferation rate in the multiple myeloma group was significantly higher than that in the healthy control group; after treated with 6 and 8 g/L astragalus polysaccharide, the cell proliferation rate was significantly lower in the multiple myeloma group than in the healthy control group. After treated with 1 g/L astragalus polysaccharide, compared with the healthy control, the proportion of bone marrow mesenchymal stem cells from the multiple myeloma patient in G0/G1 phase was significantly decreased, while the proportions of cells in both S phase and G2/M phase from the myeloma patient were significantly increased. Interleukin-1β and interleukin-6 levels of bone marrow mesenchymal stem cells from the patient with multiple myeloma were significantly higher than those of cells from healthy control. After intervention with 0.5, 1, 2 g/L astragalus polysaccharide, the interleukin-1β and interleukin-6 levels of bone marrow mesenchymal stem cells from the patient with multiple myeloma were all significantly decreased. In conclusion, a certain concentration of astragalus polysaccharides can promote the proliferation of bone marrow mesenchymal stem cells and decrease the levels of interleukin-6 and interleukin-β in patients with multiple myeloma.
