[摘要] 目的 探讨脐血与成人外周血中淋巴细胞分泌细胞因子能力的关系。方法 2011年6月—2014年6月,从该院选取60例健康产妇志愿者和召集60例正常志愿者,分为观察组和对照组作为临床研究对象。取60例健康产妇志愿者分娩后的脐带血进行研究,同时对60例正常志愿者的外周血进行研究,将两组志愿者的淋巴细胞分泌细胞因子能力进行对比,并分析讨论。结果 观察组和对照组志愿者在经过淋巴细胞分泌细胞因子能力的观察后,其中观察组淋巴细胞分泌细胞因子能力低于对照组(如脐血和成人外周血 IFN-γ、 TNF-α、TNF-α、 IL-2、IL-4的t值分别为 46.738 2、 65.267 7、 54.904 3、18.404 6,P<0.05)。结论 脐血与成人外周血中淋巴细胞分泌细胞因子能力相比较,在一定范围内充质干细胞和淋巴细胞分泌细胞因子能力有关,对植物血凝素诱导的淋巴细胞增殖具有抑制作用。

[Abstract] Objective To investigate the relationship between umbilical cord blood and adult peripheral blood lymphocyte cytokine secretion ability. Methods 60 cases of healthy pregnant volunteers and 60 cases of normal volunteers treated in our hospital from June 2011 to June 2014 were selected and divided into the observation group and the control group, the umbilical cord blood of 60 cases of healthy pregnant volunteers and peripheral blood of 60 cases of normal volunteers were taken for research, the cytokine secretory capacities of lymphocytes of the two groups were compared, analyzed and discussed. Results The observation showed the cytokine secretory capacity of lymphocytes in the observation group was lower than that in the control group, the differences in the IFN-γ, TNF-α, TNF-α, IL-2 and IL-4 between umbilical cord blood and adult peripheral blood were statistically significant (t=46.738 2, 65.267 7, 54.904 3, 18.404 6, P<0.05). Conclusion The comparison in cytokine secretory capacity of lymphocytes between umbilical cord blood and adult peripheral blood shows that the cytokine secretory capacity of mesenchymal stem cell is positively correlated with that of lymphocytes within a certain range, and it plays an inhibition role in lymphopoiesis induced by phytoagglutinin.

脐带血含有造血干细胞且易于采集[1],又因其免疫原性弱等优点,宜于临床疾病治疗,由此脐带血间的充质干细胞作为造血新种子细胞逐渐受到人们的关注[2]。国内外研究认为,骨髓间的充质干细胞可对混合淋巴细胞反应和丝裂原刺激的T细胞增殖过程进行抑制,通过转化生长因子自分泌发挥转化生长因子的免疫调节作用[3-5]。脐带血其间的充质干细胞对淋巴细胞的作用及影响在目前临床研究中尚未完全清楚,因此,该文作者对脐带血其间的充质干细胞对淋巴细胞的作用及影响进行相关研究,在2011年6月—2014年6月中在该院选取60例健康产妇志愿者和召集60例正常志愿者作为临床研究对象,观察患者淋巴细胞分泌细胞因子的表达,对脐带血与淋巴细胞分泌细胞因子的能力相关性进行研究,现报道如下。……
