脐带血有助于脑卒中后恢复

一项小规模临床试验显示,在脑卒中发生后几天内注射脐带血,有助于缓解脑损伤、恢复认知和行动能力。

据英国《新科学家》杂志最近报道,美国杜克大学等机构的研究人员招募了10名年龄在45岁至79岁之间的志愿者参加试验,他们在发生大脑中动脉缺血性脑卒中后3天到10天间接受一次新生儿脐带血注射。

研究人员在国际期刊《干细胞转化医学杂志》上发表报告说,注射三个月后,所有患者的语言能力、视力和运动能力都有改善,日常生活自理能力提高,且没有明显不良反应。研究人员表示,这次试验没有设置对照组,对结果必须谨慎看待,不过志愿者接受治疗后的能力评分高于普通患者,显示可能有正面效果。

此前研究显示,给实验鼠注射人类脐带血,有助修复卒中后的脑部损伤,接受治疗的实验鼠恢复更快、生存率更高,脑部受损区域更小。这是因为脐带血中的干细胞能分泌特殊物质,促进脑细胞生长,减少炎症反应。

研究人员已经着手进行更大规模的试验,并设置对照组,进一步验证该疗法的效果。目前应对脑卒中的主要方法是药物溶栓,但需要在发作后几小时之内进行,大多数病人无法及时得到治疗。
