据发表于Journal of the American Society of Nephrology 的一项研究显示,对于肾脏疾病及肾损伤患者来说,从早产儿尿液中收集的细胞或可促进其肾脏的修复及再生。

据发表于Journal of the American Society of Nephrology 的一项研究显示,对于肾脏疾病及肾损伤患者来说,从早产儿尿液中收集的细胞或可促进其肾脏的修复及再生。

人类肾脏的发育始于妊娠期34周左右,随后细胞因自然老化或疾病及损伤而消失。研究人员认为早产儿其肾仍在发育,其尿液是高度有效的干/祖细胞的无创性来源。

为了检验这一假设,研究人员收集了31–36周胎龄早产儿出生后1天的新鲜尿液。使用单细胞RT-PCR技术分析基因的表达,并使用流式细胞仪和免疫荧光法分析蛋白的表达。

结果发现,新生儿的干/祖细胞表达了的肾祖细胞的标记物,同时也表达了间质祖细胞的标志物。此外,这些细胞呈现出骨髓间充质干细胞的特点,并可保护肾小管细胞对抗顺铂诱导的细胞凋亡。新生儿干/祖细胞分化而来的足细胞显示足细胞特异性基因、蛋白的表达上调,白蛋白的内吞作用以及钙离子内流的作用也加强。分化出的肾小管上皮细胞其特定的基因表达上调和P-糖蛋白的活性也显著升高。

总而言之,该研究发现早产儿尿液是一种新型的无创性的肾前体细胞来源,可分化为成熟的肾细胞,并具有较高的肾损伤修复及再生的潜力。

NEJM:吸入布地奈德减少早产儿支气管肺发育不良事件

背景:在极度早产儿中,全身性糖皮质激素能减少支气管肺发育不良的发生率,但可能会影响大脑发育。吸入性糖皮质激素对极度早产儿的影响目前尚不清楚。 方法:研究人员随机选取了863名婴儿(胎龄,23周0天至27周6天)至早期(出生后24小时内),并将437名婴儿分配至接受吸入性布地奈德组中,419名婴儿分配至安慰剂组,直至不再需要氧气和正压支持或直到胎龄达到32周0天。主要结局是通过在36周胎龄时标准化

NEJM:早产儿早期接受全身性糖皮质激素,利弊皆有

全身性糖皮质激素减少了极度早产儿支气管肺发育不良的发生率,但它们可能会损害脑发育。吸入性糖皮质激素对这些婴儿结果的影响目前还不清楚。研究人员随机分配863名婴儿(胎龄,23周0天〜27周6天)接受早期(出生后24小时内)吸入布地奈德或安慰剂,直到他们不再需要的氧气和正压支持或直到他们达到32周0天的胎龄。主要的结果是死亡或支气管肺发育不良,通过标准化的氧饱和度监测方法在36周胎龄时进行证实。在43

JAMA Pediatr:预防早产儿慢性肺疾病——INSURE治疗似乎优于NCPAP治疗

重要性:目前用来预防早产儿慢性肺疾病(CLD)的两大主要措施仍存在争议: 无创持续气道正压通气(NCPAP)及气管插管表面活性剂拔管(INSURE)。因呼吸窘迫综合症早产儿常需要表面活性剂治疗。目标:探讨INSURE或NCPAP单独预防CLD,死亡,或两者的有效性。数据源:研究者检索了2015年1月2日以前MEDLINE,EMBASE,Cochrane对照试验注册以及护理与医疗健康文献累积索引数据
