血清miR-101-3p在新生儿败血症中的诊断价值及机制研究

Abstract

Aim: This study aimed to evaluate the levels and functions of miR-101-3p in neonatal sepsis (NS). Materials & methods: Quantitative real-time PCR was conducted to investigate the expression of miR-101-3p and the receiver operating characteristic curve was applied to manifest its diagnostic effects. Results:miR-101-3p was increased in the NS patients and the dysregulation of miR-101-3p was associated with levels of procalcitonin, CRP, IL-8 and TNF-α. The combination of miR-101-3p and procalcitonin could function as a promising indicator in distinguishing NS patients. The silenced miR-101-3p reversed the increased levels of TNF-α and IL-8 caused by lipopolysaccharide in vitro. DUSP1 was identified as a direct target gene of miR-101-3p in NS. Conclusion: The abundance of miR-101-3p facilitated the inflammation in NS by targeting DUSP1.
