1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

The level of microRNA-9-5p (miRNA-9-5p) in brain tissues is significantly changed after traumatic brain injury (TBI). However, the effect of miRNA-9-5p for brain function in TBI has not been elucidated. In this study, a controlled cortical impact model was used to induce TBI in Sprague-Dawley rats, and an oxygen glucose deprivation model was used to mimic the pathological state in vitro. Brain microvascular endothelial cells (BMECs) and astrocytes were extracted from immature Sprague-Dawley rats and cocultured to reconstruct blood-brain barrier (BBB) in vitro. The results show that the level of miRNA-9-5p was significantly increased in brain tissues after TBI, and up-regulation of miRNA9-5p contributed to the recovery of neurological function. Up-regulation of miRNA-9-5p with miRNA agomir may significantly alleviate apoptosis, neuroinflammation, and BBB damage in rats after TBI. Moreover, a dual luciferase reporter assay confirmed that miRNA-9-5p is a post-transcriptional modulator of Ptch-1. In in vitro experiments, the results confirmed that up-regulation of miRNA-9-5p with miRNA mimic alleviates cellular apoptosis, inflammatory response, and BBB damage mainly by inhibiting Ptch-1. In addition, we found that the activation of Hedgehog pathway was accompanied by inhibition of NF-κB/MMP-9 pathway in the BMECs treated with miRNA-9-5p mimic. Taken together, these results indicate that up-regulation of miRNA-9-5p alleviates BBB damage and neuroinflammatory responses by activating the Hedgehog pathway and inhibiting NF-κB/MMP-9 pathway, which promotes the recovery of neurological function after TBI.
