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

Hemorrhagic transformation (HT) is a major complication of reperfusion therapy after ischemic stroke, but its impact on Alzheimer disease (AD) progression remains unclear. In this study, we used an early-stage APP/PS1 mouse model and found that HT following transient middle cerebral artery occlusion(tMCAO) aggravated cognitive impairment and promoted AD-like pathological changes, which were markedly attenuated by Timosaponin B-II (TB-II) treatment. TB-II effectively alleviated HT following tMCAO(tMCAO/HT)-induced cognitive and recognition memory deficits in APP/PS1 mice and reduced hippocampal Aβ42 production. In vitro, TB-II pretreatment reversed oxygen-glucose deprivation/reoxygenation (OGD/R) and hemin-induced increases in Aβ42 production and apoptotic propensity, as well as decreases in mitochondrial membrane potential and cell viability in N2a/APPswe cells. Mechanistically, TB-II activated NRF2, which in turn indirectly modulating GSK-3β-mediated APP phosphorylation and negatively regulated BACE1 transcription through binding promoter binding, ultimately suppressing amyloidogenic processing. Together, our findings suggest that TB-II may serve as a potential therapeutic agent against HT-associated acceleration of AD-like pathology after ischemia-reperfusion.
