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

Vascular dementia (VD) is one of the most common types of dementia, however, the intrinsic mechanism is unclear and there is still lack of effective medications. In this study, the VD rats exhibit a progressive cognitive impairment, as well as a time-related increasing in hippocampal neural stem cells (H-NSCs) senescence, lost and neurogenesis decline. Then, embryonic stem cell-derived small extracellular vesicles (ESC-sEVs) are intravenously injected into VD rats. ESC-sEVs treatment significantly alleviates H-NSCs senescence, recovers compromised proliferation and neuron differentiation capacity, and reverses cognitive impairment. By microarray analysis and RT-qPCR it is identified that several miRNAs including miR-17-5p, miR-18a-5p, miR-21-5p, miR-29a-3p, and let-7a-5p, that can inhibit mTORC1 activation, exist in ESC-sEVs. ESC-sEVs rejuvenate H-NSCs senescence partly by transferring these miRNAs to inhibit mTORC1 activation, promote transcription factor EB (TFEB) nuclear translocation and lysosome resumption. Taken together, these data indicate that H-NSCs senescence cause cell depletion, neurogenesis reduction, and cognitive impairment in VD. ESC-sEVs treatment ameliorates H-NSCs senescence by inhibiting mTORC1 activation, and promoting TFEB nuclear translocation and lysosome resumption, thereby reversing senescence-related neurogenesis dysfunction and cognitive impairment in VD. The application of ESC-sEVs may be a novel cell-free therapeutic tool for patients with VD, as well as other aging-related diseases.
