Effect of paeoniflorin on neuronal autophagy and Notch expression in tethered spinal cord in rats.

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.
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
Introduction: The study aimed to investigate the role of paeoniflorin in regulating neuronal autophagy and explore its ameliorative effects on the NOTCH signaling pathway in rat tethered spinal cord syndrome (TCS). Material and methods: We conducted an experiment using 60 healthy male SD rats, randomly divided into six groups: Sham + Vehicle (saline) group; Sham + Paeoniflorin (PF) 25 mg/kg group; TCS + Vehicle group; TCS + PF 25 mg/kg group; TCS + PF 50 mg/kg group; TCS + PF 100 mg/kg group. We assessed neurological recovery by measuring Tarlov scores and Basso-Beattie-Bresnahan (BBB) scores at 1, 3, 7, 11, and 14 days after injecting PF. Additionally, we evaluated autophagic pathways, including LC3, Beclin1, and Notch protein expressions in rat spinal cord cells for each group. Results: Lower limb neurological scores decreased after surgery on the first postoperative day. As the PF concentration increased, the recovery of Tarlov and BBB scores in rats accelerated. The comparison between PF treatment groups with different concentrations revealed a concentration-dependent effect. In the treated group, LC3 and Beclin1 protein expression levels gradually decreased with increasing PF dose. Notch protein expression around spinal cord tissue significantly increased in the treated group of rats, while it was not significant in the control group (Sham, Sham + PF 25 mg/kg groups). Conclusions: The results demonstrate that paeoniflorin can inhibit neuronal autophagy-related proteins and suppress apoptosis in spinal cord tissue. This inhibition contributes to improving neurological function in rats with tethered cord syndrome through the combined actions of autophagy inhibition and Notch pathway activation.
