Aconitum coreanum and processed products on its base prevent stroke via the PI3K/Akt and KEAP1/NRF2 in the in vivo study.

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
Aconitum coreanum (A. coreanum), a traditional Chinese medicine, has been proved to treat ischemic stroke (IS). However, the mechanisms of A. coreanum's anti-stroke is currently unknown. This study aimed to uncover the effect and mechanisms of A. coreanum. And study raw Aconitum coreanum (RA) and steamed Aconitum coreanum (SA) and Aconitum coreanum processed with ginger and Alumen (GA) on the mechanism of the pharmacological action of treating IS. Determining whether the efficacy is affected after processing. The right unilateral ligation of the carotid artery of gerbils was used to mimic IS. The neurological function score, infarct volume, oxidative stress level and inflammatory factor expression were measured in gerbils after IS. Western blot and immunofluorescence analyses were conducted to evaluate the expression of related proteins. Metabolomic analyzes IS-related metabolic pathways in urinary metabolites. RA, SA and GA significantly improved the infarct volume and behavioral score of IS gerbils, increased the expression of brain tissue superoxide dismutase (SOD), glutathione (GSH), nitric oxide (NO) and decreased the content of malondialdehyde (MDA), interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α). Western blot and immunofluorescence analysis results showed that RA, SA and GA significantly increased the expression of P-Akt, PI3K, HO-1 and KEAP1. Metabolomic studies identified 112 differential metabolites, including L-Proline, Riboflavin, Leukotriene D4, and 7-Methylxanthine, as potential biomarkers of stroke, involving 14 metabolic pathways including riboflavin metabolism, pyrimidine metabolism, and purine metabolism. Our findings indicated that A. coreanum protected against cerebral ischemia injury probably via the PI3K/Akt and KEAP1/NRF2 pathway. A. coreanum before and after processing both had a protective effect against IS brain injury in gerbils. The A. coreanum efficacy was not reduced after processing. Even compared to RA, SA had better efficacy.
