Taohe Chengqi Decoction Attenuates Cognitive Impairment in Experimental Sepsis-Associated Encephalopathy.
Article in CNS neuroscience & therapeutics, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
aimsSepsis-associated encephalopathy (SAE) is a clinical condition that is characterized by cognitive dysfunction induced by a systemic infection. This study was designed to assess the effect of the Taohe Chengqi decoction (THCQ) on SAE.
methodsTHCQ (in doses ranging from low to high) was administered to rats before the CLP procedure. An evaluation of the survival, cognitive dysfunction, damage to cortical or hippocampal tissues, and intestinal permeability of septic rats was undertaken. Rat intestinal microvascular endothelial cells were exposed to lipopolysaccharide and cocultured with choroid plexus endothelial cells.
resultsTHCQ alleviated symptoms of SAE and reduced cerebral and hippocampal damage in rats afflicted with sepsis. THCQ reduced intestinal permeability and prevented blood-cerebrospinal fluid barrier (BCSFB) disruption through systemic circulation. THCQ inhibited DUSP6 expression, and experimental overexpression of DUSP6 exacerbated intestinal barrier disruption and increased BCSFB permeability. The interaction between DUSP6 and FOXO1 mediated the dephosphorylation of FOXO1, increasing its nuclear translocation. Inhibition of FOXO1 reversed the effect of DUSP6 overexpression on SAE.
conclusionBy regulating the DUSP6/FOXO1 signaling, THCQ demonstrated protective effects on intestinal and BCSFB integrity, which were associated with improved cognitive outcomes in a rat model of SAE. These findings offer encouraging preclinical evidence with potential relevance.
