Muscarinic Receptor-Mediated Electroacupuncture Modulation of Reactive Enteric Glial Cells Ameliorates Postoperative Ileus.

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
Background: Emerging evidence highlights reactive enteric glial cells (EGCs) as pivotal players in the pathogenesis of postoperative ileus (POI). Recent studies have demonstrated that electroacupuncture (EA) Zusanli acupoint (ST 36) effectively alleviates POI. This study aims to investigate the underlying mechanisms of EA ST 36-mediated functional restoration of POI. Methods: A standardized intestinal manipulation (IM) procedure was conducted to establish the POI murine model. Mice were then treated with EA ST 36, and gastrointestinal (GI) motility function was measured after 24 hours. Immunofluorescence, Western blot, and hematoxylin-eosin staining were used to assess intestinal inflammation, the expression of glial fibrillary acidic protein (GFAP) and type 3 muscarinic acetylcholine receptors (m3AChRs). Vagus nerve activity was evaluated through plasma enzyme-linked immunosorbent assay combined with heart rate variability. Results: Compared to the Sham group, animals in the IM group demonstrated GI dysfunction characterized by delayed whole gut transit, prolonged colonic bead expulsion time, and reduced heart rate variability, which accompanied by decreased acetylcholine levels, elevated Chiu's scores, upregulated GFAP expression, and downregulated m3AChRs expression. EA ST 36 effectively mitigated these changes and enhanced c-Fos protein expression in the nucleus tractus solitarius. Fluorocitrate (a glial cell inhibitor) and carbachol (a cholinergic agonist) replicated the effects of EA ST 36, which was abolished by either pretreatment with J104129 (a specific m3AChR antagonist) or surgical vagotomy. Conclusion: The results suggest that EA ST 36 exerts its effects through vagally-mediated modulation of m3AChR signaling, which involves the reduction of the reactivity of EGCs and the improvement of GI dysfunction induced by IM.
