Electroacupuncture Modulates Microbial Phenylalanine Metabolism and Enhances the Intestinal Barrier Function to Alleviate Colitis in Mice.
Article in Journal of inflammation research, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled 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.
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: Electroacupuncture (EA) exerts beneficial effects on ulcerative colitis. However, its underlying mechanisms remain elusive. In this study, we investigated the impact of high and low-frequency EA at Zusanli (ST36) on the gut microbiota and metabolite profile in the dextran sulfate sodium (DSS)-induced colitis mouse model. Methods: Colitis was established using DSS, and daily electroacupuncture at ST36 with varying frequencies was administered. Changes in body weight and fecal characteristics were monitored. Pro-inflammatory cytokines were detected, and the core molecule of intestinal barrier function were analyzed. The composition of intestinal flora was analyzed using 16S sRNA sequencing, while the changes of metabolites in colon tissue were detected by Ultra-performance liquid chromatography-tandem mass spectrometry (UPLC/MS/MS). Results: Treatment with both high and low frequencies of EA at ST36 significantly ameliorated the symptoms of colitis, while also exerting systemic and local anti-inflammatory effect by downregulating the proinflammatory cytokines, iNOS and MPO. EA at ST36 enhanced the intestinal barrier by upregulating the expression of MUC2 and ZO-1. Furthermore, high-frequency EA at ST36 remarkably restored the gut microbial composition and diversity, as well as modulated the gut microbial metabolism of phenylalanine. Conclusion: Our results suggest that EA treatment may alleviate colitis by reducing colon damage through gut microbiota-phenylalanine metabolism, which provides insight into EA's underlying mechanisms in the treatment of colitis.
