Acupuncture and moxibustion in irritable bowel syndrome: a mechanistic exploration from heart rate variability to cardiac metabolism.

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: Patients with irritable bowel syndrome (IBS) exhibit abnormal heart rate variability (HRV). While acupuncture and moxibustion have shown therapeutic potential in IBS, the optimal acupoint selection strategy remains to be elucidated, and its effects on HRV and cardiac metabolomics in IBS models are incompletely understood. This study therefore aimed to compare the efficacy of two distinct acupoint protocols, BB (biao-ben protocol) and CG (conventional protocol), in modulating HRV and cardiac metabolomic profiles in a rat model of IBS. Methods: This study established an IBS rat model using chronic and acute stress (CAS). Two acupoint protocols were employed for the intervention of acupuncture combined with moxibustion: the BB group, which adhered to the fundamental Chinese medicine principle of "treating both the root and the branch" by selecting Neiguan (PC6), Guanyuan (CV4), and Zusanli (ST36); and the CG group, which utilized the most frequently used acupoints in clinical practice, namely Tianshu (ST25), Zusanli (ST36), and Shangjuxu (ST37). Visceral pain thresholds were measured by abdominal withdrawal reflexes (AWR). HRV was assessed using the BL-420F biofunctional experimental system. ELISA quantified atrial natriuretic peptide (ANP) and brain natriuretic peptide (BNP) levels in tissues and serum. Cardiac tissue metabolites analyzed through widely-targeted metabolomics and pathway enrichment performed via KEGG database. Result: Both BB and CG acupoint combinations significantly alleviated visceral pain thresholds in IBS rats. The BB protocol demonstrated superior efficacy in improving HRV parameters and regulating ANP and BNP levels in both serum and cardiac tissue. Metabolomic results revealed elevated concentrations of adenosine diphosphate (ADP), kynurenine, and kynurenic acid in the model group compared to the control, indicating disruptions in cardiac energy metabolism and inflammation-driven aberrations in tryptophan metabolism in IBS rats. The BB group exhibited downregulation of these metabolites. Conclusion: The BB acupoint combination may improve heart rate variability via autonomic nervous regulation, leading to the amelioration of cardiac energy metabolism and inflammation-driven tryptophan metabolic disorders.
