Acupuncture attenuates experimental autoimmune thyroiditis by modulating intestinal microbiota and palmitic acid 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
Introduction: Autoimmune thyroiditis (AIT) is a common and chronic autoimmune disease. Recent evidence indicates that serum metabolites and dysbiosis of the intestinal microbiota are associated with AIT, with the underlying mechanism involving the apoptosis of thyroid follicular epithelial cells. Acupuncture, a traditional Chinese therapy, has demonstrated potential regulatory effects on various immune-related diseases. Clinical symptoms in AIT patients have shown improvement following acupuncture intervention. However, the mechanism underlying its therapeutic effects remain poorly understood. Methods: In this study, we investigated the mechanisms of acupuncture (Acu) treatment in rats with established experimental autoimmune thyroiditis (EAT) and evaluated the relationship between microbiota and serum metabolites after Acu treatment. After six weeks of acupuncture and Selenium yeast intervention (used as a positive control), enzyme-linked immunosorbent assay was used to employed to assess the expressions of serum thyroid function and inflammatory markers. Pathological changes in the thyroid gland were observed using hematoxylin-eosin staining and electron microscopy. Thyroid apoptosis was evaluated through TUNEL staining, immunohistochemistry and Western blot analysis. Additionally, changes in intestinal microbiota and serum metabolic profile were analyzed by 16S ribosomal RNA (16S rRNA) sequencing and LC-MS metabolomics, aiming to identify potential therapeutic targets for acupuncture intervention in AIT. Results: The results revealed that Acu could effectively improve thyroid dysfunction and histopathological changes in EAT rats. Following Acu treatment, the content of B-cell lymphoma-2 (Bcl-2) increased, while the levels of Bax and the proportion of cleaved caspase-3 in thyroid tissue decreased. This may be associated with the amelioration of intestinal microbiota dysbiosis and metabolic disorders in EAT rats. Acu mitigated EAT-induced metabolic disorders by regulating the metabolism of palmitoleic acid, and adjusted intestinal microbiota dysbiosis by increasing the abundance of Prevotella. Furthermore, the microbiota (Prevotella) and metabolites (Cyclohexanecarboxylic acid, Tetradecanedioic acid) may serve as co-targets for both Acu and Selenium yeast treatment in EAT. Discussion: Acu improves the apoptosis of thyroid follicular epithelial cells in rats in EAT model, and its mechanism may be related to intestinal microbiota and metabolism.
