The Tianma Anshen Dingxuan Formula Regulates Gut Microbiota and Metabolites in a Rat Model of Vertigo With Liver Yang Hyperactivity.
Introduction: Vertigo is a prevalent clinical disorder that significantly compromises the quality of life of a patient. Among the syndrome patterns recognized in traditional Chinese medicine (TCM), vertigo due to liver-yang hyperactivity (LYH) is the most common subtype. This study explored the underlying therapeutic mechanisms of Tianma Anshen Dingxuan formula (TADF) on vertigo induced by LYH through the analysis of gut microbiota and their metabolites.
Methods: A total of 30 Sprague-Dawley rats were assigned to control, LYH vertigo model, and TADF groups. The LYH vertigo model was established through intragastric administration of aconite decoction combined with unilateral labyrinthectomy. Behavioral changes and colonic histopathology were conducted. The concentrations of 5-hydroxytryptamine (5-HT), dopamine (DA), and norepinephrine (NE) in the rat hypothalamus were quantified using the enzyme-linked immunosorbent assay (ELISA). The gut microbiota and metabolites were analyzed using 16S rRNA gene sequencing and ultrahigh-performance liquid chromatography-mass spectrometry (UHPLC-MS). Spearman correlation analysis was performed to explore the relationships among the microbiota, metabolites, and behavioral indices.
Results: Treatment with TADF significantly improved behavioral indices (such as reduced head tilt, normalized reflexes) and colonic inflammation (lower histopathological scores, p < 0.01), whereas it significantly reduced the concentrations of 5-HT, DA, and NE in the rat hypothalamus (p < 0.05). Additionally, TADF modulated gut microbiota by upregulating both p_Patescibacteria and o_Oscillospirales while downregulating g_Bifidobacterium. Metabolomics identified 16 biomarkers (for instance, N-acetylneuraminate) enriched in pathways like tryptophan metabolism. Spearman analysis revealed correlations between microbiota (g_Ruminococcus), metabolites (chlorphenoxamine), and behavioral scores.
Conclusion: Collectively, this study is the first to demonstrate the therapeutic effect of TADF on vertigo-afflicted rats. TADF significantly improved the levels of microbiota-mediated metabolites by restoring the impaired gut microbiota.
期刊介绍：
Phytochemical Analysis is devoted to the publication of original articles concerning the development, improvement, validation and/or extension of application of analytical methodology in the plant sciences. The spectrum of coverage is broad, encompassing methods and techniques relevant to the detection (including bio-screening), extraction, separation, purification, identification and quantification of compounds in plant biochemistry, plant cellular and molecular biology, plant biotechnology, the food sciences, agriculture and horticulture. The Journal publishes papers describing significant novelty in the analysis of whole plants (including algae), plant cells, tissues and organs, plant-derived extracts and plant products (including those which have been partially or completely refined for use in the food, agrochemical, pharmaceutical and related industries). All forms of physical, chemical, biochemical, spectroscopic, radiometric, electrometric, chromatographic, metabolomic and chemometric investigations of plant products (monomeric species as well as polymeric molecules such as nucleic acids, proteins, lipids and carbohydrates) are included within the remit of the Journal. Papers dealing with novel methods relating to areas such as data handling/ data mining in plant sciences will also be welcomed.
