Non-invasive vagus nerve stimulation in anti-inflammatory therapy: mechanistic insights and future perspectives.

Non-invasive vagus nerve stimulation (VNS) represents a transformative approach for managing a broad spectrum of inflammatory and autoimmune conditions, including rheumatoid arthritis and inflammatory bowel disease. This comprehensive review delineates the mechanisms underlying VNS, emphasizing the cholinergic anti-inflammatory pathway, and explores interactions within the neuro-immune and vagus-gut axes based on both clinical outcomes and pre-clinical models. Clinical applications have confirmed the efficacy of VNS in managing specific autoimmune diseases, such as rheumatoid arthritis, and chronic inflammatory conditions like inflammatory bowel disease, showcasing the variability in stimulation parameters and patient responses.

Simultaneous determination of alizarin and rubimaillin in Rubia cordifolia by ultrasound-assisted ionic liquid-reversed phase liquid chromatography.

Four kinds of ionic liquids were adopted to analyze the content of rubimaillin and alizarin in Rubia cordifolia roots with ultrasonic-assisted extraction coupled with HPLC. The chromatographic column, Purospher star RP-C18 (4.6 mm x 250 mm, 5 microm), was used.
