In our previous study, bile Arisaema was elucidated to have a significant anti-febrile effect, but the pharmacodynamic material basis of this effect remains uncertain. Herein, we found that the soluble polysaccharide fraction from bile Arisaema presents a remarkable antipyretic effect through balancing the gut microbiota and regulating metabolic profiling. Bile Arisaema polysaccharide (BAP) was characterized for its monosaccharide composition with arabinose, galactose, glucose, mannose and xylose (0.

Article Synopsis
  • Depression affects about 3.8% of the global population and current treatments, mainly medication and psychological support, often have limited effectiveness and high relapse rates.
  • Stem cell therapy is being researched as a potential new approach for treating depression, showing promise in triggering mechanisms like neurotrophic factor stimulation and immune function modulation; however, much of this research is still in its early stages.
  • While stem cell therapy could repair nerve damage and reduce neurotoxicity in depression, there are significant challenges to overcome before it can be widely used in clinical practice.

Article Synopsis
  • This study investigated the effects of two Chinese herbal medicines, Arisaematis Rhizoma and Arisaema Cum Bile, on the metabolism of healthy rats and those with cold or heat syndrome.
  • The researchers induced cold and heat syndrome in rat models and administered the herbal decoctions to observe changes in body weight, temperature, and key metabolic markers in the liver and heart.
  • Findings indicated that Arisaematis Rhizoma increased metabolic activity and body temperature (showing warm properties), while Arisaema Cum Bile reduced these levels (indicating cool properties), helping to improve the evaluation methods for traditional Chinese medicine.

Cattle bile (CBA) is a traditional medicine used for the treatment of febrile seizures (FS) for thousands of years in China. However, its application is greatly limited due to cost reasons, and pig bile (PBA) is the main commercial product instead. Additionally, the underlying mechanism of CBA for the treatment of FS still remains unknown.

As a new target protein for Alzheimer's disease (AD), the triggering receptor expressed on myeloid Cells 2 (TREM2) was expressed on the surface of microglia, which was shown to regulate neuroinflammation, be associated with a variety of neuropathologic, and regarded as a potential indicator for monitoring AD. In this study, a novel recognition system based on surface plasmon resonance (SPR) for the TREM2 target spot was established coupled with quadrupole time-of-flight tandem mass spectrometry (UPLC-MS), in order to screen the active ingredients targeting TREM2 from seeds. The results showed that four lignan-amides were discovered as candidate compounds by SPR biosensor-UPLC/MS recognition analysis.
