Gestational diabetes mellitus (GDM) is a disease of glucose intolerance that first occurs during pregnancy. Accumulating evidence underlined a link between gut microbiota dysbiosis and GDM， and microbial metabolites represent a unique way to explore microbiota–host interactions. However， the associations between changes in the gut microbiota and microbial metabolites and immune homeostasis in the GDM pathogenesis remain largely unclear. In this prospective study， the characteristics of gut microbiota in both first trimester (T1) and second trimester (T2 ) were investigated in 46 GDM patients and 44 matched controls. We comprehensively profiled the microbial metabolites using non-targeted metabolomics and quantitatively targeted metabolomics， measurements of inflammatory cytokines and biomarkers of intestinal barrier function， and combined with correlation analysis in T2. Gut microbiota dybiosis was observed in GDM patients in both T1 and T2， and was characterised by the enrichment of multiple potentially harmful bacteria， such as UBA1819 and Erysipelatoclostridium. Besides， alterations in the microbiota were accompanied by a disturbance in tryptophan metabolism， mainly manifested as a shift towards the production of more kynurenine and less indole derivatives. Most importantly， correlation network analysis indicated that overgrowth of potential pathogens and tryptophan metabolism disorder were associated with inflammatory imbalance and disrupted epithelial barrier in GDM patients. Theses findings provide a greater understanding of the pathogenesis and new targets for microecological interventions by mediating tryptophan metabolism in GDM.

Acetaminophen (APAP) used as an antipyretic and analgesic agent can cause acute liver injury (AILI) under overdose. Sanghuangporous vaninii (S. vaninii) is a edible fungus with abundant metabolites exhibits excellent hepatoprotective activities， but the effect for AILI is not yet fully understood. In this study， the polyphenol-rich extract from S. vaninii (PSV) was prepared， with a total phenolic content of 75.72% and 34 compounds. The data of hepatoprotection indicated that PSV obviously alleviated the hepatocellular injury induced by APAP in vivo and in vitro. The protective mechanism of PSV against APAP-induced AILI might be attributed to the activating NRF2/GPX4 pathway. Based on network pharmacology analysis， the active components of PSV such as caffeic acid， osmundacetone and hispolone played a key role in hepatoprotection of PSV. Consequently， this study highlights the protection of PSV on AILI， which provides new insight into bioactivities of S. vaninii.

Cyanidin 3-O-β-galactoside from black chokeberry exerts neuroprotective effects in mice fed with high-fat/high-sugar diet through regulating glucose metabolism

Unhealthy diets are associated with various diseases that can disrupt brain energy metabolism， which significantly increased the risk of cognitive impairment and chronic neurodegenerative diseases. Early intervention with nutritional supplements may have long-lasting positive effects on diet-related glucose metabolism and potentially mediate the progression of neurodegeneration in middle-aged and elderly people. We previously reported that cyanidin 3-O-β-galactoside (Cy3Gal)， an anthocyanin from black chokeberry (Aronia melanocarpa (Michx.) Elliott)， alleviated cognitive impairment in aging mice through regulating brain energy metabolism. However， it remains unclear whether Cy3Gal can also exert beneficial effects in mice fed with a high-fat/high-sugar diet. Here we revealed that Cy3Gal treatment conserved the health of neurons and synapses， as well as cognitive function of mice. Furthermore， we observed that Cy3Gal effectively improved glucose uptake and metabolism of skeletal muscle by enhancing glycolysis both in vivo and in vitro models， which is essential for maintaining a stable glucose supply to the brain. Additionally， Cy3Gal significantly increased the levels of glucose-derived tricarboxylic acid cycle intermediates in the mice brain (P < 0.05)， and regulated the activities of mitochondrial respiratory chain complexes (P < 0.01). The positive influence on peripheral and brain bioenergetics explained how the Cy3Gal exerted neuroprotective effect. In conclusion， our study illustrated that early dietary intervention of Cy3Gal had significant advantages in terms of neuroprotection and cognition under the challenge of HFHS diet-induced glucose metabolism disorder.
