Yuquan Pill (YQP) is a traditional Chinese medicine (TCM) for the treatment of type 2 diabetes (T2DM) in China for many years, and has a beneficial clinical effect. In this study, the antidiabetic mechanism of YQP was investigated for the first time from the perspective of metabolomics and intestinal microbiota. After 28 days of high-fat feeding, rats were injected intraperitoneally with streptozotocin (STZ, 35 mg/kg) followed by a single oral administration of YQP 2.16 g/kg and metformin 200 mg/kg for 5 weeks. The results showed that YQP was effectively improved insulin resistance and alleviated hyperglycemia and hyperlipidemia associated with T2DM. YQP was found to regulate metabolism and gut microbiota in T2DM rats using untargeted metabolomics and gut microbiota integration. Forty-one metabolites and five metabolic pathways were identified, including Ascorbate and aldarate metabolism, Nicotinate and nicotinamide metabolism, Galactose metabolism, Pentose phosphate pathway and Tyrosine metabolism. YQP can regulate T2DM-induced dysbacteriosis by modulating the abundance of Firmicutes, Bacteroidetes, Ruminococcus, Lactobacillus. The restorative effects of YQP in rats with T2DM have been confirmed and provide a scientific basis for the clinical treatment of diabetic patients.

The intestine features a two-front nutrient supply environment, comprising an enteral side enriched with microbial and dietary metabolites and a serosal side supplied by systemic nutrients, collectively supporting intestinal and systemic homeostasis, but there is currently no optimal approach for extracting and assessing the local intestinal microenvironment. Here, we present a protocol for constructing a nutrient supply model in mice and extracting gut interstitial fluid (GIF) via centrifugation. This model and the extracted GIF are suitable for downstream analyses.

2-Amino-3-methylimidazole [4,5-] quinoline (IQ) is a kind of heterocyclic amine (HCAs) with high carcinogenicity in hot processed meat. Rutin (Ru) is a flavonoid compound with anti-inflammatory and antioxidant properties. However, whether Ru is scatheless under IQ-stimulated potential unhealthy conditions, especially liver function, in vivo, is unknown.

Background/objectives: Autism spectrum disorder (ASD) is characterized by impaired social interaction and repetitive stereotyped behavior. Effective interventions for the core autistic symptoms are currently limited.
Methods: This study employed a valproic acid (VPA)-induced mouse model of ASD to assess the preventative effects of L-proline supplementation on ASD-like behaviors.

Background/objectives: Chronic gut dysbiosis due to a high-fat diet (HFD) instigates cardiac remodeling and heart failure with preserved ejection fraction (HFpEF), in particular, kidney/volume-dependent HFpEF. Studies report that although mitochondrial ATP citrate lyase (ACLY) supports cardiac function, it decreases more in human HFpEF than HFrEF. Interestingly, ACLY synthesizes lipids and creates hyperlipidemia.

Background/objectives: Ulcerative colitis (UC) is a chronic and easily recurrent inflammatory bowel disease. The gut microbiota and plasma metabolites play pivotal roles in the development and progression of UC. Therefore, therapeutic strategies targeting the intestinal flora or plasma metabolites offer promising avenues for the treatment of UC.
