Abstract
Shenling Baizhu Powder (SLBZP), a traditional Chinese medicine (TCM) prescription renowned for its efficacy, is specifically recognized for its therapeutic effects in managing diarrhea associated with spleen qi deficiency. Our previous research has demonstrated that a lard diet in a fatigued state induced diarrhea belonging to spleen qi deficiency in TCM. Through a comprehensive investigation, we aimed to provide insights into the intricate relationship between SLBZP and the modulation of gut microbiota in alleviating symptoms associated with spleen qi deficiency-induced diarrhea. We induced diarrhea in mice by subjecting them to continuous standing on a multiple-platform apparatus while administering lard through intragastric administration for 14 days. Subsequently, we conducted gavage administration of SLBZP at a concentration of 0.637 g/ml for seven days. We observed a therapeutic effect of SLBZP on diarrhea induced by a lard diet in a fatigued state. SLBZP mitigated disorders in lipid metabolism and diminished hepatic oxidative responses. Additionally, SLBZP reversed gut microbiota dysbiosis of diarrheic mice and notably increased the production of short-chain fatty acids (SCFAs), primarily acetic acid, butyric acid, and valeric acid. Through correlation analysis, we additionally identified Lactobacillus reuteri and Lactobacillus intestinalis as potentially pivotal species associated with the therapeutic effects of SLBZP. We demonstrated that SLBZP exerts therapeutic effects on diarrhea caused by a lard diet in a fatigued state by repairing the intestinal mucosal barrier, improving lipid metabolism disorders, and regulating gut microbiota and metabolites SCFAs.

Wubuli A, Chai J, Liu H, Nijat D, Li J, Xia G, Cao Q, Zhang S, Huang W, Aipire A, Li J. In vivo pharmacokinetics of Glycyrrhiza uralensis polysaccharides. Front Pharmacol 2024; 15:1431221. [PMID: 39101144 PMCID: PMC11294697 DOI: 10.3389/fphar.2024.1431221] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/11/2024] [Accepted: 06/24/2024] [Indexed: 08/06/2024] Open
Abstract
Glycyrrhiza uralensis polysaccharides (GUPS) are widely applied in biomedicine and functional food due to their multiple pharmacological activities and low toxicity. Despite their widespread use, the in vivo metabolic profile of GUPS remains poorly understood. To address this gap, we developed a quantitative analysis method that involves labeling GUPS with visible fluorescein (5-DTAF) and near-infrared (NIR) fluorescein (Cy7), resulting in stable conjugates with substitution degrees of 0.81% for 5-DTAF and 0.39% for Cy7. The pharmacokinetic studies showed a biphasic elimination pattern in the blood concentration-time curve following both intravenous and oral administration, consistent with a two-compartment model. Using fluorescence quantification and NIR imaging, we observed that GUPS was distributed to various tissues, exhibiting higher concentrations particularly in liver, kidney and lung. Excretion studies indicated that feces were the major excretion pathway of GUPS after oral administration (60.98%), whereas urine was the main pathway after intravenous administration (31.16%). Notably, GUPS could be absorbed rapidly by gut (Tmax 1 ± 0.61 h) and showed a biological half-time t1/2 26.4 ± 7.72 h after oral administration. Furthermore, the Caco-2 cells uptake studies illustrated that macropinocytosis and clathrin-mediated endocytosis were participated in the transport of GUPS in intestine epithelium. This comprehensive analysis of the in vivo pharmacokinetics of GUPS not only enhances our understanding of its metabolic pathways but also establishes a foundational basis for its clinical application, optimizing its therapeutic potential and safety profile.

Research Progress on the Therapeutic Effect of Polysaccharides on Non-Alcoholic Fatty Liver Disease through the Regulation of the Gut–Liver Axis. Int J Mol Sci 2022; 23:ijms231911710. [PMID: 36233011 PMCID: PMC9570256 DOI: 10.3390/ijms231911710] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/31/2022] [Revised: 09/26/2022] [Accepted: 09/28/2022] [Indexed: 11/22/2022] Open
Abstract
Non-alcoholic fatty liver disease (NAFLD) is the most common chronic liver disease affecting global public health at present, which can induce cirrhosis and liver cancer in serious cases. However, NAFLD is a multifactorial disease, and there is still a lack of research on its mechanism and therapeutic strategy. With the development of the gut–liver axis theory, the association between the gut–liver axis and the pathogenesis of NAFLD has been gradually disclosed. Polysaccharides, as a kind of natural product, have the advantages of low toxicity, multi-target and multi-pathway action. It has been reported that polysaccharides can affect the gut–liver axis at multiple interrelated levels, such as maintaining the ecological balance of gut microbiota (GM), regulating the metabolites of GM and improving the intestinal barrier function, which thereby plays a protective role in NAFLD. These studies have great scientific significance in understanding NAFLD based on the gut–liver axis and developing safe and effective medical treatments. Herein, we reviewed the recent progress of polysaccharides in improving nonalcoholic fatty liver disease (NAFLD) through the gut–liver axis.
