    Abstract Poor stability and difficult uptake of natural polysaccharides have been the main problems in their application. The purpose of this study was to optimize the preparation conditions of Polygonatum cyrtonema Hua polysaccharides liposomes (PCPL) and to investigate the immune enhancement activity of PCPL in vitro and in vivo, with a view to discovering new ways of natural polysaccharide application. The optimal preparation conditions of PCPL were as follows: the adding amount of Tween 80 of 0.5 %, the ultrasound time of 2 min and the ultrasound times of once. Under these conditions, the entrapment efficiency, drug loading rate and particle size of PCPL were 38.033 %±0.050, 2.172 %±0.003 and 146 nm, which indicated that PCPL with small particle size could be prepared by the reverse-phase evaporation method. Furthermore, PCPL promoted proliferation, phagocytosis, and secretion of nitric oxide and related cytokines in RAW264.7 cells. Moreover, PCPL improved spleen and thymus indices, increased the number or proportion of red blood cells, platelets, and lymphocytes in the blood, and ameliorated spleen and thymus atrophy in immunosuppressed mice. This study provides a new idea for applying Polygonatum cyrtonema Hua polysaccharides (PCP) and references for studying other polysaccharides.

    Abstract Currently, it is acknowledged that gout is caused by uric acid (UA). However, some studies have revealed no correlation between gout and UA levels, and growing evidence suggests that 2,8-dihydroxyadenine (2,8-DHA), whose structural formula is similar to UA but is less soluble, may induce gout. Hence, we hypothesized that uroliths from hyperuricemia (HUA) patients, which is closely associated with gout, may contain 2,8-DHA. In this study, 2,8-DHA in uroliths and serum of HUA patients were determined using HPLC. Moreover, bioinformatics was used to investigate the pathogenic mechanisms of 2,8-DHA nephropathy. Subsequently, a mouse model of 2,8-DHA nephropathy established by the gavage administration of adenine, as well as a model of injured HK-2 cells induced by 2,8-DHA were used to explore the pathogenesis of 2,8-DHA nephropathy. Interestingly, 2,8-DHA could readily deposit in the cortex of the renal tubules, and was found in the majority of these HUA patients. Additionally, the differentially expressed genes between 2,8-DHA nephropathy mice and control mice were found to be involved in inflammatory reactions. Importantly, CCL2 and IL-1β genes had the maximum degree, closeness, and betweenness centrality scores. The expressions of CCL2 and IL-1β genes were significantly increased in the serum of 24 HUA patients with uroliths, indicating that they may be significant factors for 2,8-DHA nephropathy. Further analysis illustrated that oxidative damage and inflammation were the crucial processes of 2,8-DHA renal injury, and CCL2 and IL-1β genes were verified to be essential biomarkers for 2,8-DHA nephropathy. These findings revealed further insights into 2,8-DHA nephropathy, and provided new ideas for its diagnosis and treatment.

    Abstract In our aging society, dysphagia and malnutrition are growing concerns, necessitating intervention. Liquid nutrition support offers a practical solution for traditional dietary issues, but it raises a key issue: the potential for post-meal glucose spikes impacting efficacy. This study examined the effects of supplementation of Polygonatum cyrtonema Hua polysaccharide (PCP), konjac glucomannan (KGM) and their combination on acute phase postprandial glycemic response and long-term glucose metabolism in T2DM mice on a complete nutritional liquid diet. KGM was more effective in reducing postprandial glucose response, while PCP was more prominent in ameliorating long-term glucose metabolism. The KGM-PCP combination demonstrated superior outcomes in fasting blood glucose, insulin, and glucose homeostasis. PCP and KGM also influenced the composition and abundance of the gut microbiome, with the H-PCP group showing optimal performance. Moreover, the KGM-PCP combination improved body weight, lipid homeostasis, and liver health the most. PCP potentially regulates glycemia through metabolic pathways, while KGM improves glycemic metabolism by reducing postprandial glucose levels in response to viscous intestinal contents. This research identifies the structure, viscosity properties, and hypoglycemic effects of KGM and PCP in complete nutritional liquid diet fed T2DM mice, enabling their strategic utilization as hypoglycemic components in nutritional administration and glycemic regulation.

    Abstract Ulcerative colitis (UC) is one common chronic inflammatory bowel disease that causes severe side effects, and expensive treatment limits effective and sustained treatment of UC. Fructooligosaccharide was isolated from Polygonatum Cyrtonema Hua (PFOS) and exhibits anti-inflammatory effects. Therefore, we are curious whether PFOS could be used for the treatment of UC. PFOS was introduced via intragastric gavage to C57BL/6 J mice exposed to acute colitis induced by DSS. The results showed that doses of PFOS at 2 and 5 mg/kg/day alleviated the DSS-induced histopathological damage and improved intestinal barrier function. qPCR analysis revealed that PFOS exerted a significant downregulation of pro-inflammatory cytokines (TNF-α, IL-1β, and IL-6) and upregulation of antioxidant genes, including superoxide dismutase1 (SOD1), glutathion peroxidase2 (GPX2), and nuclear factor erythroid 2 related factor2 (Nrf2). Furthermore, PFOS suppressed the DSS-induced disruption of the mucosal barrier by downregulating MMP13. Moreover, using 16 S rRNA gene-based microbiota analysis, PFOS could selectively enhance the growth of probiotics, including Bifidobacterium, Alloprevofella, and Alistipes. Our findings indicated that PFOS attenuated DSS-induced colitis in mice, suggesting that PFOS might be used as an efficacious supplement for reducing inflammatory bowel disease.

    Abstract The pathogenic hyper-inflammatory response has been regarded as the major cause of the severity and death related to acute lung injury (ALI). Hua-ban decoction (HBD) is a classical prescription in traditional Chinese medicine (TCM). It has been extensively used to treat inflammatory diseases; however, its bioactive components and therapeutic mechanisms remain unclear. Here, we established a lipopolysaccharide (LPS)-induced ALI model that presents a hyperinflammatory process to explore the pharmaco-dynamic effect and underlying molecular mechanism of HBD on ALI. In vivo, we confirmed that in LPS-induced ALI mice, HBD improved pulmonary injury by via down-regulating the expression of proinflammatory cytokines, including IL-6, TNF-α, and macrophage infiltration, as well as macrophage M1 polarization. Moreover, in vitro experiments in LPS-stimulated macrophages demonstrated that the potential bioactive compounds of HBD inhibited the secretion of IL-6 and TNF-α. Mechanically, the data revealed that HBD treatment of LPS-induced ALI acted via NF-κB pathway, which regulated macrophage M1 polarization. Additionally, two major HBD compounds, i.e., quercetin and kaempferol, showed a high binding affinity with p65 and IkBα. In conclusion, the data obtained in this study demonstrated the therapeutic effects of HBD, which indicates the possibility for the development of HBD as a potential treatment for ALI.

    Abstract Qing-Jin-Hua-Tan-Decoction (QJHTD), a classic famous Chinese ancient prescription, has been used for treatment of pulmonary diseases since Ming Dynasty. A total of 22 prototype compounds of QJHTD absorbed into rat blood were chosen as candidates for the pharmacological network analysis and molecular docking. The targets from the intersection of compound target and ALI disease targets were used for GO and KEGG enrichment analyses. Molecular docking was adopted to further verify the interactions between 22 components and the top 20 targets with higher degree values in the component-target-pathway network.

    Abstract Focal segmental glomerulosclerosis (FSGS) is a common clinical condition with manifestations of nephrotic syndrome and fibrosis of the glomeruli and interstitium. Yi-Shen-Hua-Shi (YSHS) granule has been shown to have a good effect in alleviating nephrotic syndrome (NS) in clinical and in animal models of FSGS, but whether it can alleviate renal fibrosis in FSGS and its mechanism and targets are not clear. In this study, we explored the anti-fibrotic effect and the targets of the YSHS granule in an adriamycin (ADR)-induced FSGS model and found that the YSHS granule significantly improved the renal function of ADR-induced FSGS model mice and also significantly reduced the deposition of collagen fibers and the expression of mesenchymal cell markers FN, vimentin, and α-SMA in the glomeruli of ADR-induced FSGS mice, suggesting that the YSHS granule inhibited the fibrosis of sclerotic glomeruli. Subsequently, a network pharmacology-based approach was used to identify the potential targets of the YSHS granule for the alleviation of glomerulosclerosis in FSGS, and the results showed that the YSHS granule down-regulated the expressions of BMP2, GSTA1, GATS3, BST1, and S100A9 and up-regulated the expressions of TTR and GATM in ADR-induced FSGS model mice. We also proved that the YSHS granule inhibited the fibrosis in the glomeruli of ADR-induced FSGS model mice through the suppression of the BMP2/Smad signaling pathway.

    Abstract Seasonal polyphenism is a phenomenon where two or more phenotypes are produced from a single genotype in different seasons. This phenomenon, a special type of phenotypic plasticity, is one of the major reasons for the success of insects and is also one of the primary sources of synonymy generations in insect taxonomy. Two nominal scorpionflies, Panorpa liui Hua, 1997 and Panorpa jilinensis Zhou, 2000 from the northeastern region of China, are very similar in morphology except for body coloration. However, whether they are conspecific or distinct species remains to be resolved. Here, we investigated these two nominal species through integrative taxonomy, including morphological variation analyses, geometric morphometrics of wing size and shape variations, genetic diversity, phylogenetic analyses based on two mitochondrial (COI and COII) and one nuclear (28S rRNA) gene fragments, and biological rearing. The results show that P. liui Hua, 1997 is a bivoltine species of seasonal polyphenism in the lowland plain, exhibiting a black morph in the spring and a yellow morph in the summer. Panorpa jilinensis Zhou, 2000 syn. nov. is considered as a junior synonym of P. liui Hua, 1997. The value of integrative taxonomy for species delimitation is discussed.
