Objevtive: To investigate the effects of Cyclocarya paliurus (C. paliurus) polysaccharides on the spleen injury of diabetic rats.
Methods: Animals were divided into 6 groups, including normal group, model group, control group, low-dose group of C. paliurus polysaccharides treatment, middle-dose group of C. paliurus polysaccharides treatment and high-dose group of C. paliurus polysaccharides treatment. Histological analysis of spleen was analyzed using hematoxilin and eosin. Levels of biological parameters and anti-oxidative enzymes were determined by spectrophotometry. Interleukin-7 (IL-7) and IL-10 were measured by enzyme-linked immunosorbent assay.
Results: Compared with that of model group, superoxide dismutase, catalase, glutathione peroxidase, glutathione reductase level increased 78.63% (P < 0.05), 51.76% (P < 0.05), 2.95 times (P < 0.01) and 41.11% (P < 0.05) in the high-dose group of C. paliurus polysaccharides treatment, respectively. IL-7 and IL-10 increase 1.66 (P < 0.01) and 1.21 times (P < 0.01) in the high-dose group of C. paliurus polysaccharides treatment, respectively.
Conclusion: It is suggested that C. paliurus polysaccharides may play a protecting role for spleen injury of diabetic rats by enhancing the antioxidative ability and evaluating the immunity.

Article Synopsis
- The study focuses on "sweet tea," an herbal tea known for its unique nutritional benefits and flavor, but struggles to completely satisfy consumers' taste preferences due to its bittersweet profile.
- Researchers analyzed the growth period of tea leaves, examining the variation in compounds that contribute to sweet and bitter flavors using advanced metabolomics and molecular docking techniques.
- They identified 575 metabolites linked to taste and found six key compounds that have high sweetness and low bitterness, offering insights for improving the sensory quality of tea.

The biosynthesis and accumulation of secondary metabolites play a vital role in determining the quality of medicinal plants, with carbohydrate metabolism often influencing secondary metabolism. To understand the potential regulatory mechanism, exogenous sugars (sucrose, glucose/fructose) were applied to the leaves of Cyclocarya paliurus, a highly valued and multiple function tree species. The results showed that exogenous sugars enhanced the accumulation of soluble sugar and starch while increasing the enzyme activity related to carbohydrate metabolism.

In this study, a new component of polysaccharides (CPP20) was precipitated by the gradient ethanol method, and the protective effect of CPP20 on hypercholesterolemia mice was investigated. In vitro, CPP20 had the ability to bind bile salts and inhibit cholesterol micelle solubility, and it could effectively clear free radicals (DPPH•, •OH, and ABTS+). In vivo, CPP20 effectively alleviated hypercholesterolemia and liver damage in mice.

Article Synopsis
- Scientists studied a substance called SCP3 from a plant, Cyclocarya paliurus, to see how it helps protect the intestines from damage caused by something called oxidative stress.
- They found that SCP3 helps the intestines by boosting a protective enzyme and reducing harmful substances, which stops cells from dying.
- The research showed that two important pathways in the body, MAPK and PI3K/Akt, play a key role in how SCP3 protects the intestinal cells, suggesting it could be useful in health products and medicines.
