Sea buckthorn (Hippophae rhamnoides L.) is a natural homologous substance of medicine and food. Polysaccharide， as one of its primary active components， has very superior biological activity and can be used as a dietary supplement for functional foods， with good commercial prospects. Although initial progress has been made in the study of sea buckthorn polysaccharides， related studies have been fragmented and lacked systematic and generalization. This manuscript presents a critical analysis and systematic summary of the extraction and purification methods， structural characterization and physicochemical properties， biological activity and potential mechanisms， and structure-activity relationships of sea buckthorn polysaccharides. Accumulating evidence has indicated that sea buckthorn polysaccharides， which were widely prepared by water extraction and column chromatography purifications， exhibited exhibit superior biological activities in vitro and in vivo， including antioxidant， immunomodulatory， anti-inflammatory， hepatorenal protective， antibacterial， antiviral， and prebiotic activities. After analysis， it was concluded that there is a correlation between the relevant activities of sea buckthorn polysaccharides and that the structure of sea buckthorn polysaccharides has a great influence on their biological activity. We reviewed the challenges and limitations of sea buckthorn polysaccharides， summarized the critical aspects， and provided suggestions for potential breakthroughs in the research and application of sea buckthorn polysaccharide.

The prevalence of iron deficiency anemia （IDA） remains high in infants， resulting in growth retardation， neurodevelopmental impairment， immunodeficiency and other irreversible injuries. Efficient and safe iron supplementation for infants has been the goal of recent research. This study aims to investigate the effect of encapsulated ferric pyrophosphate （FePP） on intestinal inflammation and gut microbiota in IDA suckling rats. Newborn Sprague Dawley rats were gavaged with low and high doses of FePP and FeSO4（2 and 10 mg Fe/kg BW， respectively） during postnatal days 2-14. Results showed that FePP supplementation was as effective as FeSO4in promoting growth， alleviating anemia and restoring body iron levels. Both low and high doses of FePP could significantly down-regulate the expression of pro-inflammatory cytokines in the colon to the level similar to that in the Ctrl group （P > 0.05）. However， the high dose of FeSO4did not show a down-regulation effect. Compared with the Ctrl group， IDA caused a disturbance of gut microbiota composition in suckling rats， and FePP could restore this dysbiosis. Besides， FePP was more beneficial than FeSO4in increasing the abundance of beneficial bacteria such as Bacteroides and Akkermansia. Spearman's correlation analysis showed a correlation between gut microbiota and biochemical indicators such as iron status， pro-inflammatory cytokine expression， and oxidative stress level. Overall， these findings suggested that FePP could effectively improve IDA， and is more effective than FeSO4in alleviating intestinal inflammation and regulating gut microbiota， which provides a basis for the application of new iron fortificant in infant formula.

Rotaviruses(RV) are a major cause of severe gastroenteritis, particularly in neonatal piglets. Despite the availability of effective vaccines, the development of antiviral therapies for RV remains an ongoing challenge. Retinoic acid(RA), a metabolite of vitamin A, has been shown to have anti-oxidative and antiviral properties. However, the mechanism by which RA exerts its intestinal-protective and antiviral effects on RV infection is not fully understood. The study investigates the effects of RA supplementation in Duroc × Landrace × Yorkshire(DLY) piglets challenged with RV. Thirty-six DLY piglets were assigned into six treatments, including a control group, RA treatment group with two concentration gradients(5and 15 mg/d), RV treatment group, and RV treatment group with the addition of different concentration gradients of RA(5 and 15 mg/d). Our study revealed that RV infection led to extensive intestinal architecture damage, which was mitigated by RA treatment at lower concentrations by increasing the villus height and villus height/crypt depth ratio(P research demonstrated that RA exerts a dual impact on the regulation of autophagy, both stimulating the initiation of autophagy and hindering the flow of autophagic flux. Through the modulation of autophagic flux, RA influence the progression of RV infection. These findings provide new insights into the regulation of redox hemostasis and autophagy by RA and its potential therapeutic application in RV infection.
