Bone loss caused by ageing has become one of the leading health risk factors worldwide.Wheat germ(WG)is consists of high amounts of bioactive peptides,polyunsaturated fatty acids,and dietary fibre.Currently,WG has been proven to possess strong antioxidant and anti-infl ammatory properties.We recently explored the beneficial effects and relevant mechanisms of a WG-rich diet(2.5%and 5%WG,m/m)on bone homeostasis in aged rats.Our results showed that 5%WG supplementation for 12 months effectively attenuated ageing-induced microstructural damage and differentiation activity changes in the femur.The 5%WG supplementation also signifi cantly increased the levels of total antioxidant capacity(T-AOC),glutathione peroxidase(GSH-Px)(P<0.01),and superoxide dismutase(SOD)(P<0.05),and decreased infl ammatory cytokine levels(tumor necrosis factor-α(TNF-α)and interleukin-6(IL-6))(P<0.01).Furthermore,the WG-rich diet reshaped the composition of the gut microbiota,enhancing short-chain fatty acids(SCFAs)-producing microbes and reducing infl ammation-related microbes.In addition,metabolomics analysis showed that 5%WG supplementation improved plasma metabolites related to bone metabolism.Conclusively,our study purports long-term WG-rich diet may preserve bone homeostasis by regulating gut microbiota and plasma metabolites in aged rats. 展开更多

Ulcerative colitis(UC)is a chronic systematic inflammation disorder with increasing incidence,unknown pathogenesis,limited drug treatment,and abundant medical expenses.Dietary intake,as a daily indispensable environment factor,is closely related to UC pathogenesis and prevention.The underlying interactions between dietary intake and UC progression are implicated with the modulation of gut microbiome as well as microbial metabolites,suggesting the complex and systematic characteristics of UC.However,the triangular relationships with dietary intake,gut microbiota homeostasis,and UC have not been well summarized so far.Here we review the recent studies of dietary intake on the regulation of gut microbiome homeostasis as well as modulation of UC progression.These findings suggest that varieties in dietary patterns result in the production of diverse microbial fermentation metabolites,which contribute to gut microbiome homeostasis through multiple manipulations including immune modulation,inftammation restriction as well as epithelial barrier maintenance,thus finally determine the fate of UC progression and give implications for functional food development for prevention and treatment of UC patients. 展开更多

Theasinensin A(TSA),a dimer of epigallocatechin gallate,has been preliminarily demonstrated to have hypoglycemia and anti-inflammatory effects.However,little information is available on its potential mechanisms of anti-diabetes.Therefore,the present study aimed to investigate the influence of TSA on glucose and lipid metabolism and gut microbiota in high-fat-diet/streptozotocin-induced diabetic mice.As result,TSA improved polydipsia,polyphagia and impaired glucose tolerance of diabetic mice,declined the fasting blood glucose and hepatic triglyceride level,and enhanced the expression at mRNA level of insulin receptor substrate,phosphoinositide 3-kinase,protein kinase B and glucagon-like peptide 1 receptor(GLP-1R)in the diabetic liver.Moreover,TSA could restore the disorder of gut microbiota of diabetic mice.High-dose(100 mg/kg)TSA showed better benefi cial effects from the blood biochemical parameters,hepatic function and gut microbiota.In general,high-dose TSA significantly modulated gut microbiota by increasing the relative abundance of Akkermansia and decreasing the relative abundances of Acetatifactor,Anaerotruncus,Pseudofl avonifactor,Oscillibacter and Clostridium clusters.The results indicated that TSA could exert an anti-diabetes effect in diabetic mice through restoring glucose homeostasis,declining hepatic steatosis,activating insulin and GLP-1 signaling pathways,and ameliorating gut microbiota dysbiosis. 展开更多

Sepsis,a highly life-threatening organ dysfunction caused by uncontrollable immune responses to infection,is a leading contributor to mortality in intensive care units.Sepsis-related deaths have been reported to account for 19.7%of all global deaths.However,no effective and specific therapeutic for clinical sepsis management is available due to the complex pathogenesis.Concurrently eliminating infections and restoring immune homeostasis are regarded as the core strategies to manage sepsis.Sophisticated nanoplatforms guided by supramolecular and medicinal chemistry,targeting infection and/or imbalanced immune responses,have emerged as potent tools to combat sepsis by supporting more accurate diagnosis and precision treatment.Nanoplatforms can overcome the barriers faced by clinical strategies,including delayed diagnosis,drug resistance and incapacity to manage immune disorders.Here,we present a comprehensive review highlighting the pathogenetic characteristics of sepsis and future therapeutic concepts,summarizing the progress of these well-designed nanoplatforms in sepsis management and discussing the ongoing challenges and perspectives regarding future potential therapies.Based on these state-of-the-art studies,this review will advance multidisciplinary collaboration and drive clinical translation to remedy sepsis. 展开更多

Brain energy homeostasis is a vital physiological function in maintaining a balanced internal metabolic environment.The impairment of energy homeostasis is recognized as a key pathophysiological basis for brain metabolic disorders and related neurodegenerative diseases.Dendrobium species(‘Shihu’in Chinese)such as D.officinale,D.huoshanense,D.nobile,D.chrysanthum,D.loddigesii,D.moniliforme,D.gratiosissimum,D.candidum and D.caulis are widely used as traditional Chinese medicines/nutraceuticals to control and treat neurodegenerative disorders.These dietary herbs and their derived compounds possess a variety of biological properties,such as suppression of oxidative stress and neuroinflammation,regulation of energy homeostasis mainly through improving brain mitochondria function,insulin signaling and lipid metabolism.Furthermore,they reduce neurotoxicity,alleviate brain injury and neuropathy,and prevent neurodegenerative conditions including stroke,Alzheimer’s disease,Parkinson’s disease,and Huntington’s disease in humans and/or rodents.Moreover,the nutraceuticals from Dendrobium species promote gut health and aid digestion,which appear to be associated with beneficial effects on brain energy homeostasis.Based on the above-mentioned health benefits associated with Dendrobium species,this work reviews their nutraceutical role in neurodegenerative disorders and further suggests the need to elucidate mechanisms of the underlying molecular actions. 展开更多

Homeostasis is the adaptability of a species to a changing environment.However,the ecological stoichiometric homeostasis of Robinia pseudoacacia L.in diff erent climatic regions is poorly understood but could provide insights into its adaptability in the loess hilly region.This study sampled 20 year-old R.pseudoacacia plantations at 10 sites along a north–south transect on the Loess Plateau.Variations in the ecological stoichiometric characteristics of leaf and soil carbon,nitrogen,and phosphorus were analysed and homeostatic characteristics of leaf ecological stoichiometric parameters in diff erent climates were identifi ed.Factors aff ecting leaf stoichiometry were assessed.The results show that R.pseudoacacia leaves were rich in nitrogen and defi cient in phosphorous during tree growth and development.Nitrogen and phosphorous levels in the soils of the loess region were lower than the average in soils in the rest of China.All ecological stoichiometric parameters of R.pseudoacacia leaves in two diff erent climates were considered“strictly homeostasis”.Precipitation,available phosphorus,and soil C:P were the main factors aff ecting the variation of C:N:P stoichiometry of R.pseudoacacia leaves.R.pseudoacacia in the loess hilly region has strong ecologically homeostatic characteristics and suggests that it is well-adapted to the area. 展开更多

Hemophagocytic lymphohistiocytosis (HLH) is an aggressive and often fatal overactivation of the immune system. It is characterized by inappropriate and dysregulated activation of natural killer (NK) cells, CD8^(+)cytotoxic T cells, and macrophages. Ineffective interactions between NK cells, CD8^(+)T cells, and their pathogenic targets lead to massive cytokine accumulation and widespread macrophage activation. Resultant hemophagocytosis and excessive organdamaging infl ammation subsequently occur.HLH may be triggered by genetic or sporadic disorders,as well as specific events that alter immune homeostasis.These events include inflammatory or infectious disease processes and malignancy. 展开更多
