Our results illustrate that the entering and escaping processes of biopolymer depend on its negative entropy, and entering process is more difficult than escaping process for biopolymer translocation. This tremendous difference between the two processes will offer a useful engineering hint for single macromolecule identification.展开更多

Patients were divided into ICU-AW group and non-ICU-AW group according to whether they developed ICU-AW, or categorized into EEN and parenteral nutrition(PN) groups according to nutritional support. ICU-AW was diagnosed using the Medical Research Council score. The primary outcome was the occurrence of ICU-AW.RESULTS: The significant factors associated with ICU-AW included age, sex, type of nutritional therapy, mechanical ventilation(MV), body mass index(BMI), blood urea nitrogen(BUN), and creatinine(Cr) levels(P<0.05). The PN group developed ICU-AW earlier than did the EEN group, with a significant difference observed(log-rank P<0.001). Among biomarkers for ICU-AW, the mean prealbumin(PAB)/C-reactive protein(CRP) ratio had the highest diagnostic accuracy(area under the curve [AUC] 0.928, 95% confidence interval [95% CI] 0.892–0.946), surpassing the mean Cr/BUN ratio(AUC 0.740, 95% CI 0.663–0.819) and mean transferrin levels(AUC 0.653, 95% CI 0.574–0.733).CONCLUSION: Independent risk factors for ICU-AW include female sex, advanced age, PN, MV, lower BMI, and elevated BUN and Cr levels. EEN may potentially delay ICU-AW onset, and the PAB/CRP ratio may be an effective diagnostic marker for this condition.展开更多

文摘Background Necrotic enteritis(NE)in broiler chickens leads to significant economic losses in poultry production.This study examined the inhibitory effects of usnic acid and tannic acid on coccidia,sporozoite,and Clostridium perfringens and assessed their influence on growth performance and intestinal health in NE-challenged broilers through in vitro and in vivo experiments.Methods The in vitro experiment included 5 treatment groups:the negative control(NC),2μmol/L diclazuril(DZ),30μmol/L usnic acid(UA),90μmol/L tannic acid(TA),and 15μmol/L usnic acid^(+)45μmol/L tannic acid(UTA)groups.The in vivo experiment involved 320 broilers divided into four groups:PC(NE-challenged),SA(500 mg/kg salinomycin premix^(+)NE-challenged),UA(300 mg/kg usnic acid^(+)NE-challenged),and UTA(300 mg/kg usnic acid^(+)500 mg/kg tannic acid^(+)NE-challenged)groups.Results In the in vitro study,the UA,TA,and UTA treatments significantly increased apoptosis in coccidian oocysts and sporozoites,lowered the mitochondrial membrane potential(P<0.05),and disrupted the oocyst structure compared with those in the NC group.UA and TA had inhibitory effects on C.perfringens,with the strongest inhibition observed in the UTA group.The in vivo results demonstrated that the SA group presented significantly improved growth performance on d 13,21,and 28(P<0.05),whereas the UA and UTA groups presented improvements on d 13 and 21(P<0.05).The SA,UA,and UTA treatments reduced the intestinal lesion scores by d 28 and the fecal coccidian oocyst counts from d 19 to 21(P<0.05).Compared with the PC group,the UA and UTA groups presented lower intestinal sIgA levels and CD8^(+)cell percentages(P<0.05),with a trend toward a reduced CD3^(+)cell percentage(P=0.069).The SA,UA,and UTA treatments significantly reduced the serum diamine oxidase activity,crypt depth,and plateletderived growth factor levels in the intestinal mucosa while increasing the villus height to crypt depth ratio and number of goblet cells(P<0.05).The UTA treatment also significantly increased the acetate and butyrate concentrations in the cecum(P<0.05).With respect to the gut microbiota,significant changes inβdiversity in the ileum and cecum were observed in the SA,UA,and UTA groups,indicating that the microbial community compositions differed among the groups.Romboutsia dominated the SA group,Bacillales dominated the UA group,and Lactobacillales and Lachnospirales dominated the UTA group in the ileal microbiota.In the cecal microbiota,Lactobacillus,Butyricicoccus,and Blautia abundances were significantly elevated in the UTA group(P<0.05).Conclusion Usnic acid and tannic acid induce apoptosis in coccidia and sporozoites by lowering the mitochondrial membrane potential.Both usnic acid alone and in combination with tannic acid alleviate NE-induced adverse effects in broilers by modulating intestinal immunity,altering the microbial composition,and improving intestinal barrier function.Compared with usnic acid alone,the combination of usnic acid and tannic acid had superior effects,providing a promising basis for the development of effective feed additive combinations.

文摘Short-chain fatty acids,metabolites produced by the fermentation of dietary fiber by gut microbiota,have garnered significant attention due to their correlation with neurodegenerative diseases,particularly Parkinson’s disease.In this review,we summarize the changes in short-chain fatty acid levels and the abundance of short-chain fatty acid-producing bacteria in various samples from patients with Parkinson’s disease,highlighting the critical role of gut homeostasis imbalance in the pathogenesis and progression of the disease.Focusing on the nervous system,we discuss the molecular mechanisms by which short-chain fatty acids influence the homeostasis of both the enteric nervous system and the central nervous system.We identify key processes,including the activation of G protein-coupled receptors and the inhibition of histone deacetylases by short-chain fatty acids.Importantly,structural or functional disruptions in the enteric nervous system mediated by these fatty acids may lead to abnormalα-synuclein expression and gastrointestinal dysmotility,which could serve as an initiating event in Parkinson’s disease.Furthermore,we propose that short-chain fatty acids help establish communication between the enteric nervous system and the central nervous system via the vagal nerve,immune circulation,and endocrine signaling.This communication may shed light on their potential role in the transmission ofα-synuclein from the gut to the brain.Finally,we elucidate novel treatment strategies for Parkinson’s disease that target short-chain fatty acids and examine the challenges associated with translating short-chain fatty acid-based therapies into clinical practice.In conclusion,this review emphasizes the pivotal role of short-chain fatty acids in regulating gut-brain axis integrity and their significance in the pathogenesis of Parkinson’s disease from the perspective of the nervous system.Moreover,it highlights the potential value of short-chain fatty acids in early intervention for Parkinson’s disease.Future research into the molecular mechanisms of short-chain fatty acids and their synergistic interactions with other gut metabolites is likely to advance the clinical translation of innovative short-chain fatty acid-based therapies for Parkinson’s disease.
文摘Critically ill patients have a variety of complex pathologies and are in a multifarious state of catabolism supplanted by external and internal factors.Early enteral nutrition(EEN)is defined as the initiation of enteral feeding within 24-48 hours of hospitalization.Previous studies show the benefits of EEN include supporting the healing process through preservation of the gut mucosa,modulation of the immune response,and suppression of inflammation.However,recent studies suggest the advantages of EEN may not be as robust as previously believed.This review aims to discuss the outcomes of EEN when used in different critical care settings while managing complex disease states such as burns,sepsis,pancreatitis,and upper gastrointestinal bleeding.Evidence indicates that EEN has a positive impact on patient outcomes,hospital costs,length of intensive care unit stay,and preventing complications.

文摘Objective:Diabetes-induced gastrointestinal(GI)motility disorders are increasingly prevalent.Damage to the enteric nervous system(ENS),composed primarily of enteric neurons and glial cells,is an essential mechanism involved in these disorders.Although electroacupuncture(EA)has shown the potential to mitigate enteric neuronal loss,its mechanism is not fully understood.Additionally,the effects of EA on enteric glial cells have not been investigated.Enteric neural precursor cells(ENPCs)contribute to the structural and functional integrity of the ENS,yet whether EA enhances their differentiation into enteric neurons and glial cells remains unexplored.This study investigates whether EA promotes ENS repair through enhancing ENPC-derived neurogenesis and gliogenesis and elucidates the potential molecular mechanisms involved.Methods:Transgenic mice were used to trace Nestin+/nerve growth factor receptor(Ngfr)+ENPCs labeled with green fluorescent protein(GFP)in vivo.Mice were randomly divided into four groups:control,diabetes mellitus(DM),DM+sham EA,and DM+EA.The effects of EA on diabetic mice were evaluated by GI motility,ENS structure,and ENPC differentiation.Glial cell line-derived neurotrophic factor(GDNF)/Ret signaling was detected to clarify the underlying molecular mechanisms.Results:EA alleviated diabetes-induced GI motility disorders,as indicated by reduced whole gut transit time,shortened colonic bead expulsion time,and enhanced smooth muscle contractility.Furthermore,EA attenuated diabetes-induced losses of enteric neurons and glial cells,thereby restoring ENS integrity.Notably,EA reversed the diabetes-induced decrease in ENPCs and significantly increased the absolute number and the proportion of ENPC-derived enteric neurons.However,immunofluorescence analyses revealed no colocalization between EA-induced glial fibrillary acidic protein+glial cells and GFPlabeled ENPCs.Mechanistically,GDNF/Ret signaling was elevated in intestinal tissues and upregulated in ENPCs in EA-treated diabetic mice.Conclusion:EA facilitates ENS repair by promoting Nestin+/Ngfr+ENPC differentiation into enteric neurons via upregulation of GDNF/Ret signaling,and driving enteric gliogenesis from non-Nestin+/Ngfr+ENPCs.These findings highlight EA's role in ameliorating diabetes-induced GI dysmotility through ENPC-derived ENS restoration.
