ObjectiveTo investigate the effect of schisanlactone E in ameliorating neuroinflammation and synaptic injury in APP/PS1 mice and to elucidate whether its mechanism is related to the regulation of helper T cell 17 （Th17）/regulatory T cell （Treg） immune balance. MethodsAPP/PS1 transgenic mice were assigned into model， low- and high-dose （2 mg·kg^-1·d^-1 and 4 mg·kg^-1·d^-1， respectively） schisanlactone E， and donepezil （1 mg·kg^-1·d^-1） groups. C57BL/6J mice were used as the control group. Each group received the corresponding drug by gavage for 30 days. Learning and memory abilities were assessed by the Morris water maze and novel object recognition tests. The percentages of Th17 and Treg cells in the peripheral blood were analyzed by flow cytometry. The mRNA levels of retinoid-related orphan receptor γt （RORγt）， interleukin （IL）-17A， forkhead box protein 3 （FoxP3）， and IL-4 in the hippocampus were determined by Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR）. The synaptic ultrastructure in the hippocampus was observed by transmission electron microscopy. The protein levels of synapsin Ⅰ and postsynaptic density protein 95 （PSD95） in the hippocampus were measured by Western blot. Aβ aggregation and microglial activation in the hippocampus were observed by immunofluorescence staining. The mRNA levels of tumor necrosis factor （TNF）-α， IL-6， and IL-1β in the hippocampus were determined by Real-time PCR.

ObjectiveTo observe the effect of aspirin curcumin ester （CA） on the activation and glucose metabolism reprogramming of the mouse microglia （BV2） model of inflammation induced by high glucose/β-amyloid （Aβ）_1-42， and to explore the potential mechanism of CA in reducing neuroinflammatory response in the brain. MethodsThe BV2 activation model was constructed by high glucose combined with Aβ_1-42 oligomers. BV2 cells were treated with Aβ_1-42 oligomers （10 μmol·L^-1） in a high glucose （50 mmol·L^-1） environment and allocated into normal， high glucose， Aβ， and high glucose + Aβ groups. The cell morphology of each group was observed under a bright field. Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） was adopted to assess the mRNA levels of inflammatory factors including tumor necrosis factor-α （TNF-α）， interleukin-6 （IL-6）， and interleukin-1β （IL-1β） as well as glycolysis-related glucose transporter type 1 （GLUT1）， hexokinase 2 （HK2）， phospofructokinase-2/fructose-2，6-bisphosphatase 3 （PFKFB3）， and pyruvate kinase M2 （PKM2）. To reveal the effects of CA on inflammatory response and glucose metabolism in BV2 cells exposed to high glucose/Aβ_1-42， this study established the BV2 cell model of inflammatory activation by high glucose and Aβ_1-42 oligomer intervention. The cells were allocated into normal， model （50 mmol·L^-1 glucose + 10 μmol·L^-1 Aβ_1-42）， CA （10 μmol·L^-1）， 2DG （0.2 mmol·L^-1）， and DADA （1 mmol·L^-1） groups. Cell counting kit-8 （CCK-8） was used to detect cell survival rate. The cell morphology of each group was observed under a bright field. The expression of inflammatory factors TNF-α， IL-6， and IL-1β and glycolysis-related key enzymes GLUT1， HK2， PFKFB3， and PKM2 at the mRNA level in each group was measured by real-time PCR. The protein levels of GLUT1， HK2， PFKFB3， and PKM2 were determined by Western blot. The glycolysis rate in each group was measured by seahorse. LC-MS was employed to identify the glucose metabolism intermediates. The morphology of mitochondria in cells was observed by electron microscopy. ResultsConstruction of the BV2 cell model： Compared with the normal group， the Aβ group and the high glucose + Aβ group showed more amoeboid-shaped cells and cell aggregation. The high glucose + Aβ group exhibited increased the mRNA levels of TNF-α， IL-1β， and IL-6 （P<0.05， P<0.01）， as well as those of key glycolytic enzymes GLUT1， HK2， PFKFB3， and PKM2 （P<0.01）. The Aβ group also showed significantly increased mRNA levels of PKM2 and PFKFB3 （P<0.01）. Effects of CA on the inflammatory response and glucose metabolism in BV2 cells exposed to high glucose/Aβ_1-42： Compared with the normal group， the model group exhibited amoeboid-shaped cells and cell aggregation， upregulated mRNA levels of TNF-α， IL-1β， IL-6， iNOS， GLUT1， HK2， PFKFB3， and PKM2 （P<0.01） and protein levels of GLUT1， HK2， and PFKFB3 （P<0.05， P<0.01）， an increased basal glycolysis rate （P<0.01）， a decreased compensatory glycolysis rate （P<0.01）， increased glycolytic intermediates and reduced TCA cycle intermediates. In addition， the mitochondria in the model group exhibited a decreased number （P<0.05）， impaired crista integrity （P<0.01）， an increased proportion of vacuolization （P<0.01）， and abnormal mitochondrial morphology. Compared with those in the model group， the number of amoeboid-shaped BV2 cells reduced in the CA and 2DG groups， while most BV2 cells in the DADA group became elongated spindle-shaped. All the three treatment groups showed downregulated mRNA levels of TNF-α， IL-1β， IL-6， GLUT1， HK2， PFKFB3， and PKM2 （P<0.05， P<0.01）， downregulated protein levels of GLUT1， HK2， and PFKFB3 （P<0.05， P<0.01）， and slow compensatory glycolysis and basal glycolysis （P<0.05， P<0.01）. Glycolytic intermediates were decreased and TCA cycle intermediates were increased in the CA and 2DG groups. Mitochondrial morphology largely returned to the normal level in all the three treatment groups， with an increase in mitochondrial number （P<0.05）， improved crista integrity （P<0.05， P<0.01）， and a decreased proportion of vacuolization （P<0.05）. ConclusionAβ_1-42 oligomers can activate BV2 cells and enhance glycolytic activity in the high glucose environment. CA can reduce the expression of inflammatory factors and inhibit the activation of BV2 cells by regulating the glucose metabolism reprogramming in BV2 cells.

MethodsGlycosides related to AD-associated neuroinflammation were screened through bibliometric analysis， and the potential targets of PF were predicted through network pharmacology and molecular docking. A rat model of AD was established by intraperitoneal injection of D-galactose （100 mg·kg^-1·d^-1）. Rats were assigned into a control group， a model group， a PF （200 mg·kg^-1） group， and a donepezil （0.5 mg·kg^-1·d^-1） group， and drugs were administered by gavage for 21 days. The learning and memory abilities were evaluated by the Morris water maze （MWM）. Hematoxylin-eosin （HE） staining and Nissl staining were performed to observe hippocampal neuronal morphology. The mRNA levels of inflammatory factors were determined by Real-time quantitative polymerase chain reaction （Real-time PCR）， and the protein levels of molecules in the JAK2/STAT3 signaling pathway were determined by Western blot. ResultsCompared with the control group， the model group showed prolonged escape latency and decreased platform crossings and time spent in the target quadrant （P<0.05， P<0.01）， accompanied by increased expression of interleukin-1β （IL-1β） and tumor necrosis factor-α （TNF-α）， as well as elevated ratios of phosphorylated （p）-JAK2/JAK2 and p-STAT3/STAT3 （P<0.01）. Compared with the model group， the PF group and donepezil group exhibited shortened escape latency and increased platform crossings and time spent in the target quadrant （P<0.05， P<0.01）， decreased expression levels of IL-1β and TNF-α， upregulated mRNA levels of interleukin-4 （IL-4） and interleukin-10 （IL-10）， and reduced ratios of p-JAK2/JAK2 and p-STAT3/STAT3 （P<0.05， P<0.01）. ConclusionPaeoniflorin can alleviate cognitive impairment and neuroinflammation in the rat model of AD by inhibiting the JAK2/STAT3 signaling pathway.

ObjectiveTo investigate the intervention effects and mechanisms of the flavonoid hyperoside （Hyp） on lipopolysaccharide （LPS）-induced inflammation in the zebrafish model. MethodsZebrafish larvae were either microinjected with 0.5 g·L^-1 LPS or immersed in 1 g·L^-1 LPS for the modeling of inflammation. The larvae were then treated with Hyp at 25， 50， and 100 mg·L^-1 through immersion for four consecutive days. The inflammatory phenotypes were assessed by analyzing the mortality rate， malformation rate， body length， and yolk sac area ratio. Behavioral tests were conducted to evaluate the inflammatory stress responses， and macrophage migration was observed by fluorescence microscopy. Additionally， the mRNA levels of inflammation-related genes， including interleukin-1β （IL-1β）， interleukin-6 （IL-6）， chemokine C-C motif ligand 2 （CCL2）， chemokine C-X3-C motif receptor 1 （CX3CR1）， chemokine C-C motif receptor 2 （CCR2）， and genes associated with the Toll-like receptor 4 （TLR4）/myeloid differentiation factor 88 （MyD88）/nuclear factor-kappa B （NF-κB） signaling pathway， were measured by Real-time quantitative polymerase chain reaction（Real-time PCR）. ResultsCompared with the pure water injection group， the model group exhibited increased mortality， malformation rates and yolk sac area ratio （P0.01）， reduced body length （P0.01）， increased total swimming distance and high-speed swimming duration （P0.01）， and up-regulated mRNA levels of TLR4， MyD88， NF-κB， IL-1β， IL-6， CCL2， CX3CR1， and CCR2 （P0.01）. Hyp at low， medium and high doses， as well as aspirin， reduced the mortality and malformation rates （P0.05，P0.01）， increased the body length （P0.05，P0.01）， decreased the yolk sac area ratio （P0.01）， reduced the high-speed swimming duration （P0.01）， and down-regulated the mRNA levels of TLR4， MyD88， NF-κB， IL-1β， IL-6， CCL2， CX3CR1， and CCR2 （P0.05，P0.01） compared with the model group. ConclusionHyp may modulate the TLR4/MyD88/NF-κB pathway to ameliorate inflammatory phenotypes and alleviate stress conditions in zebrafish， thereby exerting the anti-inflammatory effect.

Objective To investigate the effects of governor vessel pushing manipulation on behavioral outcomes in valproic acid(VPA)-induced autism spectrum disorder(ASD)rats and explore its underlying mechanisms using prefrontal RNA sequencing(RNA-Seq).Methods Nine Sprague-Dawley pregnant rats at gestational day 12.5 were divided into two groups,six received intraperitoneal VPA injection(600 mg/kg)for modeling,and three received saline.Male offspring at postnatal day 21 were evaluated using the three-chamber social test and open field test to validate the ASD model.VPA-induced male offspring were randomly assigned to the model group(n=5)or tuina group(n=5),while saline offspring formed the blank group(n=5).The blank group and model group received no intervention,while the tuina group underwent governor vessel pushing manipulation stimulation along the governor vessel using a custom device,twice a day for 14 days,totaling 28 times.Post-intervention,behavioral assessments included social index(SI)and social preference index(SPI)in the three-chamber test,total distance traveled and central zone time in the open field test,marble-burying test for stereotyped behaviors,and Nissl staining for prefrontal cortical neuron survival.RNA-Seq identified differentially expressed genes(DEGs)in the prefrontal cortex,followed by Gene Ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)enrichment analyses.Real time fluorogenic quantitative PCR(RT-qPCR)validated DEGs,and Western blotting analyzed proteins in enriched pathways.Results Pre-intervention,both model and tuina groups showed reduced SI,SPI,total distance,and central zone time compared to the blank group(P<0.05),confirming successful modeling.Post-intervention,the model group exhibited lower SI,SPI,total distance,central zone time,increased marble-burying(P<0.05),and fewer Nissl bodies(P<0.01)versus the blank group.Compared to the model group,the tuina group displayed improved SI,SPI,total distance,central zone time(P<0.05),reduced marble-burying(P<0.05),and increased Nissl bodies(P<0.01).RNA-Seq revealed 213 prefrontal DEGs(181 upregulated,32 downregulated)in the tuina group.GO analysis highlighted cellular components,while KEGG identified 181 pathways,with 67 significantly enriched(P<0.05),notably the phosphatidylinositol 3-kinase(PI3K)/protein kinase B(AKT)pathway.RT-qPCR confirmed decreased collagen type Ⅰ alpha 2(Col1α2),transforming growth factor-α(TGF-α),epidermal growth factor receptor 3(ErbB3),and serum/glucocorticoid regulated kinase 2(Sgk2)(P<0.05),and increased hepatic growth factor(Hgf)(P<0.01)in the model group,reversed by governor vessel pushing manipulation.Western blotting showed reduced prefrontal NRG1,ErbB3,nNOS,PI3K,AKT,p-nNOS,p-PI3K,and p-AKT in the model group(P<0.05),which were upregulated by tuina.Conclusion Governor vessel pushing manipulation ameliorates social deficits,anxiety,stereotyped behaviors,and neuronal loss in ASD rats,potentially via activation of the PI3K/AKT signaling pathway.
