This study aims to explore protective effects of Lycium barbarum polysaccharides(LBP)on intestinal damage caused by lipopolysaccharide(LPS)-induced inflammatory bowel disease(IBD)in chicks.Network pharmacology was initially employed to determine the target proteins of wolfberry in the prevention and treatment of IBD.Following this,protein-protein interaction analy-sis,GO and KEGG pathway enrichment analysis,and molecular docking studies were conducted.Subsequently,an animal study was conducted:a total of 100 one-day-old male Hy-line brown lay-ing hens were randomly divided into five groups:a blank control group(CON),an LPS treatment group(LPS),a low-dose LBP group(LPS+LBP 0.25 g/L,L-LBP),a medium-dose LBP group(LPS+LBP 0.5 g/L,M-LBP),and a high-dose LBP group(LPS+LBP 1 g/L,H-LBP).Upon reac-hing 21 days old,duodenal,jejunal,ileal,and cecal tissues were collected to determine SOD and GSH-Px levels.Furthermore,the mRNA expression levels of TNF-α,AKT1,IL-6,IL-1β and TP53 in the intestinal tissues were measured using quantitative real-time PCR.The results demonstrated that network pharmacology identified 45 active ingredients in wolfberry that target 116 key protein sites,including TNF,AKT1 and IL6.The primary objectives focus on signaling pathways including AGE-RAGE,IL-17,TNF,HIF-1,and NF-κB.Molecular docking showed excellent ligand-receptor docking scores,with stable binding facilitated by hydrogen bonds and hydrophobic interactions.Compared to the LPS group,the 0.5 g/L LBP exhibited notably higher levels of SOD and T-AOC.In comparison with the LPS group,the medium and high-dose LBP experimental groups showed notably decreased the mRNA expressions of TNF-α,AKT1,IL-6,and IL-1β,while TP53 mRNA expression was significantly upregulated(P＜0.01).In summary,wolfberry exerts preventive and therapeutic effects on IBD through a multi-component,multi-target,and multi-pathway mecha-nism.

Objective:To analyze the factors influencing the prognoses of stroke survivors with pseudobulbar palsy (PBP) dysphagia and construct a prediction model.Methods:Data on two hundred and fifty-one stroke survivors with PBP dysphagia were collected and analyzed retrospectively. The subjects were divided into a good prognosis group ( n=164) and a poor prognosis group ( n=87) according to the results of Kubota water swallowing tests administered at discharge. Their clinical data were analyzed using univariate correlation analysis, and the statistically significant independent variables found were further analyzed using multivariate logistic regression to obtain the important predictors of prognosis. R software was then used to assemble the useful factors into a nomogram prediction model. The area under the receiver operating characteristics (ROC) curve was employed to verify the model′s predictive power. Results:According to the univariate correlation analysis, significant differences were found between the two groups′ average National Institutes of Health Stroke Scale (NIHSS) scores, mouth opening grades and ages. The multivariate logistic regression analysis showed that NIHSS score, mouth opening grade and age could be useful and independent predictors of poor prognosis. The ROC curve analysis showed that the area under the curve for the nomogram model was 0.727, with a sensitivity of 59.8% and a specificity of 81.6%, suggesting that the model had good predictive power and was properly calibrated.Conclusions:NIHSS score, mouth opening grade and age are independent predictors of prognosis for stroke patients with PBP dysphagia. The nomogram model constructed in this study is of great value in developing a prognosis for such patients, which is helpful in the prevention and treatment of post-stroke dysphagia.

Objective:To investigate the effects of annulus fibrosus(AF)suture or not on the lumbar biome-chanics following microendoscopic discectomy(MED)through establishing finite element models(FEMs)of unsu-tured AF incision and sutured AF incision.Methods:A 27-year-old healthy young adult male volunteer was recruited and underwent lumbar CT to exclude spinal deformities,tumors,and other osseous pathologies.CT images of the L4/L5 segment were imported into the software Mimics for three-dimensional reconstruction and contour extraction.The resulting model was further processed using Geomagic,SolidWorks,and Workbench for solid modeling.An intact L4/5 segment model,an L4/5 model with an unsutured AF incision following MED(unsutured AF model),and an L4/5 model with a sutured AF incision following MED(sutured AF model)were established.Intervertebral range of motion(ROM),Von-Mises stress on the facet joints,and Von-Mises stress on the AF of the models were measured,and model validity was verified by comparison with previously pub-lished studies.After validation,the inferior end of the L5 vertebral body in all the three models was fixed.An axial load of 500N was applied to the superior end of the L4 vertebral body,and a bending moment of 7.5N·m was separately applied under six physiological loading conditions(flexion,extension,left/right lateral bending,and left/right axial rotation).The biomechanical properties of the three models at the L4/5 level,in-cluding intervertebral ROM and Von-Mises stress in facet joints,and Von-Mises stress on the AF were com-pared under different loading conditions.Results:No significant discrepancies were noted when data obtained under these six motion conditions were compared with the findings from prior literature,thus validating the models.Stress nephogram results revealed that under each motion condition,high-stress areas were located at the unsutured defect of the intervertebral disc AF and the surrounding facet joint processes.Compared with the intact model,the intervertebral ROM of the sutured AF model was 8.6802°,8.596°,4.8514°,5.0249°,2.2474°,and 1.9092°,respectively,under the six motions,while that of the unsutured AF model was 8.7475°,8.9453°,5.6441°,5.2546°,2.5886°,and 1.9487°,respectively.The ROM of the sutured AF model was 9％,19％,44％,38％,50％,and 40％higher than that of the intact model;Compared with the unsutured AF mod-el,it was reduced by 1％,4％,14％,4％,13％,and 2％respectively.For Von Mises stress on the AF under the six motion conditions,the stress of the sutured AF model was 2％,65％,21％,32％,51％,and 38％higher than that of the intact model,but 8％,48％,52％,10％,37％,and 48％lower than that of the unsu-tured AF model respectively.For Von-Mises stress in facet joints,the stress values of the sutured AF model were 12.109MPa,8.3601MPa,13.998MPa,12.969MPa,10.219MPa,and 10.074MPa respectively,while those of the unsutured AF model were 13.399MPa,9.6094MPa,18.175MPa,17.967MPa,12.409MPa,and 11.6384MPa respectively.The stress values of Von-Mises stress in facet joints of the sutured AF model was 5％,10％,32％,17％,31％,and 34％higher than that of the intact model;Compared with the unsutured AF model,it was decreased by 9％,13％,22％,27％,17％,and 13％respectively.Conclusions:Among the three con-structed L4/5 FEMs,the sutured AF model exhibits more favorable intervertebral ROM,and Von-Mises stress of facet joints and AF compared with the unsutured AF model.This indicates that AF suture contributes to enhancing intervertebral stability.
