Objective: To identify early clinical predictors associated with dysphagia and delayed swallowing recovery in patients with traumatic brain injury (TBI). Methods: In this retrospective study, we enrolled adult TBI patients admitted to the rehabilitation unit of a tertiary medical center between June 2019 and June 2023. Data on baseline characteristics, neurological status, imaging findings, and rehabilitation-related variables were collected. Swallowing function was assessed using two indicators: (1) nasogastric (NG) tube retention and (2) the Functional Oral Intake Scale (FOIS) scores at 1, 4, and 12 weeks post-injury. Regression analyses were conducted to identify predictors associated with dysphagia and swallowing recovery. Results: A total of 160 patients were included. At 1 week post-injury, longer intensive care unit (ICU) stay, poor initial sitting balance and use of sedative medication in ICU were associated with NG tube retention. At 4 weeks, lower initial Rancho Los Amigos Scale (RLAS) scores, immobility-related complications, longer hospitalization, and temporal lobe hematomas were associated with persistent NG tube dependence. By 12 weeks, older age, delayed ability to follow commands, and poor initial sitting balance remained associated with NG tube retention. FOIS outcomes were also associated with older age, delayed time to follow commands, impaired initial sitting balance, prolonged ICU stay, temporal lobe hematomas, lower initial RLAS scores, immobility-related complications, prolonged endotracheal tube placement and extended hospital stays. Conclusion Impaired cognitive status, poor physical function, immobility-related complications, and temporal lobe hematomas were key factors associated with dysphagia and delayed oral intake in individuals with TBI.

Background: and Purpose Vertebrobasilar fusiform aneurysms (VBFAs) carry substantial morbidity and mortality, but optimal management for unruptured VBFAs remains unclear. We compared the safety and efficacy of conservative management (CM), stent-assisted coiling (SAC), and flow diverters (FDs) in patients with unruptured VBFAs, focusing on long-term prognosis. Methods: This study included data from a nationwide Chinese cohort of patients with vertebrobasilar dissecting aneurysms. Inverse probability of treatment weighting (IPTW) balanced confounders across groups. The primary outcome was poor prognosis (modified Rankin Scale score >2). Secondary outcomes included aneurysm rupture, ischemic stroke, compression symptoms, and VBFA-related deaths. Logistic regression estimated odds ratios (ORs) and 95% confidence intervals (CIs). Subgroup and sensitivity analyses were performed. Results: Among 1,115 patients with unruptured VBFAs, 838 (median age, 54 years; 655 men) were included. After IPTW, baseline characteristics were balanced. Median follow-up was 54 months. FD was associated with a lower risk of poor prognosis than CM (OR, 0.48 [95% CI, 0.30 to 0.77]; p=0.002), with no difference between CM and SAC. FD also reduced aneurysm rupture (OR, 0.20 [95% CI, 0.07 to 0.60]; p=0.004) and compression symptoms (OR, 0.30 [95% CI, 0.13 to 0.68]; p=0.004) versus CM. Time-to-event analyses further revealed significant differences in vertebral artery lesions and Type I–II VBFAs, whereas no significant differences were observed in basilar or vertebrobasilar junction lesions or in Type III–IV VBFAs. Conclusions Compared with CM, FD was associated with improved long-term outcomes in unruptured VBFAs, particularly in vertebral artery lesions and Type I–II VBFAs, although residual confounding cannot be excluded.

Background: Patients with coarctation of the aorta (CoA) and an interrupted aortic arch (IAA) may present with small mitral valves (MVs) and a reduced left ventricular (LV) volume. Biventricular repair (BVR) in these patients is dependent on adequate size of the left cardiac structures.Purpose: This study evaluated the impact of the hemodynamic characteristics of atrial septal defects (ASDs) on MV growth following surgical repair. Methods: We retrospectively reviewed the data of patients diagnosed with CoA or IAA between 2007 and 2024. The z score for MV size measured 6 months postoperatively (Z2) was compared with the preoperative MV size (Z1). The factors associated with MV growth were also studied. Results: A total of 161 patients with CoA or IAA were included. Transthoracic echocardiography was used to assess the MV and LV dimensions preoperatively and 6 months postoperatively. Of the cohort, 155 (96.3%) underwent initial BVR and 6 underwent single-ventricle palliation. MV z scores significantly increased following BVR (mean change: +0.45±1.35; P<0.001) but decreased after single-ventricle repair (-0.56±0.49, P=0.04). Multivariate analysis identified the initial MV z score and ASD pressure gradient as independent predictors of MV growth (R2=0.39). Conclusion Annular growth of the MV was not observed in patients who underwent single-ventricle palliation. In contrast, among patients who achieved BVR, those with a small preoperative MV annulus and low ASD pressure gradient demonstrated subsequent catch-up MV growth, suggesting that adequate left-sided preload is essential for MV development.

AIM:To evaluate the efficacy of inflix-imab in the maintenance of Perianal fstulizing Crohn's disease.METHODS:The clinical data of 24 patients with perianal fistula Crohn's disease(PFCD)treated with infliximab(IFX)in the Depart-ment of Anorectal Surgery of our hospital from No-vember 2020 to October 2023 were retrospectively collected.The clinical efficacy and safety were eval-uated by observing the clinical characteristics for 54 weeks.The fistula remission rate,clinical remis-sion rate,and endoscopic remission rate of pa-tients were calculated.The changes of laboratory indexes before and after treatment were recorded.Logistic regression was used to analyze the related factors of fistula remission.All adverse reactions oc-curred during IFX treatment were recorded.RE-SULTS:After 54 weeks of IFX treatment,the fistula remission rate,clinical remission rate,and endo-scopic remission rate were 37.5％,45.83％,and 33.33％,respectively.Fistula response at 14 weeks of treatment(OR=19.419,95％CI:1.267-297.559,P=0.033)was predictive factors for fistula remission at 54 weeks of treatment.The inflammatory index-es and nutritional indexes were significantly im-proved compared with those before treatment(P＜0.01).The scores of PDAI,CDAI and SES-CD were significantly different from those before treatment(P＜0.01).Five patients(20.83％)had adverse reac-tions,and the symptoms disappeared or improved after symptomatic treatment,and no patient had serious adverse reactions.CONCLUSION:IFX can ef-fectively promote the closure of PFCD fistula,im-prove the chronic inflammatory reaction of intesti-nal mucosa,alleviate clinical symptoms,and im-prove the quality of life of patients.IFX is effective and safe for PFCD maintenance treatment.

Aim To explore the effects of nuciferine on cognitive behavior and the underlying mechanisms,white matter injury(WMI),neuroinflammation,and ferroptosis in mice with chronic ischemic WMI.Meth-ods Sixty C57BL/6 mice were divided into a control group,a bilateral common carotid artery stenosis(BCAS)model group,and low/high-dose nuciferine groups(20/40 mg·kg-1).A chronic ischemic WMI model was established using BCAS surgery.Following eight weeks of treatment,cognitive behavior(Y-maze,novel object recognition,Morris water maze),white matter integrity(LFB/MBP staining),microglial acti-vation(Iba-1 immunofluorescence),inflammatory cy-tokines(ELISA for TNF-α,IL-1β,IL-6),ferroptosis markers(Fe2+,ROS,MDA,GSH),mitochondrial ultrastructure(electron microscopy),and protein ex-pression of the PI3K/Akt and NRF2/xCT/GPX4 signa-ling pathways(Western blot)were evaluated.Results Compared with the control group,the BCAS group showed significant cognitive decline(P＜0.05),re-duced myelin density,elevated inflammatory cytokines and ferroptosis markers(Fe2+,ROS,MDA),shrunk-en mitochondria,and downregulated PI3K/Akt and NRF2/xCT/GPX4 pathway proteins(P＜0.05).Nu-ciferine intervention significantly ameliorated these in-juries in BCAS mice,with the high-dose group exhibi-ting superior effects(P＜0.05).Conclusions Nu-ciferine exerts protective effects against chronic ische-mic WMI and cognitive impairment by activating the PI3K/Akt and NRF2/xCT/GPX4 signaling pathways,thereby suppressing neuroinflammation and ferroptosis.

Aim To examine the pathogenesis of disul-fide death gene in vascular dementia(VD)by bioin-formatics analysis of disulfide death differentially ex-pressed genes(DEGs)combined with experimental verification.Methods The death DEGs of disulfide were screened and their correlation was analyzed.The VD patients data in the data set were analyzed by clus-tering and typing and gene set variation.The clustering risk of DEGs was tested with a nomogram model,and the optimal learning model was predicted.After the es-tablishment of VD rat model,water maze test,HE stai-ning and RT-qPCR detection were performed to verify the results of health information.Results Four DEGs including SLC7A11 were obtained,which had antago-nistic or synergistic interaction with each other.The genetic data could be divided into two subtypes with significant differences.After typing,VD disulfide DEGs were mainly concentrated in GnRH signaling pathways.The accuracy of the nomogram prediction model was high.Generalized linear was the best ma-chine learning model.Compared with the sham opera-tion group,the escape latency of rats in the model group was prolonged,the number of crossing platforms decreased,the relative mRNA expression levels of Slc3a2 and Slc7a11 decreased,and LRPPRC in-creased.Conclusions SLC7A11 and other disulfide death DEGs and its related GnRH signaling pathway may be an important part of the pathogenesis of VD di-sulfide death.SLC3A2,LRPPRC and SLC7A11 can be used as characteristic genes in the regulation of VD by disulfide death,which may affect VD progression through the regulation of disulfide death.

This study aims to determine the therapeutic effect and then elucidate the molecular mechanism of Dietary Yangrong Decoction(DYRT)on blood deficiency syndrome based on net-work pharmacology and study its active compounds.The molecular mechanism of DYRT in the treatment of blood deficiency syndrome was predicted by network pharmacology.The blood defi-ciency of rats was established using cyclophosphamide and acetophenohydrazine jointly,which was divided into a blank control group,a model group,a Men's Yangrong Decoction group(MYRT)(positive control group),a medicinal group and food-based Yangrong Decoction group.The active components were analyzed by liquid chromatography-mass spectrometry(HPLC-MS),the periph-eral hemogram was detected by an automatic biochemical analyzer,the levels of hematopoietic regulatory factors in serum were determined by ELISA,and the relative expression of EPO in kid-ney and PI3K,AKT,GM-CSF in bone marrow were measured by RT-PCR.The results showed that DYRT had 57 active ingredients and 128 potential targets for the treatment of spleen deficien-cy syndrome.1 835 items were obtained by GO enrichment analysis,and 20 pathways were ob-tained by KEGG enrichment analysis;DYRT and MYRT were identified by HPLC-MS to contain 12 same blood active compounds.Animal experiments showed that,compared with the model group,the number of red blood cells,the number of platelets and the content of hemoglobin in the DYRT group were significantly increased,and the number of white blood cells was significantly decreased(P＜0.05).The contents of EPO,IL-3,IL-6 and GM-CSF in serum were significantly in-creased,and the content of TNF-α was significantly decreased(P＜0.05).The relative expression levels of EPO in kidney and PI3K,AKT and GM-CSF mRNA in bone marrow were significantly increased(P＜0.05).Compared with the MYRT group,the number of white blood cells in the DYRT group was significantly reduced,the content of GM-CSF in serum was significantly in-creased,and the content of EPO and GM-CSF mRNA was significantly increased(P＜0.05).In conclusion,DYRT contains the same active compounds as MYRT,which can regulate hematopoi-etic factors,thereby activating the PI3K/AKT pathway to restore hematopoietic function and im-prove the blood deficiency state of the body.

Objective:To explored the application value of dynamic susceptibility contrast-perfusion weighted imaging(DSC-PWI)combined with amide proton transfer(APT)imaging in brian glioma grading.Methods:Retrospective analysis of clinical data of 100 patients with brian glioma admitted to The Second Affiliated Hospital of Xinjiang Medical University from January 2022 to September 2024.They were divided into a low-grade group(WHO grades Ⅰ-Ⅱ,n=62)and high-grade group(WHO grades Ⅲ-Ⅳ,n=38)according to the World Health Organization(WHO)grading system for tumors.All patients underwent DSC-PWI and APT imaging preoperative examinations.Apparent diffusion coefficien(ADC),cerebral blood volume(CBV),cerebral blood flow(CBF),mean transit time(MTT),time to peak(TTP),maximum APT value(APTmax),minimum APT value(APTmin),the average APT value of the whole lesion(APTwhole)were recorded.The general datas and ADC,CBV,CBF,MTT,TTP,APTmax,APTmin,APTwhole of two group were compared.The influencing factors of high-grade brian glioma were analysed by Multivariate logistic regression.The diagnostic value of high-grade brian glioma was analysed of DSC-PWI combined with APT imaging by receiver operating characteristic(ROC)curve.Results:There was no statistically significant difference in age,gender,lesion location,basilar artery occlusion,necrosis and growth pattern between the two groups(P＞0.05),there was a statistically significant difference in the maximum diameter of lesions ≥2 cm and cystic lesions(P＜0.05).The ADC of the high-gradel group was lower than that of the low-grade group,while APTmax,APTmin,APTwhole,CBF,CBV,MTT and TTP were all higher than those of the low-grade group(P＜0.05).Elevated APTmax,APTmin,CBV,MTT,and TTP were risk factors for high-grade brian glioma(P＜0.05),while elevated ADC was a protective factor(P＜0.05).The results of ROC analysis showed that,the area under the curve(AUC)values of APTmax,APTmin,ADC,CBV,MTT,and TTP for diagnostic high-grade brian glioma were 0.830,0.868,0.852,0.843,0.803 and 0.827(all P＜0.05).The results of ROC analysis showed that,the AUC values of the logistic model for diagnostic high-grade brian glioma was 0.993.Conclusion:Single detection of DSC-PWI and APT imaging parameters has high diagnostic value in brian glioma grading,and combined detection of APTmax,APTmin,ADC,CBV,MTT and TTP imaging parameters can further improve diagnostic accuracy.
