Background:
and Purpose Therapeutic target selection in noninvasive brain stimulation for poststroke motor recovery typically relies on the interhemispheric inhibition model, which is effective for mildly affected patients but offers limited benefits for severely affected individuals. The mechanisms governing recovery from moderate-to-severe stroke remain poorly understood, which hinders the development of targeted interventions.
Methods:
We analyzed resting-state functional magnetic resonance imaging data from patients with unilateral subcortical stroke and moderate-to-severe upper limb deficits, both pre- and postintervention, along with data from healthy controls. We developed a novel dynamic lag analysis method for identifying recovery-related homotopic sensorimotor regions with altered interhemispheric interactions. To further uncover the global reorganization pathway, we developed dynamic lateralization approaches to detect large-scale functional connectivity (FC) alterations associated with the identified regions in transient lateralization states.
Results:
Dynamic time-lag analysis revealed significantly reduced synchronized states in the homotopic dorsal premotor cortex (PMd) post-intervention compared with pre-intervention, which correlated with motor recovery. Further dynamic lateralization analysis revealed a prolonged segregation state in patients, characterized by weakened interhemispheric and strengthened intrahemispheric interactions. In this state, patients showed decreased FC in the ipsilesional PMd and increased FC in the contralesional PMd with bilateral subcortical networks. These recoveryrelated alterations were absent in the traditional static analysis.
Conclusions
Dynamic analyses targeting interhemispheric interactions are valuable for understanding neural reorganization after stroke. The diminished interactions between the homotopic PMd indicate a compensatory mechanism. Importantly, a state-dependent compensatory pathway was identified, wherein the contralesional PMd assumes the functions of the ipsilesional PMd through enhanced interactions with subcortical structures, potentially guiding more effective interventions.

Objective To investigate the effects of emergency endovascular treatment on the short-term and long-term prognosis of patients with minor stroke(National Institutes of Health stroke scale[NIHSS]score≤5)caused by posterior circulation large vessel occlusion(LVO).Methods A retrospective analysis was performed on consecutive patients with minor stroke caused by posterior circulation LVO admitted to the Department of Neurology,the First Affiliated Hospital of Xi'an Jiaotong University from July 2019 to March 2024.The patients were divided into the emergency endovascular treatment group and the standard medical treatment group according to the treatment method.Baseline and clinical data were collected from all patients enrolled,including age,sex,smoking history,history of alcohol consumption,medical history(hypertension,diabetes,hyperlipidemia,atrial fibrillation,transient ischemic attack[TIA],blood pressure on admission,stroke history,coronary heart disease),intravenous thrombolysis,tandem lesions,posterior circulation Alberta stroke program early CT score(pc-ASPECTS)on admission,NIHSS score on admission and discharge,time from onset to admission,responsible occluded vessel(basilar artery,left vertebral artery,right vertebral artery),vertebral artery development(left vertebral artery dominant,right vertebral artery dominant,bilateral vertebral artery dominant),non-lesion side vertebral artery development(poor,good,not applicable),basilar artery on CT angiography(BATMAN)score,leptomeningeal branch compensation(open,not open),surgery-related indicators(number of thrombectomy passes[≤2 times,>2 times],rescue interventions[stent placement,balloon dilation,arterial thrombolysis,intra-arterial tirofiban infusion],immediate postoperative modified thrombolysis in cerebral infarction[mTICI]grade≥2b[successful recanalization],anesthesia method[general,local],endotracheal intubation status[yes,no],duration of mechanical ventilation[not using a ventilator or successfully intubation for≤24 hours and>24 hours]),in-hospital systematic complications(deep-vein thrombosis,urinary tract infection,lung infection).The primary outcome for short-term prognosis was an excellent outcome(modified Rankin scale[mRS]score of 0-1)within 90 days after onset.Secondary outcomes included a good outcome(mRS score of 0-2)within 90days after onset,recurrent ischemic stroke within 90 days after onset,all-cause mortality within 90 days after onset.Safety outcomes were symptomatic intracerebral hemorrhage(sICH)within 24 hours of treatment(NIHSS score increased by≥4 points or increased level of consciousness score by≥1 point compared with admission,with visible hemorrhagic lesions on follow-up CT scan)and early neurological deterioration(END,NIHSS score increased by≥2 points or motor score increased by≥1 point compared with admission,within 24 hours after treatment).Long-term outcome was defined as recurrent ischemic stroke within 1 year after onset.Short-term and safety outcomes were compared between the emergency endovascular treatment group and the standard medical treatment group.Kaplan-Meier survival curves was used to evaluate the effect of emergency endovascular treatment on the long-term prognosis.Based on the mRS score at 90 days from onset,all patients were divided into an excellent outcome(mRS score 0-1)group and a non-excellent outcome(mRS score 2-6)group.Baseline and clinical data were compared across the two groups.Variables with statistically significant differences were included in the multivariate Logistic regression analysis to investigate the influencing factor of 90-day excellent outcomes in patients with minor stroke caused by posterior circulation LVO.Results A total of 56 patients with minor stroke caused by posterior circulation LVO were enrolled,including 18 patients in the emergency endovascular treatment group and 38 patients in the standard medical treatment group.45 patients achieved excellent outcomes and 11 patients achieved non-excellent outcomes.(1)The emergency endovascular treatment group had lower pc-ASPECTS on admission(8.0[7.0,9.0]points vs.9.0[8.0,10.0]points,P=0.043)and There were no statistically significant differences in the excellent outcome rate,good outcome rate,and ischemic stroke recurrence rate within 90 days after onset between the two groups(all P>0.05).No all-cause mortality occurred within 90 days after onset in either group.In the emergency endovascular treatment group,one patient developed sICH and one developed END within 24 hours after treatment.(3)No recurrent ischemic stroke in the emergency endovascular treatment group within 1 year after onset,while 3cases(7.89%)of recurrence were observed within 1year after onset in the standard medical treatment group.The Kaplan-Meier survival curve analysis showed that there was no statistically significant difference in the incidence of ischemic stroke within one year after onset between the two groups(P=0.341).(4)There were statistically significant differences between patients with excellent outcome and patients with non excellent outcome in drinking history,diabetes history,NIHSS score after discharge,distribution of responsible occlusive vessels,and distribution of vertebral artery development(all P<0.05).The results of multivariate Logistic regression analysis showed that the NIHSS score at discharge was an independent influencing factor for excellent outcome at 90 days after onset in patients with minor stroke caused by posterior circulation LVO(OR,0.448,95%CI 0.275-0.728,P=0.001).Conclusions This study shows potential safety and effectiveness of emergency endovascular treatment on patients with minor stroke caused by posterior circulation LVO,but it is not superior to standard medical treatment in terms of short-term and long-term outcomes.Further large-sample randomized controlled trials are warranted to validate the findings of this study.

Objective This study aimed to investigate the correlation of cerebral perfusion and cognitive function status in patients with minor stroke(MS)or transient ischemic attack(TIA)complicated by severe intracranial arterial stenosis or occlusion(hereafter referred to as ICAS-MSTIA).Methods Retrospectively enrol consecutive ICAS-MSTIA patients admitted to the Department of Neurology,the First Affiliated Hospital of Xi'an Jiaotong University,from June 2023 to May 2024.In the meantime,healthy controls were openly recruited.The ICAS-MSTIA patients were divided into two groups based on the side of intracranial large artery stenosis or occlusion:the left intracranial large artery involvement group and the right intracranial large artery involvement group.All patients with intracranial large artery stenosis or occlusion underwent MR scanning within 2 weeks after the first episode of TIA or MS,while there was no specific time requirement for MR examination in the healthy control group.On the day of MR scanning,the Montreal cognitive assessment(MoCA)scale was used to evaluate the participants'global cognitive function and performance in various cognitive domains,including visuospatial/executive function,naming,attention,language,abstraction,delayed recall,and orientation.General information of all participants was collected,including age,sex,educational level,body mass index,and history of smoking and alcohol consumption.Clinical data were collected from both left and right intracranial large artery involvement groups,including cerebrovascular risk factors(such as,diabetes mellitus,hypertension,and hyperlipidemia),National Institutes of Health stroke scale(NIHSS)score at admission,responsible stenotic or occluded arteries(internal carotid artery,middle cerebral artery),degree of stenosis in the responsible vessel(severe stenosis[stenosis rate 70%-99%],occlusion[stenosis rate100%])and non-responsible vessel(no stenosis[0],mild stenosis[stenosis rate>0-49%]),collateral circulation compensation(American Society of Interventional and Therapeutic Neuroradiology/Society of Interventional Radiology[ASTIN/SIR]collateral circulation classification),and responsible events(TIA,MS).General data and MoCA scale scores were compared across the three groups,while clinical data were compared between the left and right intracranial large artery involvement groups.Statistical parametric mapping 12(SPM 12)was used to perform voxel-wise independent samples t-tests on cerebral blood flow(CBF)differences among the left ICAS-MSTIA group,right ICAS-MSTIA group,and healthy control group,with cluster-level family-wise error(FWE)correction applied for adjustment.Multiple linear regression analysis was conducted to evaluate the relationship between global CBF values and total MoCA scores in ICAS-MSTIA patients with left or right intracranial large artery involvement.Results A total of 33 ICAS-MSTIA patients and 33 healthy controls were enrolled in the study.Among the ICAS-MSTIA patients,21 had left intracranial large artery involvement and 12 had right involvement.(1)Among the three groups,statistically significant differences were observed in the proportions of individuals with reported smoking history(P=0.024)and alcohol consumption history(P=0.011).The left intracranial large artery involvement group had a higher NIHSS score(0[0,2]vs.0[0,0],P=0.044)and a higher proportion of patients with internal carotid artery involvement(13/21 cases vs.2/12 cases,P=0.027)compared with the right side group.No statistically significant differences were observed in other general or clinical data across the three groups or between the two non-control groups(all P>0.05).(2)Statistically significant differences were found across the three groups in the MoCA scale total score and scores of visuospatial/executive function,attention,language,abstraction,delayed recall,and orientation cognitive domains(all P<0.05),while no significant difference was noted in the naming score(P=0.063).The left intracranial large artery involvement group had lower total MoCA score and lower scores in visuospatial/executive function,attention,language,abstraction,delayed recall,and orientation in comparison to the healthy control group(all P<0.016 7).The right intracranial large artery involvement group had significantly lower scores in language,abstraction,and orientation domains than the healthy control group(all P<0.016 7).Additionally,the left side group had a lower attention domain score than the right side group(P<0.016 7).No other statistically significant differences were found in pairwise comparisons(all P>0.016 7).(3)Patients in both the left and right intracranial large artery involvement groups exhibited a significant decrease in CBF in extensive regions on the affected side,including the temporal lobe,dorsolateral prefrontal cortex,and occipital lobe.Furthermore,after correction,in the left involvement group CBF was higher in the contralateral lingual gyrus,cuneus,and calcarine sulcus compared with the healthy control group(P<0.05).While in the right involvement group,no regions had increased CBF compared to the healthy control group.(4)Multiple linear regression showed positive correlation between CBF in ipsilateral precentral gyrus and superior temporal gyrus,and the total MoCA score in patients with left intracranial large artery involvement(FWE-corrected,P<0.05).In contrast,there was no correlation between CBF and total MoCA score in patients with right intracranial large artery involvement.Conclusions ICAS-MSTIA patients exhibited various degrees of impairment in cerebral perfusion and cognitive function.A significant positive correlation is observed between these two impairments in patients with left intracranial large artery involvement.

Allergic rhinitis(AR)affects 10%-40%of the population in the world.Because CLOCK genes regulate the circadian rhythms of AR,the symptoms in parts of the patients are aggravated in the morning and evening and relieved at moon.Although lots of studies showed that traditional Chinese medicine is effective for AR,further explores are still needed to analyze the circadian rhythm of AR based on Chinese Chronological Medicine for controlling the circadian outbreak point of symptoms of AR in daily cycle.We supposed that Weiyang might play an important role for controlling the circadian rhythm of AR with closed similarities with the tidal variation of the expressions of CLOCK genes.Thus based on Weiyang theory,we tried to clarify the mechanism of circadian rhythm of AR and explore the relationship between Weiyang and the CLOCK genes so as to further expand the treatment methods of adjusting the circadian cycle of AR with TCM and improve the corresponding therapeutic efficacy.

Objective:To investigate the impact of delayed ileostomy closure (>6 months) on postoperative complications in patients with ulcerative colitis (UC) undergoing ileal pouch-anal anastomosis (IPAA) .Methods:Using propensity score matching. Clinical data of UC patients who underwent IPAA and subsequent ileostomy closure at Jinling Hospital from January 2014 to December 2021 were retrospectively analyzed. Patients were categorized into a routine group (2 to ≤6 months) and a delayed group (>6 months) based on the timing of ileostomy closure. A 1∶1 propensity score matching analysis was performed to compare early (≤30 days) and late (>30 days) postoperative complications between the two groups.Results:A total of 225 UC patients who underwent IPAA and ileostomy closure were included, comprising 129 males (57.3%) and 96 females (42.7%). After propensity score matching, 88 patients were included in the analysis, with 44 patients in each group. There was no significant difference in the overall incidence of early postoperative complications (11.4% vs. 15.9%, P = 0.534) or late postoperative complications (43.2% vs. 43.2%, P = 1.000) between the delayed and routine groups. Additionally, no significant differences were observed in other postoperative complications (all P > 0.05) . Conclusion:Delayed ileostomy closure following IPAA does not significantly increase the risk of postoperative complications in UC patients.

Objective To evaluate the efficacy of cefoperazone-sulbactam(CS)combined with ulinastatin in the treatment for stroke-associated pneumonia(SAP)after endovascular treatment of acute large vessel occlusive stroke(AIS-LVO).Methods This study retrospectively included patients who developed SAP after endovascular treatment of AIS-LVO admitted to the intensive care unit of the Department of Neurology at the First Affiliated Hospital of Xi'an Jiaotong University from March 2022 to December 2023.Patients were randomly divided into the ulinastatin group(combined application of ulinastatin and CS)and the control group(sole application of CS)using a random number table.Baseline and clinical data,including sex,age,infarct laterality,culprit vessel,trial of Org 10172 in acute stroke treatment(TOAST)classification,baseline National Institutes of Health stroke scale(NIHSS)score,baseline Glasgow coma scale(GCS)score,medical history(hypertension,diabetes,coronary heart disease,atrial fibrillation,past history of stroke),history of smoking and alcohol consumption,admission baseline blood pressure,laboratory test results at admission(including red blood cell count,white blood cell count,neutrophil count,platelet count,random blood glucose levels,albumin,creatinine,low-density lipoprotein cholesterol,uric acid,and D-dimer),and endovascular therapies(including mechanical retrieval of thrombus,stenting,balloon dilatation,arterial thrombolysis and combination therapy)were collected from both groups.After the diagnosis of SAP,patients in both groups underwent conventional treatment such as sputum expectoration and clearance,antipyretic and antitussive treatment,oxygen therapy,respiratory support,fluid and nutrition support,along with CS anti-infective therapy.In contrast to the control group,the ulinastatin group additionally received continuous ulinastatin treatment for at least 7 days.The adverse reactions of the two groups after initiating SAP treatment including allergic reactions(such as sudden dyspnea,skin redness,and shock),decrease in peripheral white blood cell count(below 4.0 × 109/L),nausea and vomiting,diarrhea,rash and/or itching,and liver enzymes(aspartate aminotransferase or alanine aminotransferase)elevation(more than twice the upper limit of normal)were compared between the two groups.The efficacy indicators encompassing arterial blood gas analysis(oxygenation index)and inflammatory factor indicators(interleukin-6[IL-6],procalcitonin)after 7 days of SAP treatment,pneumonia-related symptoms and signs before and after SAP treatment(including body temperature,heart rate,respiratory rate,sputum volume and characteristics,changes in lung rales,etc.),imaging examinations(such as head CT and chest CT).The evaluation of therapeutic efficacy is classified as(1)markedly effective:following treatment,significant relief was observed on pneumonia-related symptoms and signs,with body temperature returned to normal,and arterial blood gas analysis and inflammatory factor indicators returned to normal levels;post-treatment imaging studies reveal that over 2/3 of lung inflammation has been absorbed;(2)effective:after treatment,some improvement was observed in pneumonia-related symptoms and signs,with mild improvement in arterial blood gas analysis and inflammatory factor indicators;post-treatment imaging studies reveal some absorption of lung inflammation;(3)ineffective:no improvement or further deterioration of pneumonia-related symptoms,arterial blood gas analysis,and inflammatory factor indicators after treatment.The arterial blood gas analysis,inflammatory factor indicators and efficacy indicators were evaluated and compared between the control and the ulinastatin group.Compare the prognosis(improvement of the lesion in the chest CT after 7 days of treatment,length of stay in the intensive care unit,total length of hospital stay,and modified Rankin scale[mRS]score assessed via telephone follow-up or outpatient revisit 90 days after endovascular treatment[with an mRS score ≤2 indicating a good prognosis],as well as mortality).Results A total of 99 patients with AIS-LVO who developed SAP after endovascular treatment were included in this study,with 69 males(69.7%)and 30 females(30.3%),and an average age of(68±10)years.Among them,there were 46 cases in the ulinastatin group and 53 cases in the control group.(1)No statistically significant differences were observed in baseline or clinical characteristics between the two groups(all P>0.05).(2)The overall effective(markedly effective and effective)rate of SAP treatment was greater in the ulinastatin group than that in the control group(89.1%[41/46]vs.69.8%[37/53],P=0.019).(3)No statistically significant differences were observed in serum IL-6 levels,procalcitonin levels,or arterial oxygenation index between the ulinastatin group and the control group before treatment(all P>0.05).seven days after treatment,the levels of serum IL-6([21.13±14.86]ng/L vs.[64.39±52.95]ng/L)and procalcitonin([0.12±0.11]μg/L vs.[0.31±0.20]μg/L)in the ulinastatin group were significantly lower compared to those before treatment(all P<0.01),and the arterial oxygenation index was significantly higher than that before treatment([359.35±92.56]mmHg vs.[273.34±95.65]mmHg,P<0.01).Seven days after treatment,the levels of serum IL-6([21.13±14.86]ng/L vs.[31.90±21.95]ng/L)and procalcitonin([0.12±0.11]μg/L vs.[0.26±0.24]μg/L)in the ulinastatin group were significantly lower than those in the control group(all P<0.01),and the arterial oxygenation index was significantly higher than that of the control group([359.35±92.56]mmHg vs.[314.81±81.97]mmHg,P=0.020).(4)In the ulinastatin group,there was 1 case of nausea and vomiting,1 case of itching and/or rash,and 1 case of elevated liver enzymes,resulting in an adverse reaction rate of 6.5%(3/46).In the control group,there were 2 cases of nausea and vomiting,1 case of itching and/or rash,and 1 case of elevated liver enzymes,resulting in an adverse reaction rate of 7.5%(4/53).No statistically significant differences were observed in the adverse reaction rate between the two groups(P>0.05).(5)After 7 days of treatment,the ulinastatin group exhibited a greater improvement rate in chest CT lesions compared to the control group(93.5%[43/46]vs.77.4%[41/53],P=0.026).No statistically significant differences were observed between the two groups in terms of the length of stay in the intensive care unit or the total length of hospital stay(both P>0.05).Additionally,the 90-day mortality rate after intravascular treatment was lower in the ulinastatin group compared to the control group(6.5%[3/46]vs.20.8%[11/53],P=0.040).No statistically significant differences were observed in the good prognosis rate between the two groups(P=0.119).Conclusions Combined treatment with CS and ulinastatin can improve the clinical symptoms,inhibit inflammatory factors and reduce mortality rate in SAP patients after receiving endovascular treatment for AIS-LVO.The results of this study still need to be further confirmed by large-scale prospective studies.

To satisfy the growing healthcare demands of the public, it is essential to develop a public service platform for vaccination. This initiative aligns with national policies, optimizes resource allocation, innovates service models, enhances service efficiency, and reduces service costs. Drawing on relevant national policies and regulatory requirements, as well as the notable achievements and practical experiences gained through the exploration and innovation of vaccination service models across various regions, this paper proposes expert recommendations. It defines the essential components and functional specifications for public service platforms, focusing on public needs such as electronic vaccination record management, appointment management, the promotion of electronic vaccination certificates, vaccination certificate verification for school enrollment, vaccination site navigation, and science communication and public engagement. The recommendations aim to serve as a reference for the development of vaccination public service platforms nationwide.

Objective To investigate the neurovascular coupling(NVC)status in the acute phase of patients with minor ischemic stroke(MIS)or transient ischemic attack(TIA)due to intracranial large artery moderate-to-severe stenosis or occlusion using multimodal MRI techniques and to explore its correlation with quality of life(QoL).Methods This prospective,consecutive study enrolled patients with MIS or TIA due to intracranial large artery moderate-to-severe stenosis or occlusion form the Department of Neurology,the First Affiliated Hospital of Xi'an Jiaotong University,between June 2022 and October 2023.Recruit healthy subjects with matched age,sex,and handedness form the community during the same period.Patients were divided into left-sided involvement and right-sided involvement groups based on the affected side of the responsible vessel,while the healthy subjects were set as the healthy control group.Post-hoc power analysis was performed using G*Power 3.1 software.General characteristics(age,gender,body mass index,education level)were collected and compared across all three groups.Clinical data and QoL assessment were collected and compared between the two patient groups.Collected clinical data including type of cerebrovascular events(TIA,MIS),the National Institutes of Health stroke scale(NIHSS)score at admission,the responsible vessel(internal carotid artery,middle cerebral artery)and its side location,the degree of responsibility artery stenosis(moderate-severe stenosis[50%-99%stenosis rate],occlusion[100%stenosis rate]),the intracranial collateral circulation status(American Society of Interventional and Therapeutic Neuroradiology/Society of Interventional Radiology[ASITN/SIR]collateral circulation grading),cerebrovascular risk factors(hypertension,diabetes,hyperlipidemia,smoking history),and the laboratory test indicators at admission(glycated hemoglobin,triglycerides,total cholesterol,high-density lipoprotein cholesterol,low-density lipoprotein cholesterol,blood uric acid,blood homocysteine).QoL was assessed using the stroke impact scale(SIS),covering eight functional domains and a patient-reported overall recovery item.Multimodal MR data were acquired for all subjects.Whole-brain cerebral blood flow(CBF)images were generated using statistics parameter mapping 12(SPM 12)software,while regional homogeneity(ReHo)images were generated using DPABI software.The voxel-wise ratio of CBF to ReHo(CBF/ReHo)was calculated as the regional NVC parameter.Differences in regional NVC characteristics were compared between patient groups and the healthy control group.Correlations between NVC parameters and SIS scores within patient groups were explored.Results(1)A total of 38 patients with MIS or TIA due to intracranial large artery moderate-to-severe stenosis or occlusion were included(26 males,12 females,aged 36-69 years,with mean age of[52±11]years),with 23 in the left-sided involvement group and 15 in the right-sided involvement group.Nineteen healthy subjects were included(10 males,9 females,aged 37-67 years,with mean age of[53±10]years).Post-hoc power analysis showed statistical power of 0.808 for comparing the left-sided involvement group with the healthy control group and 0.762 for comparing the right-sided involvement group with control group.(2)No statistically significant differences were found on gender,age,education level,or body mass index across the three groups(all P>0.05).No statistically significant differences were observed on the type of cerebrovascular event,cerebrovascular risk factors,distribution of the responsible vessel,degree of stenosis in the responsible vessel,admission NIHSS score,or laboratory test results between the two patient groups(all P>0.05).There were no statistically significant differences in the total SIS score and the scores of subscales between the two patient groups(all P>0.05).(3)Compared with the healthy control group,the left-sided involvement group exhibited reduced CBF/ReHo values in the left superior and middle temporal gyri,supramarginal gyrus,middle and inferior frontal gyri,precentral gyrus,angular gyrus,postcentral gyrus,insula,and posterior cerebellar lobe(FDR-corrected,all P<0.05).In the right-sided involvement group,reduced CBF/ReHo values were observed in the right supramarginal gyrus,right postcentral gyrus,inferior temporal gyrus,and insula(FDR-corrected,all P<0.05).(4)Correlation analysis revealed that the SIS total score in the left-sided involvement group negatively correlated with CBF/ReHo values in the right inferior frontal gyrus(T=-5.91)and the right middle temporal gyrus(T=-6.65,FDR-corrected,both P<0.05).The SIS subscale score for activities of daily living in the left-sided involvement group showed negative correlations with CBF/ReHo values in the right angular gyrus(T=-7.36),right medial superior frontal gyrus(T=-6.97),right orbitofrontal cortex(T=-8.99),and left thalamus(T=-7.51,FDR-corrected,all P<0.05).No significant correlation was observed between the SIS total score and CBF/ReHo values in patients with right-sided involvement group.The SIS subscale for communication score in the right-sided involvement group correlated with CBF/ReHo in the left lingual gyrus(T=-12.15),left olfactory cortex(T=-7.68),and right anterior cingulate and paracingulate cortex(T=-9.46,FDR-corrected,all P<0.05).Conclusions Patients with MIS or TIA due to intracranial large artery moderate-to-severe stenosis or occlusion show abnormal NVC in the acute phase,especially those with left hemisphere involvement,who exhibit more extensive impairments.QoL in left-sided involvement patients is strongly linked to NVC in the right orbitofrontal cortex and right middle temporal gyrus.These findings require further validation in larger-scale studies.
