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.

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.

Objective To explore the influence of the chronic disease management model based on wearable devices on the self-management ability,quality of life and physiological index control of patients after percutaneous coronary intervention(PCI).Methods Eighty patients with coronary heart disease who underwent PCI in Hefei BOE Hospital from April to September 2024 were selected as research objects.They were divided into control group and intervention group according to the random number table method,with 40 cases in each group.The control group received the conventional care model,while the intervention group adopted a postoperative chronic disease management model based on wearable devices,and the intervention period was 6 months for all.The coronary artery disease self-management scale(CSMS)was used to assess self-management ability,and the Seattle angina questionnaire(SAQ)was used to assess quality of life before and after the intervention.Additionally,the compliance rates of blood pressure,low density lipoprotein-cholesterol(LDL-C),and body mass index(BMI)were recorded.Results After the intervention,the scores of each dimension and total score of CSMS,as well as the scores of each dimension of SAQ of two groups of patients were significantly higher than those before the intervention(P＜0.05).Moreover,the scores of each dimension and total score of CSMS and the scores of each dimension of SAQ of intervention group were significantly higher than those of control group(P＜0.05).The compliance rates of blood pressure,LDL-C and BMI in intervention group were significantly higher than those in control group(P＜0.05).Conclusion The chronic disease management model based on wearable devices,through data monitoring,team collaboration and dynamic intervention,can significantly enhance the self-management ability of patients after PCI,improve their quality of life and the compliance rate of key physiological indicators,and has clinical promotion value.

Objective To investigate prokaryotic expression of the antigen sequence (amino acids 59-145) of mouse leukemia-related protein 16 (LRP16) protein and preparation of rabbit anti-mouse LRP16 polyclonal antibody. Methods The prokaryotic expression plasmid pLS962-LRP16 was constructed by the molecular cloning method and transferred into E.coli Rosetta to express LRP16 protein induced by IPTG. The recombinant protein was purified using Ni-NTA affinity columns followed by gel filtration chromatography. New Zealand white rabbits were immunized with the purified antigen to generate polyclonal antiserum, with antibody titer quantified by ELISA. Antigen-specific IgG was affinity-purified using Sepharose-coupled LRP16 and validated through Western blot and immunofluorescence assays. Results SDS-PAGE analysis confirmed insoluble expression of the LRP16 fusion protein as inclusion bodies. ELISA demonstrated exceptional antiserum titer (1:256 000). Western blot and immunofluorescence verified that the polyclonal antibody could specifically recognize endogenous LRP16 in murine tissues. Conclusion The prokaryotic expression of the LRP16 gene is successfully achieved, and the rabbit anti-mouse LRP16 polyclonal antibody exhibiting high specificity is prepared. This lays the foundation for further studies on the function of the LRP16 gene.

Skeletal muscle dysfunction is a common extrapulmonary comorbidity of chronic obstructive pulmonary disease (COPD) and is associated with decreased quality-of-life and survival in patients. The autophagy lysosome pathway is one of the proteolytic systems that significantly affect skeletal muscle structure and function. Intriguingly, both promoting and inhibiting autophagy have been observed to improve COPD skeletal muscle dysfunction, yet the mechanism is unclear. This paper first reviewed the effects of macroautophagy and mitophagy on the structure and function of skeletal muscle in COPD, and then explored the mechanism of autophagy mediating the dysfunction of skeletal muscle in COPD. The results showed that macroautophagy- and mitophagy-related proteins were significantly increased in COPD skeletal muscle. Promoting macroautophagy in COPD improves myogenesis and replication capacity of muscle satellite cells, while inhibiting macroautophagy in COPD myotubes increases their diameters. Mitophagy helps to maintain mitochondrial homeostasis by removing impaired mitochondria in COPD. Autophagy is a promising target for improving COPD skeletal muscle dysfunction, and further research should be conducted to elucidate the specific mechanisms by which autophagy mediates COPD skeletal muscle dysfunction, with the aim of enhancing our understanding in this field.
