Objective To analyze the clinical characteristics and risk factors of noninfectious fever after endovascular repair of aortic dilatation diseases, and to explore management strategies. Methods A retrospective analysis was conducted on the clinical data of patients who underwent endovascular aortic repair for aortic dilatation diseases from January 2021 to October 2023. Based on inclusion and exclusion criteria, the enrolled patients were divided into a febrile group and an afebrile group according to the presence of postoperative fever. Clinical data, including demographics and surgical details, were compared between the two groups. Multivariate logistic regression analysis was performed on indicators with P≤0.05 in the univariate analysis, and receiver operating characteristic (ROC) curves were generated to analyze the predictive value of risk factors for postoperative noninfectious fever. Results A total of 305 patients were included in the final analysis. Postoperative noninfectious fever occurred in 75.08% (229/305) of the patients, with 98.25% of cases occurring within the first two postoperative days. The febrile group (n=229) had a median age of 65.0 (IQR: 53.0, 73.0) years with 83.4% males, while the afebrile group (n=76) had a median age of 71.0 (IQR: 65.0, 76.7) years with 84.2% males. Univariate analysis showed that the age, prevalence of coronary heart disease, preoperative statin use, and prevalence of aortic aneurysm were significantly lower in the febrile group compared to the afebrile group. Logistic regression analysis indicated that age, surgical site, disease type, preoperative elevated body temperature, and stent type were significantly associated with noninfectious fever, while preoperative statin use was negatively correlated. ROC curve analysis demonstrated that age, surgical site, preoperative elevated body temperature, and stent type had significant predictive value for postoperative noninfectious fever (P<0.01). Conclusion Noninfectious fever is highly prevalent following aortic repair. The relationship between fever and infection should be comprehensively evaluated based on risk factors and changes in the patient's condition to promote the rational use of antibiotics.

Objective To explore the clinical characteristics and features of noninfectious fever in elderly patients with aortic dilation disease.Methods A total of 599 elderly patients diagnosed with aortic dilation disease(including 274 cases of acute disease and 325 cases of chronic disease)in the Affiliated Wuxi People's Hospital of Nanjing Medical University from January 2021 to June 2024 were recruited.According to their age,the patients with acute disease were divided into aged group 1(105 cases)and non-age group 1(169 cases),and those with chronic disease were into aged group 2(231 cases)and non-age group 2(94 cases).For the 520 patients(246 cases of acute disease and 274 cases of chronic disease)subjected for endovascular repair surgery,they were assigned into aged group 3(90 cases)and non-aged group 3(156 cases)for those with acute dis-ease,and aged group 4(206 cases)and non-aged group 4(68 cases)for those with chronic disease.For the 230 patients experiencing postoperative non-infectious fever,they were divided into acute-febrile(50 cases),acute-afebrile(20 cases),chronic-febrile(106 cases)and chronic-afebrile(54 cases)groups.Their general data was compared among the groups.Multivariate logistic regression analysis was conducted to identify the risk factors for postoperative noninfectious fever.ROC curve was plotted to analyze the predictive performance of our model for postoperative noninfec-tious fever.Results The surgical rate of endovascular repair surgery was 86.81％(520/599).The aged patients had significantly lower incidences of postoperative fever and non-infectious fever than the non-aged patients(P＜0.05,P＜0.01).There were no statistical differences in the ratio of using first and second generation cephalosporins or clindamycin and the duration of postopera-tive medication between the febrile group and afebrile group(P＞0.05).Multivariate logistic re-gression analysis showed that for acute disease,implantation of polytetrafluoroethylene stents(OR=7.931,95％CI:1.945-32.337,P=0.004)was a risk factor,while administration of statins(OR=0.160,95％CI:0.032-0.807,P=0.026)was a protective factor for non-infectious fever.ROC curve analysis indicated that showed our model based on above results of multivariate logis-tic regression analysis had an AUC value of 0.836,a sensitivity of 60.0％and a specificity of 95.0％.For chronic disease,implantation of polytetrafluoroethylene stents(OR=2.558,95％CI:1.250-5.235,P=0.010)and preoperative increased temperature(OR=4.615,95％CI:1.502-14.181,P=0.008)were risk factors for non-infectious fever.Based on these results,the construc-ted model obtained an AUC value of 0.714 in ROC curve analysis.Conclusion For elderly patients undergoing aortic repair surgery,it is unnecessary to upgrade the variety of antibiotics or extend the course of treatment due to advanced age.Individualized analysis of possible infections should be conducted to promote the rational use of antibiotics.

Objective To analyze the application effect of multidisciplinary collaborative nursing based on the Information-Knowledge-Attitude-Practice(IKAP)theory in patients undergoing lobectomy via thoracoscopy.Methods A total of 168 patients undergoing lobectomy via thoracoscopy were se-lected,and randomly divided into control group and observation group using a random number table,with 84 patients in each group.The control group received routine nursing,while the observation group received multidisciplinary collaborative nursing based on the IKAP theory in addition to routine nurs-ing.The postoperative recovery,pulmonary function indicators[forced vital capacity(FVC),maxi-mum voluntary ventilation(MVV)and ratio of forced expiratory volume in the first second to forced vi-tal capacity(FEV1/FVC)],self-efficacy[General Self-Efficacy Scale(GSES)score]and self-man-agement ability[Chronic Disease Self-Management Questionnaire(CDSMQ)score]before and after intervention were observed and compared between the two groups.Results The observation group had shorter first ambulation time,first flatus time and length of hospital stay compared with the control group(P＜0.05).Before intervention,there were no statistically significant differences in FVC,MVV,FEV1/FVC,CDSMQ scores and GSES scores between the two groups(P＞0.05).After inter-vention,the observation group had higher FVC,MVV,FEV1/FVC,CDSMQ scores and GSES scores compared with the control group(P＜0.05).Conclusion Multidisciplinary collaborative nursing based on the IKAP theory can effectively promote the recovery process in patients undergoing lobec-tomy via thoracoscopy,improve postoperative pulmonary function,self-management ability,and self-efficacy,thereby enhancing the quality of rehabilitation.

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 clinical and genetic variation characteristics of a child with autosomal dominant lateral temporal lobe epilepsy caused by de novo variation of the MICAL1 gene. Methods:Clinical data of the patient with autosomal dominant lateral temporal lobe epilepsy caused by MICAL1 gene variation diagnosed in Children′s Hospital of Soochow University in August 2019 were collected. The whole exome sequencing was performed on the core members of the family, and the characteristics of gene variations were analyzed. Results:The proband, a 10 years and 5 months old boy, was admitted to the hospital because of "intermittent convulsions for 7 years". The clinical manifestations included focal or generalized tonic-clonic seizures and hearing aura, with normal language and intellectual development. No abnormalities were found in the T 1 and fluid attenuated inversion recovery sequences of the cranial 3.0 T magnetic resonance imaging and 3D thin-slice magnetic resonance imaging.Long-range video electroencephalogram showed the distribution of spinous and slow spinous waves in the left frontal and temporal areas. The results of whole exome gene sequencing in the core family members showed heterozygous de novo missense variation in the MICAL1 gene of the proband (NM_022765): c.763G>T(exon6)(p.Val255Leu) that had not been reported. According to American College of Medical Genetics and Genomics and Association for Molecular Pathology guidelines (2015), the mutation was considered potentially pathogenic. The application of antiepileptic drugs was effective in controlling epileptic seizures. Conclusions:Auditory symptoms are main clinical manifestations for the child with autosomal dominant lateral temporal lobe epilepsy. Antiepileptic drugs can effectively control epileptic seizures of the child, and the MICAL1 gene c.763G>T (p.Val255Leu) mutation is the genetic cause of the proband.

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 compare the clinical efficacy of laparoscopic pelvic floor autologous fascia integral repair based on membrane anatomy versus transperineal proctosigmoidectomy (Altemeier procedure) in the treatment of patients with complete rectal prolapse (CRP).Methods:This study employed a retrospective observational cohort design. Clinical data were collected from a total of 55 CRP patients who underwent surgical treatment between January 2018 and July 2023, including 25 patients from Luoyang Central Hospital, affiliated with Zhengzhou University, and 30 patients from the 989th Hospital of the Joint Logistics Support Force & Military Anorectal Surgery Research Institute. All patients undergoing surgery met the following criteria: aged ≥ 18 years, rectal prolapse protruding outside the anus, prolapse length > 5 cm with inability to self-reduce, conforming to the diagnostic criteria for CRP, and being first-time treated patients. Twenty-seven patients who underwent the Altemeier procedure between January 2018 and March 2021 were assigned to the Altemeier group; 28 patients who underwent laparoscopic pelvic floor autologous fascia integral repair based on membrane anatomy between April 2021 and July 2023 were assigned to the integral repair group. The therapeutic efficacy differences between the two groups were analyzed and compared, including the CRP length (DCRP), Wexner Constipation Score, Wexner Fecal Incontinence Score, and Gastrointestinal Quality of Life Index (GIQLI) before surgery and at 6, 12, and 24 months after surgery, as well as postoperative complications and recurrence at 24 months after surgery.Results:There were no statistically significant differences between the two groups in terms of gender distribution, age, preoperative body mass index (BMI), defecation frequency, DCRP, Wexner Constipation Score, Wexner Fecal Incontinence Score, and GIQLI (all P>0.05). All patients completed the surgery. The length of hospital stay and intraoperative blood loss in the integral repair group were significantly less than those in the Altemeier group (both P<0.01). At 6, 12, and 24 months after surgery, the DCRP, Wexner Constipation Score, Wexner Fecal Incontinence Score, and GIQLI in both groups significantly improved compared with the preoperative values (all P<0.001). At 6, 12, and 24 months after surgery, the CRP treatment effect, Wexner Constipation Score, Wexner Fecal Incontinence Score, and GIQLI in the integral repair group were significantly better than those in the Altemeier group (χ2=15.821, P<0.001; χ2=18.238, P<0.001; χ2 = 12.558, P=0.001; and χ2 =22.413, P<0.001, respectively). In the integral repair group, 4 patients (14.3%) developed grade I-III postoperative complications, including 2 cases of urinary retention, 1 case of anastomotic bleeding, and 1 case of anastomotic stenosis. In the Altemeier group, 11 patients (40.7%) developed grade I-III postoperative complications, including 4 cases of urinary retention, 3 cases of anastomotic bleeding, 1 case of anastomotic stenosis, 2 cases of intestinal fistula, and 1 case of fecal incontinence. The difference between the two groups was statistically significant (χ2=4.850, P=0.028). There was no recurrence of CRP in the integral repair group at 24 months after surgery, while 7 cases of CRP recurrence were observed in the Altemeier group at 24 months after surgery. The difference between the two groups was statistically significant (χ2=6.148, P=0.013). Conclusion:The autologous fascia repair technique based on membrane anatomy and the pelvic floor integral theory is superior to the transperineal Altemeier procedure in the treatment of CRP. Furthermore, it is an effective surgical method for CRP.

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.
