Objective:To explore the benefits of transradial diagnostic cerebral angiography in elderly patients and its correlation with morphometric parameters of the aortic arch.Methods:Clinical data and aortic arch CTA imaging parameters of patients who underwent cerebral angiography at the Department of Neurosurgery, Beijing Hospital, between May 2022 and April 2023 were retrospectively analyzed.The study aimed to compare the time taken for angiography via radial artery access in elderly patients versus younger patients, as well as via femoral artery access, and to evaluate the associated aortic arch morphology parameters.Results:A total of 101 patients' data were analyzed, with 67 males(66.3%)and an average age of 63.4±12.0 years.Among them, 69 patients(68.3%)were aged 60 and above.The arterial approach for 44 patients(43.6%)was radial, while 57 cases(56.4%)used the femoral artery approach.In the elderly group, 14 cases(20.6%), 31 cases(45.6%), and 23 cases(33.8%)had type Ⅲ aortic arch, respectively.For younger patients, 17 cases(53.1%), 12 cases(37.5%), and 3 cases(9.4%)fell into these categories.The distribution difference was statistically significant( χ2=12.765, P=0.002).Elderly patients had a larger aortic arch width angle compared to younger patients(106°±12°and 100°±12°, t=2.334, P=0.022).The time for whole-brain angiography via radial artery was shorter for elderly patients than via femoral artery(39.8±29.5 minutes and 52.2±28.4 minutes, respectively, t=1.845, P=0.070).In young patients, there was no significant time difference between the two approaches(42.3±30.4 minutes for radial artery and 34.6±11.2 minutes for femoral artery, t=1.026, P=0.313).In the type Ⅱ aortic arch group, the average times for transradial and transfemoral approaches were 38.1±21.7 minutes and 46.7±32.2 minutes, respectively( t=1.020, P=0.314).The average times for the type Ⅲ aortic arch group were 41.9±37.3 minutes and 48.9±20.7 minutes, respectively.Correlation analysis revealed a significant negative correlation between the duration of radial artery access and the distance from the origin of the innominate artery to the left subclavian artery(Pearson correlation coefficien( r=-0.372, P=0.014). Conclusions:In elderly patients, particularly those with type Ⅱ or Ⅲ aortic arch or a wide aortic arch, diagnostic cerebral angiography using transradial access is preferable to femoral access.The distance between the innominate artery and the left subclavian artery origin could impact the duration of the procedure.

Objective:To examine the clinical effect of endovascular treatment for patients with non-acute symptomatic anterior circulation distal medium artery disease (aDMAD).Methods:This is a retrospective case series study.Retrospective analysis was conducted on the clinical data of 28 patients(29 lesions) with non-acute symptomatic aDMAD who underwent endovascular treatment at the Department of Neurosurgery,Beijing Hospital from May 2018 to March 2024. There were 15 males and 13 females,with an age of (63.4±10.2) years (range:36 to 82 years). The course of disease were more than 72 hours of all the patients. Confirmed by digital subtraction angiography,the lesion was located in distal anterior circulation and (or) medium arteries. Among them, 21 lesions (72.4%) located at middle cerebral artery and 8 lesions (27.6%) located at anterior cerebral artery.The median degree of stenosis before surgery ( M(IQR)) was 90%(23%) (range:70% to 100%).After standardized drug treatment,there was still a transient ischemic attack or cerebral infarction in the vascular related area.The therapeutic effects and complications were analyzed,and the differences in the occurrence of target vessel restenosis under different interventional treatment methods were collected. Results:A total of 28 patients with 29 lesions underwent endovascular treatment, with a treatment success rate of 96.6% (28/29). The course of disease was 60(66)days (range:9 to 210 days). Simple plain balloon angioplasty was performed in 12 cases (13 lesions), drug-coated balloon (DCB) angioplasty in 7 cases (7 lesions), and stent placement in 9 cases (9 lesions). The median degree of stenosis after surgery was 20%(39%) (range:0 to 50%). There was no new cerebral infarctions,cerebral hemorrhages,or other complications during the perioperative period.Imaging follow-up was conducted on 23 lesions for 12(15)months(range:3 to 34 months),with 10 cases (43.5%) of restenosis,3 cases (13.0%) of symptomatic restenosis,and 4 cases (17.4%) of re-treatment. There were no new cases of cerebral hemorrhage or death during the follow-up process.The restenosis rate was 6/10 for the conventional balloon group,1/6 for the DCB group, and 3/7 for the stent group; the rate of symptomatic restenosis was 1/10 for the conventional balloon group,0/6 for the DCB group, and 2/7 for the stent group.Conclusions:Endovascular treatment for non-acute symptomatic aDMAD is relatively effective,but there is a high rate of restenosis postoperatively. DCB may reduce the occurrence of postoperative restenosis.

BackgroundPatients demonstrating depressive disorder with psychotic symptoms often have increased risk of death and poor prognosis. A large amount of research has explored the factors influencing psychotic symptoms in adult patients with depressive disorder， but few has focused on adolescent patients. ObjectiveTo explore the influencing factors of psychotic symptoms in adolescent patients with depressive disorder， so as to provide references for early screening and intervention in clinic. MethodsA total of 96 adolescent patients who met the Diagnostic and Statistical Manual of Mental Disorders， fifth edition （DSM-5） for depressive disorder and were seen in the psychiatry departments of Chaohu Hospital of Anhui Medical University and The Fourth People's Hospital of Hefei from September 2022 to January 2023 were included. Another 56 healthy individuals from the health examination center of Chaohu Hospital of Anhui Medical University were concurrently recruited as control group. Patients were assigned into psychotic group （n=32） and non-psychotic group （n=64） according to the presence or absence of psychotic symptoms. Hamilton Depression Scale-24 item （HAMD-24）， Positive and Negative Syndrome Scale （PANSS）， Positive and Negative Suicide Ideation （PANSI） and Childhood Trauma Questionnaire-Short Form （CTQ-SF） were used for evaluation. Plasma brain-derived neurotrophic factor （BDNF） concentration was obtained using Meso Scale Discovery electrochemiluminescence assay. Pearson and Spearman correlation analysis were adopted to determine the correlation of PANSS positive symptom subscale score with plasma BDNF concentration and clinical characteristics of adolescent depression patients with psychotic symptoms. Binary Logistic regression analysis was used to identify the factors influencing the presence of psychotic symptoms in adolescent patients with depressive disorder， and multiple linear regression analysis was utilized to screen the factors affecting the severity of psychotic symptoms. ResultsThe plasma BDNF concentration of adolescent patients with depressive disorder was lower than that of control group （t=-3.080， P<0.01）.The plasma BDNF concentration of psychotic group was lower than that of non-psychotic group （t=2.418， P<0.05）， while the body mass index （BMI） PANSI scores， CTQ-SF scores and HAMD-24 total scores were all higher than those of non-psychotic group （t=-2.024， -2.530， -2.187， -4.977， P<0.05 or 0.01）. Correlation analysis showed that PANSS positive symptom subscale scores were negatively correlated with anxiety/somatization factor score and weight factor score in HAMD-24 of psychotic group （r=-0.438， -0.498， P<0.05 or 0.01）. Binary Logistic regression showed that BMI， plasma BDNF concentration， HAMD-24 total scores and cognitive dysfunction factor score were the influencing factors of psychotic symptoms in adolescent patients with depressive disorder. Multiple linear regression analysis demonstrated that weight factor scores （β=-0.349， P<0.05） and anxiety/somatization factor score （β=-0.433， P<0.05） in HAMD-24 were the factors influencing the severity of psychotic symptoms. ConclusionHigh BMI， low plasma BDNF concentration， severe depressive symptoms and cognitive dysfunction may be the risk factors of psychotic symptoms in adolescent patients with depressive disorder， furthermore， BMI and anxiety symptoms are found to be associated with the severity of psychotic symptoms. ［Funded by Scientific Research Fund Project of Anhui Institute of Translational Medicine （number， 2022zhyx-B01）； Central Finance Supported Provincial Key Clinical Specialty Construction Project of Anhui Province in 2019］

Objective:To explore the correlation among childhood trauma, obsessive-compulsive symptoms, and implicit and explicit memory in patients with obsessive-compulsive disorder(OCD).Methods:Fifty-two OCD patients were enrolled, and the childhood trauma was investigated by using the childhood trauma questionnaire short-form(CTQ-SF). The degree of obsessive-compulsive symptoms was assessed by using the Yale-Brown obsessive symptoms scale (Y-BOCS). In addition, the abilities of implicit memory and explicit memory were tested by vocabulary perception speed tasks and vocabulary recognition tasks.According to the scores of CTQ-SF, the patients were divided into abuse group( n=26) and neglect group( n=26). SPSS 22.0 software was used for t-test and Pearson correlation analysis. Results:Results of obsessive-compulsive symptoms, implicit memory, and explicit memory showed no differences between the abuse group and the neglect group( t=-1.959-1.839, P>0.05). The scores of obsessions symptoms(12.52±4.61) were positively correlated with the total scores of CTQ-SF (40.10±10.20)( r=0.331, P<0.05). On the subscale, the scores of obsessions were positively correlated with the scores of physical abuse(7.89±3.02), sexual abuse(6.47±2.28)( r=0.373, P<0.01, r=0.356, P<0.05). There was a negative correlation between the scores of physical abuse and the accuracy of explicit memory(68.75±13.33)( r=-0.281, P<0.05). The scores of physical neglect(8.98±2.67) was positively correlated with implicit memory response time(4 285.94±2 067.42)( r=0.314, P<0.05). Conclusion:Obsessions in patients with OCD are related to traumatic childhood experiences, especially physical abuse and sexual abuse.Physical trauma may influence the level of implicit and explicit memory in patients with OCD.

ObjectiveTo analyze the coping style and its relationship with anxiety status among middle school students aged 13 to 18 in Anhui province during the COVID-19 epidemic. MethodsFrom February 13 to 19， 2020， a cross-sectional survey was conducted among middle school students in Anhui province by using convenience sampling method and network questionnaire. The assessment tools included the Coping Style Scale for Middle School Students （CSSMSS） and the Screen for Child Anxiety Related Emotional Disorders （SCARED）. ResultsThe results of the CSSMSS evaluation showed that female students scored higher in emotion abreaction than male students ［（8.27±2.98） vs. （7.84±2.91）］. The scores of tolerance ［（9.74±2.73） vs. （9.11±2.60）］， escape ［（7.82±2.79） vs. （7.26±2.44）］， emotion abreaction ［（8.48±2.97） vs. （7.91±2.93）］ and fantasy/denial ［（9.79±3.56） vs. （9.26±3.47）］ of senior high school students were higher than those of junior high school students， and the score of problem solving ［（19.38±4.07） vs. （20.33±4.54）］ was lower than that of junior high school students， with statistical significance （P<0.05 or 0.01）. Correlation analysis results showed that the scores of tolerance， escape， emotion abreaction and fantasy/deny in CSSMSS were positively correlated with the scores of SCARED of middle school students in Anhui province （r=0.348， 0.287， 0.390， 0.501， P<0.01）. ConclusionDuring COVID-19 epidemic， students of different genders and grades in Anhui province have different coping styles， and some coping styles may induce anxiety status.

Objective:To investigate the feasibility and safety of endovascular recanalization for symptomatic non-acute intracranial arterial occlusion (NAICO).Methods:Twenty-five consecutive patients who underwent endovascular recanalization for NAICO between January 2017 and October 2019 at Department of Neurosurgery, Beijing Hospital were retrospectively reviewed.There were 20 males and 5 females, aged (60.5±11.0) years (range: 41 to 73 years).The preoperative modified Rankin score( M( Q R)) was 2 (2.5)(range: 1 to 5).The occlusion time was 40 (54)days (range: 17 to 570 days).The demographic data were collected. The initial procedural results, including the rate of successful recanalization, periprocedural complications and data pertaining to angiographic and clinical follow-up were recorded. Results:Recanalization was successful in 20 of 27 occlusive lesions of 25 patients. Intraoperative complications occurred in 3 cases, including vascular perforation in 1 case, arterial dissection in 1 case, and perforator occlusion occurred in 1 case. The incidence of permanent complications was 3.7% (1/27). All 25 patients underwent clinical follow-up, with a median period of 8 months (range: 1 to 33 months), and 23 patients with improved or stable modified Rankin scale. One patient developed new ischemic symptoms 2 months after discharge, and 1 patient died of complications of bed rest.The results of the angiography follow-up (median 4 months, range: 2 days to 9 months) showed that reocclusion occurred in 5 of all 20 successfully recanalized patients.Conclusions:Endovascular recanalization for symptomatic NAICO is feasible, relatively safe, and efficacious in highly selected cases. However, further larger scale pilot studies are needed to determine the efficacy and long-term outcome associated with this treatment.

Objective:To explore the safety and short-term efficacy of drug-coated balloon (DCB) angioplasty for patients with symptomatic intracranial vertebrobasilar artery stenosis.Methods:Sixteen patients with symptomatic intracranial vertebrobasilar artery stenosis who received DCB angioplasty from September 2018 to December 2019 at Department of Neurosurgery, Beijing Hospital were retrospectively reviewed. There were 15 males and 1 female, aged (63.1±9.2) years (range: 48 to 77 years). Patients′ demographics, lesions characteristics, complications, clinical and imaging follow-up data were collected and analyzed.Results:A total of 19 symptomatic intracranial vertebrobasilar artery stenosis were successfully treated with DCB.The degree of stenosis of lesion was 75% (20%) ( M( Q R)) before operation and 0 (20%) after operation. One posterior circulation stroke due to perforator artery occlusion happened in peri-procedural period.With a mean imaging follow-up time of 5.5 months, there was no restenosis occurred. Within a mean clinical follow-up period of 6.3 months, no new symptoms happened. Conclusion:For patients with symptomatic intracranial vertebrobasilar artery stenosis, DCB angioplasty seems relatively high safety with satisfactory short-term clinical and imaging outcomes.
