Objective To investigate the changes of non-motor symptoms and quality of life in patients with Parkinson's disease (PD) after bilateral subthalamic nucleus deep brain stimulation (STN-DBS). Methods Questionnaires were conducted among a convenience sample of 45 PD patients who met the indications of STN-DBS in the Functional Neurosurgery Center of Ruijin Hospital,Shanghai JiaoTong University School of Medicine in Shanghai from June 1,2020 to August 31,2020.The Non-motor Symptom Scale (NMSS) and 8-item Parkinson's Disease Questionnaire (PDQ-8) were used to evaluate the patients' non-motor symptoms and quality of life preoperatively and at 3,6,12 and 24-month postoperative visits. Results Generalized estimation equation analysis showed a significant overall change of PDQ-8 and levodopa equivalent daily dose (LEDD) over five follow-up visits ( P＜0.05).Sleep/fatigue,Mood/apathy,Attention/memory,Gastrointestinal,Urinary,Sexual function and Miscellaneous subscores showed a statistically significant decreasing trend ( P＜0.05),while Cardiovascular and Perceptual subscores of NMSS were unchanged ( P>0.05). Conclusion Bilateral STN-DBS has a long-term benefit on sleep/fatigue and urinary symptoms and a short-term benefit on Sleep/fatigue,Mood/apathy,Attention/memory,Gastrointestinal,Urinary,Sexual function and Miscellaneous symptoms in PD patients.Moreover,it can reduce the medication intake and improve the patients' quality of life.

Objective To analyze the occurrence of second primary malignancies (SPM) in patients with glioma and identify their risk factors. Methods Cases of glioma patients diagnosed from January 2000 to December 2021 were collected from the Surveillance,Epidemiology,and End Results (SEER) database.A retrospective analysis was performed on patients' demographic characteristics,clinical features,and SPM occurrence,using univariate and multivariate Cox regression analysis to identify risk factors. Results A total of 87,889 glioma patients were screened from the SEER database,with 1,043 developing SPM.The median overall survival (OS) for patients with SPM was 105.0 months.The most common sites for SPMs were the breast (34.08%),lung and bronchi (11.27%),and thyroid (10.99%).Multivariate Cox regression analysis showed that age (≥65 years:HR=3.047,95% CI:2.570~3.613, P＜0.001),pathology (glioblastoma:HR=2.091,95% CI:1.793~2.438, P＜0.001),and radiotherapy (HR=1.489,95% CI:1.276~1.736, P＜0.001) were independent risk factors for the occurrence of SPM. Conclusion Breast,lung and bronchi,and thyroid are the most common sites of SPM in glioma patients.Age,pathology,and radiotherapy are significant risk factors for SPM occurrence.Identifying these risk factors can guide personalized follow-up and screening for SPM in glioma patients.

Objective To study the distribution characteristics of cerebral blood vessels in mice and the spatial relationship with adjacent nerve cells using fast three-dimensional microscopic imaging technology. Methods The adult Tie2-Cre::Ai9 hybrid transgenicmice(C57BL/6) with fluorescent protein labeled vascular endothelial cells were perfused with 4% paraformaldehyde in the heart to obtain complete brain tissue,clearing tissue,andstained the nerve cells of the whole brain.The rapid three-dimensional imaging system (VISoR) was used to obtain the microscopic images of the whole brain vessels and nerve cells in mice with 1×1×3.5 μm ³ voxel resolution,and the two-dimensional image sequence was reconstructed into a three-dimensional whole brain image.Part of cortex,hippocampus and thalamus were selected to segment and extract blood vessels and analyze their morphological characteristics;Automatically identify nerve cells and quantitatively analyze the distribution characteristics of the distance between nerve cells and the nearest blood vessels. Results The three-dimensional images of the distribution of blood vessels and nerve cells in the whole brain of mice were successfully collected.The whole brain view of C57BL/6 mouse's complex vascular network was provided through high-resolution brain atlas.The analysis showed that the density of bifurcation points and the volume fraction of blood vessels in hippocampus were smaller than those in cortex and thalamus,and the difference was statistically significant.The staining of neurons with Nissl stain showed that there were differences in the distribution of blood vessels and nerve cells in different brain regions.In the regions of interest of different brain regions,the distance between neurons and blood vessels was counted,and the results were statistically different. Conclusion The whole brain vessels and neurons of mice can be imaged by fast 3D microscopic imaging technology.Through the quantitative analysis of regional blood vessels and nerves,it was found that there were regional distribution characteristics between blood vessels and nerves in mice.

Objective To investigate the expression changes of GLDN (Gliomedin) in glioblastoma (GBM) tissues and cell lines,and its impact on patient prognosis. Methods By conducting further mining and analysis of sequencing data from previously published studies on glioblastoma multiforme (GBM) drug resistance within our research group,we downloaded the GSE113510 mRNA sequencing data from the international GEO database,GLDN was identified as the gene with the most significant differential expression.The expression differences of GLDN between primary and recurrent GBM tissues were analyzed using the CGGA database.GLDN mRNA levels in GBM cell lines were measured by quantitative real-time PCR,and protein levels were detected by Western blotting.Survival analysis using the CGGA and TCGA databases was conducted to examine the relationship between GLDN expression and patient prognosis. Results Analysis of the GSE113510 dataset revealed that GLDN exhibited the most significant differential expression in drug-resistant GBM cell lines.GLDN expression was significantly higher in recurrent GBM tissues compared to primary GBM tissues ( P＜0.05).Additionally,GLDN expression was markedly elevated in drug-resistant cell lines 229R,251R,and HG7R compared to their non-resistant counterparts ( P＜0.05).Survival analysis showed that high GLDN expression was associated with poorer patient prognosis,with a significantly shorter survival time. Conclusion GLDN is highly expressed in glioblastoma and is closely associated with drug resistance and poor prognosis.It may serve as a potential therapeutic target in GBM treatment.

Objective To investigate the important factors affecting the early prognosis of patients over 75 years old after embolization of ruptured intracranial aneurysm. Methods A retrospective collection of 78 patients with intracranial aneurysm who were admitted to the Department of Neurosurgery of Xiamen Third Hospital from January 2016 to January 2022,all cases were over 75 years old,and relevant clinical data of embolization treatment,including gender,Weight,smoking history,hypertension,diabetes,hyperlipidemia,atrial fibrillation,cerebrovascular disease history,aneurysm location,Hunt-Hess classification,WFNSS classification,CT Fisher classification,etc.The prognosis results were divided into a good outcome group (mRS grade I-II) and a poor outcome group (mRS grade III-V) using the modified Rankin scale (mRS) scale.Statistical analysis of clinical data,screening of independent risk factors that affect the poor prognosis of patients. Results Tatistical univariate analysis showed that,compared with the good prognosis group,the higher the GCS grade,WFNSS grade and Hunt-Hess grade of the poor prognosis group,the worse the relative prognosis,and the difference was statistically significant ( P＜0.05).Logistic regression analysis showed that GCS classification (OR=1.024,95%CI:0.214~4.914, P=0.976),WFNSS classification (OR=9.021,95%CI:2.557~31.824, P=0.001) and Hunt-Hess classification (OR=6.848,95%CI:1.435~32.682, P=0.016) was a prognostic factor.ROC curve analysis showed that the combination of Hunt-Hess classification and WFNSS classification could be used as an important influencing factor for neurological recovery (AUC=0.855),When taking the best cut-off point,the sensitivity was 89.6% and the specificity was 70.0%. Conclusion For the short-term prognosis of ruptured intracranial aneurysm interventional embolization in people over 75 years old,the combination of Hunt-Hess classification and WFNSS classification is more valuable than other factors.
