Background: Gliomas, especially Glioblastoma multiforme, are the most frequent type of primary tumors in central nervous system. Increasing researches have revealed the relationship between autophagy and tumor, while the molecular mechanism of autophagy in glioma is still rarely reported. Objective: Our research aims to conform the autophagy-related genes (ARGs) implicated in the development and progression of glioma and improve our understanding of autophagy in glioma. Methods: 20 candidate ARGs were screened through the protein-protein interaction network. We also downloaded the publicly accessible glioma data for 665 individuals from TCGA and 970 individuals from CGGA with RNA sequences and clinicopathological information. Subsequently, univariate and multivariate Cox regression analysis identified 5 key ARGs among the 20 candidate genes as key prognostic genes for survival, GSEA and immune response analysis. Results: ATG5, BCL2L1, CASP3, CASP8, GAPDH were identified as key ARGs in our research. Further studies showed that the high-risk population was linked to a dismal prognosis and suggested an immune-inhibitory microenvironment. GSEA results demonstrated that high risk population was closely related to DNA repair, hypoxia pathways, implicated in immunosuppression and carcinogenesis. Through CMap, we finally identified 14 candidate drugs for the ARG high risk population. Conclusions: This study established and verified an ARG risk model, which can serve as an independent predictor for prognosis, reflect on the strength of the immune response and predict the potential drugs in glioma. Our findings offer new understandings of ARG molecular mechanism and promising therapeutic targets for glioma treatment.

Enhancing Spatial Awareness: The Use of Hand Gestures in Navigational Tasks
( Zijun Zhao ),( Seunghee Lee ) 한국감성과학회 2023 한국감성과학회 국제학술대회(ICES) Vol.2023 No.-
In this study, we explore the role of hand gestures in wayfinding and route memory enhancement during navigation app usage. We conducted experiments with ten participants and recorded their hand gestures as they navigated to an unfamiliar destination. We categorized the gestures into three types: finger pointing, hand horizontal movement, and palm flexion. Participants' feedback suggested that these gestures played a significant role in improving their spatial awareness and memory recall. This paper sheds light on the potential benefits of incorporating hand gestures into navigation apps for better route memorization.

Does H3K27M Mutation Impact Survival Outcome of High-Grade Spinal Cord Astrocytoma?
Fan Zhang,Lei Cheng,Ze Ding,Shengxi Wang,Xingang Zhao,Zijun Zhao,Cong Liang,Kun Wu,Dongao Zhang,Yinqian Wang,Tao Fan 대한척추신경외과학회 2023 Neurospine Vol.20 No.4
Objective: To evaluate the impact of H3K27M mutation in the prognosis of histological high-grade intramedullary astrocytoma. Methods: A total of 78 patients who were diagnosed with high-grade spinal cord astrocytoma were included. Clinical data consisting demographic, radiological, molecular features and treatment data were recorded. Univariate and multivariate Cox analysis were performed to investigate variables associated with survival outcome of histological high-grade spinal cord astrocytoma. Results: Median survival time was 21 months. Overall survival (OS) at 1 and 3 years was 65.7% and 40.7%, respectively. Sex, location, and tumor span did not present significant association with OS. Patients with H3K27M mutation showed significant shorter duration of symptom than patients with H3K27 wild-type. As respect to adjuvant treatment, adjuvant radiotherapy and chemotherapy were associated with favorable OS (both p = 0.01). Younger patients (age ≤ 18 years) had shorter OS (p = 0.008) than adult patients (age > 18 years). Of note, H3K27M mutation did not show significant impact on the survival outcome, regardless of histology grade 3 or grade 4 (p = 0.3). Conclusion: Histological high-grade spinal cord astrocytoma has dismal prognosis. Our study demonstrated that H3K27M mutation did not show significant impact on survival outcome of histological high-grade spinal cord astrocytoma.
