Aging plays a significant role in the onset and progression of many diseases, yet it remains understudied in the context of intracranial aneurysms. The aim of this study is to investigate the role of aging-related genes in the development of intracranial aneurysms using public databases, in order to understand the underlying biological mechanisms.  METHODS: Gene expression profiles for intracranial aneurysms were downloaded from the GEO database. Human aging-related genes were obtained from the HAGR website. Differentially expressed gene analysis and WGCNA were used to identify core hub genes. GO and KEGG enrichment analyses were conducted to determine the potential biological functions and pathways that these differentially expressed aging-related genes in intracranial aneurysms might be involved in. Based on the hub genes, co-expression gene networks and Gene-TF-miRNA regulatory networks were constructed. Further exploration of drug-gene interactions was conducted to screen potential target drugs.</p><p><strong>Results: </strong>Through the intersection of aging-related genes and differentially expressed genes in IA, 32 common differentially expressed genes were identified, with 20 genes upregulated and 12 genes downregulated. GO enrichment analysis showed that these genes were mainly involved in epithelial cell proliferation and regulation, peptide enzyme activity modulation, and metabolic Homeostasis. KEGG enrichment analysis showed that these genes were primarily involved in the adipocytokine signaling pathway, growth Hormone synthesis,secretion and action, neurotrophin signaling pathway, and longevity regulating pathway. WGCNA was used to identify genes highly correlated with the IA phenotype, and an intersection with the 32 differentially expressed aging-related genes yielded 11 candidate Hub DEARGs. The expression of the candidate Hub DEARGs was validated using an external dataset, ultimately confirming 4 hub DEARGs related to intracranial aneurysms. Among them, NGFR and ADCY5 were downregulated, while BUB1B and SERPINE1 were upregulated.  CONCLUSIONS: This study identified four aging-related genes, NGFR, ADCY5, SERPINE1, and BUB1B, that are associated with intracranial aneurysms. This provides new insights into the molecular mechanisms underlying the development of intracranial aneurysms. The identified core genes provide promising leads for further experimental research to explore the pathogenesis of the disease.</p>","PeriodicalId":36700,"journal":{"name":"Chinese Neurosurgical Journal","volume":"11 1","pages":"22"},"PeriodicalIF":0.0,"publicationDate":"2025-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12502511/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145239917","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the product has some shortcomings, as it is not entirely biodegradable, the lower disc's angle cannot be adjusted, and there is a failure to readjust after fixation. To address these issues, MedArt Technology Co., Ltd. from China has come up with a high-purity PLLA combined with an innovative structural design to develop a novel cranial flap fixation system that is more convenient to operate, has a better resetting effect, and can be fully absorbed.

Traditional classifications of hydrocephalus do not incorporate management strategies (not classified according to the degree of difficulty of treatment). Clinically, hydrocephalus that is challenging to treat is often categorized as refractory hydrocephalus (RH). However, the absence of a unified definition of RH impedes the standardization of treatment approaches, raising clinical dilemmas. This article explores the definition, etiologies, classification, and management strategies for RH. Based on the literature and the Diagnosis-Related Group payment system principles, RH is clinically defined as progressive hydrocephalus meeting one or more of the following criteria: (1) the absence of significant clinical or radiological improvement within 60 days despite standard interventions, usually due to pathological factors, such as abnormal CSF characteristics, (2) inability to achieve curative surgical treatments attributable to complex anatomy such as abnormal dynamic changes or multiloculated compartments, and (3) failure to respond after two consecutive therapeutic procedures. RH consists of six distinct subtypes, with infectious hydrocephalus being the most common, followed by low-pressure hydrocephalus. Temporary management strategies for RH must be carefully tailored to patient-specific characteristics, considering the risk-benefit analysis of available measures. In cases of infectious RH, achieving CSF sterilization and evaluating the results are crucial. Curative surgery for infectious RH should be performed only after CSF has been completely sterilized to normal levels.
