Background:Lipid accumulation Products(LAP) is a novel indicator of obesity. Migraine is a debilitating neurological disorder associated with severe pain. The relationship between LAP and migraine is unclear. This study used the National Health and Nutrition Examination Survey (NHANES) database from 1999-2004 to explore the relationship between Lipid accumulation products and migraine. Methods: This study used data from adults in NHANES from 1999 to 2004 for analysis. Logistic multiple regression analysis and restricted cubic spline (RCS) models were used in the study to elucidate the relationship between LAP and migraine. Subgroup analyses and sensitivity analyses were performed to validate the results. Results: Eventually 5660 participants entered the final analysis. 1129 (19.9%) cases reported having migraine or severe headaches. Based on the results of weighted Logistic analyses, a nonlinear relationship of type U between LAP and migraine was observed. When LAP was used as a continuous variable, its ratio OR= 1.001, 95% CI: 1 to 1.002, p = 0.191. LAP tertiles were grouped. Both the T1 group with lower LAP (OR = 1.16, 95% CI: 1.02-1.29, p = 0.011) and the T3 group with higher LAP (OR = 1.29, 95% CI: 1.12-1.59, p = 0.008) had a higher incidence of migraines compared to the medium group(T2). Results remained stable in models adjusted for multiple covariates. Conclusion: The study demonstrated a U-shaped like non-linear relationship between LAP and the occurrence of migraine.Lower and higher LAP were positively associated with elevated migraine occurrence. These findings are noteworthy for migraine prevention.

PURPOSE:Gliomas are aggressive CNS tumors with significant heterogeneity, posing challenges for effective treatment. This study aims to enhance glioma classification by integrating multi-omics data, including genomics and magnetic resonance imaging (MRI)-based radiomics, focusing on metabolic and immune subtypes. METHODS:Transcriptome data from 1,720 patients with glioma were analyzed to identify key prognostic factors, including 42 metabolism-related genes and 25 immune cells. A metabolism-immune classifier was developed to categorize gliomas into four subgroups: Metabolismhigh/tumor microenvironment (TME)high, Metabolismlow/TMEhigh, Metabolismhigh/TMElow, and Metabolismlow/TMElow. Multicohort MRI radiomics combined with machine learning algorithms were used to predict these subtypes. Single-cell RNA and spatial transcriptome sequencing were used to validate subgroups' metabolic and immunological characterization. RESULTS:The Metabolismlow/TMElow subgroup showed the best prognosis, whereas the Metabolismhigh/TMEhigh subgroup had the worst. Machine learning models can predict glioma subtypes noninvasively based on MRI radiomics. Single-cell RNA sequencing confirmed the distinct metabolic and immune profiles of the glioma subgroups, revealing significant cellular heterogeneity within the TME. CONCLUSION:This study demonstrates that integrating multi-omics data with MRI radiomics provides a robust framework for glioma classification, enabling more precise and personalized treatment strategies. The findings highlight the critical role of metabolic and immune profiling in understanding glioma heterogeneity and improving clinical outcomes.

Background:Desmoplastic infantile astrocytomas/ganglioglioma (DIA/DIG) arising in the suprasellar region are extremely rare, and their clinical features, optimal management, and outcomes remain unclear. We aimed to summarize the clinical manifestations, treatment strategies, and prognosis of this rare tumor entity. Patients and methods:This retrospective case series included 5 institutional cases and 13 literature cases of suprasellar DIA/DIGs. The clinical and radiological characteristics, therapies, and outcomes of this rare tumor were examined. Results:Our case series comprised 2 males and 3 females, with a median age of 6 months. Three patients underwent partial resection, and 2 had subtotal resection. During follow-up, the residual tumors in 2 patients showed spontaneous regression, 1 tumor progressed, and 2 remained stable. The literature review, including our cases, yielded 18 suprasellar DIA/DIG. Of these, 10 were male and 8 were female, with a median age of 4 months (range, 1-85 months). Ten patients had solitary suprasellar tumors and 8 had multifocal lesions. Over a median follow-up of 25 months, tumor progression of the suprasellar lesions was seen in 9 patients. Notably, spontaneous regression of the suprasellar tumors occurred in 2 patients. Conclusions:Despite being WHO grade I, suprasellar DIA/DIG can demonstrate multifocal CNS disease and high risk of progression after subtotal resection. DIA/DIG should be considered in the differential diagnosis of suprasellar lesions in infants and long-term close monitoring is warranted.

ABSTRACT Surgical intervention is vital for treating neural system tumors, with precise intraoperative determination of tumor boundaries crucial for safe and effective surgery. Optical coherence tomography (OCT), offering noninvasive, real‐time imaging, presents a promising solution. This study developed a swept‐source OCT system using a 1310 nm wavelength laser, enhanced by microelectromechanical systems technology for improved scanning accuracy. Neural tumor specimens and peritumoral tissues were analyzed, alongside evaluations in animal models, including rats and mice with gliomas, schwannomas, and meningiomas, to assess the system's real‐time surgical application. Results revealed significantly lower light attenuation in human glioma samples than in peritumoral tissues (p = 0.019), with an receiver operating characteristic curve area under the curve of 0.846. Gliomas exhibited higher pixel values and gentler trend line slopes (p < 0.001). Animal models showed the OCT system was capable of detecting nerves and their epineurium located deep to schwannomas and meningiomas (at depths <3 mm), which appeared as thin, tubular, or crescent‐shaped images with higher density compared with the surrounding tissue. These findings highlight the OCT system's ability to differentiate tumor from nontumoral tissues, demonstrating its potential as a handheld tool for precise boundary detection in neurosurgery. This advancement represents a promising step toward improving the accuracy of tumor resection.

Mutations in isocitrate dehydrogenase (IDH) are important markers of glioma prognosis. However, few studies have examined the gene expression regulatory network (GRN) in IDH-mutant and wild-type gliomas. In this study, single-cell RNA sequencing and spatial transcriptome sequencing were used to analyze the GRN of cell subsets in patients with IDH-mutant and wild-type gliomas. Through gene transcriptional regulation analysis, we identified the M4 module, whose transcription factor activity is highly expressed in IDH wild-type gliomas compared to IDH-mutants. Enrichment analysis revealed that these genes were predominantly expressed in microglia and macrophages, with significant enrichment in interferon-related signaling pathways. Interferon regulatory factor 7 (IRF7), a transcription factor within this pathway, showed the highest percentage of enrichment and was primarily localized in the core region of wild-type IDH tumors. A machine-learning prognostic model identified novel subgroups within the wild-type IDH population. Additionally, IRF7 was shown to promote the proliferation and migration of T98G and U251 cells in vitro, and its knockdown affected glioma cell proliferation in vivo. This study systematically established the regulatory mechanism of IDH transcriptional activity in gliomas at the single-cell level and drew a corresponding cell map. The study presents a transcriptional regulatory activity map for IDH wild-type gliomas, involving single-cell RNA sequencing and spatial transcriptomics to identify gene regulatory networks, machine learning models for IDH subtyping, and experimental validation, highlighting the role of IRF7 in glioma progression.

In central nervous system (CNS) surgery, the accurate identification of tumor boundaries, achieving complete resection of the tumor, and safeguarding healthy brain tissue remain paramount challenges. Despite the expertise of neurosurgeons, the infiltrative nature of the tumors into the surrounding brain tissue often hampers intraoperative differentiation between tumorous and non-tumorous tissue, thus hindering total tumor removal. Optical coherence tomography (OCT), with its unique advantages of high-resolution imaging, efficient image acquisition, real-time intraoperative detection, and radiation-free and noninvasive properties, offers accurate diagnostic capabilities and invaluable intraoperative guidance for minimally invasive CNS tumor diagnosis and treatment. Various OCT systems have been employed in neurological tumor research, including polarization-sensitive OCT systems, orthogonal polarization OCT systems, Doppler OCT systems, and OCT angiography systems. In addition, OCT-based diagnostic and therapeutic techniques have been explored for the surgical resection of CNS tumors. This review aims to compile and evaluate the research progress surrounding the principles of OCT systems and their applications in CNS tumors, providing insights into potential future research avenues and clinical applications.

Background: Cytokines are potent molecules of the immune response. They act at the site of inflammation and circulate in the bloodstream. However, there are few studies on encephalitis and circulating inflammatory proteins. Methods: In this study, Mendelian randomization (MR) was used to explore the potential causal effect of 91 circulating inflammatory proteins on 3 different types of encephalitis. Causal effects were examined using Steiger, MR-Egger, weighted median, and inverse variance weighting (IVW) methods. IVW methods were primarily used for results interpretation. In addition, sensitivity analyses were performed, including assessment of heterogeneity, horizontal pleiotropy, and Leave-one-out techniques. Results: We subjected 91 circulating inflammatory proteins to MR analysis of causality with each of the three types of encephalitis. The results suggested that the inflammatory factors with a potential causal relationship with viral encephalitis were caspase 8, C-X-C motif chemokine 6, interleukin-10, interleukin-15 receptor subunit alpha, interleukin-7, and TNF-beta. Inflammatory factors potentially causally associated with acute disseminated encephalomyelitis are beta-nerve growth factor, cystatin D, interleukin-7, Latency-associated peptide transforming growth factor beta 1,and neurotrophin-3.Inflammatory factors potentially causally associated with autoimmune encephalitis are C-C motif chemokine 25, hepatocyte growth factor, latency-associated peptide transforming growth factor beta 1, programmed cell death 1 ligand 1, sulfotransferase 1A1, and tumor necrosis factor. Conclusion: This finding identifies potential causal effects of certain circulating inflammatory factors on susceptibility to three types of encephalitis. It also suggests the therapeutic potential of modulating the levels of these cytokines. A basis for further research is provided.

BackgroundAging is an important factor in the development of Alzheimer’s disease (AD). The senescent cells can be recognized and removed by NK cells. However, NK cell function is gradually inactivated with age. Therefore, this study used senescence as an entry point to investigate how NK cells affect AD.MethodsThe study validated the correlation between cognition and aging through a prospective cohort of the National Health and Nutrition Examination Survey database. A cellular trajectory analysis of the aging population was performed using single-cell nuclear transcriptome sequencing data from patients with AD and different ages. The genome-wide association study (GWAS) cohort of AD patients was used as the outcome event, and the expression quantitative trait locus was used as an instrumental variable. Causal associations between genes and AD were analyzed by bidirectional Mendelian randomization (MR) and co-localization. Finally, clinical cohorts were constructed to validate the expression of key genes.ResultsA correlation between cognition and aging was demonstrated using 2,171 older adults over 60 years of age. Gene regulation analysis revealed that most of the highly active transcription factors were concentrated in the NK cell subpopulation of AD. NK cell trajectories were constructed for different age populations. MR and co-localization analyses revealed that CHD6 may be one of the factors influencing AD.ConclusionWe explored different levels of AD and aging from population cohorts, single-cell data, and GWAS cohorts and found that there may be some correlations of NK cells between aging and AD. It also provides some basis for potential causation.

Hydrocephalus is one of the most common brain disorders and a life-long incurable condition. An empirical "one-size-fits-all" approach of cerebrospinal fluid (CSF) shunting remains the mainstay of hydrocephalus treatment and effective pharmacotherapy options are currently lacking. Macrophage-mediated ChP inflammation and CSF hypersecretion have recently been identified as a significant discovery in the pathogenesis of hydrocephalus. In this study, a pioneering DNA nano-drug (TSOs) is developed by modifying S2 ssDNA and S4 ssDNA with SPAK ASO and OSR1 ASO in tetrahedral framework nucleic acids (tFNAs) and synthesis via a one-pot annealing procedure. This construct can significantly knockdown the expression of SPAK and OSR1, along with their downstream ion channel proteins in ChP epithelial cells, thereby leading to a decrease in CSF secretion. Moreover, these findings indicate that TSOs effectively inhibit the M0 to M1 phenotypic switch of ChP macrophages via the MAPK pathways, thus mitigating the cytokine storm. In in vivo post-hemorrhagic hydrocephalus (PHH) models, TSOs significantly reduce CSF secretion rates, alleviate ChP inflammation, and prevent the onset of hydrocephalus. These compelling results highlight the potential of TSOs as a promising therapeutic option for managing hydrocephalus, with significant applications in the future.

INTRODUCTION:Hypertensive intracerebral hemorrhage (HICH) is a condition associated with significant morbidity, mortality, and disability, particularly among the elderly population. The management of moderate thalamic-basal ganglia cerebral hemorrhage primarily relies on conservative approaches. Nevertheless, the rate of long-term disability remains high. In recent years, there has been significant advancement in minimally invasive surgery and diffusion tensor imaging techniques. Consequently, the utilization of Diffusion Tensor Imaging (DTI) technology in patients with cerebral haemorrhage allows for the identification of the haematoma's location in relation to the Corticospinal Tract (CST). This enables the development of precise puncture pathways that can be visualized, thereby avoiding any potential damage to the CST. METHODS AND ANALYSIS:Diffusion Tensor Imaging (DTI) is a method used to assess the structural and physiological characteristics of biological tissue by examining the diffusion behavior of water molecules.In the central nervous system, limb paralysis will be inevitable if the corticospinal tract is damaged. By employing DTI imaging techniques on individuals, it becomes possible to visualize the spatial relationship between the hematoma and the CST. This approach allows avoidance of the CST during preoperative planning of the puncture path, thus reducing secondary injuries caused by the procedure. The primary objective of this study was to assess the ability of patients in the minimally invasive surgery group and the conservative group to perform activities of daily living after 6 months of treatment. In addition, secondary outcomes included assessment of hematoma resorption/clearance ratios, cytokine levels, complication rates, and therapeutic indexes at different treatment durations, as well as long-term safety and efficacy at 2-3 years of follow-up. Furthermore, subgroup analysis, and sensitivity analysis were conducted to further analyze the data. Logistic single-variate and multivariate regression analyses were applied to understand the adverse factors affecting prognosis. ETHICS AND DISSEMINATION:The clinical study was reviewed and approved by the Ethics Committee of the First People's Hospital of Yibin. The ethical number is: 2023 Review (64). REGISTRATION NUMBER:This protocol is registered in the Prospective Registry of Chinese Clinical Trial Registries (PROCCTR). The full date of first registration is 28/12/2023. The registration number for PROCCTR is ChiCTR2300079252.

Glioblastoma (GBM) is one of the most prevalent cancerous brain tumors. Former studies have reported that exosomes derived from M1-polarized macrophages (M1 exosomes) inhibit tumor occurrence and development through delivery of tumor suppressor genes. Also, microRNA-142-3p (miR-142-3p) has been verified to function as a tumor suppressor. GBM cell proliferation was evaluated by Cell Counting Kit-8 (CCK-8), colony formation assay and 5-ethynyl-2'-deoxyuridine (EdU) assay; cell apoptosis was determined by flow cytometry analysis and terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) assay. Mechanism investigations were conducted for analyzing the molecular mechanism by which miR-142-3p and M1 exosomes affect GBM progression. Upregulation of miR-142-3p expression was detected in M1-polarized macrophages and M1 exosomes. M1 exosomes inhibit GBM cell proliferation and trigger cell apoptosis. Functionally, miR-142-3p silencing promotes the proliferation and inhibits the apoptosis of GBM cells treated with M1 exosomes. As for molecular mechanism, miR-142-3p inhibits GBM cell growth via targeting high-mobility group box 1 (HMGB1). In addition, miR-142-3p/HMGB1 axis affects GBM cell immune escape through modulation of programmed death-1/programmed death ligand-1 (PD-1/PD-L1) checkpoint. Our study demonstrated that exosomal miR-142-3p from M1-polarized macrophages suppresses cell growth and immune escape in GBM through regulating HMGB1-mediated PD-1/PD-L1 checkpoint.

ObjectiveNeuroendoscopic surgery (NES) has been proven to be safe and effective in hematoma evacuation for cerebral hemorrhage. However, its efficacy for thalamic hemorrhage accompanied by intraventricular hematoma (THAVH) remains unclear. The aim of this study is to determine the efficacy of NES in treating THAVH.MethodA retrospective study was carried out. The data of patients diagnosed with THAVH were collected from January 1st, 2019, to January 1st, 2022. Patients received the NES or external ventricle drainage (EVD) treatment were assigned to the NES or EVD group, respectively. As primary outcomes, the hematoma evacuation volume, residual hematoma volume, and hematoma clearance rate were separately calculated based on the hematoma site; and the 180-day-mRS score was assessed. As secondary outcomes, the length of stay in the ICU and hospital, and the adverse events were also compared.ResultsThirty-five patients, aged 66.37 ± 6.62 years, were in the NES group; and 40 patients, aged 68.75 ± 7.22 years, were in the EVD group. The baseline characteristics in the two groups were similar (P > 0.05). The gross hematoma evacuation volume, volume of hematoma evacuated in the thalamus or the ventricle, and the hematoma clearance rate were greater in the NES group than in the EVD group on the 1st day after surgery (P < 0.05). The patients had a better rank of mRS in the NES group (P < 0.05). Compared with patients with mRS > 3, the mean residual hematoma volume in the thalamus of patients with mRS ≤3 on the 1st and 7th day were less in each group (P < 0.05), respectively. A residual hematoma volume in the ventricle of patients with mRS ≤3 was less than that of patients with mRS >3 in the EVD group on the 1st day after surgery (P < 0.05). GCS score on the 3rd day was greater in the NES group (P < 0.05). The incidence of lung infection was lower in the NES group (P < 0.05). The length of stay in the ICU and hospitalization duration were shorter in the NES group (P < 0.05).ConclusionsNeuroendoscopic surgery has a greater hematoma clearance rate, a lower lung infection rate and a shorter duration in the hospital. Neuroendoscopic surgery might improve patients’ prognosis. Neuroendoscopic surgery is a safe and effective procedure for treating thalamic hemorrhage accompanied by intraventricular hematoma.

Epilepsy is one of the most common symptoms in patients with gliomas; however, the mechanisms underlying its interaction are not yet clear. Moreover, epidemiological studies have not accurately identified patients with glioma-related epilepsy (GRE), and there is an urgent need to identify the molecular mechanisms and markers of its occurrence. We analyzed the demographics, transcriptome, whole-genome, and methylation sequences of 997 patients with glioma, to determine the genetic differences between glioma and GRE patients and to determine the upregulated molecular function, cellular composition, biological processes involved, signaling pathways, and immune cell infiltration. Twelve machine learning algorithms were refined into 113 combinatorial algorithms for building diagnostic recognition models. A total of 342 patients with GRE were identified with WHO grade 2 (174), grade 3 (107), and grade 4 (61). The mean age of the patients with GREs, with IDH mutations (n = 217 [63%]) and 1p19q non-codeletion (n = 169 [49%]), was 38 years old. GRE molecular functions were mainly passive transmembrane transporter protein activity, ion channel activity, and gated channel activity. Cellular components were enriched in the cation-channel and transmembrane transporter complexes. Cerebral cortical development regulates the membrane potential and synaptic organization as major biological processes. The signaling pathways mainly focused on cholinergic, GABAergic, and glutamatergic synapses. LASSO, combined with Random Forest, was the best diagnostic model and identified nine diagnostic genes. This study provides new insights and future perspectives for resolving the molecular mechanisms of GRE.

Capillary hemangiomas, usually found in skin and mucosal tissues, are rarely encountered within the spinal cord, presenting a significant diagnostic challenge. We report a rare case of intradural extramedullary capillary hemangioma at the conus medullaris in a 66-year-old female patient. Our initial diagnosis leaned towards a cystic hemangioblastoma based on MRI findings due to the presence of cystic formation with an enhanced mural nodule. However, surgical exploration and subsequent pathological examination revealed the lesion as a capillary hemangioma. To the authors’ knowledge, this case may represent the first documented instance of a spinal capillary hemangioma that mimics a cystic hemangioblastoma.

The choroid plexus (ChP) serves as the principal origin of cerebrospinal fluid (CSF). CSF hypersecretion due to ChP inflammation has emerged as an important pathogenesis of hydrocephalus recently. Nevertheless, the precise mechanisms of ChP inflammation and the ensuing CSF hypersecretion in hydrocephalus remain ill-defined. In the present study, we elucidate the critical role of macrophages in the pathogenesis of ChP inflammation. Specifically, we identify the chemokine CCL2, released by ChP epithelial cells, recruits CCR2+ monocytes to the ChP thereby inciting hydrocephalus pathogenesis. The accumulated ChP macrophages increase the inflammation in ChP epithelial cells through TNF-α/TNFR1/NF-κB signaling cascade, thereby leading to CSF hypersecretion. Strikingly, augmentation of ChP‒CCL2 using an adeno-associated viral approach (AAV) exacerbates macrophage recruitment, activation, and ventriculomegaly in rat PHH models. Systemic application of Bindarit, a specific CCL2 inhibitor, significantly inhibits ChP macrophage infiltration and activation and reduces CSF secretion rate. Furthermore, the administration of CCR2 antagonist (INCB 3284) reduces ChP macrophage accumulation and ventriculomegaly. This study not only unveils the ChP CCL2‒CCR2 signaling in the pathophysiology of hydrocephalus but also unveils Bindarit as a promising therapeutic choice for the management of posthemorrhagic hydrocephalus.

Hypertensive Intracerebral Hemorrhage (HICH) is one of the most common types of cerebral hemorrhage with a high mortality and disability rate. Currently, preoperative non-contrast computed tomography (NCCT) scanning-guided stereotactic hematoma removal has achieved good results in treating HICH, but some patients still have poor prognoses. This study collected relevant clinical and radiomic data by retrospectively collecting and analyzing 432 patients who underwent stereotactic hematoma removal for HICH from January 2017 to December 2020 at the Liuzhou Workers Hospital. The prognosis of patients after 90 days was judged by the modified Rankin Scale (mRS) scale and divided into the good prognosis group (mRS ≤ 3) and the poor prognosis group (mRS > 3). The 268 patients were randomly divided into training and test sets in the ratio of 8:2, with 214 patients in the training set and 54 patients in the test set. The least absolute shrinkage and selection operator (Lasso) was used to screen radiomics features. They were combining clinical features and radiomic features to build a joint prediction model of the nomogram. The AUCs of the clinical model for predicting different prognoses of patients undergoing stereotactic HICH were 0.957 and 0.922 in the training and test sets, respectively, while the AUCs of the radiomics model were 0.932 and 0.770, respectively, and the AUCs of the combined prediction model for building a nomogram were 0.987 and 0.932, respectively. Compared with a single clinical or radiological model, the nomogram constructed by fusing clinical variables and radiomic features could better identify the prognosis of HICH patients undergoing stereotactic hematoma removal after 90 days.

BACKGROUND:The prognosis of patients with thalamic hemorrhage is poor, and their long-term neurological impairment is heavy, which seriously affects their work and life.To comparatively analyse the efficacy and prognosis of patients with moderate hemorrhage in the thalamic region who underwent conservative treatment, stereotactic puncture surgery and neuroendoscopic surgery.METHOD:This study retrospectively analyzed hospitalization data from 139 adult patients with moderate-volume cerebral hemorrhage in the thalamo-endocapsular region. They were categorized into a stereotactic group (39cases), a neuroendoscopic group (36cases), and a conventional conservative group (64cases). Logistic regression analysis was used to assess risk factors for severe neurological deficits in patients. Multivariate regression modeling was used to compare the correlation of severe neurological deficits among the three groups of patients.RESULTS:Patients with thalamic moderate-volume cerebral hemorrhage had statistically significantly higher Assessment of Daily Living (ADL) scores in the stereotactic surgery group than in the conservative treatment group and the neuroendoscopic surgery group after 6 months of treatment (p< 0.001).The amount of residual hematoma was significantly lower in the surgery groups than in the conservative treatment group at 3 days, 7 days, and 2 weeks after the onset of the disease (P< 0.001).In multivariate logistic regression analyses, after adjusting for all covariates, the odds ratios for severe neurologic dysfunction in the stereotactic group and the neuroendoscopy group were, respectively, OR: 0.37 (0.12-0.87), P< 0.001 and 0.42 (0.23-1.13), P=0.361).CONCLUSION:In patients with moderate volume cerebral hemorrhage in the thalamus-inner capsule region cerebral hemorrhage, patients treated with stereotactic surgery combined with early hyperbaric oxygen therapy may have better long-term neurological recovery compared with conservative and neuroendoscopic surgical treatments.

Glioblastoma (GBM) displays an infiltrative growth characteristic that recruits neighboring normal cells to facilitate tumor growth, maintenance, and invasion into the brain. While the blood-brain barrier serves as a critical natural defense mechanism for the central nervous system, GBM disrupts this barrier, resulting in the infiltration of macrophages from the peripheral bone marrow and the activation of resident microglia. Recent advancements in single-cell transcriptomics and spatial transcriptomics have refined the categorization of cells within the tumor microenvironment for precise identification. The intricate interactions and influences on cell growth within the tumor microenvironment under multi-omics conditions are succinctly outlined. The factors and mechanisms involving microglia, macrophages, endothelial cells, and T cells that impact the growth of GBM are individually examined. The collaborative mechanisms of tumor cell-immune cell interactions within the tumor microenvironment synergistically promote the growth, infiltration, and metastasis of gliomas, while also influencing the immune status and therapeutic response of the tumor microenvironment. As immunotherapy continues to progress, targeting the cells within the inter-tumor microenvironment emerges as a promising novel therapeutic approach for GBM. By comprehensively understanding and intervening in the intricate cellular interactions within the tumor microenvironment, novel therapeutic modalities may be developed to enhance treatment outcomes for patients with GBM.

BACKGROUND:The efficacy of surgical intervention in ameliorating long-term prognosis for moderate volume of cerebral hemorrhage in the thalamus-internal capsule region remains unsubstantiated by clinical investigations. Consequently, the acquisition of credible evidence is imperative to authenticate the effectiveness of these methodologies. METHODS:One hundred and three eligible patients with moderate-volume thalamus-internal capsule region cerebral hemorrhage. Twenty-seven pairs of successful matches after using the 1:1 propensity score matching method, totaling 54 patients, were analyzed. The short- and long-term treatment outcomes of patients in the stereotactic surgery and conservative treatment groups were compared. The prognosis of the 2 groups of patients was analyzed by logistic regression analysis and model comparison. RESULTS:The primary outcome of this study was to assess the assessment of daily living scores after 6 months of treatment. Based on the analysis of this study, the assessment of daily living of the surgical group were significantly higher than those of the conservative treatment group after 6 months of treatment (P < 0.001), and the difference was statistically significant. The amount of residual hematoma was significantly lower in the stereotactic surgery group than in the conservative treatment group at 3 days, 7 days, and 2 weeks after the onset of the disease (P < 0.001), and the complication rate was lower than the conservative treatment group (P < 0.05). Univariate logistic regression showed that the risk of severe neurological dysfunction for patients in the surgery group was (odds ratio -0.27, 95% confidence interval: 0.08-0.86, P < 0.05). In multivariate logistic regression analysis, the odds ratio was 0.29 (95% confidence interval: 0.09-0.96, P < 0.05) after adjusting for all covariates. CONCLUSIONS:For moderate-volume thalamus-internal capsule region cerebral hemorrhage, stereotactic paracentesis has the advantage of a shorter hospital stay and a lower complication rate than conservative treatment. Moreover, it yields superior outcomes in terms of daily living assessment scores after six months of treatment and enhanced neurological recovery.
