Neurocritical care involves complex pathophysiological mechanisms, and its incidence is higher, injuries are more severe, and treatment is more challenging in high-altitude environments. This consensus, based on the latest domestic and international evidence-based medical data, establishes a standardized, goal-oriented framework for neurocritical care management applicable in high-altitude regions and nationwide. The consensus was developed following international standards for evidence quality assessment and underwent two rounds of Delphi expert consultation, resulting in 32 recommendation statements covering three parts: management systems, monitoring and assessment, and core strategies. Key updates include: advocating for the establishment of independent neurocritical care units and implementing precise tiered diagnosis and treatment based on the "Five Differences in Critical Care" concept; constructing a "trinity" multimodal brain monitoring system centered on cerebral blood flow, cerebral oxygenation, and brain function, emphasizing routine bedside transcranial Doppler ultrasound, cerebral oximetry, and continuous electroencephalography monitoring; shifting management strategies from mild hypothermia therapy to targeted temperature management, and defining the "446" target management pathway for the supercritical stage; emphasizing the assessment of static and dynamic cerebrovascular autoregulation functions through multimodal methods to achieve individualized optimal mean arterial pressure management; elevating cerebrospinal fluid management goals to the level of "glymphatic system" function maintenance; implementing a multidisciplinary collaborative, whole-process management model focusing on patients' long-term neurological functional outcomes; de-escalation criteria include multidimensional indicators such as recovery of brain structure, restoration of cerebrovascular autoregulation, improvement in cerebrospinal fluid dynamics, and reduction in biomarker levels; and integrating cutting-edge technologies like artificial intelligence into post-critical care management and rehabilitation planning. This consensus systematically integrates the entire process of neurocritical care management, reflecting the modern connotation of goal-oriented, dynamic, and multimodal integration in neurocritical care medicine. It aims to adapt to new trends such as deepening understanding of pathophysiological mechanisms, the integration of medicine and engineering, and the empowerment of artificial intelligence, thereby further advancing the discipline of critical care medicine.

Autoimmune hepatitis (AIH) is a chronic inflammatory liver disease mediated by T lymphocytes, and it can progress to liver cirrhosis or even liver failure without timely intervention. As a natural flavonoid compound, naringenin (NAR) shows a potential value in the prevention and treatment of AIH through multiple mechanisms such as remodeling immune homeostasis, targeted inhibition of inflammatory pathways, antioxidation, regulating hepatocyte metabolism and apoptosis, improving mitochondrial function, and regulating intestinal flora. However, the clinical translation and application of NAR is limited by issues such as low bioavailability and insufficient efficiency of liver-targeted delivery. This article systematically reviews the mechanism of action of NAR in the prevention and treatment of AIH, explores the potential signaling pathways involved in this process, and analyzes existing challenges in its translation and application and future research directions, so as to provide a reference for further research on NAR and its application in the prevention and treatment of AIH.

ObjectiveType I interferon (IFN-I) signaling is essential for antiviral innate immunity, yet its sustained or excessive activation contributes to the pathogenesis of several autoimmune diseases and interferonopathies, such as systemic lupus erythematosus and Aicardi-Goutières syndrome. Current strategies targeting this pathway, exemplified by JAK inhibitors, act mainly on downstream signal transduction and provide limited direct control over upstream IFN-I production, while also carrying the risk of broad immunosuppression. Phyllanthus emblica L. has long been used in traditional medicine for inflammatory disorders, but the bioactive constituent responsible for its regulation of IFN-I signaling and the underlying molecular mechanism have not been clearly defined. This study aimed to identify the active anti-inflammatory component of P. emblica and to characterize its mechanism of action on the IFN-I pathway in macrophages. MethodsActive components ofP. emblica and their candidate targets were screened by network pharmacology using the TCMSP and DrugBank databases (oral bioavailability≥30%, drug-likeness≥0.18) and intersected with inflammation-related genes retrieved from public databases. The predicted interaction between EGCG and IFN-I pathway proteins (TBK1, IRF3, STAT1) was evaluated by molecular docking, with BX795 and GSK8612 used as reference TBK1 inhibitors. Mechanistic experiments were performed in THP-1-derived macrophages and primary bone marrow-derived macrophages (BMDM). Upstream signaling was activated by transfection of the nucleic acid analogs poly(I∶C) and poly(dA∶dT) or by lipopolysaccharide (LPS) stimulation, whereas downstream signaling was activated by exogenous IFN-β. An siRNA-mediated TREX1 knockdown model was used to mimic endogenous nucleic acid-driven interferonopathy. Expression of IFN-β1 and interferon-stimulated genes (ISGs) was measured by RT-qPCR, protein phosphorylation by Western blot, and IFN-β secretion by ELISA. Cellular thermal shift assay (CETSA) and drug affinity responsive target stability (DARTS) were used to probe the interactionbetween EGCG and IRF3. ResultsNetwork pharmacology identified (-)-epigallocatechin-3-gallate (EGCG) as a candidate IFN-I-suppressive constituent of P. emblica, with predicted binding to TBK1, IRF3, and STAT1. Molecular docking yielded binding energies of -9.2, -7.2, and -8.2 kcal/mol for TBK1, IRF3, and STAT1, respectively, indicating an affinity for TBK1 comparable to that of the reference inhibitors BX795 (-5.7 kcal/mol) and GSK8612 (-6.4 kcal/mol). EGCG suppressed IFN-β1 and ISG mRNA expression under poly (I∶C), poly (dA∶dT), and LPS stimulation in both THP-1 macrophages and BMDM. At the protein level, EGCG reduced the phosphorylation of TBK1 and IRF3 without affecting the levels of the upstream sensors cGAS and RIG-I, and lowered IFN-β secretion in a concentration-dependent manner. CETSA and DARTS showed that EGCG did not enhance the thermal stability or protease resistance of IRF3, indicating that its effect on IRF3 is indirect. Following IFN-β stimulation, prolonged EGCG treatment reduced STAT1 phosphorylation in a time-dependent manner without an apparent change in IRF9, and partially attenuated ISG transcription; this effect was not monotonicly concentration-dependent, and CXCL10 showed the most consistent suppression. In TREX1-knockdown cells, the elevated mRNA levels of ISG15, ISG56, and CXCL10 were reduced by EGCG. ConclusionEGCG suppresses IFN-I responses by concurrently inhibiting TBK1-IRF3-dependent IFN‑β production and JAK-STAT1-mediated downstream transcription. These in vitro findings provide a mechanistic basis for the anti-inflammatory use of P. emblica in traditional medicine and identify EGCG as a candidate for further evaluation in interferon-driven autoimmune disease models.

Pancreatic ductal adenocarcinoma (PDAC) has an extremely poor prognosis, and resistance to gemcitabine is one of the key reasons for treatment failure, with an underlying mechanism closely associated with lipid metabolic reprogramming in tumor cells. This article aims to systematically elaborate on the multidimensional drug resistance network constructed by such reprogramming and the feasibility of targeted intervention. Lipid metabolic reprogramming comprehensively remodels the metabolic homeostasis of PDAC cells by enhancing lipid uptake, de novo synthesis, storage, and oxidative catabolism in a synergistic manner. This process alters membrane lipid composition to impede drug influx and promote efflux, thereby reducing intracellular drug concentration. Meanwhile, it activates pathways involving sterol regulatory element-binding protein and peroxisome proliferator-activated receptor δ, couples lipid synthesis with cell survival, stemness, and anti-apoptotic capacity, and synergizes with autophagy to provide survival support through “lipophagy”. In addition, it reshapes the tumor microenvironment through “lipid hijacking” and the secretion of immunosuppressive mediators. Based on the above mechanisms, targeting key lipid metabolic enzymes (such as fatty acid synthase, stearoyl-CoA desaturase, carnitine palmitoyltransferase 1) or their upstream regulators has shown certain potential in reversing such drug resistance in preclinical studies. Although clinical translation faces the challenges such as systemic toxicity, metabolic redundancy in tumors, and patient heterogeneity, the development of biomarkers, intelligent drug delivery systems, and combined therapies may provide new ideas for overcoming drug resistance.

ObjectiveAutism spectrum disorder (ASD) is a neurodevelopmental condition characterized by difficulties with communication and social interaction, restricted and repetitive behaviors. Previous studies have indicated that individuals with ASD exhibit early and lifelong attention deficits, which are closely related to the core symptoms of ASD. Basic visual attention processes may provide a critical foundation for their social communication and interaction abilities. Therefore, this study explores the behavior of children with ASD in capturing attention to changes in topological properties. MethodsOur study recruited twenty-seven ASD children diagnosed by professional clinicians according to DSM-5 and twenty-eight typically developing (TD) age-matched controls. In an attention capture task, we recorded the saccadic behaviors of children with ASD and TD in response to topological change (TC) and non-topological change (nTC) stimuli. Saccadic reaction time (SRT), visual search time (VS), and first fixation dwell time (FFDT) were used as indicators of attentional bias. Pearson correlation tests between the clinical assessment scales and attentional bias were conducted. ResultsThis study found that TD children had significantly faster SRT (P<0.05) and VS (P<0.05) for the TC stimuli compared to the nTC stimuli, while the children with ASD did not exhibit significant differences in either measure (P>0.05). Additionally, ASD children demonstrated significantly less attention towards the TC targets (measured by FFDT), in comparison to TD children (P<0.05). Furthermore, ASD children exhibited a significant negative linear correlation between their attentional bias (measured by VS) and their scores on the compulsive subscale (P<0.05). ConclusionThe results suggest that children with ASD have difficulty shifting their attention to objects with topological changes during change detection. This atypical attention may affect the child’s cognitive and behavioral development, thereby impacting their social communication and interaction. In sum, our findings indicate that difficulties in attentional capture by TC may be a key feature of ASD.

Objective:To explore the mechanism of Xuanfei Dahe Decoction in treating asthmatic mice through network pharmacology and animal experiments.Methods:The active components and their targets of Xuanfei Dahe Decoction were retrieved from TCMSP, and the asthma targets were obtained by searching the GeneCards, DisGeNet, OMIM, TTD and DrugBank databases. PPI network of intersection targets was constructed using string database and Cytoscape 3.9.0 software. Go function and KEGG pathway enrichment were analyzed by metascape database. The mice were divided into a blank group of 6 mice and a model group of 30 mice according to the random number table method. The asthma model was prepared in the model group. Totally 30 successfully modeled mice were divided into the model group, the dexamethasone group, and Xuanfei Dahe Decoction low-, medium- and high-dosage groups according to the random number table method, with 6 mice in each group. On the 5th day, gavage was initiated. Xuanfei Dahe Decoction low-, medium- and high-dosage groups were respectively gavaged with Xuanfei Dahe Decoction liquid at concentrations of 6.84, 13.68 and 27.36 g/kg. The dexamethasone group was gavaged with dexamethasone acetate tablets at concentrations of 2.73 mg/kg. The blank group and the model group were gavaged with the same volume of sterile normal saline once a day for 14 consecutive days. The pathological changes of lung tissue were observed by HE staining, the level of serum IL-17 was detected by ELISA, and the expression of IL-17 in lung tissue was detected by immunohistochemistry.Results:120 asthma targets and 13 key targets were obtained from Xuanfei Dahe Decoction. Pathway enrichment analysis suggested that IL-17 signaling pathway was one of the key pathways. Compared with the model group, the levels of IL-17 in the serum of the low-dose, medium-dose and high-dose Xuanfei Dahe Decoction groups and the expression of IL-17A in the lung tissue of the medium-dose Xuanfei Dahe Decoction group decreased ( P<0.05). Conclusion:Xuanfei Dahe Decoction may treat asthma by restrain airway inflammation mediated by Th17/IL-17.

Aging is characterized by a gradual deterioration of the physiological integrity of cells,tissues,and or-gans,resulting in a decrease in the body's physiological functions and an acceleration of the onset of age-related diseases,ultimately leading to death.The aging of the liver,which is a critical metabolic organ,is closely linked to various chronic liver diseases,such as hepatitis,liver fibrosis,and cirrhosis,and it ex-acerbates their prognosis and is a primary risk factor for their development at all stages.Therefore,a comprehensive understanding of the causes,mechanisms,and potential therapeutic targets associated with liver aging holds significant clinical importance for delaying or potentially reversing liver aging and for treating chronic liver diseases.Stem cells,which are potential anti-aging agents,present a promising and effective alternative for managing liver aging.In this review,we systematically assess the driving factors,characteristics,and underlying mechanisms of liver aging.We then discuss the current status of the use of stem cells to mitigate liver senescence and address related liver diseases.The review reveals that a stem cell-based approach represents a promising therapeutic strategy for combating liver aging and associated diseases.
