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.

Objective:To investigate the correlations and regression models among adenoid-nasopharynx measurement indices (the linear ratio A/N, the two-dimensional area ratio 2D_A/N, and the three-dimensional volume ratio 3D_A/N), to evaluate the feasibility of predicting three-dimensional parameters from two-dimensional measurements.Methods:This cross-sectional study analysed 4 307 CBCT scans and lateral nasopharyngeal radiographs from 4-12-year-old children (July 2023-January 2025). Children with acute infection, major systemic disease, craniofacial anomalies, prior maxillofacial surgery, poor-quality images, or no consent were excluded. 3D_A/N was defined as adenoid volume/(adenoid+airway volume); 2D_A/N as adenoid area/total area; and linear A/N as adenoid thickness/nasopharyngeal thickness. Pearson correlation and multiple linear regression were used to quantify 2D-to-3D agreement, and independent-sample t-tests were employed to compare age, sex and seasonal subgroups. Results:(1) Significant sex-related differences in adenoid hypertrophy were detected at ages 5, 8, 9 and 11 years. In the 5-year-old group, females had significantly higher 3D_A/N and 2D_A/N values than males (3D_A/N: 0.76±0.10 vs. 0.74±0.10, t=-1.99, P=0.047; 2D_A/N: 0.66±0.10 vs. 0.64±0.09, t=-2.71, P=0.007). In the 8-year-old group, males exhibited significantly higher A/N and 3D_A/N values than females (A/N: 0.64±0.06 vs. 0.63±0.06, t=4.49, P<0.001; 3D_A/N: 0.66±0.12 vs. 0.64±0.12, t=2.00, P=0.046). In the 9-year-old group, males showed significantly higher 3D_A/N values than females (0.65±0.11 vs. 0.63±0.12, t=2.46, P=0.014). In the 11-year-old group, males had significantly higher A/N values than females (0.62±0.06 vs. 0.59±0.05, t=4.79, P<0.001). (2) The linear A/N ratio correlated moderately with 3D_A/N ( r=0.82), whereas, 2D_A/N showed an excellent correlation ( r=0.97); multiple regression confirmed 2D_A/N as the principal predictor of 3D_A/N. (3) Seasonal analysis revealed markedly greater adenoid hypertrophy in winter than in summer for children aged 4-9 years, while, no seasonal difference was found in the 10-12 year group; overall, winter hypertrophy was most pronounced in younger children. Conclusion:2D_A/N demonstrates a marked advantage in predicting 3D_A/N. When combined with A/N and age factors, it can effectively model changes in the 3D volume ratio of the adenoid, underscoring the clinical value of lateral cephalometric measurements for evaluating adenoid hypertrophy in children. Moreover, adenoid hypertrophy is influenced by age, sex and seasonal factors.

Objective To explore the relationship between the ferroptosis-related molecules heme oxygenase-1(HMOX1)and mitogen-activated protein kinase 14(MAPK14)with the onset and prognosis of acute lung injury(ALI)in children with sepsis.Methods A total of 102 children with sepsis were selected,including 54 in the ALI group and 48 in the non-ALI group.Clinical data,laboratory tests,organ function scores and serum levels of HMOX1 and MAPK14 were compared between the two groups.The mortality rates of children with different levels of HMOX1 and MAPK14 at 28-day and 90-day were analyzed.Results Compared with the non-ALI group,procalcitonin(PCT),lactate(Lac),pediatric organ dysfunction Logistic-2 score(PELOD-2),pediatric risk of mortality score version 3(PRISM III)and sequential organ failure assessment(SOFA)scores were increased in the ALI group(P＜0.05).Serum levels of HMOX1 and MAPK14 were significantly higher in the ALI group than those in the non-ALI group(P＜0.05).HMOX1 and MAPK14 showed good predictive value for the occurrence of ALI in sepsis patients,with AUC values of 0.872(95%CI:0.791-0.930)and 0.825(95%CI:0.737-0.893),and the optimal cutoff values were 3.1 μg/L and 3.8 μg/L,respectively.After grouping by the cutoff values of HMOX1 and MAPK14,there were no significant differences in the 28-day and 90-day mortality rates in children with different levels of HMOX1 and MAPK14(P＞0.05).Conclusion The expression levels of serum HMOX1 and MAPK14 increase in the early stage of sepsis-related ALI,which may serve as biomarkers for the onset of ALI,and they have no significant impact on the prognosis of children.

Traditional Chinese medicine(TCM)exerts integrative effects on complex diseases owing to the char-acteristics of multiple components with multiple targets.However,the syndrome-based system of diagnosis and treatment in TCM can easily lead to bias because of varying medication preferences among physicians,which has been a major challenge in the global acceptance and application of TCM.Therefore,a standardized TCM prescription system needs to be explored to promote its clinical application.In this study,we first developed a gradient weighted disease-target-herbal ingredient-herb network to aid TCM formulation.We tested its efficacy against intracerebral hemorrhage(ICH).First,the top 100 ICH targets in the GeneCards database were screened according to their relevance scores.Then,SymMap and Traditional Chinese Medicine Systems Pharmacology(TCMSP)databases were applied to find out the target-related ingredients and ingredient-containing herbs,respectively.The relevance of the resulting ingredients and herbs to ICH was determined by adding the relevance scores of the corresponding targets.The top five ICH therapeutic herbs were combined to form a tailored TCM prescriptions.The absorbed components in the serum were detected.In a mouse model of ICH,the new prescription exerted multifaceted effects,including improved neurological function,as well as attenuated neuronal damage,cell apoptosis,vascular leakage,and neuroinflammation.These effects matched well with the core pathological changes in ICH.The multi-targets-directed gradient-weighting strategy presents a promising avenue for tailoring precise,multipronged,unbiased,and standardized TCM prescriptions for complex diseases.This study provides a paradigm for advanced achievements-driven modern innovation in TCM concepts.

Objective To Investigate the efficacy of modified electroconvulsive therapy(MECT)in patients with schizophrenia across different genders.Methods From May 2018 to August 2022,481 patients with schizophrenia were recruited from three psychiatric hospitals in Luzhou,Zigong,and Yibin.According to gender grouping,both groups received adjunctive MECT treatment for two consecutive weeks for a total of six treatments.The differences in positive and negative syndrome scale(PANSS)scores before and after treatment,UKU adverse reaction rating scale(UKU),and gastrointestinal symptom rating scale(GSRS)scores were compared between the two groups.Results After quality control,463 cases were followed up for analysis including 246 males and 217 females.Compared with pre-treatment,the total PANSS score and scores on each subscale were significantly reduced in both genders after treatment(P<0.001).When comparing the reduction rates between the groups,the male patients showed a higher reduction rate in negative symptoms than the female patients(31.24%±30.24%vs.25.80%±33.96%,P<0.05).However,there were no significant differences between the two groups in the reduction rates of the total score,positive symptoms,and general psychopathology(P>0.05).The comparison of adverse reactions showed that the frequency of other types of adverse reactions was higher in female patients than in male patients(47.47%vs.37.80%,P<0.05).However,no significant differences were observed in the adverse reactions related to the mental,neurological,autonomic nervous system,and gastrointestinal systems(P>0.05).Correlation analysis revealed that the reduction rate of the PANSS total score was positively correlated with smoking history(r=0.135,P=0.034)and alcohol history(r=0.160,P=0.012)in male patients,while the reduction rate of the PANSS total score was negatively correlated with the disease duration(r=-0.210,P=0.002)and positively correlated with the age of onset(r=0.145,P=0.032)in female patients.Conclusion MECT is significantly effective for both male and female patients with schizophrenia.Compared to female patients,MECT shows a more pronounced effect on negative symptoms in male patients.Additionally,the factors related to the efficacy of MECT differ between genders,indicating that it is necessary to consider the clinical characteristics of patients comprehensively when selecting an MECT treatment plan.

Objective To explore the changes of durability properties of reusable surgical gowns when used in dry and wet conditions.Methods Reusable surgical gowns made of single-layer polyester fiber or 3-layer composite material were selected as test samples,and a Martindale abrasion and pilling tester was used as the basic test platform and modified to form fixtures suitable for the wet state environment.The reusable surgical gowns underwent abrasion experiments in wet and dry conditions to observe the changes in their fiber structure,and were subjected to water penetration resistance and swelling strength tests.Results Visually the reusable surgical gowns had few changes of the microscopic textile fiber structure in dry and wet conditions,and the gowns made of single-layer polyster fiber gained advantages over the outer layers of those of 3-layer composite material in abrasion resistance with the same friction cycles.In dry and wet conditions,the hydrostatic pressure values of the gowns of single-layer polyster fiber gradually decreased with the increase of the degree of abrasion,which were always lower than those of the gowns of 3-layer composite material;the swelling strength of the gowns of single-layer polyster fiber was always greater than that of the gowns of 3-layer composite material,which decreased with the deterioration of the wear more significantly than that of the gowns of 3-layer composite material.Conclusion The reusable surgical gowns made of single-layer polyester fiber or 3-layer composite material have few differences in durability and protective properties at the early stages of ablation in dry and wet conditions.The durability of the gowns decreases as the degree of wear increases,while the trend of the decrease is slowing down until the fabric breaks down and completely loses its barrier effect.[Chinese Medical Equipment Journal,2025,46(6):28-33]

Objective:To investigate the changes and effects of the Wnt/β-catenin pathway during hypoxia-reoxygenation in human renal tubular epithelial(HK-2)cells.Methods:HK-2 cells were randomly divided into control group(Control),model group(Model),model+interference empty vector group(Model+NC),and model+interference group(Model+Si-β-catenin).Cells in the control group were cultured routinely.Cells in the Model group were intervened with hypoxia for 6 hours and reoxygenation for 2 hours to construct a hypoxia-reoxygenation model.HK-2 cells in the Model+NC group and the Model+Si-β-catenin group were transfected with β-catenin interference empty vector and β-catenin interference vector respectively,and then a hypoxia-reoxygenation model was constructed.After corresponding interventions,cells were collected.The apoptosis of cells in each group was detected by flow cytometry.The expression of matrix metalloproteinase-7(MMP-7)and α-smooth muscle actin(α-SMA)was detected by immunofluorescence.The expression level of Wnt pathway-related proteins was detected by Western blotting.Results:Compared with that in the control group,the apoptosis rate of cells in the Model group was significantly up-regulated,and there was no significant difference in cell apoptosis between the Model group,the Model+NC group and the Model+Si-β-catenin group.The results of WB detection showed that there was no significant difference in the expression of GSK-3β protein in the cells among the control group,the model group,the model+NC group and the model+Si-β-catenin group.Compared with that in the control group,the expression of p-GSK-3β protein in the Model group was significantly up-regulated,while there was no significant difference in the expression of p-GSK-3βprotein between the Model group,the Model+NC group and the Model+Si-β-catenin group.The results of immunofluorescence detection showed that MMP-7 and α-SMA in the Model group were significantly increased compared with that in the control group,while there was no significant difference between the Model group and the Model+NC group.Compared with the Model+NC group,MMP-7 and α-SMA in the Model+Si-β-catenin group were significantly down-regulated.Conclusion:The Wnt/β-catenin pathway is activated in HK-2 cells during hypoxia-reoxygenation and promotes the expression of fibrosis-related proteins.Inhibiting β-catenin can improve its fibrosis induction level.

Objective To explore the relationship between the ferroptosis-related molecules heme oxygenase-1(HMOX1)and mitogen-activated protein kinase 14(MAPK14)with the onset and prognosis of acute lung injury(ALI)in children with sepsis.Methods A total of 102 children with sepsis were selected,including 54 in the ALI group and 48 in the non-ALI group.Clinical data,laboratory tests,organ function scores and serum levels of HMOX1 and MAPK14 were compared between the two groups.The mortality rates of children with different levels of HMOX1 and MAPK14 at 28-day and 90-day were analyzed.Results Compared with the non-ALI group,procalcitonin(PCT),lactate(Lac),pediatric organ dysfunction Logistic-2 score(PELOD-2),pediatric risk of mortality score version 3(PRISM III)and sequential organ failure assessment(SOFA)scores were increased in the ALI group(P＜0.05).Serum levels of HMOX1 and MAPK14 were significantly higher in the ALI group than those in the non-ALI group(P＜0.05).HMOX1 and MAPK14 showed good predictive value for the occurrence of ALI in sepsis patients,with AUC values of 0.872(95%CI:0.791-0.930)and 0.825(95%CI:0.737-0.893),and the optimal cutoff values were 3.1 μg/L and 3.8 μg/L,respectively.After grouping by the cutoff values of HMOX1 and MAPK14,there were no significant differences in the 28-day and 90-day mortality rates in children with different levels of HMOX1 and MAPK14(P＞0.05).Conclusion The expression levels of serum HMOX1 and MAPK14 increase in the early stage of sepsis-related ALI,which may serve as biomarkers for the onset of ALI,and they have no significant impact on the prognosis of children.

Objective To explore the symptom prevalence in the patients with pulmonary nodules in Lingnan area and to investigate the influencing factors,thus to provide data support for the construction of differentiation and treatment system of symptoms-syndrome elements-syndromes-constitutions for patients with pulmonary nodules,and to promote the establishment of secondary prevention system of lung cancer with the in-depth participation of traditional Chinese medicine(TCM).Methods A cross-sectional study was adopted to investigate patients with pulmonary nodules who admitted in the First Affiliated Hospital of Guangzhou University of Chinese Medicine from August 2023 to January 2024.Data collection covered the basic information,clinical characteristics and symptoms of the patients.Likert four-level scale was used for the grading of the severity of the symptoms,multivariate linear regression was adopted to construct three regression models,and then the factors influencing the severity of symptoms of patients with pulmonary nodules were explored.Results(1)A total of 274 patients were enrolled in the analysis,including 160 females and 114 males,with a mean age of(54.44±12.00)years old and the symptom scores averaging(3.97±3.80)point.The included patients with pulmonary nodules were characterized by females outnumbering males,a higher proportion of middle-aged and elderly people,multiple pulmonary nodules being more common.(2)The analysis of the symptoms of the 274 patients showed that symptoms with an incidence over 30%were fatigue(116 cases,42.34%),cough(105 cases,38.32%),expectoration of white sputum(89 cases,32.48%),and irritability and distress(87 cases,31.75%).(3)Multivariate linear regression analysis after variable adjustment suggested that the overall symptomatic severity in the male was milder than that in the female[β=-1.67,95%CI(-2.67,-0.68),P<0.001],and symptom score was positively correlated with age[β=0.07,95%CI(0.03,0.10),P<0.001],history of exposure to secondhand smoke[β=1.27,95%CI(0.26,2.27),P=0.015],history of exposure to other hazardous substances[β=1.96,95%CI(0.39,3.53),P=0.015],and history of allergy[β=2.38,95%CI(1.22,3.54),P<0.001]significantly.Conclusion The overall symptoms of patients with pulmonary nodules in Lingnan area are mild,and the high prevalence of symptoms are fatigue,cough,expectoration of white sputum,and irritability and distress.The symptom severity is correlated with gender,age,history of exposure to secondhand smoke,history of exposure to other hazardous substances,and history of allergy.
