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 influence of sinus morphology on the safety of hydraulic sinus floor elevation surgery and provide a biomechanical basis for clinical treatment. Methods: After approval by the Medical Ethics Committee of the institution, cone beam computed tomography imaging data from nine patients were collected. The sinus morphologies were classified into slope, flat and concave types. Three-dimensional finite element models of maxillary sinuses with the aforementioned morphologies were constructed using Mimics, Geomagic, Solidworks, and ANSYS software, followed by a simulation of the hydraulic elevation process. The sinus membrane elevation height was set at 1-6 mm. The pressure required for elevation and the equivalent, compressive, tensile, and shear stresses generated on the sinus membrane were recorded and analyzed. The equivalent stress distribution on the sinus membrane was visualized using contour plots. Results: The elevation pressure and the equivalent, compressive, tensile, and shear stresses generated on the sinus membrane increased along with the elevation height. When the sinus membrane was lifted to 6 mm, the elevation pressure was (301.17 ± 98.1) kPa, (151.85 ± 3.7) kPa, and (149.36 ± 10.31) kPa in the slope, flat and concave finite element analysis models, respectively. The equivalent stress was (1 023.86 ± 201.99) kPa in the slope sinuses, comparing with (687.91 ± 69.08) kPa and (698.27 ± 96.09) kPa in the flat and concave sinuses. Higher elevation pressure and the equivalent stress, compressive stress and shear stress values were found in the slope sinus than in the flat and concave sinuses under the same elevation height (P < 0.05). Stress distribution analysis revealed that stress was uniformly distributed in the flat sinuses, followed by concave sinuses, but asymmetrically distributed in the slope sinuses Conclusions The slope sinuses demonstrated inferior safety and efficiency compared with the flat and concave sinuses when performing hydraulic sinus floor elevation surgery.

Objective The present study aimed to evaluate the clinical efficacy of hydraulic sinus floor elevation for the treatment of insufficient bone height in the posterior maxilla through a systematic review and Meta-analysis, so as to provide evidence for clinical practice. Methods Databases including PubMed, Embase, Cochrane Library, and Clinical Trials.gov were searched up to May 2025. Randomized controlled trials, non-randomized controlled trials, cohort studies, cross-sectional studies, and case-control studies that involved patients receiving hydraulic sinus floor elevation with simultaneous or delayed implant placement were included. Exclusion criteria comprised in vitro studies, animal experiments, narrative reviews, unpublished data, commentaries or expert opinions, studies with unclear sample sizes, and publications without full-text access or unavailable outcome data. Three investigators independently performed literature screening and quality assessment. A single-arm Meta-analysis was conducted using Stata 18.0 for studies meeting the inclusion criteria. The outcome measures were the incidence of sinus membrane perforation, implant survival rate, and endo-sinus bone gain. The Cochrane Risk of Bias 2 (RoB2) tool and the Joanna Briggs Institute (JBI) critical appraisal checklist were used to assess the methodological quality of randomized controlled trials and non-randomized controlled trials, respectively. The overall certainty of evidence was assessed using the GRADE（Grading of Recommendations Assessment, Development and Evaluation）system. Results Nineteen studies with 982 patients, 1 151 elevated sites, and 1 263 implants were finally included. The Meta-analysis showed that the intraoperative sinus membrane perforation rate of hydraulic sinus floor elevation was 2.0% [ES = 0.02, 95% CI (0.00, 0.04)] (18 studies, 1 061 sites); the implant survival rate was 99.0% [ES = 0.99, 95% CI (0.97, 1.00)] (17 studies, 1 253 implants); and the mean vertical bone gain was 7.80 mm. For this outcome, heterogeneity among studies was extremely high (I2 = 98.6%), thus only descriptive analysis was performed. Egger's test revealed no significant publication bias for the three outcomes. GRADE grading indicated very low certainty of evidence for mucosal perforation, implant survival rate, and endo sinus bone gain. Conclusion Current preliminary evidence suggests that hydraulic sinus lift may be a safe minimally invasive technique, but the evidence is very low, and more high quality, long term follow up randomized controlled clinical trials are still needed for further verification.

Abstract On September 26, 2024, a municipal hospital in Jiaxing City reported a maternal case of Listeria monocytogenes infection. In order to clarify the source of infection, the Jiaxing Center for Disease Control and Prevention immediately conducted the epidemiological investigation, laboratory testing and related disposal work. The case presented with fever (37.9 ℃), gradually intensifying paroxysmal abdominal pain without obvious cause, and went to hospital on the day of onset. Due to fetal intrauterine distress, a male infant was delivered by cesarean section on the same day. The epidemiological investigation identified that the case usually consumed fruits, often store fruits such as watermelon and grapes in the refrigerator alongside raw meat, and the refrigerator had never been cleaned or disinfected, posing a risk of cross contamination. Laboratory tests on amniotic fluid sample from the pregnant woman, infant blood sample showed positive results for Listeria monocytogenes infection. One strain of Listeria monocytogenes was detected in a smear sample from the inner wall of the refrigerator, and all the strains were ST2 type. Consuming fruits contaminated with Listeria monocytogenes may be the main source of infection. Food safety education for pregnant women and their family members should be strengthened to reduce the risk of infection.

Objective: To establish a prediction model for high-risk cardiovascular disease (CVD) among residents aged 35 to 75 years, so as to provide the basis for improving CVD prevention and control measures. Methods: Permanent residents aged 35 to 75 years were selected from Dongcheng District, Beijing Municipality using the stratified random sampling method from 2018 to 2023. Demographic information, lifestyle, waist circumference and blood biochemical indicators were collected through questionnaire surveys, physical examinations and laboratory tests. Influencing factors for high-risk CVD among residents aged 35 to 75 years were identified using a multivariable logistic regression model, and a prediction model for high-risk CVD was established. The predictive effect was evaluated using the receiver operating characteristic (ROC) curve. Results: A total of 6 968 individuals were surveyed, including 2 821 males (40.49%) and 4 147 females (59.51%), and had a mean age of (59.92±9.33) years. There were 1 155 high-risk CVD population, with a detection rate of 16.58%. Multivariable logistic regression analysis showed that gender, age, smoking, central obesity, systolic blood pressure, fasting blood glucose, triglyceride and low-density lipoprotein cholesterol were influencing factors for high-risk CVD among residents aged 35 to 75 years (all P<0.05). The area under the ROC curve of the established prediction model was 0.849 (95%CI: 0.834-0.863), with a sensitivity of 0.693 and a specificity of 0.863, indicating good discrimination. Conclusion The model constructed by eight factors including demographic characteristics, lifestyle and blood biochemical indicators has good predictive value for high-risk CVD among residents aged 35 to 75 years.

Due to factors such as narrow airways and incomplete development of alveoli,newborns are prone to acute lung injury(ALI),which may progress to severe condition known as acute respiratory distress syndrome(ARDS).The mechanisms underlying the occurrence and progression of ALI in newborns involve various as-pects,including oxidative stress,iron death,inflammatory response and reduction of pulmonary surfactant.Further research into these mechanisms is expected to provide strategy to guide clinical management in novo pathway.

Objective To analyze the predictive value of Doppler ultrasound parameters com-bined with serum mitofusin-2 and caveolin-1(Cav-1)levels in pregnant women with preeclampsia for fetal growth restriction.Methods A total of 167 pregnant women with preeclampsia were selected as the study subjects and divided into fetal growth restriction group(n=63)and non-fetal growth re-striction group(n=104).Enzyme-linked immunosorbent assay(ELISA)was used to measure the serum levels of mitofusin-2 and Cav-1 in both groups.Multivariate logistic regression analysis was em-ployed to screen for influencing factors of fetal growth restriction.The receiver operating characteristic(ROC)curve was utilized to evaluate the predictive value of Doppler ultrasound parameters combined with serum mitofusin-2 and Cav-1 levels for fetal growth restriction.Results The gestational age at delivery in the fetal growth restriction group was significantly shorter than that in the non-fetal growth restriction group(P＜0.05).The serum levels of mitofusin-2 and Cav-1 in the fetal growth restriction group were significantly lower than those in the non-fetal growth restriction group(P＜0.05).The Doppler ultrasound parameters[umbilical artery peak systolic velocity/umbilical artery end-diastolic velocity(S/D),resistance index(RI)and pulsatility index(PI)]in the fetal growth restriction group were significantly higher than those in the non-fetal growth restriction group(P＜0.05).Multivariate logistic regression analysis revealed that gestational age at delivery,as well as the levels of mitofusin-2 and Cav-1 were influencing factors for fetal growth restriction(P＜0.05).The area under the curve(AUC)for the combined prediction of fetal growth restriction using S/D,RI,PI,mitofusin-2 and Cav-1 was superior to that of each individual indicator.Conclusion The AUC for predicting fetal growth restriction using Doppler ultrasound parameters combined with serum mitofusin-2 and Cav-1 levels in pregnant women with preeclampsia is 0.960,providing a clinically operable tool for early risk stratification of fetal growth restriction.

Objective To investigate the mechanism of the miR-518a-5p/histone deacetylase 6(HDAC6)axis in DNA oxidative damage in ovarian cancer(OC)SKOV3 cells.Methods Expression levels of miR-518a-5p and HDAC6 mRNA in OC tissues and in various cancer cells(A2780,SKOV3,CAOV3)were detected by qRT-PCR.SKOV3 cells were separated into Control,miR-NC,miR-518a-5p mimics,miR-518a-5p mimics+pcDNA-NC,and miR-518a-5p mimics+pc-HDAC6 groups.Cell proliferation and apoptosis were analyzed by colony-forming assay and Hoechst 33258 staining.Expression of phosphorylated histone H2AX(γ-H2AX)was detected by immunofluorescence assay and reactive oxygen species(ROS)were detected by flow cytometry.HDAC6,Bcl-2-associated X protein(Bax),and B-cell lymphoma-2(Bcl-2)protein expression were analyzed by Western blot.The regulatory relationship between miR-518a-5p and HDAC6 was analyzed by dual luciferase assay.The effect and mechanism of miR-518a-5p on oxidative DNA damage in OC cells were studied in a xenotransplantation tumor model.Results miR-518a-5p expression was decreased and HDAC6 expression was increased in OC tissues and A2780,SKOV3,and CAOV3 cells(P＜0.001).Expression levels of miR-518a-5p were lowest and expression levels of HDAC6 were highest in SKOV3 cells,and SKOV3 cells were therefore selected for subsequent experiments.miR-518a-5p expression,apoptosis rate,number of γ-H2AX-positive cells,relative ROS fluorescence intensity,and expression of Bax were all higher in the miR-518a-5p mimics group compared with the miR-NC group,while HDAC6 mRNA and protein expression,Bcl-2 expression,and colony-formation number were all lower(P＜0.001).HDAC6 mRNA and protein expression,colony-formation number,and expression of Bcl-2 were higher in the miR-518a-5p mimics+pc-HDAC6 group compared with the miR-518a-5p mimics+pcDNA-NC group,and the apoptosis rate,number of γ-H2AX-positive cells,relative ROS fluorescence intensity,and expression of Bax were all lower(P＜0.001).HDAC6 had a targeted regulatory relationship with miR-518a-5p.Overexpression of miR-518a-5p decreased tumor volume,weight,and HDAC6 protein expression in tumor tissues,and increased γ-H2AX expression in vivo(P＜0.001).Upregulation of HDAC6 expression by overexpression of miR-518a-5p increased graft tumor volume,weight,and HDAC6 protein expression and decreased γ-H2AX-positive expression(P＜0.05).Conclusions miR-518a-5p expression is reduced and HDAC6 expression is increased in OC tissues and cells.Overexpression of miR-518a-5p can induce oxidative DNA damage in SKOV3 cells by inhibiting HDAC6 expression,thereby inhibiting cell proliferation and promoting cell apoptosis.

This article is based on modern psychology and TCM emotional theory,combined with facial expression recognition technology,to apply deep learning methods to the digital research of TCM emotions to more accurately capture and analyze patients'emotional states.A cross-disciplinary framework was established by synthesizing facial expression-emotion correlations from psychological and TCM perspectives.The methodology included:Data annotation of TCM-defined emotional expressions using standardized coding systems;Facial expression acquisition,spatiotemporal feature extraction and emotion classification through a 3D convolutional neural network(3D CNN).The framework achieved 91.43%accuracy in video-based emotion classification.High-arousal emotional states demonstrated superior recognition performance,with anger showing optimal recall(1.000 0)and F1-score(0.946 3),while surprise attained the highest precision(0.976 0).These findings aligned with TCM pathological characteristic of"anger induces qi ascending,surprise disrupts qi flow".The digital recognition framework for TCM emotional quantification based on facial expression recognition technology exhibits strong alignment with TCM observation diagnosis,providing clinicians with an objective tool to assess the"seven emotions"and elucidating emotion-facial correlations in classical TCM theory.Future research should focus on longitudinal validation across diverse populations and establish development pathways for AI-assisted TCM diagnostic systems.
