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 systematically compare mature experiences of comprehensive drug value assessment in typical countries/regions and to provide decision-making references for China to establish a scientific and standardized comprehensive drug value assessment system for medical-insured drugs. METHODS The literature analysis was used to systematically review drug value assessment frameworks in 11 representative countries/regions， namely the UK， Canada， Italy， Australia， Germany， France， South Korea， Japan， the United States， as well as Taiwan （China） and Hong Kong （China）. Comparisons were made across three dimensions： assessment entities， value dimension， and application of results. RESULTS &CONCLUSIONS In most countries/regions， independent technical assessment institutions have been established as part of the drug value evaluation system， with the involvement of multiple stakeholders （e.g.， the UK， Canada）. The mainstream drug value assessment frameworks have generally transcended the traditional core dimensions of safety， efficacy， and cost-effectiveness， exhibiting two major trends： the continuous expansion of assessment dimensions and stricter evidence requirements. Assessment outcomes are closely integrated with payment policies， ranging from providing technical advice for decision-making （e.g.， Italy， France） to directly determining reimbursement eligibility （e.g.， the UK， Germany）. The following recommendations are proposed for China： first， establish an evaluation mechanism featuring multi-stakeholder participation and separation of evaluation from decision-making. Second， develop a comprehensive evaluation framework integrating clinical， economic， patient， and societal value， emphasizing quantitative indicator exploration and real-world evidence application. Third， promote direct linkage between value-based tiering outcomes and medical insurance reimbursement decisions or access negotiations to balance patient benefits， fund sustainability， and industrial innovation.

ObjectiveTo analyze the epidemiological characteristics of 8 major respiratory pathogens in influenza-like illness (ILI) cases with acute respiratory infections at fever clinics in Huangpu District, Shanghai from 2015 to 2024, and to provide a scientific basis for the prevention and treatment of respiratory diseases. MethodsA retrospective study was conducted in Huangpu District. Individuals meeting the case definition of ILI from 2015 to 2024 was registered. Their nasopharyngeal swabs were collected for pathogen detection. A total of 8 respiratory viruses were tested, including Influenza A virus (Flu A), Influenza B virus (Flu B), adenovirus (ADV), enterovirus/human rhinovirus (EV/HRV), human parainfluenza virus (HPIV), human coronavirus (HCoV), respiratory syncytial virus (RSV), and human metapneumovirus (HMPV). ResultsFrom 2015 to 2019, a total of 344 ILI cases were tested, of which 192 out of 344 cases (55.81%) were tested positive for single respiratory pathogen. From 2023 to 2024, 1 557 ILI cases were tested, with 572 out of 1 557 cases (36.74%) being positive for single pathogen. From 2023 to 2024, the positive rate of single pathogen in ILI cases was significantly lower than that in 2015‒2019 (χ²=42.66, P<0.001). Specifically, the positive rate of Flu A (χ²=74.43, P<0.001) decreased, while that of HPIV (χ²=8.66, P=0.003) increased, both with statistically significant differences. According to the seasonal pattern, the epidemic intensity of Flu A decreased in summer, while that of HPIV increased in summer and autumn. Demographic results showed statistically significant differences in the positive rates of EV/HRV between genders (χ²=22.38, P<0.001), with males exhibiting a higher positive rate than females. No statistically significant differences were identified in the positive rates of single pathogen among different age groups (χ²=4.42, P=0.110). Nevertheless, statistically significant differences were noted when comparing the positive rates of EV/HRV, Flu A, Flu B and HPIV across different age groups (P<0.05). EV/HRV was more commonly detected in the 15‒<25 age group (10.93%), while Flu A and HPIV had the highest positive rates in the ≥60 age group (21.24% and 4.77%). Flu B had the highest positive rate in the 25‒<60 age group (11.26%). 52.63% of cases with co-infections occurred during winter, with the primary pathogens involved being EV/HRV (9 cases) and HCoV (6 cases). The most prevalent combination of co-infection was Flu A with EV/HRV. ConclusionThe prevalence of respiratory pathogens among ILI cases from 2023 to 2024 exhibited notable fluctuations compared to that from 2015 to 2019. Therefore, influenza surveillance should be strengthened, and attention should also be paid to the prevalence of respiratory pathogens such as HPIV. These findings have profound implications for future research, surveillance, vaccine planning, and public health policy making.

ObjectiveTo investigate the efficacy of selective internal radiation therapy （SIRT） in patients with unresectable hepatocellular carcinoma， and to provide a reference for the selection of clinical treatment regimens. MethodsA retrospective analysis was performed for the clinical data of 73 patients with unresectable hepatocellular carcinoma who received yttrium-90 microsphere SIRT in Eastern Hepatobiliary Surgery Hospital from May 1， 2023 to September 1， 2024. According to tumor characteristics， physical status， liver reserve function， laboratory tests， and SIRT treatment strategy， the patients were divided into radiation segmentectomy group with 9 patients， conversion therapy group with 47 patients， and palliative treatment group with 17 patients. Based on the results of postoperative follow-up， modified Response Evaluation Criteria in Solid Tumors were used to assess radiographic images. A one-way analysis of variance was used for comparison of normally distributed continuous data between three groups， and the chi-square test was used for comparison of categorical data between three groups； the Logistic regression model was used to perform the multivariate analysis. ResultsThere was a significant difference in postoperative outcome between the radiation segmentectomy group， the conversion therapy group， and the palliative treatment group （χ²=30.060， P<0.001）. The disease control rate was 100.0% （9/9） in the radiation segmentectomy group， 83.0% （39/47） in the conversion therapy group， and 29.4% （5/17） in the palliative treatment group， with a significant difference between the three groups （χ²=19.575， P<0.001）， and there was also a significant difference in objective response rate between the three groups （χ²=17.749， P<0.001）. The multivariate Logistic regression analysis showed that the number of tumors （odds ratio ［OR］=0.085， 95% confidence interval ［CI］： 0.008 — 0.906， P=0.041） and combined targeted immunotherapy （OR=18.808， 95%CI： 1.704 — 207.616， P=0.017） were independent influencing factors for achieving complete response. ConclusionThe number of tumors is an independent influencing factor for the efficacy of SIRT and is an important basis for selecting different treatment goals. SIRT combined with targeted immunotherapy may achieve better efficacy.

Objective: To define the mechanism by which swine TRIM25 restricts vesicular stomatitis virus replication. Methods: Porcine 3D4/21 cells with TRIM25 overexpression or knockdown were infected with vesicular stomatitis virus. Viral replication was quantified by immunoblotting, quantitative reverse transcription polymerase chain reaction, and 50% tissue culture infectious dose assays. Type I interferon signaling was assessed by transcript quantification, interferon-beta and interferon-stimulated response element reporter assays, and co-immunoprecipitation.Viral RNA binding was tested by RNA immunoprecipitation. Results: TRIM25 overexpression reduced viral RNA and infectious titers, whereas TRIM25 knockdown increased replication (p < 0.01). TRIM25 increased interferon-beta and interferon-stimulated gene expression and enhanced interferon-beta and interferonstimulated response element promoter activity (p < 0.01). Mechanistically, TRIM25 promoted Lys63-linked ubiquitination of RIG-I and increased phosphorylation of TANK-binding kinase 1 and interferon regulatory factor 3. TRIM25 also bound vesicular stomatitis virus genomic RNA, and binding required the C-terminal region. Conclusions and Relevance: Porcine TRIM25 restricts vesicular stomatitis virus replication by amplifying type I interferon signaling and directly binding viral RNA.

Background: Nasopharyngeal carcinoma (NPC) is characterized by high programmed death-ligand 1 (PD-L1) expression and abundant infiltration of non-malignant lymphocytes, which renders patients potentially suitable candidates for immune checkpoint blockade therapies. Palate, lung, and nasal epithelium clone (PLUNC) inhibit the growth of NPC cells and enhance cellular apoptosis and differentiation. Currently, the relationship between PLUNC (as a tumor-suppressor) and PD-L1 in NPC is unclear. Methods: We collected clinical samples of NPC to verify the relationship between PLUNC and PD-L1. PLUNC plasmid was transfected into NPC cells, and the variation of PD-L1 was verified by western blot and immunofluorescence. In NPC cells, we verified the relationship of PD-L1, activating transcription factor 3 (ATF3), and β-catenin by western blot and immunofluorescence. Later, we further verified that PLUNC regulates PD-L1 through β-catenin. Finally, the effect of PLUNC on β-catenin was verified by co-immunoprecipitation (Co-IP). Results: We found that PLUNC expression was lower in NPC tissues than in paracancer tissues. PD-L1 expression was opposite to that of PLUNC. Western blot and immunofluorescence showed that β-catenin could upregulate ATF3 and PD-L1, while PLUNC could downregulate ATF3/PD-L1 by inhibiting the expression of β-catenin. PLUNC inhibits the entry of β-catenin into the nucleus. Co-IP experiments demonstrated that PLUNC inhibited the interaction of DEAD-box helicase 17 (DDX17) and β-catenin. Conclusions PLUNC downregulates the expression of PD-L1 by inhibiting the interaction of DDX17/β-catenin in NPC.

Objective:To evaluate the efficacy of curative esophagectomy versus definitive chemoradiotherapy (dCRT) in patients with clinical T1bN0M0 thoracic esophageal cancer.Methods:The propensity score matching (PSM) and retrospective cohort study was conducted. The clinico-pathological data of 163 patients with clinical T1bN0M0 thoracic esophageal cancer who were admitted to Henan Provincial People′s Hospital from January 2014 to December 2020 were collected. There were 125 males and 38 females, aged (58.9±7.0)years. Of 163 patients, 124 cases undergoing curative transthoracic esophagectomy were allocated into the radical resection group, 39 cases undergoing dCRT were allocated into the dCRT group. Observation indicators:(1) PSM and compari-son of clinicopathological characteristics of patients between the two groups after matching; (2) complications in the radical resection group and treatment status in the dCRT group; (3) survival analysis; (4) analysis of factors influencing patients′ prognosis. Comparison of measurement data with normal distribution between groups was conducted using the Welch t test. Comparison of measurement data with skewed distribution between groups was conducted using the Mann-Whitney U test. Comparison of count data between groups was conducted using the chi-square test or Fisher exact probability. Comparison of ordinal data was conducted using the Mann-Whitney U test. The Cox proportional hazard model was used for univariate and multivariate analyses. The Kaplan-Meier method was used to calculate survival rate and plot survival curve, and Log-rank test was used for survival analysis. PSM was performed using the 2∶1 nearest neighbor matching method. The caliper value was set as 0.05. Results:(1) PSM and comparison of clinicopathological charac-teristics of patients between the two groups after matching. Of the 163 patients, 117 cases were successfully matched, with 78 cases in the radical resection group and 39 cases in the dCRT group. After PSM, the elimination of tumor differentiation degree confounding bias ensured comparability. (2) Complications in the radical resection group and treatment status in the dCRT group.Among the 78 patients in the curative esophagectomy group, 22 cases developed complications within 30 days after surgery. There was no death within 30 days after surgery. Among the 39 patients in the dCRT group, 25 cases received concurrent chemoradiotherapy alone, 8 cases received induction chemo-therapy followed by concurrent chemoradiotherapy, 3 cases received sequential chemoradiotherapy, and 3 cases received radiotherapy alone. Among the 33 patients who received concurrent chemo-radiotherapy, 29 cases were treated with the XP regimen, and 4 cases with the FP regimen. Efficacy evaluation showed that 37 patients achieved complete remission, and 2 patients had residual lesions. Twenty-two patients developed treatment-related adverse reactions. (3) Survival analysis. After PSM, the follow-up duration was 58(range, 13-125)months in the radical resection group and 56(range, 10-129)months in the dCRT group. The postoperative 5-year overall survival rates were 95.7% and 97.1% in the radical resection group and dCRT group, respectively, showing no significant difference between the two groups ( χ2=0.001, P>0.05). The postoperative 5-year disease-free progression survival rates were 88.2% and 94.2% in the radical resection group and dCRT group, respectively, showing no significant difference between the two groups ( χ2=0.652, P>0.05). (4) Analysis of factors influencing patients prognosis. Age and pathological TNM stage were indepen-dent influencing factors for overall survival time in patients with clinical T1bN0M0 thoracic esophageal cancer ( hazard ratio=1.312, 2.945, 95% confidence interval as 1.042-1.711, 2.204-5.517, P<0.05). Age and pathological TNM stage were independent influencing factors for disease-free survival time in patients with clinical T1bN0M0 thoracic esophageal cancer ( hazard ratio=1.215, 3.301, 95% confidence interval as 1.012-1.699, 2.012-6.321, P<0.05). Conclusions:There is no significant difference in overall survival and disease-free survival between patients with clinical T1bN0M0 thoracic esophageal cancer undergoing curative esophagectomy and dCRT. The treatment modality is not an independent prognostic factor.

Constipation,a common functional gastrointestinal disorder,not only severely impairs patients'quality of life but is also highly comorbid with psychiatric conditions such as anxiety and depression.Emerging evidence indicates that gut microbiota dysbiosis is a critical link connecting these two disease states.On one hand,dysbiosis exacerbates constipation by affecting host metabolism and intestinal function;on the other,it plays a central role in the pathophysiology of mood disorders.This complex interaction is primarily mediated through the"microbiota-gut-brain axis."Therefore,elucidating the intrinsic relationship among anxiety,depression,gut microbiota,and constipation has become a frontier of interdisciplinary research.

Background::Computer-aided detection (CAD) software has been introduced to automatically interpret digital chest X-rays. This study aimed to evaluate the performance of CAD software (JF CXR-1 v3.0, which was developed by a domestic Hi-tech enterprise) in tuberculosis (TB) case finding in China.Methods::In 2019, we conducted an internal evaluation of the performance of JF CXR-1 v3.0 by reading standard images annotated by a panel of experts. In 2020, using the reading results of chest X-rays by a panel of experts as the reference standard, we conducted an on-site prospective study to evaluate the performance of JF CXR-1 v3.0 and local radiologists in TB case finding in 13 township health centers in Zhongmu County, Henan Province.Results::Internal assessment results based on 277 standard images showed that JF CXR-1 v3.0 had a sensitivity of 85.94% (95% confidence interval [CI]: 77.42%, 94.45%) and a specificity of 74.65% (95% CI: 68.81%, 80.49%) to distinguish active TB from other imaging conditions. In the on-site evaluation phase, images from 3705 outpatients who underwent chest X-ray detection were read by JF CXR-1 v3.0 and local radiologists in parallel. The imaging diagnosis of local radiologists for active TB had a sensitivity of 32.89% (95% CI: 22.33%, 43.46%) and a specificity of 99.28% (95% CI: 99.01%, 99.56%), while JF CXR-1 v3.0 showed a significantly higher sensitivity of 92.11% (95% CI: 86.04%, 98.17%) ( p < 0.05) and maintained high specificity at 94.54% (95% CI: 93.81%, 95.28%). Conclusions::CAD software could play a positive role in improving the TB case finding capability of township health centers.

Objective To investigate the effect of miR-29b-3p targeting insulin-like growth factor-1(IGF-1)on high glucose-induced injury in human retinal microvascular endothelial cells(HRMECs)and the phosphatidylinositol 3-kinase(PI3K)/protein kinase B(Akt)/mammalian target of rapamycin(mTOR)signaling pathway.Methods HRMECs were di-vided into the following groups:control group(normal culture),high glucose(HG)group(treated with 30.0 mmol·L-1 glucose for 48 h),inhibitor-NC group,miR-29b-3p inhibitor group,miR-29b-3p inhibitor+si-NC group,miR-29b-3p inhib-itor+si-IGF-1 group(all transfected with corresponding plasmids for 24 h after HG treatment),and LY294002 group(treated with 40 μmol·L-1 LY294002 for 24 h).The expression level of miR-29b-3p was detected by quantitative real-time PCR(qRT-PCR).Cell viability was assessed using the Cell Counting Kit-8(CCK-8)assay.Intracellular reactive oxygen species(ROS)levels were measured by immunofluorescence.The expression levels of malondialdehyde(MDA),superox-ide dismutase(SOD),and glutathione peroxidase(GSH-Px)were determined using enzyme-linked immunosorbent assay(ELISA).Cell apoptosis was analyzed by flow cytometry.Autophagosome formation was observed under a transmission electron microscope.The protein expression levels related to apoptosis,autophagy,IGF-1,and the PI3K/Akt/mTOR path-way were examined by Western blot.The targeting relationship between miR-29b-3p and IGF-1 was verified by a dual-lucif-erase reporter assay.Results Compared with the Control group,the HG group showed significant increases in the ex-pression levels of miR-29b-3p,ROS,MDA,Bax,Cleaved-caspase 3,p62,the p-PI3K/PI3K ratio,the p-Akt/Akt ratio,the p-mTOR/mTOR ratio,and the cell apoptosis rate;whereas the expression levels of IGF-1,SOD,GSH-Px,the LC3Ⅱ/LC3Ⅰ ratio,cell viability,and the number of autophagosomes were significantly decreased(all P＜0.05).Compared with the in-hibitor-NC group,the miR-29b-3p inhibitor group exhibited significant decreases in the expression levels of miR-29b-3p,ROS,MDA,Bax,Cleaved-caspase 3,p62,the p-PI3K/PI3K ratio,the p-Akt/Akt ratio,the p-mTOR/mTOR ratio,and the cell apoptosis rate;while the expression levels of IGF-1,SOD,GSH-Px,the LC3Ⅱ/LC3Ⅰ ratio,cell viability,and the num-ber of autophagosomes were significantly increased(all P＜0.05).Compared with the miR-29b-3p inhibitor+si-NC group,the miR-29b-3p inhibitor+si-IGF-1 group demonstrated significant increases in the expression levels of miR-29b-3p,ROS,MDA,Bax,Cleaved-caspase 3,p62,the p-PI3K/PI3K ratio,the p-Akt/Akt ratio,the p-mTOR/mTOR ratio,and the cell apoptosis rate;whereas the expression levels of IGF-1,SOD,GSH-Px,the LC3Ⅱ/LC3Ⅰ ratio,cell viability,and the number of autophagosomes were significantly decreased(all P＜0.05).Compared with the HG group,the LY294002 group showed significant decreases in the expression levels of miR-29b-3p,ROS,MDA,Bax,Cleaved-caspase 3,p62,the p-PI3K/PI3K ratio,the p-Akt/Akt ratio,the p-mTOR/mTOR ratio,and the cell apoptosis rate;while the expression levels of IGF-1,SOD,GSH-Px,the LC3Ⅱ/LC3Ⅰ ratio,cell viability,and the number of autophagosomes were significantly increased(all P＜0.05).The dual-luciferase activity was significantly lower in cells co-transfected with IGF-1-WT and miR-29b-3p mimic compared to miR-NC cells(P＜0.05).Conclusion Inhibition of miR-29b-3p can target upregulation of IGF-1 expression levels,thereby inhibiting the PI3K/Akt/mTOR pathway and improving high glucose induced cell damage in HRMECs.
