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 investigate the effects of metformin on the immune functions of immature dendritic cells （imDCs） and the underlying mechanisms. MethodsMouse bone marrow-derived imDCs were treated with different concentrations of metformin. The working concentration and treatment time of metformin in this study were determined based on the results of cell apoptosis and cell viability assays. The effects of metformin on the phagocytic capacity of imDCs was evaluated using an antigen endocytosis assay. The expression of cluster of differentiation 205 （CD205）， the polymerization of filamentous actin （F-actin）， and the underlying regulatory mechanisms were investigated through flow cytometry， laser confocal fluorescence microscopy， and Western blot. ResultsThe working concentrations of metformin were 1， 2， 4 mmol/L for 24 h determined by the apoptosis and cell viability assays.Metformin significantly suppressed the phagocytic capacity of imDCs， down-regulated the expression of the mannose receptor CD205 on the cell surface， which was closely associated with phagocytic function； metformin inhibited the RhoA-ROCK1-LIMK1-Cofilin signaling pathway， which inhibited the polymerization of F-actin and disturbed its dynamic remodeling of imDCs. ConclusionMetformin can inhibit the expression of CD205 and disrupt the remodeling of F-actin， thereby suppressing the antigen-capturing capacity of imDCs.

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.

ObjectiveTo compare the application value of two endoscopic ultrasound （EUS）-guided targeted vascular embolization techniques in secondary prevention of esophagogastric variceal bleeding （EGVB）， and to clarify the clinical advantages of targeted main trunk embolization. MethodsA retrospective analysis was performed for 59 patients who were admitted to Beijing Ditan Hospital， Capital Medical University， from April 2023 to July 2024 and received secondary prevention of gastroesophageal varices （GOV）-type EGVB， and according to the surgical procedure， they were divided into EUS-PCSS targeting the distal segment of the source vessel or perforating branch vessels （EUS-PCSS-D/P） group with 29 patients and EUS-PCSS targeting the source vascular trunk （EUS-PCSS-T） group with 30 patients. The two groups were observed in terms of rebleeding rate， variceal eradication efficiency， and the incidence rate of adverse events. The t-test or the Mann-Whitney U test was used for comparison of continuous data between two groups， and the chi-square test or the Fisher’s exact test was used for comparison of categorical data between two groups； the Mann-Whitney U test was used for subgroup analysis， and ordinal Logistic regression was used for multivariate analysis. ResultsThere were no significant differences in baseline data between the two groups （all P>0.05）. Compared with the EUS-PCSS-D/P group， the EUS-PCSS-T group had a significantly smaller diameter of punctured vessels （5.39±2.03 mm vs 7.00±2.21 mm， t=3.012， P=0.005）， a significantly lower treatment rate of supplementary endoscopic injection sclerotherapy （EIS） （40.00% vs 79.31%， χ²=7.521， P=0.006）， and a significantly lower amount of lauromacrogol used （16.08±7.25 mL vs 22.17±6.83 mL， t=2.518， P=0.015）， and there were no significant differences between the two groups in the amount of tissue adhesive used， the number of puncture sites， and treatment costs （all P>0.05）. There were no significant differences between the two groups in rates of GOV-related and all-cause gastrointestinal rebleeding （all P>0.05）. Compared with the EUS-PCSS-D/P group， the EUS-PCSS-T group had a significantly lower number of treatment sessions required for GOV eradication （2.00 ［1.25 — 2.00］ vs 3.00 ［2.00 — 4.00］， Z=3.872， P<0.001）， with a higher two-session eradication rate （50.00% vs 17.86%， χ²=7.102， P=0.008） and a lower eradication rate for three or more sessions （23.33% vs 71.43%， χ²=15.326， P<0.001）. The subgroup analysis showed that history of endoscopic treatment and supplementary EIS did not affect the number of treatment sessions required for GOV regression （all P>0.05）， and the ordinal Logistic regression analysis showed that treatment grouping was an independent influencing factor for the number of treatment sessions required for GOV regression （odds ratio=0.32， 95% confidence interval： 0.15 — 0.68， P=0.007）. There was no significant difference in the incidence rate of adverse events between the two groups （P>0.05）， and no ectopic embolism was observed in the EUS-PCSS-T group. ConclusionThe EUS-PCSS-T procedure can significantly improve the eradication efficiency of GOV and reduce the number of treatment sessions； its efficacy is not affected by history of endoscopic treatment or supplementary EIS therapy， and it has a favorable safety profile.

ObjectiveTo investigate the potential mechanism of the Jianpi Yishen Huatan Formula （健脾益肾化痰方，JPYSHF） in treating squamous cell lung cancer through the LncRNA ALAL-1/USP4/HDAC2 signaling pathway. MethodsForty Sprague-Dawley （SD） rats were randomly divided into a control group and high-， medium-， and low-dose JPYSHF group with 10 rats in each group. Rats in the JPYSHF groups were administered JPYSHF concentrated liquid at doses of 45， 30， and 15 g/（kg·d） via intragastric gavage， respectively， while the control group received 10 ml/（kg·d） of normal saline， once daily for 10 consecutive days before preparation of drug containing serum. Human lung squamous carcinoma SK-MES-1 cells were divided into a control group and low-， medium-， and high-dose JPYSHF-medicated serum groups. The control group was cultured with 10% saline-containing serum， while the JPYSHF groups were cultured with 10% low-， medium-， or high-dose medicated serum. After 48 hours of incubation， flow cytometry was used to detect apoptosis rates， and a cell scratch assay was performed to evaluate migration areas at 0 h and 24 h to calculate migration rate. Additional SK-MES-1 cells were divided into control serum， JPYSHF-medicated serum （low-， medium-， high-） dose， LncRNA-silenced group （transfected with ALAL-1 siRNA）， USP4-inhibited group （treated with 35 μmol/L PR-619， a deubiquitinase inhibitor）， and HDAC2-inhibited group （treated with 60 μmol/L Vorinostat）. After 24 and 48 hours of culture， cell viability was assessed using the CCK-8 assay； LncRNA ALAL-1， USP4， and HDAC2 mRNA levels were quantified by qPCR after 24 hours； USP4 and HDAC2 protein levels were measured by Western Blot after 48 hours. ResultsCompared with the control serum group， the total apoptosis rate of cells in middle- and high-JPYSHF-medicated serum group significantly increased， and the cell migration rate of cells in the low-， middle- and high-JPYSHF-medicated serum group significantly decreased （P＜0.05 or P＜0.01）. The cell migration rate of the low-， medium- and high-JPYSHF-medicated serum groups decreased with the increase of concentration in a concentration-dependent manner （P＜0.05 or P＜0.01）. Compared with the control serum group at the same time， the cell viability at 24 h and 48 h significantly decreased in all groups （P＜0.05 or P＜0.01）. Compared with the low-JPYSHF-medicated serum group at the same time， the cell viability at 24 h and 48 h also decreased in the high-JPYSHF-medicated serum group and the LncRNA silencing group （P＜0.05）. Compared with the control serum group， the expression of USP4 and HDAC2 mRNA reduced in the low- and medium-dose JPYSHF-medicated serum groups and the USP4 inhibitor group， and the expression of LncRNA ALAL-1， USP4 and HDAC2 mRNA reduced in the high-dose JPYSHF-medicated serum group and LncRNA-silencing group， and HDAC2 mRNA expression reduced in the HDAC2 inhibitor group. USP4 and HDAC2 protein levels were reduced in cells of all groups except for USP4 protein level in HDAC2 inhibitor group （P＜0.05 or P＜0.01）. ConclusionJPYSHF-medicated serum inhibits proliferation and promotes apoptosis of human lung squamous carcinoma cells， and its mechanism of action may be related to its inhibition of the LncRNA ALAL-1/USP4/HDAC2 pathway， with best effect at a high concentration.

Objective To monitor the dynamic changes in liver stiffness and their correlation with clinical indicators among chronic hepatitis B virus (HBV) infected individuals in Wuwei City, Gansu Province, and to provide important evidence for the early detection and effective intervention of liver fibrosis (LF) progression. Methods Based on the Wuwei Hepatitis B Specialty Cohort, this study conducted annual serological and FibroScan ultrasonographic examinations for 3 882 chronic HBV-infected individuals. Over an average of 4 years of follow-up, the liver fibrosis outcome was monitored, and influencing factors were analyzed by constructing a logistic regression model. Results Among the 2 053 chronic HBV-infected individuals who completed at least one follow-up, baseline LF grades F0 to F4 were distributed as follows: 1 581 cases (77.0%), 164 cases (8.0%), 99 cases (4.8%), 110 cases (5.4%), and 99 cases (4.8%), respectively. Significant differences were observed among the five groups in terms of age, gender, smoking, antiviral treatment, liver function indicators, control attenuation index (CAP), and liver stiffness measurement (LSM) (P<0.05). After an average of 4 years of follow-up, 1 686 cases (17.9/100 person-years) showed no significant change in LF grade, 260 cases (2.8/100 person-years) demonstrated a decrease in LF grade, and 107 cases (1.1/100 person-years) exhibited an increase in LF grade. Stratified by baseline treatment status, among patients with chronic HBV infection who did not undergo treatment, baseline alanine aminotransferase (ALT) (OR=5.50, 95%CI：1.79-16.83, P=0.003) and LSM (OR=3.35, 95%CI：1.23-9.13, P=0.018) were identified as risk factors for LF progression. In contrast, among patients who underwent antiviral treatment, baseline aspartate aminotransferase (AST) (OR=2.23, 95%CI：1.41-3.53, P<0.001) and total bilirubin (TBIL) (OR=1.79, 95%CI：1.14-2.81, P=0.012) levels were identified as risk factors for LF progression. Conclusion LSM and liver function indicators, such as ALT, AST, and TBIL, are important influencing factors for LF progression. The monitoring of LSM and liver function indicators will be of great significance for the prevention and early diagnosis of liver cirrhosis.

Objective　To analyze the clinical characteristics and prognostic factors for clinical cure in chronic hepatitis B virus (HBV) infected patients with pegylated interferon-α-2b (PEG-IFN-α-2b) based therapy. Methods　This is a retrospective study. Chronic HBV infected patients receiving PEG-IFN-α-2b therapy were enrolled in Yuncheng Central Hospital affiliated to Shanxi Medical University between August 2020 and November 2023. Treatment-naïve patients received PEG-IFN-α-2b monotherapy, while nucleoside (acid) analogs (NAs)-experienced patients received PEG-IFN-α-2b add-on therapy. The study endpoint was hepatitis B surface antigen (HBsAg) negative in accompany with HBV DNA below the detection limit (course of treatment < 48 weeks) or treatment for 48 weeks. The general characteristics, virological variables, blood routine test, and liver function of patients were collected at baseline and study endpoint. Student’s t test or Mann-Whitney U test was used for comparison. The prognostic factors of clinical cure were examined using univariate and multivariate stepwise logistic regression models. Results　A total of 61 chronic HBV infected patients were enrolled, including 39 males and 22 females. The age were (39.13±7.53) years. Twenty-one cases were treatment-naïve, while 40 patients were NAs-experienced. Nineteen cases were positive for HBV DNA at baseline. The baseline HBsAg levels were 211.30(50.93, 2 110.00) IU/mL. Thirty-four patients achieved clinical cure at the study endpoint with 25.50 weeks of median course of PEG-IFN-α-2b treatment. Twenty-seven patients did not achieve clinical cure at the study endpoint, and the course of treatment was 48 weeks. Clinical cure group had significant lower baseline HBsAg level when compared with non-clinical cure group [78.66(19.54, 204.60) IU/mL vs 2 078.00(442.20, 4 237.00) IU/mL, P<0.001]. At the study endpoint, the white blood cell, platelet, red blood cell, hemoglobin levels were lower than those in baseline (P<0.05), while alanine aminotransferase and asparatate aminotransferase levels were higher than those in baseline (P<0.05). There were no remarkable differences in blood routine tests or liver function between clinical cure and non-clinical cure group at either baseline or study endpoint (P>0.05). Baseline low HBsAg level was a predictor for clinical cure in patients receiving PEG-IFN-α-2b therapy (OR=0.998, 95%CI: 0.998-0.999). No severe adverse events were happened during therapy. Conclusion　PEG-IFN-α-2b-based therapy was well-tolerant, and could achieve high rate of clinical cure in chronic HBV-infected patients who had low baseline HBsAg level.

Fire twinkling is the common method in cupping therapy. In the teaching materials of acupuncture and moxibustion, and the national standard, Standardized Manipulations of Acupuncture and Moxibustion-Part 5: Cupping Therapy, this cupping technique is operated by igniting an alcohol-soaked cotton ball held with a forceps, placing it inside the cup, taking it out after "turning around in several circles", and placing the cup on the selected area. Based on the clinical experience of chief physician LI Yan, a high-efficient and safe fire twinkling was developed. Clamping the middle part of the cotton ball with a holder, dipping it in 95% ethanol, and squeezing the cotton ball to ensure no ethanol drops left; holding the cup with the dominant hand and covering the ignited cotton ball vertically, removing the cup immediately when the ball touching the cup bottom. Such manipulation mode, "flame going in and out directly", can avoid the potential safety hazards such as residual ethanol left on the cup opening, overheating of cup opening and accidentally falling-off of the ignited cotton ball.

Infectious keratitis (IK) is a leading cause of blindness worldwide, primarily resulting from improper contact lens use, trauma, and a compromised immune response. The pathogenic microorganisms responsible for IK include bacteria, fungi, viruses, and Acanthamoeba. This review examines standard therapeutic agents for treating IK, including broad-spectrum empiric antibiotics for bacterial keratitis (BK), antifungals such as voriconazole and natamycin for fungal infections, and antiviral nucleoside analogues for viral keratitis (VK). Additionally, this review discusses therapeutic agents, such as polyhexamethylene biguanide (PHMB), for the treatment of Acanthamoeba keratitis (AK). The review also addresses emerging drugs and the challenges associated with their clinical application, including anti-biofilm agents that combat drug resistance and nuclear factor kappa-B (NF-κB) pathway-targeted therapies to mitigate inflammation. Furthermore, methods of Photodynamic Antimicrobial Therapy (PDAT) are explored. This review underscores the importance of integrating novel and traditional therapies to tackle drug resistance and enhance drug delivery, with the goal of advancing treatment strategies for IK.
