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.

AIM: To evaluate the visual function and optical quality in adults aged 80y and older following the bilateral implantation of zonal refractive multifocal intraocular lens(IOL, LS-313 MF30).METHODS: A single-center, non-randomized, prospective clinical trial was conducted, involving cataract patients aged 80 y and older. Patients received bilateral implantation of the LS-313 MF30 or CT Asphina 409MP, based on personal preference. Postoperative assessments included uncorrected and corrected visual acuity at distance, intermediate, and near ranges, as well as defocus curve. Subjective evaluations were performed using the visual function(VF-14)questionnaire, spectacle independence rates, and patient satisfaction surveys. Photic phenomena such as glare, halos, and starbursts were also analyzed.RESULTS: The MF30 group(16 eyes from 8 participants, 85.38±2.56 y)exhibited superior uncorrected and corrected intermediate and near visual acuity compared to the 409MP group(26 eyes from 13 participants, 85.77±2.20 y), while distance visual acuity was comparable between groups. The defocus curve of the MF30 group revealed two peaks at 0.00 D and -3.00 D, indicating a broader depth of focus. Patients in the MF30 group reported higher rates of spectacle independence and greater satisfaction. While photic phenomena such as glare(28.6% vs 18.5%, P=0.584), starburst(9.5% vs 3.7%, P=0.567)and halos(23.8% vs 11.11%, P=0.438)were more prevalent in the MF30 group, they were generally mild and did not significantly impact daily activities.CONCLUSION: Zonal refractive multifocal IOLs provide elderly patients with improved distance and near vision, greater spectacle independence, and greater satisfaction. Although photic phenomena were slightly more frequent with MF30, they are generally reported as non-disruptive and do not affect their daily life compared to monofocal IOLs.

ObjectiveThis paper aims to explore the in vitro anti-psoriasis activity and potential mechanism of Kangfuxin liquid （KFX liquid）， providing experimental evidence for the anti-psoriasis effect of KFX liquid. MethodsFirstly， the uninduced human immortalized keratinocyte cells （HaCaT cells） were divided into seven groups， namely the control group and KFX liquid groups with different doses （5， 10， 20， 40， 80， 160 g·L^-1）. After being treated with different concentrations of KFX liquid， the effect of KFX liquid on the normal cell proliferation was detected by using the cell counting kit-8 （CCK-8） method. Secondly， the uninduced HaCaT cells were divided into six groups， namely the control group and recombinant human interleukin-7A （rh-IL-7A） groups with different doses （5， 10， 50， 100， 120 g·L^-1）. After being treated with different concentrations of recombinant human interleukin-17A （rh IL-17A） liquid， the effect of rh IL-17A on cell proliferation was detected. The optimal induction concentration was screened. Then， normal HaCaT cells were divided into a control group and KFX liquid groups with different doses （5， 10， 20， 40， 80， 160 g·L^-1）. Except for the control group， the other groups established psoriasis cell models with the optimal induction concentration of rh IL-17A. After being treated with different concentrations of KFX liquid， the effects of KFX liquid on the psoriasis-like HaCaT cell proliferation were investigated. Finally， the uninduced HaCaT cells were divided into six groups， namely the control group， rh IL-17A group， methotrexate （MTX） group， and KFX liquid groups with different doses （20， 40， 80 g·L^-1）. Except for the control group， the other groups used the optimal induction concentration of rh IL-17A to establish psoriasis cell models. After being treated with different drugs， the cell migration levels were detected through scratch assays， and real-time quantitative polymerase chain reaction （Real-time PCR） was used to detect the relative mRNA expression levels of Ki-67 antigen （Ki67）， S100 calcium-binding protein A7 （S100A7）， S100 calcium-binding protein A8 （S100A8）， and S100 calcium-binding protein A9 （S100A9）， thereby comprehensively evaluating the in vitro anti-psoriasis activity of KFX liquid. By detecting the relative mRNA expression levels of interleukin-1β （IL-1β）， interleukin-6 （IL-6）， and chemokine-20 （CXCL-20） inflammatory-related factors in psoriasis-like HaCaT cells and the protein expression levels of Janus kinase 3 （JAK3）， phosphorylated Janus kinase 3 （p-JAK3）， signal transducer and activator of transcription 3 （STAT3）， and phosphorylated signal transducer and activator of transcription 3 （p-STAT3）， the mechanism was explored. ResultsCompared with that of control group， when treated with 80 g·L^-1 KFX liquid for 72 h （P<0.05） and at different times with 160 g·L^-1 KFX liquid， the HaCaT cell proliferation activity was significantly affected （P<0.01）， while the other concentrations of KFX liquid had no significant differences in cell morphology and cell proliferation activity at different times， indicating that the KFX liquid is relatively safe for HaCaT cells and has no obvious toxic side effects. Compared with that of control group， when treated with different concentrations of rh IL-17A for 24 h， the HaCaT cell proliferation activity was significantly enhanced， and the cell activity was the strongest when the concentration was 100 μg·L^-1 （P<0.05）， with a density close to 100% and intact cell morphology， indicating that 100 μg·L^-1 is the optimal concentration for inducing HaCaT cell proliferation. The results of the KFX liquid treatment on rh IL-17A-induced psoriasis-like cells show that the KFX liquid not only effectively inhibits the rh IL-17A-induced psoriasis-like HaCaT cell proliferation activity （P<0.01）， but also significantly reduces the migration ability of rh IL-17A-induced psoriasis-like HaCaT cells （P<0.01）， and the relative mRNA expression levels of Ki67， S100A7， S100A8， and S100A9 （P<0.01）. Moreover， the KFX liquid can significantly reduce the relative mRNA expression levels of IL-1β， IL-6， and CXCL-20 in rh IL-17A-induced psoriasis-like cells （P<0.01）， and significantly inhibit the phosphorylation levels of JAK3 and STAT3 proteins （P<0.05， P<0.01）. ConclusionThe KFX liquid has no obvious toxicity to uninduced HaCaT cells. It can inhibit rh IL-17A-induced psoriasis-like HaCaT cell proliferation， reduce the cell migration ability， and has good in vitro anti-psoriasis activity. Its action mechanism may be related to downregulating the expression levels of inflammation-related cytokines in the JAK3/STAT3 signaling pathway and inhibiting the phosphorylation levels of JAK3 and STAT3 proteins.

ObjectiveTo construct an interleukin-9 （Il9） gene knockout mouse model on a C57BL/6N background， establish a reliable genotyping method， and provide a standardized animal model for investigating Il9-related immune mechanisms and diseases. MethodsIl9 knockout mouse strain （C57BL/6N-Il9^em1Cya） was generated using conventional gene knockout technology. The method for DNA extraction from mouse tails was optimized to ensure template quality. Two sets of specific primers （F1/R1 and F1/R2） were designed to amplify target fragments by PCR， and mouse genotypes were determined by agarose gel electrophoresis. Specifically， primer pair F1/R1 targeted the knockout sequence with an expected product of 465 bp， while F1/R2 targeted the wild-type sequence with an expected product of 703 bp. Subsequently， Western blot was performed to verify the knockout efficiency of Il9 in primary immune cells and key organs of the offspring mice， and flow cytometry was used to assess the effects of Il9 deficiency on the function of the immune system in major immune cell populations. ResultsIl9 knockout mice were successfully bred and genotyped. PCR identification showed that homozygous mice （-/-） exhibited only a 465 bp band， wild-type mice （+/+） displayed only a 703 bp band， and heterozygous mice （+/-） showed both bands simultaneously. Meanwhile， Western blot analysis revealed significantly decreased IL-9 expression in various organs of the offspring mice （P<0.001）. Flow cytometric results demonstrated that Il9 deficiency exerted no obvious effects on the proportions of peripheral blood lymphocytes， splenic lymphocytes， and peritoneal macrophages. ConclusionAn Il9 gene knockout mouse model on a C57BL/6N background is successfully constructed. The established PCR genotyping system is highly efficient and accurate， which can effectively distinguish mice of different genotypes. This model provides a stable and reliable experimental basis for subsequent functional studies of Il9 and exploration of the mechanisms underlying Il9-related diseases.

ObjectiveTo construct a chimeric antigen receptor macrophage （CAR-M） targeting interleukin-13 receptor α （IL-13Rα） and intracellular domain integration， which can double activate the signal adaptor protein OX40L of macrophages and T cells. MethodsThe CAR molecule targeting IL-13Rα （IL-13Rα-OX40L-CAR） with OX40L as the intracellular signal domain was designed and synthesized， and it was cloned into the adenovirus expression vector. After THP-1 cells were induced to differentiate into macrophages （THP-1-M） by phorbol ester， the cells were infected with recombinant adenovirus to construct THP-1 macrophages stably expressing green fluorescent protein （GFP） labeled anti-IL-13RαCAR. The expression efficiency of CAR molecules was monitored by flow cytometry. The empty vector group was used as the negative control， the CD3ζ group was used as the positive control， and the CD3ζ-OX40L group was used as the experimental group. The phagocytic function of macrophages in each group on IL-13Rα high expression glioma cells （U251） and low expression glioma cells （T98G） was detected by in vitro co-culture experiments. ResultsCAR adenovirus was efficiently transfected into THP-1-M to obtain anti-IL-13RαCAR-M. After co-cultured with glioma cells with different expression levels of IL-13Rα， the results of flow cytometry showed that there was no significant difference among the three groups for T98G cells with low expression of IL-13Rα. After co-culture with U251 cells with high expression of IL-13Rα， the CD3ζ group showed enhanced phagocytosis compared with the empty vector group （P<0.05）. Compared with the CD3ζ group， the phagocytosis ability of the CD3ζ-OX40L group was further enhanced （P<0.05）. ConclusionAnti-IL13Rα- OX40L-CAR-M is successfully constructed by constructing IL-13Rα-OX40L-CAR adenovirus and transfecting PMA-induced differentiated THP-1-M. It can engulf glioma cells with high expression of IL-13Rα by specific targeting， and shows activation of intracellular domain superior to traditional CD3ζ.

ObjectiveTo obtain a construct chimeric antigen receptor macrophages （CAR-M） targeting disialoganglioside GD2 （GD2） and harboring the intracellular domain of macrophage-specific activating signaling adaptor protein DNAX-activating protein 12 （DAP12）. MethodsA CAR molecule targeting GD2 with the DAP12 intracellular domain as the signaling module ［Anti-GD2 CAR （DAP12）］ was designed， synthesized， and cloned into an adenoviral vector. This virus was used to infect PMA-differentiated THP-1 macrophages to construct green fluorescent protein （GFP）-labeled Anti-GD2 CAR THP-1 cells. CAR expression was confirmed using live-cell imaging. In vitro co-culture assays were performed to evaluate the phagocytic function of empty， Anti-GD2 CAR-M （CD3ζ）， and Anti-GD2 CAR-M （DAP12） groups against glioma cells with high （T98G） and low （U251） GD2 expression. ResultsThe CAR adenovirus efficiently transduced THP-1 macrophages， resulting in successful generation of Anti-GD2 CAR-M. Flow cytometry analysis following co-culture with glioma cells showed that compared to the empty group， the Anti-GD2 CAR-M （CD3ζ） group exhibited significantly enhanced phagocytosis （P<0.05）. Furthermore， compared to the Anti-GD2 CAR-M （CD3ζ） group， the Anti-GD2 CAR-M （DAP12） group demonstrated a further increase in phagocytic capacity specifically against GD2-high T98G cells （P<0.05）. ConclusionAnti-GD2 CAR-M （DAP12） cells are successfully established by transducing PMA-differentiated THP-1-M with recombinant Anti-GD2 CAR （DAP12） adenovirus. The engineered CAR-M can specifically target phagocytose glioma cells with high GD2 expression.

ObjectiveTo obtain stably transfected chimeric antigen receptor macrophages （CAR-M） targeting disialosylganglioside （GD2） based on the constitutive expression of myeloid differentiation factor 88 （MYD88）. MethodsAn Anti-GD2 CAR adenoviral vector incorporating the CD3ζ （cluster of differentiation 3 zeta chain）-MYD88 fusion construct was designed and constructed. THP-1-derived macrophages （THP-1M）， induced by phorbol 12-myristate 13-acetate （PMA） differentiation， were infected with this adenovirus to generate Anti-GD2 CAR THP-1 cells bearing a green fluorescent protein （GFP） tag. CAR expression was monitored using a live-cell imaging system. The phagocytic function of Empty CAR-M， Anti-GD2 CAR-M（CD3ζ）， and Anti-GD2 CAR-M（CD3ζ-MYD88） groups against glioma cells was evaluated in vitro through co-culture experiments， and their polarization status was also analyzed. ResultsCAR adenovirus successfully transfected THP-1 to obtain Anti-GD2 CAR-M. After co-culture with glioma cells， flow cytometry results showed that compared with the Empty CAR-M group and the Anti-GD2 CAR-M（CD3ζ） group， the Anti-GD2 CAR-M（CD3ζ-MYD88） group exhibited enhanced phagocytosis against T98G cells with high GD2 expression （P<0.05） and also showed upregulation of CD86 （P<0.05）. Compared with the Empty CAR-M group and the Anti-GD2 CAR-M（CD3ζ） group， the Anti-GD2 CAR-M（CD3ζ-MYD88）CAR-M group exhibited enhanced phagocytosis against T98G cells with high GD2 expression （P<0.05） and also showed upregulation of CD86 （P<0.05）， and the expression of inflammatory cytokines interleukin （IL）-6 and IL-12 was increased in this group （P<0.05）. ConclusionThis study successfully constructed Anti-GD2 CAR-M cells and verified their phagocytic activity， demonstrating that constitutive expression of MYD88 can promote inflammatory polarization of CAR-M. This provides a potential structural modification approach for the development of pro-inflammatory CAR-M.

Objective To investigate the predictive value of the combined tumor burden score (TBS) and platelet-albumin-bilirubin (PALBI) score model for postoperative tumor recurrence in liver transplant recipients with hepatocellular carcinoma (HCC). Methods The general information of 158 recipients diagnosed with HCC and underwent liver transplantation at the 900th Hospital of the Joint Logistics Support Force of the Chinese People's Liberation Army from 2008 to 2021 was collected. Lasso regression analysis combined with multivariate Cox regression analysis were used to identify independent risk factors for postoperative tumor recurrence after liver transplantation with HCC. A nomogram prediction model was constructed based on variables selected by Lasso regression analysis, and the predictive performance of the model was verified by calibration curve and clinical decision curve. The optimal cut-off values for postoperative tumor recurrence in liver transplant recipients with HCC were determined by receiver operating characteristic (ROC) curve, and Kaplan-Meier analysis was used to compare survival differences among different groups. Results Among the 158 liver transplant recipients with HCC, 82 experienced tumor recurrence, with a recurrence rate of 51.9% and a median tumor-free survival time of 10 (4, 25) months. Results of Lasso regression analysis and multivariate Cox regression analysis showed that alpha-fetoprotein (AFP) ≥400 ng/mL, TBS and PALBI score were all independent risk factors for postoperative tumor recurrence in liver transplant recipients with HCC (all P<0.05). The combined high TBS-high PALBI score showed the highest predictive value (hazard ratio 6.909, 95% confidence interval 3.067-15.563, P<0.001). A nomogram prediction model was constructed based on six variables selected by Lasso regression analysis. Calibration curve showed good consistency between the model's predicted results and the ideal curve. Decision curve analysis indicated that the nomogram prediction model provided the highest clinical benefit for predicting 1-year tumor-free survival after liver transplantation with HCC. Time-dependent ROC curves at 1, 3 and 5 years after surgery showed that TBS-PALBI model had good predictive performance, with no significant difference in area under the curve (AUC) compared with TBS-PALBI-AFP model. The optimal cut-off values for predicting postoperative tumor recurrence were determined by ROC curve, with a PALBI score cut-off of −2.334 and a TBS cut-off of 5.305. Recipients were divided into a low TBS-low PALBI score group (n=47) and a low/high TBS-low/high PALBI score group (at least one score was high) (n=111). Kaplan-Meier survival analysis showed that the low TBS-low PALBI score group had a higher tumor-free survival rate than the low/high TBS-low/high PALBI score group, with a significant difference (P<0.05). Conclusions TBS-PALBI model provides a novel, simple and effective tool for assessing the prognosis of liver transplant recipients with HCC. The nomogram model constructed based on this has significant advantages in predictive performance and may serve as a reference for guiding individualized treatment plans and improving clinical outcomes.
