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.

Background and Aims:Papillary thyroid carcinoma(PTC)is the most common endocrine malignancy,yet the molecular mechanisms underlying its invasion and metastasis remain unclear.This study aimed to investigate the role of the transcription factor ETV4 in PTC and its regulatory relationship with cadherin-3(CDHP/CDH3).Methods:Expression levels of ETV4 and CDHP were analyzed using TCGA and GTEx databases,and further validated in normal thyroid cells and multiple PTC cell lines by qRT-PCR and Western blot analysis.ETV4-knockdown models were established using siRNA,and changes in CDHP expression and cellular behaviors were assessed by qRT-PCR,Western blot,CCK-8,wound healing,and Transwell assays.Results:Bioinformatics analysis revealed significantly higher expression of ETV4 and CDHP in PTC tissues compared to normal thyroid tissues(P<0.001).Correlation analysis demonstrated a strong positive association between ETV4 and CDHP expression(R2>0.5,P<0.01).In vitro assays confirmed that both ETV4 and CDHP were upregulated in all tested PTC cell lines at the mRNA and protein levels(all P<0.05).Knockdown of ETV4 led to marked reduction of CDHP expression(P<0.05),accompanied by decreased cell proliferation,migration,and invasion as demonstrated by CCK-8,wound healing,and Transwell assays(all P<0.05).Conclusion:ETV4 may transcriptionally upregulates CDHP to promote proliferation,migration,and invasion of PTC cells.The ETV4/CDHP axis may serve as a novel biomarker and potential therapeutic target in PTC.

Objective To evaluate the efficacy of the manual cyclotorsion compensation method based on the obser-vation screen in the correction of with-the-rule astigmatism during small incision lenticule extraction(SMILE).Methods This prospective study enrolled 40 patients who underwent SMILE and another 40 patients who underwent Q-value-guided femtosecond laser-assisted laser in situ keratomileusis(FS-LASIK)at the Ophthalmology Center of the Second Affiliated Hospital of Nanchang University from April to September 2024.Through the random number method,one eye of each pa-tient who underwent SMILE was assigned to the manual cyclotorsion compensation group(the cyclotorsion group,40 eyes),while the contralateral eye was assigned to the non-cyclotorsion group(the non-cyclotorsion group,40 eyes).Meanwhile,one eye of each patient who underwent FS-LASIK was randomly selected for the FS-LASIK group(40 eyes).The age,uncorrected distance visual acuity(UDVA),spherical power,cylindrical power,spherical equivalent(SE),and corrected distance visual acuity(CDVA)were recorded before surgery and 3 months after surgery,respectively.Astigma-tism was subjected to Alpins vector analysis,and the indicators for assessing astigmatism included target-induced astigma-tism(TIA),surgically-induced astigmatism(SIA),difference vector(DV),correction index(CI),success index(IOS),angle of error(AE),and absolute value of angle of error(|AE|).Results Before surgery,there was no significant difference in age,spherical power,cylindrical power,SE,and CDVA among the cyclotorsion group,the non-cyclotorsion group,and the FS-LASIK group(all P＞0.05).At 3 months after surgery,the cyclotorsion group showed better UDVA and lower cylindrical power than the non-cyclotorsion group,with statistically significant differences(both P＜0.05);howev-er,there was no significant difference in CDVA,spherical power,and SE between the two groups(all P＞0.05).Besides,there was no significant difference in UDVA,CDVA,or refractive parameters between the cyclotorsion and FS-LASIK groups(all P＞0.05).The Alpins vector analysis of astigmatism 3 months after surgery revealed better SIA,CI,IOS,and|AE|in the cyclotorsion group compared with the non-cyclotorsion group,with statistically significant differences(all P＜0.05);however,there was no significant difference in TIA,DV,and AE between the two groups(all P＞0.05).No signifi-cant differences were found between the cyclotorsion and FS-LASIK groups in any astigmatism vector parameter(all P＞0.05).The linear regression analysis results indicated a high linear correlation between TIA and SIA in all groups.Conclu-sion The manual cyclotorsion compensation method based on the observation screen in the correction of with-the-rule astigmatism during SMILE is comparable to Q-value-guided FS-LASIK and superior to the conventional central tear film marking method in SMILE.

Aim To examine the pathogenesis of disul-fide death gene in vascular dementia(VD)by bioin-formatics analysis of disulfide death differentially ex-pressed genes(DEGs)combined with experimental verification.Methods The death DEGs of disulfide were screened and their correlation was analyzed.The VD patients data in the data set were analyzed by clus-tering and typing and gene set variation.The clustering risk of DEGs was tested with a nomogram model,and the optimal learning model was predicted.After the es-tablishment of VD rat model,water maze test,HE stai-ning and RT-qPCR detection were performed to verify the results of health information.Results Four DEGs including SLC7A11 were obtained,which had antago-nistic or synergistic interaction with each other.The genetic data could be divided into two subtypes with significant differences.After typing,VD disulfide DEGs were mainly concentrated in GnRH signaling pathways.The accuracy of the nomogram prediction model was high.Generalized linear was the best ma-chine learning model.Compared with the sham opera-tion group,the escape latency of rats in the model group was prolonged,the number of crossing platforms decreased,the relative mRNA expression levels of Slc3a2 and Slc7a11 decreased,and LRPPRC in-creased.Conclusions SLC7A11 and other disulfide death DEGs and its related GnRH signaling pathway may be an important part of the pathogenesis of VD di-sulfide death.SLC3A2,LRPPRC and SLC7A11 can be used as characteristic genes in the regulation of VD by disulfide death,which may affect VD progression through the regulation of disulfide death.

Objective:To investigate the effect of FOXQ1 expression on chemoresistance in colorectal cancer and analyze its regulatory role in SIRT1 expression and p53 deacetylation under DNA damage response(DDR)condi-tions.Methods:qRT-PCR was used to detect FOXQ1 mRNA expression levels in SW620 cells and SW620 cells stimulated with cisplatin(CDDP).Lentiviral vectors were constructed for FOXQ1 overexpression and RNA interference.The cells were divided into three groups:FOXQ1 overexpression group(oe-FOXQ1),FOXQ1 RNA interference group(sh-FOXQ1),and a control group transfected with an empty vector(NC).The half-maximal inhibitory concentration(IC50)of CDDP in each group was determined using the CCK-8 assay.Apoptosis level and cell viability were assessed using the Annexin V-APC/7-ADD apoptosis detection kit and Calcein/PI staining.Western blot analysis was performed to evaluate the effect of FOXQ1 on SIRT1 expression and acetylated p53 levels.The SIRT1 pathway inhibitor(S)-Selisi-stat was introduced to observe changes in p53 acetylation levels.Results:Compared to normal colon tissues,FOXQ1 expression was significantly upregulated in SW620 cells(P＜0.05),and low-dose CDDP stimulation further en-hanced its expression(P＜0.05).After 24 hours of CDDP treatment,the IC50 values for the oe-FOXQ1,sh-FOXQ1,and NC groups were 58.3 μmol/L,36.4 μmol/L,and 43.7 μmol/L,respectively,with statistically significant differences among the groups(P＜0.05).Compared to the NC group,the oe-FOXQ1 group showed a decrease in late apoptotic cell count(P＜0.05),while the sh-FOXQ1 group exhibited an increase(P＜0.05).Cytotoxic fluorescence staining re-vealed that the proportion of cell death was lower in the oe-FOXQ1 group and higher in the sh-FOXQ1 group com-pared to the NC group(P＜0.05).Protein expression analysis showed that FOXQ1 and SIRT1 levels were higher in the oe-FOXQ1 group and lower in the sh-FOXQ1 group compared to the NC group(P＜0.05).FOXQ1 overexpression pro-moted p53 deacetylation,while the addition of the SIRT1 pathway inhibitor(S)-Selisistat restored p53 acetylation levels(P＜0.05).Conclusion:FOXQ1 promotes p53 deacetylation by upregulating SIRT1 expression,thereby inhibiting DDR-induced apoptosis.

Objective To understand the current situation of healthcare-associated infection(HAI)in China,pro-vide data support and decision-making basis for formulating scientific and effective strategies for HAI prevention and control.Methods A nationwide cross-sectional survey on HAI was conducted among various types and levels of medical institutions in China according to a unified protocol of bedside surveys and case investigations.Results In 2024,a total of 5 736 medical institutions and 2 751 765 patients were surveyed.Among them,34 889 HAI cases were identified,with a prevalence rate of 1.27％.The number of HAI episodes was 38 032,and case prevalence rate was 1.38％.The prevalence rate of HAI in medical institutions in different regions of China ranged from 0.66％to 2.35％.Among medical institutions of different scales,those with a bed capacity of ≥900 had the high-est incidence of HAI,reaching 1.65％.The most common infection site was the lower respiratory tract(44.66％),followed by the urinary tract(12.94％),surgical site(9.32％),upper respiratory tract(7.02％),and bloodstream infection(5.78％).The top 3 departments with the highest HAI rates were the general intensive care unit(10.02％),department of neurosurgery(5.51％),and department(group)of hematology(5.34％).A total of 23 238 strains of HAI pathogens were detected,with 10 714 strains(46.10％)from lower respiratory tract speci-mens.The top 5 detected strains were Klebsiella pneumoniae(14.76％),Pseudomonas aeruginosa(13.33％),Escherichia coli(12.79％),Acinetobacter baumannii(9.23％),and Staphylococcus aureus(7.88％).231 944 pa-tients underwent class Ⅰ incision surgery were monitored,with 1 647 cases experienced surgical site infection,and the prevalence rate of surgical site infection was 0.71％.The number of patients who should undergo pathogen de-tection(patients receiving therapeutic and therapeutic combined prophylactic antimicrobial agents)was 715 179,while the actual number was 480 492,with a pathogen detection rate of 67.18％.425 225 patients received patho-genic detection before treatment,with a detection rate of 59.46％.Conclusion The overall HAI prevalence in Chi-na is lower,showing disparities among medical institutions of different regions and scales.Therefore,precise imple-mentation of measures is necessary for HAI prevention and control,with a focus on high-risk institutions and high-risk departments,key areas,and critical procedures.All levels of medical institutions should continuously reduce the incidence of HAI by strengthening monitoring,standardizing the use of antimicrobial agents,and reinforcing basic HAI prevention and control measures.

OBJECTIVE: To investigate the early clinical efficacy, safety, and application value of one-hole split endoscopy (OSE)-assisted transforaminal lumbar interbody fusion(TLIF) in the treatment of lumbar degenerative diseases. METHODS: A retrospective analysis was conducted on 17 patients with lumbar degenerative diseases who underwent OSE-assisted TLIF between June 2023 and June 2024. There were 10 males and 7 females, with a mean of (55.30±6.52) years old ranging 43 to 65 years. The disease duration ranged from 3 to 36 months with a mean of(12.4±13.3) months. The disease distribution was as follows:lumbar disc herniation (7 cases), lumbar spinal stenosis (5 cases), and lumbar spondylolisthesis (2 cases). Operative time, incision length, intraoperative blood loss, number of intraoperative fluoroscopic exposures, time to ambulation, postoperative hospital stay, and complications were recorded. The dural sac area at the affected segment, visual analogue scale (VAS) for low back pain and leg pain, and Oswestry disability index (ODI) were recorded preoperatively and postoperatively. The modified MacNab criteria were used to evaluate the surgical outcome at the final follow-up. RESULTS: All 17 patients successfully underwent surgery and were followed up for 3 to 15 months with a mean of (8.4±3.3) months. The operative time was 120 to 200 minutes with a mean of (143.2±22.0) minutes, the incision length on the decompression side was 1.80 to 4.00 cm with a mean of (2.56±0.65) cm, intraoperative blood loss was 50 to 300 ml with a mean of (161.2±72.5) ml, the number of fluoroscopic exposures was 15 to 38 with a mean of (23.4±6.5), time to ambulation was 24 to 72 hours with a mean of (49.2±11.9) hours, and postoperative hospital stay was 3 to 9 days with a mean of (4.9±1.5) days. Two patients developed transient lower limb pain and numbness, which completely resolved with conservative treatment. The postoperative dural sac area was (121.47±14.90) mm², which was significantly larger than the preoperative area (51.47±7.69) mm²(P<0.001). The VAS for low back pain were (6.23±1.64), (2.94±1.43), and (1.94±0.75) at preoperation, 3 days postoperation, and final follow-up, respectively;the VAS for leg pain were (7.06±1.43), (2.35±1.17), and (2.06±0.90) at the same time points. The VAS at all postoperative time points were significantly lower than preoperative scores (P<0.001). The ODI at final follow-up was (25.29±8.15)%, which was significantly better than the preoperative ODI of(82.35±5.16)%(P<0.001). At the final follow-up, the MacNab surgical outcome was excellent in 11 cases, good in 4 cases, and fair in 2 cases. CONCLUSION OSE-assisted TLIF is an effective, safe, and minimally invasive technique with a gentle learning curve for the treatment of lumbar degenerative diseases, capable of effectively relieving symptoms and improving function.
