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.

Despite significant advances in the field of critical care medicine over the past three decades, veno-arterial extracorporeal membrane oxygenation (V-A ECMO) remains the primary temporary mechanical circulatory support modality for patients with acute severe circulatory failure. With the accumulation of clinical experience and the increasing maturity of operational techniques in V-A ECMO, its technical management—particularly hemodynamic management—has become a key factor influencing patient outcomes. To further improve patient survival, the Chinese Critical Care Ultrasound Study Group, in collaboration with the Hemodynamic Therapy of Critical Care Collaborative Group and the Critical Care Medicine Branch of the China International Exchange and Promotive Association for Medical and Health Care, organized experts in critical care medicine to develop the Consensus on Hemodynamic Management in Adult Veno-Arterial Extracorporeal Membrane Oxygenation (2026 Edition). Based on years of clinical experience and the latest evidence-based medical evidence, this consensus formulates 15 systematic recommendations covering the entire process of V-A ECMO, including initiation, management during support, and weaning, aiming to promote standardized application of hemodynamic management in V-A ECMO.

Diabetic macular edema(DME), a serious complication of diabetic retinopathy(DR), is a chronic condition caused by multiple factors. Throughout its progression, inflammatory factors and vascular endothelial growth factor(VEGF)play a critical role. Anti-VEGF drugs have shown significant effectiveness in the treatment of DME; however, some patients may experience persistent DME after injection or require frequent injections. Dexamethasone intravitreal implants(DEX implants)serve as a sustained-release implant characterized by a reasonable release profile and high bioavailability. They offer safe, effective, and prolonged anti-inflammatory effects, aiding in the repair of retinal barrier and reduction of exudation. To further enhance patients' visual quality, exploring the efficacy of DEX implants in combination with existing treatment regimens has great clinical significance. This review primarily discusses the research advancements in DEX implants, focusing on their pharmacological properties, indications for use, and their combination with existing drugs and treatment methods. It also evaluates the advantages and disadvantages of combination therapy or switching to DEX implants compared to current standard treatments, aiming to provide guidance for personalized treatment options for patients with DME.

AIM:To explore the role of stromal interaction molecule 1(STIM1)in the migration,invasion and angiogenesis of salivary adenoid cystic carcinoma(SACC),as well as its molecular mechanism.METHODS:Immu-nohistochemistry and Western blot were used to detect the expression level of STIM1 in human SACC tumor tissues and ad-jacent normal tissues.The TCGA database was analyzed to investigate the relationship between STIM1 expression and sur-vival in patients.A SACC-83 cell line with stable STIM1 overexpression(STIM1-OE)was established and divided into two groups:blank control(STIM1-Vec)group and STIM1-OE group.A nude mouse subcutaneous xenograft tumor model(n=6)was used to detect SACC growth.Transwell chamber assay,scratch test and dorsal root ganglion model were ap-plied to assess SACC migration and invasion.Immunohistochemistry was performed to detect the expression of CD34 and STIM1 in tumor tissues of nude mice.A nude mouse Matrigel plug model and human umbilical vein endothelial cell(HUVEC)tube formation assay were used to evaluate angiogenesis.Enzyme linked immunosorbent assay was employed to detect the levels of vascular endothelial growth factor(VEGF)and epidermal growth factor(EGF)in cell culture supernatants.RT-qPCR and Western blot were performed to detect the mRNA and protein expression levels of c-Myc,ribosomal protein L35(RPL35),ribosomal protein SA(RPSA),mitochondrial ribosomal protein L11(RPL11)and FAU ubiquitin like and ribo-somal protein S30 fusion(FAU).The STIM1-siRNA and RPL35-siRNA were transfected into SACC-83 cells,and the mi-gration,invasion and angiogenesis abilities of the cells were detected using the same methods as above.RESULTS:STIM1 was highly expressed in SACC,and the patients with high STIM1 expression had shorter survival time.In vivo,compared with STIM1-Vec group,STIM1-OE promoted tumor growth.In vitro,the number of migrating and invading SACC cells in STIM1-OE group was significantly increased,and the nerve invasion ability was also significantly en-hanced.Conversely,STIM1-siRNA significantly reduced the migration and invasion abilities of SACC cells.Additional-ly,STIM1-OE significantly promoted the expression of the vascular marker CD34,the secretion of VEGF and EGF,and the results of Matrigel plug and HUVEC tube formation assays indicated that STIM1-OE significantly promoted angiogene-sis.Silencing of RPL35 significantly inhibited SACC migration,invasion,and angiogenesis.RT-qPCR and Western blot results showed that the mRNA levels of RPL35,RPSA,MRPL11 and FAU were significantly increased(P<0.05),and the protein expression levels of STIM1,c-Myc and RPL35 were significantly increased(P<0.01).CONCLUSION:STIM1 drive the migration,invasion and angiogenesis of SACC by activating c-Myc/RPL35-mediated ribosome pathway.

Objective To evaluate the efficacy and safety of different surgical approaches for extracting high-positioned supernumerary teeth in the maxillary anterior midline region.Three surgical methods,the labial approach,the palatal approach,and a longitudinal incision beside the upper lip frenum were compared.Methods A total of 102 patients were recruited from the Department of Oral and Maxillofacial Surgery at the Affiliated Stomatological Hospital of Anhui Medical University between January and September 2024.They were randomly assigned via a random-digit table to three groups:the labial approach group(n=32),the palatal approach group(n=34),and the longitudinal incision beside the upper lip frenum group(n=36).Operation time,bone removal volume,post-operative midfacial swelling,degree of pain,and patient satisfaction across the three groups were recorded and compared.Results The average operation time in the labial approach group((20.50±3.02)min)and the longitudinal incision group((21.66±2.31)min)were both significantly shorter than that in the palatal approach group((29.19±3.40)min).In contrast,the palatal approach group demonstrated markedly lower postoperative swelling and pain scores(P＜0.05),along with the highest patient satisfaction,as reflected in the OHIP-14 scale.However,the palatal approach required the greatest bone removal volume,measuring(91.19±9.86)mm3.Conclusion Despite the palatal approach yielding superior outcomes in terms of postoperative pain control,swelling reduction,and patient satisfaction,it necessitated longer operation time and involved greater bone removal.Meanwhile,the labial approach and the longitudinal incision beside the upper lip frenum were comparable in all measured parameters,showing no statistically significant differences.Therefore,when extracting high midline impacted teeth in the maxillary anterior region,the choice of surgical approach should balance safety,minimal invasiveness,and patient satisfaction.

OBJECTIVE To build a Tibetan-language medication service platform based on"internet+"and evaluate its effect on improving medication compliance and safety of Tibetan patients with chronic disease.METHODS Medication guidance contents of commonly used drugs in the outpatient department were summarized,translated and recorded in Tibetan-language or video to form a"text-audio-video"multi-dimensional"internet+"Tibetan-language medication service platform.A total of 387 Tibetan outpatients with chronic disease in our hospital after the implementation of"internet+"Tibetan-language medication service platform(from January 2024 to June 2024)in our hospital were selected as the intervention group,and 387 Tibetan outpatients before the implementation(from January 2023 to June 2023)were selected as the control group.Patients in the control group received conventional window-based Chinese-language medication services,while patients in the intervention group received both conventional window-based Chinese-language medication service and"internet+"Tibetan-language medication service.The medication compliance of patients was evaluated using the 12-item Medication Compliance Scale.A six-level causality assessment was conducted as the principles for analyzing adverse drug reactions(ADR)set by the National Center for ADR Monitoring.Additionally,statistics were compiled on the occurrence of ADR that were assessed as"definite""probable"or"possible"in the causality assessment.RESULTS The proportion(31.0%)of patients with good medication compliance and compliance scores[39.0(37.0,42.0)]of patients in the intervention group were significantly better than control group[7.0%,21.0(19.0,23.0)](P＜0.05).There were no statistically significant differences in the incidence of various types of ADR or the overall incidence between the two groups(P＞0.05).CONCLUSIONS The"internet+"Tibetan-language medication service platform is constructed successfully;the service can effectively improve the medication compliance of Tibetan-language patients,but its effect on improving the medication safety of patients is limited.

Objective:To analyze the effects of preoperative renin-angiotensin system inhibitor (RASi) use on postoperative renal function and short-term and long-term prognosis in patients undergoing coronary artery bypass grafting (CABG).Methods:A retrospective cohort analysis was conducted. Based on the registration study data of CABG patients at Fuwai Hospital, Chinese Academy of Medical Sciences, the clinical data of adult patients who underwent CABG from January 2013 to December 2022 were analyzed. Preoperative use of RASi (PreRASi) was defined as receiving RASi treatment within 48 hours before surgery. Postoperative acute kidney injury (AKI) was defined using the diagnostic criteria of Kidney Disease: Improving Global Outcomes (KDIGO). Demographic characteristics, past medical history, comorbidities, preoperative medication, preoperative laboratory test results, specific information on surgical procedures, and postoperative treatment related data were extracted. The primary endpoint was the incidence of postoperative AKI. Secondary endpoints included in-hospital all-cause mortality and all-cause mortality within the longest follow-up period. According to whether RASi was used before surgery, the patients were divided into PreRASi group and No-PreRASi group. The baseline data of the two groups were balanced by propensity score matching (PSM). Logistic regression model and Cox proportional hazards model were used to assess the correlation between PreRASi and postoperative AKI and clinical outcomes, and analyze the subgroups of hypertension and heart failure with preserved ejection fraction (HFpEF) in the cohort.Results:A total of 33?884 patients who underwent CABG were included, with a mean follow-up duration of (3.0±2.4) years and the longest follow-up duration up to 8.5 years. There were 9?128 cases (26.94%) in the PreRASi group and 24?756 cases (73.06%) in the No-PreRASi group. The incidence of postoperative AKI in the PreRASi group was 47.61% (4?346 cases), compared to 52.37% (12?964 cases) in the No-PreRASi group. Two groups were matched with 5?094 patients each. Compared to the No-PreRASi group, both before and after PSM, PreRASi was associated with a reduction of risk of postoperative AKI [before PSM: odds ratio ( OR) = 0.834, 95% confidence interval (95% CI) was 0.793-0.877, P < 0.001; after PSM: OR = 0.875, 95% CI was 0.808-0.948, P = 0.001]. Subgroup analysis of hypertensive and HFpEF patients showed that PreRASi was associated with a decreased risk of postoperative AKI before and after PSM. The in-hospital mortality for the PreRASi and No-PreRASi groups were 0.61% (56 cases) and 0.49% (121 cases), respectively. Analysis of the overall cohort and subgroups with hypertension and HFpEF showed no correlation between PreRASi and in-hospital mortality or longest follow-up mortality. Conclusion:The perioperative use of RASi can reduce the risk of postoperative AKI in patients undergoing CABG, has a certain renal protective effect, but is not associated with short-term or long-term death risk after surgery.

AIM:To investigate the effects of sodium hydrosulfide(NaHS)on hexokinase 2(HK2)-nucleo-tide-binding oligomerization domain-like receptor protein 3(NLRP3)-gasdermin D(GSDMD)pathway and pyroptosis in-duced by lung ischemia/reperfusion(I/R)in rats.METHODS:Male Sprague-Dawley rats were divided into 6 groups:control group,control+NaHS group,I/R group,low-dose NaHS+I/R(L+I/R)group,medium-dose NaHS+I/R(M+I/R)group,and high-dose NaHS+I/R(H+I/R)group,with 6 rats in each group.The NaHS was administered via intraperi-toneal injection at 1.5 mL,30 min before modeling.The left lung tissues were collected 30 min after ischemia and 1 h af-ter reperfusion,and the wet/dry weight ratio and total lung water content were recorded.Hematoxylin-eosin(HE)staining was used to examine lung tissue morphological changes.The levels of malondialdehyde(MDA),myeloperoxidase(MPO)and lactate in lung tissues were measured with test kits.ELISA was employed to determine the levels of interleukin-1β(IL-1β)and IL-18.The expression of glycolysis-and pyroptosis-related indicators was analyzed by Western blot,qRT-PCR and immunofluorescence staining.RESULTS:Compared with control group,the rats in NaHS group showed no signifi-cant differences in all laboratory tests(P>0.05).The rats in I/R group exhibited significant lung injury,oxidative stress,increased lactate level,and up-regulated glycolysis and pyroptosis(P<0.05 or P<0.01).Compared with I/R group,the indicators in L+I/R group showed a downward trend(P<0.01)or no difference(P>0.05),while those in M+I/R group dis-played a significant reduction(P<0.05 or P<0.01).However,the indexes in H+I/R group exhibited no significant dif-ferences in these tests(all P>0.05).CONCLUSION:A moderate dose(56 μmol·L-1·kg-1)of NaHS mitigated the oc-currence of pyroptosis by inhibiting the HK2-NLRP3-GSDMD pathway,thus contributing to the attenuation of lung I/R in-jury in rats.
