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:In recent years,postmenopausal osteoporosis has been widely concerned by the society.With the gradual deepening of the research on animal models,animal models have become an important means of modern traditional Chinese medicine research as well as the experimental basis.Therefore,it is particularly important to understand the current status,hotspots,and development trend of the research on animal models.OBJECTIVE:To analyze the research status,hotspots,and development trend of animal models of postmenopausal osteoporosis at home and abroad,and to provide a certain theoretical foundation and reference basis for subsequent research.METHODS:Using"Subject=Postmenopausal osteoporosis AND Subject line=Mouse+Rabbit+Dog+Pig+Sheep+Monkey+Fish+Laboratory animals+Animal experimentation"in Chinese as the search formula,we searched for relevant literature published from January 1,1999 to October 1,2023 in CNKI and WanFang databases.Meanwhile,the articles published from January 1,1999 to October 1,2023 in the Web of Science Core Collection database were searched using"TS=(Postmenopausal osteoporosis)AND TS=(mouse OR mice OR rat OR rabbit OR dog OR swine OR pig OR sheep OR monkey OR fish OR flies OR"laboratory animal"OR"experiment animal"as the search formula.CiteSpace software was applied to visualize and analyze the authors,institutions,countries,keywords,and literature co-citations.RESULTS AND CONCLUSION:(1)After analyzing and screening,1 238 documents were included in the CNKI and WanFang databases,and 3 419 documents were included in the Web of Science Core Collection database.The overall number of articles issued since 1999 has been on an upward trend,with the highest research centrality in the United States,the highest number of articles issued in China.Moreover,the institution with the highest research centrality is the University of California.(2)After removing the keywords directly related to the article topics and synthesizing the co-occurrence frequency and centrality,"biomechanics,""Zuo Gui Wan,""alendronate,""breast cancer,"and"biochemical indicators"are in the core of the research field.(3)According to the analysis of co-citations,among the top 10 cited documents,5 of them are related to the treatment measures and clinical efficacy of postmenopausal osteoporosis.(4)Based on the analysis of keywords and co-cited literature,investigations on osteoblast formation and the mechanism of bone formation,the mechanism of metabolomics,the treatment of traditional Chinese medicine,signaling pathway,parathyroid hormone treatment,and sclerostin antibody treatment are the hot research topics now and the future research trends.

Objective:To investigate the related factors of cognitive impairment in middle-aged and old-aged patients with type 2 diabetes mellitus(T2DM).Methods:A total of 970 patients with T2DM(585 middle-aged group and 385 old-aged group)were selected from residents of a large community in Beijing from September to December 2018.The Mini-Mental State Examination(MMSE)was used to assess the cognitive func-tion.Multivariate logistic regression was used to analyze the related factors.Results:The detection rates of cognitive impairment were 12.0％and 13.5％in middle-aged and old-aged patients with T2DM,respectively.Among mid-dle-aged patients with T2DM,work(OR=0.22,95％CI:0.03-0.77)and education at the junior college or un-dergraduate level and above(OR=0.18,95％CI:0.04-0.55)were protective factors for cognitive impair-ment.Myocardial infarction(OR=4.13,95％CI:1.26-13.63)was a risk factor for cognitive impairment.Among old-aged patients with T2DM,drinking tea 1-2 times a week(OR=0.11,95％CI:0.01-0.58)and education at the junior college or undergraduate level and above(OR=0.19,95％CI:0.05-0.54)were protective factors for cognitive impairment.Stroke(OR=3.64,95％CI:1.55-8.39)and good sleep self-assessment(OR=2.75,95％CI:1.13-7.35)were risk factors for cognitive impairment.Conclusion:Cognitive impairment in middle-aged pa-tients with T2DM is related to work,education level and myocardial infarction,and cognitive impairment in old-aged patients with T2DM is related to lifestyle,education level and stroke.

Objective To explore the long-term efficacy of percutaneous pulmonary valve implantation(PPVI)and the durability of the domestic self-expanding Venus P valve.Methods A total of 8 patients with post-surgical right ventricular outflow tract(RVOT)dysfunction,who were admitted to hospital from October 2014 to July 2016 and deemed anatomically suitable for PPVI with self-expanding valve,were included prospectively.Clinical,imaging,procedural and follow-up data were analyzed.The survival rates,perioperative and long-term complication rates,long-term efficacy of PPVI,and long-term function of Venus P in 8 patients were evaluated.The immediate procedural results were evaluated by clinical implant success rate,which is defined as successful valve implantation with echocardiography-assessed pulmonary regurgitation＜moderate and peak trans-pulmonary pressure gradient＜40 mmHg.Results A total of 8 patients were included,with 7 females,aged 14 to 36 years.The initial diagnosis included post-surgical Tetralogy of Fallot(5 cases),post-surgical Trilogy of Fallot(1 case),post-surgical Quadricuspid pulmonary valve stenosis(1 case)and post-surgical Double-Outlet Right Ventricle(1 case).The indications of PPVI included RVOT-pulmonary obstruction and regurgitation(1 case)and isolated regurgitation(7 cases).Clinical implant success was achieved in all of the 8 patients with firmly fixed valve,and there were no such complications as valve detachment,displacement or stent fracture.All patients experienced significant symptom relief after the procedure.The right ventricular end-diastolic volume index(RVEDVi)measured by CMR 6 months after PPVI showed a significant decrease compared to preprocedural values[(89.99±13.85)ml/m2 vs.(144.93±11.28)ml/m2,P=0.001].Postoperative pulmonary regurgitation were significantly improved or disappeared in all patients,and there was no statistically significant difference in the average peak pressure gradient measured by echocardiogram between preoperative and the latest follow-up[(23.25±8.39)mmHg vs.(18.75±6.28)mmHg,P=0.210].Over an average follow-up period of(9.25±0.71)years,1 case of infective endocarditis occurred 5 years after PPVI.During the follow-up,no death,deterioration of heart failure,malignant arrhythmia or other serious complications were observed.All patients completed 8-year follow-up,and 3 completed 10-year follow-up.All patients were graded as NYHA functional class one at the latest follow-up.Conclusions PPVI using the domestically produced self-expanding Venus P is safe and feasible for the treatment of patients with post-surgical RVOT dysfunction and suitable anatomy.Our study confirms the long-term efficacy and durability of Venus P from multiple perspectives,and no severe stent fracture occurred without pre-stent implantation in the native RVOT.

Objective:To investigate the effect of nursing measures based on the Rockall scoring system combined with the SBAR communication model in patients with acute upper gastrointestinal bleeding.Methods:A convenience sampling method was used to select 140 patients with acute upper gastrointestinal bleeding admitted to the First Affiliated Hospital of Zhengzhou University from June 2022 to January 2024. The patients were divided into a control group and an observation group, with 70 cases in each. The control group received nursing measures based on the Rockall scoring system, while the observation group received nursing measures based on the Rockall scoring system combined with the SBAR communication model. Treatment compliance, bleeding status, length of hospital stay, psychological state, and self-management behavior scores were compared between the two groups.Results:After intervention, the treatment compliance of the observation group was significantly higher than that of the control group ( P<0.05) . The bleeding cessation time and hospital stay time were shorter in the observation group than in the control group ( P<0.05) . Eight weeks after intervention, the scores of Self-rating Anxiety Scale (SAS) and Self-rating Depression Scale (SDS) in the observation group were lower than those in the control group ( P<0.05) . Six months after intervention, the scores of all dimensions and the total score of self-management behaviors in the observation group were significantly higher than those in the control group ( P<0.05) . Conclusions:Nursing interventions based on the Rockall scoring system combined with the SBAR communication model can improve treatment compliance, reduce negative emotions, and enhance self-management ability in patients with acute upper gastrointestinal bleeding.

Pseudopleuronectes yokohamae is an important marine economic fish species in northern China and is vulnerable to various pathogens during the breeding process.To investigate the viru-lence of Edwardsiella tarda on Pseudopleuronectes yokohamae and elucidate the role of miRNAs in their interaction,we conducted pathological analyses on various tissues of Pseudopleuronectes yokohamae larvae pre-and post-infection with Edwardsiella tarda.Subsequently,Illumina high-throughput sequencing was employed to identify and functionally characterize differentially ex-pressed miRNAs in liver and kidney tissues.The results demonstrated that infection with Ed-wardsiella tarda led to ulceration,hemorrhaging,significant hepatomegaly,nephromegaly,and as-cites in the abdominal cavity.Histopathological examination revealed swollen hepatocytes with vac-uolization,minor blood cell infiltration,and enlarged renal corpuscles with signs of cellular lysis.miRNA sequencing analysis indicated that 24 miRNAs were significantly upregulated and 45 miR-NAs were significantly downregulated in the liver,while in the kidney,6 miRNAs were upregulat-ed and 58 were downregulated following infection.Functional enrichment analysis revealed signifi-cant enrichment of differentially expressed miRNAs in Toll and IMD signaling pathways,HIF-1 signaling pathway,Rap1 signaling pathway,MAPK signaling pathway,and Apelin signaling path-way.These findings suggest the involvement of these miRNAs in host metabolism,pathogen rec-ognition,and immune response in the interaction between Pseudopleuronectes yokohamae and Ed-wardsiella tarda.This research lays a foundation for elucidating the mechanisms underlying bacte-rial disease susceptibility and resistance in Pseudopleuronectes yokohamae.

Objective:To explore the feasibility and preliminary clinical experience of robot-assisted pelvic exenteration (PE) in the treatment of locally advanced (LARC) and recurrent (LRRC) rectal cancer.Method:A descriptive case series research method was adopted. Inclusion criteria included: (1) Age 18-80 years old; (2) Preoperative puncture biopsy performed through endoscopy, and a pathological diagnosis of rectal malignant tumor; (3) Preoperative imaging examinations confirming locally advanced (cT4b stage) or locally recurrent rectal cancer, with tumor location in the pelvic cavity; (4) Physical condition: ECOG score ≤1 point, and radical resection being feasible after assessment. The data for five patients with LARC or LRRC who underwent pelvic exenteration (PE) using the da Vinci robotic surgical system in the Department of Anorectal Surgery, the Second Affiliated Hospital of Naval Medical University (Shanghai Changzheng Hospital) from January, 2024 to January, 2025 were collected retrospectively. The mean age was (46.8±7.7) years, with 3 males and 2 females, who comprised 2 cases of LARC and 3 cases of LRRC. Two patients received preoperative radiotherapy, and 4 patients received preoperative chemotherapy. The average body mass index was (21.5±2.7) kg/m2. According to the American Society of Anesthesiologists (ASA) classification, 2 cases were grade II and 3 cases were grade III.Results:All patients with LARC or LRRC successfully underwent robot-assisted PE. The average operation time was (496.4±139.5) minutes; the average intraoperative blood loss was (72.0±29.5) ml; the average postoperative exhaust time was (50.0 ±13.6) hours; and the average postoperative defecation time was(64.2±15.3) hours. Mean early postoperative VAS pain scores was (3.6±1.5) points. Three patients underwent primary intestinal anastomosis, and 2 patients underwent colonic single-lumen ostomy. All 5 patients underwent urinary system reconstruction, among which 2 underwent ureterovesical reimplantation, 1 underwent percutaneous ureterostomy, 1 underwent ileal conduit replacement of bladder, and 1 underwent direct bladder suture. After surgery, except for 1 case of pelvic infection with effusion (Clavien-Dindo grade IIIa), there were no obvious postoperative complications. Postoperative pathological results showed that all patients achieved R0 resection, including 1 case of T4a stage and 4 cases of T4b stage (all involving urogenital organs or tissues), and 3 cases of N0 stage and 2 cases of N1 stage, with a maximum tumor diameter of (4.7±1.9) cm. The median postoperative follow-up time was 11 (range 7 to 17) months, and no patient experienced local recurrence.Conclusion:The above short-term preliminary results of robot-assisted PE in the treatment of LARC or LRRC within the pelvic cavity indicate that it is both safe and feasible.
