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 analyze the risk factors of prognosis in patients with intracranial solitary fibrous tumor/hemangiopericytoma (SFT/HPC).Methods:The clinical data of 74 intracranial SFT/HPC patients underwent surgical treatment from January 2017 to January 2024 in Luhe Hospital, Capital Medical University and Sanbo Brain Hospital, Capital Medical University were retrospectively analyzed. The patients were followed up the prognosis (including recurrence, death and extracranial metastasis). Kaplan-Meier and log-rank tests were used to analyze the risk factors of prognosis in patients with intracranial SFT/HPC, and multivariate Cox analysis was used to analyze the independent risk factors of prognosis in patients with intracranial SFT/HPC.Results:Seventy-four patients with intracranial SFT/HPC were followed up for 3 to 80 months, averaging 52.5 months. Among them, there were 17 cases of recurrence, 6 cases of extracranial metastasis, and 12 cases of death. In patients with intracranial SFT/HPC, the results of the log-rank univariate analysis showed that the tumor location, resection extent, WHO pathological grade, and adjuvant radiotherapy were risk factors of recurrence ( P<0.01); the tumor location, WHO pathological grade and extracranial metastasis were risk factors of death ( P<0.05 or <0.01); and the age, WHO pathological grade and Ki67 were risk factors of extracranial metastasis ( P<0.05 or <0.01). In patients with intracranial SFT/HPC, multivariate Cox regression analysis result showed that the subtotal resection and non-postoperative radiation therapy were independent risk factors of recurrence ( HR = 0.377 and 0.315, 95% CI 0.148 to 0.932 and 0.164 to 2.221, P<0.01 and <0.05); the WHO pathological grade Ⅲ and extracranial metastasis were independent risk factors of death ( HR = 3.657 and 1.657, 95% CI 0.964 to 7.147 and 0.964 to 2.848, P<0.01); the WHO pathological grade Ⅲ was an independent risk factor of extracranial metastasis ( HR = 1.657, 95% CI 0.964 to 2.848, P<0.01). Conclusions:Patients with intracranial SFT/HPC who undergo subtotal resection and non-postoperative radiation therapy are more prone to recurrence, WHO pathological grade Ⅲ patients are more likely to develop extracranial metastases, and extracranial metastases patients have shorter survival. For intracranial SFT/HPC patients with pathologically high-grade, SFT/HPC, it is necessary to increase the frequency of follow-ups and be alert for extracranial metastasis.

Objective:To understand the information needs and experiences of primary caregivers of patients in the emergency resuscitation room of the emergency department, and to provide a reference for clinical staff to meet caregivers′ information needs as well as to develop targeted and effective health information support for doctors and patients.Methods:A descriptive phenomenological research method was used to conduct semi-structured interviews with primary caregivers of 14 patients in the emergency resuscitation room of the First Affiliated Hospital of Nanjing Medical University from November 2023 to February 2024 through purposive sampling, and the Colaizzi 7-step analysis method was applied to summarize and analyze the interview data and refine the themes.Results:Totally 14 respondents aged 28-66, including 6 males and 8 females. Four themes were refined including diverse information needs, information access dilemma, integration of doctor-patient information for joint decision-making and communication, and desire for information and emotional support.Conclusions:The information needs of primary caregivers of patients in the emergency department were diverse, and caregivers were eager to seek patient-related information and crave emotional support and communication when faced with the onset of a patient's illness. Healthcare professionals should strengthen the assistance of caregivers′ information needs to improve the experience of patients and caregivers in medical consultation services and realize the sustainable development of the doctor-patient relationship.

Objective To explore the difference in clinical efficacy of sacubitril valsartan(SV)and enalapril in the treatment of elderly patients with chronic heart failure with reduced ejection frac-tion(HFrEF).Methods A total of 126 elderly patients with chronic HFrEF admitted in our de-partment between January 2020 and January 2023 were prospectively recruited and randomly di-vided into control group(enalapril treatment,63 cases)and observation group(SV treatment,63 cases).After 3 months of treatment,the improvement rate of NYHA cardiac function grade,and changes in cardiac function indicators[6-minute walking distance(6MWD),NT-proBNP,LVEDD,LVEF],and echocardiographic indicators[left ventricular myocardial work(Tei)index,stroke volume,cardiac output(CO)]before and after treatment,adverse reactions during treat-ment and prognosis were compared between the two groups.Results The improvement rate of NYHA grade was significantly higher in the observation group than the control group(80.95％vs 65.08％,P＜0.05).The results of 6MWD,LVEF,stroke volume and CO were obviously higher in both groups after treatment than before treatment(P＜0.05).The results of 6MWD,LVEF,stroke volume and CO were notably higher in the observation group than the control group(P＜0.01).The SBP,DBP,NT-proBNP,heart rate,LVEDD and LV Tei index were decreased after treatment in both groups,and those in the observation group were even lower than those in the control group(P＜0.05,P＜0.01).As of April 2024,the readmission rates due to HF was re-markably lower in the observation group than the control group(7.94％vs 20.63％,P＜0.05),but no statistical difference was seen in the mortality or the incidence of adverse reactions be-tween them(P＞0.05).Conclusion SV is superior to enalapril in improving the efficacy,cardiac function and cardiac load of elderly HFrEF patients,with advantages of reducing the incidence of readmission but not increasing adverse reactions.

Objective To explore the mechanism of Chaipo Decoction in intervening lipopolysaccharide(LPS)-induced acute lung injury(ALI)based on network pharmacology and experimental verification.Methods TCMSP database was used to screen the active components and targets of Chaipo Decoction.ALI disease targets were retrieved through GeneCards and OMIM databases,the intersection genes of drug and disease were obtained.They were imported into STRING platform and Cytoscape 3.9.1 software to construct protein interaction network and drug-active components-target network,core components and targets were screened,and GO and KEGG pathway enrichment analysis was performed on them.AutoDock 1.5.6 and PyMOL software were used to verify the molecular docking between the main active components and core targets.The ALI model of mice was induced by LPS,and was intervened by Chaipo Decoction.The pathological changes of lung tissue in mice were observed by HE staining.The contents of IL-6,IL-10 and TNF-α in serum of mice were detected by ELISA.Western blot was used to verify the expressions of target proteins in lung tissue.Results Totally 214 active components of Chaipo Decoction,such as norwogonin,baicalein,quercetin and ursolic acid were screened,with 1 101 targets and 271 potential targets for intervention in ALI,mainly SRC,STAT3,AKT1,EGFR,GRB2,PIK3CA,etc.It mainly affected PI3K/Akt signaling pathway,MAPK signaling pathway,apoptosis,Ras signaling pathway,etc.Molecular docking showed that the main active components of Chaipo Decoction had strong binding ability with core targets SRC,STAT3,AKT1,EGFR and GRB2.The results of animal experiments showed that Chaipo Decoction could alleviate the lung lesions in ALI mice,decrease the contents of IL-6 and TNF-α in serum,increase the content of IL-10,and significantly decreased the expressions of EGFR,PI3K,AKT and NF-κB p65 protein in lung tissue.Conclusion Chaipo Decoction can exert anti-ALI effect through multiple pathways and multiple targets,and its mechanism may be related to the inhibition of EGFR/PI3K/Akt signaling pathway.

An assay was established for detection of toxigenic Clostridioides difficile by combining microfluidic chip analysis with immunochromatography,and its performance was evaluated and compared with those of the Xpert C.difficile/Epi and VIDAS CD AB tests.Primer pairs were designed according to the tcdB and tpi genes in C.difficile.The specificity,limit of detection,reproducibility,and stability were evaluated.A total of 215 stool samples from patients with diarrhea were collected and tested in parallel with the Xpert C.difficile/Epi,VIDAS CDAB,and our assay.C.difficile was isolated from samples,and the tcdB gene was identified when discrepant results were obtained from the three above assays.Our assay showed no cross-reaction with other diarrhea-associated pathogens.Its reproducibility was 100％in testing of two standard plasmids containing tcdB and tpi genes at two concentrations(105 and 102 copies/μL).Two standard plasmids were detected after the PCR and immunochromatography reagents had been stored for 3,6,9,and 12 months,and all the results were posi-tive.The limit of detection was 10 copies/μL for toxigenic C.difficile.Testing of 33 samples positive for C.difficile with our assay(33/215,15.3％)yielded findings statistically coherent with those of the Xpert C.difficile/Epi test(kappa value=0.965).The sensitivity,specificity,positive predictive value,and negative predictive value of our assay,with respect to Xpert C.difficile/Epi as the standard,were 94.3％,100.0％,100.0％,and 98.9％;these values were significantly higher than those of VIDAS CDAB(60.0％,98.9％,91.3％,and 92.7％)(Kappa=0.714,OR=157.50,95％CI:62.03-847.28,P=0.013).In conclusion,our newly developed assay is specific,stable,and reproducible,and may be used for rapid and accu-rate detection of toxigenic C.difficile.The assay could be used for C.difficile infection screening in outpatient and emergen-cy,community medical service center,and epidemiological settings.

Objective To evaluate the efficacy and safety of a novel intravascular lithotripsy(IVL)balloon—Vesscrack shockwave balloon—for vascular preparation before stent implantation in patients with severe coronary artery calcification(CAC).Methods This was a prospective,single-arm,multicenter study conducted in China from June 2022 to October 2022.Patients with severe CAC were treated with the Vesscrack shockwave balloon for lesion preparation,followed by drug-eluting stent(DES)implantation.Of these,33 patients underwent optical coherence tomography(OCT).The primary endpoint was procedural success,defined as successful stent implantation with residual stenosis≤30％and the absence of in-hospital major adverse events,including cardiac death,target vessel-related myocardial infarction,or target lesion revascularization.Results A total of 170 patients[mean age:(65.9±7.9)years,116 males]were enrolled.After treatment with IVL and DES,the minimum lumen diameter increased significantly compared to baseline[(2.34±0.40)mm vs.(0.95±0.33)mm,P＜0.001],the degree of stenosis was significantly reduced[(13.24±6.60)％vs.(65.18±10.59)％,P＜0.001].Procedural success was achieved in 100％of cases,and device success was 98.8％.The 30-day patient-related cardiovascular clinical composite endpoint(POCE)rate was 0.0,with no target lesion failure,no confirmed or potential thrombotic events were observed.The shockwave energy generator demonstrated excellent stability and ease of use.Among the 33 patients assessed with OCT,after IVL intervention,the maximum calcified area of the lumen[(3.51±1.51)mm2 vs.(2.85±1.80)mm2,P＜0.001],and the minimum lumen area within the target lesion[(3.08±1.04)mm2 vs.(2.02±0.75)mm2,P＜0.001],and after DES intervention,the luminal area of the largest calcified site[(6.59±1.64)mm2 vs.(2.85±1.80)mm2,P＜0.001]and the minimum luminal area within the target lesion[(6.19±1.45)mm2 vs.(2.02±0.75)mm2,P＜0.001]were significantly increased,and the differences were statistically significant.Conclusions The Vesscrack shockwave balloon is effective and safe for vascular preparation in patients with severe CAC prior to stent implantation.It achieves significant calcified plaque modification,high procedural success rates,and minimal complications.
