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.

PURPOSE: To analyze risk factors for severe trauma and establish a nomogram for early risk prediction, to improve the early identification of severe trauma. METHODS: This study was conducted on the patients treated in 81 trauma treatment institutions in Gansu province from 2020 to 2022. Patients were grouped by year, with 5364 patients from 2020 to 2021 as the training set and 1094 newly admitted patients in 2020 as the external validation set. Based on the injury severity score (ISS), patients in the training set were classified into 2 subgroups of the severe trauma group (n = 478, ISS scores ≥25) and the non-severe trauma group (n = 4886, ISS scores <25). Univariate and binary logistic regression analyses were employed to identify independent risk factors for severe trauma. Subsequently, a predictive model was developed using the R software environment. Furthermore, the model was subjected to internal and external validation via the Hosmer-Lemeshow test and receiver operating characteristic curve analysis. RESULTS: In total, 6458 trauma patients were included in this study. Initially, this study identified several independent risk factors for severe trauma, including multiple traumatic injuries (polytrauma), external hemorrhage, elevated shock index, elevated respiratory rate, decreased peripheral oxygen saturation, and decreased Glasgow coma scale score (all p < 0.05). For internal validation, the area under the receiver operating characteristic curve was 0.914, with the sensitivity and specificity of 88.4% and 87.6%, respectively; while for external validation, the area under the receiver operating characteristic curve was 0.936, with the sensitivity and specificity of 84.6% and 93.7%, respectively. In addition, a good model fitting was observed through the Hosmer-Lemeshow test and calibration curve analysis (p > 0.05). CONCLUSION This study establishes a nomogram for early risk prediction of severe trauma, which is suitable for primary healthcare institutions in underdeveloped western China. It facilitates early triage and quantitative assessment of trauma severity by clinicians prior to clinical interventions.

Acute lateral ankle sprain (ALAS) is one of the most common sport injuries, with high incidence, recurrence and disability rates. Currently, exercise rehabilitation-based non-surgical treatment is the primary management approach for ALAS. However, there remain improper practices such as excessive immobilization or uncontrolled activity, which contribute to recurrent sprains and chronic ankle instability, significantly impairing patients′ athletic function and quality of life. To standardize the non-surgical management of ALAS, improve the cure rates, and reduce the recurrence and disability rates, Chinese Sports Rehabilitation Medicine Training Project of Chinese Medical Association, Foot and Ankle Basics and Orthopedics Group, Orthopedic Branch of Chinese Medical Doctor Association, and Sports Medicine Branch of Jiangsu Medical Association organized relevant experts to formulate Expert consensus on non-surgical treatment for acute lateral ankle sprain ( version 2025), following the principles of scientific vigor, practicality, and innovation. Thirteen recommendations were proposed for standardized treatment protocols across different healing phases, aiming to provide references for standard management of ALAS and improve the therapeutic outcomes.

Objective:To evaluate the application potential of the bimodal ultrasound/near-infrared (NIR) composite nanoscale probe Arg-Gly-Asp (RGD)/Ag 2Te/perfluoropentane (PFP) @ mesoporous silica nanoparticles (MSN) in the diagnosis and treatment of microvascular diseases. Methods:Nanoprobes loaded with RGD, PFP and Ag 2Te were prepared by ultrasound sonication and carbodiimide method. The characterization of the nanoprobes was determined. The imaging performance, photothermal response, and target-seeking ability of the nanoprobes under NIR irradiation were verified. The biosafety of the nanoprobes was examined, and the thrombolytic ability of the nanoprobes was evaluated. The mice were observed to visualize microvessels of the abdominal wall under the NIR-Ⅱ imaging, and the microvascular visualization ability of the nanoprobes was evaluated. Results:The particle size of nanoprobes was (205.3±2.9) nm and the potential was (2.05±0.58) mV. The coupling rate of the RGD was (82.27±0.36)%, the encapsulation rate of the quantum dots was (80.80±3.26)%, and the photostability of the quantum dots was good. The fluorescence intensity was enhanced with the increase of the mass concentration of RGD/Ag 2Te/PFP@MSN, and the warming effect was more obvious. After ultrasound and NIR irradiation, the thrombolysis rate was significantly increased. RGD/Ag 2Te/PFP@MSN successfully realized NIR-Ⅱ fluorescence imaging of mice microvessels. The cytotoxicity assay and hemolysis assay showed that the probe had a good biosafety. Conclusion:The RGD/Ag 2Te/PFP@MSN nanoprobe is a potential strategy for targeted therapy of thrombotic diseases, combining dual-modality therapy of ultrasound and NIR to offer new possibilities for non-invasive and visual diagnosis and treatment of microvascular embolism.

Objective:To investigate the association of immediate preoperative hyperglycemia (IPH) with postoperative pulmonary complications (PPCs) in patients with diabetes mellitus following video-assisted thoracoscopic partial lung surgery (VATPLS).Methods:This was a retrospective cohort study. The patients with diabetes mellitus who underwent elective VATPLS at the First Affiliated Hospital of Nanjing Medical University from January, 2018 to July, 2020 were recruited. Based on immediate preoperative blood glucose levels (fasting blood glucose within 2 h before surgery), the patients were divided into hyperglycemia group (IPH group, blood glucose concentration ≥7.8 mmol/L) and non-hyperglycemia group (non-IPH group, blood glucose concentration <7.8 mmol/L). The association of IPH with the occurrence of PPCs was analyzed using the prospensity score matching.Results:Data from 438 diabetic patients who underwent VATPLS were ultimately collected in this study. Compared with non-IPH group, the incidence of PPCs was significantly increased in IPH group ( P<0.001). After propensity score matching, 128 cases were assigned to both IPH group and non-IPH group, the risk of PPCs in IPH group was 1.33 times of that in non-IPH group (relative risk 1.33, 95% confidence interval 1.02-1.73, P=0.031). There were no interactions between age factors/preoperative glycated hemoglobin and IPH. Conclusions:IPH (fasting blood glucose within 2 h before surgery ≥7.8 mmol/L) is associated with the occurrence of PPCs to some degree in patients with diabetes mellitus undergoing VATPLS.

OBJECTIVE: To evaluate the efficacy and safety of Shexiang Tongxin Dropping Pill (STDP) in treating stable angina patients with phlegm-heat and blood-stasis syndrome by exercise duration and metabolic equivalents. METHODS: This multicenter, randomized, double-blind, placebo-controlled clinical trial enrolled stable angina patients with phlegm-heat and blood-stasis syndrome from 22 hospitals. They were randomized 1:1 to STDP (35 mg/pill, 6 pills per day) or placebo for 56 days. The primary outcome was the exercise duration and metabolic equivalents (METs) assessed by the standard Bruce exercise treadmill test after 56 days of treatment. The secondary outcomes included the total angina symptom score, Chinese medicine (CM) symptom scores, Seattle Angina Questionnaire (SAQ) scores, changes in ST-T on electrocardiogram and adverse events (AEs). RESULTS: This trial enrolled 309 patients, including 155 and 154 in the STDP and placebo groups, respectively. STDP significantly prolonged exercise duration with an increase of 51.0 s, compared to a decrease of 12.0 s with placebo (change rate: -11.1% vs. 3.2%, P<0.01). The increase in METs was significantly greater in the STDP group than in the placebo group (change: -0.4 vs. 0.0, change rate: -5.0% vs. 0.0%, P<0.01). The improvement of total angina symptom scores (25.0% vs. 0.0%), CM symptom scores (38.7% vs. 11.8%), reduction of nitroglycerin consumption (100.0% vs. 11.3%), and all domains of SAQ, were significantly greater with STDP than placebo (all P<0.01). The changes in Q-T intervals at 28 and 56 days from baseline were similar between the two groups (both P>0.05). Twenty-five participants (16.3%) with STDP and 16 (10.5%) with placebo experienced AEs (P=0.131), with no serious AEs observed. CONCLUSION STDP could improve exercise tolerance in patients with stable angina and phlegm-heat and blood stasis syndrome, with a favorable safety profile. (Registration No. ChiCTR-IPR-15006020).
