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.

Abstract On September 26, 2024, a municipal hospital in Jiaxing City reported a maternal case of Listeria monocytogenes infection. In order to clarify the source of infection, the Jiaxing Center for Disease Control and Prevention immediately conducted the epidemiological investigation, laboratory testing and related disposal work. The case presented with fever (37.9 ℃), gradually intensifying paroxysmal abdominal pain without obvious cause, and went to hospital on the day of onset. Due to fetal intrauterine distress, a male infant was delivered by cesarean section on the same day. The epidemiological investigation identified that the case usually consumed fruits, often store fruits such as watermelon and grapes in the refrigerator alongside raw meat, and the refrigerator had never been cleaned or disinfected, posing a risk of cross contamination. Laboratory tests on amniotic fluid sample from the pregnant woman, infant blood sample showed positive results for Listeria monocytogenes infection. One strain of Listeria monocytogenes was detected in a smear sample from the inner wall of the refrigerator, and all the strains were ST2 type. Consuming fruits contaminated with Listeria monocytogenes may be the main source of infection. Food safety education for pregnant women and their family members should be strengthened to reduce the risk of infection.

Objective To investigate and analyze the resources and application frequency of radiological diagnosis and treatment in Jinan City in 2023 and provide a basis for the rational application of radiological diagnosis and treatment resources and strengthening radiological health protection management. Methods The health administrative department issued a work plan. A general survey was conducted on radiological diagnosis and treatment institutions (excluding dental clinics) in Jinan City using a questionnaire. The survey covered the basic information of the radiological diagnosis and treatment institutions, the distribution of the radiological diagnosis and treatment equipment, the number of radiological workers, and the frequency of radiological diagnosis and treatment. Results There were 301 radiological diagnosis and treatment institutions in Jinan City, with 1603 sets of radiological diagnosis and treatment equipment and 5789 radiological workers. These institutions included 41 (13.62%) tertiary hospitals, 57 (18.94%) secondary hospitals, 110 (36.54%) primary hospitals, and 93 (30.90%) ungraded hospitals. Tertiary hospitals had the highest proportions of radiological diagnosis and treatment equipment and workers, accounting for 49.53% and 69.10% of the total, respectively. The frequencies of radiological diagnosis and treatment were 868.86 X-ray diagnostic imaging examinations per 1000 population, 5.07 radiotherapies per 1000 population, 14.19 interventional diagnostic and therapeutic procedures per 1000 population, 7.36 nuclear medical diagnostic procedures per 1000 population, and 0.56 nuclear medical therapeutic procedures per 1000 population. The frequency of CT diagnosis was the highest, reaching 407.76 procedures per 1000 population. Conclusion The radiological diagnosis and treatment resources and activities in Jinan City were mainly concentrated in tertiary hospitals, with unbalanced distribution among hospitals of different grades. It is necessary to apply various medical radiations correctly and reasonably and strengthen radiation protection to reduce the frequency of radiation and the collective effective dose.

Objective To retrospectively analyze the epidemiological trend of children with lower gastrointestinal bleeding in recent 10 years,and investigate the change of their disease burden,so as to provide a theoretical basis for the accurate prevention and control of children's lower gastrointestinal bleeding. Methods A total of 671 children with "lower gastrointestinal bleeding" who were diagnosed in our hospital from 2012 to 2021 were collected as research subjects. To analyze the microscopic examination rate and common etiology of lower gastrointestinal bleeding in children in the past 10 years,as well as the epidemiological characteristics of different age groups, different regions and different basic diseases; Calculate and compare the rate of disability life lost (YLD), early death life lost (YLL) and disability adjusted life year (DALY) of children with lower gastrointestinal bleeding within 10 years, and calculate the annual change percentage (AAPC) to analyze the change trend of disease burden. Results The microscopic examination rate of children with lower gastrointestinal bleeding showed a trend of increasing in the past 10 years (P<0.001). Among them, the most common causes are Crohn's disease, ulcerative colitis and chronic colitis. The proportion of children with lower gastrointestinal bleeding was higher in boys, >18 years old, hypertension and gastroenteritis. The DALY rate, YLL rate and YLD rate caused by lower gastrointestinal bleeding in the past 10 years showed an upward trend (P<0.05). Conclusion The microscopic examination rate of lower gastrointestinal bleeding in children was graduallyincreasing,and the prevalence rate of basic diseases such as boys,hypertension and gastroenteritis was increasing;in addition,the disease burden caused by children's lower gastrointestinal bleeding was also increasing year by year and should be protected.

Objective:To investigate the value of systemic inflammatory response syndrome (SIRS), pediatric sequential organ failure assessment (pSOFA) and pediatric critical illness score (PCIS) in predicting mortality of pediatric sepsis in pediatric intensive care units (PICU) from Southwest China.Methods:This was a prospective multicenter observational study. A total of 447 children with sepsis admitted to 12 PICU in Southwest China from April 2022 to March 2023 were enrolled. Based on the prognosis, the patients were divided into survival group and non-survival group. The physiological parameters of SIRS, pSOFA and PCIS were recorded and scored within 24 h after PICU admission. The general clinical data and some laboratory results were recorded. The area under the curve (AUC) of the receiver operating characteristic curve was used to compare the predictive value of SIRS, pSOFA and PCIS in mortality of pediatric sepsis.Results:Amongst 447 children with sepsis, 260 patients were male and 187 patients were female, aged 2.5 (0.8, 7.0) years, 405 patients were in the survival group and 42 patients were in the non-survival group. 418 patients (93.5%) met the criteria of SIRS, and 440 patients (98.4%) met the criteria of pSOFA≥2. There was no significant difference in the number of items meeting the SIRS criteria between the survival group and the non-survival group (3(2, 4) vs. 3(3, 4) points, Z=1.30, P=0.192). The pSOFA score of the non-survival group was significantly higher than that of the survival group (9(6, 12) vs. 4(3, 7) points, Z=6.56, P<0.001), and the PCIS score was significantly lower than that of the survival group (72(68, 81) vs. 82(76, 88) points, Z=5.90, P<0.001). The predictive value of pSOFA (AUC=0.82) and PCIS (AUC=0.78) for sepsis mortality was significantly higher than that of SIRS (AUC=0.56) ( Z=6.59, 4.23, both P<0.001). There was no significant difference between pSOFA and PCIS ( Z=1.35, P=0.176). Platelet count, procalcitonin, lactic acid, albumin, creatinine, total bilirubin, activated partial thromboplastin time, prothrombin time and international normalized ratio were all able to predict mortality of sepsis to a certain degree (AUC=0.64, 0.68, 0.80, 0.64, 0.68, 0.60, 0.77, 0.75, 0.76, all P<0.05). Conclusion:Compared with SIRS, both pSOFA and PCIS had better predictive value in the mortality of pediatric sepsis in PICU.

Objective To investigate the relationships of serum angiopoietin-like protein 4 (ANGPTL4) and fibroblast growth factor-23 (FGF-23) levels with the severity and prognosis of patients with diabetic nephropathy. Methods A total of 120 patients (diabetic nephropathy group) with diabetic nephropathy were selected from July 2018 to July 2020 and divided into mild group (n=62) and severe group (n=58) according to the staging criteria of diabetic nephropathy; based on the prognosis within 3 years, they were also divided into good prognosis group (n=94) and poor prognosis group (n=26). Additionally, 102 diabetic patients were enrolled as diabetic group, and 81 healthy volunteers were selected as control group. The serum levels of ANGPTL4 and FGF-23 in diabetic nephropathy patients were detected by enzyme-linked immunosorbent assay (ELISA). Logistic regression analysis was used to analyze the influencing factors of prognosis, and receiver operating characteristic (ROC) curves were drawn to analyze the values of ANGPTL4, FGF-23 and their combination in assessing the severity and prognosis of diabetic nephropathy. Results The levels of ANGPTL4 and FGF-23 in the diabetic nephropathy group and simple diabetic group were significantly higher than those in the control group (P < 0.05); compared with the simple diabetic group, the levels of ANGPTL4 and FGF-23 in the diabetic nephropathy group were significantly increased (P < 0.05); the levels of ANGPTL4 and FGF-23 in the severe group were significantly higher than those in the mild group (P < 0.05); the ROC curve analysis revealed that the areas under the curve (AUCs) for assessing disease severity of ANGPTL4, FGF-23 and their combination were 0.748, 0.781 and 0.858 respectively, and the combined diagnosis was significantly better than FGF-23 (Z=2.149, P=0.032) and ANGPTL4 (Z=2.886, P=0.004) alone; the levels of ANGPTL4 and FGF-23 in the good prognosis group were significantly lower than those in the poor prognosis group (P < 0.05); significant differences were observed in diabetes duration, blood urea nitrogen (BUN), serum creatinine (Scr), fasting blood glucose (FBG), glycated hemoglobin (HbA1C), hypertension, ANGPTL4 and FGF-23 levels between diabetic nephropathy patients with different prognoses (P < 0.05); the Scr, ANGPTL4 and FGF-23 levels were all risk factors affecting the prognosis of diabetic nephropathy (P < 0.05); the ROC curve analysis for prognosis assessment showed that the AUCs of ANGPTL4, FGF-23 and their combination were 0.774, 0.795 and 0.874 respectively; the combined diagnosis was significantly better than FGF-23 (Z=2.385, P=0.171) and ANGPTL4 (Z=2.317, P=0.021) alone. Conclusion The serum levels of ANGPTL4 and FGF-23 are significantly increased in diabetic nephropathy patients, and they have certain reference value for the clinical diagnosis and prognosis assessment of diabetic nephropathy patients.

Objective: To perform an epidemiological survey of the first case with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in Pinghu City of Jiaxing City, Zhejiang Province on March 13, 2022, so as to provide insights into the management of coronavirus disease (COVID-19) epidemics. Methods: According to the requirements of the Protocol on Prevention and Control of COVID-19 (8th Edition), epidemiological investigations were performed among 39 cases with SARS-CoV-2 infections in Pinghu City from March 13 to 20, 2022. Cases' demographics, clinical symptoms, history of immunization and exposure were collected, and close contacts were identified. Pharyngeal swabs were sampled from infected cases for detection of SARS-CoV-2 nucleic acid and whole-genome sequencing, and the source of infection and transmission route were investigated. Results: The index case for this COVID-19 epidemic was an imported case from Shanghai Municipality, who infected 6 persons via aerosol transmission when playing in the badminton venue of Pinghu National Fitness Center on March 9; subsequently, one of these infected cases infected another 18 persons when playing in the badminton venue of Jiadian Village Resident's Fitness Center in Zhapu Township on March 12. Sixteen confirmed cases were reported, and all cases were mild; another 23 asymptomatic cases were diagnosed, with no death reported. This epidemic occurred from March 11 to 20, with 3 generations of spread and a median incubation period of 3 days. The SARS-CoV-2 infected cases had a median age of 33.5 (interquartile range, 12.0) years and included 36 cases with a history of COVID-19 vaccination. There were 16 cases with fever, cough, runny nose and sore throat, and 13 cases with imaging features of pneumonia. The effective reproductive number (Rt) of the COVID-19 epidemic was 7.73 at early stage, and was less than 1 since March 21. Whole-genome sequencing identified Omicron BA.2 variant among 33 cases, which had high homology with the index cases. Conclusion This epidemic was a cluster of COVID-19 caused by imported Omicron BA.2 variant infection from Shanghai Municipality, and the COVID-19 transmission was mainly caused by indoor aerosols.

ObjectiveTo explore the effect of exposure to atmospheric particulate matters on the outpatient visits of respiratory disorders in Jiaxing City，Zhejiang Province. MethodsDaily air pollutant monitoring data，meteorological data and outpatient visits of respiratory disorders in Jiaxing City from 2019 to 2021 were collected．A generalized additive model was applied to evaluate the effect and laggeel effect of the concentrations of atmospheric particulates for outpatient visits of respiratory disorders after adjusting for secular trend， day-of-the-week effect， holiday effect， and meteorological variables. ResultsThe daily average concentrations of PM_2.5， PM₁₀， O₃ and NO₂ exceeded the standard， and the proportion of days exceeding the standard was 3.4%， 1.3%， 11.0% and 0.8%， respectively. Every 10 μg·m^-3 increase in PM_2.5 concentration showed the strongest effects on the daily outpatient visits of respiratory disorders， adult and childhood respiratory disorders all on lag07 with ER（95%CI） being 2.29%（1.35%‒3.24%）， 2.31% （1.39%‒3.23%） and 2.65 % （1.36%‒3.96%）， respectively. The maximum ER of outpatient visits for respiratory disorders in children was higher than that in adults. Every 10 μg·m^-3 increase in PM₁₀ concentration showed the strongest effects on the daily outpatient visits of respiratory disorders on lag07， adult respiratory disorders on lag06 and childhood respiratory disorders on lag07 with ER（95%CI） being 1.42% （0.87%‒1.96%）， 1.49%（0.99%‒1.99%） and 1.61% （0.87%‒2.36%）， respectively. The results of double-pollutant model showed that the effect of atmospheric particulate reduced after O₃ was introduced into the model. ConclusionThere are a short-term effect and a laggeel effect of atmospheric particulate on the outpatient visits of respiratory disorders. It is necessary to strengthen the health protection of the respiratory system of the population， especially the children.

Objective: To investigate the delay in identification of pulmonary tuberculosis and influencing factors among children and adolescents in Jiaxing City, Zhejiang Province from 2013 to 2022, so as to provide the reference for targeted prevention and control measures. Methods: The information of pulmonary tuberculosis patients in Jiaxing City from 2013 to 2022 were captured from the Tuberculosis Information Management System of Chinese Disease Control and Prevention Information System, including demographics, diagnosis, treatment and etiological results. The delay in identification of pulmonary tuberculosis was analyzed among children and adolescents, and the factors affecting the delay in identification of pulmonary tuberculosis were identified using a multivariable logistic regression model. Results: A total of 2 407 pulmonary tuberculosis cases were reported among children and adolescents in Jiaxing City from 2013 to 2022, including 1 522 males (63.23%). The median age was 21.00 (interquartile range, 4.00) years. There were 410 students (17.03%), and 1 856 cases with non-local household registration (77.11%). There were 596 cases with delay in identification of tuberculosis (24.76%), 895 cases with delay in healthcare-seeking (37.18%) and 128 cases with delay in definitive diagnosis (5.32%). Multivariable logistic regression analysis that children and adolescents who occurred symptoms in the first quarter (OR=1.684, 95%CI: 1.261-2.249), were diagnosed first in county-level medical institutions (OR=3.800, 95%CI: 2.898-4.983) and had positive results of etiological testing (OR=1.534, 95%CI: 1.255-1.874) were more likely to delay in identification of pulmonary tuberculosis. Conclusions The delay in identification of pulmonary tuberculosis is associated with the time of symptom onset, the level of medical institution making first diagnosis, and the results of etiological testing. It is suggested to reinforce the publicity of pulmonary tuberculosis prevention and control, expand the coverage of screening programs and improve the diagnosis capability of medical institutions.
