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: Congenital heart disease (CHD) is a leading cause of birth defect-related mortality. However, more recent CHD mortality data for China are lacking. Additionally, limited studies have evaluated sex, rural-urban, and region-specific disparities of CHD mortality in China. METHODS: We designed a population-based study using data from the Dataset of National Mortality Surveillance in China between 2008 and 2021. We calculated age-adjusted CHD mortality using the sixth census data of China in 2010 as the standard population. We assessed the temporal trends in CHD mortality by age, sex, area, and region from 2008 to 2021 using the joinpoint regression model. RESULTS: From 2008 to 2021, 33,534 deaths were attributed to CHD. The period witnessed a two-fold decrease in the age-adjusted CHD mortality from 1.61 to 0.76 per 100,000 persons (average annual percent change [AAPC] = -5.90%). Females tended to have lower age-adjusted CHD mortality than males, but with a similar decline rate from 2008 to 2021 (females: AAPC = -6.15%; males: AAPC = -5.84%). Similar AAPC values were observed among people living in urban (AAPC = -6.64%) and rural (AAPC = -6.12%) areas. Eastern regions experienced a more pronounced decrease in the age-adjusted CHD mortality (AAPC = -7.86%) than central (AAPC = -5.83%) and western regions (AAPC = -3.71%) between 2008 and 2021. Approximately half of the deaths (46.19%) due to CHD occurred during infancy. The CHD mortality rates in 2021 were lower than those in 2008 for people aged 0-39 years, with the largest decrease observed among children aged 1-4 years (AAPC = -8.26%), followed by infants (AAPC = -7.01%). CONCLUSIONS CHD mortality in China has dramatically decreased from 2008 to 2021. The slower decrease in CHD mortality in the central and western regions than in the eastern regions suggested that public health policymakers should pay more attention to health resources and health education for central and western regions.

OBJECTIVE To explore the possible mechanism of Qingchang Huashi Formula in the treatment of ulcerative colitis(UC).METHODS Fifty C57BL/6 male mice were randomly divided into a control(Ctrl)group,a model group,a low-dose Qingchang Huashi Formula group,a high-dose Qingchang Huashi Formula group,and a 5-aminosalicylic acid(5-ASA)group based on body weight.The UC model was established in mice by drinking 3%dextran sulfate sodium(DSS)for 6 d.On d7 and d8,DSS was withdrawn and ultrapure water was given daily.Ultrapure water or different drugs were administered orally throughout the experiment:Ctrl and model groups received 0.2 mL of ultrapure water,while the low-dose and high-dose Qingchang Huashi Formula groups re-ceived 6 and 12 g·kg-1,respectively,and the concentration of 5-ASA was 100 mg·kg-1.Body weight and fecal characteristics of the mice were recorded daily,and the experiment ended on d9.Serum was collected from mice for serum metabolomics and inflam-matory factor expression analysis.The colons of the mice were isolated and their lengths were measured,and the distal colon was ob-tained for pathological analysis.The livers and colons of the mice were isolated for subsequent total bile acid analysis.RESULTS Compared with the Ctrl group,the model group mice showed a significant decrease in body weight and colon length(P<0.000 1),a remarkable increase in disease activity index(P<0.000 1).The concentration of inflammatory factors IL-1β and TNF-α was signifi-cantly increased(P<0.000 1).High-dose and low-dose Qingchang Huashi Formula,as well as 5-ASA could significantly alleviate the loss of body weight,increased DAI,colon shortening,and disappearance of colon tissue morphology in mice.Through ELISA tes-ting,it was found the concentration of IL-1β and TNF-α was remarkably decreased after Qingchang Huashi Formula and 5-ASA treat-ment(P<0.01,P<0.000 1).Through LC-MS analysis of serum metabolites and KEGG enrichment analysis,we found that interven-tion with Qingchang Huashi Formula could significantly affect the primary bile acid synthesis,secondary bile acid synthesis and bile se-cretion.Using total bile acid reagent kit,we found that the total bile acid in the liver of colitis mice did not show significant changes when compared with the Ctrl group of mice,and the concentration of total bile acid in the serum was significantly reduced,the concen-tration of TBA in the colon was significantly increased(P<0.05).After intervention with the Qingchang Huashi Formula,the concen-tration of total bile acid in the serum of mice was significantly increased,while the concentration of total bile acid in the colon was re-duced(P<0.05).Compared with mice in Ctrl group,the levels of deoxycholic acid(DCA)and taurine deoxycholic acid(TDCA)in serum of colitis mice were significantly reduced(P<0.05).After intervention with Qingchang Huashi Formula,the levels of DCA,TD-CA and Ursodeoxycholic acid(UDCA)in serum of mice were restored(P<0.01).CONCLUSION Qingchang Huashi Formula can effectively relieve DSS-induced colitis in mice,reducing immune inflammatory response,reregulating the disorder of serum metabolism and enterohepatic circulation.

Objective To promote the objectification and intelligence of clinical TCM tongue diagnosis in ulcerative colitis(UC).Methods Daosheng DS01-B tongue and face diagnosis information collection system was used to prospectively collect tongue image pictures of patients with ulcerative colitis damp-heat in the large intestine syndrome(DCSR)and spleen deficiency dampness retention syndrome(PXSY),with totaling 1096 images.After UC tongue image segmentation,preprocessing,and data augmentation,a data set of UC tongue images was formed.Based on ResNet50,a UC tongue image classification model was constructed using feature fusion methods and attention modules.Results The UC tongue image classification model constructed had better classification performance,with an average F1 value of 85.09%,an AUC value of 0.83 for PXSY,and an AUC value of 0.81 for DCSR,both of which were higher than the VGG11 and ResNet50 models.Conclusion The constructed UC tongue image classification model can effectively identify DCSR and PXSY,providing a new approach to improve the accuracy and objectivity of UC differentiation and assisting in the intelligence of TCM tongue diagnosis.

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 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 analyze the changes of peripheral perfusion index (PPI) with late-onset sepsis (LOS) in very low birth weight infants during hospitalization.Methods:Very low birth weight infants admitted to the neonatal intensive care unit of Children′s Hospital of Fudan University from August 1, 2021 to August 31, 2022 were consecutively included.Infants with admission age ≥three days and unstable circulation, or positive blood culture within three days after birth were excluded.From the day of admission, the PPI values of the right hand and either foot of the infants were measured with Masimo SET Radical-7 everyday while whether LOS occurred during hospitalization was observed.The mean PPI curve of very and extremely low birth weight infants without LOS was plotted.For those with LOS confirmed by blood culture, the PPI change trajectory three days before and after the occurrence of LOS was drawn, and the change trend of PPI before the occurrence of LOS was analyzed by trend chi-square test.Non-parametric test was used to analyze the effect of LOS on pre- and post-ductal PPI values.Results:A total of 107 very low birth weight infants were included in the final analysis.Among them, there were 11 infants confirmed as LOS by blood culture, 37 infants diagnosed as clinical LOS, and 59 infants without LOS.Pre-and post-ductal PPI values of very low birth weight infants without LOS were 2.06±1.30 and 1.72±0.92, respectively; those with clinical LOS were 1.90±0.94 and 1.58±0.83, respectively; those with LOS confirmed by blood culture were 1.92±1.11 and 1.62±0.82, respectively.For infants with LOS confirmed by blood culture, the pre-and post-ductal PPI values showed a continuous downward trend during three days before the onset of disease, with the lowest PPI values on the first day before the diagnosis of blood culture.The downtrend of pre-ductal PPI was statistically significant ( χtrend2=5.57, P<0.05). Conclusion:The PPI value of very low birth weight infants show a downward trend when LOS occurs.It should be observed dynamically in clinical practice, which is helpful to suspect or identify LOS as early as possible.

Objective:To study the past 10 years' experiences of neonatal hydrocephalus in a single-center.Methods:From January 2010 to December 2019, clinical data of infants with hydrocephalus admitted to Neonatology Department of our hospital were retrospectively analyzed. The infants were assigned into different groups according to gestational age, different etiologies and treatments. Their clinical characteristics and outcomes were compared.Results:A total of 223 infants with hydrocephalus were included. 136 (61.0%) infants were in the preterm group and 87 (39.0%) in the full-term group. The incidence of post-intracranial hemorrhage (ICH) hydrocephalus in preterm infants was significantly higher than full-term infants ( P<0.001). According to the etiologies, 58 infants (26.0%) had congenital hydrocephalus (congenital group), 82 cases (36.8%) developed post-ICH hydrocephalus (ICH group), 48 cases (21.5%) had post-CNS-infection hydrocephalus (infection group) and 35 cases (15.7%) had post-ICH+CNS-infection hydrocephalus (ICH+infection group). The incidences of perinatal asphyxia, neonatal resuscitation and endotracheal intubation within 3 d after birth in the ICH group were significantly higher than the other groups ( P<0.05). Among the four groups, the infection group had the highest incidence of neonatal sepsis, the congenital group had the highest incidence of patent ductus arteriosus and the ICH group had the highest incidence of respiratory diseases (all P<0.05).137 cases (61.4%) received non-surgical therapy, 48 cases (21.5%) had temporary drainage, 37 cases (16.6%) with permanent shunt and 1 case (0.4%) intracranial hematoma removal. The congenital group and ICH group with permanent shunt showed significantly higher rate of improvement than temporary drainage group and non-surgical group ( P<0.001). Conclusions:The main etiologies of neonatal hydrocephalus are ICH and CNS infection. The incidence of post-ICH hydrocephalus in premature infants was quite high. Hydrocephalus of different etiologies have different comorbidities. Maternal and infant care during pregnancy and delivery, prevention of neonatal sepsis and ICH are crucial in the prevention of hydrocephalus. More studies are needed for better treatment.
