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 gain insights into the biological characteristics of different populations of Culex tritaeniorhynchus within and around the Yellow Sea wetland from the perspective of the occurrence of resistance, we investigated the levels of resistance to deltamethrin and kdr gene mutation in the wetland and its peripheral areas. Methods Specimens were collected from Cx. tritaeniorhynchus populations at two monitoring sites in the Rare Bird National Nature Reserve and Tiaozi Ni Wetland Scenic Area, and also from two populations in Yancheng City and the Liuhe District of Nanjing, and the resistance of these mosquitoes to deltamethrin was determined using the CDC biotest bottle method. For each concentration of deltamethrin assessed, a random subset of exposed specimens was selected for amplification of the kdr gene fragment, followed by Sanger sequencing to identify and analyze resistance-associated mutations. Results The LC50 levels of deltamethrin among mosquitoes from the four populations in Luhe, Yancheng, the Rare Bird National Nature Reserve and the Tiaozi Ni Wetland Scenic Area were 2.048 5, 7.798 2, 3.473 3, and 17.695 5 mg/mL, respectively, with corresponding concentrations of deltamethrin ranging from 0.005 to 5.000,0.050 to 50.000,0.050 to 25.000 and 0.050 to 50.000 mg/mL, respectively. Furthermore, the ranges of the KT50 values were 11.76-107.43, 67.05-216.30,29.77-107.43 and 28.40-329.51 min; the 1-h knockdown rates were 34.58%-99.15%, 9.52%-43.80%, 55.09%-73.01%, and 10.09%-68.07%; and the 24-h mortality rates were 12.15%-67.52%,9.52%-79.56%,13.17%-82.21%, and 11.01%-78.99%, respectively. With respect to kdr gene mutation, we assayed a total of 63,70,59, and 57 mosquitoes for the four populations, for which we detected L1014F mutation frequencies of 14.29%, 35.00%, 20.34%, and 31.58%, respectively, with a majority of these mutations being heterozygous for resistance. In addition, five adult mosquitoes were identified has having synonymous mutations at site 1011[i. e. , AAT(asparagine)mutation to AAC(asparagine)]. Conclusions Our findings revealed the clear resistance of Cx. tritaeniorhynchus to deltamethrin in the Yancheng region of the Yellow Sea wetland, and the resistance phenotype and kdr frequency of Cx. tritaeniorhynchus in the wetland environment were comparable to those of Cx. tritaeniorhynchus in the wetland environment, thereby indicating that the resistance of different populations of Cx. tritaeniorhynchus was homogeneous under the pressure of different insecticide selection within and around the wetland. However, the underlying mechanisms need to be further studied.

Breast milk is the optimal natural food for newborns. However， some newborns cannot receive maternal breast milk due to reasons such as mother-infant separation or insufficient lactation. The establishment of human milk banks （HMB） can effectively address these issues， thereby increasing the breastfeeding rate among hospitalized newborns and improving their quality of survival. However， HMB in China is still in the development and improvement stage. Its implementation involves a series of ethical issues， such as informed consent， privacy protection， economic incentives， quality and safety， and fair resource distribution， which hinder HMB’s widespread promotion. Therefore， discussing the ethical dilemmas faced by the widespread establishment of HMB in China’s hospitals and analyzing coping strategies are crucial for improving the breastfeeding rate of newborns. This paper deeply analyzed and sorted out the ethical issues and challenges currently faced by HMB in China， and proposed corresponding strategies， including “ensuring informed consent and voluntary participation of both donors and recipients，” “protecting the privacy of donors and recipients，” “establishing an ethics-based moral incentive and social support system，” “strictly controlling quality and safety issues”， and “developing fair and rational policies，” aiming to provide a reference solution for addressing ethical concerns in the establishment and operation of HMB.

Objective To investigate the effect and mechanism of hypoxia inducible factor-1 α/aquaporin-4(HIF-1α/AQP4)pathway in high altitude cerebral edema(HACE)after blood-brain barrier injury in rats.Methods Adult male SD rats(n=40)were randomly divided into two groups:control group(Ctrl,n=20)and high altitude cerebral edema group(HACE,n=20).The rats in the control group were reared in Xining(altitude 2261 m)for 4 days,and the rats in HACE group were reared in low-pressure simulation chamber(altitude 5000 m)for 4 days.Brain water content was measured by the method of dry and wet weight.The intracranial structure,morphology and signal changes of small animals were observed through T2 weighted image of 7.0 T MRI.The morphological changes of neurons and the apoptosis of nerve cells in the CA1 region of hippocampal tissue were observed by the staining of Nissl and TUNEL.Immunohistochemical staining was performed to observe the extravasation of immunoglobulin G(IgG).The expressions of HIF-1α,AQP4,matrix metalloproteinase-9(MMP-9),claudin-5,occludin and zonula occludens-1(ZO-1)in the tissue of hippocampal were detected by the method of Western blotting and immunofluorescent staining.Results The brain water content increased significantly in the HACE group(P＜0.05).The neurons in CA1 region of hippocampal tissue were atrophic and deformed,the arrangement of neurons was disordered in the HACE group.The number of neurons decreased significantly,the apoptosis of nerve cells increased significantly,and the IgG exudates obviously in the CA1 region of hippocampal tissue in the HACE group.The expressions of HIF-1α,AQP4 and MMP-9 proteins increased significantly,while claudin-5,occludin and ZO-1 proteins decreased significantly in the CA1 region of hippocampal tissue,which detected by the method of Western blotting and immunofluorescent staining(P＜0.05).Conclusion Acute high-altitude hypoxia can induce to blood-brain barrier disruption through the HIF-1α/AQP4 pathway,resulting in high-altitude cerebral edema.

Objective To explore the mediating effect of negative emotion and rumination on the quality of discharge guidance and discharge readiness of patients after coronary artery bypass grafting.Methods A total of 288 patients who underwent coronary artery bypass surgery in the Second Affiliated Hospital of Nanchang University from February 2022 to February 2024 were selected as study objects.General data questionnaire,self-rating anxiety scale(SAS),self-rating depression scale(SDS),Chinese version of event related rumination inventory(CERRI),quality of discharge teaching scale(QDTS),readiness for hospital discharge scale(RHDS)were used to investigate,and Amos 24.0 structural equation model was used to analyze the chain mediation effect.Results A total of 288 questionnaires were sent out,and 280 valid questionnaires were recovered,with an effective recovery rate of 97.22％.The patients'SAS scores were(57.83±5.32)points,SDS scores were(63.31±4.97)points,CERRI total scores were(31.03±4.76)points,QDTS total scores were(116.78±9.22)points,and RHDS total scores were(79.30±7.21)points.The RHDS scores of patients who lived alone after discharge,paid at their own expense and had grade Ⅲ heart function were significantly lower than those of patients with nursing care,medical insurance payment and grade Ⅰ heart function after discharge(P<0.05).Anxiety was positively correlated with depression,intrusive rumination,but negatively correlated with purposive rumination,quality of discharge guidance and discharge readiness.Depression was positively correlated with intrusive rumination,but negatively correlated with purposive rumination,quality of discharge guidance and discharge readiness.Invasive rumination was negatively correlated with purposive rumination,quality of discharge guidance and discharge readiness.Purposive rumination was positively correlated with the quality of discharge guidance and discharge readiness.The quality of discharge guidance was positively correlated with discharge readiness(P<0.05).The chain-mediated model was well fitted,and the results showed that the quality of patients'discharge guidance could affect their discharge readiness,while negative emotions and rumination pathways also affected their discharge readiness(P<0.05).Conclusion The quality of discharge guidance can directly or indirectly affect the discharge readiness of patients after coronary artery bypass grafting through negative emotions and rumination,and there is a chain mediation effect.

Objective:To investigate the effect of low-dose aspirin combined with dydrogesterone in the treatment of patients with polycystic ovary syndrome (PCOS) complicated with infertility and its influence on hormones and helper T cytokines.Methods:300 PCOS patients with infertility in the Second Affiliated Hospital of Air Force Military Medical University were selected from January 2018 to October 2023. A prospective randomized controlled study was performed. The study subjects were divided into control group and observation group by random envelope method, with 150 cases in each group. The control group was treated with dydrogesterone on the basis of routine intervention, while the observation group was combined with low-dose aspirin on the basis of the control group. The efficacy, pregnancy rate, hormones, Th1 and Th2 cytokines and incidence of adverse reactions were compared in between groups. Measurement data with normal distribution was represented by xˉ± s. Comparison between groups was performed by two-sample t-test and paired t-test was used for comparison before and after treatment. Enumeration data was represented by n(%). Comparison between groups was performed by χ2 test. Results:After treatment, the total effective rate of treatment and pregnancy rate in observation group were higher than those in control group [86.00%(129/150) vs. 74.67% (112/150), 63.33% (95/150) vs. 47.33% (71/150)] ( χ2=6.10, P=0.014, χ2=6.73, P=0.010). Serum levels of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) in both groups were lower after treatment than those before treatment, and the levels in observation group were lower than those in control group [(5.27±1.01) U/L vs. (6.40±1.13) U/L, (6.78±0.87) U/L vs. (7.16±0.91) U/L], and serum estradiol level was higher than that before treatment, and the level in observation group was higher compared to control group [(93.35±8.17) ng/L vs. (82.45±9.14) ng/L] ( t=9.13, 3.70, 10.89, all P<0.001). After treatment, serum γ-interferon, interleukin (IL-2), IL-4 and IL-6 levels were all lower in both groups than those before treatment, and the above levels were lower in observation group than those in control group [(56.96±4.64) ng/L vs. (61.36±4.41) ng/L, (38.74±7.43) ng/L vs.(45.63±8.64) ng/L, (41.03±7.06) ng/L vs. (43.36±8.12 ng/L), (23.14±4.33) ng/L vs. (27.14±5.14) ng/L] ( t=8.42, 7.40, 2.65, 7.29, P<0.001, <0.0 010.008, <0.001). There was no statistical significance in the total incidence rate of adverse reactions between observation group and control group [12.67%(22/150) vs. 9.33% (14/150), χ2=0.85, P=0.356]. Conclusions:Low-dose aspirin combined with dydrogesterone has a significant clinical effect in the treatment of PCOS with infertility, and it can improve 3-month pregnancy rate, and effectively regulate hormones levels and Th1 and Th2 cytokines, and it will not increase adverse reactions, with high safety.

After 50 years of clinical development， endoscopic retrograde cholangiopancreatography （ERCP） has become the preferred method for the clinical diagnosis and treatment of cholangio-pancreatic duct diseases； however， the major postoperative complications of ERCP， such as pancreatitis， hemorrhage， and perforation， are still a difficult issue faced by clinicians， and postoperative perforation is associated with an extremely high risk of death. Therefore， it is very important to explore the risk factors for perforation after ERCP， make a definite diagnosis of perforation in a timely manner， and formulate precise prevention and treatment measures. By reviewing a large number of articles， this article summarizes the influencing factors for perforation after ERCP and related diagnosis and treatment measures.

Objective: To analyze the association of eating dining locations and their association with nutritional status among Chinese children aged 6-17 years,so as to provide reference for guiding children s reasonable diet. Methods: Stratified random cluster sampling was used to select children aged 6 to 17 years from 28 cities and rural areas of 14 provinces in East, North, Central, South, Southwest, Northwest, Northeast of China, and a total of 52 535 children were included in the study from 2019 to 2021. Information including dining locations, demographic characteristics, dietary intakes and physical activity were collected through a questionnaire survey. Fasting body height and weight were measured in the morning. Unordered multiclass Logistic regression analysis was conducted to assess the relationship between dining locations and nutritional status in children. Results: Regarding children s dining locations, 66.3% ate breakfast at home,25.8% ate breakfast at school,7.9% ate breakfast outside (small dining tables, restaurants, stalls, etc.); 67.7% ate dinner at home,29.0% ate dinner at school,3.3% ate dinner outside; and 63.6% ate lunch at school,30.8% ate lunch at home,5.7% ate lunch outside. The prevalence rates of overweight/obesity and undernutrition were 28.6% and 9.3%, respectively. The adjusted multiclass Logistic regression analysis (controlling for age, region, parental education, household income, total energy intake, and moderate-to-vigorous physical activity) demonstrated that, compared to eating at home, school based breakfast and dinner consumption was associated with significantly lower overweight/obesity risks for both genders (boys: breakfast OR =0.70, 95% CI =0.65-0.75; dinner OR =0.80, 95% CI = 0.74- 0.86; girls: breakfast OR = 0.89 , 95% CI = 0.82-0.96; dinner OR =0.88, 95% CI =0.81-0.95), whereas eating lunch away from home significantly increased overweight/obesity risks (boys: OR =1.32, 95% CI =1.17-1.48; girls: OR =1.43, 95% CI =1.26- 1.62 ), with all associations being statistically significant ( P <0.05). After adjusting for confounding factors, boys who ate breakfast away from home showed a significantly reduced risk of undernutrition ( OR =0.80,95% CI =0.66-0.97), while those consuming lunch away from home had an increased risk ( OR =1.26, 95% CI =1.01-1.57) ( P <0.05). Conclusions The choice of dining locations for children is becoming more diverse, and a relatively high proportion of children eat meals outside the home and at school. Eating out have a higher risk of malnutrition for children. School feeding may be beneficial to children s physical health.

Objective: Fibromyalgia syndrome (FMS) is a chronic pain condition characterized by central sensitivity to pain, and it is universally acknowledged as a recalcitrant disease. A single-blind randomized controlled trial was conducted to assess the effectiveness and safety of the Roujin formula in treating FMS patients with liver depression and spleen deficiency syndrome, aiming to provide more scientific and effective treatment options. Methods: Forty-eight eligible participants were enrolled and randomly assigned to either the Roujin formula group (n = 24) or the placebo group (n = 24). The Roujin formula group received 150 mL of the Roujin formula twice daily, whereas the placebo group was given a tenth of the Roujin formula dosage, twice daily. The treatment lasted for 8 weeks, with a follow-up extending to 12 weeks. The primary outcome was the improvement in the pain Visual Analogue Scale (VAS) score, whereas secondary outcomes included enhancements in the Pittsburgh Sleep Quality Index (PSQI), Beck Depression Inventory-II (BDI-II), Revised Fibromyalgia Impact Questionnaire (FIQR), and 36-item Short-Form Health Survey (SF-36) scores. These measures were assessed at baseline and after 4, 8, and 12 weeks. The Patients’ Global Impression of Change (PGIC) was collected at week 12. Safety assessments were based on routine blood tests, urine tests, and liver and kidney function evaluations. Results: The improvement in the pain VAS score was significantly greater in the Roujin formula group than that in the placebo group at the 4-, 8-, and 12-week follow-ups (p < 0.05). At the 8-week treatment and the 12-week follow-up, improvements in PSQI and FIQR scores were also superior in the Roujin formula group compared with the placebo group (p < 0.05). There were no differences between the 2 groups in the improvement of BDI-II scores, SF-36 physical component summary, and mental component summary scores at any observation time points. At the 12-week follow-up, PGIC ratings were significantly better in the Roujin formula group (p < 0.05). There were 4 adverse events, all of which occurred in the Roujin formula group, including 3 cases of diarrhea and 1 case of stomach pain; no serious adverse events were reported during the study. Conclusion: The Roujin formula can effectively enhance the overall condition of FMS patients, relieve pain, improve sleep quality, and elevate physical and mental well-being. Only mild gastrointestinal reactions were observed. The Roujin formula may be a viable candidate for clinical implementation.
