ObjectiveTo investigate the mechanism of action of remifentanil （RMZL） in alleviating lung ischemia-reperfusion injury （LIRI） in rats by inhibiting pyroptosis through modulating hypoxia inducible factor-1α （HIF-1α）/NOD-like receptor thermal protein domain associated protein 3 （NLRP3） pathway. MethodsRats were stochastically assigned into Control group， LIRI group， RMZL low-dose group， RMZL medium-dose group， RMZL high-dose group， and RMZL high-dose+HIF-1α activator dimethyloxallyl glycine （DMOG） group， with 18 rats in each group. Rats in Control group only had their left pulmonary hilum free and did not undergo ischemia-reperfusion treatment. Except for the Control group， LIRI models were constructed in all other groups. Rats in LIRI group were intraperitoneally injected with an equal amount of physiological saline 15 minutes before constructing LIRI model； rats in Control group were intraperitoneally injected with an equal amount of physiological saline 15 minutes before freeing left pulmonary hilum； rats in other groups were intraperitoneally injected with corresponding dose of drug 15 minutes before constructing LIRI model. The wet/dry weight ratio of lungs was calculated. HE staining was used to study lung tissue pathology. Immunofluorescence staining was used to detect the relative fluorescence intensity of gasdermin D （GSDMD） and NLRP3 double positive cells in lung tissue. ELISA was used to detect interleukin-1β and IL-18 in lung tissue. Western blot was used to detect HIF-1α， NLRP3， cysteine-aspartic protease-1 （Cleaved caspase-1）， and gasdermin D-N （GSDMD-N） proteins in lung tissue. ResultsCompared to the Control group， the LIRI group showed disordered alveolar structure， thickened alveolar septa， and abundant inflammatory cell infiltration in rats. The lung wet/dry weight ratio， relative fluorescence intensity of GSDMD and NLRP3 double positive cells in lung tissue， IL-1β， IL-18 levels， and HIF-1α， NLRP3， Cleaved caspase-1， and GSDMD-N proteins increased （P0.05）. For the LIRI group， rats in the RMZL low， medium， and high-dose groups displayed attenuated alveolar septal thickening and reduced inflammatory cell infiltration. The lung wet/dry weight ratio， relative fluorescence intensity of GSDMD and NLRP3 double positive cells in lung tissue， IL-1β， IL-18 levels， and HIF-1α， NLRP3， Cleaved caspase-1， and GSDMD-N proteins declined， and the RMZL high-dose group showed the most prominent trend （P0.05）. Compared with the RMZL high-dose group， rats in the RMZL high-dose+DMOG group exhibited thickened alveolar septa and more inflammatory cell infiltration， along with increased lung wet/dry weight ratio， relative fluorescence intensity of GSDMD and NLRP3 double positive cells in lung tissue， levels of IL-1β and IL-18， and protein expression of HIF-1α， NLRP3， Cleaved caspase-1， and GSDMD-N （P0.05）. ConclusionRMZL may inhibit pyroptosis in LIRI rats by suppressing HIF-1α/NLRP3 pathway.

Creutzfeldt-Jakob disease(CJD)is a rapidly progressive and fatal neurodegenerative disorder caused by prions,with certain infectivity and iatrogenic transmission risks.With the rapid progress and application of new dia-gnostic biomarkers and detection methods,as well as the construction and improvement of surveillance and reporting systems,the detection of CJD in patients domestically and internationally has shown an increasing trend year by year.Due to its long incubation period and heterogeneity of early symptoms,early identification and diagnosis of the disease is difficult,increasing the risk of transmission within medical institutions.Currently,there is a lack of con-sensus on the infection prevention and control of CJD.In order to timely identify and diagnose CJD as well as effec-tively block its transmission in medical institutions,this consensus summarizes 15 clinical concerns and formulates 24 specific recommendations based on the latest domestic and international research findings and clinical evidence,as well as combines with clinical practice,aiming to standardize healthcare-associated infection prevention and control measures for CJD and reduce its transmission risk in medical institutions.

Objective To develop a platform for reporting medication near miss events and evaluate its application effectiveness,aiming to enhance medication safety of patients.Methods Based on literature review,qualitative interviews,and expert group meetings,a medication near-miss event reporting platform was constructed,including 4 modules:event content filling,event risk grading,event handling,and statistical analysis.50 nurses were conveniently selected from the pediatric ward of a tertiary grade A hospital in Henan Province as the application subjects.The reporting situation and filling duration of medication near miss events,the score of the Medication Near Miss Reporting Disorder Scale,and the incidence of medication near miss events were compared after the application of the platform(from March to August 2023)and before the application(from September 2022 to February 2023).Results The reporting rate of medication near miss events after the application of the platform was higher than that before the application of the platform,and the comparison of the distribution of event nature and occurrence links showed statistically significant differences(P＜0.05).After the application of the platform,the reporting duration of medication near miss events was shorter than that before the application of the platform,and the score of the Medication Near Miss Reporting Disorder Scale was lower than that before the application of the platform.The differences were statistically significant(P＜0.001).There was no statistically significant difference in the incidence of medication near miss events before and after the application of the platform(P=0.241).Conclusion Using this platform can help improve the reporting rate of medication near miss events,reduce the time taken to fill out reports,and minimize reporting barriers for nurses.

The global burden of obesity continues to rise, and the long-term management of body weight remains a significant challenge. Virtually all current weight loss interventions are associated with varying degrees of weight regain following initial weight reduction, which compromises the long-term benefits for patients with obesity. Multiple complex physiological mechanisms contribute to this phenomenon, including the regulation of body weight " set points" , alterations in energy expenditure and metabolic adaptation, central nervous system control, and the modulatory effects of obesity-associated immune cells. Targeted interventions addressing these regulatory pathways may help mitigate weight regain. In recent years, several novel therapeutic strategies have emerged, such as nutrient-stimulated hormone-based agents, compounds that enhance the efficacy of glucagon-like peptide-1 receptor agonists, leptin-sensitizing agents, and medications that improve body composition. These innovations offer promising opportunities to sustain weight loss and prevent subsequent regain. This review aims to summarize the underlying mechanisms of weight regain and discuss emerging strategies to address this challenge, providing new perspectives for optimizing the long-term clinical management of obesity.

Objective:To investigate the multimorbidity of myopia and obesity, as well as myopia and malnutrition, among children and adolescents aged 7-18 in Guangdong Province and analyze their epidemiological characteristics and related factors.Methods:A stratified random cluster sampling method was used to select 274 939 children and adolescents aged 7-18 from 21 cities in Guangdong Province in 2023. Physical examination information such as height, weight, distance vision, and diopter, as well as questionnaire survey information on dietary behavior, physical activity, screen behavior, sleep time, etc., were collected to analyze the current status and trends of multimorbidity between myopia and obesity, myopia and malnutrition. The multivariate logistic regression model was used to analyze the related factors of multimorbidity.Results:The multimorbidity rates of myopia and obesity, myopia and malnutrition in children and adolescents aged 7-18 in Guangdong Province in 2023 were 4.43% and 6.40%, respectively. The multimorbidity rates for males were 5.44% and 6.88%, respectively, which were higher than those for females, about 3.31% and 5.88% (both P<0.001). The multimorbidity rates of urban students were 5.03% and 6.73%, respectively, which were higher than those of county students at 4.03% and 6.18% (both P<0.001). The multimorbidity rates of myopia and obesity, myopia and malnutrition increased with the increase of academic stage (all P<0.001). The multimorbidity rates of myopia and obesity, as well as myopia and malnutrition, fluctuated with age, with the first decrease occurring at the age of 12. The multivariate logistic regression analysis showed that compared to children and adolescents aged 7-18 who had daily after-school tutoring <2 hours, daily screen time <2 hours, did not consume sugary drinks every day, sleep time that could meet health requirements daily, and exercised≥60 minutes of moderate-to vigorous-physical activity ≥60 minutes for at least 3 days per week, those who had daily after-school tutoring ≥2 hours ( OR=1.18, 95% CI: 1.11-1.26), daily screen time ≥2 hours ( OR=1.09, 95% CI: 1.02-1.16), consumed sugary drinks every day ( OR=1.20, 95% CI: 1.11-1.30), daily sleep time that could not meet the health requirements ( OR=1.16, 95% CI: 1.09-1.23), and no exercise per week ( OR=1.09, 95% CI: 1.01-1.18) had a higher risk of multimorbidity of myopia and obesity. Compared to children and adolescents who exercised≥60 minutes of moderate-to vigorous-physical activity ≥60 minutes for at least 3 days per week, those who exercised <3 days per week ( OR=1.20, 95% CI: 1.17-1.34) had a higher risk of multimorbidity of myopia and malnutrition. Conclusion:The multimorbidity rates of myopia and obesity, as well as myopia and malnutrition, in children and adolescents aged 7-18 in Guangdong Province are relatively low and fluctuate with age. Physical activity, screen time, consumption of sugary drinks, and sleep time may be associated with these multimorbidities.

Therefore, there is an urgent need to develop a standardized, high-quality visualization telemedicine round system .Therefore, experts have been organized to search domestic and foreign literature on telemedicine round for critically ill patients and to form this consensus based on clinical experiences so as to further improve the level of critical care treatments in regions.

Objective Estimating the residual risk of transfusion-transmitted diseases in voluntary blood donors is crucial for monitoring blood safety.and to analyze the evolution trend over a five-year period in Yantai,Shandong Province.Methods This study retrospectively reviewed screening data from Yantai Central Blood Station between 2018 and 2022.We compared the positivity rates between first-time and repeat donors,calculated the prevalence of each virus,and estimated the residual risk using the prevalence-window period model.Meanwhile,the age characteristics of all positive donors were analyzed.Results Over the five-year period,a total of 320 016 individuals donated blood.The overall reaction rate of transfusion-transmitted diseases was 0.165%,with HBV(0.129%)being the most common.The positivity rate among first-time donors[P(FTDs)](0.310%)was significantly higher than that among repeat donors[P(RDs)](0.054%)(χ2=312.783,P<0.05).The serological residual risks for HBV,HCV,and HIV were 1∶188 090,1∶1 042 805,and 1∶392 995,respectively.During the five-year period,they decreased from 1∶129 495 to 1∶390 011,from 1∶697 002 to 1∶1 145 826,and from 1∶684 109 to 1∶1 067 317,respectively.The residual risks of HCV and HIV after NAT were 1∶22 369 329 and 1∶6 639 965,respectively,which were significantly reduced by 21.5-fold and 16.9-fold,and decreased steadily during the study period.Among the HBV-DNA(+)donors,61.8%(68/110)were RDs,and the residual risk was 1∶65 350.Conclusion This study demonstrates the remarkable effectiveness of introducing nucleic acid amplification technology(NAT)in reducing the residual risk of HBV,HCV,and HIV,particularly for HCV and HIV.The residual risk for HBV remains higher compared to HCV and HIV due to the discovery of occult HBV infections(OBI).Therefore,a crucial step toward further reducing this residual risk is the use of more sensitive reagents and detection platforms.Furthermore,implementing effective long-term incentive mechanisms and strategic planning to increase the proportion of repeat donors(RDs)is critical for enhancing transfusion safety.

Objective:To explore the application effect of continuous intravenous infusion of lidocaine on patients undergoing transnasal pituitary tumor resection.Methods:Ninety patients undergoing transsphenoidal pituitary tumor resection under general anesthesia from May 2022 to January 2025 were selected.The participants were randomly divided into two groups:a control group and a lidocaine group,with 45 patients in each group.Before starting anesthesia,the lidocaine group received intravenous injection of 1.5 mg/kg lidocaine,followed by continuous intravenous injection at a rate of 2 mg/(kg·h)throughout the entire surgical process.The control group received an equal amount of physiological saline.The other anesthesia regimens and drugs for the two groups of patients were consistent,and all anesthesia related drugs were stopped from infusion at the end of the surgery.Compare the intraoperative mean arterial pressure(MAP)and heart rate changes between two groups,evaluate visual analog scale(VAS)scores at different time points,postoperative opioid dosage and recovery level,and incidence of adverse reactions.Results:There was a certain degree of fluctuation in MAP and heart rate in both groups during the operation,with the lidocaine group showing a smaller level of fluctuation.There was no significant difference in MAP and heart rate levels between the two groups at T1 and T6 times(P＞0.05),while the MAP and heart rate levels in the lidocaine group were higher than those in the control group at T2,T3,T4,and T5 times(P＜0.05);Compared with the control group,there was no statistically significant difference in VAS scores between the two groups at T0 time(P＞0.05).The VAS scores of the two groups showed an upward trend at T1,T2,T3,and T4 time,and a downward trend at T5 time.However,the VAS scores of the lidocaine group were lower than those of the control group at T1,T2,T3,T4,and T5 time(P＜0.05);The dose of remifentanil administered via intravenous pump during the lidocaine group,the duration of first postoperative ventilation,and the length of hospital stay were all lower than those in the control group(P＜0.05);The incidence of nausea,vomiting,and coughing related adverse reactions in the lidocaine group was lower than that in the control group(P＜0.05).Conclusion:Lidocaine assisted intravenous anesthesia can promote stable hemodynamic fluctuations during pituitary adenoma resection surgery,reduce postoperative pain,decrease opioid dosage,shorten hospital stay,and reduce adverse reactions such as coughing,nausea,and vomiting.

As a multifactorial chronic metabolic disorder with complex causes and serious health risks, obesity has drawn significant societal and medical attention. This article systematically reviewed the latest advancements in the clinical diagnosis and treatment of obesity. A disease-centered diagnosis and treatment concept has been proposed, which combines BMI and introduces a brand-new clinical diagnosis and treatment standard centered on fat content and functional disorders, such as new diagnostic markers like adipose tissue distribution, visceral adiposity, and waist-to-height ratio, to conduct a comprehensive assessment and lifespan management of patients. In recent years, novel biomarkers and artificial intelligence (AI)-assisted diagnosis have provided new tools for the diagnosis and treatment of obesity. In terms of treatment, combined therapy based on lifestyle and behavioral intervention has been widely recognized. The advent of new weight-loss drugs, such as glucagon-like peptide-1(GLP-1), minimally invasive techniques such as endoscopic sleeve gastrectomy(ESG), which reduced surgical risks, have provided possibilities for the treatment of obesity. The current concept of obesity management has become increasingly mature, feasible, and standardized. The construction principles of a weight management center, characterized by centralized management and individualized treatment, ensure the long-term stability of body weight and promote a healthy quality of life for patients with obesity.
