Background: Intraoperative hypercapnia reduces the time to emergence from volatile anesthetics, but few clinical studies have explored the effect of hypercapnia on the emergence time from intravenous (IV) anesthesia. We investigated the effect of inducing mild hypercapnia during the recovery period on the emergence time after total IV anesthesia (TIVA). Methods: Adult patients undergoing transurethral lithotripsy under TIVA were randomly allocated to normocapnia group (end-tidal carbon dioxide [ETCO2] 35–40 mmHg) or mild hypercapnia group (ETCO2 50-55 mmHg) during the recovery period. The primary outcome was the extubation time. The spontaneous breathing-onset time, voluntary eye-opening time, and hemodynamic data were collected. Changes in the cerebral blood flow velocity in the middle cerebral artery were assessed using transcranial Doppler ultrasound. Results: In total, 164 patients completed the study. The extubation time was significantly shorter in the mild hypercapnia (13.9 ± 5.9 min, P = 0.024) than in the normocapnia group (16.3 ± 7.6 min). A similar reduction was observed in spontaneous breathing-onset time (P = 0.021) and voluntary eye-opening time (P = 0.008). Multiple linear regression analysis revealed that the adjusted ETCO2 level was a negative predictor of extubation time. Middle cerebral artery blood flow velocity was significantly increased after ETCO2 adjustment for mild hypercapnia, which rapidly returned to baseline, without any adverse reactions, within 20 min after extubation. Conclusions Mild hypercapnia during the recovery period significantly reduces the extubation time after TIVA. Increased ETCO2 levels can potentially enhance rapid recovery from IV anesthesia.

Objective To analyze the potential biological relationship between Alzheimer disease(AD)and chronic periodontitis(CP)by bioinformatics.Methods We analyzed two datasets of AD and CP from the Gene Expression Omnibus database,and differentially expressed genes(DEGs)were identified from these datasets.Weighted gene co-expression network analysis(WGCNA)was used to identify the most relevant modules.Functional enrichment analysis of shared genes was performed,and a protein-protein interaction(PPI)network was constructed.MCODE was used to identify key modules,and machine learning was used to discover key genes.In addition,Gene Set Enrichment Analysis(GSEA)and CIBERSORT were used to investigate KLRB1-related molecular pathways and immune cell distribu-tion.Results The study identified 18 genes common to both AD and CP.MCODE analysis revealed five pivotal genes,machine learning identified 13 genes for AD,eight for CP,and KLRB1 was determined as a common gene for AD and CP.GSEA demonstrated the intricate involvement of these genes in disease-related pathways.Immunocellular analysis underscored a significant association between KLRB1 and γδT cells.Conclusion This research highlighted KLRB1 as a key gene for AD and CP,providing new insights into their molecular linkages.

Objective:To analyze the predictive factors associated with late-onset sepsis(LOS) in very low birth weight infants,and to develop a risk prediction score scale applicable to these infants three days postnatal.This will provide valuable insights for early diagnosis and timely intervention.Methods:Very low birth weight infants admitted to the Children's Hospital of Fudan University from January 1,2022,to June 30,2024,were selected as research subjects.These infants were categorized into two groups:the LOS group and the non-LOS group,based on whether they developed LOS.LASSO regression analysis,alongside univariate and multivariate regression analyses,was employed to identify predictive factors for LOS in this population.A Logistic model was constructed using the optimal combination of predictive variables,and a risk assessment scale was subsequently developed.The prediction performance of the model was evaluated using the Hosmer-Lemeshow chi-square test and the receiver operating characteristic curve.Results:A total of 444 cases of very low birth weight infants were included,of which 185 had LOS and 259 did not.After screening the variables,seven independent factors were included into the model:birth weight,gestational age,tracheal intubation,abnormal skin color,abdominal distension,elevated C-reactive protein levels,and right hand perfusion index.A predictive scoring scale was developed based on the regression coefficients of each variable,with corresponding risk scores assigned as follows:1,4,3,2,1,1,and 2; a score of ≥3.5 indicated high-risk groups.The Hosmer-Lemeshow test results demonstrated that χ2 = 7.602( P = 0.473).The area under the receiver operating characteristic curve was 0.792 ( P<0.001),with a sensitivity of 73.5% and specificity of 71.0%. Conclusion:The risk score scale developed in this study exhibits significant predictive capability,providing valuable insights for clinical medical personnel to assess the risk of LOS in very low birth weight infants during the early postnatal period.

Objective The aim of this study was to analyze the incidence and mortality of lymphoma and their changing trends in cancer registration areas of Liaoning Province from 2016 to 2020,and to provide data support for lymphoma prevention and treatment.Methods The data of tumor registration areas in Liaoning province from 2016 to 2020 were collected and sorted out,and the crude incidence,mortality,China standardized incidence and mortality,world standardized incidence and mortality,and cumulative rate of lymphoma were calculated;Joinpoint 5.0.2 software was used to analyze the changing trends of the above indicators from 2016 to 2020.Results From 2016 to 2020,the crude incidence of lymphoma in tumor registration areas of Liaoning Province was 7.43/100,000,age-standardized incidence by Chinese standard population(ASIRC)was 4.07/100,000,and age-standardized incidence by world standard population(ASIRW)was 3.95/100,000;the crude mortality was 4.29/100,000,age-standardized mortality by Chi-nese standard population(ASMRC)was 2.07/100,000,and age-standardized mortality by world standard population(ASMRW)was 2.02/100,000.The ASIRC and ASMRC were higher in males(4.62/100,000 and 2.53/100,000,respectively)than in females(3.56/100,000 and 1.61/100,000,respectively),also higher in urban areas(4.65/100,000 and 2.32/100,000,respectively)than in rural areas(2.46/100,000 and 1.65/100,000,respectively).The incidence and mortality of lymphoma increased with age.The in-cidence reached its peak in the 70-79 age group,and the mortality reached its peak in the 80+age group.From 2016 to 2020,the crude incidence of lymphoma increased from 6.86/100,000 to 8.22/100,000,with a statistically significant trend(APC=5.06％,95％CI;1.13％-9.14％,P=0.026).ASIRC increased from 4.01/100,000 to 4.45/100,000,with no statistical significance(P＞0.05).The crude mortality increased from 3.85/100,000 to 4.53/100,000,while ASMRC decreased from 2.02/100,000 to 2.01/100,000,with no statistically significant trend in the two changes(P＞0.05).Conclusions The incidence and mortality of lymphoma in cancer registration areas of Liaoning Province are higher in men than those of women,and higher in cities than those in rural areas,and reach the peak in the elderly group.The prevention and control of key populations and health management should be strength-ened,especially pay attention to the health needs of the elderly population,and explore possible directions for multidisciplinary collab-orative diagnosis and treatment to reduce the disease burden.

In order to explore the relationship between ubiquitin proteasome system(UPS)and au-tophagy after macrophage was infected with Brucella.On the one hand,the levels of LC3 Ⅱ、P62 and 20S proteasomes in cell supernatant and peritoneal fluid were determined respectively after RAW264.7 cells were infected and BALB/c mice were intraperitoneal inoculated with Brucella suis(B.suis).The results displayed that UPS was activated firstly,followed by autophagy after B.suis infection.On the other hand,we prepared the UPS-inhibited-cells and ALP-inhibited-cells by lacta-cystin and 3-methy ladenine(3-MA),and then the cells were infected by B.suis and the levels of LC3 Ⅱ、P62 与 20S proteasomes in cell supernatant were determined.The results showed that the ALP function was significantly improved when the effect of M

Objective This study aimed to investigate the antimicrobial resistance profiles of bacterial strains isolated from pediatric intensive care units(PICU)in China for better antimicrobial therapy.Methods Clinical isolates were collected from 17 institutions,including tertiary care children's hospitals and pediatric department of tertiary general hospitals in China from January 1,2020 to December 31,2022.Antimicrobial susceptibility testing was carried out according to a unified protocol using Kirby-Bauer method or automated systems.Results were interpreted according to the breakpoints released by the Clinical and Laboratory Standards Institute(CLSI)in 2020.Results A total of 10 688 isolates were collected,including gram-positive organisms(39.2％)and gram-negative organisms(60.8％).The top three organisms were S.aureus(13.6％,1 453/10 688),A.baumannii(10.0％,1 067/10 688),and coagulase-negative Staphylococcus(9.9％,1 058/10 688).Multi-drug resistant organisms(MDROs)were very common in children.The prevalence of methicillin-resistant Staphylococcus aureus(MRSA),carbapenem-resistant Enterobacterales(CRE),carbapenem-resistant E.coli,carbapenem-resistant K.pneumoniae(CRKP),carbapenem-resistant A.baumannii(CRAB),and carbapenem-resistant P.aeruginosa(CRPA)was 41.1％,19.4％,8.8％,30.9％,67.4％,and 28.8％,respectively.Overall,more than 50％of Enterobacteriales isolates were resistant to cephalosporins,while nearly 25％of Enterobacteriales isolates were resistant to carbapenems.MDROs were highly resistant to commonly used antibiotics.More than 80％of CRE and CRAB strains were resistant to all beta-lactam antibiotics.CRE and CRAB showed low resistance rates to tigecycline and polymyxin.CRPA showed lower resistance rates to piperacillin,beta-lactamase inhibitor combinations than the resistance rates to third and fourth generation cephalosporins.All of the Staphylococcus and Enterococcus isolates were susceptible to vancomycin and tigecycline.None of PRSP strains isolated from meningitis and nonmeningitis samples were resistant to rifampicin,vancomycin,or linezolid.The prevalence of β-lactamase-negative ampicillin-resistant(BLNAR)strains was 43.3％in Haemophilus influenzae.Conclusions MDROs were prevalent in PICU.It is necessary to establish an effective multidisciplinary team(MDT)to control the antimicrobial resistance.
