Objective To explore characteristics of time-domain and time-frequency of task-related electroencephalogram(EEG)in patients with post-stroke aphasia(PSA).Methods From January,2018 to December,2021,18 PSA patients(PSA group)were recruited from Dongzhimen Hospi-tal,Beijing University of Chinese Medicine,and nine healthy subjects(control group)were recruited with matched gender,age and education level.EEG data based on the Chinese word-picture matching task were col-lected,and the average amplitude of N400 and event-related synchronization(ERS)/desynchronization(ERD)were analyzed.The PSA group was assessed with Chinese Rehabilitation Research Center Aphasia Examination(CRRCAE).Results The effect of N400 was significant on left frontal,central frontal,right frontal,left central and central areas.The average amplitude of N400 was higher on the frontal area in PSA group than in the control group,and it was low-er on right temporal-parietal area.For word-picture mismatching,average amplitude of N400 at FPZ was moder-ately correlated with auditory comprehension(r=0.483,P<0.05),the average amplitude of N400 at T8 was moderately correlated with repetition(r=0.584,P<0.05)and reading aloud(r=0.556,P<0.05),and the aver-age amplitude of N400 at P6 was moderately correlated with speaking(r=0.476,P<0.05)and reading(r=0.502,P<0.05).For word-picture matching,the average amplitude of N400 at P7 was moderately negatively cor-related with calculation(r=-0.481,P<0.05).Compared with the control group,the energy decreased in θ and αfrequency bands with absence of ERS in PSA group,and it increased in β frequency band with absence of ERD.Conclusion The activities of Chinese word-picture matching task-related EEG have been inhibited on right temporal-pa-rietal area for PSA patients,and it compensatively increases on frontal area,while the energy decreases in θ and αfrequency bands with ERS deficiency,and increases in β frequency band with ERD deficiency.

Although a single nucleotide polymorphism for N-acetyltransferase 10 (NAT10) has been identified in patients with early-onset stroke, the role of NAT10 in ischemic injury and the related underlying mechanisms remains elusive. Here, we provide evidence that NAT10, the only known RNA N4-acetylcytidine (ac4C) modification "writer", is increased in the damaged cortex of patients with acute ischemic stroke and the peri-infarct cortex of mice subjected to photothrombotic (PT) stroke. Pharmacological inhibition of NAT10 with remodelin on Days 3-7 post-stroke or astrocytic depletion of NAT10 via targeted virus attenuates ischemia-induced infarction and improves functional recovery in PT mice. Mechanistically, NAT10 enhances ac4C acetylation of the inflammatory cytokine tissue inhibitor of metalloproteinase 1 (Timp1) mRNA transcript, which increases TIMP1 expression and results in the accumulation of microtubule-associated protein 1 light chain 3 (LC3) and progression of astrocyte autophagy. These findings demonstrate that NAT10 regulates astrocyte autophagy by targeting Timp1 ac4C after stroke. This study highlights the critical role of ac4C in the regulation of astrocyte autophagy and proposes a promising strategy to improve post-stroke outcomes via NAT10 inhibition.

OBJECTIVE To explore the clinical characteristics and risk factors for refractory drug-resistant Pseudo-monas aeruginosa infection and evaluate the prognosis so as to provide theoretical bases for effective prevention and control of the refractory drug-resistant P.aeruginosa infection.METHODS A total of 95 patients who were di-agnosed with refractory drug-resistant P.aeruginosa infection and were treated in People's Hospital of Guangdong Province from Jan.2019 to Dec.2023 were assigned as the infection group.Meanwhile,95 patients who did not have drug-resistant P.aeruginosa infection,matched by the age and hospitalization period,were chosen as the non-infection group in a case-control(1∶1 ratio).The basic information and clinical data were collected from the two groups of patients.The characteristics and risk factors for the drug-resistant P.aeruginosa infection were ana-lyzed,and the prognosis of the patients was evaluated.RESULTS Among the clinical isolates of drug-resistant P.aeruginosa,78 were isolated from respiratory secretions;there were 59 patients from intensive care unit(ICU),13 patients from respiratory medicine department and 8 patients from geriatrics department.Fever,dyspnea,moist rales and cough were the major clinical manifestations.The proportions of patients with history of respirato-ry tract disease(P＜0.001),renal disease(P=0.008),nervous system disease(P=0.005),diabetes mellitus(P=0.017),hepatic disease(P=0.007),previous utilization rate of aminoglycosides(P=0.002)and previous u-tilization rate of no less than 3 types of antibiotics were higher in the infection group than in the non-infection group.Multivariate analysis showed that the history of respiratory tract disease(OR=2.813,95％CI:1.366 to 5.792,P=0.005),history of diabetes mellitus(OR=2.465,95％CI:1.129 to 5.382,P=0.024)and history of nervous system disease(OR=2.386,95％CI:1.151 to 4.944,P=0.019)were the risk factors for the drug-resist-ant P.aeruginosa infection.The mortality rate of the infection group was 30.53％,higher than 6.32％of the non-infection group(x2=18.527,P＜0.001).CONCLUSIONS The mortality rate of the patients with drug-resistant P.aeruginosa infection is high.The history of respiratory tract disease,history of diabetes mellitus and history of nervous system disease are the major risk factors for the infection.It is necessary for the hospital to strengthen the awareness of prevention of the drug-resistant P.aeruginosa infection so as to curb the hospital-associated infection.

Game-based psychological assessment utilizes game mechanisms and elements to enhance partic-ipants'motivation and improve measurement accuracy,but similar to traditional methods,it mainly focuses on static results.By integrating game-based psychological assessment with artificial intelligence technology,this paper propo-ses the paradigm of intelligent psychological assessment based on interactive environment.With analyzing dynamic process data within the game,this paradigm can accurately depict the participants'actions and results in the interac-tive context,more effectively representing individual psychological states and behavioral characteristics.This new paradigm demonstrates advancements and significant potential for development in terms of demand,data collection,and analysis techniques.

Objective:The drug-resistant genes carried by carbapenem-resistant Klebsiella pneumoniae(CRKP)limit clinical treatment options,and its virulence genes severely affect patient prognosis.This study aims to investigate the distribution of virulence genes,capsular serotypes,and molecular epidemiological characteristics of CRKP in ICU,to understand the characteristics of CRKP infections in ICU,and to provide a scientific basis for effective monitoring and control of CRKP infections in ICU. Methods:A total of 40 non-duplicate strains of CRKP isolated from the ICU of Guangdong Provincial People's Hospital between January 2021 and December 2022 were collected and analyzed.Whole-genome sequencing was used to analyze the distribution of resistance genes,virulence genes,and capsular serotypes of the strains.The sequences of 7 housekeeping genes of CRKP genome were uploaded to the Klebsiella pneumoniae(KPN)multilocus sequence typing(MLST)database to determine the sequence types(STs)of the strains. Results:The age of the 40 ICU CRKP-infected patients was(69.03±17.82)years old,with various underlying diseases,and there were 20 patients with improved clinical outcome and 20 patients with death.The isolated strains primarily originated from mid-stream urine and bronchoalveolar lavage fluid.Whole-genome sequencing results revealed that the strains predominantly carried blaKPC-1(29 strains,72.5%)and blaNDM-1(6 strains,15.0%),with 5 strains carrying both blaKPC-1 and blaNDM-1.Various virulence genes were detected,among which the carriage rates of genes such as entA,entB,entE,entS,fepA,fepC,fepG,yag/ecp,and ompA reached 100%,while the carriage rates of genes such as entD,fimB,iroB,iroD,fes,and pla were low.The CRKP strains isolated from ICU were predominantly ST11(27 cases,67.5%),with KL64 being the main capsular serotype(29 cases,72.5%).A total of 23 ST11-KL64 CRKP strains were detected,accounting for 57.5%. Conclusion:The main type of ICU CRKP is ST11-KL64,carrying various virulence genes,primarily those related to iron absorption.Furthermore,blaKPC has shifted from blaKPC-2 to blaKPC-1.Therefore,close monitoring of the molecular epidemiological changes of CRKP is necessary,and strict control measures should be implemented to effectively curb the occurrence of CRKP infections.
