Extracorporeal membrane oxygenation (ECMO) is primarily used in clinical practice to provide continuous extracorporeal respiratory and circulatory support for patients with severe heart and lung failure, thereby sustaining life. It is a key technology for managing severe heart failure and respiratory failure that are difficult to control. With the accumulation of clinical experience in ECMO for circulatory and/or respiratory support, as well as advancements in biomedical engineering technology, more portable and stable ECMO devices have been introduced into clinical use, benefiting an increasing number of critically ill patients. Although ECMO technology has become relatively mature, the timing of ECMO initiation, management of sudden complications, and monitoring and early warning of physiological indicators are critical factors that greatly affect the therapeutic outcomes of ECMO. This article reviews traditional methods and artificial intelligence techniques used in risk assessment related to ECMO, including the latest achievements and research hotspots. Additionally, it discusses future trends in ECMO risk management, focusing on six key areas: multi-center and prospective studies, external validation and standardization of model performance, long-term prognosis considerations, integration of innovative technologies, enhancing model interpretability, and economic cost-effectiveness analysis. This provides a reference for future researchers to build models and explore new research directions.

Objective To investigate the distribution and antimicrobial resistance profiles of clinically isolated Haemophilus influenzae and Moraxella catarrhalis in hospitals across China from 2015 to 2021,and provide evidence for rational use of antimicrobial agents.Methods Data of H.influenzae and M.catarrhalis strains isolated from 2015 to 2021 in CHINET program were collected for analysis,and antimicrobial susceptibility testing was performed by disc diffusion method or automated systems according to the uniform protocol of CHINET.The results were interpreted according to the CLSI breakpoints in 2022.Beta-lactamases was detected by using nitrocefin disk.Results From 2015 to 2021,a total of 43 642 strains of Haemophilus species were isolated,accounting for 2.91％of the total clinical isolates and 4.07％of Gram-negative bacteria in CHINET program.Among the 40 437 strains of H.influenzae,66.89％were isolated from children and 33.11％were isolated from adults.More than 90％of the H.influenzae strains were isolated from respiratory tract specimens.The prevalence of β-lactamase was 53.79％in H.influenzae strains.The H.influenzae strains isolated from children showed higher resistance rate than the strains isolated from adults.Overall,779 strains of H.influenzae did not produce β-lactamase but were resistant to ampicillin(BLNAR).Beta-lactamase-producing strains showed significantly higher resistance rates to these antimicrobial agents than the β-lactamase-nonproducing strains.Of the 16 191 M.catarrhalis strains,80.06％were isolated from children and 19.94％isolated from adults.M.catarrhalis strains were mostly susceptible to both amoxicillin-clavulanic acid and cefuroxime,evidenced by resistance rate lower than 2.0％.Conclusions The emergence of antibiotic-resistant H.influenzae due to β-lactamase production poses a challenge for clinical anti-infective treatment.Therefore,it is very important to implement antibiotic resistance surveillance for H.influenzae and guide rational antibiotic use.All local clinical microbiology laboratories should actively improve antibiotic susceptibility testing and strengthen antibiotic resistance surveillance for H.influenzae.

Objective To explore the value of dual factor combined detection using tuberculosis(TB)specific cy-tokines interferon-γ(IFN-γ)and interleukin-2(IL-2)in TB diagnosis in patients with human immunodeficiency vi-rus(HIV)infection,and the influencing factors for underdiagnosis.Methods HIV-infected patients admitted to and underwent TB-related examination in the Department of Infectious Diseases in Hezhou People's Hospital from July 2022 to September 2024 were collected.According to the clinical diagnosis criteria,patients were divided into the HIV infection with TB group(HIV/TB group)and the HIV infection without TB group(control group).Diag-nostic efficacy of dual factor combined detection was evaluated.HIV/TB group was further divided into a true-posi-tive group and a false-negative group based on the detection results.The independent influencing factors for underdia-gnosis was analyzed using multivariate logistic regression.Results A total of 306 patients were included in the analysis,with an average age of(55.69±14.02)years.There were 105 patients in the HIV/TB group and 201 in the control group.The sensitivity and specificity of dual factor combined detection for TB in all HIV-infected pa-tients were 72.4％(76/105)and 87.1％(175/201),respectively.There was a statistically significant difference in sensitivity(x2=9.488,P=0.009)and no statistically significant difference in specificity(x2=5.846,P=0.054)among the three CD4+T lymphocyte count gradients in the dual factor detection.Among them,patients with CD4+T cell count＜100 cells/μL had lower sensitivity(58.8％)in dual factor detection than patients with CD4+T cell count ≥200 cells/μL(88.9％)and 100-199 cells/μL(81.5％),differences were both statistically significant(both P＜0.05).In HIV/TB co-infected patients with CD4+T lymphocyte count ≥100 cells/μL,the general sensi-tivity and the specificity of dual factor combined detection were 85.2％(46/54)and 82.0％(91/111),respectively.Multivariate analysis showed that CD4+T lymphocyte count was an independent influencing factor for the underdia-gnosis in HIV/TB patients conducting dual factor combined detection(P＜0.05),while age,gender,pathogen re-sults,and the presence or absence of TB had no statistically significant impact on the results of dual factor combined detection(all P＞0.05).Conclusion Dual factor combined detection using tuberculosis-specific cytokines IFN-γand IL-2 has a high diagnostic value in the diagnosis of TB in HIV-infected patients,especially in those with CD4+T lymphocyte count ≥100/μL,which can provide auxiliary diagnostic value for the clinical diagnosis of HIV infection combined with TB.

Objective To evaluate the effectiveness of bronchial artery embolization(BAE)combined with surgical lobectomy in treating patients with refractory hemoptysis caused by bronchiectasis.Methods The clinical data of 168 patients with bronchiectasis and refractory hemoptysis,who were treated at the Wuhan Jinyintan Hospital of China from January 2018 to January 2022,were retrospectively analyzed.Of the 168 patients,91 underwent lobectomy(control group),and 71 underwent BAE combined with lobectomy(observation group).The therapeutic efficacy,intraoperative blood loss,surgical operation time,postoperative 3-day drainage volume,length of hospital stay,hemoptysis recurrence rate,and complications were compared between the two groups.Results In the observation group,the clinical efficacy was higher than that in the control group,while the intraoperative blood loss,operation time,length of hospital stay,postoperative 3-day drainage volume and recurrence rate were lower than those in the control group(all P＜0.05).No statistically significant difference in the incidence of complications existed between the two groups(P＞0.05).Conclusion In treating patients with refractory hemoptysis due to bronchiectasis,BAE combined with lobectomy can improve the therapeutic efficacy while not increasing the risk of complications.

Cardiac arrest (CA) is a critical condition in the field of cardiovascular medicine. Despite successful resuscitation, patients continue to have a high mortality rate, largely due to post CA syndrome (PCAS). However, the injury and pathophysiological mechanisms underlying PCAS remain unclear. Experimental animal models are valuable tools for exploring the etiology, pathogenesis, and potential interventions for CA and PCAS. Current CA animal models include electrical induction of ventricular fibrillation (VF), myocardial infarction, high potassium, asphyxia, and hemorrhagic shock. Although these models do not fully replicate the complexity of clinical CA, the mechanistic insights they provide remain highly relevant, including post-CA brain injury (PCABI), post-CA myocardial dysfunction (PAMD), systemic ischaemia/reperfusion injury (IRI), and the persistent precipitating pathology. Summarizing the methods of establishing CA models, the challenges encountered in the modeling process, and the mechanisms of PCAS can provide a foundation for developing standardized CA modeling protocols.
