Objective:To explore the causal configurations influencing the career growth of public hospital managers and provide references for promoting their professional development.Methods:From July to December 2023, managers from 9 public hospitals in 3 prefecture-level cities or autonomous prefectures of a central China province were surveyed through a combination of stratified sampling and purposive sampling. The questionnaire included three validated scales: the career growth scale, organizational career management scale, and person-organization fit scale. Using career growth as the outcome variable, and hospital level, organizational career management, person-organization fit, educational background, and employment type as antecedent conditions, fuzzy-set qualitative comparative analysis was applied to identify high-growth configuration pathways.Results:A total of 276 valid questionnaires were collected. Scores for career growth, organizational career management, and person-organization fit were (3.29±0.79), (3.54±0.85), and (3.51±0.85), respectively. The consistency of necessary condition tests for all factors was below 0.9, indicating none were indispensable prerequisites, supporting a configurational analysis of sufficient conditions. Five distinct pathways for career growth of public hospital managers were identified: resource-oriented growth (consistency=0.88), person-organization fit-driven growth (consistency=0.89), organization-dependent growth (consistency=0.91), expertise-driven growth (consistency=0.88), and stable adaptation growth (consistency=0.87). Organizational career management and person-organization fit emerge as core conditions.Conclusions:The study reveals five heterogeneous pathways for managers′ career growth, emphasizing multidimensional complexity. Hospitals should design personalized development plans aligned with pathway characteristics, particularly by strengthening organizational career management and enhancing person-organization fit, to foster managers′ holistic growth and organizational advancement.

AIM:This study aims to investigate the protective effect of α-lipoic acid(α-LA)against alcohol-induced damage in H9c2 rat cardiomyocytes and to explore the underlying mechanisms.METHODS:An alcohol-induced injury model of H9c2 cells was established,and the cells were divided into 4 groups:control group,alcohol group,α-LA group,and alcohol+α-LA group.Additionally,H9c2 cells overexpressing aldehyde dehydrogenase 2(ALDH2)were cre-ated and further divided into 6 groups:normal control group,normal cells treated with alcohol group,normal cells treated with alcohol+α-LA group,ALDH2 overexpression group,ALDH2-overexpressing cardiomyocytes treated with alcohol group,and ALDH2-overexpressing cardiomyocytes treated with alcohol+α-LA group.Cell proliferation was assessed using 5-ethynyl-2'-deoxyuridine(EdU)staining.Reactive oxygen species(ROS)levels in each group were measured using di-hydroethidium(DHE)staining,while the expression levels of ALDH2,silent information regulator 1(SIRT1),heme oxy-genase 1(HO1)and P53 proteins were detected by Western blot analysis.RESULTS:(1)Alcohol exposure resulted in a decrease in the proliferation of H9c2 cells and an increase in intracellular oxidative stress,evidenced by elevated ROS levels and decreased expression of related proteins(ALDH2,SIRT1 and HO1).However,α-LA treatment significantly mitigated the decline in cell proliferation and the oxidative stress induced by alcohol.(2)Alcohol may induce cellular se-nescence,as demonstrated by the up-regulation of P53 expression,which were reversed by α-LA.(3)The H9c2 cells with high ALDH2 expression markedly improved the cell proliferation in the presence of alcohol,suppressed the ROS pro-duction,prevented the down-regulation of oxidative stress-related proteins(ALDH2,SIRT1 and HO1),and reversed the enhanced expression of the senescence marker P53.CONCLUSION:Treatment with α-LA may counteract oxidative stress and attenuate cellular senescence by activating ALDH2,thereby protecting cardiomyocytes from alcohol-induced damage.

With the popularization and development of modern imaging techniques,a phenomenon of rapid progression of coronary atherosclerosis with increasing risk of cardiovascular events has attracted more attention.Rapid progression of coronary atherosclerosis is related to a variety of pathophysiological mechanisms,such as iatrogenic injury,subclinical cycle of plaque rupture and healing,inflammation and so on.Predictive value of plaque morphological features,glycolipid-related metabolites and inflammatory factors for rapid progression of coronary atherosclerosis has been intensively studied.Lipid-lowering therapy is currently the main method to hinder the rapid plaque progression,and new effective therapeutic targets are still under investigations.In this review,we summarize the pathophysiology,predictors,evaluation methods and treatments of rapid progression of coronary atherosclerosis,aiming to provide useful information for the clinical practice.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective:To investigate the early clinical characteristics of elderly patients with severe burns and the risk factors on prognosis.Methods:This study was a retrospective case series study. Clinical data of 124 elderly patients with severe burns who met the inclusion criteria and were admitted to the 12 hospitals from January 2015 to December 2020 were collected, including 4 patients from the Fourth People's Hospital of Dalian, 5 patients from Fujian Medical University Union Hospital, 22 patients from Guangzhou Red Cross Hospital of Jinan University, 5 patients from Heilongjiang Provincial Hospital, 27 patients from the First Affiliated Hospital of Naval Medical University, 9 patients from the First Affiliated Hospital of Nanchang University, 10 patients from Affiliated Hospital of Nantong University, 9 patients from Tongren Hospital of Wuhan University & Wuhan Third Hospital, 12 patients from the 924 th Hospital of PLA, 6 patients from Zhangjiagang First People's Hospital, 4 patients from Taizhou Hospital of Zhejiang Province, and 11 patients from Zhengzhou First People's Hospital. The patients' overall clinical characteristics, such as gender, age, body mass index, total burn area, full-thickness burn area, inhalation injury, causative factors, whether combined with underlying medical diseases, and admission time after injury were recorded. According to the survival outcome within 28 days after injury, the patients were divided into survival group (89 cases) and death group (35 cases). The following data of patients were compared between the two groups, including the basic data and injuries (the same as the overall clinical characteristics ahead); the coagulation indexes within the first 24 hours of injury such as prothrombin time (PT), activated partial thromboplastin time (APTT), thrombin time, D-dimer, fibrinogen degradation product (FDP), international normalized ratio (INR), and fibrinogen; the blood routine indexes within the first 24 hours of injury such as white blood cell count, platelet count, neutrophil-to-lymphocyte ratio, monocyte count, red blood cell count, hemoglobin, and hematocrit; the organ function indexes within the first 24 hours of injury such as direct bilirubin, total bilirubin, urea, serum creatinine, aspartate aminotransferase, alanine aminotransferase, total protein, albumin, globulin, blood glucose, triglyceride, total cholesterol, alkaline phosphatase, creatine kinase, electrolyte indexes (potassium, sodium, chlorine, calcium, magnesium, and phosphorus in blood), uric acid, myoglobin, and brain natriuretic peptide; the infection and blood gas indexes within the first 24 hours of injury such as procalcitonin, C-reactive protein, pH value, oxygenation index, base excess, and lactate; treatment such as whether conducted with mechanical ventilation, whether conducted with continuous renal replacement therapy, whether conducted with anticoagulation therapy, whether applied with vasoactive drugs, and fluid resuscitation. The analysis was conducted to screen the independent risk factors for the mortality within 28 days after injury in elderly patients with severe burns. Results:Among 124 patients, there were 82 males and 42 females, aged 60-97 years, with body mass index of 23.44 (21.09, 25.95) kg/m 2, total burn area of 54.00% (42.00%, 75.00%) total body surface area (TBSA), and full-thickness burn area of 25.00% (10.00%, 40.00%) TBSA. The patients were mainly combined with moderate to severe inhalation injury and caused by flame burns. There were 43 cases with underlying medical diseases. The majority of patients were admitted to the hospital within 8 hours after injury. There were statistically significant differences between patients in the 2 groups in terms of age, total burn area, full-thickness burn area, and inhalation injury, and PT, APTT, D-dimer, FDP, INR, white blood cell count, platelet count, urea, serum creatinine, blood glucose, blood sodium, uric acid, myoglobin, and urine volume within the first 24 hours of injury (with Z values of 2.37, 5.49, 5.26, 5.97, 2.18, 1.95, 2.68, 2.68, 2.51, 2.82, 2.14, 3.40, 5.31, 3.41, 2.35, 3.81, 2.16, and -3.82, respectively, P<0.05); there were statistically significant differences between two groups of patients in whether conducted with mechanical ventilation and whether applied with vasoactive drugs (with χ2 values of 9.44 and 28.50, respectively, P<0.05). Age, total burn area, full-thickness burn area, serum creatinine within the first 24 hours of injury, and APTT within the first 24 hours of injury were the independent risk factors for the mortality within 28 days after injury in elderly patients with severe burns (with odds ratios of 1.17, 1.10, 1.10, 1.09, and 1.27, 95% confidence intervals of 1.03-1.40, 1.04-1.21, 1.05-1.19, 1.05-1.17, and 1.07-1.69, respectively, P<0.05). Conclusions:The elderly patients with severe burns had the injuries mainly from flame burns, often accompanied by moderate to severe inhalation injury and enhanced inflammatory response, elevated blood glucose levels, activated fibrinolysis, and impaired organ function in the early stage, which are associated with their prognosis. Age, total burn area, full-thickness burn area, and serum creatinine and APTT within the first 24 hours of injury are the independent risk factors for death within 28 days after injury in this population.

Acute ST-segment elevation myocardial infarction with multivessel disease is one of the high-risk types of coronary heart disease.Early opening of infarct-related artery and reperfusion of myocardium could significantly reduce the mortality in acute phase.However,the presence of non-culprit lesions in non-infarct-related arteries is still at risk and has an important impact on the long-term prognosis of patients.It remains controversial on how to precisely evaluate the clinical significance and revascularization value of non-culprit lesions.This article aims to review the research status and progress of guidance strategies of non-culprit lesion revascularization in patients with ST-segment elevation myocardial infarction and multivessel disease.

Recently,small nucleolar RNAs(snoRNAs)have transcended the genomic"noise"to emerge as pivotal molecular markers due to their essential roles in tumor progression.Substantial evidence indicates a strong association between snoRNAs and critical clinical features such as tumor pathology and drug resistance.Historically,snoRNA research has concentrated on two classical mechanisms:2'-O-ribose methylation and pseudouridylation.This review specifically summarizes the novel regulatory mecha-nisms and functional patterns of snoRNAs in tumors,encompassing transcriptional,post-transcriptional,and post-translational regulation.We further discuss the synergistic effect between snoRNA host genes(SNHGs)and snoRNAs in tumor progression.More importantly,snoRNAs extensively contribute to the development of tumor cell resistance as oncogenes or tumor suppressor genes.Accordingly,we provide a comprehensive review of the clinical diagnosis and treatment associated with snoRNAs and explore their significant potential as novel drug targets.
