Background::Hepatic ischemia-reperfusion injury (HIRI) remains a common complication during liver transplantation (LT) in patients. As a key downstream effector of the Hippo pathway, Yes-associated protein (YAP) has been reported to be involved in various physiological and pathological processes. However, it remains elusive whether and how YAP may control autophagy activation during ischemia-reperfusion.Methods::Human liver tissues from patients who had undergone LT were obtained to evaluate the correlation between YAP and autophagy activation. Both an in vitro hepatocyte cell line and in vivo liver-specific YAP knockdown mice were used to establish the hepatic ischemia-reperfusion models to determine the role of YAP in the activation of autophagy and the mechanism of regulation. Results::Autophagy was activated in the post-perfusion liver grafts during LT in patients, and the expression of YAP positively correlated with the autophagic level of hepatocytes. Liver-specific knockdown of YAP inhibited hepatocytes autophagy upon hypoxia-reoxygenation and HIRI ( P <0.05). YAP deficiency aggravated HIRI by promoting the apoptosis of hepatocytes both in the in vitro and in vivo models ( P <0.05). Attenuated HIRI by overexpression of YAP was diminished after the inhibition of autophagy with 3-methyladenine. In addition, inhibiting autophagy activation by YAP knockdown exacerbated mitochondrial damage through increasing reactive oxygen species ( P <0.05). Moreover, the regulation of autophagy by YAP during HIRI was mediated by AP1 (c-Jun) N-terminal kinase (JNK) signaling through binding to the transcriptional enhanced associate domain (TEAD). Conclusions::YAP protects against HIRI by inducing autophagy via JNK signaling that suppresses the apoptosis of hepatocytes. Targeting Hippo (YAP)-JNK-autophagy axis may provide a novel strategy for the prevention and treatment of HIRI.

Background::Although overnight fasting is recommended prior to endoscopic retrograde cholangiopancreatography (ERCP), the benefits and safety of high-carbohydrate fluid diet (CFD) intake 2 h before ERCP remain unclear. This study aimed to analyze whether high-CFD intake 2 h before ERCP can be safe and accelerate patients’ recovery.Methods::This prospective, multicenter, randomized controlled trial involved 15 tertiary ERCP centers. A total of 1330 patients were randomized into CFD group ( n = 665) and fasting group ( n = 665). The CFD group received 400 mL of maltodextrin orally 2 h before ERCP, while the control group abstained from food/water overnight (>6 h) before ERCP. All ERCP procedures were performed using deep sedation with intravenous propofol. The investigators were blinded but not the patients. The primary outcomes included postoperative fatigue and abdominal pain score, and the secondary outcomes included complications and changes in metabolic indicators. The outcomes were analyzed according to a modified intention-to-treat principle. Results::The post-ERCP fatigue scores were significantly lower at 4 h (4.1 ± 2.6 vs. 4.8 ± 2.8, t = 4.23, P <0.001) and 20 h (2.4 ± 2.1 vs. 3.4 ± 2.4, t= 7.94, P <0.001) in the CFD group, with least-squares mean differences of 0.48 (95% confidence interval [CI]: 0.26–0.71, P <0.001) and 0.76 (95% CI: 0.57–0.95, P <0.001), respectively. The 4-h pain scores (2.1 ± 1.7 vs. 2.2 ± 1.7, t = 2.60, P = 0.009, with a least-squares mean difference of 0.21 [95% CI: 0.05–0.37]) and positive urine ketone levels (7.7% [39/509] vs. 15.4% [82/533], χ2 = 15.13, P <0.001) were lower in the CFD group. The CFD group had significantly less cholangitis (2.1% [13/634] vs. 4.0% [26/658], χ2 = 3.99, P = 0.046) but not pancreatitis (5.5% [35/634] vs. 6.5% [43/658], χ2 = 0.59, P = 0.444). Subgroup analysis revealed that CFD reduced the incidence of complications in patients with native papilla (odds ratio [OR]: 0.61, 95% CI: 0.39–0.95, P = 0.028) in the multivariable models. Conclusion::Ingesting 400 mL of CFD 2 h before ERCP is safe, with a reduction in post-ERCP fatigue, abdominal pain, and cholangitis during recovery.Trail Registration::ClinicalTrials.gov, No. NCT03075280.

Objective:To explore the latent categories of outpatient nurses' conflict management styles and analyze their influencing factors.Methods:A total of 408 outpatient nurses from six hospitals of Jiangsu Province were selected as study participants by convenience sampling. Data were collected using a general information questionnaire, the Rahim Organizational Conflict Inventory Scale, the Nurse Burnout Scale, the Caring Ability Inventory Scale and the Wong and Law Emotional Intelligence Scale. Latent profile analysis was used to classify the conflict management styles of outpatient nurses, and logistic regression analysis was applied to identify the influencing factors of different categories.Results:A total of 408 questionnaires were distributed, and 372 valid responses were received, with an effective response rate of 91.18%. Outpatient nurses' conflict management styles were divided into two categories: the "Integration-Concession Group" and the "Dominance-Avoidance Group." Logistic regression analysis showed that being an only child, receiving interpersonal communication training, nurse burnout, humanistic care ability, and emotional intelligence were significant influencing factors of the latent categories of conflict management styles ( P<0.05) . Conclusions:There is heterogeneity in outpatient nurses' conflict management styles. It is recommended that nursing administrators adopt a comprehensive approach, conduct thorough assessments of nurses' general conditions and personality traits, guide nurses toward adopting positive conflict management methods, and enhance their abilities in problem-solving and conflict resolution. This can improve interpersonal relationships and work efficiency in medical settings, stabilize the outpatient nursing workforce, and improve the overall quality of nursing services.

The consumption of ultra-processed foods (UPFs) has surged globally, raising significant public health concerns due to their associations with a range of adverse health outcomes. This review aims to elucidate potential health impacts of UPF intake and underscore the importance of considering diet quality when interpreting study findings. UPF group, as classified by the Nova system based on the extent of industrial processing, contains numerous individual food items with a wide spectrum of nutrient profiles, as well as differential quality as reflected by their potential health effects. The quality of a given food may well misalign with the processing levels so that a UPF food can be nutritious and healthful whereas a non-UPF food can be of low quality and excess intake of which may lead to adverse health consequences. The current review argues that it is critical to focus on the nutritional content and quality of foods and their role within the overall dietary pattern rather than only the level of processing. Further research should dissect health effects of diet quality and food processing, investigate the health impacts of ingredients that render the UPF categorization, understand roles of metabolomics and the gut microbiome in mediating and modulating the health effects of food processing, and consider environmental sustainability in UPF studies. Emphasizing nutrient-dense healthful foods and dietary patterns shall remain the pivotal strategy for promoting overall health and preventing chronic diseases.

The prevention and treatment of cardiovascular diseases have always been a focus of attention in re-lated fields.This paper discusses the application and mechanism of exogenous and endogenous supplementation with β-hy-droxybutyrate in the prevention and treatment of cardiovascular diseases such as myocardial ischemia,myocardial infarc-tion,diabetic cardiomyopathy,hypertension,myocardial inflammation,hypertrophic cardiomyopathy and heart failure.Exogenous β-hydroxybutyrate supplementation can quickly and directly provide substitute energy for the heart and thus prevent and treat heart injury.The comprehensive effect of exogenous β-hydroxybutyrate supplementation is significantly better than that of endogenous β-hydroxybutyrate.Endogenous fatty acid,obtained through a ketogenic diet,needs to be oxidized to β-hydroxybutyrate in vivo for energy supply,which is greatly influenced by glucose and lipid metabolism under the conditions of the basic disease itself.At present,ketogenic diet is not recommended for use in the prevention and treat-ment of myocardial ischemia or myocardial infarction,and in the treatment of diabetic cardiomyopathy or hypertension.

Objective:To explore application value of observed tumor enhancement characteristics by dynamic enhancement magnetic resonance imaging(MRI)in assessing blood supply of small hepatocellular cancer.Methods:The cases data of 80 patients with suspected small hepatocellular cancer who admitted to Yichang Central People's Hospital from January 2019 to January 2023 were retrospectively analyzed.The enhancement characteristics of tumors of all patients were real-timely observed by MRI scanner,which included the relative enhancement degree(RSI),enhancement mode,time-signal intensity curve,etc.The enhanced characteristics of the tumors were recorded,which were combined with a series of variables included disease history,tumor type,tumor size,the number of tumor,liver function status of patients to conduct analysis.The receiver operating characteristics(ROC)curve was adopted to analyze the application value of the observed tumor enhancement characteristics by dynamic enhancement MRI in assessing the status of blood supply of small hepatocellular cancer.Results:There were statistically significant differences in the RSI(F=40.151,P＜0.05),enhancement degree(x2=27.374,P＜0.05),and time-signal intensity curve(x2=20.950,P＜0.05)of dynamic enhanced MRI among different stages of small hepatocellular cancer.The differences in medical history(F=17.844,P＜0.05),tumor type(x2=11.219,P＜0.05),tumor size(x2=14.081,P＜0.05),and the number of tumor(x2=74.310,P＜0.05)among different enhancement degrees of arterial phase were also statistically significant.With the enhancement degree increased,the asymptomatic period increased,and the number of malignant tumors increased,and tumor size increased.The differences in liver function status among different time-signal intensity curves were statistically significant(F=330.182,325.872,216.689,P＜0.05).The area under curve(AUC)value of the ROC of the RSI of observed tumor enhancement characteristics by dynamic enhancement MRI was 0.582(95％CI:0.493-0.670)in assessing blood supply of small hepatocellular cancer.Conclusion:Dynamic enhancement MRI can observe the vascular generation and hemodynamic changes of small hepatocellular cancer,which has a certain application value in assessing blood supply of small hepatocellular cancer,and it can help doctors to choose appropriate treatment plan and assess treatment effect.

Macroautophagy (referred to as autophagy hereafter) is a major intracellular lysosomal degradation pathway that is responsible for the degradation of misfolded/damaged proteins and organelles. Previous studies showed that autophagy protects against acetaminophen (APAP)-induced injury (AILI) via selective removal of damaged mitochondria and APAP protein adducts. The lysosome is a critical organelle sitting at the end stage of autophagy for autophagic degradation via fusion with autophagosomes. In the present study, we showed that transcription factor EB (TFEB), a master transcription factor for lysosomal biogenesis, was impaired by APAP resulting in decreased lysosomal biogenesis in mouse livers. Genetic loss-of and gain-of function of hepatic TFEB exacerbated or protected against AILI, respectively. Mechanistically, overexpression of TFEB increased clearance of APAP protein adducts and mitochondria biogenesis as well as SQSTM1/p62-dependent non-canonical nuclear factor erythroid 2-related factor 2 (NRF2) activation to protect against AILI. We also performed an unbiased cell-based imaging high-throughput chemical screening on TFEB and identified a group of TFEB agonists. Among these agonists, salinomycin, an anticoccidial and antibacterial agent, activated TFEB and protected against AILI in mice. In conclusion, genetic and pharmacological activating TFEB may be a promising approach for protecting against AILI.
