Background: Hepatocellular carcinoma (HCC) is a leading cause of cancer mortality, characterized by poor prognosis due to its high proliferative and invasive potential. Tumor metabolic reprogramming, particularly involving glucose metabolism, is essential for tumor survival. This study investigates the role of the Hippo pathway effector transcriptional co-activator with PDZ-binding motif (TAZ) in regulating gluconeogenesis and promoting tumorigenesis in HCC. Methods: TAZ expression in HCC was analyzed using The Cancer Genome Atlas data and validated in clinical samples and cell lines. TAZ was overexpressed or silenced in HCC cell lines to evaluate its effects on cell proliferation, apoptosis, migration, and invasion. The expression and prognostic relevance of the gluconeogenesis-related genes phosphoenolpyruvate carboxykinase 1 (PCK1) and glucose-6-phosphatase (G6PC) were examined, along with their correlation with TAZ expression. Tumor growth was assessed in nude mice. Interactions between TAZ and the glucocorticoid receptor (GR) were investigated using co-immunoprecipitation, immunofluorescence, and chromatin immunoprecipitation assays. Results: TAZ was significantly upregulated in HCC tissues and cell lines. TAZ overexpression enhanced proliferation, reduced apoptosis, and promoted migration and invasion. In contrast, PCK1 and G6PC were downregulated in HCC and showed a negative correlation with TAZ expression. Conclusion TAZ modulates gluconeogenesis and accelerates tumor growth, whereas its knockdown attenuates tumor progression. TAZ interacts with GR, suppressing its transcriptional activity on gluconeogenic gene promoters.

Executive function(EF) is an advanced cognitive function of the central nervous system, and is closely related to an individual's capacity for daily living and adaptation. Patients with attention deficit hyperactivity disorder (ADHD) typically exhibit significant executive dysfunction. While most existing studies on the executive function of individuals with ADHD are cross-sectional, and little is known about the longitudinal maturation process of related brain structures and functional connectivity patterns. The findings indicate that ADHD patients exhibit differential developmental trajectories in brain structural and functional connectivity compared with typically developing group.Furthermore, there is a lifespan association between abnormal brain network development and ADHD symptoms. This article aims to elucidate the characteristics of executive function deficits in ADHD patients across different developmental stages, examining their relationship with the nervous system’s development from a development perspective.

Objective To investigate the protective effect and mechanism of schisandrin A(SA)on hydrogen peroxide(H2O2)-induced oxidative stress injury in renal tubular epithelial cells(HK-2).Methods HK-2 cells were cultured in vitro and divided into five groups:blank control group,model control group(treated with 600 μmol·L-1 H2O2 for 2 h),low-dose SA group(0.125 μmol·L-1 SA,24 h pretreatment+H2O2),medium-dose SA group(0.5 μmol·L-1 SA,24 h pretreatment+H2 O2),high-dose SA group(0.75 μmol·L-1 SA,24 h pretreatment+H2O2).The cell survival was assessed by CCK-8 assay;apoptosis level was tested by Annexin V-FITC/PI double staining;cell cycle distribution was detected by propidium iodide staining;oxidative markers(ROS,SOD,MDA,GSH,LDH)was determined with commercial kits;and apoptosis-related proteins(Bax,Bcl-2,Caspase-3,Cytochrome C)was evaluated by Western blot.Results Compared with the blank control,the model group reduced in cell viability and increased in apoptosis(P＜0.01),elevated in the ratio of G0/G1-phase cells and decreased in S-phase cells(P＜0.05),decreased in SOD activity and GSH content(P＜0.01),and increased in the levels of ROS,LDH,and MDA levels(P＜0.01).In all SA dose,cell apoptosis reduced(P＜0.01).In medium/high dose groups,the G0/G1-phase arrest reduced(P＜0.05).In high dose group,the S-phase cells ratio increased(P＜0.05).And in medium/high dose groups,ROS(P＜0.01)decreased in a dose-dependent manner.The SOD activity increased non-significantly in all SA groups.In SA medium/high dose groups,the LDH activity decreased in a dose-dependent manner.In all SA groups,GSH increased(P＜0.01)and MDA decreased,both in a dose-dependent manner.The Bax/Bcl-2 ratio significantly decreased(P＜0.05)in all SA groups.The caspase-3 activity decreased in medium/high dose group(P＜0.05);and Cytochrome C reduced in all SA groups(P＜0.05).Conclusion SA protects HK-2 cells against H2O2-induced oxidative injury by modulating oxidative stress,inhibiting apoptosis,and ameliorating cell cycle arrest.

Objective:To develop a rapid assessment scale for healthy aging suitable for the Chinese population.Methods:Based on existing healthy aging assessment scales, national standards, and expert consensus, an initial Healthy Aging Rapid Assessment Scale was drafted through two rounds of expert consultation. A pre-survey was conducted with 3 220 subjects recruited from Guangzhou between July 2023 and July 2024. Items were screened through item analysis and exploratory factor analysis to form the final scale. Reliability and validity of the final scale were validated across five cities: Guangzhou, Dongguan, Shenzhen, Baoding, and Chuxiong.Results:The initial version comprised 36 items, while the finalized scale contained 18 items across three dimensions: metabolic health, mental health, and cognitive health. Test-retest reliability ranged from 0.71 to 0.81 across all study sites. The Spearman-Brown coefficient varied between 0.91-0.96, Cronbach′s α between 0.77-0.83, comparative fit index (CFI) between 0.90-0.98, goodness-of-fit index (GFI) between 0.90-0.99, and root-mean-square error of approximation (RMSEA) between 0.03-0.09. For the three dimensions, reliability and validity metrics demonstrated consistency: Spearman-Brown coefficients 0.87-0.99, Cronbach′s α 0.77-0.83, CFI 0.90-0.98, GFI 0.90-0.99, and RMSEA 0.03-0.09 across four regions.Conclusion:The developed Healthy Aging Rapid Assessment Scale for the Chinese population exhibits robust reliability and validity.

Objective:To explore the value of ultrasound imaging characteristics combined with clinical indicators in assessing the prognosis of patients with pancreatic ductal adenocarcinoma (PDAC).Methods:A retrospective analysis was conducted for patients who underwent pancreatic contrast-enhanced ultrasound (CEUS) from September 2017 to October 2023 at Peking Union Medical College Hospital and were diagnosed with PDAC based on pathological findings. Various parameters were recorded, including CA19-9 levels, tumor size, location, morphologic features, echogenicity, presence of internal cystic components, dilatation of the main pancreatic duct, peripheral vascular invasion, CEUS characteristics, presence or absence of liver metastasis, and treatment methods. In April 2024, patient survival information was obtained through telephone follow-up or review of medical records. Based on the results of the cox regression model analysis, a nomogram model of the risk of death was developed. The receiver operating characteristic (ROC) curves were applied to evaluate the predictive efficacy of the model. The calibration curves were plotted to evaluate the accuracy of the model, and clinical decision curves were used to evaluate the clinical benefit of the model.Results:This study included a total of 207 patients with PDAC. As of April 2024, 71 patients were alive and 136 died, with a median survival time of 14 months (95% CI: 12 -17). Multivariate analysis confirmed that the elevated CA19-9 ( HR=1.689, 95% CI: 1.102-2.588), tumor size >4 cm ( HR=1.641, 95% CI: 1.159-2.322), taller-than-wide shapes ( HR=1.450, 95% CI: 1.019-2.065), incomplete hypo-enhancement ( HR=1.618, 95% CI: 1.100-2.380), and liver metastasis ( HR=1.687, 95% CI: 1.175-2.423) were independent risk factors for survival in patients with PDAC. A nomogram model was further constructed for 6-month, 12-month and 3-year survival of patients with PDAC. The areas under the ROC curve were 0.679, 0.705 and 0.815, respectively. The calibration curves suggested that the model was more accurate, and the clinical decision curves showed that the model had a better clinical benefit. Conclusion:The combined use of ultrasound imaging characteristics and clinical indicators could effectively predict the prognosis of PDAC patients. Specifically, tumor size >4 cm, taller-than-wide shapes, incomplete hypo-enhancement, elevated CA19-9, and the presence of liver metastasis are correlated with poorer survival outcomes. The nomogram model constructed on the basis of these factors can be used to assess the survival of patients with PDAC.

The aim of this study is to establish a rapid,efficient,and sensitive method for detecting the infectious laryngotracheitis virus(ILTV).The DNA of ILTV was extracted and used as a tem-plate to develop a recombinant enzyme-mediated isothermal amplification(RAA)fluorescence de-tection method for ILTV through optimization of conditions,sensitivity analysis,and repeatability assessment.Additionally,the nucleic acids of avian influenza virus(AIV),IBV,and Newcastle dis-ease virus(NDV)were detected to verify the specificity of this method.Finally,this method was applied to analyze 59 clinical samples collected from multiple large-scale chicken farms in Hebei Province,and the results were compared with those obtained from real-time fluorescence quantifi-cation(qPCR)and PCR methods according to national standards.The results showed that the RAA detection method established in this study had a reaction system of 25.0 μL buffer,2.1 μL primer,0.6 μL probe,5.0 μL magnesium acetate,and 5.0 μL template.The reaction temperature was 39 ℃ and the amplification time was within 20 minutes.The sensitivity of this method was 101 copies/μL,and the specificity detection was 100％.Testing of 59 clinical samples showed that 17 were detected positive by both RAA fluorescence and qPCR,and 12 were detected by PCR,and the detection rate of RAA(fluorescence)was consistent with real-time fluorescence quantification and qPCR,which was higher than that of the PCR assay.The research results indicate that the RAA fluorescence method has a short detection time,good specificity and sensitivity,and can be used for rapid detection of ILTV.

Ovarian cancer(OC)is a prevalent malignant gynecological tumor with a high mortality rate.The tumor immune microenvironment,consisting of immune components within the tumor microenvironment,plays a significant role in tumor devel-opment and metastasis.OC is typically categorized as a"cold tumor"due to its immunosuppressive microenvironment,resulting in limited efficacy of immunotherapy for this disease.Specifically,the expression of family with sequence similarity 111 member B(FAM111B)protein has been found to be correlated with the immune microenvironment of various tumors,including its associ-ation with the expression of programmed death ligand-1(PD-L1)in ovarian cancer tissues.This review provides an overview of recent research developments concerning the impact of the FAM111B gene on the immune microenvironment of ovarian cancer.

Objective:To investigate the status of leisure crafting and post competence and their correlation among anesthesia specialist nurses.Methods:A convenience sampling method was used to conducted a questionnaire survey on 280 anesthesia specialist nurses at grade A tertiary hospitals in 19 provinces of China. Data were collected using a general information questionnaire, the Chinese version of Leisure Crafting Scale, and the Post Competency Scale for Anesthesia Specialist Nurses. SPSS 24.0 was used for t test and one-way analysis of variance. A Pearson correlation analysis was used to assess relationships between variables. Results:The total score of leisure crafting was (30.41±6.69) and the average score was (3.38±0.74). The total score of post competency was (141.76±21.76) and the average score was (3.73±0.57). A positive correlation was observed between leisure crafting and post competency ( r=0.215, P<0.01). Conclusions:Managers should encourage anesthesia specialist nurses to actively engage in leisure crafting and provide diverse opportunities for leisure crafting to improve their post competence and ultimately the quality of anesthesia nursing.

Stiff person syndrome (SPS) is a rare neuro-immune disorder characterized by exaggerated startle responses and muscle spasms in response to minor stimuli. SPS is often misdiagnosed as panic disorder or agoraphobia. This paper reported a case of a patient with SPS presenting symptoms similar to panic attack. The patient had been misdiagnosed as dystonia, anxiety disorder and panic attack. The patient was finally correctly diagnosed through multiple disciplinary team discussions. This study integrates a comprehensive understanding of symptomatology and patient-reported experiences with targeted neurological evaluations and supplementary diagnostic tools to improve the accuracy of etiological diagnoses. This study aims to enhance the ability of psychiatrists to recognize somatic diseases presenting with psychiatric symptoms and to improve clinical diagnostic and treatment levels.
