Depression has emerged as a concerning factor in colon cancer progression and treatment, yet its underlying mechanisms and therapeutic targets remain poorly defined. This study aimed to elucidate how depression affects colon cancer progression and chemotherapeutic response, and to explore potential molecular targets and therapeutic interventions involving the traditional Chinese medicine formula Sinisan (SNS) and its bioactive component Quercetin. A mouse model combining depression and colon cancer was established to evaluate behavioral alterations, tumor progression, and pathological features. RNA sequencing was performed to screen the differentially expressed genes. The effects of corticosterone (CORT) on proliferation, colony formation, migration, and GSTM2 expression were examined in HCT116 cells, followed by functional validation through GSTM2 overexpression and inhibition assays. Molecular docking, molecular dynamics simulations, and surface plasmon resonance (SPR) were used to validate the binding of Quercetin to GSTM2. The therapeutic efficacy of SNS and Quercetin was assessed with respect to depressive symptoms, serum BDNF levels, NLRP3 inflammasome activity, and the potency of 5-fluorouracil (5-FU) chemotherapy. Mice with depression and colon cancer exhibited aggravated depressive behaviors and accelerated tumor progression. RNA-sequencing and network pharmacology analyses identified GSTM2 as a promising candidate target in colon cancer treatment, which was markedly down-regulated in the DP-CC group. CORT enhanced proliferation, colony formation, and migration of HCT116 cells while simultaneously suppressing GSTM2 expression. Conversely, GSTM2 levels negatively correlated with cell proliferation, colony formation, and chemoresistance in HCT116 cells. Treatment with SNS alleviated depressive symptoms, elevated serum BDNF, reduced NLRP3 inflammasome activity, and potentiated the efficacy of 5-FU chemotherapy. Quercetin, a bioactive component of SNS, bound to GSTM2 through hydrogen-bond and van-der-Waals interactions, up-regulated GSTM2 expression, and mitigated CORT-induced proliferation, colony formation, and chemoresistance. Our findings suggest that depression promotes colon-cancer progression by down-regulating GSTM2, whereas SNS restores GSTM2 expression and enhances chemotherapeutic response. Show less

Arterial thrombectomy (AT) is a cornerstone in the treatment of acute ischemic stroke (AIS) due to large vessel occlusion. However, the optimal therapeutic time window and the best management strategy for patients presenting beyond the conventional 4.5-hour timeframe remain areas of active investigation and debate. This retrospective cohort study aimed to analyze the effect of timing of AT on recovery in AIS. We retrospectively analyzed 117 AIS patients admitted between January 2021 and January 2023. Participants were categorized into 3 groups: early AT (onset-to-AT < 4.5 hours), late AT (onset-to-AT ≥ 4.5 hours), and late AT + intravenous thrombolysis (IT). Outcomes compared included clinical efficacy, National Institutes of Health Stroke Scale (NIHSS) scores, serum levels of neurotrophic factors, brain-derived neurotrophic factor, vascular endothelial growth factor, residual stenosis, vessel reocclusion, 3-month mortality, and 1-month complications. The total effective rate was higher in the early AT and late AT + IT groups than in the late AT group. Pretreatment NIHSS scores and serum neurological marker levels were comparable across all groups. After treatment, the early AT and late AT + IT groups showed significantly lower NIHSS scores, higher serum levels of neurological markers, and improved treatment efficiency compared to the late AT group. Prognosis-related markers also indicated better outcomes in these 2 groups. Additionally, complications such as mucocutaneous ecchymosis, gastrointestinal bleeding, and intracranial bleeding were significantly reduced in the early AT and late AT + IT groups. AT within 4.5 hours of stroke onset improves efficacy, reduces neurological injury, and decreases complications. For patients presenting beyond 4.5 hours, combining AT with IT achieves comparable therapeutic benefits. Show less

Elevated lipoprotein(a) [Lp(a)] is a genetically determined, causal risk factor for atherosclerotic cardiovascular disease, but effective therapies remain limited. Proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors are primarily used to lower low-density lipoprotein cholesterol (LDL-C), yet their effects on Lp(a) have been inconsistently reported. This umbrella review synthesizes meta-analytic evidence on PCSK9 inhibitors and Lp(a). We systematically searched PubMed, Embase, Web of Science, and Cochrane Library through April 2025 for meta-analyses of randomized controlled trials (RCTs) comparing PCSK9 inhibitors (alirocumab, evolocumab, inclisiran) with placebo or standard therapy. The primary outcome was mean percentage change in Lp(a). Methodological quality was assessed using the Assessment of Multiple Systematic Reviews 2 (AMSTAR-2), and evidence certainty was graded with the Grading of Recommendations Assessment, Development, and Evaluation (GRADE). Overlap of primary trials was quantified using the Corrected Covered Area (CCA), and sensitivity analyses were performed to account for overlapping evidence. Twenty-one meta-analyses (116 RCTs; 231,796 participants) were included. The PCSK9 inhibitors consistently reduced Lp(a): evolocumab (29.68-46.68%; high certainty), alirocumab (18.55-26.46%; high certainty), and inclisiran (18.00%; high certainty). Higher biweekly doses yielded larger decreases (e.g., alirocumab 150 mg: 24.6%; evolocumab 140 mg: 26.8%, high certainty). Reductions were dose-dependent and broadly consistent across populations, comparators, follow-up durations, and baseline Lp(a). The Lp(a) reductions correlated modestly with LDL-C (β = 0.28; 95% CI 0.07-0.49) and apolipoprotein B (apoB) (β = 0.33; 95% CI 0.03-0.63). Concomitant reductions in LDL-C, apoB, and major adverse cardiovascular events were supported by high and moderate certainty evidence. Safety was favorable, with injection-site reactions being the most common adverse event. Sensitivity analyses confirmed robustness of findings after accounting for overlapping trials. The PCSK9 inhibitors, particularly evolocumab 140 mg every 2 weeks, significantly lower Lp(a) alongside LDL-C and apoB. These findings highlight the consistent Lp(a)-lowering effect of PCSK9 inhibitors. However, the observed cardiovascular benefits are largely attributable to concomitant LDL-C reduction, and the incremental contribution of Lp(a) lowering remains uncertain. Confirmation from outcome trials specifically designed to target Lp(a) is required. PROSPERO CRD420251048597. Show less

Metabolic dysfunction-associated steatotic liver disease (MASLD) is characterized by hepatic steatosis with cardiometabolic disorders. Due to the complicated pathophysiological processes, current therapeutic strategies for MASLD remain limited. Previous studies revealed that miR-320 was a regulator of systemic lipid metabolism with multi-targets. However, whether treatments against miR-320 would be benefit to MASLD was unclear. Mice with MASLD were induced by high-fat diet (HFD) treatment. Tough Decoy or sponge against miR-320 was delivered by recombinant adeno-associated virus (serotype 8) vectors in vivo. Hepatic steatosis and plasma lipids were assessed by histopathology, biochemical assays and LC-MS. Moreover, LC-MS, Western blotting, real-time PCR, immunofluorescence and luciferase reporter were performed to investigate the underlying mechanisms. Knockdown of miR-320 attenuated HFD-induced MASLD by alleviating hepatic lipid accumulation and hyperlipidemia. Mechanistically, palmitic acid (PA) combined with oleic acid (OA) treatment promoted the translocation of miR-320 from the cytoplasm into the nucleus of hepatocytes. Especially, increased nuclear miR-320 activated the transcription of APOE by targeting its promoter, which in turn aggravated triglyceride accumulation and secretion in hepatocytes. Our study revealed that treatments against miR-320 attenuated hepatic steatosis and hyperlipidemia simultaneously, which might be a potential strategy of MASLD. Show less

This study aims to investigate the effects of mulberry anthocyanin (MA) in high-fat and high-cholesterol (HFHC) diet-fed ApoE-/- mice. ApoE-/- mice were randomly divided into control (ACON), mulberry fruit anthocyanin extract (MFAE), cyanidin-3-glucoside (C3G) group 1 (C3GT), and C3G group 2 (C3GP). After 7 weeks of HFHC diet feeding and following 2-3 weeks of treatment, samples were collected and analyzed. The C3GT group significantly decreased low-density lipoprotein (7.3 ± 1.5 mmol/L) and interleukin-1β (355.4 ± 41.7 pg./mL) levels. Moreover, the MFAE (636.3 ± 90.7 pg./mL), C3GT (611.5 ± 65.4 pg./mL), and C3GP (757.5 ± 47.6 pg./mL) significantly increased glutathione peroxidase (GSH-PX) levels compared with those in the ACON group. The MA treatments significantly increased the number of MA treatment may attenuate AS-associated risk factors by decreasing inflammatory factor-related gut microbial genera. The mechanism may be related to regulating liver glutamine, ATP, and related metabolic pathways. Show less

Atherosclerosis is fundamentally a pathology of unresolved inflammation perpetuated by the collapse of Regulatory T cell (Treg)-mediated tolerance. Emerging evidence indicates that Treg functional integrity is intrinsically dictated by mitochondrial fatty acid oxidation (FAO), a metabolic checkpoint often compromised under systemic metabolic stress. Current lipid-lowering therapies, such as statins, often fall short in correcting this maladaptive immunometabolic defect and may introduce collateral metabolic perturbations. This study aimed to elucidate the immunometabolic therapeutic mechanism of Dingxin Recipe III (DXR III) in ameliorating atherosclerosis. We employed an integrated systems pharmacology strategy-combining serum pharmacochemistry, multi-omics profiling, and extensive high-dimensional flow cytometry-to elucidate the therapeutic mechanism of DXR III, a traditional Chinese herbal formula in an in vivo study. ApoE DXR III treatment effectively attenuating atherosclerotic progression. Serum pharmacochemistry identified 254 prototypical absorbed constituents, including Tanshinone I (a potential Peroxisome Proliferator-Activated Receptor Gamma agonist), as bioactive candidates. Multi-omics analysis revealed that DXR III modulated the metabolic environment, coinciding with restored FAO flux. This shift was associated with a favorable metabolic niche characterized by increased FAO substrates, which correlated with the rescue of Treg differentiation and phenotypic stability. Specifically, DXR III facilitated the redistribution of Tregs from the spleen to plaque sites and significantly inhibited their trans-differentiation into Th1-like or Th17-like phenotypes. Conversely, Simvastatin treatment, despite lowering lipids, resulted in peripheral Th17 accumulation and failed to alleviate hyperglycemia. In contrast, DXR III maintained Th17 homeostasis-abolishing the pathogenic non-classical Th17 subset-and exerted dual-regulatory effects on both lipid and glucose metabolism. DXR III ameliorates atherosclerosis, a process closely associated with the modulation of the FAO metabolic checkpoint to correct the immune imbalance driving plaque progression. By rescuing the Treg differentiation, functional integrity, and phenotypic fidelity while avoiding the immunological trade-offs associated with Th1/Th17, DXR III represents a promising candidate for comprehensive cardiovascular protection.

Abdominal aortic aneurysm (AAA) is a serious disease with no effective pharmacological therapy. Although inflammation is recognized as a key regulator of AAA, targeting inflammatory pathways once the disease is established does not improve outcomes. Understanding the earliest molecular indicators could clarify precise biological targets and prognostic markers for AAA. Using ApoE-deficient mice, we performed RNA-Seq on suprarenal abdominal aortas (SRAs) from Ang II- and saline-treated mice 24 h after infusion. We further developed a unique model of hyperlipidemic mice in which the expression of the inhibitor of nuclear factor kappa B kinase subunit beta (IKKβ) can be conditionally suppressed in vascular smooth muscle cells (VSMCs). RNA-Seq data revealed early IKKβ-dependent cellular anabolic processes in SRAs, including activation of the mammalian target of rapamycin complex 1 (mTORC1) pathway. Furthermore, deletion of the Show less

The APOE4 is a well-established and significant genetic risk factor associated with the accumulation of β-amyloid (Aβ) plaques and hyperphosphorylated tau (p-tau) in the pathogenesis of Alzheimer's disease (AD). Our previous research has implicated circular RNA FoxO3 (circ-FoxO3) in the clearance of aggregated proteins in ischemic stroke. However, the role of circ-FoxO3 in the accumulation of abnormal proteins during AD development remains unclear. In this study, we demonstrate that circ-FoxO3 mitigates APOE4-driven neurotoxic protein aggregation by enhancing FoxO3-mediated autophagy. Specifically, transgenic mice expressing human APOE4 exhibited elevated levels of p-tau and Aβ, and these pathological alterations were significantly ameliorated by circ-FoxO3. Mechanistically, we found that circ-FoxO3 upregulates its host gene FoxO3, leading to activation of autophagy and subsequent clearance of neurotoxic protein aggregates. The findings highlight a critical role for circ-FoxO3 in counteracting APOE4-induced brain damage and suggest its potential as a therapeutic target for mitigating APOE4-related neuropathology.

Abdominal aortic aneurysm (AAA) is a life-threatening condition with limited pharmacological therapies. The pathological progression of AAA is closely attributed to the phenotypic switching of vascular smooth muscle cells (VSMCs). NFS1 is the rate-limiting enzyme for the synthesis of iron-sulfur proteins, and the roles of NFS1 in AAA initiation and development have not been explored.

Atherosclerosis (AS) serves as the pathological foundation for numerous cardiovascular and cerebrovascular diseases and is highly comorbid with depression. The mechanisms underlying this co-morbidity are exceptionally complex, posing significant challenges to effective clinical treatment. Consequently, our study aims to explore the potential biomarkers and mechanisms involved in developing atherosclerosis co-depression disease. We performed differential expression analysis, protein-protein interaction analysis, Gene Ontology (GO) function enrichment analysis, and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis on co-differentiated genes using AS and depression-related datasets from the GEO database. Potential biomarkers were identified through ROC curve analysis. To evaluate the effectiveness of the model, we established an animal model of AS comorbid with depressive disorder and performed a series of assessments, including the sugar-water preference test, open field test, tail suspension test, lipid profile analysis, and pathological examination of aortic sections. Additionally, RNA sequencing analysis of brain tissue, Golgi staining, and detection of synaptic function-related proteins were performed in AS comorbid depressed mice. Finally, in vitro cellular experiments were conducted to further validate the molecular targets and underlying mechanisms. We identified 968 differentially expressed genes associated with AS and 472 differentially expressed genes associated with depression, with 30 genes co-differentially expressed. Protein-protein interaction (PPI) analysis revealed that CCR5, CCR2, NPY, and OPRM1 were strongly associated with AS co-depression, while ROC analysis indicated that Shank2, MDGA2, and S100B were diagnostic markers for AS with depression. Differentially expressed genes were closely associated with the chemokine signaling pathway, neuroactive ligand-receptor interaction, cytokine-cytokine receptor interaction, and taste transduction. Animal studies demonstrated that ApoE Our study identified seven candidate AS co-depression biomarkers and verified that inflammation-induced damage to synaptic plastic rows is an important mechanism of AS co-depression, providing new insights into the diagnosis and treatment of AS co-depression disorders.

Multiple sclerosis (MS) is a chronic neurodegenerative disorder for which dysregulated ferroptosis and necroptosis have demonstrated pathological associations but these lack causal validation in disease susceptibility. This study employed proteome-wide Mendelian randomization (MR) to investigate causal links between ferroptosis/necroptosis pathways, their upstream regulators, immune interactions, and MS risk. Transcriptomic validation utilized bulk RNA-seq and single-cell RNA-seq data. MR identified IFNA4 (OR = 0.24) and TNFAIP3 (OR = 2.0) as key causal ferroptosis/necroptosis-related proteins for MS risk. Analysis revealed 15 upstream regulators significantly associated with MS (FDR < 0.05; e.g., GZMA, CXCL3, APOE, CFB, CA6, KIR2DL2/3). Transcriptomic validation consistently identified ceruloplasmin (CP) as upregulated in MS microglia and lesions. Mediation analyses established two complete causal pathways: an IFNA4-mediated pathway wherein five upstream immune regulators (KIR2DL2, KIR2DL3, CFB, GZMA, and CA6) influence MS susceptibility through IFNA4 regulation, with all component effects statistically significant; and an APOE-driven pathway operating via TNFAIP3, demonstrating significant total effects and near-significant mediator-outcome effects on MS risk. While 59 immune traits were MS-associated, only TNFAIP3 showed a suggestive association with CD27⁺ memory B cells. This study establishes ferroptosis/necroptosis pathways as causal drivers of MS susceptibility, highlighting TNFAIP3, IFNA4, CP, and APOE as therapeutically actionable targets. Show less

Previous studies indicate associations between inflammatory cytokines and glioma, meningioma, and astrocytoma. We conducted two-sample Mendelian randomization with genetic data for tumors from FinnGen R10 and cytokine data from GWAS. Primary analysis used inverse variance weighting, supplemented by sensitivity analyses including weighted median, simple mode, weighted mode, and MR-Egger. For glioma, TNF-related apoptosis-inducing ligand (TRAIL) was a risk factor, while Fibroblast growth factor 21 (FGF21) was protective. For meningioma, Axin-1 and Matrix metalloproteinase-1 were risk factors, whereas Fms-related tyrosine kinase 3 ligand was protective. For astrocytoma, risk factors included Eotaxin, Macrophage colony-stimulating factor 1, and Interleukin-8; protective factors were T-cell surface glycoprotein CD5 and Tumor necrosis factor ligand superfamily member 12. This Mendelian randomization study identified specific inflammatory cytokines associated with these tumors, providing direction for future mechanistic research. Show less

Hepatocellular carcinoma (HCC) is a major malignancy with rising global incidence and mortality. Clinical treatment is limited by molecular heterogeneity and drug resistance. In recent years, endocrine-disrupting chemicals (EDCs) have attracted attention as emerging risk factors, but systematic pathogenic evidence for their roles in HCC initiation and progression remains insufficient. First, we predicted potential targets of EDCs using SwissTargetPrediction, STITCH, and ChEMBL, and intersected them with differentially expressed genes and key module genes from WGCNA in the GEO database to screen candidate key genes. Second, based on these candidates, we constructed diagnostic models using 14 machine-learning algorithms and evaluated feature importance via the SHAP framework to identify key biomarkers and their functional contributions. Molecular docking and molecular dynamics simulations were used to validate interaction mechanisms between EDCs and key target proteins. We then built a multivariable Cox proportional hazards model in the TCGA-LIHC cohort and performed stratified survival analysis, somatic mutation profiling, and immune evasion characterization. Subsequently, we evaluated the tumor immune microenvironment using CIBERSORT and ssGSEA, and integrated single-cell transcriptomic data to resolve cell-subtype heterogeneity, target expression distributions, and cell-cell communication. Meanwhile, we integrated the GDSC drug-sensitivity database to evaluate associations between risk scores and drug response, and conducted pan-cancer analyses to examine cross-cancer applicability. We identified 18 genes jointly associated with EDCs and HCC, significantly enriched in AMPK, p53, and FoxO signaling pathways and cell cycle-related pathways. Among models built with 14 machine-learning algorithms, CatBoost showed the best discriminative performance and identified CCNB2 and AKR1C3 as core driver genes. Docking and dynamics simulations indicated strong binding affinities and stable binding conformations between EDCs and target proteins including CCNB1 (-8.9 kcal/mol), AKR1C3 (-8.4 kcal/mol), and FADS1 (-8.5 kcal/mol). A multivariable Cox risk model based on nine key genes served as an independent prognostic predictor for HCC (HR = 1.746, 95% CI: 1.477-2.064, P < 0.001). The nomogram achieved AUCs of 0.836, 0.810, and 0.788 at 1, 3, and 5 years, respectively, indicating good predictive performance. The high-risk group was significantly associated with high tumor mutational burden (TMB), TP53 mutations, and low immune evasion scores. Regarding the tumor immune microenvironment, CIBERSORT and ssGSEA analyses showed marked enrichment of Tregs and M0 macrophages, while most effector immune cells and functions were suppressed. Single-cell transcriptomics further showed enrichment of endothelial cells, fibroblasts, hepatocytes, and macrophages in HCC tissues, with notable reductions in T cells, B cells, NK cells, and neutrophils, indicating an immunosuppressive microenvironment with stromal remodeling. Cell-cell communication analysis indicated that the MIF-CD74 receptor axis is central in immune-cell interactions. Drug-sensitivity analysis suggested that the high-risk group was more sensitive to GDC0810, BPD-00008900, and Fulvestrant, indicating potential beneficiary populations. Pan-cancer analysis showed that the risk model also had diagnostic and prognostic value in LUAD, KIRP, KIRC, and KICH, suggesting cross-cancer generalizability. This study systematically reveals that EDCs promote HCC initiation and progression by perturbing cell cycle, metabolic, and immune homeostasis through multi-target, multi-pathway mechanisms. The nine-gene risk model demonstrates superior performance in HCC diagnosis and prognosis and shows potential clinical translational value in drug-sensitivity prediction and pan-cancer analyses. This work provides a new perspective at the intersection of environmental toxicology and precision oncology and informs individualized therapeutic strategies. Show less

Interleukin-27 (IL-27) in the pleural fluid has gained significant attention as a diagnostic biomarker for tuberculous pleural effusion (TPE); however, considerable variability exists across available studies. This systematic review and meta-analysis aimed to determine the diagnostic accuracy of IL-27 in identifying TPE. In addition, we also compared the diagnostic accuracy of IL-27 and adenosine deaminase (ADA) with a head-to-head meta-analysis. We searched the PubMed and Web of Science databases to identify diagnostic test accuracy studies evaluating the accuracy of IL-27 for diagnosing TPE. The last search date was September 2025. We extracted data from the eligible studies and constructed a two-by-two table with true positives (TP), false positives (FP), true negatives (FN), and false negatives (FN). The QUADAS-2 tool was used to assess the quality of eligible studies. A bivariate model was applied to pool sensitivity and specificity, and a summary receiver operating characteristic (sROC) curve with the area under the curve (AUC) was generated to estimate the overall diagnostic accuracy of IL-27 and ADA. A Deeks funnel plot asymmetry test was used to evaluate publication bias. Nine studies encompassing ten cohorts were included, involving 1573 patients (429 with TPE and 1144 with non-TPE). The reported AUCs for IL-27 ranged from approximately 0.73 to 0.99 across eligible studies. The pooled sensitivity and specificity were 0.94 (95% CI, 0.83-0.98) and 0.96 (95% CI, 0.89-0.98), respectively. The AUC for sROC was 0.99 (95% CI, 0.97-0.99). The pooled positive likelihood ratio was 21.97 (95% CI, 7.95-60.69), the negative likelihood ratio was 0.07 (95% CI, 0.02-0.18), and the diagnostic odds ratio (DOR) was 329 (95% CI, 72-1506). Significant heterogeneity was observed in both sensitivity (I IL-27 is a promising diagnostic marker for TPE, and its diagnostic accuracy is comparable to that of ADA. IL-27 should be used as a complementary diagnostic marker to ADA for TPE. Show less

Obesity results from the interaction of polygenic susceptibility and environmental factors. Given this complex etiology, physical activity (PA) remains a cornerstone of cost-effective intervention strategies. This longitudinal natural experiment investigated how PA modifies the effects of genetic predisposition on obesity in Chinese youth. We conducted a 4-year natural experiment leveraging curriculum-driven PA disparities in a specialized arts school (n = 591), creating distinct high-PA (HPA) and low-PA (LPA) exposure groups. Weighted genetic risk scores (WGRSs) were calculated from 13 Asian-derived obesity-related single-nucleotide polymorphisms. Annual anthropometric, metabolic, and lifestyle data were analyzed using generalized linear mixed models to assess gene-PA interactions on obesity. The WGRS predicted baseline obesity measures, with each unit increase associated with a 0.21-kg/m² higher BMI. Over the natural experiment period, BMI increases in the HPA group were smaller than in the LPA group. After adjusting for age, sex, ethnicity, and dietary factors, significant WGRS-PA interactions were observed for BMI trajectories. Participants with higher genetic risk for obesity experienced greater BMI and weight reduction benefits from sustained long-term PA. In summary, the present study identified a significant interaction effect between PA levels and WGRS in modifying BMI trajectories. Genetic susceptibility significantly modifies the protective effects of long-term PA on BMI progression in this cohort of Chinese youth. Show less

Nurses' voice behavior is critical for patient safety and organizational improvement. However, its manifestation is not uniform among nurses. This study aimed to identify latent profiles of nurses' voice behavior using Latent Profile Analysis (LPA) to understand this heterogeneity and explore its influencing factors, with a specific focus on differences across work motivation dimensions (rooted in Self-Determination Theory, SDT). A multicenter cross-sectional design was adopted. Data from 701 clinical nurses across six hospitals in Guangxi Province were analyzed: LPA identified four distinct profiles, and Multinomial Logistic Regression was used to examine predictors. Work motivation was measured by the Multidimensional Work Motivation Scale (MWMS), and voice behavior by the Voice Behavior Scale (VBS). LPA identified four distinct profiles (Conservative, 5.42%; Balanced Risk-Taker, 26.39%; Transitional, 34.38%; Challenging, 33.8%), and Multinomial Logistic Regression was used to examine predictors. Work motivation was measured by the Multidimensional Work Motivation Scale (MWMS), and voice behavior by the Voice Behavior Scale (VBS). Results showed autonomous motivation (e.g., intrinsic drive) strongly predicted active voice behavior, while amotivation predicted conservative profiles. Nurses exhibited high work motivation (MWMS: 93.02 ± 21.09) and moderately high voice behavior (VBS: 39.27 ± 8.736). The research found that nurses exhibited high work motivation and moderately high voice behavior, with autonomous motivation being a pivotal predictor. Differentiated strategies targeting intrinsic motivation enhancement are critical for fostering nursing innovation and improving care quality. Show less

Previous studies have indicated that Kinesiophobia is associated with adherence to exercise rehabilitation. Given the multifaceted impact of Kinesiophobia and the complex diversity of individual characteristics, existing research struggles to identify the distinct features of Kinesiophobia. Latent Profile Analysis (LPA) identifies individuals’ latent traits based on their response patterns to observable measures, grouping individuals with similar symptom profiles into different categories, thereby better distinguishing differences among individuals. However, there is currently a lack of research on the kinesiophobia in the out-of-hospital early rehabilitation phase after Percutaneous coronary intervention (PCI) in patients with coronary heart disease (CHD). Therefore, the aim of this study is to investigate kinesiophobia in the out-of-hospital early rehabilitation phase after Percutaneous coronary intervention (PCI) in patients with coronary heart disease (CHD), classify it based on latent profile analysis, and explore the related factors of Kinesiophobia in CHD patients across different categories. This study selected coronary heart disease patients who were in the early outpatient rehabilitation stage after receiving PCI treatment at a tertiary hospital as the survey subjects. Latent Profile Analysis (LPA) was employed to fit potential classes of kinesiophobia among these patients. Chi-square tests, Kruskal-Wallis tests, and multinomial logistic regression were utilized to explore the factors influencing different kinesiophobia profiles in these patients. A total of 293 survey subjects were included, the age of the 293 patients was 62.31 ± 11.49 years, Males represent 77% of the total population. The results of potential profile analysis revealed that kinesiophobia in the out-of-hospital early rehabilitation phase of CHD in PCI-treated patients could be divided into three potential categories: the low kinesiophobia-exercise avoidance group (52.1%), the medium kinesiophobia-danger perception group (41.6%), and the high kinesiophobia-dysfunction group (6.3%). The logistic regression analysis results revealed that age, mode of residence, chronic comorbidities, polypharmacy, and debilitation were influential factors for different categories of kinesiophobia in the out-of-hospital early rehabilitation phase of CHD patients undergoing PCI. There is obvious group heterogeneity in kinesiophobia in the out-of-hospital early rehabilitation phaseof CHD patients undergoing PCI, and healthcare professionals should carry out individualized intervention Strategies to reduce the degree of kinesiophobia in patients on the basis of the characteristics and influencing factors of different categories.

Physical activity (PA) is known to enhance brain health; however, prior research has predominantly concentrated on the total volume of PA, often overlooking the frequency of daily PA on an hourly basis. This prospective cohort study examined 69,393 middle-aged and older adults, utilizing wrist-worn accelerometer data to assess PA. A novel PA frequency score was developed, which integrated light PA (LPA) and moderate-to-vigorous PA (MVPA) across 18 hourly segments (6:00 AM-12:00 AM). Participants were categorized into Inactive, Active, and Very Active groups. After adjusting for potential confounders, it was observed that individuals in the Active and Very Active groups exhibited a reduced risk of developing brain disorders such as dementia, anxiety, depression, migraine, Parkinson's disease, and stroke over a median follow-up period of 7.41 years. Magnetic Resonance Imaging (MRI) findings demonstrated that each unit increase in the PA frequency score correlated with a 51.55 mm Show less

Occupational stress in nursing is a critical issue that can have significant implications for both workforce stability and personal health. This study aimed to identify subgroups of occupational stress among Chinese female clinical nurses using latent profile analysis, compare sociodemographic differences across these subgroups, and examine their associations with premenstrual syndrome (PMS). A cross-sectional study was conducted among female nurses in tertiary hospitals in Huai'an City, Jiangsu Province, China, from November to December 2023. We recruited participants via convenience sampling, and 400 valid questionnaires were collected. Data were collected using a researcher-developed general information questionnaire, the standardized Chinese Nurses Stressor Scale (35 items), and the Premenstrual Syndrome Scale. Latent profile analysis (LPA) was performed with Mplus 8.0 to identify occupational stress subtypes. Sociodemographic predictors of these subtypes were explored using chi-square tests and multivariate logistic regression in SPSS 25.0. The association between stress subtypes and PMS symptoms was assessed using ANOVA. A Three clinical female nurse occupational stress subtypes were identified: overall low-stress (38.3%, This study identified significant heterogeneity in occupational stress among clinical female nurses, categorized into three distinct subtypes differing in stress levels and demographic characteristics. These findings highlight the importance of considering individual differences when developing interventions to address occupational stress. The study advocates for the implementation of intervention strategies targeting different types of stress in nursing education and organizational reform to better support nurses in fulfilling their responsibilities.

Calcific aortic valve disease (CAVD) is a cardiovascular disease closely associated with aging. The role of lipoprotein(a) [Lp(a)] has attracted considerable attention in recent years. However, limited research has simultaneously explored the relationships between Lp(a), age, and CAVD. This study sought to assess the relationship linking Lp(a), time-weighted Lp(a), and CAVD. A total of 5,156 inpatients with comprehensive clinical data were recruited for this study. The associations of Lp(a) and time-weighted Lp(a) with CAVD were examined via multivariate logistic regression analysis, alongside the application of restricted cubic spline analysis. The diagnostic utility of Lp(a) and time-weighted Lp(a) for CAVD was assessed by constructing receiver operating characteristic (ROC) curves. CAVD prevalence rose with age, whereas the rate of increase diminished with advancing age. The average Lp(a) level in the young populations with CAVD was more than twice that in the No-CAVD group, particularly among those aged 55 years or younger. The prevalence of CAVD in non-elderly populations was markedly 2–4 fold greater in the higher Lp(a) group (> 30 mg/dL) than in the lower Lp(a) group (≤ 30 mg/dL). Multivariate adjusted odds ratios ‌(ORs) for CAVD increased with advancing Lp(a) or age. Time-weighted Lp(a), which takes into account both age and Lp(a), was more strongly linked to elevated CAVD risk than Lp(a) alone. Time-weighted Lp(a) enhanced the diagnostic value of CAVD, improving both sensitivity and specificity. The risk of CAVD is strongly associated with both age and elevated Lp(a) levels. Time-weighted Lp(a), which integrates these factors, serves as a superior indicator that better captures cumulative long-term Lp(a) variation and yields stronger CAVD risk stratification.

Preschool children's activity patterns differ between weekdays and weekends. Weekdays are constrained by structured educational activities and parental commitments, which limit flexibility, while weekends provide opportunities for extra sleep (SLP), physical activity (PA), and reduced sedentary behavior (SB). This study aims to estimate optimal activity durations for both weekdays and weekends, based on the development of executive function (EF), fundamental movement skills (FMS), and physical fitness (PF) in preschool children. A total of 289 preschool children aged 3-6 years from four kindergartens in Zhejiang Province participated. PA and SLP were objectively measured using accelerometers and the Children's Sleep Quality Questionnaire. EF, which includes working memory, inhibitory control, and cognitive flexibility, was measured using the Early Years Toolbox (EYT). FMS were assessed using the test of gross motor development-3rd edition (TGMD-3), and PF was evaluated according to the National Physical Fitness Measurement Manual (Preschool Children Section). Compositional data regression models were applied to examine the relationship between 24-h movement behaviors and health outcomes on weekdays and weekends. Optimal time-use compositions for each outcome were estimated, and 3D quaternary plots were generated to define the Goldilocks Day at the center of the overlapping regions. 24-h movement behaviors were significantly correlated with EF (weekdays: F = 5.4, This study provides recommendations for time allocation on weekdays and weekends to support the healthy development of preschool children.

Organic room-temperature phosphorescence (RTP) materials have attracted significant interest due to their potential in optoelectronics and anti-counterfeiting. However, achieving multicolor-tunable and long-lived RTP with simple, low-cost systems remains challenging. Herein, a facile host-guest doping strategy is developed to realize efficient and color-tunable RTP by embedding butterfly-shaped triphenylamine-based guest molecules (TPA, DBD, and DBDBD) into various host matrices (e.g., TPP, BPP, or CA). The doped crystals exhibit distinct afterglow colors (green to yellow) and prolonged long-persistent luminescence (LPL) (from 1 to 6 s of afterglow time) and phosphorescence lifetimes up to 763.33 ms, governed by host-guest energy transfer and intersystem crossing enhancement. Density functional theory (DFT) calculations reveal that the guest's electron-donating ability and the host's heavy-atom effect (e.g., P in TPP) synergistically promote charge separation and suppress non-radiative decay. Notably, DBDBD:TPP shows the longest LPL (6 s of afterglow time) due to optimal energy level alignment and strong intermolecular interactions. By leveraging the time- and color-dependent afterglow, applications in multilevel information encryption and anti-counterfeiting are demonstrated, where encrypted messages are dynamically revealed under UV excitation. This work provides a simple yet versatile approach to designing low-cost, multicolor RTP materials for advanced photonic applications. Show less

Previous experiments have demonstrated that BGM0504, a GLP-1R/GIPR dual agonist drug by molecular dynamics-guided optimization, had enhanced agonistic activity compared to tirzepatide. This study aims to investigate its safety, tolerability, pharmacokinetics (PK) and pharmacodynamics (PD) in Chinese healthy volunteers. A randomized, double-blind, placebo-controlled and dose-escalation Phase I study was conducted as follows: a single dose (2.5 mg) and once-weekly administration for 2 weeks to reach target doses (5, 10 and 15 mg) by titration. A total of 40 volunteers received at least one dose of BGM0504 or placebo. The PK profile of BGM0504 was investigated over a wide dose range and supported once-weekly administration. It was observed that C BGM0504 was generally safe and well tolerated with favourable PK profile and potential role in weight loss was also confirmed. These findings support subsequent development of BGM0504 for type 2 diabetes mellitus (T2DM) and obesity. Show less

Angiopoietin-like protein 8 (ANGPTL8) forms complexes with ANGPTL3 and ANGPTL4 to regulate lipoprotein lipase (LPL) activity, and decreased LPL activity is an established cardiovascular risk factor. Serum levels of ANGPTL4/8 and C-terminal domain-containing ANGPTL4 (CD-ANGPTL4) are positively associated with cardiovascular death, however, the underlying mechanisms remain incompletely understood. The present study investigated relationships of ANGPTL3, ANGPTL3/8, CD-ANGPTL4, and ANGPTL4/8 with coronary artery calcification (CAC) progression (using Agatston scores) and incident coronary events. ANGPTL3, ANGPTL3/8, CD-ANGPTL4, and ANGPTL4/8, were measured using dedicated immunoassays in participants of the Heinz Nixdorf Recall (HNR) study, an unselected, population-based cohort of subjects free from cardiovascular disease at baseline. CAC measurements were performed at baseline and after 5 years in 2887 participants, and there was follow-up for coronary events (median duration 18.8 years). Median Agatston scores increased over 5 years from 6.70 (t Associations of ANGPTL3 and ANGPTL3/8 with coronary atherosclerosis progression and incident coronary events were inconsistent, while CD-ANGPTL4 and ANGPTL4/8 were associated with both coronary atherosclerosis progression and incident coronary events. Associations of ANGPTL4/8 and CD-ANGPTL4 with cardiovascular events may reflect progression of coronary atherosclerosis conferred by diabetes, inflammation, or the potential intrinsic effects of CD-ANGPTL4 and ANGPTL4/8.

The aim of this study was to determine if retatrutide, a triple agonist of glucose-dependent insulinotropic polypeptide (GIP) receptor, glucagon-like peptide 1 (GLP-1) receptor and glucagon (GCG) receptor, may lower serum triglyceride (TG) and low-density lipoprotein cholesterol (LDL-C) levels in part by decreasing circulating concentrations of the angiopoietin-like protein 3/8 complex (ANGPTL3/8). In post-hoc analyses of two phase 2 retatrutide trials, concentrations of ANGPTL3/8, ANGPTL4/8 complex (ANGPTL4/8), ANGPTL3 and ANGPTL4 were measured using dedicated immunoassays to determine percent changes from baseline. Correlations of ANGPTL protein and complex levels with lipid and metabolic parameters at baseline were analysed. Correlations of the changes in ANGPTL protein and complex levels versus the changes in lipid and metabolic parameters at study endpoints were also analysed. Direct effects of retatrutide itself, GIP, GLP-1, GCG and a GCG receptor (GCGR) antagonist antibody on ANGPTL3/8 secretion were studied in vitro using primary human hepatocytes. ANGPTL3/8 reductions were observed with 8 and 12 mg retatrutide doses in participants with type 2 diabetes, and with 1, 4, 8 and 12 mg retatrutide doses in participants with obesity or overweight but without diabetes. In both cases, ANGPTL3/8 decreases paralleled retatrutide-induced reductions in TG and LDL-C. In primary human hepatocytes, both glucagon and retatrutide decreased ANGPTL3/8 secretion, and these reductions were blocked with the GCGR antagonist antibody. Together, these results suggest that the GCGR agonism of retatrutide could lead to reduced circulating ANGPTL3/8 concentrations, which may then contribute to decreases in TG and LDL-C levels.

We aimed to explore the heterogeneities and communication properties of cardiac CMs and ECs in diabetes. GSE213337 dataset was retrieved from NCBI Gene Expression Omnibus, containing the single-cell RNA sequencing data of hearts from the control and streptozotocin-induced diabetic mice. Cell cluster analysis was performed to identify the cell atlas. Data of CMs and ECs were extracted individually for re-cluster analysis, functional enrichment analysis and trajectory analysis. Cell communication analysis was conducted to explore the altered signals and significant ligand-receptor interactions. Eleven cell types were identified in the heart tissue. CMs were re-clustered into four subclusters, and cluster 4 was dominant in diabetic condition and enriched in cellular energy metabolism processes. ECs were re-clustered into six subclusters, and clusters 2, 4 and 5 were dominant in the diabetic condition and mainly enriched in cellular energy metabolism and lipid transport processes. The cellular communication network was altered in the diabetic heart. ECs dominated the overall signaling and notably increased the ANGPTL and SEMA4 signals in the diabetic heart. Four significant ligand-receptor pairs implicating the two signals contributed to the communication between ECs and other cell types, including Angptl1-(Itga1 + Itgb1), Angptl4-Cdh5, Angptl4-Sdc3, and Sema4a-(Nrp + Plxna2). The ligand Angptl4 engaged in ECs-CMs communication in a paracrine manner. Single-cell sequencing analysis revealed heterogeneities of ECs and CMs in diabetes, Angptl4-Cdh5 and Angptl4-Sdc3 were involved in the communication between ECs and CMs in diabetes. Show less

Angiopoietin‑like 4 (ANGPTL4), a member of the angiopoietin family, plays critical roles in angiogenesis, lipid metabolism and inflammation. It has been demonstrated that ANGPTL4 has significant influence on various diseases. Accumulating evidence has highlighted the impacts of ANGPTL4 on human malignancies. ANGPTL4 is commonly overexpressed in various types of cancer, such as breast, non‑small cell lung, gastric and colorectal cancer. Its upregulation promotes tumor growth, invasion, metastasis and angiogenesis, as well as metabolic reprogramming and resistance to programmed cell death, radiotherapy and chemotherapy. However, ANGPTL4 has also exhibited antitumor effects under certain conditions, indicating its complex roles in tumor biology. The transcriptional regulation of ANGPTL4 is influenced by multiple factors, such as HIF‑1, PPARs, TGF‑β and long non‑coding RNAs. In terms of signaling pathways, STATs, PI3K/AKT and COX-2/PGE2 are important in regulating cellular processes. The present review summarizes the biological functions of ANGPTL4 in tumors and its association with patient prognosis. Furthermore, the key molecular mechanisms and potential reasons for its dual roles in cancer are also discussed. In conclusion, ANGPTL4 is a valuable diagnostic biomarker and a potential therapeutic target for human cancers. Show less
