While family resilience is a recognized determinant of adaptation following stroke, the distinct, empirically derived profiles of family resilience among Chinese stroke survivor-caregiver dyads have not been clearly delineated. Identifying these profiles and their determinants is crucial for developing targeted interventions. To identify latent profiles of family resilience and examine the socio-demographic and clinical factors associated with profile membership among stroke patient-caregiver dyads in China. In this cross-sectional study, a convenience sample of 773 stroke survivor-caregiver dyads was recruited from three hospitals in Zhejiang Province, China. Latent profile analysis (LPA) was conducted on the 20-item Family Resilience Questionnaire (FRQ). Multinomial logistic regression was used to determine factors associated with profile membership. LPA supported a four-profile solution: Profile 1 "Low-Functioning Families" (22%), Profile 2 "Moderately Resilient - Low Cohesive Families" (24%), Profile 3 "Highly Resilient - Well-Functioning Families" (31%), and Profile 4 "High-Functioning - Optimistically Resilient Families" (24%). Multinomial logistic regression revealed that lower caregiver competence (higher FCTI scores) was strongly associated with profile membership (standardized aORs ranged from 2.58 to 43.19), whereas higher perceived social support (PSSS) was a significant protective factor (standardized aORs ranged from 0.03 to 0.19). Caregiver relationship and payment source were also significantly associated with profile membership. Family resilience among Chinese stroke families manifests in four distinct profiles, which are differentiated predominantly by caregiver competence and perceived social support. Our findings advocate for a precision family support paradigm, shifting from one-size-fits-all approaches to interventions tailored to distinct resilience profiles. Given the strong association, intervention programs should prioritize enhancing core caregiver competencies as a primary leverage point for building family resilience. Show less

Atherosclerotic plaque instability is a direct cause of cardiovascular and cerebrovascular events. In this study, a mitochondria-targeted liposome (LIP), modified with triphenylphosphonium (TPP) to enable specific mitochondrial delivery, was innovatively constructed to encapsulate a PCSK9 inhibitor (TPP-LIP@PCSK9). The aim was to explore a novel strategy for stabilizing plaques by restoring mitochondrial function in endothelial cells. Characterization results showed that TPP-LIP@PCSK9 possesses favorable nano-characteristics, and its targeting capability was confirmed through mitochondrial co-localization experiments.

Enlicitide decanoate, an oral proprotein convertase subtilisin-kexin type 9 (PCSK9) inhibitor, was shown to reduce low-density lipoprotein (LDL) cholesterol levels in a phase 2 trial; longer-term data are needed. In this multinational, double-blind, randomized, placebo-controlled trial, we enrolled adults with a history of a major atherosclerotic cardiovascular disease event with an LDL cholesterol level of 55 mg per deciliter or higher and those who were at risk for a first atherosclerotic cardiovascular disease event with an LDL cholesterol level of 70 mg per deciliter or higher. Participants were assigned in a 2:1 ratio to receive enlicitide at a dose of 20 mg or placebo daily for 52 weeks. The primary end point was the mean percent change in LDL cholesterol level from baseline to week 24. Key secondary end points were the mean percent change in LDL cholesterol level at week 52 and the mean percent change in levels of non-high-density lipoprotein (non-HDL) cholesterol and apolipoprotein B and the percent change in lipoprotein(a) level at week 24. Of the 2909 participants in the intention-to-treat population, 1935 received enlicitide and 969 received placebo (5 did not receive enlicitide or placebo). The mean age of the participants was 63 years, and 39.3% were women. The mean (±SD) LDL cholesterol level at baseline was 96.1±38.9 mg per deciliter. The mean percent change in LDL cholesterol levels at week 24 was -57.1% (95% confidence interval [CI], -61.8 to -52.5) with enlicitide and 3.0% (95% CI, 0.9 to 5.1) with placebo, representing an adjusted between-group difference of -55.8 percentage points (95% CI, -60.9 to -50.7; P<0.001). The mean percent change in LDL cholesterol level at week 52, the mean percent changes in non-HDL cholesterol and apolipoprotein B levels at week 24, and the percent change in lipoprotein(a) levels at week 24 were significantly greater with enlicitide than with placebo (P<0.001 for all comparisons). The incidence of adverse events did not appear to differ between the groups. Among participants who had a history of or were at risk for a first atherosclerotic cardiovascular disease event, treatment with the oral PCSK9 inhibitor enlicitide resulted in significantly lower LDL cholesterol levels than placebo at 24 weeks.

Chronic rhinosinusitis with nasal polyps (CRSwNP) is a prevalent inflammatory disorder characterized by nasal obstruction and polyp formation. Despite its prevalence, the complex pathogenesis of CRSwNP remains not fully understood, hindering the development of effective treatments. This study aims to delineate the immunological landscape of CRSwNP by integrating single-cell RNA sequencing (scRNA-seq) and Mendelian randomization (MR) approaches. We conducted a systematic MR analysis using summary statistics from genome-wide association studies (GWAS) and expression quantitative trait loci (eQTL) data. The identified genes were further scrutinized through scRNA-seq analysis of CRSwNP tissues to assess cell-specific expression patterns. Pathway enrichment and protein-protein interaction (PPI) network analyses were performed to explore the biological mechanisms underlying CRSwNP. The MR analysis identified several genes, including HLA-DRB1, HLA-DQA1, and HLA-DQB1, as significantly associated with CRSwNP. The scRNA-seq analysis validated these findings, revealing cell-specific enrichment in basal cells. Notably, these genes were found to be involved in immune cell recruitment and the reshaping of the immune microenvironment. Furthermore, the study highlighted the role of genes like TCF7L1, KANSL1-AS1, and POLR2J3, which showed contrasting expression patterns and potential regulatory roles in CRSwNP. This integrative study provides novel insights into the molecular and cellular underpinnings of CRSwNP. The identified genes and their role in immunopathogenesis offer potential therapeutic targets and highlight the importance of cell-specific gene expression in disease mechanisms. The combination of MR with scRNA-seq represents a powerful approach to elucidate complex traits and may pave the way for precision medicine in CRSwNP management. Show less

Conversion of cholesterol into bile acids is a central pathway for cholesterol disposal, which was mainly controlled by cholesterol 7alpha-hydroxylase (Cyp7a1). In present study, we aimed to investigate the effect and the potential underlying mechanism of microRNA-96 (miR-96) on atherosclerosis development. The anti-atherosclerosis effects of a miR-96 inhibitor (miR-96i) were evaluated using ApoE KO mice fed a high-fat diet, which was treated with miR-96i for 8 weeks. The regulatory mechanism was revealed and validated by RNA-seq transcriptomics, quantitative PCR and western blotting analyses in hepatic cells. The authors identified that miR-96i significantly decreased serum cholesterol and bile acid levels and attenuated arterial plaque in mice. We further revealed that miR-96 regulated Cyp7a1 via a FOXO1-involved indirect pathway, in which miR-96 directly modulated FOXO1 in a posttranscriptional manner. A coordinated regulatory effect of miR-96 and miR-185 on FOXO1 was also observed. The full spectrum of mechanisms underlying the antiatherosclerotic activity beside miR-96-FOXO1-CYP7A1 axis remains to be elucidated. This study provides convincing evidence for the pivotal role of miR-96 in FOXO1 modulation and CYP7A1-involved cholesterol-bile acid metabolism, suggesting that miR-96 is a novel therapeutic target for the discovery and development of drugs against ACVD.

Attention deficit hyperactivity disorder(ADHD), a common neurodevelopmental disorder in children, is characterized by inattention, hyperactivity, and impulsivity. Epidemiological surveys show that the prevalence of ADHD in children is gradually increasing worldwide, and it is the most common childhood mental disorder in China. Because of the complex clinical symptoms, multiple co-morbidities, and unknown etiology, ADHD has far-reaching negative impacts on individuals, families, and the society. Behavioral interventions, as a pillar in the management of ADHD, play a targeted role in improving children's social functioning, with significant benefits supported by evidence. However, they are constrained by uneven resources, poor compliance, and insufficient continuity, Western medicine has multiple adverse effects and unclear long-term effects in the treatment of ADHD despite the definite efficacy. Accordingly, there is an urgent need to find safe and effective therapies suitable for children. With a holistic view and treatment based on syndrome differentiation, traditional Chinese medicine(TCM) has significant advantages in treating ADHD via multiple targets, which involves dopamine(DA), norepinephrine(NE), 5-hydroxytryptamine(5-HT), cyclic adenosine monophosphate(cAMP), brain-derived neurotrophic factor(BDNF) and other signaling pathways. Through these pathways, TCM can treat ADHD through the regulation of neurotransmitters, enhancement of prefrontal and striatal functions, enhancement of neuronal protection, attenuation of neuroinflammation, and reduction of neuronal apoptosis. However, a systematic study remains to be conducted. This paper summarizes the signaling pathways related to the treatment of ADHD by TCM in the past two decades, aiming to provide reference for delving into the mechanism and exploring effective TCM prescriptions for ADHD in children and to give full play to the advantages of the efficacy and characteristics of TCM.

An 8-week experiment was conducted to evaluate the effects of dietary phosphatidylserine (PS) supplementation on juvenile large yellow croaker (Larimichthys crocea) fed high soybean oil (SO) diets. A fish oil control, an SO control, and four SO-based diets supplemented with 0.002%, 0.006%, 0.018%, or 0.054% PS were formulated. Results showed that weight gain exhibited quadratic responses to increasing PS levels. PS supplementation alleviated hepatic lipid deposition and reduced serum and hepatic lipid concentrations. At the molecular level, PS downregulated hepatic lipogenic gene expression including sterol regulatory element-binding protein 1 (srebp1), fatty acid synthase (fas), stearoyl-CoA desaturase 1 (scd1), and acetyl-CoA carboxylase 1 (acc1). Conversely, it upregulated hepatic lipid catabolism genes: peroxisome proliferator-activated receptor a (ppara), lipoprotein lipase (lpl), carnitine palmitoyltransferase 1 (cpt1), and diacylglycerol O-acyltransferase 1 (dgat1). Additionally, PS restored antioxidant enzyme activities and the expression of superoxide dismutase (sod1, sod3), glutathione peroxidase (gpx), and catalase (cat) in the liver. Furthermore, PS reduced hepatic pro-inflammatory cytokine mRNA levels: tumor necrosis factor α(tnf-α), cyclooxygenase 2 (cox-2), and interleukins (il-6, il-1β). In conclusion, dietary inclusion of 0.006%-0.018% PS effectively enhanced growth and antioxidant capacity, modulated lipid metabolism, and influenced inflammatory responses. Show less

Hypertrophic cardiomyopathy (HCM) arises from genetic mutations in sarcomere proteins, resulting in major structural abnormalities and limited treatment options. Patients with HCM had reduced expression of the FGF12 (fibroblast growth factor 12), but its precise functional role remains unclear. To explore FGF12's function and interactions, we utilized clustered regularly interspaced short palindromic repeats-Cas9 technology in cardiomyocytes derived from human induced pluripotent stem cells-induced cardiomyocytes, as well as in other cell lines and mouse models (MYH7 First, we observed a decrease in FGF12 expression and a difference in its subcellular localization in patients with HCM compared with healthy volunteers. In hypertrophic mouse models, injecting adeno-associated virus 9 reduced myocardial hypertrophy. FGF12 binds to calmodulin and inhibits its phosphorylation. This interaction also suppresses the expression and phosphorylation of downstream proteins, including CaMKII, ERK1/2, CREB1, and MCU. The nuclear-localization FGF12 binds to the promoter region of CREB1. FGF12 inhibits the expression of the CREB1-MCU axis expression, leading to reductions in both mitochondrial Ca This study reveals a pathological mechanism associated with HCM linked to FGF12. FGF12, located outside the nucleus, suppresses the expression of metabolism-related genes by reducing the phosphorylation levels within the calmodulin-ERK1/2-CREB1-MCU axis. In contrast, the nuclear localization of FGF12 facilitates its binding to the promoter regions of CREB1, inhibiting CREB1 expression. This dual action maintains cardiomyocyte function and mitochondrial homeostasis. Our findings position FGF12 as a promising therapeutic target for HCM. Show less

Coronary restenosis remains a major challenge following percutaneous coronary intervention (PCI), necessitating the development of effective stent-eluting drugs. Previous studies indicate that scutellarin protects vascular endothelial cells and exhibits anti-thrombotic and anti-platelet effects. Notably, our prior research demonstrated that scutellarin specifically counteracts oxidative stress-driven endothelial dysfunction, a key initiating event in restenosis. This combined evidence strongly suggests its potential against in-stent restenosis (ISR). Therefore, this study explores the efficacy of scutellarin in preventing ISR after PCI. We investigated scutellarin, derived from Erigeron breviscapus, for its potential to prevent ISR following PCI. The efficacy and mechanism of scutellarin were evaluated using both in vivo and in vitro models. An experimental atherosclerosis model was established in APOE In APOE This study establishes the efficacy of scutellarin in mitigating ISR using two complementary in vivo models. Scutellarin-eluting stents in atherosclerotic minipigs overcome translational barriers through full interventional simulation. Furthermore, scutellarin inhibits VSMCs proliferation, migration and promotes autophagy-coordinated apoptosis by the coordinated downregulation of both the Pl3K/AKT and lKKs/NF-κB cascades.These findings highlight scutellarin as a promising candidate for next-generation bioactive stent coatings, bridging phytopharmacology and precision interventional cardiology.

Human embryonic stem cell (hESC)-derived hepatocytes (hEHs) display functional deficits, particularly impaired albumin secretion and ammonia metabolism, compared to primary human hepatocytes (PHHs). Here, we investigated the regulatory role of CCAAT/enhancer-binding protein beta (C/EBPβ) in hepatocyte maturation. Forced C/EBPβ expression enhanced hepatocyte functionality and upregulated hepatocyte-specific genes, while suppressing epithelial-mesenchymal transition (EMT) via downregulating canonical EMT markers. Mechanistically, CUT&Tag and luciferase reporter assays confirmed C/EBPβ directly binds to the promoter regions of CDH1 (E-cadherin) and CPS1 (carbamoyl phosphate synthetase 1). Co-immunoprecipitation identified an interaction between C/EBPβ and the MAPK pathway. RNA interference combined with Western blot analysis revealed that MAPK1-mediated phosphorylation of C/EBPβ at Thr-235 augmented its transactivation activity, accelerating hepatocyte maturation. Our findings establish C/EBPβ as a master regulator that coordinates transcriptional networks and post-translational modifications during hEHs maturation, providing novel insights for generating mature hepatocytes for disease modeling and regenerative medicine applications. The transcriptional activity of C/EBPβ is regulated by MAPK1 protein within the ERK/MAPK signaling pathway. MAPK1 moves from the cytoplasm into the nucleus and transfers phosphate groups to C/EBPβ. This process reverses the "self-inhibition" state of C/EBPβ and enhances its transcriptional activity on downstream target genes. Show less

While active ingredients from compound Chinese herbal medicines (CCHMs) have demonstrated potential in alleviating symptoms of polycystic ovary syndrome (PCOS), their mechanisms of action remain insufficiently understood. This study aimed to identify key active ingredients and gene targets in Xiaochaihu Decoction, Sijunzi Decoction, and Shensiwei that contribute to their efficacy against PCOS. Transcriptomic data of PCOS were obtained from public databases. Information on gut microbiota metabolite-related targets and active ingredients of CCHMs was retrieved from relevant databases. Key gene targets and active ingredients were identified using Graph-based Bioactive Network Analysis (GraphBAN) and toxicological assessments. Molecular docking and dynamic simulations were conducted to validate interactions. Functional enrichment and regulatory network analysis were performed. LCT, FADS1, and CYP11A1 were identified as key genes associated with α-β T cell activation, immune receptor signaling, and adaptive immune responses. LCT and FADS1 were targeted by linolenic acid, while CYP11A1 was regulated by mandenol, EIC, and linolenic acid. Three microRNAs (hsa-miR-320a-3p, hsa-miR-4487, hsa-miR-6090) co-regulated these genes. Molecular docking and dynamics simulations confirmed stable binding between key genes and active ingredients, with binding energies < -5.0 kcal/mol. The findings indicate that CCHMs exert therapeutic effects on PCOS by multi-target regulation of key genes involved in androgen synthesis, metabolic regulation, and immune-inflammatory activation. The observed strong binding affinities provide a structural basis for these interactions. This study identified three key genes and three core active ingredients in CCHMs for PCOS treatment, laying a theoretical foundation for developing multi-target therapeutics. Show less

This study aims to evaluate the association between multiple lipid indices and coronary collateral circulation (CCC) in patients diagnosed with acute ST-segment elevation myocardial infarction (STEMI). This was a cross-sectional retrospective study involving 421 patients with STEMI who underwent coronary angiography between January 2022 and December 2024. Participants were categorized into a poor CCC group (Rentrop grade 0-1) and a good CCC group (Rentrop grade 2-3) according to Rentrop grading criteria. The following lipid parameters were evaluated as both continuous and categorical variables: total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), non-high-density lipoprotein cholesterol (non-HDL-C), lipoprotein(a) [Lp(a)], apolipoprotein B (ApoB), apolipoprotein A-I (ApoA-I), non-HDL-C/HDL-C, ApoB/ApoA-I, atherogenic index of plasma (AIP), and lipoprotein composite index (LCI). The associations between these lipid indices and CCC status were assessed using multivariate logistic regression and receiver operating characteristic (ROC) curve analysis. Multivariate logistic regression analysis revealed that higher HDL-C quartiles were significantly associated with reduced odds of poor CCC (odds ratio [OR]: 0.544, 95% confidence interval [CI]: 0.351-0.771, P < 0.05), whereas elevated LDL-C (OR: 29.299, 95% CI: 3.562-240.976, P < 0.05), non-HDL-C (OR: 50.140, 95% CI: 5.408-464.834, P < 0.01), and non-HDL-C/HDL-C (OR: 4.510, 95% CI: 1.186-25.368, P < 0.05) quartiles were significantly associated with increased odds of poor CCC. Receiver operating characteristic (ROC) curve analysis demonstrated that LDL-C (cutoff: 3.265, AUC: 0.647, 95% CI: 0.573-0.721, P < 0.001), non-HDL-C (cutoff: 2.735, AUC: 0.752, 95% CI: 0.688-0.816, P < 0.001), and non-HDL-C/HDL-C (cutoff: 2.393, AUC: 0.686, 95% CI: 0.611-0.761, P < 0.001) exhibited favorable predictive performance for poor CCC. Stratification analysis showed that the highest prevalence of poor CCC was observed in patients with concurrently elevated levels of LDL-C, non-HDL-C, and non-HDL-C/HDL-C. Several lipid indices-including LDL-C, non-HDL-C, and the non-HDL-C/HDL-C ratio-are significantly associated with impaired CCC in patients with STEMI. Notably, non-HDL-C exhibits the strongest association with CCC dyscrasia and therefore warrants early clinical attention. Show less

Validate the clinical utility of exosome cargo (miRNAs/proteins) and NLRP3/BDNF as key regulatory molecules for acupuncture-mediated spinal cord injury (SCI) recovery. From the establishment of the database to May 2025, a literature search was conducted on PubMed, and Embase, using keywords ["exosome cargo" or "exosome"], ["acupuncture" or "acupuncture and moxibustion" or "electroacupuncture" or "EA"], ["spinal cord injury" or "SCI"], ["immune regulation"], ["inflammatory reaction"], ["neuroregeneration" or "nerve"]. Including peer-reviewed studies on human/animal models, articles that do not meet the requirements are excluded. Preclinically, MSC-exosomal miR-145-5p suppressed TLR4/NF-κB signaling, reducing spinal IL-1β by 47% in SD rats. Schwann cell-exosomal MFG-E8 activated SOCS3/STAT3, increasing M2 macrophage CD206 by 63% and raising rat BBB scores by 3.8 points; Treg-exosomal miR-2861 upregulated tight junction proteins (occludin/ZO-1) to repair the blood-spinal cord barrier. Acupuncture (EA at GV14/GV4) upregulated spinal BDNF by 72% and NGF by 58% via Wnt/β-catenin, while EA at GV6/GV9 downregulated NLRP3 by 42-58% and TNF-α by 35-47%. Clinically, EA at EX-B2 increased ASIA scores by 3.2±1.1 points (Guo et al). Besides, 5x/week EA improved ASIA vs 3x/week (+6.4 points). EA+exercise reduced MAS by 1.6-2.9 points, with outcomes correlated to peripheral NLRP3 reduction, BDNF elevation, and MBI/WISCIII increases. Exosome cargo (miR-145-5p/MFG-E8) and NLRP3/BDNF are key regulatory molecules underlying acupuncture-mediated SCI recovery. However, limitations (small RCT samples, heterogeneous acupuncture protocols, unstandardized exosome isolation) hinder translation. Future work should focus on standardized biomarker detection, exosome engineering, and large-scale clinical trials. Show less

DUSP6, a dual-specificity phosphatase, has become a focal point in understanding the pathogenesis of various liver disorders. This study aims to investigate the role of DUSP6 in liver fibrosis and explore the underlying mechanism. Using a CCL4-induced mouse model, the consistent upregulation of DUSP6 expression was observed. Notably, when Dusp6 was knocked down, liver fibrosis showed significant improvement, revealing a protective effect intricately linked to the ERK pathway. This was accompanied by an increase in ferroptosis-related proteins SLC7A11 and GPX4, underscoring the role of ferroptosis, an iron-dependent form of regulated cell death, in this process. Transcriptomic analysis further revealed a crucial downregulation of Cyp2e1 following Dusp6 knockdown. In vitro, DUSP6 knockdown not only promoted ERK phosphorylation but also suppressed CYP2E1 expression, enhancing cell proliferation, bolstering hepatocyte resistance to ferroptosis, and alleviating hepatocyte injury. Importantly, inhibiting CYP2E1 in mouse models of liver fibrosis effectively slowed the progression. These findings illuminate a critical regulatory mechanism that DUSP6 regulates liver fibrosis via targeting ferroptosis, offering new a direction for therapeutic strategies in liver disease.

Non-small cell lung cancer (NSCLC) is the most common type of lung cancer and the leading cause of cancer-related deaths. Immune checkpoint inhibitors (ICIs) of programmed death-1 (PD-1)/programmed death ligand-1 signaling induce tumor regression in some patients with NSCLC, but most patients with NSCLC exhibit resistance to ICIs therapy. NSCLC shapes the potent tumor immunosuppressive microenvironment (TIME) that underlies tumor immune tolerance and acquired resistance. Therefore, elucidating the cellular and molecular mechanisms by which NSCLC establishes and sustains the TIME is essential for developing novel strategies to overcome immune resistance and enhance the clinical benefit of ICIs. The correlation between sterile alpha motif domain and histidine-aspartate domain-containing protein 1 (SAMHD1) expression and ICIs was analyzed via immunohistochemistry. Cell migration assay was performed to assess the effect of SAMHD1 on macrophage recruitment. Multicolor flow cytometry was performed to analyze the effect of SAMHD1 knockdown on the tumor microenvironment. SAMHD1 regulation of the dual specificity phosphatase 6-extracellular regulated protein kinases 1/2 (DUSP6-ERK1/2) pathway was verified by RNA sequencing and western blotting. Here, we identify the SAMHD1 as a potential therapeutic target and a major determinant of poor response to ICIs in patients with NSCLC. Tumors with high SAMHD1 expression show resistance to anti-PD-1 antibody (αPD-1) treatment, whereas tumors with low SAMHD1 expression are highly sensitive. SAMHD1-dependent resistance to αPD-1 is characterized by increased tumor-associated macrophages (TAMs) infiltration and reduced CD8+T cell numbers. Mechanistically, SAMHD1 regulates the expression of macrophage-associated chemokines by influencing the activation of the DUSP6-ERK1/2 pathway, which contributes to TAMs aggregation within NSCLC tumors to shape an immunosuppressive microenvironment. The HIV accessory protein viral protein-x (VPX) specifically degrades SAMHD1 to promote HIV replication. Similarly, the vpx-engineered oncolytic adenovirus (oAd-vpx) targets SAMDH1 degradation to enhance oncolytic adenovirus replication and weaken the hostile immune microenvironment shaped by TAMs, thereby triggering a CD8+T-cell-dependent antitumor immune response. The combination of oAd-vpx and αPD-1 inhibits tumor growth and enhances sensitivity to ICIs in both mouse and human NSCLC. This research identifies a key mechanism of SAMHD1-driven immunosuppression and highlights its important role in oncolytic adenovirus therapy. This study provides a theoretical basis for targeting SAMHD1 as a drug therapy strategy in patients with NSCLC. Show less

To explore the associations between accelerometer-measured physical activity patterns and cardiovascular diseases (CVD), CVD-cause mortality, and all-cause mortality in people with osteoarthritis (OA). OA participants from the UK biobank with ≥36 h of accelerometer data, collected over one-week, were analyzed. Moderate to vigorous physical activity (MVPA) patterns were classified as: 'weekend warriors' (≥150 min/week, >50% on 1-2 days), active regular (>150 min/week), or inactive (<150 min/week). Mean min per week of light physical activity (LPA) were categorized into quartiles based on the distribution in the analytical sample. Among 10 210 study participants (mean age 58.1 ± 7.1 years; 64.5% female) followed for a median of 6.9 years, there were 1,538 incident cases of CVD, and 358 deaths, including 90 from CVD. Compared with inactive MVPA, both weekend warrior (adjusted hazard ratio, aHR (95% CIs); 0.73 (0.64-0.82)) and active regular MVPA (0.75 (0.65-0.87)) significantly lowered the risks of incident CVD. Notably, only the weekend warrior group showed significant reductions in CVD-cause mortality (0.55, 0.33-0.92), and all-cause mortality (0.75 (0.59-0.96)). Higher levels of LPA may link to lower CVD, CVD-cause mortality, and all-cause mortality risks in a dose-response manner. Subgroup analysis indicated that more prominent associations were found in individuals with a body mass index >30 or those aged over 60. Engaging in a weekend warrior pattern may confer unique survival benefits for OA patients, especially among older adults and those with obesity. LPA may have dose-dependent protective effects for CVD and mortality risk in OA patients. Show less

Both inhibition of NLRP3 and NCL knockdown alleviated atherosclerotic lesion severity in ApoE This study demonstrates that, in AS, NCL exacerbates EC pyroptosis and promotes disease progression by facilitating nuclear transport of RASSF2. This study defines the mechanistic roles of NCL in AS, thereby identifying a new molecular pathway and suggesting potential therapeutic targets. Show less

Facial nerve injury (FNI) is a common peripheral neuropathy that severely impairs facial function and quality of life. Qianzheng Powder (QZP) is a traditional Chinese herbal formula used to treat facial paralysis clinically, yet its neuroprotective mechanisms remain unclear. This study aims to evaluate the therapeutic effects of QZP on FNI and potential underlying mechanisms. A FNI model was established in male C57BL/6 mice by performing facial nerve crush surgery. QZP (3.51 g/kg) was administered orally once daily for 14 days post-surgery. Facial function was assessed behaviorally. Tissue samples were collected on day 21 for histological evaluation, qPCR and Western blotting. Liver and kidney safety were also assessed via H&E staining and serum biochemical markers. QZP significantly improved facial motor function from day 7 post-injury. Additionally, QZP treatment mitigated neuronal loss in the facial motor nucleus, attenuated buccinator muscle atrophy, and enhanced myelin regeneration, as evidenced by increased MPZ and MBP expression. These were consistent with the increace of the BDNF, TrkB, and QZP promotes structural and functional recovery of facial nerve following injury, likely through activation of the BDNF/TrkB/CREB axis, and demonstrates a favorable safety profile. These findings support its potential as a therapeutic adjunct in peripheral nerve repair. Show less

Digital technology is frequently regarded as a tool to alleviate loneliness and enhance mental health among older adults, yet its effectiveness remains contested. This study explores whether digital exclusion moderates the association between loneliness and depressive, and examines symptom structure and depressive subtypes. Drawing on data form the 2018 and 2020 waves of the CHARLS (N = 13,719), we employed fixed-effect and mixed-effect models to assess the effect of loneliness on depressive and the moderating role of digital exclusion. Latent profile analysis (LPA) was used to identify symptoms subtypes, while symptom network analysis assessed centrality and network stability. Loneliness significantly predicted depressive symptoms across multiple models, demonstrating robust effects. Digital exclusion was positively associated with depressive symptoms but did not exhibit a statistically significant moderating effect on the loneliness-depression relationship (p > 0.05, Δβ ≈ 0.011). LPA identified six psychologically meaningful subtypes of depression. Symptom network analysis revealed that emotional and motivational symptoms occupied central positions within the network structure, whereas loneliness, despite its strong connections, exhibited relatively low centrality. The overall network structure remained stable over two years, with the digital access group exhibiting stronger network connectivity. This study emphasizes that digital access alone is not a universal remedy for alleviating loneliness. The psychological benefits of digital technology depend on the alignment between individual motivations, usage patterns, and broader social contexts. Future research should focus on digital usage quality and contextual adaptability of interventions, promoting a shift from customization in digital mental health intervention strategies. Show less

Identifying high-performing advanced practice nursing roles and understanding the factors that contribute to their effectiveness are critical for advancing professional development, optimizing workforce deployment, and ensuring long-term sustainability in nursing. This study aimed to (1) identify distinct latent profiles of advanced practice nursing among specialist nurses in mainland China, (2) quantitatively examine the individual and contextual factors associated with high performance, as characterized by these profiles, and (3) qualitatively confirm the significant factors using explanatory semistructured interviews in the high-performance groups. A mixed-methods sequential explanatory design was used, in which quantitative data were collected first and subsequently explained through qualitative interviews. Certified specialist nurses from 16 hospitals across urban and rural areas of Shanghai were included. Latent profile analysis (LPA) was conducted using the five domains from the Advanced Practice Role Delineation tool as manifest indicators to classify nurses into distinct performance profiles. Multinomial logistic regression was used to examine potential determinants (e.g., job position) of group membership. Additionally, a backpropagation neural network (BPNN) was developed to rank the importance of contributing factors. Specialist nurses identified as high performers in the quantitative phase were purposively sampled for explanatory semistructured qualitative interviews. Three latent profiles emerged: high performance (26.1%), moderate performance (46.3%), and low performance (27.6%). Compared to APNs, staff nurses had significantly lower odds of belonging to the high-performance group ( Identifying the profiles of advanced practice nursing roles provides valuable insights for optimizing APN performance and informing targeted management and policy strategies. High-performing specialist nurses are positioned at the nexus of individual capability, interdisciplinary collaboration, and institutional support. Show less

Background Although substantial evidence has demonstrated the impact of obesity on brain structure and cognition, the heterogeneity of adiposity-particularly in terms of fat distribution patterns-and its differential neurologic effects remain poorly understood. Purpose To identify body fat distribution patterns with MRI and latent profile analysis (LPA) and their associations with brain structure measurements, cognition, and neurologic diseases. Materials and Methods This secondary analysis used prospective data from the UK Biobank, including health records and MRI scans of the brain, heart, and abdomen. Fat distribution profiles were classified using LPA based on eight body mass index (BMI)-adjusted MRI-derived fat quantification metrics. Differences in brain volume, white matter properties, cognition, and the risk of neurologic disorders were analyzed across profiles and relative to a benchmark lean profile; analyses were stratified by sex. Group differences were examined using analysis of covariance (ANCOVA) or rank-based ANCOVA. Results Among 25 997 participants (mean age, 55 years ± 7.4 [SD]; 13 536 female participants), LPA identified six profiles of body fat distribution in both sexes. Four high-adiposity patterns were identified, including the pancreatic-predominant profile (profile 1), with elevated proton density fat fraction (mean BMI-adjusted Show less

Clinical application of mesenchymal stem cells for endometrial repair has been hampered by variability in cell quality, large-scale production, and uncertainty regarding the optimal delivery route. In this study, we investigated the therapeutic potential of clinical-grade human embryonic stem cell-derived immunity-and-matrix-regulatory cells (IMRCs) for treating refractory moderate-to-severe intrauterine adhesion (IUA). In a rabbit IUA model, sub-endometrial injection of IMRCs significantly reduced fibrosis and enhanced endometrial angiogenesis, outperforming uterine perfusion. Transcriptomic analysis revealed distinct pro-angiogenic gene expression profiles between the two delivery routes. In vitro, IMRCs co-cultured with endometrial stromal cells (ESCs) markedly enhanced angiogenic potential compared to either cell type alone. Protein array analysis of the co-culture supernatant showed elevated levels of angiogenic factors, with functional assays confirming that inhibition of ANGPTL4, a non-canonical pro-angiogenic mediator, impaired angiogenesis. In a first-in-human, single-center, phase 1 dose-escalation trial involving 18 patients with refractory IUA, high-dose sub-endometrial IMRC injection promoted angiogenesis, reduced uterine scarring, and improved pregnancy outcomes, with no safety concerns observed over 3 years of follow-up. These findings highlight the translational promise of IMRCs as a novel therapeutic strategy for endometrial regeneration in severe IUA. Show less

Neurodegenerative and psychiatric disorders share overlapping molecular mechanisms, including neuroinflammation, oxidative stress, and neurotransmitter dysregulation. Essential oils from Lavandula angustifolia (TLEO) and Rosa rugosa (PREO) contain neuroactive compounds with therapeutic potential, but their mechanisms remain poorly defined. This study aimed to elucidate the shared and distinct molecular targets and pathways of TLEO and PREO using a multi-scale computational strategy. Compounds identified by GC-MS were evaluated through ADMET profiling, target prediction, and disease-target intersection analysis. Enrichment, network, docking, and dynamics analyses were performed on shared protein-coding targets between essential oils and twelve brain disorders, including seven neurodegenerative conditions (Alzheimer's disease, amyotrophic lateral sclerosis, Friedreich ataxia, Huntington's disease, Lewy body disease, Parkinson's disease, spinal muscular atrophy) and five psychiatric disorders (autism spectrum disorder, attention deficit-hyperactivity disorder, bipolar disorder, major depressive disorder, and schizophrenia). A total of 110 compounds yielded 252 common targets, with CHRM2 (GPCR) and NR1H3 (non-GPCR) identified as key hubs. Docking suggested strong binding affinities for caryophyllene oxide at CHRM2 (-7.3 kcal/mol) and α-himachalene at NR1H3 (-8.5 kcal/mol). Molecular dynamics simulations confirmed stable, compact complexes with low RMSD and SASA values. MM/PBSA free energy calculations quantitatively validated these interactions, revealing favorable binding energetics driven predominantly by van der Waals and hydrophobic contributions, consistent with the terpenoid chemical profiles. Functional enrichment highlighted involvement in cholinergic signaling, lipid metabolism, and inflammatory regulation. This study demonstrates that PREO and TLEO can modulate multiple targets relevant to brain disorders through both GPCR and non-GPCR mechanisms. These findings provide a computationally inferred mechanistic framework for the potential neuroprotective synergy of these oils and highlight essential oil-derived compounds as promising leads for further experimental investigation.
