Improved internet access has exposed rural adolescents in China to a greater risk of internet addiction. However, existing studies seldom examine the relationship between dynamic changes in internet addiction and psychosocial maladjustment. This study aims to explore the transition patterns of internet addiction and its associations with emotional and interpersonal problems over time. A one-year longitudinal survey was conducted among 782 middle school students in rural China. Latent Profile Analysis (LPA) was conducted to identify internet addiction profiles at two time points. Latent Profile Transition Analysis (LPTA) was then used to examine the transition patterns between profiles over time. Subsequently, statistical analyses were conducted to explore how these transitions were associated with emotional and interpersonal problems. Three profiles of internet addiction were identified: minimal-internet addiction, low-internet addiction, and high-internet addiction. Based on LPTA, most adolescents with higher internet addiction at T1 shifted to lower-severity profiles over time (high → minimal: 35.3%; low → minimal: 39.8%; high → low: 33.3%), while some with initially lower levels transitioned to more severe profiles (minimal → high: 6.9%; low → high: 12.2%; minimal → low: 25.7%). Transition into higher addiction profiles predicted increased depression, anxiety, and poorer relationships with parents, peers, and teachers. Conversely, reductions in addiction were linked to improved depressive symptoms. Changes in internet addiction have an impact on adolescent psychosocial maladjustment. Early detection and flexible interventions are essential in rural settings. Show less

Metabolic reprogramming of Branched-chain amino acids (BCAAs)-leucine, isoleucine, and valine-has emerged as a constitutive feature of cancer, extending far beyond their canonical roles in protein synthesis and energy provision. In malignancy, these essential amino acids function as pivotal signaling mediators and epigenetic modulators, thereby propelling tumor progression, facilitating immune evasion, and conferring resistance to therapeutic agents. This review delineates how cancer cells subvert branched-chain amino acid metabolism to fuel anabolic processes, activate oncogenic signaling cascades including mTOR and PI3K/AKT, and remodel the tumor microenvironment. A framework is presented to categorize the differential reliance of various cancers on key catabolic enzymes-BCAT1, BCAT2 and BCKDK-underscoring their therapeutic vulnerability. The paradoxical role of BCAAs in modulating anti-tumor immunity is examined alongside the potential of dietary modulation and the development of pharmacological inhibitors targeting this pathway. Concluding perspectives highlight the trajectory for translating these insights into precision oncology, advocating for biomarker-guided and context-specific therapeutic strategies. Show less

Families with children diagnosed with autism spectrum disorder (ASD) often encounter significant challenges, manifesting in elevated stress levels and compromised physical and mental well-being. This study employed Latent Profile Analysis (LPA) to comprehensively examine family resilience attributes among 328 Chinese parents of children with ASD. Drawing on Walsh's family resilience framework and the Double ABCX stress-adaptation model, the research examined how protective factors (social support, posttraumatic growth) and risk factors (family stressors) distinctively characterize resilience profiles and predict profile membership, alongside sociodemographic correlates. Through rigorous statistical analysis, the following three distinct family resilience profiles emerged: adversity (32.31%; characterized by low resilience), ordinary (46.65%; demonstrating moderate resilience) and growth (21.03%; exhibiting high resilience). Critically, the findings revealed that higher family income, perceived social support and posttraumatic growth were associated with higher family resilience, while family stressors were associated with lower family resilience. These insights underscore the importance of developing targeted, personalized intervention strategies that can effectively enhance familial coping mechanisms and psychological adaptation for families navigating the complex challenges of ASD.

High-density lipoprotein(a) (Lp(a)) is a well-established independent risk factor for atherosclerotic cardiovascular diseases (ASCVD). However, the interaction between Lp(a), low-density lipoprotein cholesterol (LDL-C), and polygenic risk score (PRS) in cardiovascular diseases has been the subject of relatively limited research. The present study included a total of 346,751 participants from the UK Biobank. According to the guideline of Lp(a), the study subjects were divided into 3 groups: the first group was <75 mmol/L (n = 272,643), the second group was 75 to 125 mmol/L (n = 35,792), and the third group was >125 mmol/L (n = 38,316). Elevated Lp(a) levels were associated with a progressively increased risk of overall cardiovascular events (CVEs), including ischemic stroke (IS), coronary heart disease (CHD), angina pectoris, and myocardial infarction (MI). In contrast, the risks of atrial fibrillation (AF) and heart failure (HF) decreased with higher Lp(a) levels. Additive interaction analyses revealed significant synergistic effects between Lp(a) and LDL-C for CHD (relative excess risk interaction [RERI] = 0.081, attributable proportion of interaction [AP] = 0.046, synergy index [SI] = 1.117), angina pectoris (RERI = 0.112, AP = 0.055, SI = 1.121), and MI (RERI = 0.183, AP = 0.079, SI = 1.161), with MI showing the strongest synergy. Incorporating PRS further amplified these effects, and the RERI (CHD: RERI = 0.721; angina pectoris: RERI = 0.781; MI: RERI = 1.318) and SI (CHD: SI = 2.218; angina pectoris: SI = 1.97; MI: SI = 2.326) were significantly higher than those of the interaction model containing only Lp(a) and LDL-C. In conclusion, Lp(a) and LDL-C show a significant synergistic effect in ASCVD, and this effect is more prominent in individuals with a higher PRS, suggesting that dual lipid management should be strengthened for such populations. While AF and HF may require alternative risk factor management. Show less

Anshen Bunao Syrup (ABS), a traditional Chinese medicinal formula, is widely used to treat neurological disorders such as insomnia, dizziness, and neurasthenia. However, its antidepressant effect and underlying mechanisms remain insufficiently characterized. This study aims to comprehensively evaluate the antidepressant effect of ABS in a rat model, and to elucidate the underlying mechanism. Chronic unpredictable mild stress (CUMS) induced depressive rats were used to evaluate the antidepressant effect of ABS. Histopathological alterations in the hippocampus and colonic mucosa were examined using Nissl and H&E staining. Microglial activation was evaluated by Iba-1 immunohistochemical staining. Gut microbiota composition and metabolic profiles were analyzed using 16S rRNA sequencing and untargeted metabolomics. Differential gene expression and pathway regulation were investigated by transcriptomics and confirmed by Western Blot (WB). ABS significantly ameliorated depressive-like behaviors and elevated dopamine and 5-Hydroxytryptamine levels in cortical regions. Furthermore, ABS mitigated hippocampal neuronal damage, suppressed microglial overactivation and reduced oxidative stress in the cortex. 16S rRNA sequencing analysis showed that ABS exerted antidepressant effects via modulation of the "microbiota-gut-brain" axis, particularly by altering intestinal microbiota composition, enhancing gut function, and suppressing HPA axis hyperactivity. Metabolomics revealed that ABS corrected metabolic disturbances, and alleviated inflammation-related metabolic disturbances, while transcriptomics indicated regulation of the Npas4-BDNF-PI3K/AKT signaling pathway, which was further confirmed by WB. ABS significantly ameliorated depression in a CUMS rat model, primarily through coordinated regulation of gut microbiota, metabolic homeostasis, and the Npas4-BDNF-PI3K/AKT signaling pathway, providing integrative mechanistic insights into its antidepressant effects.

This study aimed to analyze the clinical features, genetic basis, and management of late-onset carbamoyl phosphate synthetase 1 deficiency (CPS1D) through a pediatric case report and literature review, highlighting diagnostic challenges and therapeutic strategies. We present a 19-year-old female with recurrent neurological symptoms since age 8. She underwent comprehensive metabolic screening, neuroimaging, and whole-exome sequencing of theCPS1gene. Identified variants were assessed for pathogenicity using multiple orthogonalin silicoprediction tools. The patient's initial hyperammonemic crisis at age 8 was misdiagnosed as encephalitis. Workup at age 13 confirmed hyperammonemia (peak 168 µmol/L), hypocitrullinemia, and elevated glutamine. Genetic analysis identified compound heterozygousCPS1variants: a novel c.1058 T > C (p.F353S) and known pathogenic c.1145C > T (p.P382L). A self-selected low-protein diet controlled acute crises but led to severe growth failure (height 145 cm, weight 30 kg). Late-onset CPS1D's nonspecific neurological symptoms often lead to misdiagnosis. Diagnosis requires a high index of suspicion, integrating metabolic profiling with genetic confirmation. This case expands the pathogenic genotypic spectrum of CPS1D. It crucially highlights that while dietary management is life-saving, it requires expert multidisciplinary oversight to prevent devastating consequences like growth failure, especially in resource-limited settings. Routine ammonia testing in unexplained encephalopathy is paramount. Show less

Excessive fat deposition compromises the health of companion animals and the carcass quality of food-producing livestock. Follicle-stimulating hormone (FSH) has been demonstrated to play a critical regulatory role in fat deposition, with its function dependent on binding to its cognate receptor (FSHR) in target organs. In this study, female Sprague-Dawley (SD) rats were immunized with subunit vaccines targeting FSHβ and FSHR, respectively, and obesity was induced by a high-fat diet (HFD) to investigate the effects of these vaccines on adipose deposition in female mammals. The results revealed that active immunization against FSHβ and FSHR effectively suppressed HFD-induced obesity and the elevated serum triglyceride levels. Histological observations found that FSHβ and FSHR immunity decreased adipocyte hypertrophy and increased the cross-sectional area of skeletal muscle fibers caused by HFD, partially ameliorated HFD-associated hepatic sinusoidal spaces and vacuolated steatosis in the cytoplasm. RT-qPCR results indicated that FSHβ and FSHR immunization inhibited lipid synthesis by downregulating adipogenic-related genes, including C/ebpα, Creb, Pparγ, Lpl, and Perilipin. These findings suggest that both vaccines can mitigate HFD-induced adipose deposition in rats, with the FSHR vaccine exhibiting more pronounced effects. This study provides a novel strategy to mitigate pet health deterioration caused by excessive obesity and the decline in carcass quality of food-producing livestock. Show less

Lipoprotein(a) [Lp(a)] is a genetically determined independent risk factor for atherosclerotic cardiovascular disease (ASCVD) that drives a significant residual risk through proatherogenic, proinflammatory, and prothrombotic pathways. However, current mainstay lipid-lowering therapies such as statins have limited efficacy in reducing Lp(a) levels, highlighting a critical therapeutic gap. This review aims to synthesize evidence on the role of Proprotein Convertase Subtilisin/Kexin Type 9 (PCSK9) inhibitors in targeting Lp(a). We systematically searched PubMed and Embase for clinical trials and mechanistic studies (2010-2025), using the PRISMA and AMSTAR-2 frameworks to ensure methodological rigor and demonstrated that PCSK9 inhibitors (eg, alirocumab, evolocumab, and tafolecimab) not only reduced low-density lipoprotein (LDL-C) by 55%-60% but also lowered Lp(a) by 20%-30%. The efficacy of these agents varies ethnically, with tafolecimab showing superior performance in East Asian populations, which is partly attributable to the higher prevalence of the PCSK9 R46L loss-of-function allele. Mechanistically, PCSK9 inhibitors lowered Lp(a) levels through 2 pathways: suppression of hepatic synthesis and enhanced plasma clearance. This evidence supports the 2023 ESC guidelines, which issued a Class IIa recommendation for PCSK9 inhibitor use in patients with ASCVD and elevated Lp(a) levels. Given the evolving landscape, further research is warranted to confirm the role of these therapies in precision medicine paradigms for managing Lp(a)-associated risks. Show less

This study established a hyperlipidemia model by feeding Sprague-Dawley rats a high-fat diet for 8 weeks. The rats were randomly assigned to the following groups: model group, atorvastatin calcium group(4.8 mg·kg~(-1)), low-, medium-, and high-dose Tanyu Tongzhi Optimization Decoction(TYTZD) groups(3.6, 7.2, and 14.4 g·kg~(-1)), and a normal diet control group. After 4 weeks of continuous administration, hematoxylin-eosin(HE) and oil red O staining were used to observe liver pathological changes and lipid infiltration. Automatic biochemical analyzer were performed to assess blood lipid profiles, coagulation function, and liver function. Transcriptomic and proteomic analyses were employed to identify differentially expressed genes(DEGs) and proteins(DEPs), followed by enrichment analysis. The MCODE algorithm was applied to classify DEGs and DEPs into modules, and network separation index(S₍AB)) was calculated to assess module separation, enabling construction of a gene-protein co-expression network for core target screening. The diagnostic accuracy of core targets was evaluated by area under the receiver operating characteristic(ROC) curve(AUC), and ELISA was used to measure core target expression. Western blot detected the expression of core pathway-related proteins in liver tissue. RESULTS:: demonstrated that TYTZD significantly improved dyslipidemia, coagulation dysfunction, liver injury, hepatic pathology, and lipid infiltration in hyperlipidemic rats. Transcriptomic analysis identified 571 DEGs significantly reversed by TYTZD, mainly enriched in inflammatory signaling pathways such as Toll-like receptor 4(TLR4)/nuclear factor-κB(NF-κB). Proteomic analysis identified 102 reversed DEPs, mainly involved in cholesterol metabolism pathways. Integrated analysis identified core targets including TLR4, tumor necrosis factor-α(TNF-α), integrin subunit alpha M(ITGAM), Toll-like receptor 2(TLR2), matrix metalloproteinase 9(MMP9), interleukin-1β(IL-1β), apolipoprotein E(APOE), and apolipoprotein C2(APOC2), all with AUC values greater than 0.70. ELISA showed that TYTZD intervention significantly downregulated MMP9, TNF-α, IL-1β, TLR2, ITGAM, and TLR4, and upregulated APOC2 and APOE. Western blot indicated that TYTZD reduced TLR4, p-NF-κB, and IL-1β protein expression in liver tissue. In conclusion, TYTZD may exert anti-hyperlipidemic effects through regulation of core targets such as ITGAM, TLR4, and APOC2, and by modulating the TLR4/NF-κB signaling pathway to intervene in inflammatory responses and cholesterol metabolism, thereby achieving multi-target, multi-pathway therapeutic effects against hyperlipidemia.

High-dose methotrexate for pediatric cancer treatment is frequently associated with mucositis, which can lead to delayed or discontinued treatment and impact survival. While individual genetic variants have been implicated, the cumulative impact of genetic variation within relevant biological pathways remains unexplored. We evaluated single nucleotide polymorphisms across 18 pathways previously identified as relevant to mucositis in 278 pediatric patients with acute lymphoblastic leukemia from six academic health centers across Canada. Pathway enrichment was assessed using the Joint Association of Genetic variants tool, and a predictive model was developed using XGBoost, a supervised machine learning algorithm based on gradient-boosted decision trees. Pathway enrichment identified significant associations in IL6 (P = 0.04) and WNT/β-catenin (P = 0.048) signaling pathways. The predictive model (area under the curve [AUC] = 0.76) highlighted single nucleotide polymorphisms associated with inflammation- and mucosa-related genes, including PRKCD, IL17B, MAST3, and CAPN9, with both risk and protective effects. Model performance dropped by 0.15 in AUC (from 0.76 to 0.61) after removing single nucleotide polymorphism features, underscoring their predictive value. This pathway-informed approach identifies genetic contributors to methotrexate-induced mucositis and supports polygenic risk prediction. Our findings provide a foundation for individualized toxicity risk profiling and suggest potential therapeutic targets to mitigate treatment-limiting mucositis in pediatric oncology. Show less

Periodontal ligament stem cells (PDLSCs) hold great promise for periodontal regeneration therapy. However, their self-renewal and multilineage differentiation capabilities are often compromised by adverse factors in the periodontal microenvironment. Therefore, identifying novel therapeutic targets and elucidating the underlying molecular mechanisms to protect the proliferative and differentiation potential of PDLSCs is of significant importance. PDLSCs were exposed to electronic cigarette extract and various common oral stressors to evaluate the expression of glucagon such as peptide 1 receptor (GLP1R) and gastric inhibitory polypeptide receptor (GIPR). PDLSCs isolated from patients with periodontitis and PDLSCs from a mouse periodontitis model were also analyzed. Functional studies were performed by GLP1R or GIPR knockdown, overexpression, and treatment with single or dual receptor agonists, followed by assessment of cell proliferation and multilineage differentiation capacities. Transcriptome (RNA-seq), chromatin immunoprecipitation sequencing (ChIP-seq), and RNA immunoprecipitation sequencing (RIP-seq) were applied to delineate downstream signaling pathways and RNA–protein interactions. Protein synthesis regulation was further investigated by immunoprecipitation of interferon induced protein with tetratricopeptide repeats (IFIT)-associated translation initiation factors. For in vivo validation, wild-type and GLP1R/GIPR double-knockout periodontitis mice were transplanted with CRISPR-Cas9 mCherry-labeled PDLSCs and treated with receptor agonists. Disease severity and PDLSC fate were evaluated by histology and lineage tracing. Finally, a questionnaire-based survey was conducted in 150 patients with periodontitis, including 74 individuals with long-term use (> 1 month) of GLP1R or GLP1R/GIPR dual agonists (e.g., semaglutide, liraglutide, tirzepatide), to assess their periodontal outcomes. GLP1R and GIPR expression were markedly downregulated in PDLSCs exposed to multiple stressors and in PDLSCs isolated from periodontitis specimens. RNA-seq, ChIP-seq, and RIP-seq identified downstream pathways and RNA–protein interactions implicated in receptor-mediated regulation. Functionally, GIPR agonism promoted PDLSC proliferation via activation of the mitogen-activated protein kinase (MAPK)/extracellular signal-regulated kinase (ERK) pathway, whereas GLP1R agonist enhanced multilineage differentiation capacity in vitro. Mechanistically, GLP1R knockdown induced robust upregulation of IFIT1/2/3, while GLP1R agonist suppressed IFIT expression. IFIT1/2/3 were shown to interact with eIF3C and to inhibit translation of differentiation-related mRNAs, linking GLP1R signaling to translational control of PDLSC fate. In vivo, transplantation experiments in both wild-type and GLP1R/GIPR double-knockout periodontitis mice demonstrated that single and dual receptor agonists significantly improved endogenous and exogenous PDLSC-mediated periodontal regeneration. Consistently, a clinical survey of 150 patients with periodontitis (74 receiving GLP1R or dual agonists) revealed significantly better periodontal staging and grading in treated individuals, with longer agonist exposure associated with greater improvement. Our findings uncover the different molecular roles of GIPR and GLP1R in self-renewal capacity and multipotency of PDLSCs, and open new avenues for developing therapeutic targets and strategies in oral tissue engineering and regenerative medicine.

Lung adenocarcinoma (LUAD) is the most common subtype of lung cancer and is difficult to distinguish from benign pulmonary nodules (BPNs), particularly at early stages. Extracellular vesicles (EVs) represent a promising source of biomarkers for the diagnosis of malignant pulmonary nodules. This study aimed to identify robust and clinically relevant EV-based protein biomarkers via isolation with EXODUS, a system that enables efficient direct capture of plasma EVs, followed by data-independent acquisition mass spectrometry (DIA-MS) for in-depth proteomic profiling. A total of 1383 proteins were identified from the plasma EVs obtained from 25 individuals (10 BPN and 15 early stage LUAD), while dysregulated protein signatures were revealed through differential expression analysis. Machine learning algorithms incorporating demographic variables, imaging features, EV protein profiles, and conventional tumor markers were applied to select diagnostic candidates. Random forest analysis revealed two upregulated proteins, NTN3 and APOA4, as promising biomarkers. Subsequently, their diagnostic performance and net clinical benefits were validated in an independent EV cohort (6 LUAD and 6 BPN) using ELISAs and decision curve analysis. In summary, we present an integrated pipeline that combines EXODUS-based isolation, DIA-MS, and machine learning to detect markers from plasma EVs for distinguishing early stage lung cancer from benign nodules.

Platelets must balance hemostatic function with pathological thrombosis, particularly under metabolic stress conditions. MAPKs are central to platelet responses, but how these platelet signals differentially regulate hemostasis remains poorly understood. To investigate the role of Traf2/Nck-interacting kinase (TNIK), we generated megakaryocyte/platelet-specific TNIK knockout mice (Tnikf/fPF4-Cre+) and evaluated platelet function, hemostasis, and thrombosis under normal and hyperlipidemic conditions using chimeric Tnikf/fPF4-Cre+Apoe-/-mice fed high-fat diets. TNIK-deficient mice exhibited prolonged bleeding times, delayed arterial thrombosis and reduced platelet activation under normal conditions, primarily due to impaired dense granule secretion. Mechanistically, TNIK interacted with c-Jun N-terminal kinase interacting protein 1 to promote mixed lineage kinase 3/mitogen-activated protein kinase kinase 4/c-Jun N-terminal kinase pathway activation during hemostatic responses. Surprisingly, under hyperlipidemic conditions, TNIK deficiency accelerated thrombosis and enhanced platelet responses to oxidized low-density lipoprotein. In this context, TNIK specifically bound to protein kinase C ε and suppressed the NADPH oxidase 2/reactive oxygen species/extracellular signal-regulated kinase 5 pathway, thereby inhibiting excessive platelet activation. We conclude that TNIK functions as a molecular switch in platelets, promoting normal hemostasis while simultaneously preventing hyperlipidemia-associated thrombosis through distinct signaling pathways. This dual regulatory mechanism provides insight into how platelets balance hemostatic function with pathological thrombosis risk and identifies TNIK as a potential therapeutic target in metabolic thrombotic disorders.

Alzheimer's disease (AD) and osteoporosis are common age-related degenerative diseases. Emerging evidence suggests that amyloid-β (Aβ) deposition may contribute to the pathogenesis of both conditions. This study investigated whether probucol could alleviate AD-associated bone loss and Aβ42-induced osteoblast dysfunction, and further explored the underlying mechanisms. Female mice were divided into four groups (n = 5 per group): C57BL/6 wild-type (WT), WT treated with probucol (WT + PBC), APP/PS1 transgenic (AD) mice, and AD treated with probucol (AD+PBC). Bone mineral density (BMD) was assessed by micro-CT. Levels of pro-inflammatory cytokines (IL-1β, IL-6, TNF-α) along with bone metabolism markers including fibroblast growth factor 23 (FGF23), sclerostin, and brain-derived neurotrophic factor (BDNF) in bone and brain tissues were measured by ELISA. FOXO3a was knocked down in the bone marrow of APP/PS1 mice via stereotactic injection of lentiviral vectors. Expression of APP and FOXO3a in bone tissue was evaluated using RT-qPCR and Western blotting (WB). Mitochondrial damage in osteoblasts and neuronal cells was assessed by transmission electron microscopy (TEM). In vitro study, osteoblast differentiation and mineralization deficits were evaluated using Alizarin Red staining. WB was used to measure the expression of AKT, FOXO3a, autophagy and apoptosis related proteins. Probucol attenuated bone loss and mitochondrial damage in both APP/PS1 and FOXO3a-knockdown APP/PS1 mice, and improved cognitive impairment and neuronal ultrastructure in APP/PS1 mice. Furthermore, probucol attenuated Aβ42-induced osteoblast differentiation and mineralization via the AKT/FOXO3a signaling pathway in vitro. These findings demonstrate that probucol ameliorates AD-associated bone loss and Aβ42-induced osteoblast impairments by regulating AKT/FOXO3a signaling pathway. Show less

A health-promoting lifestyle involves increasing health awareness and actively adopting healthier habits. For women with osteopenia, becoming more aware of osteoporosis prevention and taking positive preventive actions can effectively improve health outcomes. This study employed latent profile analysis (LPA) to assess the potential categories of healthy lifestyle promotion for women at high risk of primary osteoporosis. It aimed to identify high-risk subgroups, analyze differences and influencing factors among these groups, and offer evidence-based guidance for clinical nursing practice. From December 2024 to July 2025, women were recruited using convenience sampling from endocrine outpatient departments and physical examination centers at two Grade A tertiary hospitals in Guiyang City. Data collection followed the planned time frame, and only eligible samples were included. Latent profile analysis was performed with Mplus 8.3, and univariate and multiple logistic regression analyses were conducted using SPSS 27.0. A total of 340 valid questionnaires were analyzed. Participants were categorized into three latent profiles: the low self-management-ineffective health behaviors group (28.8 %), the moderate self-management-average health behaviors group (45.3 %), and the high self-management-favorable health behaviors group (25.9 %). These findings highlight disparities in the adoption of healthy lifestyles among women at high risk of primary osteoporosis. In clinical practice, nurses help patients with low health management recognize and overcome cognitive biases, use healthcare resources appropriately, and understand the importance of bone health. For patients with moderate health management, the can suggest exercise in addition to calcium supplementation. For those with high self-management, nurses can support their social networks to help maintain healthy behaviors over time. Show less

This first-in-human Phase I study evaluated the safety, tolerability, pharmacokinetics (PK) and pharmacodynamics (PD) of KN069, a novel dual Glucagon-like peptide-1 receptor agonist (GLP-1RA)/Glucose-dependent insulinotropic polypeptide receptor (GIPR) antagonist in Chinese men with overweight/obesity. This randomised, double-blind trial included a single ascending dose (SAD; 12-120 mg, N = 36, 3:1 active-to-placebo) and a multiple ascending dose (MAD; N = 12, dose escalation 15-60 mg) phase. Safety was assessed via adverse events (AEs) and compliance. PK was analysed using a sandwich enzyme-linked immunosorbent assay (ELISA) for Intact and Total KN069. PD included measurements of body weight, waist circumference, body mass index (BMI) and metabolic parameters. Immunogenicity was assessed by detecting anti-drug antibodies (ADA). KN069 was well tolerated, with predominantly mild-to-moderate gastrointestinal adverse events. PK showed dose-proportional exposure (12-90 mg) with a long half-life for Total KN069 (899.74-1099.01 h). In the SAD part, preliminary dose-dependent weight reductions were observed, with maximum early changes at Day 7 (90 mg: -4.71% vs. placebo: -0.41%) and sustained for up to 133 days. In the MAD part, Group B (60 mg) achieved a -2.57% mean weight reduction from baseline at Day 25, alongside a significant decrease in waist circumference (p = 0.0446). Metabolic improvements included lower fasting glucose, triglycerides, uric acid and elevated insulin/C-peptide. KN069 exhibits favourable safety, long-acting PK and preliminary dose-dependent weight reduction alongside expected pharmacologic metabolic effects, supporting further clinical development. gov Identifier: NCT06547775.

We recently showed that METRNL (Meteorin-like) protects against atherosclerosis. However, the mechanism for METRNL in atherosclerosis is largely unclear. This study aimed to demonstrate the relative importance of endothelial METRNL in atherosclerosis by comparing the effects of whole-body METRNL deficiency to endothelial-specific deficiency, and to show the subcellular distribution of endothelial METRNL and its role in mitochondrial homeostasis against atherosclerosis. Our study demonstrated that a deficiency in either endothelial or global METRNL exacerbated atherosclerosis to a similar degree in both spontaneous (age-related) and high fat diet-induced atherosclerosis, suggesting that endothelial METRNL is pivotal in the progression of atherosclerosis due to METRNL deficiency. Endothelial METRNL was diffusely distributed in the cytoplasm with subcellular localization to mitochondria, nucleus, endoplasmic reticulum, and Golgi apparatus (especially enriched in mitochondria and nucleus).

Atherosclerotic cardiovascular disease is a leading cause of morbidity and mortality worldwide, and an urgent need exists to discover new therapeutic strategies. Isolinderalactone (ISO) is a sesquiterpene compound derived from the Lindera aggregata root with significant anti-inflammatory effects. Given that atherosclerosis (AS) is a chronic inflammatory condition, the efficacy and mechanism of ISO on atherosclerotic disease are still unclear. The study aims to evaluate the therapeutic potential of ISO as an NLRP3 inhibitor in the management of AS. For in vivo study, ApoE Our data show that ISO reduced atherosclerotic plaque formation by inhibiting NLRP3 inflammasome activation and inflammatory responses. Network pharmacology analyses showed that ISO might alleviate AS by suppressing the NOD-like receptor (NLR) pathway, leading to reduced inflammatory mediators. ISO dose-dependently suppressed IL-1β secretion through inhibiting NLRP3 inflammasome activation, displaying an IC Collectively, ISO emerges as a novel NLRP3 inhibitor and a potential therapeutic candidate for atherosclerotic disease.

Lipoprotein(a) [Lp(a)] and diabetes mellitus (DM) are independent risk factors for worse outcomes in coronary artery disease (CAD) patients. Evidence of their joint association is limited. We aimed to investigate the combined effect of elevated Lp(a) and DM on survival outcomes in CAD patients. This study included 65 547 CAD patients (62.6 ± 10.7 years, 27.7% female) from CIN-II and RED-CARPET cohorts. Patients were stratified into four groups by Lp(a) levels (< or ≥ 30 mg/dL) and DM status. Multivariable Cox regression models estimated associations with cardiovascular and all-cause mortality, examining additive and multiplicative interactions. During a median follow-up of 5.5 years, 10 686 (16.3%) patients died from all causes and 5106 (7.8%) died from cardiovascular causes. Patients with Lp(a) ≥ 30 mg/dL and DM were independently associated with cardiovascular mortality (adjusted hazard ratio [aHR]: 1.28, 95% CI: 1.20-1.35; aHR: 1.53, 95% CI: 1.44-1.62, all p < 0.001, respectively). Compared to patients with Lp(a) < 30 mg/dL without DM, the aHRs were 1.26 (95% CI: 1.16-1.36, p < 0.001), 1.51 (95% CI: 1.40-1.62, p < 0.001) and 2.00 (95% CI: 1.83-2.18, p < 0.001) for those with Lp(a) ≥ 30 mg/dL without DM, Lp(a) < 30 mg/dL with DM and Lp(a) ≥ 30 mg/dL with DM, respectively. Significant additive interaction between elevated Lp(a) and DM on cardiovascular mortality was observed, with 12% of the excess risk attributed. Similar associations were observed in all-cause mortality. In patients with CAD, elevated Lp(a) and DM act synergistically to increase the risk of cardiovascular and all-cause mortality, suggesting that both risks should be considered to integrate management.

Ulcerative colitis (UC) is characterized by chronic colonic mucosal inflammation, with its pathogenesis involving multidimensional interactions and limitations in clinical treatment. Dietary restriction (DR) is a commonly used approach for UC patients to alleviate symptoms, and exploring the role of DR-related genes in UC could provide new directions for the development of precision therapies. Bioinformatics analysis was performed on UC-related datasets (GSE75214, GSE73661) obtained from the GEO database. Candidate genes were acquired by intersecting differentially expressed genes (DEGs) with dietary restriction-related genes (DRRGs). Subsequently, key genes were identified via machine learning algorithms and ROC curve analysis. A deep neural network (DNN) model and a diagnostic nomogram were constructed. In addition, gene set enrichment analysis (GSEA), gene set variation analysis (GSVA), immune infiltration analysis, and single-cell RNA sequencing (scRNA-seq) analysis were conducted. Finally, the expression of key genes was validated through experiments. CPT1A, ANGPTL4, and CLDN1 were identified as the key genes. The deep neural network (DNN) model achieved area under the curve (AUC) values of 0.914 and 0.933 in the two datasets, respectively; the diagnostic nomogram exhibited high predictive performance (AUC > 0.7), and decision curve analysis (DCA) revealed its potential clinical net benefit. Enrichment analyses demonstrated that the key genes were significantly enriched in dietary restriction (DR)-related pathways, including cytokine-receptor interaction, the IL2-STAT5 signaling pathway, and fatty acid metabolism. Thirty-two activated pathways and five inhibited pathways were detected in UC patients (e.g., the oxidative phosphorylation pathway was suppressed). Immune infiltration analysis identified 27 differentially infiltrating immune cell types. CLDN1 was localized to epithelial cells, ANGPTL4 to fibroblasts, and CPT1A to endothelial cells. Macrophages were identified as a signaling hub in UC, showing intensified crosstalk with stromal and vascular cells via pathways such as ACKR1. Experimental validation confirmed that ANGPTL4 and CLDN1 were highly expressed in UC, whereas CPT1A was lowly expressed, a pattern consistent with the expression trends observed in public database analyses. These results indicated that CPT1A, ANGPTL4, and CLDN1 are involved in the pathological regulation of UC by DR through modulating the metabolism-immune-barrier axis, providing novel biomarkers and potential intervention targets for the clinical diagnosis and targeted therapy of UC.

To develop and validate a prediction model for in-hospital cardiogenic shock (CS) after percutaneous coronary intervention (PCI) in patients with acute myocardial infarction (AMI) based on machine learning (ML) algorithms. A total of 1608 AMI patients admitted to the First Hospital of Lanzhou University during 2023 and 2024 were retrospectively enrolled in this study. The 851 patients from 2023 were randomly divided into a training set ( LASSO regression initially identified 13 candidate features, while the random forest (RF) model demonstrated the best predictive performance in the training set. Following Boruta refinement, seven key features were retained, leading to the construction of an updated RF model. This model achieved an AUROC of 0.906, an accuracy of 0.977, a precision of 0.900, a sensitivity of 0.643, a specificity of 0.996, and a F1 score of 0.750 on the internal validation set. Temporal external validation at the same center showed an AUROC of 0.988, an accuracy of 0.967, a precision of 0.701, a sensitivity of 0.904, a specificity of 0.972, and a F1 score of 0.790. Furthermore, the model demonstrated excellent calibration, with a Brier score of 0.023 and 0.027. The SHAP analysis ranked feature importance as Killip class, D-dimer (DD), creatinine (Crea), alanine aminotransferase (ALT), apolipoprotein B/A (APOB/A), diastolic blood pressure (DBP) and lactate (Lac). We developed and validated a RF model based on seven key variables—Killip class, DD, Crea, ALT, APOB/A, DBP and Lac—that serves as a predictive tool for identifying the risk of in-hospital CS in AMI patients post-PCI. Additionally, we created an online prediction application using Streamlit, which facilitates the implementation of this model into clinical practice. Show less

The present study aimed to investigate the combined impact of lipoprotein (a) [Lp(a)] and low-density lipoprotein (LDL) subfractions on cardiovascular outcomes in patients with acute coronary syndrome (ACS). The study enrolled 2061 ACS patients from Tianjin Chest Hospital. Participants were categorized into 4 groups based on their Lp(a) and the concentration of the sixth component particles of LDL(LDL-P6). The primary endpoint was the occurrence of major adverse cardiovascular events (MACE). The relationship between LDL-P6, Lp(a), and MACE was evaluated. Over a mean follow-up period of 5.4 years, 456 (22.1%) patients experienced MACE. Multivariate analysis identified both LDL-P6 and Lp(a) as significant independent predictors of MACE in ACS patients. Those in the highest-risk group had a substantially higher incidence of MACE compared with the lowest-risk group (HR 5.718; 95% CI 3.703-8.829; Show less

Retigabine (RTG) shows notable neuroprotective efficacy in multiple brain injury models; however, its interplay with endoplasmic reticulum stress (ERS) is poorly understood. This study was designed to explore the therapeutic potential of RTG against CRS-induced depression-like behaviors and cognitive deficits in mice and to uncover the associated molecular mechanisms. A depression-like and cognitive impairment model was established in C57BL/6 male mice using chronic restraint stress (CRS). Six-week-old C57BL/6 male mice were randomly assigned to the following groups: control (Con), model (CRS), RTG (10 mg/kg), XE-991 (2 mg/kg) or tunicamycin (Tm, 2 mg/kg). Behavioral tests were conducted to assess depression-like behaviors and cognitive function. Hippocampal neuronal morphology was examined by H&E and immunofluorescence staining, while changes in endoplasmic reticulum stress (ERS)-related signaling pathways were analyzed by Western blot. Retigabine treatment reduced hippocampal neuronal damage and the expression of ERS-related factors (GRP78, CHOP) and the pro-apoptotic factor BAX in CRS-induced mice, while it increased the levels of BDNF. These effects were antagonized by XE-991 and the ERS agonist tunicamycin (Tm). Retigabine may alleviate CRS-induced depressive-like behaviors and cognitive impairment by inhibiting ERS-mediated apoptosis, suggesting its potential as a novel therapeutic strategy for depression.
