Hemodynamic abnormalities within atherosclerotic plaque regions, particularly localized high shear stress and endothelial dysfunction, present novel targets for intervention by drug delivery systems. In this study, we designed a polysaccharide-based carrier (HF-AF) from fucoidan, featuring a dynamic supramolecular structure. A dynamic supramolecular network was established within this carrier via dynamic supramolecular interactions between hydroxypropyl-β-cyclodextrin and adamantane-methylamine. The anti-inflammatory compound tilianin, formulated into nanocrystals (Til NCs), was then encapsulated to create a shear-responsive nanosystem (HF-AF@Til NCs). The system's primary therapeutic strategy is its response to pathological hemodynamic forces: upon encountering high shear stress at a stenosis, the supramolecular network undergoes dissociation, triggering a mechanically-gated release of the encapsulated Til NCs. This shear-triggered function is complemented by the natural P-selectin affinity of the fucoidan backbone, which facilitates the anchoring of the nanocarrier at the inflamed lesion site. This sophisticated "anchor-and-release" mechanism enables superior drug accumulation precisely at plaque sites. In ApoE Show less

Given the limitations of current treatments for Alzheimer's disease (AD), this study aims to comprehensively evaluate the therapeutic efficacy of human umbilical cord mesenchymal stem cells (hUCMSCs) in AD mouse models through a systematic review and meta-analysis. Additionally, we explore the impact of transplantation dose and route on treatment outcomes to identify the optimal window for clinical application. In accordance with the PRISMA guidelines, we systematically searched four major databases to identify randomized controlled trials involving hUCMSCs in AD mouse models. We used the standardized mean difference (SMD) to synthesize effect sizes and performed subgroup analyses based on pre-defined transplantation routes and doses. A total of 13 studies were included in the analysis. The meta-analysis revealed that hUCMSCs transplantation significantly improved spatial learning and memory in AD model mice, with a marked reduction in escape latency (SMD = -2.55; 95% CI: -3.34 to -1.75; Human umbilical cord mesenchymal stem cells can improve behavioral and pathological outcomes in AD mouse models via multiple mechanisms of action. The intravenous route using medium to high doses emerges as a critical factor for achieving optimal effects, providing important evidence and informing future experimental design and clinical translational research.

Timosaponin AIII (Tim-AIII), a steroidal saponin derived from Anemarrhena asphodeloides, has emerged as a promising antitumor agent, yet its precise molecular targets and mechanisms in breast cancer remain poorly defined. Here, we identify fibroblast growth factor 2 (FGF2) as a direct binding target of Tim-AIII using a combination of network pharmacology, CETSA, and surface plasmon resonance assays. Mechanistically, Tim-AIII exhibits a dual therapeutic mode of action. First, it induces reactive oxygen species (ROS)-mediated endoplasmic reticulum (ER) stress, activating the eIF2α-ATF4-CHOP axis and initiating apoptosis. Second, it dampens the FGF2-FGFR1-PI3K/AKT signaling cascade, thereby inhibiting epithelial-mesenchymal transition (EMT) and suppressing cell migration and invasion. RNA sequencing and enrichment analyses confirm that Tim-AIII regulates critical oncogenic pathways, including ER stress, calcium signaling, and PI3K/AKT. In vivo evaluations demonstrate that Tim-AIII significantly reduces tumor growth without detectable systemic toxicity in breast cancer-bearing mice. This study not only elucidates the molecular basis of Tim-AIII's antitumor efficacy but also positions it as a potential targeted therapeutic for breast cancer, with dual action on ERS-induced apoptosis and EMT suppression.

Atherosclerotic cardiovascular disease remains the leading cause of global mortality, with hypercholesterolemia serving as a critical driver of atherogenesis. Although current lipid-lowering therapies substantially improve circulating lipid profiles, strategies that provide more durable, safe, and efficient control of lipid metabolism are still needed. Epigenome editing offers a promising approach for long-lasting repression of disease-modifying genes without altering the underlying DNA sequence. Here, we develop CRISPRoff platforms delivered by adeno-associated virus or lipid nanoparticle to epigenetically silence hepatic Hmgcr or Pcsk9 in vivo. In both C57BL/6J wild-type and ApoE Show less

The repair mechanisms following sciatic nerve injury involve complex signaling interactions between neurons and microglia. Recent studies have demonstrated that neurons activate microglia by releasing chemokines, glutamate, and neurotrophic factors. In turn, microglia regulate neuronal survival and regeneration via phagocytosis, phenotypic switching, and secretion of growth factors. However, the spatiotemporal diversity of signaling pathways, metabolic regulation of the microenvironment, and barriers to clinical application remain inadequately addressed. This review provides a comprehensive analysis of morphological and functional changes in neuronal cell bodies and of the activation and regulatory mechanisms of microglia after sciatic nerve injury. It highlights the dynamic interaction network encompassing the ATP-P2X7 signaling pathway, the CX3CL1- CX3CR1 pathway, the CCL2-CCR2 chemokine axis, the BDNF-TrkB pathway, and inflammatory mediators, offering novel insights into precision therapeutic strategies targeting neuron-glial interactions.

Individuals with prediabetes or diabetes face elevated dementia risk, yet robust prediction tools and mechanistic insights remain limited. This study aimed to develop and validate a protein-based risk score for dementia prediction in this high-risk population while elucidating underlying biological pathways and therapeutic targets. Utilising data from 10 433 UK Biobank participants with prediabetes or diabetes and proteomic profiling (2911 plasma proteins measured), we developed a dementia protein risk score in a training set ( In the training set, 23 out of 2911 proteins were selected. In the testing set, compared with the basic model (age and sex, C-index: 0.78; 95% confidence interval [CI] 0.74-0.82), the dementia protein risk score (C-index: 0.84; 95% CI 0.81-0.88) significantly improved the performance in predicting incident dementia (C-index increase: 0.06; 95% CI 0.02-0.12), while cardiovascular risk factors, ageing and dementia incidence risk factors (C-index: 0.80; 95% CI 0.76-0.83) and apolipoprotein E (APOE; age and sex included, C-index: 0.81; 95% CI 0.77-0.85) had no significant improvement. Six key proteins (glial fibrillary acidic protein [GFAP], neurofilament light polypeptide [NEFL], Brevican core protein [BCAN], protein MENT [MENT], APOE and growth/differentiation factor 15 [GDF15]) captured the most predictive power. Pathway analyses implicated extracellular matrix remodelling and cholesterol metabolism, whereas Mendelian randomisation identified causal roles for APOE, haematopoietic prostaglandin D synthase (HPGDS), BAG family molecular chaperone regulator 3 (BAG3) and GDF15. Nine proteins were prioritised as druggable targets, including HPGDS, with existing Food and Drug Administration-approved drugs. This study establishes a highly accurate protein-based risk score for dementia prediction (including 6-23 proteins) in individuals with prediabetes or diabetes, uncovering actionable biological pathways and therapeutic targets. The findings enable precision risk stratification and accelerate translational opportunities for dementia prevention in this population. Show less

Alzheimer's disease (AD) is a progressive neurodegenerative disorder characterized by irreversible cognitive decline and synaptic dysfunction and represents the most prevalent etiology of dementia, accounting for an estimated 60-70% of all clinically diagnosed cases worldwide. The growing focus on microglia-neuron interactions in AD research highlights their diverse, region-specific responses, which are driven by the functional and pathological heterogeneity across different brain regions. Therefore, investigating the interactions between microglia and neurons is of crucial importance. To explore the regional heterogeneity of microglia-neuron crosstalk in AD, we integrated human single-nucleus RNA sequencing data from the prefrontal cortex (PFC), hippocampus (HPC), and occipital lobe (OL) provided by the ssREAD database. Our study delineated four microglial subtypes and uncovered a pseudotime trajectory activation trajectory leading to the disease-associated microglia (DAM) phenotype. The transition along this trajectory is driven and stabilized by a key molecular switch: the coordinated downregulation of inhibitory factors (e.g., LINGO1) and upregulation of immune-effector and antigen-presentation programs, which collectively establish the pro-inflammatory DAM state. Furthermore, we observed that each brain region displayed unique microglia-neuron communication patterns in response to AD pathology. The PFC and OL engage a THY1-ITGAX/ITGB2 signaling axis; the HPC predominantly utilizes the PTPRM pathway. Notably, THY1 dysregulation strongly correlates with pathology in the PFC, HPC, and OL, suggesting that microglia-neuron crosstalk in AD possesses both heterogeneity and commonality. The main contribution of this study is the systematic characterization of region-specific microglia-neuron interactions and the identification of THY1 as a potential mediator that may be targeted therapeutically to modulate microglial function in affected brain regions.

Glycolysis-derived lactate serves as a substrate for lysine lactylation, an epigenetic modification playing critical transcriptional regulatory roles in inflammatory diseases. Endothelial inflammation, characterized by upregulated glycolysis, initiates atherosclerosis, yet the contribution of histone lactylation remains undefined. Although narciclasine exhibits anti-inflammatory and antioxidant properties, its impact on endothelial inflammation in atherosclerosis is unknown. Connectivity Map (CMap) analysis predicted narciclasine as an inhibitor of oscillatory shear stress and TNF-α-induced endothelial inflammation. In vitro, treatment of human umbilical vein endothelial cells (HUVECs) with 20 nM narciclasine significantly suppressed ox-LDL-induced expression of VCAM1, ICAM1, SELE, and CCL2, reduced reactive oxygen species (ROS) production, and inhibited monocyte adhesion and migration. In vivo, administration of narciclasine (0.02 mg/kg) attenuated carotid artery endothelial inflammation and macrophage infiltration, consequently reducing early atherogenesis in partial carotid ligation model in ApoE Show less

This study evaluates plasma-based proteomic profiles for predicting amyloid positivity in adults with Down syndrome (DS) and examines the impact of apolipoprotein E ε4 (APOE ε4) on test performance. Cross-sectional data from 290 adults with DS were analyzed using single molecule array (SIMOA) technology to measure plasma amyloid beta (Aβ)42, Aβ40, neurofilament light chain (NfL), glial fibrillary acidic protein (GFAP), tau phosphorylated at threonine 181, and total tau. Amyloid burden was quantified using Pittsburgh Compound B and (18)F-florbetapir Aβ positron emission tomography. Support vector machine analyses were conducted with biomarkers as predictors and age, sex, and APOE ε4 carrier status as covariates. Age, GFAP, and NfL contributed the most to the model performance. The proteomic profile achieved an area under the curve (AUC) of 96% in models with and without APOE ε4. These findings suggest that plasma proteomic biomarkers can effectively identify amyloid positivity in adults with DS and may support clinical triage, monitoring, and selection for clinical trials, independent of APOE ε4 status.

Atherosclerosis is a chronic and progressive inflammatory disease that can lead to adverse cardiovascular and cerebrovascular events. Phenotypic switching of vascular smooth muscle cells (VSMCs) plays a pivotal role in its development and progression, but the upstream regulatory mechanisms remain incompletely defined. Here, we identify ubiquitin-fold modifier 1 (UFM1), a ubiquitin-like protein, as a critical regulator of VSMCs plasticity and atherogenesis. In VSMCs stimulated with oxidized low-density lipoprotein (ox-LDL), UFM1 overexpression markedly attenuated phenotypic switching, restoring contractile features and suppressing synthetic activation, accompanied by reduced proliferation and migration. In contrast, UFM1 knockdown further exacerbated these phenotypic alterations. In ApoE Show less

The impact of obstructive sleep apnea (OSA) on subsequent cardiovascular events in patients with acute coronary syndrome (ACS) remains debated. This study aims to investigate whether the association of OSA with cardiovascular events is affected by lipoprotein (a) [Lp(a)] levels. This is a sub-analysis of prospective cohort study (OSA-ACS, NCT03362385) enrolled ACS patients. OSA defined as an apnea-hypopnea index ≥15 events/h. The effects of OSA on subsequent cardiovascular outcomes were evaluated across varying Lp(a) thresholds. Coronary plaque features by coronary computed tomography angiography were also analyzed. A total of 1137 patients were enrolled, 608 patients (53.5%) were diagnosed with OSA. At a median follow-up of 3.6 years, OSA was associated with a higher risk of major adverse cardiovascular and cerebrovascular events (MACCE) in patients with Lp(a) level > median (HR 1.59, 95% CI 1.12-2.26, p=.009), but not in patients with Lp(a) level ≤ median (HR 1.09, 95% CI 0.80-1.49, p=.60). There were consistent increases in HRs for MACCE in the OSA group with Lp(a) levels rising, as stratified by tertiles or quartiles of Lp(a). In patients with Lp(a) level > median, OSA demonstrated a higher prevalence of ≥1 high-risk plaque (HRP) feature (51.4% vs. 33.3%, p=.03) and low-attenuation plaque (50.0% vs. 32.8, p=.04) per vessel than non-OSA. OSA was associated with a continuously increased cardiovascular risk and a higher prevalence of HRP features as Lp(a) levels rose. Lp(a) may help identify ACS patients at higher cardiovascular risk, in whom the efficacy of OSA treatment should be further investigated. Show less

Endometrial carcinoma (EC) is a common malignancy of the female reproductive system. Rab35 is widely recognized as an oncogenic driver and has been implicated in the progression of various malignant tumors. However, its regulatory mechanism and pathobiological roles in EC remain unclear. Rab35 expression in EC was systematically profiled via integrative analysis of clinical endometrial specimens and multi-omics databases (CPTAC and GEO). The association between clinical prognosis and Rab35 expression was examined using Kaplan-Meier analysis. Mechanistic investigations included transwell assays, western blotting, and immunofluorescence in Rab35-overexpressing and CRISPR/Cas9-mediated Rab35-knockout EC cells. A mouse xenograft tumor model was established to confirm the effects of Rab35 in vivo. The Rab35 content increased gradually from normal endometrium to atypical hyperplastic endometrium to EC. Moreover, the findings indicated that elevated Rab35 expression was significantly associated with advanced disease characteristics and poor overall survival in patients with EC. In addition, Rab35 enhanced the migratory and invasive nature of EC cells. The expression of Rab35 was inversely linked to that of the β-catenin destruction complex-related proteins Axin-1 and GSK3β, leading to the increased nuclear translocation of β-catenin in EC cells. Animal experiments further verified that Rab35 augmented EC progression by regulating the nuclear translocation of β-catenin. The study revealed that high expression of Rab35 was strongly correlated with EC progression and a poor clinical outcome. Furthermore, Rab35 promoted EC cell metastasis by accelerating the nuclear translocation of β-catenin. These findings suggest that Rab35 serves as a valuable biomarker and therapeutic target for EC.

Acute alcohol consumption is known to exert widespread physiological effects, yet the immediate impacts on metabolic biomarkers remain incompletely understood. The present randomized controlled trial was conducted to investigate the acute effects of a single episode of alcohol ingestion on various biomarkers in healthy individuals. A total of 45 male participants were recruited and randomized into an alcohol group (n = 40) and a control group (n = 5) at an 8:1 ratio. Volunteers in the alcohol group ingested 40% Absolut vodka within 15 min. Blood pressure, heart rate, and blood oxygen saturation were measured at 0 h, 1 h, 3 h, 5 h, 12 h, and 24 h. Venous blood samples were drawn at 0 h, 1 h, 5 h, 12 h, and 24 h after alcohol intake. Our results showed that levels of liver function markers, including α-fucosidase (AFU), albumin (ALB), and alkaline phosphatase (ALP), were significantly increased in the alcohol group compared to the control group. The 24-h area under curve (AUC) of AFU, ALB, and ALP were significantly higher in the alcohol group. The liver fibrosis maker collagen type Ⅳ (Ⅳ-C) tended to be higher at 1 h and 12 h in the alcohol group compared to the control group. Lipid levels, including triglycerides (TG), apolipoprotein A1 (APOA1), and the APOA1/APOB, were significantly elevated after alcohol ingestion, particularly at 5 h and 12 h. The 24 h-AUC of TG, APOA1, and APOA1/APOB were higher in the alcohol group than in the control group. Additionally, cardiac function indicators, including heart rate, systolic blood pressure (SBP), and diastolic blood pressure (DBP), were significantly elevated in the alcohol group. SBP and DBP remained higher 24 h after alcohol ingestion compared to the control group. This study demonstrated that even a single episode of binge drinking could induce significant alterations of biomarkers related to liver function, cardiac function, and lipid profiles. These findings provided valuable insights into the short-term impact of alcohol on health and highlighted the importance of further research to explore the long-term implications of repeated acute alcohol exposure. Given the very small control group, these results should be interpreted as preliminary and confirmed in larger, more balanced randomized trials.

With the widespread use of smartphones among adolescents, smartphone addiction has become a growing mental health concern. Adolescents' limited self-regulation makes them particularly vulnerable to using smartphones to escape real-life stress, heightening addiction risk. However, the heterogeneity of addictive behaviors and the dynamic role of experiential avoidance have been underexplored. This 6-month longitudinal study surveyed 547 Chinese primary and secondary students using the Smartphone Addiction Scale (SAS) and the Acceptance and Action Questionnaire-II (AAQ-II). Latent profile analysis (LPA) and latent transition analysis (LTA) were applied to identify subgroups and examine transitions between these subgroups. Cross-lagged panel network analysis (CLPN) revealed key symptom interactions between experiential avoidance and addiction. The study identified two addiction subgroups: a stable "low-risk group" (84.9 percent) and a "high-risk group," 51.4 percent of whom transitioned to low risk over time. Logistic regression showed that experiential avoidance significantly predicted high-risk membership (odds ratios [OR] = 1.083-1.102) and deterioration within the low-risk group (OR = 1.036). The CLPN identified "online intimacy" (SPA-3) and "hesitation and overcautious" (EA-7) as driver nodes, with "withdrawal symptoms" (SPA-2) serving as a central node. These findings emphasize the crucial role of experiential avoidance in adolescent smartphone addiction and suggest symptom-level targets for early intervention. The results support acceptance and commitment therapy (ACT) as a promising approach for reducing smartphone addiction among youth. Show less

Elucidating effective components and mechanisms of traditional Chinese medicine (TCM) formulas remains a critical challenge for modernization. ErShiWei RouDouKou Pills (ESWRDK), a Tibetan formula with cardiovascular potential, lacks systematic exploration of its anti-atherosclerotic (AS) material basis and mechanisms. A novel six-stage cascade focused strategy integrating three-dimensional filtering mode, qualitative characterization, multi-component quantification, anti-AS efficacy, multi-lipidomics and bioactive compounds evaluation was proposed, advancing TCM research by holistic and multi-layered approach. UHPLC-MS combined with mass defect-ion intensity filtering (MD-ITF), DPIs, Nl and FBMN employed for profiling. Nine characteristic components were quantitated. A 12-week high-fat diet was fed to ApoE Firstly, the MD-ITF method and structural classification was established for complicated matrix. Secondly, 426 chemical components including 74 low-abundance were characterized. Thirdly, 9 characteristic components were quantified, and content distribution were profiled. Fourthly, ESWRDK reduced lipids, inflammation, and aortic plaques in AS mice. Fifthly, a total of 38, 23 and 48 differential biomarkers were identified predominantly linked to glycerophospholipids (GP) metabolism. WB confirmed ESWRDK downregulated hepatic PLA2, upregulated p-AMPK/AMPK and PPAR-α, and suppressed SREBP-1, orchestrating and mitigating lipid dysregulation. Finally, dehydrodiisoeugenol and agarotetrol bound PLA2, formed stable 1:1 static quenchingand inhibited PLA2 activity in vitro. A novel six-stage cascade-focused strategy was successfully established to elucidate ESWRDK's anti-AS mechanisms, offering feasible paradigm for advancing modernization of TCM. Show less

Aging worsens Alzheimer's disease (AD) peripheral metabolism and central pathology, yet few interventions are effective when started late. Methionine restriction (MR) induces the hepatokine FGF21 and may protect brain function, but its efficacy and mechanisms when started late are unclear. Fourteen-month-old male APP/PS1 mice received 17 weeks of MR (0.17% methionine); behavioral, histological, and molecular assays were performed and hippocampal FGFR1 was knocked down by adeno-associated virus. Late-life MR improved peripheral glucose/lipid profiles, reduced Aβ deposition, preserved synaptic markers, and suppressed neuroinflammation. MR-induced hepatic FGF21 and brain FGFR1-AMPKα signaling to inhibit NFκB; hippocampal FGFR1 knockdown abolished MR's neuroprotective effects while leaving peripheral metabolic changes intact. Even when initiated in late life, MR robustly reduces AD pathology via the hepatic FGF21-brain FGFR1 axis, independent of peripheral metabolic changes. These preclinical findings position MR and FGF21-FGFR1 axis as actionable late-life intervention targets with potential for clinical translation. Show less

We examined whether the excess cardiovascular disease (CVD) risk among adults with steatotic liver disease (SLD) subtypes could be reduced or eliminated through joint control of low-density lipoprotein cholesterol (LDL-C), lipoprotein(a) [Lp(a)], and high-sensitivity C-reactive protein (hs-CRP). This prospective cohort study included 291,995 participants from the UK Biobank, comprising 77,187 with metabolic dysfunction-associated steatotic liver disease (MASLD), 22,190 with metabolic dysfunction and alcohol-associated liver disease (MetALD), 5474 with alcohol-associated liver disease (ALD), and 187,144 without SLD. Cox proportional hazards models were used to assess CVD risk associated with numbers of LDL-C, Lp(a), and hs-CRP controlled within the target range. During 12 years of median follow-up, 24,251 CVD events were documented, with 19,661 coronary heart disease and 5600 stroke. Among individuals with various SLD subtypes, those with all three factors controlled had the lowest risks of CVD, with HRs (95% CIs) of 0.65 (0.58, 0.72) in MASLD, 0.61 (0.49, 0.76) in MetALD, and 0.57 (0.35, 0.93) in ALD when comparing to zero-factor control. In addition, among individuals with SLD subtypes achieving all three factors within target ranges, the HRs (95% CIs) of CVD were 0.97 (0.88, 1.07) in MASLD, 0.90 (0.75, 1.08) in MetALD, and 0.63 (0.42, 0.95) in ALD, as compared with non-SLD controls. Similar association patterns were observed for coronary heart disease and stroke. Participants with various SLD subtypes who had optimally controlled LDL-C, Lp(a), and hs-CRP showed no excess or even lower risk of CVD as compared with the general population. Not available.

According to existing research findings, dihydroartemisinin effectively regulates bone metabolism balance, while ferroptosis is closely related to the occurrence of steroid-induced osteonecrosis of the femoral head. As the exact biological mechanism among the three is still unclear, Mendelian randomization, computer-aided drug design, and transcriptomics sequencing were used to explore the specific mechanism of action. The study validated the specific signaling pathways through which dihydroartemisinin may treat steroid-induced osteonecrosis of the femoral head using animal experiments and transcriptomics sequencing. Data were obtained from public databases for Mendelian randomization analysis, and a two-sample Mendelian randomization was used to determine the intermediary role of core pathway-related targets. Computer-aided drug design was employed to assess the binding affinity between dihydroartemisinin and core targets. Transcriptome sequencing determined that dihydroartemisinin may treat steroid-induced osteonecrosis of the femoral head by regulating ferroptosis. We obtained 564 ferroptosis-related targets that met the analysis criteria and 1812 plasma proteins from the UK Biobank, and analyzed finngen_R11_OSTEON_DRUGS in the Finnish database as outcome. The results showed that there were two quantitative trait loci that had a causal relationship with ferroptosis targets. There were 110 protein quantitative trait loci causally associated with plasma proteins from the UK Biobank, and none of these loci had an inverse causal relationship with SONFH. Through mediation analysis, 7 mediating pathways were identified, yielding eight targets including ZP3, CCL17, APOE, C7ORF50, SPINK4, SPINK2, FTMT, and PRDX6. Computer-aided drug design revealed that CCL17 and PRDX6 exhibited the best docking effects. The study determined that CCL17 and PRDX6 have a significant causal relationship with SONFH. It also clarified the specific mechanism by which DHA may regulate ferroptosis to treat SONFH, which will provide a reference for the discussion of the prevention and treatment mechanisms of SONFH.

Consecutive T2DM patients who underwent coronary angiography (CAG) or percutaneous coronary intervention (PCI) between January 2019 and December 2021 were enrolled. Baseline Lp(a) was measured before the operation. CIN was defined as an increase in serum creatinine of more than 25% or 44 μmol within 72 h of contrast administration. The relationship between Lp(a) and CIN risk was analyzed. A total of 928 T2DM patients were included. CIN developed in 11.1% (103/928) of patients. The Lp(a) level was significantly higher in patients with CIN than in non-CIN patients (311.12 ± 278.66 vs. 254.19 ± 274.56 mg/L, A higher serum Lp(a) level indicates an increased risk of CIN in T2DM patients undergoing CAG or PCI and can serve as an independent predictor of CIN in this population.

Neuroinflammation is a key pathogenic process in multiple central nervous system (CNS) disorders. It can lead to neuronal injury and cognitive decline through excessive glial activation and aberrant engagement of the programmed cell death protein-1/programmed death-ligand 1 (PD-1/PD-L1) checkpoint axis. To address these pathologies, we engineered a PD-1-enriched macrophage-membrane, lactoferrin-modified, PEGylated, glycyrrhizic-acid-loaded biomimetic hybrid liposome (PMLpGL) for dual, precise modulation of the neuroinflammatory microenvironment. PMLpGL alleviates neuronal inhibitory signaling by reversibly sequestering excess PD-L1 via membrane-anchored PD-1, while its cargo GA suppresses high-mobility group box-1 (HMGB1)-driven inflammatory cascades, thereby returning inducible PD-1/PD-L1 expression and glial activation toward homeostasis. Physicochemical characterization showed a hydrodynamic diameter of 165 ± 3 nm and a zeta potential of -10.2 ± 0.2 mV. Engineered macrophage membranes displayed marked PD-1 overexpression, and ligand-depletion saturation assays demonstrated specific, saturable PD-1/PD-L1 binding. In a Transwell blood-brain barrier (BBB) model, PMLpGL achieved a 24-h permeability of 22.86 ± 0.14 %, indicating robust in-vitro BBB traversal. In vivo fluorescence imaging showed peak brain accumulation at 24 h with retention to 48 h; liquid chromatography-tandem mass spectrometry further confirmed brain targeting and persistence-at 12 h, brain GA with PMLpGL was ∼48-fold higher than free drug and remained quantifiable at 48 h. Pharmacodynamic evaluations in cells and mice demonstrated that PMLpGL suppresses glial activation and normalizes inducible checkpoint expression; reshapes the cytokine milieu by lowering IL-6, IL-1β, TNF-α, and HMGB1 while increasing IL-10, TGF-β, and brain-derived neurotrophic factor; and restores the synaptic protein synapsin-1. Correspondingly, PMLpGL significantly improved cognition in open-field, novel object recognition, and Morris water maze tests.

Previous research has suggested that high levels of internet use are associated with lower levels of physical activity. However, recent studies have yielded mixed findings. First, we aim to explore the prevalence of internet addiction and sedentary behavior among college students. Second, we examine the relationship between sedentary behavior and body composition. Additionally, we employ latent profile analysis (LPA) to identify subgroups of internet addiction profiles and to explore the associations between these latent profiles and sedentary behavior. This cross-sectional study examined the relationship between sedentary behavior, internet addiction, and body composition among 369 Chinese college students. Sedentary behavior was assessed via self-reported sitting time, internet addiction was measured using a standardized questionnaire, and body composition was evaluated with the InBody 120 device. LPA, an individual-centered method, was used to identify homogeneous subgroups of internet addiction. 42.3 % of students exhibited internet addiction and 72.6 % reported ≥6 h of daily sitting. LPA revealed two distinct profiles of internet addiction-"Regular" (57.2 %) and "Internet addiction" (42.8 %)-highlighting its heterogeneous nature. The findings suggest that age (p = 0.296), gender (p = 0.304), and sedentary time (p = 0.954) may not be the primary factors contributing to these profiles. Policymakers and campus health programs should tailor interventions to distinct internet addiction subgroups. Further research is needed to examine psychological, behavioral, and social contributors, as well as long-term effects. Show less

Metabolic-dysfunction associated steatohepatitis (MASH) arises from sustained triglyceride overload of the intestine-liver axis, yet current therapies rarely coordinate intestinal lipid entry with hepatic triglyceride disposal. Here we identify a phenolic-acid fraction as a dual-compartment metabolic modulator that couples intestinal lipase inhibition to CPT1α-PPARα-dependent hepatic β-oxidation across species. Across species, we investigated the kinetics and metabolic actions of a phenolic fraction (PhAM) using recombinant lipase systems, epithelial transport assays, hepatocyte models, pharmacokinetics, diet-induced metabolic disease paradigms, quantitative histopathology, and a 24-week randomized placebo-controlled clinical trial. PhAM selectively suppresses pancreatic and intestinal lipases non-competitively, lowering V_max with minimal K_m change, resembling some features of orlistat, but via a distinct, non-covalent mechanism. In Caco-2 monolayers and ex vivo loops, it reduces apical-to-basolateral fatty-acid flux, depletes intracellular triglycerides, and limits luminal-to-plasma lipid transfer. PhAM is orally bioavailable, with measurable plasma exposure and prolonged intestinal residence. Under high-fat feeding, it increases fecal fat loss, attenuates post-lipid-load triglyceride excursions, and lowers hepatic triglycerides without altering ApoB secretion. Its triglyceride-lowering effect requires CPT1α-dependent mitochondrial import and PPARα activation, elevates β-hydroxybutyrate, and induces oxidative genes while sparing lipogenesis. In chronic MASH, PhAM reduces steatosis, ballooning, inflammation, and metabolic-dysfunction associated steatotic liver disease (MASLD) Activity Score. A 24-week clinical subgroup, defined by ultrasound and transaminase enrichment, showed dose-responsive improvements in ultrasonographic steatosis and metabolic biomarkers. Collectively, these findings define PhAM as a phenolic-acid-based agent that aligns intestinal lipid restriction with hepatic oxidative unloading, offering a mechanistically coherent framework for potentially addressing steatotic liver disease-associated metabolic features.

To investigate the association between vaginal microbiota structure in early pregnancy and gestational diabetes mellitus (GDM) and to characterize microbial signatures for early screening for GDM. The present study was a nested case-control study recruiting pregnant women from the Nanjing Gulou Maternal-Child Health Center, China. Vaginal swabs were collected before 20 weeks of gestation for 16S rRNA sequencing. Following 1:3 propensity score matching, 45 GDM cases and 135 controls were enrolled. The final analysis included 42 GDM cases and 121 controls. A random forest model was used to explore the genera of vaginal differential microbiota associated with GDM. Based on these findings, latent profile analysis (LPA) was conducted to explore potential types of vaginal microbiota, and logistic regression was used to analyze the association between vaginal microbiota types and GDM. The GDM group exhibited elevated alpha diversity (Chao1 index, The composition and structure of vaginal microbiota in early pregnancy are different in the two groups.

Endothelial cell (EC) senescence is intimately linked to the development and progression of atherosclerosis. The FGFR2 (fibroblast growth factor receptor 2) signaling is crucial in regulating the phenotype of ECs. Recent studies have revealed that cell phenotype-specific alternative splicing of FGFR2 premRNA (precursor mRNA) results in the mutually exclusive inclusion of either exon IIIb or IIIc, leading to critical differences in receptor function. This study aimed to investigate the role of FGFR2 alternative splicing in EC senescence and atherosclerosis development, and to elucidate the underlying mechanisms. Clinical samples and animal models were used to assess the association between FGFR2-IIIc isoform expression and EC senescence as well as atherosclerotic plaque formation. The mechanisms underlying FGFR2-IIIc-induced EC senescence were elucidated through a combination of in vivo and in vitro investigations. In addition, genetically engineered mice with endothelial-specific overexpression or knockdown of FGFR2-IIIc were utilized to investigate the impact of FGFR2-IIIc on vascular endothelial senescence and the progression of atherosclerosis. Elevated expression of the FGFR2-IIIc isoform was detected in clinical samples and animal models of aging and atherosclerosis, where it correlated with both EC senescence and atherosclerotic plaque formation. Mechanistically, the alternative splicing-mediated switch from FGFR2-IIIb to FGFR2-IIIc established an FGF2-FGFR2-IIIc autocrine feedback loop, which drove ECs toward a senescence-associated secretory phenotype via the PKC (protein kinase C) ε/STAT3 (signal transducer and activator of transcription) pathway. Senescence-inducing stimuli promoted the binding of the splicing factor hnRNP H1 (heterogeneous nuclear ribonucleoprotein H1) to exon IIIb of the This study reveals that FGFR2 splicing mediated by hnRNP H1 promotes EC senescence and atherosclerosis via an FGF2-FGFR2-IIIc autocrine loop. These findings identify FGFR2-IIIc as a potential therapeutic target for age-related atherosclerosis. Show less
