This study aims to elucidate the pharmacological basis and antidepressant mechanisms of a combined extract from Eucommia ulmoides Oliv. And Gastrodia elata Bl. (Eucommia-Gastrodia extract), employing an integrated strategy that combines UHPLC-QTOF-MS analysis, network pharmacology, molecular docking, and in vivo validation. This research integrated computational approaches network pharmacology, molecular docking and in vivo experimental investigations. Initially, the active constituents of the EGE were identified through ultra-high-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry (UHPLC-QTOF-MS). Potential targets related to depression were predicted using the Traditional Chinese Medicine Systems Pharmacology Database (TCMSP) and SwissADME. Protein-protein interaction (PPI) networks were constructed via the STRING database, followed by the development of a comprehensive "drug-active ingredient-target-disease" network. Functional annotation through Gene Ontology (GO) and pathway enrichment analysis based on the Kyoto Encyclopedia of Genes and Genomes (KEGG) were conducted on the intersecting targets using the Database for Annotation, Visualization, and Integrated Discovery (DAVID). Molecular docking studies were erformed employing AutoDock software to validate the interactions. Finally, the antidepressant-like behavioral effects were evaluated in treated and non-treated corticosterone-induced mouse models using sucrose preference tests, forced swimming tests, open field tests, and tail suspension tests. The morphological impacts and molecular basis of disease on the hippocampal neurons were assessed using Hematoxylin and Eosin staining (HE) staining, Nissl staining, immunohistochemistry, and Western blot analysis to substantiate the identified through network pharmacology. Network pharmacology analysis revealed a complex interplay between identified active ingredients of Eucommia-Gastrodia extract and depression targets. From an initial pool of 131 active components, 34 identified as interacting with 233 shared depression related molecular targets. These targets were involved in 390 biological processes (BP), 60 cellular compounds (CC), 134 molecular functions (MF), and 148 KEGG-enriched signaling pathways. Molecular docking studies highlighted 20 principal compounds that bind to key targets such as AKT1, SRC, HIF-1, CREB, BDNF, and EPO. The Eucommia-Gastrodia extract alleviated depression like behaviors in a cortisol-induced mouse model, as indicated by increased sucrose preference and mobility time, etc. Additionally, the extract restored the levels of neurotransmitters 5-hydroxytryptamine (5-HT) and dopamine (DA), alleviated hippocampal neuronal damage, and increased the positive expression of EPO and BDNF in the hippocampus. Furthermore, treatment with the extract significantly upregulated the protein expression of HIF-1, EPO, EPOR, CREB, p-CREB, BDNF and p-TrkB, which were otherwise downregulated in cortisol-induced depressive mice. The results indicate that the Eucommia-Gastrodia extract containing bioactive compounds such as oxysophocarpine, aucubin, pinoresinol, leonurine, syringaresinol, formononetin, icaritin, casticin, and 6-gingerol mitigates cortisol-induced neurodegeneration and depressive-like behaviors. This effect is mediated through modulation of the of HIF-1α-EPO/cAMP-CREB-BDNF signaling pathways. Show less

DNA double-strand break repair has emerged as a vital pathway to repair DNA damage seriously related to the risk of colorectal cancer (CRC). To explore valid susceptible biomarkers of CRC via investigating the association of single nucleotide polymorphisms in DSBR genes with CRC risk, seven polymorphisms located in 3'-untranslated regions of DSBR genes including RAD51 rs11852786, RAD51B rs963917, BRCA1 rs12516 and rs8176318, BRCA2 rs15869, XRCC4 rs2035990 and XRCC5 rs2440 were detected and analyzed in a CRC case-control study (cases (202) and also controls (202)). The PolymiRTs and miRSNP database were used to predict the microRNAs that can bind to 3'UTR SNPs. Since long non-coding RNA as a miRNA "sponge" played the role of competing endogenous RNA, DAVID database was used to find the lncRNAs that can bind to the candidate miRNA seed sequences. BRCA1 rs12516 minor A allele was found to be linked with a higher risk of CRC than its major G allele (OR = 2.716, 95%CI: 1.394-5.292, P = 0.003). The stratified analyses demonstrated rs12516 AA genotype with a more elevated risk of CRC in male (OR = 3.089, 95% CI:1.315 ~ 7.255) or age > 50 population (OR = 3.318, 95%CI:1.571 ~ 7.006) than its GG genotype. BRCA1 rs12516 A allele created a novel miR-4704-5p binding target, and there was a negative correlation between miR-4704-5p and BRCA1 expression (r =-0.7199, P = 0.0440). Based on the theory of ceRNA network, it was predicted that lncRNA BDNF-AS can competitively bind to miR-4704-5p, whose expression was exhibited to be negatively correlated with BDNF-AS (r=-0.3481, P = 0.0375). On the contrary, BDNF-AS expression showed a positive correlation with BRCA1 mRNA level in colorectal tissue carrying rs12516 of A allele (adjacent tissue: r = 0.7269, P = 0.0411; cancer tissue: r = 0.7134, P = 0.0469). ROC curve showed both BDNF-AS (AUC = 0.651, P = 0.0277) and miR-4704-5p (AUC = 0.7215, P = 0.0012) can distinguish CRC tissues from their adjacent tissues. BRCA1 rs12516 is characterized as a potential biomarker associated with CRC risk, via a possible functional ceRNA network of BDNF-AS, miR-4704-5p and BRCA1. The interaction of a lower expression of BDNF-AS, a higher expression of miR-4704-5p and rs12516 A allele could together increase the risk of colorectal cancer. Show less

Microglia play dual roles in neuroinflammation, driving either detrimental M1 or protective M2 polarization, which critically impacts the outcomes of ischemic stroke. While fibroblast growth factor 20 (FGF20) is established as a neurotrophic factor with neuroprotective properties, its role in regulating microglial polarization remains unclear. This study investigated a novel function of FGF20 in alleviating post-stroke neuroinflammation and its underlying mechanisms. In a rat model of middle cerebral artery occlusion (MCAO), intracerebroventricular administration of FGF20 significantly reduced infarct volume and improved neurological function. RT-PCR analysis revealed that FGF20 bidirectionally regulated cytokine expression, suppressing M1-associated markers (CD86, IL-1β, IL-6, iNOS, TNF-α) while enhancing M2-associated markers (IL-10, Arg-1). Immunofluorescence staining demonstrated that FGF20 attenuated microglia activation in peri-infarct striatum and hippocampus. In vitro, FGF20 counteracted LPS-induced M1 polarization in primary microglia, downregulated the TLR4/NF-κB pathway, and upregulated TREM2 expression. Notably, while the selective FGFR1 inhibitor PD173074 abolished FGF20-induced TREM2 upregulation, it did not reverse the suppression of TLR4/NF-κB, indicating that these two effects are mediated through distinct regulatory mechanisms. These phenotypic shifts were further confirmed by a reduction in CD32/16 Show less

Alzheimer's disease (AD) is increasingly recognized as a disorder of innate immune dysregulation within the central nervous system. The triggering receptor expressed on myeloid cells 2 (TREM2), a microglial immunoreceptor, has emerged as a pivotal genetic risk factor for late-onset AD, underscoring the critical role of neuroimmune interactions in disease pathogenesis. This review synthesizes recent advances concerning TREM2's modulation of core microglial functions, including phagocytosis, inflammatory signaling, cellular metabolism, and survival, processes that are essential for responding to amyloid-β plaques and neuronal damage. We highlight the TREM2-APOE pathway as a central mechanism driving the disease-associated microglia (DAM) phenotype and examine how loss-of-function mutations such as Show less

Atherosclerosis is a chronic inflammatory condition marked by the deposition of lipids within the arterial wall and the infiltration of inflammatory cells, culminating in the development of atherosclerotic plaques. Ubiquitin-specific protease 18, USP18, a specific deubiquitinating enzyme, has been demonstrated to exert protective effects on the cardiovascular system. Pathological studies were performed utilizing human coronary arteries obtained from the Forensic Medical Examination Center of Guizhou Medical University, in conjunction with the aorta from experimental ApoE knockout mice. The ApoE knockout mice underwent intervention with adenovirus carrying USP18-RNAi and a control adenovirus containing hU6-MCS-CMV-EGFP, after which pathological analyses were conducted. In vitro, THP-1 cells, induced with phorbol ester, were subjected to treatment with si-USP18 or si-NC, followed by exposure to oxidized low-density lipoprotein. The expression levels of USP18 and proteins associated with the TAK1/NF-κB signaling pathway, as well as the interaction between USP18 and TAK1, were assessed using Western blotting, RT-PCR, and immunofluorescence techniques.The interaction between USP18 and TAK1 was confirmed using molecular docking techniques, co-immunoprecipitation assays, and immunofluorescence analysis. The purpose of this study is to explore the role of USP18 on atherosclerosis and the underlying mechanism. The expression of USP18 is elevated in early-stage human coronary atherosclerotic plaques but decreases in advanced lesions. Treatment of macrophages derived from THP-1 cells and bone marrow-derived macrophages (BMDMs) with lipopolysaccharide (LPS) results in reduced USP18 expression. In ApoE USP18 modulates TAK1 to suppress the activation of the NF-κB signaling pathway in macrophages, consequently exerting an anti-atherosclerotic effect and offering a potential therapeutic strategy for atherosclerosis treatment.

To elucidate the molecular mechanism by which ginsenoside Rg3 (G-Rg3) protects human bronchial epithelial (HBE) cells against lipopolysaccharide (LPS)-induced injury, focusing on its regulation of autophagic flux and the TLR4/NF-κB-mediated inflammatory pathway. HBE cells were treated with LPS (1-100 ng/mL) to induce autophagy dysregulation and inflammation. G-Rg3 (2-16 μM) was administered to evaluate its protective effects. Western blotting was used to detect autophagy-related proteins (ATG4B, ATG7, PIK3C3, LC3B, p62) and TLR4/NF-κB signaling molecules; ELISA quantified proinflammatory cytokines (TNF-α, IL-1β, IL-2, IL-6, IL-8); PI staining and flow cytometry analyzed cell death and apoptosis. LPS dose-dependently upregulated the expression of autophagy-related proteins (ATG4B, ATG7, PIK3C3, p62, LC3B-II), with accumulated p62 and LC3B-II indicating impaired clearance of autophagic substrates. Additionally, G-Rg3 inhibited LPS-induced TLR4/NF-κB activation, suppressed proinflammatory cytokine secretion, and attenuated HBE cell apoptosis/necrosis. G-Rg3 mitigates LPS-induced HBE cell injury by dual mechanisms: restoring impaired autophagic flux and inhibiting the TLR4/NF-κB inflammatory cascade. These findings identify G-Rg3 as a promising therapeutic agent targeting the crosstalk between autophagy and inflammation in respiratory diseases such as COPD and acute lung injury. Show less

Spinal cord injury (SCI) represents significant central nervous system trauma and has consistently been a focal point of research in the domain of neural regeneration and repair. Currently, there is no effective treatment available. Various modalities of magnetic stimulation have emerged for recovery from spinal cord injuries; however, the underlying mechanisms remain unclear, significantly hindering the application of magnetic stimulation technologies in treating such injuries. This study aims to elucidate these relevant mechanisms by establishing a simulated closed-loop magnetic stimulation system. In this study, we established a right hemisection model at T8 in mice and administered continuous simulated closed-loop magnetic stimulation targeting the left motor cortex and right L5 nerve root over six weeks. We subsequently utilized a spinal cord dorsal hemisection model to examine regeneration of the corticospinal tract (CST). Motor-evoked potential assessments and calcium imaging techniques were employed to explore neural circuit repair. Additionally, we integrated transcriptomics, proteomics, and metabolomics approaches to investigate related mechanisms. The findings indicate that simulated closed-loop magnetic stimulation effectively restores motor function in the hind limbs, promotes the regeneration of corticospinal tracts in mice with spinal cord injuries, and facilitates the reconstruction of sensorimotor circuits and functions within the spinal cord. Simulated closed-loop magnetic stimulation significantly enhances axonal regeneration of the CST following SCI. This effect may be mediated through the activation of the AMPK-CREB-BDNF signaling pathway, which promotes neurotrophic factor secretion and subsequently induces nerve axon regeneration. This study suggests that simulated closed-loop magnetic stimulation represents a promising therapeutic approach for the treatment for impaired gait following SCI. Show less

Our understanding of the intrinsic mechanisms that drive the regeneration of damaged axons after a spinal cord injury is still limited. Microtubules are core components of the eukaryotic cytoskeleton and are essential for axonal growth, in part because their stability is governed by post-translational modifications in mature neurons. Glucose-dependent insulinotropic polypeptide (GIP) and its receptor (GIPR) are expressed in multiple extra-pancreatic tissues, suggesting biological functions beyond classical endocrine signaling; however, their roles in neuronal cytoskeletal regulation are not well defined. Here, we investigated the effects of GIP in cultured cortical neurons. GIP enhanced microtubule stability and increased the number of axons crossing an inhibitory chondroitin sulfate proteoglycan (CSPG) border. Mechanistically, GIP promoted microtubule acetylation via α-tubulin N-acetyltransferase 1 (αTAT1), the major acetyltransferase for α-tubulin, by suppressing αTAT1 ubiquitination and thereby reducing its proteasomal degradation in inhibitory environments. Although the upstream mechanism remains to be determined, this study provides the first evidence that GIP/GIPR signaling modulates microtubule dynamics, highlighting a potential strategy to re-activate neuronal growth machinery after injury.

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.

Calcific aortic valve disease (CAVD), the most common human valve disease on a global scale, ranks and persists as an unaddressed clinical challenge. This is primarily attributed to the absence of efficacious pharmacological approaches. The Nuclear Receptor Subfamily 4 Group A Member 1 (NR4A1), intricately associated with the pathogenesis of multiple cardiovascular diseases, has emerged as a pivotal target for the diagnosis and treatment of numerous ailments. However, the specific molecular mechanisms and the functional significance of NR4A1 in the pathogenesis of CAVD are yet to be comprehensively elucidated. By performing in-depth analyses on human aortic valve tissues and carrying out functional investigations using primary valvular interstitial cells (VICs), we were able to demonstrate that NR4A1 significantly facilitated cellular proliferation and intensifies the osteogenic differentiation process of VICs. Evidently, this is reflected in the elevated expression of key osteogenic markers, namely runt-related transcription factor 2 (RUNX2) and alkaline phosphatase (ALP). Mechanistically, the pro-calcific effects were achieved via NR4A1-dependent modulation of the cell cycle regulatory protein Cyclin D2 (CCND2). Significantly, Show less

This article presents a case of a rare lymphoplasmacytic lymphoma (LPL) complicated by spherocytosis in a 74-year-old male. The patient reported progressive fatigue and anemia and had a medical history of type 2 diabetes, hypertension, and cerebral infarction. Laboratory tests indicated moderate anemia (hemoglobin 80 g/L) and a monoclonal increase in serum IgG. A bone marrow biopsy combined with immunohistochemistry confirmed the diagnosis of lymphoplasmacytic lymphoma (IgG-κ type, MYD88 L265P negative). A peripheral blood smear revealed an increase in spherocytes, a positive acidified glycerolysis test (AGLT50), abnormal erythrocyte osmotic fragility, and a negative direct antiglobulin test. Genetic screening for hereditary erythrocyte diseases showed no pathogenic variations. The patient's condition stabilized following targeted therapy with zanubrutinib and rituximab (ZR regimen). This case underscores the complexity of diagnosing dual hematological anomalies, highlights the importance of multidisciplinary collaboration, and seeks to explore the potential pathophysiological link between LPL and spherocytosis, offering a reference for diagnosis and treatment in similar clinical scenarios.

Flourishing is a key positive psychological construct that has been linked to favorable health-related outcomes in patients with inflammatory bowel disease in prior research. However, current research often overlooks the variations in flourishing levels within this population, as well as the mechanisms through which flourishing interacts with disease progression. This study aimed to identify latent categories of flourishing among patients with inflammatory bowel disease and to analyze the potential influencing factors. This study employed a cross-sectional, descriptive exploratory design involving 316 patients diagnosed with inflammatory bowel disease. Data collection was carried out using a general information questionnaire, the Flourishing Scale (FS), the IBD Self-Efficacy Scale (IBD-SES), the Resilience Scale for Inflammatory Bowel Disease (RS-IBD), and the Social Support Rating Scale (SSRS). Latent profile analysis (LPA) was utilized to identify potential subgroups exhibiting flourishing, while multiple logistic regression analysis was conducted to evaluate the influencing factors. The flourishing of individuals with inflammatory bowel disease was classified into three latent groups: the low flourishing-low support beneficiary group ( Patients with inflammatory bowel disease demonstrate three distinct latent categories of flourishing. Healthcare professionals should implement more accurate and targeted intervention measures based on the characteristics and influencing factors of different potential categories, in order to improve the flourishing levels of patients with inflammatory bowel disease.

Diabetic foot ulcers (DFU) are a severe complication of diabetes. Although dysregulated M2 macrophage polarization is recognized as a key driver of chronic inflammation in DFU, the molecular checkpoints that can be therapeutically targeted to restore M2 bias remain poorly defined. Here, we aimed to determine whether the RNA-binding protein TAF15 acts as a post-transcriptional stabilizer of the M2-promoting CEBPB/APOE/PTX3 axis, thereby accelerating DFU healing. First, we confirmed that APOE positively regulates PTX3, which supports M2 polarization and the proliferation and migration of HDF. CEBPB transcriptionally activated APOE and promoted M2 macrophage polarization. TAF15 stabilized CEBPB mRNA and affected HDF cell proliferation and migration by promoting M2 macrophage polarization. Additionally, TAF15 overexpression partially counteracted the disruption of M2 macrophage polarization caused by APOE silencing and facilitated DFU wound healing. Collectively, our findings establish TAF15-driven stabilization of CEBPB mRNA as a target point that sequentially activates APOE/PTX3 signaling to enforce M2 polarization and accelerate DFU closure. This study provides a preclinical rationale for the development of TAF15-targeted oligonucleotides or small-molecule strategies to reprogram wound macrophages and improve DFU outcomes in patients with diabetes.

To describe the network structure and heterogeneity of symptom burden in patients with acute coronary syndrome (ACS) after percutaneous coronary intervention (PCI), and to examine factors associated with different symptom burden profiles to inform risk-stratified management after PCI. A convenience sample of 261 patients with ACS who underwent PCI at a tertiary hospital in Chongqing between November 2024 and August 2025 was recruited. Data were collected using a demographic questionnaire, the Cardiac Symptom Survey, and the Seattle Angina Questionnaire. Network analysis was conducted to identify inter-symptom associations and the structural characteristics of the symptom network. Latent profile analysis (LPA) was performed to classify symptom burden patterns, and multinomial logistic regression analysis was used to explore factors associated with profile membership. Network analysis indicated that depression was the most central symptom (strength Symptom burden in patients with ACS after PCI demonstrates substantial individual heterogeneity. Depression occupies a central position within the symptom network, and BMI is associated with moderate and high symptom burden profiles. These findings suggest that integrating symptom network characteristics and BMI status into post-PCI assessment may facilitate risk-stratified management and targeted psychological and weight-related interventions to improve recovery outcomes.

As sports socializing is becoming a dominant lifestyle that integrates physical health with social interaction in China, understanding the underlying drivers of participation is crucial. However, traditional research predominantly relies on a “variable-centered” paradigm, which assumes population homogeneity and focuses on linear relationships between single motives and behaviors. This approach often fails to capture the complexity of how multiple motivations are configured within individuals (heterogeneity), and how these internal configurations are associated with external behavioral choices. To address this gap, this study employed a novel hybrid methodological framework combining Latent Profile Analysis (LPA) and Random Forest (RF) modeling. Based on data from 1,104 adults, LPA was first used to identify distinct motivational subgroups. Subsequently, RF algorithms, utilizing feature importance ranking and “One-vs-Rest” strategies, were applied to identify the associative patterns between these motivational profiles and key behavioral indicators, including sports types, media usage, and economic investment. The analysis identified four distinct motivational profiles: (1) Psychologically Introverted (3.6%), prioritizing internal psychological rewards over social status; (2) Physiologically Oriented (44.1%), the largest group, driven primarily by physical health needs; (3) Balanced (39.0%), exhibiting moderate levels across all motivational dimensions; and (4) High-Motivation/Comprehensively Oriented (13.3%), showing high intensity in both internal and external rewards. The RF model achieved a training accuracy of 99.9% and identified that Sports Type (specifically large-ball games), Media Channels (particularly Douyin/Rednote), and Annual Spending were the top three salient behavioral markers distinguishing these profiles. Notably, the High-Motivation group was characterized by heavy reliance on visual social media for social display. Participation in sports socializing among Chinese residents is not characterized by a singular, homogeneous motivation but features a clear internal stratification structure. The specific pattern of motivational combinations (i.e., the type) systematically maps onto external behavioral choices, where the sociocultural attributes of the sport and the media characteristics of digital social platforms constitute the key predictive markers of behavioral differentiation. The establishment of this “Motivation Type—Behavioral Signal” integrated framework promotes a theoretical shift in the sports socializing research paradigm from “homogeneity” to “heterogeneity” and deepens the understanding of the complex manifestations of Self-Determination Theory and Social Capital Theory in a sports context. It also provides precise user profiles and behavioral insights for sports social platforms, commercial clubs, and public sports service departments. Exploring service customization and policy adjustments based on different motivation-behavior patterns could potentially enhance user engagement and satisfaction, suggesting a possible direction for the development of the sports socializing industry.

This study aimed to assess the childbirth readiness of women in their third trimester of pregnancy and to identify distinct readiness profiles using latent profile analysis (LPA). Additionally, it explored the factors influencing childbirth readiness in order to guide targeted interventions for improved maternal and neonatal outcomes. A cross-sectional study was conducted among women in their third trimester of pregnancy between May and November 2024. Eligible participants completed a general information questionnaire, the Childbirth Readiness Scale (CRS), the Childbirth Attitude Questionnaire (CAQ), and the Perceived Social Support Scale (PSSS). LPA identified three groups with distinct childbirth readiness levels: "Low Readiness - Childbirth Knowledge Deficit" (37.9%), "Moderate Readiness - Good Lifestyle Habits" (47.9%), and "High Readiness - Rich Health Knowledge" (14.2%). In addition, gestational age, previous childbirth history, adverse pregnancy outcomes, childbirth attitudes, and social support had different influences on women in different latent profiles of childbirth readiness. There was significant heterogeneity in childbirth readiness among women in their third trimester. Women with lower readiness-especially in childbirth knowledge-would greatly benefit from targeted educational programs, whereas those with moderate readiness levels would find enhanced emotional and psychological support most advantageous. These findings support the implementation of profile-based, personalized prenatal care strategies to improve childbirth preparedness and optimize maternal and neonatal outcomes. Show less

Atherosclerosis is a chronic inflammatory disease marked by lipid accumulation and immune cell infiltration in arterial walls. Macrophages contribute by internalizing oxidized low-density lipoprotein, forming foam cells, and driving inflammation. The ubiquitin-proteasome system regulates immune and inflammatory responses in atherosclerosis. This study investigated the protective role of TRIM31 (tripartite motif-containing 31), an E3 ubiquitin ligase, in macrophage lipid metabolism and inflammation through selective regulation of LOX-1 (lectin-like oxidized low-density lipoprotein receptor-1). Transcriptomic profiling, macrophage-specific TRIM31 was selectively upregulated in macrophages under oxidized low-density lipoprotein stimulation and in atherosclerosis plaques. Trim31 deficiency exacerbated plaque burden, foam cell formation, and inflammatory signaling (n=8 per group). Single-cell analysis revealed enrichment of lipid transport and inflammatory pathways in Trim31-deficient plaques. LOX-1 was identified as a key TRIM31 substrate. TRIM31 promoted K48-linked ubiquitination of LOX-1 at lysine 12, facilitating its degradation. The atheroprotective effects of Trim31 were abolished in TRIM31, an inducible, macrophage-enriched protective factor in atherosclerosis, restricts foam cell formation and inflammation by targeting LOX-1 for proteasomal degradation. These findings position TRIM31 as a promising therapeutic target for macrophage-driven atherogenesis. Show less

Endoplasmic reticulum (ER) stress plays a significant role in chronic pain, but its potential involvement in chronic itch remains largely unexplored and poorly understood. In the current study, we investigated whether ER stress signaling in keratinocytes contributes to the pathogenesis of chronic itch. Our behavioral tests showed that the ER stress inhibitor 4-PBA attenuated itch-related behaviors in both acute and chronic itching mouse models, and reduced compound 48/80 and serotonin-induced activity of dorsal root ganglion (DRG) neurons. qPCR and western blotting revealed that the ER stress-related proteins and Lipocalin-2 (LCN2) were significantly elevated in the affected skin under chronic itch conditions and in cultured keratinocyte HaCaT cells and mice skin keratinocytes. The ELISA test showed that the level of LCN2 increased significantly in plasma but not in DRG tissue, from both acetone-ether-water (AEW) induced dry skin and imiquimod (IMQ) induced psoriasis model mice. Current clamp recording demonstrated that LCN2 induced hyperexcitability in dorsal root ganglia neurons, which could be abolished by HS024, the inhibitor of melanocortin receptor 4 (MC4R). In addition, pharmacological inhibition of transient receptor potential vanilloid 1 (TRPV1) or TRPV1 knockout blocked LCN2-induced hyperexcitability in DRG neurons. In conclusion, this study demonstrated that keratinocyte ER stress is involved in chronic itch genesis by releasing LCN2, which sensitized primary sensory neurons via TRPV1. These findings suggested that inhibition of ER stress in keratinocytes could be a promising therapeutic strategy for treating chronic itch. Show less

This narrative review systematically synthesizes recent clinical and pre-clinical evidence to elucidate the latest neurobiological mechanisms underlying acupuncture for post-stroke insomnia combined with cognitive impairment (PS-ICI). PS-ICI is characterized pathologically by a hippocampal-prefrontal circuitry-mediate "sleep-cognition vicious cycle" and clinically by concurrent cognitive decline and sleep-architecture disruption, both of which markedly impede post-stroke neurological recovery. Grounded in the Traditional Chinese Medicine (TCM) principle of "regulating Shen and re-animating the brain, "acupuncture exerts bidirectional modulation on cognition and sleep, significantly improving core functional outcomes and activities of daily living. Up-to-date studies confirm that synergistic, multi-dimensional effects are achieved through regulation of the BDNF-TrkB-PI3K/Akt signaling axis, preservation of neurovascular unit integrity, restoration of gut-brain axis homeostasis, normalization of circadian immune rhythms, and reshaping of default-mode network (DMN) plasticity. Given the high heterogeneity of included studies, a qualitative integrative approach was employed. Current evidence is nevertheless limited by small sample sizes, short follow-up durations, and substantial heterogeneity in acupuncture parameters (frequency and point selection); future work must therefore focus on dissecting inter-pathway interactions, standardizing therapeutic protocols, and integrating multi-omic technologies to propel acupuncture toward precision, evidence-based management of PS-ICI.

Atherosclerotic plaque rupture, driven by a vicious pathological cycle between endothelial-to-mesenchymal transition (EndMT) and chronic inflammation, represents a major therapeutic challenge in cardiovascular disease. Current clinical strategies, including statins and antiplatelet agents, fail to disrupt the EndMT-inflammation axis, while conventional TGF-β pathway inhibitors-critical for EndMT regulation-exhibit narrow therapeutic windows and systemic toxicity owing to the pleiotropic nature of TGF-β signaling. Here, we reported VRBPC, a VCAM-1-targeting, reactive oxygen species (ROS)-responsive baicalin-peptide conjugate that undergoes in situ self-assembly within atherosclerotic plaques to form a "molecular latch" that breaks the EndMT-inflammation loop. Upon VCAM-1-mediated endocytosis into activated endothelial cells, VRBPC responds to elevated ROS levels in the plaque microenvironment, triggering localized self-assembly that enhances baicalin retention and promotes its competitive binding to HSP90-a critical chaperone for TGF-β receptor stabilization. This mechanism inhibits Smad2/3 phosphorylation, reverses EndMT, and simultaneously suppresses inflammatory responses in macrophages.

To investigate the dose-response relationship between e-health literacy and light physical activity (LPA) in older adults is to provide evidence for targeted interventions that enhance e-health literacy and promote LPA, thereby advancing healthy aging. This study used a convenience sampling method to select two residential neighborhoods. Subsequently, a random cluster sampling approach was employed, resulting in a total final sample of 105 community-dwelling older adults (aged 60 and above) from these neighborhoods. A three-axis accelerometer (ActiGraph wGT3X-BT) recorded the older adults' LPA, and the Electronic Health Literacy Scale assessed their e-health literacy. Multiple linear regression was used to explore the dose-response relationship between LPA and e-health literacy and sub-dimension scores. Multiple linear regression revealed that both the overall e-health literacy score and its components were positively associated with daily LPA (Tables 2 and 3). However, the empirical impact varied substantially across components. For each 1-point increase, LPA increased by 2.8 min for the overall score, 11 min for judgment ability, and 19.4 min for decision-making ability, whereas the effect of application ability was statistically significant but minimal. Notably, the effect sizes of all e-health literacy components were substantially smaller than that of educational attainment (β = 0.638-0.947), which was the strongest predictor in all models. This study provides empirical evidence that higher e-health literacy and its specific sub-dimensions are positively associated with light physical activity (LPA) among community-dwelling older adults, with educational attainment emerging as a key independent predictor. These findings suggest that public health interventions aimed at promoting LPA could be enhanced by incorporating strategies to improve e-health literacy, particularly targeting older adults with lower educational backgrounds. The development of tailored, theory-informed programs based on these insights holds promise for fostering healthy aging at the community level. Show less

Obesity has become a global epidemic and a major contributor to the development of Type 2 diabetes (T2D) through the promotion of insulin resistance. Emerging evidence has shown that GPX4 expression is reduced in macrophages under hyperglycemic conditions; however, the involvement of macrophage-specific GPX4 in obesity-associated insulin resistance remains unclear. We generated macrophage-specific Gpx4 knockout (Gpx4 Show less

While mindfulness has demonstrated efficacy in enhancing executive function in non-athletes through improved present-moment awareness and acceptance of current experiences, particularly regarding attention regulation and cognitive control, its neurocognitive mechanisms and the effects and underlying mechanisms of mindfulness-based intervention (MBI) on different executive functioning skills in athletic populations remain poorly understood. The purpose of this randomized controlled trial tackles a novel and important topic by investigating the beneficial effects of 12-week MBI on executive functioning skills in baseball players-a population that faces unique cognitive and physical demands, and the associated neurophysiological and biochemical regulation mechanisms. Thirty-four baseball players were randomly divided into the MBI group (11M/6F) and the control group (11M/6F). Executive functioning skills (N-back task for working memory, Stroop task for inhibitory control, and Switching task for cognitive flexibility) were tested before and after the intervention. Functional near-infrared spectroscopy (fNIRS) was used to record quantified hemodynamic responses in the prefrontal cortex through oxygenated hemoglobin concentration (Oxy-Hb) monitoring during the performance of executive function tasks. Biomarkers of cognitive function, including BDNF, IL-6, TNF-α, and Cortisol, were measured using enzyme-linked immunosorbent assays (ELISA). MBI partially improved all three executive function skills, with increased Oxy-Hb level in L-FPA during the task of working memory, increased Oxy-Hb level in R-VLPFC during the task of inhibitory control, and decreased Oxy-Hb level in R-FPA, M-FPA, and L-DLPFC during the task of cognitive flexibility. Furthermore, MBI increased circulating BDNF level and decreased IL-6 and Cortisol levels. In addition, our correlation analyses showed that improvement in executive function (improved behavioral performances and changes in Oxy-Hb levels) were associated with changes in Cortisol and inflammatory cytokines (TNF-α and IL-6). A 12-week MBI partially improved three components of executive function in baseball players. This enhancement may be attributed to the MBI-induced reductions in Cortisol and inflammatory cytokines (such as TNF-α and IL-6), which altered blood oxygen contents in specific brain regions, thereby promoting executive function.

As a progressive neurological degenerative disorder, Alzheimer's disease (AD) remains a significant concern, with the lack of effective cures burdening healthcare resources and posing ongoing obstacles for scientific research in neuroscience. Tianwang Buxin Pills (TWBXP) is a traditional Chinese medicinal formula long employed for treating amnesia and cognitive decline, and has shown promising potential in AD treatment. Nevertheless, the detailed mechanisms responsible for these effects warrant further investigation. This study seeks to systematically evaluate the impact of TWBXP on cognition, neuronal damage, and synaptic plasticity in AD mice, while clarifying its underlying therapeutic mechanisms. HPLC-UV was employed to ensure the quality of TWBXP. APP/PS1 mice were administered TWBXP (0.43, 0.85, 1.70 g/kg) for 8 weeks, and cognitive performance was assessed using behavioral tests. AD-related pathology was evaluated by Immunohistochemistry (IHC), Western blotting, ELISA, Transmission electron microscopy (TEM), and Immunofluorescence (IF). The integration of Network Pharmacology and Proteomics was conducted for the exploration of potential mechanisms. TWBXP markedly improved cognitive performance and reduced cerebral Aβ burden. It promoted microglial polarization toward an M2 phenotype, dampened neuroinflammation, and enhanced microglia-associated Aβ clearance. TWBXP also exerted marked neuroprotective and synaptic protective effects by increasing NeuN, MAP2, and MBP levels, restoring synaptic proteins (PSD95, SYP) and neurotrophic factors (BDNF, NGF), reducing neuronal loss and functional impairment, and improving synaptic plasticity. Such effects might be associated with the enhanced activity of the cAMP/PKA/NR2B/CaMKⅡ signaling axis. TWBXP significantly ameliorated cognitive impairment and AD-related pathological changes in APP/PS1 mice, accompanied by improvements in neuronal injury and synaptic plasticity. Its therapeutic effects may be associated with the regulation of microglial function and the cAMP/PKA/NR2B/CaMKII signaling axis. Show less

The development of vascular calcification (VC) in diabetes is closely related to the endothelial-to-mesenchymal transition (EndMT). We found that microRNA-32-5p (miR-32) was elevated in the plasma of calcification patients. However, it is unclear whether miR-32 mediates the function of bone marrow mesenchymal stem cell-derived extracellular vesicles (BMSC-EVs) in type 2 diabetes (T2D) VC. BMSC-EVs were characterized by TEM, NTA, Western blotting, and confocal microscopy. Alizarin Red and ALP staining assessed the severity of VC. qRT-PCR and Western blotting evaluated the expression of BMP2, RUNX2, GPX4, SLC7A11, VE-cadherin, and N-cadherin, while immunofluorescence was used for detecting VE-cadherin and N-cadherin. In vivo validation was performed using miR-32 We demonstrated that BMSC-EVs attenuate VC in endothelial cells (ECs) and inhibit EndMT. In vivo, histological analysis showed that treatment with BMSC-EVs significantly reduced the severity of VC associated with T2D. Notably, knockout of miR-32 further enhanced the inhibitory effect of BMSC-EVs on VC. Mechanistically, transcriptomic and functional analyses suggest that the protective effect of BMSC-EVs on VC is associated with regulation of the MAPK/FoxO signaling pathway, potentially mediated by modulation of ferroptosis. These findings demonstrate that BMSC-EVs attenuate T2D-associated VC, partially through miR-32-mediated suppression of EC ferroptosis. Show less
