The pathological environment of atherosclerosis (AS) is characterized by hyperlipidemia and chronic inflammation, which cause increased heterogeneity among vascular smooth muscle cells (VSMCs). Owing to its lipid-regulating and anti-inflammatory effects, paeoniflorin (Pae) inhibits VSMC phenotypic transformation, making it a promising candidate for AS treatment. Mouse aortic VSMCs were treated with oxidized low-density lipoprotein (ox-LDL) and Pae, and the effects on cell phenotype were examined. An AS model was established by feeding ApoE Pae reversed weight gain and elevated TG levels in the AS model. Oil Red O staining showed that Pae inhibited VSMC-derived foam cell formation in vitro and reduced aortic sinus plaque area, aortic wall lipid deposition, and hepatic steatosis in the AS model. Immunofluorescence staining of the aortic sinus revealed that Pae mitigated α-SMA overexpression and reversed ATP-binding cassette transporter A1 (ABCA1) downregulation. Western blotting analysis revealed that Pae inhibited ERK1/2 and p65 phosphorylation, curbed MMP2 overexpression, and restored downregulated ABCA1 expression. Cell Counting Kit-8, 5-ethynyl-2'-deoxyuridine staining, and wound healing assays demonstrated that Pae inhibited ox-LDL-induced VSMC proliferation and migration. Additionally, Pae significantly inhibited the expression of the inflammatory factors IL-6 and MCP-1 both in vivo and in vitro. Pae may treat AS by inhibiting VSMC phenotypic transformation. Show less

Nasopharyngeal carcinoma (NPC) is a complicated pathological cancer, which has a close association with pyroptosis and abnormal alternative splicing (AS). However, the molecular changes and functions of AS-mediated pyroptosis in cisplatin-resistant NPC cells remain poorly understood. The expression patterns of different splicing isomers of dual-specificity phosphatase 6 (DUSP6) were evaluated by semi-quantitative PCR. The effects of DUSP6 knockdown on cisplatin sensitivity and pyroptosis in NPC were examined by CCK-8 assay, immunofluorescence and ELISA. The occurrence mechanism of DUSP6 AS was explored by RNA pull down, mass spectrometry and MeRIP-PCR. DUSP6 underwent AS, among which the intron retention isoform DUSp6-IR1 increased in expression dependent on the dose and time of cisplatin. Knockdown of DUSP6-IR1 significantly suppressed viability and cisplatin resistance and promoted apoptosis of C666-1 cells upon cisplatin treatment. In vivo, sh-DUSP6-IR1 reduced the weight and volume of tumors. While DUSP6-IR1 knockdown in C666-1 cells enhanced pyroptosis (evidenced by elevated LDH release, Gasdermin D (GSDMD)/NOD-like receptor thermal protein domain associated protein 3 (NLRP3) expression, and IL-18/IL-1β levels, along with reduced cell viability), these effects were reversed by a pyroptosis inhibitor. The m6A reader protein insulin-like growth factor 2 mRNA-binding protein 3 (IGF2BP3) enhanced the splicing generation of the DUSP6-IR1 isoform through its KH3-4 domains, thereby suppressing pyroptosis in NPC cells and ultimately conferring cisplatin resistance. These findings revealed a promising novel direction to investigate cisplatin resistance and suggested potential therapeutic target for overcoming chemotherapy resistance in NPC.

The pathological mechanism of Alzheimer's disease (AD) is complex. The binding of Aβ to α7 nicotinic acetylcholine receptor (α7nAChR) contributes to neuronal damage. Sinomenine (SIN) is an alkaloid extracted from the traditional Chinese medicine Qingfengteng (Sinomenium acutum). The anti-inflammatory, antioxidant, and immunomodulatory effects of SIN were confirmed to be closely associated with the α7nAChR. This study aimed to investigate whether α7nAChR serves as a pharmacological target of SIN against AD, and to evaluate the neuroprotective effects of SIN both in vivo and in vitro, focusing on the α7nAChR/Nrf2/Keap1 signaling pathway. In this study, the effects of SIN in both APP/PS1 transgenic mice and SH-SY5Y cells subjected to Aβ1-42-induced injury were assessed. The selective antagonist α-bungarotoxin (α-BTX), the agonist nicotine (Nic) of α7nAChR, and α7nAChR siRNA were employed. The cognitive function, Aβ deposition, synaptic plasticity markers, the tau protein phosphorylation, mitochondrial membrane potential, oxidative stress and the α7nAChR/Nrf2/Keap1 signaling pathway were analyzed in vivo and/or in vitro. SIN significantly enhanced learning and memory abilities in APP/PS1 mice, reduced Aβ plaque deposition and synaptic dysfunction, and inhibited hyperphosphorylation of tau protein and oxidative stress in the brain. In Aβ1-42-induced neuronal injury model, SIN alleviated apoptosis, increased BDNF and ACh levels, inhibited mitochondrial damage, stabilized calcium homeostasis, and suppressed oxidative stress. Meanwhile, SIN disrupted Nrf2-Keap1 binding to promote the Nrf2/HO-1 signaling pathway. Nevertheless, SIN effects above were inhibited by α-BTX. The knockdown of α7nAChR in vitro significantly promoted Nrf2/HO-1 pathway and BDNF expression. SIN exerts neuroprotective effect in APP/PS1 transgenic mice and Aβ1-42-induced neuronal injury by inhibiting oxidative stress via α7nAChR/Nrf2/Keap1 pathway. This study provides evidence for α7nAChR as a new target and the clinical application potential of SIN in AD treatment. Show less

Hepatitis B virus (HBV) infection can cause liver damage through oxidative stress (OS) and immune-inflammatory responses. This study aims to explore the clinical significance of fibroblast growth factor 21 (FGF21) in the development and progression of chronic hepatitis B (CHB). A total of 336 participants were recruited, including 320 CHB patients and 16 healthy controls. The expression of FGF21, immune cytokines, and OS-related molecules in peripheral blood mononuclear cells (PBMCs) was detected using real-time quantitative polymerase chain reaction. The methylation level of the FGF21 gene promoter in PBMCs was detected using TaqMan probe-based quantitative methylation-specific PCR. The expression level of FGF21 in the peripheral blood of CHB patients was higher than that of HC, but the methylation level of the FGF21 promoter was lower than that of HC, especially in patients during the immune activation phase. The mRNA expression levels of CXCR3 and CCL5 in PBMCs of CHB patients during the immune activation and reactivation phases were higher than those in other clinical stages. Single-cell analysis revealed that CXCR3 and CCL5 expression in the immune tolerance and immune activation phases with high HBsAg expression was closely related to T lymphocytes (T cells) and natural killer cells (NK cells) and was highly expressed in CD4 and CD8 T cells and NK cells. In addition, the mRNA expression levels of Nrf2 and GPX4 in the reactivation phase were higher than those in other clinical stages. The mRNA expression level and methylation level of FGF21 in PBMCs of CHB patients were correlated with the viral load, immune inflammation, and OS levels during the antiviral treatment course of CHB. The methylation level of the FGF21 promoter has the potential to become a non-invasive biomarker for monitoring the progress of antiviral treatment in CHB.IMPORTANCEThis study conducted an in-depth exploration of the application of methylation detection technology, analyzing its value and driving mechanism in the oxidative stress and immune-inflammatory balance during the course of chronic hepatitis B. The study analyzed the methylation patterns of the FGF21 promoter and the expression levels of its receptor FGFR1, as well as the expression levels of chemokines CXCR3, CCL5, and oxidative stress factors GPX4 and Nrf2 in the immune tolerance period, immune clearance period, immune control period, and reactivation period of chronic hepatitis B. It clarified the association between these molecules and the FGF21/FGFR1 axis and revealed the synergistic or antagonistic mechanisms of these molecules in the oxidative stress and inflammatory vicious cycle. At the same time, this study also explored the value of FGF21 promoter methylation in disease diagnosis and prognosis, providing a theoretical basis for evaluating the antiviral treatment effect and disease progression of chronic hepatitis B.

Schizophrenia (SCZ) is a complex psychiatric disorder, and its pathogenic mechanisms are not yet fully understood. The identification of reliable blood biomarkers and molecular subtypes for early diagnosis and effective therapy remains a significant challenge. To address this issue, we utilized a combination of bioinformatics and machine learning (ML) to identify potential biomarkers for SCZ. Our approach involved the integration of 12 different ML algorithms to develop a diagnostic signature based on data from several datasets, including GSE18312, GSE27383, GSE38485, GSE54913, and GSE165604. A nomogram was constructed using these datasets for potential clinical applications. In addition, clustering analysis was performed on SCZ patients using consensus clustering and non-negative matrix factorization (NMF) algorithms. We further evaluated subtype differences in biological functions and immune cells through various methods, such as gene set enrichment analysis (GSEA), gene set variation analysis (GSVA), Proteomaps, and IOBR analyses. Our results identified a diagnostic signature composed of 16 genes (APBB2, CLCN1, SYDE1, PAX5, SNAI1, DAZL, UNC93B1, PLAGL2, HS3ST1, ITPKB, PILRA, BTLA, SWAP70, AZI2, ADM, and AVPR2), which demonstrated robust performance in diagnosing SCZ across eight different datasets. A nomogram based on these genes was created, providing clinical benefits for SCZ patients. Among the identified genes, AZI2 was found to be the most critical, influencing inflammation and immunity. We also identified potential chemical compounds that could target these 16 genes. Unsupervised clustering and NMF algorithms revealed two distinct subtypes of SCZ, each associated with unique immune cell profiles, biological functions, and protein expression levels. In conclusion, this study not only developed a diagnostic signature and a novel nomogram for SCZ but also provided new insights into the subtypes of SCZ. These findings may pave the way for personalized diagnosis and treatment strategies for SCZ patients. Show less

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.

Major depressive disorder is a severe mental health condition characterized by persistent depressed mood and loss of interest. Current first-line pharmacotherapies often exhibit limited therapeutic performance and adverse side effects. Transcutaneous auricular vagus nerve stimulation (taVNS) is a promising, safe, and noninvasive alternative intervention with demonstrated neuromodulatory efficacy. Nevertheless, its mechanisms remain unclear. This study investigated whether the antidepressant properties of taVNS are associated with the microbiota-gut-brain axis, focusing on the potential crosstalk between differentially expressed hippocampal proteins and the gut microbiota. A chronic unpredictable mild stress (CUMS) rat model of depression was established, and taVNS was administered for 14 days. Hippocampal proteomic profiling was performed using data-independent acquisition. Fecal metagenomic sequencing was conducted to characterize alterations in gut microbial communities. Key signaling pathways were validated using Western blot, qRT-PCR, HE staining, and transmission electron microscopy, all of which were employed to systematically assess behavioral, proteomic, microbial, and molecular changes. Proteomics and molecular analyses revealed that taVNS upregulated hippocampal expression of glutamate ionotropic receptor N-methyl-D-aspartate type subunit 1 (GluN1) and brain-derived neurotrophic factor (BDNF), while simultaneously restoring mitogen-activated protein kinase (MAPK) signaling activity. Metagenomic profiling demonstrated that taVNS increased the abundance of TaVNS significantly alleviated depression-like behaviors in CUMS-exposed rats. The underlying mechanism may involve the restoration of synaptic function of glutamatergic neurons by regulating the GluN1/MAPK/BDNF signaling pathway. In addition, taVNS reshaped the gut microbiota, markedly increasing the abundance of Show less

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

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

Alzheimer's disease (AD) is a progressive neurodegenerative disorder characterized by cognitive dysfunction that is closely associated with cholinergic system damage. Estrogen deficiency is a well-established risk factor for AD in women. Osthole (OST), a phytoestrogen with mild, bidirectional regulatory properties, has been proposed as a potential estrogen replacement. This study aimed to investigate the mechanisms by which OST ameliorates cognitive impairment. Cognitive deficits were induced in female Sprague-Dawley rats by bilateral ovariectomy (OVX), and OST was subsequently administered by oral gavage. Behavioral tests revealed that OST significantly improved learning and memory and reduced anxiety-like and depression-like behaviors in OVX rats. H&E staining and Nissl staining demonstrated that OST reversed neuronal damage in the hippocampus and cortex. Western blotting, ELISA, and immunofluorescence staining indicated that OST treatment restored the estrogen-cholinergic-NGF axis: E Show less

The role of efferocytosis in chronic rhinosinusitis (CRS), particularly CRS with nasal polyps (CRSwNP), remains poorly understood. We comprehensively characterized efferocytosis in CRS and determined its association with inflammatory endotypes and clinical outcomes in CRSwNP. Efferocytosis-related marker expression between nasal polyps and healthy nasal mucosa was detected by quantitative real-time PCR and immunohistochemistry. Public single-cell RNA sequencing profiles of CRS were reanalyzed to dissect efferocytosis at single-cell resolution. Associations between efferocytosis and tissue inflammation were evaluated by Spearman correlation. Regression models and receiver operating characteristic analyses assessed the predictive capability of efferocytosis for CRSwNP recurrence. Compared with controls, CRSwNP exhibited widespread efferocytosis deficiency, including "find me" signals (CX3CR1, S1PRs, P2RY2, GPR132), "eat me" signals (ITGAV, MerTK, Tim1, ADGRB1), "don't eat me" signal CD300a, postengulfment signals (ABCA1, NR1H3/2, PPARδ/γ), and bridging molecule MFGE8. Macrophages, the principal efferocytic cells, shifted from homeostatic C3 Insufficient phagocytosis and increased antiphagocytosis activity are hallmarks of efferocytosis deficiency in CRS and are associated with the severity of inflammation and the clinical outcome of CRSwNP.

To investigate the role of PINK1/Parkin-mediated mitophagy in regulating synaptic remodeling of neuronal cells in depression-like behaviors induced by nonylphenol (NP). In vitro experiments: HT-22 neuronal cells were exposed to NP, and mitophagy and Parkin expression were inhibited using specific inhibitors. The cells were categorized into the following groups: (1) control (C) and low-dose NP group (L: 2.5 µM), medium-dose NP group (M: 50 µM), and high-dose NP groups (H: 100 µM); (2) control (C), NP (100 µM), Mdivi-1 (5 µM), and Mdivi-1 + NP (5 µM Mdivi-1 +100 µM NP) groups; (3) control (C), NP (100 µM), AC220 (2 nM), and AC220 + NP (2 nM AC220 +100 µM NP) groups. In vivo experiments: a total of 48 mice, including 24 C57BL/6 wild-type mice and 24 PKRK2 gene-knockout mice, were randomly assigned to the following four groups: control (C), NP (100 mg/kg/day), PKRK2-knockout (KO), and PKRK2-knockout + NP (100 mg/kg/day, KH) groups, with 12 mice in each group. In vitro: With increasing NP concentration, the ATP content reduced and the expressions of synaptic remodeling-related proteins (i.e., PSD-95, BDNF, SYN) decreased. In contrast, the expressions of mitophagy-related proteins and those involved in the PINK1/Parkin-signaling pathway (such as p62, Beclin1, PINK1, Parkin) increased (P < 0.05). Inhibition of mitophagy with Mdivi-1 alleviated the NP-induced changes in synaptic, mitophagy-related, and PINK1/Parkin pathway-related proteins. Similarly, the inhibition of Parkin with AC220 mitigated NP-induced effects on synaptic, mitophagy-related, and PINK1/Parkin-signaling pathway-related proteins and mRNA expression. In vivo: PKRK2 gene-knockout mice exhibited improved NP-induced depression-like behaviors and decreased NP-induced synaptic morphology and mitochondrial ultrastructure changes. Moreover, the gene knockout alleviated the downregulation of synaptic remodeling-related proteins and inhibited the PINK1/Parkin-signaling pathway-mediated mitophagy activated by NP. Mitophagy inhibition or PKRK2 knockout can alleviate NP-induced downregulation of synaptic remodeling-related proteins, protect synaptic morphology and ultrastructure, and improve NP-induced depression-like behaviors.

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

Long-term antigen-specific data in PMN among Chinese populations remain limited. This study evaluated six target antigens and their clinical significance during extended follow-up. We retrospectively analyzed 132 treatment-naïve PMN patients diagnosed by biopsy (2010-2018) and followed for a median of 62.9 months. Renal tissue expression of PLA2R, THSD7A, NELL-1, PCDH7, EXT1, and EXT2 was assessed by immunohistochemistry, and serum anti-PLA2R antibodies were measured by ELISA. Associations between antigen profiles and 5-year outcomes (remission, renal survival, malignancy) were evaluated. PLA2R was the predominant antigen (84.1%), followed by THSD7A (5.3%) and NELL-1 (0.76%); no PCDH7, EXT1, or EXT2 positivity was detected. PLA2R-negative patients were more often female (71.4% vs. 36.0%, This >5-year Chinese PMN cohort provides the first comprehensive analysis of six target antigens. PLA2R remains predominant, while PLA2R-negative patients distinct immunopathologic features yet favorable long-term outcomes. A population-specific anti-PLA2R cutoff showed good diagnostic performance for predicting tissue antigen deposition. Rare antigens were infrequent and their malignancy associations require cautious interpretation. These findings provide long-term antigen-specific data supporting antigen-guided, population-adapted precision management of PMN. Show less

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.

This study employed a person-centered approach to identify latent profiles of academic burnout among Chinese university students and to examine the associations between academic burnout profiles and smartphone addiction, sleep quality, and mindfulness. A sample of 2,948 Chinese university students was recruited to complete measures of academic burnout, smartphone addiction, sleep quality, and mindfulness. Latent profile analysis (LPA) was used to identify distinct burnout profiles, and multinomial logistic regression was used to analyze factors associated with profile membership. Three distinct profiles of academic burnout were identified: a Low Burnout profile (18.15%), a Medium Burnout profile (50.88%), and a High Burnout profile (30.97%). The profiles differed significantly on all correlates, with the high burnout group exhibiting the most severe smartphone addiction, the poorest sleep quality, and the lowest mindfulness. Regression analysis revealed that higher smartphone addiction and poorer sleep quality were significantly associated with membership in the Medium and High Burnout profiles relative to the Low Burnout profile, whereas higher mindfulness was significantly associated with lower likelihood of belonging to higher burnout profiles. Academic burnout among Chinese university students is a heterogeneous experience, with a majority falling into an at-risk or intermediate state. Smartphone addiction, poor sleep, and low mindfulness are associated with higher burnout risk. These findings highlight the need for universities to develop targeted, profile-based interventions to provide precise and effective mental health support. However, due to the cross-sectional design, causal relationships cannot be inferred. Show less

Dibutyl phthalate (DBP) is a widely distributed endocrine-disrupting chemical with potential carcinogenic properties, yet its role in head and neck squamous cell carcinoma (HNSC) remains unclear. Here, we applied an integrative framework combining network toxicology, Mendelian randomization (MR), multi-omics analyses, molecular docking, molecular dynamics simulations, and in vitro experiments to elucidate the mechanisms underlying DBP-associated HNSC. Lipoprotein lipase (LPL) was identified as the sole overlapping gene between DBP-related targets and HNSC-associated genes. MR analysis supported a potential causal relationship between LPL and HNSC susceptibility. Expression profiling demonstrated tissue- and cell type-specific patterns of LPL and its dysregulation in HNSC, with associations to tumor stage and prognosis. Genomic analyses revealed that LPL alterations were infrequent and mainly driven by copy number loss. LPL expression positively correlated with immune and stromal infiltration. Enrichment analyses implicated immune regulation and PI3K-AKT signaling. Molecular simulations showed stable DBP-LPL binding. Functionally, DBP promoted SCC9 proliferation and reduced LPL expression, and was associated with transcriptional changes in PI3K-AKT-mTOR-related genes, whereas LPL restoration mitigated these effects. These findings reveal a novel DBP-LPL axis in HNSC. Show less

Here, we aimed to assess the relation of CTRP4 levels in serum and perivascular adipose tissue (PVAT) with coronary artery disease (CAD), and investigate the effect of CTRP4 on atherosclerosis and the underlying mechanisms. CTRP4 levels were examined in serum and epicardial adipose tissue (a major PVAT) from patients with CAD. Atherosclerotic lesions were analysed in CTRP4 CTRP4 levels were lower in serum and epicardial adipose tissue of patients with CAD compared to non-CAD controls. CTRP4 knockout promoted atherosclerosis in ApoE Decreased CTRP4 levels in serum and epicardial adipose tissue are associated with CAD in patients.

The apolipoprotein E ε4 (APOE ε4) allele is a major genetic risk factor for Alzheimer's disease, but its relevance to cognition in intracranial atherosclerosis (ICAS) remains unclear. We investigated the association between APOE ε4 and cognition in ICAS. Baseline data from a multicenter cohort were analyzed. Patients with radiologically confirmed ICAS underwent APOE genotyping, plasma biomarker assays, magnetic resonance imaging assessment of cerebral small vessel disease (CSVD) and brain atrophy, and standardized cognitive testing. Among 409 patients (mean age 60 years, 55% male), 16% carried APOE ε4. Carriers showed more frequent cognitive impairment (63% vs 48%), greater stenosis burden, and lower plasma amyloid beta (Aβ)42/40 ratios, whereas other Alzheimer's biomarkers, CSVD burden, and atrophy scores showed no difference. After adjustment, APOE ε4remained associated with cognitive impairment (odds ratio [OR] 1.86). The association was pronounced in women (OR 4.43) but absent in men. APOE ε4 is linked to cognitive impairment in ICAS, particularly in women, through mechanisms beyond Alzheimer's pathology. In patients with ICAS, cognitive impairment was more prevalent in carriers than in non-carriers. Carriers showed greater stenosis burden and lower plasma Aβ42/40 ratios. After full adjustment (stroke, CSVD, and AD biomarkers), APOE ε4 remained associated with cognitive impairment. Female carriers had substantially higher odds of cognitive impairment. Show less

Lecanemab is an anti-Aβ antibody approved in China for mild cognitive impairment (MCI) and mild dementia. Real-world application requires comprehensive assessment beyond MMSE scores, considering factors like ARIA risk. This single-center, real-world study aims to evaluate its efficacy in an expanded population, observe biomarker changes, and assess its safety profile in clinical practice. We recruited adults aged 40-90 with early AD from the PUMCH Dementia Cohort. A total of 42 patients received lecanemab treatment, of whom 29 completed the 6-month treatment evaluation. Participants had confirmed amyloid and tau pathology and met clinical criteria (CDR ≤ 1, CDR-SB ≤ 8and MMSE ≥ 18). Comprehensive assessments included neuropsychological testing, CSF and plasma biomarkers (Lumipulse G1200), multi-sequence 3T MRI (volumetric and ALPS index analysis), and amyloid/tau PET imaging (Centiloid quantification). All were monitored for adverse reactions. Matched control groups (matched for sex, age, APOE genotype, disease severity, and baseline therapy) were established for comparison of longitudinally changes in cognitive function, daily living ability and structure MRI. Treatment was effective even for patients with lower MMSE scores but still classified as having mild dementia by CDR. A significant median Centiloid reduction of 30.9 was observed, with a 24.1% amyloid PET negativity rate after six months. While scores on cognitive and functional scales (CDR-SB, ADL) significantly worsened, indicating disease progression, the rate of progression was significantly slower compared to the control group. Structural MRI showed significant volume reduction in multiple brain regions and increased ventricular volume post-treatment, with no statistically significant change in the ALPS value. The rate of brain volume reduction is faster than that in the control group. Plasma biomarker dynamics (Aβ This study confirms the clinical efficacy, biomarker changes, and safety profile of lecanemab treatment over a 6-month period, demonstrating its positive therapeutic value and a favorable safety profile in the Chinese population with AD.

This study aims to demonstrate the effect of toadflax (bufalin) on erlotinib resistance in nonsmall cell lung cancer (NSCLC) by inhibiting the fibroblast growth factor receptor (FGFR). The microfluidic mobility transferase and caliper mobility-shift assays were employed to detect the FGFR inhibition by bufalin and the binding reversibility. Further, the inhibitory effects of bufalin were determined in HCC827 and HCC827/ER cells in vitro , investigating relative FGFR overexpression by quantitative reverse transcriptase-PCR (RT-qPCR) and FGFR downstream proteins, that is, FGFR substrate 2 (FRS2), extracellular signal-regulated kinase (ERK), and S6 by western blot analysis. Finally, HCC827/ER-inoculated xenograft tumors were constructed to observe the effects of bufalin and bufalin + erlotinib intervention on tumor growth. Bufalin inhibited FGFR by reversibly binding to FGFR1. In addition, the western blot analysis indicated a significant reduction in the expression levels of FGFR, FRS2, ERK, and S6 proteins in HCC827 and HCC827/ER cells, increasing the expression levels of apoptotic caspase-3 and poly-(ADP-ribose) polymerase proteins. Bufalin + erlotinib combination significantly inhibited the apoptosis of HCC827/ER cells and subsequent tumor growth in vivo . In addition, FGFR overexpression significantly reversed the sensitivity of bufalin to HCC827/ER cells, promoting the value-addition of HCC827/ER cells. Further, bufalin + erlotinib significantly reduced the growth of erlotinib-resistant HCC827/ER tumors, induced apoptosis, and inhibited the expression of FGFR and p-ERK proteins. These findings indicated that bufalin could reverse the erlotinib resistance in NSCLC by inhibiting the FGFR expression. Show less

This network meta-analysis (NMA) evaluated four novel proprotein convertase subtilisin/kexin type 9 (PCSK9) monoclonal antibodies for hypercholesterolemia management, comparing their lipid-lowering efficacy and safety. We systematically identified randomized controlled trials employing the frequentist NMA method to assess reductions in low-density lipoprotein cholesterol (LDL-C), apolipoprotein B (ApoB), and lipoprotein (a) (Lp[a]), alongside treatment-emergent adverse events (TEAEs) and serious TEAEs. A total of eight trials with 3,975 Chinese patients were included. Ongericimab 150 mg every 2 weeks (Q2W) ranked first in all efficacy outcomes, demonstrating pronounced effects in LDL-C, ApoB, and Lp(a) reduction versus placebo, with mean differences of -74.21% (95% confidence interval [CI]: -79.69% to -68.73%), -64.36% (95% CI: -68.58% to -60.13%), and -50.93% (95% CI: -56.24% to -45.61%), respectively. All interventions exhibited safety profiles comparable with placebo, with no significant differences in TEAEs or serious TEAEs incidence. The analyses suggested that a portion of the evidence base was robust and reliable. These findings positioned ongericimab 150 mg Q2W as a clinically optimal PCSK9 inhibitor with robust lipid-lowering capacity. The results highlight the potential of next-generation PCSK9 monoclonal antibodies, particularly in East Asian populations, while underscoring the need for large-scale multinational trials to validate ethnic-specific responses.
