Interleukin-27 (IL-27) in the pleural fluid has gained significant attention as a diagnostic biomarker for tuberculous pleural effusion (TPE); however, considerable variability exists across available studies. This systematic review and meta-analysis aimed to determine the diagnostic accuracy of IL-27 in identifying TPE. In addition, we also compared the diagnostic accuracy of IL-27 and adenosine deaminase (ADA) with a head-to-head meta-analysis. We searched the PubMed and Web of Science databases to identify diagnostic test accuracy studies evaluating the accuracy of IL-27 for diagnosing TPE. The last search date was September 2025. We extracted data from the eligible studies and constructed a two-by-two table with true positives (TP), false positives (FP), true negatives (FN), and false negatives (FN). The QUADAS-2 tool was used to assess the quality of eligible studies. A bivariate model was applied to pool sensitivity and specificity, and a summary receiver operating characteristic (sROC) curve with the area under the curve (AUC) was generated to estimate the overall diagnostic accuracy of IL-27 and ADA. A Deeks funnel plot asymmetry test was used to evaluate publication bias. Nine studies encompassing ten cohorts were included, involving 1573 patients (429 with TPE and 1144 with non-TPE). The reported AUCs for IL-27 ranged from approximately 0.73 to 0.99 across eligible studies. The pooled sensitivity and specificity were 0.94 (95% CI, 0.83-0.98) and 0.96 (95% CI, 0.89-0.98), respectively. The AUC for sROC was 0.99 (95% CI, 0.97-0.99). The pooled positive likelihood ratio was 21.97 (95% CI, 7.95-60.69), the negative likelihood ratio was 0.07 (95% CI, 0.02-0.18), and the diagnostic odds ratio (DOR) was 329 (95% CI, 72-1506). Significant heterogeneity was observed in both sensitivity (I IL-27 is a promising diagnostic marker for TPE, and its diagnostic accuracy is comparable to that of ADA. IL-27 should be used as a complementary diagnostic marker to ADA for TPE. Show less

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

As an important interface between the peripheral environment and the central nervous system, the gut microbiota varies greatly between patients or animals with Alzheimer's disease (AD) and their respective non-AD counterparts; however, it remains unexplored whether the apolipoprotein E (APOE) genotype, age, and sex may interactively influence the characteristics of gut microbiota in AD animals. APOE genotype, age, and sex were enrolled as independent variables, with genotype distinguished into APOE3 and APOE4, age into 3 and 10 months, and sex into female and male. The composition, structure, and potential functions of gut microbiota were systematically analyzed by 16S rRNA gene amplicon sequencing to evaluate the individual and interactive effects of APOE genotype, age and sex. Significant interactions were observed among APOE genotypes, ages, and sexes, with different factor combinations exhibiting distinct effect on microbiotic composition and functional potential. APOE genotype exerted the most significant influence on gut microbiota, followed by age and sex with a relatively minor effect, highlighting the dominant role of host genetic background. Functional prediction analysis indicated that the functional profiles were mainly concentrated in basic metabolic pathways, including the biosynthesis of secondary metabolites and amino acids, and carbon metabolism. APOE genotype, age, and sex are jointly associated with the structure and potential function of the gut microbiota in AD model mice. These findings provide a perspective of multi-factor interaction into the alterations in gut microbiota in AD and offer new microecological evidence for understanding APOE4-related AD susceptibility, as well as a conceptual basis for future stratified microecological intervention studies.

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

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.

Major depressive disorder (MDD) in adolescents is a critical public health concern, yet objective diagnostic biomarkers remain lacking. We conducted an integrative lipidomics study across human cohorts and a chronic unpredictable mild stress (CUMS) rat model. Targeted UPLC-MS/MS profiling was applied to a training cohort (95 MDD, 40 controls), and untargeted UPLC-HRMS profiling to an independent cohort (56 MDD, 37 controls). Candidate biomarkers were identified using univariate tests, partial least squares discriminant analysis, and three feature-selection methods (Boruta, LASSO, RFE), with predictive performance evaluated by cross-validation and external replication. Translational relevance was examined in CUMS rats through behavioral assays and lipidomic profiling of serum and brain tissues. Pathway enrichment and regression models explored metabolic context and clinical associations. In the training cohort, we found that 244 lipids were significantly altered, highlighting altered glycerophospholipid, glycerolipid, and sphingolipid metabolism. A 29-lipid panel achieved 90.4% cross-validation accuracy, while a reduced 7-lipid subset reached 94.8%. In the validation cohort, an 8-lipid panel achieved 71.2% accuracy, and a minimal 2-lipid set-LPA(18:2) and SPH(d16:1)-reached 72.1%. Cross-species analysis confirmed consistent downregulation of SPH(d16:1) in serum of both humans and rats, and of LPC(0:0/16:0) specifically in the rat prefrontal cortex. Regression analyses linked sex, age, and anxiety severity to lipid alterations. This cross-platform, cross-species study identifies reproducible lipid signatures of adolescent MDD, highlights SPH(d16:1) and LPC(0:0/16:0) as translational biomarkers, and implicates glycerophospholipid metabolism in MDD pathophysiology, providing a foundation for biomarker-guided diagnostics and therapeutics.

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

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

Chronic pain, marked by nociceptive sensitization and maladaptive neuroplasticity, affects 30% of the global population with escalating socioeconomic burdens. Epidemiological data show a 2-3-fold increase in neuropsychiatric co-morbidities among individuals with chronic pain, where epigenetic dysregulation serves as a key mechanism linking ongoing pain to emotional disorders. This review systematically explores epigenetic signatures in supraspinal integration hubs, notably the limbic-paralimbic networks and prefrontal regulatory circuits. The identified epigenetic signatures encompass dysregulation of DNA methyltransferases (DNMTs), RNA modifications, histone post-translational modifications and locus-specific alterations, including aberrant methylation at the brain-derived neurotrophic factor (BDNF), opioid μ receptor and transient receptor potential ankyrin 1 (TRPA1) gene loci. Additionally, they involve dysfunction of the glucocorticoid receptor (GR)/corticotropin-releasing factor (CRF) axis via epigenetic modulation. Building on these findings, we evaluate therapeutic strategies addressing epigenetic dysregulation. While preclinical data demonstrate the efficacy of histone deacetylase (HDAC) and DNMT inhibitors, clinical translation faces significant barriers, including limited blood-brain barrier permeability. Notably, our analysis highlights the benefits of combining pharmacological interventions with non-invasive neuromodulation for enhanced co-morbidity management. Looking forward, this review proposes innovative approaches that leverage CRISPR-based chromatin editing platforms, biomimetic nanocarriers for neuron-specific delivery and closed-loop neuromodulation integrating real-time biomarker feedback, collectively establishing a precision medicine framework for pain or neuropsychiatric co-morbidities.

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

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

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

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.

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

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

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

Although immune-mediated diseases (IMDs) and major depressive disorder (MDD) commonly co-occur, the bidirectional relationship between them remains to be fully elucidated. Using data from the prospective UK Biobank cohort, we evaluated the bidirectional associations by time-varying Cox proportional hazards regression models and assessed shared genetic architecture using genome-wide association study summary statistics. Additionally, we employed collagen-induced arthritis (CIA) and chronic social defeat stress (CSDS) mouse models to investigate the relationship between rheumatoid arthritis (RA) and depression.

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.

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

ApoB (apolipoprotein B)-containing lipoproteins are causal risk factors for atherosclerotic coronary artery disease (CAD). Since human cathelicidin LL-37 binds to ApoB-100 in this pathological context, we investigated whether the circulating LL-37-ApoB-100 complex could serve as a biomarker for CAD. We performed surface plasmon resonance and protein-protein docking to demonstrate the direct LL-37-ApoB-100 interaction. We developed a specific polyclonal antibody against the complex and measured its levels in human atherosclerotic plaques and plasma, as well as in We identified that LL-37 directly interacted with multiple distinct binding sites on ApoB-100. Plasma levels of LL-37-ApoB-100 complex were significantly elevated in human patients with atherosclerosis. Consistently, levels of this complex were positively correlated with atherosclerotic plaque area in Circulating LL-37-ApoB-100 levels are strongly associated with angiographically documented CAD, highlighting LL-37-ApoB-100 as an independent predictor for CAD.

p-Synephrine (p-Syn), a natural alkaloid isolated from Citrus aurantium L., promotes fat oxidation and is therefore widely used as a weight loss dietary supplement. It was recently reported to exert a potent antidepressant effect. However, its molecular targets remain undefined. Gastrodin (Gas), extracted from Gastrodia elata Blume, exerts antidepressant effects by targeting Melatonin Receptor 1A (MT This study aimed to evaluate whether MT Network pharmacology was applied to predict potential targets and associated signaling pathways for p-Syn and Gas. Molecular Docking simulations were employed to predict the possible binding sites of MT Using a network pharmacology approach and in vitro assays, we found that both p-Syn and Gas bind to MT1, activate the ERK/CREB signaling pathway, and up-regulate BDNF. In vivo assays showed that p-Syn alleviated Reserpine (Res)-induced depression-like symptoms in AB zebrafish larvae and C57 mice. Furthermore, p-Syn and Gas showed a remarkable synergistic effect. This study identifies a novel target for p-Syn and provides new insights into the antidepressant mechanisms of p-Syn and Gas that may contribute to the clinical application of these compounds in the development of new drugs for the treatment of depression.

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

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

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