Mind-body exercises (MBEs), including Tai Chi (TC), Qigong (QG), Yoga (YG), and Mindfulness-Based Stress Reduction (MBSR), show promise in neuropsychiatric rehabilitation by modulating neuroinflammation. This study systematically examines the effects of MBEs on neuroinflammation-related biomarkers in neuropsychiatric disorders, aiming to identify optimal modalities, dosages, and key moderators. Databases were systematically searched for eligible RCTs from inception until February 2025. Data were analyzed using R packages (" Twenty-nine RCTs involving 2253 participants were included. MBEs significantly reduced IL-6 [standardized mean difference (SMD) = -0.47] and IL-1β [SMD = -0.90], while increasing BDNF [SMD = 1.08] and IL-10 [SMD = 0.87]. Effects on TNF-α [SMD = -0.33] and CRP [SMD = -0.12] showed a non-significant trend toward benefit. Dosages between 600 and 1000 MET-min/week yielded the most pronounced anti-inflammatory effects. Network meta-analysis ranked TC and MBSR as the most effective for reducing proinflammatory cytokines, while QG showed the greatest benefits for neurotrophic outcomes. Participant characteristics (age, population, clinical conditions) and MBE parameters (duration, frequency, session length) significantly moderated neuroprotective effects. MBEs effectively reduce proinflammatory cytokines (IL-1β, IL-6) and enhance anti-inflammatory cytokine (IL-10) and neurotrophic factor (BDNF) in neuropsychiatric disorders. The optimal dosage ranges from 600 to 1000 MET-min/week. Given the impact of participant characteristics and MBE parameters, personalized prescriptions may enhance clinical outcomes and long-term neuroprotective effects. Show less

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

Early pregnancy loss (EPL), a spontaneous death of the embryo or foetus occurring within the first trimester, is a major challenge for human reproduction with profound adverse consequences for women's health. Currently, reliable blood-based biomarkers for EPL remain limited. Therefore, there is an urgent need to discover novel biomarkers for EPL using a multi-omics-based approach to facilitate early detection and timely management. In the discovery cohort, 40 patients with EPL and 40 healthy pregnancies (HP) at 7-13 weeks of gestation were enrolled. Serum proteins and metabolites were assayed by Olink® technology and ultra-performance liquid chromatography coupled to tandem mass spectrometry (UPLC-MS/MS), respectively. Biomarkers were defined by false discovery rate (FDR) < 0.05 and fold change (FC) > 1.2. Random forest (RF) and logistic regression (LR) models incorporating selected biomarkers were employed to develop diagnostic models for EPL. In the external validation cohort, we prospectively enrolled 142 pregnancies at 7-10 gestational weeks, including 47 subjects who subsequently developed EPL and 95 pregnancies with full-term birth. Serum levels of selected biomarkers were quantified by ELISA. The combined proteomics and metabolomics screening identified 26 proteins and 21 metabolites significantly changed in the EPL group and tightly associated with EPL-related clinical phenotypes, with functional enrichment in immunoregulation and lipid oxidation processes. Moreover, integrating serum levels of angiopoietin-like 4 (ANGPTL4), programmed death-ligand 1 (PD-L1), neutrophil%, and lymphocyte% achieved an AUC of 0.944 (95% CI: 0.835-1.000) in the random forest model and 0.954 (95% CI: 0.875-1.000) in the logistic regression model to discriminate EPL from HP. Importantly, this four-biomarker model achieved an AUC of 0.857 (95% CI: 0.747-0.968) in the random survival forest model and a C-index of 0.804 (95% CI: 0.685-0.973) in the validation cohort for EPL prediction. Our integrative omics study reveals a panel of potential circulating biomarkers for EPL, which further offer mechanistic insights into EPL pathogenesis, including impaired maternal immune tolerance and dysregulated lipid metabolism pathways. Moreover, the newly identified biomarkers exhibit promising diagnostic and predictive performance for EPL, underscoring its clinical translational value for human reproduction and maternal-foetal health.

Protein feed resource shortage is a major constraint to the sustainable development of the livestock industry and a bottleneck problem hindering the growth of the Tibetan pig industry in China's Qinghai-Tibet Plateau region. Walnut meal, rich in protein, holds promise as a substitute for soybean meal. However, the effects and underlying mechanisms of walnut meal substitution on Tibetan pigs in Diqing remain unclear. The study showed that substituting 50% of soybean meal with walnut meal in the diet of Diqing Tibetan pigs significantly reduced backfat thickness and increased intramuscular fat content ( This study reveals that walnut meal can serve as a substitute for soybean meal, and a 50% substitution ratio is conducive to intramuscular fat deposition in Diqing Tibetan pigs. The findings provide valuable insights for the development and application of unconventional protein feed resources, and offer new perspectives for the production of marbled pork. Show less

Current infant formulas lack the native multilayer structure of breast milk fat globule membrane (MFGM), impacting lipid digestion. In this study, the inner layer material and concentration of the biomimetic fat globule membrane were optimized by comparing particle size, Zeta-potential and interface protein load. It was found that compared with sodium caseinate (CN) and whey protein (WP), when the lactoferrin (LF) concentration was 2 %, the particle size was lower (277.85 ± 6.15 nm) and Zeta-potential value was higher (19.67 ± 1.27 mv). Using milk phospholipid (MPL) as the outer layer material, when the MPL concentration was 2 %, the emulsion had a smaller particle size (291.33 ± 1.15 nm) and a better stability (10.22 ± 0.62 %). Therefore, the biomimetic multilayer membrane was constructed by electrostatic layer-by-layer deposition of 2 % LF and 2 % MPL. Combining Fluorescence and Fourier transform infrared spectroscopy (FTIR), the interaction between LF and MPL molecules in the LF-MPL multilayer structure is primarily a spontaneous, endothermic process driven by hydrophobic forces, exhibited superior stability (except thermal stability) than LF monolayer membrane. The results of in vitro digestion showed that compared with LF, WP and WP-MPL emulsions, LF-MPL emulsions had the highest free fatty acid (FFA) release rate of 69.97 %. LF-MPL enhanced gastric stability and promoted intestinal lipolysis and improved the degree of lipid digestion. In addition, LF-MPL promoted the absorption and utilization of triglyceride (TAG) in cells and animals, and secretion and upregulated lipid absorption genes (FATP4, DGAT1, APOB, APOA4, MTTP). These findings demonstrate that biomimetic LF-MPL multilayers improve lipid digestion, absorption, and bioavailability, providing a theoretical basis for designing more breast milk-like infant formulas.

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.

Dysregulation of low-density lipoprotein (LDL) cholesterol is strongly correlated with the risk of metabolic dysfunction-associated steatotic liver disease. Endogenous molecules targeting LDL clearance play crucial roles in the progression of liver steatosis. Human cathelicidin LL-37 can form complexes with lipoproteins, but whether these complexes regulate lipoprotein-driven cholesterol metabolism is not clear. Here, we find that cathelicidin LL-37 binds to LDL via apolipoprotein (Apo)B-100 domains, enhancing the solubility of ApoB-100 and inhibiting the modifications and aggregation of LDL. LL-37-LDL interaction promotes LDL uptake through LDL receptor (LDLR) both in hepatocytes and macrophages. This interaction also promotes LDL cholesterol clearance by facilitating cholesterol excretion and cholesterol efflux. In Apoe Show less

This study explored the therapeutic potential of puerarin in diabetic atherosclerosis (DA) by targeting endothelial dysfunction and lipid metabolism in apolipoprotein E (APOE)-/- mice. In vitro, human aortic endothelial immortalized cells cultured under high glucose conditions were treated with puerarin. Cell viability was quantified using cell counting kit-8 (CCK-8) assay. Apoptosis rates were measured via Annexin V/PI flow cytometry. Lipid accumulation was assessed through Oil Red O staining. iNOS levels were detected by ELISA. In vivo, diabetic APOE-/- mice fed a high-fat diet received daily puerarin administration. Aortic collagen deposition was evaluated using Masson trichrome staining. Plaque burden was analyzed via hematoxylin-eosin staining. Serum lipid profiles, including low-density lipoprotein cholesterol and high-density lipoprotein cholesterol, were determined by enzymatic assays. Follistatin-like 1 (Fstl1) protein expression and downstream inflammatory mediators were examined through Western blot and immunofluorescence. Puerarin significantly improved endothelial cell survival and reduced apoptosis under high glucose. Lipid droplet formation decreased alongside iNOS suppression. In diabetic mice, puerarin attenuated aortic plaque area and collagen content while improving dyslipidemia. Fstl1 expression and associated inflammatory markers were downregulated. Puerarin alleviates DA progression through dual modulation of endothelial protection and Fstl1-mediated inflammatory pathways. Show less

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

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. In vitro, VRBPC effectively restored endothelial phenotype, reduced aberrant migration, and diminished foam cell formation alongside pro-inflammatory cytokine secretion. In ApoE Show less

Oxidised 1-palmitoyl-2-arachidonoyl-sn-glycero-3-phosphorylcholine (oxPAPC), dendritic cells (DCs), and long non-coding RNAs (lncRNAs) play crucial roles in atherosclerosis (AS). This study aimed to determine whether oxPAPC-induced DC-derived lncRNAs contribute to AS and to elucidate the underlying regulatory mechanisms. DCs were treated with increasing oxPAPC concentrations to assess transcriptomic changes. RNA sequencing was used to identify differential expression of lncRNAs. ChIP-Seq and RNA pull-down assays were used to assess direct binding between lncRNA CYP1B1-AS1 and NFATC2. The association between CYP1B1-AS1 and CYP1B1 was assessed using Pearson's correlation analysis. Elevated serum oxPAPC levels were confirmed in patients with coronary heart disease. In vitro, sustained oxPAPC stimulation activated the TLR4-MD2 pathway in DCs. CYP1B1-AS1 was identified as the key oxPAPC-induced DC-derived lncRNA, with Gm33055 as its murine homologue. RNA sequencing revealed oxPAPC-driven alterations in DC chemotaxis, differentiation, and lymphocyte activation. Analysis of human atherosclerotic plaque-derived DCs showed significant CYP1B1-AS1 upregulation. Gm33055 enhanced Cyp1b1 expression in murine DCs. Mechanistically, oxPAPC promoted NFATC2 nuclear translocation. NFATC2 binds to the CYP1B1-AS1 promoter, whereas CYP1B1-AS1 directly interacts with NFATC2, forming a positive regulatory loop.

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.

Disruption of circadian rhythms is increasingly recognized as a contributor to cognitive dysfunction, but its role in gestation-associated cognitive changes remains unexplored. Here we combine human cognitive screening with a comprehensive longitudinal mouse model to investigate whether gestational cognitive impairment and postpartum recovery are coupled with disruption and restoration of hippocampal circadian rhythms. Cognitive function was assessed in pregnant and postpartum women using the Montreal Cognitive Assessment (MoCA) and Mini-Mental State Examination (MMSE). In mice, four reproductive stages were compared: control, gestation, 1 month postpartum, and 3 months postpartum. Serum gonadotropins and sex hormones levels were quantified using ELISA. Home-cage locomotor activity was recorded over 48 h under a 12 h:12 h light-dark cycle. Hippocampal-dependent memory was evaluated using the novel object recognition test and Barnes maze at Zeitgeber times ZT6 (day) and ZT18 (night). Hippocampal amyloid β (Aβ) deposition was visualized via immunofluorescence; protein expression of amyloid precursor protein (APP), β-site amyloid precursor protein cleaving enzyme-1 (BACE1), and phosphorylated tau was measured by Western blots. Hippocampal clock gene expression was quantified by RT-qPCR at six time points; circadian parameters (mesor, amplitude, acrophase) were derived by cosinor analysis and compared between groups. Human cognitive screening confirmed modest gestational decline with postpartum recovery. In mice, gestation disrupted daily locomotor activity rhythms and reduced nocturnal preference; both partially recovered by 1 month and fully by 3 months postpartum. Behaviourally, pregnancy impaired the normal day-night difference and performance in novel object exploration and Barnes maze, which recovered progressively. At the molecular level, gestation increased hippocampal APP and BACE1 expression, elevated Aβ42 deposition, and induced tau hyperphosphorylation at multiple sites-hallmarks of Alzheimer's disease-related pathology. These alterations partially reversed by 1 month postpartum and normalized by 3 months. Hippocampal clock genes maintained 24 h rhythmicity, but gestation induced gene-specific phase shifts, amplitude reductions, and mesor alterations. These parameters showed gradual, gene-dependent normalization postpartum. Gestational cognitive impairment and postpartum recovery are associated with reversible disruption and restoration of both hippocampal circadian rhythms and Alzheimer's disease-related molecular pathology. These findings are correlational in nature and provide a foundation for future causal investigations. Show less

Beta-site APP-cleaving enzyme 1 (BACE1), a critical rate-limiting enzyme that synthesizes β-amyloid peptide (Aβ), is an important marker of early pathological changes in Alzheimer's disease (AD). Early small plaques cannot be accurately detected using traditional Magnetic resonance imaging (MRI) probes. Therefore, magnetic resonance tuning (MRET) and susceptibility weighted imaging (SWI)-based smart responsive MR nanoprobes are designed to achieve the sensitive detection of BACE1 and Aβ plaques. This probe is modified with a blood-brain barrier-penetrating targeting peptide that enables its reach to the AD microenvironment. The enhancement of T1WI signals owing to the MRET effect caused by the separation of probes in response to BACE1 is used to reflect real-time BACE1 changes. When Aβ plaques are present, the remaining probes that bound around Aβ plaques underwent in situ thiol cross-linking under the action of peroxynitrite (ONOO Show less

Diabetic foot ulcer (DFU), a severe complication of diabetes, impose substantial global health burdens. Dampness-heat syndrome (DHS), a common syndrome in traditional Chinese medicine (TCM), is highly prevalent among DFU patients and closely correlated with treatment response and prognosis. However, the molecular biomarkers associated with DFU in patients with DHS remain poorly understood. Serum 4D-data-independent acquisition (DIA) proteomics was performed on 16 DFU-DHS patients and six healthy controls (HCs). Differentially expressed proteins (DEPs) were screened by |fold change (FC)| > 1.2 and p < 0.05. Gene Ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG), and protein-protein interaction (PPI) analyses were conducted. Key biomarkers were validated via enzyme-linked immunosorbent assay (ELISA) in 28 independent DFU-DHS cases. A total of 201 DEPs were identified between DFU-DHS patients and HCs. Bioinformatics revealed DEPs enriched in lipid metabolism (high-density lipoprotein [HDL] remodeling and cholesterol metabolism) and complement-coagulation cascades. PPI network analysis revealed a core functional module centered on four proteins, APOA1, LCAT, PLTP, and CETP. ELISA validation confirmed the significant dysregulation of these four apolipoproteins in the independent DFU-DHS cohort (all p < 0.05 vs. HCs). The combination of the biomarkers APOA1, LCAT, PLTP, and CETP exhibited a high diagnostic efficacy for DFU-DHS, with an area under the curve (AUC) of 0.9672 based on receiver operating characteristic (ROC) analysis. To our knowledge, this is the first study to employ 4D-DIA proteomics on DFU-DHS. We identified four serum biomarkers (APOA1, LCAT, PLTP, and CETP) linked to dysregulated cholesterol metabolism in DFU-DHS patients, which show diagnostic potential and provide insights for integrating TCM syndrome differentiation with precision medicine.

Papillary thyroid carcinoma (PTC) is the most common form of thyroid cancer, with the majority of cases driven by genetic alterations that activate the MAPK signaling pathway. The BRAF V600E mutation is the most frequent alteration, while BRAF fusions are relatively rare but increasingly recognized as oncogenic drivers. These fusions typically involve the loss of BRAF's autoinhibitory N-terminal domain, leading to constitutive MAPK pathway activation. Here, we report a novel SORBS2::BRAF fusion in a case of PTC, further expanding the spectrum of BRAF alterations in thyroid cancer. A 32-year-old male was incidentally found to have a left thyroid nodule during a routine physical examination. Follow-up examinations revealed changes in the nodule's characteristics, prompting fine-needle aspiration biopsy, which identified atypical follicular epithelial cells suggestive of papillary thyroid carcinoma. Histopathological examination confirmed the diagnosis, and next-generation sequencing (NGS) revealed a novel in-frame fusion between SORBS2 exon 18 and BRAF exon 9. The resulting fusion protein retains the BRAF kinase domain while replacing its autoinhibitory domains with those of SORBS2. RT-PCR and Sanger sequencing confirmed the presence of the SORBS2::BRAF fusion. Quantitative PCR profiling of MAPK transcriptional output genes (DUSP6, CCND1, ETV4, c-Myc, and c-FOS) revealed marked upregulation in the tumor versus adjacent normal tissue, providing functional evidence for pathway activation. The SORBS2::BRAF fusion has not been previously reported in PTC or any other tumor type. Given the deletion of BRAF's inhibitory domain, this fusion likely acts as a tumor driver through constitutive activation of the MAPK pathway. This case underscores the importance of molecular diagnostics in identifying rare genetic alterations and highlights the need for further research into targeted therapies for BRAF fusion-driven cancers. The discovery of this novel fusion expands our understanding of the molecular landscape of PTC and provides a foundation for future therapeutic development. Show less

The aim of this study was to investigate the impact of interleukin-27 (IL- 27) gene polymorphism and additional interactions with environmental factors on non-small cell lung cancer (NSCLC) risk based on a Chinese population. SNPStats online software ( http://bioinfo.iconcologia.net/SNPstats ) was used for Hardy-Weinberg equilibrium (HWE) testing. Stratified analysis was performed by logistic regression model to examine the impact of IL- 27 gene SNPs and environmental factors, and additional gene-environment interaction on NSCLC risk. Logistic regression analysis showed a significant association between rs153109, rs181206 and increased NSCLC risk. However, no significant relationship was found between NSCLC risk and rs17855750 or rs40837 genotype with minor allele. Logistic regression also indicated a significant association between smoking status or alcohol consumption and NSCLC risk in this study. We performed crossover analysis to investigate the interaction between two SNPs (rs153109 and rs181206) and two environmental factors (smoking status and alcohol consumption) using logistic regression. We found that ever or current smokers with rs153109- AG or GG genotype have the highest NSCLC risk, compared with never smokers with the AA genotype after covariate adjustment, OR (95%CI) = 3.02 (1.97-5.12), p = 0.012. However, no significant interaction effect was found between rs153109 and alcohol consumption, rs181206 and smoking, rs181206 and alcohol consumption. Our results support an important association of the IL- 27 gene rs153109, rs181206, smoking and alcohol consumption with increased NSCLC risk. We also found a significant impact of an interaction between rs153109 minor allele and ever or current smoking on NSCLC risk. Show less

Speed capability is critical for early childhood development, but troubling patterns are emerging in the motor fitness of Chinese preschoolers (3-6 years). This study investigated how compositional 24-h movement behaviours (sleep, sedentary behaviour [SB], light physical activity [LPA] and moderate-to-vigorous physical activity [MVPA]) relate to speed capability. Via compositional data analysis and isotemporal substitution modelling, we assessed relationships between 24-h movement behaviours (sleep, SB, LPA and MVPA) and speed capability in 275 preschoolers (mean age 4.98 ± 0.76 years). Participants completed 20-m sprint tests and 7-day accelerometry. Time-reallocation effects were quantified through pairwise behavioural substitutions (5- to 30-min durations), with all models adjusted for age, sex and BMI z scores (z-BMI). Higher relative MVPA time significantly predicted faster sprint times (β = -1.302, p < 0.001), while higher LPA predicted slower times (β = 1.570, p = 0.003). Reallocating 15 min from sleep, SB or LPA to MVPA reduced sprint times by 0.176, 0.201 and 0.385 s, respectively (all p < 0.05). Conversely, reallocating MVPA to other behaviours worsened performance. The effects exhibited asymmetry: displacing time away from MVPA impaired speed capability to a greater extent than equivalent gains in MVPA time improved it. MVPA is the strongest positive predictor of speed capability in preschoolers. Optimizing 24-h movement patterns by reallocating time from LPA or SB to MVPA is associated with enhanced speed performance, supporting targeted interventions for early childhood development.

To use compositional data analysis to examine the associations of daily movement behaviors with body composition, and to predict changes in body composition after reallocating time among behaviors in preschool-aged children. 268 preschoolers were included in the cross-sectional study. An accelerometer was used to assess sedentary behavior (SB), light and moderate-to-vigorous physical activity (LPA and MVPA). A parental report was used to collect sleep time. Bioelectrical impedance analysis was employed to assess body composition. Compositional linear regression analysis was employed to explore how daily movement behaviors were associated with body composition. Compositional isotemporal substitution analysis was employed to estimate changes in body composition after reallocating time among behaviors. 24-h movement behaviors composition significantly predicted fat-free mass index (FFMI), soft lean mass index (SLMI), and skeletal muscle mass index (SMMI), but not fat mass index, percent body fat, and bone mineral content index. The compositional isotemporal substitution analyses consistently showed that increasing MVPA at the expenses of SB was positively associated with FFMI (+0.328 kg/m The findings highlight the importance of MVPA in improving preschoolers' body composition. Increasing MVPA at the expenses of SB may be a strategy to improve body composition in preschoolers. Show less

The fat mass and obesity-associated (FTO) gene, though widely studied in human obesity and livestock lipid accumulation, remains poorly understood in bovine adipogenesis. This study investigated its role in bovine adipocytes via overexpression, given its high expression in Guanling cattle adipose tissue. Results demonstrated that FTO significantly increased triglyceride content, adiponectin secretion, and lipid droplet accumulation (P < 0.01). It also upregulated key adipogenic markers (PPARγ, C/EBPβ, FABP4, LPL; P < 0.05). Transcriptomic analysis revealed that FTO promotes adipocyte differentiation and lipogenesis through regulating multiple lipid metabolic pathways. These findings reveal that FTO positively regulates bovine adipocyte differentiation by modulating lipid metabolic networks, thereby filling a critical gap in the understanding of FTO-mediated lipid metabolism in ruminants.

The international consensus classification or the World Health Organization classifications underrepresented driver alterations enriched in pediatric acute myeloid leukemia (AML). To address this, we retrospectively characterized the genomic landscape of 105 pediatric patients with AML of East Asian ancestry using transcriptome and whole-exome sequencing (WES). In addition to the common recurrent fusions such as RUNX1::RUNX1T1 and CBFB::MYH11, we identified rearrangements involving KMT2A, NUP98, GLIS, as well as FLT3 and UBTF tandem duplications. The median somatic mutation rate in AML was 0.97 per megabase, as estimated by WES. Frequently mutated pathways included signaling: 68.6% (72/105), transcription: 37.1% (39/105), epigenetic regulation: 26.7% (28/105), cohesin: 7.6% (8/105), RNA binding: 3.8% (4/105), and protein modification: 5.7% (6/105). When analyzed together, high-risk genetic subtypes including GLISr, UBTF tandem duplications, PICALM::MLLT10, and HOXr were significantly associated with poorer 5 year overall survival (OS) in multivariable analysis (p-value = 0.037). Although FLT3 internal tandem duplications were significantly associated with inferior 5 year OS in univariable analysis, this effect was not significant in multivariable analysis (p-value = 0.382). Patients with RUNX1 mutations had inferior 5 year OS in multivariable analysis (p-value = 0.009). These findings suggest specific genomic alterations that may refine risk stratification and guide future therapeutic protocols in Taiwanese pediatric patients with AML. Show less

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

One of the recognized effects of systematic physical activity is the improvement of physical fitness, with a negative correlation found between physical fitness and cardiovascular and cardiometabolic risk. The purpose of this study is to analyze the influence of single nucleotide polymorphisms (SNPs) of the adenylate cyclase 3 ( In the 12-week HIIT program, a total of 237 Chinese Han college students with non-regular exercise habits were recruited, and these volunteers participated in the training three times a week.

To systematically evaluate the efficacy and safety of different combination therapies in the treatment of mania in bipolar disorder, and to provide evidence-based support for individualized clinical treatment. PubMed, Web of Science, Cochrane Library, CNKI, VIP, and Wanfang databases were systematically searched from inception to July 2025. Randomized controlled trials comparing ziprasidone or olanzapine combined with mood stabilizers (lithium carbonate or sodium valproate) for the treatment of manic episodes in bipolar disorder were included. Two reviewers independently performed literature screening, data extraction, and quality assessment. Meta-analysis was conducted using RevMan 5.4 software. A total of 10 RCTs involving 842 patients were included. Meta-analysis showed no significant difference between the two groups in overall clinical efficacy (OR = 1.18, 95% CI: 0.80-1.75, p = 0.41). Ziprasidone was superior to olanzapine in reducing YMRS scores (MD = -1.47, 95% CI: -1.97-0.96, p < 0.00001). The incidence of adverse reactions was significantly lower in the ziprasidone group compared to the olanzapine group (OR = 0.16, 95% CI: 0.08-0.31, p < 0.00001). Furthermore, ziprasidone was associated with significantly greater increases in BDNF and T Although the efficacy of ziprasidone plus mood stabilizers is comparable to that of olanzapine plus mood stabilizers in the treatment of manic episodes of bipolar disorder, ziprasidone offers advantages in improving manic symptoms (YMRS scores), reducing adverse events, and enhancing neuroendocrine indicators. It may serve as a favorable alternative in clinical practice. Further high-quality, multicenter, large-sample studies are needed to confirm its efficacy and safety. Show less

Gallbladder cancer (GBC) is a biliary tract cancer with a poor prognosis. Consistent evidence suggests that fasting has extensive antitumor effects in various cancers and influences levels of poly (rC)-binding protein 2 (PCBP2). However, whether fasting and PCBP2 are involved in GBC remains unknown. We assessed the expression of PCBP2 in GBC tumor tissues and cells. Knockdown and overexpression of PCBP2, combined with in vitro and in vivo assays using fasting mimic medium or diets, were conducted to provide functional significance. The effect of PCBP2 on glycolysis was assessed by glucose uptake, lactate production, oxygen consumption rate, and limiting glycolytic-associated enzymes (PDK1, PKM2, and HK-2). We found that fasting could inhibit glycolysis and cell migration/invasion in GBC cells and that fasting mimic diets could significantly inhibit GBC cell proliferation in a mouse xenograft model. PBCP2 was upregulated in GBC tumor tissues and cells. Moreover, PCBP2 is a key downstream target of fasting, and fasting decreases PCBP2 expression in GBC cells. PCBP2 knockdown inhibits GBC cell proliferation, migration/invasion, and glycolysis, whereas PCBP2 overexpression has the opposite effect. Through co-immunoprecipitation, we identified a physical connection between PCBP2 and the angiopoietin-like protein ANGPTL4. PCBP2 can negatively regulate the expression of ANGPTL4. Hence, fasting inhibits cell proliferation, migration/invasion, and glycolysis through PCBP2/ANGPTL4 signaling. We conclude that PCBP2 is a target of fasting and is involved in cell migration/invasion and glycolysis through the negative regulation of ANGPTL4 in GBC. PCBP2 represents a potential therapeutic target for GBC. Show less

In recent years, accumulating evidence has highlighted the critical role of miR-627-5p in the occurrence and progression of various cancers. However, its specific role and mechanism in cervical cancer (CC) remain unclear. This study aimed to elucidate the mechanism by which miR-627-5p inhibits the malignant progression of CC and assess its potential clinical implications. In C33A cells, the mRNA expression levels of ANGPTL4 and miR-627-5p were analyzed using qRT-PCR. The miR-627-5p mimics and their control (miR-NC) were transfected into C33A cells to determine whether miR-627-5p directly regulates ANGPTL4 expression. A comprehensive suite of assays, including CCK-8, migration, transwell, flow cytometry, and Western blotting, was conducted to evaluate how miR-627-5p modulates the malignant biological behavior of CC cells. Rescue experiments were performed by overexpressing ANGPTL4. In C33A cells, miR-627-5p expression was reduced, whereas ANGPTL4 expression was elevated. Further analysis confirmed that miR-627-5p negatively regulates ANGPTL4 by directly targeting its 3'-UTR. Functional assays demonstrated that miR-627-5p inhibits proliferation, invasion, migration, and epithelial-mesenchymal transition (EMT) while promoting apoptosis and S-phase arrest in C33A cells, effects that were reversed by ANGPTL4 overexpression. These findings highlight the potential of miR-627-5p as both a biomarker and a therapeutic target for CC. By inhibiting EMT and regulating ANGPTL4 expression, miR-627-5p may provide a novel avenue for improving therapeutic strategies, particularly in advanced or metastatic CC. Moreover, miRNA-based therapies, supported by advanced delivery systems such as nanoparticle carriers, could enhance the stability and precision of miR-627-5p applications. This study lays the groundwork for future research integrating miR-627-5p into precision medicine approaches for CC treatment. Show less
