Based on Traditional Chinese Medicine (TCM) theory, the efficacy and mechanism of Ginger juice processed Ziziphi Spinosae Semen (GJPZSS) for treating insomnia, particularly stress-related types, were investigated to provide empirical evidence. An insomnia model was induced in mice by DL-4-chlorophenylalanine (PCPA) and chronic tail clamping. The sedative effect was evaluated by behavioral tests. Serum components from GJPZSS were analyzed by UHPLC-Q-TOF-MS/MS, and 64 potential targets were identified. The cAMP signaling pathway was enriched as the core pathway by Kyoto Encyclopedia of genes and genomes (KEGG) analysis and was validated by molecular docking. GJPZSS was demonstrated to prolong sleep time, reduce immobility time, increase 5-hydroxytryptamine (5-HT) and gamma-aminobutyric acid (GABA) levels, decrease hypothalamic-pituitary-adrenal (HPA) axis levels, and suppress neuronal death. The reduction of the cyclic adenosine monophosphate (cAMP), protein kinase A (PKA), cAMP-response element binding protein (CREB) and brain-derived neurotrophic factor (BDNF) in the brain was also significantly inhibited. It was concluded that the sleep-improving effect of GJPZSS was mediated through the regulation of the HPA axis and the cAMP/PKA/CREB/BDNF signaling pathway. Show less

MYBPC3 mutations are the leading cause of hypertrophic cardiomyopathy. Here, to study the pathogenesis of hypertrophic cardiomyopathy, we created a MYBPC3 knockout (KO) model using human induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs). MYBPC3-deleted hiPSC-CMs revealed the characteristics of heart failure, which exhibited increased contractility at 30 days but decreased at 40 days. Furthermore, at 40 days, it also shows abnormal calcium handling, increased ROS levels, and mitochondrial damage. Further RNA sequencing revealed that the oxidative stress pathway was aberrant, in addition to alterations linked to hypertrophic cardiomyopathy. Moreover, after adding melatonin to hiPSC-CMs at 30 days, MYBPC3-deleted hiPSC-CMs showed restored calcium handling capacity, decreased ROS levels, and improved myocardial contractility. In summary, reducing ROS can improve the phenotype of hypertrophic cardiomyopathy. Show less

Cerebral palsy (CP), the most prevalent pediatric motor disorder with significant cognitive comorbidity (> 50%), lacks therapies addressing both impairments in moderate-to-severe cases. This study demonstrates that human umbilical cord mesenchymal stem cell-derived exosomes (hUCMSC-Exos) exert profound therapeutic effects in a rat model of moderate-to-severe CP established via bilateral carotid artery occlusion with hypoxia. Intravenously administered hUCMSC-Exos displayed sustained brain retention and significantly restored motor coordination and cognitive function. The recovery was primarily mediated through enhanced remyelination driven by promoted oligodendrocyte maturation and differentiation (elevated oligodendrocyte lineage transcription factor 2 and myelin basic protein). Concurrently, the treatment attenuated key pathological processes involving sustained neuroinflammatory responses (reduced ionized calcium-binding adapter molecule 1, tumor necrosis factor-α, and interleukin-6) while elevating brain-derived neurotrophic factor. Our findings establish hUCMSC-Exos as a promising dual-modality therapy for moderate-to-severe CP, mechanistically linked to robust remyelination and coordinated modulation of core disease mechanisms.

Brusatol (BRU), a major bioactive quassinoid isolated from Brucea javanica, has shown potential in the treatment of inflammatory diseases. As mitochondrial dysfunction has been implicated in chronic inflammatory disorders, modulation of mitochondrial homeostasis may offer a potential approach for the treatment of rheumatoid arthritis (RA) and atherosclerosis (AS). To develop a novel BRU derivative through rational modification at the C11‑hydroxyl group and to compare the therapeutic effects of BRU and its derivative BRUD in experimental models of RA and AS, with particular focus on mitochondrial regulation and Drp1-associated signaling. This study combined in vivo and in vitro experiments to evaluate the pharmacological effects of BRU and BRUD and investigate the underlying mechanisms. The chemical constituents of BRU and BRUD were confirmed by HPLC and NMR spectroscopy ( In vivo studies demonstrated that both compounds ameliorated joint damage in CIA rats and reduced atherosclerotic lesion burden in ApoE These findings suggest that BRUD exhibits improved activity compared with BRU in RA and AS models, with protective effects associated with modulation of mitochondrial dysfunction, supporting its further evaluation as a lead compound.

The melanocortin-4 receptor (MC4R), a key regulator of energy balance and feeding behavior, plays a critical role in sheep growth. Herein, we identified a naturally occurring conserved functional SNP (g.59480661G > A, E100K, P.Glu100Lys) in the sheep MC4R gene. Using the Kompetitive Allele Specific PCR method, we detected this mutation in 2,151 sheep from six different breeds. Association analysis revealed that this mutation affects the growth traits of Luxi Blackhead sheep, and the individuals with AA (K100) genotype exhibited superior growth performance compared to the GG (E100) genotype. Additionally, whole-genome sequencing data from 49 sheep breeds, totaling 968 individuals, showed a higher mutation frequency of this variant in some large-sized sheep breeds. Functional studies demonstrated that the E100K mutation does not affect protein localization or transport but reduces surface and total protein expression. The mutated receptor exhibited decreased basal activity and reduced binding efficiency with agonists (α-MSH and β-MSH), resulting in a partial loss of function. Transcriptomic analysis indicated that this mutation affects downstream pathways, including osteoclast differentiation and the MAPK signaling pathway, which may influence growth regulation associated with the E100K mutation. Collectively, these findings underscore the substantial role of the partial loss-of-function MC4R E100K mutation in regulating growth traits in sheep. Show less

Esophageal squamous cell carcinoma (ESCC) remains a major health burden, particularly in Asia, with poor patient prognosis despite advancements in radiotherapy, chemotherapy, and immunotherapy. The marked inter-patient and intra-tumor heterogeneity of ESCC underscores the need for molecularly informed diagnostic and therapeutic strategies. Recent high-throughput omics technologies, including genomics, transcriptomics, proteomics, and metabolomics, have substantially advanced our understanding of ESCC biology. Genomic profiling has revealed recurrent alterations such as TP53 and NOTCH1 mutations, as well as actionable targets including PIK3CA, FGFR1, and SOX2 amplifications, which provide new opportunities for precision therapy. Epigenomic and transcriptomic analyses have identified methylation-based early detection markers (e.g., PAX9, SIM2) and immune-related transcriptomic subtypes associated with prognosis and immunotherapy responsiveness. Proteomic and metabolomic studies have further uncovered cell cycle and spliceosome pathway activation and altered lactate metabolism, offering additional biomarker and therapeutic insights. In this review, we synthesize these multi-omics advances and highlight how they collectively inform improved diagnostic, prognostic, and therapeutic strategies for ESCC. Despite these developments, the clinical translation of multi-omics findings remains limited due to the lack of standardized analytical pipelines, insufficient multi-center validation, and the high cost and technical complexity of integrating multi-omics data into routine clinical workflows. Future research integrating artificial intelligence with multi-omics data holds promise for enhancing diagnostic accuracy and enabling more precise therapeutic decision-making in ESCC. Show less

Families with children diagnosed with autism spectrum disorder (ASD) often encounter significant challenges, manifesting in elevated stress levels and compromised physical and mental well-being. This study employed Latent Profile Analysis (LPA) to comprehensively examine family resilience attributes among 328 Chinese parents of children with ASD. Drawing on Walsh's family resilience framework and the Double ABCX stress-adaptation model, the research examined how protective factors (social support, posttraumatic growth) and risk factors (family stressors) distinctively characterize resilience profiles and predict profile membership, alongside sociodemographic correlates. Through rigorous statistical analysis, the following three distinct family resilience profiles emerged: adversity (32.31%; characterized by low resilience), ordinary (46.65%; demonstrating moderate resilience) and growth (21.03%; exhibiting high resilience). Critically, the findings revealed that higher family income, perceived social support and posttraumatic growth were associated with higher family resilience, while family stressors were associated with lower family resilience. These insights underscore the importance of developing targeted, personalized intervention strategies that can effectively enhance familial coping mechanisms and psychological adaptation for families navigating the complex challenges of ASD.

The protein corona formed upon systemic administration critically modulates the pharmacokinetics, biodistribution, and therapeutic efficacy of the nanomedicines. While emerging evidence links obesity to heightened chemosensitivity, the underlying nanobio-interfacial mechanisms remain poorly understood. Herein, we demonstrate that pegylated liposomal doxorubicin (PLD) exhibits significantly enhanced antitumor and antimetastatic efficacy in obese breast tumor-bearing mice compared to normal controls. Mechanistic investigations reveal that obesity confers PLD with prolonged systemic circulation and improved tumor accumulation. Notably, preincubation of PLD with plasma from obese mice reduces macrophage uptake while promoting internalization by breast cancer cells compared to that from normal mice. Genetic ablation of apolipoprotein E (ApoE) in obese mice abolishes obesity-associated improvements in PLD blood circulation, tumor accumulation, and uptake by cancer cells. Conversely, supplementation with recombinant ApoE restores these effects in ApoE-deficient mice and potentiates PLD's antitumor efficacy. Collectively, our findings demonstrate obesity-induced ApoE as a pivotal regulator of the protein corona that actively enhances tumor-targeted delivery of PLD, which offers a rational strategy for engineering protein-corona-mediated tumor-targeted nanomedicines.

High-grade serous ovarian cancer (HGSC) is the most aggressive subtype of ovarian epithelial cancer (OEC), with characters of late-stage diagnosis, high recurrence rate, and poor survival outcomes. Fucosyltransferase 8 (FUT8) is responsible for α1,6-core fucosylation biosynthesis, and aberrant FUT8/α1,6-core fucosylation level is involved in tumor progression. However, the roles and mechanisms of protein FUT8 and α1,6-core fucosylation in HGSC tumorigenesis and progression remain elusive. Here, our study confirms that elevated levels of FUT8/α1,6-core fucose in the tissues and serum of HGSC patients, and the elevation is associated with poor patient prognosis. By applying glycoproteomic assay, we globally screen and identify NCEH1 as the specific scaffold protein of α1,6-core fucosylation. Alpha 1,6-core fucose modification stabilizes NCEH1 by preventing its degradation through proteasomal pathway. Importantly, combined with non-targeted metabolomics analysis, α1,6-core fucosylated NCEH1 facilitates LPA secretion, driving M2-like polarization of tumor-associated macrophages in the tumor microenvironment, thus leading to oncogenesis and peritoneal metastasis of HGSC in vitro and in vivo. These findings broaden the understanding of FUT8/α1,6-core fucosylation/NCEH1 in HGSC progression and metastasis, and offer glycosylated diagnostic indicators and targets for therapeutic strategies in HGSC.

To explore the association between apolipoprotein E (APOE) gene polymorphisms and the risk of premature (age of onset: men ≤ 55 years old, women ≤ 65 years old) myocardial infarction (PMI). This study retrospectively collected the medical records (age, gender, hypertension, diabetes mellitus, smoking, drinking, and serum lipid) of 379 PMI patients and 628 age-matched non-AMI individuals (controls), from December 2018 to March 2024. The relationship between APOE polymorphisms and PMI was analyzed. 15(1.5%) individuals carried ɛ2/ɛ2, 147(14.6%) had ɛ2/ɛ3, 16(1.6%) presented with ɛ2/ɛ4, 670(66.5%) were ɛ3/ɛ3 carriers, 149(14.8%) had ɛ3/ɛ4, and 10 (1.0%) carried ɛ4/ɛ4. The proportion of ɛ2/ɛ3 genotype was significantly lower in the PMI group than in controls (7.7% vs. 18.8%, p < 0.001), whereas the prevalence of ɛ3/ɛ4 genotype was substantially higher in the PMI group (20.6% vs. 11.3%, p < 0.001). Logistic regression analysis identified some associated factors: smoking (odds ratio [OR]: 3.057, 95% confidence interval [CI]: 2.098-4.455, p < 0.001), hypertension (OR: 4.474, 95% CI: 3.273-6.117, p < 0.001), and dyslipidemia (OR: 1.805, 95% CI: 1.333-2.443, p < 0.001). Additionally, genetic factors were associated with PMI: the APOE ɛ3/ɛ4 genotype (vs. ɛ3/ɛ3, OR: 1.548, 95% CI: 1.038-2.309, p = 0.032) and the presence of ɛ4 allele (vs. ɛ3, OR: 1.521, 95% CI: 1.033-2.241, p = 0.034) were confirmed as independent associated factors. APOE ε3/ε4 genotype was significantly associated with PMI, suggesting that this genotype could serve as a potential genetic marker for PMI risk assessment. Show less

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

To retrospectively analyze the effects of Butylphthalide and Sodium Chloride Injection (BP-SC) combined with Argatroban (AG) on neurological deficits and hemorheology in progressive ischemic stroke (PIS) patients. A total of 123 PIS patients admitted to our hospital between April 2023 and April 2025 were retrospectively analyzed and divided into two groups according to the different treatment schemes: the control group (n=58; treated with AG) and the research group (n=65; treated with BP-SC and AG). Clinical efficacy, neurological deficits (assessed by the National Institutes of Health Stroke Scale [NIHSS]), neurological function (astrocyte-derived protein S100β, brain-derived neurotrophic factor [BDNF], and neuron-specific enolase [NSE]), hemorheology (fibrinogen [FIB], plasma viscosity [PV], whole blood low-shear viscosity [WBLSV]), vascular endothelial function (endothelin-1 [ET-1] and nitric oxide [NO]), inflammatory factors (high-sensitivity C-reactive protein [hs-CRP], interleukin-6 [IL-6], and tumor necrosis factor-α [TNF-α]), adverse events (gingival bleeding, subcutaneous ecchymosis, nausea, abdominal distension, and vomiting), the 90-day post-operative modified Rankin Scale (mRS) score were compared between the two groups. Compared with the control group, the research group demonstrated significantly higher overall effective rate and favorable prognosis rate. The research group also showed greater post-treatment reductions in the NIHSS score and levels of S100-β and NSE, along with a more pronounced elevation in BDNF level, indicating improved neuronal function. Additionally, the combined treatment significantly improved multiple hemorheological indices and endothelial function as evidenced by reduced ET-1 level and elevated NO level. Moreover, levels of hs-CRP, IL-6, and TNF-α were significantly decreased. However, the total incidence of adverse events was comparable between the two groups. Combined treatment with BP-SC and AG exerts more significant improvements in neurological deficits and hemorheological parameters in PIS patients. Show less

Atherosclerosis is a major cause of cardiovascular diseases, and endothelial cells (ECs) senescence plays a key role in its initiation and progression. This study investigates the function and epigenetic regulatory mechanisms of long non-coding RNA (lncRNA) OIP5 antisense RNA 1 (OIP5-AS1) in oxidized low-density lipoprotein (Ox-LDL)-induced senescence and atherosclerosis in human aortic endothelial cells (HAECs). The experiments show that Ox-LDL stimulation upregulates the expression of OIP5-AS1 and RASA1 while inhibiting miR-30b-5p. Silencing OIP5-AS1 significantly suppresses the expression of senescence-associated secretory phenotype (SASP) factors, alleviates HAECs senescence, and enhances proliferation, migration, and angiogenesis. Methylation-specific primers (MSP) and bisulfite-specific primers (BSP) analyses reveal that Ox-LDL stimulation activates OIP5-AS1 expression by reducing the DNA methylation level in its promoter region and altering histone modifications (increased H3K27ac and decreased H3K9me3). Luciferase assays show that OIP5-AS1 acts as a competing endogenous RNA (ceRNA) by binding to miR-30b-5p and upregulating RASA1. Animal experiments further confirm that the knockdown of OIP5-AS1 alleviates atherosclerosis in ApoE Show less

The quality of informal care for people with dementia (PwD) has gained increasing importance, as most PwD prefer home-based care over institutional placement. However, evidence-based intervention programs tailored to distinct care quality profiles remain limited. Additionally, the absence of clear thresholds to identify PwD receiving low-quality informal care poses a challenge for research and clinical practice. Thus, this study aimed to identify the profiles of quality of care (QoC) among informal caregivers of PwD, explore influencing factors of different profile, and determine the optimal cut-off score of the Exemplary Care Scale (ECS). A cross-sectional survey was conducted. A total of 213 dyads of PwD and their informal caregivers were recruited from memory clinic, rehabilitation clinic, and neurological clinic of a tertiary hospitals and communities in Wuhan, Hubei, China, between July 15, 2023, and July 14, 2024. Latent profile analysis (LPA) was employed to identify QoC profiles. Multinomial logistic regression was performed to explore influencing factors of profile membership. Receiver Operating Characteristic (ROC) analysis was conducted to determine the ECS cut-off score. Three distinct QoC profiles were identified: high (24.41%), moderate (44.60%), and low (30.99%). Among informal caregivers, lower monthly income, insufficient social support, and higher perceived overload were associated with low QoC profile, whereas, better quality of pre-illness relationship with PwD and greater activities of daily living (ADL) of PwD were associated with high QoC. ROC analysis yielded an optimal ECS cut‑off score of 15, with high sensitivity (0.993) and specificity (0.955). This study identified three distinct QoC profiles among caregivers of PwD, underscoring the heterogeneity of informal care quality. The identified predictors and the validated ECS cut‑off score of 15 provide an empirical basis for developing tailored screening tools and targeted interventions for high‑risk caregiver subgroups.

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

Prednisone is used clinically during pregnancy. This study investigates whether prenatal prednisone exposure (PPE) affects susceptibility to high-fat diet (HFD)-induced metabolic dysfunction-associated fatty liver disease (MAFLD) in adult offspring and explores underlying mechanisms. Pregnant Kunming mice were administered prednisone (0.25 or 1 mg/kg; PPE-L or PPE-H) or vehicle control (5% carboxymethyl cellulose; Ctrl) by daily gavage from gestational days 0-18. Offspring were assessed metabolically, histologically, and via RNA-Seq. Primary hepatocytes were treated with fatty acids with or without the epigenetic inhibitors to evaluate Nr1h3 expression and lipid deposition. Offspring body weight was similar in PPE-L vs Ctrl, but was reduced in PPE-H group followed by delayed growth. After 6-week HFD feeding, PPE-L offspring showed mild metabolic issues, while PPE-H males exhibited significant glucose/lipid disorders and hepatic steatosis compared to controls. RNA-Seq showed upregulation of hepatic lipid pathways in the PPE-H male offspring when challenged by HFD. The liver X receptor alpha (LXRα)-sterol regulatory element-binding protein 1 (SREBP1) signaling pathway and the expression of genes involved in de novo fatty acid synthesis were increased in PPE-H offspring under HFD. A485 significantly downregulated the expression of Nr1h3 in primary hepatocytes from male PPE-H offspring and alleviated lipid deposition in these hepatocytes treated with fatty acids. The H3K27ac level in the Nr1h3 promoter in the PPE-H offspring's liver was significantly upregulated. PPE-L impairs offspring glucose/lipid homeostasis, whereas PPE-H increase MAFLD risk of the offspring by epigenetic programming of the hepatic LXRα-SREBP1 pathway, especially in the males. Show less

This study aims to systematically investigate the multi-target mechanisms of cobalamin in the treatment of ischemic stroke using network pharmacology and molecular docking approaches. We screened databases to identify the targets of cobalamin and performed intersected with with ischemic stroke-related targets to construct a “drug-target-disease” interaction network. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses were conducted to identify key biological processes and signaling pathways. Additionally, molecular docking simulations were performed to assess the binding affinity between cobalamin and hub proteins. Molecular dynamics (MD) simulations were used to assess the stability of the protein–ligand complexes over a 500 ns simulation period. Additionally, ADME (Absorption, Distribution, Metabolism, Excretion) and blood–brain barrier (BBB) permeability predictions were made using ADMETlab 3.0 and admetSAR 3.0. A total of 95 therapeutic targets of cobalamin for ischemic stroke were identified. Network analysis and molecular docking highlighted eight core targets—ALB, TIMP1, PLG, FN1, AGT, SERPINE1, APOE, and SPP1—with high binding affinities to cobalamin. GO analysis suggested that cobalamin regulates inflammatory responses, post-translational modifications, complement binding, and lipoprotein particle binding. KEGG analysis identified complement and coagulation cascades, the PI3K/AKT pathway, and inflammation-related signaling as central to its therapeutic effects. Molecular docking showed strong binding to ALB and TIMP1, which was further confirmed by MD simulations, with minimal conformational changes. The PLG-cobalamin complex exhibited more fluctuations. ADME analysis revealed low passive permeability, particularly across the blood–brain barrier, but moderate distribution and high plasma protein binding. This study provides evidence that cobalamin may offer neuroprotective effects in ischemic stroke by interacting with key target proteins involved in coagulation, inflammation, and lipid metabolism. The findings highlight the potential of cobalamin as a therapeutic agent, although its limited ability to cross the blood–brain barrier may restrict its oral use. Further experimental validation and development of suitable delivery methods are needed to fully realize cobalamin’s potential in stroke therapy.

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

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

Using GWAS statistics for 9 OA subtypes and 51 MTs, we identified both global and regional genetic correlations. Multi-trait GWAS helped revealed credible genes and relevant pathways through various methods. Protein-level analyses were also conducted to identify key proteins. We developed polygenic scores (PGS), machine learning models and drug repurposing strategies were explored to translate these findings into clinical applications. We identified 152 trait pairs with significant associations and 709 local regions linked to OA-MT. Key SNVs like rs13135092 (SLC39A8) and rs34811474 (ANAPC4) were associated with multiple OA-MT pairs. Lipid and glucose metabolism emerged as central pathways, with tissue-specific enrichment analyses revealing key gene clusters in hepatocytes, arteries, and brain regions. Protein-level analyses identified 205 protein subgroups. PGS integrating MTs outperformed model based solely on OA, improving AUC by 17.5%. Causal gene-based models showed strong diagnostic accuracy (average AUC = 0.875 in external cohorts). Drug prediction highlighted fenofibrate as a promising treatment among 71 candidates. This study provides new insights into the genetic links between OA and MTs. We identified genes, proteins, and pathways related to comorbidities, revealing shared mechanisms, highlighting the potential of integrating metabolic factors to improve OA prediction, diagnosis, and treatment.

Older adults increasingly rely on digital health resources, yet evidence regarding the relationship between eHealth literacy (eHL) and 24-hour movement behaviors (24-HMB), including physical activity (PA), sedentary behavior (SB), and sleep, remains underexplored. This study examined the associations between eHL and 24-HMB in Chinese older adults and examined self-efficacy as a potential mediator and moderator. Using a convenience sampling approach, 564 community-dwelling older adults (aged 60-74 years) were recruited from four urban Chinese cities via an online survey. A total of 553 valid cases were retained for analyses. eHL was assessed using the eHealth Literacy Scale-Web 3.0, and self-efficacy was assessed using a validated Self-Efficacy Scale. PA and SB were assessed objectively using ActiGraph GT3X+ accelerometers over three consecutive days (two weekdays and one weekend day). Sleep duration was derived from accelerometer-based estimates anchored by daily sleep logs. Multiple linear regression analyses were conducted to examine associations, and mediation and moderation were tested using PROCESS macro (Model 4 and Model 1, respectively), adjusting for age, sex, and education. After adjustment for covariates ( In this cross-sectional, urban, device-using sample of older adults, higher eHL was associated with a more favorable 24-HMB profile, particularly higher LPA and lower SB, while associations with sleep duration were weaker. Self-efficacy showed modest indirect associations consistent with partial mediation for PA and SB and also acted as a moderator of several associations. Given the observational design and modest effect sizes, findings should be interpreted cautiously and require confirmation in longitudinal or experimental studies with more representative sampling and improved sleep assessment.

Pulmonary fibrosis is a common and life-threatening complication of Parkinson's disease (PD), yet the molecular mechanisms linking the two diseases remain unclear, creating a critical gap in targeted therapeutic strategies for comorbid patients. Angiotensin-converting enzyme 2 (ACE2) plays a key role in neuroprotection and lung homeostasis; its deficiency exacerbates PD-related neuroinflammation and α-synuclein aggregation, while also promoting pulmonary inflammation and fibrotic remodeling. Clarifying how ACE2 deficiency drives PD-exacerbated pulmonary fibrosis is therefore an urgent unmet need. This study explored the underlying mechanisms using MPTP-induced PD mouse models and bioinformatics analyses of PD/idiopathic pulmonary fibrosis (IPF) datasets from the GEO database. In MPTP-induced PD mice, ACE2 deficiency significantly worsened motor/non-motor dysfunction, dopaminergic neuron loss, microglial/astrocytic activation, and lung fibrosis (evidenced by elevated α-SMA/TGF-β and increased collagen deposition). Bioinformatics identified 41 overlapping differentially expressed genes (DEGs) between PD and IPF, enriched in critical pathways: downregulated FoxO1 (impairing antioxidant defense) and upregulated TNF, JAK1-STAT3, and AGE-RAGE (amplifying inflammation/fibrosis). ROC analysis validated hub genes (e.g., BDNF, FOSL2) with good diagnostic value (AUC > 0.7), and molecular docking identified Smilagenin, Fostamatinib, Olopatadine, and Amlexanox as potential therapeutics. This study confirms ACE2 deficiency is a central driver of PD-exacerbated pulmonary fibrosis via the FoxO1/TNF/JAK1-STAT3/AGE-RAGE pathways, providing novel biomarkers and drug candidates to address the clinical need for managing this comorbidity.

Chronic pain (CP) and major depressive disorder (MDD) are highly disabling global diseases, and their high comorbidity creates a bidirectional vicious cycle, significantly exacerbating functional impairment and treatment resistance. Multidisciplinary evidence suggests that the comorbid nature arises from deep functional coupling and neural network remodeling between the sensory-pain and emotional systems, rather than merely a symptom overlap. Neuroimaging, animal models, and neuromodulation studies demonstrate that key brain regions, including the prefrontal cortex (PFC), anterior cingulate cortex (ACC), amygdala, hippocampus, insula, and reward system, show consistent abnormalities in the comorbid state, creating a cross-brain network that jointly regulates pain, emotion, and cognition. This paper systematically reviews the central structures, neural circuits, and neurotransmitter regulatory mechanisms of CP-MDD comorbidity and proposes an integrated emotion-perception coupling network model. We highlight the mechanisms and translational potential of multi-pathway intervention strategies, with a focus on neuromodulation techniques (rTMS, tDCS), combined with ketamine, BDNF modulators, and anti-inflammatory drugs. Additionally, it is emphasized that future research must integrate multimodal imaging, multi-omics data, and computational modeling to establish a mechanism-driven personalized stratification system. With the support of high spatiotemporal resolution brain connectomics technology, this will facilitate the transition from a 'symptom control' to a 'mechanism repair' paradigm in treating comorbidities.

Neuropathic pain (NP), a chronic disorder caused by somatosensory nervous system lesions, severely impairs the quality of life. Microglial metabolic reprogramming and neuroinflammation drive NP progression. Although ChREBP (key metabolic regulator) protects against NP, its specific mechanisms remain unclear. NP rat model was established via spared nerve injury (SNI) surgery, and mechanical allodynia was evaluated using Von Frey tests. ChREBP expression in microglia was detected through immunofluorescence, RT-qPCR, and western blot. Functional studies involved ChREBP knockdown/overexpression to assess effects on microglial polarization, neuroinflammation, neuronal excitability, pain behaviors, and fatty acid metabolism. Mechanisms were explored via dual-luciferase reporter and chromatin immunoprecipitation assays. Mechanical pain thresholds were significantly decreased on the ipsilateral side after SNI. ChREBP was upregulated in SDH microglia after SNI and in LPS-stimulated microglia in vitro. ChREBP knockdown inhibited anti-inflammatory microglial polarization, exacerbated neuroinflammation, and aggravated pain. Conversely, ChREBP overexpression promoted the anti-inflammatory phenotype, suppressed neuroinflammation, and alleviated pain. ChREBP enhanced microglial fatty acid oxidation and energy metabolism. Mechanistically, ChREBP bound to the TFBS1 site on the PGC-1α promoter to activate its transcription. PGC-1α overexpression rescued the impairments caused by ChREBP knockdown, including reduced fatty acid oxidation, suppressed anti-inflammatory polarization, elevated inflammatory factors, and increased neuronal excitability. The protective effects of ChREBP were attenuated by the fatty acid oxidation inhibitor Etomoxir. ChREBP alleviates NP by enhancing microglial fatty acid oxidation and anti-inflammatory phenotype via PGC-1α transcriptional activation, revealing a novel metabolic-immune axis for potential NP therapy.

Focal articular cartilage defects often progress to osteoarthritis, imposing a substantial global health burden. Current neglect of cartilage developmental regulation and cartilage microenvironment compromises therapeutic efficacy. We developed an innovation CE-SKP/CPH/P2G3 scaffold which effectively repairs focal cartilage defects and emulates native cartilage ontogeny: the superficial CE-SKP hydrogel layer recruits SMSCs and promotes chondrogenesis; the middle CPH hydrogel layer induces chondrocyte hypertrophic calcification, forming cartilage calcified layer; and the basal P2G3 nanofiber membrane isolates subchondral cells, enforcing a top-down developmental sequence and preserving a localized hypoxic niche.

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