Cognitive impairment is a significant health concern in aging populations, but the interplay between biological aging, lifestyle factors, and genetic susceptibility remains unclear. This study examined whether accelerated biological aging is associated with cognitive impairment, whether lifestyle modifies this association, and how genetic background influences these relationships in Chinese older adults. In this cross-sectional study (2022-2023), 7033 participants from southwestern China were included. Accelerated biological aging was calculated as the residual difference between biological age (based on 10 biomarkers) and chronological age. Lifestyle was assessed via a composite index (smoking, alcohol, physical activity, diet, sleep). Cognitive function was measured using the Chinese Mini-Mental State Examination (C-MMSE), and genetic risk was evaluated through polygenic scores and APOE ε4 status. Linear and logistic regression models assessed associations between accelerated aging and cognition. Accelerated biological aging was associated with lower MMSE scores ( β = -0.243, 95% CI: -0.354, -0.133) and higher cognitive impairment prevalence (OR = 1.098, 95% CI: 1.040, 1.158). An unhealthy lifestyle exacerbated cognitive impairment in biologically older individuals (RERI = 0.25). Those with both accelerated aging and unhealthy lifestyle had the lowest MMSE scores ( β = -1.424, 95% CI: -1.846, -1.003) and highest odds of cognitive impairment (OR = 1.467, 95% CI: 1.194, 1.803). These effects were consistent across all genetic background subgroups. Accelerated aging was associated with lower cognitive function, especially in individuals with unhealthy lifestyles, regardless of genetic susceptibility. This highlights lifestyle modification as a potential intervention target for aging-related cognitive impairment. Show less

Aging and age-related diseases share convergent pathways at the proteome level. Here, using plasma proteomics and machine learning, we developed organismal and ten organ-specific aging clocks in the UK Biobank (n = 43,616) and validated their high accuracy in cohorts from China (n = 3,977) and the USA (n = 800; cross-cohort r = 0.98 and 0.93). Accelerated organ aging predicted disease onset, progression and mortality beyond clinical and genetic risk factors, with brain aging being most strongly linked to mortality. Organ aging reflected both genetic and environmental determinants: brain aging was associated with lifestyle, the GABBR1 and ECM1 genes, and brain structure. Distinct organ-specific pathogenic pathways were identified, with the brain and artery clocks linking synaptic loss, vascular dysfunction and glial activation to cognitive decline and dementia. The brain aging clock further stratified Alzheimer's disease risk across APOE haplotypes, and a super-youthful brain appears to confer resilience to APOE4. Together, proteomic organ aging clocks provide a biologically interpretable framework for tracking aging and disease risk across diverse populations. Show less

Defective Wnt/β-catenin signaling is closely associated with the pathogenesis of Alzheimer's disease (AD), thus validating this pathway as a therapeutic target for AD. ISX9 is a potent agonist of the Wnt/β-catenin pathway. However, it remains unknown whether ISX9 exerts anti-AD effects by enhancing the Wnt/β-catenin signaling pathway. We therefore explored the neuroprotective potential of ISX9 using both hippocampal neuron-derived HT22 cells and 5×FAD transgenic mouse model of AD. In HT22 cells, we employed the SuperTOPFlash reporter gene, Co-IP and Western blot assays to investigate the mechanism by which ISX9 activates the Wnt signaling pathway. The effects of ISX9 on the biological behavior of HT22 cells were further evaluated through MTT, BrdU and IF staining. To study the therapeutic effect of ISX9 on AD, six-month-old 5×FAD transgenic mice were randomly divided into four groups: WT, WT/ISX9, AD and AD/ISX9. The mice were intraperitoneally injected with ISX9 or vehicle at an interval of one day for 2 months. Behavioral tests were conducted to evaluate the cognitive and learning abilities of mice, while the expression levels of Aβ peptides, Tau-related proteins, neuroinflammatory factors, blood-brain barrier (BBB)-related proteins and the components of Wnt/β-catenin signaling were investigated. Our results demonstrated that ISX9 potently activated Wnt/β-catenin signaling by promoting the association of LRP6 with AXIN1, and increased the viability and proliferation of hippocampal cells. At the behavioral level, ISX9 improved learning and memory abilities in 5×FAD mice, and ameliorated hippocampal neuronal damage. Furthermore, ISX9 treatment effectively reduced the expression of Aβ peptides, total Tau, and phosphorylated Tau (S404) proteins in the AD mice. Mechanistically, ISX9 exhibited its neuroprotective effects, activating the Wnt/β-catenin signaling pathway via potentiating the interaction of LRP6 with AXIN1, upregulating the expression of BBB-related proteins and downregulating neuroinflammatory factors in AD mice. Our findings indicate that ISX9 potently activates the Wnt/β-catenin signaling pathway and confers cognitive protection in hippocampal cells and AD mice. This compound may serve as a promising therapeutic agent for the treatment of AD. Show less

Alzheimer's disease (AD) represents the most prevalent form of neurodegenerative disorder, characterized by progressive cognitive impairments and a scarcity of effective treatments. Salvianolic acid A (SalA), a natural phytochemical endowed with antioxidative, antiapoptotic, and anti-inflammatory properties, emerges as a promising therapeutic candidate for AD. This study explored the therapeutic efficacy and underlying mechanisms of SalA in mitigating AD-related pathologies. Through integrative network pharmacology, molecular docking, and pathway enrichment analysis, p38 MAPK and NF-κB were identified as potential targets of SalA in the context of AD. SalA treatment inhibited the activation of the p38 MAPK/NF-κB pathway via targeting p38 MAPK, leading to decreased levels of IL-1α and IL-1β in lipopolysaccharide (LPS)-stimulated HMC3 cells. In an in vivo 3 × Tg-AD mouse model, SalA administration ameliorated cognitive decline associated with AD, decreased tau protein hyperphosphorylation in the hippocampus and cortex, and reduced amyloid-β (Aβ) accumulation and β-site amyloid precursor protein cleaving enzyme 1 (BACE1) levels. Furthermore, SalA attenuated the activation of the p38 MAPK/NF-κB pathway and the expression of related inflammatory cytokines in the brains of 3 × Tg-AD mice. In conclusion, this study elucidates the promising ameliorative effects of SalA on improving AD pathology, primarily through the modulation of the p38 MAPK/NF-κB signaling pathway. Show less

Apoptosis plays a significant role in osteoporosis (OP), yet a causal relationship between apoptosis gene expressions and OP remains unexplored. This study applies an integrated multi-omics analysis to establish causality between them, offering clinical treatment and prediction insights. Apoptosis-related genes are sourced from GeneCards, and 6 transcriptomic datasets from the cells in the circulation are obtained from GEO. Meta-analysis integrated differentially expressed apoptosis-related genes (DEGs) from the above 6 datasets. Causality between gene expressions, epigenetic changes, and OP is examined using OP genome-wide association study (GWAS), plasma expression quantitative trait loci (eQTL), and methylation quantitative trait loci (mQTL) data, while analysis of skeletal muscle eQTL and OP GWAS data is conducted. External validation is performed with the UK Biobank datasets. Meta-analysis of 6 GEO datasets identified 384 DEGs, including 78 apoptosis-related genes. The three-step analysis indicates 8 candidate causal genes in blood, including MAP3K3, DPP8, RPL3, PPP2CA, CD86, LRRFIP1, TRAP1, and DUSP6, with LRRFIP1 influenced by four methylation sites. Analysis of skeletal muscle data reveals 4 causal genes, including SIPA1L3, PDLIM7, CTNNB1, and DPP8. Among apoptosis-related genes causally linked to OP in both circulation and skeletal muscle, LRRFIP1 was validated based on methylation-associated regulation and demonstrated consistent, reproducible expression patterns. This study uses a multi-omics strategy to clarify the roles of apoptosis-related gene expressions and their corresponding methylation in OP, providing targets and a basis for early diagnosis, personalized treatment, and monitoring of OP.

This study aims to investigate the role of DUSP6 in thyroid cancer metastasis and elucidate its underlying molecular mechanisms. Immunohistochemistry were performed to explore the expression of DUSP6, IL-8 and PAD4 in papillary thyroid carcinoma (PTC) tissues and adjacent non-cancerous thyroid tissues. Effects of DUSP6 on the proliferation, apoptosis, migration, and invasion of thyroid cancer cell lines TPC-1 and IHH4 were performed through in vitro experiments. A rescue experiment was performed to verified DUSP6 regulated the migration and invasion of thyroid cancer cells TPC-1 and IHH4 through IL-8 and neutrophil extracellular traps (NETs) formation. In addition, in vitro cell experiments were conducted to analyze the regulation of NETs formation by DUSP6 through IL-8. Finally, the effect of sh-DUSP6 on the growth of thyroid cancer tumors in mice were conducted through in vivo experiments. DUSP6 expression was significantly upregulated in PTC tissues. Moreover, the expression of DUSP6 in tumor tissues of TPC patients is positively correlated with the expression of IL-8 and PAD4. Overexpression of DUSP6 promotes the proliferation, migration, and invasion of thyroid cancer cells (TPC-1 and IHH4) while inhibiting apoptosis. Conversely, silencing DUSP6 exerts opposing effects. Knockdown of IL-8 reverses the enhanced migratory and invasive capabilities induced by DUSP6 overexpression in these cell lines. NETs treatment enhances the migration and invasion of TPC-1 and IHH4 cells, whereas the application of sh-DUSP6 or sh-IL-8 counteracts this NETs-mediated promotion. Furthermore, DUSP6 overexpression facilitates NETs formation by upregulating IL-8 expression. In vivo experiments demonstrate that sh-DUSP6 suppresses thyroid cancer tumor growth in mouse models. Conclusion: DUSP6 promotes the metastasis of thyroid cancer by facilitating the formation of neutrophil extracellular traps via IL-8. Show less

Sickle cell disease (SCD) is characterized by osteopenia and impaired bone mineralization, but the underlying mechanisms remain unclear. Fibroblast growth factor 23 (FGF23), elevated in SCD, regulates phosphate metabolism through FGFRs/klotho and contributes to bone loss. Although FGF23's systemic effects are known, its local actions in SCD bone remain poorly defined. Using bone marrow stromal cells (BMSCs) derived from SCD mice, we previously reported that enhanced local FGF23/FGFR1 signaling and increased osteopontin impair osteoblast mineralization, which is rescued by an FGF23-neutralizing antibody (FGF23Ab). Here, we further investigated downstream signaling and pyrophosphate/phosphate (PPi/Pi)-regulatory mechanisms contributing to mineralization defects. FGF23Ab reduced phospho-FGFR1, restored phospho-FGFR2 and phospho-AKT, and decreased pSTAT3 activation. SCD-BMSCs exhibited increased matrix inhibitors, matrix Gla protein (MGP) and matrix extracellular phosphoglycoprotein (MEPE), and reduced mineralization promoters PHEX and DMP1, which were partially normalized by FGF23Ab. FGF23Ab also corrected elevated PPi-generating enzymes ENPP1 and ANK and restored tissue-nonspecific alkaline phosphatase (TNAP). In contrast, the phosphate importer PiT2 was significantly reduced in SCD BMSCs and was further suppressed with FGF23Ab. These findings indicate that excessive local FGF23 signaling disrupts mineralization by upregulating matrix inhibitors and altering PPi/Pi-regulatory pathways. FGF23 neutralization partially restores mineralization capacity. Show less

Hypertrophic scar (HS) is a fibroproliferative disorder characterized by fibroblast hyperactivation and aberrant extracellular matrix deposition. This study identifies macrophage-derived lactate as a key mediator of fibroblast phenotypic remodeling via monocarboxylate transporter 1 (MCT1)-mediated histone H3 lysine 23 lactylation (H3K23la) in HS. Elevated lactate levels and MCT1 expression were observed in HS tissues, with macrophages in stiff mechanical microenvironments identified as the primary lactate source. Lactate influx through MCT1 upregulated H3K23la, thereby promoting transcriptional activation of profibrotic genes HEY2 and COL11A1. Mechanistically, HEY2 activated YAP1/SMAD2 signaling, while COL11A1 stabilized MCT1 to enhance lactate transport, forming a positive loop that amplified fibrosis. Fibroblast-specific Mct1 deletion or pharmacological inhibition of Mct1 in male mice reduced collagen deposition, accelerated wound healing, and attenuated scar formation. Our findings redefine the macrophage-fibroblast crosstalk in HS and establish the MCT1-H3K23la-HEY2/COL11A1 axis, particularly its self-reinforcing loop, as a novel therapeutic target. Show less

Previous research on breast cancer patients has primarily examined singular behavioral indicators, often overlooking the coexistence and interaction between physical activity and sedentary behavior-particularly screen-based sedentary time. This study aims to identify the latent activity pattern categories among breast cancer patients during chemotherapy intervals and explore their associated factors to inform targeted behavioral interventions. A cross-sectional survey was conducted with 292 breast cancer patients undergoing chemotherapy intervals at four general hospitals in Foshan, Guangdong Province. Latent Profile Analysis (LPA) was applied as a person-centered analytic approach to identify distinct activity pattern profiles. Data were collected using a general information questionnaire, the Adult Sedentary Behavior Questionnaire (ASBQ), the Chinese version of the International Physical Activity Questionnaire (IPAQ-SC), the Exercise Self-Efficacy Scale (ESES), the Perceived Social Support Scale (PSSS), and the Hospital Anxiety and Depression Scale (HADS). The activity patterns of breast cancer patients were categorized into three groups: Moderate Activity-Dominant Group (37.33%), Screen-Sedentary High-Risk Group (8.22%), and Activity-Sedentary Coexistence Group (54.45%). Logistic regression analysis showed that, compared to the Moderate Activity-Dominant Group, patients with low exercise self-efficacy and higher anxiety and depression levels were more likely to be classified into the Screen-Sedentary High-Risk Group and Activity-Sedentary Coexistence Group. Higher education levels and being on medical leave were associated with a higher probability of belonging to the Activity-Sedentary Coexistence Group (all Activity patterns in breast cancer patients show significant heterogeneity. Healthcare providers should pay attention to the individual physical activity characteristics of patients and offer personalized physical activity guidance. Tailored interventions that meet the needs of breast cancer patients should be developed to improve health outcomes. Show less

Nursing interns often face maladjustment during the early stages of clinical practice, which not only directly affects their physical and mental health as well as work efficiency but also significantly inhibits their proactive feedback-seeking behavior (FSB). As an active self-regulation strategy, FSB can enhance interns' work initiative and promote role transition. However, existing research has yet to thoroughly investigate the potential heterogeneity and categorical characteristics of FSB within this population, and the role of psychological resources such as career adaptability in shaping these patterns requires further investigation. To investigate the status of FSB in early-stage nursing interns, identify latent subgroups via latent profile analysis (LPA), and analyze associated factors, thereby providing evidence for targeted clinical educational interventions. Multicenter cross-sectional research. This study employed a multistage stratified cluster sampling to survey 1,308 early-stage nursing interns from nine universities in Hubei, China, between June and September 2024. Data were collected using a demographic questionnaire, Feedback-Seeking Behavior Scale, and Career Adapt-Abilities Scale. LPA was employed to delineate FSB profiles and multivariate logistic regression analysis to examine the associated predictors. A total of 1,370 questionnaires were distributed, with 1,308 valid responses, yielding an effective response rate of 95.47%. The mean score on the feedback-seeking behavior scale was 5.06 ± 1.08. LPA identified three distinct feedback-seeking profiles: low (20.87%), moderate (38.3%), and high (40.83%). Education level, student cadre experience, internship hospital type, and career adaptability were significant predictors of profile membership ( FSB among early-stage nursing interns exhibited heterogeneity. Nursing educators and managers should implement tiered interventions: for the low and moderate feedback-seeking groups, career guidance and feedback awareness cultivation should be strengthened; for the high feedback-seeking group, peer modeling should be encouraged. This strategy can enhance proactive FSB, supports role transition and professional identity, and promotes long-term nursing workforce stability. Show less

Problematic mobile phone use (PMPU) has become a prominent public health concern among Chinese adolescents and emerging adults, yet prior research has largely relied on variable-centered approaches that overlook within-group heterogeneity and provide limited insight into multilevel mechanisms. To address these gaps, this study adopted an integrated analytic framework combining latent profile analysis (LPA), structural equation modeling (SEM), and psychological network analysis. A total of 2345 Chinese university students completed measures of alexithymia (TAS-20), social interaction anxiety (IAS), and PMPU (MPAI). LPA identified three distinct PMPU profiles: Low-risk (62.7%), moderate-risk (24.8%), and high-risk (12.5%). SEM results indicated that alexithymia was positively associated with PMPU in the overall sample, with social interaction anxiety partially mediating this association. Profile-specific analyses further showed that the indirect pathway was significant in the low-risk and moderate-risk profiles but not in the high-risk profile, in which only a direct effect emerged. Network analyses in the low- and moderate-risk groups revealed profile-specific central and bridge nodes, primarily IAS items, highlighting potential symptom targets linking alexithymia and PMPU. Overall, findings underscore meaningful heterogeneity in PMPU and support profile-tailored prevention and intervention strategies emphasizing emotion-processing skills and social anxiety reduction.

Coronary artery calcification (CAC) signifies advanced atherosclerosis and portends increased cardiovascular risk. Lipoprotein(a) [Lp(a)] is a causal risk factor for atherosclerosis; however, its association with in vivo lesion morphology and clinical outcomes in patients with symptomatic, advanced CAC remains incompletely characterized. This study aimed to investigate the association between elevated Lp(a) levels and both in vivo lesion morphology and clinical outcomes in this high-risk population. In this retrospective cohort, 292 patients with intravascular ultrasound(IVUS)-confirmed CAC were stratified into elevated (≥50 mg/dL,n = 77) or low (<50 mg/dL,n = 215) Lp(a) groups. The primary endpoint was major adverse cardiovascular events (MACEs). Associations were assessed via multivariable Cox models adjusted for clinical covariates. Patients in the elevated Lp(a) group presented a greater incidence of aortic valve calcification (p < 0.001). IVUS revealed constrictive remodeling with a smaller lumen and vessel dimensions. During a median follow-up of 17.2 months, the elevated Lp(a) cohort had a significantly higher MACE rate (37.7% vs. 15.8%; adjusted hazard ratio [aHR] 2.60, 95% CI 1.55-4.35, p < 0.001). Elevated Lp(a) independently predicted increased risks of ischemic stroke (aHR 7.14) and in-stent restenosis (aHR 2.78). In symptomatic patients with IVUS-confirmed CAC, elevated Lp(a) identifies a high-risk phenotype characterized by constrictive vascular remodeling and a markedly increased risk of MACEs, driven particularly by ischemic stroke and in-stent restenosis. These findings support the integration of routine Lp(a) testing into the risk stratification of patients with severe CAC, thereby identifying a precise high-risk phenotype that warrants intensified monitoring and represents an ideal target for emerging Lp(a)-lowering therapies.

Physical activity (PA) is known to enhance brain health; however, prior research has predominantly concentrated on the total volume of PA, often overlooking the frequency of daily PA on an hourly basis. This prospective cohort study examined 69,393 middle-aged and older adults, utilizing wrist-worn accelerometer data to assess PA. A novel PA frequency score was developed, which integrated light PA (LPA) and moderate-to-vigorous PA (MVPA) across 18 hourly segments (6:00 AM-12:00 AM). Participants were categorized into Inactive, Active, and Very Active groups. After adjusting for potential confounders, it was observed that individuals in the Active and Very Active groups exhibited a reduced risk of developing brain disorders such as dementia, anxiety, depression, migraine, Parkinson's disease, and stroke over a median follow-up period of 7.41 years. Magnetic Resonance Imaging (MRI) findings demonstrated that each unit increase in the PA frequency score correlated with a 51.55 mm Show less

This study aimed to identify latent classes of adherence for serum phosphorus control and their influencing factors among patients receiving Peritoneal Dialysis with hyperphosphatemia. This cross-sectional study using convenience sampling was conducted among patients receiving peritoneal dialysis with hyperphosphatemia between December 2024 and May 2025. Participants were assessed using the Phosphate Control Adherence Scale, Self-Efficacy Scale, and Family Care and Social Support Scale. Demographic and clinical data were also collected. Latent profile analysis (LPA) was used to identify adherence subgroups. Univariate analysis and multicollinearity diagnostics were performed, followed by binary logistic regression to determine predictors of adherence. Blood phosphorus control adherence can be classified into two categories: the low-level medical adherence group, characterized by poor dietary self-control (19.93%), and the high-level medical adherence group, marked by effective medication adherence (80.07%). The results indicated that residence conditions, types of medication, and self-efficacy significantly influenced blood phosphorus control adherence among patients with various forms of PD hyperphosphatemia (all p < 0.05). Patients with hyperphosphatemia undergoing peritoneal dialysis exhibit heterogeneity in adherence to serum phosphorus control. This indicates that healthcare providers should identify the adherence characteristics of different patient groups at an early stage and implement targeted intervention strategies to enhance patients' adherence to serum phosphorus management.

This study aims to identify the latent profiles of sense of coherence (SOC) in patients with advanced cancer and explore its influencing factors encompassing sociodemographic and clinical characteristics, and generalized resistance resources (GRRs). A cross-sectional study of 262 patients with advanced cancer was conducted by convenience sampling in Guangzhou, China, from September 2023 to July 2024. Data were collected including sociodemographic and clinical characteristics, SOC-13, Revised Life Orientation Test (LOT-R), Rosenberg Self-Esteem Scale (RSES), Inner Peace State Scale (IPSS), Gratitude Questionnaire-6 (GQ-6), and Social Support Rating Scale (SSRS). Statistical analysis was performed using latent profile analysis (LPA) and multivariate logistic regression analysis. Three latent profiles of SOC were identified: low SOC and low comprehensibility group (29.01%), moderate SOC and high meaningfulness group (40.08%), and high SOC and high manageability group (30.91%). This study found that SOC was impacted by self-perceived severity of the disease and GRRs including optimism, self-esteem, and inner peace ( SOC in patients with advanced cancer exhibited different characteristics. Enhancing positive disease perception and GRRs including optimism, self-esteem, and inner peace may be effective strategies for improving their SOC. Healthcare professionals can formulate strategies such as tailored health education, symptom management, and positive psychological interventions to enhance SOC in patients with advanced cancer.

Atherosclerotic cardiovascular disease (ASCVD) continues to be a major global health burden, with substantial residual cardiovascular risk remaining. Growing evidence highlights the liver’s pivotal role in the onset and development of ASCVD through multiple interconnected pathways. As the metabolic center of the body, the liver regulates the synthesis, secretion, and clearance of several atherogenic lipoproteins while simultaneously serving as a systemic inflammation amplifier, producing cytokines, acute-phase proteins, and coagulation factors. Traditional liver-targeted therapies, such as statins, have demonstrated that regulating liver metabolism can confer significant cardiovascular benefits. Subsequently, advances in nucleic acid-based drugs and in vivo gene-editing tools have broadened this strategy, enabling accurate and durable modulation of hepatic gene expression. However, recent clinical trials suggest that improvements in laboratory biomarkers do not always translate into proportional reductions in major adverse cardiovascular events. Moreover, the long-term safety and durability of lipid nanoparticles and gene-editing platforms remain ongoing concerns. Future research should focus on the classification of patients based on multiple omics data, and distinguish those whose main problem is metabolic disorder from those who are mainly at high risk of inflammation, thereby facilitating personalized therapeutic targeting. Overall, current evidence indicates that the liver represents a convergent therapeutic target for modulating both lipid metabolism and inflammation, offering a promising opportunity for deeper and more durable cardiovascular risk reduction.

This study aimed to investigate the relationship between blood uric acid (UA), serum lipoprotein(a) [Lp(a)], and the severity of neurological damage in patients with acute penetrating artery occlusive cerebral infarction combined with type 2 diabetes mellitus (T2DM). To evaluate the role of UA and Lp(a) levels as independent risk factors for neurological damage severity and poor prognosis, and to observe the therapeutic effect of tanshinone. Clinical data of patients were analyzed to compare differences in indicators between the mild and moderate groups, as well as between groups with good and poor prognosis. Patients in the moderate infarction group showed significantly higher levels of UA, Lp(a), and other biochemical markers, along with higher rates of unhealthy lifestyle habits and comorbidities. UA, Lp(a), and infarct diameter were independent risk factors for poor prognosis. Their combined prediction model demonstrated good sensitivity and specificity. Pre-treatment UA and Lp(a) levels were significantly positively correlated with pre-treatment NIHSS scores and post-treatment mRS scores, respectively. In patients with acute penetrating artery occlusive cerebral infarction combined with T2DM, blood uric acid and serum Lp(a) levels are associated with the severity of neurological damage and serve as independent risk factors for poor prognosis.

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.

Previous research has suggested that high levels of internet use are associated with lower levels of physical activity. However, recent studies have yielded mixed findings. First, we aim to explore the prevalence of internet addiction and sedentary behavior among college students. Second, we examine the relationship between sedentary behavior and body composition. Additionally, we employ latent profile analysis (LPA) to identify subgroups of internet addiction profiles and to explore the associations between these latent profiles and sedentary behavior. This cross-sectional study examined the relationship between sedentary behavior, internet addiction, and body composition among 369 Chinese college students. Sedentary behavior was assessed via self-reported sitting time, internet addiction was measured using a standardized questionnaire, and body composition was evaluated with the InBody 120 device. LPA, an individual-centered method, was used to identify homogeneous subgroups of internet addiction. 42.3 % of students exhibited internet addiction and 72.6 % reported ≥6 h of daily sitting. LPA revealed two distinct profiles of internet addiction-"Regular" (57.2 %) and "Internet addiction" (42.8 %)-highlighting its heterogeneous nature. The findings suggest that age (p = 0.296), gender (p = 0.304), and sedentary time (p = 0.954) may not be the primary factors contributing to these profiles. Policymakers and campus health programs should tailor interventions to distinct internet addiction subgroups. Further research is needed to examine psychological, behavioral, and social contributors, as well as long-term effects. Show less

Social isolation has emerged as an increasingly critical public health issue among adolescents with depression. This study aimed to identify latent subgroups of social isolation based on its manifestations among adolescent patients with depression and to explore the associated influencing factors. A cross-sectional study was conducted from August 2024 to March 2025 at a specialized psychiatric hospital in Nanjing, China. Data were collected using paper-based questionnaires, which included demographic characteristics, the General Social Alienation Scale (GSAS), the Patient Health Questionnaire for Adolescents (PHQ-A), and the Resilience Scale for Chinese Adolescents (RSCA). Latent profile analysis (LPA) was used to classify patterns of social isolation. Chi-square tests, analysis of variance (ANOVA), lasso regression, and multinomial logistic regression were used to analyze profile characteristics and their influencing factors. A total of 412 adolescent patients with depression were included. This study identified three distinct profiles of social isolation: "Low isolation - Fluctuating group" (24.7 %, n = 102), "Moderate isolation - Skeptical group" (39.6 %, n = 163), and "High isolation - Avoidant group" (35.7 %, n = 147). Patients were significantly more likely to be classified into the "High isolation - Avoidant group" if they had siblings, a longer duration of mental illness, more severe depressive symptoms, or lower psychological resilience (all p < 0.05). This study revealed the heterogeneity of social isolation among adolescents with depression through LPA and identified key influencing factors. These findings provide a theoretical foundation for the development of tailored intervention strategies. Show less

This study aimed to assess the knowledge, attitudes, and practices (KAP) of patients with lower limb arteriosclerosis obliterans (ASO) toward their disease. This cross-sectional study was conducted at 3 tertiary hospitals in Chengdu between August 2023 and January 2024 and included patients with lower limb ASO. Data were collected using an interviewer-administered questionnaire that captured demographic information and KAP scores. A latent profile analysis (LPA) was used to identify the KAP patterns among participants. A total of 515 nonproblematic questionnaires were collected, yielding an effective response rate of 95.72%. Among the respondents, 395 (76.85%) were male, with a disease course of 15.96 ± 17.55 months. The knowledge, attitude, and practice scores were 5.27 ± 4.69 (possible range: 0-22), 17.65 ± 2.86 (possible range: 5-25), and 107.63 ± 17.15 (possible range: 33-165), respectively. LPA identified 4 participant profiles: Profile 1 (high attitude, low practice), Profile 2 (low attitude, high practice), Profile 3 (low attitude, low practice), and Profile 4 (high attitude, high practice). Significant differences were found among profiles in residence (P = 0.028), medical insurance (P = 0.043), self-efficacy (P < 0.001), and patient activation (P < 0.001). Patients with lower limb ASO demonstrated inadequate knowledge but moderate levels of attitude and practice. Residence, medical insurance, self-efficacy, and patient activation may affect the KAP patterns of the patients. These findings suggest that tailored interventions targeting distinct patient profiles, while considering broader social determinants of health, may be critical to improving self-management and outcomes.

High-density lipoprotein(a) (Lp(a)) is a well-established independent risk factor for atherosclerotic cardiovascular diseases (ASCVD). However, the interaction between Lp(a), low-density lipoprotein cholesterol (LDL-C), and polygenic risk score (PRS) in cardiovascular diseases has been the subject of relatively limited research. The present study included a total of 346,751 participants from the UK Biobank. According to the guideline of Lp(a), the study subjects were divided into 3 groups: the first group was <75 mmol/L (n = 272,643), the second group was 75 to 125 mmol/L (n = 35,792), and the third group was >125 mmol/L (n = 38,316). Elevated Lp(a) levels were associated with a progressively increased risk of overall cardiovascular events (CVEs), including ischemic stroke (IS), coronary heart disease (CHD), angina pectoris, and myocardial infarction (MI). In contrast, the risks of atrial fibrillation (AF) and heart failure (HF) decreased with higher Lp(a) levels. Additive interaction analyses revealed significant synergistic effects between Lp(a) and LDL-C for CHD (relative excess risk interaction [RERI] = 0.081, attributable proportion of interaction [AP] = 0.046, synergy index [SI] = 1.117), angina pectoris (RERI = 0.112, AP = 0.055, SI = 1.121), and MI (RERI = 0.183, AP = 0.079, SI = 1.161), with MI showing the strongest synergy. Incorporating PRS further amplified these effects, and the RERI (CHD: RERI = 0.721; angina pectoris: RERI = 0.781; MI: RERI = 1.318) and SI (CHD: SI = 2.218; angina pectoris: SI = 1.97; MI: SI = 2.326) were significantly higher than those of the interaction model containing only Lp(a) and LDL-C. In conclusion, Lp(a) and LDL-C show a significant synergistic effect in ASCVD, and this effect is more prominent in individuals with a higher PRS, suggesting that dual lipid management should be strengthened for such populations. While AF and HF may require alternative risk factor management. Show less

Accumulating research has demonstrated a significant association between early-life inflammation and behavioral disorders later in life. However, the effects of early-life inflammation on aggressive behavior in adulthood remain poorly understood. Here, we show that early-life inflammation induced by lipopolysaccharide (LPS) upregulated neuronal dynamin-related protein 1 (DRP1) and impaired mitochondrial function in medial prefrontal cortex (mPFC) of adult mice, thereby increasing aggressive behavior in adulthood. We further identify that CCAAT/enhancer binding protein β (C/EBPβ) is the transcription factor of Dnm1l, which was activated by an increased release of lysophosphatidic acid (LPA) induced by early-life inflammation. Moreover, the overproduction of LPA was due to a specific increase in astrocyte-secreted autotaxin (ATX). Specific knockdown of astrocytic ATX reduced early-life inflammation-induced aggression in wild-type mice, but not in Thy1-C/EBPβ transgenic mice. Remarkably, coenzyme Q10 decreased early-life inflammation-induced aggressive behavior in adult mice. Altogether, these findings provide new insights into the molecular mechanisms by which early inflammation promotes aggressive behavior in adulthood. Show less

During endoscopic endonasal surgery (EES), inferolateral trunk (ILT) sacrifice may be required to efficiently and safely achieve tumor resection within the lateral compartment (LC) of the cavernous sinus (CS). The authors investigated the surgical anatomy and variations of the ILT, aiming to provide practical information to safely expose, coagulate, and transect this artery during EES. In this anatomical study, 24 postmortem, lightly embalmed, colored silicone-injected human head specimens were dissected and 41 sides were examined. The origin, course, branching pattern, and relation of the ILT with surrounding structures were investigated. Clinical charts of patients surgically treated for pituitary adenomas (PAs) with LC invasion from July 2018 to April 2023 at the authors' institution were also retrospectively analyzed. Illustrative cases are provided. The ILT was found in 93% (38/41) of sides, mainly arising from the inferolateral aspect (91%, 30/33 sides) of either the middle or posterior third (82%, 27/33 sides) of the horizontal segment of the internal carotid artery. After a short common trunk (mean length 3 mm), the artery divided into 2 (21%, 8/38) or, more frequently, 3 (74%, 28/38) branches, supplying blood to cranial nerves (CNs) III, IV, V1, V2, V3, and VI and the Gasserian ganglion. While the sympathetic plexus was always located anterior to the ILT, CN VI was found anterior to the ILT in 82% (31/38) of sides. The lateral parasellar ligament (LPL) enwrapped the ILT and its branches in 43% (15/35) of sides. In the coronal plane, the ILT origin was found at the level of the sellar floor (0 ± 1 mm) and the LPL (0 ± 2 mm), both of which can serve as surgical landmarks during lateral transcavernous EES. In the case series of 25 EESs for PAs with LC invasion, the ILT was sacrificed in 5 cases (20%) without any permanent postoperative CN deficits. This study served as a detailed anatomical investigation of the ILT, which is crucial when accessing the LC of the CS. The authors proposed two reliable landmarks to identify the ILT intraoperatively: the sellar floor and the LPL. Furthermore, investigations confirmed that the ILT can be sacrificed without causing permanent CN deficits given the existence of a collateral supply. Show less

Previous studies have reported that IGF-1 single nucleotide polymorphism is associated with milk fat traits, but they are limited to trait association analysis. We previously identified a synonymous mutation c.258 A > G (rs322131043) in IGF-1, which influenced IGF-1 expression and caused differences in metabolism. This study aims to reveal a new regulatory function of IGF-1 c.258 A > G on milk fat metabolism. Livers transcriptomics was used to identify differentially expressed genes between wild type mice (WT) and IGF-1 c.258 A > G mice (Homozygous mutation, Ho). Subsequently, lipid phenotyping, followed by metabolomics of mammary glands was conducted to verify transcriptomic findings. Finally, the potential mechanisms underlying IGF-1 c.258 A > G-induced changes in milk fat metabolism were explored though integrated transcriptomics-metabolomics analysis and Western blot validation. IGF-1 c.258 A > G changed the expression of genes related to lipid metabolism in livers of 8-week-old mice, including a 10-fold ‌lipoprotein lipase (LPL) expression (P < 0.01) and ‌80-90 % downregulation of acyl-CoA thioesterase 3 (Acot3), enoyl-Coenzyme A delta isomerase 3 (Eci3), fatty acid synthase (FASN), and sterol regulatory element binding protein1 (SREBP1) expression (P < 0.01). The milk fat content of Ho dams on the second day of lactation (L2D) was decreased 50 % than that of WT dams (P < 0.05), although there was no significant difference in adipose tissue of 8-week-old WT/Ho mice. The levels of triglycerides, sphingolipids and their related fatty acyl chains (10:0, 26:0, 14:2, 20:4, 11:3, 19:0) in mammary glands of L2D Ho dams were reduced 10-50 % observed by lipid metabolomics. And combined with transcriptomics and Western blot, the data suggested that a ‌2.5-fold upregulation of LPL expression‌ (P < 0.05) may contribute to the milk fat metabolism changes mediated by the ‌ IGF-1 c.258 A > G. This study revealed new function of IGF-1 c.258 A > G on milk fat metabolism, thereby informing the development of targeted genetic breeding on milk fat trait. Show less

Coronary artery anomalies are rare both in coronary angiogram and computed tomography angiography. Hypertrophic cardiomyopathy (HCM) is the most frequent inherited cardiac disease. The phenotype of HCM associated with anomalous coronary origin is not commonly seen especially in children. We describe a case series of two children with HCM combined right coronary artery (RCA) originated from left coronary sinus. Case 1 was a 9-month-old female with HCM coexisted with anomalous origin of RCA has different clinical presentation, and it maybe due to different gene mutation. Show less
