Abdominal aortic aneurysm (AAA) is a life-threatening vascular disease with no effective pharmacological treatments. The causal role of triglycerides (TGs) in AAA development remains unclear and controversial. Mendelian randomization was applied to assess causal relationships between lipoproteins, circulating proteins, metabolites, and the risk of AAA. To test the hypothesis that elevated plasma TG levels accelerate AAA development, we used Mendelian randomization analyses integrating genetic, proteomic, and metabolomic data identified causal relationships between elevated TG-rich lipoproteins, TG metabolism-related proteins/metabolites, and AAA risk. In the angiotensin II infusion AAA model, most These findings identify hypertriglyceridemia as a key contributor to AAA pathogenesis and suggest that targeting TG-rich lipoproteins may be a promising therapeutic strategy for AAA.

Cholesterol (CH) plays a crucial role in enhancing the membrane stability of drug delivery systems (DDS). However, its association with conditions such as hyperlipidemia often leads to criticism, overshadowing its influence on the biological effects of formulations. In this study, we reevaluated the delivery effect of CH using widely applied lipid microspheres (LM) as a model DDS. We conducted comprehensive investigations into the impact of CH on the distribution, cell uptake, and protein corona (PC) of LM at sites of cardiovascular inflammatory injury. The results demonstrated that moderate CH promoted the accumulation of LM at inflamed cardiac and vascular sites without exacerbating damage while partially mitigating pathological damage. Then, the slow cellular uptake rate observed for CH@LM contributed to a prolonged duration of drug efficacy. Network pharmacology and molecular docking analyses revealed that CH depended on LM and exerted its biological effects by modulating peroxisome proliferator-activated receptor gamma (PPAR-γ) expression in vascular endothelial cells and estrogen receptor alpha (ERα) protein levels in myocardial cells, thereby enhancing LM uptake at cardiovascular inflammation sites. Proteomics analysis unveiled a serum adsorption pattern for CH@LM under inflammatory conditions showing significant adsorption with CH metabolism-related apolipoprotein family members such as apolipoprotein A-V (Apoa5); this may be a major contributing factor to their prolonged circulation Show less

Pancreatic cancer (PC), characterized by the absence of effective biomarkers and therapies, remains highly fatal. Data regarding the correlations between PC risk and individual plasma proteome known for minimally invasive biomarkers are scarce. Here, we analyzed 1,345 human plasma proteins using proteome-wide association studies, identifying 78 proteins significantly associated with PC risk. Of these, four proteins (ROR1, FN1, APOA5, and ABO) showed the most substantial causal link to PC, confirmed through Mendelian randomization and colocalization analyses. Data from two clinical cohorts further demonstrated that FN1 and ABO were notably overexpressed in both blood and tumor samples from PC patients, compared to healthy controls or para-tumor tissues. Additionally, elevated FN1 and ABO levels correlated with shorter median survival in patients. Multiple drugs targeting FN1 or ROR1 are available or in clinical trials. These findings suggest that plasma protein FN1 associated with PC holds potential as both prognostic biomarkers and therapeutic targets. Show less

To explore the correlation between different traditional Chinese medicine (TCM) constitution types and apolipoprotein B (ApoB) in patients with hyperuricemia (HUA) and to investigate the relationships between TCM constitutions, uric acid levels, and various cardiovascular risk factors. A cross-sectional study involving 683 patients diagnosed with HUA was conducted. Patients' TCM constitutions were classified using the standardise "Classification and Determination of TCM Constitution" questionnaire. Serum uric acid (UA), lipid profiles, ApoB, and homocysteine (Hcy) levels were measured. Among 683 HUA patients, phlegm-dampness (22.99% ) and damp-heat constitution (20.06% ) were the most common TCM constitution types. UA, ApoB, and Hcy levels in patients with phlegm-damp constitution were significantly higher than those in other constitutions (P< 0.05). UA levels were negatively correlated with HDL-C (r=-0.472, P= 0.027) and positively correlated with ApoB (r= 0.618, P= 0.012) and Hcy (r= 0.492, P= 0.018). Phlegm-damp and damp-heat constitutions are the most common TCM constitution types in HUA patients and are associated with higher levels of UA, ApoB, and Hcy. These constitutional types are independently associated with increased cardiovascular risk. Show less

Cholecystectomy alters lipid profiles and is associated with the risk of major adverse cardiac and cerebrovascular events (MACCE), yet the results are ambiguous. To assess the causal effects of cholecystectomy on blood lipid levels and risks of MACCE, we performed Mendelian randomization (MR) aiming to reduce confounding. We used genetic data on gallbladder removal, lipid levels, and MACCE from public databases. MR analysis estimated causal effects using genetic variants as instruments. Enrichment analysis identified relevant metabolic pathways, while multivariable MR evaluated specific lipid subtypes. Expression Quantitative Trait Loci MR pinpointed key genes, with cellular distribution insights from single-cell sequencing. Cholecystectomy was associated with delayed onset of angina, coronary heart disease, heart failure, myocardial infarction, and stroke. The ApoB/ApoA1 ratio was a key mediator, and the LPL gene influenced lipid-related cardiovascular risk. Cholecystectomy may reduce cardiovascular risks by lowering the ApoB/ApoA1 ratio, which highlights the role of lipid regulation in mitigating cardiovascular risk post-cholecystectomy. Show less

To assess the predictive ability of baseline serum apolipoprotein B (ApoB) and the ratio of ApoB to apolipoprotein A1 (ApoB/ApoA1 ratio) for dyslipidemia risk in patients receiving second-generation antipsychotics (SGAs). Medical records of patients hospitalized between March 2019 and March 2025 were retrospectively reviewed. The optimal cut-off points for baseline serum ApoB levels and the ApoB/ApoA1 ratio were identified using a maximally selected log-rank statistic analysis. Multivariable Cox proportional hazards models estimated hazard ratios (HRs) with 95% confidence intervals (95% CIs). The Kaplan-Meier method with Log rank testing was used to compare the cumulative incidence of dyslipidemia between groups defined by these cut-off points. Of 311 enrolled patients, 33 (10.6%) lacking baseline ApoA1 measurements were excluded from ApoB/ApoA1 ratio analyses. The optimal cut-off points were 0.70 g/L for baseline ApoB and 0.45 for the ApoB/ApoA1 ratio. Multivariable Cox proportional hazards models, fully adjusted for covariates, demonstrated significantly elevated dyslipidemia risk for patients exceeding these thresholds vs low-risk groups: adjusted HR 2.98 (95% CI: 2.05-4.32, p < 0.001) for high ApoB and 3.17 (95% CI: 1.62-6.22, p = 0.001) for high ApoB/ApoA1 ratio. Continuous analysis showed each 0.1 g/L ApoB increase conferred a 34% higher risk (adjusted HR 1.34, 95% CI: 1.21-1.48, p < 0.001), while each 0.1-unit ApoB/ApoA1 ratio increase conferred a 20% higher risk (adjusted HR 1.20, 95% CI: 1.10-1.30, p < 0.001). Kaplan-Meier curves confirmed significantly higher cumulative dyslipidemia incidence in high vs low groups for both markers (Log rank test, both p < 0.001). Baseline serum ApoB levels and the ApoB/ApoA1 ratio are valuable risk markers for dyslipidemia in patients treated with SGAs. Show less

Pentadecanoic acid (PEA), an odd-chain fatty acid derived from diet by the gut microbiome, has garnered increasing attention for its systemic health-promoting properties. Its potential role in bladder cancer (BC) occurrence and invasion, however, remains unclear. Large-scale cohorts' analyses were performed to assess the association between dietary PEA and BC occurrence and invasion. In vitro and in vivo experiments, including EJ and T24 BC cell assays and a BBN-induced mouse model, were conducted to experimentally assess the impact of PEA on BC. Serum proteomics, gut microbiome, and targeted fecal lipidomics analyses were employed to explore the underlying mechanisms. Dietary PEA was negatively associated with BC occurrence and invasion in cohort analyses. PEA suppressed EJ and T24 BC cell migration, invasion, and proliferation, while inhibiting BC development in a BBN-induced mouse model. In vivo serum proteomics identified differentially expressed lipid-related proteins (e.g., Apoe and Apob) following PEA treatment, implicating its modulation of lipid metabolism pathways. Considering the essential role of the gut-bladder axis, the gut microbiome analysis exhibited that PEA markedly altered bacteria (e.g., g_Alistipes) and fungi (e.g., o_Erysiphales, g_Teberdinia, and g_Gibberella), with concomitant lipid metabolism changes. Furthermore, targeted fecal lipidomics demonstrated the shifts in key lipids, such as phosphatidylethanolamines (PE) involved in essential lipid clusters, suggesting regulation by gut microbiome linked to BC development. Collectively, our findings demonstrate that PEA mitigates BC by reshaping the gut microbiome and modulating lipid metabolism, providing new insights into its molecular and therapeutic potential.

Due to the growth in the global consumption of assisted reproductive technology (ART), it is possible that long-term health impacts on offspring have come into focus. ART has offered a welcome solution to infertility, but the fear has been on its effect on the metabolic health of children born on their behalf. Past studies indicate that ART-conceived individuals can have characteristic metabolic profiles relative to their naturally conceived (NC) peers and are therefore potentially predisposed to changes in lipid and glucose handling. Physiopathological glycolipid metabolism, a hallmark of cardiometabolic health, is believed to be modulated not only by environmental and other external factors but also by intracellular regulation proteins, including sterol regulatory element-binding protein (SREBP) and miR-33, although there is little evidence on the effects of ART on these regulatory pathways in early childhood. This paper sought to compare the glycolipid metabolic profile of the kids who are in preschool age and who were conceived through ART and kids who were NC. The second aim was to study the expression of SREBP-1/2 and miR-33 in peripheral blood and the possible nature of the role of these players in regulating early-life metabolism. A total of 220 children aged between 3 and 6 years were recruited of which complete data has been obtained from 206 children out of 98 that were conceived via in vitro fertilization/intracytoplasmic sperm injection (ICSI) (ART group) and 108 that were conceived naturally (NC group). Anthropometric measures-such as body weight, height, and waist circumference-to determine physical growth and obesity status were taken. Biochemical variables, triglyceride (TG), high-density lipoprotein cholesterol (HDL-C), apolipoprotein A1 (ApoA1), apolipoprotein B (ApoB), fasting serum insulin (FINS), and homeostatic model assessment of insulin resistance (HOMA-IR) were determined. A centrifugal column was used to obtain peripheral blood RNA, and relative gene expression levels of SREBP-1, SREBP-2, miR-33a, and miR-33b were measured by qPCR. Compared with the IVF group, children in the ICSI group had significantly lower weight, height, and waist circumference ( Our data suggest that although children born by means of ART are otherwise normal in their glycolipid metabolism, they are more prone to overweight and obesity and have different biochemical and molecular characteristics than NC children. The upregulation of miR-33b, SREBP-1, and SREBP-2 observed indicates that ART can play a role in regulating the process of glycolipid metabolism during early childhood at a molecular level. Such alterations might not present the form of a blatant metabolic condition at this age but may consist of initial symptoms of future troublesome metabolic health. Prolonged follow-up of the ART offspring and additional mechanistic work are desirable to be able to determine whether these early changes are the underlying reasons behind higher metabolic risk as adults.

To establish a short-term high-fat/high-cholesterol (HFHC) diet-induced Metabolic dysfunction-associated steatotic liver disease (MASLD) mouse model, and evaluate the effects of rapamycin (RaPa) and chloroquine (CQ) on this model to explore their therapeutic potential and side effects. An early MASLD mouse model was constructed via short-term HFHC diet feeding. Model mice were intraperitoneally injected with RaPa or CQ. Drug effects were analyzed on body weight, liver weight, lipid metabolism-related genes (APOB, FASN, PLIN2), inflammatory factors (IL-6, IL-10), and fibrosis markers (LOX, Col-1α-1, CCL2, TGFβ1, PDGFRβ, α-SMA) at mRNA and protein levels. RaPa ameliorated body weight and liver weight in early MASLD mice, downregulated FASN and PLIN2 expression, upregulated IL-10 mRNA levels, and alleviated hepatic steatosis, but induced metabolic disorders such as Insulin resistance and hyperlipidemia. In contrast, CQ promoted FASN and PLIN2 expression, exacerbated hepatic steatosis, reduced IL-10 mRNA levels, and upregulated fibrosis-related markers (LOX, TGFβ1, PDGFRβ, α-SMA) at both mRNA and protein levels, thereby driving MASLD progression to liver fibrosis. Notably, CQ improved metabolic abnormalities in model mice, including obesity, hyperlipidemia, and Insulin resistance. RaPa and CQ exhibit dual effects on early MASLD: RaPa alleviates hepatic steatosis but exacerbates metabolic disorders, whereas CQ improves metabolic abnormalities but accelerates liver fibrosis. This paradox highlights the need to balance metabolic regulation and liver injury prevention in MASLD treatment, providing critical experimental insights for targeted drug development. Show less

End-stage renal disease (ESRD) is associated with high morbidity and mortality. Identifying patients with stage 4 chronic kidney disease (CKD) at risk of short-term progression to ESRD remains challenging. Accurate prediction can improve advanced care planning and patient outcomes. This study aimed to develop and validate a machine learning (ML) model for predicting progression within 25 weeks (approximately six months) of ESRD in patients with stage 4 CKD. Electronic health records (EHRs) of patients with stage 4 CKD were analyzed. Nine ML models including Ridge regression (Ridge), random forest (RF), and eXtreme Gradient Boosting (XGBoost) were used to predict short-term progression to ESRD within 25 weeks. The models were trained and externally validated using the data of 346 and 105 patients. Of the 451 patients with stage 4 CKD, 219 developed ESRD. Among the evaluated models, XGBoost demonstrated the best overall performance. In the internal validation, it achieved an area under the curve (AUC) of 0.93, an accuracy of 0.90, and an F1 score of 0.89. In the external validation, XGBoost maintained the highest AUC (0.85), accuracy (0.79), and F1 score (0.79), along with the highest average precision (0.89) and a low log-loss (0.48), indicating strong discriminative ability and good generalizability. The top predictive features included high-density lipoprotein cholesterol, Alb, Cys C, ApoB, FGB, Bun, Neutrophil, and Total cholesterol. This study demonstrated the feasibility of ML for assessing ESRD prognosis based on easily accessible clinical features. XGBoost demonstrated superior performance in both internal and external validation, suggesting its potential for future patient screening. Show less

Lipid metabolism is pivotal in diabetic retinopathy (DR) development. Nevertheless, the relationship between lipid-lowering drugs and the risk of DR remains a topic of debate. This study employed Mendelian randomization (MR) to investigate the potential effects of pharmacological lipid-lowering targets on DR and to clarify the causal association between blood lipid characteristics and DR. The data comprised genetic variations related to lipid traits and genetic variations associated with lipid-lowering drug targets obtained from the Global Lipid Consortium. Total DR, non-proliferative DR (NPDR), and proliferative DR (PDR) were sourced from the Finnish R9 database. Lipid-lowering drug targets were tested using inverse variance-weighted MR (IVW-MR) and statistics-based MR (SMR). Colocalization and mediation analysis were conducted to validate the results and explore potential mediating factors. A reduced risk of total DR and NPDR was associated with genetically improved 3-hydroxy-3-methylglutaryl-CoA reductase (HMGCR) (OR = 0.62; 95% CI: 0.46-0.83; This Mendelian randomization study suggests that abnormalities in triglyceride (TG) levels serve as a pathogenic element in DR. Of the nine lipid-lowering drug targets assessed, HMGCR and APOB have emerged as potential promising targets for managing NPDR.

Dysregulation of lipid metabolism often occurs in rheumatoid arthritis (RA) patients, and Apolipoprotein E (APOE) is a prominent apolipoprotein involved in regulating lipid metabolism. We aimed to investigate the relationship between APOE genotypes with serum lipids and cardiovascular disease (CVD) risk in RA patients. We recruited 200 RA patients from the Affiliated Hospital of Nanjing University of Chinese Medicine. The high-resolution melting method was used to analyze genomic DNA extracted from the peripheral blood of RA patients. Immunoturbidimetric assay or Colorimetric assay was used to measure clinical laboratory results of RA patients. The differences in clinical laboratory results of APOE genotypes were compared, and the correlation between various indexes and APOE concentration in RA patients with APOE genotypes was analyzed. RA patients with ε2/ε3 genotype had lower levels of total cholesterol (TC), low-density lipoprotein (LDL), and apolipoprotein B (APOB) compared with ε3/ε4 genotype patients (p < 0.05). RA patients with ε3/ε4 genotype had significantly higher small dense low-density lipoprotein (sdLDL) and lipoprotein(a) (Lp(a)) compared with ε2/ε3 genotype patients (p < 0.05). Moreover, the APOE concentration of ε2/ε3 genotype was significantly higher compared with ε3/ε4 genotype (p < 0.001), and the APOE concentration of ε2/ε3 genotype was significantly positively correlated with high-density lipoprotein (HDL) and apolipoprotein A (APOA) (p < 0.05), while the APOE concentration of the ε3/ε4 genotype was positively correlated with LDL, APOB, and Lp(a) (p < 0.05). This study provides strong evidence that APOE polymorphism is associated with lipoprotein metabolism. The independent risk factors for CVD (sdLDL and Lp(a)), are significantly elevated in ε3/ε4 genotype. APOE concentration is significantly elevated in ε2/ε3 genotype and positively correlated with protective factors for CVD, whereas the opposite is observed in the ε3/ε4 genotype. Therefore, RA patients with ε3/ε4 genotype exhibited dysregulated lipid metabolism, increasing the risk of CVD. Key points • In RA patients with ε2/ε3 genotype have lower levels of TC, LDL, and APOB compared with ε3/ε4 genotype. • In RA patients carrying ε3/ε4 genotype have higher levels of sdLDL and Lp(a) compared to carriers of ε2/ε3 genotype. • The role of APOE concentration in RA patients is closely related to APOE genotypes.

A comprehensive understanding of protein corona (PC) composition is critical for engineering nanoparticles (NPs) with optimal safety and therapeutic performance, because the PC governs NP pharmacokinetics, biodistribution, and cellular interactions. Yet systematic analyses are hampered by the absence of standardized, richly annotated data sets. Here, we introduce the Protein Corona Database (PC-DB), which compiles data from 83 studies (2000-2024) and integrates 817 NP formulations with quantitative profiles of 2497 adsorbed proteins. The PC-DB exposes pronounced heterogeneity in NP materials (metal 28.8%, silica 22.8%, lipid-based 14.8%), surface modifications, sizes (1-1400 nm), and ζ-potentials (-70 to +70 mV). Subsequent meta-analysis shows that silica, polystyrene, and lipid-based NPs smaller than 100 nm with moderately negative to neutral ζ-potentials preferentially bind the lipoproteins APOE and APOB-100, which are linked to receptor-mediated uptake and enhanced delivery efficiency. In contrast, metal and metal-oxide NPs carrying highly negative surface charge enrich complement component C3, indicating a greater likelihood of immune recognition and clearance. Interpretable machine learning models (LightGBM and XGBoost; ROC-AUC > 0.85) confirm NP size, ζ-potential, and incubation time as the most influential predictors of protein adsorption. These results delineate how physicochemical parameters dictate PC composition and illustrate the power of predictive modeling to guide rational NP design. Show less

Lipid metabolism abnormalities and inflammation have been implicated in gallstone disease (GSD) development, but the causal relationships and potential mediation effects among lipid metabolites, inflammatory factors, and GSD remain unclear. The aim of this study is to explore the causal relationships among these 3 factors. This study employed 2-sample Mendelian Randomization (TSMR) and 2-step MR to investigate the causal relationships and potential mediation effects among 91 inflammatory factors, 6 lipid metabolism-related molecules (HDL-C, LDL-C, TG, total cholesterol, ApoA1, and ApoB), and GSD. We opted for 4 distinct MR analysis methods including inverse variance weighted method, weighted median method, MR-Egger regression method and MR-PRESSO analysis. Sensitivity analyses included MR-Egger intercept tests, Cochran's Q statistic, Steiger tests, and leave-one-out analyses. Product of coefficients method was used to estimate mediation proportion. TSMR analysis revealed that every 1-unit increase in low-density lipoprotein cholesterol (LDL-C), total cholesterol (TC), apolipoprotein A1 (ApoA1), and apolipoprotein B (ApoB), the risk of GSD decreased by 16.5%, 10.2%, 8.4%, and 13.1%, respectively. Inflammatory factors such as Natural killer cell receptor 2B4 (CD244), Macrophage colony-stimulating factor 1 (CSF-1), and interleukin-18 receptor 1 (IL-18R1) were identified as risk factors for GSD, while Fibroblast growth factor 19 levels (FGF19), Interleukin-1-alpha levels (IL-1α), and Interleukin-8 levels (IL-8) were found to be protective. Mediation analysis through 2-step MR identified potential pathways involving ApoA1--IL-8--GSD (P = .084) and IL-1α--ApoB--GSD (P = .117). This study provides robust evidence of causal links between specific lipid metabolites and GSD, as well as suggestive causal associations for several inflammatory factors. However, mediation analysis did not support significant roles for lipids or inflammatory factors as mediators in GSD pathogenesis. Future research could be further pursued in areas such as drug target intervention and mechanistic studies. Show less

Abnormalities in lipid metabolism play an important role in diabetic macular edema (DME), and the aim of this study was to investigate the correlation between ApoB/A1 levels and best corrected visual acuity (BCVA) and macular microstructural changes in DME patients after anti-VEGF treatment. Through a retrospective cohort analysis of 61 patients (61 eyes) with non-proliferative diabetic retinopathy combined with macular edema treated with 3 + PRN anti-VEGF regimen and followed up for three months, grouped by median ApoB/A1, the differences between the efficacy indexes of the two groups were compared. The results showed that the macular edema regression rate was significantly higher in the high ApoB/A1 ratio group than in the low ratio group at one month after treatment(P < 0.05), and at three months after treatment, the high ApoB/A1 ratio group was better than the low ratio group in BCVA improvement (58.1% vs. 26.7%), inner retinal layer restoration (38.7% vs. 10.0%), and hyperreflective foci (HF) reduction (41.9% vs. 6.7%). aspects were better than those in the low ratio group (P < 0.05). The results of ordered logistic regression analysis showed that the ApoB/A1 ratio was significantly correlated with the change in macular edema at one month after treatment and the change in the number of HF at three months after treatment. Conclusions showed that the ApoB/A1 ratio was significantly correlated with short-term improvement of BCVA and macular microstructure after anti-VEGF treatment in DME patients, and it is expected to be used as an objective biomarker for assessing the efficacy of anti-VEGF treatment in DME patients.

Coronary artery disease (CAD) is showing a trend toward earlier onset. Premature CAD (PCAD) is clinically defined as CAD with onset before the age of 55 in males and 65 in females. Notably, many young patients subsequently hospitalized with acute cardiovascular events had undergone annual physical examinations before hospitalization, yet were not identified as high-risk by current risk stratification guidelines or traditional risk assessment tools. This study aims to investigate the diagnostic capacity of novel inflammatory biomarkers (including the monocyte-to-high-density lipoprotein cholesterol ratio (MHR), platelet-to-lymphocyte ratio (PLR), neutrophil-to-lymphocyte ratio (NLR), lymphocyte-to-monocyte ratio (LMR), apolipoprotein B to apolipoprotein A-1 ratio (apoB/apoA-1), and low-density lipoprotein cholesterol to high-density lipoprotein cholesterol ratio (LDL-c/HDL-c)) for PCAD, thereby providing the evidence-based foundation for PCAD screening. A total of 1,012 young subjects (male<55 years, female<65 years) undergoing diagnostic coronary angiography (CAG) at the Third Affiliated Hospital of Zunyi Medical University (from January 2022 to February 2023) were retrospectively analyzed. We stratified 1,012 eligible participants into two groups: 521 angiographically confirmed PCAD cases and 491 controls with normal coronary arteries. Comprehensive baseline characteristics, including cardiovascular risk profiles and core laboratory-measured inflammatory markers, were recorded. The Mann-Whitney U test and binary logistic regression analysis were employed to assess the associations between inflammatory biomarkers and PCAD. The areas under the receiver operating characteristic (ROC) curves (AUCs) were calculated to evaluate their diagnostic performance for PCAD. The odds ratio (OR) values for MHR, NLR, LDL-c/HDL-c, and apoB/apoA-1 were 5.592 (95% CI: 2.886-7.836), 1.671 (95% CI: 1.500-1.861), 1.663 (95% CI: 1.419-1.950), and 6.268 (95% CI: 2.765-8.213), respectively (all The apoB/apoA-1 outperformed MHR, NLR, and LDL-c/HDL-c as an inflammatory biomarker in PCAD. Its diagnostic capacity was notably enhanced in ACS subgroups. A comprehensive model combining apoB/apoA-1 with traditional risk factors demonstrated exceptional accuracy. Incorporating this biomarker into routine screening protocols could significantly strengthen preventive strategies. Show less

Pulmonary Hypertension (PH) is a significant contributor to cardiac mortality in Dilated Cardiomyopathy (DCM) patients. Inflammatory processes and oxidative stress play pivotal roles in the advancement of Pulmonary Hypertension (PH). The Monocyte-to-High-- Density-Lipoprotein Cholesterol Ratio (MHR), a newly identified biomarker indicative of inflammatory and oxidative stress, has not been extensively researched in the context of pulmonary hypertension, especially within the scope of dilated cardiomyopathy. Given the reason mentioned above, our research explores the correlation between the MHR and the severity of PH in patients suffering from DCM. In this study, we conducted a retrospective review of medical data from 107 individuals diagnosed with non-ischemic DCM, evaluating their clinical profiles, biochemical indicators, MHR, and echocardiographic parameters. We analyzed the relationships between Pulmonary Arterial Systolic Pressure (PASP) and the Ejection Fraction of the Left Ventricle (LVEF). Utilizing logistic regression analysis, we determined the predictors of PH. Findings indicated that the DCM-PH group exhibited a significantly larger male population and elevated New York Heart Association (NYHA) classification scores (both with p-values <0.001 and 0.01, respectively) compared to the DCM-only group. A positive association was observed between the PASP and parameters, such as the Dimensions of the Left Atrium (LAD) and Left Ventricle in Systole (LVDs), Monocyte (M) levels, Direct Bilirubin (DB), and MHR. Conversely, an inverse relationship was noted with serum lipid profiles, including Total Cholesterol (TC), HDL Cholesterol (HDL-c), and apolipoprotein A1. LVEF demonstrated positive linkage with the same lipid profiles and the Left Ventricular Posterior Wall Thickness (LVPWT) yet showed negative correlations with the NYHA classification, Red Blood Cell Distribution Width Standard Deviation (RDW-SD), Total Bilirubin (TB), Direct Bilirubin (DB), and dimensions of the left ventricle in diastole and systole, as well as MHR. Through logistic regression analysis, several factors were recognized as significant predictors for the severity of PH within the DCM cohort, with weight (OR1.20, CI 1.022-1.409, p=0.026), RDW-SD (OR1.988, CI 1.015-3.895, p=0.045), LVPW (OR3.577, CI 1.307-9.792, p=0.013), LVDd (OR1.333, CI 1.058-1.680, p=0.015), MHR (OR3.575, CI 1.502-8.506, p=0.032), and TB (OR1.416, CI 1.014-1.979, p=0.041) showing positive associations, while apoB (OR0.001 CI0.001-0.824, p=0.045) exhibiting negative associations, all with p-values <0.05. Higher MHR and LVD correlate with increased PASP and reduced LVEF in DCMPH patients. MHR and LVPW are independent predictors of PH severity, indicating their potential as novel severity markers in DCM-related PH. Show less

Metabolic diseases such as high blood lipids, high blood sugar, and disrupted gut microbiota pose a serious threat to people's physical health. The occurrence of these diseases is closely related to the lack of nutrients in daily rice staple foods, but there is a lack of comprehensive analysis of the underlying mechanisms. This study used fully nutritious brown rice as raw material, and after germination under various stress conditions, it significantly increased the levels of gamma aminobutyric acid (GABA, four carbon non protein amino acid), resistant starch, flavonoids, and other components that regulate metabolic diseases. Using rats as experimental subjects, a model of hyperlipidemia and hyperglycemia was constructed, with rice consumption as the control. The experimental period was 8 weeks. Research has found that feeding sprouted brown rice can significantly improve the accumulation of white fat in the liver caused by a high-fat diet, significantly reduce TC, TG, LDL-C, apoB, HL, LPL, and LCAT, significantly increase HDL-C and apoA1, and significantly reduce the levels of inflammatory factors IL-6 and TNF-α. Therefore, consuming sprouted brown rice can reduce the risk of hyperlipidemia, inflammation, and tumor occurrence by promoting fat breakdown, and can also increase the abundance of metabolic-promoting microorganisms (especially Euryarchaeota and Lactobacillus) in the intestine, improving the entire metabolic ecological network of rats.

Obesity and dysregulated cytokine levels are prevalent in schizophrenia patients undergoing antipsychotic treatment. While cytokines are implicated in obesity, their relationship with psychopathology in schizophrenia remains underexplored. This study investigated associations between body mass index (BMI), cytokine levels, and clinical symptoms in chronic schizophrenia patients. In this cross-sectional study,201chronic schizophrenia patients (Chinese Han population) were stratified into high BMI (BMI≥25kg/m A significant negative correlation was observed between BMI and IL-2( Higher BMI in chronic schizophrenia is associated with reduced IL-2 levels, attenuated negative symptoms, and adverse lipid profiles. TNF-α may modulate psychopathology severity. These findings highlight complex interactions between metabolic dysregulation, immune markers, and clinical manifestations in schizophrenia. Show less

In Traditional Chinese Medicine (TCM), dampness is a pathogenic factor arising from impaired production and transportation of bodily fluids. While Fuling Zexie decoction (FLZXD) has demonstrated therapeutic efficacy in dampness constitution (DC) treatment, the material basis underlying its constitutional modulatory effects remains unclear. This study proposes objective indicators for the differentiation and therapeutic evaluation of DC and elucidates the material basis of FLZXD in DC treatment. Serum exosome proteomic profiling was conducted across two independent cohorts to identify DC-related indicators and assess the therapeutic efficacy of FLZXD in DC-associated hyperlipidemia (DC-hyperlipidemia). The bioactive compounds of FLZXD were prioritized through a comprehensive analysis of patent documentation and network pharmacology, with subsequent validation of DC-related targets using enzyme-linked immunosorbent assay (ELISA). Proteomic analysis of serum exosomes revealed signatures that differentiate individuals with a balanced constitution (BC) from those with DC. The differentially expressed proteins (DEPs) were enriched predominantly in pathways related to the complement cascade and cardiovascular diseases. FLZXD demonstrated therapeutic efficacy against DC-hyperlipidemia, as evidenced by the reversal of DEPs expression following treatment, which was supported by the patentable findings and network pharmacology analysis. Through experimental validation and pharmacological evidence, the active herbs of FLZXD (Fuling, Zexie and Baizhu, collectively referred to as FZB) were identified, and a total of 73 putative therapeutic targets involved in the dampness-resolving effects of FZB were revealed. Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment further confirmed that FLZXD exerts its anti-dampness effects primarily through regulation of the complement and coagulation cascades. Among eight candidate indicators specifically associated with DC, four proteins were validated via ELISA, indicating potential utility for the differentiation of DC. The sensitivity (%), specificity (%), fold change (FC), p-value, and area under the curve (AUC) for each indicator were as follows: apolipoprotein B-100 (APOB) (100.00, 80.00, 0.63, 0.0051, 0.94), complement factor H-related protein 1 (CFHR1) (90.00, 100.00, 0.55, 0.0001, 0.98), alpha-1-acid glycoprotein 1 (ORM1) (100.00, 80.00, 0.71, 0.0043, 0.92), and pigment epithelium-derived factor (SERPINF1) (90.00, 70.00, 0.66, 0.0002, 0.87). The integrative approach, combining proteomic profiling, network pharmacology analysis, and clinical validation, establishes an integrative approach for research on TCM constitutions. This approach provides (1) molecular insights into the differentiation of DC, (2) a foundation for mechanism-based, targeted therapeutic strategies, and (3) enhanced patient stratification to support personalized treatment approaches.

Increasing evidence underscores the driving role of coding and non-coding variants in cancer development. Analyzing gene sets in biological processes offers deeper insights into the molecular mechanisms of carcinogenesis. Here, we developed geMER to identify candidate driver genes genome-wide by detecting mutation enrichment regions within coding and non-coding elements. We subsequently designed a pipeline to identify a core driver gene set (CDGS) that broadly promotes carcinogenesis across multiple cancers. CDGS comprising 25 genes for 25 cancers displayed instability in DNA aberrations. Variants within the TTN enrichment region may influence the folding of the I-set domain by altering local polarity or side-chain chemistry properties of amino acids, potentially disrupting its antigen-binding capacity in LUAD. Multi-omics analysis revealed that APOB emerged as a candidate oncogene in LIHC, whose genetic alterations within the enrichment region may activate key TFs, upregulate DNA methylation levels, modulate critical histone modifications, and enhance transcriptional activity in the HepG2 and A549 cell lines compared to Panc1. Additionally, CDGS mutation status was an independent prognostic factor for the pan-cancer cohort. High-risk patients tended to develop an immunosuppressive microenvironment and demonstrated a higher likelihood of responding to ICI therapy. Finally, we provided a user-friendly web interface to explore candidate driver genes using geMER ( http://bio-bigdata.hrbmu.edu.cn/geMER/ ). Show less
