BACKGROUND:Early-onset gastric cancer (EOGC), diagnosed before age 45, demonstrates distinct clinicopathological features and poorer prognosis. Current screening strategies lack sensitivity in young populations, while Helicobacter pylori (H. pylori) virulence genotypes (e.g., cagA, vacA) remain underutilized in risk stratification. To develop and validate a diagnostic model combining clinical characteristics and H. pylori virulence serological detection of virulence factors to optimize EOGC risk stratification. METHODS:In this multicenter case-control study, 200 histologically confirmed EOGC patients and 600 age-matched controls (non-malignant gastric conditions) were enrolled from LiShui Hospital (2023-2024). Clinical parameters, H. pylori infection status (13C-urea breath test), and virulence genotypes (cagA, vacA; ELISA) were analyzed. Multivariable logistic regression identified independent risk factors, followed by risk score development and internal validation (1000 bootstrap replicates). RESULTS:EOGC patients exhibited higher prevalence of persistent epigastric pain (68.5% vs. 32.1%; P<0.001), significant weight loss (6.2 vs. 2.1 kg; P<0.01), and H. pylori infection (85.0% vs. 52.3%; P<0.001). Virulent genotypes were enriched in EOGC: cagA+ (72.5% vs. 45.6%; P<0.01) and vacA s1/m1 (65.0% vs. 38.2%; P<0.01). The final model included five predictors: persistent pain (adjusted odds ratio [aOR]=2.85, 95% CI:1.92-4.23), cagA+ (aOR=3.12, CI: 2.01-4.85), anemia (Hb<110 g/L; aOR=2.34, CI: 1.56-3.51), thrombocytosis (>300×109/L; aOR=1.98, CI: 1.32-2.96), and weight loss >2.1 kg (aOR=2.57, CI: 1.21-2.73). A score ≥3 indicated high risk, achieving 86.5% sensitivity and 82.3% specificity (AUC=0.89, CI: 0.85-0.93). CONCLUSIONS:This novel model integrates accessible clinical and microbiological markers to stratify EOGC risk with high accuracy, providing a cost-effective tool for prioritizing endoscopic evaluation in young symptomatic individuals.
OBJECTIVE:High triglyceride (TG) levels complicate the diagnosis of acute pancreatitis (AP) due to delayed lipid testing. This study evaluates the diagnostic value of inflammatory indices, particularly the platelet-to-lymphocyte ratio (PLR) and systemic inflammation response index (SIRI), for identifying hyperlipidemic acute pancreatitis (HLAP). METHODS:A retrospective cohort study analyzed 140 AP patients (59 HLAP, 81 non-HLAP) admitted between January 2023 and December 2024. The HLAP group was further stratified into gray-zone (HLAP-G) and typical (HLAP-S) subgroups. Healthy controls (HC, n=80) and individuals with simple hypertriglyceridemia (HTG, n=80) were included for comparison. Inflammatory indices (PLR, SIRI, NLR, MLR, SII) were calculated from admission blood counts. Diagnostic performance was assessed using ROC analysis, and a combined model (PLR+SIRI+TG) was developed and validated in an external cohort. Dynamic changes of PLR and SIRI were evaluated at 1, 6, and 12 hours post-admission. RESULTS:PLR, SIRI, and other indices were significantly higher in the HLAP group than in the non-HLAP, HTG, and HC groups (all P < 0.01), showing a stepwise increase from HC to HLAP-S. SIRI demonstrated the highest diagnostic efficacy for HLAP (AUC=0.973, sensitivity =91.5%, specificity =96.3%), followed by PLR (AUC=0.960). The combined model achieved the highest AUC (0.988), with external validation confirming generalizability (AUC=0.845). Dynamic profiles revealed peak PLR and SIRI at 6 hours post-admission. Multivariate analysis identified PLR and SIRI as independent risk factors for HLAP. CONCLUSIONS:PLR and SIRI are valuable, easily accessible tools for early HLAP diagnosis. Their high diagnostic accuracy, particularly when combined with TG, provides a robust method for prompt identification and targeted therapy.
Background: Qijiao Shengbai Capsule is a traditional multi-herb formulation composed of natural products including Jujube (Ziziphus jujuba), Donkey-hide gelatin (Colla corii asini), Pseudostellaria heterophylla, Epimedium brevicornum, Sophora flavescens, Astragalus membranaceus, and Angelica sinensis. These botanical and animal-derived ingredients are traditionally used to tonify Qi and blood, enhance immunity, and promote hematopoiesis. Purpose: This study aimed to evaluate the therapeutic efficacy and immunomodulatory effects of Qijiao Shengbai Capsule in combination with recombinant human granulocyte colony-stimulating factor (rhG-CSF) for the treatment of chemotherapy-induced leukopenia in patients with hematologic malignancies. Materials and Methods: A total of 90 patients with post-chemotherapy leukopenia were randomly assigned to receive either rhG-CSF alone or rhG-CSF combined with Qijiao Shengbai Capsule for 5 days. Key outcome measures included hematologic parameters, inflammatory cytokines (tumor necrosis factor alpha (TNF-alpha), interleukin (IL)-6, high-sensitivity C-reactive protein (hs-CRP)), immune function markers (CD3(+), CD4(+), NK cells), and adverse events. Results: The observation group demonstrated a significantly higher total effectiveness rate (93.33% vs. 75.56%, p < .001). Compared with rhG-CSF alone, the addition of Qijiao Shengbai Capsule significantly increased leukocyte, platelet, and hemoglobin levels, enhanced immune cell populations, and reduced pro-inflammatory cytokines (p < .01 for all). Adverse reaction rates were low and comparable between groups. Conclusion: Qijiao Shengbai Capsule, composed of bioactive natural ingredients, exhibits potent hematopoietic and immunomodulatory properties when combined with rhG-CSF over a 5-day treatment course, presenting a promising adjunctive treatment option for chemotherapy-induced leukopenia. These findings support the clinical and pharmacognostic relevance of this traditional herbal formulation in oncology care.
OBJECTIVE:Oxidative stress exerts an essential role in the pathogenesis of ulcerative colitis (UC). This study aims to unveil the heterogeneity in oxidative stress among immune cell subpopulations in UC. METHODS:Human colon epithelial cells were exposed to 100 ng/mL LPS to stimulate UC, which were administrated with antioxidants 500 mM butylated hydroxyanisole or 20 μM N-acetylcysteine. A single-cell atlas was constructed across UC, and heterogeneous cell subpopulations were evaluated at single-cell and bulk levels. RESULTS:Activation of oxidative stress and inflammatory response, enhanced migration capacity, and impaired tight junction were observed in LPS-induced UC cell models, which were ameliorated by antioxidants. Five cell types: plasma cells, T cells, myeloid cells, and B cells were clustered across UC and control gut biopsies, which were tightly interacted. Myeloid cells were sub-clustered into conventional dendritic cells, M1 macrophages, IL23R+ myeloid cells, mast cells, and follicular dendritic cells; T cells were sub-clustered into Th17, CD4+ naïve T cells, CD8+ cytotoxic T cells, CD4+ exhausted T cells, CD8+ memory T cells, Tregs, and Th1. The heterogeneous myeloid and T cells was confirmed at the single-cell and bulk levels. The activity of oxidative stress was heterogeneous among diverse myeloid cell or T cell subpopulations, with the strongest activity in M1 macrophages and CD4+ exhausted T cells, respectively. It was also found the specific transcriptional programs of M1 macrophages and CD8+ cytotoxic T cells. CONCLUSION:Overall, our findings unveil the heterogeneity in oxidative stress and transcriptional programs among diverse myeloid and T cell subpopulations in UC.
This prospective study evaluated the efficacy and safety of Paksun Combination in combination with lisdexamfetamine versus lisdexamfetamine monotherapy for the treatment of chemotherapy-induced leukopenia. A 12-month randomized controlled trial (January to December 2022) assigned 96 patients with leukopenia to two treatment groups by computer-generated block randomization. The intervention group (48 patients) received lisdexamfetamine (20 mg, TID) plus leucovorin (20 mL, TID), while the control group (48 patients) received lisdexamfetamine only. The primary outcomes included hematologic recovery parameters, TCM symptom improvement and immunologic indices. The combination therapy demonstrated significantly higher clinical response rates (93.75% vs 75.00%; χ²=15.507, P<0.001), with accelerated leukocyte recovery (5.46±0.41 vs 4.07±0.50×109/L; P<0.001) and neutrophil restoration (2.78±0.69 vs 2.17±0.73×109/L; P=0.025). Immunological improvements included increased IgG (20.81±2.77 vs 17.95±3.10 g/L; P<0.001) and IgM levels (1.59±0.30 vs 1.07±0.24 g/L; P<0.001). No significant difference in adverse events was observed between groups (10.42% vs 18.75%; P=0.247). The combination of Shengbai mixture and leucogen demonstrates significantly enhanced myeloprotective efficacy with safety profiles comparable to those of leucogen monotherapy, thereby underscoring its potential as a highly effective therapeutic modality.
Multi-classification of colorectal polyps using endoscopic images is crucial for enhancing clinical diagnostic accuracy and reducing colorectal cancer mortality. Accurately classifying colorectal polyps poses significant challenges due to blurred lesion boundaries, varying intra-class scales, and high inter-class similarities. To address these challenges, we propose the Fused Residual Attention Network (FRAN) for colorectal polyp classification. FRAN employs a dual-branch structure to emphasize both semantic and detailed information. The Residual Attention Learning mechanism enhances lesion region detection, while Global Dependent Self-Attention captures global context. Additionally, the Edge Feature Fusion module, combined with Semantic Alignment, mitigates semantic loss during upsampling and captures edge-detailed features. We evaluated FRA on a private four-class colorectal polyp dataset, the three-class public Kvasir dataset, the three-class public HyperKvasir dataset, and the four-class public PICCOLO dataset. The overall classification accuracies achieved are 85.73
Accurate abnormality classification in intestinal images is critical for the diagnosis and treatment of early-stage intestinal cancers, but remains challenging due to the large intra-lesion variability and high similarity between abnormal lesions and normal tissue. To solve the above problems, a multi-scale high and low feature fusion attention network is proposed to efficiently utilize the features extracted by the backbone network. First, a multi-scale feature extraction module is used to extract features, and then a detail capture attention module and a dense sampling fusion module are used to focus on and fuse the lesion information hidden in the superficial and deep layers. Finally, classification effect is obtained by fusing the lesion information. Experiments show that the method achieves 98% classification accuracy on the Kvasir dataset with three types of normal, polyp and ulcer. In addition, the classification accuracy in the private dataset reaches 97.52% and the experimental effect is better than other existing deep learning classification methods.
Objective: This study investigated the role of dexmedetomidine (DEX) in dextran sulfate sodium (DSS)-induced NCM460 cells. Material and Methods: The viability and apoptosis of NCM460 cells treated with DEX with or without DSS were detected by CCK-8 and terminal deoxynucleotidyl transferase (TdT) dUTP nick-end labeling (TUNEL) assay. The level of inflammatory factors and expression of inflammation-related proteins, tight junction proteins and Ras homolog gene family, member A/Rho-associated coiled-coil containing protein kinase (RhoA/ROCK) signaling-related proteins in NCM460 cells treated with DEX and/or U46619 (RhoA/ROCK agonist) and/or DSS were detected by the respective enzyme-linked immunosorbent assay (ELISA) kits and Western blot analysis. The permeability of NCM460 monolayers was examined with transepithelial electrical resistance (TEER) assay. Results: DEX had no effect on NCM460 cell viability. However, DEX improved the viability and barrier damage and suppressed the apoptosis and inflammation of DSS-induced NCM460 cells. Correspondingly, the expression of inflammation-related proteins was reduced and the expression of tight junction proteins was increased in DSS-induced NCM460 cells after treatment with DEX. In addition, RhoA/ROCK signaling was activated in NCM460 cells induced by DSS, which was suppressed by DEX. The protective effects of DEX on DSS-indued NCM460 cells were reversed by U46619. Conclusion: DEX improved viability and barrier damage while suppressed apoptosis and inflammation in DSS-indued NCM460 cells by inhibiting RhoA/ROCK signaling pathway.
Phosphatidylinositol and several other phospholipids were tested for their ability to influence the (Na++K+)-ATPase activity of the cortical synaptic membrane from rats at various levels of free Ca2+. Phosphatidylinositol, but not phosphatidylethanolamine, phosphatidylcholine nor phosphatidylserine, markedly inhibited this enzyme activity, when the free Ca2+ concentration in the incubation media was less than 2.5 × 10−6 M. This result suggests that phosphatidylinositol may play a role in the depolarization and/or the release of neurotransmitters or intracellular substances in the brain.
