Objective Orosomucoid1 (ORM1) is a novel target in the quest for anti-fatigue pharmacotherapy. Preliminary investigations have illuminated oleuropein (OLE) as a promising candidate molecule, poised to enhance ORM1 expression. To elucidate the influence of OLE on ORM1 protein expression and assess its ramifications on muscle endurance. Methods The impact of OLE on ORM1 protein expressions within hepatocytes and liver tissue was meticulously quantified through Western blotting; the effects of OLE on muscle endurance were evaluated via the rotarod and forced swimming tests; glycogen content within liver and muscle tissues was determined utilizing a specialized kit; and PAS staining was employed to visualize glycogen deposition in the gastrocnemius muscle. Results OLE demonstrated a capacity to elevate ORM1 protein expression in hepatocytes in a time- and dose-dependent manner, concurrently prolonging the duration of swimming and rotarod performance in mice, also in a time- and dose-dependent manner. Furthermore, OLE augmented ORM1 expression in liver tissue, elevated serum ORM1 levels, and enhanced glycogen reserves within the liver and muscle. Conclusion OLE may serve to amplify muscle endurance by elevating ORM1 levels in vivo and augmenting glycogen stores within skeletal muscle.

The inflammatory microenvironment is closely associated with the initiation and progression of osteoarthritis (OA), specifically manifesting as macrophage activation, dysregulation of inflammatory cytokines, and redox imbalance. Following an overview of the pathological characteristics of the OA inflammatory microenvironment, this paper reviews the research progress on the mechanism of traditional Chinese medicine (TCM) intervening in OA by modulating the inflammatory microenvironment. It has been found that TCM monomers/active ingredients (such as total alkaloids from Strychnos nux-vomica , quercetin, triptolide, etc.), herb pairs (e.g. Angelica pubescens - Gentiana macrophylla , Carthami Flos-Lycopodii Herba), and TCM formulas (such as Zhuanggu jianxi formula, Duhuo jisheng decoction and Rongjin niantong formula, etc.) can inhibit macrophage activation, reduce the release of proinflammatory cytokines and the generation of reactive oxygen species by inhibiting multiple signaling pathways, including nuclear factor-κB, Wnt/ β -catenin, and mitogen-activated protein kinase, thereby alleviating the articular inflammatory microenvironment, restoring local joint homeostasis, and slowing the progression of OA.

ObjectiveTo explore the function and related molecular mechanisms of magnoflorine against colon cancer via network pharmacology, molecular docking, and in vitro cell experiments. MethodsIn this study, the canonical SMILES of magnoflorine was obtained from the PubChem database, and the potential targets of magnoflorine were predicted by the Swiss Target Prediction database, while the disease targets of colon cancer were obtained from the DisGeNET, GeneCards and OMIM databases. The intersecting targets between magnoflorine's predicted targets and colon cancer disease targets were taken, and a protein-protein interaction (PPI) network was constructed and analyzed. The DAVID online database was employed to conduct Gene Ontology (GO) and KEGG pathway enrichment analyses on core targets. The top five key targets screened were docked with magnoflorine using AutoDock software. Finally, cellular experiments including CCK-8 assays, EdU experiments, cell scratch assays, and Transwell assays were conducted to validate the results from network pharmacology and molecular docking. Results44 key targets of magnoflorine in resisting colon cancer were acquired. The molecular docking results showed that magnoflorine had a strong binding activity with the core target signal transducer and activator of transcription 3 (STAT3) in the top five of the PPI network. Cellular experiments confirmed that magnoflorine could inhibit the proliferation and migration of colon cancer cells by suppressing the JAK/STAT3 signaling pathway. ConclusionMagnoflorine may inhibit the proliferation and migration of colon cancer cells by regulating the JAK/STAT3 signaling pathway.

The internal structures of cells as the basic units of life are a major wonder of the microscopic world. Cellular images provide an intriguing window to help explore and understand the composition and function of these structures. Scientific imagery combined with artistic expression can further expand the potential of imaging in educational dissemination and interdisciplinary applications. This study presents an innovative diffusion model-based approach for style transfer in cellular images, combining scientific rigor with artistic expression. By leveraging training-free large-scale pre-trained diffusion models, the proposed method integrates the intricate morphological and textural features of cellular images with diverse artistic styles. Key techniques such as the inversion of denoising diffusion implicit models (DDIMs), adaptive instance normalization (AdaIN), self-attention style injection, and attention temperature scaling ensure the preservation of cellular structures while enhancing visual expressiveness. The results showcase the potential of this strategy for interdisciplinary applications, enriching both the visualization and educational dissemination of cellular imagery through compelling storytelling and aesthetic appeal.

Myelin is an essential structure that facilitates rapid saltatory conduction in the nervous system. Discrepancies in myelin microstructure are a hallmark of numerous neurological disorders, rendering the assessment of myelin integrity and content an indispensable tool in clinical diagnostics and neuroscience research. Extensive research has been dedicated to scrutinizing its biochemical makeup and morphology under normal, pathological, and experimental conditions over the years. In this review, we present an updated summary of the myelin sheath's structure, composition, and developmental trajectory. We systematically enumerate and contrast eight prevalent myelin staining techniques across dimensions of sensitivity, specificity, and resolution, delving into their underlying staining principles. With an initial application of myelin histology on the mouse demyelination model, our review accentuates the accurate delineation of myelination and the microstructural analysis of the myelin sheath. Such insights are anticipated to significantly contribute to the evaluation and understanding of white matter pathologies.

Glioma, the most prevalent primary tumor of the central nervous system (CNS), is also the most lethal primary malignant tumor. Currently, there are limited chemotherapeutics available for glioma treatment, necessitating further research to identify and develop new chemotherapeutic agents. A significant approach to discovering anti-glioma drugs involves isolating antitumor active ingredients from natural products (NPs) and optimizing their structures. Additionally, targeted drug delivery systems (TDDSs) are employed to enhance drug solubility and stability and overcome the blood-brain barrier (BBB). TDDSs can penetrate deep into the brain, increase drug concentration and retention time in the CNS, and improve the targeting efficiency of NPs, thereby reducing adverse effects and enhancing anti-glioma efficacy. This paper reviews the research progress of anti-glioma activities of NPs, including alkaloids, polyphenols, flavonoids, terpenoids, saponins, quinones, and their synthetic derivatives over the past decade. The review also summarizes anti-glioma mechanisms, such as suppression of related protein expression, regulation of reactive oxygen species (ROS) levels, control of apoptosis signaling pathways, reduction of matrix metalloproteinases (MMPs) expression, blocking of vascular endothelial growth factor (VEGF), and reversal of immunosuppression. Furthermore, the functions and advantages of NP-based TDDSs in anti-glioma therapy are examined. The key information presented in this review will be valuable for the research and development of NP-based anti-glioma drugs and related TDDSs.

(+)-Strebloside, a significant bioactive compound isolated from the roots of Streblus asper Lour., demonstrates inhibitory effects against multiple malignancies. However, its specific function and underlying mechanistic pathways in Non-Hodgkin lymphoma (NHL) remain unexplored. This investigation sought to elucidate the role and potential mechanisms of (+)-strebloside-induced NHL cell death. The results demonstrated that (+)-strebloside significantly induced apoptosis and ferroptosis in NHL cells, including those from Raji cell-derived xenograft models. Mechanistic analyses revealed that (+)-strebloside enhanced six-transmembrane epithelial antigen of prostate 3 (STEAP3)-induced ferroptosis in NHL, and STEAP3 inhibition reduced the proliferation-inhibitory effects of (+)-strebloside. Furthermore, (+)-strebloside suppressed NHL proliferation through the mitogen-activated protein kinase (MAPK) pathway, and extracellular signal-regulated kinase (ERK) inhibition diminished the proliferation-inhibitory activity induced by (+)-strebloside. These findings indicate that (+)-strebloside presents promising therapeutic potential for NHL treatment.

Objective:To investigate the effects of pulsed electric field (PEF) combined with gemcitabine (GEM) on the viability and stemness of HCCC-9810 cholangiocarcinoma stem cells.Methods:HCCC-9810 cholangiocarcinoma stem cells were established in serum-free, cytokine-rich medium and divided into four groups: the control group, GEM group, PEF group, and the pulsed electric field combined with gemcitabine (PEF+ GEM) group. Cell proliferation was detected using the Cell Counting Kit-8 (CCK8) assay. Cell viability and apoptosis rate were measured by flow cytometry. Cell invasion ability was assessed using the Transwell assay. The expression of stemness marker proteins CD133 and Octamer-binding transcription factor 4 (OCT4), as well as the expression of β-catenin, was detected by Western blotting.Results:Regarding cell viability, the GEM, PEF, and PEF+ GEM groups showed significantly lower cell viability and higher apoptosis rate than the control group at 24 h, 48 h, and 72 h (all P<0.05). At 48 h and 72 h, the PEF+ GEM group showed significantly lower cell viability (7.2%±0.3% and 5.9%±0.8%, respectively) than the GEM group (50.7%±0.6% and 31.0%±1.2%, respectively) and the PEF group (12.2%±0.2% and 12.8%±0.2%, respectively) (all P<0.05). Regarding stemness inhibition, the PEF+ GEM groups showed significantly lower expression levels of CD133 and OCT4 at 24 h, 48 h, and 72 h compared with the control group (all P<0.05). Notably, at 48 h, the PEF+ GEM group showed a significantly lower expression level of the OCT4 (0.61±0.02) than the GEM group (0.87±0.08) and the PEF group (1.00±0.10) ( P<0.01). Furthermore, at 24 h and 48 h, the GEM, PEF, and PEF+ GEM groups showed significantly lower expression levels of β-catenin compared with the control group (all P<0.05). Conclusion:Pulsed electric field combined with gemcitabine therapy demonstrated more effective anti-proliferation and cancer stemness inhibition effects on HCCC-9810 cholangiocarcinoma stem cells compared with either monotherapy.

Objective:To explore the efficacy and safety of negative-pressure wound therapy (NPWT) in treating infected wounds in orthopedic trauma patients.Methods:China National Knowledge Infrastructure, China Biomedical Literature Database, Wanfang Data Knowledge Service Platform, PubMed, Web of Science, Cochrane Library, and CINAHL were searched for randomized controlled trials (RCT) and cohort studies examining the impact of NPWT on wound healing in orthopedic trauma infections. The retrieval time was from the establishment of the databases to October 2024. RevMan 5.4 software was used for Meta-analysis. The patients were divided into two groups according to different treatment methods: the intervention group, treated with NPWT, and the control group, treated with conventional treatment. The observed indicators included clinical efficacy, wound healing quality, length of hospital stay, wound healing time, incidence of complications, secondary surgery rate, and duration of antibiotic use. Publication bias analysis was performed on the observed indicators through Begg and Egger tests.Results:A total of 13 studies were included, comprising 11 RCT and 2 cohort studies, involving a total of 3 538 patients, with 1 762 in the intervention group and 1 776 in the control group. The meta-analysis results indicated that the intervention group had better clinical efficacy ( OR=7.08, 95% CI 5.31, 9.45, P<0.01), higher wound healing quality ( MD=4.15, 95% CI 3.99, 4.32, P<0.01), shorter length of hospital stay ( MD=-13.38, 95% CI -14.39, -12.38, P<0.01), shorter wound healing time ( MD=-8.11, 95% CI -10.22, -6.00, P<0.01), lower incidence of complications, lower secondary surgery rate ( OR=0.22, 95% CI 0.09, 0.57, P<0.01), and shorter duration of antibiotic use ( MD=-7.61, 95% CI -8.06, -7.16, P<0.01) when compared with the control group. No significant publication bias was observed in the aforementioned indicators ( P>0.05). Conclusion:Compared with the conventional treatment, NPWT can enhance the clinical efficacy and wound healing quality of infected wounds in orthopedic trauma patients, shorten length of hospital stay and wound healing time, reduce the incidence of complications and secondary surgery rates, and shorten the duration of antibiotic use.

Objective To explore the factors predicting the reliability of platelet-impedance(PLT-I)re-sults through a retrospective analysis of non-aggregated samples with abnormal platelet histograms.Methods A total of 322 samples with abnormal platelet histograms were collected from the Sysmex XN9000 automatic hematology analyzer,all of which showed no platelet aggregation as determined by the DI-60 auto-matic digital image analysis system.Using the platelet count fluorescent(PLT-F)results as a standard,the absolute and relative deviations of PLT-I results were calculated,and the parameters of samples with devia-tions within and outside the allowable range were analyzed.Logistic regression analysis was used to identify potential factors associated with deviations of PLT-I from PLT-F beyond the allowable range.The receiver op-erating characteristic(ROC)curve was used to evaluate the predictive value of these potential factors for devi-ations beyond the allowable range.Results The deviations of PLT-I from PLT-F were within the allowable range in 279 cases(86.65%)and outside the allowable range in 43 cases(13.35%).Comparisons between the two groups revealed statistically significant differences in mean red blood cell valume(MCV),red blood cell distribution width-cuefficient of variation(RDW-SD),DI-60 red cell fragments,platelet distribution width(PDW),and DI-60 large platelet ratio(P<0.05).Logistic regression indicated that DI-60 red cell fragments and DI-60 large platelet ratio were independent potential factors for deviations of PLT-I from PLT-F beyond the allowable range(P<0.05).The cut off values for predicting deviations beyond the allowable range were 1.75 for DI-60 red cell fragments and 66%for DI-60 large platelet ratio.The area under the curve(AUC)for the combined diagnosis of the two factors was 0.813,with a sensitivity of 88.4%and a specificity of 66.3%,indicating a higher predictive value than individual factors(P<0.05).Conclusion When platelet histograms are abnormal,DI-60 large platelet ratio and DI-60 red cell fragments are independent potential factors predic-ting the reliability of PLT-I results,and their combination has a high predictive value.
