Background/Aims:
Liver transplantation (LT) following total hepatectomy is a life-saving treatment for hepatocellular carcinoma (HCC). The HCC recurrence after LT hinders the effectiveness of the procedure. The objective of this study is to develop a pre-operative risk stratification model based on a liquid biopsy.
Methods:
We conducted a comprehensive multi-omics study of 260 HCC patients from three centers, including clinical data, low-coverage whole-genome sequencing of cell-free DNA (cfDNA) from plasma, as well as whole-exome, single-nucleus RNA, and spatial transcriptomics from matched tumor and non-tumor tissues.
Results:
We identified cfDNA-derived copy number alteration (CNA) signatures associated with post-transplant recurrence. By integrating cfDNA-derived CNA profiles with single-cell transcriptomic data, we traced recurrence-associated cfDNA to a distinct subpopulation of malignant cells within the primary tumor. These cells were embedded in a pro-metastatic microenvironment of specialized endothelial subtypes and cancer-associated fibroblasts. Notably, most recurrence-associated lesions were detectable in cfDNA prior to liver transplantation (LT). Building on these insights, we developed the ZJU Criteria based on CNA fragments and tumor markers, a pre-LT risk prediction tool that integrates conventional clinical factors with cfDNA-derived CNA signatures, and validated it using internal and independent external cohorts.
Conclusion
Our findings suggest that post-transplant recurrence commonly originates from advanced subclones that emerge late during tumor evolution. The ZJU Criteria provides an accurate, non-invasive strategy that significantly improves pre-LT risk stratification and clinical decision-making for patients with HCC.

Investigative Magnetic Resonance Imaging 2026;30(1):47-55
Purpose:
To characterize the electromagnetic (EM) behavior of a monopole and dipole hybrid (MDH) antenna and evaluate its performance relative to monopole and dipole antennas for 10.5 tesla (T) magnetic resonance imaging (MRI) applications.
Materials and Methods:
Full-wave EM simulations were performed to model an inductor-shortened 20-cm dipole and an MDH antenna with asymmetric 9-cm and 12-cm poles. Single elements and 16-channel arrays were arranged on cylindrical formers (inner diameter 25 cm) around a tissue-mimicking phantom (εr = 49, σ = 0.6 S/m, diameter = 18 cm, height = 30 cm) with ~4 cm inter-element spacing and no additional decoupling circuitry. The eight-channel monopole antenna and MDH arrays were further modeled and analyzed with and without coaxial feed cables to assess cable-induced effects on magnetic (B) field distribution. Relative individual transmit field maps of the 8-channel monopole antenna and MDH arrays were acquired on a 10.5 T MRI system using a gradient echo (GRE) sequence (repetition time [TR] = 4000 ms, echo time [TE] = 3.0 ms, acquisition time [TA] = 7:48 ms, flip angle = 60°, field of view [FOV] = 354 × 354 mm3 , resolution = 3.0 × 1.5 × 3.0 mm3 ).
Results:
The MDH antenna demonstrated enhanced longitudinal B-field concentration and improved directivity compared with the dipole antenna element. Across the 8- and 16-channel arrays, the MDH structures consistently exhibited lower coupling, reducing S 21 by up to 10 dB relative to the monopole and dipole antenna arrays. Cable attachment significantly altered the MDH field patterns, reflecting dipole-like sensitivity to commonmode currents; however, appropriate cable management preserved field stability.
Conclusion
The MDH antenna provides intrinsic decoupling advantages and robust multichannel behavior without requiring additional decoupling circuitry. These characteristics make the MDH architecture a strong candidate for next-generation high-density arrays for ultra-high field MRI.
3.Anti-Biofilm Effects of Alcohol-Free Mouthwash against Streptococcus mutans
Journal of Dental Hygiene Science 2026;26(1):10-19
Background:
Various commercial mouthwashes are used in Korea. However, comparative data on how alcohol-containing andalcohol-free formulations differ in their ability to inhibit Streptococcus mutans biofilm formation remain limited. Few studies have assessed both planktonic antimicrobial activity and antibiofilm efficacy under conditions that simulate clinical use. This study aimed to evaluate these effects by comparing alcohol-containing and alcohol-free mouthwashes in a single species, S. mutans.
Methods:
Four commercially available mouthwashes were tested: two cetylpyridinium chloride-based formulations (GarglinOriginalⓇ , Garglin ZeroⓇ ), two essential oil (EO)-based formulations, one alcohol-containing (Listerine Cool MintⓇ ), and one alcohol-free (Listerine Cool Mint MildⓇ [LM]). Sterile distilled water and 0.1% chlorhexidine (CHX) served as the negative and positive controls, respectively. The planktonic antimicrobial activity was evaluated after a 1-minute exposure. For the biofilm experiment, S. mutans biofilms were formed on hydroxyapatite discs for 16 hours and subsequently treated with each mouthwash three times per day for 1 minute, totaling six treatments during a 64-hour maturation period that simulated clinical rinsing. Biofilm viability (log CFU/ml), thickness, and live/dead cell ratios were assessed using culture-based methods and confocal laser scanning microscopy with COMSTAT software.
Results:
All commercial mouthwashes demonstrated complete bactericidal activity below the detection limit against planktonic S. mutans. In contrast, only LM and CHX showed significant antibiofilm activity. LM reduced biofilm colony-forming unit (CFU) by approximately 0.7 log and decreased biofilm thickness and live/dead ratios by 39.0% and 30.8%, respectively, compared with the control (p<0.01). CHX exhibited the greatest reduction across all parameters.
Conclusion
LM exhibited the strongest antibiofilm potential among all tested mouthwashes. These findings indicate thatalcohol-free EO rinses may be a clinically useful alternative for patients who cannot tolerate alcohol-containing products or long-term CHX use. Incorporating such formulations into daily oral hygiene routines may help prevent dental caries.

Objective To identify potential immunosenescence markers in benign prostatic hyperplasia(BPH)and to explore BPH-related senescent phenotypes. Methods Three transcriptome datasets and one single-cell RNA-sequencing(scRNA-seq)dataset for BPH and normal prostate tissues were obtained from the Gene Expression Omnibus(GEO)database. The GSE7307 and GSE119195 were combined to analyze differentially expressed genes(DEGs). Enrichment analysis and immune infiltration analysis were used to explore aging-related changes in the immune microenvironment. Weighted gene coexpression network analysis(WGCNA)was applied to identify immune-related genes in GSE132714. ScRNA-seq data were employed to investigate the transcriptomic landscape, luminal cell heterogeneity, and aging-related alterations in BPH through cell-cell communication and pseudotime analysis. Finally, the results were validated with in vitro experiments. Results A total of 1202 DEGs and 627 immune-related genes were identified in BPH and normal prostate tissues. Enrichment analysis indicated that the vascular endothelial growth factor(VEGF)signaling pathway exhibited a downregulated aging phenotype in BPH. In scRNA-seq analysis, 9 cell types were identified. The VEGF signaling pathway in BPH exhibited an aging-related expression pattern, characterized by decreased vascular endothelial growth factor A(VEGFA)in luminal cells. Conclusion Our study identified VEGFA as a marker of immunosenescence in BPH, with changes of the VEGF pathway. Meanwhile, low expression of VEGFA, coupled with high expression of placental growth factor(PlGF)and vascular endothelial growth factor receptor(VEGFR), represented a senescent phenotype of the prostate.

Objective To explore the efficacy of 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) in distinguishing the properties of abnormal lymph nodes and its role in assessing the prognosis of patients with related diseases, and to provide more precise evidence for clinical diagnosis and treatment regimen formulation. Methods The clinical data of 97 patients with malignant tumors diagnosed with abnormal lymph nodes at Wuxi People’s Hospital Affiliated to Nanjing Medical University between April 2024 and June 2025 were retrospectively analyzed. Patients were divided into a malignant lymph node group (n=47) and a benign lymph node group (n=50) based on pathological results. PET/CT metabolic parameters [maximum standardized uptake value (SUVmax), mean standardized uptake value (SUVmean), metabolic tumor volume (MTV), and total lesion glycolysis (TLG)] were compared between the two groups of patients. Receiver operating characteristic curves were used to evaluate the diagnostic value of 18F-FDG PET/CT parameters for abnormal lymph nodes. Progression-free survival was compared among patients in the malignant lymph node group stratified by different levels of SUVmax, SUVmean, MTV, and TLG. Results SUVmax, SUVmean, MTV, and TLG were significantly higher in the malignant lymph node group than in the benign lymph node group (P < 0.05). The areas under the receiver operating characteristic curves for predicting malignant lymph nodes with SUVmax, SUVmean, MTV, and TLG were 0.761, 0.855, 0.860, and 0.792, with sensitivities of 74.47%, 82.98%, 74.47%, and 70.21%, and specificities of 76.00%, 76.00%, 90.00%, and 82.00%, respectively (P < 0.05). Comparison of progression-free survival in patients with malignant lymph nodes with different 18F-FDG PET/CT parameter levels revealed that patients with lower levels of SUVmax, SUVmean, MTV, and TLG had significantly longer progression-free survival than those with higher levels (Log-rank χ2=4.297, P=0.038; Log-rank χ2=6.569, P=0.010; Log-rank χ2=5.970, P=0.015; and Log-rank χ2=7.422, P=0.006, respectively). Conclusion 18F-FDG PET/CT metabolic parameters (SUVmax, SUVmean, MTV, and TLG) demonstrate high efficacy in the differential diagnosis of benign and malignant abnormal lymph nodes and prognostic evaluation, providing significant guidance for clinical treatment decisions.

OBJECTIVE To investigate the effects of MIR149 rs2292832 and MIR499 rs3746444 gene polymorphisms on the efficacy of tofacitinib combined with iguratimod in the treatment of moderate‑to‑severe rheumatoid arthritis (RA), to provide genetic reference for individualized treatment of moderate‑to‑severe RA patients.METHODS This was a prospective cohort study, and patients were grouped according to genotyping results. A total of 320 patients with moderate-to-severe RA diagnosed in the department of immunology of our hospital between January 2023 and January 2024 were enrolled. All patients received standardized treatment with tofacitinib (5 mg twice daily) combined with iguratimod (25 mg twice daily) for 24 weeks treatment course. Clinical efficacy outcomes, including American College of Rheumatology (ACR) 20/50/70 responses, disease activity score‑28 based on C‑reactive protein (DAS28-CRP), erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP), were compared among patients with different genotypes. Combined-genotype analysis and multivariate Logistic regression analysis were also performed.RESULTS The MIR149 rs2292832 CC-genotype patients exhibited significantly higher ACR20, ACR50 and ACR70 response rates (88.90%, 67.78%, 45.56%) than those carrying CT- and TT-genotypes ( P <0.05). After 24 weeks treatment, the reductions in DAS28‑CRP, ESR and CRP were significantly greater in CC‑genotype patients than in CT‑ and TT‑genotype patients ( P <0.05), and the 24‑week DAS28‑CRP was significantly lower in the CC‑genotype patients than in CT‑ and TT‑genotype patients ( P <0.05). The MIR499 rs3746444 GG-genotype showed significantly higher ACR20, ACR50 and ACR70 response rates (91.46%, 73.17%, 52.44%) than those carrying AG‑ and AA‑genotypes ( P <0.05). After 24 weeks of treatment, the reductions in DAS28‑CRP, ESR and CRP were significantly greater in GG‑genotype patients than in AG- and AA-genotype patients and the 24‑weeks DAS28‑CRP was significantly lower in the GG‑genotype patients than in AG- and AA-genotype patients ( P <0.05). Among the nine combined‑genotyps, the CC+GG genotype yielded the best treatment response. The MIR149 rs2292832 CC and MIR499 rs3746444 GG genotypes were independent predictors of clinical remission ( P <0.01), whereas baseline DAS28‑CRP ≥ 6.5 served as a negative predictor of clinical remission ( P <0.05).CONCLUSIONS Gene polymorphisms of MIR149 rs2292832 and MIR499 rs3746444 significantly influence the therapeutic effect of tofacitinib combined with iguratimod in patients with moderate-to-severe RA. Patients carrying CC and GG genotypes achieve better treatment responses.

The drug resistance in the treatment of solid tumors is closely related to abnormalities in the tumor vascular microenvironment (TVM). The TVM is dynamically composed of multiple stromal, vascular, and immune cell populations together with extracellular matrix. Its structural disorder and functional imbalance can lead to abnormal angiogenesis, perfusion disorders, limited drug delivery, and insufficient immune cell infiltration, thereby creating a microenvironment conducive to tumor progression and treatment resistance. Therefore, the coordinated regulation of TVM through vascular normalization and immune remodeling has become an important research direction for improving the treatment effect of solid tumors. Tumor necrosis factor superfamily member 14 (TNFSF14), also known as LIGHT (homologous to lymphotoxin, inducible, competes with herpes simplex virus (HSV) glycoprotein D for herpesvirus entry mediator (HVEM), expressed by T lymphocyte), is an important molecule connecting tumor vascular remodeling and immune regulation. LIGHT can bind to the lymphotoxin β receptor (LTβR) to activate the NF-κB (nuclear factor kappa B)-related signaling pathway, regulate the functions of vascular endothelial cells and stromal cells, and induce the expression of adhesion molecules and chemokines such as VCAM-1(vascular cell adhesion molecule 1), ICAM-1(intercellular adhesion molecule 1), CCL19 (C-C motif chemokine ligand 19), CCL21 (C-C motif chemokine ligand 21), and CXCL13 (C-X-C motif chemokine ligand 13), promoting the formation of high endothelial venules (HEVs). HEVs can improve the vascular access of immune cells into tumor tissues and further promote the formation of tertiary lymphoid structures (TLS), providing a structural basis for the recruitment of effector T cells and sustained anti-tumor immune responses. At the same time, LIGHT interacts with HVEM to provide costimulatory signals to T cells, enhancing their activation, proliferation, and cytotoxic function. Thus, LIGHT can link tumor vascular normalization, immune cell recruitment, and T cell activation through the dual actions mediated by LTβR and HVEM, forming a coordinated regulation model of “vascular remodeling-immune infiltration-immune activation”, providing new molecular targets for the treatment of solid tumors. Despite LIGHT’s good anti-tumor potential, its therapeutic application is still limited by factors such as insufficient stability in vivo, short half-life, and potential off-target effects due to systemic exposure. In recent years, researchers have developed various strategies for the precise delivery of LIGHT, including fusion proteins, bacterial vectors, viral vectors, nanoparticles, chimeric antigen receptor T cells (CAR-T), and mesenchymal stem cells (MSCs), to enhance the enrichment, expression, or sustained release of LIGHT in tumor sites through different approaches, thereby improving its therapeutic efficacy and safety. This article systematically reviews the structural characteristics, biological functions, and molecular mechanisms mediating TVM remodeling by LIGHT, with a focus on the signal transduction mediated by LTβR and HVEM and their roles in tumor immune regulation. Subsequently, it systematically outlines the molecular mechanisms by which LIGHT regulates the tumor vascular microenvironment and its intrinsic connection with immune cell recruitment and activation, from the perspectives of TVM abnormalities, vascular normalization, HEV formation, and TLS induction. Furthermore, it categorizes and summarizes precise delivery strategies such as LIGHT fusion proteins, bacterial vectors, viral vectors, nanoparticles, CAR-T cells, and MSCs according to delivery vectors and modes of action, and compares their functional characteristics, antitumor effects, and potential advantages and limitations. On this basis, the article further discusses the key issues that LIGHT therapeutic strategies still face in terms of targeting, controllability,in vivo stability, safety, and clinical translation, and anticipates the potential value of its combination with immune checkpoint inhibitors, anti-angiogenic therapy, and other tumor treatment methods. This article aims to deepen the understanding of the antitumor mechanism of LIGHT from the perspective of synergistic regulation of tumor vascular microenvironment remodeling and immune activation, providing theoretical basis and new research ideas for the design of solid tumor treatment strategies based on precise regulation of TVM and the clinical translation of LIGHT-related treatment systems.
