Pancreatic cancer remains a highly lethal malignancy owing to the difficulty of early detection. In 2021, the Chinese Consensus on Early Screening and Surveillance for Pancreatic Cancer in High-risk Individuals was first established. However, the evidence landscape has evolved rapidly, necessitating an updated, evidence-based framework tailored to the Chinese healthcare context. This revised consensus aims to standardize the early screening and surveillance process for high-risk populations in China. A multidisciplinary expert panel comprising 53 specialists from 17 provincial-level regions systematically reviewed the literature using the GRADE (Grading of Recommendations Assessment, Development and Evaluation) methodology. A modified Delphi process was employed, with consensus predefined as ≥75% agreement. The panel formulated 26 evidence-based recommendations covering screening objectives, the definition of high-risk populations (hereditary susceptibility, new-onset diabetes, chronic pancreatitis, and pancreatic cystic neoplasms), age at screening initiation, surveillance intervals, imaging modalities (magnetic resonance imaging/magnetic resonance cholangiopancreatography, endoscopic ultrasound, computed tomography), surgical indications, and lifestyle modifications. Of these recommendations, 14 are strong and 12 are weak, supported by evidence levels ranging from A to D. Implementation of this consensus in clinical practice will help improve the early diagnosis of stage I pancreatic cancer and high-grade precursor lesions, thereby advancing standardized multidisciplinary care and ultimately improving patient outcomes in China.

Microbial resistance and oxidative stress are two significant health issues associated with chronic illnesses and therapy failures. The antioxidant and antibacterial properties of Euphorbia cuneata Vahl. aerial component extracts made with various polarity solvents were assessed in this work.

Disc diffusion and minimum inhibitory concentration (MIC) tests were used to evaluate the 1,1-diphenyl-2-picrylhydrazyl radical scavenging activity, total phenolic and flavonoid contents, and antimicrobial activity of n-hexane, toluene, ethanolic, and aqueous extracts against specific ESKAPE pathogens (Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, and Candida albicans). High-performance liquid chromatography and gas chromatography-mass spectrometry were used to further characterize the most active extract.

Compared to the aqueous (IC₅₀ = 51.61 µg/mL), toluene (IC₅₀ = 30.57 µg/mL), and n-hexane (IC₅₀ = 128.15 µg/mL) extracts, the ethanolic extract demonstrated the greatest 1,1-diphenyl-2-picrylhydrazyl radical scavenging activity (97.90 ± 0.8%; IC₅₀ = 28.52 µg/mL). Additionally, it has the highest levels of flavonoids (40.5 ± 1.5 mg luteolin equivalents/g) and phenolic (80.0 ± 0.2 mg gallic acid equivalents/g). While gas chromatography-mass spectrometry found methyl 12-hydroxy-9-octadecenoate (44.39%) as the main volatile molecule, high-performance liquid chromatography analysis identified caffeic acid, pyrogallol, rutin, and 7-hydroxyflavone as important ingredients. The ethanolic extract showed antifungal activity against C. albicans (MIC = 6.25 mg/mL) and moderate antibacterial activity with the lowest MIC values against S. aureus (450 µg/mL) and E. coli (500 µg/mL).

The ethanolic extract of Euphorbia cuneata demonstrated potent in vitro antioxidant activity and moderate antimicrobial effects, primarily attributable to its high phenolic and flavonoid content. These results support its potential as a natural source of bioactive compounds for further development.

Mitochondrial DNA (mtDNA) variability, especially heteroplasmy, is believed to affect cellular immunobiogenesis, particularly in monocytes in metabolic syndrome (MetS). This study aimed to identify associations of monocytic mtDNA variability with its phenotypic indices, including cytokine secretion and gene expression, and cardiometabolic parameters in patients with MetS.

The cross-sectional study recruited 87 adult participants, including 34 healthy blood donors (Control group), 21 obese patients (Obesity group), and 32 MetS patients (MetS group). Blood biochemistry tests were performed on venous blood samples, and monocytes (CD14+ cells) were isolated. Monocyte mtDNA was analyzed by next-generation sequencing to identify low (5–10%) and intermediate (10–95%) heteroplasmy, and homoplasmy (≥95%). Expression of genes related to mitochondrial biogenesis, mitochondrial uncoupling, oxidative stress system, and NF-κB signaling was assessed by quantitative real-time polymerase chain reaction. Monocytes cultured with and without lipopolysaccharide for 24 h were analyzed by enzyme-linked immunosorbent assay to assess the cytokine secretion stimulation index.

Monocyte mtDNA showed low variability, but alternative homoplasmies were significantly more common. Intermediate and low heteroplasmy from the protein-coding locus correlated with stenosis (r = 0.396; 95% confidence interval (CI) 0.067–0.647) and low-density lipoprotein levels (r = −0.258; 95% CI −0.45 – −0.043). Intermediate heteroplasmy from the rRNA locus correlated with blood insulin levels (r = −0.228; 95% CI −0.424 – −0.019). D-loop low heteroplasmy correlated with fasting blood glucose (r = 0.275; 95% CI 0.062–0.464). Homoplasmies were associated with creatinine, blood urea nitrogen, and alkaline phosphatase. Intermediate heteroplasmy in mtDNA was associated with the monocyte cytokine secretion stimulation index (R2 = 0.156, P = 0.003). However, there was no significant association between mtDNA variability and the expression of the various genes.

Monocyte mtDNA shows relatively low variability. Low and Intermediate heteroplasmy are associated with cardiometabolic parameters, and intermediate heteroplasmy is associated with the monocyte cytokine secretion stimulation index.

Liver fibrosis is a pivotal and reversible stage in the progression of chronic liver disease. However, the mechanisms underlying fibrosis reversal remain unclear, and effective diagnostic biomarkers are lacking in clinical practice. In this study, we aimed to elucidate the role and molecular mechanisms of glutathione S-transferase Mu 3 (GSTM3) in liver fibrosis reversal, and preliminarily determine whether GSTM3 can serve as a novel biomarker for liver fibrosis reversal.

Carbon tetrachloride-induced mouse models of liver fibrosis and spontaneous reversal were established. Proteomic analysis was used to identify proteins shared between liver tissue and serum that were continuously downregulated during fibrosis reversal. The expression of GSTM3 was evaluated in the livers of mice undergoing fibrosis reversal and in clinical samples from patients with liver fibrosis. Hepatic stellate cells (HSCs) were transfected with Gstm3-silencing RNA or an overexpression plasmid to assess the effects on fibrosis markers. RNA sequencing analyses were performed, and the underlying molecular mechanisms were investigated.

Proteomic analysis revealed significantly decreased GSTM3 levels in both hepatic tissue and serum in mice undergoing fibrosis reversal, and its expression was negatively correlated with the extent of reversal. GSTM3 levels were markedly increased in the hepatic tissue and serum of patients with liver fibrosis. GSTM3 expression was upregulated in transforming growth factor-β-stimulated HSCs. GSTM3 knockdown inhibited the expression of fibrosis markers, such as collagen type I α1 and tissue inhibitor of metalloproteinase 1, whereas its overexpression promoted their expression. Mechanistic studies indicated that GSTM3 knockdown activated peroxisome proliferator-activated receptor γ (PPARγ) signaling and downregulated its downstream targets, cluster of differentiation 36 and fatty acid-binding protein 4, thereby suppressing HSC activation.

GSTM3 knockdown promotes liver fibrosis reversal via PPARγ signaling-mediated inhibition of HSC activation. Therefore, GSTM3 is a promising therapeutic target and diagnostic biomarker for liver fibrosis.

The current criterion of biochemical response to ursodeoxycholic acid in primary biliary cholangitis is an alkaline phosphatase (ALP) level of ≤1.67 × the upper limit of normal (ULN) after 12 months of treatment. However, a proportion of patients who meet this parameter may still progress to liver decompensation. This study aimed to optimize the clinical management of primary biliary cholangitis by (1) establishing ALP normalization as a core treatment target, (2) identifying early intervention windows, and (3) developing risk stratification criteria.

This multicenter retrospective study included an internal cohort and an external validation cohort. We assessed the prognostic impact of ALP normalization with Kaplan-Meier and Cox regression. Sankey diagrams and segmented Poisson regression analysis mapped dynamic risk transitions to identify critical intervention windows. Predictive performance (sensitivity/specificity/positive predictive value/negative predictive value (NPV)) of Mayo, Paris II, and Toronto criteria for 12-month ALP normalization was compared.

Patients achieving ALP normalization showed significantly higher complication-free survival versus those with ALP 1.0–1.67 × ULN (89.8% vs. 79.8%; P = 0.016). Segmented Poisson regression identified significant change points at 3.73 and 5.5 months for high-to-medium and medium-to-low risk transitions, respectively. Failure to meet the Toronto criteria at month 3 predicted non-normalization with 95% NPV, whereas Paris II criteria at month 6 provided optimal specificity (73%) for identifying patients who failed to achieve ALP normalization.

ALP normalization significantly improves clinical outcomes. Two subgroups demonstrate low normalization probability and warrant early intervention: (1) patients with ALP ≥ 1.67 × ULN after 3 months and (2) those not meeting Paris II criteria by month 6.

Adeno-associated virus (AAV) vectors have favorable safety and durable transgene expression but are limited in oncology by insufficient tumor specificity and off-target expression. Tumor hypoxia and non-small cell lung cancer (NSCLC)-associated surface ligands offer complementary layers of biological selectivity for more precise gene delivery. This study proposes an NSCLC-directed, hypoxia-responsive AAV architecture that integrates MGS4-guided capsid targeting with dual hypoxia-responsive element (HRE)-gated promoters driving glutamine-modified C-X-C motif chemokine ligand 9-fragment crystallizable region fusion protein (Q-CXCL9-Fc) expression and baculoviral IAP repeat containing 5 (BIRC5)-linked mesothelin (MSLN) silencing. We conceptually designed an AAV vector that combines three layers of NSCLC selectivity: MGS4-guided capsid targeting, hypoxia-gated transcription, and tumor-active promoter control. The capsid displays the MGS4 peptide, isolated by phage display biopanning as a high-affinity ligand for the lung squamous cell carcinoma cell line HCC15 and later shown to internalize into a substantial fraction of NSCLC cell lines and bind a subset of human NSCLC biopsy samples, indicating activity across multiple NSCLC subtypes. The genome encodes Q-CXCL9-Fc under a 4× HRE-cytomegalovirus promoter to sustain C-X-C motif chemokine receptor 3-dependent T-cell recruitment and a miR-30-based short hairpin RNA targeting MSLN under a 4× HRE-BIRC5 promoter to inhibit tumor progression. This architecture is hypothesized to enrich AAV entry into NSCLC lesions via MGS4 while restricting Q-CXCL9-Fc secretion and MSLN silencing to hypoxic, BIRC5-active tumor regions, enabling synergistic enhancement of antitumor immunity and suppression of tumor-intrinsic pathways. The proposed multimodal, hypoxia-responsive AAV platform represents a conceptual precision oncology strategy that couples environmental sensing, tumor-specific transcription, and peptide-defined tropism within a single vector and could inform next-generation NSCLC-directed AAV systems.

The pathogenic role of MIR142 genetic abnormalities in the development of primary diffuse large B-cell lymphoma (DLBCL) of the central nervous system (CNS) is unexplored. The objective of this study was to investigate the frequency, spectrum, and functional significance of mutations in the MIR142 gene in primary CNS DLBCL.

Direct Sanger sequencing of the MIR142 gene was performed in tumor tissue from 35 patients with primary DLBCL of the CNS. In silico prediction of microRNA (miRNA)–target interactions, enrichment analysis of target gene ontologies, and prediction of the secondary structure and minimum free energy of the miRNA hairpin were performed.

The mutation frequency was 37.1% (95% confidence interval: 23.2–53.7%). The vast majority of the identified single-nucleotide variants were located outside the regions encoding mature miRNA chains. In silico analysis showed that the n.29A>G mutation located in the seed sequence of miR-142-5p resulted in a significant reduction in the number of potential targets and alterations to the interaction spectrum. All single-nucleotide variants identified in the study patients caused a change in minimum free energy and affected the shape and length of the hairpin stem of pri-miRNA. The results indicate the fragility of the pri-miR-142 hairpin.

The frequency of gene mutations in primary DLBCL of the CNS significantly exceeds that reported for systemic DLBCL.
