Objective To elucidate the mechanism by which the BANCR/miR-145-5p axis regulates the AKT-GLUT1/HK2 pathway through downstream targets Reg3A/DMBT1 to facilitate the Warburg effect in gastric cancer. Methods Expression levels of BANCR, miR-145-5p, Reg3A, and DMBT1 were detected by RT-qPCR and Western blot in gastric cancer tissues and cell lines. Dual-luciferase reporter assays confirmed targeted relationships. Glycolytic capacity was assessed via glucose uptake. Immunohistochemistry analyzed molecular expression in 60 paired clinical samples. The prognostic values of key molecules in the BANCR/miR-145-5p-Reg3A/DMBT1 axis were evaluated by Kaplan-Meier survival analysis and Cox proportional hazards regression model. Results BANCR was significantly upregulated, whereas miR-145-5p was downregulated in gastric cancer tissues, correlating with advanced TNM stage, lymph node metastasis, and poor differentiation. Reg3A and DMBT1 were identified as direct targets of miR-145-5p. Knockdown of BANCR or overexpression of miR-145-5p significantly suppressed Reg3A/DMBT1 expression, reduced AKT phosphorylation and GLUT1/HK2 levels, and inhibited glycolysis. Clinical analysis revealed positive correlations between Reg3A/DMBT1 expression and glycolytic markers, with both serving as independent risk factors for poor prognosis. Conclusion The BANCR/miR-145-5p axis activates the AKT pathway by targeting Reg3A/DMBT1, thereby promoting GLUT1/HK2/LDHA-mediated glycolysis and facilitating the Warburg effect in gastric cancer. This regulatory axis represents a potential therapeutic target and prognostic biomarker.

Ductular reaction （DR） refers to the adaptive pathological changes that occur after hepatobiliary injury， and it is essentially a repair response involving the proliferation， fibrosis， and inflammation of biliary epithelial cell （BEC）. With the understanding of the biological function of BEC， the potential value of DR in disease prognosis and treatment has gradually become a research hotspot. This article systematically reviews the molecular mechanism of DR， its potential as a therapeutic target， and future development directions， as well as novel therapies suggested by targeting these molecular mechanisms， in order to provide a new direction for overcoming current bottlenecks in the treatment of bile duct diseases.

Background/Aims: Acetyl coenzyme A (acetyl-CoA) is one of the most essential metabolites in cell metabolism but its function and concentration in hepatocellular carcinoma (HCC) remain elusive and controversial. Methods: A comprehensive analysis of acetyl-CoA levels and acetyl-CoA synthetase 2 (ACSS2) expression across a range of samples, including patient specimens from both hepatitis B virus (HBV) positive and HBV negative HCC individuals, HBV-transgenic mouse HCC models, and multiple cell lines. Furthermore, to evaluate the functional significance of ACSS2 in HBV-related HCC, we implemented both genetic and pharmacological inhibition strategies targeting ACSS2. Molecular mechanism and mitophagy assessment were revealed by cleavage under target and tagmentation sequencing, RNA sequencing, bioinformatic analyses, transmission electron microscopy and JC-1 staining. Results: Our study revealed a distinct metabolic signature of HBV-related HCC, marked by elevated acetyl-CoA, which was driven by ACSS2. ACSS2 was upregulated by the carbohydrate response element-binding protein in HBV-related HCC. Furthermore, ACSS2 improved tumor cell proliferation, an effect that was dependent on its enzymatic activity. Mechanistically, ACSS2-induced acetyl-CoA accumulation activated voltage-dependent anion channels 1 transcription through increased H3K27ac occupancy, which subsequently promoted mitophagy and HBV-related HCC tumorigenesis. Notably, targeting ACSS2 by depletion or inhibition with a catalytic inhibitor significantly suppressed tumor growth. Conclusions These findings not only illustrate the interplay between metabolic reprogramming, epigenetic modification, and tumorigenesis in the context of HBV infection, but also highlight ACSS2 as a novel metabolic vulnerability in HBV-related HCC. Therefore, targeting ACSS2 could be a novel strategy against HBV-related HCC.

Background: and Purpose Symptomatic intracranial hemorrhage (sICH) following endovascular thrombectomy (EVT) is a severe complication associated with adverse functional outcomes and increased mortality rates. Currently, a reliable predictive model for sICH risk after EVT is lacking. Methods: This study used data from patients aged ≥20 years who underwent EVT for anterior circulation stroke from the nationwide Taiwan Registry of Endovascular Thrombectomy for Acute Ischemic Stroke (TREAT-AIS). A predictive model including factors associated with an increased risk of sICH after EVT was developed to differentiate between patients with and without sICH. This model was compared existing predictive models using nationwide registry data to evaluate its relative performance. Results: Of the 2,507 identified patients, 158 developed sICH after EVT. Factors such as diastolic blood pressure, Alberta Stroke Program Early CT Score, platelet count, glucose level, collateral score, and successful reperfusion were associated with the risk of sICH after EVT. The TREAT-AIS score demonstrated acceptable predictive accuracy (area under the curve [AUC]=0.694), with higher scores being associated with an increased risk of sICH (odds ratio=2.01 per score increase, 95% confidence interval=1.64–2.45, P<0.001). The discriminatory capacity of the score was similar in patients with symptom onset beyond 6 hours (AUC=0.705). Compared to existing models, the TREAT-AIS score consistently exhibited superior predictive accuracy, although this difference was marginal. Conclusions The TREAT-AIS score outperformed existing models, and demonstrated an acceptable discriminatory capacity for distinguishing patients according to sICH risk levels. However, the differences between models were only marginal. Further research incorporating periprocedural and postprocedural factors is required to improve the predictive accuracy.

Objective: To assess the effect of transarterial embolization (TAE) for adhesive capsulitis (AC) by evaluating clinical outcomes and changes in inflammation using magnetic resonance imaging (MRI). Materials and Methods: Patients who had undergone TAE between August 2020 and August 2023 for AC refractory to conservative treatments without any invasive procedures for more than 3 months, and had undergone baseline and 3-month post-AC follow-up contrast-enhanced MRI evaluations, were included. A suspension mixture of 500 mg imipenem/cilastatin in 10 mL of iodinated contrast agent was used for TAE. MRI results were analyzed to assess periarticular capsule/ligament inflammation. Clinical assessments included pain scores using the numeric rating scale (NRS) and functional scores using the quick disabilities of the arm, shoulder, and hand (Quick DASH) questionnaire. Results: Twenty-five patients (female:male, 14:11; age, 54.9 ± 7.1 years) were included. Significant reductions in average NRS pain scores as well as improvements in Quick DASH scores and range of motion, including anterior flexion and abduction, were observed at 1, 3, and 6 months after TAE (all P < 0.001). MRI analyses revealed that TAE significantly decreased the grades of axillary recess capsule enhancement, rotator interval (RI) capsule T2 signal intensity, and RI capsule enhancement (all P ≤ 0.004). Conclusion TAE may be an effective and safe therapeutic approach for AC refractory to conservative treatments, alleviating pain and supporting functional recovery. The observed MRI findings suggest that the effectiveness of TAE for AC may be attributed to the reduction of inflammation and the elimination of angiogenesis.

Metabolic reprogramming is a crucial feature of cancer.Among various metabolic processes,oxidative phosphorylation(OXPHOS)metabolism serves as the primary biochemical pathway for energy production and significantly influences tumorigenesis and tumor development.Therefore,this study aims to explore the impact of the metabolic characteristics of lung squamous cell carcinoma(LUSC)on its ma-lignant properties.By analyzing the single-cell transcriptome sequencing data of LUSC,lung adenocarci-noma,and normal lung tissues from the gene expression profile database,it was found that the OXPHOS signaling pathway and molecules related to ATP synthesis were remarkably enriched in LUSC tissues.Based on the OXPHOS signal intensity score,LUSC cells were classified into OXPHOShigh and OXPH-OSlow groups.Bioinformatics analysis revealed that 126 transcription factors were highly expressed in both LUSC tumor tissues and the OXPHOShigh group.Notably,the expression levels of cancer stem cell-related signals(such as SOX2,SOX9,POU2F1,CDX1,ARID3A,EZH2,and KLF5)were significantly en-hanced in the OXPHOShigh cell subset(P＜0.05).Treatment of LUSC cells with an OXPHOS antagonist significantly inhibited the sphere formation rate of H520 and SKMES-1 cells,which is a key characteristic of cancer stemness(P＜0.05).Analysis of cell-cell communication data from the LUSC single-cell tran-scriptome indicated that the signal emission and reception in OXPHOShigh cells were stronger than those in OXPHOSlow cells.Moreover,fibroblasts showed significant interaction with OXPHOShigh-LUSC cells.Co-culture of LUSC cell lines H520 and SKMES-1 with human lung fibroblast-like cell lines significantly in-creased the sphere formation rate of tumor cells(P＜0.05).Additionally,the levels of ATP,NADH-ac-tive enzymes,and reactive oxygen species(ROS)in co-cultured H520 and SKMES-1 cells were signifi-cantly elevated(P＜0.05).The results of this study confirm that the OXPHOS pathway is a key signal involved in LUSC metabolism,which is closely associated with the characteristics of cancer stem cells and the regulatory signals of fibroblast interactions.This finding holds promises for providing novel strategies for tumor treatment.

Objective To investigate the association of endometrial thickness(EMT)with obstetric and neonatal outcomes of monoparous pregnancy in fresh cleavage embryos transfer.Methods A total of 1 845 patients of monoparous pregnancy after fresh cleavage embryos transfer cycles from Jan 2016 to Mar 2022 at Shanghai First Maternity and Infant Hospital,Tongji Universtiy were analyzed retrospectively.Patients were categorized into three groups by EMT on transferation day:≤8 mm(group A),8-14 mm(group B)and≥14 mm(group C).The primary outcomes were preterm birth(PTB),birth weight and birth weight z-score,small-for-gestation age,large-for-gestation age,very low birth weight,low birth weight and macrosomia.The second outcomes were pregnancy and perinatal complications.The relationship between EMT and adverse neonatal outcomes was estimated by Logistic regression analysis.Results The rate of ectopic pregnancy was increased significantly in group A.No significant differences were found among the three groups in gestation age,birth weight,birth weight z-score,PTB,small for gestation age,large for gestation age,low birth weight,very low birth weight and macrosomia.Compared with group B,the odds of adverse neonatal outcomes did not show significant differences before and after adjustment in both group A and group C by Logistic regression analysis.Conclusion Thinner EMT in fresh cleavage embryos transfer is associated with higher rate of ectopic pregnancy,while it is not independently associated with adverse perinatal outcomes.

Aim To investigate the central mechanism by which dexmedetomidine(DEX)alleviated pain sensitization and anxiety-like behaviors in mice caused by nicotine withdrawal stress.Methods A mouse model of nicotine withdrawal was established,and DEX was administered to detect its effects on the behaviors of nicotine-withdrawn mice.The von Frey mechanical pain test was used to measure the pain threshold of mice,and the open-field test was used to detect the anxiety-like behaviors of mice.Immunofluorescence staining was performed to detect the changes in neurons in the anterior cingulate cortex(ACC)and locus coer-uleus(LC)brain regions of nicotine-withdrawn mice.Anterograde and retrograde tracing viruses were used to detect the projection connection between LC and ACC.Chemogenetic methods were used to regulate the activi-ty of LC neurons.Fiber photometry was used to detect the release of norepinephrine and the activity of neu-rons in the ACC.Results Nicotine-withdrawn mice exhibited pain sensitization and anxiety-like behaviors.The activities of neurons in the LC and ACC of nico-tine-withdrawn mice increased.A functional projection connection was found in the LC-ACC neural circuit.Activating the LC-ACC neural circuit induced pain hy-persensitivity and anxiety-like behaviors in mice.DEX alleviated the pain hypersensitivity and anxiety-like be-haviors caused by nicotine withdrawal through the LC-ACC neural circuit.Conclusion DEX acts on the LC-ACC neural circuit,inhibits the release of norepi-nephrine and the activity of neurons in the ACC,and alleviates the pain sensitization and anxiety-like behav-iors induced by nicotine withdrawal.
