ObjectiveTo investigate the efficacy of selective internal radiation therapy （SIRT） in patients with unresectable hepatocellular carcinoma， and to provide a reference for the selection of clinical treatment regimens. MethodsA retrospective analysis was performed for the clinical data of 73 patients with unresectable hepatocellular carcinoma who received yttrium-90 microsphere SIRT in Eastern Hepatobiliary Surgery Hospital from May 1， 2023 to September 1， 2024. According to tumor characteristics， physical status， liver reserve function， laboratory tests， and SIRT treatment strategy， the patients were divided into radiation segmentectomy group with 9 patients， conversion therapy group with 47 patients， and palliative treatment group with 17 patients. Based on the results of postoperative follow-up， modified Response Evaluation Criteria in Solid Tumors were used to assess radiographic images. A one-way analysis of variance was used for comparison of normally distributed continuous data between three groups， and the chi-square test was used for comparison of categorical data between three groups； the Logistic regression model was used to perform the multivariate analysis. ResultsThere was a significant difference in postoperative outcome between the radiation segmentectomy group， the conversion therapy group， and the palliative treatment group （χ²=30.060， P<0.001）. The disease control rate was 100.0% （9/9） in the radiation segmentectomy group， 83.0% （39/47） in the conversion therapy group， and 29.4% （5/17） in the palliative treatment group， with a significant difference between the three groups （χ²=19.575， P<0.001）， and there was also a significant difference in objective response rate between the three groups （χ²=17.749， P<0.001）. The multivariate Logistic regression analysis showed that the number of tumors （odds ratio ［OR］=0.085， 95% confidence interval ［CI］： 0.008 — 0.906， P=0.041） and combined targeted immunotherapy （OR=18.808， 95%CI： 1.704 — 207.616， P=0.017） were independent influencing factors for achieving complete response. ConclusionThe number of tumors is an independent influencing factor for the efficacy of SIRT and is an important basis for selecting different treatment goals. SIRT combined with targeted immunotherapy may achieve better efficacy.

Metabolic associated fatty liver disease （MAFLD） has become one of the most prevalent chronic liver disease worldwide， and its progression to liver fibrosis is a key influencing factor for prognosis and the risk of complications. In recent years， novel drugs， such as selective thyroid hormone receptor-β agonists， glucagon-like peptide-1 receptor agonists， and fibroblast growth factor 21 analogs， have shown preliminary efficacy in the treatment of MAFLD-related liver fibrosis； however， such drugs have limited overall effectiveness， and there is still a lack of ideal therapeutic strategy to address the disease across its different stages. Traditional Chinese medicine （TCM）， with its characteristics of multiple targets and systemic regulation， has shown unique advantages in this field. This article systematically reviews the basic and clinical research on the anti-fibrotic mechanisms of compound TCM prescriptions and their active components in recent years， focusing on the key processes including hepatic stellate cell activation， lipid metabolism disorders， oxidative stress， immune inflammation， and gut-liver axis dysfunction. Meanwhile， it is pointed out that there are still certain issues in current research， including ambiguities in the clarification of mechanisms， a lack of standardized evaluation systems， and the need to improve the quality of clinical evidence. Future research should emphasize the standardization and quality control of TCM herbal preparations and integrate emerging technologies， such as omics analysis， organoid models， and real-world data， to advance TCM intervention of MAFLD-related liver fibrosis toward well-defined mechanisms， clear therapeutic pathways， and robust scientific evidence. TCM is expected to play a vital role in the multi-dimensional targeted intervention and stage-specific management of MAFLD-related liver fibrosis， in order to provide new perspectives and comprehensive solutions for the precise treatment of chronic liver diseases.

Objective:To explore the differences of metabolomic profiles in day 3 (D3) culture medium of embryos with varying developmental potentials, in order to provide a theoretical foundation for the establishment of embryo selection technology platform using metabolomics.Methods:Eight patients who received in vitro fertilization and embryo transfer (IVF-ET) treatment at Reproductive Medicine Center of Guangxi Zhuang Autonomous Region Maternal and Child Health Hospital between November 13 and December 5, 2023 were selected as the study subjects. The D3 culture medium from patient embryos was collected and divided into high-quality blastocysts ( n=42), non-high-quality blastocysts ( n=33), and embryos that failed to form blastocysts (non-formation group, n=43) according to the formation of day 5 blastocysts. High-performance liquid chromatography-mass spectrometry was employed to perform non-targeted metabolomic analysis in the D3 culture medium from three distinct groups. Results:1) The metabolites in D3 culture medium of embryos with varying developmental potentials exhibit significant differences. Specifically, 79 differential metabolites were identified between the blastocyst formation group and the non-blastocyst formation group (all P<0.05); additionally, 73 differential metabolites were found between the high-quality blastocyst group and the non-high-quality blastocyst group (all P<0.05). 2) The area under the receiver operating characteristic curve of significantly differential metabolites for predicting potential of D3 embryo blastocyst formation and high-quality blastocyst formation were both greater than 0.9, demonstrating excellent predictive performance. 3) KEGG pathway enrichment analysis revealed that differential metabolites associated with blastocyst formation potential were primarily enriched in pathways including D-amino acid metabolism, glycine-serine-threonine metabolism, arginine biosynthesis, and histidine metabolism ( P<0.05). For high-quality blastocyst formation, the differential metabolites were predominantly enriched in pathways related to tryptophan metabolism, D-amino acid metabolism, serotonergic synapses, and protein digestion and absorption ( P<0.05). Conclusion:Embryos with different developmental potentials have significantly different metabolic profiles, and it is feasible to predict the developmental potential of D3 embryos by metabolomics analysis.

Methods Patients who underwent tubeless subxiphoid uniportal video-assisted thoracoscopic surgery via balance-shaped sternal elevation device in anterior mediastinal masses process at the Department of Thoracic Surgery, West China Hospital, Sichuan University from March to April 2025 were included, and their clinical data were analyzed. Results A total of 4 patients were included, with 2 males and 2 females, aged 58-75 years. The diameter of the tumor was 2.5-3.0 cm. The operation time was 60.0-150.0 min, intraoperative blood loss was 5-10 mL, pain score on the 3rd day after surgery was 0 points, and postoperative hospital stay was 2-3 days. All patients achieved complete resection of the masses and thymus without perioperative complications. Conclusion The tubeless subxiphoid uniportal video-assisted thoracoscopic surgery with percutaneous suspension technique via balance-shaped sternal elevation device technique optimizes surgical visualization and instrument maneuverability while avoiding complications related to conventional anesthesia and tubing, thereby markedly enhancing the minimally invasive profile of anterior mediastinal masses resections. In addition to maintaining procedural safety, this approach effectively reduces postoperative pain and accelerates patient recovery, highlighting its potential for widespread clinical adoption.

Background and aims:Metabolic dysfunction-associated fatty liver disease(MAFLD)is a common chronic condition that can lead to cancer due to its complex pathogenesis.Therapeutic agents targeting AMP-activated protein kinase(AMPK)activation have been suggested as potential treatments for metabolic disorders such as metabolic dysfunction-associated steatohepatitis(MASH).Rhizoma Atractylodis Mac-rocephalae(RAM)has been clinically used to treat obesity-related health problems,but its therapeutic effects on MAFLD and the underlying mechanism remain unclear.Therefore,this study was conducted to evaluate the function and underlying mechanism of RAM in the treatment of MAFLD.Methods:The effect of RAM decoction on MAFLD was evaluated using a high-fat diet(HFD)-induced MAFLD mouse model.In vitro studies were conducted using a palmitic acid/oleic acid-induced lipid accumulation model in the alpha mouse liver 12 cells and RAM-containing serum.The underlying mechanisms were elucidated through a combination of network pharmacology analysis,immunohis-tochemistry,western blotting,and polymerase chain reaction analysis.Results:Administration of RAM decoction significantly reduced body weight gain in MAFLD mice without changing food intake.The weights of the liver and inguinal adipose tissues were also reduced after RAM treatment.Additionally,RAM administration decreased serum levels of alanine aminotrans-ferase,aspartate transaminase,total cholesterol,triglyceride,low-density lipoprotein cholesterol,and glucose,while reducing lipid droplet accumulation in the liver tissues of MAFLD mice.The underlying mechanisms included the activation of the phosphorylation of AMPK and acetyl-CoA carboxylase(ACC),and inhibition of the expression of sterol regulatory element binding protein 1(SREBP1).However,RAM did not alter the protein expression levels of peroxisome proliferator-activated receptor α and carnitine palmitoyltransferase-1α.Furthermore,the RAM-induced upregulation of phosphorylated AMPK,phos-phorylated ACC,and SREBP1 expression,as well as the downregulation of fatty acid synthase expression,were reversed by using an AMPK inhibitor.Conclusions:Through a combination of network pharmacology and experimental validation,we demonstrated that RAM may exert therapeutic effects on MAFLD by inhibiting lipid synthesis and activating phosphorylated AMPK pathways.

Alzheimer disease(AD)is a common neurodegenerative disease with overall cognitive deterioration and mental and behavioral disorders,and due to unknown etiology and pathogenesis of AD,there is currently no effective medi-cation for AD.As a new noninvasive neuromodulation method,repetitive transcranial magnetic stimulation(rTMS)can improve cognitive impairment in patients with AD by regulating multiple pathways such as neural activity,synaptic plastic-ity,neurotransmitters,and neurotrophic factors.This article reviews the studies on the mechanism of action of rTMS in the treatment of AD in recent years,in order to clarify the mechanisms of rTMS such as anti-oxidation and regulation of synaptic plasticity.

Background and aims:Kehuang(KH)capsule is an herbal medical product approved for the treatment of liver diseases,including liver injury,in China.However,the mechanism is still unclear.This study aimed to elucidate the protective effects of KH capsule against carbon tetrachloride(CCl4)-induced acute liver injury(ALI)in a murine model.Methods:Mice were randomly divided into control,model(CCl4),CCl4+KH_Low and CCl4+KH_High group.Liver enzyme levels and histological changes were assessed to evaluate liver injury.Oxidative stress markers and inflammatory cell infiltration in liver tissues were measured.Additionally,network pharmacology was employed to explore the potential mechanisms of KH capsule.Results:KH capsule significantly reduced serum alanine aminotransferase(ALT)and aspartate amino-transferase(AST)levels,as well as the necrotic area in liver tissue.KH capsule also decreased the infil-tration of macrophages and neutrophils,thereby inhibiting the expression of interleukin-6(IL-6),tumor necrosis factor-alpha(TNF-α),and interleukin-1 beta(IL-1β).Furthermore,KH capsule decreased liver malondialdehyde(MDA)levels and increased superoxide dismutase(SOD)activity.The number of ter-minal deoxynucleotidyl transferase(TdT)-mediated dUTP nick-end labeling(TUNEL)-positive cells in liver tissue was also reduced.The expression of nuclear factor erythroid 2 related factor 2(Nrf2)and heme oxygenase-1(HO-1)proteins was significantly elevated,while the protein expression of cyto-chrome P450 2E1(CYP2E1)was significantly reduced.Mass spectrometry identified genistein,galangin,wogonin,skullcapflavone Ⅱ,and hispidulin as potential active ingredients of KH capsule.Network pharmacology analysis revealed enrichment in the mitogen-activated protein kinase(MAPK)and phosphatidylinositol 3-kinase(PI3K)-protein kinase B(AKT)signaling pathways.Western blot analysis confirmed that KH capsule suppressed AKT,extracellular signal-regulated kinase(ERK),and p38 signaling.Conclusions:These findings suggest that KH capsule could exert protective effects against CCl4-induced ALI,with the inhibition of MAPK and PI3K-AKT signaling pathways playing a crucial role in its mecha-nism of action.

Early diagnosis of pulmonary diseases is of great significance for their prevention and treatment. Serum Krebs von den Lungen-6 (KL-6) assay can reflect the damage degree of alveolar epithelium and stromal tissue, and is simple, non-invasive and low-cost. Pervious study showed that the serum KL-6 level was higher in patients with various interstitial lung diseases (e.g. idiopathic pulmonary fibrosis and connective tissue disease, primary Sjögren's syndrome, rheumatoid arthritis, idiopathic inflammatory myopathy and systemic sclerosis combined with interstitial lung disease), non-small cell lung cancer, various pneumonias and chronic obstructive pulmonary disease compared to healthy controls. Therefore, serum KL-6 has good sensitivity and specificity for the early diagnosis of these diseases. Occupational pneumoconiosis is an interstitial lung disease with a well-established etiology. Pervious study has shown that serum KL-6 level was higher in patients with occupational silicosis, occupational asbestosis, and dust-exposed workers compared to healthy controls. However, due to the limited sample size and the inconsistent findings on different studies, further research is needed to study the role of serum KL-6 in the early diagnosis of pneumoconiosis. Future studies should increase the sample size, improve the detection methods for serum KL-6, explore its feasibility as an early diagnostic biomarker for occupational pulmonary diseases, and investigate the efficacy andvalue of its combined application with other biomarkers in the early diagnosis of various pulmonary diseases, including occupational lung diseases, to fully exploit its predictive role in pulmonary diseases.
