ObjectiveTo investigate the safety and efficacy of transparent cap-assisted peroral cholangiopancreatoscopy-guided electrohydraulic lithotripsy （EHL）. MethodsA retrospective analysis was performed for the clinical data of 60 patients with large common bile duct stones who were admitted to Department of Gastroenterology， Jilin People’s Hospital， from May 1， 2023 to January 31， 2026， and according to the treatment method， the patients were divided into transparent cap-assisted peroral cholangiopancreatoscopy-guided electrohydraulic lithotripsy group and peroral cholangiopancreatoscopy-guided electrohydraulic lithotripsy group， with 30 patients in each group. The two groups were compared in terms of the rate of successful single-session stone fragmentation and removal， procedural time， duration of electrohydraulic lithotripsy， clinical success rate， and complications. The independent-samples t test or the Mann-Whitney U test was used for comparison of continuous data between two groups， and the chi-square test or the Fisher’s exact test was used for comparison of categorical data between two groups. ResultsCompared with the peroral cholangiopancreatoscopy-guided electrohydraulic lithotripsy group， the transparent cap-assisted peroral cholangiopancreatoscopy-guided electrohydraulic lithotripsy group had a significantly higher technical success rate （83.33% vs 60.00%， χ²=4.022， P=0.045） and significantly shorter procedural time ［46.00 （42.25 — 49.00） min vs 54.50 （42.00 — 65.00） min， Z=2.012， P=0.044］ and duration of electrohydraulic lithotripsy ［8.00 （6.25 — 11.75） min vs 13.50 （9.25 — 17.75） min， Z=2.749， P=0.006］. Both groups achieved a clinical success rate of 100%， with no significant difference in the incidence rate of complications （P>0.05）. ConclusionTransparent cap-assisted peroral cholangiopancreatoscopy-guided electrohydraulic lithotripsy has a high rate of successful single-session stone fragmentation and removal and a short procedural time， with good safety and efficacy， and therefore， it holds promise for clinical application.

Objective:To investigate the effect of polystyrene microplastics(PS-MPs)combined with high-fat treatment on vascular endothelial cells.Methods:Human umbilical vein endothelial cells(HUVECs)were cultured in the DMEM medium containing 5%fe-tal bovine serum.HUVECs were treated with conventional culture,high-fat treatment,and PS-MPs combined with high-fat treatment.The experiment was conducted in the three groups of control group,high-fat treatment group and PS-MPs+high-fat treatment group.CCK-8 assay was used to measure cell viability,F-actin staining was used to observe cell morphological changes,and flow cytometry,scratch assay,and tube formation assay were used to measure the apoptosis,migration,and tube-forming ability of cells.Results:After HUVECs were exposed to the high-fat environment,there was a significant reduction in cell viability,shrinkage of cells,a signifi-cant increase in cell apoptosis,and significant reductions in cell migration and tube-forming ability.Compared with the high-fat treat-ment group,there were no significant changes in cell viability,cell morphology,cell apoptosis,and cell migration ability after PS-MPs combined with high-fat treatment,but the tube-forming ability of cells was further impaired.Conclusion:High-fat treatment will affect cell viability,change cell morphology,and damage vascular endothelial cell function,and PS-MPs combined with high-fat treat-ment can aggravate the damage of vascular endothelial cell function.

Objective To identify potential biomarkers and establish a prediction model for chemotherapy-related hepatotoxicity susceptibility based on plasma endogenous metabolites of colorectal cancer(CRC)patients before chemotherapy.Methods The plasma samples of 50 CRC patients before capecitabine chemotherapy and the records of their chemotherapy-related hepatotoxicity during the follow-up were collected.An ultra-high-performance liquid chromatography coupled to quadrupole time-of-flight mass spectrometry(UHPLC-Q-TOF-MS)was used to perform untargeted metabolomic analysis.Based on bioinformatics analysis,differential analysis,correlation analysis,and random forest were used to screen for hepatotoxicity-related plasma endogenous metabolites.All samples were randomly assigned(7∶3)to training set or test set.A multivariate logistic regression model was established to predict the hepatotoxicity of capecitabine chemotherapy based on the training set data.The prediction effects of the model in the training,test and entire sets were evaluated by receiver operating characteristic(ROC)curve analysis.Results The endogenous metabolites related to hepatotoxicity in the plasma of CRC patients before chemotherapy were mainly lipid endogenous metabolites.A series of potentially important predictive biomarkers for hepatotoxicity susceptibility were identified,including sphingamine-1-phosphate,ceramide,galactose,arachidonic acid,tyrosine,biliverdin,myristic acid,phosphatidylcholine(35∶1),phosphatidylethanolamine(36∶1),and hexadecanoic acid.The area under curve values of the prediction model based on the above biomarkers in the training,test and entire sets were 0.946(95%confidence interval[CI]0.842-1.000),0.920(95%CI 0.720-1.000),and 0.912(95%CI 0.810-0.982),respectively.Conclusion The endogenous metabolites in the plasma of CRC patients before chemotherapy can effectively predict the hepatotoxicity of capecitabine chemotherapy.These hepatotoxicity biomarkers indicate that susceptible patients have characteristics related to lipid metabolism disorders.

This article summarizes Professor TIAN Conghuo's key points and features of acupuncture for primary dysmenorrhea. Professor TIAN believes that the location of dysmenorrhea is in the uterus, and the fundamental pathogenesis is the disharmony of both form and spirit. During clinical treatment, he first conducts abdominal palpation, often detecting cord-like nodules around Guilai (ST 29), Huangshu (KI 16), and Zigong (EX-CA 1). Needling reaches the depth of these nodules. Additionally, the use of four acupoints around the navel (Shuifen [CV 9], bilateral Huangshu (KI 16), and Yinjiao [CV 7]), and four back-shu points (Ganshu [BL 18], Pishu [BL 20], Shenshu [BL 23], and Geshu [BL 17]) is applied to regulate the spirit and strengthen the body. Point selection is further based on syndrome differentiation. The "Three layers" needling technique is used, emphasizing the mental and emotional state of the patients, calming the spirit and regulating qi and blood, to achieve a harmonious treatment of both form and spirit for dysmenorrhea.
