Objective To analyze the main causes and risk factors of unplanned reoperation after liver transplantation. Methods The clinical data of 242 liver transplant recipients in the First Affiliated Hospital of Anhui Medical University from January 2015 to December 2024 were retrospectively analyzed. According to whether unplanned reoperation was performed during the same hospitalization after surgery, the recipients were divided into the reoperation group (n=36) and the non-reoperation group (n=206). The preoperative, intraoperative and postoperative data of the two groups, as well as donor and graft-related data, were compared to analyze the risk factors of unplanned reoperation after liver transplantation and the survival status of the two groups. Results Among the 242 liver transplant recipients, 36 underwent unplanned reoperations, with a total of 54 procedures including various laparotomies, endoscopic and interventional surgeries, among which there were 20 laparotomies, 18 endoscopic surgeries and 16 interventional surgeries. The most common cause of unplanned reoperation was biliary complications (20 times), followed by vascular complications (17 times). Compared with the non-reoperation group, the reoperation group had longer graft cold ischemia time, higher postoperative fatality rate of recipients, longer length of stay in the intensive care unit and postoperative hospital stay, and higher total hospitalization costs (all P<0.05). The incidence of unplanned reoperation was higher in recipients who underwent split liver transplantation (P<0.05). Multivariate analysis showed that intraoperative blood loss ≥1 000 mL, positive culture of graft perfusate and split liver transplantation were independent risk factors for unplanned reoperation (all P<0.05). The postoperative 7-day, 1-month, 3-month and 6-month survival rates of recipients in the reoperation group and the non-reoperation group were 100% vs. 98.1%, 88.9% vs. 94.2%, 69.4% vs. 90.8% and 66.7% vs. 90.8%, respectively, and the postoperative survival rate of recipients in the reoperation group was lower than that in the non-reoperation group (P<0.05). Conclusions The main causes of unplanned reoperation after liver transplantation are biliary complications, vascular complications, abdominal incision infection and intra-abdominal hemorrhage. Intraoperative massive blood loss, positive culture of graft perfusate and split liver transplantation are the risk factors associated with unplanned reoperation after liver transplantation.

Objective To explore the dominant views with positive results when performing echocardiography on common congenital heart disease (CHD) in children using the seven-step screening method for pediatric echocardiography. Methods The echocardiographic data of children with atrial septal defect, patent foramen ovale, ventricular septal defect, and patent ductus arteriosus were collected from September 2021 to February 2022. The disease type distribution, view distribution, and the dominant view distribution were analyzed. Dominant view referred to the view with a high ratio of positive result images per view to the total image in each disease. Results A total of 8 353 images of 1 633 children with common CHD were collected. There were 813 males and 820 females ageed 0-7 years, including 3 613 images in 701 patients with atrial septal defect, 1 178 images in 206 patients with patent foramen ovale, 2 857 images in 576 patients with ventricular septal defect, and 705 images in 150 patients with patent ductus arteriosus. The dominant views of atrial septal defect were subxiphoid 2-chamber view (92.96%), subxiphoid 4-chamber view (85.61%), parasternal 4-chamber view (62.07%), and parasternal short-axis view (38.50%). The dominant views of patent foramen ovale were subxiphoid 2-chamber view (82.69%) and subxiphoid 4-chamber view (65.41%). The dominant views of ventricular septal defect were parasternal 5-chamber view (79.73%), parasternal short-axis view (79.41%), parasternal 4-chamber view (58.18%), and parasternal long-axis view (51.11%). The dominant view of patent ductus arteriosus was parasternal short-axis view (98.80%). Conclusion The analysis of the lesion key areas of common CHD shows that there are 4 dominant views for atrial septal defect and ventricular septal defect, 2 for patent foramen ovale, and only 1 for patent ductus arteriosus. Clarifying the dominant views of common CHD is conducive to rapid and accurate diagnosis of diseases, clinical practice, teaching and scientific research.

Objective To investigate the effects of dapagliflozin on the risk of malignant ventricular arrhythmia(MVA)during hospitalization in patients with acute myocardial infarction(AMI).Methods A retrospective study was conducted to select patients with AMI who underwent percutaneous coronary intervention(PCI)in the department of cardiology of the Third Affiliated Hospital of Nanjing Medical University between January 2018 and November 2023.Clinical datas collected during hospitalization included demographics(gender,age),baseline vital signs(systolic blood pressure,diastolic blood pressure,heart rate),comorbidities(hypertension,diabetes mellitus),body mass index(BMI),smoking,alcohol consumption,ST segment elevation myocardial infarction(STEMI),Killip class≥3,laboratory parameters[white blood cell count(WBC),neutrophil percentage(NEU%),serum creatinine(SCr)],procedural data(number of coronary stents implanted,culprit vessels being the left main coronary artery,left anterior descending artery,right coronary artery,left circumflex artery and intraoperative hypotension),medications[angiotensin converting enzyme inhibitor/angiotensinⅡreceptor blocker(ACEI/ARB),β-blockers,aspirin,ticagrelor,clopidogrel,platelet glycoproteinⅡb/Ⅲa receptor antagonists,Statin],and electrocardiogram characteristics[the number of cases frequent ventricular premature contractions(premature beats)and the number of cases of sinus rhythm].The study endpoint was the occurrence of MVA during hospitalization among enrolled patients.Patients were categorized into the MVA group and the non-MVA group based on the occurrence of MVA during their hospital stay.Differences in clinical characteristics between the two groups were compared.Univariate and multivariate Logistic regression analyses were employed to evaluate the impact of dapagliflozin use on the risk of MVA in patients with AMI.Results A total of 2 893 eligible AMI patients were enrolled and 145 patients(5.01%)experienced MVA during hospitalization.Compared with the MVA group,the proportion of patients taking dapagliflozin was higher in the non-MVA group[13.2%(363/2 748)vs.6.2%(9/145),P=0.014],the proportion of males was higher[74.3%(2 042/2 748)vs.66.9%(97/145),P=0.048],the age was younger(years:64.82±13.91 vs.69.78±14.07,P<0.001),the heart rate at admission was slower(beats/min:80.09±15.72 vs.84.31±20.92,P=0.002),the proportion of patients with Killip grade≥3 was lower[11.5%(317/2 748)vs.38.6%(56/145),P<0.001],the proportion of smoking patients was higher[48.0%(1 319/2 748)vs.33.8%(49/145),P<0.05],SCr level was lower(μmol/L:84.73±58.52 vs.102.87±59.47,P<0.001),and the proportion of patients taking ACEI/ARB and β-blockers was higher[64.9%(1 783/2 748)vs.49.0%(71/145),65.1%(1 788/2 748)vs.53.8%(78/145),both P<0.05],the rate of frequent premature ventricular beats was lower[1.0%(28/2 748)vs.11.7%(17/145),P<0.05],and the proportion of patients with intraoperative hypotension was lower[3.2%(86/2 748)vs.10.6%(15/145),P<0.05].After adjusting numerous confounding factors,multifactorial Logistic regression analysis showed that dapagliflozin may significantly reduced the risk of MVA in patients with AMI after PCI[odds ratio(OR)=0.417,95%confidence interval(95%CI)was 0.200-0.880,P=0.022].Subgroup analysis suggested that there were 1 042 AMI patients with diabetes mellitus,of whom 348 took dapagliflozin,and 8 patients(2.30%)had MVA.The risk of MVA was reduced in patients taking dapagliflozin(Log-Rank:χ2=11.983,P=0.001).Conclusion The use of dapagliflozin significantly reduced the risk of MVA during hospitalization in patients with AMI.

Objective To investigate the factors that influence ocular surface biology and visual acuity in individuals with diabetic dry eye(DDE)and analyze how these factors contribute to changes in visual quality.Methods Based on the disease duration,fasting blood glucose(FBG),and glycated hemoglobin(HbA1c)levels of patients with type 2 diabe-tes mellitus(T2DM),the DDE patients were divided into different groups.Logistic regression analysis was used to identify influencing factors related to ocular surface biology and visual quality in each group of DDE patients.Tear film stability was evaluated based on the tear film rupture time(BUT),Schirmer I test(SIt),and ocular surface disease index(OSDI).Lip-iview? Surface interferometers were used to measure tear film lipid layer thickness(LLT),meibomian gland loss rate(MGP),meibomian gland opening number(MGYLS),and meibomian gland secretion score(MGYSS).Wavefront aber-rometry was used to measure corneal wavefront aberration values at 4 mm and 6 mm pupil diameters.Ocular response ana-lyzer(ORA)was adopted to analyze corneal hysteresis(CH)and corneal resistance factor(CRF).Moreover,ELISA ex-periment to evaluate the trend of changes in inflammatory factors in tears.Results Logistic regression analysis revealed that T2DM duration,smoking history,FBG,HbA1c,total cholesterol(TC),triglycerides(TG),OSDI score,LLT,BUT,SIt,MGP,MGYLS,MGYSS,total higher-order aberrations,spherical aberration,coma aberration,trefoil aberration,tumor necrosis factor-α,interleukin-6,matrix metalloproteinase-9,receptor for advanced glycation end products,and insu-lin were all influencing factors for the risk of DDE(all P＜0.05).As the T2DM course prolonged and FBG or HbA1 c levels rose,tear film-related indicators(LLT,BUT,and SIt)and meibomian gland-related indicators(MGYLS and MGYSS)inpa-tients gradually decreased,while OSDI scores and MGP gradually increased(all P＜0.05).As the T2DM course prolonged and FBG or HbA1c levels rose,the total higher-order aberrations,spherical aberration,coma aberration,and trefoil aber-ration in DDE patients under 4 mm and 6 mm pupil diameters gradually increased;Meanwhile,best corrected visual acuity,corneal hysteresis,and corneal resistance factor gradually decreased;The contents of tumor necrosis factor-α,interleukin-6,matrix metalloproteinase-9,receptor for advanced glycation end products,and insulin in tears all gradually increased,while mucin-5AC gradually decreased(all P＜0.05).Conclusion With the prolongation of T2DM duration and the in-crease of FBG or HbA1c,the ocular surface inflammatory response in DDE patients gradually worsens,corneal biological function decreases,and visual quality deteriorates.Timely systemic and local interventions are of great significance for im-proving dry eye symptoms and visual quality in DDE patients.

Objective To investigate the factors influencing hyperdynamic circulation-related indicators in patients with liver cirrhosis and ascites.Methods A retrospective analysis was conducted on the clinical data of 377 patients diagnosed with cirrhosis-associated ascites at the Third People's Hospital of Kunming between October 2022 and October 2024.Patients were categorized into grade 1,grade 2,and grade 3 ascites groups according to ascites severity grading.The general demographic characteristics and clinical parameters of the three groups were compared.Potential positive predictors were initially identified through univariate analyses,including Spearman correlation and non-parametric tests.Binary logistic regression and multiple linear regression models were subsequently employed to investigate the factors influencing high dynamic circulation-related indicators(heart rate[HR],E/A ratio,and left ventricular diastolic function[LVDF])in patients with cirrhosis-related ascites.Results Significant differences in the incidence of HR,the ratio of early to late diastolic filling velocities(E/A),and LVDF were observed among different ascites groups(P<0.05).Age,ascites depth,serum chloride(Cl-),CO2,red cell distribution width coefficient of variation(RDW-CV),and etiology were identified as independent determinants of HR in patients with liver cirrhosis and ascites.Age,white blood cell count(WBC),albumin(ALB),and etiology were independent determinants of E/A in patients with liver cirrhosis and ascites.Age(OR=1.088,95%CI 1.062-1.114,P<0.001)and serum potassium(K+)(OR=1.919,95%CI 1.218-3.025,P=0.005)were independent risk factors for LVDF in patients with cirrhotic ascites,whereas RDW-CV(OR=0.902,95%CI 0.883-0.961,P=0.023)and ALB(OR=0.921,95%CI 0.883-0.961,P<0.001)were identified as protective factors.Conclusions Serum ALB is an independent influencing factor for E/A ratio and LVDF in cirrhotic patients with ascites and hyperdynamic circulation.K+and RDW-CV are also independent predictors of LVDF,whereas Cl-independently influences heart rate.Clinical monitoring and targeted intervention for these parameters should be emphasized.

Epileptic seizure classification serves as an essential tool for evaluating seizures in clinical practice. In 2025, the International League Against Epilepsy updated the classification framework for epileptic seizures. An interpretation of the key updates is provided, with detailed content presented below: "onset" is removed from the names of the main seizure classes; consciousness is used as a classifier instead of awareness; the dichotomy of motor and non-motor is replaced by observable vs nonobservable manifestations; epileptic negative myocionus is recognized as a seizure type, to clarify the key updates to facilitate better application of the consensus in clinical practice.

Background: The genetic basis for hyperglycaemia in pregnancy remain unclear. This study aimed to uncover the genetic determinants of gestational diabetes mellitus (GDM) and investigate their applications. Methods: We performed a meta-analysis of genome-wide association studies (GWAS) for GDM in Chinese women (464 cases and 1,217 controls), followed by de novo replications in an independent Chinese cohort (564 cases and 572 controls) and in silico replication in European (12,332 cases and 131,109 controls) and multi-ethnic populations (5,485 cases and 347,856 controls). A polygenic risk score (PRS) was derived based on the identified variants. Results: Using the genome-wide scan and candidate gene approaches, we identified four susceptibility loci for GDM. These included three previously reported loci for GDM and type 2 diabetes mellitus (T2DM) at MTNR1B (rs7945617, odds ratio [OR], 1.64; 95% confidence interval [CI],1.38 to 1.96]), CDKAL1 (rs7754840, OR, 1.33; 95% CI, 1.13 to 1.58), and INS-IGF2-KCNQ1 (rs2237897, OR, 1.48; 95% CI, 1.23 to 1.79), as well as a novel genome-wide significant locus near TBR1-SLC4A10 (rs117781972, OR, 2.05; 95% CI, 1.61 to 2.62; Pmeta=7.6×10-9), which has not been previously reported in GWAS for T2DM or glycaemic traits. Moreover, we found that women with a high PRS (top quintile) had over threefold (95% CI, 2.30 to 4.09; Pmeta=3.1×10-14) and 71% (95% CI, 1.08 to 2.71; P=0.0220) higher risk for GDM and abnormal glucose tolerance post-pregnancy, respectively, compared to other individuals. Conclusion Our results indicate that the genetic architecture of glucose metabolism exhibits both similarities and differences between the pregnant and non-pregnant states. Integrating genetic information can facilitate identification of pregnant women at a higher risk of developing GDM or later diabetes.

Objective To explore the relationship between corrected QT interval(QTc)and short-term mortality rate in patients with cirrhotic ascites and the predictive value of QTc combined with Child-Pugh class for short-term death.Methods Patients hospitalized with cirrhotic ascites from October 2022 to March 2024 were selected as study subjects(training set,n=245),and similar patients from April to October 2024 were included for external validation(validation set,n=88).Patients'demographic data,basic clinical data,and first electrocardiography related indicators on admission were collected.Patients were divided into a death group and a survival group according to the 30-day follow-up result.The influencing factors for prognosis were explored by Lasso regression and univariate and multivariate binary logistic regression.A death risk nomogram model was constructed and evaluated by receiver operating characteristic curve(ROC curve),calibration curve,and decision curve.Data were analyzed for normality using Shapiro-Wilk test.Pairwise comparison for continuous data that were normally distributed was conducted by the independent-samples t test.Pairwise comparison for continuous data that were not normally distributed was conducted by the Mann-Whitney U test.Pairwise comparison for categorical data was performed using the chi-square test.Results The mortality rates were 35.1%(86/245)in the training set and 30.7%(27/88)in the validation set.Lasso regression showed that combined tumor,QTc,hematocrit,total bilirubin(TBil),direct bilirubin,alkaline phosphatase,albumin,cholinesterase,high-density lipoprotein cholesterol,carcinoembryonic antigen,international normalized ratio,model for end-stage liver disease(MELD),and Child-Pugh class were potential influencing factors for 30-day death in patients with cirrhotic ascites.Univariate and multivariate logistic regression showed that QTc(odds ratio[OR]=1.010,95%confidence interval[CI]:1.001-1.020,P=0.039),presence of tumor(OR=6.904,95%CI:2.997-12.391,P<0.001),TBil(OR=1.009,95%CI:1.004-1.014,P=0.001),and Child-Pugh class(OR=2.532,95%CI:1.256-5.105,P=0.009)were independent risk factors for 30-day death in patients with cirrhotic ascites.For the nomogram model constructed based on the results of the multivariate logistic analysis,the area under the ROC curve in the training set was 0.824;the sensitivity and specificity were 81.1%and 74.4%,respectively;the Hosmer-Lemeshow goodness-of-fit test showed P=0.673;the mean absolute error of the calibration curve was 0.020.The area under the ROC curve in the validation set was 0.886;the sensitivity and specificity were 91.8%and 70.4%,respectively;the Hosmer-Lemeshow goodness-of-fit test showed P=0.965;the mean absolute error of the calibration curve was 0.032.With the threshold probability of 0.15 to 0.85,the decision curve suggested a good benefit.The area under the ROC curve of the predictive model(0.824)was greater than conventional MELD score(0.700),MELD-Na score(0.698),and Child-Pugh score(0.674)(all P<0.05).Conclusion QTc is an independent predictor of short-term death in patients with cirrhotic ascites,and the prognostic model including QTc and Child-Pugh class has a good predictive value for short-term mortality rate.
