Objective:To explore the effect of preoperative gamma-glutamyl transferase to albumin ratio (GAR) on prognosis of patients with Barcelona clinic liver cancer (BCLC)stage 0-A hepatocellular carcinoma (HCC) after microwave ablation (MWA).Methods:The clinical data of 201 patients with BCLC stage 0 to A who underwent MWA at two centers of Jiaxing Second Hospital and Shengjing Hospital of China Medical University from January 2011 to December 2018 were retrospectively analyzed, including 152 males and 49 females, aged (57.5±9.6) years. X-tile software was used to divide patients into a low GAR group ( n=84, GAR<0.9) and a high GAR group ( n=117, GAR≥0.9). Kaplan-Meier method was used for survival analysis, and log-rank test was used for survival comparison. Univariate and multivariate Cox regression analysis was used to evaluate the relationship between GAR and prognosis. Results:The cumulative survival rates at 1, 3 and 5 years postoperatively were 98.7%, 93.8%, 78.5% for the low GAR group, which were superior to that 97.2%, 87.1%, 70.2% for the high GAR group, and the difference was statistically significant ( χ2=11.89, P=0.001). The recurrence-free survival rates at 1, 3 and 5 years after surgery between the two groups was no significant difference ( χ2=1.70, P=0.192). Multivariate analysis revealed that high GAR ( HR=2.723, 95% CI: 1.508-4.914, P=0.001) was independent risk factors for overall survival after MWA in patients with BCLC stages 0 to A HCC. Male gender ( HR=1.959, 95% CI: 1.127-3.305, P=0.017) and tumor diameter ≥2 cm ( HR=1.547, 95% CI: 1.008-2.373, P=0.046) were independent risk factors for recurrence after MWA in patients with BCLC stages 0 to A HCC. Univariate analysis, GAR≥0.9 was not associated with postoperative recurrence ( HR=1.315, 95% CI: 0.869-1.989, P=0.195). Conclusion:Preoperative GAR (≥0.9) is an independent risk factor affecting overall survival in patients with BCLC stages 0 to A HCC after MWA.

Objective To investigate influencing factors of textbook outcome(TO)in patients with pancreatic ductal adenocarcinoma undergoing minimally invasive pancreaticoduodenectomy(MIPD).Methods A retrospective analysis was conducted on the clinical data of 101 cases of pancreatic ductal adenocarcinoma treated with MIPD in our hospital from January 2020 to December 2022.According to the inclusion and exclusion criteria,89 cases were ultimately included in this study,of which 61 cases reached TO(TO group)and 28 cases did not reach TO(non-TO group).Variables with P<0.05 in univariate analysis were included in multivariate logistic regression analysis to identify independent prognostic factors of TO.Results Univariate analysis showed that there were significant differences in pancreatic duct dilation>3 mm,preoperative neutrophil lymphocyte ratio(NLR),extended hospital stay,postoperative hospitalstay,and drain fluid amylase(DFA)>1100 U/L at1-3 d aftersurgery(P<0.05).Multivariate logistic regression analysis showed that the independent prognostic factors affecting TO were:pancreatic duct dilation>3 mm(OR=7.290,95%CI:1.485-35.786,P=0.014),postoperative hospital stay(OR=0.862,95%CI:0.751-0.989,P=0.034),and the DFA on the first postoperative day>1100 U/L(OR=0.052,95%CI:0.005-0.545,P=0.014).Conclusions The outcome of TO in patients after MIPD is not related to the surgical approach(robot assisted minimally invasive pancreaticoduodenectomy or laparoscopic pancreaticoduodenectomy).Pancreatic duct dilation>3 mm,postoperative hospital stay,and DFA on the first postoperative day>1100 U/L are independent prognostic factors of TO after MIPD in patients with pancreatic ductal adenocarcinoma.

Objective:This multicenter retrospective study aimed to analyze the clinicopathological features of duodenal adenocarcinoma (DA) and identify prognostic factors for postoperative survival.Methods:Demographic characteristics, clinicopathological features, treatment outcomes and survival of DA patients undergoing surgical treatment at 18 Chinese medical centers from January 2012 to December 2023 were retrospectively analyzed.Results:Among the 2 056 DA patients included, 46.8% (963) had extra-ampullary DA (EA-DA), and 53.2% (1 093) had peri-ampullary DA (PA-DA). The 1-, 3-, and 5-year overall survival (OS) rates for patients who underwent radical surgery were 93.2%, 71.0%, and 57.2%, respectively. The median overall survival was 76 months, and the median progression-free survival (PFS) was 65 months. No differences in survival were observed between the laparotomy group and minimally invasive surgery (MIS) group either before or after propensity score matching (OS: 76 vs. 75 months before PSM, P=0.986; OS: 75 vs. 75 months after PSM, P=0.602). Furthermore, there were no significant differences between-group in operation time and postoperative complications ( P＞0.05). The MIS group experienced less intraoperative blood loss and shorter hospital stays. The multivariate Cox regression analysis revealed that advanced age ( HR=1.43,95% CI:1.18-1.73), elevated carbohydrate antigen 19-9 levels ( HR=1.24,95% CI:1.02-1.51), perineural invasion ( HR=1.44,95% CI:1.14-1.81), vascular invasion ( HR=1.35,95% CI:1.07-1.71), advanced T stage (T3-4 vs. T1-2: HR=1.86,95% CI:1.49-2.31), regional lymph node metastasis ( HR=1.93,95% CI:1.58-2.36), preoperative biliary drainage ( HR=1.26,95% CI:1.04-1.53), intraoperative blood loss ( HR=1.34,95% CI:1.11-1.62), clinically significant postoperative pancreatic fistulas ( HR=1.53,95% CI:1.12-2.09), and postoperative hemorrhage ( HR=1.62,95% CI:1.14-2.29) were independent risk factors for poor prognosis after surgery (all P＜0.05). Conclusions:Radical surgery is associated with favorable overall survival among DA patients, and no difference in survival is observed between EA-DA and PA-DA patients. MIS is a reliable alternative for DA treatment.

Objective:To investigate the therapeutic value of visual endoscopic retrograde appendicitis therapy (vERAT) in pediatric patients with acute suppurative appendicitis (ASA).Methods:This was a retrospective cohort study. A total of 55 ASA patients who underwent vERAT at the Pediatric Department of the Tangdu Hospital of Air Force Medical University between November 2023 and January 2025 were selected and divided into groups based on the presence or absence of fecaliths: fecalith group and non-fecalith group. The baseline characteristics, initial treatment success rates, treatment costs, hospital stay duration, procedure time, and recurrence rates between two groups were compared. Mann-Whitney U test and χ2 test were used to evaluate group differences. Results:A total of 55 ASA patients were enrolled, including 38 males and 17 females, with the age of 11.2 (9.2, 13.1) years. Based on the presence of fecaliths, patients were divided into two groups: fecalith group (32 cases) and non-fecalith group (23 cases). No statistically significant differences were observed between the two groups in terms of age, gender, duration of abdominal pain, white blood cell count, neutrophil percentage, diameter of appendix, thickness of appendix clinical symptoms or signs (all P>0.05). The initial treatment success rates were 91% (29/32) in fecalith group and 96% (22/23) in non-fecalith group, with no statistically significant difference ( P=0.632). However, significant differences were noted in stent placement ( χ2=5.85, P=0.026) and procedure time ( Z=4.75, P<0.001). The follow-up duration time was 6.0 (2.0, 12.0) and 7.0 (2.0, 8.5) months for the fecalith and non-fecalith groups, respectively, with no significant difference ( Z=0.05, P=0.962). The recurrence rates were 14% (4/29) in fecalith group and 5% (1/22) in non-fecalith group, with no statistically significant difference ( P=0.375). Conclusions:vERAT can safely and effectively treat pediatric ASA, regardless of the presence or absence of fecaliths. It can provide a new treatment option for ASA.

Objective:To establish 30-day of age transcutaneous bilirubin (TcB) reference curves for healthy neonates, and to investigate regional variations in bilirubin dynamics.Methods:A multicenter retrospective cohort study was conducted. A total of 220 950 healthy neonates born at a gestational age of 35-<42 weeks, with a birth weight ≥2 000 g, who did not receive phototherapy within 60 h after birth were recruited. All of them underwent remote TcB monitoring using the Bilibaby remote jaundice monitoring system between August 1 st, 2020 and December 31 st, 2024 in 426 hospitals. TcB data were collected within the period from birth to 30-day of age. The P40, P75, and P95 of TcB values were calculated, and dynamic TcB curves for 30-day of age were constructed. Patterns of bilirubin change, rates of change, and transition outcomes were described. Regional comparisons between South and North were conducted using linear mixed-effects models for TcB trajectories and Pearson′s chi-square test for outcome differences. Results:A total of 220 950 neonates were included, of whom 101 711 (46.03%) were female. Gestational age at birth was (38.75±1.12) weeks, and birth weight was (3 272±417) g. TcB levels increased rapidly within 3-day of age, peaked at 4-6-day of age, with peak values at P40, P75, and P95 of 200.6, 239.7 and 275.4 μmol/L (11.8, 14.1 and 16.2 mg/dl), respectively. TcB levels gradually declined thereafter and stabilized after 13-day of age, with values at P40, P75, and P95 fluctuating between 147.9-159.8, 190.4-200.6, and 231.2-239.7 μmol/L (8.7-9.4, 11.2-11.8, 13.6-14.1 mg/dl), respectively. Notably, among neonates categorized as low-or low-intermediate-risk within 3-day of age, 6 700 (12.76%) progressed to intermediate-high or high risk between 4 and 30 days of age. Before 13-day of age, TcB levels in the southern regions were consistently higher than those in the northern regions ( P=0.039); from 14 to 30 days of age, the overall TcB levels had no statistically difference, but the temporal changes in TcB still showed regional differences (degrees of freedom=3, all interaction P<0.05). Among neonates classified as low-or low-intermediate risk within 3-day of age, 25 326 were from southern regions, of whom 4 254 (16.80%) progressed to intermediate-high or high risk between 4 and 30 days of age. In northern regions, 27 193 neonates were classified as low-or low-intermediate risk within 3-day of age, among whom 2 446 (8.99%) progressed to intermediate-high or high risk. The risk progression between the 2 regions had statistically difference ( χ2=716.49, P<0.001). Conclusions:A TcB percentile curve for neonates within 30-day of age was established, revealing that both the overall TcB level and its temporal trend were higher in southern than in northern newborns. These findings provide baseline data to support continuous management of neonatal jaundice.

Children who ingest corrosive substances by mistake usually have a small amount of exploratory ingestion，so perforation caused by injury is rare，and emergency surgical treatment is rarely required in the acute stage.But it is very easy to cause esophageal stenosis in the long term.Esophageal stenosis can last for weeks to months，and the children's difficult swallowing can lead to chronic pain in the esophagus and long-term malnutrition.At present，the main clinical treatment is endoscopic esophageal dilation，which requires multiple dilation treatments.The treatment period of corrosive esophageal stenosis in children is long，if supplemented with effective drugs during treatment，it is expected to reduce the degree of esophageal stenosis，reduce the number of dilation，and shorten the treatment period.On the other hand，early administration of protective drugs can promote benign wound healing after esophageal injury.This article reviews the research progress on drug treatment for corrosive esophageal stenosis in children.

Objective To investigate the rehabilitation efficacy of Beckman oral-motor training combined with auditory integration training(AIT)in children with language development delay.Methods A total of 118 children diagnosed with language development delay were enrolled in this study,and randomly assigned to auditory training group or combined training group,with 59 cases in each group.Children in the auditory training group received AIT,while those in the combined train-ing group underwent Beckman oral-motor training combined with AIT.The clinical efficacy,intellec-tual development,language ability,oral motor function,articulation ability,and serum neurotrophic factor levels of the two groups were observed and compared.Results After treatment,the overall ef-fective rate in the combined training group was 93.22％(55/59),which was significantly higher than 79.66％(47/59)in the auditory training group,with a statistically significant difference(P＜0.05).Following treatment,the scores of intellectual development,language ability,oral motor function,and articulation ability,as well as the serum levels of brain-derived neurotrophic factor(BDNF)and nerve growth factor(NGF)in both groups were elevated compared to the pre-treatment levels.Moreover,these parameters in the combined training group were superior to those in the audi-tory training group,and the differences were statistically significant(P＜0.05).Conclusion Beck-man oral-motor training combined with AIT can enhance the rehabilitation outcome in children with language development delay,improving their speech function,intellectual development,oral motor function,articulation ability,and serum neurotrophic factor levels.

Objective To investigate the feasibility of using the cell-free DNA(cfDNA)carrying tissue-specific mutations as biomarkers for assessing the severity of exercise-induced tissue injury.Methods Based on a public gene expression database,ten tissue-specific and highly-expressed genes were selected for each of ten different human tissues.A total of 34 young healthy volunteers were recruited,and their peripheral blood samples were collected after running 5 km per day for one week.Genomic DNA from leukocytes,plasma exosomal RNA,and plasma cfDNA were extracted and subjected to high-throughput sequencing respectively.Tissue-specific somatic mutations in plasma exosomal RNA were identified,and the relationship between cfDNA carrying these mutations and traditional protein biomarkers was analyzed.Results Tissue-specific cfDNA mutations related to five tissues(myocardium,skeletal muscle,intestine,stomach,and kidney)were detected in more than five volunteers.The correlation coefficients between total plasma cfDNA levels and the levels of tissue-specific protein biomarkers associated with these five tissues were less than 0.3(n=34,r=-0.51-0.28,P=0.0022-0.65).Notably,for each specific tissue,the levels of tissue-specific cfDNA mutations were positively correlated with the corresponding protein biomarker levels,and correlation coefficients were over 0.8(n=7-13,r=0.81-0.92,P=9.0×10-4-0.020).Conclusion Tissue-specific cfDNA mutations may serve as novel potential biomarkers for non-invasive evaluation of exercise-related tissue injury.

This paper presents a case of interstitial lung disease(ILD)during anti-tumor therapy in an elderly breast cancer patient,along with the subsequent glucocorticoid treatment course.Based on the patient's symptoms,signs and comprehensive evaluation of laboratory and imaging findings,and review of relevant literature,the ILD was suspected to be associated with abemaciclib.The causal relationship was determined as highly likely,according to the Common Terminology Criteria for Adverse Events,the severity of the ILD was evaluated as grade 2.The abemaciclib were discontinued and glucocorticoids were administered for anti-inflammation,supplemented with rabeprazole for gastric protection.During the treatment,disease recurrence occurred,which was considered related to overly rapid tapering of glucocorticoid dosage,prompting subsequent dose adjustment and slow reduction of glucocorticoids.Follow-up showed that the patient's ILD had improved.Clinical pharmacists assisted physicians in the differential diagnosis of adverse drug reactions and provided pharmaceutical care,participated in adjusting treatment plans,delivered medication education to patients,and ensured the safety and effectiveness of drug therapy.

Objective This study aims to elucidate the functional mechanism through which seminal plasma exosomal miR-26a-5p and its target genes contribute to idiopathic teratozoospermia,with emphasis on their regulatory pathways in sperm morphogenesis defects,thereby establishing a theoretical foundation for novel diagnostic markers and targeted therapies.Methods A case-control study design was adopted,enrolling 154 male subjects(84 in the teratozoospermia group[TZS]and 70 in the normal control group[NC]).Seminal plasma exosomes were isolated to screen differentially expressed miRNAs,followed by prediction and analysis of target genes and signaling pathways.Dual-luciferase reporter gene assays were employed to validate the direct binding of miR-26a-5p to PTEN.Quantitative real-time PCR and Western blot were used to measure miRNA and protein expression levels.Spearman correlation analysis evaluated relationships between miR-26a-5p,PTEN,and sperm morphological parameters,while ROC curve analysis assessed diagnostic efficacy.Results Seminal plasma exosomal miRNA sequencing identified 11 differentially expressed miRNAs,with miR-26a-5p significantly upregulated in the TZS group(P<0.05)and negatively correlated with the percentage of normal sperm morphology in TZS(r=-0.762,P<0.05).PTEN was confirmed as a direct target of miR-26a-5p,with its expression significantly reduced in the TZS group(P<0.05)and positively correlated with normal sperm morphology(r=0.821,P<0.05).A negative correlation was observed between miR-26a-5p and PTEN(r=-0.878,P<0.05).Dual-luciferase assays demonstrated that miR-26a-5p specifically inhibited PTEN 3'UTR activity(45%reduction in luciferase activity,P<0.05).Functional enrichment analysis revealed that the miR-26a-5p-PTEN axis exacerbates oxidative stress,DNA damage,and abnormal spermatocyte division by regulating the PI3K/AKT/mTOR,p53,Wnt/β-catenin,and NF-κB pathways.ROC analysis showed diagnostic efficacy for teratozoospermia with AUCROC values of 0.785(sensitivity 78.9%,specificity 71.3%)for miR-26a-5p and 0.754(sensitivity 73.3%,specificity 75.1%)for PTEN.Conclusions miR-26a-5p suppresses PTEN through targeted inhibition,activating PI3K/AKT/mTOR signaling pathways while impairing DNA repair functions.This cascade leads to accumulated oxidative stress and sperm morphological abnormalities.The combined pattern of elevated seminal plasma exosomal miR-26a-5p expression and reduced PTEN levels demonstrates diagnostic potential for idiopathic teratozoospermia,with its molecular mechanism providing a theoretical foundation for biomarker development.Targeted silencing of miR-26a-5p,either alone or in combination with AKT/mTOR inhibitors and antioxidant therapy,may represent a novel strategy for improving sperm morphology.
