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 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 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 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.

Objective To explore the effect and mechanism of Sechang Zhixie Powder(SCZXS)on mice with acute diarrhea caused by castor oil.Methods The mice were randomly divided into blank control group,model control group,montmorillonite powder group(1.4 g·kg-1),SCZXS-L group(0.9 g·kg-1),SCZXS-M group(1.8 g·kg-1)and SCZXS-H group(3.6 g·kg-1),10 mice in each group.After continuous administration of 7 days,the acute diarrhea model of mice was prepared by oral administration of castor oil(0.01 mL·g-1).The diarrhea of mice was observed within 4 hours of castor oil administration,and the rate of loose stool,degree of loose stool,and diarrhea index were calculated;the levels of DAO,D-LDH,VIP,and SS in the colon were determined by enzyme-linked immunosorbent assay;The morphological changes in the colon tissue of mice were observed after HE staining and the thicknesses of the mucosal and muscular layers of the colon were quantified;AB-PAS staining was performed to observe the effect on mucin in the colon;and the expression of AQP3,Occludin,and ZO-1 in the colon were quantified by immunohistochemistry.Results Compared with the model control group,the rate of loose stool,degree of loose stool,and diarrhea index of the mice in the SCZXS groups tended to decrease,but the difference was not statistically significant.Compared with the model control group,the flat luminal surface of the mice in the SCZXS-M and SCZXS-H group were significantly thickened(P<0.01),and the amount of VIP in the colon was significantly decreased(P<0.05,P<0.01),and that of DAO in the colon was significantly decreased(P<0.01),Occludin and ZO-1 expression were significantly increased(P<0.01),the mucin area ratio was significantly increased(P<0.05)in the SCZXS-M group,and AQP3 expression was significantly increased(P<0.05)in the SCZXS groups.Conclusions SCZXS can improve acute diarrhea induced by castor oil in mice.and its mechanism may be related to the regulation of gastrointestinal hormones and AQP3.In addition,SCZXS improves intestinal damage caused by diarrhea and protects the intestinal barrier.
