Objective To construct a discharge preparation plan for patients with head and neck cancer undergo-ing tracheotomy and explore its application effect to provide a reference for improving the at-home self-care ability of tracheostomy patients with head and neck cancer.Methods The discharge preparation plan for patients with head and neck cancer undergoing tracheotomy was constructed through literature analysis and expert consultation.A total of 160 patients with tracheotomy for head and neck cancer who were hospitalized in the Department of Oto-laryngology and Head and Neck Surgery of a tertiary A general hospital in Jinan City,Shandong Province from May 2023 to February 2025 were selected by convenience sampling method as the study subjects,and were divided into an experimental group and a control group by block randomization method,with 80 cases in each group.The ex-perimental group received a discharge preparation plan for patients undergoing tracheotomy for head and neck can-cer,while the control group received routine nursing and health education.Data from admission to 1 month after discharge were collected.The levels of mindfulness awareness,self-care ability,and discharge readiness were compared between 2 groups of patients before and after intervention.Results The constructed discharge preparation plan in-cludes 5 stages(pre-contemplation,contemplation,preparation,action,and maintenance).There were no sample dropouts in either group of patients.The experimental group had higher levels of mindfulness awareness,self-care ability and discharge readiness scores than the control group,and the differences were statistically significant(P＜0.001).Conclusion The discharge preparation plan for patients with head and neck cancer undergoing tra-cheotomy is scientifically reasonable,safe,and feasible,which can effectively improve patients' discharge preparation and mindfulness level,and enhance their self-care ability.

Objective To investigate the causal relationship between circadian rhythm disruption and inflammatory bowel disease(IBD)and the mediating effect of gut microbiota based on Mendelian randomization(MR).Methods Summary statistics of Genome-wide Association Study(GWAS)for circadian rhythm disruption(n=205 527)and IBD(n=214 053)were obtained from IEU OpenGWAS database.Summary statistics of GWAS for the gut microbiota were obtained from the MiBioGen database(n=18 340).Two-sample MR analysis was used to estimate the genetic correlation and causality between circadian rhythm disruption and IBD,and the mediating effect of the gut microbiota was analyzed by two-step MR analysis.Results There was a suggestive causal relationship between circadian rhythm disruption and IBD(odds ratio=1.255,P＜0.05).Rikenellaceae id.967 played a mediating role in the causal chain between them(the mediating effect was-0.028 740).Sensitivity analysis confirmed that the results were not interfered by level pleiotropy and heterogeneity.Conclusion There is a genetic correlation between circadian rhythm disruption and IBD,and gut microbiota may play a mediating role between them.

Objective To develop and validate a prediction model to identify high-risk individuals who are at-risk to develop acute liver injury(ALI)within 180 days in new statin users,and to support early clinical intervention.Methods Data were sourced from the Yinzhou Regional Health Information Platform,covering statin initiators aged 18 years and older from January 1,2010,to October 31,2021.The dataset was divided into a derivation cohort and a temporal validation cohort based on the time of statin initiation.Predictors were selected using LASSO regression,and the model was constructed using the extreme gradient boosting(XGBoost)algorithm combined with cost-sensitive learning.Model performance was evaluated using Brier scores,Harrell's C-index,and calibration curves.Results A total of 126,440 statin initiators were included,with 90,542 in the derivation cohort and 35,898 in the validation cohort.Within 180 days of initial statin use,412(0.33％)patients developed ALI,including 305(0.34％)in the derivation cohort and 107(0.30％)in the validation cohort.The final model incorporated 16 predictors,which included demographic characteristics,lifestyle factors,family history,medical history,statin use,and concomitant medication use.The model demonstrated excellent overall performance[Brier score=0.0043,95％CI(0.0038,0.0049)],discrimination[Harrell's C-index=0.761,95％CI(0.725,0.794)],and calibration in internal validation.In temporal validation,the model also performed well[Brier score=0.0044,95％CI(0.0036,0.0052),Harrell's C-index=0.703,95％CI(0.614,0.781)].Conclusion This study develope and validate a prediction model for ALI in statin users,providing clinicians with a reliable tool for individualized risk assessment.This model can help achieve risk stratification and reduce the occurrence of ALI.

We report a 30-year-old woman who presented with intermittent gross hematuria and left flank pain，and CT revealed a left staghorn stones. The initial percutaneous nephrolithotomy（PCNL）left a 6 mm fragment，and both stone and urine cultures yielded extended-spectrum β-lactamase（ESBL）-producing Escherichia coli. Seven months later，the stone increased to 6 cm and urine culture revealed Proteus mirabilis. Endoscopic combined intrarenal surgery（ECIRS）achieved complete clearance. At 6-month follow-up，the patient remained asymptomatic，culture-negative，and stone-free. This case highlights that small residual fragments after PCNL may rapidly enlarge with secondary urease-producing infection，underscoring the need for early re-intervention and standard follow-up.

Objective To construct and verify a nomogram model for predicting social urinary control recovery in patients undergoing robot-assisted radical prostatectomy (RARP) immediately after extubation. Methods A retrospective analysis was conducted on the clinical data of 64 patients diagnosed with prostate cancer and treated by a single surgeon. The immediate urinary control status of the patients after removal of the catheter was evaluated, and LASSO regression was used for feature screening. Multiple Logistic regression was performed on the selected features to determine independent risk factors and establish a predictive model. And the discriminability, calibration, and clinical practicality of the model were evaluated using receiver operating curve (ROC), Hosmer Lemeshow test and calibration curve, and clinical decision curve (DCA) analysis. Results The variables in the outcome prediction model include D'Amico grading and distance of the levator muscle. The area under the ROC curve (AUC) was 0.742 (95%CI, 0.500 to 0.913, P < 0.001), indicating that the model had good discriminability. The calibration curve indicated that the model had good calibration ability. The DCA curve showed good clinical practicality. Conclusion The clinical predictive model developed inthis study can predict the recovery of immediate social urinary control in patients with RARP after surgery, which can further quantify the probability of achieving immediate social continence.

ObjectiveThe lung mesenchymal stem cells （LMSCs） induced by D-galactose （D-gal） were intervened by Wenfei Huaxian decoction-containing serum to explore the mechanism of Wenfei Huaxian decoction in delaying the senescence of LMSCs through the nicotinamide phosphoribosyltransferase/silent information regulator 1 （NAMPT/SIRT1） signaling pathway. MethodWenfei Huaxian decoction-containing serum was prepared. LMSCs were isolated by gradient density centrifugation， and they were cultured and identified in vitro. The senescence model in vitro was established by stimulating cells via D-gal for 24 h. LMSCs cells were modeled after being treated with different volume fractions （5%， 10%， 20%， 40%， and 80%） of Wenfei Huaxian decoction-containing serum for 24 h， and the cell proliferation level was detected by methyl thiazolyl tetrazolium （MTT） method. The cells were randomly divided into blank serum group， model group， and high， medium， and low dose groups of Wenfei Huaxian decoction-containing serum. Senescence-associated β-galactosidase （SA-β-gal） staining was used to detect the senescence of LMSCs in each group. The content of NAD + was detected by colorimetry. The levels of senescence-associated factors （p16 and p53）， interleukin-6 （IL-6）， and tumor necrosis factor-α （TNF-α） in cell culture supernatant were detected by enzyme-linked immunosorbent assay （ELISA）. Western blot was used to detect the relative expression of senescence-associated proteins and NAMPT/SIRT1 signaling pathway-related proteins. ResultCompared with the blank serum group， the proliferation of LMSCs was significantly inhibited after D-gal stimulation for 24 h （P<0.01）. Compared with the model group， the proliferation of LMSCs could be promoted after intervention with the corresponding Wenfei Huaxian decoction-containing serum （P<0.05， P<0.01）. Compared with the blank serum group， the SA-β-gal staining of LMSCs in the model group after D-gal stimulation was enhanced， and the content of NAD⁺ was increased （P<0.01）. The expression levels of senescence factors p16 and p53， as well as SASP pro-inflammatory factors IL-6 and TNF-α in the cell culture supernatant， were significantly increased （P<0.01）. The expression of senescence-associated proteins p16， p21， and p53 increased （P<0.01）， and the protein expression of NAMPT， SIRT1， peroxisome proliferator-activated receptor γ coactivator 1α （PGC-1α）， and forkhead box family transcription factor O1 （FoxO1） decreased （P<0.01）. Compared with the model group， the SA-β-gal staining of LMSCs in each group of Wenfei Huaxian decoction-containing serum was significantly reduced， and the content of NAD⁺ was decreased （P<0.01）. The senescence factors （p16 and p53） and inflammatory factors （IL-6 and TNF-α） in the cell culture supernatant were significantly decreased （P<0.01）. The expression of senescence-associated proteins （P16， P21， and P53） decreased （P<0.05， P<0.01）. The protein expressions of NAMPT， SIRT1， PGC-1α， and FoxO1 were significantly up-regulated （P<0.05， P<0.01）. ConclusionWenfei Huaxian decoction can alleviate senescence and inflammatory response damage of D-gal-induced LMSCs， and its mechanism may be related to the regulation of the NAMPT/SIRT1 signaling pathway.
