Objective To assess the potential role of disulfidptosis-related genes (DRGs) in pan-cancer on prognosis and immunity on the basis of bioinformatics approaches. Methods Pan-cancer RNA-seq data, mutation profiles, clinical information, TMB, MSI, stemness scores, and tumor and immune microenvironment data contained in TCGA and various open-source online databases, and multi-group R-language algorithms were used for comprehensive analysis. The expression levels of DRGs at the cellular level were experimentally validated using qPCR. Results LRPPRC, NCKAP1, NDUFS1, and NUBPL had a better prognosis in renal clear cell carcinoma (P<0.001), whereas SLC7A11, NCKAP1, and SLC3A2 had a worse prognosis in hepatocellular carcinoma (P<0.001). TME analysis showed that LRPPRC was negatively correlated with immune cells, stromal cells, and estimated scores in all tumor types. TMB analysis revealed the potential research value of DRGs for PD-1/PD-L1 therapy in pan-cancer. Drug sensitivity analysis showed that SLC7A11 (r=0.454), SLC3A2 (r=0.366), and NCKAP1 (r=0.455) were significantly associated with Kahalide F (P<0.01). Experimental validation demonstrated the overall higher expression levels of GYS1 and NCKAP1 than normal cells in lung adenocarcinoma, colon adenocarcinoma, esophageal squamous carcinoma, and hepatocellular carcinoma (P<0.05). Conclusion Pan-cancer analysis of DRGs indicates that DRGs may serve as important biomarkers for the diagnosis and prognosis of renal clear-cell carcinoma, lung adenocarcinoma, and hepatocellular carcinoma.

After continuous development and improvement, lung transplantation has become the preferred means to treat a variety of benign end-stage lung diseases. However, the field of lung transplantation still faces many challenges, including shortage of donor resources, preservation and maintenance of donor lungs, and postoperative complications. Lung tissue samples removed after lung transplantation are excellent clinical resources for the study of benign end-stage lung disease and perioperative complications of lung transplantation. However, at present, the collection, storage and utilization of tissue samples after lung transplantation are limited to a single study, and unified technical specifications have not been formed. Based on the construction plan of the biobank for lung transplantation in the First Affiliated Hospital of Xi'an Jiaotong University, this study reviewed the practical experience in the collection, storage and utilization of lung transplant tissue samples in the aspects of ethical review, staffing, collection process, storage method, quality control and efficient utilization, in order to provide references for lung transplant related research.

Mechanical thrombectomy,which improves the successful vascular recanalization rate and neurological functional prognosis in patients with acute ischemic stroke(AIS)caused by anterior circulation large vessel occlusion,has become one of the primary therapeutic strategies.Among the pharmacologic adjuvant therapies for mechanical thrombectomy,tirofiban(a platelet glycoprotein Ⅱ b/Ⅲ a receptor antagonist)has attracted significant attention due to its antithrombotic mechanism.This article summarized the research progress of tirofiban in the mechanical thrombectomy treatment of AIS patients from the perspectives of pharmacological mechanisms,administration timing,selection of eligible populations,and dosage regimens.It also analyzed the clinical application value and existing controversies of tirofiban,aiming to provide a scientific basis for optimizing the AIS treatment system.

Objective:To explore the anal function and postoperative complications of 2-stage Turnbull-Cutait pull-through coloanal anastomosis (TCA) for low rectal cancer.Methods:Patients undergoing radical rectal cancer resection from Feb 2023 to Nov 2024 in the First Hospital of Jilin University were divided into the TCA surgery group and the low anterior resection combined with prophylactic stoma (LAR) surgery group.Results:Among the 102 patients, there were 50 cases in the TCA group and 52 cases in the LAR group. In the single-arm analysis of the TCA group, the overall complication rate was 44%. The incidence rates of severe LARS at 1 month, 3 months, and 6 months after surgery were 97%, 77%, and 64% respectively. There was no significant difference in the complication rate within 30 days after surgery between the two groups,(44% vs. 38%, χ2=0.135, P>0.05). There was no significant difference in the incidence rate of severe LARS between the TCA group and the LAR group (77% vs. 69%, χ2=0.202, P>0.05), and there was not significant difference in the incidence rate of severe LARS between the two groups at the 6th month after surgery,(64% vs. 48%, χ2=1.132, P>0.05). Conclusion:In patients who underwent TCA surgery, the LARS symptoms gradually decreased over time. Compared with patients undergoing low anterior resection and stoma reversal, there were no significant differences in complications within 30 days after surgery and LARS symptoms within half a year.

Objective:To analyze the spatiotemporal correlation between the surveillance data of influenza in students reported by medical institutions and school absenteeism due to illness, and evaluate the application of Bayesian Structural Time Series model (BSTS) in the prediction of school influenza epidemic.Methods:A total of 13 schools in Dapeng new district of Shenzhen were selected. The incidence data of influenza in schools in Shenzhen from January 1, 2015 to December 31, 2019 were collected from China Disease Control and Prevention Information System and the illness related school absentence data during this period were collected from Shenzhen Student Health Surveillance System, and the spatiotemporal correlation between the data from two systems was analyzed and compared. BSTS was used to make long-term predictions of the monthly incidence of influenza in students in 2019 and short-term predictions of the weekly incidence of influenza in week 1-8 and week 45-52 of 2019 by using the data from two systems.Results:There was a temporal correlation between the data from China Disease Control and Prevention Information System and the data from Shenzhen Student Health Surveillance System ( r=0.93, P<0.001), and the lag of the former one was 1 day ( r=0.73, P<0.001). Influenza outbreaks were randomly distributed in different schools in Shenzhen, and there was no spatial correlation. The root mean square error ( RMSE) and mean absolute error ( MAE) were 0.35 and 0.28, respectively, in the long-term prediction, and the RMSE was 0.33 and 0.34, and the MAE was 0.26 and 0.28, respectively, in the short-term predictions of week 1-8 and week 45-52 of 2019, respectively, showing good prediction accuracy and fitting effect. Conclusion:By analyzing the data from China Disease Control and Prevention Information System and Shenzhen Student Health Surveillance System with BSTS, the dynamics of the school influenza epidemic can be accurately predicted, and effective technical support can be provided for the early warning and prevention and control of influenza epidemic.
