Objective To investigate the relationships of the expression levels of BUB1 mitotic checkpoint serine/threonine kinase B(BUB1B)and kinesin family member 11(KIF11)in peripher-al blood with postoperative recurrence in non-muscle-invasive bladder cancer(NMIBC)patients trea-ted with transurethral resection of bladder tumor(TURBT).Methods A retrospective case-control study design was employed.A total of 188 NMIBC patients who received standard TURBT treatment in the 215th Hospital of Shaanxi Nuclear Industry during initial visit from January 2019 to December 2021 were selected as research objects.Patients were followed up for 36 months and divided into re-currence group(n=68)and non-recurrence group(n=120)based on pathological examination re-sults.Additionally,50 healthy individuals who underwent physical examinations during the same period were selected as control group.The levels of BUB1B mRNA and KIF11 mRNA in peripheral blood were compared among the recurrence group,non-recurrence group,and control group.Clinical data were compared between the recurrence and non-recurrence groups.Cox proportional hazards regression models were used to analyze the postoperative follow-up data of NMIBC patients with TURBT.Kaplan-Meier plots were drawn to assess the proportional hazards assumption(PH assumption)of the Cox model.The predictive efficacy of various indicators for postoperative recurrence in NMIBC patients was eval-uated using receiver operating characteristic(ROC)curve.Results The levels of BUB1B mRNA and KIF11 mRNA in peripheral blood in the control group,non-recurrence group,and recurrence group sucessively increased(P＜0.001).The recurrence group had a significantly higher number of patients with pathological T1 staging and multiple tumors compared to the non-recurrence group(P＜0.05).The Kaplan-Meier curves for the number of tumors,pathological staging,BUB1B mRNA,and KIF11 mRNA levels were generally parallel to recurrence rates between the two groups,meeting PH assumption.Multiple tumors,pathological T1 staging,BUB1B mRNA,and KIF11 mRNA levels were independent influencing factors for recurrence in NMIBC patients after TURBT treatment(P＜0.05).ROC curve analysis showed that the areas under the curves(AUCs)for predicting postoper-ative recurrence in NMIBC patients by multiple tumors,pathological T1 staging,BUB1B mRNA,and KIF11 mRNA levels were 0.674,0.746,0.610 and 0.642,respectively.The combined pre-diction using these indicators yielded an AUC of 0.826(95％CI,0.767 to 0.884),with a sensitiv-ity of 86.80％and a specificity of 75.30％,indicating good predictive efficacy.Conclusion Ele-vated levels of BUB1B mRNA and KIF11 mRNA in peripheral blood are significantly associated with postoperative recurrence in NMIBC patients after TURBT and serve as independent risk factors for recurrence.As non-invasive biomarkers,BUB1B mRNA and KIF11 mRNA in peripheral blood com-bined with clinical parameters can significantly improve the predictive efficacy of postoperative recur-rence,providing a new strategy for individualized monitoring.

Objective To preliminarily describe the current situation of chronic disease drug continuity between community hospitals and the Affiliated Hospital of Qingdao University in the medical alliance,to explore the key points for further improving the connection between upper and lower-level hospitals in the medical alliance,and to improve the drug supply guarantee and the ability of pharmaceutical services of primary medical institutions.Methods The nine community hospitals within the medical alliance centered on the Affiliated Hospital of Qingdao University were taken as the research subjects to investigate the medication continuity between the community hospitals and the core hospital in terms of cardiovascular diseases,diabetes,and respiratory system diseases before and after the medical alliance.Results Before the integration of medical alliances,the drug linkage rate for cardiovascular diseases,diabetes,and respiratory system diseases in community hospitals and core hospitals was relatively low.After the integration of medical alliances,the average drug linkage rate for the three chronic diseases significantly increased,all exceeding 60%.At the same time,the drug catalog in community hospitals was streamlined,reducing the phenomenon of one drug having multiple specifications.There is a significant difference in the number of drug varieties provided by different community hospitals for the three chronic diseases.Conclusion The medical alliance with the Affiliated Hospital of Qingdao University as the core promotes the up-down linkage of drug treatment in community hospitals,simplifies the drug catalog of primary medical structure,and facilitates the treatment and prescription of chronic patients.

DiGeorge(DGS)syndrome is an autosomal dominant disorder caused by 22q11.2 microdeletions,most patients developed the disease in childhood.22q11.2 deletion syndrome,and the mutation types are dominated by haploid deletion of this gene.We report a young patient with hypoparathyroidism(parathyroidism)induced by DGS syndrome combined with hypocalcemic heart failure.Genetic testing revealed pathogenic copy number variants associated with the clinical phenotype of the subject.About 2 674 kb of deletion variation was detected at q11.21 position on chromosome 22,which contained the TBX1 gene and was a pathogenic mutation.This paper discusses the clinical features,pathogenesis and current treatment of DGS,and emphasizes the importance of early screening,early diagnosis and treatment,and regular follow-up of heart failure,aiming to enhance the awareness of clinicians and geneticists on DGS syndrome.

As an important support for hospital operations,hospital logistic maintenance services suffer from pain points such as low efficiency and passive maintenance.The fundamental reason is the lack of a closed-loop mechanism.Based on the closed-loop theory and combined with mathematical modeling,this paper constructs a quality control system for logistic mainte-nance services and proposes a four-stage management process:In the planning stage,optimization goals and constraints are clari-fied.In the design stage,a comprehensive optimization model is established to minimize response time deviation and total mainte-nance costs while maximizing the one-time repair rate.In the execution stage,a maintenance task allocation matrix is generated based on the model solution to optimize resource scheduling.In the inspection stage,RTD,FFR,and QMS are introduced to quantitatively evaluate service performance.In the improvement stage,problem feedback is addressed,and model parameters are adjusted to form a closed loop.Hospital A is used as a practical case study,and the application effect of the quality control sys-tem is verified through analysis of its maintenance data.The quality control system has significant effects on optimizing the re-sponse efficiency,stability,and resource utilization of logistic maintenance services,providing a practical reference for other medical institutions.
