Cultivating innovative medical talents is a key strategy for enhancing a hospital's core competitiveness.Taking Zhejiang Cancer Hospital as a case study,this paper constructs a lifelong training system for innovative medical talents based on the"Triple-Phase Cultivation Framework(three stages,four integrations,five mechanisms)".This system delineates the cultivation cycle in-to three stages aligned with talent development trajectories:the"30s Start-up Phase"(young talents under 35),the"40s Growth Phase"(core professionals under 45),and the"50s Breakthrough Phase"(academic leaders under 50).It implements a four-dimensional cultivation model integrating medicine with research,education,engineering/informatics,and industry.Furthermore,a com-prehensive guarantee mechanism is established,encompassing policies & systems,platform re-sources,project drivers,financial investment,and talent teams.Practice demonstrates that this system has significantly enhanced talent development effectiveness.Over the past five years,the hospital has established 2 academician workstations and recruited 10 academician teams.The annual number of postdoctoral researchers has surged from 4 in 2020 to 58 in 2024.A total of 71 innova-tive talents have been selected across three batches,with 69 recognitions in provincial/ministerial-level talent programs,placing the hospital among the leaders within hospitals directly under the Zhejiang Provincial Health Commission.Notably,the hospital achieved a"zero breakthrough"in in-dependently cultivating national-level talents,including recipients of the National Ten-Thousand Talent Program(Young Top Talents)and the Postdoctoral Innovative Talent Support Program.The"Triple-Phase Cultivation Framework"establishes a replicable paradigm for nurturing innovative medical talents through its full-career-cycle approach,multidisciplinary integration,and systematic support mechanisms,offering valuable insights for talent strategies in specialized cancer hospitals.

Objective To explore the correlations of multimodal ultrasound manifestations of Hashimoto thyroiditis(HT)with normal thyroid function and serum thyroid peroxidase antibody(TPOAb)titer.Methods Data of gray-scale ultrasound,CDFI and shear wave elastography(SWE)of 100 HT patients with normal thyroid function were retrospectively analyzed.According to gray-scale ultrasound manifestations,HT was classified into focal type(type A),nodular-like type(type B),diffuse hypoechoic type(type C)and diffuse hyperechoic type(type D).Meanwhile,based on blood flow distribution shown on CDFI,HT was classified into abundant type,increased type,normal type and sparse type.Correlations of the mean Young's modulus(Emean)of thyroid gland and CDFI classification of HT with serum TPOAb titer were analyzed.Results For all 100 cases,serum TPOAb titer was(270.31±72.63)IU/ml.There were 38 cases of type A,26 cases of type B,20 cases of type C and 16 cases of type D based on gray-scale ultrasound,and 15 cases of abundant type,9 cases of increased type,69 cases of normal type and 7 cases of sparse type based on CDFI,respectively.The Emean of thyroid in all 100 cases was(22.31±7.38)kPa.Significant differences of serum TPOAb titer and thyroid Emean were found among different gray-scale ultrasound HT types(all P＜0.05).Thyroid Emean values of all 100 patients were positively correlated with TPOAb titer(rs=0.702,P=0.037).The thyroid Emean of patients with type A,B,C and D HT were positively correlated with TPOAb titer(rs=0.752,0.823,0.853,0.497,all P＜0.05),while the CDFI types of HT were negative correlated with serum TPOAb titer(rs=-0.746,P=0.035).Conclusion Both thyroid Emean and blood flow signals in HT patients with normal thyroid function were correlated with serum TPOAb titer.

Objective:To analyze and evaluate the application effect of magnetic navigation-guided nasojejunal tube placement in critically ill patients by literature retrieval.Methods:The Chinese databases of CNKI,Wanfang,VIP and Chinese Biomedical Literature Service System were searched,as well as the literature on randomized controlled trials of magneto-guided nasojejunal tube placement in critically ill patients in foreign language databases of PubMed,CINAHL,Cochrane Library,Web of Science,and Embase,the search period was from January 2000 to September 2023.The literature were screened according to the inclusion and exclusion criteria,and the quality of the literature was evaluated.RevMan 5.4.1 software was used to conduct a meta-analysis of the four outcomes in the literature:success rate of placement,time required for successful placement,time to recovery of vital signs,and patient satisfaction.Results:A total of 7 randomized controlled trials of 7 studies were included,including 4 Chinese studies and 3 English studies,involving 682 patients.The success rate of magnetic navigation-guided nasojejunal tube placement was higher than that of bedside blind nasojejunal tube placement,the difference was statistically significant[OR=4.78,95%CI(2.16～10.58),P<0.0001].The time required for magnetic navigation guided nasojejunal tube placement was less than that of the bedside blind nasojejunal tube placemen,the difference was statistically significant[MD=-12.91,95%CI(-22.93～-2.90,P<0.00001].The time required for recovery of vital signs in patients with magnetic navigation guided nasojejunal tube placement was less than that of the bedside blind nasojejunal tube placemen,the difference was statistically significant[MD=-9.11,95%CI(-12.09～-6.13,P<0.00001].The satisfaction of patients with the magnetic navigation-guided nasojejunal tube placement was higher than that of patients with the bedside blind nasojejunal tube placement,the difference was statistically significant[OR=11.61,95%CI(3.96～34.01),P<0.00001].Conclusion:Compared with bedside blind nasojejunal tube placement,magnetic navigation-guided nasojejunal tube placement can significantly improve the success rate of nasojejunal tube placement in critically ill patients,reduce the time required for successful nasojejunal tube placement,reduce the recovery time of patients'vital signs,and improve patient satisfaction.

Objective:To evaluate the clinical efficacy of allogeneic hematopoietic stem cell transplantation（allo-HSCT）in children with severe aplastic anemia（SAA）.Methods:Twenty-seven cases with SAA who had been treated with allo-HSCT from January 2020 to December 2022 were retrospectively analyzed and reviewed.Results:（1）A total of 27 SAA patients were enrolled，including 18 males and 9 females，with a median age of 8 (2-15) years.There were 20 cases of SAA-Ⅰ type,7 cases of SAA-Ⅱ type.Based upon donor sources，three cases of matched sibling donors hematopoietic stem cell transplantation,and 24 cases of haploidentical hematopoietic stem cell transplantation were adopted.（2）Hematopoietic reconstruction was achieved in all 27 cases.The median implantation time of neutrophils and platelets was 10（9-20）days and 12（7-26）days respectively.The cumulative incidence of acute graft-versus-host disease（GVHD）was 66.67%（18/27）.The incidence of grade Ⅰ-Ⅱ was 55.56%（15/27）and that of grade Ⅲ-Ⅳ was 11.11%（3/27）.The incidence of chronic GVHD was 7.41%（2/27）.Transplant-associated thrombotic microangiopathy (TA-TMA) occurred in 7.41%（2/27）patients,cytomegalovirus viremia in 62.96%（17/27）patients,epstein-barr virus infection in 33.33%（9/27）patients,and 14.81%（4/27）patients progressed to post-transplant lymphoproliferative disorder (PTLD).（3）The median follow-up time was 12 (2-28) months.The overall survival rate was 96.29%.Twenty-six patients survived,and one patient died due to multiple complications of severe acute GVHD,TA-TMA,cytomegalovirus infection,PTLD and secondary epilepsy.Conclusion:Allo-HSCT is an effective therapy for SAA in children.The effective rate of this research is 96.29%.Acute GVHD is still the key to therapy.The incidence rate of acute GVHD is 66.67% in this study.The blood incompatibility of donor and recipient may affect the incidence of GVHD.The intensity of GVHD prevention should be reduced after HLA-matched sibling donor-hematopoietic stem cell transplantation so as to avoid the complications of virus recurrence and PTLD.

Periodontitis is an inflammatory disease caused by bacterial infection directly, and the dysregulation of host immune-inflammatory response finally destroys periodontal tissues. Current treatment strategies for periodontitis mainly involve mechanical scaling/root planing (SRP), surgical procedures, and systemic or localized delivery of antimicrobial agents. However, SRP or surgical treatment alone has unsatisfactory long-term effects and is easy to relapse. In addition, the existing drugs for local periodontal therapy do not stay in the periodontal pocket long enough and have difficulties in maintaining a steady, effective concentration to obtain a therapeutic effect, and continuous administration always causes drug resistance. Many recent studies have shown that adding bio-functional materials and drug delivery systems upregulates the therapeutic effectiveness of periodontitis. This review focuses on the role of biomaterials in periodontitis treatment and presents an overview of antibacterial therapy, host modulatory therapy, periodontal regeneration, and multifunctional regulation of periodontitis therapy. Biomaterials provide advanced approaches for periodontal therapy, and it is foreseeable that further understanding and applications of biomaterials will promote the development of periodontal therapy.

Objective To express UL148 RNA of human cytomegalovirus (HCMV) clinical strains in vitro and to study its functions. Methods Urine of a newborn with HCMV infection was inocula-ted into human embryo lung cells. HCMV clinical strain was isolated and identified by multiplex PCR. UL148 gene was amplified and cloned into pGEM-T-Easy plasmid after double enzyme digestion. A recombi-nant plasmid was constructed and located at the downstream of the T7 promoter. The recombinant plasmid was identified by electrophoresis of the recombinant plasmid,PCR product and double enzyme product. Se-quencing analysis was used for final confirmation. UL148 was transcribed into RNA by 32P labeling. Post-translational modification sites were analyzed by bioinformatics method based on UL148 sequence characteris-tics. Results The clinical strain of HCMV was obtained in vitro. Electrophoresis and sequencing analysis confirmed the successful construction of the recombinant plasmid. UL148 RNA was transcribed in vitro by T7RNA polymerase. Post-translational modification sites showed that UL148 gene contained one cell adhe-sion sequence, one legume lectins beta-chain signature, two N-myristoylation sites, one casein kinase Ⅱphosphorylation site,seven protein kinase C phosphorylation sitse, one cAMP/cGMP-dependent protein ki-nase phosphorylation site, two N-glycosylation sites and one transmembrane region. Conclusion UL148 gene might encode a viral adhesion molecule involving in the signal transduction in host cells.
