In proton therapy,prompt gamma-ray imaging is considered as one of the most promising methods for assessing proton beam range.Prompt gamma-ray imaging detector evaluates the proton beam range based on the prompt gamma-ray distribution obtained by the prompt gamma-ray imaging system,which enables high-precision measurement of the proton beam range.Herein a proton beam range verification algorithm is designed for the newly developed prototype of the range verification detector(pixelated prompt gamma-ray imaging detector),which verifies the range estimation accuracy of the prototype for different phantoms and different energies of homogeneous media through Monte Carlo simulation.The results show that the accuracy of the proton beam range verification algorithm is within 0.5 mm of the safety margin error of the Bragg peak,and the measurement accuracy is significantly improved with the increase of the number of protons,indicating that the prototype algorithm is feasible for proton beam range verification.

Objective To investigate the biological function of the proprotein convertase subtilisin/kexin type 9(PCSK9)in prostate cancer(PCa)and its effect on ferroptosis sensitivity Methods Bioinformatics was used to analyze the relationship between the expression of PCSK9 and the prognosis of prostate cancer.The expression of PCSK9 in PCa cell lines were detected using RT-qPCR.PCa cells with PCSK9 knockdown were constructed using siRNA,and the The effect of PCSK9 on cell proliferation,migration,and invasion were detected using CCK-8 assays and Transwell assays.The Cancer Therapeutics Response Portal(CTRP)was employed to investigate the correlation between PCSK9 and ferroptosis drug sensitivity,and PCa cells with PCSK9 knockdown were treated with the ferroptosis inducer(RSL3)to detect the sensitivity to ferroptosis.Results Bioinformatics showed low expression of PCSK9 had longer disease specific survival(P<0.05).The results of the in vitro experiments showed that PCSK9 knockdown significantly inhibited the proliferation,migration,and invasion of PCa cells(P<0.001).Furthermore,CTRP analysis showed that cellular sensitivity to ferroptosis inducers correlated with the expression level of PCSK9.PCSK9 knockdown cells exhibited higher sensitivity to the ferroptosis inducer RSL3.Conclusion Knockdown of PCSK9 inhibits the proliferation,migration,and invasion of PCa cells,and increases the sensitivity of cells to ferroptosis inducers.PCSK9 may provide new insights for the treatment of PCa.

Based on the development of implant technology and the increasing demand for implant occlusion reconstruction,this paper focuses on the five subanatomical characteristics and clinical treatment of the teeth,alveolar process,jaw,temporomandibu-lar joint,and mucosal tissue morphology in the implant area,in order to provide a reference for dental implant occlusal reconstruc-tion in patients with jaw fracture and dentition defect.

Objective To summarize the clinical experience of using 3D planar guide plate combined with bundle diameter technology for extracorporeal pre-fenestration in treating complex thoracoabdominal aortic diseases.Methods The clinical data of 31 patients with complex thoracoabdominal aortic diseases,who were treated with 3D planar guide plate combined with bundle diameter technology of extracorporeal pre-fenestration at the First Affiliated Hospital of Soochow University of China from January 2017 to February 2024,were retrospectively analyzed.The patients' preoperative thin-layer chest and abdominal vascular CTA data were imported into specialized software and to create a 3D planar guide plate.Under the guidance of 3D planar guide plate technology,precise extracorporeal pre-fenestration of aortic covered stent was performed,and combined with bundle diameter technology the endovascular repair of complex thoracoabdominal aortic disease was accomplished.Results Successful operation was accomplished in all patients,and two patients had failed visceral artery reconstruction surgery.The median follow-up time was 55 months,with a technical success rate of 97.6％.The postoperative follow-up blood flow patency rate was 100％,and the phase Ⅰ patency rate of branch arteries was 98％.Three patients experienced internal leakage after surgery,and none of them developed paraplegia or died during the perioperative period.Conclusion In treating complex thoracoabdominal aortic diseases,the use of 3D planar guide plate combined with bundle diameter technology of extracorporeal pre-fenestration is simple,safe and effective,with good short-term therapeutic effect,although its long-term efficacy need to be further investigated.

Periodontal disease is a chronic infectious condition mediated by dental plaque biofilms, characterized by the destruction of soft and hard tissues. Metal-organic frameworks (MOFs), a class of porous materials formed through the self-assembly of metal ions and organic ligands via coordination bonds, exhibit high specific surface areas, tunable pore structures, and multifunctionality. In recent years, MOFs have gained significant attentions in biomedical applications and show potential for periodontal therapy. This article reviews the latest research advances in MOFs for antibacterial therapy, drug delivery, and tissue regeneration, systematically analyzes their mechanisms, application potential, and translational challenges, and furtherly discusses future directions in the era of precision medicine.

Objective:To summarize the best available evidence for exercise interventions in patients with systemic lupus erythematosus (SLE) .Methods:The PIPOST model from the Joanna Briggs Institute (JBI) Centre for Evidence-Based Healthcare in Australia was used to construct the evidence-based nursing question. A top-down approach based on the "6S" evidence pyramid model was employed to search for relevant evidence, including clinical guidelines, consensus statements, systematic reviews, best practices, and evidence summaries. The search was conducted across BMJ Best Practice, UpToDate, guideline repositories, professional association websites, and Chinese and international databases. Eligible literature was screened for quality assessment, and high-quality evidence was extracted. The search timeframe covered publications from database inception to June 15, 2024.Results:A total of 15 studies were included, comprising 1 clinical decision-making article, 3 guidelines, 6 systematic reviews, and 5 randomized controlled trials. A total of 25 evidence statements were synthesized across 6 key aspects: exercise principles, exercise assessment, exercise modalities, exercise intensity, exercise frequency and duration, and exercise monitoring.Conclusions:The best evidence summarized in this study provides a valuable reference for clinical healthcare professionals implementing exercise interventions for patients with systemic lupus erythematosus.
