On the 110th anniversary of the founding of the Chinese Medical Association, I would like to extend my warmest congratulations and high respect. During the past 110 years, the Chinese Medical Association has protected the health of the people in the years of war, and promoted the vigorous development of the medical cause in the new era. The Chinese Medical Association has always been brave in building the tide of medical development, prospering academia and benefiting the people. On this occasion, the author summarized the development process, practice and achievements of the Chinese College of Intraoperative Ultrasound in Hepatobiliary Surgery. Since its establishment, the Chinese College of Intraoperative Ultrasound in Hepatobiliary Surgery has always been committed to promoting the precise and intelligent development of hepatobiliary surgery. It has been constantly deepening its efforts in academic research, technological innovation, personnel training and other aspects, and injecting continuous power into the vigorous deve-lopment of hepatobiliary surgery in China.

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.

Objective:To investigate effective strategies to reduce the high risk of recurrence after allogeneic hematopoietic stem cell transplantation(allo-HSCT)in patients with minimal residual disease(MRD)-positive B-lineage acute lymphoblastic leukemia(B-ALL).Methods:A retrospective analysis was performed for ten B-ALL patients with positive MRD before transplantation at our center from November 2022 to November 2024.There were four male patients and six female patients,with a median age of 30(7-56)years.Of all patients,four received transplantation from unrelated donors,and six received haploidentical transplantation from relatives.All ten patients received blinatumomab(28 μg/day for 14 days for patients≥45 kg;5 μg/m2/day for 14 days for patients<45 kg)and were bridged to the conditioning regimen for allo-HSCT within 7 days.Results:After treatment with blinatumomab,all ten patients achieved the clearance of MRD.After allo-HSCT,100%of the patients achieved donor hematopoietic reconstitution.The median time to neutrophil reconstitution was 12(9-22)days,and the median time to platelet reconstitution was 13.5(9-22)days.As of January 2025,the median observation time was 14(2-26)months;of all patients,two experienced recurrence,and one had positive MRD again,with a recurrence rate of 20%.Among the ten patients,nine survived and one died of disease recurrence.One patient achieved complete re-mission again after chimeric antigen receptor T-cell(CAR-T)therapy following recurrence,and the patient with positive MRD achieved the clearance of MRD again after interleukin-2 treatment;both patients were currently alive.During treatment,one patient developed cytokine release syndrome,one patient was comorbid with SARS-CoV-2 infection,one patient had herpes zoster and viral encephalitis,three patients developed grade Ⅰ-Ⅱ acute graft-versus-host disease,and four patients developed chronic graft-versus-host disease;no transplantation-associated thrombotic microangiopathy was observed.Conclusion:For patients with MRD-positive B-ALL,blinatumomab as a bridge therapy for allo-HSCT can significantly reduce recurrence after transplantation,with fewer complica-tions that are easy to control.Multicenter randomized controlled clinical studies can be performed to further verify its efficacy and safety.

Endometrial cancer is a common malignant tumor in women, and timely diagnosis and treatment are crucial to reduce its mortality. Radiomics is a new technology for quantitative analysis of image features, which has important value for the research and diagnosis of endometrial cancer. This article will retrospectively review the application of radiomics in endometrial cancer from ultrasound, magnetic resonance imaging (MRI), positron emission tomography/computed tomography (PET/CT) and other imaging modalities, as well as the challenges faced, in order to provide more accurate and reliable guidance for clinical diagnosis and treatment.

Objective: To evaluate the safety and efficacy of ABO non-identical platelets with reduced plasma (ABO-NPRP) transfusion in patients with hematological diseases. Methods: A retrospective analysis was conducted on 52 therapeutic doses of apheresis platelets with reduced plasma prepared at Chongqing Blood Center of the Chinese People's Liberation Army. The transfusion efficacy (24 h CCI) and the transfusion adverse reactions of these apheresis platelets were also observed in 35 patients with hematological diseases in First Affiliated Hospital of Army Medical University. Comparisons were made with a control group consisting of patients who received only identical apheresis platelets during the same period. Meanwhile, the effect of ABO-NPRP on the subsequent platelet transfusion efficacy was observed. Results: There was no statistically significant difference in PDW, MPV, and PLCR before and after the preparation of apheresis platelets with reduced plasma (P>0.05), while the difference in platelet count was statistically significant [(2.86±0.34)×10 per therapeutic dose vs (2.46±0.28)×10 per therapeutic dose, P<0.001]; there was no statistically significant difference in the 24 h CCI transfusion efficacy between conventional identical apheresis platelets and ABO-NPRP, with transfusion efficacy rates of 76.60% and 78.85%, respectively (P>0.05); there was no statistically significant difference in platelet transfusion efficacy between the group with ABO-NPRP and the group without ABO-NPRP (completely identical transfusion group), with transfusion efficacy rates of 77.78% and 75.25%, respectively (P>0.05). Conclusion: ABO-NPRP transfusion is safe, effective, demonstrating comparable efficacy to conventional identical transfusion. It can serve as an important complementary strategy to optimize the utilization of blood resources.
