Purpose: The genomic characteristics of uterine sarcomas have not been fully elucidated. This study aimed to explore the genomic landscape of the uterine sarcomas (USs). Materials and Methods: Comprehensive genomic analysis through RNA-sequencing was conducted. Gene fusion, differentially expressed genes (DEGs), signaling pathway enrichment, immune cell infiltration, and prognosis were analyzed. A deep learning model was constructed to predict the survival of US patients. Results: A total of 71 US samples were examined, including 47 endometrial stromal sarcomas (ESS), 18 uterine leiomyosarcomas (uLMS), three adenosarcomas, two carcinosarcomas, and one uterine tumor resembling an ovarian sex-cord tumor. ESS (including high-grade ESS [HGESS] and low-grade ESS [LGESS]) and uLMS showed distinct gene fusion signatures; a novel gene fusion site, MRPS18A–PDC-AS1 could be a potential diagnostic marker for the pathology differential diagnosis of uLMS and ESS; 797 and 477 uterine sarcoma DEGs (uDEGs) were identified in the ESS vs. uLMS and HGESS vs. LGESS groups, respectively. The uDEGs were enriched in multiple pathways. Fifteen genes including LAMB4 were confirmed with prognostic value in USs; immune infiltration analysis revealed the prognositic value of myeloid dendritic cells, plasmacytoid dendritic cells, natural killer cells, macrophage M1, monocytes and hematopoietic stem cells in USs; the deep learning model named Max-Mean Non-Local multi-instance learning (MMN-MIL) showed satisfactory performance in predicting the survival of US patients, with the area under the receiver operating curve curve reached 0.909 and accuracy achieved 0.804. Conclusion USs harbored distinct gene fusion characteristics and gene expression features between HGESS, LGESS, and uLMS. The MMN-MIL model could effectively predict the survival of US patients.

Objective To analyze the nonlinear relationship between hypothermic machine perfusion (HMP) parameters and delayed graft function (DGF) and optimize the construction of a predictive model for DGF. Methods The data of 923 recipients who underwent kidney transplantation from deceased donors were retrospectively analyzed. According to the occurrence of DGF, the recipients were divided into DGF group (n=823) and non-DGF group (n=100). Donor data, HMP parameters and recipient data were analyzed for both groups. The nonlinear relationship between HMP parameters and the occurrence of DGF was explored based on restricted cubic splines (RCS). Over-sampling, under-sampling and balanced sampling were used to address the imbalance in the proportion of DGF to construct logistic regression predictive models. The area under the curve (AUC) of each model was compared in the validation set, and a nomogram model was constructed. Results Donor BMI, cold ischemia time of the donor kidney, and HMP parameters (initial and final pressures, resistance, and perfusion time) were significantly different between the DGF and non-DGF groups (all P<0.05). The RCS analysis revealed a threshold-like nonlinear relationship between HMP parameters and the risk of DGF. Among the models constructed using different sampling methods, the balanced sampling model had the highest AUC. Using this model, a nomogram was constructed to stratify recipients based on risk scores. Recipients in the high-risk group had higher serum creatinine levels at 1, 6, and 12 months after kidney transplantation compared to those in the low-risk group (all P<0.05). Conclusions There is a nonlinear relationship between HMP parameters and the risk of DGF, and the threshold is helpful for organ quality assessment and monitoring of graft function after transplantation. The predictive model for DGF constructed on the base of balanced sampling algorithms helps perioperative decision-making and postoperative graft function monitoring of kidney transplantation.

Therefore, the occurrence, clinical manifestations, diagnosis and treatment strategies of common vascular complications after kidney transplantation, including vascular stenosis, arterial dissection, pseudoaneurysm, vascular rupture and thrombosis were reviewed in this article. In combination with the incidence, diagnosis and treatment of vascular complications after kidney transplantation in the First Affiliated Hospital of Xi'an Jiaotong University, diagnosis and treatment strategies for common vascular complications after kidney transplantation were summarized, aiming to provide reference for clinical diagnosis and treatment of vascular complications after kidney transplantation, lower the incidence of vascular complications, and improve clinical efficacy of kidney transplantation and survival rate of recipients.

[Objective] To analyze the changes of platelet extracellular vesicles (PEVs) content in apheresis at different storage periods, track the PEVs and transfusion efficacy of patients, and explore the mechanism of PEVs in relation to platelet storage damage and transfusion efficacy. [Methods] From November 2022 to April 2024, a total of 85 apheresis platelets samples were collected at Jiading District Blood Station. Flow cytometry was used to detect the content of PEVs on the day of collection and before transfusion. The changes in the content of PEVs stored for 1 to 5 days were observed. Patients with acute leukemia were selected as transfusion recipients, and their content of platelet count and PEVs before transfusion and within 24 hours after transfusion, and the efficacy were tracked to explore the mechanism of PEVs in relation to storage lesion and transfusion efficacy. [Results] The content of PEVs before platelet infusion (8.73±4.84) was significantly higher than that on the day of platelet collection (5.11±3.33), and the difference was statistically significant (P<0.01). The increase in the content of PEVs in storage for 2 to 5 days was 2.55±1.38, 3.49±2.63, 3.86±3.55 and 4.50±3.91, with statistically significant difference (P<0.05). The PEVs content in patients after blood transfusion was positively correlated with that before transfusion and that in apheresis platelet bags during transfusion (P<0.001) A total of 85 cases of apheresis platelet transfusion were conducted, with 61 effective transfusions having a CCI value of (13.43±4.70), and 24 transfusion refractoriness cases having a CCI value of (2.27±3.67), showing a statistically significant difference (P<0.001). The transfusion effectiveness rates for patients receiving different storage periods of apheresis platelets of 2 to 5 days were 88.89%, 68.42%, 68.18% and 57.14% respectively, with corresponding CCI values of 11.18±6.10, 10.43±6.77, 9.53±6.75 and 9.48±8.86, and there was no significant difference between CCI groups (P>0.05). There was no significant correlation between the PEVs content before and after transfusion and the efficacy of CCI (P>0.05). There was no significant correlation between the PEVs content before apheresis platelet transfusion and the efficacy of CCI (P>0.05). [Conclusion] The content of PEVs increased with the prolongation of storage time, which could be used as a potential blood quality evaluation and monitoring index during the storage period, but it was not significantly correlated with the efficacy of CCI in transfusion.
