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.

Objective:To assess the long-term outcome of sequential radical surgery after immune combined with targeted therapy for patients with initially unresectable hepatocellular carcinoma (HCC).Methods:Clinical data of 100 patients with initially unresectable HCC undergoing sequential radical surgery after immune combined with targeted therapy at the Faculty of Hepato-Pancreato-Biliary Surgery of Chinese PLA General Hospital from December 2018 to August 2023 were prospectively collected, including 87 males and 13 females, with a median age of 55 (24-73) years. The pre-treatment tumor staging was determined using the China liver cancer staging (CNLC). The efficacy of immune combined with targeted therapy was accessed using the modified response evaluation criteria in solid tumor (mRECIST). The cycles of immune combined with targeted therapy were analyzed. The tumor residual of resected tissue was analyzed through a standard pathological protocol. The prognosis was analyzed using the Kaplan-Meier method.Results:Upon initial diagnosis, there were 46 cases (46.0%) staged CNLC-Ⅲa and 40 (40.0%) staged CNLC-Ⅲb. There were also 14 cases (14.0%) staged CNLC-Ⅰb, Ⅱa, and Ⅱb who underwent immune combined with targeted therapy due to rupture of tumor or insufficient liver remnant. All patients received a median of 5 (3-28) cycles of immune combined with targeted therapy and underwent radical surgery after successful conversion. According to mRECIST, 14 (14.0%) were determined as complete remission, 63 (63.0%) as partial remission, 18 (18.0%) as stable disease, and 5 (5.0%) as disease progression. Of 24 (24.0%) were defined as pathologically complete remission by postoperative pathology. Furthermore, pathological tumor residue was less than 10% in 61 (61.0%) cases and less than 50% in 82 (82.0%) cases. The 1, 3, and 5 year-overall survival rates of patients were 98.0%, 83.1%, and 74.5%, respectively. The 1, 2 and 3 year-recurrence-free survival rates were 67.5%, 54.8%, and 49.6%, respectively.Conclusion:Sequential radical surgery after immune combined with targeted therapy benefits the long-term survival of patients with initially unresectable HCC.

Objective     To investigate the accuracy of 18F-FDG positron emission tomography/computed tomography (PET/CT) combined with CT three-dimensional reconstruction (CT-3D) in the differential diagnosis of benign and malignant pulmonary nodules. Methods     The clinical data of patients who underwent pulmonary nodule surgery in the Department of Thoracic Surgery, Northern Jiangsu People's Hospital from July 2020 to August 2021 were retrospectively analyzed. The preoperative 18F-FDG PET/CT and chest enhanced CT-3D and other imaging data were extracted. The parameters with diagnostic significance were screened by the area under the receiver operating characteristic (ROC) curve (AUC). Three prediction models, including PET/CT prediction model (MOD PET), CT-3D prediction model (MOD CT-3D), and PET/CT combined CT-3D prediction model (MOD combination), were established through binary logistic regression, and the diagnostic performance of the models were validated by ROC curve. Results     A total of 125 patients were enrolled, including 57 males and 68 females, with an average age of 61.16±8.57 years. There were 46 patients with benign nodules, and 79 patients with malignant nodules. A total of 2 PET/CT parameters and 5 CT-3D parameters were extracted. Two PET/CT parameters, SUVmax≥1.5 (AUC=0.688) and abnormal uptake of hilar/mediastinal lymph node metabolism (AUC=0.671), were included in the regression model. Among the CT-3D parameters, CT value histogram peaks (AUC=0.694) and CT-3D morphology (AUC=0.652) were included in the regression model. Finally, the AUC of the MOD PET was verified to be 0.738 [95%CI (0.651, 0.824)], the sensitivity was 74.7%, and the specificity was 60.9%; the AUC of the MOD CT-3D was 0.762 [95%CI (0.677, 0.848)], the sensitivity was 51.9%, and the specificity was 87.0%; the AUC of the MOD combination was 0.857 [95%CI (0.789, 0.925)], the sensitivity was 77.2%, the specificity was 82.6%, and the differences were statistically significant (P<0.001). Conclusion     18F-FDG PET/CT combined with CT-3D can improve the diagnostic performance of pulmonary nodules, and its specificity and sensitivity are better than those of single imaging diagnosis method. The combined prediction model is of great significance for the selection of surgical timing and surgical methods for pulmonary nodules, and provides a theoretical basis for the application of artificial intelligence in the pulmonary nodule diagnosis.

Objective To observe the value of ultrasound radiomics for distinguishing early and middle-late stage endometrial cancer(EC).Methods A total of 294 women with EC were retrospectively enrolled,including 196 in early stage and 98 in middle-late stage.The patients were randomly divided into training set(n=206)and validation set(n=88)at the ratio of 7∶3.Clinical data were compared between different stages,and a clinical model was constructed.Radiomics features were extracted and screened based on ultrasound data,and radiomics models were constructed with logistic regression(LR),random forest(RF),support vector machine(SVM),Gaussian naive Bayes(GNB)and extreme gradient boosting(XGBoost),respectively.Finally,a clinical-radiomics model was constructed.The value of each model for distinguishing early and middle-late stages EC was observed.Results Significant differences of age of consultation,menstrual disorders,abdominal pain and proportion of menopause were found between patients with early and middle-late stage EC(all P＜0.05).Among these 5 radiomics models,RF model had the highest area under the curve(AUC)for distinguishing early and middle-late stage EC.Pairwise comparison of clinical model,RF radiomics model and clinical-RF radiomics model showed that significant differences of AUC were found between each 2 models(all P＜0.05),and clinical-RF radiomics model had the highest AUC.Conclusion Ultrasound radiomics based on RF were helpful for distinguishing early and middle-late stage EC,and better diagnostic efficacy could be obtained through combining with clinical data.

Most patients with primary hepatocellular carcinoma (HCC) are already in advanced stage when they are diagnosed, with a short survival period and an extremely poor prognosis. HCC seriously threatens the life and health of Chinese people. In recent years, breakthroughs have been made in systemic treatment of HCC, especially in immunotherapy represented by immune checkpoint inhibitors, which has broken the single therapy situation of molecular targeted drugs. And the strategy of immunotherapy combined with anti-angiogenic therapy has shown superiority and profoundly changed the treatment strategy of HCC. This article focuses on several hotspots of immune checkpoint inhibitors combined with anti-angiogenic targeted drugs in the perioperative scenario of HCC, and takes stock of the latest research progress of immunotherapy combined with anti-angiogenic drugs regimens in the perioperative application of HCC.
