Protein arginine methyltransferase 5 (PRMT5) exhibits elevated expression levels in a variety of cancers and has emerged as a critical target for cancer therapy in recent years. However, first-generation PRMT5 inhibitors have exhibited inadequate selectivity, leading to significant hematological toxicity, thus limiting their clinical utility. The second-generation PRMT5 inhibitors have shown marked improvement in safety and efficacy by selectively targeting MTAP-null tumor cells without impacting normal cells. This review systematically summarizes the biological and functional roles of PRMT5 in MTAP-deficient tumor cells, and comprehensively analyzes the research and development process, molecular binding mechanisms, and the latest advancements in clinical trials of the five second-generation PRMT5 inhibitors currently under investigation, aiming to provide valuable insights for further in-depth studies in this field.

[Objective] To analyze the loss rate of platelet donors and evaluate the strategies for establishing a platelet donor bank. [Methods] A total of 1 443 donors who joined the HLA and HPA gene donor bank for platelets in Henan Province from 2018 to 2020 were included in this study. Data on the total number of apheresis platelet donations, annual donation frequency, age at enrollment, donation habits (including the number of platelets donated per session and whether they had previously donated whole blood), and enrollment location were collected from the platelet donor information management system. Donor loss was determined based on the date of their last donation. The loss rates of different groups under various conditions were compared to assess the enrollment strategies. [Results] By the time the platelet bank was officially operational in 2022, 421 donors had been lost, resulting in an loss rate of 29% (421/1 443). By the end of 2023, the overall cumulative loss rate reached 52% (746/1 443). The loss rate was lower than the overall level in groups meeting any of the following conditions: total apheresis platelet donations exceeding 50, annual donation frequency of 10 or more, age at enrollment of 40 years or older, donation of more than a single therapeutic dose per session, or a history of whole blood donation two or more times. Additionally, loss rates varied across different enrollment locations, with higher enrollment numbers generally associated with higher loss rates. [Conclusion] Through a comprehensive analysis of donor loss, our center has adjusted its strategies for establishing the donor pool. These findings also provide valuable insights for other blood collection and supply institutions in building platelet donor banks.

Objective:To build the three different risk prediction models for peripherally inserted central catheter (PICC) -associated thrombosis based on machine learning algorithm, and compare the performance of the models, so as to provide a basis for evaluating and preventing PICC-associated thrombosis.Methods:The PICC-associated Thrombasis Risk Factor Questionnaire was developed based on the best evidence and expert consultation. From January 2016 to October 2020, convenience sampling was used to select 626 patients with PICC in the Affiliated Hospital of Jiangsu University as the research object to collect clinical data. Based on machine learning algorithms, Support Vector Machine (SVM) , XGBoost and Logistic regression methods were used to construct three different PICC-associated thrombosis risk prediction models, which were evaluated and compared.. Model evaluation indicators included Matthews correlation coefficient ( MCC) , F1 value, area under the receiver operating characteristic curve ( AUC) and Brier score. Results:A total of 30 variables were included, and the predictors included four aspects, namely, demographic data of patients, patient condition, treatment factors, and catheter-related factors. For the model verified on the test set, the Logistic regression prediction model had lower scores than the XGBoost and SVM prediction models in terms of MCC and F1 values. On AUC, the Logistic regression prediction model score was equal to SVM and smaller than XGBoost. On Brier, the Logistic regression prediction model scored higher than the XGBoost and SVM prediction models. Conclusions:The performance of the prediction model based on the machine learning algorithm XGBoost and SVM is superior to the traditional Logistic regression model in terms of sensitivity and accuracy. Thrombotic predictors can help guide medical and nursing staff to identify high-risk patients and reduce the incidence of PICC-associated thrombosis.

Objective:To explore the clinical features of acute diquat (DQ) poisoning, and further improve the awareness of acute DQ poisoning.Methods:A retrospective analysis was performed on the clinical data of patients with acute DQ poisoning diagnosed in the emergency department of the Second Hospital of Hebei Medical University from January 1, 2019 to December 31, 2021. The clinical data included age, gender, exposure routes, presence of pesticides (drugs) mixture poisoning, dosage of poison, the time from taking poisoning to admitting in the emergency department, clinical manifestations, laboratory data, treatment, hospital days, prognosis and survival days.Results:The number of cases who firstly complained of acute DQ poisoning in the past three years were 19 cases in 2019, 28 cases in 2020, and 51 cases in 2021. A total of 12 patients were excluded due to being diagnosed paraquat (PQ) poisoning by toxicology detection. Finally, 86 cases of acute DQ poisoning were included, including 80 cases of oral DQ poisoning, 1 case of intramuscular injection, 1 case of binocular contact and 4 cases of dermal exposure. In 80 cases of oral DQ poisoning, there were 70 cases of diquat poisoning alone (42 cases survived, 28 cases died) and 10 cases of pesticide mixture poisoning (6 cases survived, 4 cases died). The time from oral poisoning to admitting in the emergency department was 0.5-96.0 hours, with an average of (8.6±5.8) hours. The time of intramuscular injection poisoning to admitting in the emergency department was 3 hours. The time of dermal exposure to admitting in the emergency department was relatively long, with an average of 66.1 hours. The time from oral simple DQ poisoning to death was 12.0-108.0 hours, and the time from oral mixed DQ poisoning to death was 24.0-576.0 hours. A total of 70 patients with oral diquat poisoning alone presented various degrees of multiple organ injuries. All patients presented gastrointestinal symptoms such as nausea and vomiting. Renal injury and central nervous system injury were the most significant and closely related to the prognosis.Conclusions:Acute oral DQ poisoning can cause to multiple organ injuries, and the clinical manifestations are related to the dose of the poison. In severe cases, acute renal failure and refractory circulatory failure occur within 24 hours after poisoning, and severe central nervous system injury with disturbance of consciousness as the primary manifestation occurs within 36 hours, followed by multiple organ failure until death.

Novel endogenous lipid-mediated molecules including lipoxins, resolvins, protectins, and maresin families are discovered recently and are collectively called specialized proresolving lipid mediators (SPMs). SPMs have the potential to promote the resolution of inflammation, the elimination of pathogen, and the restoration of homeostasis.Meanwhile, SPMs also have the function of apoptosis inhibition, wound healing, and neuroprotection.SPMs play an important role in the treatment of many eye diseases, such as corneal inflammatory diseases, dry eye, uveitis, retinal and choroidal neovascularization diseases, etc.In this article, the mechanisms involving the role of SPMs in the occurrence and progress of eye diseases were reviewed to provide a general new basis for the future development of new ophthalmic drugs.

Background and Objectives: Stroke mimics are medical conditions producing stroke-like symptoms but eventually get diagnosed as non-stroke diseases. Epileptic seizure is a common type of stroke mimic. The purpose of this study is to investigate the application of emergency multimodal computed tomography (CT) in the diagnosis of epileptic seizure. Methods: We retrospectively reviewed the case group of patients with suspected stroke in the emergency stroke care service of the First Affiliated Hospital of Suzhou University from September 2017 to October 2019. We included those who underwent multimodal CT, including non-contrasted cranial CT, CT perfusion with CT angiography, and were ultimately diagnosed as epileptic seizures. Ten patients with acute anterior circulation ischemic stroke were assigned as controls. Results: A total of five cases met the inclusion criteria. Multimodal CT was completed within 2.25 to 3.50h from symptom onset. On CT perfusion, hyperperfusion was shown in four cases and slightly increased perfusion in one case with epileptic seizures. Cerebral blood flow and cerebral blood volume were significantly increased, while time to peak and mean transit time decreased in the regions of interest of the epileptic hemisphere when compared to either the non-affected hemisphere or the ischemic area in the control group (P<0.05). The abnormal perfusion areas did not follow vascular territory supply and CT angiography did not show vessel occlusion in the case group. Conclusion: Emergency multimodal CT could be used effectively to differentiate epileptic seizure from stroke.

BACKGROUND: Primary lung cancer and metastatic lung cancer are common malignant tumors of the lung and are the main cause of cancer-related death. Advanced lung cancer and lung metastatic cancer are mainly treated by systemic therapy, and local treatment is also an effective treatment for the refractory or recurrent lesions in the lungs after systemic treatment. ¹²⁵I radioactive particle implantation, as an efficient conformal radiotherapy, has a certain control effect on localized lung cancer. The purpose of this study was to investigate the clinical efficacy and safety of computed tomography (CT) guided percutaneous puncture of lung tissue with ¹²⁵I radioactive particle implantation in the treatment of advanced lung cancer and lung metastatic cancer. METHODS: Continuouslycollectedthe clinical and pathological data of 105 patients with advanced lung cancer and metastatic lung cancer treated by ¹²⁵I radioactive seed implantation in the Department of Thoracic Surgery, First Affiliated Hospital of Zhejiang University School of Medicine from January 1, 2014 to November 30, 2018. The patients were followed until March, 2019. The clinical efficacy and complications of seedimplantation were analyzed. RESULTS: A total of 105 patients were included in the study, 78 patients with advanced lung cancer and 27 patients with lung metastases. The median survival time after seed therapy was 395 days. The 1-year survival rate was about 78.1%, and the 2-year survival rate was about 56.1%. Seed implantation for advanced lung cancer is equivalent to lung metastasis. Seed combined with radiofrequency ablation, microwave ablation, and chemotherapy did not improve seed treatment. However, particle combined with external radiation therapy has a significant survival disadvantage compared with simple seed therapy. CONCLUSIONS The CT-guided ¹²⁵I radioactive seed implantation has controllable complications and can be used as a safe and effective treatment for advanced lung cancer and lung metastases.
