Erythropoietin prevents early and late neuronal demise through modulation of Akt1 and induction of caspase 1, 3, and 8

Erythropoietin (EPO) modulates primarily the proliferation of immature erythroid precursors, but little is known of the potential protective mechanisms of EPO in the central nervous system. We therefore examined the ability of EPO to modulate a series of death-related cellular pathways during anoxia and free radical induced neuronal degeneration. Neuronal injury was evaluated by trypan blue, DNA fragmentation, membrane phosphatidylserine exposure, protein kinase B phosphorylation, cysteine protease activity, mitochondrial membrane potential, and mitogen-activated protein (MAP) kinase phosphorylation. We demonstrate that constitutive neuronal EPO is insufficient to prevent cellular injury, but that signaling through the EPO receptor remains biologically responsive to exogenous EPO administration. Exogenous EPO is both necessary and sufficient to prevent acute genomic DNA destruction and subsequent phagocytosis through membrane PS exposure, because neuronal protection by EPO is completely abolished by co-treatment with an anti-EPO neutralizing antibody. Through pathways that involve the initial activation of protein kinase B, EPO maintains mitochondrial membrane potential. Subsequently, EPO inhibits caspase 8-, caspase 1-, and caspase 3-like activities linked to cytochrome c release through mechanisms that are independent from the MAP kinase systems of p38 and JNK. Elucidating some of the novel neuroprotective pathways employed by EPO may further the development of new therapeutic strategies for neurodegenerative disorders.

Imaging Findings of Hepatic Ewing’s Sarcoma on Computed Tomography and Gadobenate Dimeglumine-enhanced Magnetic Resonance Imaging: A Case Report and Literature Review

Ewing’s sarcoma (ES) is a tumor that often occurs in the long bones and rarely arises from visceral organs primarily. Here, we report a case of primary hepatic ES, discuss its computed tomography (CT) and gadobenate dimeglumine-enhanced magnetic resonance (MRI) features. This is the first Chinese and fifth primary hepatic ES case reported, based on a literature review. Imaging examinations showed that the tumor was solid, with necrosis and hemorrhage. Contrast-enhanced images showed that the tumor was hypervascular and especially had heterogeneous signal intensity on hepatobiliary phase MRI images. Intratumoral vessels and vascular invasion were also present.     

血清超敏C反应蛋白与尿碘水平联合预测先兆流产患者保胎结局的研究

目的观察血清超敏C反应蛋白(hs-CRP)与尿碘水平联合对先兆流产患者保胎结局的预测效能。方法前瞻性选取海南医学院第二附属医院2018年1月至2020年1月收治的112例先兆流产患者作为研究对象,根据保胎结局将患者分为保胎失败组(n=20)与保胎成功组(n=92)。检测两组入院时各主要指标[甲状腺功能相关指标、血清孕酮(P)、β-人绒毛膜促性腺激素(β-HCG)、hs-CRP、尿碘水平],采用Logistic回归分析各主要指标与先兆流产患者保胎结局的关系,并分析入院时血清hs-CRP、尿碘水平对先兆流产患者保胎结局的预测效能。结果保胎失败组P、β-HCG水平低于保胎成功组,hs-CRP水平高于保胎成功组,合并甲状腺功能异常、尿碘水平异常占比高于保胎成功组(P<0.05)。经Logistic回归分析结果显示,先兆流产患者甲状腺功能异常、hs-CRP表达上调、尿碘水平异常是保胎成功的危险因素(OR>1,P<0.05);先兆流产患者P、β-HCG表达上调是保胎成功的保护因素(OR<1,P<0.05);绘制受试者工作特征(ROC)曲线发现,先兆流产患者hs-CRP...

A Retrospective Analysis of Non-Sharps-Related Injuries in a Dental School

ObjectivesWorkplace non-sharps injuries are a common occurrence in a dental school setting. In dentistry, the importance of preventing non-sharps injuries is often overlooked due to emphasis on sharps-related injuries. The aim of this research was to analyse the incidences of non-sharps injuries over an 11-year period in a dental school to identify trends and the possible causative factors for these injuries.MethodsInjury reports lodged with the University of Queensland Workplace Health and Safety databases between 2009 and 2019 were categorised and analysed.ResultsOf 1156 incidents reported, 35.7% (n = 413) were non-sharps injuries, and the most common type of non-sharps injury was general incidents (48.4%, n = 200). The most common body site for injury was the hands (19.4%, n = 80), and the most common location where an injury occurred was in clinical patient care (53.8%, n = 222). The personnel type most at risk of a non-sharps injury fluctuated between students and staff throughout the study period.ConclusionsAll personnel, including students and staff, are at similar risk of experiencing a non-sharps injury within a dental school setting. The equipment and facilities of a dental clinic as well as the level of adherence to safe working procedures are contributing factors. Continuous quality improvement is essential for minimising these injuries.Key words: Acute injury, Dental school, Workplace health and safety
