Epidemiologic Characteristics of Work-related Eye Injuries and Risk Factors Associated with Severe Eye Injuries: A Registry-based Multicentre Study

ABSTRACT

Purpose

Work-related eye injuries have been reported with a variety of epidemiologic and clinical characteristics. We aimed to identify epidemiologic characteristics of work-related eye injuries and risk factors associated with severe injury in a large metropolitan city.     

Lucio phenomenon mimicking antiphospholipid syndrome: The occurrence of antiphospholipid antibodies in a leprosy patient

Lucio phenomenon is an atypical reaction of leprosy, characterized by vasculitic lesions that can mimic antiphospholipid syndrome (APS) clinically. Distinguishing the two can be difficult as antiphospholipid autoantibodies may be present in patients with leprosy. We report on a 32‐year‐old female patient presenting with a sudden onset of fever, hemorrhagic bullae, and skin necrosis on her lower legs. She was treated for APS due to the presence of antiphospholipid antibodies but had an inadequate response. A skin biopsy revealed thrombotic vasculopathy and necrotizing vasculitis associated with aggregation of foam cells in the perivascular area and subcutis, with acid‐fast bacilli in the histiocytes and blood vessel walls. Direct immunofluorescence showed IgM, C3, and fibrinogen deposition in the superficial and deep dermal blood vessels. The pathology confirmed the diagnosis of Lucio phenomenon, and appropriate therapy was given. It is essential to evaluate the patient comprehensively, including clinical, serological, and pathological aspects, to obtain the correct diagnosis.

电子线照射对小鼠胰岛素生长因子相关蛋白表达的影响

目的：探讨电子线对胰岛素生长因子-1家族蛋白表达的影响，为研究辐射对肝脏的早期损伤提供依据。方法：采用电子线照射小鼠，照射剂量为1、2、4 Gy，用Western blot法检测照射后12、48和72 h小鼠肝脏中胰岛素生长因子1受体（IGF-1R）、胰岛素生长因子结合蛋白1（IGFBP1）、胰岛素生长因子结合蛋白4（IGFBP4）和胰岛素生长因子1（IGF-1）蛋白表达水平的改变。结果：照射剂量为1 Gy时，与对照组相比，IGF-1蛋白在照射后48 h时表达增加，IGFBP1、IGFBP4和IGF1R蛋白的表达在照射后12、48和72 h均表达减少。照射剂量为2 Gy时，IGF-1和IGFBP4蛋白在照射后48 h时表达增加，其余时间点表达减少。IGFBP1蛋白在照射后12 h时表达增加，48和72 h时表达减少。IGF1R蛋白在照射后3个时间点均呈现为表达减少。照射剂量4 Gy时，肝脏中IGF-1、IGFBP1和IGFBP4蛋白均表达减少，IGF1R蛋白在照射后12 h时表达增加，48、72 h时均表达减少（均为P < 0.05）。结论：电子线照射后小鼠肝脏中胰岛素生长因子-1家族蛋白多以下调表达为主，与前期基因表达的结果相一致，有可能作为反映放射性工作人员早期肝脏损伤的生物标志物之一。     

The prognostic role of tumour‐infiltrating lymphocytes in oral squamous cell carcinoma: A meta‐analysis

It has been suggested that tumour‐infiltrating lymphocytes (TILs) are associated with the progression of oral squamous cell carcinoma (OSCC). However, the prognostic value of TILs is inconclusive due to the heterogeneity of immune cells within the tumour microenvironment. In this meta‐analysis, we aimed to assess the prognostic value of TILs in OSCC. The PubMed, Cochrane, Embase, Scopus and Web of Science databases were searched up to April 20, 2019, and 33 studies were ultimately included in this meta‐analysis. Our pooled meta‐analysis showed that high infiltration of CD8⁺ TILs, CD45RO⁺ TILs and CD57⁺ TILs favoured better overall survival (OS). However, high infiltration of CD68⁺ macrophages and CD163⁺ macrophages was associated with poor prognosis in OSCC. These findings suggest that CD8⁺ TILs, CD45RO⁺ TILs, CD57⁺ TILs, CD68⁺ macrophages and CD163⁺ macrophages might serve as novel prognostic factors and therapeutic targets in OSCC.
