间充质干细胞在炎症性肠病治疗中的研究进展

现代医学研究表明炎症性肠病的发病机制与患者免疫失调具有密切关系。目前临床对于炎症性肠病治疗主要原则为消除活动性炎症以及改善免疫功能紊乱,比如氨基水杨酸制剂、免疫抑制剂以及糖皮质激素等均是临床治疗常用药物。间充质干细胞为具有自我复制以及多方向分化潜能的成体干细胞,对于组织修复以及免疫调节等均具有良好的治疗效果,目前在心肌梗死以及系统性红斑狼疮等疾病治疗中应用较为广泛。近些年很多专家将间充质干细胞应用于炎症性肠病的治疗中,取得了良好的效果。本文将这些新研究进展进行综述,以期为炎症性肠病的临床治疗提供借鉴。     

中药抗呼吸道合胞病毒实验研究进展

中药具有高效低毒的特点,分别从抗呼吸道合胞病毒(RSV)复方和单味中药提取物2个方面,总结中药对RSV的实验抑菌作用及其作用机制,期待为临床治疗提供理论依据,并为进一步挖掘和深入研究中药抗病毒成分提供新的思路。同时指出了单味中药提取物虽然可以较为清晰地说明治疗机制和作用靶点,但目前多数尚停留在物质分析、鉴定和少数动物细胞实验阶段。

Implementing remote triage in large health systems: A qualitative evidence synthesis

Remote triage (RT) allows interprofessional teams (e.g., nurses and physicians) to assess patients and make clinical decisions remotely. RT use has developed widespread interest due to the COVID‐19 pandemic, and has future potential to address the needs of a rapidly aging population, improve access to care, facilitate interprofessional team care, and ensure appropriate use of resources. However, despite rapid and increasing interest in implementation of RT, there is little research concerning practices for successful implementation. We conducted a systematic review and qualitative evidence synthesis of practices that impact the implementation of RT for adults seeking clinical care advice. We searched MEDLINE®, EMBASE, and CINAHL from inception through July 2018. We included 32 studies in this review. Our review identified four themes impacting the implementation of RT: characteristics of staff who use RT, influence of RT on staff, considerations in selecting RT tools, and environmental and contextual factors impacting RT. The findings of our systemic review underscore the need for a careful consideration of (a) organizational and stakeholder buy‐in before launch, (b) physical and psychological workplace environment, (c) staff training and ongoing support, and (d) optimal metrics to assess the effectiveness and efficiency of implementation. Our findings indicate that preimplementation planning, as well as evaluating RT by collecting data during and after implementation, is essential to ensuring successful implementation and continued adoption of RT in a health care system.     

Successful integration of the histology core laboratory in translational research

Abstract

In a diagnostic setting, the histology laboratory is a key resource for production of quality tissues so the pathologist can make an appropriate diagnosis. In a research setting, the histology laboratory is a valuable resource in providing an excellent quality product for publications and grants for the investigator. Optimal collaboration with research investigators requires that histotechnologists recognize the diverse challenges and opportunities in research. This paper emphasizes the importance of positive interaction with researchers, optimizing professional service for these clients and recognizing key services of histology laboratories in a research setting to maximize success.
