2颅内出血患者抗栓药逆转指南美国神经重症监护学会和美国重症医学会对医疗卫生专业人员的声明显示文摘背景抗栓药的使用,包括抗凝药、抗血小板药和溶栓药,在过去10年中日益增多并且预计将继续上升。虽然抗栓药相关性颅内出血可能是灾难性的,但快速逆转凝血功能障碍可能有助于限制血肿增大和改善转归。方法美国神经重症监护学会联合美国重症医学会组建了一个国际性多机构委员会,涉及的专业领域包括神经重症监护、神经内科、神经外科、卒中、血液学、血液病理学、急诊医学、药学、护理和指南制定,目的是进行文献评价并制定一份循证实践指南。该委员会进行了正式的文献检索,并对符合标准的研究进行了评价。结果利用GRADE方法学,委员会提出了在颅内出血情况下逆转维生素K拮抗药、直接Xa因子拮抗药、直接凝血酶抑制药、普通肝素、低分子肝素、类肝素、戊多糖、溶栓药和抗血小板药的推荐意见。结论该指南提供了及时和循证的抗栓药逆转策略以协助临床医生治疗抗栓药相关性颅内出血。Jennifer A.

4COREX工艺燃料比的影响因素显示文摘作为一种新型非高炉炼铁工艺,COREX工艺使用80%~85%非焦煤和15%~20%焦炭作为燃料,以满足对热量和还原剂的需求,并保证熔融气化炉内半焦床具有足够透气性。用于COREX工艺的非焦煤应满足一定的物化和高温性能,以稳定操作和提高产量。印度金达尔(JSW)钢铁厂拥有两座各年产80万t的COREX熔融还原炉,使用过几个煤种,发现不同煤种对操作会产生重要影响。统计分析表明,影响燃料比的主要因素包括煤的水分和挥发分、渣比和熔化速率。研究发现,生产率较高时,半焦床的稳定性和透气性就显得非常关键,因此反应后的半焦应具有较高的强度。P.

7Preparation and Characterization of Hydroxyapatite-Coated Selenium Nanoparticles and their Interaction with Osteosarcoma(SaOS-2) Cells显示文摘Nanotechnology has taken a firm step to revolutionize the field of orthopedic implants. Current research on bone implants focuses to develop implants with multifaceted functions viz., osteoinduction, chemoprevention, antimicrobial action etc., especially for cancerous bone resection. The objective of the present study was to synthesize a novel composite for bone implants, possessing the above properties. Selenium was selected owing to its chemopreventive and chemotherapeutic properties. Hydroxyapatite was selected owing to its bioactivity and similarity in composition to bone mineral properties. Selenium nanoparticles were prepared by chemical reduction method and coated with hydroxyapatite.Hydroxyapatite-coated selenium nanoparticle(HASnp) was characterized physico-chemically using fourier transform infrared spectroscopy, X-ray diffractometry, scanning electron microscope, and energy-dispersive X-ray spectroscopy.HASnp was analysed in vitro using SaOS-2 cell line. Enhanced cell proliferation and alkaline phosphatase activity were observed in HASnp-treated cells. The results indicate that HASnp is highly suitable for the use in orthopedic applications.Thiagarajan Hemalatha Gunasekaran Krithiga Baskar Santhosh Kumar Thotapalli P.

12搅拌摩擦加工对Al-TiB2复合材料在3.5 wt.%氯化钠溶液中腐蚀行为的影响(英文)显示文摘研究铸态和搅拌摩擦加工后的Al-TiB2 基复合材料在3.5 wt.%氯化钠溶液中的显微组织和腐蚀行为。采用X 射线衍射、扫描电镜和电子背散射衍射技术对材料的显微组织进行表征,并采用线性/循环动电位极化、电化学阻抗谱和ASTM-G67 测试评估材料的腐蚀行为。结果显示,复合材料铝基体中含有亚微米级的TiB2 颗粒,其周围围绕着块状和细小的Al3Ti 团簇,材料表现出较低且均匀的腐蚀速率。在动电位循环测验中,没有出现正循环曲线,证明其具有抵抗点蚀的能力,这归因于TiB2 粒子的非导电性本质和块状Al3Ti 相的含量可控。然而,无论是搅拌摩擦加工态还是铸态复合材料都容易发生晶间腐蚀,晶界处的Al3Ti 和TiB2 是腐蚀的起始位点;电化学阻抗研究表明,这是由于Al3Ti 和TiB2 对保护氧化膜具有不利影响,且随着浸泡时间的增加,其不利影响增加。Ritukesh SHARMA Amit Kumar SINGH Amit ARORA S.
