血小板输注无效(platelet transfusion refractori⁃ness,PTR)是临床较难解决的问题,免疫性PTR由人类白细胞抗原(human leukocyte antigen,HLA)抗体、血小板同种抗原(human platelet allo antigen,HPA)抗体、ABO血型抗体、糖蛋白自身抗体等因素引起,其中HLA抗体为主要因素[1~3]。解决免疫性PTR的方法为供受者之间的血小板配型,包括血清学配型和基因配型[4,5]。基因配型是在前期建设一定库容量的血小板供者库后,对于每次的PTR患者输血,只需进行供受者之间虚拟电子配型.

LiNi_(0.8)Co_(0.15)Al_(0.05)O_(2)(NCA) is a promising cathode for sulfide-based solid-state lithium batteries(ASSLBs)profiting from its high specific capacity and voltage plateau, which yielding high energy density. However, the inferior interfacial stability between the bare NCA and sulfides limits its electrochemical performance. Hereien, the dual-electrolyte layer is proposed to mitigate this effect and enhance the battery performances of NCA-based ASSLIBs. The Li_(3)InCl_6 wih high conductivity and excellent electrochemcial stability act both as an ion additives to promote Li-ion diffusion across the interface in the cathode and as a buffer layer between the cathode layer and the solid electrolyte layer to avoid side reactions and improve the interface stability. The corresponding battery exhibits high discharge capacities and superior cyclabilities at both room and elevated temperatures. It exhibits discharge performance of 237.04 and216.07 m Ah/g at 0.1 and 0.5 C, respectively, when cycled at 60 ℃, and sustains 95.9% of the capacity after100 cycles at 0.5 C. The work demonstrates a simple strategy to ensure the superior performances of NCA in sulfide-based ASSLBs.

改革开放以来,我国高校逐步形成了以思想政治理论课考试成绩为主的德育评价模式。这种科学主义取向的德育评价范式,注重评价的客观性和精确性,却忽视了德育评价的内隐性、复杂性和人本性,其局限性在实践中日益暴露。高校德育评价范式的转变是思维模式与实践方法的整体性变革,主要包括价值取向、评价主体、评价标准、评价方法以及评价结果等范畴。高校德育评价范式的转变是新范式对旧范式否定、批判和扬弃的过程,所以应从重构德育评价哲学、创新德育评价机制、优化德育评价方法和提升德育评价素养等方面来推进我国高校德育评价范式的顺利转变。
