Stroke is one of the leading causes of disability and death in China, but its mechanism has not been thoroughly elucidated. As an important class of cells in maintaining neurological homeostasis, the intracellular calcium signaling of glial cells plays a dual role in mitigating and exacerbating neuronal damage in stroke and largely determines the progression and outcome of stroke. In this review of the literature, focusing on astrocytes, which account for the largest proportion of glial cells, we review the mechanism of glial calcium signaling after stroke and its effect on post-stroke neurological function, to provide reference for post-stroke neuroprotection and repair.

Due to the high theoretical capacity, Co3O4 has been regarded as one of the popular candidates for new anode materials in lithium-ion batteries recent years. However, the poor conductivity and cycling performance hinder its further development. In this work, Co3O4/C three-dimensional conductive networks with carbon nanotubes and graphene as conducive bridges and shells were prepared through carbornization and oxidation treatment using melamine and g-C3N4 as carbon sources and ZIF-8@ZIF-67 as self templates. The strategy of nanosizing particles and the evaporation and pore formation of zinc at high temperature result in the specific capacity of 1 139.7 mAh/g and 1 002.1 mAh/g after cycling for 200 and 800 cycles at current densities of 0.5 A/g and 2 A/g. Gradually increasing the current density of charging and discharging from 0.2 A/g to 10 A/g and then returning to 0.2 A/g, the material still reaches 94.9% of the initial capacity. This network structure exhibits superior cycling and rate performance compared to similar materials. [ABSTRACT FROM AUTHOR]
