External Forces

Abstract Background Neurotrauma is a head or spine injury caused by external forces. It is associated with oxidative stress, caused by the overproduction of peroxides and superoxides, and that can induce wound infection and trigger a serial of immunological reactions. The emerging catalysts have shown great potential for the treatment of brain injury and inhabiting neurogenic inflammation, but are limited to biosafety issues and delivery efficiency. Results Herein, we propose the noninvasive delivery route to brain trauma by employing highly active gold clusters with enzyme-like activity for achieving the early intervention. The ultrasmall gold clusters with unique size distribution show excellent catalytic activity with 10 times decomposition rate to H2O2. In vitro experiment shows the gold clusters can decrease the excessive O2•− and H2O2 compared with untreated cells. In vivo experiment shows gold clusters accelerate the wound healing of brain trauma and decrease the peroxide and superoxide of brain tissue. The western blot shows noninvasive treatment can decrease the inflammatory factors via inhibiting the activation of astrocytes and microglia. Conclusions Present work shows noninvasive treatment is a promising route for early intervention of brain trauma.

Secondary Damage

Abstract Background Neurotrauma is a worldwide public health problem which can be divided into primary and secondary damge. The primary damge is caused by external forces and triggers the overproduction of peroxides and superoxides, leading to long-lasting secondary damage including oxidative stress, wound infection and immunological reactions. The emerging catalysts have shown great potential in the treatment of brain injury and neurogenic inflammation, but are limited to biosafety issues and delivery efficiency. Results Herein, we proposed the noninvasive delivery route to brain trauma by employing highly active gold clusters with enzyme-like activity to achieve the early intervention. The decomposition rate to H2O2 of the ultrasmall gold clusters is 10 times that of glassy carbon (GC) electrodes, indicating excellent catalytic activity. The gold clusters can relieve the oxidative stress and decrease the excessive O2·− and H2O2 both in vitro and in vivo. Besides, gold clusters can accelerate the wound healing of brain trauma and alleviate inflammation via inhibiting the activation of astrocytes and microglia through noninvasive adminstration. decrease the peroxide and superoxide of brain tissue. Conclusions Present work shows noninvasive treatment is a promising route for early intervention of brain trauma.
