Local application of corticosteroids combined with surgery for the treatment of chronic subdural hematoma.

Aim: Combination treatment consisting of surgery and pre-or post-operative corticosteroids for chronic subdural hematoma (CSH) tend to have better outcomes than surgery only. However, there are many complications after long-term use of corticosteroids. In this study, we evaluated the clinical outcomes of local application of corticosteroids combined with surgery for CSH.

Transplantation of neural stem cells overexpressing glial cell line-derived neurotrophic factor enhances Akt and Erk1/2 signaling and neurogenesis in rats after stroke.

Background: Our previous studies have indicated that the beneficial effects of grafting neural stem cells (NSCs) overexpressing glial cell line-derived neurotrophic factor (GDNF) in rats after stroke. However, the underlying mechanisms are highly debatable. In this study, we investigated whether neurogenesis, Akt, and extracellular signal-regulated kinase 1/2 (Erk1/2) signaling were involved in this process.
