Background: The surgical treatment of spontaneous posterior interosseous nerve(PIN)palsy with hourglass-like fascicular constriction(HLFC)remains controversial.
Objective: Recovery of central nervous system(CNS)after injury is limited in the mammalian adult,which is due a large part to the failure of CNS axons to grow.
Objectives Zinc ions have been extensively used as antibacterial implantable medical devices due to their broad-spectrum antibacterial activity and good osteogenesis effects.
Peripheral blood mesenchymal stem cells(PBMSCs)may be easily harvested from patient,therefore permitting autologous grafts for bone tissue engineering in future.However,the PBMSCs capabilities of surv
