Central nervous system hemangiopericytoma (HPC) is a malignant vascularized mesenchymal tumor with a high rate of recurrence. Because of its rarity, few clinical characteristics and prognostic analysis information regarding recurrent HPC exist for doctors to pursue optimal outcomes. Forty-six recurrent HPC cases treated at our hospital between 2004 and 2012(More)
BACKGROUND To the best of the authors' knowledge, there are few case reports of penetrating brain injuries (PBI) caused by nail guns and these have usually involved incomplete penetration of the skull. Complete penetration of a nail into the intracranial cavity is extremely rare. CASE STUDY Here, two such cases are presented. In the first, the nail(More)
Oxidative stress is the principal factor in traumatic brain injury (TBI) that initiates events that result in protracted neuronal dysfunction and remodeling. Importantly, antioxidants can protect the brain against oxidative damage and modulate the capacity of the brain to cope with synaptic dysfunction and cognitive impairment. However, no studies have(More)
Hydrogen-rich water (HRW) has anti-oxidant activities, and it exerts neuroprotective effects during ischemia-reperfusion brain injury. Parvalbumin and hippocalcin are two calcium buffering proteins, which are involved in neuronal differentiation, maturation and apoptosis. The aim of this study was to investigate whether HRW could moderate parvalbumin and(More)
Inflammation and oxidative stress are the two major causes of apoptosis after traumatic brain injury (TBI). Most previous studies of the neuroprotective effects of hydrogen-rich water on TBI primarily focused on antioxidant effects. The present study investigated whether hydrogen-rich water (HRW) could attenuate brain damage and inflammation after traumatic(More)
OBJECTIVE Following traumatic brain injury (TBI), brain tissue that surrounding the regional primary lesion is known as traumatic penumbra; this region may undergo secondary injury and is considered to have the potential to recover. This review aimed to reveal the existence and significance of traumatic penumbra by analyzing all relevant studies concerning(More)
BACKGROUND Penetrating orbital injuries constitute a significant threat to ocular and cerebral structures. The incidence of central nervous system damage from orbital injury is related to the orbital anatomy and the characteristics of the penetrating object. Penetrating orbital injuries involving the brain stem are extremely rare. OBJECTIVES To present an(More)
Poly(ADP-ribose) polymerase (PARP) is activated by oxidative stress and plays an important role in traumatic brain injury (TBI). The objective of this study was to investigate whether PARP activation participated in the blood-brain barrier (BBB) disruption and edema formation in a mouse model of controlled cortical impact (CCI).(More)
Germinoma of basal ganglia in female is very rare. The authors present a case of germinoma located in the right temporal lobe and basal ganglia in female and raise a hypothesis for the sex disparity. A 13-year-old Chinese girl complained of weakness in the left extremities and intermittent headache for 2 years. Neuroimaging revealed an irregular lesion in(More)
Drinking is a risk factor for traumatic brain injury (TBI), and ethanol can aggravate the outcome by promoting brain edema. The mechanism involved is not fully understood. It has been confirmed that aquaporin-4 (AQP4) and vascular endothelial growth factor (VEGF) play pivotal roles in cytotoxic/vasogenic brain edema individually, and both of these proteins(More)
