Increasing experimental and clinical data indicate that early brain injury (EBI) after subarachnoid hemorrhage (SAH) largely contributes to unfavorable outcomes, and it has been proved that EBI following SAH is closely associated with oxidative stress and brain edema. The present study aimed to examine the effect of hydrogen, a mild and selective cytotoxic(More)
BACKGROUND The goal of this report is to illustrate the use of intraoperative indocyanine green (ICG) angiography in the surgical management of intracranial aneurysms, including microsurgical clipping and revascularization. METHODS This study included a series of 45 patients who were surgically treated between June 2007 and May 2008 for intracranial(More)
Early brain injury (EBI), a significant contributor to poor outcome after subarachnoid hemorrhage (SAH), is intimately associated with neuronal apoptosis. Recently, the protective role of hydrogen (H2 ) in the brain has been widely studied, but the underlying mechanism remains elusive. Numerous studies have shown nuclear factor-κB (NF-κB) as a crucial(More)
OBJECTIVE To assess the preventive effect of sodium valproate on early posttraumatic seizures in traumatic brain injury (TBI) patients. METHODS The retrospective study was based on 159 patients with TBI treated at Department of Neurosurgery, Nanjing General Hospital of Nanjing Command enrolled between January 1, 2008 and December 31, 2009. The in-hospital(More)
OBJECTIVE To detect the hypermethylation status of RASSF1A promoter in serum DNA of non-small cell lung cancer (NSCLC) patient and evaluate its correlation with clinicopathological parameters. METHODS Serum DNA was extracted from the peripheral blood of 75 NSCLC patients and another 35 patients with benign pulmonary disease and 15 healthy donors. The(More)
AIM The anatomic characters and applicability of the extended pterional transtemporal transtentorial (EPTT) approach versus the subtemporal transtentorial (ST) approach for surgical treatment of petroclival tumors were evaluated. MATERIAL AND METHODS Ten sides from five adult Chinese injected cadavers were manipulated using both two approaches. Four deep(More)
OBJECTIVE To construct a dually targeting gene therapy system for pituitary adenomas and investigate its effect. METHODS Promoter hGHp containing human growth hormone gene was obtained from human genome and cloned into the plasmid pcDNA3.1/His A with the promoter cut to construct the recombinant plasmid pcDNA3.1/His A-hGHp. HSV-TK gene was obtained from(More)
