Cognitive impairments are observed in numerous patients following coronary bypass surgery, and piracetam are nootropic compounds that modulate cerebral functions by directly enhancing cognitive processes. The present meta-analysis was conducted to evaluate the protective effect of piracetam on the cognitive performance of patients undergoing coronary bypass(More)
PURPOSE To find a suitable rate of thoracic stent-graft oversizing by exploring its association with the occurrence of retrograde type A dissection (RTAD) after thoracic endovascular aortic repair (TEVAR) for type B aortic dissection. METHODS From January 2013 to June 2014, 203 patients (mean age 55 years; 167 men) with type B aortic dissection underwent(More)
Using different models of focal cerebral ischemia, the temporal and spatial rules of metabolism and energy changes in the post-ischemia brain tissue were measured by proton magnetic resonance spectroscopy (1HMRS) to provide valuable information for judging the prognosis of acute focal cerebral ischemia and carrying out effective therapy. Nine healthy(More)
OBJECTIVE To study whether recombinant adeno-associated virus (rAAV) mediated foreign gene, LacZ, could pass the blood brain barrier by intra-carotid artery delivery and express in vivo in ischemic brain of the focal embolic stroke rats to investigate a possibility of delivering foreign gene through carotid artery to treat acute ischemic stroke. METHODS(More)
OBJECTIVE The aim of this study was to explore the association between acquired multi-drug resistant organism (MDRO) and ventilator-associated pneumonia (VAP) in patients hospitalized at the intensive care unit(ICU). METHODS Real-time monitoring system for hospital infection was used to track VAP patients. The period of study was from January 1, 2013 to(More)
To investigate the expression of the HO-1 gene in PC12 cells in hypoxic environment and gain further insight to the role of HO-1 in cerebral ischemia, PC12 cells were exposed to hypoxia environment (95 % N2, 5 % CO2) for 0.5 h, 1 h, 4 h, 8 h, 12 h, 24 h respectively. The level of HO-1 mRNA was examined by reverse transcriptase polymerase chain reaction(More)
OBJECTIVE To test whether folic acid offers protection of the brain tissue against acute cerebral infarction in rats. METHODS Sprague-Dawley rats were divided into control (n=8), pre-treatment (n=12) and treatment (n=16) groups, all having routine feed for 7 days. The rats in the control and treatment groups were given normal saline daily, and those in(More)
OBJECTIVE This study sought to elucidate the underlying hemodynamic mechanisms involved in the longitudinal propagation of acute, type-B aortic dissections. METHODS Three-dimensional patient-specific aortic geometry was reconstructed from computed tomography images of 3 cases, followed by computational fluid dynamic analysis using finite-element analysis(More)
