Pure Mg and a Mg-6wt.% Zn alloy were investigated as potential candidates for biodegradable implants for the urinary system. The in vitro corrosion behavior was studied by potentiodynamic polarization and immersion tests in simulated body fluid (SBF) at 37°C. The in vivo degradation and histocompatibility were examined through implantation into the bladders(More)
Posterior reversible encephalopathy syndrome (PRES) is a clinical-radiological syndrome characterized by reversible vasogenic edema typically at a posterior location of the cerebrum. PRES with prominent brainstem or basal ganglia involvement is defined as central-variant, which is rare. We herein report an atypical case of a 35-year-old man with a 2-year(More)
OBJECTIVE To provide a comprehensive and latest overview of susceptibility-weighted imaging (SWI) in the application of thrombolysis in acute ischemic stroke, and to update the decision-making effect and clinical value of SWI on identifying stroke patients suitable for thrombolytic therapy and possible benefits and risks followed. DATA SOURCES Literatures(More)
AIM To explore the dynamic changes in the pressure of the lateral ventricle during acute brainstem hemorrhage and the changes of neural discharge of vagus nerve under the load of intracranial hypertension, so as to analyze their effects on the congestive degree of intestinal mucous membrane and the morphologic changes of intestinal mucous membrane.

We measured the prevalence of active epilepsy and investigated the treatment gap and treatment gap risk profile in eastern China. This was a cross-sectional population-based survey conducted in Zhejiang, China, from October 2013 to March 2014. A total 54,976 people were selected using multi-stage cluster sampling. A two-stage questionnaire-based process was(More)
The Vancouver Classification System (VCS) for assessing periprosthetic femoral fractures has become universally accepted. The Unified Classification System (UCS) has expanded upon and updated the VCS and applied treatment principles to all periprosthetic fractures. However, periprosthetic femoral fractures accompanied by stem fracture after hip arthroplasty(More)
BACKGROUND AND PURPOSE It has been reported that taking antiepileptic drugs (AEDs) may increase the risk of atherosclerosis. We performed a meta-analysis to evaluate the carotid artery intima-media thickness (CA-IMT) as a surrogate factor for atherosclerosis in epileptic patients. METHODS We searched NCBI (PubMed), ISI Web of Knowledge, EMBASE, and the(More)
BACKGROUND In the present analysis, we investigated the association of serum uric acid with aortic stiffness and pressure as measured by carotid-femoral pulse wave velocity (cf-PWV) and central systolic blood pressure (SBP), respectively. METHODS Our study was conducted in the framework of cardiovascular health examinations for the employees of a factory(More)
In recent years, magnetic resonance imaging (MRI) has become more widely used in neonatal hypoxic-ischemic encephalopathy (HIE), involving, for example, evaluation of cerebral edema, white matter fiber bundle tracking, cerebral perfusion status, and assessment of brain metabolites. MRI has many imaging modalities. However, its application for assessing(More)
OBJECTIVE To investigate the relation between sinus-straddling hematoma (SSH) and venous sinus injury and explore the approaches for surgical management. METHODS Thirty-six cases of stride sinus hematoma were reviewed to observe the incidence rate of sinus injury complicated with (SSH) and explore its surgical management. RESULTS The incidence rate of(More)
