OBJECTIVE:
To analyze the rate of 235delC mutation in GJB2 gene in patients with idiopathic sudden hearing loss, and to explore its possible correlation with pathogenesis of idiopathic sudden hearing loss.
METHOD:
Two hundred and thirty-four patients with diagnosis of idiopathic sudden hearing loss in otolaryngology department were recruited as experimental group. Eighty people with normal hearing level were enrolled as control group. Their peripheral blood samples were obtained and genomic DNA was extracted. Using polymerase chain reaction, the coding region of GJB2 gene was amplified, and 235delC mutation is screened for in GJB2 gene by restriction endonuclease. At same time the clinical data of 234 patients was collected to analyze.
RESULT:
In 234 cases of idiopathic sudden hearing loss, 5 cases were found to have heterozygous 235delC mutation, none of them harbored homozygous 235delC mutation, the 235delC mutation rate was 2.1% (5/234). No 235delC mutation was found in control group. The rate of 235delC mutation in two group showed no statistically significant difference (P > 0.05).
CONCLUSION
This research shows that the rate of 235delC mutation in GJB2 is low in patients with idiopathic sudden hearing loss, and suggest that 235delC mutation possible has no correlation with idiopathic sudden hearing loss.

Intracranial atherosclerosis is one of the leading causes of ischemic stroke and occurs more commonly in patients of Asian, African or Hispanic origin than in Caucasians. Although the histopathology of intracranial atherosclerotic disease resembles extracranial atherosclerosis, there are some notable differences in the onset and severity of atherosclerosis. Current understanding of intracranial atherosclerotic disease has been advanced by the high-resolution magnetic resonance imaging (HRMRI), a novel emerging imaging technique that can directly visualize the vessel wall pathology. However, the pathological validation of HRMRI signal characteristics remains a key step to depict the plaque components and vulnerability in intracranial atherosclerotic lesions. The purpose of this review is to describe the histological features of intracranial atherosclerosis and to state current evidences regarding the validation of MR vessel wall imaging with histopathology.

Intracranial arterial calcification (IAC) is an easily identifiable entity on plain head computed tomography scans. Recent studies have found high prevalence rates for IAC worldwide, and this may be associated with ischemic stroke and cognitive decline. Aging, traditional cardiovascular risk factors, and chronic kidney disease have been found to be associated with IAC. The severity of IAC can be assessed using different visual grading scales or various quantitative methods (by measuring volume or intensity). An objective method for assessing IAC using consistent criteria is urgently required to facilitate comparisons between multiple studies involving diverse populations. There is accumulating evidence from clinical studies that IAC could be utilized as an indicator of intracranial atherosclerosis. However, the pathophysiology underlying the potential correlation between IAC and ischemic stroke-through direct arterial stenosis or plaque stability-remains to be determined. More well-designed clinical studies are needed to explore the predictive values of IAC in vascular events and the underlying pathophysiological mechanisms.
