Downregulation of microRNA-124-3p promotes subventricular zone neural stem cell activation by enhancing the function of BDNF downstream pathways after traumatic brain injury in adult rats.

Aims: In this study, the effect of intracerebral ventricle injection with a miR-124-3p agomir or antagomir on prognosis and on subventricular zone (SVZ) neural stem cells (NSCs) in adult rats with moderate traumatic brain injury (TBI) was investigated.

Methods: Model rats with moderate controlled cortical impact (CCI) were established and verified as described previously. The dynamic changes in miR-124-3p and the status of NSCs in the SVZ were analyzed.

Clinical and electrophysiologic features of childhood Guillain-Barré syndrome in Northeast China.

Background/purpose: Since little has been reported in previous studies, we aimed to find the clinical and electrophysiologic characteristics associated with childhood Guillain-Barré Syndrome (GBS) in Northeast China.

Methods: The clinical and electrophysiologic data were collected and reviewed retrospectively in 33 children and 105 adults with GBS during the period between 2006 and 2010 from the First Hospital of Jilin University.

Results: Most of the children with GBS were older than 8 years of age and symptoms were severe at GBS onset.

Evaluation of factors associated with pain experienced during mammary ductoscopy.

Background: The aim of this study was to evaluate patient characteristics and findings after mammary ductoscopy in an effort to reduce the pain experienced during the procedure.

Patients And Methods: We evaluated outpatients in whom mammary ductoscopy was performed under local or intraductal anesthesia without preference, and their clinical characteristics and findings were recorded. Average and maximum pain scores were determined after the examination for statistical analysis.

Clinical and histopathological features of familial amyloidotic polyneuropathy with transthyretin Val30Ala in a Chinese family.

Familial amyloidotic polyneuropathy (FAP) is characterized by extracellular deposition of amyloid fibrils caused by a point mutation in the transthyretin (TTR) gene. TTR amyloidosis is linked to a vast number of mutations with varying phenotype and tissue distribution. Several Chinese kindred with FAP type 1 have been reported in Beijing, Hong Kong, Taiwan, and elsewhere.
