Gene expression profiling facilitates the understanding of biological characteristics of gliomas. Previous studies mainly used regression/variance analysis without considering various background biological and environmental factors. The aim of this study was to investigate gene expression differences between grade III and IV gliomas through partial least(More)
OBJECTIVE To study the diagnosis and treatment of spinal cord hemangioblastoma. METHOD The clinical data of 42 patients with spinal cord hemangioblastoma who were operated on between 1997 and 2005 were analyzed. RESULT Spinal cord hemangioblastoma mostly showed space occupying lesions with clear boundary and Dd-DTPA homogenous enhancement by MRI. All(More)
OBJECTIVE To discuss the reasonable choice of the surgical approach to petroclvial tumors. METHODS The clinical data of consecutive 53 patients with the petroclival tumors, treated from June 2002 to June 2004, were reviewed to compare the different surgical approaches to pertroclival region. RESULT Subtemporal transtentorial approach were used in 11(More)
