OBJECT The authors retrospectively analyzed data on brainstem gangliogliomas treated in their department and reviewed the pertinent literature to foster understanding of the preoperative characteristics, management, and clinical outcomes of this disease. METHODS In 2006, the authors established a database of treated lesions of the posterior fossa. The(More)
Decreased skeletal muscle mass and proportion of fast-twitch glycolytic fibers are well-documented correlates of aging; however, data on concomitant changes on capillary-to-fiber ratio (C:F) are inconsistent. We simultaneously examined fiber-type composition and arteriolar and venular portions of capillaries in the distal hind-limb muscles of 12-, 24-, and(More)
OBJECT The authors retrospectively analyzed the clinical characteristics, existing problems, and treatment experiences in recently diagnosed cerebral paragonimiasis (CP) cases and sought to raise awareness of CP and to supply reference data for early diagnosis and treatment. METHODS Twenty-seven patients (22 male and 5 female; median age 20.3 years, range(More)
OBJECTIVE To investigate the advantages, disadvantages and indications of hemilaminectomy for microsurgical resection of intraspinal tumors. METHODS We retrospectively reviewed and analyzed the clinical data of 542 cases of intraspinal tumors microsurgically resected by hemilaminectomy during the period from January 2005 to December 2008. RESULTS The(More)
OBJECTIVE To observe the expression levels of BDNF and bFGF, the variation of superoxide dismutase (SOD) and malondialdehyde (MDA) in serum and injury neuron of rat, and to evaluate the effect of Tetramethylpyrazine (TMP) on neuro-protection finally. METHODS 120 SD rats were randomly assigned into three groups: pseudo-operation group, severe brain injury(More)
BACKGROUND Cavernomas are rare in the brainstem and account for 18-35% of central nervous cavernomas and can cause recurrent hemorrhages, devastating neurological deficits and mortality. OBJECTIVES To summarize the experience of microsurgical treatment of brainstem cavernomas and to investigate curative effect of microsurgical treatment of brainstem(More)
PURPOSE To summarize the clinical and radiologic features of pediatric basal ganglia region tumors (PBGRT) in correlation with their histopathologic findings to reduce inappropriate surgery and identify tumors that can benefit from maximal safe resection. METHODS The records of 35 children with PBGRT treated in our hospital from December 2011 to December(More)
BACKGROUND & OBJECTIVE Pituitary adenoma, a kind of familiar benign intracranial tumor, is mainly treated with surgical operation, medication, and radiation. However, the outcome, especially for giant pituitary adenoma, is not very satisfactory. This study was to explore the efficacy of total tumor removal or subtotal tumor removal combined gamma knife(More)
OBJECTIVE To evaluate the relationships of CXCR4 (chemokine stromal cell-drived factor-1 receptor) and VEGF (vaseular endothelial growth factor) expression to tumor angiogenesis in hemangioblastomas of the central nervous system. METHODS The protein expressions of CXCR4 and VEGF were detected by SP immunohistochemical staining in 40 hemangioblastomas. The(More)
BACKGROUND AND PURPOSE The early diagnosis of cerebral paragonimiasis (CP) is essential for a good prognosis. We seek to provide references for early diagnosis by analyzing the imaging characteristics of cerebral paragonimiasis. MATERIALS AND METHODS Images of 27 patients with CP (22 males and 5 females; median age 20.3 years; range: 4 to 47 years) were(More)
