Brain metastasis (BM) is a leading cause of death in patients with non-small cell lung cancer (NSCLC). EGFR mutations in primary NSCLC lesions have been associated with sensitivity to EGFR tyrosine kinase inhibitor (TKI). Therefore, it has become important to understand EGFR mutation status in BM lesions of NSCLC, and its clinical implications. BM samples(More)
BACKGROUND The aim of the present study was to analyze the expression of Zinc finger E-box Binding homeobox 2 (ZEB2) in glioma and to explore the molecular mechanisms of ZEB2 that regulate cell proliferation, migration, invasion, and apoptosis. METHODOLOGY/PRINCIPAL FINDINGS Expression of ZEB2 in 90 clinicopathologically characterized glioma patients was(More)
Epidermoid tumors located in the cerebellopontine angle (CPA) are challenging lesions because they tend to grow slowly in the subarachnoid cisterns around delicate neurovascular structures and often extend into surgical anatomic corners. The aim of this paper is to demonstrate the advantages and limitations of purely endoscopic removal of the CPA(More)
Objectives Quadrigeminal cistern arachnoid cysts (QCACs), which are usually asymptomatic and may be accidental findings during radiological evaluation, are rare, comprising 5-10% of all intracranial arachnoid cysts (ACs). We report a series of eight patients with QCACs treated with neuroendoscopic intervention and try to discuss the different endoscopic(More)
HDGF is overexpressed in gliomas as compared to normal brain. We therefore analyzed the molecular mechanisms of HDGF action in gliomas. HDGF was downregulated in normal brain tissue as compared to glioma specimens at both the mRNA and the protein levels. In glioma samples, increased HDGF expression was associated with disease progression. Knocking down HDGF(More)
The nephrotoxicity of cisplatin (cis-DDP) limits its general clinical applications. Lentinan (LNT), a dextran extracted from the mushroom Lentinula edodes, has been shown to have multiple pharmacological activities. The primary objective of the current study was to determine whether and how LNT alleviates cis-DDP- induced cytotoxicity in HK-2 cells and(More)
OBJECT An assessment regarding both surgical approaches and the extent of resection for Rathke cleft cysts (RCCs) based on their locations has not been reported. The aim of this study was to report the results of a large series of surgically treated patients with RCCs and to evaluate the feasibility of individualized surgical strategies for different RCCs.(More)
Rathke's cleft cysts (RCCs) are benign cysts typically located in the sellar or suprasellar region; ectopic isolated lesions are extremely rare. The authors describe the case of a 25-year-old man with a giant symptomatic RCC arising primarily at the cerebellopontine angle (CPA), only the second case reported thus far. The patient presented with a 2-year(More)
The ventriculoperitoneal (VP) shunt is an effective and the most common form of treatment for hydrocephalus. Rare complications such as migration of the distal catheter into the stomach [1], gallbladder [17], urinary bladder [2], liver [20], colon [5], and scrotum [7] have been described. The rarest complication appears to be intracardiac migration of the(More)
The study is to investigate the effects of paeoniflorin (PA) on renal function in cyclophosphamide-induced mice. Mice were injected with intraperitoneal cyclophosphamide (CYP, 200mg/kg) or saline respectively. Mice were treated with PA (15, 30mg/kg/day) or vehicle for the next 7 days. Then, mice were sacrificed to analyze the biochemical, histological(More)
