The poor prognosis for patients with advanced malignancy relates partly to the inability to reverse cancer metastasis. In this study we have investigated an integrated immunotherapy method against pre-established metastases in three kinds of advanced cancer models including B16 melanoma, 4T1 breast tumor, and Hca hepatoma. The progression of metastases into(More)
OBJECTIVE To determine the role of extracellular signal-regulated kinase (ERK)1/2 during focal cerebral ischemia. METHODS Left middle cerebral artery occlusion (MCAO) was undergone after the introduction of a nylon suture to the left internal carotid artery in 70 male adult CD-1 mice. ERK 1/2 phosphorylation was detected using Western blot analysis, and(More)
BACKGROUND AND PURPOSE By 2010 there had been 14 published trials of surgery for intracerebral hemorrhage reported in systematic reviews or to the authors, but the role and timing of operative intervention remain controversial and the practice continues to be haphazard. This study attempted to obtain individual patient data from each of the 13 studies(More)
Hepatocellular carcinoma (HCC) is one of the most common malignancies worldwide with poor prognosis due to resistance to conventional chemotherapy and limited efficacy of radiotherapy. There is an urgent need to develop novel biomarkers for early diagnosis, as well as to identify new drug targets for therapeutic interventions. 54 paired HCC samples and 21(More)
PURPOSE Previous studies indicated that humoral or cellular immunity against murine vascular endothelial growth factor 2 (mFlk-1) was elicited to inhibit tumor growth. Here we describe a genetic fusion vaccine, pMBD2-mFlk-1, based on the targeting of a modified mFlk-1 to antigen-presenting cells by a murine beta-defensin 2 (MBD2) protein to induce both(More)
OBJECTIVE Metaplastic meningioma is a rare subtype of benign meningiomas, classified as WHO grade I with well prognosis. Here we presented our experiences on 15 cases of metaplastic meningioma, to investigate the clinicopathological features, therapies and prognosis of these cases. METHODS 15 patients underwent surgical treatment for intracranial(More)
OBJECTIVE Intracranial meningiomas, especially those located at anterior and middle skull base, are difficult to be completely resected due to their complicated anatomy structures and adjacent vessels. It's essential to locate the tumor and its vessels precisely during operation to reduce the risk of neurological deficits. The purpose of this study was to(More)
IL-37 is a potent inhibitor of innate immunity by shifting the cytokine equilibrium away from excessive inflammation. Psoriasis is thought to be initiated by abnormal interactions between the cutaneous keratinocytes and systemic immune cells, triggering keratinocyte hyperproliferation. In the current study, we assessed IL-37 in two well-known psoriasis(More)
The matrix (M) protein of vesicular stomatitis virus (VSV) plays a key role in inducing cell apoptosis during infection. To investigate whether M protein-mediated apoptosis could be used in cancer therapy, its cDNA was amplified and cloned into eukaryotic expression vector pcDNA3.1(+). The recombinant plasmid or the control empty plasmid pcDNA3.1(+) was(More)
Vesicular stomatitis virus (VSV) matrix protein (MP) is capable of inducing in vitro apoptosis of tumor cells in the absence of other viral components. Here, we report the potent antitumor and antimetastatic effects of recombinant plasmid pVAX-MP complexed with cationic liposome (DOTAP:Chol) against highly metastatic 4T1 mammary tumor. Mice with 10-day(More)
