miRNAs play an important role in many human diseases, including cancer metastasis. However, the mechanisms by which miRNAs regulate intrahepatic cholangiocarcinoma metastasis remain poorly understood. In the present study, we assayed the expression level of miR-214 in intrahepatic cholangiocarcinoma tissues by real-time PCR, and defined the target gene and(More)
UNLABELLED Hepatitis C virus (HCV) infection usually induces chronic hepatic inflammation, which favors the initiation and progression of hepatocellular carcinoma (HCC). Moreover, microRNA-155 (miR-155) plays an important role in regulating both inflammation and tumorigenesis. However, little is known about whether and how miR-155 provides the link between(More)
The identification of independent prognostic indicators in distal bile duct carcinomas (DBDCs) has been limited by the small number of tumors and a lack of molecular prognostic markers. Markers assessed in combination may perform better than those considered individually. We conducted this study to identify prognostic predictors of patients with DBDC with(More)
BACKGROUND Treatments for cancer spinal metastasis were always palliative. This study was conducted to investigate the safety and effectiveness of IG-IMRT for these patients. METHODS 10 metastatic lesions were treated with conventionally-fractionated IG-IMRT. Daily kilovoltage cone-beam computed tomography (kV-CBCT) scan was applied to ensure accurate(More)
Intrahepatic cholangiocarcinoma (ICC) is a rare and highly aggressive malignancy. In this study, we identified the presence of gene deletion and missense mutation leading to inactivation or underexpression of liver kinase B1 (LKB1) tumor suppressor and excluded the involvement of LKB1 gene hypermethylation in ICC tissues. Immunohistochemical analysis showed(More)
Cholangiocarcinoma (CCA) is a common biliary malignancy. Despite continuing advances, novel indicators are urgently needed to identify patients with a poor prognosis. Several microRNAs (miRNAs) have been reported to be dysregulated in CCA tissues. The purpose of the current study was to explore the potential use of certain miRNAs as serum indicators. A(More)
The purposes of this study were to perform tests for the ArcCHECK QA system, and to evaluate the suitability of this system for IMRT and VMAT verification. The device was tested for short term reproducibility, dose linearity, dose rate dependence, dose per pulse dependence, field size dependence, out of field dependence and directional dependence. Eight(More)
Graphene has attracted a high level of research interest because of its outstanding electronic transport properties and optical properties. Based on the Kubo formalism and the Maxwell equations, it's demonstrated that the optical conductivity of graphene can be controlled through the applied voltage. And we find that the graphene-oxide-silicon (GOS) based(More)
An optical switch based on the multimode interference (MMI) coupler is demonstrated in this letter. The device is designed and fabricated in polymeric materials and the thermooptic (TO) effect of polymers, which has a negative TO coefficient, is employed to change the self-imaging effect of a side-heated MMI coupler and realize optical switching. The(More)
We present a hybrid graphene-silicon waveguide, which consists of a lateral slot waveguide with three layers of graphene flakes inside. Through a theoretical analysis, an effective index variation for about 0.05 is found in the waveguide by applying a voltage on the graphene. We designed a Mach-Zehnder modulator based on this waveguide and demonstrated it(More)
