Lymphatic metastasis is a continuous and complicated process. The detailed mechanisms of lymphatic metastasis are still not very clear, despite considerable research efforts in recent years. Previously, it was commonly accepted that there were no lymphatic vessels in the primary tumor. However, recent studies have demonstrated that lymphatic vessels are(More)
PURPOSE Advances in tumor biology and clinical trials indicate that p53 transfer is an alternative therapy for head and neck squamous cell carcinoma. The aim of this phase I clinical trial is to evaluate the feasibility, safety, and biologic activity of multiple intraepithelial injections of recombinant adenovirus (rAd)-p53 in patients with dysplastic oral(More)
Analysis of gene expression using RNA from the paraffin-embedded tissues is becoming an important way to study cancer pathogenesis. In this article, total RNA was extracted from tissue of 158 cases of paraffin-embedded tongue cancer, and expression of angiopoietin-like 4, tenascin-C and cathepsin-C were detected by real-time reverse transcriptase-polymerase(More)
OBJECTIVE To prepare and identify a polyclonal antibody (pAb) against (mouse) cysteinyl leukotriene receptor 1 (CysLT(1)) and to investigate the changes of CysLT(1) receptor expression in BV2 microglial cells after rotenone treatment. METHODS Rabbits were immunized with KLH-coupled CysLT(1) peptide to prepare the pAb. The titer of the pAb in rabbit plasma(More)
BACKGROUND In this study, a combination of recombinant adenoviral p53 (rAd-p53) gene therapy and intra-arterial delivery of chemotherapeutic agents for treatment of oral squamous cell carcinoma was evaluated. METHODS In total, 99 patients with stage III or IV oral carcinoma who had refused or were ineligible for surgery were enrolled in a randomized,(More)
OBJECTIVES The aim of this study was to define the biomarkers of lymphatic spread which facilitate the appropriate therapy for oral tongue squamous cell carcinoma (OTSCC) patients at early stage. Here, we investigated the expression levels of seven biomarkers in oral squamous cell carcinoma (OSCC) tissues as well as their associations with the(More)
With the development of modern steganography technologies, steganalysis has been a new research topic in the field of information security. Since JPEG images have been widely used in our daily life, the steganalysis for JPEG images becomes very important and significant. This paper propose a new steganalysis method based on sparse representation, intending(More)
To investigate the effects of phospholipase D (PLD) on low-concentration hydrogen peroxide (H(2)O(2))-induced growth and migration in alveolar epithelial A549 cells, the cells were exposed to H(2)O(2) (3-100 μM) for 12-48 hours, cell proliferation was determined by MTT assay and cell migration was tested by a modified epithelial wound healing assay. We(More)
This paper analyzed the worldwide situation of the human resources evaluation study, and constructed an indicator system for human resources evaluation based on some related literature , then adopted grey related TOPSIS method to construct evaluation model for human resources evaluation based on Entropy Weight. By counting the distance and grey relative(More)
Endovascular stent has an increasingly important application in the treatment of aneurysms. This study is to simulate Doppler ultrasound blood flow signals from a stented sidewall aneurysm based on a computational fluid dynamics model. For comparisons, a stented and non-stented sidewall aneurysm models are constructed respectively. Firstly the blood flow(More)
