To evaluate and describe CT and endoscopic imaging findings in patients with pathologically confirmed gastrointestinal tract lymphangiomas. Findings from imaging examinations in 6 patients with pathologically confirmed lymphangioma were retrospectively reviewed (computed tomographic images obtained in 6 patients and endoscopic images obtained in 4 patients(More)
Gastric varices are a major cause of gastrointestinal bleeding in patients with portal hypertension. Whatever therapeutic method is used, hemodynamic changes in the portal systemic shunt should be assessed. In this study, we used multi-detector row CT portography as a screening and assessment tool. A total of 85 patients with gastroscopy-confirmed(More)
Although transplanting mesenchymal stem cells (MSCs) can improve cardiac function and contribute to endothelial recovery in a damaged artery, natural MSCs may induce neointimal hyperplasia by directly or indirectly acting on vascular smooth muscle cells (VSMCs). Receptor activity-modifying protein 1 (RAMP1) is the component and the determinant of ligand(More)
Open source software facilitates software reuse as developers can learn from code in existing open source projects. However, license compliance is an important legal issue that should be taken into consideration during open source based software reuse. Ignorance or carelessness could result in huge financial losses. In this paper, we present LChecker, a(More)
The low survival rate of cardiac stem cells (CSCs) in the infarcted myocardium hampers cell therapy for ischemic cardiomyopathy. MicroRNA-21 (miR-21) and one of its target proteins, PTEN, contribute to the survival and proliferation of many cell types, but their prosurvival effects in c-kit+ CSC remain unclear. Thus, we hypothesized that miR-21 reduces(More)
OBJECTIVE To observe the effects of mesenchymal stem cells (MSC) modified by human receptor activity-modifying protein 1 (hRAMP1) on restenosis and cardiac function post-myocardial infarction (MI) and explore the therapeutic safety for gene modification of MSC. METHODS The double-injury rabbit model with MI reperfusion and sacculus damaged atherosclerotic(More)
OBJECTIVE Although earlier studies have shown that the transplantation of mesenchymal stem cells (MSCs) might improve cardiac functions after myocardial infraction, its role on vascular restenosis after percutaneous coronary intervention (PCI) remains controversial. The aim of this study was to investigate the effects of MSCs on the restenosis of injured(More)
Many existing methods on review spam detection considering text content merely utilize simple text features such as content similarity. We explore a novel idea of exploiting text generality for improving spam detection. Besides, apart from the task of review spam detection, although there have also been some works on identifying the review spam-mers (users)(More)
OBJECTIVE To explore the effects and mechanism of secretory calcitonin gene-related peptide (CGRP) and CGRP receptor modified mesenchymal stem cells on proliferation and phenotypic transformation of vascular smooth muscle cell. METHODS Firstly (Lenti-GFP-CGRP, referred to CGRP (+/+)) MSCs were transfected with high expression lentivirus vector of CGRP(More)
OBJECTIVE To investigate the effect of mesenchymal stem cells (MSCs) overexpressing human receptor activity modified protein 1 (hRAMP1) by adenovirus vector on infarction related inflammation and cardiac repair in a rabbit model of myocardial infarction (MI). METHODS Thirty rabbits underwent coronary artery ligation for 60 minutes followed by 24 hours(More)
