A new recombined porcine reproductive and respiratory syndrome virus virulent strain in China.

Porcine reproductive and respiratory syndrome (PRRS) is one of the most important swine diseases worldwide. In the present study, a new virulent strain of PRRS virus (PRRSV), GDsg, was isolated in Guangdong province, China, and caused high fever, high morbidity, and high mortality in sows and piglets. The genome of this new strain was 15,413 nucleotides (nt) long, and comparative analysis revealed that GDsg shared 82.

Performance of adaptive iterative dose reduction 3D integrated with automatic tube current modulation in radiation dose and image noise reduction compared with filtered-back projection for 80-kVp abdominal CT: Anthropomorphic phantom and patient study.

Objectives: Evaluate the performance of Adaptive Iterative Dose Reduction 3D (AIDR 3D) and compare with filtered-back projection (FBP) regarding radiation dosage and image quality for an 80-kVp abdominal CT.

Materials And Methods: An abdominal phantom underwent four CT acquisitions and reconstruction algorithms (FBP; AIDR 3D mild, standard and strong). Sixty-three patients underwent unenhanced liver CT with FBP and standard level AIDR 3D.

The clinicopathological features of sinonasal angiomatous polyps.

Background: Sinonasal angiomatous polyp (SAP) is a rare subtype of sinonasal polyp that might be misdiagnosed as a malignant lesion due to its clinical symptoms.

Methods: We retrospectively enrolled the patients who were diagnosed with SAP in our hospital during 2008-2015. We analyzed the clinical symptoms, radiological findings, and pathological features of all patients diagnosed with SAP.

Impact of spontaneous tumor rupture on prognosis of patients with T4 hepatocellular carcinoma.

Background And Objectives: Compare the outcomes of three groups of patients with T4 hepatocellular carcinoma (HCC): tumor rupture with shock (RS group), tumor rupture without shock (R group), and no tumor rupture (NR group).

Materials And Methods: We retrospectively reviewed 221 patients with T4 HCC from 2010 to 2012. The clinical background and prognosis were analyzed.

Liver metastasis from hepatoid adenocarcinoma of the stomach mimicking hepatocellular carcinoma: Dynamic computed tomography findings.

Aim: To evaluate the dynamic computed tomography (CT) findings of liver metastasis from hepatoid adenocarcinoma of the stomach (HAS) and compared them with hepatocellular carcinoma (HCC).

Methods: Between January 2000 and January 2015, 8 patients with pathologically proven HAS and liver metastases were enrolled. Basic tumor status was evaluated for the primary tumor location and metastatic sites.

The paracrine effects of adipose-derived stem cells on neovascularization and biocompatibility of a macroencapsulation device.

The foreign-body response to biomaterials compromises the performance of many biomedical devices by severe fibrosis and limited neovascularization. Mesenchymal stem cells are known to secrete cytokines for treating inflammatory conditions. In this study, we aim to investigate whether the paracrine products of adipose-derived mesenchymal stem cells (ADSCs) can affect the microenvironment of biomaterials and improve tissue responses to biomaterial implants.

Diameter change of common femoral arteries after percutaneous endovascular aortic repair with the use of the preclose technique.

Objective: One of the major concerns regarding the preclose technique is its influence on the diameter of the accessed common femoral artery (CFA). The aim of our study was to evaluate the CFA diameter change after percutaneous endovascular aortic repair (PEVAR) with the use of the preclose technique.

Methods: From February 2012 to September 2013, 192 patients who underwent PEVAR with the preclose technique were reviewed.

Kimura's disease: clinical and imaging parameters for the prediction of disease recurrence.

Kimura's disease is a rare chronic inflammatory disorder with a high rate of recurrence. The clinical and imaging features of Kimura's disease have been documented in the literature, but the relationship between these features and disease recurrence is still unclear. We conclude that disease duration of greater than 5 years, bilateral involvement, a lesion diameter of greater than 3 cm, a blood eosinophil count greater than 20%, and ill-defined lesions are predictive factors for the recurrence of Kimura's disease.
