Prognosis of patients with gastric cancer and solitary lymph node metastasis.

Aim: To investigate the relationship of solitary lymph node metastasis (SLNM) and age with patient survival in gastric cancer (GC).

Methods: The medical records databases of China's Beijing Cancer Hospital at the Peking University School of Oncology and Shanghai Tenth People's Hospital affiliated to Tongji University were searched retrospectively to identify patients with histologically proven GC and SLNM who underwent surgical resection between October 2003 and December 2012. Patients with distant metastasis or gastric stump carcinoma following resection for benign disease were excluded from the analysis.

Computed tomography manifestations of common inferior vena cava dysplasia and its clinical significance.

This study aimed to review and analyse the computed tomography (CT) imaging results of frequently encountered developmental anomalies of the inferior vena cava (IVC). The underlying clinical significance was evaluated with reference to the relevant literature. CT images of patients who received abdominal or thoracic scanning between July 2009 and September 2011 were reviewed.

Emergency endovascular repair of complicated Stanford type B aortic dissections within 24 hours of symptom onset in 30 cases.

Objective: To investigate the results of emergency endovascular repair of complicated Stanford type B aortic dissections within 24 hours of symptom onset.

Methods: A retrospective analysis of the clinical data of 30 patients with complicated Stanford type B aortic dissections who underwent emergency endovascular repair between June 2007 and October 2008. Endovascular repairs were performed within 24 hours of symptom onset.

[Effect of overexpression of glycosylphosphatidylinositol-specific phospholipase D on biological character of hepatocellular carcinoma cell line HepG2].

Objective: To investigate the effect of overexpression of glycosylphosphatidyl-inositol-specific phospholipase D (GPI-PLD) on the biological character of hepatocellular carcinoma cell line HepG2.

Methods: The GPI-PLD gene eukaryon expression vector pcDNA3.1(+)/ GPI-PLD was transiently transfected into HepG2 cell by lipid-media transfection.
