Aim: To investigate whether hypoxia inducible factor (HIF)-1α modulates vasculogenic mimicry (VM) by upregulating VE-cadherin expression in esophageal squamous cell carcinoma (ESCC).
Methods: Esophageal squamous cancer cell lines Eca109 and TE13 were transfected with plasmids harboring small interfering RNAs targeting HIF-1α or VE-cadherin. The proliferation and invasion of esophageal carcinoma cells were detected by MTT and Transwell migration assays.
Objective: To investigate the effect of hypoxia inducible factor-1α (HIF-1α) on the proliferation, migration and vasculogenic mimicry(VM) in human esophageal squamous cell carcinoma cell line Eca-109 and gastric adenocarcinoma cell line SGC-7901 in vitro.
Methods: The recombinant plasmid pGCsi-shHIF-1α was transfected into Eca-109 and SGC-7901 cells by Lipofectamine(TM) 2000. The inhibitory effect of HIF-1α was measured at protein level by Western blot under normoxia and hypoxia.

Aim: To compare neoadjuvant chemoradiotherapy and surgery with surgery alone for resectable esophageal carcinoma.
Methods: We used MEDLINE and EMBASE databases to identify eligible studies and manual searches were done to ensure no studies were missed. Trial validity assessment was performed and a trial quality score was assigned.
