Case report: successful resection of a leiomyoma causing pseudoachalasia at the esophagogastric junction by tunnel endoscopy.

Background: Pseudoachalasia is a rare disorder whose presentation strongly resembles idiopathic achalasia.

Case Presentation: Here, we present a case of a 42-year-old female patient with esophageal leiomyoma who was initially diagnosed with achalasia. On endoscopical investigation, however, it became apparent that she had pseudoachalasia as consequence of a leiomyoma at the esophagogastric junction (EGJ).

Induction of TGF-β and IL-10 production in dendritic cells using astilbin to inhibit dextran sulfate sodium-induced colitis.

Astilbin, a major bioactive compound from Rhizoma smilacis glabrae, has been reported to possess anti-inflammatory properties. Our study first evaluated astilbin on dextran sulfate sodium (DSS)-induced acute colitis in mice. By intraperitoneal injection of astilbin, the severity of colitis was attenuated, and the serum levels of IL-10 and TGF-β were increased.
