Effect of emodin on small intestinal peristalsis of mice and relevant mechanism.
To investigate the effect of emodin on small intestinal peristalsis of mice and to explore its relevant mechanisms. ⋯ Emodin can enhance the function of small intestinal peristalsis of mice by mechanisms of promoting secretion of motilin, lowering the content of somatostatin and inhibiting Na+-K+-ATPase activity of small intestinal mucosa.

Tetrandrine inhibits activation of rat hepatic stellate cells in vitro via transforming growth factor-beta signaling.
To investigate the effect of various concentrations of tetrandrine on activation of quiescent rat hepatic stellate cells (HSCs) and transforming growth factor-beta (TGF-beta) signaling in vitro. ⋯ Tetrandrine has a direct inhibiting effect on the activation of rat HSCs in culture. It up-regulates the expression of Smad 7 which in turn blocks TGF-beta1 expression and signaling.

Case ReportsComputed tomography findings in fatal cases of enormous hepatic portal venous gas.
To assess the computed tomography (CT) findings in the patients with hepatic portal venous gas (HPVG) who presented with a short fatal clinical course in our hospital in order to demonstrate if there was any sign for prediction. ⋯ HPVG is a diagnostic clue in patients with acute abdominal conditions, and CT is the most specific diagnostic tool for its evaluation. The dry mesenteric veins are the suggestive fatal sign, especially for the deteriorating patients, with the direct effect on gastrointestinal perfusion.

Randomized Controlled Trial Clinical TrialEffect of water-soluble contrast in colorectal surgery: a prospective randomized trial.
Postoperative gastrointestinal-tract motility is normally delayed. Early feeding after colorectal surgery has been reported recently, but late feeding is common. Gastrografin not only enhances bowel peristalsis, but also decreases bowel-wall edema. Whether contrast medium allows early oral feeding and reduces the duration of hospitalization requires clarification. ⋯ Gastrografin not only allowed early oral feeding but also reduced the duration of hospitalization after elective colorectal surgery.

Dextrose in the banked blood products does not seem to affect the blood glucose levels in patients undergoing liver transplantation.
Hyperglycemia commonly seen in liver transplantation (LT) has often been attributed to the dextrose in the storage solution of blood transfusion products. The purpose of the study is to compare the changes of the blood glucose levels in transfused and non-transfused patients during LT. ⋯ We conclude that blood transfusion does not cause significant changes in the blood glucose levels in this study.
