Prognostic value of risk scoring systems for cirrhotic patients with variceal bleeding.

Background: Acute variceal bleeding is one of the deadliest complications of cirrhosis, with a high risk of in-hospital rebleeding and mortality. Some risk scoring systems to predict clinical outcomes in patients with upper gastrointestinal bleeding have been developed. However, for cirrhotic patients with variceal bleeding, data regarding the predictive value of these prognostic scores in predicting in-hospital outcomes are limited and controversial.

[Changes in the intestinal microenvironment during development of alcoholic fatty liver disease and related effects of probiotic therapy].

Objective: To investigate the initial changes in the gut microenvironment that accompany intestinal endotoxemia related to alcoholic fatty liver disease (ALD) in order to explore the potential initiating factors and to observe the effect of probiotic therapy on these factors.

Methods: Fifty Sprague-Dawley male rats were randomly divided into an ALD model group (alcoholic intragastric administration), an intervention group (ALD with probiotic intragastric administration), and a control group (physiological saline intragastric administration). Histological changes of the liver were evaluated using hematoxylin-eosin staining and light microscopy.
