[Differentially expressed proteins of severe acute pancreatitis intervened by Qingyi granule].

Objective: To observe the effects of Qingyi Granule (QYG) on the changes of total protein expressions in the pancreatic tissue of rats with severe acute pancreatitis (SAP) induced by sodium taurocholate (STC).

Methods: SAP was induced by retrograded injecting 5% STC from the gut-pancreatic duct in 36 Sprague-Dawley (SD)rats. Then they were randomly divided into the SAP group and the QYG treatment group (abbreviated as the QYG group), 18 in each group.

[Activation of nuclear factor-kappa B and its modulalorg effects on intercellular adhesion molecule-1 expression in mice with dextran sulphate sodium-induced rat colitis].

Objective: To investigate the changes in the activity of nuclear factor-kappaB (NF-kappa B) in mice with dextran sulphate sodium (DSS)-induced rat colitis and its modulalorg effect on intercellular adhesion molecule-1 (ICAM-1) expression.

Methods: Twenty normal male mice were randomized into DSS group and normal saline (NS) control group according to a matched-pair design. From days 1 to 7, the mice in DSS group were subjected to oral administration of 5%DSS solution, and from days 8 to 20, NS was given instead, for a total of 3 cycles.

A case-control study on children with Guillain-Barre syndrome in North China.

Objective: To explore the risk factors for Guillain-Barre syndrome.

Methods: Case-control study design was used in 51 cases of Guillain-Barre syndrome, and 51 matched controls. All of the 51 cases in this study had been examined by electrophysiology.
