Association of the Circulating Supar Levels with Inflammation, Fibrinolysis, and Outcome in Severe Burn Patients.

Background: Hyperfibrinolysis and pro/anti-inflammatory imbalance usually occur in the early stage of severe burns. Soluble urokinase-type plasminogen activator receptor (suPAR) is involved in fibrinolysis and inflammation. To date, the levels of circulating suPAR in non-survivors with severe burns remain unknown.

Effects of glutamine on intestinal mucus barrier after burn injury.

Severe burns may cause intense stress and persistent inflammation, resulting in intestinal mucosal barrier damage. In this study, we evaluated the effects of glutamine (Gln) on intestinal mucus barrier after burn injury. The results showed that glutamine could improve intestinal mucosal blood flow (IMBF), decrease diamine oxidase (DAO) activity, and reduce intestine damage, thereby alleviate intestinal mucous permeability.

IL-13 downregulates PPAR-gamma/heme oxygenase-1 via ER stress-stimulated calpain activation: aggravation of activated microglia death.

Interleukin 13 (IL-13) has been shown to induce the death of activated microglia. We observed that IL-13, but not IL-4 or IL-10, significantly enhanced endoplasmic reticulum (ER) stress induction, apoptosis and death in microglia activated by lipopolysaccharide (LPS). IL-13 enhanced ER stress-regulated calpain activation and calpain-II expression in LPS-activated microglia.

[Molecular diagnosis of a Chinese pedigree with osteogenesis imperfecta type I].

Objective: To perform molecular diagnosis for a Chinese pedigree with osteogenesis imperfecta type I.

Methods: Thirty pairs of primers were designed to amplify all the 52 exons, exon boundaries and promoter region of the COL1A1 gene from genomic DNA of peripheral blood cells of the family members. The PCR products were purified and directly sequenced.
