Ulinastatin protects pulmonary tissues from lipopolysaccharide-induced injury as an immunomodulator.
Organ protection is a routine therapy in patients with severe trauma, infection, and even multiple organ dysfunction syndrome. Appropriate inflammatory response benefits organ function with sepsis. Our aim was to verify the immunoregulatory effects of Ulinastatin (UTI) on lipopolysaccharide (LPS) administrated mice. ⋯ Our results demonstrated that UTI reduced LPS-induced pulmonary injury. The mechanism of its action might involve the immunoregulation and the mitigation of excessive inflammatory reaction.

Electroporation-mediated in vivo gene delivery of the Na+/K+-ATPase pump reduced lung injury in a mouse model of lung contusion.
Lung contusion (LC) is an independent risk factor for acute respiratory distress syndrome. The final common pathway in ARDS involves accumulation of fluid in the alveoli. In this study, we demonstrate the application of a potential gene therapy approach by delivering the Na+/K+-ATPase pump subunits in a murine model of LC. We hypothesized that restoring the activity of the pump will result in removal of excess alveolar fluid and additionally reduce inflammation. ⋯ Electroporation-mediated gene transfer of the subunits of the Na+/K+-ATPase pump enhanced recovery from acute inflammatory lung injury after LC.

Multicenter StudyBlunt splenic trauma: splenectomy increases early infectious complications: a prospective multicenter study.
The purpose of this study was to evaluate the effect of the method of splenic injury management on early infectious complications. ⋯ Splenectomy is an independent risk factor for early infectious complications. Splenic-preserving techniques should be considered more liberally.
