Inhibition of ALDH2 expression aggravates renal injury in a rat sepsis syndrome model.

Mitochondrial aldehyde dehydrogenase 2 (ALDH2) is closely associated with organ injury. The aim of the present study was to investigate the change of ALDH2 expression in a rat model of sepsis-induced acute renal injury, and to observe the effect of ALDH2 inhibition on the kidney. A model of sepsis syndrome was established in Sprague-Dawley (SD) rats by cecal ligation and puncture (CLP).

[Changing laws of serum high mobility group box 1 protein in septic rats and the intervention effect of xuebijing].

Objective: To investigate the changing laws of serum high mobility group box 1 protein (HMGB1) in septic rats and intervention effect of Xuebijing on it.

Methods: Lipopolysaccharide (LPS) (5 mg/kg BW) was intravenously injected into the tail vein of healthy male Wistar rats to prepare the sepsis rat model. In Experiment 1: 50 Wistar rats were randomly divided into three groups, i.

Xuebijing Protects Rats from Sepsis Challenged with Acinetobacter baumannii by Promoting Annexin A1 Expression and Inhibiting Proinflammatory Cytokines Secretion.

Xuebijing (XBJ) injection is a herbal medicine that has been widely used in the treatment of sepsis in China; however, its role in the development and progression of Acinetobacter baumannii sepsis and the underlying mechanisms remain uninvestigated. In the present study, fifty-four male Wistar rats were randomly assigned to normal-control group, sepsis-control group, and sepsis + XBJ group, each containing three subgroups of different treatment time periods (6, 12, and 24 hrs following injection, resp.).

[The effect of Xuebijing on liver translationally controlled tumor protein expression in Acinetobacter baumannii sepsis rats].

Objective: To study the effect of Xuebijing on liver expressing translationally controlled tumor protein (TCTP) in Acinetobacter baumannii sepsis rats.

Methods: Among 42 healthy adult male Wistar rats of clean grade, 6 rats were randomly selected as the control group, others were randomly divided into two groups by the method of random digits table: sepsis group(n=18), Xuebijing group(n=18). Sepsis model was established through intraperitoneal injecting Acinetobacter baumannii suspension, and the Xuebijing injection was administrated through caudal vein 30 minutes later in Xuebijing group.

[The changes of inducible nitric oxide synthase activity and apoptosis-related gene expression in endotoxemia-induced rat diaphragm].

Objective: To study the changes of inducible nitric oxide synthase (iNOS) activity and apoptosis-related genes Bcl-2, Bax and caspase-3 mRNA expressions in endotoxemia-induced rat diaphragm injury and analyze the related apoptosis mechanism.

Methods: Thirty-two male SD rats were randomly divided into 4 groups (n = 8): control group (saline 0.5 ml ip), endotoxin 24 h, 48 h and 96 h group (endotoxin 12 mg/kg ip, animals were killed either 24, 48 or 96 h after injections).
