Abstract

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. After making model for 6, 12 and 24 hours, 6 rats were randomly selected from sepsis group and Xuebijing group, and then the rats were sacrificed, liver tissue samples were extracted for hematoxylin and eosin (HE) staining. Pathological changes of the liver were observed, and immunohistochemical analysis of liver tissue TCTP expression positive cells and the expression of TCTP in liver cells were detected by Western blotting method.

RESULTS:

HE staining of liver indicated that it was inflammatory injured in sepsis group, and inflammation decreased in Xuebijing group. Immunohistochemistry results showed that, compared with the control group, TCTP positive cells expression score at 6, 12 and 24 hours in sepsis group were significantly increased (7.33±0.82, 10.67±1.21, 7.67±1.21 vs. 2.50±1.05, all P<0.05). Compared with sepsis group, liver tissue TCTP positive cells expression score at 6, 12 and 24 hours in Xuebijing group (5.83±0.75, 7.50±1.05, 5.67±1.37) were significantly decreased (all P<0.05). Western blotting results showed that, compared with the control group, TCTP expression at 6, 12 and 24 hours in sepsis group were significantly increased (1.94±0.59, 3.20±0.72, 1.96±0.55 vs. 0.93±0.24, all P<0.05); compared with sepsis group, TCTP expression at 6, 12 and 24 hours in Xuebijing group (1.38±0.36, 2.03±0.49, 1.30±0.30) were significantly decreased (all P<0.05).

CONCLUSIONS:

Xuebijing can reduce inflammatory injury in liver of rats with Acinetobacter baumannii sepsis, and its mechanism may be associated with reduced hepatic cells expressed TCTP.
