Objective The aim was to investigate the protective effect and mechanism of hypothermia resuscitation on hepatic injury of hemorrhagic shock in rats.Methods 24 adult male Wistar rats were randomly assigned to three groups: control group(S), normalthermia group(N) and hypothermia group(H). Rats in the control group underwent the surgical procedure but were not bled. Rats in the normal thermia group and hypothermia group were received normal thermia (37-38℃) resuscitation or hypothermia (33-34℃) resuscitation respectively during resuscitation and hourly thereafter. Real-time PCR method detected the PPAR-γ, HSP70 and TNF-α mRNA expression in the rat hepatic tissues after resuscitation 240 minutes of hemorrhagic shock. The serum contents of TNF-α was assayed with ELISA. The serum contents of ALT and AST were assayed with biochemical methods.Results (1) The serum contents of TNF-α after 240 min of resuscitation was S group(8.53±1.90)ng/ml, N group (74.08±8.81)ng/ml, H group (32.13±5.82)ng/ml, the H group was lower than the N group (P<0.05); (2) The serum contents of ALT and AST after 240 min of resuscitation were S group (61±11)U/L, (47±9)U/L, N group (187±20)U/L, (139±15)U/L, H group (141±11)U/L, (97±11)U/L, the H group was lower than the N group (P<0.05); (3)compared with the control group, PPAR-γ mRNA expression in the N group and H group were 0.50±0.11 and 2.01±0.48 (P<0.05) after resuscitation 240 minutes of hemorrhagic shock; (4) compared with the control group, HSP70 mRNA expression in the N group and H group were 4.12±1.36 and 11.69±3.88 (P<0.05) after resuscitation 240 minutes of hemorrhagic shock; (5)compared with the control group, TNF-α mRNA expression in the NR group and HR group were 15.10±4.99 and 10.10±2.95 (P<0.05) after resuscitation 240 minutes of hemorrhagic shock (P<0.05).ConclusionHypothermia resuscitation after hemorrhagic shock can raise the PPAR-γ and HSP70 gene expression and inhibit TNF-α gene expression in the rat hepatic tissues. Hypothermia resuscitation also can inhibit the serum contents of TNF-α, ALT and AST. Hypothermia resuscitation can protect the hepatic function and was salutary effects for hemorrhagic shock.
