创伤性休克大鼠肝组织HSP70 mRNA表达变化及甘氨酸的干预影响

目的观察创伤性休克大鼠肝组织HSP70 mRNA表达变化及甘氨酸的干预影响。方法检测甘氨酸治疗组、休克组和对照组肝组织HSP70 mRNA表达；观察肝组织病理改变并测定血清ALT和AST水平。结果休克组和治疗组肝组织HSP70 mRNA表达分别于复苏后6、12h达高峰。血清ALT、AST随时间延长逐渐增高；光镜下病理改变也随时间延长而损害加重。与休克组比较，治疗组肝组织HSP70 mRNA表达明显增强、血清ALT和AST明显降低且肝组织光镜下病理损害明显改善（P均〈0．05）。结论甘氨酸可增强肝组织HSP70表达，减轻创伤性休克后继发的肝脏损害。

Dynamic changes of HSP70 mRNA expression in liver tissue of rats with traumatic shock and the treatment effects of glycine

Objective To investigate the dynamic changes of HSP70 mRNA expression in the liver tissue of rats with traumatic shock and the treatment effects of glycine.Methods The expression of HSP70 mRNA in the liver tissue of treatment group,shock group and control group was detected by ELISA.Pathological changes were observed,and serum ALT and AST were measured.Results The expression of HSP70 mRNA in the liver tissue of rats in the shock group and the treatment group reached peak at the 6th and 12th hour after resuscitation respectively.Serum ALT and AST increased and pathological damage aggravated with time prolonging.Compared with control group,the expression of HSPT0 mRNA in treatment group increased significantly,serum ALT and AST decreased significantly and pathologi- cal damage was significantly relieved(all P<0.05).Conclusion Glycine can increase the expression of HSPT0 mRNA and relieve the secondary damage of liver after traumatic shock.
