2、组大鼠做双侧股骨骨折合并休克实验制造模型,各组分别于造模后0 h、2 h、4 h、6 h进行药物干预,空白对照组和模型对照组予生理盐水腹腔注射,参附注射液低、中、高剂量组分别以5 ml/kg、10 ml/kg、20 ml/kg剂量腹腔注射给药。实验过程中死亡大鼠立即进行解剖,切取肝脏标本。空白对照组大鼠直接活杀取相应组织及其标本。采用免疫组化法检测各组大鼠肝脏的NF-B和TNF-的蛋白表达水平。结果大鼠创伤失血性休克后NF-B和TNF-在肝组织中迅速表达,伤后6 h左右达到含量的高峰,伤后8 h仍持续在相当高的水平。与空白对照组比较,模型对照组及参附注射液低、中、高剂量组不同时间点(0.5 h
3、、2 h、4 h、6 h、8 h)肝组织NF-B、TNF-表达水平均明显升高,差异有统计学意义(P0.05);与模型对照组比较,参附注射液低、中、高剂量组不同时间点肝组织NF-B、TNF-表达水平均有不同程度下降,差异有统计学意义(P0.05);参附注射液低、中、高剂量组比较,不同时间点肝组织NF-B、TNF-的下降水平与剂量呈正相关关系,差异有统计学意义(P0.05)。结论 参附注射液通过抑制NF-B和TNF-的表达而减少创伤失血性休克的损伤,降低死亡率,进而发挥对肝脏的保护作用。关键词:创伤失血性休克;肝损伤;NF-B;TNF-;参附注射液中图分类号:R605.971文献标识码:A文章编号

7、创伤性休克属中医“脱证”范畴,称为“血脱”“脱血”,是导致多脏器功能不全甚至多脏器功能衰竭的主要因素或主要发病原因之一1。该病病机是各种原因如邪毒内陷、心阳衰微、亡津失液等导致人体阴阳不相顺接,进而出现阳气暴脱。因此,回阳救逆、益气固脱是本病的治疗原则。参附注射液中应用大补元气之人参配伍回阳救逆之附子,共奏回阳救逆、益气固脱之功效。在发生严重创伤或出血性休克的23 h 内,机体有效血容量明显减少,心输出量明显下降,导致血液灌流不足及微循环障碍,直接影响主要脏器如心、脑、肺、肝、肾等的功能2-3。研究表明4,在严重创伤性休克时,在肝组织中的核转录因子-B(NF-B)、肿瘤坏死因子-(TNF-)会
