文题释义:
体外循环灌注系统:是由课题组多年前为解决离断肢体体外保存而设计的“体外模拟体内生理环境断肢寄养系统”改良而来的血液净化系统,前期研究已证实该系统具有模拟体内生理环境条件、清除断肢缺血坏死产物的作用,目前被用于下肢缺血性疾病及下肢挤压伤的临床及基础研究。
脉络宁:脉络宁注射液是在四妙勇安汤的基础上,以中医理论为指导,采用中西医结合的方法研究成的中药复方注射剂,由牛膝、金银花、玄参及石斛等中药组成。现代研究表明,脉络宁具有抗凝、溶栓、解痉、扩张血管、抗自由基以及改善微循环和内皮细胞保护作用及保护、修复血管等药理作用。
摘要
背景
:严重挤压伤及其引起的挤压综合征具有很高的致残率和致死率,严重威胁伤者生命。减少挤压解除后有害物质的回流入血是防治挤压综合征的关键。
目的:观察体外循环灌注系统下应用脉络宁注射液对猪下肢挤压伤-挤压综合征的防治作用。
方法:将巴马小型猪24只(购自北京通和生泰比较医学研究所)随机分为4组,每组6只,分别为正常对照组、模型组、常规灌注组及脉络宁灌注组,除正常对照组外其他3组用自制挤压装置行挤压伤造模,模型组造模完毕即刻恢复自身血供,常规灌注组与脉络宁灌注组分别给予常规血液灌注及脉络宁血液灌注1 h后恢复自身血供。
结果与结论:①血液生化及ELISA法检测显示,与模型组相比,常规灌注组和脉络宁灌注组灌注完毕后    48 h生存率升高,血清肌酐、尿素氮、钾离子、肌红蛋白、肌酸激酶、白细胞介素1β及白细胞介素水平明显降低(P < 0.05),脉络宁灌注组灌注完毕后6 h肌酸激酶、肌红蛋白水平低于常规灌注组(P < 0.05);②氧化应激因子检测显示,与模型组及常规灌注组相比,脉络宁灌注组骨骼肌丙二醛水平、胞浆内细胞色素C及凋亡诱导因子含量明显降低(P < 0.05),而骨骼肌超氧化物歧化酶活性、线粒体内细胞色素C及凋亡诱导因子含量显著升高(P < 0.05);③透射电镜结果显示,脉络宁灌注组骨骼肌超微结构较模型组及常规灌注组更接近正常组织,模型组与常规灌注组组织损伤情况相近;④结果表明,体外循环灌注系统下应用脉络宁对模型猪下肢挤压伤-挤压综合征具有一定的防治作用,可以为该病的治疗提供新的思路。

Abstract:

BACKGROUND: Severe crush injury and crush syndrome have high disability and mortality rates, which seriously threaten the lives of the injured. Reducing the return of harmful substances into blood after extrusion relief is the key to prevent and treat crush syndrome.
OBJECTIVE: To investigate the effect of combined application of extracorporeal circulation perfusion system and Mailuoning injection on crush injury and crush syndrome of lower extremity in pigs.
METHODS: Twenty-four Bama miniature pigs (provided by Beijing Tonghe Shengtai Institute for Comparative Medicine) were randomly divided into four groups (n=6/group): blank control, modeling, routine perfusion, and Mailuoning perfusion groups. The pigs in the latter three groups were used to establish the crush injury-crush syndrome model by self-made crush device. The modeling group restored blood supply after modeling immediately. The routine perfusion and Mailuoning perfusion groups respectively restored after receiving routine blood perfusion and Mailuoning perfusion treatment for 1 hour.
RESULTS AND CONCLUSION: The survival rate at 48 hours in the routine perfusion and Mailuoning perfusion groups were higher than that in the modeling group. Levels of creatinine, blood urine nitrogen, potassium ion concentration, myoglobin, creatine kinase, interleukin-1 beta and interleukin-6 in in the routine perfusion and Mailuoning perfusion groups were significantly decreased (P < 0.05). The levels of myoglobin and creatine kinase in the Mailuoning perfusion group at 6 hours were significantly lower than those in the conventional perfusion group (P < 0.05). Compared with the modeling and conventional perfusion groups, the malonaldehyde level in skeletal muscle, and contents of cytochrome C and apoptosis inducing factor in cytoplasm in the cytoplasm Mailuoning perfusion group were significantly decreased (P < 0.05), and the superoxide dismutase activity, and the contents of cytochrome C and apoptosis inducing factor in mitochondria were significantly increased (P < 0.05). Transmission electron microscope showed that the ultrastructure of skeletal muscle in the Mailuoning perfusion group was closer to the normal tissue than the modeling and conventional perfusion groups. The tissue injury condition was similar between modeling and conventional perfusion groups. These results indicate that the combined application of the extracorporeal circulation perfusion system and Mailuoning can prevent and treat the crush injury crush syndrome of the pig models and provide a new idea for the treatment of this disease.
