摘要： 目的观察高血压病大鼠肢体挤压后的早期心肌损伤情况,并分析其在伤病关系分析中的意义。方法原发性高血压大鼠按打击程度随机分为4组,用自由落体装置打击大鼠右侧大腿,然后观察血压、心率变化,测量血清生化指标(肌酸激酶、肌酸激酶同功酶、乳酸脱氢酶、肌酐、尿素氮、α-羟丁酸脱氢酶、天门冬氨酸转移酶),并观察大鼠心、脑、肾的形态学改变。结果打击后大鼠血压、心率均有不同程度的上升,并且随着打击力度的增加而增加,但打击组间没有显著性差异。各组血清生化物表现为随打击力度的增加而上升,轻中重打击作为整体损伤组与对照组比较有显著性差异,天门冬氨酸转移酶、肌酸激酶、肌酸激酶同功酶在打击组间比较具有显著性差异。结论挤压性打击损伤造成了SHR早期心肌损伤,并且此指标可以运用于高血压病与损伤共存下的伤病关系分析。

Abstract: Objective To observe the changes of cardiac functional indicators in spontaneously hypertension rats (SHR) suffered by struck injuries of soft tissues, form which to discuss the significance in relationship between injury and disease. Methods SHRs were divided into four groups according to the degree, and whose thigh was struck with the homemade hit instrument. Then the blood pressure, heart rate as well as serum biochemical indicators (CK, CK-Mb, LDH, Cr, BUN, HBDH and AST) were examined. In addition, the morphological changes of heart, brain and kidney were also observed. Results The observe values of heart rate and blood pressure of SHRs seemed have relation to the degree of damage, but there were no statistically significance between different hit degree groups. In terms of serum biochemical indicators, all seven indicators of the hit group had significant difference with that of the control group, and the AST?CK?CK-MB levels were difference between the group of different strike degree. Conclusions Struck injuries of soft tissues can result in forepart damage of cardiac muscle. The biochemical indicators reflect the degree of injury, and they could be used as a type of objective enzymology indicators for analysis of the relationship between injury and disease in forensic practice.
