摘要: 目的 研究人脑挫伤后不同时间血红素加氧酶-1(heme oxygenase-1,HO-1)表达的变化,为法医学脑损伤时间的推断提供依据。 方法 选择24例因颅脑损伤死亡案例为损伤组,4例非颅脑损伤死亡的案例为对照组,应用免疫组织化学和图像分析技术,分别于脑损伤后存活时间3 h、6~9 h、12~24 h、36 h~3 d、5~8 d及17~20 d检测脑组织标本中HO-1随时间的变化规律。 结果 经统计学分析,HO-1阳性细胞表达在伤后3 h以内组开始升高,12~24 h组表达强度最高,36 h~3 d组仍见高表达,以后逐渐下降。各组组间及与对照组相比差异有统计学意义(P<0.05)。 结论 HO-1的表达可能成为实际检案中脑损伤时间推断的诊断指标。

Abstract: Objective To investigate the expression of heme oxygenase-1(HO-1) at different intervals and to provide evidence for estimation on injury intervals after brain contusion in human. Methods Twenty-four patients died of serious brain injury were assigned as injury group and 4 patients died of non-brain injury were served as control group. HO-1 expression was analyzed in brain tissue at different time intervals(3 h, 6-9 h, 12-24 h, 36 h-3 d, 5-8 d, 17-20 d) by immunohistochemistry and auto-image analysis system. Results The level of HO-1 expression started to increase in 3 h after brain contusion compared to the control group(P<0.05). The level of HO-1 expression highest level in 12-24 h group, and maintained high level in 36 h-3 d, then decreased gradually. Conclusion The expression of HO-1 might be a strong evidence for human brain contusion time estimation.
