心脏性猝死者心肌HO-1 和VEGF 的表达及意义

目的:探讨血红素加氧酶-1(hemeoxygenase-1,HO-1)、血管内皮生长因子(vascularendothelial growthfactor,VEGF)在心脏性猝死病人心室肌细胞中的表达及其意义.方法:运用免疫组织化学方法和Simple PCI图像分析系统观察33例心脏性猝死组和18例非心脏性猝死对照组尸检心肌组织中HO-1、VEGF蛋白的表达情况.结果:心脏性猝死组心肌组织HO-1(155.090±8.957)和VEGF蛋白表达(121.020±10.927)均显著高于非心脏性猝死对照组(116.200±6.355、84.207±4.402,均p<0.05).结论:HO-1和VEGF蛋白在心脏性猝死者心肌组织表达增强,可能与心脏性猝死有一定关系.

Abstract：

Objective: To investigate expression of the heine oxygenaso-1 (HO-I )and vascular endothelial growth factor (VEGF)in the left ventricle in patients with sudden cardiac death (SCD). Methods: Immunohistoehernistry and Simple PCI image analysis system were used to detect the expressions of riO-1 and VEGF in 33 eases of SCD and 18 eases of non SCD (control group). Results: The expressions of HO-1( 155.090± 8.957) and VEGF(121.020± 10.927) in the myoeardium of patients in SCD group were significantly higher than those in control group (116.200± 6.355, 84.207± 4.402 ,all p<0.05). Conclusions: The high expression of HO-1 and VEGF may be related with the sudden cardiac death to some extent.     

心脏性猝死者心肌HO-1和VEGF的表达及意义

目的：探讨血红素加氧酶-1（heme oxygenase-1,HO-1）、血管内皮生长因子（vascular endothelial growth factor,VEGF）在心脏性猝死病人心室肌细胞中的表达及其意义。方法：运用免疫组织化学方法和Simple PCI图像分析系统观察33例心脏性猝死组和18例非心脏性猝死对照组尸检心肌组织中HO-1、VEGF蛋白的表达情况。结果：心脏性猝死组心肌组织HO-1（155.090±8.957）和VEGF蛋白表达（121.020±10.927）均显著高于非心脏性猝死对照组（116.200±6.355、84.207±4.402,均p〈0.05）。结论：HO-1和VEGF蛋白在心脏性猝死者心肌组织表达增强,可能与心脏性猝死有一定关系。
