摘要/Abstract

摘要： 采用EnVision^TM免疫组化方法,观察肝癌模型Wistar大鼠肝静脉阻断后肝癌及癌周组织、邻近肝叶、肺组织粘附分子1(ICAM-1)的表达变化,采用免疫测定法观察血浆中ICAM-1的变化,以探讨肝静脉阻断对肝癌生长、侵袭和转移的影响。发现:肝静脉阻断后肝癌组织ICAM-1的表达率为18.8%(9/48),较对照组(66.7%,8/12)明显下调(P<0.01);癌周组织ICAM-1的阳性表达率为33.3%(16/48),肝左中叶ICAM-1的阳性表达率为39.6%(19/48),与对照组比较均未见差异,而肺组织ICAM-1的表达率为70.8%(34/48),明显高于对照组(25.0%,3/12),P<0.05).肝静脉阻断后血浆ICAM-1含量明显高于肝静脉阻断前(P<0.01),对照组手术前后血浆ICAM-1含量无明显变化。结果提示肝癌肝静脉阻断可促进癌细胞向远隔器官(肺组织)转移。

Abstract: A hepatocellular carcinoma model of Wistar rat was constructed to study the expression of ICAM-1 in hepatocellular carcinoma and remote organs and to assess the growth, metastasis and invasion of cancer cell after the occlusion of hepatic vein. The change of expression of ICAM-1 in liver cancer, paracarcinoma tissue, nearby hepatic lobe and lung were measured by EnVision immunohistochemistry and the quantity of ICAM-1 in plasma by immunosurvey. The results showed that ICAM-1 in hepatocellular carcinoma tissue samples significantly downgraded after occulsion of hepatic vein compared with the control group(P<0.01). Positive samples of expression in paracarcinoma tissue(33.3%)and positive sample of expression in the left median lobe of the lever(39.6%)were fewer than the negative samples; while there were fewer positive samples than negative samples in hepatic left median lobe. However, we didn't find obviously discrepancy in contrast to the control group(P>0.05). The expression of ICAM-1 in the lung was higher than the control group(P<0.05). In plasma, the quantity of ICAM-1 extremely increased after the operation(P<0.01). Nevertheless, there wasn't a marked change found in the control group from pre-operation to post-operation. Therefore, we have the conclusion that the metastasis of malignant cell is different in different organs or tissues, and occlusion of hepatic vein accelerates cancer cell's transfer to remote part(lung)of body.
