摘要
目的探讨凋亡抑制蛋白Livin和促凋亡蛋白Smac在胰腺癌组织中的表达及其临床意义。方法利用免疫组化sP法检测46例胰腺癌、15例胰岛素瘤和14例正常胰腺组织中Livin和Smae的表达，分析其与胰腺癌临床病理特征的关系。结果胰腺癌、胰岛素瘤和正常胰腺组织Livin蛋白表达率分别为73．9％（34／46）、73．3％（11／15）和14．3％（2／14）。胰腺癌、胰岛素瘤均高表达，两者间差异无统计学意义，但均显著高于正常胰腺组织（P值均〈0．05）。Livin蛋白的表达与胰腺癌淋巴结转移、组织病理分级及临床分期有关（P〈0．05或〈0．01）。胰腺癌、胰岛素瘤和正常胰腺组织Smac蛋白表达率分别为39．1％（18／46）、100％（15／15）和92．9％（13／14）。正常胰腺和胰岛素瘤组织均高表达，两者间差异无统计学意义，但均显著高于胰腺癌组织（P值均〈0．05）。Smac蛋白的表达与胰腺癌淋巴结转移、组织病理分级、临床分期及患者年龄有关（P〈0．05或〈0．01）。结论Livin可能在胰腺癌的发生、发展中起重要促进作用，而Smac在防止胰腺癌的发生、发展中起一定的作用。
Objective To investigate the expression and clinical significance of apoptosis inhibitory protein, Livin and Smac,in pancreatic carcinoma. Methods The expressions of Livin and Smac protein in 46 cases of pancreatic carcinoma tissues and 15 cases of insulinoma tissues and 14 cases of normal pancreatic tissues were examined by using immunohistochemical SP staining, and its relationship with clinicopathological parameters was analyzed. Results The positive expression rates of Llivin protein were 73.9% （ 34/46 ）, 73.3% （ 11/15 ） and 14.3% （2/14） in pancreatic carcinoma, insulinoma and normal pancreatic tissue. Livin was highly expressed in pancreatic carcinoma and insulinoma, but there was no significant difference between the two groups, however, both were significantly higher than that in normal pancreatic tissues group （ P 〈 0.05 ）. The expression of Livin was significantly correlated with lymph node metastasis, histopathological grading and clinical staging （ P 〈 0.05 or P 〈 0.01 ）. The positive expression rates of Smae protein were 39.1% （ 18/46 ）, 100% （ 15/15 ） and 92.9% （ 13/14 ） in pancreatic carcinoma, insulinoma and normal pancreatic tissue. Smac was highly expressed in normal pancreatic tissues and insulinoma, but there was no significant difference between the two groups, however, both were significantly higher than that in pancreatic cancer group （P 〈 O. 05 ）. The expression rate of Smac protein was significantly correlated with lymph node metastasis, histopathological grading, clinical staging and patients＇ age （P 〈0.05 or P 〈0.01 ）. Conclusions Livin protein may play an important role in genesis and development of pancreatic carcinoma, but Smac protein may play a role in preventing the development of pancreatic carcinoma.
