摘要目的 探讨CD40在肝硬化门静脉高压症患者脾脏中的表达及临床意义.方法 采用免疫组织化学S-P法测定50例肝硬化门静脉高压症患者和15例正常脾脏中CD40的表达情况.结果 CD40在正常脾脏与巨脾组织中的表达率分别为86.7%和36.0%,存在显著性差异(P＜0.05).CD40表达与肝功能Child分级及巨脾病理分级均呈负相关(P＜0.05).结论 CD40可能为临床评估肝硬化门静脉高压症患者脾脏免疫功能状态的重要指标.

abstractsObjective To investigate the expression and clinical significance of CD40 in the spleen of cirrhotic portal hypertension. Methods Expression of CD40 was determined with S-P immunohistochemistry in spleen specimens from 50 cases of cirrhotic portal hypertension and 15 healthy individuals. Results The CD40 positive rates in normal spleen and cirrhotic spleen were 86.7% and 36.0%, respectively. There was a significant difference between the 2 groups (P＜0.05). There was a negative correlation between the expression of CD40 and Child grades of liver function and cirrhotic splenic types(P＜0. 05). Conclusion CD40 might reflect the changes of splenic immune function,which might be one of more exact clinical examination indexes of splenic immune function.
