[摘要] 目的 了解胆囊癌组织中骨桥蛋白和MMP-9的表达及其意义。方法 选择正常的胆囊组织10例、胆囊腺瘤组织10例和胆囊癌组织40例，运用免疫组织化学方法，检测OPN和MMP-9的表达水平，对OPN和MMP-9表达的相关性进行分析研究。结果 胆囊癌组织中OPN和MMP-9的表达水平明显高于胆囊组织和胆囊腺瘤组织(P<0.05)，其中在有转移的胆囊癌组织中OPN的表达水平明显高于没有转移的胆囊癌组织(P<0.05)。胆囊癌组织中OPN和MMP-9的表达具有一致性(P<0.05)。结论 OPN与MMP-9的表达情况与胆囊癌浸润、转移发生有密切的关系，本实验结果证实MMP-9和OPN均阳性表达时对胆囊癌转移及预后有重要的预测价值。

[Abstract] Objective To explore expression of osteopontin and MMP-9 in gallbladder cancer and its clinical significance. Methods The expression of osteopontin and MMP-9 was detected by immunohistochemical method in 40 cases of gallbladder cancer，10 cases of normal gallbladder and 10 cases of gallbladder adenoma. The relationship between the expression of osteopontin and MMP-9 was analyzed. Results The positive expression rates of osteopontin and MMP-9 in gallbladder cancer tissues were significantly higher than that in normal gallbladder tissues and gallbladder adenoma tissues(P<0.05). The positive expression rates of osteopontin in patients of NEVIN Ⅳ，Ⅴstages were higher than that in patients of NEVIN Ⅰ，Ⅱ，Ⅲ stages)(P<0.05). The expression of osteopontin was positively correlated with the expression of MMP-9(P<0.05). Conclusion Both osteopontin and MMP-9 are significantly related to the metastasis of gallbladder cancer，and overexpression of both osteopontin and MMP-9 has a predictive value for metastasis and recurrence.
