ABSTRACT
Objective To investigate the expression of osteopontin (OPN)and matrix metalloproteinase-2(MMP-2)in hepatic alveolar echinococcosis(HAE) ,and explore the role of OPN and MMP-2 in the invasion and metastasis of HAE infection .Methods Expression of OPN and MMP-2 in HAE tissues from 69 patients within12 nomral liver tissues .HAE were detected using SP im-munohistochemical technique ,the correlation between OPN and MMP-2 expression and clinieopahtologic features was analyzed .Re-sults OPN and MMP-2 mainly distributed in the cyst wall about granuloma inflammatory cells of HAE and and the peripheral por-tion of stromal cell and liver cells ,the positive expression rate in HAE focus and normal liver tissue at the juncti-on of the invasive margin the most obvious .The results showed that the positive rates of OPN and MMP-2 in HAE tissue were 72 .5% (50/69)and 59 .4% (41/69) ,respectively ,and in normal liver tissue were 16 .7% (2/12) and 8 .3% (1/12) ,respectively .The positive rates of OPN and MMP-2 in HAE were significantly higher than those in normal liver tissue(P<0 .01) .The positive rates of OPN and P21 in HAE tissues with metastasis were 86 .8% (33/38)and 76 .3% (29/38) ,respectively ,which were significantly higher than those without metastasis of OPN and MMP-2 positive expression rate of 54 .8% (17/31) and 38 .7% (12/31) ,(P<0 .01) .The positive expression of OPN and MMP-2 were not related to the size of tumor bulk ,HBsAg ,gender ,age and nation of tumor .Rank correlated analysis showed that OPN and MMP-2 were positive correlated(r=0 .36 ,P<0 .01) .Conclusion OPN and MMP-2 mainly distrib-utes in the cyst wall about granuloma inflammatory cells of HAE and and the peripheral portion of liver cells ,the positive expres-sion rate in HAE and normal liver tissue at the junction of the invasive margin the most obvious ,which might be invasion and me-tastasis of HAE .
