结果 在血管瘤增生期、血管瘤退化期、血管畸形、正常皮肤组织中MMP-2表达的阳性率分别为32%、12%、8%、5%，血管瘤增生期组明显高于其它3组(P.05)；其差别具有显著性意义。

The positive expression rates of Tissue Inhibitors of Metalloproteinase-2 protein in the cases of involuting groups were significantly higher than those in proliferating group and vascular malformation groups and normal skin group (P.05). Its difference was significant. Conclusions: Matrix MetallProtinase-2 and Tissue Inhibitors of Metalloproteinase-2 may play an important role in the pathogenesis of hemangiomas through angiogenesis. They may have no effect on vascular malformation and normal skin

血管瘤退化期，TIMP-2表达明显升高，说明 TIMP-2与血管瘤纤维化、消退有关，其机制可能是一方面通过抑制MMP-2介导的基底膜降解而在内皮细胞迁移、聚集中起作用，另一方面直接抑制内皮细胞的增殖及迁移，使内皮细胞高频率调亡，细胞外基质增多，组织出现纤维化，最终导致血管瘤的退化。2、血管畸形和正常皮肤小血管中MMP-2和TIMP-2不表达或表达较弱，说明血管畸形和正常皮肤小血管中并不存在异常的血管生成，据此可以对血管性疾病进行分型、分期，并指导临床治疗。

objective:to investigate the expression and significance of rb in the occurrence, development and regression of infantile hemangiomas.methods:the expression of rb was examined in the proliferative stage and catagen of human hemangiomas and normal skin tissues by using immunohistochemical technique.immunohistochemical technique for factorⅷ-related antigen was used to prove that the cells which expressed rb were endothelium.image analysis system was applied to measure the expression level of rb at different stages of hemangiomas and in normal skin tissues.results:the expression of rb was significantly lower in proliferating hemangiomas than that in involuting hemangomas(p.05).conclusion:rb might play an important role in the regression of human hemangioma endothelial cells and anti-angiogenesis.
