Methods: The expression of P21 and fasL in proliferating and involuting human henmangioma and normal skin tissues was detected and compared by using immunohistochemistry. Image analysis was applied to measure the expression level of P21 and fasL in different stages of human hemangioma and in normal skin tissues.

采用免疫组化SP法检测人血管瘤组织中增生期、退化期及正常皮肤组织血管内皮细胞中P21ras、与FasL的表达水平，利用计算机成像分析系统检测不同时期皮肤血管瘤与正常皮肤组织P21ras、与FasL的平均光密度及其阳性面积率。

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.

目的：探讨rb蛋白在血管瘤发生、发展及退化过程中的表达状况及其意义。方法：采用免疫组织化学方法检测人皮肤血管瘤增生期、退化期及正常皮肤组织中rb的表达水平，并结合第ⅷ因子相关抗原的免疫组织化学染色证实表达rb的细胞是血管内皮细胞。利用计算机图像分析技术测量不同时期血管瘤组织和正常皮肤组织rb表达的积分光密度和面积。结果：增生期血管瘤内皮细胞rb表达水平低于退化期，差异有显著性（p.05），退化期血管瘤内皮细胞rb表达水平与正常皮肤组织相比，差异有显著性（p.05）。结论：rb通过抑制血管瘤内皮细胞增殖和血管生成而在血管瘤的退化过程中起重要作用。

Objective: The aims of our research are ① to filter candidate Wnt genes which are important for maintenance of normal hESCs or resulting in karyotypic change through analysis of Wnt genes of differential expression in human and mouse feeder cells and hESCs during culture of normal or abnormal karyotype hESCs.② to research the function of Wnt9a that RNAi for human Wnt9a were performed.
