查询词典 hemangiomas

METHODS: Sixty two cases of specimens collected in operation were studied by in situ RT PCR, of which 50 cases were hemangioma: 26 cases proliferating hemangioma and 24 cases involuting hemangioma, and 12 cases were venous vascular malformation. The expression of Ang2 mRNA and Tie2 mRNA in hemangiomas and venous vascular malformation were detected by in situ RT PCR.

采用原位RT PCR方法，对临床收集的62例手术切除的先天性皮肤血管标本（其中增生期血管瘤26例，消退期血管瘤24例，静脉型血管畸形12例）进行Ang2 mRNA， Tie2 mRNA表达水平的检测。

PCR方法，对临床收集的62例手术切除的先天性皮肤血管标本（其中增生期血管瘤26例，消退期血管瘤24例，静脉型血管畸形12例）进行Ang2 mRNA， Tie2 mRNA表达水平的检测。

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。

Methods: The expression of P57(superscript kip2) was examined in proliferating, involuting human hemangiomas and normal skin tissues by using immunohisto-chemical technique. Immunohistochemical technique for factor Ⅷ-related antigen was used to identify that the cells which expressed P57(superscript kip2) were endothelia.

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P57(上标 kip2)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P57(上标 kip2)的细胞是血管内皮细胞。

The results show that cure rate and total utility rate of curative effect are relative with age in those patients with strawberry hemangiomas ,who should be treated early,and not in those of naevus flammeus.

结果发现治疗的总有效率和痊愈率在草莓状血管瘤组与年龄有关，早期治疗效果较好；而鲜红斑痣组则和年龄无关。

Strawberry hemangiomas are real tumors and naevus flammeus are vascular malformations.

由于草莓状血管瘤属真性血管瘤，而鲜红斑痣属血管畸形，二者的血管内皮细胞存在差异，两种疾病对脉冲激光治疗反应的不同可能与此有关。

The parenchymal hemangiomas consist of honeycombed vascularspaces with stagnant blood flow.This slow flow within the cavernoushemangioma often thromboses,resulting in fibrous organization and calcification.Their feeding artery and draining vein are small,often invisible angiographically.

脑内的海绵状血管瘤由于缺乏明显的供血动脉，病变内血流缓慢，易形成血栓而导致病变的机化和钙化，加之病变与周围脑组织界限明确，除位于脑干的病变外，手术切除相对比较容易，手术后并发症和死亡率较低，预后良好。

"Second, both solid tumors and ascular anomalies (e.g., hemangiomas, port-wine stains) are known to hae increased expression of angiogenic proteins, including ascular endothelial growth factor and basic fibroblast growth factor."

&第二，已知实体瘤和脉管异常（例如血管瘤、葡萄酒色痣）存在血管原的蛋白表达增加，包括血管内皮生长因子和碱性成纤维细胞生长因子。&

METHODS. Our study population comprised 49503 US children whowere born between 1959 and 1968. Birthmarks were documentedas definite or suspected during the first year through historyor medical examinations and included hemangiomas (port-wine,strawberry, or cavernous), pigmented nevi, lymphangiomas, andcafé-au-lait spots.

研究人员调查的资料来源为出生于1959到1966年的49，503位儿童，若有胎记的儿童，在其出生后一年内就被详载于文件中，这些胎记的型式包括：鲜红斑痣（port-wine stains）、色素痣、草莓胎记以及咖啡牛奶斑(Cafe-au-lait spot)等。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
