血管瘤的

Presented with early artery enhancement and immediate wash out ,Two cases presented with wash in quickly and wash out slowly .The enhancement pattern of 36 liver metastatics cases was divided into the little blood provides group and the much blood provides group . The 5 cases of haemangioma were enhanced centripetally in portal phase and washed out after several minutes without arterial enhancement.

通过造影后的表现还可明确提示以下几个方面：（1）肿块内的坏死区；（2）在延迟相发现了肝内小转移灶，从而改变了临床治疗方案；（3）滋养动脉的显示；（4）门脉内栓子的鉴别诊断。36个转移性肝癌病灶分为少血供转移癌组和多血供转移癌组。6例肝血管瘤中5例均表现为向心性环行持续缓慢充填，另一例9mm的小血管瘤表现为完全、快速向心填充。

The testing of pcna may be helpful in the diagnosis and treatment of hemangioma and vascular malformation.

pcna在血管瘤中的表达与其分期明显有关；pcna的检测有助于血管瘤与血管畸形的鉴别诊断及治疗。

"Immature hemangioma (hemangioma simplex, strawberry mark), a reddish nub of dilated small blood vessels, enlarges in the first six months and may become ulcerated but usually recedes after the first year."

发育不全的血管瘤(亦称单纯性血管瘤或草莓状痣)，是由扩张的小血管聚集而成的红色小肿块，损害一般在婴儿六个月左右达到最大，有时破溃，一岁后可逐渐缩小。

Abstract］ Objective To explore the diagnostic value of MRI in encephalofacial angiomatosis. Methods The MRI findings were retrospectively studied in 5 cases of encephalofacial angiomatosis proved by histological examinations,its MRI data, clinical performance and pathogenesis were summarized and analysed.

目的 探讨磁共振成像对脑颜面血管瘤病的诊断价值方法收集5例经临床和手术证实的脑颜面血管瘤病，对其磁共振资料、临床表现和发病机制进行回顾性的总结和分析。

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。

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。

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。
