It is possible that atypical perilobular hemangiomas or atypical hemangiomas are precursors to angiosarcoma, but this relationship remains to be demonstrated.

不典型小叶周围血管瘤或不典型血管瘤可能是血管肉瘤的前驱病变，但这种相关性尚需要进一步证实。

Methods\ ELISA (enzyme\|linked immunosorbent assay) was used to determine serum VEGF concentration of 15 patients with proliferative hemangioma, 6 with involuted hemangioma, 6 with vascular malformation and 8 infants of the control group.

Results: Various extent of gyrus-like or banded calcifications were showed in cortex of 8 all cases, cerebral hemisphere atrophy in 4 cases and thickened skull in 3 cases on the diseased side were accompanied. Ocular hemangioma of choroid and choroids plexus enlargement of lateral ventricle were found in one case. The clinical symptoms and signs of correspondence were found.

结果：8例脑颜面血管瘤综合征均有脑皮层不同程度的脑回样或条带状钙化，4例伴病侧大脑萎缩，3例伴病侧颅板增厚，1例合并眼部脉络膜血管瘤和侧脑室脉络丛增大。8例均出现与CT表现相对应的临床症状和体征。

Our experiments proved that VEGF have relationship with proliferation and involuting of hemangiomas.

结果显示，增生期血管瘤组织中P53着色的肥大细胞数目为29.64±2.67/HPF，消退期为14.87±4.43/HPF，血管畸形组织中为1.33±0.6/HPF.F检验结果表明：在增生期、消退期血管瘤及血管畸形组织中P53着色的肥大细胞数目有显著性差异（P.05）。

The expressions of Bax and TGFβ1 in 50 children cases of dermal hemangioma which were in proliferative phase or in involuting phase were detected by HE staining and immunohistochemical method. We also analysized the difference between the different phases of hemangioma , and try to find out the role of Bax and TGFβ1 in hemangiomatous proliferation and regression .

采用HE染色和免疫组织化学方法检测50例小儿皮肤血管瘤增生期、退化期Bax、TGFβ1的表达水平，并分析它们在不同时期血管瘤中的差别，近而探讨Bax、TGFβ1在血管瘤增生、消退中的作用。

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。

Results: In hemangioma at proliferating phase, hemangioma at involuting phase, and normal skin, the expressions of TRAIL were 1.26±0.56, l.74±0.68, and 1.00±0.23, PI was (40.98±12.02)%,(20.05±3.67)% and (15.64±4.01)%, AR was (11.96±4.02)%,(20.29±3.53)% and (6.61±1.29)%, respectively. There were significant differences among the 3 groups in the 3 parameters.

结果：增生期血管瘤、消退期血管瘤和正常皮肤组织中TRAIL蛋白的表达分别为1.26±0.56，1.74±0.68，l.00±0.23，PI分别为(40.98±12.02)%，(20.05±3.67)%，(15.64±4.01)%，AR分别为(11.96±402)%，(20.29±3.53)%，(6.61±1.29)%。3组间以上3指标两两比较，差异均有统计学意义。

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。
