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。

It is found to relate to atherosclerosis, increasing tension of coronary artery, coronary vasospasm, coronary thromboses and vascular restenosis after percutaneous transluminal coronary angioplasty that endothelium reduce generation and re lesae of EDRF/NO.

随着内皮分泌功能的发现，人们逐渐认识到内皮不仅仅是具有单纯弥散屏障作用的细胞成份，它还有：1、调节血管舒缩；2、防止血栓形成；3、大范围的激素调节；4、促使或抑制内皮本身和血管平滑肌细胞的增生；5、调节儿茶酚胺、血小板产物的代谢和失活等作用。

It is found that inhibition of PARP may effectively protect endothelium from diabetic vascular diseases.

抑制PARP可有效防止内皮细胞的损伤，预防甚至逆转糖尿病血管并发症，对PARP的干预可能成为防治糖尿病血管并发症的一个新靶点。

The reticulated vessel which has large cavity has thicker wall due to more elastic fibers and more smooth muscles and its endothelium is cuboidal epithelium which has rotundity karyons. But the reticulated vessel which has small cavity has thinner wall due to less elastic fibers and less smooth muscles and its endothelial cells are flat epithelial cells which have long-shuttle-shaped karyons. In some regions, the ducts are very small in diameter and thin of wall, and they become blood sinus in the end.

管腔大者，管壁厚，弹性纤维、平滑肌纤维多，内膜靠腔面内皮细胞多成立方状，细胞核端位近圆形；管腔小者，管壁薄，弹性纤维、平滑肌纤维少，内皮细胞扁平、排列稀疏，胞核长梭形；一些区域管径极小，管壁极薄，成为开放的血窦，只允许一个血细胞通过。

These results suggest that ONOO- causes weak relaxation in pulmonary artery, which is down regulated by endothelium and is of tachyphylaxis.

结果表明， ONOO-对肺动脉的舒张作用较弱，此作用受到内皮细胞的抑制性调节并有快速去敏性。

The results showed that (1) all the arteries tested had tachyphylaxis to peptidergic agonists;(2) the desensitization of the arteries tested to catecholamines was uneasy except BA;(3) the desensitizations to AⅡ, AVP and PE were homologous;(4) the endothelium-EDRF -cGMP pathway had no contribution to the tachyphylaxis of PA to AⅡ and AVP;(5) membrane receptor cycling (internaliation and re-insertion) contributed only in part to homologous desensitization;(6) there was no change in the function of voltage-dependent Ca〓 channel during desensitization to AⅡ and AVP;(7) some changes in G protein occurred during homologous desensitization;(8) the most surprising finding was that the caudal arterial smooth muscle of stroke-prone spontaneously hypertensive rat showed tachyphylaxis to α〓-adrenoceptor agonist PE, while the tachyphylaxis of pulmonary artery of SHR was not changed compared with that of Wistar rat.

脱敏是消除效应的一种有效方式。因此，研究不同血管对不同激动剂脱敏的差异及阐明脱敏的机制，有助于阐明血管活动个性化的机制。研究表明：血管对肽类激动剂的脱敏方式为快速脱敏，而对儿茶酚胺类激动剂不易脱敏；血管对肽类激动剂和儿茶酚胺类激动剂表现为同源脱敏；内皮-NO-cGMP通路不参与肺动脉对AⅡ和AVP的快速脱敏；用PAO抑制膜受体的内在化只能短暂抑制脱敏的发展，提示用膜受体数目的下调说不能完全解释同源脱敏；血管对AⅡ和AVP脱敏后VSMC细胞膜电压依赖性钙通道功能无改变；CA对AVP脱敏后GTPγS的量-效曲线下移，说明有G蛋白的变化，但这种变化并非G蛋白的亲和性改变；SHRsp之CA平滑肌对AⅡ和AVP的快速脱敏并未减弱，但对PE却表现为快速脱敏，这是我们首次发现的一个非常有趣的现象。
