Tumor necrosis factor-alpha may injure vascular endothelial cells by many ways, and the injury of vascular endothelial cella can accelerate the release of tumor necrosis factor-alpha, which can injure the vascular endothelial cells again.

肿瘤坏死因子α可通过多种途径损伤血管内皮细胞，血管内皮细胞的损伤又促使肿瘤坏死因子α的释放，再次损伤血管内皮细胞，两者互为因果，形成恶性循环。

One hundred consecutive eyes with endothelial failure were entered into a prospective study of endothelial keratoplasty, and the donor central endothelial cell density was recorded postoperatively at 6 months (n = 98), 12 months (n = 96), and 24 months (n = 85) and then compared with the preoperative eye bank measurements.

实验方法：选取角膜内皮功能失代偿的100只眼作为角膜内皮移植术的前瞻性研究对象，分别于术后6月（n = 98）、术后12月（n = 96）、术后24月（n = 85）测量供体角膜中央内皮细胞密度，并与术前所测眼库的眼角膜中央内皮细胞密度值进行比较。

The mechanism probably is that Pishang can inhibit the growth, movement and adheresion to extracellular matrix and endothelial cell of liver tumor cells, up-regulate the expression of nm23, down-regulate the expression of CD44, MMP-2, and inhibit the tumor neovascular by supressing the vascular endothelial cell, down-regulating the expression of VEGF, damaging the primitive mesenchymal cells and inhibiting neovascular gemmation.

砒霜具有明显的抗肝癌细胞作用，并有一定的抗侵袭与转移作用，其机制可能与其能抑制肝癌细胞增殖、迁移、阻止肝癌细胞与细胞外基质和内皮细胞粘附、上调肿瘤转移抑制基因nm23表达、下调肿瘤侵袭分子CD44、MMP-2表达以及通过抑制内皮细胞增殖、下调VEGF表达、损伤间充质细胞、阻止新生血管芽生等途径从而抑制肿瘤新生血管形成有关。

Objective To investigate the alteration of vascular endothelial cells and circulation endothelial cells damage in acute-phase Patients with Coronary Heart DiseasConstruct technology platform of vascular endothelial cells damage, in order to provide new theory evidence and laboratory indicatrix of earlier-phase prophylaxis and diagnosis for nosogenesis、development、turnover of Coronary Heart Disease Methods 65 acute-phase Patients with Coronary Heart Disease of preparing for operation of heart...

目的探讨冠心病患者急性期血管内皮细胞、循环内皮细胞损伤的特点，构建检测内皮细胞损伤的技术平台，为冠心病的发生、发展、转归，甚至早期预防及诊断提供新的理论依据和实验室指标。

To begin with, the adhesive experimental model between SMMC-7721 cells and HUVECs was established in this paper, then expression of integrin β〓 in SMMC-7721 cells was determined by flow cytometer, finally, adhesive mechanical properties of different cell cycle SMMC-7721 cells to collagen Ⅳ were studied by micropipette aspiration technique.

本文首先建立了肝癌细胞与内皮细胞粘附力分析的实验模型，接着应用流式细胞技术检测肝癌细胞上integrin β〓的表达，最后研究了不同细胞周期肝癌细胞与内皮细胞的粘附力学特性。

HA increased level of NO by activating NOS after combining with H〓 and H〓 receptors; and on the one hand 5-HT caused brain microvessel endothelial cells constracting strongly, made the tight joint opening, increased the permeability of BBB, and on the other hand 5-HT increased the quantity of pinocytosis vesicle in endothelial cells and enhance the permeability of BBB after comining with 5-HT〓 receptor.

HA与H〓和H〓受体结合，激活NO合成酶，使NO含量增多而诱发BBB通透性增加；5-HT与5-HT〓受体结合，一方面引起脑微血管内皮细胞强烈收缩，使内皮细胞间的紧密连接开放，BBB通透性增高，另一方面可引起内皮细胞转运小泡增加，BBB通透性增高。

Preliminary study revealed the devascular effect of PYM correlated with the inhibitory of vascular endothelial cells.

一、PYM抑制人脐静脉内皮细胞生长的体外研究目的通过体外实验观察PYM对人脐静脉内皮细胞株一一一石CV304细胞生长、增殖和凋亡的影响，以证实PYM对血管内皮细胞的抑制作用及了解相关的影响因素。

Results ec was cultured and subcultured successfully. vascular endothelial cells show slabstone appearance enchased arrange under phase contrast microscope. the growth appearance was showed under sem. some dispersive high electron density of rod type weible palade body were seen under tem.

结果 培养出血管内皮细胞并传代，倒置显微镜下血管内皮细胞呈"鹅卵石"形态，扫描电镜显示"铺路石"样生长，透射电镜可见内皮细胞特征性w p小体，免疫组织化学鉴定ⅷ因子。
