Objective To explore a method of repairing large area skin and soft tissue defects in legs and feet with free vascularized flaps, to analyze why blood vessel crisis occurs and how to prevent it.

目的 探索应用吻合血管的游离皮瓣，修复小腿及足部大面积皮肤软组织缺损的治疗方法，分析皮瓣发生血管危象的原因，提出预防血管危象产生的方法。

Blood oxygen saturation monitor is a useful monitor means,which is convinious,operated simply,no trauma and no pain.It is effective parameter that can be used to evaluate blood vessel restoration effect.If continuous observation is done,it can help to discover blood vessel crisis and forecast result of repaired blood vessel.

血氧饱和度的监测是一种使用方便、操作简单、无创伤、无痛苦的监测方法，是辅助评价血管损伤后修复效果的良好参数指标，连续的观察有助于早期发现血管危象的发生及预测修复血管的转归。

Objective:To evaluate the clinical s ignificance of the expression of vascular endothelial growth factor, estro gen receptor and progesterone receptor in invasive ductal carcinoma of breast.

血管生成是恶性肿瘤迅速增殖、转移、扩散的主要条件之一，其中血管内皮生长因子( Vascularendothelial growth factor VEGF)对实体瘤的血管生成作用至关重要。

METHODS: The presence and number of recently developed extra-articular manifestations and a weighted EAM score, as well as the levels of serological markers, were compared between 31 patients with RA with histologically proven vasculitis and 50 patients with RA in whom vasculitis could not be documented histologically. The following markers were evaluated: circulating immune complexes, complement components C3 and C4, class-specific rheumatoid factors, antineutrophil cytoplasmic antibodies, antinuclear antibodies, antiendothelial antibodies, circulating intercellular adhesion molecule-1 and -3, circulating vascular cell adhesion molecule and E-selectin, cellular fibronectin, von Willebrand factor antigen, and C reactive protein.

对比组织学上已证实有血管炎的31例 RA 例和组织学上无血管炎的50例 RA 患者间的临床及血清学标记物，这些资料包括最近发生的关节外表现数量、关节外表现加权得分、循环免疫复合物、补体 C3和 C4、类风湿因子（ IgM-RF，IgG-RF，IgA-RF ）、抗中性粒细胞胞浆抗体、抗内皮细胞抗体、循环细胞间粘附分子-1和-3、循环血管内皮粘附分子和 E-选择素、细胞纤连蛋白、假性血友病因子抗原（ von Willebrand factor antigen ）及 C-反应蛋白。

Glyceryl trinitrate induced dilatation: GTN, high sensitive C reactive protein, tHcy, serum folate, red cell folate and lipids.

干预前、后分别检测血管内皮功能、血管平滑肌功能（硝酸甘油介导的血管平滑肌舒张GTN）、高敏C反应蛋白、血浆总高半胱氨酸、血浆红细胞叶酸盐和血脂。

Hlubocka Z, Umnerova V, Hellers, et al. Is mild essential hypertension without obvious organ complications and rish factors associated with increased levels of circulating markers of endothelial dysfunction, effect of ACE inhibitor therapy.

当心衰发生和发展时，机体交感神经和肾素-血管紧张素系统激活，AngⅡ生成明显增多，AngⅡ与血浆内皮功能失调密切相关，能够刺激血管内皮细胞衍生ET-1释放，引起血管张力升高［6，7］。

When no angiogenesis, solid tumor growth will Be inhibited so obviously that it is limited to carcinoma or tiny metastasis of several hundred micra; on the contrary, if having angiogenesis, tumor will grow rapidly, whacs more, its nature of soakage and metastasis will be enhanced greatly.

新生血管为肿瘤的生长、转移提供氧和营养物质，在无新生血管生成时，实体肿瘤的生长明显被抑制，只局限于原住癌或几百个微米的微转移；而一旦新生血管长入，肿瘤将迅速生长，且浸润和转移的能力大大加强。

However, when the 3 individual outcomes (myocardial ischemia, stroke and peripheral vascular disease) were evaluated separately, only the relative risk reduction for peripheral vascular disease was effectively reduced:(stroke 7.3%, MI _3.7% and PVD 23.8%) The trialists attributed the discrepancy in the stroke group to the heterogeneity of the disorder, a correct but frequently overlooked observation.

然而，当我们分别对这三类患者结局（心肌缺血，卒中和周围血管病）单独分析时发现，仅周围血管病患者的相对危险降低率减少有显著意义（卒中组7.3％，心肌缺血组-3.7％，周围血管病组23.8％）。

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。
