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.

Immunohistochemical technique for factor Ⅷ-related antigen was used to identify that the cells which expressed P57(superscript kip2) were endothelia.

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P57(上标 kip2)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P57(上标 kip2)的细胞是血管内皮细胞。

Some cell dropped into the cavity and became free. Thrombosis or part organization could be seen. The internal elastic layer became thin, disappear or broken. In internal and middle layer existed fibroblasts, fibrocytes and collagen. Some of the wall indicated hyaline change, soomth muscle cell decreased greatly. The massive inflammatory cells invaded the middle and external layer. There were many foam cells in the capsule tissue. Cytoplasm was filled with fatty tissue and cholesterol. some cavities were full of thrombosis. Some thrombosis was fibrosis, the bottom was organization. The surface of the thrombosis existed red blood cell and librae.(2)Elatic fibrila staining: the internal elastic menbrane almost completely disappeared, the intact internal elastic menbran could be seen in the new small vessels.

动脉瘤管壁厚薄明显不均，全层或局部区域显著变薄向外膨出，内皮细胞空泡变性或坏死脱落，部分内皮细胞剥离并突入管腔成游离状，可见血栓形成及部分血栓机化；内弹力板变薄、消失或突然中断；在内膜及中膜部位主要为纤维母细胞、纤维细胞和大片胶原；部分动脉瘤壁呈均质状玻璃样变，平滑肌细胞明显减少；中膜和外膜可见大量的炎性细胞浸润；瘤壁组织有纤维母细胞、纤维细胞、大片胶原成分及较多泡沫细胞，胞浆内充满脂类物质及胆固醇结晶；部分动脉瘤腔内充满血栓，有的血拴已经纤维化，血栓基部机化，血栓表面有红细胞和纤维素。

No US-pin plastic treatment therapy, a comprehensive alternative to traditional plastic injection of the United States (with the needle and micro-needle) is efficient, non-invasive and safe,"mesoderm into beauty therapy" is the latest technology of water use and water channel protein electrophoresis principle of development Note the infiltration hole electric technology to non-needle injection principle, the use of "point to a plane," AMD permeation technology in skin electroporation Act under the influence of pulsed current stimulation, so that pores have a physical reaction to the rapid spread in two seconds 650-800 of fine pores, forming an instant electronic delivery channels of nutrition, nutrition Note dialysis therapy immediately with electrophoresis, soft laser stimulation and ice, etc., in the most secure and fast, the skin will be required for nutritional products , 99% transmitted to the basal cells, and can be stored as long as 72 hours, the skin smooth and more compact, creating a perfect Beautiful Skin.

B。电穿孔技术：直接作用于皮肤，瞬间增强皮肤组织的可渗透性。在电击的作用下，细胞的脂质二重层上形成电击孔。在电击孔形成的同时，使得原先无法被细胞吸收的亲水性分子能够穿透并进入细胞内部。电击孔一旦形成，则根据电击的长度，在数秒种至数分钟之内保持打开状态。C。电渗透技术：电渗主要作用于将要分散的物质分子，帮助其顺利穿透并进入肌肤内部，性质相同的电荷相互排斥，因此对正极的营养分子施加正电流，可将营养分子推入皮肤组织。此时，中性分子也一道穿透并进入肌肤内部。

Detecting each marker and cmparison the location of sequential tissuesection could determine the area loceation relationship of the markers, but it is difficulte to determine their correlation intra-cells exactly. No report of detecting virus genome and antigenes on a one section with triple staning techniques exists in the lit erature. in this report. by combining immunohistochemistry and in situ hybridization (with dioxigenin labelled HBV DNA probe), a triple staining technigce was established. With this technic, on one formalin-fixed and paraffin embeded section, HBV DNA, HBsAg and HBcAg were determinated one after the other.

各个细胞内病毒的复制和表达水平以及与肝细胞病变的关系，是乙型肝炎发病机理研究的一个重要方面：目前常用的在系列切片上对各标志物分别检测，比较观察的方法，一般只能大致了解各待检物在某一区域的定位关系，很难准确地了解它们在同一细胞内的关系：国内外尚未见有在同一张切片上三重标记染色检测病毒核酸及其多种抗原的报道：本文结合免疫组织化学ABC法及地高辛配基标记HBV DNA探针原位杂交，建立三重标记染色技术：在一张福尔马林固定石蜡包埋肝组织切片上先后检测，同时显示HBV DNA、HBcAg和HBsAg。

The results showed that the plant had the character of damp-inhabiting, the cutical on the epidermis of stem and leaf is rather thin but without wax-layer, its stomata protrude clearly on the lower surface of leaf, the rate of palisade parenchyma and spongy parenchyma is rather low and the cortex is well developed in root.

The results of this reseach showed that administration of SF intracolonically had protective effect on the colon injury in the rat model of colitis induced by acetic acid enema, which was probably due to the mechanism of antioxidation, inhibition ofarachidonic acid metabolis and platelets activation, administration of SF intracolonically also showed protective effect on the colon injury in the rat model of colitis induced by trinitrobenzene sulfonic acid and ethanol, which was probably due to antioxidation and inhibition of macrophages activation.

实验研究表明，大鼠分别经乙酸、TNBS和乙醇处理后均出现典型的结肠炎症状，给药后分别评价结肠粘膜损伤指标、结肠组织病理变化，检测结肠组织炎症指标、结肠组织氧化损伤指标及主要炎性细胞因子改变；实验结果：阿魏酸钠对大鼠乙酸性结肠炎结肠粘膜损伤具有缓解保护作用，其机制可能与直接抑制炎症结肠粘膜花生四烯酸代谢过度，抑制血小板活化，清除大量氧自由基有关；阿魏酸钠对大鼠TNBS性结肠炎粘膜免疫损伤亦具有缓解保护作用，其机制可能与抗氧化，抑制结肠巨噬细胞活化有关。

The thoracic duct endothelia in vitro could remain their biological properties, and could be made a tool for studing their functions and cancer metastasis mechanism by lymphatics. The positive expression of VEGF-C in cancer cells was correlated with cancer development, it seem to be that VEGF-C induce lymphoangiogenesis through its receptor Flt-4. The Flt-4 expression of lymphatics in cancer tissues was assosiated with cancer development, it is considered that there are new lymphatics in cancer tissues.

体外培养的大鼠胸导管内皮细胞可以保持体内淋巴管内皮细胞的生物学特性，可作为研究大鼠淋巴管内皮细胞功能和进一步研究癌转移机制的体外实验材料；大鼠大肠癌组织腺体的VEGF-C表达与肿瘤进展有关，推测其通过受体Flt-4诱导淋巴管生成；Flt-4在淋巴管的阳性表达随肿瘤进展增多，推测在癌组织内存在淋巴管的新生。

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。
