Objective: RA is an autoimmune chronic systemic disease, characterized by inflammation, self-immune and the hyperplastic synovial pannus.

目的：类风湿关节炎(rheumatoid arthritis，RA)是一种慢性系统性疾病，其主要病理改变是滑膜炎和血管翳形成及其相关的血清组织中多种细胞因子、抗原抗体和粘附分子等的变化，而细胞因子是RA炎症和损伤的重要介质，对RA患者外周血及滑液中细胞因子改变已有大量研究，已证明多种细胞因子参与RA的病变过程。

There are many methods in dealing with this problem, such as naive factorization, QCD factorization approach, perturbative QCDfactorization approach, etc.

Results the scoresof obsessive-com pulsive, interpersonal sensitivity, depression, anxiety, hostility, paranoid ide ation, general symptomatic index and number of positive items were significantlyhigher than those of the domestic norm.the multiple linear stepwise regression revealed that the nervousness of epq; fa ther's refusal, rejection; father's warmth and understanding; feeling of oppress ion and cognition of future object entered regression equation.

结果 iad青少年强迫、人际关系敏感、抑郁、焦虑、敌对、偏执因子分、总均分及阳性项目数均高于全国青年常模。进入回归方程的变量有epq的n因子、embu的父亲拒绝否认因子和父亲情感温暖理解因子、压抑感及对未来目标的认识。

During each stage of angiogenesis, there are many different factors that take action synergically in temporal and spatial manner to the ongoing of vessel formation. Accorrding to their attribution to angiogenesis, these factors can be generally divided into positive and negative regulating factors.

在血管生成的各个阶段，有多种因子在时间和空间上协同作用，共同调节血管生成的进行，大体上可将这些调节因子分为正性调节因子和负性调节因子，正负调节的总体平衡决定着血管生成过程的启动与关闭。

The best tests for separating cirrhotic patients from normal controls, after allowance for interdependence among all the tests by a discriminate function analysis, were Digit Symbol and Trailmaking test.

因素分析提取了三个因子，因子1由威斯康星卡片分类测验各记分项目负荷，主要反映了心理过程的灵活性；因子2由第四例测验和相似性测验组成，主要反映了分析综合能力：因子3由积木图测验、数字符号测验、连线测验组成，主要反映了知觉-运动协调、视觉空间能力。

The activation of endothelial cell caused by TNF-α has detrimental effects on the vasculature. TNF-α can induce the increased apoptosis of gravid trophocyte. TNF-α has been showing up-regulate the vasoconstriction factors such as endothelin and down-regulate the vascular relaxing factors such as NO on the contrary.

肿瘤坏死因子α作为炎性分子，激活血管内皮细胞、间接影响血管舒缩功能，通过各种机制诱导胎盘滋养细胞凋亡增加，增加血管收缩因子并减少血管舒张因子的生成和释放，影响与脂类代谢相关的细胞因子。

Based on division of regions of a typhoon and characteristic scales of physical quantities done by Anthes,sets of equations governing different parts of the typhoon are derived with scale analysis and wave energy equations for each part are obtained with the WKB method. Discussions indicated that physical factors contributing to typhoon development are unconstant in all parts of the typhoon,respectively shown as vertical changes in vorticity and tangential wind for the core and outer mid-tropospheric area,...

利用Anthes关于台风的区域划分以及物理量特征尺度的结果，采用尺度分析方法导出了台风不同区域的控制方程组，又用WKB方法得到各区的波能量方程并进行了讨论，指出影响台风发展的物理因子在各区的异同点：各区都有非定常因子；同时，台风内核及外围中层对流层的因子有涡度和切向风的垂直变化，外围边界层有热成风及其偏差，外围流出层有水平位温梯度，这些因子与重力波适当的移向相配合，可使台风能量发展，强度增大。

The objectives of the study were to: 1 reveal the responses of vegetation and soil to degradation by investigating community characteristics and soil physic-chemical properties; 2 quantify the contributions of human factors and natural factors and the relationship among the factors by analyzing the variation of each factor in past decades; 3 understand the succession of fenced undegraded meadow, artificial pasture, semi-artificial pasture and degraded meadow, and to 4 provide suggestions for restoration and rehabilitation of the degraded rangeland in the region.

本项研究旨在通过对黄河源区退化高寒草甸的植物群落特征和土壤特征调查，揭示植物和土壤养分对土地退化的响应；对源区人口及牲畜数量和国内生产总值，气候变化特点等因子的分析，量化人为干扰因子和自然因子的贡献率以及各因子之间的数量关系；以及对草地退化驱动力分析以及原生草地植被封育、人工草地、半人工草地的自然演替变化规律的研究，为高寒草甸退化草地恢复与重建提供科学依据。

This process includes: platelet aggregation, sticking to damaged blood vessels, releasing vasoconstrictive agonists, activating or binding coagulation agents, and releasing platelet-derived growth factor and platelet factor IV.

该过程包括：血小板聚集，黏附于受损血管，释放血管收缩因子，激活或结合于凝固因子，最后释放血小板源性生长因子和血小板因子Ⅳ。

At 14 days after operation, VCAM-1 was still positive on the surface of uncovered endothelium, while more abundant expression was seen in the bottom of neointima near internal elastic lamina. Conclusions NF-κB activation and VCAM-1 expression participate in the inflammation of rat denudated artery.

核因子κB和血管细胞黏附分子1参与大鼠的主动脉损伤后的炎症过程；核因子κB的活化与失活成动态变化；血管细胞黏附分子1不同时间表达在不同的部位，核因子κB的活化与失活在血管细胞黏附分子1的表达与消退之前，核因子κB对血管细胞黏附分子1的表达起调节作用。
