前言 类风湿关节炎(rheumatoid arthritis，RA)是一种常见的以关节组织慢性炎症性病变为主要表现的全身性疾病。

In this study, based on the Rnl, extinction coefficient k, transition coefficient of canopy layer stomatic resistance K', aerodynamics resistance ra and rc calculated with the data of Rn, LAI, rsi, the daily transpiration variation of Picea purpurea, Larix principisrupprechtii, Hippophae rhamnoides ,Betula platyphylla and Populus cathayana were studied in Datong County, Qinghai Province. Comparing with the practical transpiration variation measured by Li1600 Steady Porometer, the relative error of this model was less than ±15%, and the results were stabilized and tested by precision analysis.

本研究通过对Rn、LAI、rsi的实地观测，确定了林冠截流净辐射、消光系数、冠层阻力转换系数、空气动力学阻力和冠层整体气孔阻力，对青海大通地区紫果云杉、华北落叶松、沙棘、白桦和青杨的日蒸腾过程进行了模拟，与用快速称重法订正的Li1600稳态气孔仪实测蒸腾结果对比，模拟的相对误差在±15%以内；模型敏感性分析发现，温度、LAI以及rsi是决定模拟结果的主要参数，模型对各参数变化反应不敏感。

Objective:(1) To compare the sensitivity, specificity, and positive prognosticative value in the diagnosis of rheumatoid arthritis by examining antifilaggrin antibody, anti-cyclic citrullinated peptide antibody and rheumatoid factor respectively simultaneously.

目的：①检测类风湿关节炎病人血清抗聚角蛋白微丝蛋白抗体、抗环瓜氨酸肽抗体及类风湿因子，比较单独检测和联合检测对RA诊断的敏感性、特异性、阳性预测值。

METHODS: 124 patients with RA were assessed at baseline and after 10 years with inflammatory markers calprotectin, C-reactive protein (CRP, erythrocyte sedimentation rate, serological variables antibodies to cyclic citrullinated peptide (anti-CCP, IgA rheumatoid factor and IgM RF and radiographic and clinical assessments of joint damage hand radiographs and Rheumatoid Arthritis Articular Damage (RAAD score.

我们对患者在试验基线时和10年后分别进行了评估，测定其炎症标志物（钙卫蛋白、C反应蛋白CRP、红细胞沉降率ESR）水平，血清学变量（抗环瓜氨酸肽抗体Anti-CCP、IgA风湿因子RF、IgM风湿因子）水平，以及关节损害的放射影像学表现和临床表现（手部的X线片、风湿性关节炎关节损害RAAD评分）等。

Therefore, we selected common species of Ranunculaceae. comparative primordial plants in Alpine Meadow at Eastern QinghaiTibetan Plateau, and studied the reproductive strategies, such as reproductive allocation, especially sex allocation, to understand how the plants adapt the environmental conditions. The results showed:(1) At higher altitude, the self-incompatible plant, such as Trollius ranunculoides tended to become limited by pollination rather than by nutrient availability, while the self-compatible plants, such as Anemone rivularis and A. obtusiloba seemed not to be limited by pollen availability, which suggested that ability of self pollination for alpine plants may be a mechanism of reproductive assurance.(2) Influences induced by high altitude on the reproduction of these species occurred on different reproductive characters, which suggest species-specific adaptive strategies. The influences are dependent on plant size to some extent.

因此，我们选择在青藏高原东部的高寒草甸，以比较原始的植物类群—毛茛科植物为研究对象，选择一些常见种探讨其繁殖对策，如繁殖分配和性分配问题，试图揭示这些植物如何适应环境条件，最后的结果表明： 1高寒草甸高海拔区，自交植物(如小花草玉梅A.rivularis和钝裂银莲花A.obtusiloba)的繁殖不受花粉限制，而完全异交植物(毛茛状金莲花T.ranunculoides)的繁殖受花粉限制，表明高海拔地区植物的白花授粉能力可能是一种繁殖保障机制，能够避免恶劣环境对植物有性繁殖的不利影响； 2海拔高度对植物的影响因种而异，不同的物种受影响的繁殖性状不同，即使同属亲缘种间也存在差异，表明不同物种对相似环境压力的适应对策不同；而且，海拔高度对植物的影响在一定程度上依赖于植物个体大小，说明植物通过调整其个体大小与繁殖性状的关系来适应环境梯度的变化； 3植物花期和果期的繁殖分配并不完全随海拔升高而减小(只有小花草玉梅的果期RA随海拔升高而减小30％)，与Iwasa和Cohen的预测不完全一致(他们认为繁殖分配随生长季缩短而减小)。
