Brane, such as synoviocytes, macrophages, osteoclasts and TNF-αvv acts on different kinds of cell in synovial memchondrocytes, which can produce metalloproteinase,collagenase, stromelysin and so on, further induce pannus formation, joint inflammation, bone erosion and cartilage degradation.

TNF-α可作用于RA关节组织中的滑膜细胞、巨噬细胞、软骨细胞和破骨细胞，使这些细胞活化，产生金属蛋白酶、胶原酶、基膜溶解酶等，导致局部炎症反应和血管翳形成，进一步引起软骨破坏和骨侵蚀。

Morning stiffness, symmetric arthritis, RF positivity, ESR, CRP and synovial hyperplasia, enhanced pannus, bone marrow edema and bone erosion have certain differentiating diagnosis value between early RA and non-RA.

以晨僵、对称性关节肿胀、ESR增快、RF阳性、CRP值升高、血管翳强化、滑膜增厚、骨侵蚀、骨髓水肿为指标时对于鉴别早期RA与非RA具有一定诊断价值。

There were significant differences between RA and non-RA groups in morning stiffness, symmetric arthritis, rheumatoid factor positivity, erythrocyte sedimentation rate, C-reactive protein and synovial hyperplasia, enhanced pannus, bone marrow edema as well as bone erosion.

晨僵、对称性关节肿胀、类风湿因子(rheumatoid factor， RF)阳性、血沉(erythrocyte sedimentation rate， ESR)增快、C反应蛋白(C-reactive protein， CRP)值升高诸指标在RA组与非RA组之间具有显著差异性。MRI各主要征象中滑膜增厚、血管翁强化、骨髓水肿、骨侵蚀诸指标RA组与非RA组之间具有显著差异性。

Magnesia alumina spinel brick is based on high-purity magnesia and synthetic magnesia alumina spinel with major crystal phase of periclase and spinel. By intensively mixed, double-face pressed and fired at high temperature. Being completely chrome free, it is the ideal refractory for the transitional zone of cement kiln characterized by superior thermal shock resistance, good anti-erosion capacity, and lower thermal conductivity.
