This study investigated the mechanisms that induce EMT and the significance of extracellular signal-regulated kinase cascade in this course in vitro.

本文旨在研究酸性成纤维细胞因子对上皮-间质转分化的影响，探讨有丝分裂原激动蛋白激酶的ERK信号传导途径在此过程中的作用，为肾小管-间质纤维化的防治提供理论依据。

The process of EMT is induced in epithelial cells to lose its cell-to-cell adhesion and transform to mesenchymal-like cells.

同时，近端肾小管的纤维母细胞亦经类似 EMT 之机制而转变成纤维原母细胞，此也是造成肾病变的因素。

But in SD rats, cardiac muscle fibers were fractured seriouly , contracted to wavilness obviously, then muscle fibers fracture were contracted like entasia by the hypoxia time increased , injury intensify , all the changes refered SD rats compensatory mechanism can not be transferred in this hypoxia degree. 3. Exposed to 4% oxygen concentration, the cardiac muscle ultrastructure of Gansu zokors had serious injury after hypoxia 2h.

在4%氧浓度的低氧耐受实验中，甘肃鼢鼠在低氧2，4h后，心肌纤维收缩明显呈波浪状，低氧时间延长至6，8和10h后，心肌显微波浪状收缩由强逐渐变弱，并逐渐恢复至正常状态，说明鼢鼠心肌在6h以后对严重缺氧环境开始代偿性适应；SD大鼠2h组心肌纤维断裂严重，收缩加强成明显的波浪状，随着低氧时间得增加，4h组呈严重成挛状收缩，损伤加剧，提示SD大鼠在这一氧浓度下已经无法正常调动其代偿机制。3。
