作者：戚蓝陈启振蔡建成 State Key Laboratory of Hydraulic Engineering Simulation and Safety Tianjin University Management Bureau of Panjiakou Reservoir

In order to study the effect of seismic permanent deformation on the safety and stability of earth-rock dam, the permanent deformation is considered as the non-design permanent load, and the stress-strain hysteresis curve is also considered when the earth is under cyclic load. The research work can make the calculation results of plastic collapse more accurate by including the effect of the post-earthquake degree of plastic deformation on the stability of the earth-rock dam, and the dam safety factor decreases from 2.50 to 1.90 after the magnitude-8 earthquake. Moreover, the research work will also improve the design of the earth-rock dam under abnormal operating conditions.

关键词： earthquake permanent deformation earth-rock dam safety factor sensitivity analysis

OBJECTIVE: To investigate the role of tongue coating fluid protein in regulation of congestive heart failure(CHF) in qi-deficiency-blood-stasis ***: We studied patients with CHF(3 patients with qi-deficiency-blood-stasis syndrome and 3 without qi-deficiency-blood-stasis syndrome) to investigate differentially expressed proteins. We also included a control group. A biotin label-based antibody array was used for testing tongue coating fluid samples from patients. Net-work analysis of these differentially expressed proteins was conducted using the STRING database,which can predict the relations between differentially expressed proteins and CHF with qi-deficiency-blood-stasis ***: A total of seven differentially expressed proteins were identified, and among these, transforming growth factor β1(TGF-β1) gets a particular attention for us has drawn specific *** analysis showed a homologous relationship of TGF-β1 with bone morphogenetic protein15, which is associated with myocardial ***: Occurrence and development of CHF may result from certain DE-proteins and associated signaling pathways. TGF-β1 protein may be a candidate marker for assessing the risk of CHF in qideficiency-blood-stasis syndrome.
