Recently, it is found that the neuron apoptosis caused by brain ischemia is associated with signal pathway of endoplasmic reticulum stress, which is different from the traditional apoptotic pathway. Caspase-12 has been identified as a molecule which initiates apoptosis selectively in response to ER stress and is not activated by other pathways. Caspase-12 is localized on the ER membrane, but once specifically activated by ER stress, it translocates to the cytoplasm.

最近的研究发现，这种细胞凋亡与内质网应激(endoplasmic reticulum stress ER stress)有关，其是一种不同于经典的凋亡途径的新途径，分子伴侣葡萄糖调节蛋白78(glucose regulated protein， GRP78/Bip)表达增高是反应ER stress的最敏感的指标，胱冬酶-12(caspase-12)为鼠源性的内质网膜上的蛋白，它的特点是只被内质网诱导的凋亡所激活而不被其它非内质网因素所激活。

The data from stress box indicate that the observed values usually are smaller than the theoretical ones, and the relationship between the vertical or lateral stress and the fill soil thickness can be described in a power function curve: a- a hb. The fact that the soil stress is bigger in the portion adjacent to the central part of gully and becomes smaller in the portion close to the side illustrates that the gully has an apparent unburdening effect. From the monitoring results of the settlement deformation during and after constructingperiod, the study conducts statistical system analysis and evaluation on the change of settlement with time.

根据压力盒测试结果表明，测量值往往比实际的理论计算值小，填土的竖向和侧向土压力与填土厚度可以用幂次型曲线表示：σ=ah~b愈向沟谷中心部位，土压力值愈小，愈向沟谷边缘，土压力数值越大，说明沟谷边坡具有明显的卸荷作用；根据施工期和工后期的沉降变形监测数据，对路堤内各测点的竖向沉降随时间的变化规律进行了数理统计系统分析和总结，工后期路面沉降和时间关系可用对数曲线表示：S=aln+b，并根据此沉降规律对高填方加筋土路堤的工后沉降进行了预测。

The stress and stability analysis of arch dam and abutment are the main task of traditional arch dam design. Nowadays there are two kinds of analysis method to use. One method is the arch-cantilever load-distribution method, in which the arch dam stress and abutment thrust are calculated, while the stability of abutment is evaluated by rigid body method or other method. The other is FEM method, which evaluates the arch dam stress and stability of abutment at the same time.
