Neural Regeneration Research 2011年第35期6卷 2768-2772页

作者： Xiaojing Xu Min Wang Jing Liu Jingya lv yanan Hu Huanxiang Zhang Department of Cell Biology Medical College of Soochow University Jiangsu Provincial Key Laboratory of Stem Cell Research Suzhou 215123 Jiangsu Province China

As supportive cells for neuronal growth and development, much effort has been devoted to the role of astrocytes in the normal state. However, the effect of the astrocytes after injury remains elusive. In the present study, neurons isolated from the subventricular zone of injured neonatal rat brains were co-cultured with astrocytes. After 6 days, these astrocytes showed a mature neuron-like appearance and the number of surviving neurons, primary dendrites and total branches was significantly higher than those at 3 days. The neurons began to shrink at 9 days after co-culture with shorter and thinner processes and the number of primary dendrites and total branches was significantly reduced. These experimental findings indicate that astrocytes in the injured brain promote the development of neurons in the early stages of co-culture while these cells reversely inhibit neuronal growth and development at the later states.

通过开展环氧树脂修复混凝土梁的三点弯曲断裂试验,对比研究了混凝土修复前后的断裂性能,分析了粗骨料含量对双K断裂韧度和断裂能的影响。结果表明:环氧树脂修复可大幅提升试件的最大承载力,且临界裂缝口张开位移几乎不受影响。修复后混凝土的断裂性能可得到有效恢复和提升。其中,粗骨料含量为0(砂浆)、18%、36%和54%时,起裂韧度分别提高56.5%、28.2%、21.5%和21.1%;失稳韧度分别提高13.1%、6.0%、5.5%和8.2%;断裂能分别提高41.3%、39.1%、38.1%和23.2%。修复前后混凝土断裂参数均随粗骨料含量增加而增大,且增幅逐渐变缓。

为了明晰金属碳化物沉淀在铁合金中的形成机理,解决宏观试验无法直接研究碳化物沉淀形成初期的局限性,以碳化钛为研究对象,采用分子动力学模拟方法,研究了碳化钛纳米颗粒形成过程中,碳原子和钛原子的扩散行为,考察了碳化钛颗粒形成过程中温度和碳原子浓度对原子扩散的影响规律。研究结果表明,原子的扩散行为对碳化钛颗粒形成起到关键作用。扩散过程中,扩散系数较低的钛原子对碳化钛的形成起决定作用。钛原子和碳原子的扩散能力随温度的提高而增加,但随碳原子浓度的增加而降低。
