肝细胞癌中缺氧诱导因子-1α、热休克蛋白70的表达】；综上所述，肝细胞癌发生后，由于血供不足诱导HIF-1α过度表达，应激状态下产生的HSP70通过减轻缺血性损伤，增加毛细血管的生成及减轻细胞凋亡等途径使肿瘤细胞的增殖、移行加快，促进恶性肿瘤的生长、浸润和转移，使肿瘤细胞在适应缺氧、能量代谢、细胞凋亡及转移中起重要作用。

The expression of Fstl1 was increased at 3 d and then returned to control levels at 1 wks in cervico-lumbar segment of the spinal cord. However, Fstl1 expression was significantly lower at 3 wks than control values at 2 wks in regenerating blastema.

在断尾损伤模型中，多疣壁虎Fstl1表达呈动态变化，其在近端脊髓组织中，损伤3天时Fstl1转录表达增高，并随后开始下降恢复；在断尾再生尾芽中，3周时 Fstl1转录表达低于2周表达量。

Primers used in PCR were designed based on the sequence of mitochondrial 16S rDNA (AJ250642 and AF312718) and beta-actin (AY910691) of Eriocheir sinensis which had been deposited in GenBank. PCR analysis using total DNA from muscle, branchia, testis and sperm indicated that 16S rDNA exhibited different expression in the four samples. Beta-actin gene was detected plentiful in all the four tissues/cells and exhibited the same expression pattern. 16S rDNA gene amplification was detected at high levels in muscle and branchia, appreciable low in testis and very low in sperm. The PCR products of 16S rDNA gene were sequenced and aligned with the sequence of 16S rDNA from GenBank (AJ250642 and AF3 12718), and the alignment result showed there was no difference between them.

通过GenBank中的中华绒鳌蟹线粒体16S rDNA序列设计引物，利用PCR扩增方法，以beta-actin做内参，检测了中华绒螯蟹肌肉、鳃、精巢和精子中线粒体16S rDNA扩增情况，发现各组织或细胞beta-actin扩增片段大小、条带宽度和亮度基本一致，表明各模板DNA量基本一致；而在同一DNA浓度下，16S rDNA的扩增片段长度虽一致，但其产物量存在明显差异，精子16s rDNA产物量显著低于其他3种组织，其条带宽度和亮度很弱；16S rDNA扩增产物经测序分析及比对证明与已有序列完全吻合。

In his first period works as if you go through a violence and fearful world, that also according to the prevalent style of writing in the pioneer literature age at that time. He abandoned the common sense and building a widely different world from the common sense experience, we take effort to his brimless tribulation in his novels and research into his core of his described topic, to analyze the factor of violence in his works, at the same time affirm this expression, it also describe the nonplus to this expression.

在他的前期小说中仿佛走进了一个暴力和恶的世界，这也是当时先锋文学普遍的文风所向，他背弃了常识，构筑了一个与常识经验迥然不同的世界，我们从余华小说中无边的苦难着手，来探究他所描述的主题的内核，在分析他作品中的"暴力"因素时，在肯定这种表现手法的同时，也表达了对这种手法的困惑。
