Summary of Background Data. Pedicle or anterior screw fixation is commonly used with interbody deice fixation.

在48块胸腰椎椎体中，选用椭圆形或者四叶状的锯齿边缘的压力器，接触椎体的面积约为40％的终板面积，作轴向压迫。

Methods. An elliptical or a cloverleaf-shaped indentor covering 40% of the endplate was axially compressed against the superior endplate of 48 thoracolumbar vertebrae.

ResultsMorphological features with diagnostic value were established as follows:①Irregular or round-mesh basket type nucleolus;②Malformed nucleus and lobate nucleus with fine bridge;③Perinuclear microfilaments;④Nuclear bodies;⑤Nuclear inclusion bodies;⑥Marked cell pleomorphism arranged irregularly,like a disordered stone pavement;⑦Strange cell and/or giant cancer cell were found;⑧Peculiar papillae or cell clusters were formed;⑨Specific function structure on the surface of cell differentiated poorly.

结果 确定了具有诊断意义的形态学特征：①不规则奇形核仁或网孔状核仁；②畸形核，分叶核伴细桥－核间桥形成；③核旁微丝；④核体；⑤核包涵体；⑥细胞重度多形性，排列紊乱，似乱石铺堆；⑦出现奇形细胞和/或癌巨细胞；⑧形成奇形乳头和奇形细胞簇；⑨细胞表面特异功能结构分化不良。

In the Filicinophyta, Sphenophyta, and Lyophyta the embryo sporophyte produces a footlike structure that remains embedded in the tissues of the parent gametophyte plant, absorbing nutrients like the suspensor of higher plants.

在真蕨门 filicinophyta ，楔叶门 sphenophyta，和石松门 lycophyta 中，胚胎孢子体产生足状结构，仍然包裹于双亲配子体植物内。胚胎吸收营养的方式同高等植物从胚柄那样吸收营养一样。

There were no statistically differences between the 8th~ 14thday, the 15th - 21th day post-BC and the control group. During the rt~24tkday post-BC , pycnosis degeneration or necrosis neurons of the locus cerebral cortex, dorsal hippocampus, dentate fornix were significantly increased, then decreased gradually, but recovered to normal by the 24thday after BC, and especially in parietal cortex and piriform cortex the necrosis neurons were significantly increased than temporal cortex , and there were no statistically difference berween the left and the right side. Pycnosis degeneration or necrosis neurons in the brainstem reticular formation were markedly increased in the 4thday after BC, and there were no statistically difference among the other groups and the control group.

与对照组相比，BC后在大脑皮质、背侧海马和齿状回部位，固缩变性和不完全坏死细胞数先显著增加(P＜0.05)，然后逐渐减少，至24d基本恢复正常；顶叶、梨状皮质比颞叶皮质变性坏死细胞多，差异有高度显著性(P＜0.01)；大脑左侧比右侧变性坏死细胞稍少但差异无显著性；在BC后4d，脑桥核、斜方体核平面的脑干网状结构中固缩变性和不完全坏死细胞数明显增多(P＜0.05)，其它组间无显著性差异。

Intermediate between these is the solenostele in which the leaf gaps are more widely spaced vertically so that only one is seen per cross section of the stem.

这两者的过渡体是管状中柱，由于叶隙在垂直方向上广泛分布，所以每个横截面上基本只能见到一个叶隙。

Cauline leaves petiolate or sessile and cuneate or auriculate, pinnately or palmately veined, entire, dentate, or crenate; ultimate veins ending or not with apiculate callosities.

具叶柄或者无柄和楔形的茎生叶或者耳形，成羽状或者掌状脉，整个，有齿，或具圆齿；末级的脉以具细尖的胼胝体结束不的或。

Results of the experimental groups: Comparison with the control groups, in 6h and 8h groups eminences of ependymal cells with cobblestone-like appearance were seen, their microvilli were further richer, and a number of microholes could be found on their base. In body part of SFO cell membrane of some ependymal cells were broken completely, their cytoplasm was no longer seen, and cell nucleus located at one side of the cell, 5-7μm in diameter and dividing lobe-like in shape. Beside those cells some ependymal cells appeared many folds on the top of surface. In 2h and 16h groups the observation results seemed no significant differences from the corresponding control groups.

实验组结果：与对照组相比，在6小时和8小时实验组中，可见成团的鹅卵石状室管细胞隆起于表面，微绒毛更为丰富，微绒毛根部可见到若干微细小孔，在SFO体部的一些室管膜细胞的胞膜完全破裂，胞质几乎荡然无存，仅剩胞核居于细胞的一侧，直径有5.7μm，呈分裂叶状；与这些细胞邻近的室管膜细胞表面最高处多呈现皱襞。2小时与16小时的实验组的观察结果与对照组相比未发现明显差异。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
