裂隙清楚的

This observation has the advantage of bracelets inside the fissures, and cracks will be seen very clearly.

这样观察的好处是手镯里的裂隙、裂纹会看得非常清楚。

On magnification, all tumors have sharp peripheral circumscription and all tumors were confined to the upper dermis,and tumor continuity with the epidermis was noted in some cases.Some basloid aggregations associated with a palisaded alignment of the cells at the periphery of the aggregations can be seen..

镜下可见肿瘤边界清楚，大多位于真皮浅层，部分与表皮相连，可见多数基底样细胞集合，周边细胞核成栅栏样排列，绕以明显的纤维性基质以及纤维母细胞，有时在结缔组织之间可见裂隙。

This characteristic has been shown to be particularly true in limestone areas where cracks and crevices occur.

在有断裂和裂隙的石灰岩区域，这种物性表现得特别清楚。

Results 1、 Generally, we can see the original blue and white, shiny, no cracks in the articular surface of the cartilage after the stress increases gradually yellow, surface roughness, cracks appear; when the pressure decreases, the yellowing, rough, the color of the fracture restore gradually and become shiny.2、the shiny smooth surface can be seen under a light microscope, formation, cell distribution, tidy, clear the level of cartilage at the articular surface stress increases, the surface roughness changes, defects, disordered cells, uneven dyeing ; when the articular surface of the pressure gradually decreased, the cartilage gradually repair and the surface of cells at the surface appear only disorder.3、immunohistochemical observation can be seen throughout the observation period, cartilage cells are type Ⅱ collagen expression and expression after 3 weeks gradually weakening, when the seventh week begin to strong gradually.4、 electron microscopy shows that when stress increases the articular surface, the cartilage cells became flat, the cytoplasm in the endoplasmic reticulum, Golgi apparatus decreased with collagen disorders; and when stress decreases the articular surface, cartilage cells gradually returned normal, cytoplasm in the endoplasmic reticulum, Golgi body gradually restore quantity; collagen fibers with a gradual rules.

结果：①大体观察可见到原本蓝白色、有光泽、无裂纹的软骨在关节面压力增大后，逐渐呈灰黄色，表面粗糙，出现裂隙；当压力逐渐减小后，变黄、粗糙、有裂隙的软骨颜色逐渐恢复，变得有光泽②光镜下可见表面光滑、平整，细胞分布均匀、整齐，层次清楚的软骨在关节面压力增大后，表面变粗糙、缺损，细胞排列紊乱、染色不均；当关节面压力逐渐减小后，软骨表面逐渐修复，细胞仅在表层排列紊乱③免疫组织化学观察可见整个观察期内软骨细胞胞浆内均有Ⅱ型胶原表达，术后3周内表达逐渐变弱，从第7周时开始逐渐变强。④电镜下可见当关节面压力增大后，软骨细胞逐渐变扁，胞质中内质网膜、高尔基体减少，胶原排列紊乱；当关节面压力减小，软骨细胞形态逐渐恢复正常，胞质中内质网膜、高尔基体数量逐渐恢复；胶原纤维排列逐渐有规则。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
