Our findings are as follows: 1. Mice vestibular development initiated early and the process is short. All macula and crista ampullaris were formed at E15, which Myosin VI was expressed in hair cells at this time but not expressed in support cells.

结果发现：1。小鼠前庭的发育较早、过程较短，E15时所有囊斑、壶腹嵴基本形成，所有壶腹嵴、囊斑里均出现MyosinⅥ阳性表达毛细胞，未见支持细胞表达MyosinⅥ。2。

The shape of chloroplast didn't change after seedling was treated by GA〓, but the number of lamllasomes increased, and starch grain enhanced. These changes were accord to that of the rate of photosynthesis. Mitochondria varied greatly, the structure of mitochondria could see vaguely and carinace almost deliquesce after 4days. Enrolucrum emerged until the seventh day after treatment and endomembrance of mitochondria recovered gradually, cristae could be seen. On the other hand, the endomembrance of mitochondria in CK (normal non-bolting) was obvious and the quantity of cristae in the mitochondria was much more than the GA〓 treatment. This showed that respiration might decrease after GA〓 treatment while reduced the depletion of photosynthesis products and enhanced bolting.

GA〓处理后抽苔过程中叶绿体形状未发生变化，但类囊体增多，淀粉粒增多，这种变化与光合速率的变化吻合；线粒体变化较大，处理后4天线粒体结构较模糊，嵴不清晰，7天时外膜形成，内膜也逐渐恢复，能见到嵴，而对照线粒体内膜结构明显，嵴清晰数量也多，说明GA〓处理后，呼吸作用降低，减少光和产物的消耗；细胞膜无破损，较光滑完整，说明对细胞膜没有伤害。

Results Trunk neural crest stem cells were successfully isolated and cultured. The immuocytochemcal result showed that the cells were nestin-and P75-positive. Trunk neural crest stem cells grew through adhering to chitosan fiber after inoculation. Under an electon microscope, the spindle-shaped trunk neural crest stem cells were proliferated and migrated along the fiber. The cells arranged side by side or linked by heads and tails in processes. The ends of S-100 positive cells were flat and expanded, adhering to the fiber as claw-shaped pseudopodium.

The optimal entrance point mostly locate at the root of accessoryprocess which adjacent to the mamillary process from L1 to L4, Theadjustable range of entrance points of the 4 segments almost cover theaccessory process, But at L5, The optimal entrance point is much moreoutside away from the accessory process, just at the middle of thetransverse process and the adjustable range of entrance points islimited.

这与钉尾间距的明显变化相一致，手术时应注意调整螺钉钉尖内偏角度观察椎弓根螺钉进钉点发现内外侧螺钉进钉点与内上、外上螺钉进钉点构成接近矩形的梯形区域，最佳进钉点居于内外进钉点中部。L1到L4最佳进钉点位于副突根部靠近乳突处，随着椎体节段下降，进钉点逐渐移向外侧，L1最佳进钉点基本在副突根部骨嵴内侧缘，L2、L3最佳进钉点基本在副突根部骨嵴上，L4最佳进钉点基本在副突根部骨嵴外侧缘。L1到L4可选进钉点范围几乎均包含副突骨嵴。L5最佳进钉点则明显偏外，多数位于副突根部与横突外端连线的中内1／3。

The result showed that the surface architecture and ultrastructure of I.punctatus ' gill and secondary gill lamellae were similar to those of other teleosts. The surface of gill arches and gill rakers was covered with pavement cells which were characterized by circular microridges, and secreting-holes were found among cells on the surface of gill arches. The base part of gill rakers were bigger in terms of diameter. The pavement cells' surface of gill filaments' middle part was characterized by microridges with fine lateral protuberances on both sides which were either fused or interruped, while the microridges disappeared on the pavement cells' surface on both top and base parts of gill filaments, forming dense granulated protuberances. The height and interlamellar space of secondary gill lamellae in I.punctatus were relatively higher and bigger, respectively.

结果表明，斑点叉尾鮰鳃的表面结构和微细结构与其他硬骨鱼类基本相似，鳃弓和鳃耙表面被具环形微嵴的扁平上皮细胞所覆盖，鳃弓表面细胞之间有孔洞；鳃耙基部较粗壮；中部鳃丝上皮细胞表面的微嵴两侧有细小的横突，有些微嵴出现融合或间断；端部和基部鳃丝上皮细胞表面的微嵴消失，形成密集颗粒状突起；鳃小片的高度和片间距较大。

Careful treatment can decrease the complication rate. 3. Three-dimensional finite element model analysis showed that zygomaticoalveolar crest is the major site sustaining stress, which indicated that the fixation of zygomaticoalveolar crest should be strengthened, if there is some space between zygomaticoalveolar crest and fibula bone, free bone graft can fill the space to rebuild the bony zygomatic process support.

游离腓骨复合组织瓣上颌骨重建的三维有限元分析表明，颧牙槽嵴部位是腓骨瓣上颌骨重建后咀嚼压力的主要受力部位，提示腓骨瓣上颌骨重建时要加强颧牙槽嵴的固定；当上颌骨切除后腓骨与颧牙槽嵴存在间隙时，应尽量采取游离骨块移植，充填间隙，重建骨性颧突支柱。
