腔形成

After twelve weeks new bone had converted to lamellar bone, some of which formed bone-shell. Marrow cavity was seen.

第12周，新骨组织形成板层状结构，髓腔明显，内含造血和脂肪细胞，第24周，新骨结构典型。

While in the BMP/HA group, although the fibrous callus was appeared in the 4th and 8th weeks, the HA was not absorbed. In the 12th and 16th weeks the change was similar to that in the 8th week and no recanalization of bone marrow cavity.

而BMP/HA复合组，虽然在第4、8周也有纤维性骨痂形成，但HA不被吸收；第12、16周与第8周相似，无髓腔再通现象。

RESULTS: A total of 36 rabbit models, 6 in the 1-month therapy group and 8 in the 3-month therapy group were died from infection. In the 1-month therapy group, thick ureteric wall and smooth ureteric lumina developed without any contracture. Under the optical microscope, transitional epithelial cells covered throughout the inner walls and smooth muscle cells appeared sparsely in a mussy configuration. In addition, CKAE1/AE3 staining was positive butα-actin staining was very weak when checked by immunohistochemistry. In the 3-month therapy group, amnion-ureters were enclosed by their peripheral tissue and showed rich blood vessels and normal ureteric lumina without significant contracture, futher more, there had formed a well-arranged transitional epithelial layer and smooth muscular layer, the immunohistochemistry result showed that the expression of CKAE1/AE3 and α-actin were positive.

结果：36只大白兔中，1个月治疗组死亡6只，3个月治疗组死亡8只，死亡原因均为感染。1个月治疗组大白兔羊膜输尿管柔软，长4 cm，管壁变厚，无挛缩，移行上皮组织爬满内壁，平滑肌组织部分再生，但较稀疏，排列不规则；免疫组织化学检查提示CKAE1/AE3染色阳性，α-Actin染色微弱。3个月治疗组大白兔羊膜输尿管与周围粘连，有丰富的血运，无明显挛缩，管腔不缩小，已形成良好的移行上皮层和平滑肌层，免疫组织化学显示α-Actin和CKAE1/AE3染色均为阳性。

The results show that the discharge and cooling stages of sparkjet were simulated by computational method. The instance energy input can produce the condition of high pressure and temperature in the actuator, which induce the forming of synthetic jet. With the increment of the input energy, the velocity of the synthetic jet could be increased to the supersonic state. Under the periodic energy input, the distribution of the sparkjet velocity on the nozzle is non-sinusoidal. And the discharge velocity of jet is much larger than the suction velocity of the flow from environment.

计算结果表明：采用本文的计算方法可以模拟出火花型激励器喷射、吸入的工作阶段；电火花瞬间能量的输入产生了腔体内的高温、高压环境，从而诱发合成射流的形成；当激励能量增加，激励器产生的合成射流速度增加，可达到超声速状态；周期性激励下，火花型合成喷喷口处的轴向平均速度随时间不是正弦分布，且喷射过程的最大速度要远远大于吸收过程的最大速度。
