The first passage of YS-MSCs which grew in good condition was obtained, and adipogenic differentiation of YS-MSCs was induced by dexamethasone and insulin, and angioblast was induced by vascular endothelial growth factor and basic fibroblast growth factor.

取生长状态良好的第1代细胞，以地塞米松、胰岛素定向诱导卵黄囊间充质干细胞向脂肪细胞方向分化；以血管内皮生长因子和碱性成纤维细胞生长因子体外诱导其向血管内皮细胞方向分化。

Methods forty patients with head/neck 16 slice CT angiograph were divided into two groups at random,each group has 20 cases, the plain scan and the CTP was performed before CTA to all 40 cases. Group A use CTP to obtain the peak time of contrasted artery as CTA delay time, and scan from head side to foot side. Group B use contrast media automatic bolus tracking to obtain delay time,scan from foot side to head side.two groups CTA images were collated.

使用16排螺旋CT对40例患者行头颈部CTA检查，随机分为两组，各20例，所有患者在CTA之前行脑CT平扫及脑CT灌注扫描，A组以CTP所显示的动脉峰值时间作为CTA的延迟时间，扫描方向为自头侧向足侧。B组使用造影剂浓度实时监控跟踪触发技术确定延迟时间，扫描方向自足侧向头侧扫描，两组CTA图像相对照。

Typically, in one direction, the pathway is oxidative, dissimilatory, and produces adenosine 5'-triphosphate, and in the opposite direction, the pathway is reductive, assimilatory, and energy consuming.

经典的循环可以概括为，在一个方向上是氧化，异化，产生三磷酸腺苷即能量，在另一个方向还原，同化，消耗能量。

Tension moves asymptotically toward the direction of the ''.

最大张力的方向是逐渐趋进于切线的方向。

Using stereomicroscope, we observed the fracture line direction and location as well as the angle between the fracture line and the attrite plane. The data was compiled into statistics and analyzed. The results revealed that most of the vertical root fractures occurred in teeth with severe attrite crown and flat root. Numerous bucco-lingual oriented fractures occurred in the mesial root of molars, and we found three non-endodontically treated cases with mesio-distal oriented fractures in the palatal roots.

结果发现，两组的垂直牙根断裂均好发於牙冠严重磨耗（77.4-88.2%）且扁平的牙根（61.8-75.8%）上，以大臼齿的近心牙根发生率最高（64-85.7%），多为颊舌侧走向（91.2-91.9%），且於未根管治疗组别亦发现三例腭侧根断裂，走向为较宽的近远心方向，显示牙根断裂会沿著牙根较宽的方向发生；同时，未经根管治疗而产生垂直牙根断裂的牙齿具有根叉位置较低的现象（61.8%），牙根於比例上有较短小的特徵。

The azimuthally linear advection may results in that the meso-scale vortex of initially circular shape becomes the elongated and spiral vorticity bands; the radial linear advection may transfer the vorticity of the outer region towards the center of the typhoon.

沿e方向的线性平流可使初始圆形的中尺度涡旋演变为狭长的螺旋状的涡量带；沿径向线性平流的引进可使外区涡量向台风中心方向传播。

This paper utilizes varied methods to determine the modern times direction of maximum principal stress in Baka oilfield, and makes use of hydraulic fracturing data to estimate size and distribution law for three direction principal stress, in order to try hard to reflect objectively and authentically in-situ stress conditions at present for Baka oilfield.

文章运用多种方法确定了巴喀油田现代最大主应力的方向，利用水力压裂资料估算了3个方向主应力的大小及分布规律，力图客观真实地反映出巴喀油田现今地应力的状况，并简单阐述了裂缝与古今地应力的关系及在不同开发时期的作用。
