Results The main CT features of adrenal neuroblastoma in children included:huge and irregular mass(25 cases),the density is more even(18 cases),calcific

结果：儿童肾上腺神经母细胞瘤的CT主要表现有大的不规则肿块25例，密度较均匀18例，钙化12例，囊变或坏死8例，出血4例，越过中线22例，包绕腹膜后大血管20例，腹膜后淋巴结肿大18例，2例肝转移，8例腹腔积液，2例盆腔转移。

Methods The Wistar rats were used as the experimental animal. On the back of each rat, a skin flap, measuring 1.5 cm×6 cm, caudally based, was elevated. Wound edges and the flap bed were separated from the flap itself by a silicone sheet. The VitC, bFGF, Magnesium sulfate and Papaverine were taken in the areas between flap and sheet. With 8 rats in each group, the drug-taken group was as trial group, while the physiological saline group was as control group. On the seventh day after the flap elevation, flap survival length was measured.

以鼠背部中线为中轴，以两侧髂嵴连线为蒂，形成一个1.5cm×6cm的单蒂皮瓣，其全长自皮肌层下与深筋膜游离，下垫置医用硅膜，硅膜以不露出切口，又起到阻隔真皮血运为宜，以小三角针用3-0丝线先缝合皮瓣两侧切口，然后将上述4种药物加入皮瓣与硅膜之间，再缝合皮瓣的头端将维生素C、bFGF、硫酸镁、罂粟碱分别作为实验组，以生理盐水作为空白对照组，每组8只动物，术后单笼喂养7d，取材并检测皮瓣存活的长度。

Results: The origin of inferior mesenteric artery was successfully localized by dissection in Toldt's space cephalad to the aortic branch after the middle Toldt's line incision.

结果：切开中线侧Toldt's线，在主动脉分杈头侧的Toldt's间隙内可顺利定位肠系膜下动脉(inferior mesenteric artery， IMA)起点。

We report an exceptional case of a NMC presenting outside of midline structures in the parotid gland and showing mesenchymal chondroid differentiation in a 15-year-old male.

在此，我们报道一例特殊的NMC，患者15岁，男性，肿瘤不位于中线结构，而发生在腮腺，并显示软骨样间叶组织分化。

Results:Most of the intracranial chordoma（16 cases in our group,88 9%）were located in the middle area of the skull base such as clivus and/or sellar region and always invaded extensively the nerves and major in tracranial vessels of skull base.All tumors were hypointense on T1- weighted imaging and heterogeneous hyperintense on T2- weighted imaging,On Gd- DTPA contrast- enhanced T1- weighted imaging 8 chordomas enhanced more markedly,but steady heterogeneous.

结果：颅内脊索瘤大部分（本组16例，占889%）发生于颅底中线处的斜坡和/或鞍区，并广泛侵犯颅底的神经和大血管等重要结构；在T1加权像上肿瘤主要表现为低信号，T2加权像上表现为不均匀高信号，Gd-DTPA静脉注射增强后（8例）均出现较明显的不均匀强化。

The median part of the middle fossa, the lateral part of the superior clivus and the trigeminal nerve in the Meckel cave could be exposed via a retrosigmoid suprameatal approach.

采用乙状窦后经内耳道上入路，可将乙状窦后入路的手术野扩大到颅中窝的中线侧和上斜坡侧方，并可显露Meckel腔内的三叉神经。

The screw entry point was located at the tip of transverse process. The average inclination angle should be 10°-20° headward and 30°-40° toward neutral line respectively. The screw was inserted and entered into the vertebral body along the external cortex of pedicle. The integrity of cortical bone around screws, the distance to segmental blood vessels and the penetration of cortex were observed after operation to evaluate the accuracy and safety of screw placement. Among 160 thoracic pedicle screws that were implanted in 34 cases, 148 screws (92.5%) were accurately inserted inside the costotransverse unit, and 12 screws (7.5%) were misplaced according to the image of X-ray and CT thin-slice scan.

应用椎弓根外内固定技术2004/2007年在中山大学附属第三医院骨科治疗34例患者，固定前采用CT加密扫描测量进钉点、进钉点至椎体前缘的深度、进钉角度和直径，固定中椎弓根钉入点为横突尖，进钉方向为平均向头侧倾斜10°~ 20°、与中线成角30°~40°，顺椎弓根外侧皮质进入椎体，固定后CT加密扫描观察螺钉周围的皮质骨是否完整、是否靠近节段血管、是否穿透皮质骨，评价置入钉的准确性和安全性。34例患者共置入160枚胸椎椎弓根螺钉，固定后CT加密扫描和X射线片观察到148枚(92.5%)螺钉置入准确，12枚(7.5%)螺钉发生错置。

A bright, round or oval glow in the midline just below the cricothyroid junction could be a reliable pattern to indicate the ETT-TL tip has passed the vocal cords.

在正中线、环状软骨甲状软骨交界处的下方的明亮、圆形或椭圆形的亮光，可视为气管内管/ TrachlightTM 组装单位的尖端已经通过声门的可靠形态。

When the ETT-TL tip was placed inside the glottic opening, a brightest; round or oval glow could be consistently seen in the midline just below the cricothyroid junction in each cadaver.

当气管内管/ TrachlightTM 组装单位的尖端放置入声门，每一个大体老师都可见光度最大、圆形或椭圆形的亮光，而位置就正好在正中线、环状软骨甲状软骨交界处的下方。

One view, that episodic memory and semantic memory are both dependent on the integrity of medial temporal lobe and midline diencephalic structures, predicts that amnesic patients with medial temporal lobe/diencephalic damage should be proportionately impaired in both episodic and semantic memory.

一种观点认为，情节记忆和语义记忆都依赖颞叶内部和间脑中线结构，预言颞叶内部、间脑损伤的健忘症病人的情节和语义记忆会相应比例地被削弱。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
