The major advantage of CTA is simple,rapid,noninvasive and reliable.It is very useful for evaluation of cerebrovascular diseases,intracranial hypervascular tumours and skull base tumours,especially sensitive in detection of intracranial aneurysms.

CTA具有简单、快速、无创和可靠等优点，适合于脑血管病、血供丰富的颅内肿瘤及颅底肿瘤的术前诊断和评估，对颅内动脉瘤的诊断具有极高的准确性。

Only the front waist of the abdominal cavity and soft iliopsoas, only in the vicinity of some of the muscles, ligaments and fascia, and other non-bony structures of protection, or lack of coordination in the weight-bearing exercise, vulnerable to injury.

腰部前方只有松软的腹腔和髂腰肌，附近仅有一些肌肉、筋膜和韧带等无骨性结构的保护，因此在负重或不协调的运动中，极易受到损伤。

Leaves opposite , very rarely stipulate, petiolate, entire, leathery to papery, usually glabrous; secondary veins usually prominent, numerous to few, oblique to perpendicular to midvein; tertiary veins reticulate, with adaxial brownish transvenous resin canals and abaxial linear or intervenous translucent glands; petiole often with basal liguliform appendage.

叶对生 ，极少具托叶，具叶柄，全缘，革质到纸质，通常无毛；次脉通常突出，许多对很少，偏斜到与中脉垂直；第三脉网状，具正面带褐色的transvenous树脂道并且背面线形或脉间的半透明的腺体；叶柄通常具基生舌状的附属物。

Filaments connate at least to middle; fruit capsular dehiscing loculicidally by 5 valves; seeds winged at both ends

花无梗 花瓣缺乏以极小的基础状态存在的或；子房差不多上位；花的杯状瓶形，在嘴的明显狭窄和隐藏子房；果不具皮孔。

The meizoseismal area was oval in shape along NW direction with its major axis along the strike of the regional tectonic structure.

这次地震发生在人烟稀少的高山地区，震中周围120km范围内无居民点，极震区内的天文站及边防哨卡的房屋有不同程度的损坏。

Dense alloy coating without pore and inclusion is obtained which metallurgically bonded with steel but existing a few cracks. The results show that the cladding alloy coating is mainly composed of single-phase Fe3Al, and the microstructure is coarse equiaxed grain-groups that consist of large amount of fined slug like Fe3Al grains, between which some adjacent grains have the similar orientation.

试验获得了致密、无肉眼可见气孔、夹杂的合金层，合金层与基体间完全冶金结合，但存在裂纹现象；熔覆合金层主要由单相Fe3Al构成，覆层组织为粗大等轴状晶团，等轴状晶团由大量极细小的条状Fe3Al晶粒构成，一些相邻的条状晶粒之间具有基本一致的晶体学取向。

In order to clarify the genetic mechanism of the adhesion,an in vitro adhesion experiment was carried out for three variants of E.coli F4in 366 piglets of three pig breeds.The results showed that there existed significant differences(P.001)in the adhesion percentage among the three breeds.Most SB piglets were nonadhesive for all the three variants,whereas most LR piglets were adhesive.Within each breed except for LR,the proportions of the three F4 variants adhering to the brush borders differed significantly.

为了研究黏附的遗传机制，本实验利用大白、长白、松辽黑猪的小肠刷状缘细胞与F4ab、F4ac、F4ad进行离体黏附实验，结果发现3品种猪之间黏附情况存在显著差别(P《0.01)，松辽黑猪以非黏附型为主，而长白猪中黏附型比例较高，在同一品种猪内，3种菌株的黏附比例在松辽黑猪内和大白猪内有极显著差异，但在长白猪中无显著差异。

Jensen's group randomized 32 high-risk patients with severe ulcer hemorrhage and nonbleeding adherent clots resistant to target irrigation to medical therapy or to combination endoscopic therapy, which included epinephrine injection, shaving down the clot with cold guillotining, and bipolar coagulation on the underlying stigmata.

受试者包括32名严重溃疡出血的患者，目标灌洗对溃疡面上的无出血粘著血凝块无效，他们的再出血危险率很高。Jensen小组将这些患者进行了随机分组，其中一组接受药物治疗，另一组联合内视镜治疗。联合内视镜治疗包括注射肾上腺素，用冷切刀削去血凝块，以及将双极凝结剂涂抹于潜在出血处。

Results: The results showed that NOS positive neurons existed in all the auditory afferent nucleus while NOS negative neu-rons existed in the superior olivary nucleus. Most of NOS positive neurons in CNC were located in the posterior ventral cochlear nu-cleus ,which were round or oval bipolar neurons. NOS positive neurons were also found in potine widely.

结果：在脑桥的各级听觉传入核团，均有NOS阳性神经元，而上橄榄复合体无NOS阳性神经元；耳蜗核内NOS阳性神经元，主要集中在后腹侧核，为圆形或椭圆型双极神经元；下丘的臂内侧核NOS阳性神经元呈小的、圆形细胞。
