Materials and Methods:16 patients were treated with intra-arterial thrombolysis using urokinase (median dose,60×104 IU).

材料与方法：对 16例发病在 2～ 8h内的急性缺血性脑梗死患者进行颈动脉内溶栓治疗。

Cell culture cytotoxic test, skin allergy test, intracutaneous stimulation test, primary skin stimulation test, hemolysis test , general acute toxicity test and pyrogenicity test were performed according to the manual of the national standards of medical materials.

方法带瓣牛颈静脉经单宁酸处理后按国家医用材料的要求进行浸提液的制备、细胞毒性试验、过敏试验、皮内刺激试验、原发性皮肤刺激试验、溶血试验、急性全身毒性试验及热原试验等生物学评价试验。

METHODS AND RESULTS: Adherent platelets express substantial amounts of SDF-1 and recruit CD34+ cells in vitro and in vivo. A monoclonal antibody to SDF-1 or to its counterreceptor, CXCR4, inhibits stem cell adhesion on adherent platelets under high arterial shear in vitro and after carotid ligation in mice, as determined by intravital fluorescence microscopy.

方法和结果：在体和离体的粘附血小板表达大量SDF-1、募集CD34+细胞，在体荧光镜下可见，在小鼠颈动脉结扎后、离体条件下的动脉内高剪切应力时，SDF-1或其相应受体的单克隆抗体－CXCR4抑制干细胞粘附于血小板上。

A monoclonal antibody to SDF-1 or to its counter receptor, CXCR4, inhibits stem cell adhesion on adherent platelets under high arterial shear in vitro and after carotid ligation in mice, as determined by intravital fluorescence microscopy.

采用活体荧光显微镜，对颈动脉结扎后小鼠和体外的高剪切力动脉进行研究，结果发现SDF-1的单克隆抗体或其反受体CXCR4，抑制干细胞黏附在相互黏附的血小板上。

He had improvised an intrenchment out of the table; and the man, who but an instant previously, had borne merely the appearance of a kindly old man, had suddenly become a sort of athlete, and placed his robust fist on the back of his chair, with a formidable and surprising gesture.

他好象已意识到自己的处境，切实注意着那屋子里在他四周的一切，他的头在颈子上慢慢转动，以谨慎惊讶的神情，注视着那些围绕他的每一个脑袋，但是绝没有一点畏怯的样子。

Objective: To establish reference criteria of normal angle at the cranial base and the cranio-cervical junctionon MRI and to create a new method for diagnosis of basilar invagination by MRI.

目的：建立颅底及颅颈交界夹角的MRI正常参考标准并提出MRI诊断颅底陷入症的新方法。

MRI not only can be multi-dimensional and muiti-parameter display abnormal bone structure, accurate measurement of basilar invagination,but also clearly shows Chiari deformity and syringomyelia and other diseases, MRIis the most accurate and reliable imaging diagnostic methods.

MRI可多方位多参数显示骨结构畸形，准确测量颅底凹陷，还能清楚显示Chairi畸形及脊髓空洞症等病变，MRI是诊断颅颈交界部畸形最准确、可靠的影像学诊断方法。

Results With the new procedure, the tip of the prostate was peeled off completely without extra treatment, and this piece of the urethra,which was composed of surgical envelope, formed a vase-shaped natural surface to avoid urine irretention. The resected plane was covered by fibre and epithelium of surgical envelope,which could reduce irritation of urethra and bladder, and shorten hematuria and repair time. After enucleation of the enlarged prostate, the borderline became clear and blood supply was reduced, which facilitated the rapid resection without injury.

结果 采用新的切割方法前列腺尖部被完整剜除，无需修整，尖部尿道成为由外科包膜构成的喇叭口状自然界面，经过剜除的增生腺体，界面清楚，血供减少，利于快速切除，不易出现包膜损伤，切除效率明显提高。1000例手术顺利，术后发生短期尿道刺激症者150例，发生膀胱颈挛缩6例，尿道狭窄10例。

Ham was the author of a prophecy cited by Isidore, the son of Basilides Clemens Alexandrinus,"Stromata," vi.

I f one were only an Indian, instantly alert, and on a racing horse, leaning against the wind, kept on quivering jerkily over the quivering ground, until one shed one's spurs, for there needed no spurs, threw away the reins, for there needed no reins, and hardly saw that the land before one was smoothly shorn heath when horse's neck and head would already be gone.

如果我是个印第安人，那就时刻警惕着，骑一匹全速疾走的奔马，御风而行，在颤栗的大地上不断颠簸颤动，直跑得马刺也踢掉了，因为无需用马刺了，缰绳也扔掉了，因为无需缰绳了，而且看不见眼前的大地是一片刈得光光的荒原了，当此时也，马儿的颈子和脑袋都已经没有了。

Finally, according to market conditions and market products this article paper analyzes the trends in the development of camera technology, and designs a color night vision camera.

最后根据市场情况和市面上产品的情况分析了摄像机技术的发展趋势，并设计了一款彩色夜视摄像机。

Only person height weeds and the fierce looks stone idles were there.

只有半人深的荒草和龇牙咧嘴的神像。
