Methods The clinical data of 42 cases were analysised by retrospective study.15 cases were put double pigtail stents via cystoscope and 3 cases via percutaneous nephrostomy,22 cases were performed one step's percutaneous nephrostomy and 2 cases pyelostomy. Results The patients were followed - up for 3 - 26 months .

回顾性分析42例恶性肿瘤并发输尿管梗阻的临床资料。15例患者成功逆行放置双猪尾导管，22例首选一步法经皮肾穿刺造瘘术，3例实施肾造瘘加顺行双猪尾导管置入术，2例行开发性肾盂造瘘术。

Next, in the scheme for teleportation of an arbitrary multipartite GHZ-class state by one EPR pair, only one EPR pair and 3 classical bits are needed, which greatly lessens the oppressiveness of both quantum and classical channels. Then, in the scheme for deterministic, unilateral and controlled teleportation via cavity QED, Alice can determinately send her state to anyone of her agents, whereas the agents can not, with the channel being noiseless. What the agents can do is just to control the teleporting process, which enhance the security of the communication.Besides,based on the schemes discussed above,it is easy to see the character of an entangled state which can accomplish deterministic teleportation via cavity QED.

利用一个EPR对实现n-体类-GHZ态的量子隐形传态方案，整个通讯过程只需要一个EPR对和3 cbits的经典信息，大大节省了物理资源，缓解信道压力；利用非对称类-W态实现确定的单向受控量子隐形传态，在没有噪声的条件下，Alice可以将量子信息准确无误地发送给任一个客户，但每一个客户只能控制配合整个信息的传输过程，客户之间不能实现确定的信息传递，这样便保证了信息的安全性。

You'll also be able to tag photos with keywords and browse them using the tag cloud, geotag images with the location data of where they were shot, share online via Ovi Share or Flickr, or store for mobile viewing on the N900's 32 GB internal memory--which can also be expanded via optional microSD memory cards.

您还可以标记照片的关键字，浏览他们使用标签云，地理标记的图像与数据的位置，他们被枪杀，在线通过 Ovi全分享分享或Flickr，或储存移动看对 N900的32 GB内部记忆-这也可以通过可选的microSD扩展存储卡。

Methods 4-Hydroxybenzonitrile (2) as the starting material was transformed to 4-hydroxy-thiobenzamide (3) via thioformylation. And ethyl 2-(4-hydroxyphenyl)-4-methylthiazole-5-carboxylate (4), which was synthesized via cyclization from 3, was treated with hexamethylenetetramine to generate the intermediate ethyl 2-(3-formyl-4-hydroxyphenyl)-4-methylthiazole-5-carboxylate (5). The target compound febuxostat (1) was obtained from 5 by etherification, cyanidation, hydrolysis.

以羟基苯腈为原料，经硫代甲酰化得到对羟基硫代苯甲酰胺(3)，3经环合得到2-（4-羟基苯基）－4-甲基－噻唑－5-羧酸乙酯(4)，4与乌洛托品反应，得到中间体2-（3-甲酰基－4-羟基苯基）－4-甲基－噻唑－5-羧酸乙酯(5)，之后再经醚化、氰化、水解得到目标产物(1)。

Objective: To study the influence of total hysterectomy via abdomen or via vagina on immune function of patients.
