6 cases of urethostenosis, 2 cases of urotithiasis and 1 case of urethral valves were cured one time. They were followed up from 10 months to 6 years and no dysuria occurred. 2 cases of external plank shedding after ureteropelvioplasty were treated with a placement of internal plank through the renal fistulization. The placement and evulsion of internal plank were carried out one time in 8 cases of ureteric calculi (the length of one calculi was as long as 4cm) and 12 cases of ureteropalsty. In 5 cases of upper remotion of internal plank, 4 cases were pulled out successfully and one failed to draw out. The effect is satisfactory to treat urological diseases by means of ureteroscopy in children.

结果 6例尿道狭窄、2例尿道结石、1例尿道瓣膜均一次性治愈，随访10个月~6年，无排尿异常。2例肾盂输尿管成形术后外支架管脱落经肾造瘘口放置内支架；8例输尿管结石（1例石街长约4cm）、12例输尿管成形术后内支架置入和／或拔出均一次完成。5例内支架上移中4例顺利拔出，1例失败、结论输尿管镜对小儿尿路系统大部分疾病的处理有满意效果。

完成491例腹腔镜胆总管切开纤维胆道镜取石，&T&管引流术（laparoscopic choledocholithotomy Ttube drainage，LCTD），出现胆漏11例，经保守治疗治愈。173例经过胆囊管取出胆总管结石，无并发症发生。

Methods From March 1992 to January 2005, there were 395 cases undergoing LCDET, involving choledochotomy, electrohydralic lithothipsy, dilation stenosis, stent placement and T-tube drainage.

从1992年3月～2005年1月，运用腹腔镜胆总管探查T管引流术的手术方式，包括胆总管切开，胆管镜取石，液电碎石，扩张狭窄，放置支架，T管引流，对395例病人进行治疗。

Conventional CT showed 44 cases of edematous type, dynamic contrast enhanced CT found 28 cases had different degree of necrosis of the pancreatic tissue, 6 cases were found to have focal hemorrhage, peripancreatic fluid accumulation were found in 32 cases, pseudocyst were found in 3 cases, abscess in 2 cases.

常规平扫显示胰腺水肿44例，动态增强扫描显示28例出现不同程度的胰腺组织坏死，6例检出局灶性出血；胰周液体聚集32例；假性囊肿3例，脓肿2例；伴胆石症15例，胆囊肿大或胆囊壁增厚22例；胆急管扩张12例，胰管扩张5例；胸腔积液11例。

Methods: The twenty one cases by retroperitoneal laparoscopic ureterolithotomy and 20 cases by open ureterolithotomy were reviewed retrospectively.

回顾性分析21例后腹腔镜输尿管切开取石术和20例开放性输尿管切开取石术患者的临床资料，比较两组手术时间、手术并发症、术后肠功能恢复时间、术后使用抗生素时间、术后拔除引流管时间、术后拔除导尿管时间、术后住院时间、总住院费。

Look at the history of Chinese jewelry and cultural development, as early as the mid-Palaeolithic our ancestors on the use of animal teeth, shell, bone tubes, ostrich eggshell, stone beads and other ornaments to create strings, till ten thousand years before the turn of the new Paleolithic period, and further selection quartz, jasper, agate, obsidian and other semi-transparent colored material to create a variety of decorations, to the Xia Shang Zhou period, the Chinese men's and women's jewelry category was already very rich, and headgear are hairpin, comb, crown; ear decorated with rings; Necklace necklaces; hand-decorated with bracelets, Yuan and so on.

看看中国珠宝和文化发展的历史，早在中期旧石器时代我们对动物牙齿，贝壳，骨管，鸵鸟蛋壳，石珠等装饰品使用的祖先创造的字符串，直到万年前翻开新的旧石器时代，并进一步选择石英，碧玉，玛瑙，黑曜石等半透明彩色材料创建各种装饰，到夏商周时期，中国男子和女子的珠宝类产品已经非常丰富，帽的发夹，梳子，冠；耳装饰戒指，项链项链，手与手镯，元等装饰。

Methods: Electrohydraulic lithotripsy through the T tube treated 142 cases who had choledoochoscope with T tube drainage.

142例行胆总管探查和T管引流术后经T管行液电碎石及取石治疗。

Melting point 3410 ℃, boiling point 560 ℃, relative density of 1935, F the external electronic structure of 5d46s2, in the chemical reaction time is very easy to lose 1-6 electronic, but also can get 1-2 electronic, so oxidation number of 0,± 1,± 2, 3, 4 , 5 and 6, with 6 price of the most stable compounds, such as WO3 does not dissolve in water, the air will form in the tungsten trioxide thin protective layer of tungsten, tungsten with fluorine at room temperature, chemical combination, red hot when there is no moisture and Bromine iodide together, red hot when you can and water reaction WO3, at room temperature reaction of tungsten with aqua regia, but the hot concentrated hydrochloric acid and sulfuric acid can only be played with its weak response, but molten nitrate, nitrite, too Hydrogen peroxide, sulfur steam, steam and other phosphorus can play intense reaction, high temperature can not be carbon, boron and silicon reaction of binary compounds, widely used in industrial tungsten steel and tungsten carbide, pure tungsten filament is used to the system, and X-ray tube Tube heating components, semiconductor components can be prepared tungsten silicide, tungsten industrial production is white or black tungsten ore tungsten ore refining.

熔点3410℃，沸点560℃，相对密度1935，F外围电子结构为5d46s2，在化学反应时很容易丢掉1—6个电子，也能得到1—2个电子，所以氧化数为0、±1、±2、＋3、＋4、＋5和＋6，以＋6价化合物最稳定，如WO3不溶于水，空气中的钨会形成薄层三氧化钨保护层，钨能与氟在室温下化合，红热并无潮气时能与溴、碘化合，红热时还能和水反应生成WO3，室温下钨可与王水反应，但热的浓盐酸和硫酸只能与其起微弱反应，但对熔融的硝酸盐、亚硝酸盐、过氧化氢、硫蒸汽、磷蒸汽等能起激烈反应，高温下不能与碳、硼和硅反应生成二元化合物，工业上广泛使用钨钢和碳化钨，纯钨用来制灯丝、电子管和X射线管的发热元件，硅化钨可制半导体元件，钨工业生产是将白钨矿石或黑钨矿石精炼。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
