In the past, the surgeons usually adopted ileal ureter plasty or ureter bladder flap plasty （Boari flap plasty） to restorelong-term ureteral mucosal avulsions and long or entire ureteral segment defects caused mostly by ureteroscope operations. But there are still certain difficulties in the restoration of long segment ureteral defects （〉20 cm） using traditional methods. In order to overcome traditional surgical approaches, we designed a new ureteroplasty operation using spiral pedunculated bladder muscle flap to restore long segment ureteral defects. METHODS Six patients who presented long segment ureteral defects caused in the course of ureteroscopic lithotripsy due to ureteropelvic junction stenosis and stones （length of defects： 21-25 cm, mean length： 22.5 cm）, were given general anesthesia, and made to lay in the horizontal position while indwelling triple lumen catheters. These patients had Gibson incision in the hypogastrium of the injured sides, and we could prolong the surgical incision up to the epigastrium or the flank abdomen moderately if necessary. We exposed the retroperitoneal space, transected the umbilical ligaments, peritoneal adhesions, spermaducts or the round ligaments to dissociate the bladder to the maximum extent possible. We could increase the mobility of the bladder by dissociating the contralateral superior vesical arteries along the anterior trunk of the internal iliac artery. We could also identify the stump of the distal ureter along the path between the ureter and bladder below the iliac vessels, and then we had to ligate or transfix the ureteral stump. We dissociated the ureteropelvic junction carefully, trimmed the stump to the inclined plane in order to facilitate the anastomose between the bladder muscle flap and the trimmed ureteral stump while locating and tracting it by the suture. Filling the bladder with 400 ml of normal saline solution along the catheter, we located the anterior wall of the bladder with the suture. Before de

In order to lower the usage of expensive Cyanex 923 and increase the extraction capacity of the system of Cextrant 230,the synergistic extraction of thorium from chloride media by a mixture of Cextrant 230 and Cyanex 923 was *** maximum synergistic enhancement coefficient(R)of 1.53 is obtained at 1:1 molar ratio of Cextrant 230/Cyanex *** syne rgistic extracted species of Th^(4+)is determined as ThCl_(4)·2Cextrant 230·Cyanex *** synergistic extraction of Th^(4+)is an entropy-driven exothermic *** loading capacity of 0.60 mol/L mixed extractant for thorium is about 17.10 g/L(calculated as ThO_(2)),and the loaded thorium in the organic phase can be effectively stripped by distilled *** comparison,rare earth cations are barely extracted under the similar conditions,suggesting that the mixtures can be applied to separate thorium from rare earths.A cascade extraction process was developed based on the synergistic extraction system to separate thorium from the hydrochloric acid leaching of *** content of thorium in the leaching solution decreases obviously from 19.90 mg/L to1.4μg/L by 3 stages of extraction,which is superior to sole Cextrant 230 or Cyanex *** introduction of Cextrant 230 into the extraction system not only lowers the usage of Cyanex 923 but also enhances the selective extraction of thorium at low acidity,implying that the synergistic extraction system can selectively extract thorium more efficiently and economically than the sole systems.

The adsorption of O2 over defective La2O3-based OCM catalysts with anionic vacancies , and the reaction of surface oxygen species with CH4 were studied by means of in situ confocal microprobe Raman spectra. The partially reduced oxygen species O2, O , O (O<&<1 ) and even the lattice oxygen ion O2-can be detected on the surface of O2-pretreated La2O3-based catalysts. At lower temperatures (< 573 K) it is peroxide species O- or O- that is more essential for the coupling of methane,while at higher temperature. the superoxide O2 and lattice oxygen species O2-are rather important. It is easier for fluoride-containing La2O3-based catalysts to induce the oxygen species with fewer negative charges and the basicity of the cat- alyst surface is weakened , so that the C2 selectivity for OCM reaction is improved.

It is one of the key points for modernization and internationalization of traditional Chinese medicines to construct the Good Agricultural Practice (GAP) base of Chinese materia medica (CMM). GAP helps to minimize contamination and improve the quality of CMM during the plantation and the production of Chinese crude drugs. In this article, the status and development of CMM production bases of GAP in Guangdong Province, China, are presented. The suggestions upon the problems during the development of GAP for Chinese crude drugs are also provided.

Metal exsolution engineering has been regarded as a promising strategy for activating intrinsically inert perovskite oxide catalysts toward efficient oxygen evolution *** metal exsolution processes on perovskites are often achieved by using the reducing hydrogen gas; however,this is not effective for the relatively stable phase,such as Ruddlesden-Popper perovskite oxides.
