Later, under the untypical parasternal four-chamber view which can thoroughly display the ostium of coronary sinus, the catheter was promoted further to the ostium of coronary venous sinus. Then the echocardiography technician adjusted the transducer of TTE in order to thoroughly confirm the position of the catheter tip. After confirming the position of catheter tip in the coronary venous sinus, the operator inserted the catheter into the coronary venous sinus for 3～4 mm farther. It was noted that if resistance was encountered by operator, the operation must be stopped, which was the same as x-ray fluroscopy as image guiding. TTE guiding His bundle elactric cahteter、high right atrium electric cahteter and right ventricular electric catheter in site: It is difficult using TTE singly since there are too many crossroads in inferior venous.

本研究结果显示，(1)单独应用TTE作为影像学引导进行冠状窦电极导管置放的成功率为93.8％～96.7％，并且应用TTE作为影像学引导放置专用冠状窦电极导管和普通电极导管的成功率和放置时间在统计学上无显著差异；(2)TTE作为影像学引导，除过度肥胖患者外，可完全替代X线引导进行冠状窦电极导管置放，包括鞘管和扩张管的放置、指引导丝在静脉而非动脉内的证实均可由TTE完成引导，且较X线C型臂有一定优越性；(3)TTE结合普通X线胃肠透视机作为影像学导引，可顺利完成心内电生理检查时导管的安全到位，而不需昂贵的X线C型臂，可将心内电生理检查扩大到广大的基层医院；(4)TTE较X线更易和更早期发现介入治疗的并发症如急性心包填塞等，对并发症的防治甚至挽救病人的生命至为重要；(5)动物实验研究表明，TEE可引导射频导管消融术时大头电极导管成功到位。

Background: Peripheral nerve injury is common and serious in clinically. According to the nerve regeneration theory of nerve tropism, neural regeneration room became hot spot for treating nerve injury.Then keep distance between the proximal and distal severed stumps with different conduits and others substance which can promote nerve regeneration ,the room can provid a favourable environment for nerve regeneration. a series of empirical study indicated immunosuppressant FK506 can promote nerve regeneration, chitosan is polysaccharose natural biomaterial , Chitosan is prepared by the N-deacetylation of chitin.

背景：周围神经损伤在临床上比较常见，根据神经趋向性再生理论，神经再生室成为神经损伤治疗研究的热点，即在神经断端之间留出一定的间隙，并套以不同材料的鞘管及其它促进神经再生的物质，为周围神经再生创造良好的再生环境，一系列实验研究表明免疫抑制剂FK506有促进神经再生的作用。

On the base of practical transformer substation main connection, electric components and system circuit model are first formed in the paper; analyze vacuum arc characteristic and medium resume are analyzed, then, according to vacuum chamber physical process of switching AC arc, resume process are divided into three stages: sheath development, neutral particles diffusion and static characteristic, with that, calculating model of medium resume strength is erected and applied in the computing of vacuum circuit breaker interrupting transform overvoltage; In the paper, Saber software is used to simulate a whole switching process; As follows, overvoltage characteristic of vacuum circuit breaker switching no load and load transformers, kinds of influence factors are analyzed in detail; At last, vacuum circuit breaker switching capacitance group overvoltage formative causes and electrode refining for lessening reignition are discuss.

本文针对中低压变电站的实际主接线建立各电气元件及系统的电路模型；在真空电弧的特点及间隙的介质恢复特性上，依据真空断路器灭弧室分断电弧的物理过程，将真空电弧熄灭后的恢复过程分为鞘层发展、中性粒子扩散和静态特性三个阶段，建立了相应的介质恢复强度的计算模型，应用到切除变压器操作过电压的计算中；采用Saber仿真软件模拟计算真空断路器切除变压器操作过电压；并分别对真空断路器切除空载及负载变压器操作过电压的特点与影响操作过电压的各种因素做了详细的分析；最后简要分析了真空断路器开断电容器组过电压的形成原因及为减少重燃的电极老炼措施。

Results For callus induction of leaf explants of C. orchioides, dark treatment gave better results compared to light treatment; among the media tested, the suitable phytohormone combinations were 2.0 mg/L 2, 4-D or 6-BA 1.5 mg/L 2, 4-D 2.5 mg/L, and 300 mg/L CH 0.2% AC was good for plantlet regeneration from leaf explants. The callus from leaf explants mainly originated from midrib. The parenchyma cells near epicuticle of midrib firstly were initiated to division. Then the parenchyma cells of vascular bundle sheath and mesophyll cells on each side of vascular bundle were also divided to form callus.
