简介:AbstractCompletion thyroidectomy (CT) is employed after lobectomy when histopathological results mandates total removal of the gland as in case of well differentiated thyroid carcinoma (DTC). It is also employed as a second stage thyroid surgery when unfavorable events occur as in recurrent laryngeal nerve injury or when the surgeon finds out the case is beyond his/her expertise in an attempt to protect the contralateral side and allowing time for recovery or for an expert surgeon to help.

简介:基于资源卫星介绍的遥感数据的解释,这份报纸说事实在Donghai岛的陆地使用区域,位于Zhanjiang的南方,广东省,因为象陆地开垦那样的人的活动,从1986~2010在25年里由576.71hm2膨胀了;同时,在土地的类型的大变化在岛上盖住发生了。在陆地使用的明确的变化在它的生态系统服务价值导致显著转变。因此,由在这使用Costanza方法,quantificationally在它的生态系统分析变化的纸在这个岛上满足;Costanza方法是每统一岛的区域显示出服务价值的一种计算技术。它从1986~2010被发现那,特别在最近的年里,由于在僵化,钢和港口工业,栽培土地的区域,树林,草地和沙漠的快速的发展在不同的度减少了,当时为住处的陆地,工业和交通建设和水和沼泽地的区域增加了。因而,与RMB547.57漠?潦的数字相比?
