Methods: 50 normal Wistar male rats were randomly divided into five geoups: the sham operated group, injury model group, shenjindan capsule treat group, high dose and low dose group (duzhongyaotong pill treat, D and E)(n=10each). Autogenous nucleus pulposus was removed from the coccygeal vertebral and placed into the back of left L5~6 nerve root, The modle of the non-compressive nucleus pulposus protrusion was created by transplanting autogenous nucleus pulposus in the back of left L5~6 nerve roots. At tow weeks, the SP in dorsal root ganglion was determined by immunohistochemistry.

取健康Wistar大鼠50只，随机分为假手术组、模型组、对照组、高剂量组（D组、腰腿理痛散高剂量组）、低剂量组（E组、腰腿理痛散低剂量组），每组10只，将大鼠自身的尾椎髓核取出移植于左侧硬膜外腔L5、L6神经根背侧，造成非压迫性大鼠自体髓核移植硬膜外模型，通过免疫组化的方法测定大鼠2周时DRG中CGRP的变化。

The consolidation and ill-defining diffuse nodule appeared in 8 cases, air bronchogram in 11 cases, bulging of the interlobar fissure in 4 cases,heterogeneous consolidation in 7 cases, cystic airspaces in 6 cases, and the CT angiogram sign in 2 cases, the consolidation were peripherally distributed in 15 out of 18 cases.

结果：18例肺炎型肺癌影像学表现两肺多发性分布7例，叶性分布8例，段性分布3例，所有病例均有实变存在，外周分布的15例，伴有不规则小结节的为8例，空气支气管征的11例，叶间裂向外突出的4例，实变影不均匀分布7例，不规则小囊腔6例，CT血管征2例。

The management for extralobar pulmonary sequestration and bronchogenic cyst located at the extrathorax and mediastinum was simple resection. For congenital adenomatoid malformation, intrapulmonary bronchogenic cyst and intralobar pulmonary sequestration, total lobectomy was done. All the 10 patients are living well now, after from 6 months to 7 years of follow-up.

手术方式为对胸腔外及纵隔腔的支气管囊肿和肺叶外的肺隔离囊肿採取简单切除术；对先天性腺瘤状畸形、肺內支气管囊肿和肺叶內的肺隔离囊肿採取肺叶切除。10例经电话追踪，从6个月至7年不等，其发育、运动均与正常儿童无异。

The lining is an unsealed copper ring; the section of the lining inner cavity is a ladder cavity, the bottom is equipped with an edge shaped via enclosing a crucible; the heating coil is silverly welded in the arc groove of the cylindrical surface of the lining, and the upper of the lining winds a few turns coil around the center of the crucible; the two ends of the composite induction heating device are accessed to a high frequency induction power respectively.

内衬(11)为未封闭铜圆环；内衬内腔的剖面为梯形空腔，底部有装入坩埚(4)的刃形通孔(12)；加热线圈(10)银焊在内衬外圆表面的弧形凹槽中，并在内衬(11)上方以坩埚(4)为中心绕制数匝线圈；将复合感应加热装置(5)的两端分别接入高频感应电源(9)。

The presence of intraperitoneal fluid with a CT density less than that of pure blood strongly suggests extravasated urine in the trauma. Intraperitoneal and extraperitoneal rupture can be distinguished based on location of extravasated urine seen on CT scans.

在创伤情况下，腹膜腔内出现CT值比血液小的低密度液体积聚，强烈提示尿外渗，根据尿外渗的分布范围，CT还可以区别腹膜内和腹膜外型膀胱破裂。
