By using a power injector,60 ml of 75% contrast material was injected at a speed of 3 ml/sec via a 17-guage antecubital vein catheter,14 s after start of bolus the dual-phase dynamic CT scans were performed 7 times at the single level.

48例肝肿瘤患者平扫发现并定位病灶后，用压力注射器以3ml／s速度从肘静脉经17号塑料套管针注入造影剂60ml，开始注射后14s行双期动态CT，同层共扫7次。

Objective To investigate the effects on myocardial perfusion of simultaneous antegrade/retrograde cardiopiegia through a single coronary artery and coronary sinus.

目的探讨经单根冠状动脉和冠状静脉窦顺行性／逆行性同时心肌灌注的效果。

Methods: All of 28 severe patients of pulmonary infection were performing mechanical ventilation because of Ⅰ-type of Ⅱ-type respiratory failure. They all accepted the treatment of bronchofibroscope lavage under the monitoring of ECG, blood pressure and blood oxygen saturation. Mean while, the antibiotics and apophlegmatic drug were used too.

对合并严重肺部感染出现Ⅰ型或Ⅱ型呼吸衰竭而行有创机械通气的各种危重症患者28例，均在全身应用抗菌药物、祛痰药的基础上，在实时心电、血压、血氧饱和度、呼吸监测下进行床旁经纤支镜灌洗治疗。

Methods 26 patients with auditory neuropathy were assessed by MASSR; these patients were all diagnosed by behavioral audiometric testing, acoustic impendance, speech perception, ABR and DPOAE.

对26例经纯音测听、声导抗、言语测听、听性脑干反应和畸变产物耳声发射确诊为听神经病的患者，行多频听觉稳态反应检查，并与纯音听阈进行比较。

Results: Because of the early reparation,53 auriculae of patients were alive again.The ratio of success was 82.8%.The temperature,sense and appearance of the auriculae were normal.9 cases of auriculae were alive partially.

结果：53例经修复及再植后完全成活，温度及感觉正常，外观良好，成活率为82.8%。9例部分成活，占全部患耳的14.1%。2例失败，遗留明显耳廓畸形，以后行Ⅱ期耳廓整形术，占全部患耳的3.1%。

In uncircumcised boys older than 7 or 8 years of age with phimosis that is resistant to topical corticosteroids and in boys with phimosis that causes ballooning of the foreskin or recurrent balanitis, strong consideration should be gien to performing a circumcision or dorsal slit.

对于7～8岁以上的、经局部用药无效的包茎患儿，排尿时包皮膨胀起来的包茎患儿以及反复发生龟头炎的包茎患儿，应该考虑行包皮环切术或包皮背侧切开术。

The test bedstand which is composed of electro-motor ,hydraulic pump ,hydraulic motor ,speed verily box and parallel compensating pump, can resolve the problem of power consumption and the power warm while large power hydraulic pump and motor testing.the principle of system is that electro-motor drive the hydraulic pump first,then the pump make the hydraulic motor work through its high pression oil,the follow working hydraulic motor feedback the power in niuju re-drive the hydraulic pump,at last the power is recovered.this bedstand make use of bishi hydraulic system ,which can have a closely construct ,and steadly chuandong ,lower noise ,high power recovery percentage and so on.

本实验台由电动机、油泵、油马达和变速箱以及并联补油泵等一起构成功率反馈实验油路，以解决大功率液压泵及马达在试验时的大功率消耗和能量耗散时的发暖问题。实验台由电动机带动油泵，油泵输出油液驱动液压马达，油马达输出的扭矩通过变速箱传动来回馈给液压泵的输渗入渗出轴，从而实现功率往返收。采用闭式液压系统，结构紧凑、运行平稳、噪声低、功率回收率高；机械补偿，电动机输渗入渗出扭矩经变速箱传动驱动液压泵；液压补偿，并联补油泵对系统的高压油路入行流量补偿。

Methods Ninety NSCLC patients underwent curative surgical resection after integrated 18F-FDG PET/CT and chest breath-hold spiral CT examination. Two experienced radiologists blindedly staged all primary tumors in consensus by CT and PET/CT images.

90例经手术病理证实的NSCLC患者均于原发肿瘤切除术前行18F-FDG PET/CT和胸部屏气螺旋CT扫描，由两名有PET/CT诊断经验的影像医师采用双盲法分别根据屏气CT和PET/CT图像对肿瘤行T分期。

Methods 32 cases suspected bronchotracheal foreign body in children were examined using 16-slice CT with post-processing reconstruction mainly multiplanar reconstrction and virtual branchoscopy.All cases were confrimed with clinical bronchoscopy.

方法对32例气管支气管异物患儿行16层CT检查，结合多平面重建、CT仿真内镜图像分析，全部病例经临床支气管镜证实。

By observing the changes of p53, bcl-2 proteins after treatment, the study also wants to preliminarily research the molecular mechanism of esophageal carcinoma treated with sodium cantharidate.

材料与方法：本实验研究对象选取2002年4月～2003年1月在河北医科大学第四医院拟行手术的食管癌病人，术前均经内镜活检证实为食管鳞癌。
