胆道

To extrahepatic cholangiocarcinoma and gallbladder carcinoma, the rate of excision is low and the sensitivity to chemotherapy and actinotherapy is poor.

我们的研究表明，胆道癌表遗传的改变能够通过对染色质基因转录的调节来影响癌细胞的增殖进程，而表遗传的改变与蛋白信号的传导密切相关。

Results Compared with conventional ultrasound,sonoCT could suppress the reverberation artifacts in bile duct and gallbladder obviously.Lateral boundaries and adumbration of the carcinomas were improved,resolution of internal structure echos also enhanced.

结果 与传统声像图比较，胆管、胆囊腔内混响伪像明显减弱，提高了肿瘤轮廓的清晰度，增强了病灶内部结构与回声的分辨率，增加了超声诊断胆道肿瘤的可信度。

Lateral boundaries and adumbration of the carcinomas were improved,resolution of internal structure echos also enhanced.Thus,sonoCT raises the reliability of biliary tract tumors diagnosed by ultrasound.

结果 与传统声像图比较，胆管、胆囊腔内混响伪像明显减弱，提高了肿瘤轮廓的清晰度，增强了病灶内部结构与回声的分辨率，增加了超声诊断胆道肿瘤的可信度。

Results The congenital agenesis of gallbladder is rare.It is difficult to distinguish the symptomatic cases from other biliary diseases.

结果 先天性胆囊缺如的发病率很低，有症状组病人与其他胆道疾病的鉴别较困难。

To evaluate the role of computed tomography,in diagnosis of the duodenal ampulla cancer.

目的 探讨影像学方法在胆道壶腹部恶性肿瘤的诊断方面的价值。

Results 25 cases with gailsone, 7 cases with cholangiocarcinoma, 6 cases with carcinoma of head of pancreas, 4 cases with carcinoma of ampulla, 4 cases with cholangitis and 4 cases without disease.

结果 胆道结石25例，胆管癌7例，胰头癌6例，壶腹部癌4例，胆管炎5例，4例未显示异常。

Objective:To evaluate the effectiveness of angiography and embolizati on in diagnosis and treatment of massive hemobilia.

目的：评价血管造影和栓塞对胆道大出血的诊断及治疗效果。

Methods The clinical data of 127 cases of acute ascariasis with ERCP were analysed retrospectively.

方法回顾性分析127例急诊胆道蛔虫病行ERCP的临床资料。

AIM: To study the sphincter of Oddi motility by choledochoscopic manometry, and to investigate the manometric appearance of sphincter of Oddi disorders and its relationship with bile duct stones.

摘要目的：对胆管结石患者术后经"T"管窦道行胆道镜测压，研究胆管结石患者术后Oddi括约肌功能，探讨结石与SO功能变化的关系。

Quantitatively, the optical density of NADPH-d positive neurons in all of the related nuclei was significantly increased in the BDL animals compared with controls. Since NO is thought to be able to increase the motilities of the gallbladder and the sphincter of Oddi in anesthelized rabbits, the elevation of NADPH-d and NOS reactivities is likely to magnify the excitatory effect on the extrahepatic biliary system for the purpose of depletion of the loitered bile juice from the jaundiced liver. These data may also have important implications for the altered state of circulatory, metabolic or regenerative responsiveness under pathological condition.

此现象一来可推测，肝脏在遭受胆管阻塞性黄胆的伤害后，其代谢、血液动态与温度调节作用势必改变、紊乱、甚至失功能，而感觉神经也势必会接受到大量的机械性、化学性、渗透性等感知讯息，所以感觉神经元将一氧化氮制造量提升，有助於感觉讯息的快速传报，以发挥回馈调控的效果；二来可表示，自主神经系统不论是交感或副交感神经，为了因应胆管阻塞所造成肝脏的病变，以增加一氧化氮的制造，意欲刺激肝外胆道系统，排空滞留在肝脏内或胆囊内的胆汁，而达到恢复肝脏内代谢、血液循环、胆汁流动等功能控制的恒定状态。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
