Methods CIT model with BIMⅡ Bioimpactor was used to observe the changes of the mean blood velocity,mean blood flow and the diameter of the inferior vena cava,abdominal aorta,superior mesenteric artery,hepatic artery,hepatic vein,portal veinand renal artery at preinjury,1h,4h,8h and 24h postinjury with Doppler echocardiography in 20 rabbits.

随机选取家兔20只，雌雄不限，采用BIMⅡ型生物撞击机致成CIT模型，分别在伤前、伤后1、4、8、24小时利用超声多谱勒检测下腔静脉、腹主动脉、肠系膜上动脉、肝动脉、肝静脉、门静脉和肾动脉平均血流速度、平均血流量和血管内径。

CT Findings were as follows : pancreas enlargement in 24 cases , focal and diffused hypodense in 39 cases , hemorrhage and necrosis of pancreas in 3 cases, peripancreatic effusion in 39 cases , prerenal fascia thickening in 39 cases , pleural effusion in 24 cases , with thrombosis in portal and SMV in 1 case . A case of pancreas head enlargement misdiagnosed for tumor,a case pancreatitis effusion was through superficial inguinal canal into scrotum.

CT影像学征象如下：胰腺体积增大24例；局限性及弥漫性密度减低39例；胰体及尾部出血坏死3例；胰周间隙渗出39例；肾旁筋膜增厚及脾肾间隙模糊39例，特别是左侧肾前筋膜均累及；少量胸腔积液24例；出血性胰腺炎伴门脉及肠系膜上静脉血栓1例；炎性渗出物通过腹股沟管蔓延到阴囊1例；单纯胰头增大，误诊为胰头肿瘤1例；本组40例中合并胆石12例。

Methods Male Wistar rats were allocated to two groups:In group A,total hepatic ischemia with portal congestion was induced by Pringle′s maneuver for 15 minutes.

Wistar 系雄性大鼠，随机分成两组：甲组：肝门阻断15分钟；乙组：先在右颈内静脉与盲肠静脉之间做一分流以消除门静脉淤血，然后阻断肝门血流15分钟。

Hepatectomy,regular or irregular,under occlusion of the portal triad by Pringle maneuver is an important technique for treatment of severe liver trauma.

肝后静脉损伤的主要对策是全肝血流阻断或转流下肝切除或肝切开显露和修补肝后静脉；难以耐受此术式时，肝周填塞是明智的选择。

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.
