Methods: 1. Experimental laparoscopic liver resection: We selected pigs as experimental models aiming to approach human beings physiological and anatomical condition. After CO2 pneumoperitoneum was established, the ligaments around liver were dissociated. Livers were cut off by the methods such as clamp dissection, microwave tissue coagulator, ultrasound dissector, Ligsure dissection, hand-assisted, short abdominal incision laparoscopy-assisted, and Endo-GIA switcher. The operation time and bleeding volume were compared between different methods of laparoscopic liver resection. The advantages and limitations of different methods were summarized. 2. Clinical laparoscopic liver resection: 15 cases with tumors in segment V of anterior right lobe or segments II, III of left lateral lobe or segment IV of left internal lobe were selected in this study. The liver diseases included hepatocellular cancer, hepatic cavernous hemangioma and hepatic focal nodular hyperplasia. The ligaments around liver were dissociated after CO2 pneumoperitoneum established. Laparoscopic liver resection were carried out by some of the methods combined such as clamp dissection, microwave tissue coagulator, hand-assisted, short abdominal incision laparoscopy-assisted, ultrasound dissector, rotation and suction dissector.

The results are as follows:(1) With the imposing of orthopedic force of simulating maxillary protraction on maxilla, in the sagittal direction, the maxillary complex of the SD Rats in experimental group grows more quickly than that in two control groups, and the extent of the maxillary complex increases more evidently. The maxillary complex displays anti-clockwise forward and upward rotation.(2) With the imposing of orthopedic force on maxilla, upper incisors exhibit labial-inclined, labioclination of lower incisors changes insignificantly, and the shape and the dimension of skull are not affected significantly.(3) The expression of TGF-3 , in frontomaxillary sutures and palatomaxillary sutures shows different intensity in different extent of time. But The expression of TGF-{3, in experimental group is more intensive than that in two control groups, and that in operated control group and natural growth group has no significant difference.

结果如下：在模拟上颌前牵引矫形力作用下，(1)生长发育期大鼠上颌复合体在矢状方向生长加快，长度明显增加，并表现出向前向上的逆时针旋转；(2)上切牙唇倾，下切牙的唇倾度没有明显变化，颅脑的形态与大小不受影响；(3)额颌缝和腭颌缝中TGF-β_1的表达，同一时段实验加力组要强于手术对照组与自然生长组，而手术对照组与自然生长组之间无显著性差异。

With large-scale model tests of open-cut box tunnel and shallow bored horseshoetunnel intersecting orthogonally and obliquely with active ground fissure zone individually, the adaptability of sectionalized tunnel passing through active ground fissure is studied,theresults show that the sectionalized tunnel with flexible joint can bear very large sheardeformation,and the deformation and secondary stress of adjacent sectionalized tunnel underthe action of ground fissure is small,meantime many sectionalized tunnels can eliminatepartly the effect of active ground fissure movement,have a good capability of adapting itselfto the large deformation.

8通过分段设缝的明挖箱形隧道和浅埋暗挖马蹄形隧道分别正交和斜交穿越地裂缝带穿的大型模型试验，对分段设变形缝的地铁隧道穿越地裂缝带的适应性进行了研究，结果表明分段式柔性接头隧道能承受较大的剪切变形，相邻衬砌管段变形和次生应力均较小，同时多段设变形缝具有很好的消化地裂缝变形的效果，从而说明多段设变形缝加柔性接头连接的地铁隧道具有较强的适应地裂缝活动大变形的能力。
