回顾总结我院224例LC的临床资料，分析2例胆管横断损伤的原因及对策。

Couinaud's segmengtation of the liver intransaxial imaging has limitations. Three-dimension(3D)angiography ofportal and hepatic venous systems canbe applied to divide hepatic segment accurately. Hepatic segment analyzed by tracking the branches of portalvein is ofmore clinical value.

传统的横断解剖Couinaud肝脏分段法存在一定缺陷，三维门静脉和肝静脉成像可以用于肝段解剖的划分，采用门静脉属支追踪法对肝段描述可能更有临床价值。

Methods ESCs were collected,induced and marked with green fluorescent protein before transplantation.6 healthy adult cats were randomly divided into 2 groups,normal transplanted group and spinal cord hemisection transplanted group(n=3/each group).

结果绿色荧光蛋白标记的胚胎干细胞的阳性率为38%，半横断移植组未见到荧光细胞，正常移植组可看到荧光细胞并迁移一段距离。

Materials and Methods: Forty Sprague-Dawley rats were randomly divided into normal group, control operative group and operative group which includes 6 subgroups (1,3,7,14,21,28 days). The spinal cord hemisection injury model was made by cutting the posterior right side spinal cord. Function changes in the right posterior limb were evaluated by BBB method. The general morphology changes were observed by HE stain.

材料与方法：40只成年SD大鼠随机分为正常组，假手术组和手术组，手术组又分成1，3，7，14，21，28天组，选取制作脊髓右侧半横断损伤模型，BBB法进行右下肢功能评分，HE染色观察损伤脊髓不同时段的大体形态学变化，原位杂交法观察slit-2 mRNA的表达变化，计算阳性细胞灰度值，进行统计学分析。

Due to the cross-sectional design it is also important not to draw causal inferences, for example, with regard to the relationship between EI and psychopathology.

由于是横断研究设计，不能进行因果推论（如不能对EI和精神机能障碍的相关关系进行因果推论），也是一个非常重要的问题。

Methods: Twenty-four wooden sticks of the chestnut were divided into four groups randomly. Every stick was cut transversely in the median and a twelve-hole dynamic compression plate was attached by screws. Three sensor gauges were installed on each plate to evaluate strain.

用二十四根栗木(chestnut/castaneamolliss)条，样本随机分成四组，每组六条，每根栗木条模拟横断骨折，一块十二孔的动力加压钢板对称性固定，固定位置：A 组固定1-2-6；B 组固定1-3-6；C 组固定1-4-6；D组固定1-5-6。

Thirty wooden sticks of the chestnut were divided into five groups randomly. Every stick was cut transversely in the median and a twelve-hole dynamic compression plate was attached by screws. Three sensor gauges were installed on each plate to evaluate strain.

用三十根栗木(chestnut／castaneamolliss)条，样本随机分为五组，每组六条，每根栗木条模拟横断骨折，一块十二孔的动力加压钢板对称性固定，固定位置：A组固定1—6，B组固定1—2—6，C组固定1—2—3—6，D组固定1—2—3—4—6，E组固定1—2—3—4—5—6。

Correlation between the two observers\'gradings was evaluated using analysis of Spearman. and P.05 was thought significance statistically.2 for the second objective of the study, 25 patients underwent helical 0.5mm axial CT, then the helical data was reconstructed with 0.5 mm slice width /increment and with 1.0 mm slice width /increment respectively, 15 abnormal structures of temporal bone were evaluated by a observer using a modified Likert scale, with unknown of the methods of imaging.

检验标准采用P＜0.05.2对25例耳病患者行0.5mm准直多层螺旋CT扫描，将获得的容积数据以0.5mm层厚层距和1.0mm层厚层距各行横断和冠状重建，由一位神经影像诊断医师按照改良Likert scale评分标准对两种图像独立盲法评分。

南极罗斯岛及泰勒谷地区位于东、西南极二大构造单元的接合部，毗邻横断南极山脉，从第三纪以来，该区构造、岩浆作用非常活跃。

Ross Island and Taylor Valley, Antarctica, are located on the juncture area between East Antarctica and West Antarctica and in the vicinity of Transantarctic Mountain . In this area, tectonism and magmatism have beeen active since Tertiary.

南极罗斯岛及泰勒谷地区位于东、西南极二大构造单元的接合部，毗邻横断南极山脉，从第三纪以来，该区构造、岩浆作用非常活跃。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
