Methods:the clinic data of 172 cases performed by lc were analyzed retropectovely to disscuss the operation skill and the owoiding of complications.results:there are 3 cases with bile leakage and 5 case with hemorrhage during operation.3 cases were converted to open operations midway with a rate of 1.74%.there are no such severe complications as biliary ducts injury,postoperational hemorrage and bile leakage.conclusions:be familiar with the anatomic variation of cholecystic vessels and biliary ducts,reasonable operation skill,standard manipulation and abdominal operation in time can decrease the complications of lc.

回顾性分析我院172例lc患者的临床资料，就手术技巧与并发症预防进行探讨。结果：术中发现胆漏3例；术中出血5例；中转开腹3例，中转开腹率为1.74％。全组无胆管损伤、术后出血及胆漏等严重并发症。结论：熟悉胆囊血管和胆管的解剖变异，合理的手术技巧、规范的操作、及时果断的中转开腹可以最大限度的减少lc并发症的发生。

Results The whole genome of CVB4 jlu06 strain consisted of 7 395 nucleotides encoding 2183 amino acids, which showed high homologies to other CVB4 strains, with the mutations of 10 amino acids. Phylogenetic analysis proved that CVB4 jlu06 strain showed close relationship to HumanCB4 and POLG_CXB4 strains while showed remote relationship to CXB2 strain. Unlike other non-diabetogenic strains, CVB4 jlu06 strain showed common amino acids with diabetogenic strains at 4 sites in 3A region of non-structural protein.

结果 CVB4 jlu06株基因组全长7395个核苷酸，编码2183个氨基酸，与其他CVB4株的同源性较高，且发生了10个氨基酸的变异，与HumanCB4和POLG_CXB4亲缘关系较近，与CXB2亲缘关系较远；CVB4 jlu06株与具有潜在致糖尿病性病毒株，在非结构蛋白3A区4个位点有共同的氨基酸，与非致病毒株不同。

What's more, the western culture is bumping on its party state system, meanwhile the autocratic tradition is as well making the party state system dissimilate in the operation.

Anatomical studies of femoral endosteal geometry suggest that exact fit of a prosthesis within the cortex is implausible because of large ariations in anatomy and age-related changes in the diameter of the canal.

对股骨髓腔几何形状的解剖学研究表明，由于髓腔的解剖变异相当大并且其直径随年龄而发生改变，故要达到假体与骨皮质完全密贴是不太可能的。

60Co-γray was a useful mutagen in induced mutation breeding .After treated with 60Co-γray ,free-living conchocelis of wild Porphyra haitanensis were induced and represented in offsprings. Purple mutant and excellent practical characters strains were selected from a lot of gametophytic blades. Single cell clone and enzymolysis were used to propagate fast in pure strains of induced mutations.

坛紫菜野生丝状体经一定剂量60Co-γ射线辐照后，子代叶状体发生了变异，经大量培养后筛选出紫色突变体（3号Ⅰ）和经济性状优良的个体（7号Ⅰ和7号Ⅱ），通过体细胞酶解和单克隆技术快速获得诱变选育纯系，并对其主要经济性状进行了研究。

Aiming at the spatial complexity and genesic repeatability of soil salinization in Lower Yellow River Delta, with the application of electromagnetic induction EM38 and its mobile sensing system, spatio-temporal variation of soil salinity in typical field of this region during two critical seasons was analyzed by using GIS and geostatistics method.

针对黄河下游三角洲土壤盐渍化的空间复杂性与发生反复性，运用磁感式大地电导率仪EM38及其移动测定系统，结合GIS与地统计学方法，对该地区典型地块两个关键季节土壤盐分的时空变异特征进行了分析。

Results: the location, shape and number of the sympathetic ganglia were quite variable, and there was 1 to 6 in number unilaterally. Lumbar sympathetic trunk divided into 2-3 branches at the distal part were found in 12 sides. Lumbar arteries were all located under the lumbar sympathetic trunk and the lumbar veins, consisting (68.42+4.35)% situated superficially to the trunk, mainly in L4 arid L5 veins. Genitofemoral nerve pierced psoas muscle at the level of L2-L4 or its intervertebral disc (0.83±0.48) cm away from the medial edge of psoas muscle.

结果：腰交感神经节数目及位置变异较大，每侧1~6个不等；腰交感干可分裂为2~5支，分裂处多在干的下端，本组共发现12侧发生分裂；腰动脉均位于神经干的深面，腰静脉位于腰交感干浅面者占(68.42±4.35)%，以腰4、5静脉多见；生殖股神经穿出腰大肌平面多数与第2~4腰椎或椎间盘对齐，穿出点距腰大肌内侧缘(0.81±0.48)cm。
