Therelative rates of the Rh-mediated carbenoid insertion into the benzylic C - H bonds of aseries of para-substituted phenyl substrates: methyl 2-diazo-3-oxo-6-(4-substituted phenyl)-4-propylhexanoate 47a - g, have been measured by an indirect intramolecular competitionmethod under the condition in which the possible steric and conformational effects have beenminimized.

为了将立体因素和构象因素最大程度减小，以便较为准确地评价电子效应对该反应的影响，设计并合成了不同对位取代基的化合物4-丙基-6-(4-取代苯基)-2-重氮基-3-氧代己酸甲酯47a-g，并研究了它们在不同Rh催化剂作用下的分子内C-H插入反应。

Some patients had suffered from obstructive jaundice, pancreatitis, bilirubinemia, alkaline phosphatase raise,γ-glutamyl transpeptidase raise and/or diameter of common bile duct exceeded 0.8 cm; and for these cases intraoperative cholangiography must be carried out. 405 cases needed T-tube insertion. The common bile duct of 105 cases was sutured without T tube. Results All cases were operated successfully.

术前确诊者，术中直接行胆总管切开胆道镜取石；术前有黄疸史、胰腺炎史和直接胆红素增高、胆系酶增高者，或胆总管在0.8 cm以上者行术中造影，明确有胆总管结石的切开胆总管胆道镜取石。405例置T管引流，105例行胆总管Ⅰ期缝合。

One was the pqsA' positive expression plasmid constructed by cloning the pqsA'-lacZ fusion digested from pYHP441 into miniCTX-1, whose sequence was then integrated into wild type PAO-1 chromosome by biparental mating procedure. The other was pqsA-E operon knock-out plasmid whose sequence between pqsD and pqsE operon was inserted by tetracycline cassette by the site specific insertion mutagenesis strategy and the mutant constructed by biparental mating of S17-1 that harbored the plasmid and pqsA' positive expression mutant.

一种是酶切质粒pYHP441获得pqsA'-lacZ片段后，亚克隆入质粒miniCTX-1中，构建成PqsA'的阳性表达质粒，随后将构建的质粒，通过双亲交配过程整合入野生型铜绿假单胞菌株PAO-1染色体组中；另一种是通过点特异插入诱变策略，将四环素基因盒插入启动子pqsD和pqsE之间，构建的阴性质粒转化入大肠杆菌S17-1株后，和上述pqsA'阳性表达突变株进行双亲交配过程。

Every complication has its pathologic and clinical characteristics.Conclusion Many measures are important for reducing complications including strict surgical manipulation, proper selection of good implants, preferred submuscular insertion, whole capsulectomy for prosthesis rupture or leak and through hemostasis, proper bandage, massage and follow-up et al.

严格执行无菌操作、熟练掌握该术技能、选择优质假体、首选胸大肌下置入、对假体破裂或渗漏而再次手术者须尽量完全切除包膜并彻底止血、术后正确包扎按摩以及术后重视随访监测等综合措施，是避免和减少隆乳术后并发症的关键。

Historically, when plexus is not encountered, readjustment ofthe needle insertion point more caudally has been recommended.

以前，没有碰到骶丛的话，推荐重新调整进针点使其靠近尾部。

For these reasons, as well as the additional cost, we do not recommend routinely cementing femoral components designed for cementless insertion.

由于这些原因以及额外的费用，常规将设计成无骨水泥固定的股骨假体用骨水泥固定的做法不值得提倡。

This technique can also be applied to acetabular defects when compressed graft is used to fill the defect followed by insertion of either a cemented or cementless acetabular component.19

该技术也能用于髋臼缺损，使用打压的移植物去填充插入骨水泥型或非骨水泥型假体后形成的缺损。

The abdominal wall in the left lower quadrant, 2 finger breadths (3 cm) cephalad and 2 finger breadths medial to the anterior superior iliac spine, has been shown to be thinner and with a larger pool of fluid than the midline and is usually a good choice for needle insertion for performance of a therapeutic paracentesis.27 The right lower quadrant may be a suboptimal choice in the setting of a dilated cecum or an appendectomy scar.

在过去，常常将腹部正中线耻骨与肚脐中间定为穿刺点，现在，由于腹腔穿刺引流大量液体以及腹中部脂肪厚度增加，左下腹成为腹腔穿刺部位（表1），在左下腹部中线至髂前上棘连线上2指宽（3cm）与距髂前上棘2指宽，已经显示较中部脂肪少及腹水较多是治疗性腹腔穿刺好的首选部位27，在盲肠有扩张或阑尾切除术后瘢痕时右下腹是次选的穿刺部位，应避开腹壁下动脉，这些血管走行在耻骨与髂前上棘之间的中线然后在腹直肌中向上行走，，腹壁可见的侧支循环亦应该避开，腹腔镜检查发现侧支循环可出现在中线并且在腹腔穿刺时有导致血管破裂的风险28。
