Methods OPCAB were perfomed in 33 patients of left main with three-vessel coronary disease. The left internal mammary artery was used to be the graft vessel to anastomose with left anterior descending. The saphenous vein was used to be the graft vessel to anastomose with left circumflex coronary artery, right coronary artery/posterior descend artery, diagonal branch, obtuse marginal branch.

方法对33例左冠状动脉主干合并3支血管病变患者施行了OPCAB，用左乳内动脉作为移植血管与左前降支进行吻合，大隐静脉作为移植血管分别与回旋支、右冠状动脉/后降支、对角支和钝缘支进行吻合。

In approximately 50% cases,A_1 were curved in their courses.A_1 passed across the optic nerve or optic chiasma to the longitudinal fissure where they communicated with the opposite ant.cereb,art.b...

返动脉以一支型和两支型多见，多数起源于前交通动脉平面的大脑前动脉(52.53±2.89%)，通常平行于 A_1的前外侧方，但也有几种复杂的行程，手术时应予注意。

Left circumflex arteries,8 right coronary artery .

有 3 0例 3 9支冠状动脉显示程度不同的狭窄，其中左主干病变 2支，左前降支及分支病变 2 0支，回旋支病变 9支，右冠状动脉病变 8支。

Results:50 patients with lesions associated with anterior descending artery was 35,and the right coronary artery 19,circumflex 10.26 patients with single-vessel disease,18 patients with double-vessel disease,and three lesions 6,the survival rate of PCI is 98%.we follow up from 6 to 40 months after surgery,Chest pain occurred again in 7 patients, 3 patients performed PCI, and 1 case had stent obstruction,1 case died of AMI.

结果：50例病变相关动脉为前降支35处，右冠状动脉19处，回旋支10处。单支病变26例，双支病变18例，三支病变6例；PCI成功率98%；术后随访6～40个月，7例再次出现胸痛发作，3例患者行PCI术，其中1例为原有支架闭塞；急性心肌梗死死亡1例，为心肌梗死后心功能衰竭。

Results:When unilateral anterior superior iliac spine loaded by transient stress,0-10 ms,stress distributed from posterior superior iliac spine to anterior superior iliac spine,and on the last 10 ms,there were greater stress distribution around cacroiliac joint,acetabulum and pubic branch.When unilateral positive backside of ilium loaded,between 0 ms and 20 ms,stress transmitted along vertical direction of ilium,and after 20 ms,there were greater stress distribution on cacroiliac joint,both pubic branch,ischium branch and acetabulum.

结果：冲击载荷作用于单侧髂前上棘时，0～10ms主要的应力沿髂后上棘到髂前上棘分布，在冲击后期10ms以后，骶髂关节、髋臼和耻骨支都会产生较大的应力分布；作用于单侧髂骨正后方部位时，0～20ms主要的应力沿髂骨纵行传导，应力分布并没有在冲击峰值10ms时达到最大，而是从20ms之后，应力开始向骶髂关节、双侧耻骨支、坐骨支以及髋臼等部位传导并可见到明显的应力分布。

The length of attraumatic detachment and transverse diameter between the branches of the flexor digitorum superficialis muscle and the pronator teres muscle were similliar.

结果：正中神经发出的各肌支无典型的分布规律，大部分肌支集中在Ⅴ段、Ⅵ段。旋前圆肌肌支入肌点与指浅屈肌肌支第1支、2支入肌点位置相近，肌支可分离长度、横径接近。

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。

The fascicular group to PT, FCR, PL and AIN can be separated from median nerve in the distal two - thirds of the upper arm, and thereby be selectively repaired and transfered.

骨间前神经和掌长肌肌支、旋前圆肌肌支和桡侧腕屈肌肌支可在臂中、下段从正中神经干分离出来进行修复和移位。

Anastomotic branch passing through the plantar arterial arch and ramus plantaris profundus between the anterior tibial artery and the posterior tibial artery was the widest,its inner caliber was 2.3 mm.

胫前、胫后和腓动脉三者之间在足踝部的吻合支丰富，胫前动脉或胫后动脉之一断裂或栓塞时，只要三者之间在踝足部的主要吻合支未遭受破坏，胫前动脉或胫后动脉远端仍可作为皮瓣受区血管被利用。

Results Fascicles and certain amount (207) of motor fibers from the anterior division of C7 were distributed to musculocutaneous nerve and median nerve, the orientation of these fibers were not clear. The ones (323) from posterior division were to the axillary, radial, and dorsal thoracic nerves, thus the orientation of these fascicles was relatively definite.

结果 大鼠C7神经根前股发出一定数量的运动纤维到肌皮神经、正中神经，总量约207根，但在C7前股定位不明确；后股发出相应的运动纤维束支到桡神经、腋神经与胸背神经，总量约323根，这些束支在C7后股的定位较明确。C7神经根所支配的范围很广，其中以C7后股发出的胸背神经束支支配的背阔肌占比例最大（运动纤维含量＞50%）。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
