Objective To investigate the safety and compare the outcome with or without interdicting blood of cesarean with uterus myoma removaling at same time.Methods Retrospective analysis of 117 cases of cesarean with uterus myoma removaling under interdicting blood from 2003 to 2004 and 56 cases without interdicting blood from 1992 to 1994 in Beijing Maternity Hospital for comparison in inhospital days、average bleeding、hemoglobin descending、postoperative morbidity.And 110 cases of simple intraperitoneal cesarean from 2003 to 2004;And comparing uterus myoma in different places and sizes.

目的 探讨剖宫产同时行子宫肌瘤剔除术的安全性及阻断血管与非阻断血管手术的比较方法回顾性分析2003～2004年两年间北京妇产医院腹壁横切口腹膜内剖宫产同时采取子宫血管阻断止血法行子宫肌瘤剔除术117例，与1992～1994年我院行剖宫产同时子宫肌瘤剔除术26例比较平均出血量、血红蛋白下降、住院天、术后病率情况（肌瘤直径≥5cm）；同时与2003～2004年单纯腹膜内剖宫产110例，比较平均出血量、血红蛋白下降、住院天数、术后病率情况；并对不同部位、不同小的子宫肌瘤剔除进行比较。

These viruses themselves are capable of lysing tumor cells selectively, and more importantly, their selective replications will amplify not only themselves but also the carried therapeutic genes in tumor cells.

抗肿瘤新生血管生成是肿瘤治疗的有效策略之一，目前已经有数十种新生血管抑制剂进入临床试验本研究。内皮抑素是目前已知的最强的肿瘤血管抑制因子。

Vascular endothelial growth factoris a new kind of blood vessel active factors was finded in recent years. It not only plays a very important role in the process of micrangium proliferation but also contributs to the stabilizing, maturating and refraining from apoptosis of nascent micrangium, it participates the vascular endothelial cell through specific binding with corresponding receptor.

血管内皮生长因子(vascular endothelial growth factor， VEGF)是近年来新发现的血管活性因子，通过与相应受体结合特异性的作用于血管内皮细胞，不仅在毛细血管增生中起着十分重要的作用，而且对于稳定新生的毛细血管，使之成熟，避免凋亡具有重要意义。

We have shown that folic acid normalizes endothelial function in children with type 1 diabetes who have a similar degree of endothelial dysfunction but, lower total homocyst ine and higher folate status.

我们以前研究显示患1 型糖尿病伴有血管血管内皮功能障碍的儿童，虽然补充叶酸可使受损的血管内皮功能恢复正常，但是导致较低的血浆总高半胱氨酸水平和较高的血清叶酸盐水平。

Methods To use small pig as experimental animal, transfer left gastric omenta vessel to prefabricate left thorax-abdomen flap, use 76% angiografin to do X-ray vesografy. Observe morphology changes.

以北京小型香猪为实验动物，转移胃网膜左血管预构左胸腹部皮瓣，以76％泛影葡胺连续数周做X线血管造影，观察血管在皮瓣内的形态学变化。

The understanding of the distribution, supplying territory, and clinical manifestation of important perforating arteries is paramount importance.

对穿支血管的走行、分布、供应范围的深入理解及术中有效保护和正确处理穿通支血管对手术的效果起着重要作用，根据动脉瘤位置和穿支血管分布的不同，采取不同的手术方式。

Our experiment showed that addition of benzydamine induced vasorelaxation in the denuded aorta precontracted with KCl in the normal krebs.

实验结果亦显示，benzydamine能抑制高钾所引起的收缩作用，并且藉由在无钙之Krebs溶液中，经benzydamine前处理的血管给予高钾刺激之后，再给予钙离子刺激血管收缩，发现其能抑制外钙内流所造成的血管收缩作用。

血管生成是指内皮细胞从已经存在的血管处增殖和迁移并形成新的血管的过程。

Objective: To provide anatomic basis for pectoranis minor muscle transplantation by vessels and nerves anastomosis to reconstruct thumb opposition function. Methods: The blood supply and nerve innervation of pectoralis minor muscle, the comparison of the morphology and dimension of both pectoralis minor muscle and thenar muscle were investigated on 20 sides of adult cadaveric thoraxes and hands. According to the locations of the vessels and nerves of the pectoralis minor, the clipped pectoralis minor muscle at the same side were transplanted and fixed to thenar muscles with the same direction of thenar muscle fiber. After that, the process of dragging simulating opposition movement of hand were performed and observed.

目的：为吻合血管神经的选择性胸小肌移植重建拇对掌功能术式提供解剖学依据方法：在20侧成人胸部及手部标本中，解剖观察胸小肌的血管神经分布及胸小肌和大鱼际肌的形态、大小并将一者进行比较；然后按照大鱼际肌纤维走行方向，参考血管神经位置，将胸小肌修剪合适后移植固定于同侧手部大鱼际，模拟正常手部拇对掌功能予以牵拉，观察标本手部拇对掌过程。

On the sixtieth postoperative day, the graft was harvested and the blood was taken from inferior cava venae. Histological changes were monitored by HE stain. The infiltration of CD4+ and CD8+ T lymphocytes and the expression ofα- smooth muscle actin were detected by immunohistochemistry.

术后60天取移植血管做病理组织学检查并利用计算机图象分析系统测量血管内膜厚度；免疫组织化学检测CD4+、CD8+T淋巴细胞的浸润及α-平滑肌肌动蛋白的表达；ELISA法检测血清中血管内皮生长因子的变化。
