"For patients with discrete lesions in saphenous vein bypass grafts, the use of DES reduces short-term angiographic restenosis," said Sheldon Goldberg, MD, of Hahnemann University Hospital, Philadelphia."These results cannot be extrapolated to patients with larger grafts, restenotic lesions total occlusions."

菲律宾Hahnemann大学医院的Sheldon Goldberg说，"对局限的大隐静脉桥血管病变患者DES 可以显著降低造影再狭窄，这一结果不能推广到较大移植桥血管、再狭窄或完全闭塞病变。"

Gross observation and mass changes of the grafts: Corresponding materials were infused subcutaneously, the grafts were removed at 1, 2 and 3 months after transplantation for gross observation and the mass changes.

移植物观察其大体观察与质量变化：各组均将相应材料注入新西兰白兔的皮下，移植接种后1，2，3个月取出移植物观察其大体观察与质量变化。

Then, the volume and morphology of grafts were observed and proliferating cell nuclear antigen expression of mammary epithelial cells in grafts was detected by immunohistochemistry. Experiment two: From 2 to 6 weeks after implanting, B-E〓 or NH1996 with respective dosage of 20ug and 100ug were injected muscularly into four groups of host mice once two days, and the control group was designed without treated with hormone.

结果：1。植入2周和6周乳腺组织形态结构保持完整，植入2周乳腺组织块体积、腺体数目和增殖程度均较植入时明显降低，并以此水平维持至植入6周。2.B-〓对植入的乳腺组织形态学无明显影响，但可引起乳腺上皮细胞PCNA、Bcl-2蛋白表达的升高；B-〓可上调PR，下调ER，说明植入裸鼠的正常乳腺对B-〓有反应，证实模型建立成功。

For wedge grafts the cuts are made at a right angle to the crest. Jones[1] et al. have found that full-thickness iliac grafts harvested with a power saw are stronger than those harvested with an osteotome, presumably because of less microfracturing of bone with the saw.

与髂嵴成直角可切取楔形骨块，Jones[1]等发现以动力锯切取的全厚髂骨块的强度要高于骨刀切取的骨块，可能是因为应用骨刀切取对髂骨块可造成更多的显微骨折。

Wedge grafts or full-thickness grafts may be removed more easily with a power saw; this technique also is less traumatic than when an osteotome and mallet are used.

应用动力锯切取楔形植骨块或全层植骨块较为容易，并且比用锤和骨凿取骨创伤小。

Wedge grafts or full-thickness grafts may be remoed more easily with a power saw; this technique also is less traumatic than when an osteotome and mallet are used.

应用动力锯切取楔形植骨块或全层植骨块较为容易，并且比用锤和骨凿取骨创伤小。

The human preserved cartilage grafts with perichondrium were preferable to grafts without perichondrium.

培养的人的带膜软骨进行异种移植后，其移植排斥反应明显弱于不带膜软骨。

Result: 245 cases had the skin grafts well survived and the wounds repaired with good appearance and function. 18 cases had scattered blisters and piebald changes, but the appearance and function were good. 3 cases had skin grafts necrotized.

结果：245例皮片成活良好，外形及功能恢复满意，18例出现散在水疱及花斑样改变，但外形及功能恢复尚满意，3例术后皮片坏死。

Intimal areas were measured using morphometric analysis of perfusion-fixed vein graft specimens, and intimal thickness was calculated using circumferential measurements. The SMC proliferation was studied by the immunohistochemical detection of proliferating cell nuclear antigen. Expression of MMP-2、MMP-9 mRNA in vein grafts and unoperated control Vein grafts was detected by reverse transcription polymerase chain reaction. Substrate gel zymography was used to determine the proteolytic activity.

分别行HE染色、Verhoeff弹性纤维染色观察组织病理变化，计算机病理图象分析系统测量新生内膜厚度及面积，免疫组织化学方法检测静脉壁增殖细胞核抗原表达以观察细胞增殖情况，半定量逆转录-聚合酶链反应检测静脉壁基质金属蛋白酶-2(MMP-2)和基质金属蛋白酶-9(MMP-9)mRNA的表达，明胶酶谱法检测MMP-2、MMP-9活性，比较各组之间的差别。

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。
