Abstract］ objective to evaluate the use of a pressure phosphene tonometer in measuring intraocular pressure after laser in situ keratomileusis. methods fifty eyes of 25 consecutive patients who underwent lasik surgery were enrolled in this study. among them, 12 were male and 13 were female.

目的 评价压眼闪光眼压计(pressure phosphene onometer，ppt)在准分子激光原位角膜磨镶术（laser in situ keratomileusis，lasik手术前后测量结果的准确性，并与非接触式眼压计（noncontact tonometer，nct）相比较，探讨其临床应用价值。

Methods:43 patients including 10 with mitral stenosis associated aortic regurgitation, 12 with mixed mitral valve lesions and 21 with mixed mitral valve lesions and combined with aortic regurgitation were studied.MVA determinded by (1) two -dimensional echocardiography with a cross-sectional area in the short-axis view (2DE),(2) pressure half-time using formula of 220/PHT,(3) color Doppler flow imaging with a jet cross-sectional area in the short-axis view with planimetry,(4) CDFI with a color jet width at the mitral valve orifice in the apical four-chamber view and long-axis view, assuming an elliptic mitral orifice, compared with the orifice area of excised mitral valve during mitral valve replacement.

材料与方法∶分别用二维超声(2DE)、压差减半时间、彩色多普勒二尖瓣口血流截面积和椭圆形面积法测定43例风湿性心脏病二尖瓣狭窄拟行人工瓣置换术患者的MVA，其中合并主动脉瓣反流 10例，合并二尖瓣反流 12例， 21例，并与手术标本的实测面积相比较。

To serious evaginate, at the same time companion has chronic conjunctivitis, repair is very difficult, the effect really nap method, violate with the desire photograph of hairdressing again, as follows the partial excision of eyelid board, meet those who cause next eyelid shorten, change eye form; And valve of skin-grafting, skin transplants, can stay again apparent and ugly trace, the evaginate issueing eyelid after operation of this shows pouch is in again prevent.

对于严重的外翻，同时伴有慢性结膜炎的，修复十分困难，效果确实的修整方法，又与美容的愿望相违背，如下睑板的部分切除，会造成下睑的缩短，改变眼形；而植皮、皮瓣移植，又会留下明显而又难看的痕迹，由此可见眼袋手术后的下睑外翻重在防止。

Briefly, we use double CCD of computer vision to detect the space position of a small permanent pellet in the Magnetic Stereotaxis System.

本论文基于普通机器视觉模型，采用计算机软件和图像采集系统相结合的方法来对磁导航定位手术系统中兴趣物体的空间位置进行检测。

Methods After retrospective analysis on CT and MRI carried out on 57 patients admitted in our department diagnosed as uncinate process carcinoma of pancreas, assessments were made on whether tumors can be resected or not.

回顾性分析1996年1月－2005年12月我科收治的57例胰腺钩突癌患者的CT及MRI表现，据此判断肿块能否切除，并将其结果与实际手术及病理报告相对照。

The direct CT signs of carcinoma of vaters ampulla is finding mass in the region of Vaters ampulla,and it is a reliable and effective method to diagnosis and the distinction diagnosis of ampullary carcinoma with the combination of the spiral CT scanning of thin-slice and image post-processing technology,and it offers important guidance role to its operation treatment.

壶腹部肿块是乏特氏壶腹癌的CT直接征象，应用螺旋CT薄层增强扫描与图像后处理技术相结合对壶腹癌的诊断和鉴别诊断是可靠而有效的方法，并对其手术治疗提供重要的指导作用。

The section thickness was 5mm,the best section was selected before injection of nonionic contrast material, hen nonionic contrast material l.5m1/kg were injected via the antecubital vein in the rate of 2ml/sec, two serial scannings were obtained began at 6s and 2mm, for the first series the scanning internal was 3 seconds, for the second series, the scanning internal was 7 seconds.3 Methods of studying figureThe CT numbers of lesion on plain CT and on contrasted CT at serial phases were recorded, on which the time-intensity was produced.

计算出不同时相时的CT增强值，绘出动态增强曲线。在不知道病变病理结果的情况下，由三位有经验的医师在不知道病理结果的情况下记录上述病例的动态增强模式及其动态变化。 4。增强峰值与肺血供来源和血管密度的关系的评价其中32例准备手术的SPN，术前行CT同层动态增强扫描后测量增强后第一次循环肺动脉期与主动脉期CT值。然后分别与平扫时CT值比较；术后对瘤体CT测量兴趣区取材并行HE染色，随机取5次，在放大40倍的显微镜下观察5mm范围内直径0.02～0.1mm和＞0.1mm的微血管数目，5次的平均值颀士学泣衫艾中文赂要即为兴趣区对应的血管数目，井将其与瘤体增强峰值作相关性分析。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
