Conclusin: MRTA as a new imaging technique can demonstrate the relationship between the cisternal portion of facial nerve and surrounding vascular structures, and provides reliable imaging evidence for pathogenetic diagnosis and preoperative examination for MVD

MRTA成像作为一项新的影像学检查技术，能较好地显示面神经脑池段与周围血管之间的关系，从而为面肌痉挛的病因诊断及临床上面神经微血管减压术术前评估提供可靠的影像学依据。

The sensitivity of 3d-tof-mra for diagnosing vascular compression or contact was 88.2%, and the accuracy compared with the surgery was 91.8%. conclusion 3d-tof-mra plays an important role in demonstrating the relationship of the cisternal portion of facial nerve with its surrounding vasculature, and has high sensitivity and accuracy in judging neurovascular compression or contact, which may help to select the proper method for treating patients with hfs. 3d-tof-mra appears to be an important imaging test for determining pathogenesis of hfs.

3d-tof-mra 能清晰显示面神经脑池段及其与毗邻血管的关系，对责任血管的诊断有较高的敏感度和准确度，是面肌痉挛术前病因评估的重要指标，对指导术者探察责任血管，避免遗漏，提高手术疗效等方面具有重要意义。

Methods From May 2007 to Oct 2007, 13 cases of soft foot and ankle tissue coloboma were repaired or reconstructed with this flap. The perforator branch was detected and earmarked by Doppler ultrasound. The flap axis was designed as the connection of internal condyle of tibia and the middle point between inner malleolus and achilles tendon based on anatomy. The pivot was designed in the point which perforator branch perforate the deep fascia. The flap dissociation was performed upon the deep fascia and the flap thickness can be modified during the operation.

2007年5月－2008年10月应用胫后动脉内跺上穿支筋膜蒂皮瓣修复足踝部软组织缺损13例，术前彩色超声多普勒行内深上穿支探测并体表标记，在解剖学基础上，皮瓣轴线在胫骨内侧裸后与内踝、跟腱间中点的连线，旋转点设计在穿支穿深筋膜处，深筋膜上游离皮瓣，术中可根据受区情况适当修整皮瓣厚度。

divided the people in early prenancy into two groups: observation group and control group, each group with 100 people. people in observation group were putted misoprostol 0.6mg in the posterior fornix 2 hours before induced abortion and surface anesthesia in the cervix when operation; people in control group accept traditional induced abortion. then compared the indexs about the extention degree of the cervix, abdominal pain, colporrhagia, operation time, completely abortion rate and adverse reaction after operation, et al.

将早孕患者随机分成观察组和对照组两组，每组100例，观察组人工流产术前2h将米索前列醇0.6mg放置阴道后穹窿，手术时行宫颈表面麻醉，对照组行传统人工流产术，比较两组流产过程中宫颈扩张难易程度，腹痛情况，阴道流血情况，手术时间，完全流产率及术后不良反应等指标。

By the time of its fall, most of the prisoners were writers who had written against the corruptions of the government.
