穿孔

MTA was used to manage clinical problems. These included pulpless permanent teeth with incomplete root formation and perforation in roots or furcations.

本研究收集了2000—2001年期间在临床上治疗的牙根或根分叉穿孔的病例和根尖未发育完成并牙髓坏死的病例，用MTA修补穿孔和行根尖屏障术，共治疗10例，12颗患牙。

The follow-up periods were various from 6m to 21m. The apical MTA barrier technique was used to manage pulpless permanent teeth with incomplete root formation. The postoperative radiographs showed complete repair of periradicular tissue in 5 of 7 teeth and improvement obviously in other 2 teeth. Only one case (1 tooth) had a 3mm periodontal pocket in four perforation repair cases. The lesion at the perforation sites was improved obviously.

追踪观察时间为6-21月。4例穿孔修补的病例，均为延迟修补，除一例为根尖1／3处的病理性吸收外，其余患牙的穿孔部位位于牙根的冠1／3或根分叉处，一例6m复查时有3mm的牙周袋形成，其余患牙骨吸收暗影均明显缩小。7例根尖发育不全并无髓牙的病例均为成人，5例根尖暗影完全消失，2例明显缩小。

Results There were 3 types of vessel elements,scalariform vessel,reticulated vessel and pitted vessel,the perforation plates were simple perforation plate.

结果茵陈蒿具有梯纹、网纹和孔纹3种类型的导管，穿孔板类型为单穿孔。

The Lithostegia Ching was considered as a member of Peranemaceae for a long time, according to the research,we found that it has the typical scalariform perforation plates,no associated or crossed phenomena,and some region have intact plate,no dimorphic phenomena,no weblike or threadlike remnants,these suggest that The Lithostegia Ching is in a primal evolutional position.

与传统观点不同，我们认为穿孔板仅存在于端壁的管状分子为导管分子，而端壁和侧壁形态、结构相似，有或无穿孔板的管状分子为管胞，蕨类植物中的管状分子主要为管胞。

The results are unsure for experimental use;The rabbit's corneas that were removed with upper-half of corneal limbal epithelium lamella and erased the center corneal epitheliums were transparent with intact corneal epithelium;In the approach,the corneal and limbal epitheliums were burned with a cotton swab socked in 1 mol/L NaOH,there were 4 rabbits' corneal stroma happened perforation or ulcer and symblepharon,and the other one presented corneal epithelium phenotype.This is an applicable method to create the pathological model of corneal limbal stem cell total deficiency.

结果表明，处理后4周，全周角膜缘上皮板层手术切除，中央角膜上皮层用1 mol/L NaOH擦除的5只试验家兔角膜表面全部血管化、结膜化，未发生睑球粘连，角膜基质胶原纤维完整未见溃疡、穿孔等病变，细胞印迹学检查为结膜表型，可作为实验性角膜缘干细胞移植的病理模型；全周角膜缘上皮板层手术切除，中央角膜上皮用生理盐水擦除的5只试验家兔，有2只为结膜表型，另3只为角膜表型，观察期内结果不稳定；半周角膜缘上皮板层手术切除，中央角膜上皮层用生理盐水擦除的5只试验家兔，角膜表面透明，全部为角膜表型；直接用1 mol/L NaOH擦除角膜缘和中央角膜上皮的试验家兔，有4只角膜基质胶原纤维断裂、溶解，并伴有严重的溃疡、穿孔、睑球粘连等病变，不能用于移植试验，另1只角膜表面透明，未见结膜和新生血管长入，细胞印迹学检查为角膜表型。

The follow-up study was carried out towards 87 cases (110 ears) of tympanic membrane perforation repaired by self-body tragus cartilage.

本文对87例（110耳）自体耳屏软骨膜修补鼓膜穿孔进行了远期随访，结果鼓膜穿孔愈合率为88.2％，听力提高15dB以上者占75％，达到应用水平者55.7％。

Treating duodenal ulcer perforation with laparoscopic truncal vagotomy combined with occlusive dressing therapy is an effective way.

腹腔镜下行迷走神经切断术加溃疡穿孔粘堵术治疗十二指肠溃疡穿孔疗效可靠，创伤小，值得推广。

Since 1995 the negatie appendectomy rate has been falling, especially in women, and incidental appendectomies, frequent in prior decades, hae been rarely performed.

非穿孔性阑尾炎的25年下降以及与CT和腹腔镜检查更多运用相关的阑尾切除术增加并不会带来穿孔率的增加。

Ear piercing is the most common form of body piercing.

Ear穿孔是最常见的形式，身体穿孔。

Swelling after piercing is the most common complication and jewelry in place should not be removed until after four weeks after piercing.

穿孔后肿胀是最常见的并发症和地方首饰不应该删除，直到经过4周后穿孔。

Methods: Five patients with parkinsonism or dystonia were assigned to general anesthesia using an modified endotracheal tube.

本实验依照人体实验之相关规定进行，五位患有帕金森氏症或肌张力异常的病人接受神经立体定位手术。
