Around the water, soil, food, air, temperature, humidity is different, and gastrointestinal Lawton not meet the road caused by decreased gastrointestinal function, coupled with the not suited to food and drink, so upon their arrival in a new place easily acclimatized.

Method］from january 2003 to may 2006,32 patients were corrected with qin si-he's orthotics devices on the ilizarov principle of tension-stress,which involved 15 males and 17 females,the age ranged from 10 to 25 years.among these patients,2 were caused by peroneal nerve injury,l by tumor in the vertebral canal,5 by meningocele,11 were caused by poliomyelitis,13 by congenital talipes equino-varus.in accordance with deformities,external fixator and limitied operative methods were dertermined.the limited release of soft tissue were performed in 7 patients,limited osteotomy in 25 patients.the dynamic muscle balance operation were performed in 9 patients with imbalance of muscle strength.according to the ilizarov technique,the fixative rods were installed.the telescopic rods on the apparatus were rotated one week after the operation,the divices had corrective function in three-dimensional directions.the deformity of talipes equinovarus,internal rotation and drooping of the forefoot were gradually corrected,and the patients could bear weight and walked on the deformed foot.the mean duration of traction were 42 days,then removed the external fixator maintained with plaster for a site time.

方法］2003年1月～2006年5月，根据ilizarov张力应力法则，应用秦泗河改良的外固定矫形器，遵循ilizarov穿针固定的基本原则，共手术治疗马蹄内翻足32例，男15例，女17例；年龄10～25岁，平均17岁。病因：腓总神经损伤2例，腰椎管内肿瘤1例，硬脊膜膨出5例，小儿麻痹后遗症11例，先天性马蹄内翻足13例。术前用足掌的前外缘负重行走者11例，用足的外缘或足背外侧负重者21例。根据马蹄内翻足畸形程度、性质和患者年龄，确定实施有限矫形手术的方法和外固定矫形器治疗。本组7例同期实施有限的软组织松解术，25例同期实施了有限的截骨术和跗骨间关节融合术，9例合并踝关节内外翻肌力明显失衡者，同期行足部肌腱转移的肌力平衡术。然后安装外固定矫形器。术后按作者制定的管理程序，7 d开始旋转相应的螺纹牵拉杆，对器械进行三维空间的缓慢调整，先矫正前足内收和后足内翻，后矫正足下垂畸形，直至达到矫形要求的标准。在矫形的过程中定期进行x线检测，以防止发生踝关节前后移位，治疗期间允许患足负重行走。术后平均牵伸42 d，拆外固定器后患足再上石膏固定适当时间。

Merismatic cells mainly derived from the inside of RBM, and belonged to ingenesis. With the ceaseless growth of small cell group, the outer layer cells apop tosis gradually. Finally the buds broke through RBM and became young plants.

Tracheal autograft wrapped in one-side sternomastiod muscule flap and two-side stemohyoid muscle flap based on different pedicle can acquire enough blood supply, and are revascularized.

以上方或下方为蒂的单侧胸骨乳突肌瓣和双侧胸骨舌骨肌瓣不管采用何种方式包裹移植气管，均能使移植气管获得可靠的血运，发生再血管化，使实验动物长期存活。

Patients who fail to re ond to rest and su ortive measures must be carefully reexamined to rule out development of neurologic compromise.

Results A followed up for 12 months, one was broken again and restored, the rest were good without gingival congestion and atrophy, with good prosthetic restoration function, no dental root fracture and apical paradentitis.

结果 本组22颗牙，随访12个月，1例发生再折断，再次修复，其余21颗牙龈无充血及萎缩，修复体功能良好，未出现根折及根尖周炎表现。

Five chalcones were synthesized via the aldol condensation reaction of acetophenone or parasubstituted acetophenones with 1-phenyl-3-methyl-5-phenoxyl-pyrazol-4-aldehyde, which reacted with two kinds of hydrazine in glacial acetic acid under refluxing to give a series of bipyrazoline derivatives. In this synthetic course, glacial acetic acid is not only a solvent, but also a catalyzer.

以1-苯基－3-甲基－5-苯氧基－吡唑-4-甲醛为原料，与苯乙酮发生羟醛缩合，生成相应的查尔酮，再在冰醋酸中与不同的肼反应，高产率的合成出10种新的5位含1-苯基－3-甲基－5-苯氧基－吡唑基的吡唑啉类衍生物。
