The petal of Gli CMS crimples.The stamen turns into featheriness, the form of the petal , silk form or degradates. Without anther structure, the carpel, it is protruding that the outer edge grows tumour form.The growing style of stamen and pistil is the adhesion type or the scattered type. The shape of pistil is straight or hooked. The opening style of flower is full-nfolded,half-closed or full-closed.

During en mass retraction of upper anterior teeth with straight wire technique, the length of anterior hook mainly influenced anteroposterior moving pattern of anterior teeth. As anterior hook increased from 0 to 6mm, labiolingual displacements of lateral incisor varied form lingual tipping to lingual translation and lingual controlling root movement, while 3-D displacements of other teeth only increased in account.

3直丝弓矫治技术整体内收上前牙时，牵引钩的长度主要影响前牙的矢状向位移方式：牵引钩长度增加至6mm的过程中，除侧切牙在唇舌向上由舌向倾斜运动变为舌向整体平移和舌向控根运动外，前牙的三维位移只有数量的增大，趋势基本保持不变。

Results The penumatization rate of total or inferior part of middle turbinate correlated positively to the inflammation of anterior ethmoid and maxillary sinuses. Compared with patients with normal frontal sinuses, the vertical diameters of agger nasi cells of patients with frontal sinusitis were larger(11.70±5.50 mm and 8.54±3.67 mm respectivevy, p＜0.01).Compared with patients with normal maxillary sinuses, the Haller's cells of patients with maxillary sinusitis were larger (77.8% and 33.3%,P＜0.05)and the amount of inflammatory Haller's cells of the latter was more abundant than that of the former(91.6±17.8 mm2 and 41.6±12.6 mm2, respectively, P＜0.05). The deviation of uncinate process was one of the factors of maxillary sinusitis .The sizes of ethmoid bullae increased with the soft tissue thickening in anterior ethmoid sinus, the large ethmoid bulla may cause anterior ehmoid sinusitis.

结果 全中甲或中甲下部气化的发生率随前筛、上颌窦内软组织影增厚而升高；有额窦炎组病人的鼻丘气房最大纵向垂径明显大于无额窦炎组(分别为11.7±5.5 mm和8.5±3.7 mm，P＜0.01)；Haller气房在上颌窦炎组和非上颌窦炎组的发生率无显著差异，但前组发生炎症的Haller气房明显多于后组(分别为77.8%和33.3%，P＜0.05)，且前组Haller气房的冠状位截面积明显大于后组(分别为91.6±17.8 mm2和41.6±12.6 mm2，P＜0.05)；钩突角度随上颌窦内软组织增厚而减小；筛泡冠状位截面积随前筛窦内软组织增厚而增大(P＜0.01)。

Methods Ninety-one coronal CT scans of chronic sinusitis were analysed with mutimedia software developed by the authors. Sinus CT images were scanned into multimedia computer and the subtle anatomic structures such as pneumatization of the middle turbinate, agger nasi cell, Haller's cell, septal deformity , maxillary sinus hypoplasia , abnormality of uncinate process and ethmoid bulla and so on were measured.
