Objective Observe and compare the results of malposed teeth treated with orthopedic treatment, which caused by periodontal disease, in maintaining the periodontal health aspect.

本研究中48名患者男18名，女30名，年龄25-40岁，平均年龄32岁，所有患者均患有不同程度的前牙病理性移位、松动、牙根外露等牙周病史。

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。

Results Maxillary first and second molars were more mesially inclined in the first group, particularly in the younger subjects (16～25 years).

用U检验对两组测量角度的平均值进行比较，Spearman 相关系数估计年龄因素的影响，用Logistic回归分析第三磨牙的萌出与第一磨牙、第二磨牙的轴倾度、性别和年龄之间的关系。

In connection with the age-metallicity relation, we confirmed the Edvardsson et al's discovery of a substantial dispersion imposed on a weak correlation between age and metallicity; this result is also valid for the age-kinematics relation.

首先，我们的研究进一步证实了Edvardsson等人发现的结果，即在年龄和金属丰度关系中存在相当大的弥散。这种弥散也存在于年龄和动力学关系中。

Meanwhile the SHRIMP zircon U-Pb age of the fine-grained monzonitic granite is (131.4±1.6) Ma. These precise dating results represent the ore-forming period of this molybdenum deposit, the main dominant geological events and suggest its close relationship with buried Yanshan fine-grained monzonitic granite.

文章通过采集WZK1钻孔211.2~214 m细脉浸染状矿石的辉钼矿纯样，获得辉钼矿的等时线年龄为(134.1±3.3) Ma，并对比了矿区细粒二长花岗岩的锆石SHRIMP年龄(131.4±1.6) Ma，两者基本一致，表明矿床的形成主要与隐伏的燕山期细粒二长花岗岩有着密切关系。

The preoperatie symptoms before ACDF were myelopathic symptoms in 24 patients, nonmyelopathic symptoms in fie patients, and unknown in two patients. The adjacent lesions were spondylosis in 27 patients and disc herniation in four patients, and they occurred in the superior segment in 21 patients and in the inferior segment in 10 patients. Thirty-one age- and sex-matched patients with cerical spondylotic myelopathy who underwent ELAP during the same period, who gae no history of surgery on the cerical spine, were enrolled as controls (group B; 26 males, fie females; mean age: 58 years).

ACDF术前24例患者有脊髓病症状，5例为非脊髓病症状，2例患者为不名症状。27例和4例患者相邻节段损害分别是颈椎病和椎间盘突出，并且21例患者发生在上位节段10例在下位节段，31例年龄和性别相符患有脊髓型颈椎病而又没有脊柱手术史的患者在同一时期行ELAP者被计入对照组（B组：26例男性，5例女性；平均年龄58岁）。

Age is an important factor affecting the level of NAA in frontal white matter.

年龄是影响额叶白质区域NAA含量的重要因素，随着年龄的增大，NAA含量会逐渐下降，性别和半球偏侧化对额叶代谢物浓度没有影响。

Simultaneously 15 samples of normal nephric tissue were used as control.The sections from these samples were subjected to immunohistochemical analysis with antibodies directly against uPA and PAI-1 by LSAB method. In this study we adopt semiquantitative analysis to determined the expression of these molecules , and utilized the relevant data processing and statistical analysis to evaluate the correlation between their expression and the clinicopathological features of RCC.Results: 1. The positive rate of uPA and PAI-1 of uPA in RCC were 72%(36/50)and 56%(28/50), respectively.But in control group there was nearly

正常肾组织标本中几乎无阳性染色。2、uPA表达水平与患者年龄、性别、肿瘤病理分级无关(均P＞0.05)，与T分期、淋巴结转移有明显的相关性(r=0.684，P＜0.05；r=0.789，P＜0.05)，uPA高表达多见于T_(3-4)、有转移的RCC.3、PAI-1的表达水平与患者年龄、性别、肿瘤病理分级和T分期无关(P＞0.05)，与淋巴结转移有明显的相关性(r=0.800，P＜0.05)，PAI-1高表达多见有转移的RCC.4、对uPA和PAI-1行相关性检验，uPA在RCC中的表达与PAI-1的表达呈明显正相关(r=0.168，P＜0.05)。5、uPA和PAI-1的表达与淋巴结转移的关系以Logistic回归法进行分析，结果显示uPA与区域淋巴结转移密切相关，uPA是淋巴转移的危险因子(RR=2.718，95％CI=1.150～7.170，P=0.024)，PAI-1则不是淋巴转移的危险因子(RR=1.599，95％CI=0.624～4.102，P=0.328)。
