1.Background: Developmental dislocation of the hip (DDH) is currently one of the common musculoskeletal disorders, which have severe impact on the growth and development of children, and their living quality as well. The DDH pathology includes the 3-D spatial abnormalities in bones, cartilaginous and soft tissues. Our previous knowledge about DDH mainly came from the 2-D radiographic examinations, which could not represent the 3-D pathology.
背景 发育性髋关节脱位(Developmental Dislocation of Hip,DDH)是当今骨科领域的常见畸形,患者多为婴幼儿和学龄儿童,该类疾病严重影响患者的肢体发育和功能以及患者的生活质量。
2.Objective : This study was designed to evaluate the directive effect of Three-dimensional computed tomography(3DCT) in the surgery of developmental dislocation of the hip(DDH ) and to provide a reasonable basis of the examination for clinic by analyzing 3DCT findings of the DDH .
目的:通过对发育性髋关节脱位(Developmental dislocation of the hip,DDH)患儿的3DCT影像资料分析,探讨3DCT重建技术对发育性髋关节脱位诊断及手术的指导作用,为临床提供合理的检查依据。
3.Objective To investigate the clinical manifestations and risk factors of the patients from developmental dysplasia of the hip(DDH) family.
目的了解发育性髋关节发育不良(developmental dysplasia of the hip,DDH)家系患者的临床表现及其危险因素。
4.Objective To find a more perfect method of treating developmental dislocation of the hip(DDH).
目的 探讨治疗发育性髋关节脱位 ( developmental dislocation of the hip,DDH)更完善的手术方法。
5.To study the relationship between the age of the patients undergone closed reduction and the development of the acetabulum in patients with developmental dysplasia of the hip (DDH).
目的 婴幼儿髋关节发育不良（developmental dysplasia of the hip，DDH）目前最有效、最简捷的方法是采用闭合复位治疗。
6.PrefaceThe developmental dislocation of the hip ( DDH) is the common disorder in pediatric orthopedics.
发育性髋脱位(Developmental Dislocation of the Hip，DDH)是小儿骨科的一种常见病，髋臼病变相对较重。
7.Abstract:The early embryo developmental block is a common phenomenon in mammal when embryos are cultured in vitro.Many studies of phosphorus,glucose,hypoxanthine and cytoplasmic factors on early embryo developmental block carried out by different methods such as morphology,biochemistry,molecular biology and micromanipulation have been reviewed.The merit and shortcoming were analyzed and the necessity of using simple or components limited media overcoming early embryo developmental block were also reviewed.Media that have been shown effective in overcoming early embryo developmental block in mouse,rat,hamster,rabbit,pig,sheep,cattle and monkey were listed.
摘要哺乳动物胚胎在体外培养中普遍存在早期发育阻滞的现象.对此,人们用形态学、生物化学、分子生物学、显微操作等手段开展了磷酸、葡萄糖、次黄嘌呤和细胞质因素对早期胚胎发育阻滞的影响的研究.本文综合分析了共培养系统的优缺点.说明了采用完全成分已知的培养液对进行有关研究的必要性.列出了有效运用于克服小鼠、大鼠、仓鼠、兔、猪、羊、牛、猴等动物早期胚胎阻滞的成分已知的培养液的名称。
8.In rat segment II experiment, EEA and EE expressed selective developmental toxicities, the A/D ratio were 4 and 3.8 respectively. In rabbit segment II experiment, EEA had selective developmental toxicity and EE had not, the A/D ratio were 4 and 1 respectively. In Hydra Assay, EEA had not selective developmental toxicity and EE had, the A/D ratio were 1 and 5 respectively.
大鼠试验结果表明EEA和EE均有选择性发育毒性,其A/D分别是4和3.8,家兔试验结果表明EEA有选择性发育毒性,而EE则无,A/D分别是4和1,水螅试验结果表明EEA无选择性发育毒性,而EE有,共A/D分别是1和5,因家兔的CE无转化EEA活性,故毒性表达与大鼠不同;
9.Combined with the practice of developmental resettlement in the reservoir area of the Three Gorges Project, this paper discusses the following aspects: the definition of developmental resettlement, its management system, its antecedent work, compensation principles, compensation funds management, rural emigrant movement and settlement, cities and towns movement and construction, rehabilitation of industry and other special items, preservation of cultural relics, ecological and environmental protection, and the post-supply of developmental immigrants.
结合三峡工程库区开发性移民实践，就开发性移民的定义，开发性移民的管理体制、前期工作、补偿原则、补偿资金管理，以及农村移民搬迁与安置、城集镇迁建、工矿企业迁建、专业项目复建、文物保护、生态与环境保护、开发性移民的后期扶持等问题进行了探讨。
10.Over six abnormal developmental evaluating items were found in 89.1% children at age 1 to 6 years old by using Denver Prescreening Developmental Questionnaire(DPDQ for short),and those were not found in the control subjects.
用丹佛发育筛查询问表检查 1～ 6岁脑瘫患儿 ,有 6项以上发育迟缓项目占 89 1% ,而正常儿童无 6项以上发育迟缓者。
