Methods:Twenty-three patients with CAOD awaiting bypass operation were observed as research group.Thirty-one patients undergoing elective open repair of an infrarenal abdominal aortic aneurysm were observed as control group. Clamping and declamping arterial for anastomoses were served as ischemia reperfusion injury. LDH, CK, MB as indicators of skeletal injury before operation and first 3 days after operation were detected.

以接受旁路手术治疗的23例慢性下肢动脉闭塞患者为试验组，以接受腹主动脉原位置换的31例腹主动脉瘤患者为对照组，以术中阻断及开放血管为急性IRI因素，以乳酸脱氢酶、肌酸激酶、肌红蛋白为检测指标，研究两组骨骼肌对急性IRI的反应。

The study of Constitutional science must be from normative analysis constitution to constitutional interpretation, the reason is that normative analysis constitution has an insolvable tension between fact and norm, namely, value and fact, availability and actual effect, norm and interpretation.

中国宪法学50年之发展，自注释宪法到规范分析宪法，其方法论已经发生了具有转折性的置换，但宪法学研究之所以需要从规范分析宪法到宪法解释学，实乃规范分析宪法学在事实与规范之间始终存在着难以逾越的张力，从而必然会导致价值性与事实性、有效性与实效性以及规范性与解释性的分离与脱节之弊。

The huge interarticular contact force of artificial atlanto-odontoid joint at shear and flexion/extension will bring about abrasion, mobilization and destruction of bone or prosthesis. There is potential instability in rotation after replacement operation.

人工寰齿关节置换术后前后向剪切和屈伸运动时人工寰齿关节间的接触应力过大，易造成磨损、引起假体松动和骨或假体的破坏；并且潜在旋转不稳的趋势。

The results of absorption spectra, KI fluorescence quenching studies, competitive binding studies and thermal denaturation experiments suggested that the interaction between AQS and DNA be intercalative.

在CT DNA存在下，KI对AQS光化学反应产物的荧光猝灭常数K〓比没有CT DNA存在情况下的要小。2.5×10〓mol/L的溴化乙锭即可将3.2×10〓mol/L的AQS从AQS与DNA的结合物中完全置换出来。

It is shown that the reaction U+CO→CUO with a long-lived intermediate complex has no threshold energy, which agrees with the potenlial surface. When the collision energy is greater than 418.4 kJ/mol, the intercharge reaction increases, until the CUO molecule will decompose into U, C, O completely, and these reactions have threshold energy.

结果表明：在碰撞能低(15kJ/mol)时可以生成长寿命络合物CUO(X^3A)，并且该络合反应是无阈能反应；碰撞能大于418.4kJ/mol后，先后出现置换产物UO和UC；随着碰撞能进一步增大，CUO分子将被完全碰散成U，C和O原子，而且反应U+CO(0， 0)→UO+C，U+CO(0， 0)→UC+O和U+CO(0， 0)→U+O+C是有阈能反应。

ResultsSeventeen patients with DVT after operation were discovered through Color Doppler ultrasonic detection, and all of the DVT occurred at the calf intermuscular vein.

方法纳入2007年2～7月48名患者51例全髋置换手术病例，术前和术后第7 d进行双下肢血管彩超检查，分析15项临床因素与术后下肢深静脉血栓的发生有无相关性。

Resultsseventeen patients with dvt after operation were discovered through color doppler ultrasonic detection, and all of the dvt occurred at the calf intermuscular vein. the incidence of the dvt in all patients was 33.3%, and 41.7% of these dvt patients were asymptomatic. logistic regression analysis indicated that patients older than 65(or=116.597), large volume of blood transfusion(or=1.01) and high level of triglycerides(or=37.249) were the risk factors for the occurrence of dvt after the tha.

结果经双下肢血管彩超检查，51例手术有17例发现dvt，全部为小腿肌间静脉血栓，dvt发生率33.3%；dvt患者中无症状者占47.1%(8/17)；多因素logistic回归分析表明：年龄≥65岁，输血总量大和血清甘油三脂水平高是全髋关节置换术后dvt发生的重要危险因素，其or值分别为：116.597、1.01和37.249(p.05)。

Range of motion of the metacarpophalangeal joint was 61.3° on average and that of the proximal interphalangeal joint 40.3°.

结论人工关节置换术是解决手部关节僵直的好方法，但要注意手术适应证的选择。

BACKGROUND: Lumbar degenerative disease has been commonly treated with nucleus pulposus extirpation or nucleus pulposus extirpation combined with internal fixation; however, with the development of non-rigidity fixation, interspinous dynamic stabilization and intervertebral disk displacement attract more and more attention.

摘要背景：在早期，腰椎间盘退变性疾病的治疗临床常用髓核摘除或髓核摘除加刚性内固定融合技术，但是随着非刚性固定技术的发展，棘突间稳定系统固定和全椎间盘置换在脊柱非融合治疗中逐渐受到人们的重视，其优点日益突出。
