Totally 60 semi-circular bending specimens cored from superpave gyratory compactor with three groups of notch depths are tested at the temperature of-10 and 20℃ The experimental results reveal good repeatability in EAM characterization. The tensile strength ratio of SCB to the indirect tensile test is at a range of 1.4 to 1.7, and the ultimate strength of EAM is exponentially dependent on the notch depths. At the test temperatures, the critical J-integral value of EAM is much higher than that of hot mix asphalt with thermoplastic asphalt binder. The response mode of EAM changes from ductile mode to brittle mode and the fracture energy increases 30% when temperature decreases from 20 to-10℃, while its critical J-integral value decreases only 15%.

The results were expressed in mean±1SD. Pearson X~2 test and One-way ANOVA test were used. The data analyzed using the SPSS (version 11.5). Results: The sensitivity, specificity, positive and negative value of US for the LPEH model on the children cadaver were 88%, 84%, 79%, 91%, respectively. With regard to the thickness of femora head cartilage, the thickness of the anterior layer or posterior layer, there were no significant differences among three groups. However, the anterior layer was thicker than the posterior layer in three groups. The fluid in hip joint was detected in all of 21 symptomatic hips, which was clear commonly (90%) in early procedure. The amount of fluid in anterior recess showed a positive correlation with age (p .05). No fluid was detected in the asymptomatic and normal hips (2mm). The mean maximum width of inferomedial recess was significantly larger than that of anterior recess (12.50±4.04mm vs.4.35±0.8mm, p 0.05) in the symptomatic hip joints. The echogenic entrapped labral plicaes were demonstrated in the inferomedial recess in all of 21 children with LPEH, whose length and width ranged from 5.3mm-25.0mm (mean,15.6±5.6mm) and from 4.0mm-17.0mm (mean,8.9±7.8mm).
结果1,尸体LPEH髋关节模型的超声诊断敏感性、特异性分别为88%、84%,阳性预测值、阴性预测值分别为79%、91%。2,21例患儿的LPEH患髋(21侧)、健髋(21侧),以及21例正常儿童健髋(42侧)的超声检查显示:髋关节周围软组织及股骨头无形态结构差别;股骨头软骨厚度无统计学差异(3.5±0.5mm vs.3.6±0.4mm vs.3.6±0.5mm,p>0.05);关节囊前层及后层厚度无统计学差异(前层厚度2.79±0.74 mm vs.2.56±0.40mm vs.2.56±0.72mm;后层厚度2.70±0.82mm vs.2.48±0.54mm vs.2.44±0.58mm,p>0.05),但LPEH患髋关节囊前、后层均较后二组有增厚趋势。3,LPEH患髋均存在关节腔内积液,且早期较为清晰;积液以髋关节内下间隙明显,内下间隙较前间隙明显增宽(12.50±4.04mm vs.4.35±0.8mm,p<0.05),其内见嵌顿滑膜唇皱襞呈稍强回声的占位性团块,长约15.6±5.6mm,宽约8.9±7.8mm,90.5%(19/21)嵌顿皱襞内未见血流信号。4,所有LPEH患髋治疗后超声复诊均显示正常。
