目的应用心血管磁共振(CMR)定量评价Danon病和肥厚型心肌病(HCM)患者胸廓骨骼肌(TSM)形态和组织特征,以此提供辅助鉴别诊断信息。方法回顾性收集完成CMR检查的15例Danon病患者(Danon病组),并与性别、年龄配对的15例HCM患者(HCM组)及15例健康志愿者(对照组)进行对比研究,测量所有受试者4组TSM(胸大肌、胸小肌、竖脊肌及肩胛下肌)的面积指数(TSMAi)、2组骨骼肌(胸大肌及肩胛下肌)的T1弛豫时间及细胞外容积(ECV)。采用单因素方差分析、Kruskal-Wallis检验进行三组数值的比较。结果Danon病组总TSMAi低于HCM组和对照组[(15.37±3.28)cm^(2)/m^(2)vs(23.02±3.88)cm^(2)/m^(2)vs(22.33±4.67)cm^(2)/m^(2),P0.05)。Danon病组及HCM组胸大肌native T1值均大于对照组(均P0.05)。结论应用CMR能有效评价Danon病患者TSM形态及组织特征改变。与HCM患者相比,Danon病患者TSM显著萎缩,伴细胞外容积增加。CMR为两者的鉴别诊断提供了TSM的定量参考依据。

宜202井区位于天宫堂构造,该井区受区块构造作用,断层和裂缝较发育,碳酸盐岩地层井漏频发,且茅口组发育高压,溢漏并存,同时桥堵浆粒径匹配差、水泥浆驻留能力弱,导致堵漏效果差、成功率低。文章研究了一种多功能固结承压堵漏技术,该技术中的多功能固结承压堵漏剂优选柔性纤维、刚性细颗粒和固化剂等材料,兼备架桥滤失固结和整体固结两种堵漏模式,在时间和地温的作用下稠化固结,12~24 h的初始固结体具有较高的封堵强度,通过室内评价,固结封堵强度随着时间的推移逐渐增加最高可达到19.2 MPa。在Y215井雷口坡组现场应用,承压能力当量密度提高0.36 g/cm3,复杂治理周期较同区域降低75.51%,该技术适用于密度1.40~2.00 g/cm3的各类水基钻井液,能满足40℃~150℃条件下的安全施工。

In order to develop a highly sensitive material for nondestructive testing(NDT),(Tb_(0.3) Dy_(0.7))Fe_(1.95) thin films were deposited on FeCo substrates at room temperature by magnetron sputtering and *** magnetostrictive properties and the detection efficiency of the composite films were *** demonstrate that the detection efficiency roughly shows regular consistency with the magnetostrictive strain of the TbDyFe films. Heat treatment has a great effect on the crystalline state and the magnetostrictive strain of the composite materials. The as-deposited(Tb_(0.3) Dy_(0.7))Fe_(1.95) films are amorphous, and the saturation magnetostriction(ls) is only 90 ppm. However, the nanostructured crystalline REFe2 is partially separated out in amorphous matrix after annealing at 600C for 1 h, and the ls increases to 265 ppm. Simultaneously, the detection efficiency of the composite materials is obviously improved compared to that of the as-deposited films. The detection signal of traditional FeCo strip is0.4 V at the excitation power of 1.0 P and frequency of 128 kHz and that of the strip increases significantly by depositing one layer of(Tb_(0.3) Dy_(0.7))Fe_(1.95) film. The detection signal of the composite material annealed at 600C is the best, even reaching saturation value of 2.5 V(1.0 P, 128 kHz). The results may provide us with a method for preparing new materials for NDT.
