目的:观察CT引导下背根神经节阻滞治疗带状疱疹后神经痛(postherpetic neuralgia,PHN)的临床疗效及对血清IL-6的影响。方法:选择PHN患者40例,按照随机数字表法分为对照组和治疗组(n=20)。对照组采用CT引导下安慰剂注射及药物治疗;治疗组采用CT引导下背根神经节阻滞及药物治疗。观察治疗前1天、治疗后1天、1周、4周、8周、24周的疼痛视觉模拟评分(visual analogue scale,VAS)、加巴喷丁及曲马多的用药量及血清IL-6水平。结果:治疗后两组VAS评分、口服药物量及血清IL-6水平逐渐降低;治疗组治疗后VAS评分、口服药物量及IL-6水平较对照组显著下降(P<0.05);血清IL-6水平与VAS评分显著相关(P<0.05)。结论:CT引导下背根神经节阻滞能有效缓解PHN患者的疼痛,并能明显降低血清IL-6的水平。

We investigate the vortex dynamics in two typical hole doped iron based superconductors CaKFe_4As_4(CaK1144) and Ba_(0.6)K_(0.4)Fe_2As_2(BaK122) with similar superconducting transition temperatures. It is found that the magnetization hysteresis loop exhibits a clear second peak effect in BaK122 in wide temperature region while it is absent in CaK1144. However, a second peak effect of critical current density versus temperature is observed in CaK1144, which is however absent in BaK122. The different behaviors of second peak effect in BaK122 and CaK1144 may suggest distinct origins of vortex pinning in different systems. Magnetization and its relaxation have also been measured by using dynamical and conventional relaxation methods for both systems. Analysis and comparison of the two distinct systems show that the vortex pinning is stronger and the critical current density is higher in BaK122 system. It is found that the Maley's method can be used and thus the activation energy can be determined in BaK122 by using the time dependent magnetization in wide temperature region, but this is not applicable in CaK1144 *** we present the different regimes with distinct vortex dynamics in the field-temperature diagram for the two systems.

容积视频捕获(Volumetric Video)是通过光学扫描来捕捉拍摄对象并生成动静两态4D数字影像模型的前沿机器视觉技术之一。与现有的虚拟数字人不同,它生成的数字克隆人是对真人一比一的真实呈现,故而数字克隆人所具有的视觉情感与叙事场景于受众而言具有更深刻的沉浸性。本文从数字克隆人的生成逻辑、技术特性出发,深挖其背后生发的感知体验与情感投射,通过跨媒介叙事分析,结合实验室成果探索其沉浸意境与实践意义,揭示数字克隆人在经历“生产—创造”的过程后将客观形态和主观感性融合在一起,冲破了人与技术、人与审美、人与群体的边界,在虚拟世界中转化为现实的仿真。

本文在前期研究基础上,在南方亚热带山地对MTCLIM模型的温度估算方法进行了验证和订正。研究结果表明:经过露点订正后该研究区域内逐日水汽压的估算结果普遍改善,但在不同站点不同年份间的表现不同。对各站点共5097个观测数据计算后发现,用最低温估计的水汽压和用露点方程订正后的露点估计的水汽压与实测值之间的MAE分别为0.221kPa和0.207kPa,两种方法的模拟结果均与实测值非常接近,但后者偏差更小。与最低温度法估计的结果相比,露点订正方法能较好地模拟干旱天气条件下水汽压的变化状况。

以已有的数据、理论和模型为基础,在南方亚热带山地对MTCLIM模型的温度估算方法进行了验证和订正。结果表明:当研究区域内平均气温的正弦加权系数TEMCF为-0 15时,用日最高气温和最低气温的正弦加权平均方法对逐日平均气温的估计偏差最小。数学平均法和正弦加权平均法估计的逐日平均气温的平均绝对误差MAE分别为1 22℃和0 77℃,后者优于前者。
