| 1 | Changes of PTH, 1,25(OH)_2D_3 and Biochemistry in Renal Osteodystrophy.显示文摘The changes of plasma PTH, 1,25(OH)2D3, serum calcium, phosphorus and AKP were observed in 55 uremic patients with renal osteodystrophy. The results showed that: in all types of renal osteodystrophy, plasma PTH were markedly higher than normal (P<0.001), while plasma 1,25(OHH)2D3 and serum calcium were lower than normal (P<0.001). In low bone-turnover uremic osteodystrophy (LTO), plasma phosphorus was markedly lower than that of high bone-turnover uremic osteodystrophy (HTO) and mixe d uremic osteodystrophy (MO) (P<0.05), and plasma 1,25(OH)2D3 was significantly lower than that of HTO (P<0.05). In HTO and MO, serum phosphorus was much higher than mormal (P<0.001). Plasma PTH had a negative linear correlation with plasma 1,25(OH)2D3 (P<0.05), a positive linear correlation with serum AKP (P<0.05), but no linear correlation with the duration of hemodialysis, serum calcium, serum aluminum and bone aluminum content. Plasma 1.25(OH)2D3 had no linear correlation with the duration of hemodialysis, | Jia Jing-kang, et al. Renal Unit, 2ndHospital, Zhejiang Med Uni, Hangzhou 310009.

| 7 | 基于联合代数重建技术的介观荧光分子层析成像显示文摘针对介观荧光分子层析成像重建问题,提出了一种基于联合代数重建技术的介观荧光分子层析成像重建方法。首先应用主成分分析算法对敏感矩阵进行双重降维操作,以消除敏感矩阵中的冗余信息;其次为保持重建结果与目标数据的一致性,对降维后的矩阵进行零填充;最后应用荧光光强测量数据和填充后的敏感矩阵,经带有总变差正则化项的联合代数重建技术重建组织中荧光探针的三维分布。为了评估所提方法的性能,设计了计算机数值仿体实验和血管树实验。实验结果表明,文中所提方法既提高了算法的重建精度和抗噪声性能又缩短了重建时间。因此,文中所提方法适用于介观荧光分子层析成像重建研究。 | 杨福刚 陈洋 Denzel Faulkner Xavier Intes | 2021 | 光电子.激光2021，32，2： | 1 |
