This study aimed to assess taste acuity in pediatric cancer patients after treatment completion. Seventy-three patients who had completed cancer treatment (median age, 13 years;range, 7 - 18 years) and had not received any further treatment for at least 6 months were enrolled. Eighty-one healthy children (median age, 10 years;range, 8 - 19 years) served as controls. We determined the thresholds for four tastes (sweet, salty, sour, and bitter) using the filter-paper disc method. There was no significant difference in the thresholds of taste acuity for the four test solutions between the patient and control groups. The duration since treatment completion (<5 years vs. ≥5 years) had no significant impact on taste acuity for the four test solutions. The threshold for tasting salt was significantly higher in the group that had received chemotherapy + radiation and/or hematopoietic stem cell transplantation than that in the group that had received chemotherapy-only. Our results indicated that taste acuity after treatment completion in pediatric cancer patients was the same as that in healthy children. However, some treatment modalities were correlated with an impaired ability to taste salt. Gustatory test results should be considered while deciding nutritional support modalities after treatment completion in pediatric cancer patients.展开更多
为获取盐渍土蒸发过程中总吸力、基质吸力及渗透吸力的大小,阐明不同水盐条件下各吸力动态变化特征及其对蒸发的影响,将冷镜露点水势仪(WP4C)和并行接触式滤纸法相结合,对不同含盐量土壤蒸发过程中总吸力、基质吸力与渗透吸力的动态过...为获取盐渍土蒸发过程中总吸力、基质吸力及渗透吸力的大小,阐明不同水盐条件下各吸力动态变化特征及其对蒸发的影响,将冷镜露点水势仪(WP4C)和并行接触式滤纸法相结合,对不同含盐量土壤蒸发过程中总吸力、基质吸力与渗透吸力的动态过程及其对土壤蒸发的影响进行了分析;选取4种常用土壤水分特征曲线模型,利用SWRC-Fit对基质吸力与含水量之间的关系进行了拟合。结果表明:盐渍土在蒸发过程中基质吸力与渗透吸力占总吸力的比例不断发生变化,相同含水率下渗透吸力占比始终大于基质吸力;含水率与盐分均会影响土壤渗透吸力的大小,其中盐分的影响更显著。土壤蒸发.强度及持续时间均会受到土壤盐分影响。通过WP4C与并行接触式滤纸法可以同时获取蒸发过程中非饱和土壤的总吸力、基质吸力与渗透吸力,Fredlund and Xing(FX)模型能够较好地拟合实验蒸发过程中的实测数据,在蒸发各阶段均有较好拟合精度,也进一步证明了实验方法与数据的可靠性。展开更多
