Usher综合征患者血清离子浓度的变化

目的探讨Usher综合征(Usher syndrome,USH)患者血清离子浓度的变化情况。方法选取2015年9月至2018年9月北京同仁医院眼科中心的46例临床诊断为USH患者作为USH组;同时选取同期于北京同仁医院体检中心体检的90例正常人为对照组。检测各组受试者血清离子浓度。将USH组与对照组的各血清离子浓度进行比较。结果 USH组患者血清钙离子浓度为(2.364±0.101)mmol·L-1,高于对照组的血清钙离子浓度(2.304±0.082)mmol·L-1,差异有统计学意义(P=0.000);USH组患者钾离子浓度为(4.124±0.360)mmol·L-1,高于对照组的钾离子浓度(3.965±0.288)mmol·L-1,差异有统计学意义(P=0.006);两组间的钠离子、氯离子、无机磷离子浓度相比,差异均无统计学意义(均为P>0.05)。结论 USH患者的钙离子与钾离子浓度异常,这种异常可能与其发病有关。

STUDIES ON SYNTHESIS AND CHARACTER OF INORGANIC ION EXCHANGER TITANIUM PHOSPHATE-AMMONIUM TUNGSTOPHOSPHATE

In this paper, a new complex inorganic ion exchanger Titanium Phosphate - Ammonium Tungstophosphate (abbreviated as TiP - AWP) was synthesized, whose exchange character and chemical structure were studied, Thiscompound exhibits high exchange capacity and selectivity for Cs+, its exchangecapacity attains 0. 95 mmol/g in the medium of 0. 1 mol/L HNO3, andwhich almost doesn’ t change in the 1 AW imitated waste solution. There areno change in exchange capacity and structure after several times of exchanging,eluting, regenerating, which is of great importance to the separation and uptaking of radio - nuclides. Further more, this exchanger has good thermal andradioactive stability.
