【摘要】：目的比较三门峡市克山病病区儿童与非病区儿童发硒含量差异,为克山病防治提供实证数据。方法 2015年选择三门峡市灵宝市、卢氏县2个县(市)的克山病病区作为监测点,同时选择义马市和湖滨区非病区作为对照点,分别采集6~12岁儿童发样,进行发硒含量测定。样品采用湿消化法处理,使用氢化物发生-原子荧光光谱法进行测定。结果三门峡市克山病病区共收集儿童发样100份,非病区儿童发样100份。灵宝市、卢氏县2个县(市)克山病病区的儿童发硒含量分别为[(0.22±0.07)、(0.22土0.03)],低于非病区的义马市和湖滨区儿童发硒含量[(0.30±0.08)、(0.38土0.13)mg/kg]。比较各采样点儿童发硒最大值与最小值发现,病区儿童发硒范围相对较窄(0.03~0.41mg/kg),最小值、最大值均低于非病区(0.11~0.51mg/kg)。有50.3%(151/300)的儿童发硒含量0.25 mg/kg,处于硒营养缺乏状态。结论三门峡市克山病病区儿童硒营养水平整体偏低,补硒还需长期坚持和多样化。
[Abstract]:Objective to compare the difference of hair selenium content between children in Keshan disease area and non-endemic area in Sanmenxia city, and to provide empirical data for prevention and control of Keshan disease. Methods in 2015, Lingbao City, Sanmenxia City and Keshan Disease area in two counties (cities) of Lushi County were selected as monitoring points. The hair samples of 612 year old children were collected and the hair selenium content was determined. The samples were treated by wet digestion and determined by hydride generation-atomic fluorescence spectrometry. Results 100 hair samples were collected from Keshan disease area of Sanmenxia city and 100 hair samples were collected from non-endemic areas. The hair selenium content of children in Keshan disease areas of Lingbao and Lushi counties was (0.22 卤0.07), (卤0.22 卤0.03), which was lower than that of children in Yima city and lakeside area [(0.30 卤0.08)]. (0.38 卤0.13) mg/kg]. By comparing the maximum and minimum values of hair selenium in different sampling points, it was found that the range of hair selenium of children in the disease area was relatively narrow (0.03~0.41mg/kg), the minimum value and the maximum value were lower than those in the non-endemic area (0.11~0.51mg/kg). The hair selenium content of 50.3% (151 / 300) children was in selenium deficiency state. Conclusion the selenium nutrition level of children in Sanmenxia Keshan disease area is on the low side, and selenium supplementation should be persisted and diversified for a long time.
