沿海产盐区与非产盐区18～45岁人群碘营养状况及甲状腺功能水平研究

目的掌握厦门市沿海产盐区与非产盐区居民盐碘、18～45岁人群碘营养和甲状腺功能水平状况,为采取针对性的防治措施提供依据。方法选择沿海产盐区翔安区和非产盐区集美区为调查点,调查居民合格碘盐食用率、18～45岁育龄期妇女和男性尿碘水平、甲状腺激素水平和海带、紫菜的摄入习惯。结果产盐区和非产盐区盐碘中位数均为27.21 mg/kg,合格碘盐食用率分别为95.33%和96.33%;18～45岁男性尿碘中位数分别为206.55μg/L和232.95μg/L,尿碘<100μg/L的比例分别为20.97%和10%;18～45岁育龄期妇女尿碘中位数分别为176.95μg/L和227.70μg/L,尿碘<100μg/L的比例分别为21.67%和25%;产盐区和非产盐区18～45岁男性和育龄期妇女的甲状腺激素TSH、Tg、FT3、FT4、TPOAb、TT3、TT4中位数均在正常值范围内;产盐区18～45岁男性的甲状腺功能亢进阳性率为3.4%、育龄期妇女的甲状腺功能减退和亚临床甲状腺减退症的阳性率均为1.67%,而非产盐区均为0。产盐区和非产盐区18～45岁男性和育龄期妇女中均有一定比例易患甲状腺免疫性疾病的人群。每月食用海带、紫菜的次数≥4次、1～3次和<1次的人尿碘组间比较无统计学差异。结论产盐区和非产盐区18～45岁男性和育龄期妇女碘营养总体处于适宜状态,应坚持食盐加碘措施,对育龄期妇女在婚前体检时开展常规碘营养水平和甲状腺功能检测

Study on the iodine nutrition and thyroid function of children in salt and non-salt-producing areas in Xiamen city

目的了解厦门市沿海产盐区和非产盐区儿童碘营养状况与甲状腺功能水平,为科学补碘提供依据。方法选择产盐区翔安区和非产盐区集美区为调查点,随机抽取600名8~10岁儿童进行甲状腺检查,随机抽取部分儿童采集尿样、家中盐样和血样,检测含碘量和血清fT3、fT4、TSH、Tg、TPOAb、TT3和TT4水平。结果产盐区与非产盐区合格碘盐食用率为81.5%和98.6%;儿童甲状腺肿大率为3.0%和0.7%,尿碘中位数为202.8和238.4μg/l;两区儿童的甲状腺功能指标均在正常范围,未发现甲亢、亚甲亢及甲减患者,亚甲减患病率为普通人群水平。结论产盐区与非产盐区8~10岁儿童的碘营养水平是适宜的,应坚持食盐加碘措施,加强儿童的科学补碘工作。Objective To study the iodine nutritional status and thyroid function of children in coastal salt and non-salt-producing areas in Xiamen for scientific strategy of iodine supplement.Methods Salt and non-salt-producing areas(Xiang-an and Ji-Mei) were selected as research areas.Totally 600 children aged 8-10 were randomly selected and thyroid palpation was performed.Urine,blood sample and household salt sample were collected to detect the iodine level and blood thyroid hormone level,including FT3,FT4,TSH,Tg,TPOAb,TT3 and TT4.Results The edible rate of qualified iodinated salt of children in the two areas were 81.5%and 98.6% respectively.The goiter rates were 3.0% and 0.7%.The medians of urinary iodine were 202.8 and 238.4μg/L.Thyroid function indicators were all in normal range in two areas.No hyperthyroidism,sub-hyperthyroidism and hypothyroidism cases were found.sub-hypothyroidism rates were similar to general population.Conclusions The iodine nutrition status of aged 8-10 children are classified as appropriate.Salt iodization measures should be promoted and supplementary iodine strategy should be enhanced for children.福建省医学创新课题(No.2009-CXB-68

JUNO Sensitivity on Proton Decay p→νˉK+p\to \bar\nu K^+ Searches

The Jiangmen Underground Neutrino Observatory (JUNO) is a large liquid scintillator detector designed to explore many topics in fundamental physics. In this paper, the potential on searching for proton decay in $p\to \bar\nu K^+$ mode with JUNO is investigated.The kaon and its decay particles feature a clear three-fold coincidence signature that results in a high efficiency for identification. Moreover, the excellent energy resolution of JUNO permits to suppress the sizable background caused by other delayed signals. Based on these advantages, the detection efficiency for the proton decay via $p\to \bar\nu K^+$ is 36.9% with a background level of 0.2 events after 10 years of data taking. The estimated sensitivity based on 200 kton-years exposure is $9.6 \times 10^{33}$ years, competitive with the current best limits on the proton lifetime in this channel
