山东省聊城市居民碘营养状况调查

目的 了解山东省聊城市居民碘营养状况．提出相应的防治对策。方法 按照LQAS抽样法对聊城市4县1区8～10岁儿童甲状腺肿(甲肿)大率、尿碘含量、居民户碘盐覆盖率及合格率、饮水碘含量、儿童智商(IQ)水平及当地居民生活习惯进行了调查．并对相关指标进行了分析。结果 水碘与儿童尿碘、儿童甲肿率之间的关系出现不一致性。儿童甲肿率与尿碘、碘盐覆盖率之间的关系完全旱现一致性。结论 聊城市4县1区存在高碘性甲肿的流行，是由于居民饮用高碘水和食用碘盐共同作用的结果。据此提出了该地区高碘性甲肿的主要预防措施为停止饮用高碘水和食用碘盐。

2008年山东省碘缺乏病高危地区核实调查

Objective To survey the highly risk iodine deficiency regions of Shandong Province and to provide reference basis for further executing urgent iodine supply. Methods The annual document of cretinism in Licheng District in Jinan City and Shouguang City, the two iodine deficiency regions, were referred. Forty children aged 8-10 years of 2 targeted schools from 3 towns out of every targeted region underwent palpation, ultrasonography and As3+-Ce4+catalyzing speetrophotometry for ultra iodine examination. Twenty women aged 18-40 years from 2 villages sampled from every targeted town received ultra iodine examination and edible salt examination of iodine with direct titration. Results No new cretinism and suspected cretinism was found since 1995 in the regions. The goiter rates of children of the two regions detected with palpation and ultrasonography were 7.5% (18/241),6.2% (15/241) and 5.0% (13/259), 1.2% (3/259), respectively. Two hundred forty and 249 urine samples were respectively collected in school children, in which the median urinary iodine was 226.3,282.7 μg/L. One hundred twenty urine samples were respectively collected from the two group of women, resulting a median urinary iodine of 187.2,321.7 μg/L. Eight and 2 salt samples were free of iodine in 120 salt samples collected each region, respectively. The rate of qualified iodized salt was 100%. Conclusions It is not necessary to urgently implement iodine supply in Shouguang City and Licheng District. However, reinforcement of supervise on salt industry and eliminating the hazard from non-iodized and disqualified iodized salt remains in need.

意向性运动疗法对大鼠脑缺血再灌注损伤后GluR2和GRASP-1表达的影响

目的了解意向性运动疗法干预后对于大鼠行为学变化,观察对GluR-2以及GRASP-1的影响,揭示意向性运动疗法的可能作用机制。方法利用线栓法制备大脑中动脉栓塞模型(MCAO),再灌后24h后随机分为两大组:第一组用于TTC染色;第二组用于免疫组化,每组再分为4个小组:即大脑中动脉梗死模型组(MCAO)组、意向性运动疗法(WM)组、饲养环境改变(EM)组、一般康复(CR)组,各组大鼠再分成再灌后3d、7d、15d、30d 4个小组。结果 (1)再灌后7d、15d、30d,WM组大鼠爬梯频率次数明显多于CR组及EM组;再灌后15d、30d,WM组大鼠前肢抓握功能改善明显;再灌后30d,WM组大鼠神经缺损评分明显低于MCAO组。(2)TTC染色发现再灌后15d、30d,WM组、CR组、EM组较MCAO组梗死体积增大,以WM组增大明显,有统计学意义。(3)免疫组化结果显示在再灌后30d,WM组缺血半暗带区GluR2、GRASP-1蛋白表达明显增加,与MCAO组相比具有统计学意义。(4)相关性分析显示,大鼠脑缺血再灌注损伤后脑组织GluR2与GRASP-1的表达呈明显正相关(r=0.678,P0.01)。结论意向性运动疗法可能通过诱导大鼠脑缺血再灌注损伤后缺血半暗带区GRASP-1表达上调,增加GluR2表达,增强突触传递效能,提高突触可塑性。
