辽宁省碘缺乏病病区不同补碘时期出生儿童智力水平调查

objecfive To know and compare the intelligence level of children born in different time periods in regions with iodine deficiency disorders(IDD)in Liaoning province.Methods All 7-14 year-old children from ten schools were chosen as the subjects respectively from six villages in each of the six counties and in regions with iodine deficiency,who were respectively born at the initialization of iodinated salt supplying period(1978-1980);non-iodinated salt supplying period(1981-1990);recovery of supplied iodized salt period(1991-1995);universal iodized salt period(1996-2000),respectively.Intelligence quotient(IQ)was measured by Combined Ravens Test in China(CRT-C)and Combined Ravens Test-the Rural,in China,2nd edition(CRT-RC2).Results IQ of children during the non-iodized salt period(91.9±14.3)was significantly lower than the initial supply of iodized salt period(95.8±14.6,q=8.60,P<0.01),recovery of supplied iodized salt period(99.7±14.7)was significantly higher than the initial supply of iodized salt period, non-iodized salt sales period(q = 9.53, 18.13, all P < 0.01 ),universal salt iodization( 104.3 ± 14.9) was significantly higher than the initial supply of iodized salt period, non-iodized salt sales period, recovery of supplied salt iodization(q = 20.00,28.00,10.46, all P < 0.01). Children's rate of mental retardation (IQ≤69) was higher in non-iodinated salt supplying period (6.7%, 88/1314 ) than the initial supply of iodized salt (4.4%, 21/471, χ2 = 3.85, P < 0.05), recovery of supplied iodized salt period(3.3%,48/1470) was significantly lower than non-iodinzed salt supplying period (χ2 = 15.37, P < 0.01), universal salt iodization period(2.7%, 36/1344) was lower than the initial supply of iodized salt period(χ2 = 4.41, P < 0.05) and non-iodinzed salt supplying period(χ2 = 26.34, P < 0.01 ). The IQ and intelligent retarded rates in children born during the initial years of iodinated salt supplying period were not different. The IQ of the children during ten years of non-iodized salt supplying period fluctuated in a "∪" curve, while the intelligent retardation rates in a "∩" curve.The children born during the period of recovery supplied iodized salt increased their IQ and lowered the retardation rates year after year. The IQ of the children in universal iodized salt period kept on increasing while intelligent retarded rates reduced to the lowest level. Conclusions The intelligence level of children born in regions with IDD during non-iodized salt supplying period is remarkably lower than that of the beginning years of iodinated salt supplying period. The intelligence level of children born after universal iodized salt period is remarkably higher than that of the initial iodinated salt supplying period and recovery of supplied iodized salt period, respectively.     

石家庄市碘盐质量与重点人群尿碘水平调查结果

Objective To assess the quality of iodized salt and investigate the urinary iodine level of pupils and women after implementation of universal salt iodization in Shijiazhuang city. Methods Between 2004 and 2008, nine salt samples were randomly collected from wholesale enterprises of 5 different directions of east,south, west, north and center in Shijiazhuang city every month. Meanwhile, eight salt samples, four urine samples of women, were randomly collected in each of the 8 households of 210 villages selected from 23 counties. Between 2004 and 2008, twenty urine samples of 8 - 10 year old pupils were collected in each of 160 schools from the 23 counties. Direct titration method was used for salt iodine determination, iodine concentration in urine was detected by the method of ammonium persulfate digestion-As3+-Ce4 + catalytic spectrophotometry. Results At wholesale level, the qualified rate of iodized salt was above 99%. At household level, the consuming rate of iodized salt was above 95%, and the rate of consuming non-iodized salt was less than 5%. The rate of qualified iodized salt was above 90% in every year except 2004(87.10%), and the rate of consuming qualified iodized salt was above 90% in those years except 2004(83.08%). Urinary median iodine level of both the pupils and the women was higher than 100 μg/L, and the rate of urinary iodine level that less than 50 μg/L was below 10%. Conclusions The quality assessment of iodized salt from wholesale companies and related indices of urinary iodine level of pupils, women and household iodized salt have already reached the national standard for eliminating iodine deficiency disorders.

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.

大黄素诱导急性胰腺炎胰腺细胞凋亡机制的实验研究

目的 从凋亡信号传导的角度探讨中药大黄素治疗大鼠急性胰腺炎的分子生物学机制。方法 将44只雄性Wistar大鼠随机分为正常组，非治疗组，大黄素组，以腹腔注射雨蛙肽物方法诱导大鼠急性胰腺炎模型。并于大黄素治疗后6，24，48，72，96小时处死大鼠。应用HE染色比较胰腺组织病理学改变，应用Tunel法检测胰腺细胞凋亡指数，应用RT-PCR技术检测治疗前后凋亡调控基因Bak和BaxmRNA表达。结果 大黄素干预治疗急性胰腺炎后96小时淀粉酶值显低于未治疗组，胰腺细胞凋亡指数显高于未治疗组，凋亡调控基因BakmRNA的表达与未治疗组之间无显性差异。而BaxmRNA的表达显高于未治疗组。结论 大黄素治疗实验性急性胰腺炎的机制可能与干预凋亡调控基因有关。诱导凋亡调控基因Bax表达增强可能是干预凋亡信号传导的重要机制，而与Bak基因表达无关。     

Use of Gaming in Self-Management of Diabetes in Teens

With the growing prevalence of diabetes in teens and frequent concomitant problems with adherence, adolescents are a frequent target for diabetes self-management support and education. Due to widespread use of technology among teens in general, the use of serious games, games used for purposes beyond entertainment with the intention to educate and support health behavior for teens with diabetes self-management, is an emerging and promising practice. This report explores games intended for teens with diabetes, how the use of games may enhance clinical practice, and provides suggestions for future research and better utilization of these technologies. Current research on the use of gaming for promoting diabetes management in teens is fairly limited, with some initial support for improvements in both behavioral and clinical outcomes among teens. More research is clearly needed in order to further determine how gaming can best be utilized to impact health outcomes in these teens, as well as potential mechanisms of change.
