Urinary iodine, salt iodine, and thyroid volume(TVOL) were determined. Questionnaires were used to investigate dining places and iodine-rich processed foods. The water iodine was from the2017 national survey. Multi-factor regression analysis was used to find correlations between *** Children ate 78.7% of their meals at home, 15.1% at school canteens, and 6.1% at other *** percentage of daily iodine intake from water, iodized salt, iodine-rich processed foods, and cooked food were 1.0%, 79.2%, 1.5%, and 18.4%, respectively. The salt iodine was correlated with the urinary iodine and TVOL, respectively(r = 0.999 and-0.997, P < 0.05). The iodine intake in processed foods was weakly correlated with the TVOL(r = 0.080, P < 0.01). Non-iodized salt used in processed foods or diets when eating out had less effect on children’s iodine nutrition *** Iodized salt remains the primary source of daily iodine intake of SAC, and processed food has less effect on iodine nutrition. Therefore, for children, iodized salt should be a compulsory supplement in their routine diet.

Abstract Foodborne disease is one of the most important public health issues worldwide. China faces various and unprecedented challenges in all aspects of the food chain. Data from laboratory-based foodborne disease surveillance systems from 2013 to 2016, as well as different regions and ages, can be found along with differences in the patterns of pathogens detected with diverse characteristics. Vibrioparahaemolyticus has been the leading cause of infectious diarrhea in China, especially among adults in coastal regions. Salmonella has been a serious and widely distributed pathogen responsible for substantial socioeconomic burden. Shigella was mostly identified in Northwest China and the inland province （Henan） with less-developed regions among children under 5 years. Data from foodborne disease outbreak reporting system from 2011 to 2016 showed that poisonous animals and plant factors responsible for most deaths were poisonous mushrooms （54.7%） in remote districts in southwest regions. The biological hazard that caused most cases reported （42.3%） was attributed to V. parahaemolyticus, the leading cause of foodborne outbreaks. In this review, we summarize the recent monitoring approach to foodborne diseases in China and compare the results with those in developed countries.

Alignment of Nanoscale Single-Walled Carbon Nanotubes Strands

引用

Nano-Micro Letters 2011年第3期3卷 146-152页

作者： Danna Yang Lin Wang Xiaoxian Zhang Dongwei Wang Zhiqiang Shen Sai Li School of Chemical Engineering Sichuan University Academy of Military Medical sciences Chinese PLA Center for Disease Control & Prevention

Depositing single-walled carbon nanotubes(SWNTs) with controllable density, pattern and orientation on electrodes presents a challenge in today's research. Here, we report a novel solvent evaporation method to align SWNTs in patterns having nanoscale width and micronscale length. SWNTs suspension has been introduced dropwise onto photoresist resin microchannels; and the capillary force can stretch and align SWNTs into strands with nanoscale width in the microchannels. Then these narrow and long aligned SWNTs patterns were successfully transferred to a pair of gold electrodes with different gaps to fabricate carbon nanotube field-effect transistor(CNTFET). Moreover, the electrical performance of the CNTFET show that the SWNTs strands can bridge different gaps and fabricate good electrical performance CNTFET with ON/OFF ratio around 106. This result suggests a promising and simple strategy for assembling well-aligned SWNTs into CNTFET device with good electrical performance.
