Similar to species immigration or exotic species invasion,infectious disease transmis-sion is strengthened due to the globalization of human activities. Using schistosomiasis as an exam-ple,we propose a conceptual model simulating the spatio-temporal dynamics of infectious diseases. We base the model on the knowledge of the interrelationship among the source,media,and the hosts of the disease. With the endemics data of schistosomiasis in Xichang,China,we demonstrate that the conceptual model is feasible; we introduce how remote sensing and geographic information systems techniques can be used in support of spatio-temporal modeling; we compare the different effects caused to the entire population when selecting different groups of people for schistosomiasis control. Our work illustrates the importance of such a modeling tool in supporting spatial decisions. Our mod-eling method can be directly applied to such infectious diseases as the plague,lyme disease,and hemorrhagic fever with renal syndrome. The application of remote sensing and geographic informa-tion systems can shed light on the modeling of other infectious disease and invasive species studies.

Because the physical and chemical properties of nanosized materials mostly differ from the existing microsized materials, their potential impacts on human health and the envi-ronment will be topics under the serious discussions in press and in a number of international scientific journals. We analyze and summarize the existing data of the experimental study on the biological activities and adverse effects of nanoscale materials/particles including single wall carbon nanotubes, multi wall carbon nanotubes, titanium oxide and iron powders. Though some biological behaviors of nanoscale materials observed cannot be understood on the basis of the current knowledge, as the existing data are mostly preliminary, it is too early to make some ex-clusive conclusions on biological activities (or the toxicity) of any of nanoscale materials. The experimental techniques, the current topics, and the future research directions for this new re-search field are also discussed.

The dose-dependent cytotoxicity effect on human hepatocyte（HL-7702 cells） induced by ＂naked＂ Fe3.4 nanoparticles was assessed through cell viabilities and lactate dehydrogenase（LDH） activities. Three important oxi dative indexes of the cells by glutathione peroxidase（GSH-Px）, superoxide dismutase（SOD） and malondialde hyde（MDA） were determined. The good correlation of the cell viabilities with their GSH-Px, SOD and MDA levels indicated that the cytotoxicity is related to activation of oxidative stress induced by Fe3.4 nanoparticles. The oxida tive stress also leads to corresponding DNA damage in a similar dose-dependent manner, followed by the changes of cell cycle and cell apoptosis. Such work provides important experimental data for the safety evaluation of superpa ramagnetic Fe3.4 nanoparticles.

In the 1960s and 1970 s, attention was focused on rapid population growth and large scale family planning programs were launched in many developing countries. However, the paradigm for understanding fertility decline assumed that exogenous socioeconomic changes were necessary to reduce family size. By the mid-1990s, the standard model of the demographic transition had been all but discarded, partly there were numerous country experiences inconsistent with the model. The 1994 International Conference on Population and Development （ICPD） emphasized women＇s broader needs, which were important but were promoted by reducing attention to population and the need for family planning. The timing of this shift was peculiar, because the cairo proponents were depending on an already discredited model of reproductive behavior. The policy shift at cairo undermined the political coalition that had supported international family planning since the 1960s. As a result of declining financial support, the health of women has deteriorated seriously in the past decade. Meantime, the countries that have been successful in lifting unprecedented numbers of people out of abject poverty were acting independently of the cairo consensus.

Objective To evaluate the impact of long-term air particulate matter exposure on the life expectancy and survival rate of Shanghai residents. Methods Epidemiology - based exposure-response function was used for the calculation of attributable deaths to air particulate matter in Shanghai, and the effect of long-term exposure to particulate matter on life expectancy and survival rate was estimated using the life table of Shanghai residents in 1999. Results It was shown that in 1999, the long-term air particulate matter exposure caused 1.3.-1.69 years reduction of life expectancy and a decrease of survival rate for each age group of Shanghai residents. Conclusion The effect of long-term exposure to air particulate matter on life expectancy is substantial in Shanghai.
