Early warning of marine organism invasion is an effective method to prevent unit blockage of nuclear power stations and protect the normal operation of nuclear power stations. In this study, an early warning model for marine organism invasion in water intake of nuclear power stations was established. The density of marine organisms and size and direction of ocean current were considered. The method of fitting and interpolating existing data was used to determine early warning threshold and model parameters. Results showed that invasion intensity values and warning levels can be depicted effectively by the early warning model on the basis of marine organism density and the relative speed of ocean current.

第37届中国控制会议

Consider the density of marine organism and the size and direction of the current, an early warning model of marine organism invasion based on BP neural network was established. A quantitative evaluation of the intensity of marine organism invasion can be obtained through the established early warning model. BPNN is used to estimate the relationship between marine organisms density and invasion intensity in different current velocity. And then determine the warning threshold and establish an invasion model. The results show that the early warning model can be effectively described on the invasion intensity and the warning level.

第三十九届中国控制会议

In order to improve the accuracy and efficiency of early warning of marine organism invasion in nuclear power plant cold source system, a multi-information fusion model based on dynamic fuzzy neural network is proposed to deal with the problems of single-index evaluation, arbitrary decision-making and incorrect combination of information in the traditional analysis and processing. Taking the intake of Daya Bay Nuclear Power Plant as the research object, the early warning information sources were screened from five aspects: marine organism density, ocean current, sea breeze, sea water temperature and sea water salinity. Aiming at the non-linearity and uncertainty of the early warning system, a dynamic fuzzy neural network model based on Gauss membership function, T-norm product operator, error reduction rate pruning strategy and linear least squares method is designed. And then early warning system based on multi-source information fusion and dynamic fuzzy neural network method is obtained. Based on this model, the possibility of water intake blockage in nuclear power plant can be predicted. The experimental data verify that the learning error and generalization error of the proposed prediction algorithm are controlled within [-0.1, 0.1], and the Euclidean distance is 10-5 orders of magnitude.

Trace metal(Cr, Ni, Cu, Zn, Cd and Pb) exposures, distribution and bioaccumulation were investigated in marine organisms from Guangdong coastal regions, South China. The results showed that all of the selected metals were observed in marine organisms with a predomination of Cu and Zn. The metal exposure levels exhibited obvious variations between species with the decreasing order of crab > shellfish > shrimp > fish. The higher metals enrichment seen in shellfish and crab species primarily attributed to their living habits and the higher sediment background values of trace metals. Endpoint bioaccumulation factor(BAFfd) was used to characterize the bioaccumulation potentials of marine organisms to trace metals, of which Cu and Zn were the most accumulated elements. The exposure of trace metals in the cultured organisms was far lower than those in wild marine organisms, which is probably due to the effect of growth dilution. Comparisons with previous studies demonstrated that the concentration profiles of most trace metals declined over the last one to two decades, except Cu, that increased indistinctively.

Chinese Journal of Natural Medicines 2015年第3期13卷 192-198页

Thais luteostoma has been utilized as a crude drug whose shell and soft tissue have been widely used for the treatment of heat syndrome in China for thousands of years. The present study was designed to investigate the antipyretic and anti-inflammatory activities of T. luteostoma. T. luteostoma was divided into shell （TLSH） and soft tissue （TLST） samples in the present study. The rat model of yeast-induced fever was used to investigate their antipyretic effects; and the rat model of hind paw edema induced by carrageenan was utilized to study their anti-inflammatory activities, and at the same time, the concentration variations of the central neurotransmitter [prostaglandin E2 （PGE2） and cyclic adenosine monophosphate （cAMP）], inflammatory mediators [tumor necrosis factor （TNFα）, interleukin-1β （IL-1）, interleukin-2 （IL-2） and interleukin-6 （IL-6）] and ion （Na^＋ and Ca^2＋） were also tested. The results showed that TLSH and TLST extracts significantly inhibited yeast-induced pyrexia in rats （P 〈 0.05）, and exhibited more lasting effects as compared to aspirin, and TLSH had the better antipyretic activity than TLST, and that TLSH and TLST could significantly prevent against carrageenan induced paw edema in rats （P 〈 0.05）; and markedly reduced levels of PGE2, cAMP, TNFα, IL-1β, IL-2, IL-6, and Na^＋/Ca^2＋. In fever model, TLST could significantly reduce the levels of PGE2 （P 〈 0.01） in rats＇ homogenate and TNF a （P 〈 0.05）, IL-113 （P 〈 0.01） in the plasma than TLSH, whereas TLSH could reduce the content of IL-2 （P 〈 0.01） and IL-6 （P 〈 0.01） in plasma and increase the content of Ca2＋（P 〈 0.01） in plasma and homogenate more significantly than TLST. In conclusion, T. luteostoma extract has antipyretie and anti-inflammatory activities, which may be mediated through the suppression of production of PGE2, cAMP, Na^＋/Ca^2＋ , TNF a, IL-1β, IL-2, and IL-6.
