OBJECTIVE To evaluate the effect of comprehensive measures on the control of schistosomiasis in an aquaculture zone, so as to provide the evidence for formulating the schistosomiasis control strategy in special environments. METHODS From 2003 to 2012, the comprehensive control measures including individual prevention, detection and treatment of schistosomiasis patients, environmental modification, and health education were implemented in an aquaculture zone of Luyang Lake, Jiangdu District of Yangzhou City, Jiangsu Province. The changes in human morbidity of schistosomiasis and the status of Oncomelania snails were investigated annually. RESULTS No acute infection of Schistosoma japonicum was detected for successive 10 years, and only 5 cases of chronic infection were found in the latest 5 years in the aquaculture zone. Since 2007, no snail habitats were found. CONCLUSIONS The comprehensive control measures are effective.

SCL-90 was used for a survey of 1072 college students with a random questionnaire in order to understand the college students' psychological status.The result indicates,generally speaking,college students' psychology have some problems.College students are higher than national norm in obsessive compulsive and phobia in which there are significant differences(t=7.203,P 0.01).Anxiety and depression have the biggest influence on college students' psychological health in 9 factors of SCL-90(r=14.250,r=13.191).This shows that college students' overall psychological health condition is worthy of being paid great attention to.

Objective: To explore the relationship between the life satisfaction and mental health of medical college students in northern Jiangsu.Methods:553 college students were tested with Life Satisfaction Index B and SCL-90.Results: There were no obvious differences between medical and non-medical college students,but medical college students' forced,interpersonal sensitivity was higher than that of non-medical college students'(t=1.141,3.041),psychophobiapsychophobia psychophobiapsychophobiattterror and psychotic were lower than that of non-medical college students'(t=-4.893,-2.416.Significantly SCL-90 factors and the life satisfaction index were negatively correlated(P<0.01).Conclusion: The mental health of the students is closely related to the life satisfaction index.

Key stream generator is a core part of Stream cipher.In accordance with structural thought of nonlinear combination key stream generator,a new RSA-LFSR key stream generator is proposed in this paper.The random sequences from the generator generated in combining of RSA and LFSR algorithm make combining operations with evolving Boolean function based on gene expression programming (GEP),and output key stream.Meanwhile,safety inspections are made to the different length key sequences generated through RSA-LFSR key stream generator.Through runs test,frequency inspection, sequential test and the calculation of linear complexity,the experiments demonstrate that RSA-LFSR key stream generator is more superiority and security than traditional nonlinear combination key generator.

Effects of liquid si-deposition treatment on the structure,acidity and cokeability of catalyst were investigated by XRD,NH3-TPD and TGA.Catalytic performance and stability of the treated and untreated catalysts were respectively evaluated in a fixed bed reactor.The results showed that the structure of catalyst had little change after the liguid si-deposition treatment whereas the treatment led to the decrease of catalyst acidity,especially the proportion of the stong acid sites.The zeolites treated by liquid si-deposition had an improvement in both the catalytic performance and reaction stability.The result indicated that too many stong acid sites on the catalyst would cause severe coking and decrease the catalyst stability and liquid si-deposition treatment can remove the external acid sites.
