[Study on rapid recognition technique of schistosome susceptibility water body I Animal skin making and effect assessment].

Objective: To develop a bionic animal skin and evaluate its detective effect of cercariae so as to provide a new technique for the monitoring of the schistosome susceptibility water body.

Methods: A bionic animal skin was made with pigskin and the experiments were carried out for evaluating its detective effects of cercariae in laboratory and simulate fields, and at the same time, the sentinel mouse method was used as the control.

Results: In the laboratory, the cercariae were found in 10-, 30-, 60-cercaria subgroups in the bionic animal skin group after 1 and 2 hours, but the cercariae were found only in the 60-cercaria subgroup in the sentinel mouse group.

Methods: The knowledge, attitude and values on schistosomiasis control of 523 chronic schistosomiasis patients in Nanchang County, Jinxian County and Xinjian District in the Poyang Lake District were investigated with questionnaires. And the accuracy rates of the knowledge, attitude and practice among the patient groups of different counties, genders, age groups, occupations and educational levels were analyzed.

[Investigation on human infections in Nanchang City in 2014].

Objective: To investigate the endemic situation of human infection in Nanchang City in 2014 and analyze the influencing factors, so as to provide the evidence for control measures.

Methods: The high-risk population of infection in Nanchang City was collected as an experiment group, and a control group was settled with the ratio of 1∶1. The serum tests and epidemiology surveys were conducted simultaneously, and the influencing factors were analyzed.

[Effect of schistosomiasis control in towns reached criteria of infection controlled in Nanchang City].

Objective: To evaluate the effect of schistosomiasis control in towns that had reached the criteria of infection controlled in Nanchang City.

Methods: The residents and livestock of 14 towns that had reached the criteria of infection controlled in Nanchang, Xinjian and Jinxian counties of Nanchang City were sampled to investigate the schistosomiasis endemic situation, Oncomelania hupensis snail status, and data of schistosomiasis control work.

Results: The positive rate of serum tests of the residents was 2.

[Epidemic situation of acute schistosomiasis in Nanchang City of Jiangxi Province from 2005 to 2012].

Objective: To understand the endemic regulation of acute schistosomiasis in Nanchang City of Jiangxi Province from 2005 to 2012 so as to provide the reference for policy-making of schistosomiasis control.

Methods: The data of acute schistosomiasis were collected and analyzed with the descriptive epidemiology method in Nanchang City from 2005 to 2012.

Results: A total of 52 acute schistosomiasis cases were reported in Nanchang City from 2005 to 2012.

[Current status of human Schistosoma japonicum infection and reinfection in marshland and lake regions of Xinjian County, Jiangxi Province, China].

Objective: To understand the dynamics of human infection and reinfection of Schistosoma japonicum after chemotherapy in marshland and lake endemic regions so as to provide the evidence for developing a cost-effective control strategy.

Methods: From 2007 to 2011, the schistosome infection, intensities and reinfection of population were investigated and the results were analyzed dynamically in Caohui Village, a national schistosomiasis surveillance site in Changyi Township, Xinjian County, Jiangxi Province, China.

Results: The schistosome infection rate was 3.

[Effect of niclosamide spreading oil on killing schistosome cercariae].

Dechlorinated water (100 ml, 30 degrees C) was put into a plate (diameter 15 cm), and 1% niclosamide spreading oil 5 microl was added, then a ring of Schistosoma japonicum cercariae were picked up to the plate. The time of killing all the cercariae was observed at three time points (immediately, 24, 48 h), and the dechlorinated water was used as control. The results showed that schistosome cercariae were all killed in three minutes by 1% niclosamide spreading oil at the three time points.

[Influencing factors of changes of Oncomelania snail densities in Poyang Lake region, Nanchang City, 2011].

Objective: To explore the influencing factors of the significant decrease of snail densities in Poyang Lake region, Nanchang City, 2011.

Methods: According to the elevation of the environment, 5 grasslands where there were high snail densities and their elevations were from 14 to 17 m were selected as study areas. The data of snails in the past three years and the hydrological information in the past five years were collected and analyzed.

[Study on an intervention model of "schools without infected students with schistosoma japonica" in heavy endemic areas].

Objective: To study an intervention model of "schools without infected students with schistosoma japonica", to control and prevent students from schistosoma infection.

Methods: Twelve primary schools of four heavy endemic counties (districts) with schistosomiasis in the Poyang Lake areas were selected as the study fields, of which, ten schools were the experimental groups, and the other two schools were the control groups by cluster random sampling. All enrolment students were the target population.

[Establishment and application of school-based health promotion and intervention model of schistosomiasis in lake-type endemic area].

Objective: To establish an intervention model of school health promotion, and apply it in developing "schistosomiasis-free schools".

Methods: At the pilot stage, all students of Henghu primary school and Banshan primary school in Xinjian County of Jiangxi Province were selected as experiment group and control group, respectively. A baseline survey covered knowledge and attitude on schistosomiasis control, water contact behaviors and Schistosoma japonicum infection rate.

[The second stage larvae of Ascaris lumbricoides].

Objective: To induce the apoptosis of human alveolar epithelial cells (A549) by the extraction of the second stage larvae of Ascaris lumbricoides and investigate the extraction concentration and inducing time related to the apoptosis.

Methods: Following to the results of Microculture Tetrazolium Test (MTT), five concentrations of the extraction of the second stage larvae were chosen to induce the apoptosis of A549 cells. Meanwhile, control groups without the inducement were set up.
