[Surveillance of schistosome antibodies in population in mountainous schistosomiasis endemic regions in China].

Objective: To understand the dynamics of schistosome antibodies in population in mountainous schistosomiasis low endemic regions, China, so as to provide the evaluation reference for immunodiagnosis.

Methods: The people who consecutively received the indirect heamagglutination assay (IHA) for schistosomiasis and Kato-Katz technique were enrolled in this study in Guixiang Village, Danling County, Sichuan Province from 2006 to 2011. The positive rates for schistosome antibodies, antibody titers and eggs per gram (EPG) were analyzed.

[Effect of comprehensive control pattern on soil-transmitted nematodiasis in Danling County].

The comprehensive control pattern centering on health education, deworming and improving drinking water and lavatories was adopted to control soil-transmitted nematodiasis in Danling County, Sichuan Province from 2007-2009. In 2009, the infection rate of soil-transmitted nematodes decreased from 57.12% of the baseline survey in 2006 to 10.

[Effect of ecological civilized homestead construction on schistosomiasis control].

Objective: To evaluate the effect of Ecological Civilized Homestead Construction on schistosomiasis control.

Methods: The data of ecological civilized homestead construction and schistosomiasis control were collected and analyzed in Meiwan Village, Shuangqiao Town, Danling County, Sichuan Province from 2004 to 2010.

Results: Ecological Civilized Homestead Construction was carried out from 2004 to 2010.

[Evaluation on effectiveness of comprehensive control model for soil-transmitted nematodiasis].

Objective: To evaluate the effect of a comprehensive control model for soil-transmitted nematodiasis.

Methods: Danling County was selected as a demonstration county carrying out the comprehensive prevention model centering on health education, nematode deworming, and drinking water and lavatories changing. On the other side, Hejiang was selected as a control.

[The immunogenicity and safety of 10 microg recombination yeast hepatitis B vaccine applied in expanded population].

Objective: To assess the feasibility of the 10 microg recombination yeast hepatitis B vaccine in the expanded applicable population group aged 5 - 18.

Methods: People with both HBsAg and anti-HBs negative were selected to take two-stage clinical experiment and the safety and immunogenicity were observed. Safety observation was conducted in 925 subjects, while 568 for immunogenicity.
