The objectives of this study were to examine the short-term effects of health education and health promotion in the control of schistosomiasis, and to monitor the long-term impact on re-infection patterns. The study was carried out in six Schistosoma japonicum-endemic villages located in the Poyang Lake area. Three different interventions were implemented,… (More)
[reaction: see text] Asymmetric Michael additions of cyclohexanone to both aryl and alkyl nitroolefins in the presence of 20 mol % of organocatalyst 2b and 10 mol % of n-butyric acid afford adducts 5 with high diastereoselectivities and enantioselectivities.
In order to explore the possibility of further optimising schistosomiasis control during the maintenance and consolidation phase in China, two highly endemic villages were selected to compare the strategy of 'passive chemotherapy' plus health education to that of mass chemotherapy singly. Emphasis was placed on treatment coverage with praziquantel among… (More)
OBJECTIVE To monitor water body infestation in schistosomiasis high-risk areas with sentinel mouse technique. METHODS A total of 72 surveillance sites from 47 counties were selected in Hunan, Hubei, Jiangxi, Anhui, Jiangsu, Yunnan, and Sichuan. The water infectivity of Schistosoma japonicum was determined in the surveillance sites by using sentinel mice… (More)
A model was developed using remote sensing and geographic information system technologies for habitat identification of Oncomelania hupensis, the intermediate host snail of Schistosoma japonicum, in the Poyang Lake area, China. In a first step, two multi-temporal Landsat TM 5 satellite images, one from the wet and the second from the dry season, were… (More)
The diagnosis of Schistosoma japonicum (Sj) infection in low prevalence areas of the People's Republic of China is challenging due to the sensitivity of the detection methods, leading to an underestimation of the disease burden. We compared the sensitivities of the miracidium hatching test (MHT) with the modified Kato-Katz method (KK) and the combination of… (More)
OBJECTIVE To understand the migration regulation, knowledge of schistosomiasis control and infection status of migrant population in mountainous regions. METHOD Migrants from history heavy endemic villages of schistosomiasis were selected by the convenience sampling method, then they were investigated by questionnaire and fecal examination. RESULTS A… (More)
This report presented the endemic status of schistosomiasis in the People's Republic of China at national level in 2014, and analyzed the data captured from the national schistosomiasis prevention and control system and 81 national schistosomiasis surveillance sites. Among the 12 provinces (municipality and autonomous region) endemic for schistosomiasis… (More)
An enantioselective formal [3+3] annulation reaction of cyclic ketones with enones has been developed. In the presence of 20 mol % of pyrrolidine-thiourea 1a or N-(pyrrolidin-2-ylmethyl)trifluoromethanesulfonamide 1i, the reactions afford bicyclo [3.3.1] adducts in moderate to good yields with good to high enantioselectivities under mild conditions.
OBJECTIVE To analyze the spatial-time distribution characteristics of schistosomiasis in Jiangling County, Hubei Province from 2006 to 2011. METHODS The surveillance data of schistosomiasis of Jiangling County from 2006 to 2011 were collected, and a spatial database was established. The spatial-time permutation cluster analysis was performed by SaTScan… (More)
