Objective To explore a high molluscicidal efficient method in special Oncomelania hupensis snail environments. Methods In 2005 and 2006,in large special environments(rubble creek beaches and seepage barren hills with snails),the me-chanical soil-buried method(excavator digging to bury deep snails)and manual soil-buried method were used respectively,and the results were compared for the cost-effectiveness. Results With the mechanical soil-buried method in 2006,the investment was 0.78 yuan/m2,and the compression rate of snail areas was 100%;with the manual soil-buried method in 2005,the investment was 1.34 yuan/m2,and the compression rate of snail areas was 20.26%. The former was much better than the latter. Conclusion In the large special environments with snails,the mechanical soil-buried method is superior to manual soil-buried method.

Objective To evaluate the molluscicidal effect of black plastic film combined with carbon amide. Methods In Jiangdong Town Jinhua City the field with Oncomelania hupensis in the history was selected as experimental area and divided into 3 groups Group One was administered with black plastic film combined with carbon amide Group Two was administered with simple black plastic film and Group Three was a control group. Results On the 3rd 7th 15th 20th and 30th day after the experiment the mortality rates of O. hupensis of Group One were 86.0% 88.0% 100% 100%and 100%respectively which were significantly higher than those of the control group all P<0.05 . The differences of mortality rates between Group One and Group Two were statistically significant on the 3rd and 7th day after the experiment Group One was superior to Group Two . Conclusion The black plastic film combined with carbon amide can improve the molluscicidal effect.

This paper presented the practice of performance evaluation at public hospitals in Wuhu.The performance evaluation system at public hospitals should emphasize public benefits,present a true picture of work and management performance,and help build the incentive and constraint mechanism.In addition,it should encourage public hospitals to strengthen management,improve quality of care and control health care costs.The system is designed for providing a safe,effective,convenient and inexpensive medical and health services for the people.

Objective: To investigate the association between sleep with emotional and behavioral problems of preschool children in Wuhu City. Methods: A cluster sampling survey was conducted among senior class of 12 kindergartens in Wuhu City, a total of 1 158 preschool children were investigated. The self designed questionnaire was used to investigate the general situation and sleep characteristics. Strengths and Difficulties Questionnaire (SDQ) and Sleeping Quality Questionnaire for Children Aged 2-5 years were used to investigate their emotional behavior and sleep disorders. Results: About 44.21% of respondents had emotional and behavioral problems, among which peer interaction was the most prominent. There were gender differences in sleeping alone and the need of comforters for sleep. 41.97% of preschool children detected at least one type of sleep disorder, and the detection rate of disturbed sleep was 33.83% in girls, which was higher than that of boys(25.97%). Abnormal sleep and disturbed sleep increased the risk of emotional and behavioral problems in preschool girls( OR=2.33, 95%CI =1.25-4.34; OR=4.92, 95%CI =1.28-19.00), adequate sleep reduced the risk( OR=0.46, 95%CI =0.27-0.77). Abnormal sleep increased the risk of boys emotional and behavioral abnormalities( OR=1.86, 95%CI =1.08-3.19), while sleeping alone reduced the risk( OR=0.59, 95%CI =0.37-0.95). Conclusion Sleep behaviors are associated with the occurrence of emotional and behavioral problems in preschool children in a sex specific manner.

In order to explore the feasibility of planting sweet sorghum in sugarcane growing area to prolong milling duration for bioethanol production, 15 varieties were sown monthly from March to September in Liuzhou of Central Guangxi Zhuang Autonomous Region. Yields of fresh stem, grain and leave were documented. The results showed that all varieties grew well when sown from March to August, but could not get mature when sown after late September. The high fresh stem yields were observed for the varieties Sart and PT3-S, 79.28 t/hm2 and 78.58 t/hm2 for single growing season, and 157.95 t/hm2 and 155.25 t/hm2 for two growing seasons. Ripening began from the end of June to late December, making the feed stock available for ethanol production from July to the end of December, even January next year.
