得了流感怎么办?奥司他韦(特敏福)、扎那米韦(瑞乐沙)等抗病毒药物能缓解流感症状,并帮助你提前1-2天恢复健康.但数月以来,奥司他韦因缺乏疗效而被批评. 6月,联合国世界卫生组织基本药物目录删除了奥司他韦.“联合国世界卫生组织做出删除决定的原因是奥司他韦在临床试验及临床使用中疗效均很低.一些专家怀疑,导致疗效低的原因可能是由于很多人是在感冒症状出现了1-2天后才开始服药的.

Six villages were selected for study in conjunction with provincial surveillance and control efforts in schistosomiasis-endemic areas.An indirect hemagglutination assay(IHA) was used to detect Schistosoma japonicum infection in residents ages 6 to 65 years in six villages in schistosomiasis-endemic areas.Schistosomiasis leakage and control was considerable in six villages.Leakage was detected at a rate of 42.67% and leakage was controlled at a rate of 17.73%.Leakage was most often detected as a result of working outside the province,accounting for 97.09% of leaks detected.Sickness or pregnancy were the second most frequent reason leaks were detected,accounting for 2.91% of leaks detected.Leakage control was most often the result of sickness or pregnancy,accounting for 76.55% of leaks controlled.Leakage control was also the result of refused treatment,accounting for 23.45% of leaks controlled.Misuse of praziquantel was also somewhat common.Measures to control schistosomiasis should be adjusted in line with social changes and economic restructuring of villages.Health education should be increased and the timing of schistosomiasis detection and control should be adjusted.Tracking of individuals responsible for schistosomiasis leakage should be enhanced,and the standard use of praziquantel should be emphasized.

Objective To study the effects of schistosomiasis control by means of standardized and safe use of praziquantel.Methods Three villages in schistosome-endemic areas were selected as study sites.Strategies for standardized and safe use of chemotherapy,such as selecting appropriate times for treatment each year,treating the disease with medication,and tailoring strategies to different patients,were studied.Results Three years after measures for standardized and safe use of chemotherapy were carried out in the three affected villages,chemotherapy coverage increased from 77.45% to 99.79%,the infection rate among residents decreased from 3.16% to 2.08%,and side effects of praziquantel decreased from 10.65% to 0.63%.Conclusion The standardized and safe use of praziquantel in affected areas is a new measure to help control sources of infection,improve the quality and coverage of chemotherapy,and reduce the infection rate among residents and adverse reactions to praziquantel.

晚期血吸虫病(简称晚血)是由于反复或重度感染血吸虫尾蚴,未经及时治疗或有效的杀虫治疗,经过较长时间的病理发展过程,造成虫卵沉积、组织纤维化形成而引起相应器官功能受损及障碍的一种重型血吸虫病.湖北省由于地域地形的复杂性,居民接触疫水的频繁性,使得该省晚血病人救治工作的任务十分繁重.晚血患者患病后部分丧失或全部丧失劳动力,大多难以继续从事生产劳动,重者危及生命而严重影响家庭经济,使因病致贫现象严重[1].为了解晚血救治项目开展以来的实施效果,进一步做好晚血病人的救治工作,在每年进行的救治核查工作的基础上,对湖北省的江陵、沙市、荆州区及钟祥四县市2004～2008年间的晚血救治工作的基本情况进行了调查和分析.

湖北省是血吸虫病流行最为严重的省份之一,病牛数占全国流行省之首[1].前几年,由于受洪涝灾害等因素的影响,局部地区疫情有所回升[2].疫区大批耕牛感染血吸虫,不仅给畜牧生产造成重大损失,而且病牛是血吸虫病流行最重要的传染源[3].

杀虫丁是国内研制的新型农用杀虫剂,初步研究发现有较好的杀螺效果[3,4].为了进一步验证杀虫丁的杀螺效果,综合评价药物特性,为选用经济有效的灭螺药物提供参考依据,作者对杀虫丁与氯硝柳胺的杀螺效果进行了平行比较研究,结果报告如下.
