禽流感防控综合管理平台的设计与实现

当前禽流感防控形势日趋严峻,在禽流感防控管理方式落后的情况下,为了适应禽流感防疫工作需要,设计并实现了县市级禽流感防控综合管理平台。该管理平台集禽流感免疫、检疫、监督、监控于一体,并自动生成报告。为防疫应急指挥提供辅助管理和决策参考,并且通过快速追踪病源,及时采取应对措施。     

Institutional shaping of research priorities: A case study on avian influenza

Since outbreaks in 2003, avian influenza has received a considerable amount of funding and become a controversial science policy issue in various respects. Like in many other global and multidisciplinary societal problems fraught with high levels of uncertainty, a variety of perspectives have emerged over how to “tackle” avian influenza and public voices have expressed concern over how research funds are being allocated. In this article, we document if and how research agendas are being informed by public policy debates. We use qualitative and quantitative approaches to examine the relations between expectations of outcomes of public science and the existing research landscape. Interviews with a cross-section of stakeholders reveal a wide range of perspectives and values associated with the nature and objectives of existing research avenues. We find that the landscape of public avian influenza research is not directly driven by expectations of societal outcomes. Instead, it is shaped by three institutional drivers: pharmaceutical industry priorities, publishing and public research funding pressures, and the mandates of science-based policy or public health organizations. These insights suggest that, in research prioritization, funding agencies should embrace a broad perspective of research governance that explicitly considers underlying institutional drivers. Deliberative approaches in public priority setting might help to make agendas more plural and diverse and thus more responsive to the contested and uncertain nature of avian influenza research.     

鸡场禽流感的诊断

本实验对某鸡场鸡群中出现的一种以呼吸道症状和产蛋下降为主要特征的疫情进行了临床症状和流行病学调查,对病死鸡进行了解剖检查并从病鸡病料中分离到一种病毒,通过血凝(HA)和血凝抑制(HI)试验、病毒中和试验(VNT)和琼脂免疫扩散试验(AGP)等方法对该病毒进行了签字。结果表明该次疫情为A型流感病毒感染。

Improvement of the efficacy of influenza vaccination （H5N1） in chicken by using extract of Cochinchina momordica seed （ECMS）

Seeds of a Chinese traditional medicine plant, Cochinchina momordica were used in the present study for the improvement of influenza vaccine （HSN 1） in chicken. Crude extraction from Cochinchina momordica seed （ECMS） was obtained by ethanol extraction method. In experiment No. 1, two weeks old chickens were immunized with influenza vaccine （HSN1） alone or combined with ECMS （5, 10, 20, 40 and 80 μg/dose）. Serum IgG antibody levels （by ELISA） as well as effects on dally weight gain were measured on 0, 7, 14 and 28th day after immunization. Results revealed that all ECMS groups numerically increased the antibody levels while 10 and 20 μg/dose groups significantly （P〈0.05） enhanced total IgG antibody on day 28, when compared with control. Average daily weight gain was also significantly higher in 20 μg/dose ECMS group. Adjuvant effect was also confirmed in experiment No. 2 when chickens were immunized with 20 μg/dose ECMS and antibody titer was measured through hemagglutination inhibition （HI）. It is concluded that ECMS has potential to improve the immune responses and deserve further study as an adjuvant.

经济欠发达地区禽流感防控现状与措施建议

由于H5N1高致病性禽流感给全球养禽业乃至人类生命安全造成了重大威胁,世界动物卫生组织将其列为对人类和动物健康具重大威胁的疾病。然而,当前不少农村等经济欠发达地区人禽混养现象、禽类产品卫生监督的不完善及落后的医疗卫生水平对整个禽流感的防控极其不利,同时也严重威胁到广大人民群众的生命安全。着重加强上述地区畜禽防疫管理和基层卫生防疫工作是当前全社会所共同关注的问题。
