制造业工人肌肉骨骼疾患发生模式及影响因素

目的 探讨制造业工人工作相关肌肉骨骼疾患(work-related musculoskeletal disorders,WMSDs)在多个部位的发生模式及其影响因素。方法 应用肌肉骨骼疾患调查问卷对4家制造企业工人的WMSDs患病情况及影响因素展开流行病学调查。WMSDs病例定义为过去一年内身体颈部、肩部、肘部、手腕/手、上背部、下背部、臀/大腿、膝部、踝/足9个部位中一个或多个部位出现疼痛、麻木、不适或活动受限等症状,持续时间超过24 h,经休息后症状仍未完全缓解,且排除外伤、残疾、其他急症或后遗症等。各部位WMSDs患病情况间的关联度用log-binomial模型计算出的现患比(PR值)评估,采用多分类Logistic回归模型分析WMSDs主要患病部位中多个部位共患病的影响因素。结果 制造业工人WMSDs总患病率达79.7%,主要患病部位为下背部、颈部、肩部和上背部,患病率依次为62.3%、55.7%、45.6%和38.7%。这4个部位患病情况间的PR值较高,4个部位共患病率为25.2%,3~4个部位共患病率为41.4%。多分类Lgistic回归分析提示,颈部、肩部、上背部和下背部中3~4个部位患WMSDs的影响因素涉及多个方面,其中女性(OR=2.86,95%CI 2.38~3.33)、工龄15~19年者(OR=1.87,95%CI 1.49~2.34)患病风险较高;颈部经常长时间或频繁前倾(OR=2.15,95%CI 1.86~2.48)、颈部经常长时间或频繁扭转(OR=1.64,95%CI 1.40~1.92)和经常大幅转身(OR=1.40,95%CI 1.20~1.64)等生物力学因素可能为疾患发生的危险因素;每天做相同的工作(OR=1.73,95%CI 1.44~2.08)、员工短缺(OR=1.50,95%CI 1.31~1.71)和经常加班(OR=1.38,95%CI 1.20~1.60)等组织管理因素可能增加疾患的发生风险;经常长时间站着工作(OR=0.77,95%CI 0.65~0.91)和感觉工间休息时间充足(OR=0.51,95%CI 0.44~0.59)等因素为保护性因素。结论 本研究中制造业工人颈部、肩部、上背部和下背部WMSDs患病率高,4个部位的患病情况间关联密切,其3~4部位共患病率较高,提示在制造业工人中可能存在“颈-肩-上背-下背”多个部位患病的WMSDs发生模式,这种模式的主要影响因素包括个体因素、生物力学因素和组织管理因素几个方面。     

Dynamic photoacoustic imaging of neurovascular coupling in salivary glands

The purpose of this study was to apply photoacoustic imaging (PAI), a relatively new imaging method, to non-invasively map neurovascular dynamics in salivary glands. Dynamic PAI with co-registered ultrasound (US) was performed in mice to monitor salivary gland hemodynamics in response to exogenous muscarinic receptor stimulation (pilocarpine) and blockade (atropine). Pilocarpine increased salivary gland oxygen saturation (%sO₂) within minutes after administration, which was abrogated by atropine. A significant correlation was observed between change in %sO₂ measured by PAI and saliva secretion. PAI is a novel imaging method that can be used for functional assessment of neurovascular dynamics in salivary glands.     

基于“绿色设计”理念的中药制药膜分离工艺选择原则与方法

面向绿色制造的中药制药工艺路线设计,亦称"绿色设计",其目的是极小化产品全生命周期过程的资源消耗和环境影响,协调优化经济效益和环境效益。以膜技术为核心的制药分离工艺技术与药物绿色制造息息相关,"环境、性能和成本"三大要求和成熟度、分离技术原理是制药分离工艺绿色设计的基本要素,"清洁工艺"可降低原料及能源耗损,切合"预防优于治理"的理念,也可提高企业的经济效益,对生态保护和经济建设的和谐发展具有重要保障作用。以构建膜与树脂技术系统集成为例,介绍中药制药工艺绿色设计具体实施方案,对中药制药分离工艺设计的技术经济问题开展分析和讨论。     

现代中药产业发展的金融支持研究

金融支持是影响中药产业快速发展的关键因素。由于企业规模小、信息不对称、经营风险高、财产抵押难等方面原因,我国中药产业发展面临着较强的资金约束。在深入分析中药企业研发、创业孵化、初创、加速成长、稳定等阶段融资特征的基础上,提出了充分利用银行信贷、信用担保、创新基金、风险投资、上市融资等方式为中药产业发展提供金融支持。     

African media coverage of tobacco industry corporate social responsibility initiatives

Guidelines for implementing the World Health Organization's Framework Convention on Tobacco Control (FCTC) recommend prohibiting tobacco industry corporate social responsibility (CSR) initiatives, but few African countries have done so. We examined African media coverage of tobacco industry CSR initiatives to understand whether and how such initiatives were presented to the public and policymakers. We searched two online media databases (Lexis Nexis and Access World News) for all news items published from 1998 to 2013, coding retrieved items through a collaborative, iterative process. We analysed the volume, type, provenance, slant and content of coverage, including the presence of tobacco control or tobacco interest themes. We found 288 news items; most were news stories published in print newspapers. The majority of news stories relied solely on tobacco industry representatives as news sources, and portrayed tobacco industry CSR positively. When public health voices and tobacco control themes were included, news items were less likely to have a positive slant. This suggests that there is a foundation on which to build media advocacy efforts. Drawing links between implementing the FCTC and prohibiting or curtailing tobacco industry CSR programmes may result in more public dialogue in the media about the negative impacts of tobacco company CSR initiatives.     

Alcohol industry involvement in science: A systematic review of the perspectives of the alcohol research community

Issues

Alcohol companies have recently invested large sums of money in answering research questions to which they have clear vested interests in the outcomes. There have been extensive concerns about corporate influence on public health sciences, following the experience with the tobacco industry.

Approach

This systematic review aims to investigate the perspectives of researchers on the activities of alcohol industry actors in relation to science, in order to guide future research. All data published in peer‐reviewed journals (including commentaries, opinion pieces, editorials and letters as well as research reports) were eligible for inclusion. This analysis focuses on the manifest rather than latent content of the articulated views, and accordingly adopts a thematic analysis using an inductive approach to the generation of themes.

Key Findings

There are serious concerns identified in three main areas, principally defined by where the impacts of industry scientific activities occur; on evidence informed policy making (instrumental uses of research by industry actors), on the content of the scientific evidence base itself (industry funding as a source of bias); and on the processes of undertaking research (transgressions of basic scientific norms). There are also opposing views which provide a useful critique. The evidence‐base on the validity of all concerns has been slow to develop.

Implications

The concerns are extensive, longstanding and unresolved and high quality investigations are needed.

Conclusion

This study informs the detailed content of the research needed to address the concerns identified here.

     

A retrospective public health analysis of the Republic of Ireland's Food Harvest 2020 strategy: absence,avoidance and business as usual

The concept of an Ecological Approach to health and including Health in All Policies warrants inter-sectoral and transdisciplinary collaboration to improve health determinants and reduce health inequities. Agriculture policies, which greatly influence food production and its environmental impacts as well as food availability and dietary consumption, are therefore of interest to public health. Increasing rates of non-communicable diseases linked to diets containing high levels of processed foods, increasing numbers of households unable to access nutritious food and the environmental consequences of the food system are amongst the major health challenges of today, both globally and in Ireland. In 2010, Ireland’s Department of Agriculture, Food and Fisheries published Food Harvest 2020 a roadmap for Irish agriculture for the subsequent decade prepared against a backdrop of rising diet-related ill-health and increasing environmental concerns. This article critically analyses the process of consultation and stakeholder involvement in the development of Food Harvest 2020 from a public health perspective. Publically available documents including submissions to the Food Harvest 2020 consultation process were the primary source of data. This study highlights a distinct absence of public health representation in the process, an avoidance of some key public health challenges and the dominance of a ‘business as usual’ approach.

煤矿开采行业工人下背痛与职业应激关联探讨

目的探讨煤矿开采行业工人下背痛与职业应激的关联性。方法2015年1月至2016年12月,选择山西省某大型煤矿开采企业某矿区的一线生产工人472名作为研究对象,采用问卷调查方法调查其基本信息、下背痛患病信息、职业应激水平,二分类Logistic回归法分析下背痛与职业应激的关系。结果研究对象472人中186人在过去一年内发生过下背痛,下背痛年患病率为39.41%。下背痛组的职业应激任务得分高于非下背痛组,差异有统计学意义(P<0.01)。二分类Logistic回归分析结果显示:年龄、婚姻情况、工龄、职业应激任务、劳动强度、工作中保持同一姿势、倒班可能是下背痛的危险因素(P<0.01),吸烟可能是下背痛的保护因素(P<0.01)。结论职业应激任务可能是煤矿开采工人发生下背痛的危险因素(P<0.01),合理分配工作任务、及时疏解煤矿开采工人的职业应激,可能是预防和控制下背痛的有效途径之一。
