探讨鞋内压力监测技术在糖尿病足患者护理中的研究进展,明确鞋内压力监测技术在护理应用中的利弊以及发展前景。通过系统检索2000年1月—2022年3月Web of Science、PubMed、中国知网、万方和维普数据库,获得鞋内压力监测技术在糖尿病足护理中应用的相关文献,并追溯纳入研究的参考文献。然后采用QUADAS-2工具对纳入的文献进行质量评估,以评价纳入文献的偏倚风险和适用性。共纳入15篇文献,包括12篇期刊论文和3篇论文集。文献质量评估中患者选择、评价试验、参考标准以及流程和进展的偏倚低风险分别显示为53%、73%、47%和73%;患者选择、评价试验和参考标准的适用性高风险都显示为73%。总结出鞋内压力监测技术领域的传感器技术和鞋内“安全”压力阈值设定的特征指标在护理应用中的作用。结果表明,用于DF患者的鞋内足底压力监测系统需进一步改进可靠性和有效性测试以及临床验证,为后续开发用于监测和预警DF患者足底压力的鞋内压力测试系统的研究提供依据。

随着人民币汇率双向波动的逐步频繁,中国各经济部门所面临的外汇风险暴露逐渐增大,基于这一现实,本文运用非线性自回归分布滞后(NARDL)模型,选取2005年7月—2017年7月的数据,动态分析了中国上市公司行业层面的外汇风险暴露情况,结果表明:中国所有行业均存在显著的长期或者短期外汇风险暴露,且外汇风险暴露程度较大,所有行业的公司都应该强化外汇风险意识,并构建防范外汇风险的系统;外汇风险暴露存在时滞性和J曲线特性,央行的外汇干预可能在短期内不起作用或者引起相反的效果,建议中国央行仅在人民币汇率长期偏离均衡水平从而影响资源的合理配置时才进行外汇干预;外汇风险暴露存在短期和长期的非对称性,无论是短期还是长期,人民币贬值冲击相对于升值冲击会影响更多的行业,人民币的长期升值趋势并不会对较多行业产生不利影响,中国应更多关注人民币汇率贬值所带来的风险;根据非对称外汇风险暴露的行业特征,中国可以通过实现产业结构的多元化来大大减缓外汇风险对中国经济的冲击,而国内投资者可以通过构建各行业的股票组合以实现外汇风险的对冲。

运用自回归分布滞后模型,选取2005年7月至2018年7月的数据研究了中国的外汇风险暴露情况。结果表明:中国公司短期外汇风险暴露的显著比例高于长期外汇风险暴露的显著比例,且存在显著的J曲线效应,总体上短期受益于人民币贬值,而长期受益于人民币升值;行业层面中,6个行业存在显著的短期或长期外汇风险暴露,并且短期和长期特征区别显著。因此,要有效地应对中国公司的外汇风险暴露问题,中国公司和金融机构可根据外汇风险暴露的短期和长期特征进行针对性的风险管理。此外,央行应该逐步退出常态化外汇干预,不必过于放大汇率波动对实体经济的短期影响,更重要的是维持人民币的长期升值趋势。
