金融危机爆发使人们再次清晰认识到房价波动对一个国家系统性金融风险所产生的重要影响,传统价格稳定型的货币政策并不能单独实现金融稳定,因此宏观审慎监管政策开始广泛被各国监管部门实施。然而,货币政策与宏观审慎政策在不同的经济条件下如何协调配合并实现最优组合目标是政策制定者亟待解决的重要问题。在我国房价高涨的背景下,本文通过建立DSGE模型研究了在面对不同外生冲击时不同货币政策规则与宏观审慎政策的配合策略。研究结果表明:在住房需求冲击下,盯住房价的货币政策与宏观审慎政策相互配合,能够有效抑制房价上涨,较好地熨平经济波动;在技术冲击与货币政策冲击下,采用单一目标的货币政策规则并辅之以宏观审慎政策时政策实施持续性较高,可以很好地缓解房价波动,有效降低系统性金融风险,实现宏观经济稳定。

Atrial fibrillation （AF） is one of the most common .arrhythmias in clinical practice. AF results in electrophysiological alterations which involve increased atrial effective refractory period and atrial effective refractory period dispersion, reduced rate adaptation of atrial effective refractory period, and slowed atrial conduction. These variances promote their own maintenance-AF begets AF.1 Previous study suggested that Ca^2＋ overload and metabolic derangement contributed to electrophysiological remodeling in AF. However, we did not demonstrate a persistent disturbance in energy metabolism during AF in our previous study,

Background Several studies suggest that cyclooxygenase-2 （COX-2） contributes to the delayed progression of ischemic brain damage. This study was designed to investigate whether COX-2 inhibition with parecoxib reduces focal cerebral ischemia/eperfusion injury in rats. Methods Ninety male Sprague-Dawley rats were randomly assigned to three groups： the sham group, ischemia/reperfusion （I/R） group and parecoxib group. The parecoxib group received 4 mg/kg of parecoxib intravenously via the vena dorsalis penis 15 minutes before ischemia and again at 12 hours after ischemia. The neurological deficit scores （NDSs） were evaluated at 24 and 72 hours after reperfusion. The rats then were euthanized. Brains were removed and processed for hematoxylin and eosin staining, Nissl staining, and measurements of high mobility group Box 1 protein （HMGB1） and tumor necrosis factor-α （TNF-α） levels. Infarct volume was assessed with 2,3,5-triphenyltetrazolium chloride （TTC） staining. Results The rats in the I/R group had lower NDSs （P 〈0.05）, larger infarct volume （P 〈0.05）, lower HMGB1 levels （P 〈0.05）, and higher TNF-α levels （P 〈0.05） compared with those in the sham group. Parecoxib administration significantly improved NDSs, reduced infarct volume, and decreased HMGB1 and TNF-α levels （P 〈0.05）. Conclusions Pretreatment with intravenous parecoxib was neuroprotective. Its effects may be associated with the attenuation of inflammatory reaction and the inhibition of inflammatory mediators.

[ Objective] The aim was to improve the saccharification of wheat bran cellulose. [ Method] Taking the wheat bran as raw materials, and using orthogonal method, the effects of acid concentration, temperature, times and substrate concentration on the saccharification were investigated. [ Result] The influence of temperature on the acid treatment of the sacchadfication of wheat bran cellulose was significant. Influences of acid concentration on the hydrolysis were distinct. Influences of time and substrate concentration were insignificant. The optimal pretreatment conditions were 1.5% of sulfuric acid concentration and 0. 067 g/ml of substrate concentration at 100℃ in three hours. Under this condition, the sugar concentration was 38.137 mg/ml, and the hydrolysis rate reached 51.485%. [ Conclusion] The study improved the saccharification of wheat bran cellulose, which provided theoretical basis for the application of wheat bran industrial process.

乡村振兴战略的部署实施为农村基础设施建设、农村经济结构创新、农村技术人才培养提供了充分的政策保障,极大地改善了农村电商发展的外部环境与内在要求。与此同时,农村电商的发展又在市场拓展、产业升级、资金融通等方面促进了乡村振兴战略的实施。为了实现二者的高效互动,本文通过构建农村电商与乡村振兴互动发展的系统动力学模型,揭示了农村电商网商数量、农特产品市场、农村电商专业人才规模、资金规模4个子系统之间的因果关系和动态反馈机制,并基于我国2010—2016年农村经济发展的相关统计数据对农村电商和乡村振兴的互动性进行了仿真模拟。对系统动力学模型进行的稳定性和有效性检验表明,模型能够真实地反映农村经济增长过程中农村电商和乡村振兴互动发展的实际系统结构和功能。在此基础上,通过调整农村电商固定资产投资水平参数、农村电商教育投资水平参数、农业财政补贴因子、农村居民消费补贴因子4个政策变量的取值,进一步对农村电商同乡村振兴互动发展的政策进行模拟。模拟结果显示:影响农村电商与乡村振兴互动发展的主要因素是农业财政补贴力度;相关扶持政策在农村电商和乡村振兴互动发展的过程中具有不同的政策效果,呈现出明显的阶段性特征。因此,逐步加大农业财政补贴力度,构建全方位的政策支持体系对于实现农村电商与乡村振兴的互动发展至关重要,同时应根据农村电商发展与乡村振兴战略实施的现状,分阶段、有针对性地重点推进相关政策,以促进农村电商与乡村振兴的互动发展。

本文首先构建了中国金融系统脆弱性指标体系并采用因子分析法对金融系统脆弱性指数进行趋势分析,然后利用马尔可夫区制转换模型对其进行区制状态分析,从而识别出金融系统脆弱性状态的变化。实证结果表明,在样本研究区间内中国金融系统脆弱性整体呈现上升趋势且波动幅度较大,但在2014年以后,脆弱性指数有所回落且处于可控范围内;中国在"低脆弱性"区制的时间要少于"高脆弱性"区制的时间,且向"高脆弱性"区制转移的概率较高,金融体系容易产生脆弱性集聚的风险。因此,中国需要将以前粗放式的金融增长转变为注重质量和效率的高效金融增长,完善金融机构风险控制和风险指标体系,加大对金融产品、组织和制度的监管力度。
