Persephin, together with glial cell line-derived neurotrophic factor and neurturin, has a neurotrophic effect and promotes the survival of motor neurons cultured in vitro. In this study, dopaminergic neurons in the substantia nigra of rats were transfected with the Persephin gene. One week later 6-hydroxydopamine was injected into the anterior medial bundle to establish a Parkinson＇s disease model in the rats. Results found that the number of dopaminergic neurons in the substantia nigra increased, tyrosine hydroxylase expression was upregulated and concentrations of dopamine and its metabolites in corpus striatum were increased after pretreatment with Persephin gene. In addition, the rotating effect of the induced Parkinson＇s disease rats was much less in the group pretreated with the Persephin gene. Persephin has a neuroprotective effect on the 6-hydroxydopamine-induced Parkinson＇s disease through protecting dopaminergic neurons.

基于常规的铅芯橡胶支座模型,提出一种考虑轴向效应的新模型.该模型可以实现单向模型与双向模型之间的相互转化.通过对该模型在三向简谐荷载作用下的响应分析,探讨了铅芯橡胶支座考虑轴向效应时的力学性能.结果表明:双向模型的恢复力-位移曲线与单轴时有较大差别;轴向荷载不变时,屈服力随支座剪应变的增大而减小;剪应变不变时,屈服力随轴向荷载的增大而增大.

Background Gastroesophageal reflux disease with extra-esophageal symptoms, especially those with respiratory distress was attracting more and more attention. The related mechanisms were still in controversy. The purpose of the work was to explore airway inflammation triggered by gastroesophageal reflux. Methods Sixteen Sprague-Dawley rats were used as study group and 9 as control. In the study group, a plastic extender with a trumpet-shaped distal end was inserted into the lower esophagus to dilate the cardia, the pylorus was ligated. One ml of 0.1 mol/L hydrochloric acid was injected into the stomach. While a simple laparotomy was performed for control animals. All animals from two groups were sacrificed 24 hours after operation. Then tracheotomy was carried and the bronchoalveolar lavage fluid was collected in all animals. Cells in the fluid were counted and levels of interleukin （IL）-5, -6, -8 in it were measured. Results Compared with control group, the study group presented a neutrophil pattern of airway inflammation and an elevated concentration of IL-5, -6, -8 with no significant difference regarding eosinophil count. Conclusion The gastroesophageal reflux-triggered airway inflammation is characterized by a neutrophilic airway inflammation which differed from that caused by asthma, and enhanced levels of IL-5, -6 and -8, which are similar to that caused by asthma.

发达国家农业保险的福利化转型始于20世纪50年代。主要表现为主导模式的根本转变、基本地位的显著提升、政策目标的重大调整、财政投入的迅猛增长、保险范围的急剧扩大、保障程度的大幅提高以及实施方式的强制变革。这些转型的发生受到特定的经济、政治、社会政策和理论方面因素的影响。其对我国农业保险发展的重要启示意义是应循序渐进地推动农业保险的福利化转型、应恰当选择农业保险的政策目标、应充分发挥财政投入对农业保险的拉动效应、应适时推出福利保障性农业保险新产品、应积极推进农业保险实施方式的强制性变革。
