The Earth’s natural pulse electromagnetic field data consists typically of an underlying variation tendency of intensity and *** change tendency may be related to the occurrence of earthquake *** of the underlying intensity trend plays an important role in the analysis of data and disaster *** chaos theory and the radial basis function neural network,this paper proposes a forecasting model of the chaotic radial basis function neural network to conduct underlying intensity trend forecasting by the Earth’s natural pulse electromagnetic field *** main strategy of this forecasting model is to obtain parameters as the basis for optimizing the radial basis function neural network and to forecast the reconstructed Earth’s natural pulse electromagnetic field *** verification experiments,we employ the 3 and 6 days’data of two channels as training samples to forecast the 14 and 21-day Earth’s natural pulse electromagnetic field data *** to the forecasting results and absolute error results,the chaotic radial basis function forecasting model can fit the fluctuation trend of the actual signal strength,effectively reduce the forecasting error compared with the traditional radial basis function ***,this network may be useful for studying the characteristics of the Earth’s natural pulse electromagnetic field signal before a strong earthquake and we hope it can contribute to the electromagnetic anomaly monitoring before the earthquake.

BACKGROUND： Phycocyanin can relieve decrease of mitochondrial membrane potential through reducing production of active oxygen so as to protect neurons after hypoxia/reoxygenation. OBJECTIVE： To observe the effect of phycocyanin on activity of PC12 cells and mitochondrial membrane potential after hypoxia/reoxygenation. DESIGN： Randomized controlled study SETTING ： Cerebrovascular Disease Institute of Affiliated Hospital, Medical College of Qingdao University MATERIALS： The experiment was carried out at the Key Laboratory of Prevention and Cure for cerebropathia in Shandong Province from October to December 2005. PC12 cells, rat chromaffin tumor cells, were provided by Storage Center of Wuhan University; phycocyanin was provided by Ocean Institute of Academia Sinica; Thiazoyl blue tetrazolium bromide （MTT） and rhodamine 123 were purchased from Sigma Company, USA; RPMI-1640 medium, fetal bovine serum and equine serum were purchased from Gibco Company, USA. METHODS： ① Culture of PC12 cells： PC12 cells were put into RPMI-1640 medium which contained 100 g/L heat inactivation equine serum and 0.05 volume fraction of fetal bovine serum and incubated in CO2 incubator at 37℃. Number of cells was regulated to 4 × 10^5 L 1, and cells were inoculated at 96-well culture plate. The final volume was 100μL. ② Model establishing and grouping： Cultured PC12 cells were randomly divided into three groups： phycocyanin group, model control group and non-hypoxia group. At 24 hours before hypoxia, culture solution in phycocyanin group was added with phycocyanin so as to make sure the final concentration of 3 g/L , but cells in model control group did not add with phycocyanin. Cells in non-hypoxia group were also randomly divided into adding phycocyanin group （the final concentration of 3 g/L） and non-adding phycocyanin group. Cells in model control group and phycocyanin group were cultured with hypoxia for 1 hour and reoxygenation for 1, 2 and 3 hours; meanwhile, cells in non-hypo

BACKGROUND ; Phycecyanin can anti-oxidize and clear free radial. Whether its protective effect on brain is related to Caspase-3, the promoter and operator of apoptosis, is highly concerned. OBJECTIVE： To observe phycocyanin for protecting nerve function and reducing the size of cerebral infarction of rats with brain ischemia-reperfusion and its effect on the expression of Cespese-3 mRNA. DESIGN ： A randomized controlled experiment. SETTING ： Institute of Cerebrovascular Disease, Affiliated Hospital of Medical College of Qingdao University MATERIALS： Totally 84 adult healthy female Wistar rats, weighing 210 to 250 g, of clean grade, were provided by the Animal Experimental Center of Shandong University. Phycocyanin （Institute of Oceanography of Chinese Academy of Sciences） was used. METHODS： This experiment was carried out in the Key Laboratory for Prevention and Treatment of Brain Diseases during May to December 2005. ① The rats were randomized into sham-operation group （n=4）, control group （n=-40） and phycocyanin-treated group （n=-40）. Middle cerebral artery occlusion/reperfusion （MACO/R） models were created on the rats of control and phycocyanin-treated groups with suture-occluded method by inserting a thread into left side extemal-internal carotid artery. In the sham-operatien group, inserting suture was omitted. After ischemia for 1 hour and reperfusion for 2 hours, suspension of phycocyanin was intragastdcaUy administrated into the rats of the phycocyanin-treated group at 100 mg/kg , and the same volume of normal saline was isochrenously administrated into the rats of control group as the same. ② Six rats were chosen respectively from the control group and phycocyanin-treated group, then neurologic impairment degrees of rats were evaluated according to Bederson＇s grading. ③ Six rats were chosen respectively from the control and phycocyanin-treated groups. The isolated brain tissue was stained with tdphenyltetrazolium chloride, and then the size of cerebral infa

从授权到控权:经济法的中国化路径

西方经济法的产生旨在授予政府干预经济的权力,但这并不适于解决当下的中国问题。行政权力过于庞大并日渐扩张的态势必然要求经济法予以有效回应,控权应当成为中国经济法的主旨。不论从法的一般属性,还是从经济法的独有特征来看,控权都能够与之兼容。我国经济法的现有制度虽有对控权功能的文本表达,但仍然不够,与法治经济实现的要求亦相去甚远。虽然行政法也以控权为己任,但其与经济法在控权对象和违法性审查标准等方面存在明显差异,只有将二者有机结合才可以形成对政府权力的有效控制。

保护道歉规则在医疗纠纷中的确立与运用

中外法学 2020年第6期32卷 1533-1552页

作者：陈云良广东外语外贸大学法学院

医疗道歉的法律性质属于证据。由于其主张的是对己方当事人不利的事实,因此构成诉讼外自认或者诉讼自认。保护道歉规则的目的在于揭露医疗错误以保护患者的健康权,其对医疗纠纷预防和处理制度、侵权法和民法总则的有效实施都具有促进功... 详细信息

医疗道歉的法律性质属于证据。由于其主张的是对己方当事人不利的事实,因此构成诉讼外自认或者诉讼自认。保护道歉规则的目的在于揭露医疗错误以保护患者的健康权,其对医疗纠纷预防和处理制度、侵权法和民法总则的有效实施都具有促进功能,可能减损的法益少于其必然增加的法益,且有助于修复和维持正常的医患关系,因此是可欲的。在保护范围上,存在部分道歉和全部道歉的区别。在模式上,存在证据规则型概括保护模式、意思通知型具体保护模式和意思表示型个案保护模式。我国应当确立针对全部道歉的意思通知型保护道歉规则,将诉讼外医疗道歉纳入保护范围。

民营经济专门立法的理据、定位及体系表达

民营经济是推动我国建成社会主义现代化强国,实现第二个百年奋斗目标的重要力量。从国家层面对民营经济进行专门立法是对民营经济由政策促进到立法保障的需要、是统筹推进国家立法与地方立法的需要、是优化民营经济发展环境的需要。基于我国现有民营经济规范的现实特征,考虑到立法功能的实现等原因,促进型立法应当是我国民营经济立法的定位选择,但是促进型立法因其软法规范较多可能带来权威不足,过于倚重激励机制可能导致手段和目标偏离,也需要提前预防。体系化是科学立法的关键维度,民营经济促进法在体系外部要合理衔接宪法、地方民营经济专门立法、其他单行立法以及民营经济政策;在体系内部,民营经济促进法要实现从目标到规范、从原则到规则两个层面的体系构建。

当前健康权研究缺乏对健康权规范模式的整体把握,缺乏系统的、从规范分析角度展开的讨论。从规范分析视角出发,以宪法基本权利的结构为分析框架,可以阐明健康权的规范构造,进一步说明健康权的权利属性和相应的治理对策。考察宪法基本权利体系理论的发展历程,基本权利构造经历了从二分到复合的变迁。健康权成为消极权利规范模式与积极权利规范模式共同作用的场域,因此健康权规范构造也必然呈现出复杂的结构。以复合结构为基本框架,以有效选择原则为权利复合结构的区分界限,对健康权的消极权利和积极权利进行规范构造,并明确健康权的限制机制。健康权的复合规范构造可以更合理地解决健康权规范构造的立法和司法应用,构建科学的健康权规范体系,明确公立医院的双重职能,正确定位民营医院的发展方向。

《基本医疗卫生与健康促进法》第21条规定了公民有接种免疫规划疫苗之义务。以该法条为脉络,对“预防接种”“免疫规划疫苗”“权利和义务”三大词汇进行规范分析非常有必要。探讨预防接种制度的划分,疫苗接种义务的理论起源,免疫规划疫苗的类型化与公民疫苗接种义务之关联性以及公民预防接种权利与义务之间如何调和之问题,可以促进该法条的正确理解与适用,并借此强化公民疫苗接种义务与责任意识,进一步构建强制接种制度。

采取以法定传染病为核心的传统分类治理模式,已经无法妥善化解新发传染病所带来的危害。将法律上的新发传染病单独作为一类来规定,摆脱法定传染病规制模式的局限,直接赋予县级政府采取甲类传染病防控措施的权力。在认定标准上,应当采取负面排除已知传染病和正面认定表面证据相结合的方式,建立容错免责机制,完善更正义务。为了将预防关口前移,应当采取预防型立法与"疫情应对规制金字塔"相结合的方式,既要授予行政主体判断权和裁量权,又要通过比例原则保障科学性和合法性,杜绝玩忽职守与滥用职权,形成良性的动态系统,以弥补公共卫生法体系应对新发传染病的缺陷。全球化背景下,传统的国际卫生条例规制逻辑不能有效应对新发传染病,为此有必要专门缔结"大流行病国际条约",同时推进《国际卫生条例(2005)》变革,才有可能真正使人类有效应对新发传染病带来的危机。
