文章利用水位自回归与多元回归相耦合模型,建立了与开采量、降水量相关的水位递推方程;在地下水水位不低于设定水位的约束下,设计岩溶水合理开采量,讨论了外调水支持下的岩溶水开采策略,并对开采量与临界水位的动态关系进行了研究。结果表明,利用水位递推方程可以计算临界水位控制条件下的合理开采量,当采用7.5 m作为管理控制的临界水位,开采强度可控制在22.05×10^(4) m^(3)/d左右,可为未来外调水支持下淮北市岩溶水开采方案的制定提供一定的参考依据。

Stroke & Vascular Neurology 2019年第2期4卷 93-95页

作者： Jieru Wan honglei ren Jian Wang Department of Anesthesiology and Critical Care Medicine Johns Hopkins School of MedicineBaltimoreMarylandUSA

Intracerebral haemorrhage (ICH) is a devastating type of stroke with high mortality and morbidity. However, we have few options for ICH therapy and limited knowledge about post-ICH neuronal death and related mechanisms. In the aftermath of ICH, iron overload within the perihaematomal region can induce lethal reactive oxygen species (ROS) production and lipid peroxidation, which contribute to secondary brain injury. Indeed, iron chelation therapy has shown efficacy in preclinical ICH studies. Recently, an iron-dependent form of non-apoptotic cell death known as ferroptosis was identified. It is characterised by an accumulation of iron-induced lipid ROS, which leads to intracellular oxidative stress. The ROS cause damage to nucleic acids, proteins and lipid membranes, and eventually cell death. Recently, we and others discovered that ferroptosis does occur after haemorrhagic stroke in vitro and in vivo and contributes to neuronal death. Inhibition of ferroptosis is beneficial in several in vivo and in vitro ICH conditions. This minireview summarises current research on iron toxicity, lipid peroxidation and ferroptosis in the pathomechanisms of ICH, the underlying molecular mechanisms of ferroptosis and the potential for combined therapeutic strategies. Understanding the role of ferroptosis after ICH will provide a vital foundation for cell death-based ICH treatment and prevention.
