巨灾风险证券化研究

在金融证券化和保险金融化的趋势下,巨灾风险证券化的出现为保险业实施巨灾风险保险融资或转移巨灾风险提供了有效地解决方法。巨灾风险证券化的主要类型有巨灾期货、巨灾债券、巨灾期权、巨灾互换以及或有资本票据,其操作需要专业化的交易主体和适当的触发机制。我国发展巨灾风险证券化的策略是要正确认识发展巨灾风险证券化的必要性,有步骤地进行巨灾风险证券化的开发与设计以及完善巨灾风险证券化发展的外部环境。

Cross-correlation matrix analysis of Chinese and American bank stocks in subprime crisis

In order to study the universality of the interactions among different markets, we analyze the cross-correlation matrix of the price of the Chinese and American bank stocks. We then find that the stock prices of the emerging market are more correlated than that of the developed market. Considering that the values of the components for the eigenvector may be positive or negative, we analyze the differences between two markets in combination with the endogenous and exogenous events which influence the financial markets. We find that the sparse pattern of components of eigenvectors out of the threshold value has no change in American bank stocks before and after the subprime crisis. However, it changes from sparse to dense for Chinese bank stocks. By using the threshold value to exclude the external factors, we simulate the interactions in financial markets.

浅谈糖尿病周围神经病变的发病机制及诊疗

糖尿病周围神经病变(diabetic peripheral neuropathy,DPN)作为糖尿病最常见的并发症之一,其发病率高达30%-50%。其发病症状多样,严重时可间接引起足部溃疡,甚至需要截肢,这使得糖尿病患者的生活质量明显下降。因此,我们将从糖尿病周围神经病变的发病机制开始探讨,进一步学习其诊断方法,最后多方面、系统的了解治疗方案。在临床工作中,利用中西医相结合的方法进行综合治疗,能给糖尿病周围神经病变患者的长期预后带来很大益处。
