BACKGROUND： Hepatitis B virus（HBV）-related end-stage liver disease is the leading indication for liver transplantation in china, but long-term results of liver transplantation in patients aged over 60 years are not clear. The present study was to reveal the natural history of liver recipients with hepatitis B older than60 ***： The recipients who had received liver transplantation between December 2003 and December 2005 were divided into two groups： those equal or older than 60 years（older group,n60） and those younger than 60 years（younger group, n305）.Risk factors for poor long-term outcome in patients aged over 60 years were also ***： Except for age and preexisting chronic disease（P0.05）,no significant differences were observed in perioperative characteristics between the two groups. There was also no significant difference in HBV and hepatocellular carcinoma recurrence（P0.05）. The actuarial 1-, 3-, 5- and 8-year survival rates were 81.6%, 71.6%, 66.7% and 63.3% respectively for the older group vs 84.9%, 77.7%, 70.8% and 65.6% for the younger group（P0.05）. Multivariate analyses showed that pre-liver transplant renal insufficiency was a risk factor for poor outcome in the older group（odds ratio=3.615, P0.014）.CONCLUSIONS： Liver transplantation is safe and feasible for patients with HBV-related end-stage liver disease aged over 60years. Older patients with renal insufficiency should undergo transplantation earlier than younger patients.

依据我国商业银行1994-2012年操作风险历史数据,本文引入Lévy测度描述操作风险损失所具有的非连续跳跃行为,利用稀疏序列法产生动态操作风险损失过程,采用了同时考虑损失频率相关性和强度相关性的Lévy Copula模型,给出了具有时变参数和时变相关性结构的动态操作风险度量模型和数值实验技术,计算了不同置信水平上的VaR与CVaR.实证结果表明：Lévy Copula模型能在减少模型设定风险的同时,较好地描述风险单元间的相关性结构;Lévy Copula模型相比于传统Copula模型对相关性结构刻画更为细致,能降低风险资本,并且通过稳健性检验;动态Lévy Copula模型能捕捉到风险的变化趋势,减少由于时变参数导致的风险资本估计偏差.

1922年浦东日华纱厂的三次罢工,是由成立初期的中国共产党领导,兼具经济、政治双重斗争目标的工人运动。罢工期间,浦东纺织工会在中国劳动组合书记部领导下,多次与上海华界当局及日华纱厂厂方进行交涉和谈判。三次罢工声震沪上,浦东纺织工会亦在一段时期内获得小范围发展,与中共对上海华界当局内部非制度性因素的认识与利用是分不开的,具体体现在华界当局治理体系尚不健全、官员依据人情社会的行为逻辑处置罢工,以及地方社会政治生态复杂、政令不能统一这三个方面。
