收集了1960年至2008年滇池水质及社会、经济指标,应用相关性分析方法,对滇池流域人口、昆明市GDP的增长与滇池TN, TP, CODMn之间的关系进行了研究。结果显示,滇池水体富营养化程度与滇池流域人口、昆明市GDP密切正相关,流域人口增加、经济发展是滇池水体富营养化的主要原因。社会经济发展对滇池草海水体所造成的压力高于外海,且草海水质有继续恶化的趋势。由于滇池综合治理工作的不断推进,特别是2000年滇池水污染防治“十五”计划实施以来,滇池流域社会经济发展对滇池外海水质的影响有所减轻,外海水质继续恶化的趋势得到初步遏制。

基于系统工程的思想,通过分析高速公路社会经济效益产生的机制,建立了区域经济—公路交通发展系统动力学模型,以天津市津蓟高速公路为例,通过系统仿真误差检验,证实了该系统动力学模型的仿真效果较好、性能稳定。通过已建—未建高速公路系统仿真结果的有无对比,计算并预测出了津蓟高速公路2003—2013年各年的社会经济效益,从而实现了高速公路项目社会经济效益评价的定量化目标,为今后类似项目的开展提供了理论指导。

The risk factors, especially laboratory indicators, of prognosis after acute kidney injury (AKI) remain unclear. We conducted a retrospective survey of Chinese People’s Liberation Army General Hospital from January 1, 2012 to December 31, 2012 according to the AKI diagnosis standard issued by Kidney Disease Improving Global Outcomes. The epidemiological features and factors influencing hospital mortality and renal function recovery were evaluated through logistic regression analysis. Among 77 662 cases of hospitalized patients, 1387 suffered from AKI. The incidence rate and mortality of AKI were 1.79% and 14.56%, respectively. Multivariate logistic regression analysis revealed that high AKI stage, age greater than 80 years, neoplastic disease, low cardiac output, increased white blood cell count, and decreased platelet count and serum albumin levels were the risk factors affecting the mortality of AKI patients. Conversely, body mass index between 28 and 34.9 was a protective factor. Increased AKI stage, tumor disease, post-cardiopulmonary resuscitation, and RRT were the risk factors of renal function recovery upon discharge. In addition to traditional risk factors, white blood cell count, platelet count, albumin, and BMI were the predictors of the mortality of AKI patients. No laboratory indicators were found to be the risk factors of renal function recovery in AKI patients.
