It has been demonstrated that β-elemene could protect against carbon tetrachloride (CCl4)-induced liver fibrosis in our laboratory work, and the aim of this paper is to reveal the protective mechanisms of β-elemene. The hepatic fibrosis experimental model was induced by the hypodermical injection of CCl4 in Wistar male rats. β-elemene was intraperitoneally administered into rats for 8 weeks (0.1 mL/100 g bodyweight per day), and plasma endotoxin content was assayed by biochemistry. The serum TNF-α level was detected using radioactive immunity. CD14 expression in rat livers was measured by immunohistochemistry and Western blot. The results showed that β-elemene can downregulate the levels of plasma endotoxins, serum TNF-α, and hepatic CD14 expression in rats with liver fibrosis. β-elemene plays an important role in downregulating the lipopolysaccharide signal transduction pathway, a significant pathway in hepatic fibrosis development.

全生命周期成本分析框架下的电动公交充电器部署和车队管理 Article

尽管城市交通电气化快速发展,但电池电动公交车(EB)车队的系统规划和管理进展却较为落后。本研究首先综述了影响电池电动系统的基本问题,包括充电站部署、电池尺寸、公交车调度和生命周期分析。目前,EB系统的规划和运行是按顺序进行的,公交车调度是在公交车队和基础设施部署完毕后进行的,这导致了资源利用率低和资源浪费。对此,本文提出了混合整数规划模型整合充电站部署和公交车队管理,以尽可能低的生命周期成本(LCC),包括所有权、运营、维护和排放费用,缩小最佳规划与运营之间的差距。引入了分支定价算法,以减少寻找最佳解决方案所需的计算工作量。本研究还通过分析真实案
例,与目前的公交运营策略和充电站布局相比,一条公交线路的LCC优化后可显著降低30.4%。提出的方法不仅可以进行生命周期分析,还可以为交通部门和运营商提供可靠的充电桩部署及单线和多线的公交调度计划,这两者都是未来具有高电气化普及率的交通系统中决策支持的关键要求,此研究也有助于推动可持续交通的发展。

针对CAN总线中消息在固定优先级调度(FPS)算法下传输不可预知、低优先级消息容易被阻塞的问题,提出了一种基于时间触发机制的固定优先级调度(TT-FPS)算法,给出了最糟糕响应时间的计算方法。然后以纯电动汽车消息系统为例进行了TT-FPS的性能分析,验证了TT-FPS 较FPS有更好的性能。

Prevalence of asthma symptoms in Golestan schoolchildren aged 6–7 and 13–14 years in Northeast Iran

Asthma is the most common chronic disease among children, and its incidences are often imminent among elementary schoolchildren. This study aimed to examine the prevalence of asthma symptoms in Golestan schoolchildren aged 6–7 and 13–14 years in Northeast Iran. The prevalence rate was compared according to age group (aged 6–7 years vs. aged 13–14 years) and gender (male vs. female). In this cross-sectional study, 1706 Iranian schoolchildren aged 6–7 and 13–14 years in Golestan Province were enrolled. Participants completed questionnaires between February and July 2014. Asthma symptoms were assessed using the questionnaire of the International Study of Asthma and Allergies in Childhood protocol in Persian. The logistic regression model was used to estimate the odds ratios (ORs) and 95% confidence intervals (CIs) of the asthma symptoms for each of the gender and age groups. The prevalence rates of “current asthma” symptoms and “asthma ever” in all the children were estimated as 9.5% and 7.5%, respectively. The prevalence of asthma (“asthma ever” and “wheezing in the past 12 months”) in junior high schoolchildren (aged 13–14 years) is higher than that in elementary schoolchildren (aged 6–7 years) (P <0.05). The prevalence of the severity of wheezing in girls is lower than that in boys (OR= 1.7, 95%CI= 1.06–2.96, P = 0.02). Asthma is still a major public health problem. This study shows that the prevalence of the asthma symptoms in boys is lower than that in girls in both age groups, and the severity of asthma in girls is higher than that in boys aged 13–14 years.
