Women with a history of preterm delivery had double the risk for ischemic heart disease, stroke or other cardiovascular disease compared with those without such a history, and the association was independent of other risks. The reasons remain unclear. 具有早产史的妇女发生缺血性心脏病、中风和其他心血管疾病的风险是无早产史的妇女的两倍,且该相关性与其他风险因素无关。
This paper discusses number air cylinder's stroke design, establishes the calculating equation of piston component stroke and delivery stroke series size, works out relevant calculating frame, thus providing an efficient method and theoretical basis for the stroke design of number air cylinder. 研究了数字气缸的行程设计方法,建立了活塞分行程和输出行程系列值的计算方程,编制了相应的计算框图,可为数字气缸的行程设计提供一种有效的方法和理论依据。
The results of this project could explore and summarize puerarin brain targeted delivery system, provide a theoretical basis, and provide a new idea and method for the treatment of ischemic stroke. 本课题研究为探讨和总结葛根素脑靶向给药系统提供了实验依据,为缺血性脑卒中治疗探索新思路和新方法。
