Methods A left ventriclepump-descending aorta bypass model was established in five healthy sheep (60 70 kg) and the circulation ofthese sheep was assisted by FW-Ⅱaxial blood pump for 2 weeks. At preoperative and postoperative day 1,2,3,7。展开更多

Compared to the type-1 fuzzy set, type-2 fuzzy sets have more advantages in handling the model based on uncertainties, linguistic information because the membership functions are fuzzy sets. Different membership functions are established for each factor when the unmanned vehicle is driving at different speed intervals. In addition, a new evaluation method is developed to analyze unmanned vehicle’s driving state. Finally, a set of dynamic fuzzy rules are sorted out, which can be applied to the unmanned vehicle’s behavioral decision-making and provide a new idea to related research.展开更多

Study selection Studies were included if they had data on misoprostol and labour induction. Altogether 623 articles were found and 124 were admitted, including 19 287 cases. Data extraction Data were collected on efficacy and incidence of side-effects of misoprostol and oxytocin. Data were checked for consistency within the published articles and converted into a standard format for incorporation into a centra l database. Data synthesis The average successful induction rate, rates of caesarean section; incidence of tachysystole, hypertonus of uterus and precipitous labour, and rates of meconium stained amniotic fluid between the misoprostol and oxytocin groups were significantly different (P<0.05). There were no significant differences between the two groups concerning the average interval from the administration of misoprostol and oxytocin to the onset of labour, duration of the total stage of labour, incidence rate of foetal distress, neonatal asphyxia (1-minute Apgar score≤7), post partum haemorrhage or amount of blood loss in postpartum.Conclusions Misoprostol is a superior agent over oxytocin on the induction of term labour, but its application might increase the risk of prec ipitatous labour, abnormal uterine contractions or meconium stained amniotic fluid. Therefore, the doasges and regimens of the agent need further investigation.展开更多
