目的:观察孕酮对于吗啡所致奖赏效应及下丘脑、纹状体内单胺类神经递质水平的影响。方法:采用大鼠条件性位置偏爱(CPP)模型,建立离体电化学检测技术高效液相色谱法测定大鼠下丘脑及纹状体内去甲肾上腺素(NE)、多巴胺(DA)和5-羟色胺(5-HT)的含量。结果:吗啡(5mg·kg-1)可诱导大鼠产生稳定的CPP效应;孕酮(5mg·kg-1及20mg·kg-1)本身不产生CPP效应,但能抑制吗啡诱导的CPP效应。与对照组比较,吗啡诱导CPP形成时,下丘脑内NE水平明显升高(P<0.05),纹状体内NE、DA和HT的水平明显升高(P<0.05,P<0.01)。与吗啡组比较,合用20mg·kg-1孕酮使纹状体内DA水平显著下降(P<0.01)。结论:孕酮对吗啡的CPP效应具有一定的抑制作用,其机制可能与降低纹状体内DA水平有关。

The introduction of automated vehicles (AVs) is expected to improve the safety and traffic efficiency of the transportation system. However， the impacts of AVs on pedestrian-vehicle interactions (PVIs) remain unclear， especially under the mixed traffic flow condition with AVs and conventional vehicles (CVs). The objective of this paper is to investigate PVIs under AV mixed traffic flow at unsignalized mid-block crosswalk (UMC) where the right of way competition exists and the traffic conditions are more complex. An agent-based simulation model is proposed to evaluate the safety and traffic efficiency under a diverse range of different scenarios. Some agents’ behavioral parameters are calibrated from trajectory and video data collected at two sites in Nanjing. The proposed model is also validated by comparing Post-Encroachment Time (PET) and pedestrian waiting time outputted from simulation with those extracted from empirical data. The simulation results suggest that the introduction of AVs has limited effect on both safety and efficiency levels at UMC under the low AV penetration rate. Compared to the negotiated yielding strategy of AVs， the conservative yielding strategy performs better in terms of pedestrian safety， but worse in improving traffic efficiency. Moreover， the results reveal that pedestrian and vehicle volumes， the proportion of pedestrians familiar with AVs， and the proportion of risk-prone pedestrians could significantly affect the safety and efficiency levels at UMC. Lastly， we provide some practical recommendations for determining treatments for mid-block crosswalks with AV mixed traffic flow to improve pedestrian safety and traffic efficiency.
