目的探索盐阈值与外周动脉粥样硬化的相关性,为预防外周动脉粥样硬化发生、发展提供科学依据。方法采用横断面研究设计,选取2017年12月至2019年1月陆军军医大学大坪医院心血管内科住院的2079例患者为研究对象,应用梯度浓度的NaCl溶液测定患者的盐阈值(测试实施者遵循盲法),而后进行双侧颈动脉和双侧股动脉超声检查,根据是否存在外周动脉粥样斑块分为外周动脉粥样斑块组和无外周动脉粥样斑块组,比较两组盐阈值并分析盐阈值与外周动脉粥样硬化的关系。结果外周动脉粥样斑块组盐阈值明显高于无外周动脉粥样斑块组[(0.07±0.04)vs.(0.05±0.04),P<0.05]。多因素logistic回归模型在控制外周动脉粥样硬化的传统危险因素后,发现盐阈值不独立增加外周动脉粥样斑块发生的风险[(OR=0.919,95%CI:0.477~1.774),P=0.802]。结论外周动脉粥样斑块患者的盐阈值较高,但盐阈值升高不是发生外周动脉粥样硬化的独立危险因素。

A series of ternary organic photovoltaics(OPVs) are fabricated with one wide bandgap polymer D18-Cl as donor, and well compatible Y6 and Y6-1O as acceptor. The open-circuit-voltage(V)of ternary OPVs is monotonously increased along with the incorporation of Y6-1O, indicating that the alloy state should be formed between Y6 and Y6-1O due to their excellent compatibility. The energy loss can be minimized by incorporating Y6-1 O, leading to the VOC improvement of ternary OPVs. By finely adjusting the Y6-1O content, a power conversion efficiency of 17.91% is achieved in the optimal ternary OPVs with 30 wt% Y6-1O in acceptors, resulting from synchronously improved short-circuit-current density(JSC) of 25.87 mA cm, fill factor(FF) of 76.92% and VOC of 0.900 V in comparison with those of D18-Cl : Y6 binary OPVs. The JSC and FF improvement of ternary OPVs should be ascribed to comprehensively optimal photon harvesting, exciton dissociation and charge transport in ternary active layers. The more efficient charge separation and transport process in ternary active layers can be confirmed by the magnetophotocurrent and impedance spectroscopy experimental results, respectively. This work provides new insight into constructing highly efficient ternary OPVs with well compatible Y6 and its derivative as acceptor.
