新型冠状病毒感染(新冠病毒感染)是主要累及呼吸系统的一种传染性疾病,可同时伴有心脏和神经系统等多器官多系统损害[1]。新冠病毒感染后综合征(长新冠)是新冠病毒感染后持续超过两个月且不能由其他病因解释的气短、疲劳、头痛和心悸等症状[2]。目前,我国有约49%~76%的新冠病毒感染患者受到长新冠影响,其中,失眠是其临床求诊最常见主诉[3,4]。失眠也是冠状动脉粥样硬化性心脏病(冠心病)的常见合并症,对于合并新冠病毒感染的冠心病患者,失眠则作为长新冠症状之一,直接影响患者预后与康复[5]。目前,针对冠心病患者“长新冠”失眠的西医临床治疗多采用苯二氮䓬类催眠药物,但由于其疗效短暂、药物依赖与耐受等问题,多数患者仍长期受失眠困扰。

The development of green route for preparing propylene oxide (PO) with molecular oxygen is of significance both in academic and industrial. In this work, propylene epoxidation coupled with furfural oxidation catalyzed by platinum meso-tetraphenylporphyrin (Pt (II)TPP) has been developed. Propylene conversion and PO selectivity reached up to 56%and 83%, respectively. Meanwhile, furfural was almost completely converted to furoic *** on operando characterizations and electron paramagnetic resonance (EPR) tests, a mechanism involved high-valent Pt species was proposed. This work is expected to provide a potential application prospects for producing PO and furoic acid simultaneously in chemical industry.
