道宣晚年的作品,集中体现了道宣通过对戒相的要求所表达出来的佛教表现艺术美学观念。道宣是继道安之后对中国戒相影响最大的高僧,也可以说是佛教表现艺术的重要理论家。他把服装、形体都作为一种彰显思想的表现形式,甚至要求达到能以其艺术度化众生的高度。他认为在一个文盲充斥、便餐兴盛的社会里,靠听觉和视觉感官接受的传媒是最捷便的,而通过文字乃至思考才能获得的教益,往往被排斥或疏离。同时,他为记录和表彰在表现艺术方面有所建树的僧侣开辟了蹊径。

文章利用ADB数据库63个经济体35个部门国际投入产出表,将各国贸易增加值进行分解,并通过构建贸易依赖新指标测算2007~2022年各经济体对中美两国最终品出口、中间品出口和产业链支撑方面的贸易依赖程度,以此评估中美经贸影响力。文章发现:在世界主要国家(地区),中美两国经贸影响力都呈现上升态势;相比于其他国家对美国的最终品出口依赖,中国在中间品出口依赖和产业链支撑依赖方面更占优势,且中国在最终品出口方面的影响力也不断增加。根据中美经贸影响力特点,文章给出相应政策建议。

阿片类药物在疼痛治疗中发挥重要作用,但其在有效控制各类型急性和慢性疼痛的同时,也带来非医疗目的用药和药物成瘾的风险,造成阿片类药物危机。阿片受体在中枢神经系统广泛分布,介导复杂的生物学效应。阿片类镇痛药物的不良反应如呼吸抑制、依赖和成瘾等严重限制了其临床应用。目前,低成瘾性阿片类镇痛药物研发策略主要包括防滥用新制剂、靶向外周的阿片受体激动剂、阿片受体G蛋白信号通路偏向性激动剂、阿片受体异聚体激动剂和阿片受体多功能配体等,大部分正在进行非临床或临床研究,有一些新制剂药物已经上市。但这些措施在产生镇痛或其他治疗益处的同时,仍在一定程度上保留了传统阿片类镇痛药物的潜在滥用风险和其他不良反应,如何将镇痛作用与成瘾潜能完全分离面临重大挑战。因此,新型低成瘾性阿片类镇痛药物的研发仍需更多努力。
