摘要
临床研究通常以疗效为目的和导向,如何从治疗效果中厘清净效应和安慰效应是临床研究的重要问题.梳理安慰剂效应的涵义,认为临床中可能产生安慰剂效应的因素包括既往经验关联、患者期望、暗示、医患关系,并总结反安慰剂效应的特点、产生因素及对临床预后的影响.结合中医学特点,探讨设计能够体现安慰效应测量的针刺临床试验,试图对中医针刺疗效评价中的安慰剂效应做出更清晰的阐释.以原发性失眠症为例,设计前瞻性随机安慰剂对照试验,以观察和评价不同患者在同一医生诊治下针刺的治疗效果和安慰剂效应之间的关系,其组间比较有助于更好地区分不同情形下的临床效应.并尝试探讨安慰剂效应的反应人群,以及安慰剂在不同人群中的效应.
Abstract
Clinical research is usually aimed at and guided by therapeutic efficacy.Clarifying the placebo effect and the nocebo effect from treatment outcomes is an important issue in clinical research.This paper reviews the mean-ing of the placebo effect,suggesting that factors that may produce the placebo effect in clinical practice include past experience associations,patient expectations,suggestion,and doctor-patient relationships.It also summarizes the characteristics of the nocebo effect,its influencing factors,and its impact on clinical prognosis.Combining the characteristics of traditional Chinese medicine,this paper explores the design of acupuncture clinical trials that can reflect the measurement of the placebo effect,attempting to provide a clearer interpretation of the placebo effect in the evaluation of acupuncture efficacy in traditional Chinese medicine.Taking primary insomnia as an example,a pro-spective randomized placebo-controlled trial is designed to observe and evaluate the relationship between the treat-ment effects of acupuncture and the placebo effect in different patients under the treatment of the same doctor.Group comparisons will help better distinguish clinical effects in different situations.The authors also attempt to explore the responsive population to the placebo effect and the effects of placebos in different populations.
