Research progress on animal models of chronic pain and its application in traditional Chinese medicine research / 中国中药杂志

ABSTRACT

The classification of chronic pain is complex and its pathogenesis is not clear, which led to the limited progress of treatment measures.Traditional Chinese medicine(TCM) has certain advantages in the treatment of chronic pain, and its mechanism needs further exploration. The ideal animal model is helpful to elucidate the key mechanism of the occurrence and development of chronic pain and play an important role in the discovery of new drug targets, the development of new therapies and the research on the analgesic mechanism of TCM.In recent years, many scholars at home and abroad have done a lot of research to explore the pathogenesis of chronic pain and the mechanism of TCM, which have achieved some results. On this basis, this study summarizes the selection of experimental animals for chronic pain and the commonly evaluation methods of animal models. According to the latest international classification of diseases, this review organizes the induced methods, evaluation indicators, advantages and disadvantages of seven kinds of chronic pain animal models, such as chronic primary pain, chronic cancer-related pain and so on. Next, this review introduces the chronic pain animal models commonly used in TCM research, in order to provide guidance for the targeted selection of animal models when carrying out relevant experiments in the future.
