近年来,在疼痛和镇痛研究领域已普遍重视建立模拟临床患者慢性或持续疼痛的实验模型。由于临床慢性疼痛是个复杂的神经病理与主观感受症状,产生原因多种多样,要求一个模型反映多种病因引起的慢性疼痛是相当困难的,研究人员需要针对研究的目的去选择或建立适用的疼痛模型。现将?

Because clinical chronic pain is a complex neuropathology and subjective symptom that occurs for a variety of reasons, it is quite difficult to require a model to reflect the chronic pain caused by multiple etiologies. Researchers need to select or establish appropriate pain for research purposes model. Now?
