中文摘要：

近年来,强迫症（OCD）的临床研究取得了一定进展。但由于人体研究的非侵入性等特点,很大程度上限制了对OCD的深入研究。动物模型可以突破人体研究的这一缺陷,使更精确地研究OCD的病理生理学机制成为可能。因而,众多的研究者试图采用基因敲除动物模型对OCD的发病机制进行更深入的探讨。该文主要对此类研究及其进展进行综述。

英文摘要：

Recently, some progress has been made in the clinical study of obsessive compulsive disorder （OCD）. Human research has inherent limitation because of its non-invasive nature, while animal models can break through the shortcomings of human research, allowing us to more accurately study the pathophysiology of OCD. Therefore, many researchers tried to use genetic knockout animal models to further study the etiology of OCD. In this review, recent progress about this kind of research was reviewed.
