Background
The tree shrews are small mammals mainly distributed in southwest areas of China, and genome research shows that the genetic relationship of the tree shrews is closest to that of primates (about 93.4 percent), and compared with the primates, the tree shrews have the characteristics of small body size, short reproduction period, easiness in experimental operation, low feeding cost and the like, and have unique application advantages in the research of animal models of human diseases. The tree shrew has high brain mass ratio, a developed nervous system and a stress system similar to human beings, so the tree shrew is widely applied to the study of neuropsychiatric diseases.
Anxiety, depression, and depression are common affective disorders of the nervous system, and both are frequently associated. At present, the anxiety/depression phenotype of model animals is mainly evaluated by different behavioral testing methods to simulate different symptoms under human disease states through behavioral means, for example, a sugar water preference test for depression is a core symptom simulating anhedonia of patients, and an open field test is used for simulating the spontaneous activity and exploration capacity of human beings. The elevated plus maze simulates the anxiety state of human beings by the contradiction psychology formed between the exploration characteristics of animals in a new environment and the fear characteristics of animals in a highly suspended open environment, and is the most classical instrument for detecting the anxiety behaviors of animals. However, the tree shrew is good in climbing and jumping, agile in movement, small in gallbladder and easy to fright, the traditional elevated plus maze is not suitable for being used, and compared with the mode that the depression behavior of the tree shrew can be evaluated by a sweet water preference experiment and an improved open field experiment, an instrument for evaluating the anxiety behavior is not available, and the tree shrew is very inconvenient to use for researching the diseases such as anxiety, anxiety depression and the like.
