[0040] Example 1

[0041] According to one embodiment of the present invention, a model of low-intensity intermittent stress is provided, as shown in FIG1 , including:

[0042] Observe the target object within a set time, wherein the set time includes five time periods, each time period including three days;

[0043] S100: Observe the target's social stress on the first day and record the target's behavior;

[0044] S200: On the second day, the target is subjected to restraint stress observation and its behavior is recorded;

[0045] S300: On the third day, no intervention is performed on the target, and the target's behavior is recorded;

[0046] Repeat the above operation for three days as a group until the five time periods of the target object are recorded.

[0047] The low-intensity intermittent stress model and device in the embodiment of the present invention observes the target body within a set time, wherein the set time includes five groups of time periods, each group of time periods includes three days. Through each group of three days of stress observation, the target body's response to stress is obtained. See Table 1

[0048] Table 1

[0049] In one embodiment, social pressure is observed as:

[0050] Record the first target and the second target in the same environment;

[0051] Observe whether a target object in the same environment attacks another target object. If a first target object attacks a second target object within a preset time, the first target object is marked as aggressive.

[0052] For example, the target object is set as mice. Under social stress environment, mice marked as CD1 are housed in single cages for 7 days to develop territorial awareness, and C57BL / 6 mice are housed for four to five days to adapt to the environment.

[0053] Screen CD1 mice for aggressiveness by placing C57BL / 6 mice in the cage of CD1 mice for three minutes. If the CD1 mice initiate attacks more than five times with an attack latency of less than one minute, they are considered aggressive. If they are aggressive at least twice in 3 days, they can be used as attacking mice in the model.

[0054] The experimental group of C57BL / 6 mice were placed in a CD1 mouse cage and isolated with a transparent acrylic plate with holes for 24 hours after being challenged for five to ten minutes. New CD1 mice were replaced every day to avoid adaptation.

[0055] In one embodiment, the sugar water preference test comprises:

[0056] Four groups of test subjects were set up to test the sugar water preference, including the olfactory bulbectomy group, the sham operation group, the olfactory bulbectomy plus low-intensity intermittent stress group, and the sham operation plus low-intensity intermittent stress group.

[0057] Referring to Figure 3 , the mice in the olfactory bulbectomy group showed a lower percentage of sugar water preference compared to the sham operation group, and the mice in the olfactory bulbectomy plus low-intensity intermittent stress group showed a higher percentage of sugar water preference compared to the mice in the simple olfactory bulbectomy group.

[0058] The model of this application can also be used to conduct experiments on low-intensity intermittent stress in humans: specific stress tasks can be formulated according to the characteristics of specific patients, and such tasks are conducive to improving the patient's own value and ability. The total paradigm time is 30 days, with 2 days of each stress and 1 day of interval, for a total of 10 cycles.

[0059] This application constructs a low-intensity intermittent stress model from the perspective of adaptability to stress to reduce the sensitivity of depression to stress, thereby being used for the treatment of depression; this model paradigm is low-cost, simple, and highly operational, which is conducive to the promotion of future clinical trials.

[0071] In one embodiment, the apparatus further comprises:

[0072] The sugar water test module is used to test the target's preference for sugar water.

[0073] In one embodiment, the sugar water testing module comprises:
