Background
Cancer-related fatigue (CRF), also known as cancer-related fatigue, is one of the common symptoms of clinical malignancies, and the NCCN guidelines describe CRF as "an unsettling, persistent, subjective feeling of fatigue and failure of energy in the body, emotion and/or cognition, and interfering with daily life and function caused by tumor or anti-tumor therapy"; international disease classification standard 10 th edition (ICD 10) describes the symptoms of CRF as nonspecific weakness, general decline, lethargy, fatigue. It has persistent and non-universal characteristics, such as weakness, exercise intolerance, inattention, reduced motivation or interest; broadly, CRF is a multi-dimensional subjective experience of individual patients in terms of physiology, psychology, functionality and sociality.
In summary, CRF is a subjective feeling of fatigue, usually characterized by a decrease in physical strength and energy, due to a series of subjective feelings resulting from long-term stress and pain of patients caused by cancer and related treatments; unlike general fatigue, CRF has characteristics of high severity, disproportionate to activity or energy output, inability to be alleviated by sleep and rest, long duration, etc.; in clinic, there are various manifestations such as lack of energy, weakness, laziness, apathy, poor thought, hypomnesis, depression, etc.; CRF can seriously affect the physical, psychological and social functioning of the patient, as well as the quality of life.

6.2 mental fatigue test results
The mouse open field experiment can be used as one of evaluation criteria of mental fatigue; observing the activity of the mouse in the middle lattice of the open box, wherein the activity comprises the stay times in the middle lattice, the crossing times among the squares, namely the times of spanning more than three claws into the adjacent lattice, and the standing time, namely the time of more than 1cm above the ground for two forelimbs; the more the number of times of center stay, the more mental fatigue; the results in Table 3 show that the number of open field center stays of the mice in the Lewis lung cancer group is significantly higher than that in the blank control group: (*p<0.05); after the prognosis of drug administration, the number of stay times in the open field center of each group of mice is obviously lower than that of the Lewis lung cancer group: (###p<0.001), mental fatigue is remarkably relieved.

6.3 physical fatigue test results
The mouse tail suspension experiment can be used as one of evaluation standards of physical fatigue; fixing a 2cm part of the tail end of each mouse to enable the mouse to be in an inverted hanging state, enabling the head of each mouse to be 5-6 cm away from the ground, separating the sight lines of adjacent animals by using a wood board, adapting for 1min, and recording the accumulated motionless time of each mouse within 5 min; the shorter the struggling time of the mouse is, the more fatigue the mouse is; the results in Table 3 show that the ratio of struggling time of Lewis lung cancer mice is significantly lower than that of the blank control group (**p<0.01); after drug intervention, the struggling time ratio of each group of mice is obviously higher than that of Lewis lung cancer group: (#p<0.05), the fatigue of physical strength is relieved to a certain extent.
In addition, the exhaustive swimming test can also be used as another evaluation standard of physical fatigue; preparing a weight equivalent to 7% of the weight of a mouse, adhering the weight to the tail of the mouse by using a medical adhesive tape, putting the mouse into a swimming box with the water temperature of 25 +/-1 ℃ for swimming test until the force is exhausted and the mouse cannot sink, and recording the elapsed time; the shorter the mouse moves in water, the more fatigued the mouse is; the results are shown in Table 4, the struggling time of Lewis lung cancer miceThe ratio is significantly lower than that of a blank control group (***p<0.001); after the drug is administered for a dry dose, except for the cyclophosphamide group (*p>0.05), the struggling time ratio of each group of mice is obviously higher than that of Lewis lung cancer group: (#p<0.05), physical fatigue is remarkably relieved; because cyclophosphamide has multi-system toxicity, the physical fatigue of experimental mice of the cyclophosphamide group is presumed to be caused by the accumulated toxicity of the cyclophosphamide; and the other combination groups can effectively improve the physical fatigue of the mice.
