Through clinical observation, it can be found that patients who are in a state of anxiety, nervousness and fear, or depressed personality after the disease have a poor prognosis, while some patients who are unaware of the disease, or have a more cheerful and optimistic personality, and are able to release their emotions, tend to have a better prognosis. Experimental studies have also shown that changes in mood can affect immune function, and adverse emotions can lead to a decline in immune function and promote the occurrence and development of disease. Therefore, in the process of clinical treatment, not only should we be good at medication, but also focus on emotional treatment, so that patients can maintain a good and healthy state of mind, which is conducive to the treatment of disease.
