Explain disease related knowledge; According to the patient's situation, give personalized dietary guidance, establish regular eating habits, carefully evaluate the types of food in the food, and avoid spicy stimulation, gas production, high fat and other foods that are easy to cause intestinal discomfort. SMS follow-up was conducted 3 days after discharge, and weekly phone follow-up was conducted to see if patients needed to solve problems and help them solve them in time.

AID knowledge education was given to patients in the intervention group after admission. At the same time, patients are asked to pay attention to the "anti-inflammatory diet" wechat mini program developed by researchers, and teach patients how to use it, including the choice of anti-inflammatory diet, inappropriate anti-inflammatory diet, diet alarm clock, diet notes and other related functions. Missionary patients persisted with AID until re-examination 8 weeks later.

The researchers conducted weekly telephone follow-up to urge the patients to adhere to the AID diet, answer the questions raised by the patients during the implementation process, and understand the patients' knowledge acceptance and diet implementation. Follow-up is carried out by qualified members of the training research team. Follow-up can take the form of face-to-face visit to the community or direct telephone follow-up, and make follow-up records.

Patients in the intervention group were given AID knowledge education, and patients were asked to pay attention to the "anti-inflammatory diet" wechat mini program developed by the researchers to teach patients how to use it, including the selection of anti-inflammatory diet, unsuitable anti-inflammatory diet, diet alarm clock, diet notes and other related functions. The missionary patients insisted on AID until reexamination 8 weeks later.

C-reactive protein (mg/L) is a non-specific inflammatory marker. It is an acute phase reaction protein synthesized by the liver to protect the body when pathogenic microorganisms invade the body.

Erythrocyte sedimentation rate (mm/h) refers to the rate of erythrocyte sedimentation under certain conditions. The anticoagulant blood is placed in a vertically erected small glass tube. Due to the large proportion of red blood cells, it is naturally sunk by gravity. Under normal circumstances, the subsidence is very slow. The rate of erythrocyte sedimentation is often expressed by the distance of red blood cells sinking at the end of the first hour, called ESR.

White blood cells are colorless, spherical, nucleated blood cells. The total number of normal adults is (4.0 ~ 10.0)x 109/L, which can change in a certain range depending on the time of day and the functional state of the body.

This table, compiled by Zung in 1971, is used in SAS for a total of 20 symptom categories, with a score of 1 to 4 after each problem. The scoring scale is: "1" indicates that the symptom is rarely present; A score of "2" indicates that this symptom is sometimes present; A score of "3" indicates that the symptoms are present most of the time; A score of "4" indicates symptoms most of the time. The cut-off value of SAS standard score is 50 points, of which < 50 is no anxiety, 50 to 59 is mild anxiety, 60 to 69 is moderate anxiety, and more than 70 is severe anxiety.
