Cancer patients should enter a long-term rehabilitation stage after receiving comprehensive treatment in the hospital. Through clinical observation, tumor patients can control tumor recurrence to the maximum extent as long as they keep a good mood, treat their work and life optimistically, adjust their diet and daily life under the guidance of TCM health preservation theory, actively participate in self-care, rationally adjust their diet, calm their secular desires, gradually adjust the imbalance between Yin and Yang with TCM holistic view, and improve their immune function and anti-cancer ability. Specifically, it can be realized from the following points: 1. Mental health care needs to forge ahead and relax. Generally, cancer patients are nervous, and work pressure keeps their cerebral cortex in a state of tension for a long time. Modern medicine believes that diseases caused by bad emotions do not directly lead to certain diseases like bacteria and viruses, but act through the cerebral cortex, nerves and endocrine system, such as increased adrenal secretion when angry and nervous, deepened breathing and accelerated heartbeat. When panic occurs, breathing will be temporarily suppressed, causing peripheral blood vessels to contract, turn white, sweat, dry mouth and other phenomena; When you are sad, it will inhibit gastrointestinal peristalsis and the secretion of digestive juice, making people lose appetite and have a tasteless diet. Many experiments have confirmed that various stress factors can affect the formation and growth rate of tumors and also change the function of immune system. "Smile, already ten years old; I am embarrassed and my head is white. " It shows that optimism can make people live a long and healthy life, naturally enhance people's disease resistance and achieve the purpose of mental health care. The principle of mental health care is to pay attention to recuperate the spirit, avoid malignant stimulation, pay attention to the changes of patients' mental emotions, and enhance patients' self-control and adjustment ability of emotions. We can eliminate the fear, tension, depression and resentment of patients, enhance confidence, nourish body and mind, and achieve the purpose of mental health care and conditioning. According to patients' temperament and hobbies, it is suggested that tumor patients do some healthy recreational activities and guide them to practice Qigong, yoga, Tai Ji Chuan, listening to music, playing the piano, playing chess, calligraphy, painting, flower protection, keeping birds, fishing, collecting and appreciating. Give full play to one's talents, shift one's pessimism, cultivate one's spirit, make one's life richer and better, and make patients realize that their leisure life is more enjoyable. Just like the cloud in Inner Diameter: take pleasure as the service and self-satisfaction as the merit. This is the wisdom of mental health. 2, diet health conditioning people take food as the sky, people take Shui Gu as the foundation, diet is the material basis for nourishing the body to maintain life, a reasonable diet can enhance physical fitness, resist exogenous pathogens, and prevent diseases. "Inner Diameter" says: "Five grains are the supplement, five animals are the benefit, five fruits are the help, five vegetables are the filling, and the smell is combined into essence." In the recovery period of cancer patients, if we can pay attention to regulating diet, we can achieve the goal of healthy diet. On the contrary, improper diet and improper regulation will lead to the occurrence of diseases and will also promote the deterioration of diseases. Tumor patients can generally show deficiency/excess, and deficiency is weakness of vital qi, which can be mainly divided into qi deficiency, blood deficiency, yin deficiency and yang deficiency. The principle of regulation is to replenish qi and blood, nourish yin and warm yang. It can be divided into qi stagnation, blood stasis, phlegm turbidity, dampness stagnation, damp heat, excess heat, heat toxin and so on. Its conditioning principles are regulating qi, promoting blood circulation, resolving phlegm, inducing diuresis, clearing damp-heat, clearing away heat and toxic materials, and replenishing deficiency clinically according to the theory of "nourishing energy and eliminating oneself" in traditional Chinese medicine. Clinical and experimental studies have proved that ginseng, tremella, almonds, mulberries, lentils, mushrooms, sword beans, coix seed and other foods can promote lymphocyte transformation; Ginseng, yam, dark plum, garlic and snake meat can improve the phagocytosis of macrophages; Goose blood, mushrooms and melons can increase the proportion of cells; Ginseng and licorice have adrenocortical hormone-like effects; Ginseng, yam, ganoderma lucidum, etc. Can regulate nucleic acid and protein metabolism; Placenta, longan, venison, bovine bone marrow, Radix Astragali, Radix Codonopsis and Fructus Lycii can increase red blood cells and hemoglobin; Spatholobus suberectus, longan pulp, peanut, soft-shelled turtle, placenta, ginseng and astragalus can increase white blood cells; Longan meat, peanuts, red dates and placenta can all increase platelets. Hawthorn, garlic, safflower, hairyvein agrimony, pangolin and notoginseng have the effect of inhibiting the growth of cancer cells; Bitter gourd, watermelon, sugarcane, kiwi fruit, Prunella vulgaris, ebony, water chestnut, eggplant and mussel have anticancer effects; Almond, seaweed, kelp, coix seed, lily, gourd, grapefruit and radish can all inhibit the growth of cancer cells. Under the guidance of doctors, patients can choose the corresponding food for self-regulation according to their own system and physical condition, so as to improve their immunity and inhibit the recurrence and metastasis of tumors. 3, exercise and health care Sun Simiao, a famous doctor in the Tang Dynasty, once said: People are diligent in physical work, and all diseases cannot be reached. Hua Tuo, an imperial doctor, once compiled a five-bird play, imitating the movements of tigers, deer, bears, apes and birds in order to strengthen the body and prevent diseases. With the popularization of health care knowledge, people pay more and more attention to exercise, especially for cancer patients. Proper exercise can adjust the excitement and inhibition of the central nervous system accordingly, thus improving the quality of life of cancer patients. Exercise is not only physical exercise, but also the exercise of will and perseverance. Generally speaking, you should choose slow, soft, muscular and relaxed sports, such as walking, Tai Ji Chuan and jogging. And you can also choose to do some exercises such as expanding your chest, stretching your waist and raising your head. If you can't go to the gym for health reasons, you can also do some running and jumping, broadcasting and other sports in the courtyard, indoors and corridor. It is advisable not to feel tired after each exercise. Pulse and heartbeat frequency are often used as indicators of exercise. If you do a lot of exercise, your heart rate and pulse rate will be faster. Generally, it is advisable to increase the heart rate per minute to 120~ 140 beats per minute. If you have loss of appetite, dizziness, headache, fatigue, sweating and listlessness after exercise, it means that the exercise is too large and exceeds the endurance limit of your body, which will damage your body due to overwork. Everyone should choose suitable exercise according to their hobbies and physical condition, so as to achieve the purpose of physical exercise and health preservation. In short, if tumor patients can follow the theory and method of TCM health care during the recovery period, pay attention to emotional stability, the harmony of five flavors, the laws of daily life and proper physical exercise, they can achieve mental pleasure, smooth qi and blood, intensive acupuncture, soft meridians, flexible flexion and extension, strong bones and a balance of yin and yang, thus improving immune function, enhancing patients' self-control and adjustment ability, playing a good role in health care and improving quality of life.
