Encourage patients to eat low-fat, high-protein, high-calorie, high-vitamin, easy-to-digest foods, supplement electrolytes such as potassium, calcium and magnesium, essential amino acids and energy supplements, and avoid spicy and other stimulating foods, tobacco and alcohol. Avoid spicy and other stimulating foods, tobacco and alcohol. Eat less sweets and fats. After the infusion, patients were asked to continue to rest in bed, and to observe the changes in body temperature and allergic symptoms. Most patients tolerated it and did not need special treatment. The body temperature subsided on its own, and a small number of patients returned to normal after symptomatic treatment. Very few patients with rapid heartbeat and shortness of breath after cell reinfusion should be stopped immediately and treated symptomatically. The remaining cell suspension should be sent back to the culture room for bacterial culture. Patients with adverse reactions such as chills, panic and chest tightness should stop the infusion immediately and report to the physician for prompt treatment, and save the remaining DC-CIK cell suspension and send it back to the laboratory for testing and bacterial culture to find the cause. Second, the integrated treatment of radiofrequency, chemotherapy three, complication management CIK cell therapy is a biological therapy, the side effects are not obvious, as long as the operation in strict accordance with GMP standards, according to its clinical indications for patient selection, its clinical application is safe and reliable. 1, biologic infusion reactions: according to the general biologic infusion reactions for treatment. 2, induced serious autoimmune disease: to methylprednisolone, calcium 5-TH receptor blockers, gammaglobulin, gastric acid inhibitors and gastric mucosal protectors, prevention of gastrointestinal bleeding, and symptomatic supportive therapy. At the same time, health care workers should do the following nursing work: general nursing care, psychological care Monitoring blood sugar Electrolytes and fecal occult blood test Preventing water-electrolyte disorders and calcium loss, avoiding the use of diuretics. 3, allergic reactions: treated as allergic reactions to blood products. 4, fever: treated as fever of blood products. 5, elevated tumor markers: immunotherapy may appear in the early stage of transient tumor marker elevation, no special treatment is required. 6, myelosuppression CIK cells have little effect on normal myeloid clonogenesis, only the production of red lineage shows mild inhibition, which may be related to CIK cells themselves secrete higher levels of IFN-r This may be related to the CIK cells themselves secrete higher levels of IFN-r. The small amount of peripheral blood collected from the patient’s single nucleated cells are mainly lymphocytes, because the proliferative capacity of the bone marrow is very strong, the loss of a small number of blood cells, can quickly be released from the bone marrow to replenish the blood.
