Nuclear medicine nuclide therapy is the introduction of radioactive drugs into the human body by oral or injection, these drugs into the human body, will be with the blood flow, targeting gradually gathered in the whole body at the foci of the disease (similar to a missile-like), and then use its emission of short-range rays to kill the diseased cells, to achieve the purpose of treatment of disease. At present, nuclide treatment of diseases has reached dozens of: 1, 131 iodine treatment of hyperthyroidism; 2, 131 iodine treatment of thyroid cancer; 3, 89Sr (strontium) treatment of tumor bone metastasis; 4, 131 iodine-functional autonomic thyroid adenoma treatment 5, Yunknen treatment of rheumatoid arthritis, hyperthyroidism with infiltrating proptosis, ankylosing spondylitis, psoriasis and psoriatic arthritis. It can inhibit cancer bone metastasis, have analgesic effect on cancer bone metastasis, prevent and treat osteoporosis, prevent bone fracture, frozen shoulder, gout, rheumatoid arthritis and other bone and joint diseases. 6.90SR (strontium) dressing treatment of hemangioma, old scars, bad breath, etc.; nuclide therapy is fundamentally different from conventional chemotherapy or radiotherapy, firstly, it is the use of nuclear rays to treat the disease; secondly, the drugs of nuclide therapy are selective to the diseased tissues, and will be gathered in the foci; thirdly, the effect of nuclide therapy is relatively long-lasting; fourthly, it is a safe and simple method. Nuclide therapy can be used in conjunction with chemotherapy, radiotherapy and surgery.
