The nurse took a strangely shaped device in her hand and slowly covered the young patient's face. The card-sized device flashed red hot, and the closer the device was, the less feared the patient was. He hopes that this painless phototherapy will help him alleviate the pain and discomfort of cancer treatment.
This young patient is undergoing a Phase 2 clinical trial. The first round of trials conducted by researchers at the University of Wisconsin Medical School in Milwaukee Children's Hospital was so effective that trials began in several US and foreign hospitals.
Dr. Harry Whelan, professor of neurology, pediatrics and hyperbaric oxygen therapy at the University of Wisconsin Medical School, said: "We have seen the use of LEDs to improve the quality of life of patients with bone marrow transplants. These trials will help us take the next step for this disease Standards for treatment. "
The light sources used are all from LEDs. They are used in hundreds of applications, from electronic clock displays to giant TV screens. Researchers have found that LEDs have broad application prospects in the medical field. Biologists have found that cells exposed to LED near-infrared light grow 150-200% faster than cells that are not stimulated by light. Light energy increases the energy in the cell and accelerates the healing process.
的 In the first phase of the study, LED was used to treat oral mucositis in children with bone marrow transplantation, and the results were significant. In many cases, young patients with bone marrow transplants develop ulcers in their mouths and throats, which can be intolerable and even intestinal inflammation. Chewing and swallowing become difficult, diets are reduced, and children's health is affected.
Dr. Whelan said: "The results of the first phase of the research are encouraging. The use of LED devices has greatly reduced or prevented the problem of oral mucositis, but we still need to conduct further research. We are conducting new clinical trials that will eventually make these devices approved And widely used. "
