ABSTRACT
As a physical method, electromagnetic therapy has been widely used in clinical treatment of various human diseases. In this paper, a total of 123 research papers related to the clinical application of electromagnetic therapy were retrieved from the Chinese Journal Full-text Database also known as China National Knowledge Infrastructure (CNKI), WANFANG Database, Chinese Science and Technology Journal Database (CSTJ), PubMed, Europe PMC, etc. All papers were analyzed and evaluated, and 58 effective articles were selected. The clinical application and therapeutic effects of electromagnetic therapy on several diseases were reviewed, including hypertension, diabetes, insomnia, depression and osteoporosis. The categories of commonly used electromagnetic therapy were sorted out and summarized, including magnetization at acupoints, pulsed electromagnetic fields, gyromagnetic, repetitive transcranial magnetic stimulation, and wearing magnetic items. The results show that electromagnetic therapy has a wide range of applications and small side effects, it has significant effects on some medical diseases, neurological diseases, and orthopedic diseases.
ABSTRACT
Chemotherapy is one of the traditional tumors treatment solutions.Chemotherapy has the feature of tissue non-specificity,which can cause side effects on normal cells while inhibiting tumor cell growth.Magnetic targeting drug delivery system (MTDDS) employs biocompatible and stable magnetic nanoparticles (MNP) as drug carries to transport and accumulate anticancer drugs to the specific tumor tissues under the guidance of external magnetic field.This technology not only improves the efficiency of drug delivery and antitumor activity,but also reduces the drug dosage and side effects.The properties of drug-loaded MNPs and the applied external magnetic field are the main factors that affecting the MNPs targeting to the tumor tissues.The effectiveness of the targeted delivery of the drug-loaded magnetic nanoparticles mainly depends on the form and strength of the magnetic field at the target site.That is,whether there is sufficient strength to attract and retain NMPs,and to promote antitumor drug release at the tumor region.In this paper,the research progress of static magnetic field targeting drug delivery system in tumor diagnosis and therapy was summarized,which can provide some basic information for the relative scientific researches.
