RESUMO
Chronic migraine is one of neurological disorders with high rate of disability, but sufficient attention has not been paid in this field. A large number of clinical studies have shown traditional Chinese acupuncture is a kind of effective treatment with less side effects. Through the analysis of literature regarding acupuncture and migraine published from 1981 to 2017 in CNKI and PubMed databases, the mechanism of neural plasticity of acupuncture on chronic migraine was explored. It was believed the progress of chronic migraine involved the changes of neural plasticity in neural structure and function, and the neural plasticity related with neural sensitization during the process of chronic migraine was discussed from three aspects of electrophysiology, molecular chemistry and radiography. Acupuncture could treat and prevent chronic migraine via the mechanism of neural plasticity, but there was no related literature, hindering the further spreading and development of acupuncture for chronic migraine.
RESUMO
Waste plastics in the environment is called"gray pollution"as a result of difficult degradation and when dis-posed by incineration,secondary pollutants are released.In this paper the formation mechanism and path of some persistent or-ganic pollutants in the process of waste plastic incineration disposal and their potential hazards to the ecological system,even to human beings are briefly reviewed,and valuable references and suggestions are given.Some of effective measures which should be taken to inhibit the formation of these toxic organic compounds during waste disposal and reduce their negative effect on mankind.
RESUMO
Amphibian is playing a very important role in the field of environmental toxicological studies. In the present paper, taking the Xenopus laevis, a model animal of amphibian, as an example, reviewed the application of amphibian in environmental toxicology, such as acute toxicity, frog embryo teraogenesis array-Xenopus(FETAX), micronucleus test, environmental endocrine disruptors detection.
