This paper reviewed the studies on the effect of electroacupuncture in improving learning and memory functions in the past 10 years. It showed an overview of the mechanisms that how acupuncture worksed: promoting synaptic plasticity, regulation of microvascular injury and oxidative stress; slowing down the progress of brain cell apoptosis, inhibition of inflammatory response;regulating neurotransmitter release and protecting the ultrastructure of neurons. In addition, this paper puts forth the problems which left in the current studies.
ABSTRACT
Objective To research the expression and biological significance of methallothionein(MT) in different thyroid diseases(TDs).Methods The expression of MT was observed by immunohistochemical stain and the difference among TDs was compared.Results MT was completely expressed in all TDs. Expression of MT was 87.60?9.20 in thyroid carcinoma,significantly higher than that(62.20?12.40) in thyroid adenoma, that(61.10?13.20) in Graves′ disease and that(58.50?10.60) in Hashimoto′ thyroiditis (P
