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.

Objective To explore the etiopathogenisis of Reinke's edema. Methods To detect 15 samples of Reinke's edema of vocal cord mucosal and 5 samples of common vocal cord mucosal with S-P immunohistochemical method. Then to observe the effect of immunity class under the light microscope. To detect the expression of the VEGF and the production of the blood capillary in the sample of Reinke's edema of vocal cord mucosal with immunohisto-chemical method. Results There are 12 effects of sex in the 15 samples of Reinke's edema of vocal cord mucosal. There are effects of feminine in the 5 samples of common. Conclusion The main etiopathogenisis of Reinke's edema is that blood vessel grew ad libitum, the permeability of blood vessel increase and oxygen lack partly.

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
