The results of character evolution history reconstruction shows the SC in PT and AD clade might be a homoplasy character; also, the SC in PT clade might have multiple origins. SC in Pteridaceae has some special characteristics:(1) the cell long axes usually run parallel to the lateral veins;(2) Most of Pteris and Adianum species have VSC only in lower epidermis;(3) Species have ISC also have VSC.(4) Presence of spicular cells is highly correlated with the long veinal epidermal cells. Species have type III silica deposition type usually have longer and narrower veinal epidermal cell compared with ordinary epidermal cells; Species have type IV silica deposition type also have long epidermal cells, but not significantly different from ordinary epidermal cells.

Mitochondria was relatively little in size. Round primary lysosome with high electron-densed granules and secondary lysosome with high or low electron-densed granules were seen frequently. DCs contained many rough endoplasmic reticulum, the Golgi apparatus and ribosomes. The vacuoles with flocculent electron-densed granules were rare. Some special granules in cytoplasm were seen, whose surface like earphone were covered with a membrane. High electron-densed contents in the granules were near one side and the other side was bright. The nucleus became markedly small in volume, nephroid or hoofed in shape. The nucleus had little euchromatin and lots of heterochromatin under nuclear membrane.

From 94 soil samples and 9 bark samples in these areas, 259 Myxobacteria strains were isolated and 140 strains of them were purified. These 259 Myxobacteria strains were primarily identified in genus or species level by their fruiting bodies, myxospores and vegetative cells on the base of Sergey's manual of determinative bacteriology and they belonged to 9 genera(Myxococcus, Corallococcm. Angiococcus. Archangium, Cystobacter. Stigmatella . Hapoangium. Nannocystis. Polyangium) of Myxococcales.

CGRP content in myocardium gradually enhanced from normal group to controls group, and model group's was the highest. We found immunopositive neurons and nerve fibers of nNOS and CGRP by immunochemistry in normal myocardium. They were mainly round-shaped and oval-shaped, also tadpole-shaped、 shuttle-shaped、triangle-shaped、ring-shaped and irregular-shaped. Nv of neurons and nerve fibers in atria were more than in ventricle in some degree; Those in right part of heart were more than in left. Morphology of CGRP neurons changed in model group, the number of ring-shaped neurons increasing, while the round-shaped and oval-shaped decreasing, and Nv and Sv of model group were markedly less than normal. Expression of nNOS mRNA was overly higher than normal group, but CGRP was opposite.
