Studies were conducted on the effects of different fertilizer application on the development of periderm,depth of cortex and phleom,xylem depth and accumulation of active constituents like tanshinone ⅡA and salvianolic acid B.

The results showed that the root transactions had significant differences in periderm,phloem,and xylem between cultivated and wild Salvia miltiorrhiza.

The expression of CD13 and Collagen Ⅰ in pericytes of human granulation tissue;

Study on the correlation of helicobacter pylori infection with perioral dermatitis;

Effect analysis of erythromycin crem and thermal spring waters in the treatment of perioral dermatitis;

Flow cytometry was used to compare the apoptotic rate of fibroblasts derived from keloid and its surrounding skin, when it was cultured in serum-deprived medium for 24 hours or was induced by Fas antibody.

Due to some characteristics of keloids such as infiltrative growth, easy to recur after therapy and have thicker dermis in the surrounding skin of keloids, we have such a hypothesis that maybe there are abnormal fibroblasts in the surrounding .
