Objective To study the reaction mechanism of ginsenosides in red ginseng processing. Methods The major constituents of ginsenosides were assigned by HPLC/MS/MS data. Ginsenosides (including protopanaxadiol, protopanaxatriol, and oleanolic acid type) of white ginseng and red ginseng were compared by HPLC/MS data. Results Ginsenosides were produced from esterolysis of corresponding malonyl ginsenosides in red ginseng processing. Another reaction of malonyl ginsenosides in red ginseng processing was decarboxylated to produce corresponding acetyl ginsenosides. Hydrolysis of glycosidic bond at C_(20) and isomerous reaction of C_(20) were the main reaction of dammarane type ginsenoside. High degree of esterolysis and glycosidic bond hydrolysis of oleanolic acid type ginsenosides all occurred during the red ginseng processing. Conclusion Great changes of ginsenosides have been obviously found in processing ginseng to red ginseng. Special constituents of red ginseng could be produced in ginseng processing.

When entering the clinical teaching phase,the last step before graduation and assignation,medical students are given more chances to contact with the society.This is an important period that the educators should care more about and communicate more with the students in order to foster their career mentality.Our suggestions are as follows,1.Emphasizing the clinical ability.The basic clinical skills are the premise and guarantee that a medical student is able to diagnose and cure,and also the main content of quality education and evaluation for medical students,2.Emphasizing the formation of the research-type learning habit and the innovative thinking modes.The cultivation of the research-type learning ability is a symbol of innovative talent,as well as an essential quality.An innovative thinking training consists of different thinking,converse-thinking,role-changing thinking,divergent thinking and critical thinking.3.Must correctly deal with the relationships between having a clinical training or preparing for the postgraduate entrance examination and getting a job.The educators should help the student form virtues of professional dedication,diligence and positive learning attitudes,strengthen their sense of social responsibility and obligation,and establish correct world outlook,outlook on life and values.4.Must enhance the nurturance of medical students' professional ethics.In the clinical practice,the students' behavior must be regulated.What's more,they should learn to be a qualified doctor who respect,be responsible for and care for the patients.
