China Pharmacy 2017;28(13):1736-1739
OBJECTIVE:To provide reference for the effective integration of standardization strategy of traditional Chinese medicine (TCM) and intellectual property. METHODS:Through analyzing the conflict between standardization requirement of TCM and intellectual property system,the coordination between TCM standards and intellectual property especially the trade secret rights was explored. RESULTS:The information disclosure of TCM standards and intellectual property strategy especially protec-tion of TCM trade secrets faced confrontation and conflict in system and design. For the suggestions to solve it,one is to reconfirm the role and positioning of the government on the adaption of standardization in public law field;another is to establish coordina-tion principle of information disclosure and confidentiality in private law field,and achieve difference open and moderate open of information. CONCLUSIONS:The TCM standardization is not absolute,the pros and cons is the precondition to solve the conflict between the standardization strategy and trade secret system in TCM in terms of protection of information freedom and secret infor-mation.

Objective To established the method of increasihg the proportion of T regulatory cells(Tr) to T effector cells(Te), which could suppresses allogeneic ahtigen reaction, by in vivo of glucocorti-coid (dexamethasone, DXM) combined with IL-2. Methods After combined treatment to male C57BL/6N mice (donor) with DXM(5 mg. kg-1· d-1 ) and IL-2 (300 000 IU · mouse-1·d-1) for 3 d, spleen mono-nuclear cells were made and were carried out by flow cytometry analysis. Using the spleen cells of BALB/c mice as aliogeneic antigen to stimulate the spleen cells of male C57BL/6N mice for 7 d after combined treat-ment of glucoeorticoid and IL-2, the reaction of cell proliferation was detected. Results After the treatrment of DXM and IL-2, CD4+ CD25+ Foxp3+ Tr cells in the spleen of C57BL/6N mice increased abviously. The ratio of CD25+ Foxp3+ Tr to CD4+ T cells was 24.22%±7.60% in the group of DXM combined with IL-2, while the control group was 4.02% ±0. 84% ( P =0. 01 ). Compared with the control group (0. 14±0.01 ), the ratio of Tr to Te increased obviously in the group of DXM combined with IL-2 (0.43±0. 15 ) ( P = 0.01 ). The group of DXM combined with IL-2 also expressed more glucocorticoid-induced tumor necrosis factor receptor(GITR) and alloreaction was suppressed/n vitro obviously ( P < 0. 05 ). Conclusion DXM amplifies IL-2 induced the proportion of Tr to Te, and suppresses the cell proliferation stimulated by alloge-neic antigen.
