ABSTRACT
Perimenopausal syndrome affects women 's work and life. This paper summarized the recent clinical researches of perimenopausal in the fields of the etiology and pathogenesis including the balance of yin and yang and regulating the Chong and Ren meridian, the traditional Chinese medicine treatment of acupuncture and herbs, in order to show the advantages of Chinese medicine.
ABSTRACT
Objective To investigate the effect of tripterygium glycosides on the resistance to immune rejection after allogeneic islet transplantation in mice.Methods Twenty C57BL/6 mice were treated with STZ diabetes mellitus and transplanted the islets from Balb/c mice donor,then recipient mice were randomly divided into two groups:triptolide group and model control group(n=10),and were intraperitoneal injected with tripterygium glycoside solutin and equivalent solvent of 5 mg·kg-1·d-1 for 14 days.Blood glucose and body weight were measured within 4 weeks after transplantation.Two weeks later,two groups of grafted islets were stained by HE staining and immunohistochemical staining,the expression of IL-2 protein were detected by Western blotting.Results The level of blood glucose were decreased to normal in the triptolide group and model control group after islet transplantation,but blood glucose gradually increased in the model control group after two weeks.Compared with the model control group,the inflammatory cells were less infiltrated and the immunohistochemical staining of insulin was deeper in the triptolide group.The expression of IL-2 in the triptolide group was significantly decreased(P<0.05).Conclusion Tripterygium glucoside could significantly decrease the inflammatory cell infiltration and inflammation factor expression in the allogeneic islet recipients to reduce the immune rejection and improve graft survival.

ABSTRACT
OBJECTIVE: To study the effects of Azone,propylene glycol(PG),oleic acid(OA) alone or in combination of two or three as penetration enhancers on the in vitro transdermal efficacy of diclofenac potassium(DP) gels.METHODS: Thirteen formulations of DP gels containing the following different penetration enhancers at different concentrations were prepared: blank,3% Azone, 5% OA,12% PG,6% PG+2.5% OA,12% PG+5% OA,1.5% Azone+2.5% OA,1.5% Azone+6% PG+5% OA,1.5 % Azone+12% PG,3% Azone+5% OA,3% Azone+6% PG,3% Azone+6% PG+5% OA,and 3% Azone+12% PG.The in vitro permeation test was performed on a modified Franz-type diffusion cell with human skin as transdermal barrier taking transdermal velocity(J) as index to determine and compute the transdermal properties of the DP gels after treated respectively by the above 13 penetration enhancers.RESULTS: Compared with the blank control group,all the penetration enhancer-treated formulations showed significant higher J value,with the formulation treated by 3% Az-one+12% PG enhancer showing the highest J value of 10.253 0 ?g?cm-2?h-1.CONCLUSION: All the three penetration enhancers could promote the transdermal permeation DP gels,much as in the combination of Azone and propylene.
