Objective To systematically assess the clinical efficacy of estrogen combined with antidepressants in the treatment of perimenopause-related depression in our country by meta analysis.Methods The electronic databases of CBMdisc,CNKI,VIP,Wanfang,PubMed,Cochrane Library and Google Scholar were retrieved by computer.The subject terms were set for retrieving the literatures on the effect evaluation of estrogen combined with antidepressants in treating perimenopause-related depression in our country published at home and abroad from January 1980 to February 2016.The study data and results of included literatures were performed the meta analysis by using the RevMan 5.1 software.Results Fifteen articles conforming to the inclusion standard were included.The data merged results showed that compared with single estrogen use group,in the aspects of the effective rate(RR=1.46,95%CI=1.29-1.66,P<0.004),HAMD score(WMD=-4.61,95%CI=-5.63——3.59,P<0.01)and KMI score(WMD=-5.83,95%CI=-11.12——0.53,P<0.01),the estrogen combined with antidepressants group had statistically significant difference.Conclusion The treatment and alleviating effect of estrogen substitution therapy combined with antidepressants for treating perimenopause symptoms and depression is superior to that of single estrogen use substitution therapy.

Objective To investigate the biosynthesis of arbutin by suspension culture of crown gall of transgenic Panax quinquefolium. Methods Hydroquinone in methanol(60 mg/mL) was added to the medium of the crown gall of P.quinquefolium after precultured for 20 d,then they were co-cultured for another 60 h.The product was isolated and purified by column chromatography and its structure was identified by physicochemical properties and spectroscopic data.The dynamic curve of biotransformation was investigated by quantative analysis of arbutin with HPLC.Results The product could be obtained from both of the culture and medium,which was isolated and elucidated as 4-hydroxyphenyl-?-D-glucopyranoside(arbutin).After co-cultured for 60 h,the mole conversion ratio of hydroquinone is 88.4%,the product contents in culture and medium are 63.69 mg/flask and 1.86 mg/flask,respectively,and the excretion ratio of arbutin reaches the highest(2.92%).Conclusion It's the first time around the world that the crown gall of transgenic P.quinquefolium is used as a biotransformation system and arbutin which shows varied pharmacological activites have been got successfully.
