Using partial least squares discriminant analysis (PLS-DA), 26 and 34 characteristic resonances were found respectively in urine and plasma of ovariectomized rats (Variable importance, VIP value \u22651.0), and the significant altered metabolites identified in the plasma and urine were 10 and 9, respectively. Changes in these metabolites were related to the pathways of lipid, energy and amino acid metabolism, some of which involved the oxidative system. The described method was also used to analyze the therapeutic effects of Er-Xian Decoction (EXD), a traditional Chinese medicine widely used in the clinical treatment of osteoporosis in China. The results showed that EXD administration could provide satisfactory effects on osteoporosis through partially regulating the perturbed pathways of lipid, energy and amino acid metabolism and improving the anti-oxidative ability.<\/jats:p>","DOI":"10.3390\/ijms12117635","type":"journal-article","created":{"date-parts":[[2011,11,8]],"date-time":"2011-11-08T11:36:19Z","timestamp":1320752179000},"page":"7635-7651","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":47,"title":["A 1HNMR-Based Metabonomics Study of Postmenopausal Osteoporosis and Intervention Effects of Er-Xian Decoction in Ovariectomized Rats"],"prefix":"10.3390","volume":"12","author":[{"given":"Liming","family":"Xue","sequence":"first","affiliation":[{"name":"School of Pharmacy, Second Military Medical University, No. 325 Guohe Road, Shanghai 200433, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yin","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Pharmaceutics, No. 455 Hospital of CPLA, Shanghai 200052, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lei","family":"Liu","sequence":"additional","affiliation":[{"name":"School of Pharmacy, Second Military Medical University, No. 325 Guohe Road, Shanghai 200433, China"},{"name":"Department of Pharmacy, Fujian University of Traditional Chinese Medicine, Fuzhou 350108, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lu","family":"Zhao","sequence":"additional","affiliation":[{"name":"School of Pharmacy, Second Military Medical University, No. 325 Guohe Road, Shanghai 200433, China"},{"name":"Department of Pharmacy, Fujian University of Traditional Chinese Medicine, Fuzhou 350108, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ting","family":"Han","sequence":"additional","affiliation":[{"name":"School of Pharmacy, Second Military Medical University, No. 325 Guohe Road, Shanghai 200433, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qiaoyan","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Pharmacy, Second Military Medical University, No. 325 Guohe Road, Shanghai 200433, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Luping","family":"Qin","sequence":"additional","affiliation":[{"name":"School of Pharmacy, Second Military Medical University, No. 325 Guohe Road, Shanghai 200433, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2011,11,8]]},"reference":[{"key":"ref_1","first-page":"213","article-title":"Selective estrogen receptor modulators in treatment of postmenopausal osteoporosis","volume":"80","author":"Blazej","year":"2009","journal-title":"Ginekol.
