Résumé
To propose the new concept of multidimensional omics, and define that the multidimensional omics is a proper method for studying the material base and mechanism of traditional Chinese medicine (TCM) compounds. Zhuanggu Zhitong capsule was taken for example to study its effect against experimental postmenopausal osteoporosis. From the perspective of chemi-omics, genomics and proteomics of TCM, it systematically interpreted the efficacious materials and mechanisms of Zhuanggu Zhitong capsule in preventing and treating experimental postmenopausal osteoporosis, while taking the lead in designing a three dimensional form to intuitively exhibit the results of the multidimensional omics study. This study provides a new idea and solution for studies on the efficacious materials and mechanisms of TCM compounds.

<p><b>OBJECTIVE</b>To observe the effect of psoralidine in rats with ovariectomy, and preliminarily study its mechanism.</p><p><b>METHOD</b>Sixty female Sprague-Dawley rats were divided into 5 groups: the sham operation group, the model group, the psoralidine low-dose group (4 mg x kg(-1)), the psoralidine high-dose group (16 mg x kg(-1)) and the Zhuangguzhitong capsule group, with 12 rats in each group. Thirteen weeks later, their blood and bone samples were collected to detect bone density, bone biochemistry, pathomorphology, serum E2 and CT.</p><p><b>RESULT</b>Psoralidine could up-regulate the bone density of lumbar vertebra and thighbone of rats with ovariectomy (P < 0.05), the maximum bending strength of thighbone (P < 0.05), and serum E2 and CT (P < 0.05).</p><p><b>CONCLUSION</b>Psoralidine has a good active effect on postmenopausal antiosteoporosis. Its mechanism may be related to such pathways as E2 and CT.</p>
