摘　　要：OBJECTIVE: To explore the multi-component synergistic mechanism of Zuogui Wan(左归丸, ZGW) in treating postmenopausal osteoporosis(PMOP). METHODS: The main components and target genes of ZGW were screened via the Traditional Chinese Medicine Systems Pharmacology(TCMSP). In addition, the target gene sets of PMOP were derived from the Gene Cards and Online Mendelian Inheritance in Man databases. The search tool for recurring instances of neighbouring genes(STRING) 11.0 software was used to analyze the interaction among intersecting genes. Cytoscape 3.6.1 software and the Matthews correlation coefficient(MCC) algorithm were used to screen the core genes. Fifty Sprague-Dawley female rats were randomly divided into the sham-operated(Sham) group and the four ovariectomized(OVX) subgroups. Rats subjected to Sham or OVX were administered with the vehicle(OVX, 1 m L water/100 g weight), 17β-estradiol(E2, 50 μg·kg-1·d-1), and lyophilized powder of ZGW at a low dose of 2.3(ZGW-L) and high dose of 4.6(ZGW-H) g·kg-1·d-1 for three months. The bone density and bone strength were assessed using dual-energy X-ray and three-point bending tests, respectively. Furthermore, enzyme-linked immunosorbent assay, Hematoxylin-eosin staining, and western blot analysis were used to determine the potential pharmacological mechanisms of action of ZGW in PMOP. RESULTS: A total of 117 active compounds of ZGW were screened from the TCMSP. Furthermore, 108 intersecting genes of drugs and diseases were identified. Using STRING software and the MCC algorithm, ten core genes, including C-X-C chemokine living 8(CXCL8), C-C chemokine receptor type 2(CCR2), alpha-2a active receptor(ADRA2A), melatonin receptor type 1B(MTNR1B), and amyloid-beta A4 protein(APP), were identified. The anti-osteoporosis regulation network of ZGW was constructed using the Cytoscape software. The animal experiments demonstrated that ZGW groups significantly reduced the serum levels of β-C-terminal telopeptide of type I collagen(β-CTX) and increased serum levels of bo
