ABSTRACT
AIM: To explore the mechanism of Ginkgo biloba in the treatment of steroid-induced osteonecrosis of the femoral head based on network pharmacology. METHODS: The active ingredients and targets of Ginkgo biloba were predicted by the TCMSP, ADME, and PharmMapper databases. The disease targets related to steroid-induced osteonecrosis of the femoral head were searched by the GeneCards and OMIM databases. Cytoscape 3.6.1 was used to construct a protein-protein interaction network. The core target analysis, modular analysis, GO enrichment analysis, and KEGG pathway analysis of the targets of Ginkgo biloba in the intervention of steroid-induced osteonecrosis of the femoral head were performed by the STRING database. RESULTS: In this study, a total of 16 active ingredients of Ginkgo biloba and 547 targets were screened, of which 133 targets were related to steroid-induced femoral head necrosis. By PPI network topology analysis, TP53, AKT1, IL6, VEGFA, MAPK1, JUN, MAPK8, EGFR, EGF, and MYC were identified as the core targets. GO modularization analysis showed that these core targets were mainly related to apoptosis and angiogenesis. GO enrichment analysis was used to analyze the biological processes, cellular localization, and molecular functions of the core targets. KEGG enrichment analysis showed that the targets were mainly involved in molecular signaling pathways, among which the PI3K/AKT signaling pathway was the most relevant. CONCLUSION: Ginkgo biloba can inhibit steroid-induced osteonecrosis of the femoral head through multiple components, targets, and pathways, which provides the theoretical basis and reference for subsequent cell and animal experiments.
ABSTRACT
Objective To study the application value of atorvastatin combined with anticoagulation drugs in the treatment of steroid-induced necrosis of the femoral head in the elderly.Methods From February 2013 to January 2016, 112 cases elderly patients accepted treatment of steroid-induced necrosis of the femoral head in our hospital were selected.They were divided into observation group and control group with 56 cases in each group randomly.The two groups were treated with anticoagulant therapy, the observation group received atorvastatin on the basis of control group.The efficacy and indicators between two groups after treatment were compared.Results The excellent and good rate was in observation group was 92.86%, which was higher than 66.07% in control group ( P <0.05 ) .The pain degree, walking ability and total joint mobility score of the observation group were significantly higher than those in the control group(P<0.05).After treatment, plasma viscosity and hematocrit of the observation group were significantly lower than the control group(P<0.05).The time of collapse of the femoral head and the index of necrosis of the observation group were significantly lower than the control group(P <0.05).Conclusion Atorvastatin combined with anticoagulant drugs in the treatment of elderly patients with steroid-induced femoral head necrosis has significant effect, could effectively improve the quality of life of patients with good safety, high application value.
