Study on mechanism of Bushen Culuan Formula in treatment of polycystic ovary syndrome based on network pharmacology and molecular docking / 中国中药杂志

This study used network pharmacology and molecular docking to study the mechanism of Bushen Culuan Formula in the treatment of infertility caused by polycystic ovary syndrome(PCOS). The active ingredients and potential drug targets of Bushen Cu-luan Decoction were obtained by searching the Traditional Chinese Medicine System Pharmacology(TCMSP) database, and the targets of PCOS by searching GeneCards. After the drug targets and disease targets were corrected by Uniprot, the intersection genes were obtained. STRING database and Cytoscape 3.7.2 were used for protein-protein interaction(PPI) analysis of the intersection genes. The ClueGO plug-in of Cytoscape 3.7.2 was employed to perform gene ontology(GO) enrichment and KEGG pathway enrichment for the intersection genes. Finally, molecular docking of the key active ingredients with the targets of Bushen Culuan Formula was performed using AutoDockVina and MGLtools. A total of 136 active ingredients and 314 drug targets of the decoction were obtained from TCMSP, and 136 disease targets from GeneCards. Finally, 49 drug-disease intersection genes were obtained. GO enrichment found that the genes were mainly involved in the regulation of muscle cell apoptosis, positive regulation of small molecule metabolism, core promoter binding, RNA polymerase Ⅱ regulation of pri-miRNA transcription, negative regulation of transmembrane transport and other biological functions. The enriched KEGG pathways mainly included MAPK, PI3 K-Akt, p53, and HIF-1 signaling pathways. The results of molecular docking showed that quercetin and PTGS2 can bind stably and interact through amino acid residues THR206, TRP387, ASN382, etc. This study preliminarily reveals the multi-component, multi-target, and multi-pathway mechanism of Bushen Culuan Formula in the treatment of PCOS-related infertility, which provides a basis for further research.

Effect of therapies for kidney-tonifying and blood-activating in treatment of anovulatory infertility in eugenics / 中国中药杂志

In the context of the new era, paying attention to maternal and child health and advocating prenatal and postnatal care can effectively improve the quality of the birth population. Traditional Chinese medicine has a long history of prenatal and postnatal healthcare with rich content, which is the theoretical basis of modern related services. With the social development and the improvement of people's awareness of prenatal and postnatal healthcare, people have gradually shifted the focus of prenatal and postnatal healthcare to the peri-pregnancy stage at present, namely that couples of childbearing age are guided to prepare for pregnancy under the premise of solving their basic diseases. Infertility is a common and refractory disease for women of childbearing age. Ovulation disorder is one of its common pathological mechanisms. Traditional Chinese medicine believes that kidney deficiency is the main cause and pa-thogenesis of anovulation infertility and blood stasis is an important factor throughout the disease course. In clinical practice, therapies for invigorating kidney and activating blood are safe and reliable to treat anovulatory infertility mainly by adjusting the hypothalamus-pituitary-ovarian axis, improving ovarian function, uterine environment and gamete quality and increasing endometrial volume. Under the guidance of the thought of prenatal and postnatal healthcare, the authors tried to explore the effect of therapies for kidney-tonifying and blood-activating in the treatment of anovulatory infertility in eugenics, with the purpose of providing ideas and basis for subsequent relevant clinical studies and contributing to prenatal and postnatal healthcare services.
