Effects of Angelicae Pubescentis and Loranthi Decotion on repairing knee joint cartilages in rats.

ABSTRACT: BACKGROUND:Knee osteoarthritis (KOA) is a common orthopedics disease and its pathological changes at early stage are the damage and loss of articular cartilage. Traditional Chinese medicine (TCM) prescription contains multiple components and has the unique advantages of the diversity of targets.We compared the traditional Chinese medical formulae (Angelicae Pubescentis and Loranthi decotion, APLD, or Duhuo Jisheng) with a western medicine (glucosamine sulfate, GS) to treat the rat arthritis models, and tracked the outcomes. METHODS:Thirty-two Wistar rats (weight 180?±?10 g, 6-week-old) were randomly divided into four groups (eight for each): group A as normal control group (no surgery and no drug treatment), group B as SIA (surgery-induced arthritis) model control without drug treatment, group C as SIA model + APLD, and group D as SIA model + GS. Anterior cruciate ligament in the knee joint of both hind legs from each rat in groups B, C, and D was shown and cut off to establish the SIA model. After 6 weeks of the surgery, rats in group C or D were treated with APLD or GS, respectively, for 8 weeks. Bone X-ray examination, histological images, and determination of genes of collagen II and aggrecan were performed. At week 14, both knee joint gap and bone structure disappeared in rats of group B, but they were visible in rats of groups A, C, and D. RESULTS:Histological images revealed that the structure and composition of the knee joint cartilage were significantly degenerated in group B and improved in group C. Genes of collagen II and aggrecan were significantly increased in both group C and D. CONCLUSION:APLD or GS gavage treatment for knee osteoarthritis (KOA) rat models was effective on the proliferation of cartilage chondrocytes and the damaged knee joint tissue repairing, and the APLD showed slightly superior in general.

Project description:BackgroundThe mechanism of action of Angelicae Pubescentis Radix in rheumatoid arthritis treatment is complex; the pathways and protein targets involved remain unclear. This study predicted the targets and signaling pathways of Angelicae Pubescentis Radix for rheumatoid arthritis treatment using network pharmacology and molecular docking technology and clarified its mechanism of action using in vitro cellular experiments.MethodsAngelicae Pubescentis Radix active components and related targets were retrieved from the traditional Chinese medicine systems pharmacology database. All human proteins were mined from the global protein database, and the network of active components and targets of Angelicae Pubescentis Radix was drawn using Cytoscape 3.7.1. GeneCard, Online Mendelian Inheritance in Man, and DrugBank databases were used to mine rheumatoid arthritis-related genes. Metascape was used for Gene Ontology function analysis and Kyoto Encyclopedia of Genes and Genomes enrichment pathways. β-sitosterol's molecular docking was determined using AutoDock Tools; pathway verification was performed in the Kyoto Encyclopedia of Genes and Genomes database, and the verified genes were input into the Human Protein Atlas database to observe the expression levels in various human body tissues.ResultsEight main active components were screened out of Angelicae Pubescentis Radix from the traditional Chinese medicine systems pharmacology database, and 60 targets related to major active ingredients were obtained. Forty-two core pathogenic rheumatoid arthritis-related genes were screened from GeneCard and other related databases. The enrichment of the Kyoto Encyclopedia of Genes and Genomes pathway included the vascular endothelial growth factor signaling pathway that proved to be the decisive pathway for rheumatoid arthritis treatment by a high degree value. In vitro experiments confirmed that Angelicae Pubescentis Radix mainly regulated cell proliferation and survival through the vascular endothelial growth factor signaling pathway and showed significant therapeutic effects on rheumatoid arthritis. The prostaglandin endoperoxide synthase 2 gene was associated with rheumatoid arthritis via pathway verification and monitoring of human gene expression levels.ConclusionsThe mechanism of the multi-component, multi-target, and multi-channel treatment of rheumatoid arthritis via Angelicae Pubescentis Radix was explored using network pharmacology and molecular docking technology, providing new thinking and research directions for future rheumatoid arthritis treatment using Angelicae Pubescentis Radix.
