Network pharmacology and experimental validation to reveal the pharmacological mechanisms of Astragaloside Ⅳ in treating intervertebral disc degeneration.

This study aims to identify potential targets and regulatory mechanisms of Astragaloside Ⅳ (AS-Ⅳ) in treating intervertebral disc degeneration (IDD) through network pharmacology analysis with experimental validation. Lumbar spine instability (LSI) mouse models were first established and treated with AS-Ⅳ. Micro-CT, safranin O-fast green staining, IDD score, RT-PCR and immunohistochemistry staining were employed to demonstrate the effect of AS-Ⅳ.

[Preliminary study of TRPV4 affects chondrocyte degeneration].

Objective: To explore and verify that transient receptor potential vanilloid 4(TRPV4) affects chondrocyte degeneration.

Methods: Neonatal SD rats were selected, primary chondrocytes were extracted, and identified by toluidine blue staining and alcian blue staining;an in vitro chondrocyte inflammation model was constructed by IL-1β, and TRPV4 inhibitor was used to treat chondrocytes under inflammatory conditions, and the chondrocytes were treated by RT-PCR method was used to detect matrix metallopeptidase 13(MMP-13), a disintegrin and metalloproteinase with thrombospondin 5, (ADAMTS-5)、nitric oxide synthase 2(NOS2)、Collagen, type II alpha 1(Col2α1)and aggrecan (Acan) mRNA in chondrocytes; primary chondrocytes were treated with different concentrations of TRPV4 overexpression plasmid, and the optimal overexpression dose was screened. The mRNA expressions of TRPV4, MMP-13, ADAMTS-5, NOS2, Col2α1 and Acan in chondrocytes under the optimal TRPV4 overexpression dose were detected.

Efficacy of Combining Traditional Chinese Manual Therapy (Tuina) and Specific Therapeutic Neck Exercise in Young Adults with Non-Specific Chronic Neck Pain: Study Protocol for a Randomized Controlled Trial.

Purpose: Non-specific chronic neck pain (NSCNP) is an increasingly common musculoskeletal disease and an important issue in the global healthcare system. Some studies have shown that the combination of manual therapy and exercise is effective in treating NSCNP but still with several limitations. Traditional Chinese manual therapy (tuina) is a Chinese manual therapy that consists of soft tissue manipulation and spinal manipulation.

MicroRNAs and long non-coding RNAs in cartilage homeostasis and osteoarthritis.

During the last decade, osteoarthritis (OA) has become one of the most prevalent musculoskeletal diseases worldwide. OA is characterized by progressive loss of articular cartilage, abnormal remodeling of subchondral bone, hyperplasia of synovial cells, and growth of osteophytes, which lead to chronic pain and disability. The pathological mechanisms underlying OA initiation and progression are still poorly understood.

Pharmacological effects of higenamine based on signalling pathways and mechanism of action.

Higenamine (HG) is a chemical compound found in various plants, such as aconite. Recent pharmacological studies have demonstrated its effectiveness in the management of many diseases. Several mechanisms of action of HG have been proposed; however, they have not yet been classified.

Melittin Inhibits Growth of Human Osteosarcoma 143B Cells through Induction of Apoptosis Suppressing the Wnt/β-catenin Signaling Pathway.

Background And Purpose: Osteosarcoma is the most commonly seen type of primary malignant bone tumors in children and adolescents. Partial patients with osteosarcoma cannot tolerate the side effects of chemotherapy drugs. Hence, it is urgent to find anti-osteosarcoma drugs with low side effects.

To Explore the Mechanism of "Fuzi-Guizhi" for the Treatment of Osteoarthritis on the Basis of Network Pharmacology and Molecular Docking.

Objective: The objective of this study is to analyze and verify the main drug components and targets of "Fuzi-Guizhi" in the treatment of osteoarthritis by using the network pharmacology platform.

Methods: The integrated pharmacology of "Fuzi-Guizhi" was analyzed by using the platform of integrated pharmacology of traditional Chinese medicine to explore its mechanism in the treatment of osteoarthritis. By establishing an arthritis model in vitro, the pharmacological effect of "aconitecassia twigs" on articular cartilage was evaluated and conducted for molecular docking.

Efficacy of electroacupuncture in patients with failed back surgery syndrome: study protocol for a randomized controlled trial.

Background: Persistent pain following back surgery called failed back surgery syndrome remains a major treatment challenge. The aim of this study is to evaluate the efficacy and safety of electroacupuncture on relieving back pain in FBSS patients.

Methods/design: This is a randomized, single-blind, single-site, placebo-controlled trial.

Melittin inhibits lung metastasis of human osteosarcoma: Evidence of wnt/β-catenin signaling pathway participation.

Melittin is a major active peptide component of bee venom that has been demonstrated to show anti-tumor effects. Osteosarcoma is a type of bone tumor with a high degree of malignancy, and metastasis is the main challenge of osteosarcoma therapy. This study aimed to investigate the role of melittin in the lung metastasis of osteosarcoma.

Prognostic Significance of β-Catenin Expression in Osteosarcoma: A Meta-Analysis.

β-catenin plays a crucial role in the progression of osteosarcoma. However, the clinical significance of β-catenin over-expression in osteosarcoma still remains unclear. Thus, we performed a meta-analysis of studies that evaluated the impact of β-catenin on metastasis and overall survival (OS) in osteosarcoma.

Differential expression of AURKA/PLK4 in quiescence and senescence of osteosarcoma U2OS cells.

This study aimed to identify co-expressed differentially expressed genes (DEGs) in quiescence and senescence of osteosarcoma (OS) U2OS cells and investigate their biological functions. GSE94805 from Gene Expression Omnibus database was extracted, involving 12 samples of OS U2OS cells (4 quiescence, 4 senescence, and 4 control samples). After analysis of DEGs by limma package, VENN analysis was performed to identify co-expressed DEGs in quiescence and senescent.
