六味地黄丸对椎间盘体外退变模型椎间盘细胞外基质组分的影响
Effect of Liuwei Dihuang Pills on the extracellular matrix components of intervertebral disc degeneration models in vitro
摘要
Abstract
BACKGROUND: Liuwei Dihuang Pills (LWPs), a famous Chinese prescription for replenishing the liver and kidney, have achieved good effect in the treatment of backache. However, the mechanism underlying LWPs treating backache with kidney deficiency is unclear. OBJECTIVE: To observe the effect of LWPs on extracellular matrix components of rabbit intervertebral disc degeneration models in vitro, and to explore the effect of LWPs in the prevention and treatment of intervertebral disc degeneration.METHODS: Totally 100 L1-6 intervertebral discs with endplate removed from 20 New Zealand rabbits were randomly divided into control, tumor necrosis factor α (TNF-α), p38-JNK/SAPK blocked, LWPs, and combination groups (n=20 per group). 2 μL of 10 mg/L TNF-α, 10 μL of 20 μmol/L SB203580 (specific inhibitor of p38MAPK) and SP600125 (inhibitor of JNK), 10% LWPs serum, 10% LWPs combined with 2 μL of 10 mg/L TNF-α were added into the medium of the corresponding group. Samples were collected at 2, 4, 6 and 14 days of culture. RESULTS AND CONCLUSION: The addition of TNF-α significantly upregulated the mRNA and protein expression levels of collagen type I, while significantly downregulated the levels of glycosaminoglycan and hyaluronic acid, chondroitin sulfate/keratan sulfate ratio, as well as the protein and mRNA expression levels of proteoglycan and collagen type Ⅱ (P < 0.05). LWPs could partly reverse the changes caused by TNF-α, indicating that LWPs can alleviate intervertebral disc degeneration to a certain extent.关键词
