文题释义:
腰突颗粒:系临床经验方,具有较好的临床效果,由独活、桑寄生、牛膝、杜仲、熟地黄、川芎、当归、芍药、茯苓、甘草、地龙、土鳖、蜈蚣、三棱、莪术组成,诸药合用,是为标本兼顾,扶正祛邪之剂。
人髓核细胞:髓核是乳白色半透明胶状体,富于弹性,为椎间盘结构的一部分,位于两软骨终板与纤维环之间。发育成熟的髓核是一个由软骨样细胞分散在细胞间质内,周围围绕着一个比较致密的胶原纤维网的含水球。髓核细胞即其中类软骨样细胞。
摘要
背景:
核因子κB在退变椎间盘中呈高表达,经验方腰突颗粒治疗腰椎间盘突出症临床效果良好,通过核因子κB信号通路试探讨其治疗作用的机制。
目的:探讨腰突颗粒含药血清对人髓核细胞核因子κB信号转导通路的影响。
方法:将8只新西兰大白兔随机等分为生理盐水组和低、中、高剂量组,分别以生理盐水及10,20,40 mL腰突颗粒水煎剂灌胃7 d。于最后一次灌胃2 h后颈总动脉采血,收集血清,分别配成体积分数10%含药血清的DMEM培养液保存备用,分别干预人髓核细胞24 h。
结果与结论:体积分数10%含药血清干预后,与生理盐水组相比,低剂量组、中剂量组、高剂量组人髓核细胞中白细胞介素8、肿瘤坏死因子α、p-P65、P50、IκB-α和IKK-β mRNA相对表达水平均降低,且细胞中p-P65、P50、IκB-α和IKK-β蛋白表达水平降低,同时随着灌服腰突颗粒剂量的增加,白细胞介素8、肿瘤坏死因子α、p-P65、P50、IκB-α和IKK-β mRNA相对表达水平逐渐降低,p-P65、P50、IκB-α和IKK-β蛋白表达水平降低。提示腰突颗粒含药血清能阻断人髓核细胞中核因子κB信号转导通路,进而减缓髓核细胞的退变,起到保护人髓核细胞的作用。

Abstract:

BACKGROUND: Nuclear factor-κB (NF-κB) is highly expressed in the degenerated intervertebral disc. The Herbal Compound formula Yaotu Granules for lumbar disc herniation has achieved good clinical results; however, the underlying mechanisms remain poorly understood.
OBJECTIVE: To explore mechanisms underlying the effects of the drug serum of Yaotu Granules on NF-κB signaling pathway.
METHODS: Eight New Zealand white rabbits were randomly divided into normal saline group, low-, middle-, and high-dose drug groups. Normal saline, 10, 20, and 40 mL of water decoction of Yaotu Granules were administered intragastrically in the normal saline, low-, middle-, and high-dose drug groups for 7 days, respectively. The drug serum of Yaotu Granules was prepared using serum samples obtained from the common carotid artery at 2 hours after the last administration. Human nucleus pulposus cells were maintained in DMEM containing 10% (v/v) drug serum for 24 hours.
RESULTS AND CONCLUSION: The expression levels of interleukin (IL)-8, tumor necrosis factor (TNF)-α, p-P65, P50, IκB-α (the NF-κB inhibitor), and IκB kinase β (IKK-β) mRNA in human nucleus pulposus cells in three drug serum groups were significantly decreased compared with the normal saline group; in addition, a similar change in the expression levels of p-P65, P50, IκB-α, and IKK-β protein between groups were detected. Noticeably, the expression levels of IL-8, TNF-α, p-P65, P50, IκB-α, and IKK-β mRNA, as well as the expression levels of p-P65, P50, IκB-α, and IKK-β protein were gradually decreased with the increased drug dose. All these results suggest that the drug serum of Yaotu Granules can protect nucleus pulposus cells and delay their degeneration through blocking NF-κB signaling pathway.
