Fig. 1From: LIPUS inhibits inflammation and catabolism through the NF‐κB pathway in human degenerative nucleus pulposus cellsLIPUS inhibits the production and gene expression of the inflammatory factors TNF-α and IL‐1β in LPS‐induced human NP cells. a The protein expression of TNF-α and IL‐1β was measured by ELISA. b The mRNA expression of TNF-α and IL‐1β was measured by RT-PCR. The results are presented the means ± SD. *P < 0.05Back to article page
