Abstract:
Objective:To explore Lijin Zhenggu Therapy combined with heat supplementing needles on cartilage damage, immune balance, and liver X receptor NF-κB in knee osteoarthritis of New Zealand white rabbits.Methods:Totally 60 New Zealand white rabbits were divided into normal group, model group, Lijin Zhenggu Therapy group, heat supplementing needles group, and a combination group using random number table method, with 12 rabbits in each group. Except for the normal group, all other groups were established with knee osteoarthritis models. The Lijin Zhenggu Therapy group was treated with Lijin Zhenggu Therapy, the heat supplementing needles group was treated with heat supplementing needles, the combination group was treated with Lijin Zhenggu Therapy combined with heat supplementing needles. The pain threshold of each group of white rabbits was observed using a pain meter; HE staining was used to observe the morphology of cartilage damage in each group of white rabbits; ELISA was used to detect PGE 2, IL-1β and β-EP in the articular cartilage tissue of white rabbits in each group; PCR was used to detect the levels of LXRα and NF-κB mRNA. Western blot was used to detect toll like receptor 4 (TLR4), myeloid differentiation factor (MyD88), interferon regulatory factor-7 (IRF-7) in synovial tissue of rabbits in each group. Results:Compared with model group, the pain threshold of rabbits in heat supplementing needles group, Lijin Zhenggu Therapy group and combination group increased ( P<0.05); the levels of PGE 2 and IL-1β decreased ( P<0.05), while the level of β-EP increased ( P<0.05). LXRα mRNA level increased ( P<0.05), and NF-κB mRNA level decreased ( P<0.05); the expressions of TLR4, MyD88, IRF-7 and NF-κB P65 in synovial tissue decreased ( P<0.05). Conclusions:Lijin Zhenggu Therapy combined with heat supplementing needles can reduce the levels of PGE 2 and IL-1β, increase β-EP level, improve pain and cartilage tissue morphology. The mechanism may be related to the regulation of liver X receptor nuclear factor NF-κB pathway, reduction of inflammatory reactions and immunity maintaining.
