中文摘要:
目的：探讨TLR4/NF-κB通路在大鼠膝骨关节炎（OA）滑膜早期病变的表达情况。
方法：将8周龄体重为（200±20）g的18只雄性SD大鼠按照随机数字表法分为模型组和对照组，每组9只。模型组按照改良Hulth法构建膝OA模型，对照组不做手术。分别于术后4、21 d提取滑膜组织和血清，采用PCR法检测CD14、TLR-4、IL-1β、TNF-α、MMP-13、ADAMTS-4表达；采用Western-blot法检测NF-κB p65蛋白表达；采用Elisa法检测血清中透明质酸（HA）及Ⅲ型前胶原氨基端（PⅢNP）浓度。
结果：术后4、21 d时模型组CD14、ADAMTS-4及NF-κB p65表达均较对照组升高，术后21 d时模型组TLR-4、Ⅱ-1β、TNF-α及MMP-13表达较对照组升高（P<0.01）。模型组术后4 d时血清PⅢNP和HA浓度高于对照组，术后21 d时两组比较差异无统计学意义。
结论：NF-κB通路可通过CD14/TLR-4早期激活进而触发滑膜分泌炎性因子IL-1β、TNF-a、MMP-13、ADAMTS-4，PⅢNP和HA增加介导膝OA发生。 |

ABSTRACT
Objective: To study role of TLR4/NF-κB pathway for early change of synovial membrane in knee osteoarthritis rats.
Methods: Eighteen male SD rats weighted (200±20) g were randomly divided into 2 groups,namely control and model group,and 9 in each group. Knee OA model group was established by using modified Hulth method in model group. Control group was not treated. Synovial tissue and serum was extracted at 4 and 21 d after operation. Expression of CD14,TLR4,IL-1β,TNF-α,ADAMTS-4,MMP-13 were detected by real-time PCR respectively. NF-κB p65 protein was detected by Western-blot;serum concentrations of haluronic acid (HA),N-propeptide of type Ⅲ procollagen(PⅢNP) was detected by Elisa.
Results: Expression of CD14,ADAMTS-4,and NF-κB p65 in model group were higher than that of control group at 4 and 21 days after operation,while expression of TLR4,IL-1β,TNF-α and MMP-13 were higher than that of control group at 21 days after operation(P<0.01). Concentration of PⅢNP and HA in model group were higher than that of control group at 4 days after operation,while there was no significant difference at 21 days after operation.
Conclusion: NF-κB pathway could mediate occurrence of KOA by early activating and triggeringg synovial increasingly secreting inflammatory secretion CD14,TLR4,IL-1β,TNF-α,ADAMTS-4,MMP-13,PⅢNP and HA. |
