摘要
目的观察膝骨关节炎(KOA)患者尿Ⅱ型胶原C端肽(CTX-Ⅱ)及软骨寡聚基质蛋白(COMP)的表达变化,并探讨其与病情严重程度的相关性。方法选取2017年8月至2018年3月于南京医科大学附属明基医院被明确诊断为KOA的113例患者作为KOA组,Kellgren-Lawrence(K-L)分级:Ⅰ级27例,Ⅱ级34例,Ⅲ级27例,Ⅳ级25例。另外随机选取同期30名健康体检者作为对照组。通过酶联免疫吸附试验法检测所有受试者尿CTX-Ⅱ及COMP水平,并对检测结果进行分析、比较。结果 KOA组尿CTX-Ⅱ及COMP水平明显高于对照组(P <0. 05);KOA患者尿CTX-Ⅱ及COMP水平随K-L分级的增加而逐渐升高,且各K-L级别间尿CTX-Ⅱ及COMP水平比较差异有统计学意义(P <0. 05); KOA患者K-L分级与尿CTX-Ⅱ(r=0. 357,P=0. 002)及COMP(r=0. 206,P=0. 005)呈正相关。结论 KOA可引起尿CTX-Ⅱ及COMP水平升高,两者可作为KOA诊断及严重程度评估的参考标志物。
Objective To observe the expression of urinary collagen type Ⅱ C-telopeptide( CTX-Ⅱ) and cartilage oligomeric matrix protein( COMP) in patients with knee osteoarthritis( KOA),and explore their relevance to the severity of the disease. Methods A total of 113 patients with KOA diagnosed in the Affiliated Ben Q Hospital of Nanjing Medical University from Aug. 2017 to Mar. 2018 were included as a KOA group. Depending on the Kellgren-Lawrence( K-L)classification,they were classified: gradeⅠ27 cases,gradeⅡ34 cases,grade Ⅲ 27 cases,grade Ⅳ 25 cases. At the same time,30 healthy people during the same period were randomly chosen as a control group. The urinary CTX-Ⅱ and COMP in all subjects were detected by enzyme linked immunosorbent assay and the results were analyzed and compared. Results Levels of urinary CTX-Ⅱ and COMP in the KOA group were obviously higher than those in the control group( P < 0. 05). The levels of urinary CTX-Ⅱ and COMP in the KOA group increased gradually with the increase of K-L grade,with statistically significant difference( P < 0. 05). K-L grade in KOA patients was positively correlated with urinary CTX-Ⅱ( r = 0. 357,P =0. 002) and COMP( r = 0. 206,P = 0. 005). Conclusion KOA can cause elevated levels of urinary CTX-Ⅱ and COMP,which can both be used as reference markers for the diagnosis and severity assessment of KOA.
