白细胞介素-2和干扰素-γ在大骨节病患者血清和关节滑液中的变化

目的 观察白细胞介素-2(IL-2)和干扰素-γ(IFN-γ)在大骨节病(KBD)关节损伤中的变化,探讨IL-2和IFN-r在KBD关节损伤中的作用.方法 按照<大骨节病诊断标准>(GB 16003-1995),48例KBD患者和26例健康人(对照组)均来自陕西陇县KBD病区.KBD组男、女各24例,年龄在40～65岁,平均年龄51岁,采集静脉血48份和关节滑液28份(男、女各14份).对照组男、女各13人,年龄40～65岁,平均年龄49岁,采集其静脉血26份.血清、关节滑液中IL-2和IFN-γ采用酶联免疫吸附法(ELISA)测定.结果 对照组和KBD患者血清中IL-2中位数分别为46.8 ng/L和55.7 ng/L,IFN-γ分别为52.3 ng/L和48.8 ng/L,二者比较差异无统计学意义(t值分别为0.62、0.70,P均＞0.05).KBD患者关节滑液中IL-2中位数为48.3 ng/L,IFN-γ为44.1g/L,关节滑液与血清比较差异无统计学意义(t值分别为0.69、1.72,P均＞0.05).结论 KBD关节损伤患者血清和关节液中IL-2和IFN-γ均无显著性升高,表明在KBD的关节损伤过程中,IL-2和IFN-γ均未参与.

Changes of interleukin-2 and interferon-γ in serum and synovial fluid of patients with joint injure with Kashin-Beck disease

Objective To investigate the changes of interleukin(IL)-2 and interferon(IFN)-γin serum and synovial fluid of patients with joint injure with Kashin-Beck disease(KBD), and study the roles of IL-2 and IFN-γ in KBD joint injure. Methods In accordance with the "Diagnostic Criteria of Kashin-Beck disease"(GB16003-1995),48 cases of KBD patients and 26 healthy people(control group) from KBD endemic area in Long county Shaanxi province were enrolled in the study. KBD patient were 24 males and 24 females, respectively, aged 40 to 65 years (mean age 51 years). Forty-eight serum specimens and 28 synovial fluid specimens of patients(14 males and 14 females,respectively) were collected. Healthy control group were 13 males and 13 females, respectively. Twenty-six serum specimens of healthy controls were collected. Serum and synovial fluid IL-2 and IFN-γ levels were determined by enzyme-linked immunosorbent assay(ELISA). Results In healthy controls and KBD patients, the midian of serum IL-2 were 46.8 ng/L and 55.7 ng/L, respectively, and IFN-γ were 52.3 ng/L and 48.8 ng/L, respectively. The difference was not statistically significant between healthy controls and KBD patients(t = 0.62, 0.70, all P ＞ 0.05).In synovial fluid of KBD patient, the midian of IL-2 and IFN-γwere 48.3 ng/L and 44.1 ng/L, respectively. The difference was not statistically significant between serum and synovial fluid in KBD patients(t = 0.69, 1.72, all P ＞0.05). Conclusion Serum and synovial fluid IL-2 and IFN-γare not significantly increased in KBD patients with articular damage, indicating that IL-2 and IFN-γare not involved in KBD joint injury.
