目的：探讨大鼠类风湿性关节炎（RA）动物模型的制备、病理组织学观察及血清细胞因子IL-1、TNF-α检测。方法：以实验大鼠为对象,Ⅱ型胶原（CII）和完全弗氏佐剂（Complete Freund＇s Adjuvant,CFA）混合注射,不同时间点实验组大鼠（O、7、14、28、42d）所获得血样用于做IL-1、TNF-α检测,膝关节标本进行组织病理学研究。结果：模型组血清IL-1、TNF-α在急性期增高明显,与对照组差异有统计学意义（P〈0.05）。模型组关节组织标本观察到滑膜组织增生,其局部骨吸收破坏明显,软骨表层胶原纤维溶解、软骨细胞变性坏死,软骨表面凹凸不平。结论：采用异种CII与CFA制备的RA模型,可以用于RA组织病理学、发病机理及治疗方面的研究。     

Comparison of hyaluronic acid in patients with rheumatoid arthritis,systemic sclerosis and systemic lupus erythematosus

IntroductionThe aim of the present study was to determine and compare the concentration of hyaluronic acid (HA) in rheumatoid arthritis (RA), systemic sclerosis (SSc) and systemic lupus erythematosus (SLE), and its correlation with parameters of disease activity and duration. The hypothesis was that HA should be increased in rheumatic diseases. We also expected that HA could be a marker of disease activity and inflammation in some of these diseases.Materials and methodsThe study group comprised 149 patients with RA, SSc and SLE hospitalized in the Department of Rheumatology and Internal Diseases, Medical University of Bialystok (Bialystok, Poland) and 30 healthy controls. The concentrations of HA, C-reactive protein (CRP) and rheumatoid factor (RF) were measured using Architect ci8200; haemoglobin, platelets on Sysmex XS-800i; and erythrocyte sedimentation rate (ESR) on Sediplus S 2000 analysers. Statistical analysis was performed using Statistica 13.3 PL.ResultsHyaluronic acid was increased in RA, SLE and SSc when compared to controls (P < 0.001, P = 0.011, and P = 0.015, respectively). There were no differences in HA between rheumatic diseases (P = 0.840). Hyaluronic acid positively correlated with SLE activity (P = 0.025). In RA, HA positively correlated with ESR (P = 0.028) and CRP (P = 0.009). However, HA was not found to correlate with the duration of rheumatic diseases.ConclusionsHyaluronic acid concentration undergoes changes in rheumatic diseases with no difference between RA, SLE and SSc. In RA, HA concentration can be a marker of inflammation, while in SLE patients an indicator of disease activity.     

得宝松、甲氨蝶呤关节腔注射治疗类风湿关节炎及对MMP-3的影响

目的:观测类风湿关节炎(RA)患者关节液和血清基质金属蛋白酶-3(MMP-3)水平及得宝松、甲氨蝶呤联合关节腔注射治疗RA滑膜炎对MMP-3的影响,并探讨其作用机制.方法:选取类风湿关节炎滑膜炎患者48例,随机分为穿刺抽液并关节腔内注射得宝松、穿刺抽液并关节腔内注射得宝松和甲氨蝶呤2组,随访半年以上,应用酶联免疫吸附试验(ELISA)测定治疗前所有患者、治疗后复发患者再次穿刺治疗时血清和关节液MMP-3的水平以及6个月时随访到的患者的血清MMP-3水平.结果:治疗前、复发后患者关节液中MMP-3水平均明显高于血清水平且呈正相关,两组均能有效降低关节液和血清中MMP-3的水平,但联合用药组较单纯应用得宝松组更显著.结论:得宝松和甲氨蝶呤联合关节腔注射能有效的降低关节液和血清MMP-3水平,控制病情,改善预后.

Uric acid a better scavenger of free radicals than vitamin C in rheumatoid arthritis

Uric acid an endogenous aqueous antioxidant in normal humans is present in much higher concentrations than vitamin C and has been known to cover 2/3^rd of the free radical scavenging capacity in plasma. In the present study average uric acid levels of patients of rheumatoid arthritis were found to be close to the normal individuals. A unique feature was observed after classifying the patients on the basis of the duration of suffering, the patients having longer duration of disease had least uric acid levels as compared to those suffering from relatively lesser period, similar trend was observed in the ascorbic acid estimations. The decline in uric acid values with progression of the disease was much more than what was observed in case of ascorbic acid suggesting the significant role of uric acid in scavenging of free radicals. Too much lowering of Uric Acid should be checked and vitamin C should be supplemented in diet for maintaining the balance between pro oxidant and antioxidant forces to check pro oxidant insult in rheumatoid arthritis.

Lipid peroxidation and antioxidant status in patients with rheumatoid arthritis

The changes in the erythrocyte lipid peroxidation products (MDA), levels of glutathione (GSH), ascorbic acid and plasma vitamin E (non enzymatic antioxidant parameters) and activities of antioxidant enzymes superoxide dismutase (SOD), glutathione peroxidase (GP_X), catalase in erythrocytes and plasma glutathione - S - transferase (GST) activity were estimated in patients with rheumatoid arthritis. This work was undertaken to assess oxidative stress and anti oxidant status in patients with rheumatoid arthritis. It was observed that there was a significant increase in erythrocyte MDA levels, activities of SOD, GP_X, plasma GST and a significant decrease in erythrocyte GSH, ascorbic acid, plasma vitamin E levels and catalse activity in patients with rheumatoid arthritis when compared to controls. The results of our study suggests higher oxygen free radical production, evidenced by increased MDA and decreased GSH, ascorbic acid, vitamin E and Catalase activity, support to the oxidative stress in rheumatoid arthritis. The increased activities of antioxidant enzymes may be a compensatory regulation in response to increased oxidative stress.
