RÉSUMÉ

Objective:To explore the expression and predictive value of serum CD36 level in cardio-vascular risk in patients with rheumatoid arthritis (RA) and to provide a new theoretical basis for clinical iden-tification and prediction of patients at moderate and high cardiovascular risk in RA patients.Methods:Eighty-four RA patients hospitalized to the Department of Rheumatology and Immunology of the second hospital of Lanzhou University in Gansu Province were selected as the study subjects, and 34 healthy people were selected as the controls. All RA patients were divided into low cardiovascular risk groups and medium and high cardiovascular risk groups according to prediction for ASCVD risk in China (China-PAR) cardiovascular risk assessment. At the same time, they were tested for serological indicators at admission. Statistical Product and Service Solutions (SPSS)) 26.0 software was used for the statistical data analysis. T-test and nonparametric test were used for comparison of the measurement data. The Chi-square test and Fisher's exact test were used for the comparison of classified data. Variables with P<0.05 in univariate analysis were included into the Logistic regression model. Results:Compared with the healthy control group, the number of patients with medium and high cardiovascular risk in RA[8 cases (23.5)% and 38 cases (45.2)%, χ2=4.80, P=0.029] was significantly higher and was negatively correlated with serum CD36 ( r=-0.27, P<0.05). Logistic regression analysis showed that age [ OR(95% CI)=1.654(1.157, 2.365), P=0.006] and diastolic blood pressure [ OR(95% CI)=1.225(1.040, 1.442) , P=0.015] were independent risk factors for medium and high cardiovascular risk in RA patients, and serum CD36 level [ OR(95% CI)=0.569(0.352, 0.922) , P=0.022] was the protective factor of medium and high cardiovascular risk in RA patients according to the results of Logistic regression analysis. The area under the receiver operating characteristic (ROC) area under the curve (AUC) was 0.691, the cut-off value was 4.27 pg/ml, and the sensitivity and specificity were 89.7% and 41.0% respectively. Conclusion:The serum CD36 level decreases with the increase of cardiovascular risk in RA patients. A higher serum CD36 level is a protective factor of cardiovascular risk in RA patients, and CD36 has a certain predictive value for cardiovascular risk in RA patients and is a potential predictor.

RÉSUMÉ

Objective:To explore the clinical application and long-term safety of hydroxychloroquine sulfate (HCQ) in the treatment of rheumatic diseases.Methods:A multi-center cross-sectional study was conducted between August 2017 and August 2018 in a random sample of eleven medical institutions of rheumatology and immunology in China. Patients who took HCQ for more than 3 months were enrolled into this study. The cumulative dose and long-term side effects of HCQ were recorded. The changes of laboratory indexes before and after treatment with HCQ were analyzed. Categorical variables were presented with counts and proportions, and evaluated by Chi-square test. Continuous parametric data were presented as Mean±standard deviation, and evaluated by Student's t test or Mann-Whitney U test. P-values less than 0.05 were considered statistically significant. Results:A total of 886 patients with rheumatic diseases were enrolled into this study, including 505 cases with systemic lupus erythematosus (57.0%), 210 cases with rheumatoid arthritis (23.7%), 80 cases with Sj?gren's syndrome (9.0%), 57 cases with undifferentiated connective tissue disease (6.4%), 12 cases of systemic vasculitis (1.4%), 10 cases of mixed connective tissue disease (1.1%), 7 cases of myositis (0.8%) and 5 cases with systemic sclerosis (0.6%). The most common long-term side effects of HCQ was skin or mucous lesions (12.4%) and vision problems (8.0%). Other adverse reactions included problems of digestive system (3.0%), nervous system (2.1%), musculoskeletal system (1.1%) and cardiovascular system (0.9%). 140 cases (15.8%) had stopped taking HCQ during the treatment. More than half of them decided to stop taking medicine by themselves. Fifty-four patients (6.1%) stopped using HCQ due to side effects while 24 of them took it again, and another 12 patients (1.4%) stopped the drug due to remission of illness. Patients were divided into three groups according to the cumulative dose of HCQ: less than 500 g, 500-1 000 g and more than 1 000 g respectively. There was significant difference in the incidence of long-term side effects among the three groups ( χ2=6.382, P=0.041). The last group (more than 1 000 g) suffered the highest incidence of long-term adverse reactions (37.1%). No severe adverse drug reactions were observed in this study. Conclusion:Hydroxychloroquine is widely used in the treatment of rheumatic diseases. The incidence of long-term side effects is 20.4%, is 6.1% lead to drug withdrawal, which are especially related to the cumulative doses. It should be adjusted properly according to the clinical application.

RÉSUMÉ

Objective To investigate the possible differences in safety and efficacy between re-use and initial use in patients with ankylosing spondylitis (AS) treated with tumor necrosis factor inhibitors (TNFi). Methods From October 2016 to October 2017, 82 patients with AS who were admitted to the Second Hospital of Lanzhou University were studied. Among them, 57 patients used TNFi for the first time and 25 patients reuse it after the interruption. After 3 months of standardized use of TNF-inhibitor, we compared the efficacy indicators [visual analogue scale/score (VAS), morning stiffness, bath ankylosing spondylitis disease activity index (BASDAI), Bath ankylosing spondylitis functional index (BASFI), Bath ankylosing spondylitis metroloty index (BASMI), ankylosing spondylitis disease activity score (ASDAS), C-reactive protein (CRP), erythrocyte sedimentation rate (ESR) 0 and safety events between the two groups. T test and covariance analysis were used. Results The efficacy indexes of the two groups after treatment were significantly improved, the difference was statistically significant (P<0.05) compared with the baseline [Before and after treatment in the first treatment group: ESR: (40±31) mm/1 h, (8±8) mm/1 h, CRP: (28±35) mg/L, (5±9) mg/L, VAS: (6.5±1.6), (2.0 ±1.7), Morning stiff time: (0.6 ±0.4) h, (0.1 ±0.2) h, BASDAI: (5.0 ±1.3) h, (1.6 ±1.2) h, BASFI: (4.1 ±2.3), (1.3±1.3), BASMI: (2.6±2.0), (0.8±1.0), ASDAS: (3.5±0.8), (1.2±0.7); Before and after treatment in the re-use group: ESR: (39 ±33) mm/1 h, (9 ±10) mm/1 h, CRP: (28 ±28) mg/L, (5 ±6) mg/L, VAS: (6.6 ±1.9), (1.6 ±1.0), Morning stiff time:(0.6±0.4) h, (0.1±0.1) h, BASDAI:(5.1±0.8), (1.4±1.4), BASFI (5.1±2.2), (1.3±1.4), BASMI:(3.4 ±1.8), (1.0 ±0.9), ASDAS: (3.6 ±0.8), (1.2 ±0.4)]. But there was no statistical significant difference between the two groups in patients after treatment (P>0.05).

RÉSUMÉ

Objective To investigate the role of astroglial glutamate-glutamine shuttle in the development of neuropathic pain (NP) in rats. Methods Forty-eight adult male SD rats weighing 200-230 g were randomly divided into 8 groups (n =6 each): Ⅰ control group (group C);Ⅱ sham operation group (group S);group ⅢNP;Ⅳ-Ⅶ 0.01, 0.03, 0.05 and 0.10 mmol/L methionine sulfoximine (MSO, an inhibitor of glutamine synthetase (GS)) group (group M1-4 );Ⅷ MSO + glutaminate group (group MG). In group C no operation was performed. In group S the sciatic nerve was only exposed but not ligated. NP was induced by ligation of the tibial nerve and commom peroneal nerve according to the technique described by Dixon. After the establishment of the model, intrathecal PBS 50 μl was injected in group NP, IT 0.01, 0.03, 0.05 and 0.10 mmol/L MSO 50 μl was injected intrathecally in group M1-4, and 0.05 mmol/L MSO 50 μl was injected intrathecally and then 0.25 mmol/L glutamine 50 μl was injected intrathecally 15 min later in group MG. Mechanical pain threshold was measured 1 week before ligation (T0 , baseline), 1 week after ligation (T1) and 15, 30, 45 and 60 min after injection of MSO (T2-5). Then rats were killed and the lumbar segment of the spinal cord was removed for determination of the expression of glial fibrillary acidic protein (GFAP) and GS and the co-expression (GFAP/GS) in the dorsal horn.Results Mechanical pain threshold was significantly lower at T1-5 in group MG and NP and at T2-4 in group M3.4 ,and the expression of GFAP, GS and GFAP/GS was significantly higher in group MG,NP and M3 than in group S and C ( P < 0.05) .Conclusion Astroglial glutamate-glutamine shuttle in the spinal cord is involved in the development of neuropathic pain in rats.
