BACKGROUND: Macrophage migration inhibitory factor (MIF) is mainly concerned with macrophage mobilizing function, as the upper stream cytokine of tumor necrosis factor-α(TNF-α), interleukin-1β (IL-1β), which may have critical effect in the process of the onset of rheumatoid arthritis. OBJECTIVE: To explore the correlations between the change of serum MIF and the activity of rheumatoid arthritis (RA) disease.DESIGN, TIME AND SETTING: Non-randomized control and case study, which was carried out in the Bethune International Peace Hospital of Chinese PLA from September in 2005 to October in 2006.PARTICIPANTS: Sixty RA patients were included in this study, and other thirty healthy subjects were selected as the control group. There were significant differences in age and sex between the two groups. METHODS: Clinical data of sixty RA patients were selected by carrying out retrospective analysis, then on the basis of disease activity score (DAS) accumulated points, they were divided into active and inactive group respectively, who were contrasted with 30 health adults. MAIN OUTCOME MEASURES: ① Morning stiffness (in minutes), joint tenderness index, arthrocele index, semi-quantity rheumatoid factor (RF), C-reactive protein concentration (CRP), erythrocyte sedimentation rate (ESR), and platelet count (PLT) were recorded; ② To compare the level of serum MIF, IL-1β and TNF-α among active group, inactive group, and control group; ③ The correlation analysis was carried out among the level of serum MIF, inflammatory index and clinical observation index.RESULTS: There was significantly increased in serum MIF of patients in the active group compared to of inactive and normal groups (P < 0.05), but there were no significantly differences between inactive and control groups (P > 0.05). There were significant correlations between the serum MIF concentration and active inflammatory index of RA disease, blood sedimentationrate (ESR), C-reactive protein (CRP), platelet counting (PLT), interleukin-1β (IL-1β), tumor necrosis factor-α (TNF-α), swell joint index (SJI) and tenderness joint, but no significant difference was observed between the serum MIF, age, disease course, morning stiffness and rheumatoid factor (RF).CONCLUSION: The serum MIF concentration is significantly increased in patients with RA, and it may be a useful parameter for monitoring disease activity of RA.

Objective To evaluate the feasibility of the DNA microarray method used in detecting the drug resistance of Myco-bacterium tuberculosis by comparing the traditional proportion method and the DNA microarray method for detecting the drug re-sistance of Mycobacterium tuberculosis.Methods 54 strains of Mycobacterium tuberculosis isolated from clinical specimens in our hospital from January 2012 to March 2013 were randomly extracted and their resistance to isonicotinic acid hydrazide (INH)and rifampicin(RFP)was detected by the DNA microarray method and the proportion method.The detection results were performed the comparative analysis.Results With the proportion method as the golden standard,the coincidence rates of the DNA microarray method for detecting the Mycobacterium tuberculosis resistance to INH and RFP were 75% and 91.0% respectively.Conclusion The DNA microarray technique is suitable for the rapid screening of clinical first-line drug resistant Mycobacterium tuberculosis.

Objective To study the morphological characteristics of blood-tumor barrier(BTB)model of glioma in vitro. Methods After C 6 glioma cells/endothelia ECV 304 co-cultured mixed or in Transwell or on both sides of membrane of Transwell,the morphological characters of fenestra of endothelial cells,the junction between ECV 304 cells,the interface between C 6 cells and ECV 304 cells,and perivascular-end-feet of C 6 cells were observed under transmission electron microscope(TEM)and scanning electron microscope(SEM),and compared to BTB in 4 cases with human brain glioma. Results ECV 304 cells grown to confluence were not fenestrated,but with fomation of tight junction between ECV 304 cells after co-cultured with C 6 cells mixedly,in Transwell or on both sides of membrane of Transwell;It was not found that pseudopodia from C 6 cells as co-cultured in Transwell reaching into pore of Transwell;C 6 cells co-cultured on both sides of membrane of Transwell often sticked out to the ECV 304 cells,but with no pseudopodia from C 6 cells surrounded ECV 304 cells of penetrated the endothelia clefts.Perivascular-end-feet of C 6 cells were not integrant.These characters were similar to BTB in human brain glioma.Conclusion C 6 glioma cells/endothelia cell ECV 304 co-cultures on both sides of membrane of Transwell may simulate the morphological characters of BTB in vivo in some degree.;

Objective:To monitor the dynamic changes in coagulation function and assess their clinical significance in patients with gas-tric cancer by using thromboelas to gram (TEG). Methods:A total of 178 patients with gastric cancer from March 2014 to May 2015 in Xinxiang Central Hospital were selected as the experimental group. The patients were grouped based on different tumor stages, inva-sion depths, and lymph node metastasis. The TEG results of all patients were dynamically monitored before and after operation, and 60 healthy persons were selected as normal control group. Blood coagulation change was analyzed by comparing the TEG test results. Results:Compared with those of the control group, the TEG parameters of the experimental group showed significantly decreased R and K values, as well as significantly increased Angle, CI, and MA values, and the differences were statistically significant (P<0.05). In the experimental group, the K values were significantly decreased after operation, whereas Angle, MA, and CI were significantly in-creased (P<0.05). No significant changes were observed in R, LY30, and others. TEG values were significantly different in the compari-son of values for tumor patients with different stages, different tumor infiltration degrees, and with or without lymphatic metastasis. Conclusion:Blood hypercoagulability in the perioperative period was observed in patients with gastric cancer and was positively corre-lated with tumor stages, tumor infiltration degrees, and lymphatic metastasis. Dynamic monitoring of gastric cancer perioperative TEG can provide valuable information for clinical treatment, improve the safety of gastric cancer surgery, and reduce postoperative compli-cations associated with active clinical significance.

Objective To investigate the neuroimaging and pathological features of epithelioid glioblastoma (EGBM) to improve the diagnosis.Methods The clinical and pathological features of 4 E-GBM cases were analyzed retrospectively.Results E-GBMs occurred predominantly in young adults.MRI examination showed irregular solidcystic lesion with heterogeneous or ring enhancement in 4 cases.Histological examination revealed uniform population of epithelioid or rhabdoid cells with prominent nucleoli and mitotic activity as well as geographic necrosis..Immunohistochemical staining showed various positive signals of Vimentin and S-100 protein in 4 cases,positive signal of BRAF (VE1) in 3 cases and focal positive signal of GFAP in 1 case.However,IDH-1 was negative and 1p/19q codeletion was lack.All patients were followed-up for 2-6 months.One patient had tumor recurrence 3 months and one patient died of disease 6 months after surgical excision.Conclusion E-GBM has a poor outcome and is closely associated with pleomorphic xanthoastrocytoma.MRI and epithelioid histological features are very important for the differential diagnosis.

ObjectiveTo evaluate the clinical and radiographic efficacy and safety of the combination of recombinant human tumor necrosis factor-αt receptor Ⅱ IgG Fc fusion protein (rhTNFR:Fc) and methotrexate (MTX) in patients with rheumatoid arthritis (RA). MethodsThirty patients with highly active RA were treated with rhTNFR:Fc (25 mg subcutaneously twice weekly) and oral MTX (up to 15 mg weekly). Clinical efficacy was assessed using ACR response criteria and the disease activity score in 28 joints (DAS28).Radiographs of the hands and wrists were assessed with the modified Sharp score. Chi-square test, Fisher is exact test and paired t-test were performed. ResultsAt week 52, ACR20, ACR50 and ACR70 responses were achieved by 90％, 87％ and 67％ respectively. At week 52, mean DAS28 was 3.4±1.1 compared to 6.4±0.6 at base-line(P＜0.01), with 23％ patients achieving clinical remission and 17％ patients in low disease activity. Similarly, the HAQ was improved significantly, declining from 1.18±0.56 at base-line to 0.25t±0.34 at week 52 (P＜0.01). No radiographic progression was found in 22 cases. Adverse events were mild in general.ConclusionTreatment with rhTNFR:Fc plus MTX has shown good efficacy throughout 52 study period in reducing disease activity, improving function, and retarding radiographic progression. Combination therapy for 52 weeks can achieve disease remission and no radiographic progression, which are the two goals of therapy for RA.

In recent years, the clinical experts consensuses or guidelines of ankylosing spondylitis (AS)/spondyloarthritis (SpA) have been constantly updated, but to better understand and practice, patient self-participation management is one of the key points to improve the level of diagnosis and treatment. Through questionnaire survey of these patients, we screened out the most concerned issues, and established the AS/SpA patient practice guideline working group with multidisciplinary physicians and patients. Fifteen opinions, as the AS/SpA patient practice guidelines, are proposed in accordance with the relevant principles of the "WHO guidelines development manual" , and with the international normative process.

Objective To describe the distribution of medication costs of rheumatoid arthritis patients, and to analyze the factors that may affect the costs. Methods Data were obtained from a 12-month retrospective investigation of patients with rheumatoid arthritis (RA) across China. Department of Rheuma-tology of 18 hospitals were randomly selected. The data about their social conditions, clinical conditions, medications associated with RA such as disease-modifying antirheumatic drugs (DMARDs), non -steroidal anti -inflammtory drugs (NSAIDs), steroids, biologic agents were collected, and the costs of drugs were calculated. A non-parameter test and multivariate logistic regression analysis were performed. Results Six hundred and forty six patients were enrolled into the study, 435 completed data were chosen for analysis. The results demonstrated that the average costs per patient for medications in the past year was 8018 . The total medication costs were further subdivided into the following parts: DMARDs, (represented 20% of the total costs), biologic drugs (49%), NSAIDs (4%), herbal drugs (22%), steroids (1%). Data analysis showed that patients with higher education and higher incomes, with medical insurance,better health function status and outpatients paid more on DMARDs. Extra-articular manifestations increased the odds of the high-cost group (OR: 2.180, 95%CI: 1.335～3.558, P=0.002), while poor health function status increased the probability of paying high costs (OR: 1.373, 95%CI: 1.012～1.863, P=0.041). Conclusion High medication costs in RA do exist in RA patients. The costs of medication is associated with health function status and the presence of extra-articular manifestations.

ObjectiveTo examine the clinical features of fractures and related risk factors in patients with rheumatoid arthritis(RA) in China.MethodsSix hundred and eighty-one RA patients were randomly selected from department of rheumatology of 18 hospitals of China.Data were obtained from the questionnaire,including age,sex,disease duration,the involvement of joints,treatment regimen,features of fractures etc.The possible risk factors of fracture in patients with RA were analyzed with a multi-variate Logistic regression analysis.Results① In 681 RA patients of the survey,48 patients had 54 fractures,and the incidence of fractures was about 8％.② Fractures occurred at various sites.Foot/ankle,femur,spine and wrist were the mostfrequent sites.③ The Logistic regression analysis showed that several factors increased the risk of fracture in RA patients,including long disease duration (OR:1.245,95％CI:0.987-1.570,P=0.065),male gender(OR:0.433,95％CI:0.199-0.942,P=0.035),more deformed joints(OR:1.042,95％CI:1.006-1.079,P=0.023),family history of RA (OR:2.201,95％CI:0.984-4.923,P=0.055),and high scores of SF-36(OR:1.017,95％CI:1.002-1.033,P=0.028).④ According to the degree of correlation from strong to weak,the risk factors of fracture were disease duration,SF-36,sex,number of deformed joints and family history of rheumatoid arthritis.ConclusionThe incidence of fracture is high in patients with rheumatoid arthritis.Several factors could increase the risk of fractures in RA patients,including long disease duration,male gender,more deformed joints,and family history of RA.In order to prevent the occurrence of fractures,cautions should be taken to prevent the development of fractures and treat the disease aggressively to suppress the disease activity of RA.
