Objective To investigate the serum levels of anti-BRAF antibody in patients with rheumatoid arthritis (RA) and its clinical significance.Methods Blood samples from 129 patients with RA,71 patients with other rheumatic diseases and 68 healthy controls were measured by enzyme-linked immunosorbent assays (ELISA).The serum levels of anti-BRAF antibody in patients with RA were divided into high,medium and low groups,each group had 43 cases.The clinical symptoms,immunological findings and related imaging data of all cases were recorded.We investigated the relationship between the serum levels of anti-BRAF antibody and the clinical symptoms,immunological findings and related imaging changes of the RA group.Chi-square test,Mann-Whitney U test,Spearman's correlation test were used for statistical analysis.Results ① The serum levels of anti-BRAF antibody were significantly higher in RA group [A:1.093 (0.150-3.210)] than in other rheumatic diseases group [A:0.278 (0.093-0.455)] and healthy controls [A:0.202 (0.121-0.443)] (Z=-11.223,P=0.021 ; Z=-7.839,P=0.008 7).The serum levels of anti-BRAF antibody was not significantly different between patients with other rheumatic diseases group and healthy controls (Z=-0.905,P=0.445).② The difference in positive rate of rheumatoid factor (RF) in different groups of anti-BRAF antibody levels was statistically significant (λx2=10.14,P=0.006),namely the positive rate was significantlyhigher in the low-level group (88％) than in the high-level group (58％) (x2=10.03,P=0.002).Thepositive rate of anti-cyclic citrullinated peptide antibody and anti-keratin antibody of the three groups was not significantly different (x2=0.721,P=0.697; x2=1.735,P=0.188).③ There was significant negative correlation between the levels of anti-BRAF antibody and the course of disease (r=-0.233,P=0.047),RF(r=-2.84,P=0.039),IgM (r=-0.234,P=0.038),and hemoglobin (r=-0.287,P=0.032).There was no significant correlation between the level of anti-BRAF antibody and the joint swelling index (r=-0.133,P=0.230),joint pain index (r=-0.173,P=0.100),other clinical and laboratory parameters.There was significantly negative correlation between the ESR and hemoglobin level.④ There was no significant difference of the level of anti-BRAF antibody between the normal group and patients with bone destruction in the RA group (Z=-0.642,P=0.521).⑤ There was no significant difference in the level of anti-BRAF antibody between the normal group and patients with interstitial pulmonary fibrosis group in the RA group (Z=-0.121,P=0.904).Conclusion The anti-BRAF antibody can be used for the diagnosis of RA as a new autoantibody,and it can also be used in the diagnosis of early or RF-negative RA.There is no correlation between the level of anti-BRAF antibody and bone destruction and interstitial pulmonary fibrosis.

Lysyal oxidase (LOX),a cooper dependent monoamine oxidase,can stabilize the extracellular matrix and is closely related to the tumor cell differentiation,vicious transformation and invasiveness.LOX is secreted into extracellular,and it is resolved into a small fragment by sol protease,which is lysyal oxidase propeptide (LOX-PP).According to research,LOX-PP has its own structure and physiological functions,which can inhibit the growth of tumor cells.LOX-PP also plays a significant role in the generation and progression of tumor,which is likely to be a new therapeutic target.

Objective To measure the blood levels of mercury and arsenic of mother and umbilical cord, and analyze the relationship between these levels and outcome of pregnancy and complications. To explore the influential factors in order to guide a good birth and good care in pregnancy and lying-in women.Methods A total of 400 cases who were hospitalized in Xinhua hospital from March 2009 to August 2009 were included in this study. The blood levels of arsenic of mother and umbilical cord were determined by microwave digestion method and inductively coupled plasma emission mass spectroscopy method ( ICP-MS),while mercury determination was made using flame atomic absorption spectrophotometer (AAS). In addition, pregnant women were required to fill the questionnaire including their living environments, life styles,diet habits and etc. Results The newborn cord blood levels of mercury and arsenic were positively related to those of their mothers( r =0.88,0.91 respectively, P ＜0.05). The adverse pregnancy rates and complications rates in blood elevated mercury and arsenic groups were significantly higher than in the normal groups( x2 =7.07, 9. 94 respectively, P ＜ 0.01 ). Multiple regression analysis showed that the newborn blood mercury levels were significantly correlated to sea-fish eating, fruits supplement and ventilation during pregnancy. The former was a risk factor( Wald χ2 =8.28, P ＜0.01 ) and the later two were protective factors( Wald χ2 = 9.02, 6.05 respectively, P ＜ 0.05 ). Multiple regression analysis also showed that the newborn blood arsenic levels were significantly correlated to eating canned food, using cosmetics and education degree. Eating canned food and using cosmetics were risk factors(Wald χ2 =7.35, 10.38 respectively,P ＜ 0.05 ) while high education degree was protective factor( Wald χ2 = 8.87, P ＜ 0.05 ). Conclusion The newborn cord blood levels of mercury and arsenic were related to those of their mothers, environmental factors and health care during pregnancy. Health education and care during pregnancy were effective approaches for preventing mercury and arsenic poisoning.

Objective To evaluate the value of anti-carbamylated protein (CarP) antibody in the diagnosis of rheumatoid arthritis (RA).Methods The clinical data and serum of 247 in-patients with joint pain of Department of Rheumatology,General Hospital of Ningxia Medical University admitted during September 1,2015 to June 1,2016 were collected and divided into two groups according to the final diagnosis:RA group (case group) which included 126 patients and the non-RA group which included 121 patients (control group).The concentration of anti-CarP antibody in serum was measured by enzyme linked immunosorbent assay (ELISA).The serum rheumatoid factor (RF) and anti-cyclic citrullinated peptide (CCP) antibodies were detected at the same time.Mann-Whitney U nonparametric test for statistical analysis,receiver operating characteristic curve (ROC) was drawn to determine the cut-off value of anti-CarP antibody to RA diagnosis and to analyze its diagnostic efficacy.Results The ROC curve showed that the anti-CarP antibody had a cutoff value of 63.77 U/ml,with the sensitivity of 74.60％,and specificity of 71.07％.Compared with RF and anti-CCP antibody,the area under the ROC curve (A) were:Aanti-cyclic citrullinted peptide(anti-CCP)antibody (0.88)＞ARF (0.85)＞Anti-CarP antibody (0.78).There was no significant difference between the Aanti-CCP antibodies and ARF as well as ARF and Aanti-CarP antibodies (Z=1.29,P=0.20;Z=1.30,P=0.20),but there was significant difference between Aanti-CCP antibody and A anti Carp antibody (Z=2.28,P=0.02).Conclusion Anti-CarP antibody has certain value in the diagnosis of RA,and can be used as the serological index for RA diagnosis.
