Objective To explore the effect of the JAK/STAT signal pathway on the apoptosis-related gene in the synovial tissue of rat rheumatoid arthritis (RA).Methods Fifty rat models of collagen-induced arthritis,whose arthritis index was more than 2,were divided into the model group,the low dose of AG490 group,the medium dose of AG490 group and the high dose of AG490 group.In addition,6 rats were treated intraperitoneal injection.Then,the arthritis index and the change of apoptosis-related genes were compared.Multiple-sample average was analyzed by single-factor x2 test and LSD-t or Tamhane's T 2 test were used for two-two comparison.Results The arthritis index of the model group increased evidently,and the apoptosis inhibitor Bcl-2,Bcl-xl gene and protein expression was up-regulated,which was significantly different when compared with that of the control group(0.931±0.035 vs 0.351±0.024,0.920±0.037 vs 0.271±0.029,0.322±0.047 vs 0.230±0.031 ).The expression of apoptosis promoting factor Bax wasslightly up-regulated.The blockage of JAK/STAT pathway cotld down-regulate the expression levels of the gene and protein of survivins Bcl-2 and Bcl-xl,and up-regulate the gene and protein expressions of Bax.Conclusion In the process of RA development,apoptosis inhibitor Bcl-2,Bcl-xl gene and protein expression is up-regulated.JAK/STAT signal transduction pathway regulates the apoptosis process.

OBJECTIVETo establish the quality standard of Entadae Semen, and provide scientific basis for its quality control.

METHODTLC and HPLC were used for qualitative identification and quantitative analysis of phaseoloidin and entadamide A-O-β-D-glucopyranoside in Entadae Semen. The test of water content, ash and ethanol-soluble extractives of Entadae Semen was carried out according to the methods recorded in appendix of Chinese Pharmacopeia (2010 edition).

RESULTThe TLC was well separated with clear spots. The linear range of phaseoloidin was between 0.014 to 2.747 g x L(-1) (r = 0.999 6, n = 9) with an average recovery rate of 101.06% (RSD 0.90%, n = 6); the linear range of entadamide A-O-β-D-glucopyranoside was between 0.002 to 0.452 g x L(-1) (r = 0.999 7, n = 9) withan average recovery rate of 101.52% (RSD 1.09%, n = 6). The content of phaseoloidin in sample is between 5.12% to 9.24%, entadamide A-O-β-D-glucopyranoside is between 0.55% to 2.17%, alcohol-soluble extracts is between 30.9% to 45.2%, water is between 6.6% to 8.6%, and total ash is between 2.4% to 2.9%.

CONCLUSIONThe established standard is acceptable for quality control of Entadae Semen.

AIM: To study the expression of nuclear factor kappa B (NF-?B) in the L 1-L 4 spinal ganglions of adjuvant arthritis (AA) rats, to explore the neuroendocrinoimmunological mechanism of rheumatoid arthritis (RA). METHODS: The expression of the NF-?B protein was detected by immunohistochemistry method and the alteration of the active NF-?B protein (nuclear protein) was investigated by Western blotting analysis. RESULTS: The expression of NF-?B protein in L 1-L 4 spinal ganglions of AA rats was much higher than that in the healthy controls ( P

12-18 years old).In each age group,children were classified according to their genders.Diffusion tensor imaging(DTI)was performed in all the children's heads.Then the angles formed by splenium corporis callosi and occipital forceps were measured in fractional anisotropy maps.All the data were analyzed statistically.Results 1.The females in infant group had the larger angles formed by splenium corporis callosi and occipital forceps.With the age increasing,the average values of angles tended to decrease gradually.But in some age groups,the average values in some cases tended to increase before it decreased.2.A statistically significant sex difference was found in infant group.In young child group,pre-school age group and adolescence group,such difference was found in angles formed by occipital forceps.Only in young child group,difference in the maximum angles of splenium corporis callosi was found.3.There was a significant difference between age groups in the angles formed by sides of occipital forceps and the minimum angles of splenium corporis callosi through one-way analysis of variance.4.The angles of occipital forceps and the minimum angles of splenium corporis callosi both had a negative correlation with ages.They both had a linear regression to ages.But,there was no correlation between the maximum angles of splenium corporis callosi and ages.Conclusions Sex differences might exist in the angles formed by both sides of occipital forceps and splenium corporis callosi.The angles formed by sides of occipital forceps and parts of angles of splenium corporis callosi might decrease when the age increases.Diffusion-weighted technology can be used to study the age and sex difference in angles formed by splenium corporis callosi and occipital forceps in children.

Objective To investigate the relationship between the single nucleotide polymorphism of aminoimidazole carbexamide ribonucleotide transformylase gene and the efficacy and toxicity of methotrexate treatment in rheumatoid arthritis. Methods Total of 359 patients with RA were divided into mono-therapy with MTX group, combination therapy with other DMARDs group and other DMARDs combination with no MTX treatment group. The clinical and laboratory measurements were evaluated before therapy and 12, 24 weeks after therapy. Efficacy (evaluated by ACR20) and side effects of the drugs were also assessed. Real-time fluorescent quantitative PCR was conducted to test ATIC 347C/G mutation in RA patients and 340 healthy controls. Results There was no statistical significant difference in 347 CC, CG, GG between RA patients and healthy controls. In the MTX mono-therapy group (n=107), 72% (n=77) there was no statistical significant difference in 347CC, CG, GG between patients with good response and patients without efficacy. 32.7%(n=35) of these patients experienced adverse drug reactions. The ATIC G allele carriers (22.4%) experienced a greater frequency of side effects than the CC carriers (OR=2.672, 95%CI, 1.27～5.59, P<0.05). In MTX combined with other DMARDs group (n=128) and other DMARDs combination without MTX group (n=90), the polymorphism in the ATIC gene was not associated with good clinical response and adverse events (P>0.05). Conclusion There is no statistical significant difference between RA and healthy controls in the ATIC347 gene. Polymorphism in the ATIC gene is not associated with clinical response to MTX treatment, but the ATIC347 G allele is associated with MTX toxicity. It maybe used to predict the adverse drug reactions of patients who take MTX.

Objective To study whether p38 mitogen-activated protein kinases (p38MAPK) signal pathway were activated in the process of tumor necrosis factor-like weak inducer of apoptosis (TWEAK) which then induces rheumatoid arthritis (RA) fibroblast-like synoviocyte (FLS) to synthesize matrix metalloproteinase-1 (MMP-1) and look for the relative mechanisms of how TWEAK was involved in the destruction of articular bones and cartilage. Methods RA FLS were primarily cultured and stimulated with TWEAK. FLS were pretreated with SB203580 or not. ELISA was used to detect the concentration of MMP-1 in cell-cultured supernatant. Western blotting was used to detect the expression of p-p38MAPK and P65 in RA FLS. Results TWEAK (100 ng/ml) could induce RA FIS to synthesize MMP-1. SB203580 could partially inhibite the expression of MMP-1 producted by RA FLS which was induced by TWEAK. TWEAK could make p38MAPK phosphorylated and increase the expression of P65 protein in the cell nucleus. Conclusion TWEAK induces RA FLS to synthesize MMP-1. In this process, p38MAPK signal transduction pathway is activated and then induce the expression of NF-κB.
