Relationship between IL-10 gene -819C/T polymorphism and the risk of inflammatory bowel disease: A meta-analysis

Background: The -819C/T polymorphism in interleukin 10 (IL-10) gene has been reported to be associated with inflammatory bowel disease (IBD) ,but the previous results are conflicting.Materials and methods: The present study aimed at investigating the association between this polymorphism and risk of IBD using a meta-analysis.PubMed,Web of Science,EMBASE,google scholar and China National Knowledge Infrastructure (CNKI) databases were systematically searched to identify relevant publications from their inception to April 2016.Pooled odds ratio (OR) with 95% confidence interval (CI) was calculated using fixed- or random-effects models.Results: A total of 7 case-control studies containing 1890 patients and 2929 controls were enrolled into this meta-analysis, and our results showed no association between IL-10 gene -819C/T polymorphism and IBD risk(TT vs. CC:OR=0.81,95%CI 0.64- 1.04;CT vs. CC:OR=0.92,95%CI 0.81-1.05; Dominant model: OR=0.90,95%CI 0.80-1.02; Recessive model: OR=0.84,95%CI 0.66-1.06). In a subgroup analysis by nationality, the -819C/T polymorphism was not associated with IBD in both Asians and Caucasians. In the subgroup analysis stratified by IBD type, significant association was found in Crohn’s disease(CD)(CT vs. CC:OR=0.68,95%CI 0.48-0.97).Conclusion: In summary, the present meta-analysis suggests that the IL-10 gene -819C/T polymorphism may be associated with CD risk.Keywords: Interleukin 10, -819C/T polymorphism, inflammatory bowel diseaseDue to errors in the previous PDF especially in the 'Cite as' authors names, the PDF fulltext has been reloaded.

Zhitong Jiangu decoction mitigates osteoarthritis in rabbits via regulation of NF-κB signaling pathway

Purpose: To investigate the effect of Zhitong Jiangu decoction (ZJD) on osteoarthritis rabbits, and the mechanism of action involved. Methods: Chondrocytes were obtained from the knees of osteoarthritic rabbits. These chondrocytes were randomly assigned to 7 groups: sham, 5, 10 and 20 % normal serum groups; 5 % ZJD, 10 % ZJD and 20 % ZJD groups. The gross and histopathological features of the rabbit cartilage were examined by microscopy. Each group was treated with a different concentration of rabbit normal serum or rabbit drug-containing serum. The protective effect of different concentrations of ZJD on the cells were determined. Cell proliferation and concentrations of IL-1 and MMP-3 were determined using cell counting kit (CCK) 8 and enzyme-linked immunosorbent assay (ELISA), respectively. The mRNA and protein expressions of inhibitor of nuclear factor-κB kinase α (IKK-α) and nuclear factor kappa B p65 (NF- κB p65) were determined by quantitative reverse transcription polymerase chain reaction (qRT- PCR) and immunoblotting, as appropriate. Results: Gross and histopathological examinations of rabbit cartilage showed that osteoarthritis was successfully established in rabbit knee joint. Cell proliferation significantly and time- and concentration-dependently increased in drug-containing serum groups, relative to sham and normal serum-containing groups. However, expressions of NF-κB p65, IL-1, MMP-3 and IKK-α were markedly and time- and concentration-dependently reduced in drug-containing serum groups, relative to sham and normal serum-containing groups (p < 0.05). Conclusion: These results indicate that ZJD mitigates osteoarthritis in rabbits via regulation of NF-κB signaling pathway. Thus, it can potentially be developed for the management of osteoarthritis

Performance of the first beam on Shenguang III technical Integration Line

Technical Integration Line (TIL), which is being constructed at CAEP, is the prototype of Shenguang III fusion laser facility. Experimental results during the first integrated tests on the first line demonstrate that the laser system architecture from master oscillator through the laser amplifiers can meet the requirement of TIL engineering design. In this paper, brief introduction of TIL and main experiment results are presented
