Purpose: Autoimmune hepatitis (AIH) is a chronic disease that may lead to cirrhosis. The immunopathogenesis of AIH is not fully understood and it mainly involves T-cell mediated mechanism. Macrophage migration inhibitory factor (MIF) is a pro-inflammatory cytokine that promotes T cell response and its polymorphism may serve as a severity marker of AIH. No previous study has considered investigating MIF polymorphism in children with AIH. Methods: Forty-two children with definite diagnosis of AIH were enrolled along with 100 age and sex matched controls. All participants were tested for polymorphism at -173GC (rs755622) of MIF gene. All patients received the standard protocol of steroid plus azathioprine to achieve remission. Liver biopsy was performed at time of diagnosis for all patients and only 18 of them underwent a second biopsy after treatment. Results: No statistically significant differences in the frequency of the genotypes GG and GC or in allele distribution were found in both patient and control groups (p=0.590, 0.640 respectively). Initial alanine aminotransferase (ALT) levels at the time of presentation was significantly higher in the GC group than GG group (p=0.020). GC genotype significantly correlated with disease relapse (r=0.41, p=0.007). Regression of necroinflammation and the fibrosis score in the second liver biopsy was statistically significant in the GG group (p<0.0001, p=0.010 respectively). Conclusion: MIF -173GC polymorphism is associated with clinically significant markers of pediatric AIH, including increased initial serum ALT levels, may help predict necroinflammatory/fibrosis regression effectively, following immunosuppressive treatment.

Marine structures including offshore wind turbines (OWTs) always work under cyclic loads, which arouses much attention on the fatigue design. The tripod substructure is one of the typical foundation forms for fixed OWTs. The three-planar tubular Y-joint (3Y joint) is one of the important components in fatigue design as it is most likely to have cracks. With the existence of the multiplanar interaction effect, calculating the hot spot stress (HSS) of 3Y joints is complicated. To assist with fatigue design, the distributions of stress concentration factor (SCF) and multiplanar interaction factor (MIF) along weld toe curves induced by the out-of-plane bending moment are explored in this study. An FE analysis method was first developed and verified against experimental results. This method was applied to build a numerical database including 1920 FE models covering common ranges of geometric parameters. A parametric study has been carried out to reveal the distribution patterns of SCF and MIF. After multidimensional nonlinear fittings, SCF and MIF distribution formulas have been proposed. Accuracy and reliability checking prove that the proposed formulas are suitable for calculating the HSS of 3Y joints.

Background: Macrophage migration inhibitory factor (MIF) -173G/C (rs755622) gene polymorphism has been associated with cancer risk. Previous studies have revealed that MIF -173G/C gene polymorphism may increase cancer in the Chinese population, while results of individual published studies remain inconsistent and inconclusive.We performed this meta-analysis to derive a more precise estimation of the relationship. Materials and Methods: We conducted a search on PubMed, Embase, MEDLINE, Cochrane Library, Chinese National Knowledge Infrastructure (CNKI), Wanfang, Weipu on Dec 31, 2014.Odds ratio (OR) and 95% confidence interval (95% CI) were used to assess the association. A total of eight studies including 2,186 cases and 2,285 controls were involved in this meta-analysis. Results: The pooled results indicated the significant association between MIF -173G/C polymorphism and the risk of cancer for Chinese population (CC + CG vs GG: OR=1.14, 95%CI=1.02-127, pheterogeneity<0.01; P=0.023; CC vs CG+GG: OR=1.12, 95%CI=1.02-1.23, pheterogeneity<001; P=0.017;CC vs GG: OR=1.18, 95%CI=1.04-1.33, pheterogeneity<001; P=0.008; CG vs GG:OR=1.03, 95%CI=0.91-1.15, pheterogeneity<001; P=0.656; C vs G:OR=1.24, 95%CI=1.14-1.25, pheterogeneity<001; P<001). Subgroup analysis showed that in patients with "solid tumors", heterogeneity was very large (OR=0.94,95%CI=0.83-1.06,pheterogeneity=0.044; p=0.297). Within "non-solid tumors", the association became even stronger (OR=6.62, 95 % CI=4.32-10.14, pheterogeneity<0.001; p<0.001). Conclusions: This study suggested that MIF -173G/C gene polymorphism may increase increase cancer in the Chinese population.Furthermore, more larger sample and representative population-based casees and well-matched controls are needed to validate our results.

점토광물들은 지질환경에 따라 다양한 화학성분을 갖게되는데, 화학성분의 변화는 X-선 회절도형 회절선 intensity에도 영향을 미치기 때문에 점토광물들의 정확한 정량분석을 위하여서는 유사한 화학식을 표준시료를 필요로 하게 된다. 대부분의 경우 특정성분의 표준시료를 확보하기 어렵지만, X-선 회절도형 계산방법을 응용하면 표준시료를 사용하지 않고 점토광물들의 정량분석을 실시할 수 있다. 대부분 심해저 퇴적물은 smectite, illite, chlorite, kaolinite듣 점토광물들을 함유하고 있는데, 특정한 화학성분을 갖는 이러한 네가지 점토광물들의 X-선 회절도형을 NEWMOD 프로그램을 이용하여 계산하였다. smectite와 illite의 001 회절선, chlorite의 004회절선, kaolinite의 002회적선의 이론적 peak intensity들을 계산된 X-선 회절도형으로부터 구하여 각 광물들의 MIF(Mineral Intensity Factor)값을 결정하였다. 실험에서 얻어진 시료의 peak intensity는 MIF값을 이용하여 교정하면 peak intensity값과 각 광물들의 wt%가 비례하도록 된다. 각 광물들의 wt% 총합계는 100wt%가 되도록 설정한 후 각 광물들의 구성비율을 이용하여 정량화 하였다. 이러한 정량분석방법은 분석하려는 광물의 화학식과 거의 비슷한 표준시료를 준비하지 않아도 되기때문에, X-선 회절도형의 계산방법을 이용한 정량분석은 표준시료를 구할 수 없거나 구하기 힘든 경우 유용하게 사용될 수 있다. 회절도형계산을 이용한 정량분석 방법은 서로 비슷한 지질환경에서 산출된 점토광물들을 대량으로 빠른 시간내에 분석하는데 이용할 수 있다.

Rheumatoid arthritis(RA) is a general, chronic, inflammatory and auto-immune disease and it can lead to joint edema, pain, stiffness which are caused by an inflammation in synovium covering our joints. Ulmus davidiana Planchon is a traditional herb used for the treatment on various inflammations, gastrointestinal trouble, ENT(ear, nose, and throat) disease, edema, cancer etc. and it works effectively on arthritis as well. In these study to search for the treatment efficacy of Ulmus davidiana Planchon in RA, I measure manifestation of cytokine gene in synoviocyte treated with Ulmus davidiana Planchon herbal acupuncture and in EL-4 cell, manifestation of cytokine gene cell related to T-cell. And after Ulmus davidiana Planchon herbal acupuncture treatment in Collagen induced arthritis(CIA) which has been known by a general model of RA, DBA mice, I observed foot thickness, general shape of synovium, early cytokine induce CIA and, generation and mutation of cytokine related to the control of T-cell specialization. It comes to conclusion as belows. 1. In synovium treated with Ulmus davidiana Planchon herbal acupuncture, there was the decrease in MIF mRNA does-dependently. Incase of CIA mice treated with Ulmus davidiana Planchon herbal acupuncture, there were the decrease in the damage in synovium and generation of the MIF which is related to induction of the early RA cytokine and IL-6 proinflammatory cytokine. 2. In case of EL-4 treated with Ulmus davidiana Planchon herbal acupuncture, there were decrease in the manifestation of the IL-2 mRNA, but the increase in the manifestation of the IL-4 does-dependently. 3. In the synovium of CIA mice treated with Ulmus davidiana Planchon herbal acupuncture, there were the decrease in generation of IL-2, IL-12 and CD-28, but the increase in generation of IL-4. These result suggest that Ulmus davidiana Planchon can block the process of the early RA by Inhibiting MIF activation, and mitigate Rheumatoid Arthritis by controlling Tcell specialization.

Oriental medicine explains aging as the weakening of Kidney-ai, and Kidney-strengthening herbal medicines such as Yukmijihwang-tang have been studied for anti-aging effects. In Western Medicine, the hypothesis that reactive oxidant species(ROS) contribute to the aging process is generally accepted. It has been reported that Moutan Cortex Radicis extract (MCR) was the most effective constituent of Yukmijihwang-tang in decreasing ROS production in oxidative-stressed cells. The purpose of this study is to confirm the anti-oxidant effect of MCR on PC12 cells, the expression of Heme oxygenase (HO), Macrophage migradon inhibitory factor (MIF), Catechol-O-methyltransferase (COMT) using real time RT PCR. PC12 cells were treated without or with hydrogen peroxide in the presence or absence of MCR using MTS assay. Hydrogen peroxide decreased the viability of PC12 cells by 53% and MCR did not influence that of stressed PC 12 cells irrespective of dose or incubation period. However, MCR showed an inhibitory effect on production of ROS in stressed cells, both dose and incubation time dependently. In particular, 1 ㎎/㎖ of MCR for 24 h culture almost returned to normal level. In the quantiation of anti-aging related gene expression, MCR at 1 ㎎/㎖ increased the expression of HO by 370%, MIF by 180% and COMT by 280% through real time RT PCR. In conclusion, MCR treatment protected PC12 cells from hydrogen peroxide and decreased ROS production and enhanced anti-oxidative gene expression such as HO, COMT and MIF, which suggests that MCR is involved in controlling anti-aging of nerve cells through elimination of cytotoxic stimuli.
