| 1 | Prevalence of autoantibodies and the risk of autoimmune thyroid disease in children with chronic hepatitis C virus infection treated with interferon-α显示文摘AIM: To evaluate the prevalence of autoantibodies in chronic hepatitis C virus (HCV)-infected children focusing on thyroid autoimmunity. METHODS: We investigated the prevalence of auto- antibodies in 123 chronic HCV-infected children before, during and after monotherapy with interferon-alpha (IFN-α) or combined treatment with interferon-α or peginterferon-α and ribavirin. Besides antibodies against smooth muscle (SMA), nuclei (ANA), and liver/kidney microsomes (LKM), the incidence of anti- thyroid peroxidase antibodies as well as thyroid function parameters (TSH, FT3 and FT4) were determined. RESULTS: We found that 8% of children had autoantibodies before treatment. During treatment, 18% of children were found positive for at least one autoantibody; 15.5% of children developed pathologic thyroid values during IFN-α treatment compared to only one child before therapy. Six children had to be substituted while developing laboratory signs of hypothyroidism. CONCLUSION: Our data indicate a strong correlation between interferon-α treatment and autoimmune phenomena, notably the emergence of thyroid antibodies. The fact that some children required hormone replacement underlines the need of close monitoring in particularly those who respond to therapy and have to be treated for more than 6 mo. | Stephan Gehring Ulrike Kullmer Sabine Koeppelmann Patrick Gerner Philip Wintermeyer Stefan Wirth | 2006 | World Journal of Gastroenterology2006，12，36： | 2 |

| 5 | Laser capture microdissection and genetic analysis of carbon-labeled Kupffer cells显示文摘AIM: To develop a method of labeling and microdissecting mouse Kupffer cells within an extraordinarily short period of time using laser capture microdissection (LCM). METHODS: Tissues are complex structures comprised of a heterogeneous population ofinterconnected cells. LCM offers a method ofisolating a single cell type from specific regions of a tissue section. LCM is an essential approach used in conjunction with molecular analysis to study the functional interaction of cells in their native tissue environment. The process of labeling and acquiring cells by LCM prior to mRNA isolation can be elaborate, thereby subjecting the RNA to considerable degradation. Kupffer cell labeling is achieved byinjecting India ink intravenously, thus circumventing the need for in vitro staining. The significance of this novel approach was validated using a cholestatic liver injury model. RESULTS: mRNA extracted from the microdissected cell population displayed marked increases in colonystimulating factor-1 receptor and Kupffer cell receptor message expression, which demonstrated Kupffer cell enrichment. Gene expression by Kupffer cells derived from bile-duct-ligated, versus sham-operated, mice was compared. Microarray analysis revealed a significant (2.5-fold, q value < 10) change in 493 genes. Based on this fold-change and a standardized PubMed search, 10 genes were identified that were relevant to the ability of Kupffer cells to suppress liver injury. CONCLUSION: The methodology outlined herein provides an approach to isolating high quality RNA from Kupffer cells, without altering the tissue integrity. | Stephan Gehring Edmond Sabo Maryann E San Martin Elizabeth M Dickson Chao-Wen Cheng Stephen H Gregory | 2009 | World Journal of Gastroenterology2009，15，14： | 0 |
