Résumé
<p><b>OBJECTIVE</b>To analyze experimental results of Graft-versus-host disease (GVHD) after liver transplantation.</p><p><b>METHODS</b>13 cases of GVHD out of the 1013 liver transplantation between 2002-2008 were analysed. Routine blood test, liver function and microorganisms test were done in all of the 13 cases, bone marrow test was done in 5 cases, liver pathological test was done in 5 cases, cytokines were analyzed in 4 cases, chimerism test was done in 6 cases.</p><p><b>RESULTS</b>Leukocytes were reduced to various degree in all 13 cases, and were extremely low in 8 cases. Hematopoiesis was repressed in 4 cases. Normal liver function was found in 9 cases. Bacterium were found in blood, bile, wound secrete juice, excrement, phlegm of 10 cases. The pathological characteristics was in accordance with GVHD in 5 cases. The levels of IL-1 alpha, IL-1 beta, IL-2, IL-4 were low or undetectable. IL-10 was decreased in 4 cases but increased in 1 case. MCP-1, VEGF, IL-6, EGF, IL-8 were increasing or remained at high level during GVHD. TNF alpha was slightly increased. IFN gamma was only slightly changed before GVHD.</p><p><b>CONCLUSION</b>Chimerism is a reliable but not unique evidence of GVHD.</p>

Objective To develop an effective real time PCR method for genotyping mitochondrial aldehyde dehydrogenase-2(ALDH2)Glu504Lys polymorphism based on the hydrolysis probes.Methods The Mg~(2+)and probe concentration were optimized,the precision and sensitivity were also checked.The genotypings by this method were confirmed by the direct sequencing of amplified PCR products.Results The optimized Mg~(2+)and probe concentration were 2.5 mmol/L and 1.0 ?mol/L,respectively.The inter- group(n=20)and intra-group(n=20)CVs of Ct were 1.38% and 1.48 %,respectively.The method could detect human DNA in the range of 5.0?10~2-5.0 ?10~6 pg per 25 ?l reaction.The results from 150 individuals by this genotyping method are in full concordance with that by direct PCR products sequencing.Conclusion The combined merits of reliability,flexibility and simplicity should make this method suitable for routine clinical testing and cost-efficient large-scale genotyping.
