| 【】 目 的 研究胆道闭锁(BA)患儿血清及肝脏中白介素-13(IL-13)的表达及意义。方 法 选取13例BA与10例胆管扩张症(CBD)患儿血清和肝脏标本进行对比研究。应用酶联免疫吸附试验检测血清中IL-13的表达水平。荧光定量RT-PCR技术和免疫印迹技术分别检测肝脏组织中IL-13 mRNA及蛋白表达水平。结 果 BA组血清中IL-13表达明显低于CBD组(154.5±18.23 pg/ml vs. 268.2±19.30 pg/ml,p<0.01)。BA组肝组织中IL-13 mRNA表达明显低于CBD组(0.0150±0.0021 vs. 0.0320±0.0050,p=0.0220)。BA组肝组织中IL-13 蛋白表达亦明显低于CBD组(0.3446±0.0150 vs. 0.5765±0.0215,p=0.0122)。 |

| Abstract: |
| Objective To study the expression pattern of interleukin-13 (IL-13) in the sera and liver tissue of biliary atresia. Methods 13 infants with biliatry atresia (BA) were studied. 10 children with congenital biliary dilatation (CBD) were studied as a control. Both the BA and CBD were confirmed at operation and histological examination on the liver tissue of biopsy. The sera level of IL-13 was measured by enzyme-linked immunosorbent assay. The expression of IL-13 mRNA in liver tissue was detected with Real-time quantitative reverse transcriptase-polymerase chain reaction. The expression of IL-13 protein in liver tissue was examined by western blotting. Results The IL-13 level in sera of BA was significantly lower than that of CBD group (154.5±18.23 pg/ml vs. 268.2±19.30 pg/ml,p<0.01). Compared with CBD group, the expression of IL-13 mRNA in liver tissue was significantly lower in BA (0.0150±0.0021 vs. 0.0320±0.0050, p=0.0220), and the expression of IL-13 protein was decreased (0.3446±0.0150 vs. 0.5765±0.0215, p=0.0122). Conclusions The expression of IL-13 in the sera and liver tissue of BA is significantly elevated. It may play a key role in the pathogenesis of BA and is worthy of further investigation． |
