前S1蛋白检测在慢性乙型肝炎患者病理诊断中的价值 总被引:13,自引:0,他引:13
乙型肝炎病毒(HBV)的外衣壳蛋白包括S蛋白、前S1蛋白(Pre-S1)和前S2蛋白,近年来一些基于血清学的研究资料显示,Pre-S1蛋白含有肝细胞膜受体,与病毒侵入肝细胞以及HBV复制关系密切.而对于肝组织中Pre-S1蛋白的表达与HBV DNA的复制状态、血清学标记及组织损伤程度等关系的研究较少,我们采用免疫组化、免疫组化双标记结合肝脏组织学病变对Pre-S1蛋白在慢性乙型病毒性肝炎病理诊断中的价值进行了初步探讨. 相似文献

Objective To establish the enzyme-linked immunosorbent assay (ELISA) for the detection of serum alcohol dehydrogenase (ADH) antibody and evaluate its role in its diagnosis of autoimmune hepatitis( AIH ). Methods The reactivity between yeast ADH and human anti-ADH serum antibody was tested by Western blot analysis. ELISA was established using yeast ADH. The method was applied in serums of 67 AIH patients,94 primary biliary cirrhosis(PBC) patients, 199 chronic hepatitis B (CHB) patients, 132 chronic hepatitis(CHC) patients, 24 alcohol hepatitis disease(ALD) patients, 99 connective tissue disease(CTD) patients and 31 healthy individuals. The positive rate of ADH antibody in the patients and healthy individuals was measured. The χ2 test was used to compare the positive rates. Results The ELISA method for detecting human anti-ADH serum antibody was established successfully and the optimum reaction conditions were defined. Western blot showed that yeast ADH has cross reactivity with human anti-ADH antibody. The positive rate of anti-ADH antibody in the AIH group [59. 7% ,40/67 ] was higher than that in the normal control group(0,χ2 = 31. 271 ,P <0. 05), PBC group (6. 4% ,χ2 =54. 492,P <0. 05), CHB group( 14. 1% ,χ2 =54. 848,P <0. 05) ,CHC group(21.2% ,χ2 = 29.269,P<0.05), ALl) group ( 25. 0% ,χ2 =8.512,P <0.05)and CTD group ( 43. 4% ,χ2 =4.229, P <0. 05). Conclusions Compared with the PBC, CHB, CHC, ALD and CTD group, the anti-ADH antibody positive rate in the serums of AIH was significantly increased. The antibody may be helpful to the diagnosis of autoimmune hepatitis. 相似文献

乙肝病毒载量对轻度慢性乙型肝炎患者肝组织中TGF-β1表达的影响 总被引:1,自引:0,他引:1
目的 :观察不同乙肝病毒载量的轻度慢性乙型病毒性肝炎(CHB)患者肝组织中细胞转化生长因子 β1(TGF -β1)表达的区别。方法 :检测87例轻度CHB患者血清HBVDNA并同期行肝穿刺 ,采用免疫组化技术检测肝组织中TGF -β1的蛋白表达。结果 :血清HBVDNA>1×10 3 拷贝/mL组 (61例 )与血清HBVDNA≤1×103拷贝组/mL(26例 )肝组织TGF -β1表达差别无统计学意义 (P>0.05)。结论 :乙肝病毒载量对轻度慢性乙型肝炎患者肝组织TGF -β1表达无显著影响。 相似文献
