拉米夫定联合阿德福韦酯治疗乙型肝炎肝硬化失代偿期患者的临床观察

目的:探讨拉米夫定(LAM)联合阿德福韦酯(AVD)治疗乙型肝炎肝硬化失代偿期的疗效、安全性。方法:选择2006年6月～2008年6月门诊和住院乙型肝炎肝硬化失代偿期患者93例,随机分为3组。A组单用LAM(100mg·d-1);B组采用ADV(10mg·d-1);C组采用ADV(10mg·d-1)、LAM(100mg·d-1)联合治疗;3组均治疗52周。结果:治疗52周时3组患者间ALT水平、HBeAg阳性患者血清转换率比较,差异均无统计学意义(P>0.05);C组患者HBVDNA水平达到检测水平以下的百分率与B组患者比较,有显著性差异(P<0.05);3组间肝功能Child-Pugh评分比较差异无统计学意义(P>0.05)。3组患者的基因型耐药率分别为21.9%(7/32)、0、0。结论:乙型肝炎肝硬化失代偿期采用LAM联合ADV治疗更安全有效。     

丹参注射液与异甘草酸镁抗肝纤维化的临床对比研究

Objective To observe the change of liver function and liver fibrosis indexes of the chronic hepatitis B patients that were treated by Danshen injection(DI) and magnesium isnglyeyrrhizinate(MI). Methods 80 chronic hepati-tis B patients based on the conventional treatment were randomly divided into D1 group(40 patients) and MI group(40 pa-tients). The two groups were used with DI and MI injection for 30 days respaetively and then,the levels of liver function and serum hepatic fibrosis(HA, LN, Ⅳ -C) were detected and compared before and after treatment. Results Treatment by DI and MI could both improve liver function significantly, the effect of Ml group was better than DI group(P < 0.05). Moreover, in improving serum hepatic fibrosis, the effect of DI group was better than MI group (P < 0.05). Conclusions The efficacy of the improvement to hepatic fibrosis DI is better than MI, while in improvement of liver function MI is superior to DI.

姜黄素对实验性肝纤维化大鼠肝脏bax和bcl-2表达的影响

[目的]探讨姜黄素(curcumin,CUR)对大鼠肝纤维化的防治作用及对肝组织bax和bcl-2蛋白及基因表达的影响.[方法]建立CCl4致大鼠实验性肝纤维化模型.用免疫组化法比较正常组、模型组以及CUR组的bcl2、bax蛋白的表达,用RT-PCR法比较各组肝组织bcb-2、bax mRNA的表达.[结果]CUR组肝组织炎症和纤维化程度较模型组显著减轻.bax蛋白主要表达在肝细胞质,而纤维间隔及汇管区呈低表达;beb-2主要表达在纤维间隔及汇管区.bax及bcl-2在模型组及CUR组表达均高于正常组(P<0.01),CUR组均较模型组降低(P<0.01).bax及bcI-2 mRNA在模型组及CUR组表达比正常组增高(P<0.01,<0.05),CUR组均较模型组降低(P<0.05).[结论]CUR可能通过降低肝细胞表达bax、减少肝细胞凋亡而减轻肝脏损伤,通过降低bcl-2表达、诱导肝星状细胞凋亡发挥减轻肝纤维化的作用,防治大鼠肝纤维化.     

姜黄素对肝纤维化大鼠肝组织中NF-κB及ERK-1 mRNA表达的影响

目的 探讨核转录因子-κB(nuclear factor kappa B,NF-κB)及细胞外信号调节激酶(extracegular signal-reglulated kinase,ERK)mRNA在CCl4致实验性肝纤维化大鼠肝组织中的表达及姜黄素(curcumin,CUR)对它们的影响.方法 建立CCl4致大鼠实验性肝纤维化的模型,用免疫组化法比较正常组、模型组及CUR组的α平滑肌肌动蛋白(α-SMA)的表达,用RT-PCR法比较各组肝组织NF-κB及ERK-1 mRNA的表达.结果 模型组中,ERK-1及NF-κB mRNA的表达均增高,而CUR组α平滑肌肌动蛋白则较模型组低,NF-κB及ERK-1 mRNA的表达也降低.结论 CUR可能通过抑制α-SMA的表达,减弱NF-κB诱导的肝星状细胞的活化及抑制ERK-1促肝星状细胞的增殖,从而产生抗四氯化碳诱导的大鼠肝纤维化的作用.
