目的 :探讨实验性肝硬化细胞生长激素受体的表达变化。方法 :采用硫代乙酰胺腹腔注射复制大鼠肝硬化模型 ,采用放射配体法、RT -PCR、图像分析检测不同阶段肝硬化肝组织和肝硬化肝细胞中生长激素受体及其mRNA的表达水平 ,并分别与正常... 目的 :探讨实验性肝硬化细胞生长激素受体的表达变化。方法 :采用硫代乙酰胺腹腔注射复制大鼠肝硬化模型 ,采用放射配体法、RT -PCR、图像分析检测不同阶段肝硬化肝组织和肝硬化肝细胞中生长激素受体及其mRNA的表达水平 ,并分别与正常肝组织和正常肝细胞比较。结果 :大鼠肝硬化肝组织表达生长激素受体 ,其表达数量明显少于正常肝组织 ,并且随着肝硬化的进展、肝组织胶原纤维相对含量的增加而进一步减少 ;大鼠肝硬化肝细胞生长激素受体的位点数量明显少于正常肝细胞 ,大鼠肝硬化肝组织生长激素受体mRNA的表达量也明显少于正常肝组织。结论 :大鼠肝硬化肝细胞表达生长激素受体 ,其表达水平降低 ;肝硬化越严重 ,该表达减少越明显。大鼠肝硬化肝组织生长激素受体表达下调的机制可能是肝硬化肝组织生长激素受体mRNA的表达明显减少。 展开更多

AIM: To estimate if and to what extent long acting octreotide (LAR) improves survival and quality of life in patients with advanced hepatocellular carcinoma (HCC). METHODS: A total of 127 cirrhotics, stages A-B, due to chronic viral infections and with advanced HCC, were enrolled in the study. Scintigraphy with 111Indium labeled octreotide was performed in all cases. The patients with increased accumulation of radionuclear compound were randomized to receive either oral placebo only or octreotide/octreotide LAR only as follows: octreotide 0.5mg s.c. every 8 h for 6 wk, at the end of wk 4-8 octreotide LAR 20 mg i.m. and at the end of wk 12 and every 4 wk octreotide LAR 30mg i.m.. Follow-up was worked out monthly as well as the estimation of quality of life (QLQ-C30 questionnaire). Patients with negative somatostatin receptors (SSTR) detection were followed up in the same manner. RESULTS: Scintigraphy demonstrated SSTR in 61 patients. Thirty were randomized to receive only placebo and 31 only octreotide. A significantly higher survival time was observed for the octreotide group (49 ± 6 wk) as compared to the control group (28 ± 1 wk) and to the SSTR negative group (28 ± 2 wk), LR = 20.39, df = 2, P < 0.01. The octreotide group presented 68.5% lower hazard ratio [95% CI (47.4%-81.2%)]. During the f irst year, a 22%, 39% and 43% decrease in the QLQ-C30 score was observed in each group respectively.CONCLUSION: The proposed therapeutic approach has shown to improve the survival and quality of life in SSTR positive patients with advanced HCC. 展开更多
