Clinicopathological analysis of biliary tract complications on post-liver transplantation patients / 中华肝脏病杂志

<p><b>OBJECTIVE</b>To analyze the pathohistological changes of the livers and the clinical features of patients with biliary tract complications after their orthotopic liver transplantations.</p><p><b>METHODS</b>From Sept 1998 to June 2005 clinical and pathological data of 173 post-liver transplantation patients with biliary tract complications were analyzed.</p><p><b>RESULTS</b>Biliary tract complications occurred within 3-2920 days after the transplantation operations. These complications occurred within 1-30 days, 31-90 days, 91-180 days, 180 days at rates of 49.71%, 17.92%, 4.62%, 27.74% respectively. The complications were of inflammatory nature in 171 cases, (72.25%), and of obstructive nature in 164 cases (27.74%). The main pathological changes were epithelium degeneration of interlobular bile ducts, inflammatory cell infiltration in portal areas, proliferation of interlobular bile ducts, fibrosis in portal areas, cholestasis in small bile ducts and hepatocytes.</p><p><b>CONCLUSION</b>Many of the biliary tract complications of post-liver transplantation in our cases were of inflammatory nature and they often occurred within 30 days after the surgery. Obstructive nature complications often occurred in 90 days after the surgery and the prognosis of these cases was much poorer. The pathological changes of live tissues shown in liver biopsies are important for prognostic evaluation, differential diagnosis and categorization of biliary tract complications.</p>

Expression and significance of Survivin mRNA in lung cancer tissue microarray detected by FISH / 中国医学科学杂志(英文版)

<p><b>OBJECTIVE</b>To investigate the expression of Survivin mRNA in lung cancer tissue microarray (TMA) by fluorescence in situ hybridization (FISH) method, and determine the role and significance of it in lung cancer genesis and progress.</p><p><b>METHODS</b>The expression of Survivin mRNA was detected by FISH method and TMA technology. Fifty-four cases of lung cancer and 10 cases of normal lung tissue were examined.</p><p><b>RESULTS</b>Survivin mRNA was expressed in 66.7% (36/54) of lung cancer; the positive ratio of lung cancer was significantly higher than that of normal lung tissue (0/10; chi2 = 15.238, P < 0.05). The positive ratio of Survivin mRNA was significantly higher in poor differentiated cancer (20/24, 83.3%) than moderate and well differentiated cancer (16/30, 53.3%; chi2 = 5.40, P < 0.05). The positive ratio of Survivin mRNA was significantly higher in group with lymph node metastasis (27/32, 84.4%) than without lymph node metastasis (9/22, 40.9%; chi2 = 11.084, P < 0.05). The positive ratio of Survivin mRNA was significantly higher in stage III-IV(12/13, 92.3%) than stage I - II (24/41, 58.5%; chi2 = 5.066, P < 0.05).</p><p><b>CONCLUSION</b>Survivin mRNA highly expresses in lung cancer, which is related to the progress and malignant behavior. Survivin may play a promoting role in lung cancer genesis and progress and provide a basis for estimating prognosis and treatment.</p>
