<p><b>OBJECTIVE</b>To investigate reason and the management of portal vein thrombosis in patients with portal hypertension postoperatively.</p><p><b>METHODS</b>329 patients with portal hypertension in liver cirrhosis who had splenectomy was reviewed from 1992 to 2001. In whom 43 (13.1%) patients with portal vein thrombosis postoperative were analyzed.</p><p><b>RESULTS</b>In these patients, except 1 died for portal vein phlebitis, all patients were recovered. There are 138 patients who underwent splenectomy or splenectomy and devascularization, 26 (18.8%) of them had thrombosis. 191 patients underwent splenectomy and portacaval or portasplenic shut, 17 (8.9%) of them had thrombosis. The data of these two groups have significant difference (chi(2) = 8.44, P < 0.01).</p><p><b>CONCLUSIONS</b>Thrombocytosis postsplenectomy as well as the changes of portal hemodynamics is the main reason of portal vein thrombosis. Portal vein thrombosis is also in association with the operative ways. Operation standardization, dynamic examining platelet count, routine color ultrasonography examining and early anticoagulation therapy are the effective methods in preventing and managing portal thrombosis postoperation for portal hypertension.</p>

<p><b>OBJECTIVE</b>To investigate the expression of four hepatocellular cancer antigen (HCA) gene mRNA in hepatocellular carcinoma.</p><p><b>METHODS</b>The expression of HCA90, HCA519, HCA520, HCA587 mRNA was detected using RT-PCR in HCC tissues and the corresponding adjacent non-HCC tissues from 46 HCC patients, cirrhosis tissues from 10 samples and normal liver tissues from 10 samples. The relationship between positive expression rate of HCA gene and clinical and lab data was evaluated.</p><p><b>RESULTS</b>Of 46 HCC tissues, HCA90, HCA519, HCA520 and HCA587 mRNA were detectable in 65.2%, 76.1%, 45.7% and 32.6%, respectively. At least one HCA gene mRNA was positive in 82.6% of HCC tissues. Only weak expression of HCA519 could be detectable in 6.5% of the corresponding adjacent non-HCC tissues. None of 10 samples of cirrhosis and normal liver tissues expressed any HCA gene mRNA. No correlation was found between the expression of HCA and clinical date such as age, sex, tumor size, tumor differentiation, serum alpha-fetoprotein level and hepatitis B virus infection or hepatitis C virus infection (P > 0.05). However, in some patients with normal serum alpha-fetoprotein (< 25 ng/L), specific expression of HCA genes was observed.</p><p><b>CONCLUSION</b>HCA gene mRNA is expressed with a high percentage and specificity in hepatocellular carcinomas and their products are new potential promising targets for immunotherapy of HCC.</p>
