Objective To investigate the expression level of serum Golgi protein-73 (GP73) in patients with primary hepatocellular carcinoma (HCC), or accompanied with Budd-Chiari syndrome (BCS), and to discuss its clinical value in making early diagnosis. Methods The peripheral serum samples were collected in 490 individuals, including patients with HCC (n = 65), cholangiocarcinoma (CC, n = 35), Budd-Chiari syndrome accompanied with HCC (n = 40), type B virus hepatitis (n = 60), cirrhosis after B hepatitis (n = 60), Budd-Chiari syndrome complicated by cirrhosis (n = 60), other malignant lesions (n =50), benign hepatic lesions (n = 60) and healthy volunteers (n = 60). The expression levels of serum GP73 and AFP were determined by using Elisa and electrochemiluminescence methods separately. Results The expression level of serum GP73 in the patients with HCC , CC or BCS plus HCC were significantly higher than that in the other individuals (P < 0.05). The area under the receiver operating characteristic curve (ROC), the sensitivity, the specificity and the diagnostic accuracy of GP73 and AFP for HCC were 0.868, 90.8%, 75.5%, 77.6% and 0.739, 60%, 83.2%, 80.2% respectively. The cut-off values of GP73 and AFP were 43.40 ng/ml and 20ng/ml respectively. The area under ROC and the sensitivity of GP73 for the diagnosis of HCC were strikingly higher than those of AFP (P < 0.05), while no significant differences in the specificity and diagnostic accuracy existed between GP73 and AFP (P > 0.05). The area under ROC, sensitivity, specificity and the accuracy of GP73 for the diagnosis of CC were 0.774 , 88.6%, 72.7% and 73.9%respectively, and the optimal cut-off value was 45.40 ng/ml. Conclusion In diagnosing HCC, the expression level of serum GP73 is superior to AFP. It is hopeful that serum GP73 may be proved to be an early serum tumor marker for HCC.

Objective　To study the role of bcl-2 and bax in the pathogenesis of hepatitis D. Methods　Expression of HDAg， bcl-2 and bax in liver specimens of 79 patients with hepatitis D were studied by immunohistochemistry technique. Meanwhile， the relationship between expression of HDAg and that of bcl-2／bax in liver specimens of patients were studied by double labelling technique and serial sections.Results　bcl-2 was mainly expressed in the cytoplasm of hepatocytes， bax mainly in the cytoplasm of hepatocytes and partly in the nucleus of hepatocytes， and HDAg mainly in the nucleus of hepatocytes. Most of HDAg and bax positive cells were distributed among infiltrating lymphocytes at the periportal region especially at the advancing edges of areas of “piecemeal necrosis”. Most of hepatocytes of bax positive was found to locate near to positive cells of HDAg， and there were positive correlations between degrees of bax expression and HDAg expression（P＜0.05）. Conclusions　The distribution and the expression of bax and HDAg are significantly correlated with the activity of inflammation and the severity of the liver damage， and HDV infection may induce the expression of bax in the hepatocytes，and hepatocyte apoptosis mediated by bcl-2／bax may play an important role in the liver cell injury by HDV infection.

Objective To study the interventional therapeutic methods in Budd Chiari syndrome (BCS) complicated with thrombosis. Methods Eighteen patients of BCS complicated with thrombosis, including 2 cases of hepatic vein (HV) occlusion and 16 cases of inferior vena cava (IVC) occlusion, were treated. Therapeutic methods were anti coagulation with Co Danshen and aspirin in 10 cases or the anti coagulation and thrombolysis with urokinase in 8 cases before operation, treatment with PTA and stent during operation,and thrombolysis with urokinase and the anti coagulation after operation. Results Technical success was achieved in all patients without serious complications. The mean blood pressure in IVC dropped from (31 82?0 52)cm H 2O(1 cm H 2O= 0 098 kPa) to (18 17?0 38)cm H 2O immediately after the procedure. The blood pressure in HV dropped from 42 cm H 2O and 41 cm H 2O to 15 cm H 2O and 16 cm H 2O, respectively. All 18 cases were followed up for an average of 38 months (range 6-72 months). The main symptoms and signs completely disappeared in 12 cases and partially alleviated in 6 cases. Conclusion The interventional treatment of BCS complicated with thrombosis was a safe and effective method.

Background and purpose: Peroxiredoxin Ⅱ (PrxⅡ) has the activity of peroxidase. The relevant studies found it played an important role in gastric cancer. This study aimed to investigate the expression of PrxⅡ in human gastric cancer tissues and cells, analyze its relationship with clinicopathological characteristics, and explore the relationship between PrxⅡ and the prognosis and the development of gastric cancer. Methods: The expression of PrxⅡmRNA and protein in gastric cancer tissues and the paired adjacent normal tissues from 45 patients was detected by real-time fluorescent quantitative polymerase chain reaction (RTFQ-PCR) and Western blot. The same methods were used to detect the expression of PrxⅡ mRNA and protein in GES-1, MGC-803, MKN-45 and MKN-28. Tissue mi-croarray and immunohistochemistry were used to detect the expression of PrxⅡ protein in gastric cancer tissues and the paired adjacent normal tissues from 116 patients. The relationship between the results and clinicopathological char-acteristics was analyzed. The prognosis was analyzed. Results: According to results of RTFQ-PCR and Western blot, we found that PrxⅡ mRNA and protein in gastric cancer tissues were significantly higher than that in adjacent normal tissues (P<0.05). PrxⅡ mRNA and protein in gastric cancer cells were higher than that in normal gastric cells (P<0.01).Immunohistochemistry revealed that the expression of PrxⅡ protein in gastric cancer tissues (76.7％) was also significantly higher (P<0.01) than that in adjacent normal tissues (30.1％). The expression of PrxⅡ protein is significantly related to tumor size, histological differentiation, depth of invasion, TNM stage and lymph node metastasis (P<0.05), but had no significant relationship with the gender, age, tumor location and distant metastasis. Survival in patients with higher PrxⅡ expression significantly shorter than in those with lower expression (P<0.01). PrxⅡ is an independent prognostic factor of gastric cancer (P<0.05). Conclusion: PrxⅡ promotes the development of gastric cancer. It is one of the adverse prognostic factors of gastric cancer and may serve as a new therapeutic target for gastric cancer.
