RESUMO
Summary: To investigate the difference in expression of hTERT gene between HbsAg-positive human hepatocellular carcinoma (HCC) and HbsAg-negative HCC and to explore the relationship between HBV infection and hTERT gene expression in HCC. The expression of hTERT protein in 30 cases of HbsAg positive HCC and 17 cases of HbsAg negative HCC was detected by immunohistochemistry (SP method), and the expression of hTERT mRNA was analyzed by reverse transcription polymerase chain reaction (RT-PCR). t-test, Chi-squared test and cochran- armitage trend test were used to see whether there was an interrelation between HBsAg and hTERT gene in HCC. The expression of hTERT protein was mostly located in plasm and occasionally in the nucleus of liver cancer cells. The positive rate of hTERT protein and hTERT mRNA in HbsAg positive HCC- 93.33 % (28/30) and 83.33 % (25/30) respectively which were much higher than those in HbsAg negative HCC- 52.94 % (9/17), 47.06 % (8/17) (P<0.01) respectively. HbsAg is related to hTERT gene expression in human hepatocellular carcinoma. The hTERT gene activated by the efficacious ingredient of HBV may play an important role in hepatocellular transformation and carcinogenesis.
RESUMO
Objective To study the expression of integrin ?1 in hepatocellular carcinoma (HCC) and its significance. Methods Integrin ?1 expression was detected in 38 cases of HCC, 8 cases of hepatic cirrhosis (HC) and 7 cases of normal liver tissues(NL) using immunohistochemical SP method. The relationship between the integrin ?1 expression and HCC clinico-pathological features was analyzed. Results The positive rate of integrin ?1 expression in the HCC was much higher than that in the HC and NL tissues (P
RESUMO
Objective To explore the expression of tenascin in hepatocellular carcinoma (HCC). Methods With the method of immunohistochemical staining, specimens from 42 HCC patients, 10 hepatic cirrhotics and 7 normal liver controls were studied. The relationship between the tenascin expression and pathological features as well as microvessel density (MVD) was evaluated. Results The expression of tenascin in the HCC tissues was much higher than that in the non-HCC tissues ( ? 2=4.15, P
RESUMO
Objective To study the pathologic feature and rational diagnosis and treatment of Mirizzi Syndrome. Method The clinical data of 43 cases treated by surgery were retrospectively analysed. Results All the 43 cases underwent operation, including partial cholecystecomy in 8 cases, cholecystectomy in 16cases , cholecystectomy plus common bile duct exploration with T tube drainage in 9 cases, choledochojejunostomy in 10 cases. Of the 43 cases, 36 cases were followed up for 1～5 years. Of them, 29 cases were in excellent, 6 cases in good and 1 case in poor. Conclusions The pathologic type of Mirizzi Syndrome is variant. It is difficult to make a definite diagnoses before operation. So vary imaginal technique should be adopted. Different operative procedures should be used according to patients' pathologic type.
