Objective To study the clinical characteristics, diagnosis and treatment of extrahepatic growing hepatocellular carcinoma(HCC). Methods The clinical data of 11 patients with extrahepatic growing HCC were analysed retrospectively. Results The mean diameter of the tumors was (12.4?4.3)cm.All the tumors in the 11 patients had complete capsule formation. The numbers of tumors located in the left, right and caudate lobe of the liver were 6,3 and 2 respectively. Surgical treatment included segmentectomy in 6 cases , lobectomy in 4 cases, and unresectable in 1 case. The 1-, 2-, and 3-year survival rates were 80.1%,62.3%, and 47.6% respectively. Conclusions Although the size of extrahepatic growing HCC is large,the resection rate is high and prognosis is good. The resection of hepatic segments or lobes containing the lesion should be done in radical operation of this tumors.

Objective To evaluate the feasibility and safety of resection of tumors in hepatic centric area. Methods The clinical data of 36 patients with tumors in hepatic centric area treated by resection in our hospital from Jan 1996 to Dec 2001 were retrospectively analyzed. In this series,there were 26 cases of liver cancer and 10 cases of benign tumor. Of the 36 patients,the tumor involved the first porta hepatis in 13 cases, involved the second porta hepatis in 10 , involved the third porta hepatis in 5 , involved both the first and second porta hepatis in 3, and involved both the second and third porta hepatis in 5 cases. Results During the operation, massive hemorrhage occurred in 4 cases(11.1%). Postoperative complications occurred in 11 patients(30.5%),including liver function failure in 1 case (2.7%), biliary fistula in 2 cases (5.5%), pleural effusion in 6 cases (16.7%), subphrenic infection in 1 case (2.7%),and abdominal incisional hernia in 1 case (2.7%). All patients recovered except that one died of acute hepatic failure after the operation. Conclusions Although the surgery for this tumor is quite difficult and risky, if enough attention is paid to the choice of the patient,and the meticulous surgical technique,the operation safety and therapeutic result of the operation could be improved.

Objective To investigate the protective effect of ischemic preconditioning(IP) on liver ischemia/reperfusion(I/R)injury in rats with cirrhosis.Methods Thirty-two SD rats with liver cirrhosis induced by carbon tetrachloride were randomly divided into IP group and Non-IP(NIP) group,according to whether an IP was performed before liver I/R injury or not.The function of liver, superoxide dismutase(SOD),glutathione peroxidase(GSH-PX),malonyldialdehyde(MDA),adenine nucleotide(ATP,ADP,AMP),energy charge(EC),nitric oxide(NO)in liver tissues,the changes in liver histology,and one-week survival rate after the test in both groups were compared.Results Compared with NIP group,the serum AST,ALT ,and LDH and the MDA contents significantly decreased(P
