Liver transplantation is a valid treatment option for select patients with Hepatocellular Carcinoma HCC and end-stage liver disease. However, in approximately 20% of patients, recurrent HCC is the rate-limiting factor for longterm survival. Despite identification of clinical parameters that may stratify patients at high risk and exhaustive preoperative staging, cancer recurrence is likely the result of microscopic extrahepatic disease. With a desperate donor organ shortage, locoregional ablation techniques and resection are being employed in patients on the waiting list to serve as a bridge to OLT. Further more, some have advocated aggressive surgical resection of isolated metastasis in both the liver and extrahepatic viscera. Whether these creative strategies confer a survival advantage is unknown, requiring longterm follow-up to determine their efficacy.

Objective: To qualitatively identify 5 chlorin metal complexes which had similar structures. Methods: The compounds were identified by the convolution curve transformation technology and computer information process technology. Results: The results were demonstrated by match comparison and three dimensional differential diagram of convolution spectra. Five chlorin metal complexes were identified satisfactorily and 10 nonidentity identification results were acquired. Conclusion: The convolution spectrum method is simple and feasible for the identification of the compounds which have similar structures. [

Objective To explore the relationship between respiratory viruses infection and the episode of steroid responsive simple nephrotic syndrome(SRSNS).Methods Thirty-eight children with SRSNS were selected,including the active stage group(n=28)and the remission group(n=10).The urine from 18 cases of nephritic nephrosis,16 cases of bronchiolitis,15 cases of secondary glomerular diseases and 15 cases of healthy children were served as controls.By using the method of reverse transcriptase-polymerase chain reaction(RT-PCR)and alkaline phosphoesterase-anti alkaline phosphoesterase enzyme-linked assay(APAAP),viral genes and antigens in urine were assayed,respectively.Results The positive rate of detecting viruses in the active stage group of SRSNS children was higher than that in the remission group and the other control groups(Pa

The optimum convolution spectra of β-galactosidase and the linear equation of Qj=1.906×10-2＋4.946×10-3 C＋1.909×10-4 C2,r=1.0000 under the best condition were established by the convolution spectrum method.Based on the chromogenic substrate o-nitrophenyl-β-galactoside,a method for the determination ofβ-galactosidase activity in the COS-1 extraction sample which had been transfected transiently expression vector of β-galactosidase was determined by using the convolution curve transformation technology.The convolution spectrum method was compared with the absorption method and the result was satisfactory.The method was simple,convenient,fast and valuable to the biochemical analysis.

Objective To explore the perioperative experiences of congenital heart disease in infants.Methods From Jan.2000 to Aug.2006,109 patients with congenital heart disease were operated in our department,their clinical data were retrospectively collected and analyzed.The patients′ age ranged from 31 days to 3 years old (13.6 months).The body weight ranged from 2.1 to 16 kg (8.6 kg).Ninety-three patients were operated under hypothermic anaesthesia with cardiopulmonary bypass(CPB).Sixteen patients underwent deep thermal and low flow CPB.Ultrafiltration was used in 62 patients.Results There were 8 deaths and the operative mortality was 7.3%,4 cases caused by low output syndromeclos(LOS),3 cases caused by pulmonary hypertension and 1 case caused by lung intection.The morbidity was in 25 cases(22.9%),the main complications were LOS in 6 patients and respiratory complications in 18 patients,hydropericardium in 1 case,respectively.Conclusion To improve the operative and CPB technique,and to improve the skills of the postoperative managements of LOS and respiratory complications are the main points in the success of the cardiac operation in infants.

Objective To evaluate the effect of laparoscopy in treatment of renal cysts.Methods Twenty- eight and thirty-five patients with renal cysts were performed with transperituneal and retroperitonel laparoscopy,re- spectively.Results A total of 62 patients were treated successfully,the average operation time was 60 minutes,no complications presented,and there was no recurrence in follow-up.Conclusion Laparoseopy survey had the advan- tages of less trauma and fewer complications and rapid recovery in treatment of renal cysts,which was suggested for clinical applications.

To explore the impact of the history of infection by the influenza A virus subtype H1N1 on secondary infection by the influenza A virus subtype H9N2, pigs non-infected and pre-infected with H1N1 were inoculated with H9N2 in parallel to compare nasal shedding and seroconversion patterns. Unlike pigs without a background of H1N1 infection, nasal shedding was not detected in pigs pre-infected with H1N1. Both groups generated antibodies against H9N2. However, levels of H1N1 antibodies in pigs pre-infected with H1N1 increased quickly and dramatically after challenge with H9N2. Cross-reaction was not observed between H1N1 antibodies and H9N2 viruses. These findings suggest that circulation of the H1N1 virus might be a barrier to the introduction and transmission of the avian H9N2 virus, thereby delaying its adaptation in pigs.
