Objective To evaluate the efficacy and safety of using basiliximab in place of a corticosteroid for immunosuppression following liver transplantation for hepatocellular carcinoma (HCC) in Chinese patients.Method The records of 178 patients with HCC who underwent orthotopic liver transplantation from January 2003 to December 2009 were retrospectively reviewed.All patients received immunosuppression therapy that contained either basiliximab (n =78) or steroids (n =100) in addition to tacrolimus and mycophenolate mofetil.Assessments included complications related to liver transplantation,occurrence of steroid side effects,recurrence of HCC,and patient and graft survival.Results A smaller proportion of patients receiving basiliximab than steroids experienced de novo diabetes (38.7％ vs.91.0％,respectively) or long-term de novo diabetes mellitus (4.0％ vs.30.3％,respectively) (both,P＜0.0001).The median overall and disease free survival was similar between basiliximab (50.8 months and 19.6 months,respectively) and steroid treated patients (64.2 months and 23.8 months,respectively).The 5-year overall survival and disease free survival rate was also similar between the basiliximab (42.5％ and 38.9％,respectively) and steroid (50.5％ and 39.2％) groups (all,P＞0.730).However,in patients who met the Milan criteria basiliximab was associated with greater 5 year overall survival rate than steroid therapy (88.9％ vs.57.4％,respectively,P =0.022).Conclusion It revealed that the non-steroid treatment does not increase the incidence of acute rejection but also can decrease the incidence of de novo diabetes in the patients with HCC following liver transplantation and prolong the survival time of patients who met the Milan criteria.

Objective　To study chemotherapy sensitivity and apoptosis in tumor cell line.Methods　Two different human colon carcinoma cell lines, LoVo and Ls-174-t were incubated with DDP,MMC,5-FU，EPI at various peak plasma concentrations (PPC), 1/10PPC，1/5PPC，5PPC and 10 PPC. Apoptosis was detected by FACScan and TUNEL technique after 24 hours and 48 hous. Cell growth inhibition rates were assessed by MTT, DNA ladder were examined by agarose electrophoresis.Results　At 48 hours, the highest cellular apoptosis rates were observed with PPC which was assessed by FACScan technique. There was a positive linear correlation between apoptosis assessed by TUNEL technique and growth inhibition rates of cells determined by MMT(P＜0.05).Conclusion　Using Annexin-V-Fluos staining FACScan technique to assess apoptosis of tumor cells is an exploring and useful method which can be used to choose both kinds and doses of chemotherapeutic drugs.

Objective To evaluate the outcome of liver transplantation (LT) or combined liver-kidney transplantation (CLKT) for acute-on-chronic liver failure (ACLF) patients with renal dysfunction.Method From January 2001 to December 2009,133 patients underwent LT for ACLF at our center.Among them,30 had both ACLF and renal dysfunction.Of the 30 patients,12 underwent CLKT for end-stage renal disease (ESRD),and the other 18 with hepatorenal syndrome type 1 (HRS1) underwent LT alone.Their clinical data were reviewed and their survival outcomes were compared.Result The median model for end-stage liver disease scores (MELD) of the patients with ACLF were 28.133 patients received deceased donor liver grafts and 12 patients also received the same deceased donor kidney grafts,The hospital mortality rate was 21.8％ for all patients with ACLF.The 5-year survival rates were 72.8％ for patients without renal dysfunction and 70％ for patients with renal dysfunction.The curative effectiveness of the patients with ESRD who underwent CLKT was better than that of the patients without renal dysfunction or the patients with HRS1 who underwent LT alone.Conclusion LT alone improved renal function in most patients with HRS1.Simultaneous liver-kidney transplantation is an excellent strategy in patients with both ACLF and ESRD.It provides protection to kidney allograft in liver-based metabolic diseases affecting the kidney.

Purpose:To study the relationship between Fas/FasL expression and apoptosis of colon adenocarcinoma cell lines induced by chemotherapeutic drugs and to screen out hypersensitive drugs. Methods:Colon adenocarcinoma cell lines LS174T and LoVo were incubated respectively in cultural media with DDP,MMC,5 FU and EPI at concentrations of PPC(plasma peak concentration),1/10 PPC,1/5 PPC,5 PPC and 10 PPC. Fas/FasL expression and apoptosis were assessed by FACScan, and DNA ladder was examined by agarose gel electrophoresis. Results:In LS174T cells, Fas expression and apoptosis of DDP group, MMC group and EPI group reached their highest peaks at 1/5 PPC or PPC,and Fas expression and apoptosis were positively correlated by relativity analysis. There was no significant correlation between Fas expression and apoptosis in LoVo cells. Conclusions:We could find out hypersensitive drugs and their appropriate dosage according to apoptosis, partly according to Fas expression. The different apoptosis paths between LS174T cells and LoVo cells demonstrate the importance of individualized selection of chemotherapeutic drugs.

Objective To investigate the causes of acute renal failure(ARF)after orthtopic liver transplantation(OLT)in patients of acute liver failure(ALF)and the effects of systemic therapy based on continuous renal replacement(CRRT).Methods Clinical data of 412 patients who underwent liver transplantations between January 2001 and June 2006 were analyzed retrospectively (all the cases were followed up to June 2007).According to UNOS grading scale,54 patients were of acute liver failure(UNOS 1 and 2A).Posttransplant ARF developing in 17 cases underwent a systemic therapy based on CRRT as well as anti-rejection,anti-infection and nutrition support.The perioperative courses,complications,causes of death and follow up results were analyzed.Results There were no severe complications during CRRT.Perioperative mortality was 5.4%and 58.8%in patients without ARF and those with ARF respectively.the rate of complications was 35.1%vs 100%.1 year survival rate Was 89.2% vs 41.2%.3 year survival rate was 81.1% vs 41.2%.Condusions The effect of surgery mainly depends on the function of liver and other vital organs.The ALF recipients suffered from a high perioperative mortality,especially those with posttransplant ARL.The systemic therapy based on CRRT benefits patients with postoperative ARF.

OBJECTIVEEndogenous hydrophobic bile acids may be a pathogenetic factor of biliary complications after orthotopic liver transplantation (OLT).This study was designed to investigate the effects of hydrophilic ursodeoxycholic acid (UDCA), when administered early after OLT, on serum liver tests and on the incidence of biliary complications.

METHODSA total of 112 adult patients undergoing OLT were randomly assigned to one of two groups for receipt of UDCA (13 to 15 mg/kg/d for 4 weeks, n=56) or a placebo (n=56). All patients underwent serum liver testing and measurement of serum bile acids during the 4 weeks following OLT.Patients with T-tube underwent measurement of biliary bile acids during the 4 weeks following OLT.Biliary complications, as well as patient and graft survival rates, were analyzed during the follow-up period (mean of 65.6 months).

RESULTSAt post-OLT days 7, 21 and 28, the UDCA-treated patients showed significantly lower levels of alanine aminotransferase, aspartate aminotransferase and gamma glutamyl transpeptidase (all P less than 0.05).In addition, the UDCA-treated patients showed significantly lower incidence of biliary sludge and casts within the first year post-OLT (3.6% vs.14.3%; x2=3.953, P=0.047). However, there were no significant differences for the incidence of other biliary complications at post-OLT years 1, 3 and 5.The graft and patient survival rates were also similar between the two groups.

CONCLUSIONUDCA, when administered early after OLT, improves results from serum liver tests and decreases the incidence of biliary sludge and casts within the first postoperative year.
