AIM: To evaluate the prophylactic efficacy of hepatitis B immunoglobulin(HBIG) in combination with different nucleos(t)ide analogues.METHODS: A total of 5333 hepatitis B surface antigenpositive patients from the China Liver Transplant Registry database were enrolled between January 2000 and December 2009. Low-dose intramuscular(im) HBIG combined with one nucleos(t)ide analogue has been shown to be very cost-effective in recent reports. Hepatitis B virus(HBV) prophylactic outcomes were compared based on their posttransplant prophylactic protocols [group A(n = 4684): im HBIG plus lamivudine; group B(n = 491): im HBIG plus entecavir; group C(n = 158): im HBIG plus adefovir dipivoxil]. We compared the related baseline characteristics among the three groups, including the age, male sex, Meld score at the time of transplantation, Child-Pugh score at the time of transplantation, HCC, pre-transplantation hepatitis B e antigen positivity, pre-transplantation HBV deoxyribonucleic acid(HBV DNA) positivity, HBV DNA at the time of transplantation, pre-transplantation antiviral therapy, and the duration of antiviral therapy before transplantation of the patients. We also calculated the 1-, 3- and 5-year survival rates and HBV recurrence rates according to the different groups. All potential risk factors were analyzed using univariate and multivariate analyses.RESULTS: The mean follow-up duration was 42.1 ± 30.3 mo. The 1-, 3- and 5-year survival rates were lower in group A than in groups B(86.2% vs 94.4%, 76.9% vs 86.6%, 73.7% vs 82.4%, respectively, P < 0.001) and C(86.2% vs 92.5%, 76.9% vs 73.7%, 87.0% vs 81.6%, respectively, P < 0.001). The 1-, 3-and 5-year posttransplant HBV recurrence rates were significantly higher in group A than in group B(1.7% vs 0.5%, 3.5% vs 1.5%, 4.7% vs 1.5%, respectively, P = 0.023). No significant difference existed between groups A and C and between groups B and C with respect to the 1-, 3- and 5-year HBV recurrence rates.

AIM:To investigate whether the use of synchronoushepatectomy and splenectomy(HS)is more effective than hepatectomy alone(HA)for patients with hepatocellular carcinoma(HCC)and hypersplenism.METHODS:From January 2007 to March 2013,84consecutive patients with HCC and hypersplenism who underwent synchronous hepatectomy and splenectomy in our center were compared with 84 well-matched patients from a pool of 268 patients who underwent hepatectomy alone.The short-term and longterm outcomes of the two groups were analyzed and compared.RESULTS:The mean time to recurrence was 21.11±12.04 mo in the HS group and 11.23±8.73 mo in the HA group,and these values were significantly different(P=0.001).The 1-,3-,5-,and 7-year disease-free survival rates for the patients in the HS group and the HA group were 86.7%,70.9%,52.7%,and 45.9%and 88.1%,59.4%,43.3%,and 39.5%,respectively(P=0.008).Platelet and white blood cell counts in the HS group were significantly increased compared with the HA group one day,one week,one month and one year postoperatively(P<0.001).Splenectomy and micro-vascular invasion were significant independent prognostic factors for disease-free survival.Gender,tumor number,and recurrence were independent prognostic factors for overall survival.CONCLUSION:Synchronous hepatectomy and hepatectomy potentially improves disease-free survival rates and alleviates hypersplenism without increasing the surgical risks for patients with HCC and hypersplenism. 展开更多

AIM: To investigate the correlation between subcellulardaunorubicin distribution and the multidrug resistancephenotype in drug-resistant cell line SMMC-7721/R.METHODS: The multidrug resistant cell line SMMC-7721/R, a human hepatocellular carcinoma cell line,was established. Antisense oligonudeotides (AS-ODN)were used to obtain different multidrug resistancephenotypes by inhibiting the expression of mdr1 geneand/or multidrug resistance-related protein gene(mrp)using Lipofectamine as delivery agent. Expression ofmdr1 and mrp genes was evaluated by RT-PCR andWestern blotting. Intracellular daunorubicin (DNR)concentration was measured by flow cytometry.Subcellular DNR distribution was analyzed by confocallaser scanning microscopy. Adriamycin (ADM) and DMRsensitivity was examined by MTT method.RESULTS: Low level expression of mdr1 and mrp mRNAsand no expression of P-Glycoprotein(P-gp) andmultidrug resistance-related protein (P190) weredetected in parental sensitive cells SMMC-7721/S, butover-expression of these two genes was observed indrug-resistant cell SMMC-7721/R. The expression ofmdr1 and mrp genes in SMMC-7721/R cells was downregulated to the level in the SMMC-7721/S cells by AS-ODN. Intracellular DNR concentration in SMMC-7721/S cells was 10 times higher than that in SMMC-7721/Rcells. In SMMC7721/S cells intracellular DNRdistributed evenly in the nucleus and cytoplasm, whilein SMMC-7721/R cells DNR distributed in a punctatepattern in the cytoplasm and was reduced in thenucleus. DNR concentration in SMMC-7721/R cells co-transfected with AS-ODNs targeting to mdr1 and mrpmRNAs recovered to 25 percent of that in SMMC7721/Scells. Intracellular DNR distribution pattern in drug-resistant cells treated by AS-ODN was similar to drug-sensitive cell, and the cells resistance index (RI) to DNRand ADM decreased at most from 88.0 and 116.0 to 4.0and 2.3, respectively. Co-Transfection of two AS-ODNsshowed a stronger synergistic effect than separatetransfection.CONCLUSIONS: P-gp and P190 are two membersmediating MDR in cell li 展开更多
