ObjectiveTo study the effects of membrane molecular weight cut off on a novel bioartificial liver(BAL) system.MethodsHealthy beagles underwent 6-hour treatment with a BAL containing membrane with 200 kDa retention rating or 1200 kDa retention rating.The functional changes and cell viability were characterized.ResultsHepatocyte performance levels such as albumin secretion,urea synthesis and viability were significantly higher in the 200 kDa retention rating group when compared with the 1200 kDa retention rating group (P＜0.05).Significant levels of canine proteins were detected in the BAL medium from the 1200 kDa retention rating group.Fluorescence microscopy further verified that heavy deposition of canine IgG,IgM and complement (C3) on co-culture cells were obtained after BAL treatment in the 1200 kDa retention rating group.ConclusionsSmall membrane molecular weight cut off of BAL could reduce the transfer of xenoreactive antibodies into the BAL medium and improved the performance of the BAL.

Objective To investigate the safety and therapeutic effects ot a novel multi-layer flat-plate bioartificial liver (BAL) for patients with liver failure.Methods Thirty-eight patients with liver failure from Dec.2010 to Dec.2011 were treated with a novel BAL based on multi-layer flatplate bioreactor and the co-cultured cells of the porcine hepatocytes and mesenchymal stem cells.A total of 48 treatments was performed,4 h each time.The clinical signs and symptoms,liver function,ammonia,coagulation function and complete blood count were evaluated before,during and after the treatment.DNA in the collected PBMCs was extracted for PCR with PERV specific primers and the porcine specific primer Sus scrofa cytochrome B.The RT activity was detected as well.Levels of xenoantibodies (IgG,IgM) were determined by using ELISA kit. Titers of complement were quantified by CH50 kit.Results All treatment procedures were completed successfully without any adverse reaction. All samples presented negative PERV DNA and RT activity. The levels of antibodies were similar before and after treatment.Treatment was associated with a temporary decline in levels of complement,and then the levels were recovered quickly.The clinical symptoms such as acratia,anorexia and abdominal distension were improved.The stage of hepatic encephalopathy in 16 patients was decreased. The liver function and ammonia was reduced disproportionately. Seven patients in all were bridged to liver transplantation,2 patients died and 2 patients gave up the treatment,and the others were turned better.After the outcome judgment according to the standard developed by the Artificial Liver Group,and Chinese Association of Infectious and Parasitic Diseases,there were 9 patients with clinical healing,25 patients with improvement and 4 patients with no effect,and the cure-improvement rate was 89.5％.Conclusion The novel multi-layer flat-plate BAL could be used as a safe and effective therapy for patients with liver failure.

Objective To investigate the influence of membrane molecular weight cut off in our bioartificial liver(BAL)system.Methods Beagle dogs were used for a model of acute liver failure through D-galactosamine administration.The acute liver failure Beagles were divided into two groups by the membrane molecular weight cut off.Group A was treated with BAL containing 200 kDa retention rating membrane.Group B was treated with BAL containing 1200 kDa retention rating membrane.Each group underwent two six-hour BAL treatments that were performed on day 1 and day 21.BAL medium were examined and levels of IgG,IgM,and complement hemolytic unit of 50％(CH50)antibodies were measured in all Beagles and.Results BAL treatment was associated with a significant decline in levels of CH50.1200 kDa group experienced a significant increase in levels of IgG and IgM after two BAL treatments.Significant levels of canine proteins were detected in BAL medium from 1200 kDa group.Conclusions Xenogeneic immune response in the BAL system was influenced by membrane molecular weight cut off.

Objective To evaluate the application value of the blastocysts derived from non-pronucleus (0PN) zygotes by the good quality blastocyst formation rate and the clinical outcomes of frozen-thawed blastocyst transfers. Methods The good quality blastocyst formation rate derived from 0PN zygotes was compared with that derived from2 pronucleus(2PN)zygotes in in vitro fertilization(IVF)or intracytoplasmic sperm injection (ICSI) cycles from January 2015 to December 2016. In addition, the clinical pregnancy, embryo implantation and live birth rates of frozen-thawed blastocyst transfers with blastocysts derived from 0PN and 2PN zygotes were analyzed on corresponding dates. Results (1)In IVF cycles, the high quality blastocysts formation rate of 2PN embryos was significantly higher than that of 0PN (46.64% versus 42.42%, P<0.01). In ICSI cycles, the high quality blastocysts formation rate of 2PN embryos was markedly higher than that of 0PN(41.96% versus 21.73%, P<0.01).(2)In frozen-thawed embryo transfer cycles for IVF, the clinical pregnancy, implantation and live birth rates of D5 0PN blastocysts were significantly higher than those of D6 2PN(52.64% versus 46.78%, 49.91% versus 41.20%, 46.54% versus 39.56%, all P<0.05), however, the abortion and newborn abnormal rates of D5 0PN blastocysts were lower than those of D6 2PN blastocysts(17.37% versus 23.36%, 1.31% versus 4.21%, both P<0.05); the clinical pregnancy, implantation and livebirth rates of D5 2PN blastocysts were significantly higher than those of D5 0PN(59.73% versus 52.64%, 55.95% versus 49.91%, 53.03% versus 46.54%, all P<0.05), but newborn abnormal rate was a little higher than that of D5 0PN(3.90% versus 1.31%, P<0.05);the clinical pregnancy, implantation and live birth rates of D5 2PN blastocysts were significantly higher than those of D6 2PN(59.73% versus 46.78%, 55.95% versus 41.20%, 53.03% versus 39.56%, all P<0.05), and the abortion rate of D5 2PN blastocysts was lower than that of D6 2PN blastocysts(18.23% versus 23.36%, P<0.05). Conclusions Although the blastocysts derived from 0PN could be transffered, the blastocysts derived from 2PN zygotes are preferred in all cycles. In IVF cycles, the good quality blastocysts derived from 2PN or 0PN zygotes will be transferred.

Objective To study the mutation of FLCN gene in Chinese patients with sporadic and familial primary spontaneous pneumothorax. Methods A complete genetic analysis of FLCN by use of SSCP-PCR was performed in 102 unrelated Chinese patients with isolated PSP. Results Three novel mutations (c. 924_926del, c. 1611_1631del and c. 1740C.T) and a previously reported mutation (c. 1733insC) were identified in five familial and five sporadic PSP patients. Of the 21 family members of patients with PSP including 3 previous considered as sporadic, 4 ( 19% ) had history of at least one episode of PSP and 9 (43% ) were FLCN mutant carriers without PSP. Seven of the nine (78% ) mutant carriers had pulmonary cysts detected by high-resolution computed tomography ( HRCT) . Although c. 924_926del and c. 1611 _1631 del were found in eight patients from the same geographic district, haplotype analysis demonstrated that they did not share the same affected haplotype,thus excluding common ancestry. Conclusion This study first demonstrates that FLCN mutation contributes to not only familial but also apparently sporadic' patients with isolated PSP. It suggests that mutation analysis and HRCT scan may be recommended for first-degree family members of PSP patients with FLCN mutations, irrespective of their family history status of PSP.
