Objective:
To construct an off-line hybrid bioartificial liver supporting system with human liver cell line, and study it's effect on the plasma from patients with liver failure.
Methods:
We established the bioreactor using Psu-2s (Fresenius) cultured with Hep G2 cell transfected with human augmenter of liver regeneration (hALR) gene, then constructed a hybrid bioartificial liver supporting system, at last using the bioartificial liver support system to purify the plasma treated 2 hours with serum bilirubin absorbent, separated from acute on chronic liver failure patients infected by hepatitis B virus.
Results:
Bioreactor was successful constructed. The cell viability in perigastrum of bioreactor is 85.2% and cell propagated rapidly. Before and after treating with bilirubin absorbent, serum total bilirubin was (176.19 +/- 54.14) micromol/L and (50.1 +/- 16.85) micromol/L respectively (P = 0.0002). While there were no significance difference in the level of albumin, urea and glucose. At the begin and end of treatment with bioartificial liver, serum total bilirubin was (50.10 +/- 16.85) micromol/L and (30.27 +/- 15.02) micromol/L respectively (P = 0.000), the urea and albumin increased, urea has significantly difference, but the change of albumin hasn't.
Conclusion:
The off-line hybrid bioartificial liver supporting system with human liver cell line were builded successfully and have synthesis and metabolism functions for acute on chronic liver failure patients.
