Expression and role of augmenter of liver regeneration in patients with hepatic failure / 中华肝脏病杂志

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the expression and role of augmenter of liver regeneration (ALR) in hepatic failure.</p><p><b>METHODS</b>ALR polyclonal antibody was prepared and purified. Serum ALR in patients with hepatic failure, chronic hepatitis B and healthy persons were quantified by ELISA, ALR mRNA in hepatic tissues were quantified by real-time PCR.</p><p><b>RESULTS</b>Different serum ALR levels foreshowed different outcomes for hepatic failure patients The liver function was restored in 6 patients with higher ALR level [(1613.5+/-369.6) pmol/ml], and the liver function was deteriorated in 12 patients with lower ALR level [(462.3+/-235.8) pmol/ml]. ALR level in patients with chronic hepatitis B [(969.2+/-332.5) pmol/ml] was similar to that in healthy persons [(806.9+/-240.8) pmol/ml]. ALR mRNA level in hepatic failure patients receiving OLT (103.45 copies/microl) was lower than that in chronic hepatitis B patients (104.37 copies/microl) and healthy persons (104.31 copies/microl), ALR mRNA level in chronic hepatitis B and healthy persons was similar.</p><p><b>CONCLUSION</b>These findings suggest serum ALR level reflected ALR mRNA level in liver and is helpful in estimating the survival time of patients with hepatic failure.</p>
