We investigated the overall situation of LT for BA in mainland China and analyzed their survival outcomes based on data from CLTR. Between January 1996 and December 2013, 509 liver transplants for BA were performed in mainland China and were included in this study. Patients' median age was 9.6 months (range: 4.8-175.2 months). KP was previously performed in 194 cases (38.1%). Grafts from living donors were used in 380 cases (74.7%). Era I (1996.1-2010.12) and era II (2011.1-2013.12) comprised 151 cases (29.7%) and 358 cases (70.3%), respectively. Twenty-five centers had performed at least one liver transplant for children with BA. Centers from Shanghai (197 cases), Tianjin (143 cases) and Beijing (81 cases) involved 82.7% of the 509 cases. One- and five-yr graft survival rates were 84.7% and 72.6%, respectively. Split grafts, center volume <20, GRWR ≥4.0%, and steroid-free immunosuppression regimen were independent risk factors for graft survival. In conclusion, the dramatic expansion of pediatric liver transplant programs in mainland China has enabled improved survival for those children affected by this devastating disease. However, screening of BA in neonates should be emphasized throughout the country to enhance early referrals for KP., (© 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.)

Fibroblast growth factor 21 is a critical circulating adipokine involving in metabolic disorders and various liver diseases. This study was performed to investigate whether FGF21 is also associated with the pathophysiology of biliary atresia. Serum FGF21 levels were measured in 57 BA patients and 20 age matched healthy controls. We also examined hepatic FGF21 mRNA expression and FGF21 protein levels in liver tissues obtained from 15 BA patients undergoing liver transplantation and 5 cases of pediatric donation after cardiac death donor without liver diseases by RT-PCR and Western blotting. Patients with BA showed significantly higher serum FGF21 levels than those without BA (554.7pg/mL [83-2300] vs. 124.5pg/mL [66-270], P<0.05). Patients with BA also had significantly higher FGF21 mRNA and protein levels in hepatic tissues than control subjects. Serum FGF21 expression increased corresponding to the severity of liver fibrosis. Furthermore, serum FGF21 levels dropped significantly in BA patients within 6months after liver transplantation and approached baseline in healthy controls (P>0.05). In vivo, FXR knockout could significantly abrogate cholestasis induced FGF21 expression. FGF21 levels in serum and liver tissue increased significantly in BA patients. In vivo, cholestasis could induce FGF21 expression in FXR dependent manner., (Copyright © 2016 Elsevier Ltd. All rights reserved.)
