In order to explore the expression level and diagnostic value of TGF-1 and VEGF in BA hepatic fibrosis, the general clinical data of 62 children with biliary atresia admitted to our hospital from March 2016 to 83 Months 2019 were collected, and TGF-1 and VEGF were detected and analyzed, to explore the expression level and diagnostic value of TGF-1 and VEGF in biliary atresia liver (BA) fibrosis. The gene discussed is VEGFA; the disease is Hepatic fibrosis.
