摘　　要：Objective：The present mini-review updated the progress in methodologies based on using liver biopsy.Data Sources：Articles for study of liver fibrosis,liver biopsy or fibrosis assessment published on high impact peer review journals from 1980 to 2014.Study Selection：Key articles were selected mainly according to their levels of relevance to this topic and citations.Results：With the recently mounting progress in chronic liver disease therapeutics,comes by a pressing need for precise,accurate,and dynamic assessment of hepatic fibrosis and cirrhosis in individual patients.Histopathological information is recognized as the most valuable data for fibrosis assessment.Conventional histology categorical systems describe the changes of fibrosis patterns in liver tissue; but the simplified ordinal digits assigned by these systems cannot reflect the fibrosis dynamics with sufficient precision and reproducibility.Morphometric assessment by computer assist digital image analysis,such as collagen proportionate area （CPA）,detects change of fibrosis amount in tissue section in a continuous variable,and has shown its independent diagnostic value for assessment of advanced or late-stage of fibrosis.Due to its evident sensitivity to sampling variances,morphometric measurement is feasible to be taken as a reliable statistical parameter for the study of a large cohort.Combining state-of-art imaging technology and fundamental principle in Tissue Engineering,structure-based quantitation was recently initiated with a novel proof-of-concept tool,qFibrosis.qFibrosis showed not only the superior performance to CPA in accurately and reproducibly differentiating adjacent stages of fibrosis,but also the possibility for facilitating analysis of fibrotic regression and cirrhosis sub-staging.Conclusions：With input from multidisciplinary innovation,liver biopsy assessment as a new ＂gold standard＂ is anticipated to substantially support the accelerated progress of Hepatology medicine.Objective：The present mini-review updated the progress in methodologies based on using liver biopsy.Data Sources：Articles for study of liver fibrosis,liver biopsy or fibrosis assessment published on high impact peer review journals from 1980 to 2014.Study Selection：Key articles were selected mainly according to their levels of relevance to this topic and citations.Results：With the recently mounting progress in chronic liver disease therapeutics,comes by a pressing need for precise,accurate,and dynamic assessment of hepatic fibrosis and cirrhosis in individual patients.Histopathological information is recognized as the most valuable data for fibrosis assessment.Conventional histology categorical systems describe the changes of fibrosis patterns in liver tissue; but the simplified ordinal digits assigned by these systems cannot reflect the fibrosis dynamics with sufficient precision and reproducibility.Morphometric assessment by computer assist digital image analysis,such as collagen proportionate area （CPA）,detects change of fibrosis amount in tissue section in a continuous variable,and has shown its independent diagnostic value for assessment of advanced or late-stage of fibrosis.Due to its evident sensitivity to sampling variances,morphometric measurement is feasible to be taken as a reliable statistical parameter for the study of a large cohort.Combining state-of-art imaging technology and fundamental principle in Tissue Engineering,structure-based quantitation was recently initiated with a novel proof-of-concept tool,qFibrosis.qFibrosis showed not only the superior performance to CPA in accurately and reproducibly differentiating adjacent stages of fibrosis,but also the possibility for facilitating analysis of fibrotic regression and cirrhosis sub-staging.Conclusions：With input from multidisciplinary innovation,liver biopsy assessment as a new ＂gold standard＂ is anticipated to substantially support the accelerated progress of Hepatology medicine.
