Abstract: Objective To investigate the level of liver fibrosis by detecting liver fibrosis indexes and INF-γ
through ICG secretion test comprehensively. Methods Total of 129 patients with liver fibrosis and cirrhosis
in the First Affiliated Hospital of Third Military Medical University from January 2012 to October 2013
were selected as the experimental group, and 19 healthy people as the control group. Liver fibrosis markers
and INF-γ were detected. The pathological diagnosis of liver biopsy was performed to determine the level
of liver fibrosis. The K value and R15 of the experimental group were detected by ICG secretion test. SPSS
17.0 software was used to analyze the data. Results The K value and R15 had significant differences in five
different degrees of fibrosis (S 0 , S 1 , S 2 , S 3 and S 4 ) pathological type; liver fibrosis markers showed significant
differences in S0, S1, S2, S3 groups, and there was no significant difference between S4 and S3 group.
