[Alteration on hepatocyte nuclear factor 1α expressions and significance in the process of occurrence and development of liver inflammation and fibrosis in patients with chronic hepatitis B].

To investigate the relationship between the expression of hepatocyte nuclear factor-1 α (HNF-1α) and the occurrence and development of liver inflammation and fibrosis in liver tissues of patients with chronic hepatitis B. Sixty-four patients with chronic hepatitis B who were diagnosed and treated in our hospital from 2011 to 2018 were selected. All patients underwent ultrasound-guided aspiration liver biopsy. The pathological results of liver biopsy were collected for inflammation grading and fibrosis staging. The liver puncture biopsies was collected by paraffin sectioning. The expression of HNF1α in the liver tissue was detected by immunohistochemical staining. Mantel-Haenszel (2) test was used for bidirectional ordered grouping data, and Spearman's rank-correlation test was used for rank correlation analysis. There were varying degrees of inflammatory necrosis and fibrosis in the liver tissues of patients with chronic hepatitis B. There was a linear relationship between the expression of HNF1α and the level of inflammation in liver tissues ( (2)(MH) = 40.70, < 0.05). The expression of HNF1α in liver tissues of patients with chronic hepatitis B was decreased with the increase of liver inflammation. The expression intensity of HNF1α was negatively correlated with the inflammation grade ((s) = -0.815, < 0.05). There was a linear relationship between the expressions of HNF1α and the degree and stage of liver fibrosis ( (2)(MH) = 31.95, < 0.05). The expression level of HNF1α in liver tissue was gradually decreased with the aggravation of liver fibrosis. The expression intensity of HNF1α was negatively correlated with fibrosis stage ((s) = -0.713, < 0.05). HNF1α is closely related to the occurrence and development of liver tissue inflammation and fibrosis, and is expected to be a sensitive indicator for evaluating the level of liver tissue inflammation and fibrosis in patients with chronic hepatitis B. In addition, its down-regulation may be involved in the process of occurrence and development of liver inflammation and liver fibrosis, and may become a new target for the treatment of chronic hepatitis B.
