Objective: To observe p53 expression in liver tissue of patients with chronic hepatitis B and its influencing factors.
Methods: 17 cases HBeAg-negative chronic hepatitis B patients and 31 cases HBeAg-positive chronic hepatitis B patients were divided into 2 groups.
Results: (1) HBeAg-negative chronic hepatitis B patients were older, mostly male and HBV DNA lower. These three indicators between two groups patients appeared statistical difference. Serum markers were no statistical difference between two groups patients except Glo. (2) Pathological inflammation and fibrosis Staging were no statistical difference between two groups patients. p53 expression positive rate and p53 expression semi-quantitative scoring in liver tissue were no statistical difference between the two groups. (3) Logistic regression analysis showed that only liver fibrosis staging (S) is a risk factor for p53 expression. Compared with the S0-1, p53 expression increased by 3.9 times the rate of positive in S > or = 2.
Conclusion: Liver fibrosis staging in patients with chronic hepatitis B is a risk factor for p53 positive expression in liver.
