RESUMO
Objective To dynamically observe the developing process and characteristics of the chronic intra-hepatic hyperplastic nodule to small hepatoma with ultrasound,and to evaluate the value of ultrasound in the diagnosis of small hepatoma.Methods One hundred twenty-two chrome hepatitis cases with HBsAg(+),HBcAb(+)and HBeAg(+)were prospectively examined by two-dimensional ultrasound and three-dimensional reconstruction.Characteristics and diagnostic accuracy of two-dimensional ultrasound and three-dimensional reconstruction were compared with the results of hepatic biopsy.Results Thirty-four of 122 patients developed small hepatoma.The duration between hepatic fibrosis and liver cirrhosis was (6.30±2.31)years,and time of hepatoma changed from liver cirrhosis was (8.01±2.10) years.The intrahepatic hyperplastic nodule,shape of small hepatoma and relationship between tumor and ambient tissue were displayed clearly with three-dimensional ultrasound,and the number of detection with threedimensional ultrasound was much higher than that of two-dimensional ultrasound significantly.Conclusions Dynamic ultrasound examination of the echogenicity change of chronic hepatic lesion caused by HBV is useful for early detection of small intra-hepatic nodule,three-dimensional ultrasound reconstruction may enhance the accuracy in diagnosing small hepatoma.
RESUMO
Objective To investigate correlation between HLA classⅡ molecules and the different outcome of viral hepatitis B. Methods Thirty patients with chronic hepatitis B and 56 subjects who had spontaneously recovered from HBV infection in Zhejiang district were enrolled in this investigation. HLA classⅡ molecule types and their alleles were determined by PCR ssp. Results HLA DR12 was found in 21 of 56 subjects recovered from hepatitis B (38%), compared to 3 of 30 patients with chronic hepatitis B (10%, rr 0.19; P corr
