Antibody against hepatitis C virus (anti-HCV) was tested in 658 cases of hepatitis and liver diseases with ELISA, ninety of these cases were positive, with a total infection rate of 13.68% (90/658). The positive rate of anti-HCV was highest in patients with chronic severe hepatitis (33.78%) and CAH accompanied by cirrhosis of liver(31.58%). The infection rate in other types of hepatic diseases in order of frequency was as follows: fulminant hepatitis (18.18%), CAH without cirrhosis (15.13%), subacute severe hepatitis (13.43%), CPH (5.88%), primary hepatocellular carcinoma (3.85%), and acute hepatitis (2.42%). Serological markers of HBV infection were detectable concomitantly in 77 of the 90 cases who were anti-HCV positive, but there was no evidence of mutual inhibition of viral replication. There was neither appreciable difference in the level of hyperbilirubinemia in cases of hepatitis with or without anti-HCV, nor significant diversity in the number of death between cases of severe hepatitis with and without anti-HCV.

Hepatitis E virus antigen (HEV Ag) has been identified in liver tissues of 6 out of 14 patients with type E hepatitis by direct immunoperoxidase staining, using anti-HEV-IgG-HRP. HEV Ag was found to be diffusive or inclusive in the cytoplasm of hepatocytes were scattered and isolated, but might aggregate in some parts where the liver damage was severe. We found that lymphocyte invaded the HEV Ag positive hepatocyte. These phenomena suggest that the liver damage is related to immunoreaction. HEV Ag was not found in the liver tissues of stillborn fetus and newborn baby from woman patients with hepatitis E. To detect HEV Ag in liver with direct immunoperoxidase method, using anti-HEV-IgG-HRP is more efficient than using anti-HEV-IgM-HRP.

Hepatocyte stimulator peptide (HSP) is a new hepatic stimulator substance. Its monoclonal antibodies have been obtained in our laboratory. In this study, HSP was determined in the sera of 315 subjects including patients with various forms of hepatitis and healthy persons with enzyme-linked immunosorbent assay (sandwich method). It is shown that HSP level in the sera of patients with fulminant hepatitis was high and correlated with the level of tumour necrosis factor (TNF), serum bilirubin (SB) or prothrombin time (PT). It is suggested that level of HSP in the sera of the patients reflected the degree of hepatocyte injury. A formula was recommended to predict the outcome of the patients with fulminant hepatitis.

There have been many reports on renal lesions of alcoholic cirrhosis, but not on those of post-hepatitis cirrhosis (PHC) up to present. A clinical and pathological observation on PHC was carried out prospectively in 18 and retrospectively in 34 cases. Renal specimens were examined with light and electron microscopy and immunopathological methods (immunofluorescence and peroxidase anti-peroxidase). Clinically, recurrent gross hematuria was observed in 2 and wild urinary abnormality in 17 cases. One case developed renal failure and the remaining 32 cases had no clinical evidence of renal involvement. Light microscopy showed wild mesangial lesions in 44 cases and glomerular basement membrane (GBM) thickening with segmental splitting in 29 and diffuse splitting in 2 cases. Massive protein deposition was found in the GBM, mesangium (Ms) and tubular basement membrane as well as the epithelium and endothelium. Immunopathological examination showed massive deposition of various immunoglobulins and complements in GBM and Ms, with IgG dominant in 8, IgM dominant in 7, IgA dominant in 6 and "full house" in 11 cases. HBsAg was detectable in GBM and Ms in 5 cases (9.6%) and HBcAg in one. Focal interstitial fibrosis and lymphocytic infiltration were found in 15 (28.3%). Our data revealed that renal lesions of post-hepatitis cirrhosis are different from those of the so-called "cirrhotic glomerulonephritis" in certain aspects. They are characterized by definite GBM involvement and massive deposition of immunoglobulins and complements. Its pathogenesis may be more complicated than that of other types of liver cirrhosis.

Between August and September 1987, 562 patients were hospitalized with acute non-A, non-B hepatitis. The male to female ratio was 1.4:1, and 75% of the patients was of 15-40 years of age. Jaundice developed in 87%. The overall case-fatality rate was 1.4%, but it was highest among pregnant women (5.2%) and newborn infants (24.2%). In general, the disease was self-limited with no evidence of chronic infection. Liver biopsies obtained during the acute illness showed portal inflammation and cytoplasmic cholestasis. Of 31 specimens of stool examined with a prototype ELISA for HEV antigen, 8 were found to be 'positive' and confirmed with immune electron microscopy (IEM). IEM examination of 'patients' stool revealed 27-32 nm viruslike particles. Inoculation of rhesus monkeys with patients stool containing virus-like particles produced acute hepatitis and the acute phase serum reacted with these particles in IEM, while preinoculation serum specimens were non-reactive.

77 patients with chronic active or persistent hepatitis of type B proved by liver biopsy were divided into two groups. 39 cases were treated with Ara-A. dauricine and polysaccharide of pore umbellate as group I. 38 cases were treated with Ara-A, radix isatidis and radix salviae mitiorrhize as group II. By the end of 3 months in the course, the effective rates of ALT and AST were 68.6% and 68.4% in group I, 34.4% and 34.8% in group II. The rates of HBeAg from positive to negative were 35.9% and 39.5% in group I and II respectively. Follow up to 3 months after cessation of therapy, ALT level was normal in 55.6% of group I and 60% of group II: HBeAg was negative in 42.9% of group I and in 50% of group II. Follow up to 9 months after cessation of the treatment, ALT was normal in 56.3% of group I and in 62.5% of group II, HBeAg was negative in 37.5% of group I and in 60% of group II. These results show that dauricine and polysaccharide of pore umbellate did not strengthen the antiviral effect of Ara-A.

In this study, HBsAg, HBcAg and HBV DNA in myeloid cells of 57 patients with hepatitis have been examined by using ABC staining method. The results show that in the myeloid cells of 54 patients with positive HBVM in serum, there are 4 cases with HBV positive antigen, HBcAg has been found in a case of acute hepatitis and HBsAg in a case of chronic hepatitis and a case of liver cirrhosis respectively, HBsAg and HBcAg were found simultaneously in another case of liver cirrhosis. Nothing has been found the myeloid cells of 3 cases with negative HBVM in serum. All these findings suggest that myeloid cells are probably another breeding ground for duplicating HBV.

The results of histological and immunohistological studies on the liver biopsies from patients with positive serum HBsAg, HBeAg, HBVDNA, and HBVDNAp showed: 1. In addition to the inclusion body like, marginal, diffuse and membranous patterns of HBsAg, we found that marginal and diffuse patterns of HBsAg may appear within one hepatocyte and this is named as transitional pattern. A preliminary suggestion about the process of formation and evolution of different patterns of HBsAg and HBcAg was raised. 2. There is a relationship between HBV replication and the activity of hepatitis. Different patterns and distributions of HBAg affect the lesion of the liver significantly. 3. According to the morphology of HBsAg and HBcAg, we suggest to divide their patterns into the following two categories: The first includes the diffuse and membranous patterns of HBsAg and the cytoplasmic and membranous HBcAg; these are related to the replication of HBVDNA. The second includes inclusion body like and marginal patterns of HBsAg with and without nuclear pattern of HBcAg; these probably reflect the integration of HBVDNA to the host genome.

Beta 2-Microglobulin expression on hepatocyte membrane was studied in 117 liver biopsies from patients with acute and chronic hepatitis B and in 11 subjects with normal liver function, using immunohistochemical PAP method. In normal liver beta 2-microglobulin could not be detected on hepatocyte membrane, compared with that in subjects with normal liver, in asymptomatic HBsAg carrier and in patients with chronic persistent hepatitis, there is significant enhancement of beta 2-microglobulin expression in patients with acute mild hepatitis and chronic mild active hepatitis. Beta 2-Microglobulin expression in patients with chronic active hepatitis with moderate to severe activity and cirrhosis has a significant enhancement, when compared with acute mild hepatitis and chronic mild active hepatitis. Moreover, location of beta 2-microglobulin expression on hepatocyte membrane was associated with lesion of hepatocytes. Enhanced expression of beta 2-microglobulin on hepatocyte membrane in acute and chronic hepatitis B probably reflects enhanced display of HLA-ABC antigens and may influence the course of hepatitis B virus infection by increasing susceptibility of T cell-mediated hepatocytelysis.

To clarify the correlation of hepatitis D virus (HDV) infection and viral replication in liver diseases, the authors detected HDV RNA and serological HDV markers in serum from 285 patients with hepatitis B and 45 asymptomatic carriers of HBsAg. With dot blot hybridization, serum HDV RNA was detected in 8.8% (29/330) of the patients with HBV infection. The positive rate of HDV RNA in fulminant hepatitis was higher than that in benign hepatitis (15/74 vs 3/47, P less than 0.05). 10 of the 139 patients with chronic active hepatitis and 1 of the 6 cases with cirrhosis were positive for HDV RNA. However, all of the 19 cases with chronic persistent hepatitis and 45 asymptomatic carriers of HBsAg were negative fo, HDV RNA. Serological HDV markers, HDAgr anti-HD and IgM-anti-HD, were determined with ELISA. HDV RNA was detected in all of the serum samples with positive HDAg and/or IgM-anti-HD, in 15 of the 26 cases with positive-anti-HD and in 8 cases without HDV markers. Our results showed that 40 of the 330 patients with HBsAg were infected by HDV. This investigation suggests that HDV is one of the etiological factors for fulminant hepatitis and chronic active hepatitis.
