Background: Viral hepatitis, particularly hepatitis B (HBV) and hepatitis C (HCV), is highly prevalent in Mongolia. Moreover, Mongolia has the highest prevalence of hepatitis delta virus (HDV) globally, with over 60% of HBV-infected individuals also co-infected with HDV. Since HBV/HDV infections accelerate liver disease progression more compared to HBV infection alone, urgent national health measures are required. Method: This study presents a clinicopathological analysis of 49 hepatocellular carcinoma cases surgically resected at the Mongolia-Japan Hospital of the Mongolian National University of Medical Sciences. Results: HBV infection was found in 27 (55.1%) cases of all HCC cases. Immunohistochemical staining of the liver revealed that 14 (28.6%) cases were HDV antigen-positive in the HCC cases. HDV-positive cases exhibited significantly higher inflammatory activity compared to HDV-negative cases, with lymphocytic infiltrates predominantly composed of CD4-positive cells. Furthermore, HDV-positive cells were spatially distinct from HBs antigen-positive cells, suggesting that HDV-infected cells may interfere with HBV replication. No significant differences in fibrosis or in tumor characteristics were observed between the HDV-positive and negative cases. Early diagnosis of HBV/HDV infections is essential for appropriate treatment and to prevent further domestic transmission of the virus. However, routine testing for HDV infection is rarely conducted in Mongolia. Since HDV-positive cells are morphologically indistinguishable from surrounding HDV-negative cells, routine histopathological analysis may not be sufficient enough to detect HDV infection. Conclusions: Based on this clinicopathological study, CD4 and CD8 immunostaining can be considered an adjunctive diagnostic tool in cases with significant lymphocytic infiltration and hepatocellular damage. Additionally, HDV screening using blood and tissue samples may be recommended to ensure accurate diagnosis.

Herbal products are considered important medicinal sources in both traditional medicine and modern pharmacology. Our study examined the lung-protective and anti-inflammatory properties of the herbal formulation in alipopolysaccharide (LPS)induced model of acute lung injury. Non-cytotoxic concentrations in cells were evaluated in vitrousing the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay and analysis of nitric oxide (NO) production. In our invivo study, acute lung inflammation was induced in experimental animals by LPS. Treatment with the herbal formulation notably decreased NO production, increased superoxide dismutase (SOD) levels, and reduced the protein levels of tumor necrosis factor-alpha (TNF-α) and high-mobility group box 1 (HMGB1). Furthermore, histopathological studies confirmed its protective effects against LPS-induced lung inflammation. Molecular docking revealed that glycyrrhizic acid and inulin interact strongly with TNF-α and HMGB1 proteins, supporting their potential to mediate the observed anti-inflammatory effects.In conclusion, the herbal formulation demonstrates anti-inflammatory and lung-protective properties, suggesting its potential efficacy in mitigating LPS-induced acute lung injury.
