BACKGROUND. HCV-infected and obesity related liver diseases are leading to increases in the prevalence of advanced liver disease. So, studying liver disease, especially liver fibrosis is crucial issue of today. In Mongolia digestive system disease is second causation of non-communicable disease. Therefrom in last years hepatocellular carcinoma is most common malignancy, first of all cancers in Mongolia. In response to acute or chronic liver injury, hepatic fibrosis is the accumulation of extracellular matrix and ultimately leads to cirrhosis. Cirrhosis is the end-stage of fibrosis, resulting in nodule formation that may lead to altered hepatic function and blood flow. Defining the phase of liver fibrosis is crucial for therapeutic choice prognosis, important role in monitoring treatment. At the present time, use of direct and undirect biomarkers methods could be recommended for liver fibrosis stage. The aim of this study is to determine liver fibrosis stage and to compare undirect biomarkers in chronic viral hepatitis, cirrhosis. METHODS: 630 cases by chronic viral hepatitis and cirrhosis at third central hospital in Mongolia from retrospectively reviewed and analysed. The clinical data including AST, ALT, platelet count and INR were recorded. APRI, FIB-4, AAR and FibroQ were calculated. RESULT: From all, males 42.06% and females 57.94%, with mean age of 55.35±24.0, in 130 cases with chronic viral hepatitis and 500 cases with cirrhosis. In cases of cirrhosis, mean value of platelet count, ALT, AST, INR was 120.54±73.53, 104.55±500.22, 111.68±279.97, 2.19±10.45, respectively. And in cases of chronic viral hepatitis platelet count mean value was 211.18±6.42. APRI was detected <0.5 cutoff value (F0-F1) 11.7% non-fibrosis, 0.5-1.5 score (F2-F3) 27.5% fibrosis, >1.5 cutoff value (F4) 60.8% cirrhosis. FIB-4 was determined <1.45 cutoff value (F0-F1) 14.8% non-fibrosis, 1.45-3.25 score (F2-F3) 15.7% fibrosis, >3.25 cutoff value (F4) 69.5%, AAR was showed <0.4 cutoff value (F0-F1) 2.3% non-fibrosis, 0.4-1 score (F2-F3) 30.2% fibrosis, >1 cutoff value (F4) 67.5%. And FibroQ was detected <0.6 cutoff value (F0- F1) 0.5% non-fibrosis, 0.6-2.6 score (F2-F3) 6% fibrosis, cutoff value 2.6< (F4) 93.5 cirrhosis. In study liver fibrosis staging by APRI, AAR, FIB-4 and FibroQ score system, AAR was determined fibrosis in 190 cases. CONCLUSION: Recorded data ALT, AST, INR in cases of cirrhosis were detected 104.55±500.22, 111.68±279.97, 2.19±10.45, respectively. And in cases of chronic hepatitis platelet count mean value was 211.18±6.42. APRI, AAR, FIB-4, FibroQ was determined fibrosis 27.5%,30.16%,15.71% and 6.03%, respectively.

Background: There are 13283 people per 100 000 were diagnosed with skin cancer in 2016. Skin cancer is reported not widely in Mongolia. However, melanoma and non-melanoma new case are gradually increasing since 2010. Rhubarb is an old and well-known traditional Mongolian herbal medicine. Rhubarb is rich of bioactive compounds and widely distributed around Mongolia. People are still using Rhubarb as in food consumption and traditional medical treatments. Yet, there is not reported any therapeutic effect of rhubarb based on scientific research.PurposeTo investigate the anti-cancer activities of rhubarb (Rheum undulatum.L), a new herbal preparation from Mongolia, on B16F10 cells Material and Methods: The shoot of rhubarb was soaked with 40% ethanol and methanol. Murine melanoma B16F10 and RAW264.7 macrophage cell lines were purchased from the American Type Culture Collection (ATCC). Cell viability was determined CCK-8 assay. The antimigratory effect of Rhubarb (50-400 μg/μl) was investigated by a wound healing assay for 12 hours. Apoptosis was then evaluated by Western blot analysis. All experiments conducted at Core laboratory of Mongolian national university of medical sciences and Genomics laboratory of Mongolian university of life sciences from November 2015 to February 2017. Results: Ethanol and methanol extract of rhubarb inhibited the proliferation of B16F10 and RAW264.7 cells. In WHMA, cell migration was gradually decreased by concentrate dependent groups compare to the control group. Furthermore, protein expression PARP, Akt, BCL2, BAX and mTOR was investigated. BAX, Akt were down-regulated by rhubarb extraction as expected. DNA fragmentation assay have shown a dose dependent increase in the fragmentation of the DNA signifying apoptotic changes in the R.u extract treated B16F10 cells. Conclusion Rhubarb (Rheum undulatum.L) shows promising anti-cancer activity and can be useful in therapeutic treatment of skin cancer.
