METHODS： All HCC patients attending Cairo Liver Center between January 1993 and December 2002, were enrolled in the study. Diagnosis of HCC was based on histopathological examination and/or detection of hepatic focal lesions by two imaging techniques plus α-fetoprotein level above 200 ng/mL. The duration of the study was divided into two periods of 5 years each; period Ⅰ （1993-1997） and period Ⅱ （1998-2002）. Trend, demographic features of patients （age, gender, and residence）, risk factors （HBsAg, HCV-Ab, schistosomiasis and others） and pattern of the focal lesions were compared between the two periods. Logistic regression model was fitted to calculate the adjusted odds ratios for the potential risk factors. The population attributable risk percentage was calculated to estimate the proportion of HCC attributed to hepatitis B and C viral infections. RESULTS： Over a decade, 1 328 HCC patients out of 22 450 chronic liver disease （CLD） patients were diagnosed with an overall proportion of 5.9%. The annual proportion of HCC showed a significant rising trend from 4.0% in 1993 to 7.2% in 2002 （P = 0.000）. A significant increase in male proportion from 82.5% to 87.6% （P = 0.009）; M/F from 5：1 to 7：1 and a slight increase of the predominant age group （40-59 years） from 62.6% to 66.8% （P = 0.387）in periods Ⅰ and Ⅱ respectively, reflecting a shift to younger age group. In the bivariate analysis, HCC was significantly higher in rural residents, patients with history of schistosomiasis and/or blood transfusion. Yet, after adjustment, these variables did not have a significant risk for development of HCC. There was a significant decline of HBsAg from 38.6% to 20.5% （P = 0.000）, and a slight increase of HCV-Ab from 85.6% to 87.9% in periods I and II respectively. HBV conferred a higher risk to develop HCC more than HCV in period Ⅰ （OR 1.9 vsl.6） and period Ⅱ （OR 2.7 vs 2.0）, but the relative contribution of HBV for development of HCC declined in period Ⅱ compared to period Ⅰ （PAR% 4.2%, 21.32%）. At presentation, diagnostic α-fetoprotein level （≥200 ng/mL） was demonstrated in 15.6% vs28.9% and small HCC （≤3 cm） represented 14,9% vs 22,7% （P = 0,0002） in periods Ⅰ and Ⅱ respectively. CONCLUSION： Over a decade, there was neady a twofold increase of the proportion of HCC among CLD patients in Egypt with a significant decline of HBV and slight increase of HCV as risk factors. α-Fetoprotein played a limited role in diagnosis of HCC, compared to imaging techniques. Increased detection of small lesions at presentation reflects increased awareness of the condition.展开更多

Twenty-four compounds including eight steroids （1-8）, nine triterpenoids （9-16, 24）, three flavonoids （20-22）, and four benzenecarboxylic derivatives （17-19, 23） were isolated and identified from stems and twi...Twenty-four compounds including eight steroids （1-8）, nine triterpenoids （9-16, 24）, three flavonoids （20-22）, and four benzenecarboxylic derivatives （17-19, 23） were isolated and identified from stems and twigs of medicinal mangrove plant Sonneratia caseolaris. The structures of the isolated compounds were determined by extensive analysis of their spectroscopic data. Among these rnetabolites, compounds 1, 4-20 and 22-24 were isolated and identified for the first time from S. caseolaris. In the in vitro cytotoxic assay against SMMC-7721 human hepatoma cells, compound 21 （3＇,4＇,5,7-tetrahydroxyflavone） exhibited significant activity with IC50 2.8 μg/mL, while oleanolic acid （14）, 3,3＇-di-O-methyl ether ellagic acid （18）, and 3,3＇,4-O-tri-O-methyl ether ellagic acid （19） showed weak activity. None of these compounds displayed significant antibacterial activites.展开更多

The method involves the preparation ofper-O-acetylated glycosyl isothiocyanates from per-O-acetylated sugars （two-step synthesis）, which couple with heterocyclic hydrazides from amines to give thiourea-linked pseudonucleosides. All newly synthesized pseudo-nucleosides were assayed against human lung cancer-cell lines （PG） and human liver cancer-cell lines （BEL-7402） in vitro. The 6,6-dimethyl-benzothiophen-3-carbo-hydrazide-4-one pseudonucleosides showed moderate inhibition against these two cancer-cell lines with ECs0 from 22.8 to 76.4 mM and from 54.9 to 82.4 mM, respectively. And the other compounds did not demonstrate any significant cytotoxicity even at concentrations up to 200 mM.展开更多
