Early and accurate prognostic assessment of patients with ALF is critically important for optimum clinical pathway. DATA SOURCES: Five English-language medical databases, MEDLINE, Science Direct, OVID, Springer Link and Wiley Interscience were searched for articles on 'acute liver failure', 'prognosis', and related topics. RESULTS: Multi-variable prognostic models including the King's College Hospital criteria and the model for end-stage liver disease score have been widely used in determination of the prognosis of ALF, but the results are far from satisfactory. Other prognostic indicators including serum Gc-globulin, arterial blood lactate, serum phosphate, arterial blood ammonia, and serum alpha-fetoprotein are promising but await further assessement. CONCLUSIONS: A reliable prognostic model to be developed in the future should not only have predictive value for poor outcome but also help to predict the survival of patients without a liver transplantation. Further studies are necessary to assess the prognostic accuracy of any new models. (Hepatobiliary Pancreat Dis Int 2010; 9: 122-128)展开更多

Four flavonoids were isolated from the extract of F. sarmentosa var. henryi by activity-guided fractionation and they were identified as eriodictyol （1）, homoeriodictyol （2）, dihydroquercetin （3）, and luteolin （4） by spectroscopic means and displayed excellent inhibitory activity against F. graminearum and S. zeicola. Among them, luteolin （4） showed the strongest inhibitory activity with IC50 values of 56.38 and 81.48 mg L^-1, to the fungi, respectively. The in vitro inhibitory activity of F. sarmentosa var. henryi （King） Corner was reported for the first time and the inhibitory action mechanism of luteolin （4） was worthy of further research.展开更多
