When acute hepatitis progresses to fulminant hepatitis, a large amount of hepatic cells are rapidly broken, and as a result, the prognosis is seriously worsened. Thus, it is important to prognose the progress of acute hepatitis into fulminant hepatitis at an early stage and quickly start an appropriate treatment therefor. Although the prognosis of progress into fulminant hepatitis becomes possible owing to recent advances in test methods and diagnostic techniques, there has been no appropriate prophylactic / therapeutic agent for fulminant hepatitis. The present invention provides a therapeutic agent for acute hepatitis or a prophylactic / therapeutic agent for fulminant hepatitis with little side effect. The problem of the invention was solved by using a composition containing apolipoprotein A-II.

The invention relates to the technical field of medicines, in particular to a drug for preventing and controlling fulminant hepatitis. Research shows the expression of the liver tissue A20 can be regulated up greatly by the NOD1 receptor agonist; the A20 (also called TNFAIP3) refers to anti-inflammatory signaling molecule, and can achieve anti-apoptosis action by lowering NF-kB signal channel, soas to protect the liver cells. Besides, the NOD1 receptor agonist can decrease the serum ALT level and the liver tissue cl-caspase3 level of mice with fulminant hepatitis greatly, thereby reducing liver injury of the mice with fulminant hepatitis and decreasing apoptosis of the liver cells. The conclusion is the NOD1 receptor agonist can be applied to treating fulminant hepatitis.

Keratin 8 and 18 (K8 / K18) mutations are shown to be associated with a predisposition to liver or biliary tract disease, particularly noncryptogenic hepatobiliary disease. Unique K8 / K18 mutations are shown in patients with diseases including but without limitation to viral hepatitis, biliary atresia, alcoholic cirrhosis and other acute or chronic toxic liver injury, cryptogenic cirrhosis, acute fulminant hepatitis, autoimmune liver disease, cystic fibrosis, primary biliary cirrhosis, primary sclerosing cholangitis, diseases that are linked with cryptogenic cirrhosis, such as nonalcoholic steatohepatitis, and the like. Livers with keratin mutations had increased incidence of cytoplasmic filamentous deposits. Therefore, K8 / K18 are susceptibility genes for developing cryptogenic and noncryptogenic forms of liver disease. Mutant alleles are associated with disease susceptibility, and their detection is used in the diagnosis of a predisposition to these conditions.

The invention discloses a method for constructing a RNA interference vector capable of simultaneously silencing multiple ligands of NKG2D, and application of the RNA interference vector. The method constructs a single vector capable of encoding shRNAs of multiple ligand molecules (Rae1, Mult1 and H60) of NKG2D. The vector can be further constructed to produce an adenovirus vector encoding shRNAs of multiple ligands of NKG2D and having an infectious ability. The vector can silence different target genes at the same time, to achieve the purpose of disease treatment. The vector can be applied to lower liver local microenvironment, including lowering the expression levels of Rae1, Mult1 and H60 on the surfaces of liver parenchymal cells, and is significant in prevention and treatment of NKG2D-dependent fulminant hepatitis. The invention develops the multi-target RNA interference technique and has important practical significance in multi-target gene therapy.

The invention relates to the technical field of medicine, in particular to a medicine for preventing and treating fulminant hepatitis. The research of the present invention shows that the NOD1 receptor agonist can significantly up-regulate the expression of A20 in the liver tissue. A20 (also known as TNFAIP3) is an anti-inflammatory signaling molecule. A20 can achieve anti-apoptotic effect by down-regulating the NF-κB signaling pathway, thereby protecting liver cells. Moreover, the NOD1 receptor agonist can also significantly reduce the serum ALT level and liver tissue cl-caspase3 level in mice with fulminant hepatitis, alleviate liver injury and hepatic cell apoptosis in mice with fulminant hepatitis. Therefore, NOD1 receptor agonists are considered to be useful in the treatment of fulminant liver injury.
