The invention discloses an establishment method and application of a type-1 autoimmune hepatitis mouse model, and relates to the technical field of biology, and the technical key points are as follows: an adenovirus is combined with an overexpression Sepsecs plasmid to realize continuous expression of autoantigen in the liver, a chronic liver inflammation model conforming to type-1 AIH characteristics is successfully induced in a mouse body for the first time, and the mouse model has a good application prospect. The model shows clinical pathological characteristics of continuous infiltration of inflammatory cells, abnormal liver function, autoantibody generation, hepatic tissue fibrosis and the like, and has good stability and repeatability. At present, no type 1 AIH mouse model constructed by using the Sepsecs antigen is publically reported at home and abroad, and the technical blank in the field of type 1 AIH chronic animal models is filled. The model can be used for AIH pathogenesis research, autoantigen screening, novel diagnostic marker discovery, immune intervention means evaluation and clinical verification before new medicine, has wide scientific research and industrial application prospects, and provides an ideal experimental animal model platform.

The present application relates to the field of biological medicine and functional food, and discloses a kind of nutrition composition based on marine shrimp peptide for anti-obesity and improving metabolic syndrome;Including: Chinese tube whip shrimp peptide active component and pharmaceutically acceptable adjuvant, the Chinese tube whip shrimp meat protein is used as raw material, and the Chinese tube whip shrimp meat protein is prepared by alkaline protease enzymolysis, and the Chinese tube whip shrimp meat protein contains peptide segment with molecular weight less than 1 kDa, and APPPPP, HPPPP and MPLPP can be detected.The pharmaceutical composition can reduce the weight and fat tissue weight under the state of obesity, improve dyslipidemia, abnormal liver function and liver steatosis, reduce oxidative stress level, improve intestinal mucosal barrier damage and intestinal permeability increase, and regulate intestinal flora structure change.The active component in the present application is clear in origin, and the preparation process is clear, has the synergistic effect from lipid metabolism regulation, liver protection to intestinal barrier improvement, and can be used for preparing medicine for preventing or treating obesity and improving metabolic syndrome.

The present application relates to the application of mitochondrial transplantation preparation in the preparation of a drug for treating non-alcoholic fatty liver disease, wherein the mitochondrial transplantation preparation comprises active mitochondria isolated from healthy donor cells, and has normal membrane potential and mitochondrial respiratory function. In vivo experiments on a non-alcoholic fatty liver mouse model prove that tail vein injection of the mitochondrial transplantation preparation of the present application can effectively reduce the weight of the mouse, improve the fatty liver condition of the mouse, reduce the accumulation of fat in the liver tissue, and at the same time restore the abnormal liver function of the non-alcoholic fatty liver mouse.

The invention belongs to the technical field of food fermentation, and discloses an anti-aging, anti-oxidation and blood fat-reducing enzyme liquid and a preparation method thereof. The enzyme liquid is prepared by taking 2-5 parts of hawthorn, 2-5 parts of apple, 1-3 parts of lemon, 0.8-1.5 parts of ginkgo and 1.5-2.5 parts of broken rock sugar as main raw materials, supplementing mountain spring water and honey, and performing raw material pretreatment, primary constant-temperature fermentation and secondary constant-temperature fermentation. The ginkgo seeds are boiled to remove toxins, the primary fermentation is carried out at 28-35 DEG C for 60-90 days, and the secondary fermentation is carried out at 25-32 DEG C for 25-35 days. The prepared enzyme liquid is yellowish, transparent and bright and fragrant in smell, has the remarkable effects of resisting oxidation and aging and assisting in reducing blood fat, can improve intestinal flora and whiten skin, and is suitable for auxiliary conditioning of hyperlipidemia, nephritis and abnormal liver function. The invention has the advantages of scientific formula, controllable process, high safety and good stability, and is suitable for industrial production and market promotion.

The invention provides a Tibetan medicine composition for lowering lipid and protecting liver. The Tibetan medicine composition is prepared from the following components in parts by weight: 9-16 parts of fried dracocephalum tanguticum, 6-10 parts of fructus cassiae fistulae and 3-8 parts of calyx. The invention also provides a preparation method and application thereof. Compared with the prior art, the Tibetan medicine composition has the advantages that three Tibetan medicines with the effect of clearing liver heat are screened according to the symptom relation between liver heat and liver diseases and in combination with the basis of early-stage research and are subjected to formula compatibility, the Tibetan medicine composition for lowering lipid and protecting liver is further provided, and by multi-angle research on the preparation process and pharmacodynamics of the Tibetan medicine composition, the effect of lowering lipid and protecting liver is achieved. It is verified that the composition can significantly adjust abnormal liver functions and blood lipid indexes in serum of metabolism-related fatty liver model rats and improve pathological changes such as fatty degeneration and inflammation of liver tissue.

The invention provides an auxiliary prediction method and device for liver failure after liver resection, electronic equipment and a storage medium, and the method comprises the steps: obtaining clinical baseline data, iconography data, preoperative laboratory indexes, operation plan information and postoperative liver failure results of a plurality of groups of sample patients subjected to liver partial resection operations, and based on a plurality of groups of training data, carrying out the liver partial resection operations on the basis of the clinical baseline data, the iconography data, the preoperative laboratory indexes and the operation plan information; training to obtain a liver failure prediction model; obtaining clinical baseline data, iconography data, preoperative laboratory indexes and operation plan information of the target patient; and inputting the clinical baseline data, the iconography data, the preoperative laboratory indexes and the operation plan information of the target patient into the hepatic failure prediction model to obtain the occurrence probability of the abnormal hepatic function indexes of the target patient after the hepatic resection. According to the technical scheme provided by the embodiment of the invention, the liver failure prediction model is trained through a large amount of different clinical data, the accuracy of liver failure prediction after the hepatic resection is improved, and early warning can be performed on high-risk patients in time.

The invention discloses a traditional Chinese medicine composition for treating fatty liver, diabetes mellitus and abnormal liver function, and belongs to the technical field of traditional Chinese medicine compositions. The traditional Chinese medicine composition is prepared from the following raw materials in parts by weight: 9 to 15 parts of herba artemisiae annuae, 3 to 6 parts of radix et rhizoma rhei, 9 to 12 parts of fructus gardeniae, 3 to 6 parts of tetrapanax papyriferus, 12 to 18 parts of herba polygoni avicularis, 9 to 15 parts of herba dianthi, 12 to 18 parts of rhizoma dioscoreae colletii, 15 to 21 parts of talc and 3 to 6 parts of radix glycyrrhizae. The traditional Chinese medicine composition can solve the problem of abnormal liver function caused by phlegm-damp-heat stasis-turbid stagnation, and component toxicity is reduced due to a simple prescription; the traditional Chinese medicine is mainly used for dredging liver and gallbladder stasis heat, and can eliminate phlegm damp-heat stasis turbidity from intestinal tracts and urethra, so that a good treatment effect on liver dysfunction is realized.
