This invention discloses a virulent strain of type I canine adenovirus and its application in constructing animal infection models, belonging to the field of biotechnology. The virulent strain of type I canine adenovirus is named canine adenovirus type 1 strain 0601, with accession number CCTCC NO: V202604. The virus titer reaches 10. 7.5 TCID 50 / mL. This virus can be used to construct an animal model of canine adenovirus type I infection, which exhibits typical clinical symptoms, such as hepatic hemorrhage, hepatocellular necrosis, and venous and sinusoidal congestion. The constructed animal model can be used for future canine adenovirus vaccine development, immune protection assessment, and efficacy evaluation of preventive and therapeutic drugs, providing excellent biological materials and theoretical basis for further control of canine adenovirus type I.

The present invention provides, in part, novel small molecule inhibitors of PHD, having a structure according to Formula (I), and sub-formulas thereof: Formula (I) or a pharmaceutically acceptable salt thereof. The compounds provided herein can be useful for treatment or prevention of diseases including heart (e.g. ischemic heart disease, congestive heart failure, and valvular heart disease), lung (e.g., lung inflammation, pneumonia, acute lung injury, pulmonary hypertension, pulmonary fibrosis, and chronic obstructive pulmonary disease), respiratory (e.g.,respiratory infection, acute respiratory distress syndrome), liver (e.g. acute liver failure and liver fibrosis and cirrhosis), and kidney (e.g. acute kidney injury and chronic kidney disease) disease, inflammatory bowel disease (IBD), ischemic reperfusion injury (e.g., stroke), retinopathy of prematurity (ROP), bronchopulmonary dysplasia (BPD), and white matter injury (WMI).

This invention discloses a polyethylene glycol-modified magnesium boride nanosheet and its application in treating acute liver failure and hepatic encephalopathy caused by acetaminophen. The nanosheet uses magnesium boride nanosheets as a core, with polyethylene glycol modified on the surface to improve biocompatibility. The nanosheet of this invention exhibits good antioxidant properties and can be used to prepare nanomedicines for treating acute liver failure and / or hepatic encephalopathy caused by acetaminophen. It generates reducing hydrogen gas through a hydrolysis reaction, effectively scavenging reactive oxygen species at the site of liver failure, thereby inhibiting inflammatory responses and effectively alleviating symptoms caused by acute liver failure.

This invention relates to the field of biomedical materials technology, providing a heparinized dual-growth factor recellularized adipose tissue decellularized scaffold material, its preparation method, and its applications. The preparation method includes: decellularizing adipose tissue to obtain adipose tissue decellularized scaffold; heparinizing the scaffold to obtain a heparinized adipose tissue decellularized scaffold; loading hepatocyte growth factor and vascular endothelial cell growth factor onto the scaffold to obtain a heparinized dual-growth factor adipose tissue decellularized scaffold; seeding induced pluripotent stem cell-derived hepatocytes onto the scaffold, and culturing to obtain a heparinized dual-growth factor recellularized adipose tissue decellularized scaffold (RAT). This invention uses rat inguinal adipose tissue to prepare RAT material, which is low-cost, readily available, has a simple preparation process, and is easy to scale up. The RAT material of this invention can achieve liver tissue damage repair and hepatocyte regeneration, providing a new treatment strategy for acute liver failure.

This invention discloses the application of β-1,4-galactosyltransferase 1 and its inhibitors in liver diseases, particularly acute liver injury and liver failure. The application of β-1,4-galactosyltransferase 1 and its inhibitors in acute liver injury and liver failure provides the correlation between β-1,4-galactosyltransferase 1 and acute liver injury and liver failure, confirming that inhibiting the activity of β-1,4-galactosyltransferase 1 can alleviate acute liver injury and liver failure. β-1,4-galactosyltransferase 1 can serve as a drug target for screening acute and chronic hepatitis, liver injury, fatty liver, liver fibrosis, and acute and chronic liver failure. This invention also confirms the alleviating effect of β-1,4-galactosyltransferase 1 inhibitors on acute liver failure. β-1,4-galactosyltransferase 1 inhibitors improve acute liver failure by reducing the enzyme activity or protein expression of β-1,4-galactosyltransferase 1.

The present invention provides, in part, novel small molecule inhibitors of PHD, having a structure according to Formula (I), and sub-formulas thereof:or a pharmaceutically acceptable salt thereof.  The compounds provided herein can be useful for treatment or prevention of diseases including heart (e.g. ischemic heart disease, congestive heart failure, and valvular heart disease), lung (e.g., lung inflammation, pneumonia, acute lung injury, pulmonary hypertension, pulmonary fibrosis, and chronic obstructive pulmonary disease), respiratory (e.g., respiratory infection, acute respiratory distress syndrome), liver (e.g. acute liver failure and liver fibrosis and cirrhosis), and kidney (e.g. acute kidney injury and chronic kidney disease) disease, inflammatory bowel disease (IBD), ischemic reperfusion injury (e.g., stroke), retinopathy of prematurity (ROP), bronchopulmonary dysplasia (BPD), and white matter injury (WMI). 

The present application relates to the field of medical artificial intelligence and clinical auxiliary decision-making technology, in particular to an abnormal test result combination pattern recognition method and system based on deep learning, comprising: receiving test results output by a hospital test information system to construct a 48-dimensional test index vector; calculating a multi-dimensional joint deviation degree based on a group health joint distribution reference model; constructing a patient individual baseline with stable period test values for baseline drift correction, and inferring an individual baseline and giving a baseline disturbance double-channel representation when the stable period is missing with a meta-learning baseline inference subnetwork output; inputting the individualized joint deviation degree and the baseline disturbance double-channel representation into a multilayer perceptron network classifier to output five types of severe clinical event prediction probabilities of sepsis, acute kidney injury, disseminated intravascular coagulation, acute liver failure and acute exacerbation of chronic diseases, and the training loss contains a pathogenic causal diagram prior constraint term; when the prediction probability exceeds 40%, an orange reminder is pushed to the mobile terminal of the responsible nurse.

This invention relates to a novel use of synephrine in the preparation of drugs for treating cholestatic liver disease, belonging to the field of pharmaceutical technology. Cholestatic liver disease is characterized by jaundice and conjugated bilirubin and / or total bilirubin hyperconjugation caused by impaired bilirubin excretion due to various reasons. Its causes include common bile duct stones, pancreatic duct cancer, common bile duct malignant tumors, pancreatic cancer, biliary parasitic diseases, viral hepatitis cirrhosis, alcoholic liver disease, fatty liver disease, drug-induced liver injury, primary biliary cirrhosis, intrahepatic sclerosing cholangitis, and certain congenital diseases such as Dubin-Johnson syndrome and Rotor syndrome. This invention establishes a mouse cholestasis model using bile duct ligation and administers synephrine by gavage to evaluate its protective effect against liver injury. The results showed that synephrine significantly improved jaundice caused by cholestasis, reduced hepatocellular necrosis and inflammatory infiltration caused by cholestasis, alleviated bile duct dilation, decreased serum total bilirubin (TBIL) and direct bilirubin (DBIL), and reduced the levels of total bile acids (BA) in liver tissue and plasma. Furthermore, the above-mentioned effects of synephrine in improving cholestasis showed a clear dose-dependent effect. This invention reveals for the first time the application of synephrine in cholestatic liver disease, demonstrating good safety and promising clinical development prospects.
