The application provides a method for long-term in-vitro culture and expansion of primary hepatocytes and application thereof. The method for in-vitro culture and expansion of primary hepatocytes comprises using a culture medium containing interleukin-22 (IL-22), combined with hepatocyte growth factor (HGF) and / or epidermal growth factor (EGF) to induce primary hepatocytes to prepare proliferative liver precursor cells. The application combines interleukin-22 (IL-22), hepatocyte growth factor (HGF) and / or epidermal growth factor (EGF) to induce in-vitro mass expansion of primary hepatocytes, and through the method, mature-like hepatocytes with a gene expression profile extremely similar to that of primary hepatocytes and perfect functions can be obtained, and the hepatocytes expanded by the method have good in-vivo therapeutic effects.

The utility model relates to an unmanned aerial vehicle carrier loader for low-altitude emergency fire fighting, belongs to the technical field of fire extinguishing, and solves the technical problems that a water hose needs to be connected to an unmanned aerial vehicle on site in the prior art, time is consumed, and the fire extinguishing opportunity is delayed. The unmanned aerial vehicle comprises an unmanned aerial vehicle storage cabin, a water tank and a water hose assembly. The unmanned aerial vehicle storage cabin comprises a cabin body and a parking apron, and an unmanned aerial vehicle is parked on the parking apron; the water hose assembly comprises a water hose, one end of the water hose is connected to the unmanned aerial vehicle, and the other end of the water hose is connected to the water tank; when the parking apron does not ascend, the parking apron locks the water hose; after the parking apron ascends, the locking state of the water hose is released, and the water hose can be unfolded along with flying of the unmanned aerial vehicle. The water hose is connected with the unmanned aerial vehicle and the water tank, when the unmanned aerial vehicle flies out of the unmanned aerial vehicle carrier loader, the water hose is unfolded, the unmanned aerial vehicle directly enters a fire scene for fire rescue, the water hose connecting time is saved, and the fire behavior is controlled in time.

The invention provides a rapid microorganism drug sensitivity detection method, application and a product, and belongs to the technical field of microorganism drug sensitivity detection. The method comprises the following steps: S1, carrying out microbiological treatment to obtain a sample bacteria solution; s2, adding a to-be-detected medicine into the sample bacterial liquid, and incubating; s3, after incubation, enriching the thalli; and S4, adding a color developing agent to observe the color change. According to the method, drug sensitivity data can be obtained within several hours, the drug sensitivity detection speed is increased, and the method is suitable for drug sensitivity detection of pure cultures of bacteria and fungi and also suitable for drug sensitivity detection of blood culture positive samples, urine samples and other samples with high bacterium content. The method is of great significance in rapidly guiding clinicians to reasonably take medicines, reducing the death rate of infected patients and saving the lives of the patients.
