Problems solved by technology

[0007] The patent (CN201910178248.X) discloses a preparation method of human umbilical cord mesenchymal stem cell injection for lacunar injection in the treatment of ischemic femoral head necrosis. The cartilage differentiation inducer of the injection includes glucose isoflavone, bone Formation protein-2, ascorbic acid, dexamethasone, and sodium β-glycerophosphate, these inducers cannot fix mesenchymal stem cells and cannot provide a regenerative microenvironment, and stem cells are easily lost in the body
The patent (CN201010152461.2) discloses a cell injection for treating bone damage and its preparation method. The gel is mainly poloxamer gel, which belongs to high molecular polymer and is not conducive to renal excretion.
[0008] At present, there are no relevant reports on the composite regenerative materials of acellular matrix fluid, bone marrow mesenchymal stem cells and angelica parasitic fluid to construct a tissue repair microenvironment for the repair of femoral head necrosis tissue

Abstract

The invention discloses a compound acellular matrix injection. The compound acellular matrix injection is taken as a femur head necrosis repairing material for clinical treatment. The compound acellular matrix injection is compounded by biological acellular matrix sol, bone marrow mesenchyml stem cells and radix angelicae sinensis parasitic liquids and is injected into a hip joint position betweenthe head of femur and the acetabulum in a surgery, a micro-environment for tissue repairing can be provided, the bone marrow mesenchyml stem cell is accelerated to carry out proliferation and differentiation to obtain osteoblasts, new vessels and new bones are induced to be formed, and the compound acellular matrix injection also has a function of diminishing inflammation and alleviating pain andcan be used for treating early and medium stage non-traumatic femur head necrosis.

Description

technical field [0001] The invention relates to a preparation method of a composite acellular matrix injection and its therapeutic application in femoral head necrosis, belonging to the field of medical biomaterials and tissue engineering repair. Background technique [0002] The pathogenic factors of non-traumatic femoral head necrosis are mainly divided into two types: chronic alcoholism and abuse of hormone drugs. Alcohol and hormones hinder the blood circulation around the femoral head, causing insufficient blood supply, resulting in necrosis of the femoral head, fracture of trabeculae, collapse of the femoral head, and paralysis of the patient in severe cases. Femoral head necrosis is divided into four stages: , The period is the early stage of subsidence; The period is the period of femoral head collapse, In the early stage, the femoral head collapses and develops into arthritis, which can be treated in the early and middle stages, and artificial hip replacemen...
