Embodiment Construction

[0020] Below in conjunction with a preferred embodiment the present invention will be further described,

[0021] prescription:

[0022] Carbomer 940NF 10g

[0023] Sodium Hyaluronate 2.5g

[0024] Dextran 40 2.5g

[0025] Heparin sodium: bFGF 1:3

[0026] 4% sodium hydroxide 140ml

[0027] 4

[0028] Add water for injection to 1000ml

[0029] A total of 150 sticks

[0030] The specific preparation method is:

[0031] 1. Weigh 10.0g of Carbomer 940NF in a 1L beaker, add 250ml of water for injection to make it swell naturally, add 4% sodium hydroxide after swelling, stir while adding, adjust the pH to 7.0 (about 140ml), and obtain the maximum viscosity Consistency Base (I).

[0032] 2. Weigh 2.5g of sodium hyaluronate into a 500ml beaker, add 400ml of water for injection to make it swell naturally into a gel solution (II).

[0033] 3. Weigh 2.5g of dextran into a 500ml beaker, add 200ml of water for injection, heat to dissolve it into a dext...

Description

Technical field: [0001] The invention relates to a recombinant human basic fibroblast growth factor gel and a preparation method thereof. In particular, a recombinant human basic fibroblast growth factor gel suitable for treating burn wounds, fresh wounds and chronic wounds and a preparation method thereof. Background technique: [0002] Wound healing is a complex and highly coordinated process, which can be basically divided into three distinct and interlaced stages: local inflammatory response, cell proliferation and differentiation, and tissue repair and reconstruction. This process involves the interaction and mutual influence of various growth factors and cytokines, and jointly regulates cell migration, proliferation, differentiation, angiogenesis, matrix deposition and tissue modeling. [0003] In the traditional wound repair treatment, measures such as anti-infection, enhanced nutrition of the body and local protection of the wound are used to heal the wound naturall...
