Description
Technical field
The invention belongs to biomedical material technologies.More particularly, to a kind of aquagel and its preparation
Method.
Background technique
Scar is dermis of skin fibroblast proliferation disorder, and fibroblast is caused excessively to generate, collagen over-deposit
It is formed, common complication, drastically influences the appearance and psychology of patient after being skin trauma and performing the operation.The morbidity machine of scar
System and its control method are always the research hotspot of medical field, there is no specific conclusion to the research of its pathogenesis at present.Scar
Trace is the product of skin ultrastructure and agglutination, any in addition to the shallow wound of table can be formed by simple epithelium and be repaired
Damage as deep as corium and subcutaneous tissue can all be repaired by cicatrization.Theoretically, scar once being formed, even if adopting
With most fine operation method, although it is made to obtain part improvement, and cannot thoroughly eradicate.
The treatment course of scar is longer, and clinical treatment method is more at present, and excision of such as performing the operation, pressure therapy, radiation are controlled
Treatment, laser therapy, optical dynamic therapy etc., but effect is also not satisfactory, and scar is easy to recur.There are also for treating for Vehicles Collected from Market
The drug of scar, such as hormone medicine, anti-tumor drug, Arg-Pro-Lys-Pro-Gln-Gln-Phe-Phe-Gly-Leu-Met-NH2 inhibitor, cell factor, immunosuppressor.But these
Drug price is expensive, and manufacturing process is cumbersome, and effect is different, and there are a degree of adverse reactions.
The cardinal principle of scar treatment is removal lesion, and passes through the conjunction of the fibroblastic proliferation of inhibition and its collagen
At, secretion or deposits and prevent its recurrence.Breviscapinun（Breviscapine）It is from compositae plant Erigeron breviscapus（Erigeron
breviscapus（Vant.）Hand. -Mazz.）Drying herb（Also known as erigeron breviscapus）The flavonoids of middle extraction effectively at
Point, there is anticoagulation, antithrombus formation and promote a series of pharmacological actions such as fibrinolytic, anti-inflammatory, anti-oxidant, Antipyretic.
Some researches show that Breviscapinun can inhibit fibroblastic hyper-proliferative in Process of Forming Scar, have one to cicatrization
Surely the effect inhibited.But Breviscapinun antibacterial effect is bad.
Chitosan is natural marine high molecular material, has good biocompatibility, degradable, non-immunogenicity, nontoxic pair
The potential advantages such as effect, abundance, at the same also have the function of well stop blooding, antibacterial and promote wound healing, hemostasis and
There is good application in wound repair, wound healing can be accelerated.But natural chitosan high molecular material stability is poor.
Summary of the invention
The technical problem to be solved by the present invention is to overcome the defect of the above-mentioned prior art and deficiencies, for wound, burn, scald
There are certain adverse reactions in skin trauma caused by the reasons such as wound, operation and the cicatrization therapeutic process after wound repair
And the problems such as recurrence rate, provide that a kind of toxic side effect is low, can effectively inhibit the aquagel of cicatrization.The Compound Water
Gel process for preparing is simple, and the hydrogel being prepared into can not only accelerate the healing of wound, and can efficiently inhibit scar
Formation, fibroblastic hyper-proliferative can be inhibited in wound healing process and can induce its occur apoptosis, from the root
Resist the generation of scar.
Another object of the present invention is to provide the preparation method of above-mentioned aquagel.
Another object of the present invention is to provide the aquagel and inhibits the application in cicatrization preparation in preparation.
Above-mentioned purpose of the present invention is achieved through the following technical solutions：

~0.8.
Preferably, the molecular weight of the chitosan is 10KDa~100KDa, deacetylation is 90%~92%, the oxidation
The molecular weight of graphene is 3000Da~8000Da.
Hydrogel provided by the invention passes through effective combination of Breviscapinun, chitosan and graphene oxide, can accelerate to create
The healing of face wound has the characteristics that hemostasis, antibacterial and inhibition cicatrization from the root, can shorten the clotting time, accelerate wound
Face healing and the formation for reducing scar.
The present invention protects the preparation method of above-mentioned aquagel simultaneously, includes the following steps：
S1. it dissolves chitosan in acetic acid solution, obtains chitosan acetic acid solution；Add graphene oxide into chitosan second
It is mixed in acid solution, obtains chitosan/oxidized graphene mixed solution；
S2. Breviscapinun powder is added in chitosan/oxidized graphene mixed solution, after being uniformly mixed, deaeration,
Obtain Breviscapinun/chitosan solution；
S3. be blended after additive being configured to corresponding additive aqueous solution, to be added dose of aqueous solution after mixing, by it
It is blended with Breviscapinun/chitosan solution of S2, controlling additive aqueous solution with Breviscapinun/chitosan solution mass ratio is
2:1~4:1, then proceed to heating, stir to solution it is transparent after, stop heating, stirring, go bubble removing to get chitosan water-setting
Glue.
Preferably, the mass fraction of chitosan is 2%~5% in chitosan acetic acid solution described in S1.
Preferably, the mass fraction of Breviscapinun is 1%~3% in Breviscapinun/chitosan solution described in S2.
Compared with prior art, the invention has the advantages that：
