[0029] Dressing is a medical product that protects wounds and promotes wound healing. Among them, dressings made of mussel mucin have high application prospects because of their molecular characteristics of being rich in dopa groups and carrying a large amount of positive charges, which can effectively promote wound healing, and have strong biocompatibility and low cytotoxicity.

[0030] However, because the dopa group in its molecule is very active, it is easy to be oxidized and cross-linked, thus losing its related functions, and the protein will precipitate from the solution due to oxidative cross-linking. Traditional irradiation sterilization methods will cause protein degradation or oxidative cross-linking precipitation. Therefore, there is an urgent need for a mussel mucin dressing that can be stably sterilized and stored at room temperature.

[0031] In this regard, the present application provides a method for preparing a recombinant mussel mucin cream dressing, comprising: obtaining a preset mass percentage of mussel mucin, an oily matrix, sodium hyaluronate, silk fibroin and a pH regulator; dissolving the mussel mucin in purified water and heating it to 80°C±5°C, adding a pH regulator to the mussel mucin to adjust the pH value to a preset range; adding sodium hyaluronate and silk fibroin to the mussel mucin and stirring them thoroughly to prepare a water phase; heating the oily matrix to 75-90°C to prepare an oil phase; adding the oil phase to the water phase, stirring the oil phase and the water phase by a stirring device until the oil phase and the water phase are evenly mixed to obtain a mussel mucin cream dressing.

[0032] Among them, the oil phase matrix is ​​generally heated to 75-90°C to ensure that the oil is completely melted.

[0033] In some embodiments, the mussel mucin can be a recombinant mussel mucin or a naturally extracted one. As an example, when using recombinant mussel mucin, the recombinant mussel mucin can be a genetically recombinant fp-151 type. The fp-151 type recombinant mussel mucin is a recombinant protein composed of 6 MAP1 type (fp-1) decapeptide repeat sequences at the C-terminus and N-terminus of the MAP5 type (fp-5). To prepare the recombinant mussel mucin, the mussel mucin freeze-dried sponge can be stirred in purified water until completely dissolved and heated to 80±5°C to obtain the recombinant mussel mucin.

[0034] The mussel mucin cream dressing prepared by the mussel mucin cream dressing preparation method provided in this embodiment is an oil-in-water system cream, which can solve the problem that the dopa group contained in mussel mucin is easily oxidized. The oil-in-water system can avoid the instability and stratification of the product after traditional wet heat sterilization. The oil-in-water system can effectively avoid the degradation of protein molecules during the storage period, and the product can be stored at room temperature. The storage conditions of the product are changed from special refrigerated or frozen storage to conventional room temperature storage, saving storage and transportation costs, and being more convenient to use.

[0035] In some embodiments, the preset mass percentages include: 3%-8% of mussel mucin; 5%-20% of oily matrix; 6%-16% of sodium hyaluronate; 1%-5% of silk fibroin, and the remainder is purified water.

[0036] In some embodiments, after obtaining the mussel mucin cream dressing, the method further includes: filling the mussel mucin cream dressing after it drops to a preset temperature, and sterilizing the filled mussel mucin cream dressing to obtain a sterile mussel mucin cream dressing.

[0037] Among them, the filled mussel mucin cream dressing can be sterilized by keeping the filled mussel mucin cream dressing above 121° C. for 9-30 minutes to achieve sterilization of the mussel mucin cream dressing.

[0038] Since the mussel mucin cream dressing provided in this embodiment utilizes the amphoteric properties of mussel mucin to adopt an oil-in-water system, the oil-water stratification phenomenon that is easy to occur in traditional cream dressings during high-temperature sterilization is avoided. After the product is sterilized by wet heat, the product maintains its original state, providing a new sterilization method for sterile cream dressings.

[0039] It should be noted that the mussel mucin cream prepared by the present invention is an oil-in-water system cream. The microscopic spherical droplets formed by the oil-in-water system reduce the contact between oxygen in the air and the recombinant mussel mucin to a certain extent, preventing oxidative cross-linking. On the other hand, the microscopic spherical droplets reduce the interaction force between mussel molecules and reduce the occurrence of oxidative cross-linking between molecules, thereby effectively preventing protein cross-linking and precipitation, and increasing the stability of the protein.

[0040] In some embodiments, the preset range of pH value includes: 3.0-4.2.

[0041] In some embodiments, the pH adjuster includes at least one of citric acid, boric acid, acetic acid, phosphoric acid, hydrochloric acid, triethanolamine, sodium hydroxide and potassium hydroxide.

[0042] In some embodiments, the oil phase and the water phase are stirred by a stirring device until the oil phase and the water phase are uniformly mixed, comprising: stirring the oil phase and the water phase by a stirring device at 1000-1500 r / min for 5-20 min.

[0043] In some embodiments, the oily base includes at least one of cetostearyl alcohol, glyceryl mono- and distearate, glyceryl stearate, beheneth-10, beheneth-25, and acrylates / C10-C30 alkyl acrylate crosspolymer.

[0044] The present application also provides a mussel mucin cream dressing, which can be prepared by a preparation method of the mussel mucin cream dressing.

[0045] In some embodiments, the mussel mucin cream dressing comprises: mussel mucin, an oily base, sodium hyaluronate, silk fibroin, and a pH adjuster.

[0046] In some embodiments, the mass percentage of mussel mucin is 3%-8%; the mass percentage of oily matrix is ​​5%-20%; the mass percentage of sodium hyaluronate is 6%-16%; the mass percentage of silk fibroin is 1%-5%; and the remainder is purified water.

[0047] The mussel mucin cream dressing in this embodiment includes mussel mucin, sodium hyaluronate and silk fibroin. The network structure formed by these three substances can play a good role in drug sustained release and provide a drug administration route for oil-soluble functional raw materials.

[0122] Figure 4 The electrophoresis diagram of the mussel mucin cream dressing prepared by the preparation method of the mussel mucin cream dressing provided in the present application is shown.

[0123] Take the mussel mucin cream dressing prepared in Example 1 as an example. The mussel mucin cream dressing was divided into 6 portions, one of which was not sterilized, and the other five portions were sterilized by moist heat, 5K irradiation, 10K irradiation, 15K irradiation and 20K irradiation, respectively. Then, an electrophoresis test was performed.

[0124] refer to Figure 4 ,Depend on Figure 4 It can be seen that the protein bands after moist heat sterilization are almost the same as before sterilization, indicating that the moist heat sterilized protein has not been significantly degraded. However, after different doses of irradiation sterilization, the protein is completely degraded and loses its function.
