Embodiment 1

[0026] The preparation of embodiment 1 composite bioactive factor nano liposome

[0027]

[0028]

[0029] The preparation of the complex bioactive factor nanoliposome described in group A of the present invention comprises the following steps:

[0030] (1) Weigh 0.2g of phosphatidylcholine, 0.08g of cholesterol, and 0.04g of distearoylphosphatidylethanolamine, mix them, dissolve in 50mL of ethanol, and sonicate for 5min;

[0031] (2) Rotate evaporation at 28°C and 0.1MPa to remove ethanol, let it stand for 30min, add 100mL pH of 7.4 phosphate buffer solution containing 0.5% (m / v) complex biologically active factors, and place in a water bath at 35°C Medium shaking hydration reaction for about 1 hour to obtain liposome suspension;

[0032] (3) Use a syringe filter to adjust the particle size of the liposome suspension to 150nm to obtain nanoliposomes of complex bioactive factors.

[0033] For the preparation of complex biologically active factor nanoliposomes in groups...

Abstract

The invention relates to a scar removing composition, which comprises the following components in percentage by weight: 2 to 8% of hexa-peptide, 2 to 8% of five mineral peptide, 1 to 4% of thioctic acid, 0.05 to 1% of plumbagin, 1 to 4% of inositol, 2 to 6% of composite nano liposome with biological activity, and 70 to 80% of antiseptic with m / v of 0.01-1.0% and auxiliary materials. The provided scar removing composition can prominently enhance the activity of matrix metalloproteinase, the degradation of accumulated I type collagen is promoted; the expression of fibronectin is obviously reduced; the density of fibroblast is reduced, the generation of scars is decelerated, the proliferative index of scar is decreased; the scar removing effect is good, at the same time, the clinical data shows that the scar removing composition also has a good effect for patients of hyper-plastic scars, and the cure rate can reach 96.7%.

Description

technical field [0001] The invention relates to the technical field of scar repair, in particular to a scar removing composition and a preparation method thereof. Background technique [0002] Scar is a hyperplastic lesion caused by trauma. Its tissue is formed by collagen fibers and matrix, fibroblasts and local mucopolysaccharide deposition. The formation process includes different stages such as inflammation, cell migration / proliferation and deposition of extracellular matrix. The clinical manifestations are damaged skin shape and different degrees of dysfunction. According to the different causes and symptoms of scar formation, it can be divided into superficial scars, hypertrophic scars, atrophic scars, contracture scars, depressed scars, painful scars, and keloids. At present, the mechanism of scar formation is not yet fully understood. It is generally believed that the massive proliferation and apoptosis of fibroblasts in wound repair, the unbalanced synthesis and de...
