Technical Field

The invention belongs to the technical field of biological medicines, and particularly relates to a composition for preventing and/or repairing skin damage and application thereof.

Background

With the improvement of the national economic level, people pay more and more attention to the health, and the repair caused by the damaged skin becomes a hot point of research. The hair follicle is the most important tissue involved in hair growth, and when skin damage occurs, such as burns, cold injuries, cutting injuries, the number of hair follicle formations in the healed tissue will ultimately determine the growth state of the new hair. Drugs currently available for therapeutic purposes, which are aimed at promoting hair follicle growth, inhibiting local inflammatory responses, and maintaining the structural and functional integrity of hair follicles, include anti-androgens, anti-inflammatories, free radical scavengers, and the like. However, due to the toxic and side effects of the chemical drugs and the limitation of drug resistance, the long-term administration treatment is not easy. Therefore, researchers pay more and more attention to medicines which have small toxic and side effects and strong specificity, promote the growth of hair follicles and repair damaged skin.

Puerarin is one of the most important active ingredients of kudzuvine root, has typical estrogen-like biological activity, and has obvious anti-inflammatory and antioxidant stress effects in vivo and in vitro, and the puerarin has been reported to effectively delay the aging state of skin (Zhengwei, kudzuvine root and experimental study on the influence of puerarin on the total antioxidant capacity and the hydroxyl radical inhibition rate of the skin of an aging mouse [ D ]. Liaoning traditional Chinese medicine university, 2012); the experimental research on the activity change of GSH-PX of the natural aging mice by inhibiting the oxidative stress state of the skin (plum-east, Wujing-east, Wangbei-Kudzuvine root and puerarin [ J ]. Chinese cosmetic medicine 2011,20(12): 1921-1922); meanwhile, the medicine also has obvious therapeutic effect on scar tissues (Yueyuemei, Yanshi ice, Maleyte. puerarin solutions with different concentrations have influence on the biological effect of human skin fibroblasts [ J ]. Tianjin traditional Chinese medicine, 2016,33(05): 311-. Regarding the combined use with puerarin, the prior art has reported that, for example, the combined use of puerarin and vancomycin hydrochloride can improve the wound healing effect, and the effect is superior to that of puerarin alone (Wangqiong. antibacterial hernia repair patch and research on wound repair [ D ]. Beijing synergetic medical college, 2013.). However, vancomycin hydrochloride is an antibiotic, and long-term use or abuse of the antibiotic is a major cause of drug resistance; nowadays, the importance of skin damage repair is increased, the use of skin damage repair medicines is increased, and the combined use of vancomycin hydrochloride and puerarin obviously has the risk of increasing drug resistance. Therefore, it is necessary to research the drug combining non-antibiotic and puerarin.

Adding the medicine into the blank gel to obtain a medicine-carrying gel: adding puerarin to make puerarin content be 1% to obtain puerarin gel; adding pericarpium Citri Tangerinae crude polysaccharide to make pericarpium Citri Tangerinae crude polysaccharide mass content be 0.5% to obtain pericarpium Citri Tangerinae polysaccharide gel; adding puerarin and crude polysaccharide of pericarpium Citri Tangerinae to make puerarin mass content be 1% and crude polysaccharide of pericarpium Citri Tangerinae mass content be 0.5%, to obtain puerarin-pericarpium Citri Tangerinae polysaccharide gel.

Example 2 Effect of different gelling Agents on wound healing of damaged skin

C57/BL mice 32 were randomly divided into 4 groups: a control group, a puerarin treatment group and a dried orange peel polysaccharide treatment group; the puerarin-pericarpium citri reticulatae polysaccharide treatment group is 8 in each group, drinking water is carried out in normal diet, skin tissues with the diameter of 1cm are taken away from the back, a skin injury model is established, then blank gel is smeared on a control group, the puerarin gel prepared in the example 1 is smeared on the puerarin treatment group, the pericarpium citri reticulatae polysaccharide gel prepared in the example 1 is smeared on the pericarpium citri reticulatae polysaccharide treatment group, and the puerarin-pericarpium citri reticulatae polysaccharide gel prepared in the example 1 is smeared on the puerarin-pericarpium citri reticulatae polysaccharide treatment group 2 times a day for 9 days. Wound healing of the damaged skin was observed every two days and the wound healing rate was calculated.

The healing of wounds on the injured skin of mice smeared with different gels is shown in FIG. 1. As can be seen from fig. 1, the healing speed of the wound of the mice in the puerarin, tangerine peel polysaccharide and puerarin-tangerine peel polysaccharide treated groups is faster than that of the control group, and the healing speed is puerarin-tangerine peel polysaccharide treated group > puerarin treated group > tangerine peel polysaccharide treated group.

The wound healing rates of the injured skin of mice smeared with different gels are shown in fig. 2. As can be seen from fig. 2, the wound healing rates of the mice treated with puerarin, pericarpium citri reticulatae polysaccharide and puerarin-pericarpium citri reticulatae polysaccharide are all higher than 70%, 78.02%, 76.36% and 91.36%, respectively, which are significantly higher than 67.60% of the control group; meanwhile, the wound healing rate of the puerarin-pericarpium citri reticulatae polysaccharide treatment group is 91.36%, which is obviously higher than that of the puerarin treatment group and the pericarpium citri reticulatae polysaccharide treatment group.

In conclusion, puerarin and pericarpium citri reticulatae polysaccharide have the effect of promoting the wound healing of the damaged skin, and compared with the single use, the puerarin-pericarpium citri reticulatae polysaccharide can be used together to more remarkably promote the wound healing of the damaged skin.

EXAMPLE 3 Effect of different gelling Agents on follicle neogenesis and epidermal thickness of skin in wound healing

C57/BL mice 32 were randomly divided into 4 groups: a control group, a puerarin treatment group and a dried orange peel polysaccharide treatment group; the puerarin-pericarpium citri reticulatae polysaccharide treatment group is 8 in each group, drinking water is carried out in normal diet, skin tissues with the diameter of 1cm are taken away from the back, a skin injury model is established, then blank gel is smeared on a control group, the puerarin gel prepared in the example 1 is smeared on the puerarin treatment group, the pericarpium citri reticulatae polysaccharide gel prepared in the example 1 is smeared on the pericarpium citri reticulatae polysaccharide treatment group, and the puerarin-pericarpium citri reticulatae polysaccharide gel prepared in the example 1 is smeared on the puerarin-pericarpium citri reticulatae polysaccharide treatment group 2 times a day for 9 days. Then, experimental mice are sacrificed by adopting a cervical dislocation method, skin tissues for healing wounds on the back of each group of mice are collected, and after fixation through paraformaldehyde, paraffin embedding is carried out, and tissue sections are made. Tissue staining was performed using a hematoxylin eosin staining kit, the method referring to kit instructions, followed by observation of the morphological state of the wound-healing skin tissue.

The morphology of the tissue for healing the skin wound of the mouse coated with different gels is shown in fig. 3, and it can be seen from the hair follicle neogenesis degree in fig. 3 that the hair follicle number in the groups healed with the puerarin, pericarpium citri reticulatae polysaccharide and puerarin-pericarpium citri reticulatae polysaccharide treatment groups is significantly increased (the arrow indicates the neogenesis hair follicle tissue), and the hair follicle number is increased to puerarin-pericarpium citri reticulatae polysaccharide treatment group > puerarin treatment group > pericarpium citri reticulatae polysaccharide treatment group. As can be seen from the degree of epidermal layer hyperplasia in FIG. 3, the degree of epidermal layer hyperplasia was reduced and the thickness was reduced (the thickness of the epidermal layer is indicated by the arrow) in the tissues healed by the puerarin, pericarpium Citri Tangerinae polysaccharide and puerarin-pericarpium Citri Tangerinae polysaccharide treated groups compared with the control group.

The hair follicle number of the tissue for wound healing of the skin of the mice smeared with different gels is shown in figure 4; the epidermal layer thickness of the tissue for wound healing of the skin of mice smeared with different gels is shown in fig. 5. As can be seen from FIG. 4, the number of hair follicles in the tissues healed by the puerarin, pericarpium Citri Tangerinae polysaccharide and puerarin-pericarpium Citri Tangerinae polysaccharide treatment groups is higher than 140/mm²Respectively, 161.0 pieces/mm²149.3 pieces/mm²And 199.3 pieces/mm²Is obviously higher than 65.1 pieces/mm of the control group²Meanwhile, the number of the hair follicles of the puerarin-dried orange peel polysaccharide treatment group reaches 199.3 per mm²Is obviously higher than the puerarin treatment group and the tangerine peel polysaccharide treatment group. As can be seen from FIG. 5, the thickness of the epithelium in the tissues healed by the puerarin, pericarpium Citri Tangerinae polysaccharide and puerarin-pericarpium Citri Tangerinae polysaccharide treated groups was less than 50 μm, 49.9 μm, 41.6 μm and 49.7 μm respectively, which were significantly less than 80.5 μm in the control group, and the decrease in thickness of the epithelium in the tissues healed by the puerarin-pericarpium Citri Tangerinae polysaccharide treated group was not significantly different from those of the puerarin treated group and the pericarpium Citri Tangerinae polysaccharide treated group.

In the neogenetic skin tissue, more neogenetic hair follicle tissue and less epidermal layer thickness accretion represent that the healed tissue enters the remodeling stage earlier, and thus a faster recovery effect is achieved. The combination of the puerarin and the pericarpium citri reticulatae polysaccharide can more obviously promote the recovery of the number of the hair follicles in the tissues healed by the wounds of the damaged skin and promote the neogenesis of the hair follicles compared with the single use of the puerarin and the pericarpium citri reticulatae polysaccharide. Meanwhile, the puerarin, the tangerine peel polysaccharide and the puerarin-tangerine peel polysaccharide treatment group can reduce the hyperplasia degree of the epidermis layer after treatment, so that the thickness of the new skin is reduced.

The invention also performs experiments on various medicament-carrying gels prepared from puerarin and pericarpium citri reticulatae polysaccharide in different mass ratios. The blank gel is prepared according to the preparation method of the blank gel in the embodiment 1, then the drug-loaded gels are respectively prepared according to different mass ratios of puerarin and pericarpium citri reticulatae polysaccharide, and the mass contents of the puerarin and the pericarpium citri reticulatae polysaccharide with different mass ratios are shown in the table 1.

TABLE 1 Mass content of Puerarin and Citrus reticulata polysaccharide in different mass ratios

The effect of each gel on wound healing of damaged skin and on hair follicle neogenesis and skin epidermal thickness in wound healing of skin was tested using the methods of examples 2 and 3 and the results show that:

the wound healing rate of the puerarin-pericarpium citri reticulatae polysaccharide treatment group is higher than 80% when the mass ratio of puerarin to pericarpium citri reticulatae polysaccharide is 1:10, 1:5, 2:5, 5:1 and 10: 1; the number of hair follicles in the healed tissue is higher than 175 per mm²Is obviously higher than the control group, the puerarin group and the pericarpium citri reticulatae polysaccharide group; the epidermal thickness in the healed tissue was below 50 μm, significantly lower than in the control group.
