Plant essence for preventing, treating and repairing scar hyperplasia and preparation method thereof
Technical Field
The invention relates to the field of biological medicines, in particular to a plant essence for preventing and repairing scar hyperplasia and a preparation method thereof.
Background
Scars are one of the most common complications after wound healing and are always a difficult point and a hot point for research in the field of surgical repair. Not only does excessive scar proliferation affect the cosmetic appearance of the patient, but the resulting spasms can lead to varying degrees of dysfunction, placing a heavy economic and psychological burden on the later treatment of such patients.
Scar formation is actually only a stage in skin trauma, and therefore understanding the process of skin healing is a critical loop for scar repair. From a pathological point of view, healing of skin wounds generally falls into four stages: hemostasis, inflammatory responses, cell proliferation/matrix precipitation and skin tissue remodeling, these phases being mediated by a cascade of immune cells and signaling molecules. In the process of skin wound healing, fibroblasts, keratinocytes and epithelial cells are accumulated at the site of injury, and scar formation begins in the third phase of wound healing. In this stage, fibroblasts differentiate into myofibroblasts, which secrete and synthesize new ECM (extracellular matrix). The new ECM is remodeled to form scar tissue. Meanwhile, cytokines secreted by leukocytes play a direct role not only in the initial aggregation of fibroblasts, but also play a key role in mediating the development of scar formation in general inflammatory responses. At present, the commonly used treatment techniques in the aspect of scar treatment include surgical operations such as skin grafting, laser treatment, skin dilator treatment, excision and suture, grinding, treatment by using simple hormone drugs such as dexamethasone, freezing treatment and the like. The technologies relieve the symptoms of patients to different degrees, but the non-drug treatment in the methods has the defects of higher cost, more pain of patients, long operation treatment time and the like, and the diseases are easy to relapse after recovery. The treatment with the steroid hormone medicines such as dexamethasone may cause harm to the body and even cause sterility, osteoporosis and the like.
The existing products for preventing and repairing various scars have certain limitations. The invention provides a plant essence for preventing and repairing scar hyperplasia and a preparation method thereof. The product combines the traditional Chinese herbal medicine and western pharmacology, selects the traditional Chinese medicines of pseudo-ginseng, liquorice and sophora flower which have the functions of removing blood stasis, promoting tissue regeneration, resisting inflammation, sterilizing, activating immunity, whitening and lightening spots, and enriches dammarane type tetracyclic pentaplenin (ginsenoside Rb) by an extraction and purification technology1、Rg1Rd, notoginsenoside R1Etc.), glycyrrhizin and flavone, rutin and plant polysaccharide, etc., can effectively activate immune cell population of wound parts, inhibit macrophage polarization, inhibit expression of inflammatory factors and trend factors, inhibit proliferation and differentiation of fibroblasts, reduce ECM (extracellular matrix) deposition, promote regeneration of capillary vessels around pathological changes, improve microcirculation, prevent and repair scar hyperplasia from inside to outside, and has high safety.

The product of the invention is rich in dammarane type tetracyclic pentadecanoid saponins (ginsenoside Rb)1、Rg1Rd, notoginsenoside R1Etc.), glycyrrhizin and flavone, rutin and plant polysaccharide, etc., can effectively activate immune cell population of wound parts, inhibit macrophage polarization, inhibit expression of inflammatory factors and trend factors, inhibit proliferation and differentiation of fibroblasts, reduce ECM (extracellular matrix) deposition, promote regeneration of capillary vessels around pathological changes, improve microcirculation, prevent and cure scar hyperplasia from inside to outside, etc. The possible mechanism of action is shown in figure 1. In order to verify the effect of the plant essence of the invention in preventing and repairing scar hyperplasia, the following tests are carried out:
anti-inflammatory Activity assay
A large number of scientific reports prove that the generation of acute and chronic inflammation, wound healing and scar formation are directly and indirectly related, inflammatory factors can mediate the proliferation and differentiation of fibroblasts and promote the secretion and deposition of ECM, and are key targets for scar hyperplasia, so that the inhibition and reduction of inflammatory response are important links for preventing and repairing scar hyperplasia, wherein TNF- α, I L-6 and I L-8 are key inflammatory expression factors.
L PS (L ipopolysaccharide, lipopolysaccharide used at a concentration of 1. mu.g/ml) was used in the experiment to induce an inflammatory response in RAW264.7 (mouse mononuclear macrophages), the product of example 2 of the invention (used at a concentration of 500ug/ml) was used for treatment, and finally the expression of the inflammatory factors TNF- α, I L-6 and I L-8 was evaluated using E L ISA (Enzyme linked immunosorbent assay). The results of the experiment are shown in FIG. 2.
As can be seen from the test results, when L PS is used for inducing RAW264.7, the expressions of TNF- α, I L-6 and I L-8 are remarkably increased compared with a blank Control group (Control), which indicates that L PS induces inflammation, and when the product is treated by the invention of example 2 with the concentration of 500 mug/ml, the expressions of TNF- α, I L-6 and I L-8 are greatly reduced, which indicates that the product of the invention has remarkable inhibition effect on the expression of inflammatory factors induced by L PS.
Second, animal body test for inhibiting scar hyperplasia (rabbit ear model)
1. Influence on scar area
The test uses 10 healthy New Zealand rabbits (2.0-2.2 kg body weight) which are divided equally into two groups: a circular puncture wound (D ═ 1CM) was made in the ear belly of both rabbits in the blank group (5) and treatment group (5) to create a scar model. Starting on day 14 of the wound, the treatment group treated the wound daily with a 2% by weight sterile aqueous solution containing example 2 for 10 days, and the blank group was treated with an equal amount of 1% physiological saline for 10 days. Scar area differences were measured at day 30. The results are shown in FIG. 3 as the mean standard deviation.
From the test results, the average scar area of the treatment group treated by the example 2 is reduced by 38% compared with that of the blank group, which shows that the product of the invention has the function of inhibiting the generation of scars and can obviously reduce the hyperplasia of scars.
2. Influence on collagen synthesis
In the wound healing process, the production of collagen can be said to be a twolip sword, which is essential for the healing process on the one hand; on the other hand, overproduction and excessive deposition of collagen can lead to excessive scar proliferation. While the production of collagen and ECM is mainly mediated by the hyperproliferation and secretion of myofibroblasts. Numerous reports on scar-related scientific research have also demonstrated that: by inhibiting proliferation and differentiation of fibroblasts, excessive production of collagen and ECM can be inhibited, thereby effectively inhibiting proliferation of scar tissue. In the test, scar tissues in a healthy group, a control group and a treatment group treated in the embodiment 2 of the rabbit ear model are sampled, and the content of collagen I and collagen III is measured to evaluate the influence of the product on the collagen, so that the inhibition effect of the product on scar hyperplasia is further verified.
In the two groups of rabbit ear models, hypertrophic scar tissue of one rabbit ear in each group is sampled respectively at the 7 th day and the 30 th day after treatment, and simultaneously, tissue of any healthy part is sampled, namely, the rabbit ear is divided into a healthy group, a blank group and a treatment group at each time point, after the sample passes through the treatment, the content of collagen I and collagen III is measured on the treated sample by using E L ISA (Enzyme linked immunosorbent assay), and the test results are shown in fig. 4 and fig. 5.
From the test results, the contents of collagen I and collagen III in the scar tissue of the treatment group treated by the product of the invention are greatly reduced compared with the blank group, and the concentration of the scar tissue is closer to that of the healthy group. This shows that the test product can effectively inhibit the generation of collagen, thereby inhibiting the excessive proliferation of scars.
