Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of traditional Chinese medicine, and specifically relates to a traditional Chinese medicine composition and medicine for promoting wound healing. Background Art
[0002] Skin wound healing refers to the healing process after the skin tissue is severed or damaged due to some kind of effect, including the regeneration of various tissues, the proliferation of granulation tissue, and the complex combination of scar tissue formation. The mildest wound is limited to the epidermis of the skin. Slightly more serious wounds involve the rupture of the skin and subcutaneous tissue, and the appearance of wounds; more serious wounds may involve the rupture of muscles, tendons, nerves, and fractures.
[0003] When trauma occurs, there are different degrees of tissue necrosis and vascular rupture and bleeding in the local area. Tissue factor and intracellular calcium ions are released, which initiates the exogenous coagulation pathway, and finally fibrin clots are generated and entrain a large number of platelets. After thrombosis, it blocks the site of trauma, forming a barrier to prevent microbial invasion and providing a scaffold for the next step of cell infiltration. At this time, growth factors recruit neutrophils, monocytes, and fibroblasts into the wound. These constitute the beginning of the inflammatory phase. That is, in the early stage of trauma, neutrophils enter the wound surface, remove cell debris and bacteria entering the wound surface, and prevent the wound surface from being infected. Then, at the beginning of the proliferation phase, fibroblasts enter the wound surface, synthesize glycosaminoglycans, proteoglycans, and collagen, participate in the formation of a new extracellular matrix of granular tissue, and begin to form new blood vessels and granulation tissue. The remodeling phase overlaps with the proliferation phase. In the early stage, the matrix composed of fibrin, leukocytes, and fibronectin is decomposed and replaced by proteoglycans and collagen (types I and III), which are hinged together through enzymatic reactions, increasing the toughness and tensile strength of the wound. At the same time, fibroblasts also transform into myofibroblasts, and in the final stage, fibroblasts and endothelial cells undergo apoptosis, and ultimately, the wound heals.
[0004] In clinical observation, the symptoms are congestion, serous exudation, local redness and swelling in sequence; the blood and exudate from the wound then coagulate into lumps or scabs; then the entire layer of skin and subcutaneous tissue at the contraction edge moves toward the center, new granulation tissue and skin are generated, and the wound surface shrinks.
[0005] At present, the main drug treatments for wound repair include: antibiotics, wound dressings, chemical drugs such as cytokines, and some Chinese medicine combinations or Chinese medicine monomers. The role of antibiotics is to inhibit bacteria and prevent wound infection; wound dressings such as band-aids and gauze mainly provide a physical barrier to prevent wound infection; collagen excipients, interleukins, etc. accelerate the course of wound repair; Chinese medicine single volume asiaticoside tablets are for oral use; the mechanism of action of Chinese medicine combinations is more complicated, due to the complexity of the ingredients and the synergistic effects between the components.

[0110] Experimental Results
[0111] The results are shown in Table 2 below.
[0112] Table 2 In vitro inhibition rate against Staphylococcus aureus and Pseudomonas aeruginosa
[0113]
[0114]
[0115] The results show that the inhibition rates of the Chinese medicine compositions 1-3 of the present invention against Staphylococcus aureus and Pseudomonas aeruginosa are higher than those of the Centella asiatica extract and Chrysanthemum indica extract, which have the best antibacterial effects among the ingredients, and are higher than those of the commercially available Kangfuxin liquid at the same total mass, among which composition 1 has the best antibacterial effect.
[0116] Compared with the Chinese medicine composition 1 of the present invention, the control composition 1 has the same types of raw materials but different ratios of raw materials, which leads to a decrease in the inhibition rate of Staphylococcus aureus and Pseudomonas aeruginosa, indicating that the ratio of raw materials in the prescription will significantly affect the synergistic effect between the raw materials, thereby affecting the antibacterial effect of the Chinese medicine composition.
[0117] Compared with the Chinese medicine composition 1 of the present invention, the control composition 2 adds 10 parts of Angelica dahurica, 10 parts of Rehmannia glutinosa, and 10 parts of Saposhnikovia divaricata on the basis of the formula of the Chinese medicine composition 1 of the present invention. As shown in Table 2, the addition of other raw materials does not increase the antibacterial rate of the Chinese medicine composition.
[0118] Compared with the Chinese medicine composition 1 of the present invention, the control composition 3 deleted Platycodon grandiflorum and frankincense from the prescription, and its inhibition rate on Staphylococcus aureus and Pseudomonas aeruginosa was significantly reduced, even lower than that of Centella asiatica extract and Chrysanthemum indici extract.
[0119] Compared with the Chinese medicine composition 1 of the present invention, the control composition 4 uses Angelica dahurica which also has the effect of reducing swelling and draining pus to replace Platycodon grandiflorum, and Myrrh which has the effect of promoting blood circulation and relieving pain to replace Frankincense to compound with Centella asiatica, Lithospermum officinale, Bletilla striata, Chrysanthemum indica and Folium Isatidis. As shown in Table 2, the inhibition rate of the control composition 4 on Staphylococcus aureus and Pseudomonas aeruginosa is significantly lower than that of the present invention composition 1. This indicates that Platycodon grandiflorum, Frankincense, Centella asiatica, Lithospermum officinale, Bletilla striata, Chrysanthemum indica and Folium Isatidis can better cooperate with each other to improve the antibacterial rate of the Chinese medicine composition.

[0134] Experimental methods
[0135] Modeling and grouping
[0136] Thirty-nine SPF SD rats that passed quarantine were selected, and the acute trauma model was established by removing the full-thickness skin of the rats. Before modeling, the hair on the back of the rats was removed with a shaver or depilatory cream, and the shaved area was 3.0cm*3.0cm. The hairless skin was checked for damage due to hair removal. If it was damaged, it was not suitable for the experiment. After shaving, the animals were anesthetized with isoflurane. After anesthesia, a circular skin defect with a diameter of about 7mm-10mm was made on the back of the rat with a skin sampler, and then the fascia layer was bluntly destroyed with a scalpel or surgical scissors and tweezers. After modeling, the wound was hemostatic and disinfected with iodine. The modeling day was 0d.
[0137] After the postoperative wound model was prepared, the animals were randomly divided into 13 groups, each with 3 animals: low-dose group of composition 1 of the present invention, medium-dose group of composition 1 of the present invention, high-dose group of composition 1 of the present invention, extract groups of each component, positive control group, blank control group (blank matrix), model control group (no treatment). When making animal models, prototype skin defect wounds need to be made on both sides of the spine of the rats. In addition, the shaved area on the back without wound treatment can be used as a control for clinical observation.
[0138] The dosage setting and administration are shown in Table 4:

[0143] Observation of physical signs and body weight of rats.
[0144] The rats' physical signs were observed after administration every day. The observation indicators included: animal appearance, behavioral activities, secretions, excretions, diet, death (number of deaths, time of death, pre-mortem reaction), etc. The body weight was measured once a week before administration and during continuous administration and recorded in the corresponding table.
[0145] Observation of the appearance of rat back wounds and determination of wound healing rate.
[0146] During the modeling and drug administration period, the wound was observed with the naked eye every day to see if there were inflammatory symptoms such as blood, inflammatory pus, and swelling. The scab of the wound was observed and the relevant conditions were recorded. The wound healing of rats in each group was observed on the day of modeling D0, the day of drug administration (D1), D3, D7, D11, and D14 after drug administration. The wound healing of the back wound of the rats was photographed and recorded. The JPEG format image data was obtained using Image-J image processing and analysis software to evaluate the wound healing. After using color and contrast filters to enhance the image, the red wound was selected as the measurement area based on the difference between the red wound and the background skin color, the wound area was measured, and the wound healing rate was calculated. Wound healing rate = (total area of the original wound-unhealed wound area) / total area of the original wound * 100%.
