Abstract
Description
Technical Field
[0001] This invention belongs to the field of traditional Chinese medicine technology, specifically relating to a compound traditional Chinese medicine composition for treating skin warts and condyloma acuminata and its application. Background Technology
[0002] Warts are benign skin lesions caused by human papillomavirus (HPV) infection of the skin and mucous membranes. Based on clinical manifestations and location, warts are classified into common warts, flat warts, plantar warts, condyloma acuminata, and epidermal dysplasia verruciformis, among others. The source of infection for warts is infected individuals and virus carriers, primarily caused by HPV types 1, 2, and 4. Wart lesions are painful to the touch, but may also be asymptomatic. Under a skin microscope, pale yellow papules, thickened keratin rings, and round papillary hyperkeratosis with small black dots formed by ruptured capillaries are visible. The course of the disease is closely related to the body's own immunity; those with weakened immune systems have a higher incidence. Some patients may experience spontaneous remission, but patients often seek treatment due to cosmetic concerns and pain. Current treatments for warts primarily focus on destroying the wart and enhancing local or systemic immunity, including medication, physical therapy, and surgical excision. However, these treatments suffer from long treatment courses, painful procedures, high infection rates, and high recurrence rates, leading to poor patient compliance.
[0003] Commonly used topical medications include imiquimod, a small-molecule immunomodulator with immunomodulatory and indirect antiviral effects. Its antiviral action works by stimulating the body's own immunity and inducing T-cell kinase activity to enhance cellular immunity, thereby generating an immune response against HPV-infected cells. Currently, it is mainly used clinically for the treatment of condyloma acuminata of the anus and external genitalia. The main drawbacks of this treatment method are the long treatment period, difficulty for patients to adhere to, and high treatment costs, increasing the financial burden on patients. However, it is less painful and invasive, easy to administer, and can be used at home and in children. Caution should be exercised when using this treatment in patients with skin allergies.
[0004] In addition, there is salicylic acid, a keratolytic agent that works by slowly destroying virus-infected cells without affecting the production of keratinocytes. The mild stimulation it produces can trigger an immune response. It slowly destroys the epidermis infected with HPV, causing local shedding or thinning of the stratum corneum. Its advantages include minimal side effects and no scarring after lesion healing, simple operation, and low treatment cost. Its disadvantages are slow onset of action and slight skin irritation; therefore, it should be discontinued if redness or swelling occurs during use, and it should not be used on the face or scalp to avoid skin pigmentation affecting appearance.
[0005] Other treatments include interferon and cantharidin. Recombinant human interferon has functions such as inhibiting tumor cell proliferation, antiviral activity, and regulating the human immune system. Interferon combined with other treatments is safe and effective for treating single, refractory common warts and can reduce the recurrence rate. Cantharidin, extracted from the traditional Chinese medicine cantharides, can cause hyperemia and blistering of the wart epidermis. Mild pain may occur when cantharidin treatment causes blisters to form on common warts; healing is scarless. If erosion occurs during treatment, treatment should be paused for a few days before resuming.
[0006] In addition, there are laser treatments and surgical treatments. Currently, there are many treatments for skin warts, but these methods often have drawbacks such as prolonged disease course, easy scarring, residual subclinical lesions or incomplete eradication of latent HPV virus, and easy recurrence. More importantly, the drugs have strong side effects and poor patient compliance.
[0007] Chinese invention patent application CN202411128022.6 discloses a traditional Chinese medicine composition for treating flat warts, belonging to the field of traditional Chinese medicine technology. According to the weight parts, it includes the following raw materials: 9-20 parts of Forsythia suspensa, 6-20 parts of Pogostemon cablin, 6-20 parts of Eupatorium fortunei, 9-20 parts of Prunella vulgaris, 10-30 parts of Coix lacryma-jobi, 9-20 parts of Lithospermum erythrorhizon, 9-20 parts of Polygonum cuspidatum, 9-20 parts of Paeonia suffruticosa, 10-30 parts of stir-fried white hyacinth bean, 9-30 parts of Poria cocos, 9-30 parts of Atractylodes macrocephala, 6-20 parts of Ligusticum chuanxiong, 6-20 parts of Citrus reticulata peel, and 6-15 parts of Glycyrrhiza uralensis. This traditional Chinese medicine composition treats flat warts by clearing heat and detoxifying, soothing the liver and regulating qi, tonifying the spleen and resolving dampness.
[0008] The aforementioned compositions may have complex flavors or uncertain efficacy. The physiological effects of drugs are closely related to their complex chemical components. Domestic and international research on their active ingredients mainly focuses on medicinal materials and indications, with limited in-depth research on the relationship between active ingredients and their activity. Precisely simplifying the formulation is crucial for elucidating the mechanism of action, and figuring out how to break down prescriptions to achieve higher efficacy is an urgent issue to be addressed in the field of traditional Chinese medicine.

[0016] The second objective of this invention is to provide a method for preparing a compound traditional Chinese medicine composition for treating skin warts and condyloma acuminata, comprising the following steps:
[0017] (1) Press the croton seeds to extract croton oil, and obtain the residue;
[0018] (2) Add water to houttuynia cordata, bee honeycomb, cnidium monnieri and dregs, decoct to obtain decoction, add tanninase to the decoction to hydrolyze and inactivate, and obtain hydrolysate;

[0020] Preferably, the amount of tanninase added in step (2) is 0.05-0.2% of the decoction mass.
[0021] Preferably, in step (2), the enzymatic hydrolysate is concentrated into a thick paste with a relative density of 1.30~1.35 at 50°C.
[0022] Preferably, the enzymatic hydrolysis temperature in step (2) is 45-50℃, the pH of the enzymatic hydrolysis is 4.5-6.0, and the hydrolysis time is 1.5-3h.
[0023] A third objective of this invention is to provide a pharmaceutical preparation for treating skin warts and condyloma acuminata, comprising the aforementioned compound traditional Chinese medicine composition and pharmaceutically acceptable excipients.

The HPV11-positive E. coli were cultured and amplified, and then the plasmid was extracted and purified. The full-length HPV11 gene was digested with the restriction endonuclease BamHI according to the instructions of the Promega BamHI Restriction Kit.
[0125] Following the instructions of the Invitrogen T4 DNA ligase kit, linear HPV11 DNA was self-circularized using T4 DNA ligase. The self-circularized HPV11 DNA was then purified using the Promega gel and PCR product recovery and purification kit to obtain circular HPV11 DNA.
[0126] HPV11-HaCaT cells were constructed through cell transfection:
[0127] 1) Culture the cells as usual, digest and centrifuge HaCaT cells that have grown to 80% confluence, and count them. (3 × 10⁶ cells) 5 The cells were seeded into six-well plates and incubated overnight at 37°C with 5% CO2. The old culture medium in the six-well plates was then aspirated and the cells were gently rinsed twice with serum-depleted culture medium.
[0128] 2) Take 1.2 μg of the previously prepared circular HPV11 DNA and 0.4 μg of PTK-neo DNA, add them to 100 μl of serum-depleted culture medium, mix gently, and label as Solution A. Add 8 μl of Lipofectamine TM Add 2000 μL of transfection reagent to 100 μL of serum-depleted culture medium, mix gently, label as solution B, and incubate at room temperature for 5 min. Gently mix solution A and solution B, and incubate at room temperature for 20 min to obtain the Lipofectamine-DNA mixture.
[0129] 3) Add 800 μL of serum-depleted culture medium to the Lipofectamine-DNA mixture and mix gently to obtain the mixture. Add 1 mL of this mixture dropwise to the surface of HaCaT cells from step 1), gently shake to distribute evenly, and set up a blank control group. A negative control group was also set up as follows: (1) Lipofectamine was added only. TM 2000, without HPV11 DNA and PTK-neoDNA. (2) Add Lipofectamine. TM 2000 and HPV11 DNA, without PTK-neoDNA, (3) with added Lipofectamine TM 2000 and PTK-neo DNA, without HPV11 DNA, (4) without Lipofectamine TM 2000, only HPV11 DNA and PTK-neo DNA were added, (5) no treatment was added (blank control). After being placed in a 37℃, 5% CO2 incubator for 6 hours, the medium was changed, DMEM complete medium was added again, and the culture was continued.
[0130] 4) When the transfected cells reach approximately 80% confluence, digest the cells, centrifuge, resuspend the cells, and transfer them to a new cell culture plate at a 1:10 ratio. Incubate overnight at 37°C with 5% CO2. Discard the medium and replace it with DMEM medium containing 500 μg / ml G418, and continue culturing. After approximately 5 days, most of the cells in the blank control wells will have died. Replace the medium with DMEM medium containing 250 μg / ml G418 and continue culturing.
[0131] 5) Once the resistant cell clones have formed, they are digested and merged, then transferred to DMEM medium containing 250 μg / ml G418.
[0132] Continue culturing. Perform the same treatment on the negative control group cells until all cells die.
[0133] 6) Prepare a cell cryopreservation solution using 45% fetal bovine serum, 45% DMEM medium, and 10% DMSO. Collect cells in good growth condition after selection, digest and centrifuge the cells, and resuspend them in the cell cryopreservation solution. Transfer the cell suspension to cryovials to obtain HPV11-HaCaT cells. Detect the presence of HPV11 DNA in the cells using FQ-PCR.
[0134] 2.4 Effects of Compound Traditional Chinese Medicine Composition on HPV11-HaCaT Cells and HaCaT Cell Proliferation Rate: Experimental Methods:
[0135] (1) Cell culture: HaCaT cells and HPV11-HaCaT cells were cultured in DMEM medium containing 10% newborn calf serum and cultured at 37°C, 5% CO2 and saturated humidity.
[0136] (2) Experimental grouping: HaCaT and HPV11-HaCaT cells in the logarithmic growth phase were divided into Example 1-3, Comparative Example 1-4 (with different concentrations of traditional Chinese medicine compositions prepared in Example 1-3 and Comparative Example 1-4), 0.1% DMSO solvent control group, and blank control group.
[0137] (3) Cell proliferation assay: HaCaT cells and HPV11-HaCaT cells were seeded in 96-well plates (2 × 10⁻⁶ cells / well). 4 Cells were cultured overnight in wells (1 cell / well), and then different concentrations of drug solution (200 μL / well) were added to each group: the final concentrations of each example and the comparative example were 8, 4, 2, 1, and 0.5 mg crude drug / mL (diluted with DMSO), respectively. The 0.1% DMSO solvent control group had a DMSO content of 0.1%, and the blank control group had an equal volume of culture medium. Each group had 3 replicates. After culturing for 24 h, 20 μL / well of 5 mg / mL MTT solution was added, and the cells were cultured for another 4 h. The culture medium was then discarded, and 150 μL / well of DMSO was added and shaken for 10 min in the dark to fully dissolve the blue-purple precipitate. The absorbance was measured at 550 nm using a microplate reader. The cell viability of different concentration groups was calculated as: Cell viability = (Experimental group A550 / Control group A550) × 100%. The mean cell viability of each group was calculated using the data from each well. Then, the relative expression levels of HPV11E7 mRNA at a drug concentration of 1 mg crude drug / ml in Examples 1-3 and Comparative Examples 1-4 were determined using RT-PCR. The experimental results are shown in Tables 4-11.

[0154] MTT assay uses MTT [(4,5-dimethylthiazole)2,5-diphenyltetrazol bromide] to stain cells. Changes in the optical density (OD value) can be detected to determine cell viability and understand the protective effect of the drug, thus enabling quantitative analysis of efficacy. Tables 4-10 show that the compound traditional Chinese medicine compositions in Examples 1-3 and Comparative Examples 1-4, at concentrations of 1-8 mg crude drug / ml, exhibited a certain degree of inhibitory effect on HPV11-HaCaT cells and HaCaT cells. Example 1 showed the best effect, with cell survival rates of 1-67% for HPV11-HaCaT cells. This demonstrates dose-dependent characteristics.
[0155] In Table 11, compared with the 0.1% DMSO solvent control group, the relative expression level of HPV11 E7 mRNA in each example group and the comparative example group showed a certain degree of decrease. The compound traditional Chinese medicine composition of the present invention is a simplified combination of the traditional Chinese medicine preparation of Comparative Example 4. After decomposition and combination, at the same dosage, its inhibitory effect on HPV11 E7 mRNA expression is comparable. The formula is concise and effective, and has good application prospects.
