This invention belongs to the field of traditional Chinese medicine, specifically relating to a topical delay spray and its preparation method. The invention uses the dried epidermis of the Huaxi toad (with the toad venom removed), and extracts it efficiently through a combination of water and alcohol extraction. Male silkworm moth oil can nourish and strengthen the body, tonify the liver and kidneys, and combat fatigue; studies have shown that male silkworm moth oil can effectively treat kidney yang deficiency. This invention combines the synergistic effects of toad skin extract and male silkworm moth oil to prepare a delay spray that can significantly treat premature ejaculation and erectile dysfunction in men. This preparation has the advantages of direct action, sustained release, avoidance of drug contact, and simple operation. This invention further improves the rational utilization system of toad resources, provides a practical solution for the efficient development of toad medicinal resources, and significantly reduces production and clinical application costs.

This invention relates to an oral nanomedicine antigen delivery system and its construction method and application, belonging to the field of oral nanomaterials technology; the construction method includes the following steps: (1) preparation of OM nanoparticle suspension; (2) preparation of cationic liposome suspension; (3) preparation of cationic liposome suspension loaded with OM / BF; (4) construction of oral nanomedicine antigen delivery system. This invention breaks through multiple barriers in the gastrointestinal tract, improves drug bioavailability, and achieves precise immune tracking through the OVA tumor antigen model, simulating in vivo anti-tumor CTL response, thereby exerting anti-tumor effects synergistically at the cellular, tissue, and immune levels, effectively solving the problems of poor water solubility and low delivery efficiency of the active ingredient bufotoxin in traditional Chinese medicine. At the same time, through macrophage-mediated immune regulation and precise drug release, it improves targeting and treatment efficiency, opening up a new avenue for tumor immunotherapy with oral nanomedicine.

This invention discloses a composition and its preparation method for treating human papillomavirus (HPV) and cervical intraepithelial neoplasia (CIN), belonging to the field of traditional Chinese medicine technology. The formula consists of 6-15 parts of American cockroach, 5-11 parts of hawthorn, 5-11 parts of chicory, 3-9 parts of *Scutellaria baicalensis*, 8-20 parts of *Sophora flavescens*, and 6-15 parts of *Cnidium monnieri*, and also contains 0.01-1 parts by weight of toad venom. The dosage form is one or more of the following: external gel, rinse, foam, suppository, and film preparation. It has high safety and is suitable for HPV infection and CIN changes, solving the problem of poor efficacy in existing treatments.

This invention belongs to the field of biomedical technology, specifically relating to an ointment and its application. The toad oil used in this invention differs significantly in composition from toad venom, and its ointment is effective for various acute and chronic pain conditions. Animal experiments have confirmed that the toad oil ointment significantly reduces the frequency and delays the onset of acetic acid-induced writhing responses, demonstrating a clear analgesic effect. Clinical studies have shown that this ointment is rapidly effective and has a definite therapeutic effect on acute gout attacks, postherpetic neuralgia, and arthritis-related pain and swelling. The formulation effectively improves drug retention and user comfort, and no skin irritation has been observed. This development achieves comprehensive utilization of toad resources, providing an example for the sustainable development of traditional Chinese medicine and the efficient utilization of biological resources.

The application belongs to the field of traditional Chinese medicine, and particularly relates to an external use delayed oil agent and a preparation method thereof. The dried skin of the Visternotus limnocharis which has scraped toad venom is combined with the male silkworm moth which has the functions of tonifying liver and kidney, strengthening yang and astringing essence to significantly improve male premature ejaculation and erectile dysfunction through water extraction and alcohol extraction. The male silkworm moth oil has unique promotion potential and development potential. The application combines the toad skin and the male silkworm moth oil to prepare the delayed oil agent, significantly improves male premature ejaculation and erectile dysfunction, and has the characteristics of direct action and simple operation. The preparation cost is low.

This invention discloses the application of bufotoxin lactones in the preparation of anti-IHNV products, belonging to the field of biomedical technology. This invention is the first to discover and confirm that four bufotalin-based drugs (bufotalin, bufotalin ester, bufotalin, and bufotalin) have significant anti-IHNV effects: their IC50 values ​​against IHNV in vitro range from 0.0879 to 0.1809 μM, with selectivity indices all greater than 110. After 48 hours of treatment, they can reduce viral RNA expression by 110 to 173 times and viral titer by 4.36 to 5.15 lg; they also show broad-spectrum inhibitory effects against different genotypes of IHNV, such as LN-15, QH-17, and Blk94; in a rainbow trout in vivo model, after administration of a 0.5 mg / kg dose, the cumulative mortality rate decreased from 95% in the control group to 13.3% to 21.7%, with the highest relative protection rate reaching 85.96% (bufotalin), indicating that these compounds have highly efficient, broad-spectrum, and low-toxicity anti-IHNV activity and have excellent application prospects.

The application belongs to the field of traditional Chinese medicine, and particularly relates to an external use delayed time towel agent and a preparation method thereof. The dried skin of the Chinese toad from which the toad venom has been scraped is selected, water extraction and alcohol extraction are combined, toad skin extract is efficiently extracted, and the toad skin extract is combined with male moth oil to prepare the delayed time towel agent. It is found that through the synergistic effect of the toad skin extract and the male moth oil, male premature ejaculation and erectile dysfunction can be significantly improved, and the synergistic effect of the two is much higher than that of single medicine, the medicinal effect is optimized, the core requirement of clinical application is met, the towel agent is prepared, independent packaging is achieved, and the towel agent has the characteristics of low cost, direct effect, simple operation, and difficulty in drug pollution.
