The traditional Chinese medicine composition is used for treating male erectile dysfunction and insufficiency of kidney yang, impotence, spermatorrhea, premature ejaculation and sexual dysfunction in oligospermia and asthenospermia, can be used for symptomatically improving the weakness of male middle-aged and elderly people, has a long-term effect and stability after treatment, is superior to other treatment medicines and treatment technologies in modern medicine, and has a wide application prospect. Wide clinical value and commercial value are realized.

The present application relates to the technical field of medical devices, in particular to a kind of external device for treating male erectile dysfunction, including outer tube, and the negative pressure pump and internal inner tube of the internal inside being arranged at the front end of outer tube,It also includes ball hinge seat, movably connected at the rear end of outer tube, and there is silica gel sealing ring at the opening of its rear end;Control center, installed at the front end inside outer tube, and installed at the output end of negative pressure pump, control center is connected with temperature control sensing device, temperature control sensing device is installed on the I-shaped connecting seat at the rear end of inner tube, solve the single negative pressure control mode of existing device, manually cannot be accurate control pressure and cause tissue damage or affect erection effect, the pressure program of automatic version is fixed, complex structure, poor portability, and cannot be adapted to the angle change after penis erection, easily cause compression pain, air leakage pressure loss;Lack of auxiliary physical stimulation, limited efficacy;In addition, local hypothermia under negative pressure causes body discomfort, also can contract blood vessels, hinder blood perfusion and erection maintenance problem.

The application belongs to the field of traditional Chinese medicine, and particularly relates to a time-delay spray containing dry toad extract and toad oil and a preparation method thereof. The time-delay spray provided by the application can significantly treat male erectile dysfunction. The time-delay spray prepared by the application has the advantages of direct action, quantitative drug delivery, and no contact to avoid drug pollution. The application realizes the transformation of waste into treasure of toad oil, fully excavates the medicinal value of toad oil, further improves the rational utilization system of toad resources, and provides a practical scheme for efficient development of toad medicinal resources.

Provided are stable, concentrated, and palatable solutions suitable for sublingual and / or transurethral administration containing tadalafil, with or without other active ingredients to address comorbidities, in a liquid vehicle or solvent selected from propylene carbonate, 2-pyrrolidone, dimethyl isosorbide, dimethyl acetamide, n-methyl-2-pyrrolidone, ethanol, water, oleic acid, and isopropyl myristate. The solutions have low irritancy for sublingual tissues and a-are compatible with commercial atomizers. The invention is further directed to methods of treating male erectile dysfunction and / or comorbidities by administering an effective amount of the pharmaceutical formulations comprising tadalafil, with or without other active ingredients, to a patient in need of such treatments.

The invention provides an application of an active peptide in treating male erectile dysfunction. Specifically, the invention provides a PDE-5 inhibitory active peptide P-C-5, and the active peptide can well inhibit the activity of PDE-5 in human primary cavernous smooth muscle cells and increase the concentration of cGMP in the smooth muscle cells. Mouse experiments prove that the polypeptide can well improve the sexual capacity of mice. And the polypeptide can overcome the common side effects of common erectile dysfunction medicines, such as headache, flushing, stomach discomfort, muscular pain, back pain and nausea. The polypeptide can also be combined with other drugs for ED treatment, and the application prospect is wide.

The present application provides a polypeptide composition and its use in treating male erectile dysfunction. Specifically, the polypeptide composition contains an erectile peptide screened and identified by the present application, which has good anti-oxidation and anti-fatigue properties, can effectively promote penile erection, increase testosterone level, effectively treat erectile dysfunction, and has a wide application prospect.

The application discloses a kind of stem cell exosome based on targeted fusion polypeptide modification, preparation method and its application in treating male erectile dysfunction.The exosome is anchored on the surface by chemical coupling technology with specific targeted fusion polypeptide (sequence: EPLQLKM-GGGGS-DPPV), which enhances its targeting to cavernosal smooth muscle cells;At the same time, by loading anti-TrkA monoclonal antibody (TrkA-2E7-HL) through electroporation method, the fibrosis pathway mediated by nerve growth factor (NGF) is inhibited.The exosome is induced by antioxidant culture medium to induce umbilical cord mesenchymal stem cells to secrete, which significantly improves its antioxidant activity.Experiments show that the erectile function (ICP / MAP ratio) of the exosome after modification is increased to 0.79±0.05 in a diabetic ED rat model, the fibrosis area is reduced to 9.2±1.6%, and the NO secretion level is increased by 3.5 times compared with ordinary exosome.The application realizes effective reversal of ED pathological process through polypeptide targeting, antibody synergy and antioxidant triple mechanism, and has significant novelty and clinical transformation potential.
