It serves not only as the passage for menstruation and childbirth but also as the organ for sexual intercourse. Its structure consists of a mucosa, muscular layer, and adventitia, and it is highly elastic. The maintenance of normal vaginal physiological function is closely related to the normal vaginal microecological state; ovarian function, normal vaginal structure, vaginal microecological environment such as vaginal pH (normal range 3.8–4.4), microbial distribution, local cytokines, and immune function are all important factors affecting vaginal physiological function.

[0003] The invention disclosed in CN104548071A is a recombinant human collagen vaginal gel for vaginal dryness and its preparation method, comprising the following components in the indicated mass concentrations: recombinant human collagen 0.05-1%; poloxamer 4071 0-30%; poloxamer 188 0.5-6%; sodium hyaluronate 0.1-2%; glycerin 1-4%; antibacterial preservatives: phenoxyethanol 0.1-1%, sodium methylparaben 0.05-3%, sodium propylparaben 0.01-2%; water balance. As shown in the invention, the existing product can increase vaginal elasticity and improve vaginal atrophy; reduce dyspareunia and improve sexual satisfaction; improve vaginal dryness by increasing secretions and vaginal moisture, and repair itching, burning, and skin cracking caused by dryness; and alleviate vulvar and vaginal dryness and stinging symptoms. However, this product mainly improves symptoms through mechanisms such as restoring epithelial cell morphology with recombinant human collagen and moisturizing with sodium hyaluronate. The types of ingredients are relatively simple, and the synergistic effect is limited. Summary of the Invention

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] See also Figure 1-2 The present invention provides the following multiple technical solutions:

[0030] First implementation method: Preparation of SOD oil mixture

[0031] Accurately weigh 0.1 g of superoxide dismutase (SOD), 10 g of deep-sea fish oil, 5 g of vitamin E, 3 g of squalane, 1 g of sodium hyaluronate, 0.5 g of chitosan quaternary ammonium salt, 1 g of phytosterol, 0.1 g of lavender essential oil, 0.1 g of tea tree essential oil, and the remainder is purified water, and prepare a mixture of 100 g.

[0032] First, place the deep-sea fish oil, vitamin E, squalane, and phytosterols in a container and stir for 30 minutes at a stirring speed of 200 rpm under a constant temperature water bath at 50°C to ensure that all components are fully mixed to form a uniform oil phase.

[0033] Sodium hyaluronate and chitosan quaternary ammonium salt were slowly added to an appropriate amount of purified water and stirred at 100 rpm for 20 minutes at 30°C until completely dissolved to form an aqueous phase.

[0034] At 40°C, slowly pour the oil phase into the aqueous phase while simultaneously turning on high-speed stirring at 800 rpm and emulsifying for 30 minutes to ensure a uniform emulsion.

[0035] After the lotion has cooled to room temperature, add lavender essential oil and tea tree essential oil, and continue stirring for 10 minutes to evenly disperse the essential oils.

[0036] The prepared SOD oil mixture is subjected to quality testing. After all indicators are qualified, it is aseptically packaged to make a gel.

[0037] Clinical Application: Twenty female patients aged 35-50 years with symptoms of vaginal atrophy and dryness were selected. Patients used the gel prepared in this embodiment once daily, 2 grams each time, for one course of treatment (10 days). After use, changes in vaginal elasticity were measured using a vaginal elastography device, and patients were also asked to subjectively evaluate the relief of vaginal dryness. Results showed that 12 patients experienced significant relief of vaginal dryness and increased vaginal elasticity; 6 patients showed some improvement; and 2 patients showed no significant effect, with a total effective rate of 90%.

[0038] Second implementation method: Preparation of SOD oil mixture: Weigh 0.5 g of superoxide dismutase (SOD), 15 g of deep-sea fish oil, 7 g of vitamin E, 5 g of squalane, 2 g of sodium hyaluronate, 1 g of chitosan quaternary ammonium salt, 2 g of phytosterols, 0.3 g of lavender essential oil, 0.3 g of tea tree essential oil, with the remainder being purified water, for a total of 100 g. Prepare the SOD oil mixture gel using the same preparation process as in the first implementation method.

[0039] Clinical Application: Thirty patients aged 40-55 years with vaginal atrophy and dryness were selected. Patients used the gel prepared in this embodiment twice daily, 2.5 grams each time, for two consecutive courses of treatment (20 days). After use, using the same testing method, 25 patients showed significant improvement in vaginal atrophy and dryness symptoms and a marked increase in vaginal elasticity; 4 patients experienced symptom relief; and 1 patient showed no improvement, with a total effective rate of 96.7%.

[0040] The third implementation method: Preparation of the SOD oil mixture: Weigh 1 gram of superoxide dismutase (SOD), 20 grams of deep-sea fish oil, 10 grams of vitamin E, 8 grams of squalane, 3 grams of sodium hyaluronate, 2 grams of chitosan quaternary ammonium salt, 3 grams of phytosterols, 0.5 grams of lavender essential oil, 0.5 grams of tea tree essential oil, with the remainder being purified water, to prepare a 100-gram mixture. Following the established preparation process, the SOD oil mixture gel is obtained.

[0041] Clinical Application: Twenty-five patients aged 30-45 years with related symptoms were selected. Patients used the gel prepared in this embodiment twice daily, 3 grams each time, for one course of treatment (15 days). Testing showed that vaginal atrophy and dryness symptoms essentially disappeared in 20 patients, and vaginal elasticity returned to normal; symptoms were significantly alleviated in 4 patients; and the effect was moderate in 1 patient, with a total effective rate of 96%.

[0042] Fourth implementation method: Comparative Example 1 (lacking SOD component)

[0043] Preparation of the mixture: Weigh 10g of deep-sea fish oil, 5g of vitamin E, 3g of squalane, 1g of sodium hyaluronate, 0.5g of chitosan quaternary ammonium salt, 1g of phytosterols, 0.1g of lavender essential oil, 0.1g of tea tree essential oil, with the remainder being purified water, for a total of 100g. The preparation method is the same as in the first embodiment, to prepare a gel.

[0044] Clinical Application: Twenty patients with similar age and symptoms to those in Example 1 were selected. Patients used the gel once daily, 2 grams each time, for one course of treatment (10 days). After use, only 6 patients experienced slight relief of vaginal dryness symptoms with almost no change in vaginal elasticity; 10 patients showed no significant improvement; and 4 patients showed no effect, with an overall effective rate of 30%.

[0045] Fifth implementation method: Comparative Example 2 (lacking chitosan quaternary ammonium salt and phytosterols)

[0046] Preparation of the mixture: Weigh 0.1 g of superoxide dismutase (SOD), 10 g of deep-sea fish oil, 5 g of vitamin E, 3 g of squalane, 1 g of sodium hyaluronate, 0.1 g of lavender essential oil, 0.1 g of tea tree essential oil, and the remainder is purified water, for a total of 100 g. Prepare a gel according to the preparation process of the first embodiment.

[0047] Clinical Application: Twenty patients with similar symptoms were selected. Patients used the gel once daily, 2 grams each time, for one course of treatment (10 days). Results showed that vaginal dryness symptoms were relieved in 8 patients, but the effect was not significant, and vaginal elasticity was not significantly improved; 8 patients showed no significant improvement in symptoms; and 4 patients showed no effect, with a total effective rate of 40%.

[0048] The above embodiments are compared with the comparative examples, as shown in the table below:

[0049]

[0050]

[0051] The comparison between the examples and comparative examples clearly shows that the complete SOD oil mixture of the present invention is significantly more effective than the comparative product lacking certain components in improving vaginal atrophy and dryness and increasing vaginal elasticity. This fully demonstrates the importance of the synergistic effect of the components of the present invention, providing a more effective solution for treating vaginal atrophy and dryness and increasing vaginal elasticity.
