Abstract
Description
Technical Field
[0001] This invention belongs to the field of biomedical technology, and in particular relates to a traditional Chinese medicine composition for improving scanty menstruation and its application. Background Technology
[0002] Scanty menstruation is a common symptom of gynecological endocrine disorders, belonging to the category of menstrual irregularities, with a prevalence rate of up to 12% among women of reproductive age in China. It manifests as a normal menstrual cycle, but a significant reduction in menstrual flow compared to previous periods, exceeding one-third of the original flow, or menstruation lasting less than two days, with a flow of less than 30 mL, or even just spotting. The causes of scanty menstruation are complex, mainly involving uterine factors (endometrial damage / insufficient local microcirculation blood perfusion in the endometrium), ovarian factors (insufficient ovarian sex hormone secretion / anovulation), central factors (high stress, excessive exercise, etc. leading to central nervous system depression), and genetic factors. If left untreated, it can develop into amenorrhea, and in severe cases, premature ovarian failure. It can also affect the implantation and development of fertilized eggs in the endometrium, leading to recurrent miscarriages, infertility, and other adverse effects on women's fertility and physical and mental health. Therefore, early treatment of this condition is of positive significance for maintaining normal physiological function, delaying aging, and preserving fertility.
[0003] Western medicine often treats this condition with artificial cycle therapy. For those with intrauterine adhesions, hysteroscopic surgery can be chosen. However, some patients may have contraindications to hormone therapy, which can cause adverse reactions such as dizziness and nausea. Furthermore, the condition is prone to relapse after discontinuation of hormone therapy, and the treatment effect is not yet satisfactory. Traditional Chinese medicine believes that the pathogenesis of oligomenorrhea is divided into two types: deficiency and excess, with deficiency being the most common clinically (especially kidney deficiency). However, single-herb treatments are often unstable in efficacy and slow in onset, failing to meet patients' needs for safe and effective treatment options. Therefore, finding safer, more effective treatment options with fewer side effects is particularly important. Summary of the Invention
[0004] In view of this, the purpose of the present invention is to provide a traditional Chinese medicine composition for improving scanty menstruation and its application. By combining Leonurus japonicus, Dingkun Dan and scopolamine into a composition, it can improve scanty menstruation, increase menstrual flow and improve blood circulation in the endometrium.
[0005] This invention provides a composition for improving oligomenorrhea, comprising the following drugs: Motherwort injection, Dingkun Dan, and scopolamine.
[0006] Preferably, the ratio of the motherwort injection, Dingkundan and scopolamine is 2mL:14g:10mg.
[0007] Preferably, the Dingkun Dan and scopolamine are oral medications.
[0008] The present invention also provides the use of the composition in the preparation of a medicament for improving oligomenorrhea.
[0009] Preferably, the composition can increase menstrual flow.
[0010] Preferably, the composition can improve blood circulation in the endometrium.
[0011] Preferably, the motherwort injection is used alone, while the anisodamine and Dingkundan are used simultaneously.
[0012] Preferably, the motherwort injection is taken 10 days before each menstrual cycle, and the scopolamine and Dingkun Dan are taken simultaneously from day 11 to day 30 of each menstrual cycle.
[0013] Preferably, the dosage of the motherwort injection is 2 mL / time, once daily.
[0014] Preferably, the dosage of scopolamine and Dingkun Dan used simultaneously is scopolamine 10mg / time, once a day; Dingkun Dan 7g / time, twice a day.
[0015] The beneficial effects of this invention are: This invention combines Leonurus japonicus, scopolamine, and Dingkun Dan into a single composition, achieving complementary effects: Leonurus japonicus invigorates blood circulation and regulates menstruation to resolve blood stasis; scopolamine improves microcirculation and relieves smooth muscle spasms; and Dingkun Dan nourishes qi and blood to consolidate the therapeutic effect. The combined use of these three drugs effectively increases menstrual flow and improves endometrial blood circulation. Compared to single-drug treatment, this significantly improves the treatment effect for oligomenorrhea, solving the problems of unstable efficacy and slow onset of action in traditional treatments. This invention combines intramuscular injection and oral medications, allowing for precise administration in stages according to the menstrual cycle. This ensures both rapid onset of action and long-term therapeutic effect, while avoiding the side effects of long-term single-drug use, thus improving treatment safety and tolerability. The composition of this invention can directly improve core symptoms such as oligomenorrhea and short menstrual periods, improve uterine microcirculation, and enhance patients' quality of life. All drugs in the composition of this invention are approved and compliant pharmaceutical products with clear sources and controllable quality. The administration regimen is simple and easy to implement, suitable for clinical application, and provides a safe, efficient, and replicable new treatment method for oligomenorrhea.

[0036] 1.9 Statistical Methods This study used SPSS 27.0 for statistical analysis. Normally distributed continuous data were expressed as mean ± standard deviation, and independent samples t-tests were used for between-group comparisons, while paired t-tests were used for within-group comparisons. Non-normally distributed continuous data were described statistically using median and interquartile ranges, and nonparametric tests were used for between-group comparisons, while Wilcoxon signed-rank tests were used for within-group comparisons. Categorical data were expressed as percentages (%), and chi-square tests were used for between-group comparisons. 2 Test. P<0.05 indicates a statistically significant difference, and P<0.01 indicates a statistically significant difference.
[0037] 2. Results 2.1 Comparison of Basic Data There were no statistically significant differences in baseline data between the groups (P>0.05), indicating that the baseline data were comparable. See Table 1.
[0038] Table 1 Comparison of baseline data between the two groups 2.2 Menstrual blood loss score The PBAC scores and their changes after 3 months of treatment were compared between the two groups, and the results are shown in Table 2. The PBAC scores of both groups were significantly higher after 3 months of treatment than before treatment [Triple-combination group: (16.32±8.61) points vs. (33.40±22.79) points, P<0.01; Dingkun Dan group: (19.31±11.92) points vs. (31.00±18.04) points], and the improvement in PBAC scores in the triple-combination group was more significant than that in the Dingkun Dan group (P<0.01).
[0039] Menstrual blood loss mapping is a precise semi-quantitative visual scoring system for assessing menstrual blood loss and is the most commonly used evaluation tool in research on menstrual disorders. The results of this trial showed that both groups experienced significant increases in menstrual blood loss after 3 months of treatment compared to before treatment, and the improvement was significantly greater in the three-drug combination group than in the Dingkun Dan group, indicating that the combined use of the three drugs can better improve oligomenorrhea and increase menstrual flow.
[0040] 2.3 Traditional Chinese Medicine Syndrome Scoring No significant differences were found in the TCM syndrome scores between groups or within groups. See Table 2.
[0041] 2.4 General health status (SF-36) score No significant differences were found in the patients' overall health scores between or within groups. See Table 2.
[0042] Table 2 Comparison of the two sets of scoring indicators 2.5 Changes in sex hormone levels After 3 months of treatment, no significant differences were found in FSH, LH, and E2 levels between or within the two groups. See Table 3.
[0043] Table 3 Comparison of sex hormone levels between the two groups 2.6 Changes in endometrial markers After 3 months of treatment, the peak systolic velocity (PSV) of the three-in-one group increased, while the pulsatility index (PI) and resistance index (RI) decreased, and the differences before and after treatment were significantly different from those in the Dingkun Dan group [PSV: P=0.037; PI: P<0.01; RI: P=0.021]. See Table 4.
[0044] Uterine artery perfusion and hormone levels can influence each other: increased uterine artery blood flow resistance can lead to insufficient blood supply to the endometrium, directly affecting endometrial growth, and can also affect ovarian hormone secretion, thus indirectly affecting endometrial growth. Conversely, estrogen plays an important role in regulating uterine artery blood flow, and its mechanism of action includes dilating the uterine artery to reduce vascular resistance, thereby improving endometrial growth and ovarian blood supply. Clinically, ultrasound examination can detect the dynamic parameters of uterine artery blood flow, including RI, PI, and PSV. Low RI and PI values in the uterine artery indicate low vascular resistance and good ovarian and uterine blood perfusion. In this trial, compared with the Dingkun Dan group, the three-in-one group showed a more significant increase in PSV and a lower decrease in RI and PI after treatment, suggesting that the three-in-one therapy improved endometrial blood supply (blood circulation) in patients with oligomenorrhea.
[0045] Table 4 Comparison of endometrial parameters between the two groups 2.7 Safety Index Results and Adverse Reactions Specific safety indicators were collected from the two groups of patients before and after treatment. The results showed that there were no significant differences in blood test results before and after treatment in either group, and there were also no differences between the groups at any follow-up time points. See Table 5.
[0046] Table 5 Comparison of the two groups of safety indicators No serious adverse events occurred in any of the subjects participating in this trial after medication.
[0047] In summary, the combination of the present invention, namely "Leonurus japonicus + Scopolamine + Dingkun Dan", when used in combination for patients with oligomenorrhea, can significantly increase menstrual flow and endometrial blood supply, with considerable long-term efficacy and safety, and has further promotion value.
[0048] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
