Description

Technical Field

[0001] This invention belongs to the field of modernization of traditional Chinese medicine, specifically relating to a method for preparing a Dendrobium officinale plant preparation and its application in gynecological endocrine diseases. Background Technology

[0002] Gynecological endocrine disorders such as polycystic ovary syndrome (PCOS), endometriosis with insulin resistance (EMS-IR), abnormal uterine bleeding (DUB), and perimenopausal metabolic syndrome (PMS) have become a major burden on the health of modern women. These diseases not only involve reproductive endocrine disorders, but also form a vicious cycle with systemic metabolic disorders (such as insulin resistance, chronic low-grade inflammation, oxidative stress, and gut microbiota imbalance), resulting in limited efficacy and significant side effects of existing treatments.

[0003] The current clinical treatment of gynecological diseases faces three major pain points: First, existing traditional Chinese medicines are mostly limited to the relief of single symptoms. For example, Guizhi Fuling capsules only target uterine fibroids and ovarian cysts caused by blood stasis and obstruction, and are difficult to deal with complex pathological states involving multiple systems, such as EMS-IR. Second, although Western medicine hormone therapy can suppress lesions in the short term, it will cause oxidative stress to worsen the condition. Clinical data shows that after using gonadotropin-releasing hormone agonists (GnRH-a), the SOD activity in the serum of patients decreased by 40%. Third, the vicious cycle of metabolic disorders and reproductive disorders has not been effectively blocked. For example, the risk of developing type 2 diabetes in PCOS patients is 4 times higher than that in the general population, and traditional treatment methods cannot simultaneously regulate reproductive endocrine and glucose and lipid metabolism.

[0004] To address the aforementioned issues, this invention, based on the theory of "oxidation-reduction-endocrine-metabolism" interactive regulation, has developed an innovative traditional Chinese medicine composition that combines the functions of targeting pathological processes and regulating system homeostasis. It is particularly suitable for treating gynecological endocrine diseases and related systemic dysfunctions, providing a breakthrough solution for the comprehensive treatment of complex gynecological endocrine diseases.

[0028] The dosage forms of the above-mentioned drugs for improving or treating gynecological endocrine disorders are tablets, pills, capsules, powders, or granules.

[0029] Beneficial effects:

[0030] 1. The *Dendrobium nobile* plant preparation prepared in this invention achieves autonomous gas production through an enzymatic reaction triggered in the gastric environment, allowing the preparation to float continuously in the stomach, prolonging the residence time of the active ingredients while maintaining controlled drug release. This overcomes the shortcomings of traditional oral preparations, such as short residence time and low bioavailability in the stomach. This invention co-encapsulates the *Dendrobium nobile* plant preparation and glucosinolate substrate, while separately microencapsulating myrosinase, spatially isolating it from the glucosinolate substrate to prevent pre-reaction during delivery, thus ensuring that the enzymatic reaction is triggered only in the stomach. When the preparation reaches the stomach, gastric juice permeates and releases myrosinase and glucosinolate, which undergo an enzymatic reaction to generate CO2 in situ, reducing the density of the preparation and causing it to float on the surface of the gastric juice. This achieves continuous floating in the stomach for 16 hours and sustained release of more than 85% of the drug within 24 hours.

[0031] 2. The *Dendrobium nobile* plant preparation prepared by this invention has significant advantages compared to conventional gastric flotation preparations. Traditional carbonate gas-generating systems are easily affected by individual gastric acid secretion and gastric emptying rate, resulting in short gas-generating duration and large fluctuations in flotation time. Furthermore, excessive carbonate may cause gastric discomfort. In contrast, the enzymatic gas-generating system of this invention, which generates CO2 gas from a specific substrate through enzyme catalysis, allows the preparation to float continuously, offering the following advantages:

[0032] (1) High substrate specificity: The high selectivity of black myrosinase and glucosinolate substrates avoids non-target reactions and reduces interference from byproducts;

[0033] (2) Controllable gas production rate: The release rate of enzyme and substrate can be controlled by adjusting the enzyme loading, substrate ratio or encapsulation wall material ratio, and the floating time can be extended to 16 h.

[0034] (3) High biocompatibility: The black myrosinase and glucosinolate substrates derived from cruciferous plants are generally safe and avoid the risk of electrolyte imbalance caused by carbonates. Detailed Implementation

[0061] Indicator Test

[0062] 1. Determination of in vitro buoyancy performance

[0063] The Dendrobium officinale plant preparation prepared according to this invention was added to 900 mL of 0.1 mol / L hydrochloric acid solution at a temperature of 37±0.5℃ and a rotation speed of 100 rpm. The start time and holding time were recorded.

[0064] Table 1. External Floating Performance

[0065]

[0066] As shown in Table 1, compared with Comparative Examples 1-4, the Dendrobium officinale plant preparations prepared in Examples 1-6 of the present invention can all float within 30 seconds and hold for more than 13 hours, indicating that the Dendrobium officinale plant preparations prepared in the present invention have good floating properties.

[0067] 2. Cumulative release rate determination

[0068] Two tablets of the Dendrobium officinale plant preparation prepared in this invention were placed in 900 mL of phosphate buffer at a temperature of 37±0.5℃ and a rotation speed of 100 rpm. 5 mL of the solution was taken at 12 h and 24 h and filtered through a 0.45 μm micromembrane. The absorbance values ​​of polysaccharides, flavonoids, saponins, alkaloids and volatile oils were measured at 490 nm, 415 nm, 550 nm, 525 nm and 255 nm, respectively. The cumulative release rate was calculated by substituting the values ​​into the standard curve.

[0071] As shown in Table 2, the Dendrobium officinale plant preparations prepared in Examples 1-6 of this invention exhibit stable and continuous release within 24 hours, with a release rate exceeding 85% within 24 hours. In contrast, the Dendrobium officinale plant preparations in Comparative Examples 1-4 have a release rate exceeding 80% within 12 hours, and are essentially completely released after 24 hours. Therefore, the Dendrobium officinale plant preparations prepared in Examples 1-6 of this invention not only have good solubility in the gastrointestinal tract but also possess sustained-release properties, significantly prolonging the retention time of the active ingredients in the stomach, thereby achieving a continuous and stable drug delivery effect.

[0072] Example 7

[0073] This embodiment describes the effect of the Dendrobium officinale plant preparation prepared in Example 1 on polycystic ovary syndrome, including the following steps:

[0074] S1. Three-month-old female SD rats were acclimatized for one week and then randomly divided into a blank control group (n=10) and a model group (n=50). The model group was injected subcutaneously into the neck with 0.1 mL of 60 mg / kg DHEA daily, while the control group was injected with 0.1 mL of sesame oil containing 10% anhydrous ethanol. The injections were performed for 4 consecutive weeks, and vaginal smears were examined for 5 consecutive days to determine whether the model was successful.

[0075] S2. Fifty successfully modeled rats were randomly divided into a model control group and an administration group. The administration group was given Dendrobium officinale plant preparation via intraperitoneal injection at doses of 20, 40, and 80 mg / kg, administered once every 24 hours for a total of 4 weeks. The blank control group and the model control group were given 10 mL / kg of physiological saline daily.

[0076] S3. Four weeks after administration to the group, fasting for 12 hours was performed, and blood was drawn from the tail vein to measure fasting insulin and blood glucose. The insulin resistance index was calculated. After anesthesia with 10% chloral hydrate, blood was drawn from the abdominal aorta to measure testosterone, estradiol and luteinizing hormone levels.

[0077] Comparative Example 5

[0078] The difference between this comparative example and Example 7 is that the drug used in this comparative example is chlorpheniramine.

[0082] As shown in Table 3, compared with the blank control group, the rats in the model control group had significantly increased body weight, insulin resistance index (HOMA-IR), serum testosterone and luteinizing hormone levels, and significantly decreased estradiol levels, indicating that the polycystic ovary syndrome model was successfully established. After drug intervention (Example 7 and Comparative Example 5), the rats' body weight, insulin resistance index, serum testosterone and luteinizing hormone levels were significantly reduced, while estradiol levels increased, indicating that Dendrobium officinale plant preparations can effectively improve endocrine and metabolic disorders caused by polycystic ovary syndrome and have potential therapeutic effects on polycystic ovary syndrome.

[0083] Example 8

[0084] This embodiment describes the effect of the Dendrobium officinale plant preparation prepared in Example 1 on chocolate cysts accompanied by insulin resistance, including the following steps:

[0085] S1. Three-month-old healthy, non-pregnant female SD rats were acclimatized for one week and then randomly divided into a blank control group (n=10) and a model group (n=50). The model group was fed a high-fat diet. The rat model of endometriosis was established using autologous rat endometriosis modeling. Anesthesia was administered via intraperitoneal injection of 10% chloral hydrate (0.35 g / kg). The surgical area was shaved and disinfected with povidone-iodine. A 1.5-2 cm longitudinal incision was made 1 cm from the urethral opening on the midline of the abdomen towards the head. The right uterus was removed, the middle segment of the uterus was separated and cut off, the severed ends were ligated, and the cut uterus was longitudinally dissected. After rinsing with saline, the uterus was trimmed into 0.5 cm x 0.5 cm squares and sutured to the left ovary. No active bleeding points were observed. The peritoneal cavity was rinsed with saline and penicillin solution was instilled. The peritoneal cavity was closed layer by layer. Postoperatively, penicillin dissolved in 0.9% saline (160,000 / kg) was injected for 3 consecutive days. The rats were kept in normal clean-keeping conditions. On the 4th postoperative day, estradiol valerate (0.1 g / kg) was administered. The rats were administered the sample by gavage (mg / kg) for 5 consecutive days. Four weeks after the model was established, ultrasound examination was performed to check for cyst formation in the left ovary. Fasting blood glucose was measured by blood collection from the tail vein of the rats. A blood glucose value >16.7 mmol / L was considered a successful model.

[0086] S2. Fifty successfully modeled rats were randomly divided into a model control group and an administration group. The administration group was given Dendrobium officinale plant preparation by gavage at doses of 20, 40, and 80 mg / kg, administered once every 24 hours for a total of 4 weeks. The blank control group and the model control group were given 10 mL / kg of physiological saline daily.

[0087] S3. After 4 weeks of oral administration, the rats were fasted for 12 hours, anesthetized with 10% chloral hydrate, and euthanized after blood was collected from the abdominal aorta. The rats were then dissected, and the size of the cysts was measured. The expression levels of VEGF and CA125 and the insulin resistance index in the serum were also detected.

[0088] Comparative Example 6

[0089] The difference between this comparative example and Example 5 is that the drug used in this comparative example is leuprolide acetate.

[0090] Table 4. Indicators of a rat model of chocolate cysts with insulin resistance

[0091]

[0092] Note: Compared with the control group of chocolate cyst model, * indicates P<0.05, and ** indicates P<0.01.

[0093] As shown in Table 4, compared with the blank control group, the cyst volume of rats in the model control group was significantly increased, and the serum VEGF and CA125 levels and insulin resistance index were significantly increased, indicating that the chocolate cyst model with insulin resistance was successfully established. After drug intervention (Example 8 and Comparative Example 6), the cyst volume, serum VEGF and CA125 levels, and insulin resistance index decreased to varying degrees. With the increase of the dosage of Dendrobium officinale plant preparation (Example 7), the cyst volume, serum VEGF and CA125 levels, and insulin resistance index all decreased accordingly, indicating that Dendrobium officinale plant preparation has a definite curative effect on chocolate cysts with insulin resistance.

[0094] Example 9

[0095] This embodiment describes the effect of the Dendrobium officinale plant preparation prepared in Example 1 on perimenopausal syndrome, including the following steps:

[0096] S1. After one week of acclimatization to 3-month-old SD animals, they were randomly divided into a blank control group (10 animals) and a model group (50 animals). The model group was anesthetized by intraperitoneal injection of 10% chloral hydrate 0.35 g / kg. The hair in the surgical area was clipped and disinfected with povidone-iodine. An incision was made 1-2 cm below the lower edge of the last rib on the back and 2 cm lateral to the spine on both sides. The ovary was located, and the tissue between the ovary and the uterus was ligated with surgical sutures. The ovary was removed. After checking for no active bleeding points, the tissue was sent into the abdominal cavity. The abdominal cavity was closed layer by layer. The wound was wiped with 0.9% saline to remove bloodstains. Vaginal smears were examined on the 5th day after surgery and continued for 5 days to determine whether the model was successful.

[0097] S2. Fifty successfully modeled rats were randomly divided into a model control group and an administration group. The administration group was given Dendrobium officinale plant preparation via intraperitoneal injection at doses of 20, 40, and 80 mg / kg, administered once every 24 hours for a total of 4 weeks. The blank control group and the model control group were given 10 mL / kg of physiological saline daily.

[0098] S3. Four weeks after administration to the group, the patients fasted for 12 hours, were anesthetized with 10% chloral hydrate, and blood was drawn from the abdominal aorta to measure the levels of testosterone, estradiol, luteinizing hormone, SOD, and IL-2.

[0099] Comparative Example 7
