QXZS in Menopausal Syndrome Based on 16S rRNA Sequencing Technology

Study on the (Heart) Brain-gut Axis Mechanism of Qingxin Zishen Decoction in Treating Hot Flashes in Menopausal Syndrome Based on 16S rRNA Sequencing Technology

The goal of this clinical trial is to explore the differences of intestinal flora and saliva flora between menopausal women, and the changes after medication, to find the association between the two and menopausal syndrome. The main questions it aims to answer are:

• What are the differences in intestinal flora and saliva flora in menopausal women with hot flashes and sweating.

• Whether these differences change after using traditional Chinese medicine and the association between intestinal, salivary flora and menopausal syndrome.

  60 patients will be screened according to the clinical experimental criteria. They will be randomly divided into trial group (30 cases) and control group (30 cases). The test group takes traditional Chinese medicine Qingxin Zishen decoction, and the control group takes oral Femoston, comparing the two groups with analysis of symptom improvement, intestinal flora and salivary flora with 16S rRNA sequencing technology.

Inclusion Criteria:

• Those who meet the diagnostic criteria for menopausal syndrome and the TCM heart and kidney syndrome differentiation criteria.
• Women between the ages of 45~55.
• The score of the modified Kupperman Menopausal Symptom Rating Scale ≥ 15 points.
• Hot flashes and sweating≥ 3 times/day.
• Menopause ≥ 6 months.
• FSH > 10U/L during menopausal transition, 40U/L > after menopause, and estradiol (E2) < (10~20) pg/mL.

Exclusion Criteria:

• Other Chinese and Western drugs for the treatment of menopausal syndrome have been used after the onset of the disease.
• Have serious primary heart, liver, lung, kidney, blood or serious diseases that affect their survival.
• Contraindications to hormone therapy: known or suspected pregnancy; In perimenopausal women, menstrual disorders should be ruled out to exclude pregnancy-related problems such as intrauterine pregnancy, ectopic pregnancy, and trophoblastic disease. Unexplained vaginal bleeding: Causes of vaginal bleeding include neoplastic, inflammatory, iatrogenic, traumatic, and ovarian dysfunction, which should be carefully identified before perimenopausal menstrual disorders are treated with sex hormones.

Severe hepatic and renal insufficiency.
