Brief summary
Perimenopausal syndrome (PMS) is a common condition affecting women during the transition to menopause, often causing hot flashes, sweating, insomnia, anxiety, depression, fatigue, and reduced quality of life. Current hormone replacement therapy can improve symptoms, but long-term use may increase the risk of breast cancer and cardiovascular complications. Therefore, safer and more effective alternative treatments are needed. Jinfeng Pill is a traditional Chinese medicine patented drug that has been widely used in gynecological disorders. Previous studies suggest that it may help regulate hormone balance, improve ovarian function, and reduce inflammation. Recent research has also shown that intestinal bacteria ("gut microbiota") may influence estrogen metabolism through the "gut microbiota-estrogen axis," which could play an important role in perimenopausal symptoms. This study is a randomized, double-blind, placebo-controlled clinical trial designed to evaluate the effectiveness and safety of Jinfeng Pill in women with perimenopausal syndrome. Eligible participants will be randomly assigned to receive either Jinfeng Pill or a placebo for 12 weeks. Researchers will assess changes in menopausal symptoms, mood, sleep, and quality of life using standardized questionnaires and laboratory tests. In addition, the study will explore how Jinfeng Pill may regulate gut microbiota, β-glucuronidase (β-GUS) activity, short-chain fatty acids (SCFAs), inflammatory factors, and estrogen-related indicators. The findings may provide new evidence for the clinical use of traditional Chinese medicine in the treatment of perimenopausal syndrome and help clarify its underlying biological mechanisms.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| The modified Kupperman Index (KI) | Week -1, Week 0, Week 4, Week 8, Week 12, Week 16 | The total score of KI is 63. It includes 13 items related to peri-menopausal syndrome, and the severity score of each item ranges from 0 to 3. There were different basic score in each item: hot flashes and sweating = 4; Paresthesia, sleep disorders, nervousness, sexual complaints, urinary tract infection = 2; the other items = 1. Item score = basic score × severity score. Classification standard of disease condition: mild: symptom score \<13; moderate: symptom score 14-26; severe: symptom score \>27 points. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Hot flash scale (HFs) | Week -1, Week 0, Week 4, Week 8, Week 12, Week 16 | The severity of hot flash was evaluated using visual analog scale (0-10).The higher the value, the more severe the symptoms. |
| Menopause-specific quality of life scale (MENQOL) | Week 0, Week 12, Week 16 | MENQOL contains 27 questions related to vasomotor symptoms, psychological symptoms, physiological symptoms, and sexual life. A lower MENQOL score indicates PMPS has a less influence on life quality. |
| Hamilton depressive scale (HAMD) | Week 0, Week 12, Week 16 | The items of HAMD are scored on a 5-level scale with 0-4 points, a few items is a 3-level scale with 0-2 points. A higher score indicates the more severe depression. |
| Hamilton anxiety scale (HAMA) | Week 0, Week 12, Week 16 | HAMA contains 14 items related to a number of anxiety symptoms. Each of items is scored on a 5-level scale with 0-4 points. A higher score indicates the more severe anxiety. |
| Vaginal Health Index (VHI) | Week 0, Week 12 | The VHIS (Vaginal Health Index) comprises five assessment dimensions, each scored from 1 to 5 points, for a total of 25 points. A higher total score indicates better vaginal health, while a total score below 15 points suggests vaginal atrophy. |
| TCM Syndrome Score Scale | Week 0, Week 12 | Symptom severity will be graded according to the Guiding Principles for Clinical Research of New Chinese Medicines for eight TCM-specific symptom domains (hot flushes and sweating, menstrual irregularity, irritability, dizziness and headache, lumbar and knee soreness, insomnia with vivid dreaming, hypochondriac pain with bitter taste, and vaginal dryness), each rated 0-3 (absent/mild/moderate/severe). The total score is 24 points, with higher scores indicating more severe symptoms. |
| Serum levels of sex hormones (E2, FSH, LH) and estrogen metabolites (2-OHE1,16α-OHE1) | Week 0, Week 12 | Serum E2, FSH, and LH will be quantified by enzyme-linked immunosorbent assay (ELISA). Estrogen metabolites - 2-hydroxyestrone (2-OHE1) and 16α-hydroxyestrone (16α-OHE1) - will be determined by liquid chromatography-mass spectrometry (LC-MS). |
| Serum inflammatory factors (IL-6, TNF-α) | Week 0, Week 12 | Serum concentrations of interleukin-6 (IL-6) and tumour necrosis factor-alpha (TNF-α) will be measured by ELISA |
| Intestinal microbiota β-GUS enzyme activity | Week 0, Week 12 | β-GUS activity will be determined spectrophotometrically via the enzymatic hydrolysis of p-nitrophenyl-β-D-glucuronide (pNPG) to p-nitrophenol (pNP), quantified by absorbance at 405 nm. |
| Short-Chain Fatty Acids (SCFAs) | Week 0, Week 12 | Faecal concentrations of acetic acid, propionic acid, and butyric acid will be determined by gas chromatography. |
| Gut Microbiota Analysis | Week 0, Week 12 | Faecal samples will be collected at baseline and week 12. Participants will provide ≥5 mg of stool into a sterile collection tube, which will be immediately snap-frozen in liquid nitrogen and stored at -80°C pending analysis. Bacterial genomic DNA will be extracted using the QIAamp Swab DNA Kit (QIAGEN). The V3-V4 hypervariable regions of the 16S rRNA gene will be amplified by PCR and sequenced on the Illumina NextSeq 2000 platform. |
