Efficacy and Safety of Ganyushu Granule in Treatment of Premenstrual Syndrome with Gan (Liver) Depression and Qi Stagnation Syndrome: A Randomized, Double-Blind, Multi-Center, Phase-II Clinical Trial.

OBJECTIVE: To confirm the efficacy and safety of Ganyushu Granule (GYSG) in treating premenstrual syndrome (PMS) in patients with Gan (Liver) depression and qi stagnation syndrome (GDQSS) and determine its effective dosage. METHODS: From June 2018 to March 2021, a total of 240 PMS women with GDQSS were included and randomly divided into 3 groups in a 1:1:1 ratio using central block randomization: high-dose GYSG group (n=78, GYSG 2 packs/time), low-dose GYSG group (n=82, GYSG and its simulant 1 pack/time), and placebo group (n=80, GYSG simulant 2 packs/time). Treatment with GYSG or placebo was given thrice daily and for up to 3 menstrual cycles. Primary outcomes were PMS diary (PMSD) score and premenstrual tension syndrome self-rating scale (PMTS). Secondary outcomes were Chinese medicine (CM) syndrome efficacy. PMSD, PMTS, and efficacy of CM were evaluated with menstrual cycles during the treatment period. Outcome indicators were analyzed after each menstrual cycle. All analyses were performed using an intention-to-treat method, and clinical safety was assessed. RESULTS: Of the 216 patients included in the effectiveness analysis, 70, 75, and 71 patients were in the high-, low-dose GYSG, and placebo groups, respectively. From the 2nd treatment cycle, the change in PMSD scores in the high- and low-dose groups was lower than that in the placebo group (P<0.05). PMTS scores in the high-dose GYSG group after the 1st treatment cycle was lower than that in the placebo group (P<0.05), while after the 3rd treatment cycle, that in the low-dose group was lower than that in the placebo group (P<0.05). After the 2nd treatment cycle, the high-dose GYSG group had the best CM syndrome efficacy (P<0.05). No serious adverse reactions were reported. CONCLUSIONS: GYSG was safe and well-tolerated at both doses for treating PMS patients with GDQSS. High-dose GYSG might be the optimal dose for a phase III trial. (Registration No. ChiCTR1800016595).

[Effects of electroacupuncture on pregnancy outcome in poor ovarian response patients of kidney essence deficiency and undergoing in vitro fertilization-embryo transfer].

OBJECTIVE: To observe the effects of electroacupuncture (EA) on ovarian reaction, egg and embryo quality, as well as pregnancy rate in poor ovarian response (POR) patients of kidney essence deficiency and undergoing in vitro fertilization-embryo transfer (IVF-ET). METHODS: Ninety-six patients who met the inclusion criteria were randomly divided into an EA group and a control group, with 48 cases in each group. Before IVF-ET, the patients in the EA group received EA, once daily, 2 or 3 treatments a week for 12 weeks. Before and after the treatment, traditional Chinese medicine (TCM) syndrome score and clinical pregnancy rate were assessed in two groups. The concentrations of serum follicle-stimulating hormone (FSH), luteinsing hormone, estradiol, progesterone and anti-mullerian hormone were detected by chemiluminescence; the contents of serum insulin-like growth factor-1, serum inhibin B (INHB) and Kisspeptin in follicular fluid were determined by enzyme linked immunosorbent assay (ELISA); the antral follicle counting (AFC) was detected by color Doppler ultrasonography; and the egg and embryo conditions were observed under microscope. Fourteen days after embryo transfer, the positive rate of serum hemchoriconic gonadotropin (HCG) and clinical pregnancy rate were calculated. RESULTS: After the treatment, the TCM syndrome score and level of serum FSH were reduced (P<0.05); the INHB in serum and AFC were increased (P<0.05) when compared with those before the treatment in the EA group. After the treatment, in comparison with the control group, the TCM syndrome score and level of serum FSH were lower (P<0.05); and the contents of serum INHB, AFC, the numbers of MⅡ eggs and high-quality embryos, as well as serum HCG positive rate were all increased (P<0.05) in the EA group. CONCLUSION: EA can relieve the clinical symptoms of TCM in POR patients of kidney essence deficiency and undergoing IVF-ET, increase the ovarian reserve, reduce the serum FSH level, and improve the content of serum INHB, and the quality of eggs and embryos. This therapy tends to improve the clinical pregnancy rate and clinical pregnancy outcome.

Simultaneous bilateral fallopian tubal pregnancy of a laparoscopic definite spontaneous unilateral ovulation: a case report.

BACKGROUND: Bilateral simultaneous fallopian tubal pregnancy is one of the rarest forms of ectopic pregnancy. Due to the lack of unique features and clinical presentation to distinguish bilateral from unilateral ectopic pregnancy, challenges the diagnosis. CASE REPORT: A 27-year-old Asian woman presented with pelvic pain and vaginal bleeding. Pelvic transvaginal ultrasound showed fluid in Douglas Pouch and posterior fornix puncture revealed unclotted blood. Laparoscopic examination unveiled bilateral ectopic pregnancy with two corpus luteum visible in the right ovary, suggesting a double spontaneous unilateral ovulation. Bilateral fallopian tube fenestration and embryo extraction were performed to preserve fertility. CONCLUSION: Diagnosis of bilateral tubal pregnancy is difficult during preoperative ultrasound examination and careful examination during laparoscopic inspection of the whole pelvic cavity to avoid missed diagnosis.

Efficacy and side-effects of a semi-individualized Chinese herb mixture "Tiáo Geng Tang" for menopausal syndrome in China.

BACKGROUND: Chinese herbal medicine is an alternative therapy for menopausal problems and is widely practiced in China and many other Asian countries. However, efficacies and side-effects are rarely assessed according to the standards of evidence-based medicine. PATIENTS AND METHODS: This is a prospective observatory study following efficacy and side-effects of a semi-individualized Chinese herbal mixture "Tiáo Geng Tang (TGT)" in 30 patients for 3 months. Another group of 30 patients receiving hormone therapy with tibolone was included as a positive comparison. Common questionnaire-based measuring instruments were: modified Kupperman index, menopause rating scale, life quality and Chinese medical symptom scale (CMSS). Follicle-stimulating hormone (FSH), luteinizing hormone (LH) and estradiol (E2) were determined before and three months after the treatments. RESULTS: Significant improvement was seen in overall scores of all the four measurements in both groups. For some symptoms, including dry mouth, tinnitus, poor appetite and constipation, TGT was more effective than tibolone. For psychosocial and sexual sub-scales of life quality, tibolone has a slightly higher remedy rate than TGT. TGT lowered FSH and LH significantly, as tibolone did, but elevated E2 significantly less than tibolone. Various adverse events, including body weight increase, abdomen discomfort, nausea/vomiting, emotional instability, pressure in breasts and dizziness, were reported by patients treated with tibolone, whereas only diarrhea was observed in two patients treated with TGT. CONCLUSION: TGT alleviates menopausal symptoms with similar efficacy as tibolone but has fewer side effects.

Efficacy and side effects of chinese herbal medicine for menopausal symptoms: a critical review.

This study evaluates 23 (9 Chinese and 14 non-Chinese) randomized controlled trials for efficacy and side effects of Chinese herbal medicine on menopausal symptoms. Menopause was diagnosed according to western medicine criteria in all studies while seven Chinese studies and one non-Chinese study further stratified the participants using traditional Chinese medical diagnosis "Zheng differentiation." Efficacy was reported by all 9 Chinese and 9/14 non-Chinese papers. Side effects and adverse events were generally mild and infrequent. Only ten severe adverse events were reported, two with possible association with the therapy. CHM did not increase the endometrial thickness, a common side effect of hormone therapy. None of the studies investigated long-term side effects. Critical analysis revealed that (1) high-quality studies on efficacy of Chinese herbal medicine for menopausal syndrome are rare and have the drawback of lacking traditional Chinese medicine diagnosis (Zheng-differentiation). (2) Chinese herbal medicine may be effective for at least some menopausal symptoms while side effects are likely less than hormone therapy. (3) All these findings need to be confirmed in further well-designed comprehensive studies meeting the standard of evidence-based medicine and including Zheng-differentiation of traditional Chinese medicine.

Chinese herb mix Tiáo-Geng-Tang possesses antiaging and antioxidative effects and upregulates expression of estrogen receptors alpha and beta in ovariectomized rats.

BACKGROUND: Herb mixtures are widely used as an alternative to hormonal therapy in China for treatment of the menopausal syndrome. However, composition of these herb mixtures are complex and their working mechanism is often unknown. This study investigated the effect of Tiáo-Geng-Tang (TG-decoction), a Chinese herbal mixture extract, in balancing female hormones, regulating expression of estrogen receptors (ERs), and preventing aging-related tissue damage. METHODS: Ovariectomized 5-month-old female rats were used to model menopause and treated with either TG-decoction or conjugated estrogen for 8 weeks. Estradiol (E2), luteinizing hormone (LH) and follicle-stimulating hormone (FSH) were measured in serum and in the hypothalamus. Hypothalamic expression of estrogen receptor (ER) alpha and beta were studied by real-time PCR and western blotting. Total antioxidant capacity (T-AOC), oxidation indicator superoxide dismutase (SOD) activity and tissue damage parameter malondialdehyde (MDA) were measured using standard assays. Aging-related ultrastructural alterations in mitochondria were studied in all animals by transmission electron microscopy. RESULTS: TG-decoction-treatment elevated E2 and lowered FSH in serum of ovariectomized rats. The potency and efficacy of TG-decoction on the hypothalamus was generally weaker than that of conjugated estrogens. However, TG-decoction was superior in upregulating expression of ERα and ß. TG-decoction increased hypothalamic SOD and T-AOC levels and decreased MDAlevels and mitochondrial damage in hypothalamic neurons. CONCLUSIONS: TG-decoction balances female hormones similarly to conjugated estrogens but less effectively. However, it is superior in up regulating ERα and ß and exhibits antioxidative antiaging activities. Whilst it shares similar effects with estrogen, TG-decoction also seems to have distinctive and more complex functions and activities.
