RESUMEN

ETHNOPHARMACOLOGICAL RELEVANCE: The herbal formula Guizhi Fuling Wan is one common remedy for treating uterine fibroids (UFs) and the relevant symptoms in Traditional Chinese Medicine (TCM). Previous systematic reviews showed that Guizhi Fuling Formula appeared to have additional benefit based on mifepristone treatment in reducing volume of fibroids. AIM OF STUDY: To study the efficacy and safety of the conventional dose of a modified herbal formula Guizhi Fuling Wan in patients with symptomatic uterine fibroids in comparison with a sub-effective dose control. MATERIALS AND METHODS: This randomized double-blind, dosage-controlled trial was carried out in an outpatient clinic of traditional Chinese medicine in Hong Kong. Women with symptomatic uterine fibroids diagnosed according to the WHO International Classification of Diseases (ICD-10) were recruited and randomly assigned to one of two groups that received modified Guizhi Fuling Wan at either a low dose or the conventional dose on a daily basis for 16 weeks. This study was quality controlled by a data safety monitoring board. The primary outcome was the symptom severity as measured with the Uterine Fibroid Symptom-Quality of Life questionnaire. The secondary outcomes included quality of life, menstrual bleeding (measured on a pictorial blood loss assessment chart), pain severity (measured on the 6-point behavioral rating scale), change in Chinese medicine syndrome score, fibroid volume (measured by magnetic resonance imaging), hemoglobin level, and hormone levels. RESULTS: Seventy-eight women were recruited for this study. Between-groups comparison showed no significant difference at the endpoint for all outcomes except for the Chinese medicine syndrome score; however, at the endpoint, within-group comparison showed significant improvement in both groups relative to baseline in symptom severity, functional influence of pelvic pain, Chinese medicine syndrome score, and fibroid volume and uterus condition on magnetic resonance imaging (p < 0.05).The low-dose group yielded greater endpoint improvement in the Chinese medicine syndrome score than the conventional-dose group (p=0.024). No serious adverse events related to the intervention were noted. CONCLUSION: Both low-dose and conventional-dose preparations significantly ameliorated uterine fibroid-related symptoms and fibroid volume, although no significant difference was found between the low-dose and conventional-dose groups. The herbal formula GuizhiFuling Wan is safe in women with uterine fibroids.

RESUMEN

BACKGROUND: Acupuncture reduces pain levels in many painful conditions. This study compared pain levels during surgical termination of first trimester pregnancy by suction evacuation (SE) under local analgesia with and without the use of acupuncture. METHODS: In all, 60 nulliparous women undergoing SE before 10 weeks of gestation were randomly assigned into one of the following three groups in a 1:1:1 ratio according to a computer-generated randomization list. In the control group, women received oral diazepam 5 mg and intramuscular (i.m.) injection of pethidine 30 and 15 min, respectively, prior to SE. In the acupuncture group, women received acupuncture 10 min before SE until the end of SE while oral diazepam 5 mg and i.m. injection of normal saline were given. In the combined group, women received acupuncture in addition to the drugs in the control group. Data from 52 participants were analysed. Pain scores during and after SE, post-operative side-effects and satisfaction levels were compared. RESULTS: The three groups had similar baseline characteristics. The median pain levels during SE differed significantly between the control, acupuncture, and combined groups (80, 50 and 66 mm, respectively, p = 0.03). Pain levels during SE in the acupuncture and combined groups were significantly lower than that of the control group. However, the anxiety scores did not differ between the three groups after SE (p = 0.86). CONCLUSION: Acupuncture can provide additional benefit in terms of pain relief in women undergoing first trimester termination of pregnancy by SE under local analgesia.

RESUMEN

OBJECTIVE: To test the hypothesis that acupuncture improves insulin sensitivity in women with polycystic ovary syndrome (PCOS) and insulin resistance (IR). DESIGN: Prospective pilot study. SETTING: Guangzhou, China, 2014-2016. PARTICIPANTS: Eighty women with PCOS aged 18-40 years with body mass index (BMI) above 18.5 kg/m2 and with homeostatic model assessment for insulin resistance (HOMA-IR) index ⩾2.14. INTERVENTIONS: Subjects received acupuncture with combined manual and low-frequency electrical stimulation of the needles three times per week for 6 months. PRIMARY AND SECONDARY OUTCOME MEASURES: The primary outcome was the change in HOMA-IR after 6 months of acupuncture relative to baseline. Secondary outcomes included changes after 6 months of acupuncture and at 3 months of follow-up (both relative to baseline) in oral glucose tolerance test (OGTT) parameters (glucose and insulin levels), anthropometric measurements, and circulating metabolic and endocrine variables. RESULTS: HOMA-IR and fasting plasma glucose and insulin levels were significantly decreased after 6 months of acupuncture, and both HOMA-IR and fasting insulin remained significantly decreased at 3 months of follow-up. In a subgroup analysis of normal-weight and overweight/obese women, HOMA-IR was reduced after 6 months of acupuncture in both subgroups, but there was no significant difference between the two groups. CONCLUSIONS: Acupuncture treatment in Chinese women with PCOS and IR was associated with an encouraging improvement in insulin sensitivity. Further randomized controlled studies are required to confirm the efficacy of acupuncture for this indication.

RESUMEN

BACKGROUND: Traditional Chinese medicine (TCM) usually involves syndrome differentiation and treatment. Acupuncture, one form of TCM, requires the selection of appropriate acupoints and needling techniques, but many clinical trials on acupuncture have used fixed acupuncture protocols without accounting for individual patient differences. We have designed a multicenter randomized controlled trial (RCT) to evaluate whether personalized or fixed acupuncture increases the likelihood of live births in infertile women with polycystic ovary syndrome (PCOS) compared with letrozole or placebo letrozole. We hypothesize that letrozole is more effective than personalized acupuncture, which in turn is more effective than fixed acupuncture, and that placebo letrozole is the least effective intervention. Moreover, we hypothesize that personalized acupuncture is more likely to reduce the miscarriage rate and the risk of pregnancy complications compared with letrozole. METHODS/DESIGN: The study is designed as an assessor-blinded RCT. A total of 1100 infertile women with PCOS will be recruited from 28 hospitals and randomly allocated to 4 groups: personalized acupuncture, fixed acupuncture, letrozole, or placebo letrozole. They will receive treatment for 16 weeks, and the primary outcome is live birth. Secondary outcomes include ovulation rate, conception rate, pregnancy rate, pregnancy loss rate, changes in hormonal and metabolic parameters, and changes in quality of life scores. Adverse events will be recorded throughout the trial. All statistical analyses will be performed using IBM SPSS Statistics version 21.0 software (IBM Corp., Armonk, NY, USA), and a P value < 0.05 will be considered statistically significant. DISCUSSION: This study will be the first multicenter RCT to compare the effect of personalized or fixed acupuncture with letrozole or placebo letrozole on live birth in infertile women with PCOS. The findings will inform whether personalized acupuncture therapy can be considered an alternative treatment to improve the live birth rate in infertile women with PCOS.

RESUMEN

BACKGROUND: Transvaginal oocytes retrieval is an essential step in in-vitro fertilization treatment. There are different pain relief methods, but none has been shown to be superior than the others. Transcutaneous electrical nerve stimulation (TENS) is a non-pharmacological and non-invasive pain relief method. This study aims to compare the pain levels experienced by the women using the conscious sedation and those who had TENS in addition to conscious sedation. METHODS AND ANALYSIS: This is a double-blinded randomized trial that will be carried out in a university-assisted conception unit. Women who will undergo oocyte retrieval under conscious sedation will be recruited. After randomization, women will be allocated to either the active TENS group or placebo TENS group (the TENS machine will not emit active impulse), in addition to the paracervical block and conscious sedation. The primary outcome is pain levels of women during the retrieval assessed by the visual analog scale. Secondary outcomes include satisfaction of women and postoperative side effects. DISCUSSION: TENS is an effective non-pharmacological and non-invasive method for pain relief in a number of clinical conditions. Both women and assisted conception unit can benefit if the addition of non-invasive, simple, and low-cost TENS application is proven to be superior than using conscious sedation and paracervical block alone.

RESUMEN

INTRODUCTION: The Chinese medicine formulation, tumour-shrinking decoction (TSD, FM1523), which consists of 15 natural medicines, is used for uterine fibroids (UFs) therapy and possesses excellent clinical therapeutic effect. OBJECTIVE: To develop a sensitive and validated analytical method for the simultaneous quantification of four crucial bioactive compounds including isorhamnetin-3-O-neohesperidoside, curcumin, peimine and tetrahydropalmatine in the principal formulation of this decoction. METHODS: An ultra-performance liquid chromatography coupled tandem mass spectrometry (UPLC-MS/MS) with an electrospray ionisation (ESI) source in multiple reaction monitoring (MRM) mode was conducted to investigate these bioactive compounds in the TSD. The chromatographic separation was performed on a C18 column when the flow rate was adjusted at 0.2 mL/min with gradient elution of acetonitrile-water with 0.1% formic acid. Accelerated solvent extraction (ASE) method with higher extraction efficiency was employed for TSD sample pre-treatment. RESULTS: The linearity, limit of detection (LOD) and limit of quantification (LOQ) were determined for this analytical method. The mean recoveries of the compounds were determined between 100.23% and 104.02% with satisfactory relative standard deviation (RSD) in the ranges of 2.65% to 3.81%. The precision was evaluated by intra-day and inter-day tests, which revealed RSD within the ranges of 1.21% to 2.14% and 1.24% to 2.32%, respectively. CONCLUSION: The bioactive compounds of TSD samples were successfully quantified via UPLC-MS/MS with MRM mode. This study could help to evaluate the pharmacokinetic study of TSD during clinical applications and present a facile strategy for quantifying bioactive compounds in traditional Chinese Medicine decoction.

RESUMEN

PURPOSE: To evaluate the effect of 12-month DHEA supplementation on menstrual pattern and ovarian reserve markers in women with premature ovarian insufficiency (POI) METHODS: This is a prospective observational study. Women with POI were given DHEA supplements (25 mg three times daily) for 12 months. Sonographic assessment for ovarian volume and antral follicle count (AFC) and serum measurement for anti-Mullerian hormone (AMH), follicle stimulating hormone (FSH), estradiol, testosterone, liver function, and hemoglobin level were performed at baseline and monthly for 13 months after the supplementation. Menstrual pattern, ovarian reserve markers, and side-effects were recorded. RESULTS: Between August 2011 and July 2014, 38 women with POI were recruited and 31 completed the study. The median age of women was 36 years, and the median baseline FSH and AMH concentrations were 82.2 IU/L and 0.01 ng/ml, respectively. No women had resumption of regular menstruation after DHEA supplementation. AMH, FSH, and AFC did not change significantly. No serious side effects were reported. CONCLUSIONS: Our results do not support any significant improvement in ovarian function by 12-month DHEA supplementation in women with POI.

RESUMEN

BACKGROUND: Our prospective pilot study of acupuncture affecting insulin sensitivity on polycystic ovary syndrome (PCOS) combined with insulin resistance (IR) showed that acupuncture had a significant effect on improving the insulin sensitivity of PCOS. But there is still no randomized controlled trial to determine the effect of acupuncture on the insulin sensitivity in women with PCOS and IR. In this article, we present the protocol of a randomized controlled trial to compare the effect of true acupuncture on the insulin sensitivity of these patients compared with metformin and sham acupuncture. Acupuncture may be an effective therapeutic alternative that is superior to metformin and sham acupuncture in improving the insulin sensitivity of PCOS combined with IR. METHODS: This study is a multi-center, controlled, double-blind, and randomized clinical trial aiming to evaluate the effect of acupuncture on the insulin sensitivity in PCOS combined with IR. In total 342 patients diagnosed with PCOS and IR will be enrolled. Participants will be randomized to one of the three groups: (1) true acupuncture + metformin placebo; (2) sham acupuncture + metformin, and (3) sham acupuncture + metformin placebo. Participants and assessors will be blinded. The acupuncture intervention will be given 3 days per week for a total of 48 treatment sessions during 4 months. Metformin (0.5 g per pill) or placebo will be given, three times per day, and for 4 months. Primary outcome measures are changes in homeostasis model assessment of insulin resistance (HOMA-IR) and improvement rate of HOMA-IR by oral glucose tolerance test (OGTT) and insulin releasing test (Ins). Secondary outcome measures are homeostasis model assessment-ß (HOMA-ß), area under the curve for glucose and insulin, frequency of regular menstrual cycles and ovulation, body composition, metabolic profile, hormonal profile, questionnaires, side effect profile, and expectation and credibility of treatment. Outcome measures are collected at baseline, at the end of treatments, and 3 months after the last acupuncture treatment. On completion of the screening visit, randomization will be conducted using a central randomization system. DISCUSSION: This study will investigate the effects of acupuncture on the insulin sensitivity of PCOS and IR women compared with metformin and sham acupuncture. We will test whether true acupuncture with needles placed in skeletal muscles and stimulated manually and by electrical stimulation is more effective than metformin and sham acupuncture with superficial needle placement with no manual or electrical stimulation in improving the insulin sensitivity in PCOS women with IR.

RESUMEN

INTRODUCTION: The high prevalence of insulin resistance in women with polycystic ovary syndrome (PCOS) is considered to be one of the major pathophysiological changes in PCOS that leads to anovulatory infertility. We hypothesise that electroacupuncture pretreatment improves insulin sensitivity and leads to a higher ovulation rate and greater chances of live birth after the induction of ovulation. The effect of electroacupuncture pretreatment followed by ovulation induction in women with anovulatory PCOS has not been investigated before, and we present here a randomised controlled trial to test this hypothesis by comparing electroacupuncture pretreatment followed by letrozole versus letrozole alone in anovulatory women with PCOS. METHODS/ANALYSIS: This is a multicentre, randomised,and controlled trial. A total of 384 patients will be enrolled in this study and will be randomly allocated by a central randomisation system to the treatment group or the control group in a 1:1 ratio. The treatment group will undergo 16 weeks of electroacupuncture pretreatment followed by 4 cycles of letrozole, and the control group will only undergo 4 cycles of letrozole. The primary outcome will be the live birth rate. All statistical analyses will be performed using the SPSS program V.21.0 (SPSS, Chicago, Illinois, USA), and a p value <0.05 will be considered statistically significant. ETHICS/DISSEMINATION: This study has been approved by the ethics committees of each participating centre. Written consent will be obtained from each patient and her husband before any study procedure is performed. Adverse events will be categorised, and the percentage of patients experiencing adverse events or serious adverse events during the treatment period will be documented. The results of this trial will be disseminated in peer-reviewed journals and presented at international meetings. TRIAL REGISTRATION NUMBER: NCT02491320.

RESUMEN

OBJECTIVE: To evaluate whether pretreatment dehydroepiandrosterone (DHEA) supplementation improves ovarian response markers, ovarian response to standard low-dose gonadotropin stimulation, and in vitro fertilization (IVF) outcomes in poor responders. DESIGN: Randomized, double-blind, placebo-controlled pilot study. SETTING: Tertiary reproductive medicine unit. PATIENT(S): Thirty-two women with anticipated poor ovarian response. INTERVENTION(S): Randomization into DHEA group (n=16) receiving GNC (25 mg three times a day) or placebo (n=16) starting from at least 12 weeks before the scheduled IVF treatment according to a computer-generated randomization list. MAIN OUTCOME MEASURE(S): Measurement of monthly ovarian response markers, including antral follicle count (AFC), serum antimüllerian hormone (AMH), and follicle-stimulating hormone (FSH) levels; comparison of ovarian response to a standard dose of gonadotropin stimulation at week 8 and IVF outcomes; and AFC after 12 weeks (primary outcome). RESULT(S): The DHEA supplementation resulted in statistically significantly higher serum DHEA-S, free androgen index, and follicular DHEA-S levels. No statistically significant differences in the ovarian response markers (AFC, AMH, or FSH), the ovarian response to standard-dose gonadotropin stimulation, or IVF outcomes were found between the two groups. CONCLUSION(S): No statistically significant improvement in ovarian response markers, ovarian response to standard dose gonadotropin stimulation, or IVF outcomes was found in poor responders receiving pretreatment DHEA.

RESUMEN

Acupuncture is an alternative therapy to induce ovulation in women with polycystic ovary syndrome (PCOS), but there is no study reporting the live birth rate following ovulation induction by acupuncture or its potential as an adjuvant treatment to clomiphene citrate (CC). We assess the efficacy of acupuncture with or without CC in achieving live births among 1000 PCOS women in Mainland China. This paper reports the methodology of an ongoing multicenter randomized controlled trial. The randomization scheme is coordinated through the central mechanism and stratified by the participating sites. Participants will be randomized into one of the four treatment arms: (A) true acupuncture and CC, (B) control acupuncture and CC, (C) true acupuncture and placebo CC, and (D) control acupuncture and placebo CC. To ensure the quality and integrity of the trial we have developed a unique multinational team of investigators and Data and Safety Monitoring Board. Up to the end of April 2013, 326 subjects were recruited. In conclusion, the success of this trial will allow us to evaluate the additional benefit of acupuncture beyond the first line medicine for fertility treatment in PCOS women in an unbiased manner.

RESUMEN

BACKGROUND: Insulin resistance and hyperinsulinemia play a key role in the pathogenesis of polycystic ovary syndrome (PCOS), which is characterized by hyperandrogenism, ovulatory dysfunction, and presence of polycystic ovaries on pelvic scanning. Insulin resistance is significantly associated with the long-term risks of metabolic syndrome and cardiovascular disease. Berberine has effects on insulin resistance but its use in women with PCOS has not been fully investigated. In this paper, we present a research design evaluating the effects of berberine on insulin resistance in women with PCOS. METHODS/DESIGN: This is a multicenter, randomized, placebo-controlled and double-blind trial. A total of 120 patients will be enrolled in this study and will be randomized into two groups. Berberine or placebo will be taken orally for 12 weeks. The primary outcome is the whole body insulin action assessed with the hyperinsulinemic-euglycemic clamp. DISCUSSION: We postulate that women with PCOS will have improved insulin resistance following berberine administration. TRIAL REGISTRATION: This study is registered at ClinicalTrials.gov, NCT01138930.

RESUMEN

As an integral part of traditional Chinese medicine (TCM), acupuncture is a convenient and effective therapy with fewer adverse effects. Recently, researches on meridian essence have become core issues of modern TCM. Numerous experiments have demonstrated the objective existence of meridians by different technologies since 1950s, such as biophysics, biochemistry, and molecular biology. In this paper, we review biophysical studies on electric, acoustic, thermal, optical, magnetic, isotopic, and myoelectric aspects of meridians and acupoints. These studies suggest that meridians/acupoints have biophysical characteristics which are different from nonacupuncture points. Owing to the limitations of previous studies, future research using high-throughput technologies such as omics and multicenter randomized controlled trials should be performed to explore the acupuncture's mechanisms of action and demonstration of efficacy.

RESUMEN

Acupuncture is increasingly being used in reproductive medicine. This review summarizes the evidence of acupuncture in pain relief for oocyte retrieval, improving pregnancy outcomes of in vitro fertilization treatment, management of ovulation disorders, male subfertility, primary dysmenorrhea, endometriosis and menopausal symptoms. However, most of the studies are nonrandomized uncontrolled trials, case reports or case series. For randomized controlled trials, the sample size is underpowered and blinding of assessors is lacking. Different acupuncture protocols and controls are used. These heterogeneities make it difficult to compare studies and draw any firm conclusions. Further studies should also evaluate the cost-effectiveness of acupuncture and investigate the underlying mechanism of acupuncture treatment.

RESUMEN

The role of acupuncture on the pregnancy rate has not been evaluated in frozen-thawed embryo transfer (FET) cycles. This randomized double-blind study aimed to determine whether acupuncture performed on the day of FET improves clinical outcomes. On the day of FET, 226 patients were randomly allocated to either real or placebo acupuncture according to a computer-generated randomization list in sealed opaque envelopes. They received a session of real or placebo acupuncture for 25 min on site immediately after FET. The anxiety level and serum cortisol concentration were evaluated before and after real and placebo acupuncture. There were no significant differences in rates of overall pregnancy, clinical pregnancy, ongoing pregnancy, live birth and implantation in the placebo acupuncture group, when compared with the real acupuncture group. The anxiety level and serum cortisol concentration were similar for both groups. Only the placebo acupuncture group had significantly higher ongoing pregnancy (P=0.022) and implantation rates (P=0.038) than those who declined to join the study and received no acupuncture. In conclusion, comparable pregnancy and live birth rates of FET treatment were found in patients who had one session of real or placebo acupuncture after FET.

RESUMEN

BACKGROUND: Acupuncture has been used during IVF treatment as it may improve outcome, however, there are concerns about the true efficacy of this approach. This randomized double blind study aimed to compare real acupuncture with placebo acupuncture in patients undergoing IVF treatment. METHODS: On the day of embryo transfer (ET), 370 patients were randomly allocated to either real or placebo acupuncture according to a computer-generated randomization list in sealed opaque envelopes. They received 25 min of real or placebo acupuncture before and after ET. The endometrial and subendometrial vascularity, serum cortisol concentration and the anxiety level were evaluated before and after real and placebo acupuncture. RESULTS: The overall pregnancy rate was significantly higher in the placebo acupuncture group than that in the real acupuncture group (55.1 versus 43.8%, respectively, P = 0.038; Common odds ratio 1.578 95% confidence interval 1.047-2.378). No significant differences were found in rates of ongoing pregnancy and live birth between the two groups. Reduction of endometrial and subendometrial vascularity, serum cortisol concentration and the anxiety level were observed following both real and placebo acupuncture, although there were no significant differences in the changes in all these indices between the two groups. CONCLUSIONS: Placebo acupuncture was associated with a significantly higher overall pregnancy rate when compared with real acupuncture. Placebo acupuncture may not be inert.

RESUMEN

OBJECTIVE: To review systematically the use of acupuncture in the management of subfertility. DESIGN: A computer search was performed via several English and Chinese databases to identify journals relevant to the subject. RESULT(S): The positive effect of acupuncture in the treatment of subfertility may be related to the central sympathetic inhibition by the endorphin system, the change in uterine blood flow and motility, and stress reduction. Acupuncture may help restore ovulation in patients with polycystic ovary syndrome, although there are not enough randomized studies to validate this. There is also no sufficient evidence supporting the role of acupuncture in male subfertility, as most of the studies are uncontrolled case reports or case series in which the sample sizes were small. Despite these deficiencies, acupuncture can be considered as an effective alternative for pain relief during oocyte retrieval in patients who cannot tolerate side effects of conscious sedation. The pregnancy rate of IVF treatment is significantly increased, especially when acupuncture is administered on the day of embryo transfer. CONCLUSION(S): Although acupuncture has gained increasing popularity in the management of subfertility, its effectiveness has remained controversial.
