Effects of the kampo formula tokishakuyakusan on headaches and concomitant depression in middle-aged women

Mathematical algorithm–based identification of the functional components and mechanisms in depression treatment: An example of Danggui-Shaoyao-San

Depression, a complex epidemiological mental disorder, affects around 350 million people worldwide. Despite the availability of antidepressants based on monoamine hypothesis of depression, most patients suffer side effects from these drugs, including psychomotor impairment and dependence liability. Traditional Chinese medicine (TCM) is receiving more and more attention due to the advantages of high therapeutic performance and few side effects in depression treatment. However, complex multicomponents and multi-targets in TCM hinder our ability to identify the functional components and molecular mechanisms of its efficacy. In this study, we designed a novel strategy to capture the functional components and mechanisms of TCM based on a mathematical algorithm. To establish proof of principle, the TCM formula Danggui-Shaoyao-San (DSS), which possesses remarkable antidepressant effect but its functional components and mechanisms are unclear, is used as an example. According to the network motif detection algorithm, key core function motifs (CIM) of DSS in treating depression were captured, followed by a functional analysis and verification. The results demonstrated that 198 pathways were enriched by the target genes of the CIM, and 179 coincided with the enriched pathways of pathogenic genes, accounting for 90.40% of the gene enrichment pathway of the C-T network. Then the functional components group (FCG) comprising 40 components was traced from CIM based on the target coverage accumulation algorithm, after which the pathways enriched by the target genes of FCG were selected to elucidate the potential mechanisms of DSS in treating depression. Finally, the pivotal components in FCG of DSS and the related pathways were selected for experimental validation in vitro and in vivo. Our results indicated good accuracy of the proposed mathematical algorithm in sifting the FCG from the TCM formula, which provided a methodological reference for discovering functional components and interpreting molecular mechanisms of the TCM formula in treating complex diseases.

The Inverse Correlation of Isoflavone Dietary Intake and Headache in Peri- and Post-Menopausal Women

This study investigated the relationship between headache and dietary consumption of a variety of nutrients in middle-aged women. This cross-sectional analysis used first-visit records of 405 women aged 40–59 years. The frequency of headaches was assessed using the Menopausal Health-Related Quality of Life Questionnaire. Of the 43 major nutrient intakes surveyed using the brief-type self-administered diet history questionnaire, those that were not shared between women with and without frequent headaches were selected. Multiple logistic regression analysis was used to identify nutrients independently associated with frequent headaches. After adjusting for background factors related to frequent headache (vasomotor, insomnia, anxiety, and depression symptoms), the estimated dietary intake of isoflavones (daidzein + genistein) (mg/1000 kcal/day) was negatively associated with frequent headaches (adjusted odds, 0.974; 95% confidence interval, 0.950–0.999). Moreover, the estimated isoflavone intake was not significantly associated with headache frequency in the premenopausal group, whereas it significantly correlated with that in the peri- and post-menopausal groups. Headache in peri- and post-menopausal women was inversely correlated with the dietary intake of isoflavones. Diets rich in isoflavones may improve headaches in middle-aged women.

Effects of herbal medicine (Danggwijagyaksan) for treating climacteric syndrome with a blood-deficiency-dominant pattern: A randomized, double-blind, placebo-controlled pilot trial

Background

Danggwijagyaksan (DJS) has been one of the most widely used herbal medicines for gynecological disorders in traditional East Asian medicine. Several clinical studies about DJS have shown improvement in menopausal symptoms. This pilot study aimed to evaluate the efficacy, safety and feasibility of DJS for treating climacteric syndrome with a blood-deficiency-dominant pattern.

Methods

This was a randomized, double-blind, placebo-controlled pilot trial. A group of 45-to 60-year-old women with climacteric syndrome were registered for the trial. The participants received treatment over a 4-week period and were then followed for 4 weeks. The primary outcome measure was the mean change in the Menopause Rating Scale (MRS). Secondary outcome measures included the World Health Organization Quality of Life-BREF (WHOQOL-BREF), the Blood-Deficiency Scoring System (BDSS), lean body mass, and serum hormone levels, including follicle-stimulating hormone (FSH) and estradiol (E₂) levels.

Results

The MRS and BDSS scores decreased significantly in both groups, but the differences between two groups were not significant. The WHOQOL-BREF scores increased in the control group. No statistically meaningful differences in serum hormone levels or lean body mass were observed in both groups. There were no serious adverse events, and the laboratory tests were within the normal range. The recruitment rate, completion rate and medication adherence rate were over 90% in both groups, indicating high feasibility.

Conclusions

DJS showed clinical effectiveness in the treatment of climacteric syndrome with a blood-deficiency-dominant pattern. Additionally, DJS was shown to be safe and feasible for a large-scale study to confirm the efficacy of the treatment.

Muscle and joint pains in middle-aged women are associated with insomnia and low grip strength: a cross-sectional study

Background: Although muscle and joint pains are among the most common symptoms in menopausal transition, their underlying mechanisms are not precisely known. This study aimed to investigate the factors associated with myalgia and arthralgia in middle-aged women.Methods: We analyzed in a cross-sectional manner the first-visit records of 305 Japanese women aged 40-59 years who enrolled in a health and nutrition education program at a menopause clinic. The prevalence of muscle and joint pains was estimated according to the participants' responses to the Menopausal Health-Related Quality of Life Questionnaire. Background characteristics including age, menopause status, body composition, cardiovascular parameters and physical fitness, as well as other menopausal symptoms including vasomotor symptoms, insomnia, depression and anxiety, were assessed for associations with daily myalgia and arthralgia.Results: The percentage of women who were bothered by muscle and joint pains almost every day of the previous week was 56.1%. Characteristics associated with these symptoms were: low stature; high body fat percentage; low grip strength; and high vasomotor, insomnia, depression and anxiety symptom scores. Multivariate logistic regression analysis revealed that independently associated factors (adjusted odds ratio [95% confidence interval]) for daily myalgia/arthralgia were low hand-grip strength (kgf) (0.92 [0.87-0.97]) and insomnia symptom score (1.20 [1.07-1.34]).Conclusion: Muscle and joint pains are highly prevalent in Japanese middle-aged women. Low grip strength and insomnia are independently associated with these symptoms. Treatment of insomnia in this population might improve myalgia/arthralgia, and in turn, help restore grip strength, or treatment of hand pain might conversely reduce insomnia in addition to improvement in grip strength.

Chilliness in Japanese middle-aged women is associated with anxiety and low n-3 fatty acid intake

Objective: This cross-sectional study investigated chilliness, which is the most prevalent sexual-vasomotor symptom in middle-aged Japanese women.Methods: First-visit records of 475 Japanese women (age 40-65 years) enrolled in the health and nutrition education program at a menopause clinic were analyzed. Chilliness was estimated based on responses to the Menopausal Symptom Scale. Effects of age, menopausal status, body composition, cardiovascular parameters, resting energy expenditure, physical fitness, menopausal symptoms, lifestyle, and estimated daily intake of nutrients were assessed using a multivariate logistic regression analysis.Results: Severe chilliness was found in 28.4% of women. It was not related to age, menopausal status, body mass index, or body fat percentage. The anxiety subscale score of the Hospital Anxiety and Depression Scale was the sole background characteristic independently associated with severe chilliness (adjusted odds ratio, 1.09; 95% confidence interval, 1.04-1.15 per point). Daily intakes of vitamin D and n-3 fatty acids were significantly lower in women with severe chilliness. Daily intake of n-3 fatty acids was negatively associated with severe chilliness after adjustment (odds ratio, 0.54; 95% confidence interval, 0.29-0.95 per g/1000 kcal intake).Conclusions: Chilliness is associated with anxiety and low intake of n-3 fatty acids.

Successful treatment of intractable menstrual migraine with the traditional herbal medicine tokishakuyakusan

In this report, we present the successful treatment of five consecutive cases of premenopausal women suffering from severe menstrual migraine with tokishakuyakusan (TSS). Two patients were complicated by tension-type headache (TTH), and another patient was by medication overuse headache (MOH). The effects of triptans were limited in all of them. After starting TSS, they showed dramatic improvement in the severity and frequency of their attacks. The patients with TTH and MOH also showed dramatic improvement in their symptoms. TSS could be a promising alternative choice for patients with intractable menstruation-related headaches that are refractory to conventional treatments, including triptans.

Traditional Oriental Medicines and Alzheimer's Disease

Alzheimer’s disease (AD), which is the most major cause of dementia, is a progressive neurodegenerative disease that affects cognitive functions. Even though the prevalence of AD is continuously increasing, few drugs including cholinesterase inhibitors and N-methyl D-aspartate-receptor antagonists were approved to treat AD. Because the clinical trials of AD drugs with single targets, such as β-amyloid and tau, have failed, the development of multi-target drugs that ameliorate many of the symptoms of AD is needed. Thus, recent studies have investigated the effects and underlying mechanisms of herbal formulae consisting of various herb combinations used to treat AD. This review discusses the results of clinical and nonclinical studies of the therapeutic efficacy in AD and underlying mechanisms of the herbal formulae of traditional Oriental medicines and bioactive compounds of medicinal plants.

Tea Seed Oil Prevents Obesity, Reduces Physical Fatigue, and Improves Exercise Performance in High-Fat-Diet-Induced Obese Ovariectomized Mice

Menopause is associated with changes in body composition (a decline in lean body mass and an increase in total fat mass), leading to an increased risk of metabolic syndrome, nonalcoholic fatty liver disease, and heart disease. A healthy diet to control body weight is an effective strategy for preventing and treating menopause-related metabolic syndromes. In the present study, we investigated the effect of long-term feeding of edible oils (soybean oil (SO), tea seed oil (TO), and lard oil (LO)) on female ovariectomized (OVX) mice. SO, TO, and LO comprise mainly polyunsaturated fatty acids (PUFA), monounsaturated fatty acids (MUFA), and saturated fatty acids (SFA), respectively. However, there have been quite limited studies to investigate the effects of different fatty acids (PUFA, MUFA, and SFA) on physiological adaption and metabolic homeostasis in a menopausal population. In this study, 7-week-old female Institute of Cancer Research (ICR) mice underwent either bilateral laparotomy (sham group, n = 8) or bilateral oophorectomy (OVX groups, n = 24). The OVX mice given a high-fat diet (HFD) were randomly divided into three groups: OVX+SO, OVX+TO, and OVX+LO. An HFD rich in SO, TO, or LO was given to the OVX mice for 12 weeks. Our findings revealed that the body weight and relative tissues of UFP (uterus fatty peripheral) and total fat (TF) were significantly decreased in the OVX+TO group compared with those in the OVX+SO and OVX+LO groups. However, no significant difference in body weight or in the relative tissues of UFP and TF was noted among the OVX+SO and OVX+LO groups. Furthermore, mice given an HFD rich in TO exhibited significantly decreased accumulation of liver lipid droplets and adipocyte sizes of UFP and brown adipose tissue (BAT) compared with those given an HFD rich in SO or LO. Moreover, replacing SO or LO with TO significantly increased oral glucose tolerance. Additionally, TO improved endurance performance and exhibited antifatigue activity by lowering ammonia, blood urea nitrogen, and creatine kinase levels. Thus, tea seed oil (TO) rich in MUFA could prevent obesity, reduce physical fatigue, and improve exercise performance compared with either SO (PUFA)- or LO(SFA)-rich diets in this HFD-induced obese OVX mice model.

Dizziness in peri- and postmenopausal women is associated with anxiety: a cross-sectional study

Background

Although dizziness is one of the most common symptoms of menopause, the underlying mechanism is not precisely known. Therefore, this study aimed to investigate the prevalence of, and the factors associated with, dizziness in peri- and postmenopausal women.

Methods

We conducted a cross-sectional study in which we analyzed the first-visit records of 471 Japanese women aged 40 to 65 years who enrolled in a health and nutrition education program at a menopause clinic. The prevalence of dizziness was estimated according to the participants’ responses to the Menopausal Health-Related Quality of Life Questionnaire. The background characteristics of age, menopause status, body composition, cardiovascular parameters, basal metabolism, and physical fitness; other menopausal symptoms, including vasomotor, insomnia, depression, and anxiety symptoms; and lifestyle characteristics were assessed for their associations with dizziness.

Results

The percentage of women who suffered from dizziness once a week or more frequently was 35.7%. Compared to the women without dizziness, those with the symptom were younger; had a higher body weight, body mass index, body fat percentage, muscle mass, and waist-to-hip ratio; had higher systolic pressure; were slower in reaction time; had higher physical and psychological symptom scores of menopause; exercised less regularly; and consumed less alcohol. A multivariate logistic regression analysis revealed that the anxiety symptom, which was evaluated by the Hospital Anxiety and Depression Scale, was the sole factor that was independently associated with dizziness (adjusted odds ratio 1.14; 95% confidence interval 1.08–1.20).

Conclusions

Dizziness is highly prevalent in Japanese peri- and postmenopausal women and it is associated with anxiety. The treatment of anxiety in this population might improve the symptom.

Danggwijagyaksan for climacteric syndrome in peri- and postmenopausal women with a blood-deficiency dominant pattern: study protocol for a randomized, double-blind, placebo-controlled pilot trial

Background

This study aims to explore the safety, efficacy, and feasibility of Danggwijagyaksan (DJS) for alleviating climacteric syndrome in peri- and postmenopausal women with a blood-deficiency dominant pattern.

Methods/design

This is a randomized, double-blind, placebo-controlled pilot clinical trial. A total of 34 women with climacteric syndrome who have signed informed consent forms will be registered in this study. Placebo or DJS will be randomly assigned to the participants in an equal proportion. The participants will visit the clinical trial center every 2 weeks and receive placebo or DJS granules. The treatment period is 4 weeks and the administration frequency is three times daily. Data will be collected from the participants at baseline, at week 5, and at week 9 after random allocation. The primary outcome measure will be the mean change in the Menopause Rating Scale from baseline to week 5. Secondary outcome measures will include the World Health Organization Quality of Life-BREF (WHOQOL-BREF) score, the Blood Deficiency Scoring System score, lean body mass, and blood tests, including serum follicle-stimulating hormone and estradiol concentration. To assess the safety of DJS, a laboratory test will be conducted before and after treatment and the participants will be asked about any occurrence of adverse events every visit. The recruitment rate, completion rate, and medication adherence will also be calculated, to assess feasibility.

Discussion

The findings of this study will provide the basis for a full-scale randomized controlled trial to confirm the safety and efficacy of DJS for the treatment of climacteric syndrome in peri- and postmenopausal women.

Effect of soy lecithin on fatigue and menopausal symptoms in middle-aged women: a randomized, double-blind, placebo-controlled study

BACKGROUND

Lecithin is a complex mixture of phospholipids which compose lipid bilayer cell membranes. Lipid replacement therapy, or administration of phospholipids for the purpose of repairing the dmaged cell membranes, had been shown to alleviate fatigue. The present study aimed to investigate the effect of soy lecithin on fatigue in middle-aged women, as well as other menopausal symptoms and various health parameters.

METHODS

This randomized, double-blind, placebo-controlled study included 96 women aged 40 to 60 years who complained of fatigue. The participants were randomized to receive active tablets containing high-dose (1200 mg/day; n = 32) or low-dose (600 mg/day; n = 32) soy lecithin, or placebo (n = 32), for 8 weeks. The following parameters were evaluated: age, menopausal status, lifestyle factors, physical and psychological symptoms of menopause, subjective symptoms of insomnia and fatigue, body composition, cardiovascular parameters, and physical activities and objective sleep states obtained from actigraphy before and 4 and 8 weeks after treatment. Fatigue was evaluated using the Profile of Mood States (POMS)-brief, Menopausal Health-Related Quality of Life questionnaire, Chalder Fatigue Scale, and Brief Fatigue Inventory.

RESULTS

Eighty-nine women completed the study. There were no significant differences in the changes in Chalder Fatigue Scale score (placebo vs low-dose vs high-dose groups: -2.9 ± 1.1, -3.2 ± 1.1, and -3.5 ± 1.0; P = 0.79). On the other hand, the improvements were greater in the high-dose group compared with the placebo group concerning vigor scores in the POMS-brief (1.9 ± 0.7 vs 0.2 ± 0.6; P = 0.02), diastolic blood pressure (-4.1 ± 1.8 vs 1.2 ± 1.9; P = 0.05), and cardio-ankle vascular index (-0.4 ± 0.2 vs 0.07 ± 0.1; P = 0.03) after 8 weeks of treatment.

CONCLUSIONS

High-dose (1200 mg/day) soy lecithin not only increases vigor, but also lowers the diastolic blood pressure and cardio-ankle vascular index in middle-aged women who present with fatigue.

Sansoninto as evidence-based remedial medicine for depression-like behavior

In vitro screening methods using cultured Neuro2a cells to examine the activation (phosphorylation) of extracellular signal-regulated kinase (ERK) 1/2 and promotion of neurite outgrowth revealed that the extracts of 5 Kampo (Japanese traditional) formulations have potential as medicines for the treatment of behavioral abnormalities. Since sansoninto (SAT) extract exerted stronger effects than the other candidates tested, we investigated whether its oral administration ameliorates the pathologies of some mouse models of behavioral impairments. The results obtained suggested that SAT extract exerted anti-depression-like effects in the forced swim test, which may be mediated by the up-regulated expression of brain-derived neurotrophic factor (BDNF) in the hippocampus. They may also be mediated by the enhanced phosphorylation of the cAMP response element-binding protein (CREB) via the mitogen-activated protein kinase (MAPK) cascade and Ca²⁺/calmodulin-dependent protein kinase II (CaMK II) cascade, a downstream signaling cascade of the N-methyl-D-aspartate (NMDA) receptor. These results indicate that the extract of SAT has potential as a new remedial medicine in the treatment of depression-like behavior.

Broadening our perspectives on complementary and alternative medicine for menopause: A narrative review

Complementary and alternative medicine (CAM) is widely used for menopause, although not all women disclose use to their healthcare providers. This narrative review aims to expand providers' understanding of cross-cultural approaches to treating and managing menopause by providing an overarching framework and perspective on CAM treatments. Increased provider understanding and awareness may improve not only provider-patient communication but also effectiveness of treatments. The distinction between illness (what patients suffer) and disease (what physicians treat) highlights the gap between what patients seek and doctors provide, and may help clarify why many women seek CAM at menopause. For example, CAM is often sought by women for whom biomedicine has been unsuccessful or inaccessible. We review the relevance to menopause of three CAM categories: natural products, mind-body practices including meditation, and other complementary health approaches including traditional Chinese medicine (TCM) and Japanese Kampo. Assessing the effectiveness of CAM is challenging because of the individualized nature of illness patterns and associated treatments, which complicate the design of randomized controlled trials. Because many women seek CAM due to inefficacy of biomedical treatments, or cultural or economic marginalization, biomedical practitioners who make an effort to learn about CAM and ask patients about their CAM use or interest may dramatically improve the patient-provider relationship and rapport, as well as harnessing the 'meaning response' (Moerman, 2002) imbued in the clinical encounter. By working with women to integrate their CAM-related health-seeking behaviors and treatments, providers may also boost the efficacy of their own biomedical treatments.

Subgrouping of Japanese middle-aged women attending a menopause clinic using physical and psychological symptom profiles: a cross-sectional study

BACKGROUND

Women in the menopausal transition and the postmenopausal period are affected with vasomotor symptoms, urogenital atrophy, sexual dysfunction, somatic symptoms, cognitive difficulty, sleep disturbance, and psychological problems. It is important to gain a better understanding of the complexity and diversity of climacteric disturbance in order to optimize treatments for individual patients. The aim of this study was to identify subgroups of Japanese perimenopausal and postmenopausal women attending a menopause clinic based on their physical and psychological symptom profiles.

METHODS

We administered the Menopausal Health-Related Quality of Life questionnaire to 491 Japanese women aged 40-64 years who had enrolled in the Systematic Health and Nutrition Education Program at the Menopause Clinic of the Tokyo Medical and Dental University Hospital between 2005 and 2012. We performed a principal component analysis followed by a hierarchical cluster analysis of the responses to 9 physical and 12 psychological items on the questionnaire.

RESULTS

The first analysis extracted 3 principal components that defined the variance of physical and psychological symptom profiles: depression, somatic, and vasomotor/sleep. A subsequent cluster analysis was performed based on the 3 principal components to generate 4 clusters, CL8 (N = 162; 33.0%), CL6 (N = 111; 22.6%), CL5 (N = 102; 20.8%), and CL4 (N = 116; 23.6%). CL8 included women who only had mild-to-moderate musculoskeletal pains and tiredness. All women in CL6, CL5, and CL4 described their musculoskeletal pains and tiredness as moderate to severe. The women in CL5 also had moderate-to-severe vasomotor symptoms, while the women in CL4 also suffered from moderate-to-severe psychological symptoms, such as depression, anxiety, and insomnia.

CONCLUSIONS

Distinct subgroups of Japanese perimenopausal and postmenopausal women were identified based on their symptom profiles. Menopausal symptoms were shown to accumulate in this population in the order of musculoskeletal pains and tiredness, vasomotor symptoms, and psychological symptoms.
