Effect of Jiawei qingxuan jiangya decoction on blood pressure variability and sex hormone levels in perimenopausal female patients with hypertension.

To explore the effect of Jiawei Qingxuan Jiangya Decoction on blood pressure variability and sex hormone levels in perimenopausal women with hypertension. A total of 400 perimenopausal female hypertensive patients admitted to the hospital from June 2019 to June 2020 were randomly divided into observation group and control group, with 200 cases in each group. The patients in the control group took orally benazepril hydrochloride tablets, and the observation group was added with Jiawei Qingxuan Jiangya Decoction on the basis of the control group. The course of treatment was 1 month. The clinical efficacy of the two groups and the 24h blood pressure variability (BPV) and sex hormone levels before and after treatment were compared. The total effective rate of the observation group was significantly higher than that of the control group (P<0.05); the 24h BPV of the two groups after treatment was significantly lower than that before the treatment, and the reduction in the observation group was greater (P<0.05); the serum estradiol in the observation group after treatment was significantly increased, and the level of follicle stimulating hormone was significantly reduced, and compared with the control group after treatment, the difference was statistically significant (P<0.05). Jiawei Qingxuan Jiangya Decoction for treating hypertension in perimenopausal women can effectively reduce blood pressure, improve short-term blood pressure variability, regulate sex hormone levels to a certain extent, and correct endocrine disorders. It is worthy of clinical promotion.

Modulatory effects of R10 fraction of garlic (Allium sativum L.) on hormonal levels, T cell polarization, and fertility-related genes in mice model of polycystic ovarian syndrome.

Polycystic ovary syndrome (PCOS) is an inflammatory endocrine-metabolic disorder related to reproductive system characterized by polycystic ovarian morphology, androgen excess, and chronic anovulation. Current treatments haven't been very successful in PCOS treatment and the problem still remains as a challenge. Therefore, new approaches should be applied to overcome the disease. Previous studies demonstrated immunomodulatory effects of R10 fraction of garlic in the treatment of inflammatory conditions such as cancer. Considering previous studies suggesting immunomodulatory therapy for PCOS, therapeutic effects of R10 fraction was evaluated in a mouse model of PCOS. To do so, PCOS was developed by intramuscular injection of estradiol valerate. Treatment with R10 fraction, isolated from garlic, was performed and the alterations in hormonal levels (estradiol, progesterone, and testosterone), T cell polarization markers (IFN-γ, IL-4, and IL-17), and expression of fertility-related genes (Gpx3 and Ptx3) were evaluated. The results showed that hormonal levels were elevated in PCOS model comparing to normal animals but were markedly modulated after treatment with R10 fraction. Moreover, a severe disturbance in T cell polarization with a significant reduction of fertility-related genes expression were detected in PCOS-induced ovaries. Treatment with R10 fraction also represented modulatory effects on T cell polarization by increasing IL-4 and decreasing IL-17 and IFN-γ levels. Accordingly, fertility-related genes were also modulated following treatment with R10 fraction in PCOS. Our study elucidated that R10 fraction of garlic possess immunomodulatory effects alleviating PCOS symptoms. This approach could be adjusted to give rise the optimum therapeutic results and considered as a candidate therapeutic approach for PCOS.

Sex-tailored pharmacology and COVID-19: Next steps towards appropriateness and health equity.

Making gender bias visible allows to fill the gaps in knowledge and understand health records and risks of women and men. The coronavirus disease 2019 (COVID-19) pandemic has shown a clear gender difference in health outcomes. The more severe symptoms and higher mortality in men as compared to women are likely due to sex and age differences in immune responses. Age-associated decline in sex steroid hormone levels may mediate proinflammatory reactions in older adults, thereby increasing their risk of adverse outcomes, whereas sex hormones and/or sex hormone receptor modulators may attenuate the inflammatory response and provide benefit to COVID-19 patients. While multiple pharmacological options including anticoagulants, glucocorticoids, antivirals, anti-inflammatory agents and traditional Chinese medicine preparations have been tested to treat COVID-19 patients with varied levels of evidence in terms of efficacy and safety, information on sex-targeted treatment strategies is currently limited. Women may have more benefit from COVID-19 vaccines than men, despite the occurrence of more frequent adverse effects, and long-term safety data with newly developed vectors are eagerly awaited. The prevalent inclusion of men in randomized clinical trials (RCTs) with subsequent extrapolation of results to women needs to be addressed, as reinforcing sex-neutral claims into COVID-19 research may insidiously lead to increased inequities in health care. The huge worldwide effort with over 3000 ongoing RCTs of pharmacological agents should focus on improving knowledge on sex, gender and age as pillars of individual variation in drug responses and enforce appropriateness.

Antidepressant-like effects of acupuncture via modulation of corticosterone, sex hormones, and hippocampal BDNF expression in male rats.

BACKGROUND: Post-weaning social isolated rodents exhibit pathophysiological changes associated with depression including adrenal axis hyperactivity, gonadal hormone level disturbances, molecular alterations in hippocampus, and immobility behavior in the forced swimming test (FST). Although acupuncture by absorbable thread implantation (acu-catgut, AC) elicits antidepressant-like effects in social isolated rats, AC effects on neuroendocrine and hippocampal molecular alterations have been less characterized. OBJECTIVE: To investigate the participation of gonadal hormones, corticosterone, and brain-derived neurotrophic factor (BDNF) hippocampal expression, on the AC antidepressant-like effects in social isolated male rats. METHODS: Sprague-Dawley male rats were raised in social isolation (SI) or standard conditions, for 11 weeks. AC (on Baihui (Du20), Yintang (E X-HN3), Shenshu (BL 23), Pishu (BL 20), Ganshu (BL 18), Xinshu (BL 15) and Guanyuan (Ren 4)), or Sham-AC (puncturing of acupoints without embedding the thread), was applied during the last three weeks of isolation period. Rats were evaluated in the FST; hormones plasmatic levels and hippocampal BDNF content were quantified by ELISA and Western blotting, respectively. RESULTS: Social isolated rats showed more immobility in the FST and had lower testosterone and estradiol levels, higher corticosterone levels, and reduced hippocampal BDNF content than controls. BDNF level in hippocampus inversely correlated to depression-like behavior. AC but not sham-AC normalized immobility behavior, steroid hormone levels, and BDNF content, as in rats raised in a social environment. CONCLUSIONS: AC antidepressant effect could be related to an improvement of hippocampal BDNF protein expression, as well as corticosterone and sex hormones disturbances associated with prolonged exposure to stress caused by social isolation. Present findings have implications for depression treatment in individuals early exposed to stress.

Protective effects of ginseng stem-leaf saponins on D-galactose-induced reproductive injury in male mice.

Panax ginseng is a perennial plant in the Araliaceae family. In this study, we investigated the protective effects of ginseng stem-leaf saponins (GSLS) isolated from P. ginseng against D-galactose-induced reproductive function decline, oxidative stress, and inflammatory response. Reproductive injuries were induced in mice via the subcutaneous injection of D-galactose (300 mg/kg) for six weeks. The mice were then treated with GSLS by intragastric administration. GSLS inhibited markers of oxidative stress and inflammatory cytokines induced by D-galactose in serum, liver and kidney, whereas GSLS increased the activities of antioxidant enzymes. Compared to the mice treated only with D-galactose, GSLS treatment significantly increased the average path velocity, straight line velocity, curvilinear velocity, and amplitude of the lateral head displacement of mouse sperm. Meanwhile, GSLS significantly increased the testosterone level and reduced the cortisol, FSH, and LH levels. Histopathological examination revealed alterations in the number and the arrangement of spermatogenic cells in the seminiferous tubules of the mice in the GSLS group. GSLS treatment suppressed MAPKs pathway activation in testes. These results suggest that GSLS can attenuate D-galactose-induced oxidative stress and inflammatory response in serum, liver and kidney, and ameliorate reproductive damage by inhibiting MAPKs signaling pathway.

Effects of total flavonoids from Eucommia ulmoides Oliv. leaves on polycystic ovary syndrome with insulin resistance model rats induced by letrozole combined with a high-fat diet.

ETHNOPHARMACOLOGICAL RELEVANCE: Eucommia ulmoides Oliv. leaves are the dry leaves of Eucommia ulmoides Oliv. Modern studies have shown that Eucommia ulmoides Oliv. leaves and its extracts have many pharmacological effects, such as regulating hypothalamus pituitary ovary (HPO) axis function, estrogen like effects, correcting insulin resistance (IR), regulating lipids, and reducing weight, which are consistent with the clinical manifestations in polycystic ovary syndrome (PCOS) patients. PCOS patients often have HPO axis disorder, low estrogen, high androgen, high IR complication rate, and obesity. Previous preclinical studies have shown that total flavonoids from Eucommia ulmoides Oliv. leaves (TFEL) can improve the imbalance in sex hormone secretion in perimenopausal animal models by regulating the function of the HPO axis. Thus, it is important to understand if flavonoids are the active parts of Eucommia ulmoides Oliv. leaves that interfere with polycystic ovary syndrome with insulin resistance (PCOS-IR), and determine the regulatory role they play in sex hormones and IR? AIM OF THE STUDY: Investigate the phosphatidylinositol 3-kinase/protein kinase B (PI3K/AKT) signaling pathway in the ovary and kisspeptin/insulin like growth factor/leptin receptor1/androgen receptor (Kiss1/IGF-1/LEPR/AR) in the HPO axis to determine the mechanism of TFEL intervention in a rat model of PCOS-IR model rats. MATERIALS AND METHODS: A rat model of PCOS-IR was established using a high-fat diet (49 d) combined with letrozole (1 mg/kg·d, for 28 d). Then, metformin (300 mg/kg·d) and TFEL (220 mg/kg·d, 110 mg/kg·d, and 55 mg/kg·d) were administered continuously for 21 days. At the end of the experiment, samples were taken and the related indexes were measured. RESULTS: TFEL reduced the body weight, Lee's index, ovarian index, ovarian area and ovarian volume, increased serum E2, SHBG levels and ISI, decreased serum levels of T, LEP, INS, and FBG (whole blood), and reduced the HOMA-IR in rats with PCOS-IR. TFEL downregulate Kiss1, IGF-1, and AR in the arcuate nucleus of hypothalamus, and upregulate Kiss1, downregulate IGF-1 and AR in the pituitary gland, and upregulate Kiss1, downregulate IGF-1, LEPR, and AR in the ovary of rats with PCOS-IR. TFEL could downregulate p-IRS-1Ser307, upregulate IRS-1, p-IRS-1Tyr895, PI3Kp85α, p-PI3Kp85α, AKT, p-AKT, and GLUT4 in the ovary, and ameliorated histopathological changes in the ovary and pancreas of rats with PCOS-IR. CONCLUSION: TFEL can inhibit ovarian hyperplasia, regulate disorders of glucose and lipid metabolism and improve the secretion of sex hormones, by regulating the expression of PI3K/AKT signaling pathway-related proteins in the ovary and Kiss1/IGF-1/LEPR/AR in the HPO axis.

To study the mechanism of Cuscuta chinensis Lam. And Lycium barbarum L. in the treatment of asthenospermia based on network pharmacology.

ETHNOPHARMACOLOGICAL RELEVANCE: Cuscuta chinensis Lam. and Lycium barbarum L. (SC-FL) is a commonly used kidney tonic Chinese medicine combination that is widely used in the clinical treatment of oligoasthenospermia.However, its specific mechanism remains unclear and requires in-depth study. AIM OF THE STUDY: To explore the potential targets of SC-FL in the treatment of oligoasthenospermia using network pharmacology, and to verify the results with in vivo and in vitro experiments. MATERIALS AND METHODS: A herb-compound-target-disease network and PPI network were constructed with Cytoscape software. The targets of SC-FL for the treatment of male sterility were introduced into a bioinformatics annotation database, and the GO and KEGG databases were used for pathway enrichment analysis. Subsequently, Tripterygium wilfordii Hook. f. (GTW) polyglycoside was used to induce a spermatogenic dysfunction model in GC-1 spg cells and SD male rats in in vitro and in vivo experiments, respectively. The SC-FL and PI3K pathway inhibitor LY294002 was used to intervene in the spermatogenic dysfunction model to detect the expression of proteins and mRNA related to the PI3K pathway and to detect the indicators related to proliferation and apoptosis. RESULTS: In in vitro experiments, the percentage of spermatogenic cells and the proportion of GC-1 spg cells at G0/G1 and G2/M stages in the model group (GTW group) and the inhibitor group (LY group) were significantly decreased (P < 0.01) compared with the blank control group (NC group). The apoptosis rate of the GTW group was significantly increased (P < 0.01). The ultrastructures of GC-1 spg cells in the GTW group and LY group were obviously destroyed. Compared with the GTW group, the SC-FL group had a significantly reduced apoptosis rate of GC-1 spg cells, reduced percentage of cells in S phase, and a significantly improved mitochondrial membrane potential. SC-FL can repair the ultrastructure of GC-1 spg cells damaged by GTW. The above effects of SC-FL are closely related to up-regulation of GFRa1, RET, PI3K, p-AKT, and Bcl-2 and down-regulation of BAD and BAX proteins and mRNA expression. In vivo, compared with the GTW group, the body mass, testicular mass, and epididymal weight of the GTW + SC-FL group were significantly increased (P < 0.01). Sperm concentrations and the PR + NP of GTW + SC-FL were significantly higher than in the GTW group (P < 0.01 or P < 0.05). FSH, LH, and T levels in the GTW + SC-FL and LY + SC-FL groups were significantly higher than those in the GTW and LY group (P < 0.01 or P < 0.05). HE staining results showed that the morphology of testicular tissue in the GTW + SC-FL and LY + SC-FL groups was superior to that in the GTW and LY group. The above effects of SC-FL are closely related to the up-regulation of proteins and mRNA expression of PI3K, p-AKT, and Bcl-2. CONCLUSION: Through the PI3K/Akt signaling pathway, SC-FL up-regulates GFRa1, RET, PI3K, p-AKT, and Bcl-2, and down-regulates the expression of BAD and BAX proteins and mRNA, thus reducing the percentage of GC-1 spg cells in S-phase, significantly increasing the mitochondrial membrane potential, significantly reducing cell apoptosis, and improving sperm counts and viability.

The Protective Effects of L-Carnitine and Zinc Oxide Nanoparticles Against Diabetic Injury on Sex Steroid Hormones Levels, Oxidative Stress, and Ovarian Histopathological Changes in Rat.

Diabetes mellitus is a common chronic metabolic disorder. This study aimed to investigate the effects of co-treatment with L-carnitine (LC) and zinc oxide nanoparticles (ZnONPs) on serum levels of sex hormones, oxidative stress, and ovarian histopathology in streptozotocin (STZ)-induced diabetic rats. Female Wistar rats (n = 56, 180-220 g) received a single intraperitoneal (IP) injection of STZ (65 mg/kg). They were randomly assigned into the following groups: diabetic group (Dia), Dia+Met group (100 mg metformin/kg/day), Dia+LC group (200 mg/kg/day), Dia+ZnONPs group (10 mg/kg/day), and Dia+LC+ZnONPs group (200 mg LC/kg/day and 10 mg ZnONPs/kg/day). Control group (Ctl) received the same volume of STZ solvent. After 21 days of treatment, blood serum was centrifuged for sex hormone assays. The right ovary was used for biochemical analysis, and the left ovary was fixed in 10% neutral buffered formalin for histological assessment. The levels of estradiol, progesterone, FSH, and LH significantly increased in the Dia+ZnONPs+LC group (P < 0.001) compared with the Dia group. Co-treatment with LC and ZnONPs reduced malondialdehyde and carbonyl protein and increased glutathione, catalase, and superoxide dismutase activities in ovarian tissue compared with the Dia group (P < 0.05). Moreover, the number of all ovarian follicles significantly increased in this group compared with the Dia group (P < 0.05). The results of this study indicated that co-treatment with LC and ZnONPs could preserve ovarian function by increasing sex hormones levels and antioxidant activity and decreasing lipid peroxidation in diabetic rats. Therefore, this compound supplementation may improve ovulation and fertility in people with diabetes mellitus.

ERα Signaling in GHRH/Kiss1 Dual-Phenotype Neurons Plays Sex-Specific Roles in Growth and Puberty.

Gonadal steroids modulate growth hormone (GH) secretion and the pubertal growth spurt via undefined central pathways. GH-releasing hormone (GHRH) neurons express estrogen receptor α (ERα) and androgen receptor (AR), suggesting changing levels of gonadal steroids during puberty directly modulate the somatotropic axis. We generated mice with deletion of ERα in GHRH cells (GHRHΔERα), which displayed reduced body length in both sexes. Timing of puberty onset was similar in both groups, but puberty completion was delayed in GHRHΔERα females. Lack of AR in GHRH cells (GHRHΔAR mice) induced no changes in body length, but puberty completion was also delayed in females. Using a mouse model with two reporter genes, we observed that, while GHRHtdTom neurons minimally colocalize with Kiss1hrGFP in prepubertal mice, ∼30% of GHRH neurons coexpressed both reporter genes in adult females, but not in males. Developmental analysis of Ghrh and Kiss1 expression suggested that a subpopulation of ERα neurons in the arcuate nucleus of female mice undergoes a shift in phenotype, from GHRH to Kiss1, during pubertal transition. Our findings demonstrate that direct actions of gonadal steroids in GHRH neurons modulate growth and puberty and indicate that GHRH/Kiss1 dual-phenotype neurons play a sex-specific role in the crosstalk between the somatotropic and gonadotropic axes during pubertal transition.SIGNIFICANCE STATEMENT Late maturing adolescents usually show delayed growth and bone age. At puberty, gonadal steroids have stimulatory effects on the activation of growth and reproductive axes, but the existence of gonadal steroid-sensitive neuronal crosstalk remains undefined. Moreover, the neural basis for the sex differences observed in the clinical arena is unknown. Lack of ERα in GHRH neurons disrupts growth in both sexes and causes pubertal delay in females. Deletion of androgen receptor in GHRH neurons only delayed female puberty. In adult females, not males, a subset of GHRH neurons shift phenotype to start producing Kiss1. Thus, direct estrogen action in GHRH/Kiss1 dual-phenotype neurons modulates growth and puberty and may orchestrate the sex differences in endocrine function observed during pubertal transition.

Effect of different levels of hydrolysable tannin intake on the reproductive hormones and serum biochemical indices in healthy female rats.

The present work aimed to find out the effect of different levels of hydrolysable tannin (HT) on serum hormonal profile, biochemical indices, lipid profile, apparent digestibility of nutrients and body weight gain in healthy female rats. Forty five adult healthy female rats of 8 weeks old were randomly divided into five equal groups. Different doses of HT 0, 0.5, 1, 1.5 and 2% were administered daily to each rats group on the body weight basis for 6 weeks. The results had shown the reduction trend (p < 0.05) in the blood glucose, serum cholesterol, low density lipoprotein, testosterone, prolactin, ghrelin, total oxidative stress and serum iron levels; while an improvement (p < 0.05) was seen in serum follicle stimulating hormone, progesterone, luteinizing hormone, high density lipoprotein, IgM and total antioxidant capacity. However, no effect (p > 0.05) was noticed in serum IgG, protein, estrogen and calcium levels. A significant reduction (p < 0.05) was seen in the apparent nutrient digestibility and body weight gain. The results had shown improvement in the feed conversion ratio (p < 0.05) but non-significant decrease (p > 0.05) in the feed intake. The findings showed that HT had healthy effects on the serum biochemical indices and reproductive hormonal profile but had a negative impact on the nutrient digestibility. Thus, the study concluded that HT could be used as an herbal medicine for the treatment of leading metabolic and infertility diseases like obesity and polycystic ovarian syndrome in females.

Evaluation of the effect of vitamin D3 supplementation on quantitative and qualitative parameters of spermograms and hormones in infertile men: A Randomized controlled trial.

BACKGROUND: 25-Hydroxy Vitamin D3 is known to have an effect on reproductive system in both genders and may change the semen parameters in men. OBJECTIVE: Our study aimed to evaluate the effect of oral vitamin D3 supplementation on spermogram quantitative and qualitative parameters in infertile men. MATERIALS AND METHODS: This study was a triple-blind randomized controlled trial involving 62 infertile men with impaired spermatogonial tests. They were randomly divided into placebo and D3-supplemented groups. Spermograms and tests for LH (Luteinizing Hormone), FSH (Follicle Stimulating Hormone), TT (Total Testosterone), FT (Free Testosterone), SHBG (Sex Hormone Bonding Globulin), FAI (Free Androgen Index) and vitamin D3 levels were performed before and after the intervention. RESULTS: There were no significant differences between the two groups in parameters of the spermograms or serum levels of LH, FSH, TT, and FAI. In the intervention group, SHBG was significantly decreased after intervention (p = 0.01) and there was a significant increase in FT in the placebo group (p = 0.03). CONCLUSION: The intake of vitamin D3 did not change the quality and quantity of spermograms and serum levels of LH, FSH, TT, and FAI but affected FT and SHBG. Further studies are still needed to clarify the biological role of vitamin D3 on fertility particularly on male fertility. This study lays a foundation for more extensive studies on male infertility.

The ameliorative effects of marjoram in dehydroepiandrosterone induced polycystic ovary syndrome in rats.

AIMS: Polycystic ovary syndrome (PCOS) is a widespread chronic reproductive disorder that is associated with metabolic disturbances. Traditionally, the marjoram plant is well-known to restore hormonal balance and regulate the menstrual cycle. We aimed to investigate the ameliorative effects of marjoram extract on hormonal profiles, body and ovaries weight, insulin sensitivity, inflammation, and oxidative stress in a rat model of PCOS. MAIN METHODS: A 75 postpubertal (42 days old) female Wistar rats were randomly assigned into five groups (control, dehydroepiandrosterone (DHEA) induced-PCOS model, marjoram-treated PCOS rats, metformin-treated PCOS rats and the combination of marjoram+metfomin treated PCOS model). PCOS induction was performed by subcutaneous injection of DHEA 60 mg/kg daily for 24 days. Ovaries weight, adiponectin, hormonal levels, inflammatory, and oxidative stress biomarker levels were measured at the end of the treatment period using ELISA assay. KEY FINDINGS: The current study showed that marjoram significantly decreased ovaries' weight and the estradiol levels (P-value<0.05) compared to the DHEA group. Interestingly, marjoram improved insulin sensitivity as manifested by a significant increase in the adiponectin serum levels (P-value<0.05). Marjoram alone or in combination with metformin prominently decreased the IL-6 level and improved the levels of ovarian SOD and GPx enzymes (P-value<0.05). Additionally, the group treated with the combination of marjoram and metformin remarkably decreased the level of TBARS (P-value<0.05). SIGNIFICANCE: The present study established the beneficial effects of marjoram administration on DHEA-induced PCOS in female Wistar rats. The mechanistic effect includes improvement in the hormonal levels, ovaries weight, insulin sensitivity, antioxidants, and anti-inflammatory parameters.

Metformin administration during pregnancy attenuated the long-term maternal metabolic and cognitive impairments in a mouse model of gestational diabetes.

BACKGROUND: Gestational diabetes mellitus (GDM) is a metabolic disease that can have long-term adverse effects on the cognitive function of mothers. In our study, we explored the changes in metabolic health and cognitive function in mice of middle- and old- age after exposure to GDM, and whether metformin therapy during pregnancy provided long-term benefits. RESULTS: Mice with GDM demonstrated significant cognitive impairment in old age, which was associated with insulin resistance. Gestational metformin therapy was shown to increase insulin sensitivity and improve cognition. The ovarian aging rate was also accelerated in mice exposed to GDM during pregnancy, which may be related to fatty acid metabolism in the ovaries. CONCLUSION: Treatment with metformin during pregnancy was shown to improve fatty acid metabolism in ovarian tissues. METHOD: During pregnancy, mice were fed with a high-fat diet (GDM group) or a low-fat diet (Control group), and a third group received metformin while receiving a high-fat diet (Treatment group). At 12 months old, the mice completed an oral glucose tolerance test, insulin tolerance test, Morris water maze test, female sex hormones were measured, and metabolite profiles of tissue from the ovaries, hypothalamus, and pituitary glands were analysed using gas chromatography-mass spectrometry.

Chinese massage, Tui Na, combined with herbs improves clinical symptoms and regulates sex hormones in patients with mammary gland hyperplasia.

To study the effects of Tui Na therapy on patients with mammary gland hyperplasia.A total of 68 female patients with mammary gland hyperplasia were included in this retrospective study from May 2016 to May 2017 and assigned into control group (N = 34) treated with Rupixiao only (a proprietary Chinese medicine) or Tui Na group (N = 34) treated with Tui Na (Chinese massage) combined with Rupixiao. The pain intensity (visual analogous scale, VAS) and serum levels of luteinizing hormone (LH), estradiol (E2), prolactin (PRL), and progesterone (P) were examined before and after the treatment.The efficacies were 94.1% (32/34) in the Tui Na group and 76.5% (26/34) in the control group (P = .04). After treatment, VAS in Tui Na groups was significantly lower than that in control group (2.1 ±â€Š1.1 vs 3.1 ±â€Š1.1, P < .05). After follow-up for five months, the recurrence rates were 12.5% (4/32) in the Tui Na group and 23.1% (6/26) in the control group (P = .01). The levels of all 4 hormones in the Tui Na group increased significantly after treatment. In control group, only LH and E2 levels were significantly increased after treatment.In patients with mammary gland hyperplasia, Tui Na combined with Rupixiao could improve clinical symptoms, regulate sex hormone levels, and decrease the recurrence rate than Rupixiao alone. Our finding suggests that Tui Na can be potentially used for the treatment of mammary gland hyperplasia.

The Protective Effect of Pre-Moxibustion on Reproductive Hormones Profile of Rats with Tripterygium Glycosides-Induced Ovarian Damage.

BACKGROUND: Acupuncture and moxibustion have been proven to be conducive to improving the ovarian reserve. However, the mechanism of pre-moxibustion on Tripterygium glycosides (TG)-induced ovarian damage has not been previously reported. METHOD: Female rats were randomly divided into 5 groups: control, model (75 mg/kg TG, 14 days), preventive moxibustion 1 (PM1, receiving moxibustion for 4 weeks before TG administration), preventive moxibustion 2 (PM2, receiving moxibustion for 2 weeks before TG administration and another 2 weeks during TG administration), and preventive moxibustion 3 (PM3, receiving 4 weeks of moxibustion during TG administration). The estrous cycle of the animal was recorded after TG administration. Rats were sacrificed 14 days after TG administration. The reproductive hormones profiles in serum, ovary, and hypothalamic tissues were analyzed. RESULT: Pre-moxibustion could revert abnormal estrous cycles, relieve follicle damage, and improve abnormal secretion of reproductive hormones resulting from ovarian damage. However, both PM2 and PM3 were more effective than PM1. In addition, PM2 disclosed more advantages in regulating reproductive hormones abnormalities, while PM3 performed better in follicular development. CONCLUSION: In combination, the findings of this study suggest that pre-moxibustion is effective in protecting the ovary from damage in TG-induced ovarian damage rats. But different time points correspond to different modulation targets and mechanisms.

Evaluation of 1,25(OH)2D3 Effects on FOXP3, ROR-γt, GITR, and CTLA-4 Gene Expression in the PBMCs of Vitamin D-Deficient Women with Unexplained Recurrent Pregnancy Loss (URPL).

Background: Vitamin D insufficiency and deficiency can be associated with adverse effects on fetus and pregnancy outcomes. This study aimed at evaluating the effect of 1,25VitD3 on specific transcription factor and markers of Tregs and T helper 17 (Th17) cells in peripheral blood mononuclear cells (PBMCs) of women with unexplained recurrent pregnancy loss (URPL) as a case group and PBMCs of healthy women as a control group. Methods: Samples from 20 non-pregnant patients with a history of URPL were compared to 20 normal non-pregnant women. PBMCs were divided into three wells for each subject in the presence of 1,25VitD3 (50 nM, for 16 hours), phytohemagglutinin (10 µM; positive control), and without any treatment (negative control). By Real-time PCR (Taqman assay), specific transcription factors of Tregs and Th17 cells, forkhead box P3 (FOXP3), retinoic acid-related orphan receptor γt (ROR-γt), glucocorticoid-induced tumor necrosis factor receptor-related (GITR), and CTLA-4 mRNA expressions in two groups were measured. Results: FOXP3/ROR-γt mRNA expression in PBMCs decreased significantly in women experiencing URPL compared to the control group (p = 0.0001). Although 1,25VitD3 (50 nM) increased FOXP3 gene expression (p = 0.0001), it did not significantly affect ROR-γt gene expression. Besides, 1,25VitD3 treatment significantly increased FOXP3/ROR-γt mRNA expression from baseline in PBMCs of the fetal loss group compared to that of the control group (p = 0.01). The 1,25VitD3 also increased GITR gene expression (p = 0.017) in PBMCs of URPL women compared to the controls. Conclusion: Vitamin D deficiency may be a contributor to recurrent pregnancy loss and suggests that the supplementation of women with Vitamin D pre-pregnancy may be protective against URPL via affecting Tregs signature genes, FOXP3 and GITR.

[Acupuncture ameliorates negative emotion in PCOS patients: a randomized controlled trial].

OBJECTIVE: To evaluate the effectiveness and possible mechanism of acupuncture treatment for negative emotion in patients with polycystic ovary syndrome (PCOS). METHODS: A total of 40 PCOS patients were randomly divided into an observation group and a control group, 20 cases in each one. Both groups received lifestyle interventions (exercise and diet guidance) on the 5th day of menstruation. On the basis of above treatment, the patients in the observation group received acupuncture at Guanyuan (CV 4), Zhongwan (CV 12), Guilai (ST 29), Futu (ST 32), Liangqiu (ST 34), Sanyinjiao (SP 6), Zusanli (ST 36), Hegu (LI 4), Shenmen (HT 7), Baihui (GV 20) as the main acupoints, and connected the electroacupuncture (continuous wave, 2 Hz, 30 min), once every other day, 3 times a week. The treatment for 1 month was as one course and 4 courses were required totally in both groups. Before and after treatment, the body mass index (BMI), ferriman-gallway (F-G) score, self-rating anxiety scale (SAS) score, self-rating depression scale (SDS) score, PCOS health-related quality of life questionnaire (PCOSQ) score were observed, meanwhile, serum sex hormone, including follicle-stimulating hormone (FSH), luteinizing hormone (LH), estrogen (E2), progestin (P), prolactin (PRL), testosterone (T), sex hormone-binding globulin (SHBG) and free androgen index (FAI) levels, and serumß-endorphin levels were detected. RESULTS: Compared with before treatment, the BMI, F-G score, SAS score, SDS score and serum FAI level were decreased and the PCOSQ score and the levels of serum SHBG andß-endorphin were increased in the observation group after treatment (all P<0.05). Compared with before treatment, the SDS score was decreased in the control group after treatment (P<0.05). Compared with the control group, the F-G score, SDS score, SAS score, and serum FAI level were lower, and the PCOSQ score and serumß-endorphin level were higher in the observation group after treatment (all P<0.05). CONCLUSION: Applying acupuncture to the treatment of patients with PCOS can effectively relieve anxiety and depression, and the mechanism may be related to the regulation on the levels of serumß-endorphin and androgen.

Clinical effects of Shou-Wu Jiang-Qi Decoction combined acupuncture on the treatment of Polycystic Ovarian Syndrome with kidney deficiency, phlegm and blood stasisness: Study protocol clinical trial (SPIRIT Compliant).

BACKGROUND: Polycystic ovary syndrome (PCOS) is a female endocrine disease with a high incidence. At present, drug treatment is still the main therapeutic strategy for PCOS. Traditional Chinese medicine has a long history in the treatment of menstrual disorders. Shouwu Jiangqi Decoction (SWJQD) is a traditional herbal medicine prescribed in a clinical setting as a remedy for PCOS. Acupuncture also plays an important role in regulating the menstrual cycle and treating PCOS. This study aims to examine the efficacy and safety of the combination of SWJQD and acupuncture in the treatment of PCOS. METHODS: This randomized controlled trial will be conducted with a total of 81 participants diagnosed with PCOS. The participants will be randomly divided into 3 treatment groups: group A will receive SWJQD combined with acupuncture; group B, SWJQD combined with sham acupuncture; and group C, metformin. Each treatment will last 3 months. The primary outcomes include the Homeostatic Model Assessment of Insulin Resistance (HOMA-IR) index and the Oral Glucose Tolerance Test. The secondary outcome measures include sex hormone levels, body mass index, ovulation rate, clinical pregnancy rate, and complete genome sequencing data. Adverse events will be recorded during the intervention and follow-up. RESULTS: This study will investigate whether the combination of SWJQD and acupuncture can alleviate the clinical symptoms and improve insulin resistance in patients with PCOS. The results of this study are expected to provide clinical evidence for the application of the combination of SWJQD and acupuncture in patients with PCOS.

Effect of Combined Prenatal and Adult Benzophenone-3 Dermal Exposure on Factors Regulating Neurodegenerative Processes, Blood Hormone Levels, and Hematological Parameters in Female Rats.

Benzophenone-3 (BP-3), the most widely used UV chemical filter, is absorbed well through the skin and gastrointestinal tract and can affect some body functions, including the survival of nerve cells. Previously, we showed that BP-3 evoked a neurotoxic effect in male rats, but since the effects of this compound are known to depend on gender, the aim of the present study was to show the concentration and potential neurotoxic action of this compound in the female rat brain. BP-3 was administered dermally to female rats during pregnancy, and then in the 7th and 8th weeks of age to their female offspring. The effect of BP-3 exposure on short-term and spatial memory, its concentrations in blood, the liver, the frontal cortex, and the hippocampus, and the effect on selected markers of brain damage were determined. Also, the impact of BP-3 on sex and thyroid hormone levels in blood and hematological parameters was examined. It has been found that this compound was present in blood and brain structures in females at a lower concentration than in males. BP-3 in both examined brain structures increased extracellular glutamate concentration and enhanced lipid peroxidation, but did not induce the apoptotic process. The tested compound also evoked hyperthyroidism and decreased the blood progesterone level and the number of erythrocytes. The presented data indicated that, after the same exposure to BP-3, this compound was at a lower concentration in the female brain than in that of the males. Although BP-3 did not induce apoptosis in the hippocampus and frontal cortex, the increased extracellular glutamate concentration and lipid peroxidation, as well as impaired spatial memory, suggested that this compound also had adverse effects in the female brain yet was weaker than in males. In contrast to the weaker effects of the BP-3 on females than the brain of males, this compound affected the endocrine system and evoked a disturbance in hematological parameters more strongly than in male rats.

A combination of Semen Cuscutae and Fructus Lycii improves testicular cell proliferation and inhibits their apoptosis in rats with spermatogenic dysfunction by regulating the SCF/c-kit--PI3K--Bcl-2 pathway.

ETHNOPHARMACOLOGICAL RELEVANCE: Semen Cuscutae is the seed of Cuscuta japonica Choisy, and Fructus Lycii is the mature fruit of Lycium barbarum L. (Solanaceae). Semen Cuscutae and Fructus Lycii (SC-FL) are well-known Chinese medicine which have been used to tonify the kidney and replenish the essence for thousands of years. Chinese physicians prefer to prescribe them for treating male infertility. Recent studies have found that SC-FL repair spermatogenic dysfunction, however, the therapeutic mechanism has yet to be clearly elucidated. AIM OF THE STUDY: This study aimed at evaluating the therapeutic effect of SC-FL in glucosides of Tripterygium wilfordii Hook. f (GTW)-induced dyszoospermia rats and elucidating the underlying molecular mechanism. MATERIALS AND METHODS: Seventy-eight Sprague-Dauley (SD) rats were randomly divided into five groups: normal control (treated with saline), GTW (treated with saline), GTW + levocarnitine (treated with levocarnitine), GTW + SCFL (treated with SC-FL), and LY (LY294002, the PI3K inhibitor) +SCFL (treated with SC-FL). GTW (40 mg/kg/d) was intragastrically administered for 4 weeks to establish dyszoospermia model. From the start of the study, LY was additionally injected into the tail vein of rats of the LY + SCFL group once a week. After 8 weeks, semen quality and organ coefficient were determined and sex hormone, inhibin B, and epididymal carnitine levels were measured. Testicular tissue and its ultrastructure were observed using H&E (hematoxylin-eosin) staining and electron microscopy. Immunohistochemistry, western blotting, and quantitative reverse transcription polymerase chain reaction (qRT-PCR) were used to determine the protein and mRNA expression of SCF, c-kit, PI3K, p-Akt, Bad, Bcl-2, and Bax in rat testis. RESULTS: Compared with the GTW group, semen quality, the organ coefficient, follicle stimulating hormone (FSH), luteinizing hormone (LH), prolactin (PRL), and epididymal carnitine levels were significantly improved in the GTW + SCFL group (P < 0.05 or P < 0.01). Histomorphology and testicular ultrastructural evaluation showed that in the GTW + SCFL group, the structure and arrangement of seminiferous tubules were better, the amount of spermatogenic cells increased significantly, the morphology of spermatogenic cells improved, and the mitochondria increased, compared to those in the GTW group. Immunohistochemistry, western blotting, and qRT-PCR results showed that compared with the GTW group, the expression of SCF, c-kit, PI3K, p-Akt, and Bcl-2 in the GTW + SCFL group was increased, while that of Bax and Bad was decreased. The expression of p-Akt and Bcl-2 decreased, while that of Bad and Bax increased in the LY + SCFL group compared with the SCFL group. CONCLUSION: SC-FL can effectively inhibit spermatogenic cell apoptosis and promote their proliferation, and the mechanism may be related to the regulation of the SCF/c-kit--PI3K--Bcl-2 pathway.
