Abstract
CONTEXT Polycystic ovary syndrome (PCOS) is a prevalent hormonal imbalance that predominantly affects women in their reproductive years. Previous studies have yielded conflicting conclusions. OBJECTIVE This is an updated meta-analysis aiming to explore the connection between flavonoid supplementation and PCOS. DATA SOURCES Seven databases were searched: Cochrane Library, PubMed, Web of Science, Embase, Wanfang, China Science and Technology Journal, and China National Knowledge Infrastructure, spanning from their inception to April 15, 2024. DATA EXTRACTION Two authors independently searched the databases using the search terms. DATA ANALYSIS Following strict inclusion criteria, 8 papers were ultimately included. This updated meta-analysis suggests that flavonoid supplementation could enhance follicular development, promote the proliferation and differentiation of follicular granulosa cells, elevate estradiol levels, and mitigate testosterone, C-reactive protein, and ovarian index levels. CONCLUSION This analysis suggests that dietary flavonoids could potentially alleviate symptoms associated with PCOS. SYSTEMATIC REVIEW REGISTRATION PROSPERO registration no. CRD42022382912.

Abstract
PURPOSE Polycystic ovary syndrome (PCOS) is a common endocrine disorder that affects women of reproductive age. It is characterized by irregular menstrual cycles, hyperandrogenism, and polycystic ovaries. The syndrome's etiology is multifactorial, involving genetic, hormonal, metabolic, and environmental factors. Given its diverse effects, managing PCOS requires a comprehensive approach. METHODS This study employed a Sprague-Dawley rat model to investigate the effects of ellagic acid on polycystic ovary syndrome (PCOS). Forty adult female rats were randomly divided into four groups: a control group, a healthy group receiving ellagic acid (200 mg/kg), a PCOS group, and an ellagic acid + PCOS group. PCOS was induced in the relevant groups through subcutaneous injection of estradiol valerate (2 mg/kg), and ellagic acid was administered via subcutaneous injections for 14 days. Blood samples were collected for hormone analysis using the ELISA method, and ovarian tissues were processed for histological examination. RESULT Ellagic acid treatment showed reduced LH levels and restoration of follicular development, particularly primordial and graafian follicles, along with modulation of miRNA-21 expression. Moreover, ellagic acid exhibited positive effects on ovarian morphology, including decreased theca layer thickness, increased oocyte diameter, and improvements in antral and preovulatory follicles. This suggests ellagic acid's potential in addressing follicular development and oocyte quality in PCOS. CONCLUSIONS These findings suggest ellagic acid as a potential complementary approach in PCOS management. While the study is promising, further research, including clinical trials, is required to elucidate ellagic acid's mechanisms and clinical efficacy in human PCOS subjects.

Prostaglandins Other Lipid Mediat 2024; 170:106801. [PMID: 37984794 DOI: 10.1016/j.prostaglandins.2023.106801] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/09/2023] [Revised: 11/10/2023] [Accepted: 11/15/2023] [Indexed: 11/22/2023]
Abstract
OBJECTIVE This study was designed to investigate the therapeutic effect of Cangfu Daotan Decoction (CDD) combined with drospirenone and ethinylestradiol tablets (II) on patients with polycystic ovary syndrome (PCOS). METHODS Patients with PCOS were gathered from September 2020 to September 2022 and divided into the experimental group (n = 36), treated with CDD combined with drospirenone and ethinylestradiol tablets (II), and the control group (n = 41), received only drospirenone and ethinylestradiol tablets (II). Levels of sex hormone, obesity, blood glucose, blood lipid were detected and compared between the two groups pre- and post-treatment. The treatment efficacy, Traditional Chinese Medicine (TCM) syndrome score, adverse drug reactions, and pregnancy rate were compared as well. RESULTS After treatment, the experimental group had a higher treatment efficacy (94.44% vs 73.17%, P < 0.05) and a higher pregnancy rate (44.44% vs 21.95%, P < 0.05) than the control group, but the difference in the incidence of adverse drug reactions was not statistically significant (P > 0.05). Compared with control group, TCM syndrome score and levels of fasting blood glucose, fasting insulin, homeostasis model assessment of insulin resistance (HOMA-IR), and waist circumference of the experimental group after treatment displayed remarkable reduction (P < 0.05), while the levels of estradiol (E2) and high-density lipoprotein cholesterol (HDL-C) showed a remarkable increase (P < 0.05). CONCLUSION CDD in combination with drospirenone and ethinylestradiol tablets (II) may be effective in treating PCOS by improving obesity, glucose metabolism and lipid metabolism with no serious adverse events, making it a feasible clinical practice option.

Peng MF, Tian S, Song YG, Li CX, Miao MS, Ren Z, Li M. 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. JOURNAL OF ETHNOPHARMACOLOGY 2021; 273:113947. [PMID: 33617969 DOI: 10.1016/j.jep.2021.113947] [Citation(s) in RCA: 27] [Impact Index Per Article: 9.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/20/2020] [Revised: 02/09/2021] [Accepted: 02/14/2021] [Indexed: 06/12/2023]
Abstract
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.

Morphologie 2021; 106:145-154. [PMID: 34023214 DOI: 10.1016/j.morpho.2021.04.004] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/08/2021] [Revised: 04/28/2021] [Accepted: 04/30/2021] [Indexed: 11/16/2022]
Abstract
BACKGROUND Polycystic ovary syndrome (PCOS) is a multifactorial hormonal disorder accompanied by impairment of endometrial function and structure. Pomegranate is recognized for its role in normalizing the female sex hormones in PCOS with little known about its effect on the accompanying endometrial histological alterations. AIM OF THE WORK To assess the possible ameliorative role of pomegranate juice extract (PJE) on endometrial injury in a rat model of PCOS. MATERIAL AND METHODS Forty adult albino rats were equally divided into 4 groups; control, PJE-treated (400mg/kg/day for 3 weeks), letrozole-treated (PCOS) (1mg/kg/day for 3 weeks), and PJE & PCOS groups. Serum Follicle-stimulating hormone (FSH), Luteinizing hormone (LH), testosterone, estradiol, and tissue malondialdehyde (MDA) were assayed. Uterine samples were processed for histological staining with hematoxylin & eosin and Masson's trichrome stains, Ki67 and androgen receptor immunohistochemical staining, and scanning electron microscopy. RESULTS PCOS group revealed a significant increase in serum FSH, LH, testosterone, estradiol, and tissue MDA. Uterine sections depicted various histological alterations in the endometrium with signs of inflammation. A significant increase in the endometrial collagen fiber content, as well as a significant upregulation in Ki67 and androgen receptor immunohistochemical expression were detected. Scanning electron microscopy showed a significant decrease in the mean number of pinopodes. Concomitant administration of PJE efficiently restored the studied biochemical, histological, and immunohistochemical parameters. CONCLUSION PJE ameliorated PCOS accompanying endometrial histological alterations through its antioxidant, anti-inflammatory, anti-fibrotic, anti-proliferative, and anti-androgenic effects most probably due to its polyphenols content.

Abstract
The study aimed to explore the efficacy and safety of Kunxian Capsule (KXC) in the treatment of rheumatoid arthritis (RA). The randomized controlled trials (RCTs) comparing the effects of KXC in patients with RA were included in this study. Weighted mean differences (MDs) were calculated for net changes by employing Review Manager meta-analysis software. Nine RCTs were included in the systematic review with a total of 747 patients. The overall effects showed that KXC alone or combined with disease-modifying antirheumatic and drugs decreased tender joint counts (P=0.02, MD = −1.07, 95% CI: −1.95 to −0.18), shortened duration of morning stiffness (P < 0.0001, MD = −9.01, 95% CI: −13.08 to −4.93), lowered erythrocyte sedimentation rate (P < 0.00001, MD = −5.27, 95% CI: −6.78 to −3.77), and reduced C-reactive protein (P < 0.0001, MD = −5.04, 95% CI: −7.28 to −2.80). The most common adverse events were gastrointestinal disturbances and abnormal liver function. These results suggest that KXC is likely to be a more effective and safe candidate for treating RA compared with conventional therapies.

Abstract
OBJECTIVE Research has shown that polycystic ovary syndrome (PCOS) is a common cause of infertility in women. The drugs used to treat PCOS tend to manage the symptoms rather than cure the disease. Furthermore, these drugs have severe side-effects and influence the quality of life for the patients. There is therefore a need for natural medicine that can effectively treat PCOS without side-effects. METHOD PCOS was induced in adult female Wistar rats by daily oral administration of letrozole (1 mg/kg) for 21 days. From day 22 until the end of the experiment (day 36), these rats were given a daily oral dose of either Prunus dulcis (walnut) or Salvia hispenica (chia seed) alone, or in combination. Animals were subsequently examined for morphological, biochemical, and histopathological changes. RESULT When compared with the control and standard groups, rats who had consumed P. dulcis and S. hispenica, either as individual agents or in combination, had significantly lower body and ovarian weights, and hormone concentrations were maintained at healthy levels. The presence of polyphenolic compounds in these substances induced ovulation in the PCOS model animals. CONCLUSION This study demonstrated that animals fed with P. dulcis and S. hispenica either individually or in combination were able to overcome infertility. Hormone levels and metabolism were restored in these animals. Therefore, P. dulcis and S. hispenica can be used as therapeutic agents to treat patients who are infertile due to suboptimal oocyte competence and anovulation.

Genomics 2020; 112:2695-2702. [PMID: 32145379 DOI: 10.1016/j.ygeno.2020.03.002] [Citation(s) in RCA: 25] [Impact Index Per Article: 6.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/21/2019] [Revised: 02/05/2020] [Accepted: 03/03/2020] [Indexed: 11/28/2022]
Abstract
The protein-coding genes and pseudogenes of Cuscuta australis had the diverse contribution to the formation and evolution of parasitism. The codon usage pattern analysis of these two type genes could be used to understand the gene transcription and translation. In this study, we systematically analyzed the codon usage patterns of protein-coding sequences and pseudogenes sequences in C. australis. The results showed that the high frequency codons of protein coding sequences and pseudogenes had the same A/U bias in the third position. However, these two sequences had converse bias at the third base in optimal codons: the protein coding sequences preferred G/C-ending codons while pseudogene sequences preferred A/U-ending codons. Neutrality plot and effective number of codons plot revealed that natural selection played a more important role than mutation pressure in two sequences codon usage bias. Furthermore, the gene expression level had a significant positive correlation with codon usage bias in C. australis. Highly-expressed protein coding genes exhibited a higher codon bias than lowly-expressed genes. Meanwhile, the high-expression genes tended to use G/C-ending synonymous codons. This result further verified the optimal codons usage bias and its correlation with the gene expression in C. australis.
