ABSTRACT

Introdução: A síndrome dos ovários policísticos (SOP) consiste em uma desordem de origem endocrinológica de grande prevalência nas mulheres em idade fértil, sendo acometidas por ela aproximadamente de 6 a 16% da população feminina - em consonância com diversos critérios diagnósticos 1-4. Essa síndrome é associada ao hiperandrogenismo e à resistência insulínica (RI), com manifestações clínicas relacionadas a alterações reprodutivas 4, desenvolvimento de diabetes mellitus (DM2) e obesidade. Esta pesquisa objetiva compreender o perfil das mulheres com DM 2 antes dos 35 anos e os fatores que podem levar a esta condição. Metodologia: Este estudo se deu por meio de inquérito on-line feito a mulheres diagnosticadas com SOP, e com menos de 35 anos de idade. Foi desenvolvido de maneira virtualizada via plataforma GoogleForms® em função da pandemia do COVID-19. Tratou-se de um levantamento sobre presença de fatores de risco para DM 2, como sobrepeso e alimentação, sedentarismo e qualidade do sono; em grupos de mulheres com SOP diabéticas e não diabéticas, para efeito de comparação. Resultados e discussão: Um total de 198 mulheres responderam ao questionário, sendo divididas em Diabéticas (DM) e não diabéticas (NDM). O grupo DM foi o que mais apresentou IMC elevado (acima de 30), e o que mais se declarou seguir orientações nutricionais. Atividade física não diferenciou entre os grupos. O grupo DM foi o que declarou dormir mais tarde (pós 23:00) quando comparado com o grupo NDM. O sobrepeso indica ser um fator importante para o advento da DM 2 neste grupo, sendo as orientações nutricionais não tão efetivas, devido muito a dificuldade de aderir às orientações. O hábito de dormir tarde implica em alterações que levam a aumento da RI via estresse oxidativo, contribuindo para obesidade e DM 2. Conclusões: A obesidade é um fator decisivo para a precocidade da DM 2 em mulheres com SOP, e sua condição é multifatorial, associada a seguimento de orientações nutricionais, atividade física e qualidade do sono. O evitar da precocidade da DM 2 neste grupo passa por esta compreensão.


Introduction: Polycystic ovary syndrome (PCOS) is an endocrinological disorder with high prevalence in women of childbearing age, affected by approximately 6 to 16% of the female population - in line with several diagnostic criteria 1-4. This syndrome is associated with hyperandrogenism and insulin resistance (IR), with clinical manifestations related to reproductive changes 4, development of diabetes mellitus (DM2) and obesity. This research aims to understand the profile of women with DM 2 before the age of 35 and the factors that can lead to this condition. Methodology: This study was carried out through an online survey made to women diagnosed with PCOS, and under 35 years of age. It was developed in a virtualized way via the GoogleForms® platform due to the COVID-19 pandemic. This was a survey on the presence of risk factors for DM 2, such as overweight and diet, sedentary lifestyle and sleep quality; in groups of women with diabetic and non-diabetic PCOS for comparison purposes. Results and discussion: A total of 198 women answered the questionnaire, divided into Diabetic (DM) and non-diabetic (NDM). The DM group was the one with the highest BMI (above 30), and the one that most declared to follow nutritional guidelines. Physical activity did not differ between groups. The DM group was the one who reported sleeping later (after 11 pm) when compared to the NDM group. Overweight is an important factor for the advent of DM 2 in this group, and nutritional guidelines are not so effective, due to the difficulty in adhering to the guidelines. The habit of sleeping late implies changes that lead to increased IR via oxidative stress, contributing to obesity and DM 2. Conclusions: Obesity is a decisive factor for the precocity of DM 2 in women with PCOS, and its condition is multifactorial, associated with following nutritional guidelines, physical activity and sleep quality. Avoiding the precocity of DM 2 in this group involves this understanding.

ABSTRACT

OBJECTIVE To study the improvement effects of poria acid on insulin resistance in rats with polycystic ovary syndrome (PCOS) and its mechanism. METHODS One hundred and twenty-six female rats were randomly separated into blank group, PCOS group, poria acid low-dose group (8.33 mg/kg), pachymic acid high-dose group (33.32 mg/kg), ethinylestradiol cyproterone group (positive control group, 0.34 mg/kg), recombinant rat high mobility group protein B1 protein (rHMGB1) group (8 μg/kg), and poria acid high dose+rHMGB1 group (33.32 mg/kg poria acid+8 μg/kg rHMGB1), with 18 rats in each group. Except for the blank group, the rats in all other groups were given Letrozole suspension intragastrically to construct the PCOS model. After successful modeling, administration was performed once a day for 4 weeks. After medication, the fasting blood glucose and fasting insulin levels, and insulin resistance index (HOMA-IR) were measured in rats; the levels of follicle-stimulating hormone (FSH), luteinizing hormone (LH) and testosterone (T) in rat serum, and the levels of interleukin-1β (IL-1β) and tumor necrosis factor- α (TNF- α) in ovarian tissue were detected; ovarian coefficients of rats were calculated; the pathological changes of ovarian tissue were observed; the expressions of HMGB1, receptor for advanced glycosylation elaine_ tanghong@sina.com end product (RAGE) and phosphorylated nuclear factor κB p65 (p-NF-κB p65) proteins were determined in ovarian tissue of rats. RESULTS Compared with the blank group, the pathological injury of ovarian tissue of rats in the PCOS group was serious, the levels of fasting blood glucose and fasting insulin, HOMA-IR and ovarian coefficient were increased, the levels of serum LH and T were increased, while the levels of FSH were decreased; the levels of IL-1β and TNF-α, the expressions of HMGB1, RAGE and p-NF-κB p65 protein in ovarian tissue were increased, with statistical significance (P<0.05). Compared with the PCOS group, pathological damage of ovarian tissue was reduced in poria acid low-dose and high-dose groups and ethinylestradiol cyproterone group, and fasting blood glucose, fasting insulin levels, HOMA-IR and ovarian coefficient were decreased; serum LH and T levels were decreased, while FSH levels were increased; the levels of IL-1β and TNF-α and the expressions of HMGB1, RAGE and p-NF-κB p65 protein in ovarian tissue were decreased, with statistical significance (P<0.05). The trend of corresponding indexes in rHMGB1 group was opposite to the above (P<0.05). Compared with poria acid high-dose group, the changes of the above indexes were reversed significantly in poria acid high-dose+rHMGB1 group (P<0.05). CONCLUSIONS Poria acid may improve insulin resistance and inhibit inflammatory reaction in PCOS rats by inhibiting HMGB1/ RAGE pathway.

ABSTRACT

O sangramento uterino anormal é diagnóstico sindrômico comum no consultório do ginecologista e pode comprometer substancialmente a qualidade de vida. O objetivo no diagnóstico de sangramento uterino anormal é distinguir pacientes com causas estruturais (anatômicas), como pólipo, adenomiose, leiomioma, malignidade e hiperplasia, de pacientes que apresentam anatomia normal, nas quais o sangramento pode ser devido a alteração dos mecanismos de coagulação, distúrbios ovulatórios, distúrbios primários do endométrio, iatrogenia, ou ter outra causa não classificada. O diagnóstico se inicia a partir de anamnese detalhada e exame físico geral e ginecológico completos, seguidos da solicitação de exames complementares (laboratoriais e de imagem), conforme indicado. O exame de imagem de primeira linha para identificação das causas estruturais inclui a ultrassonografia pélvica. Histerossonografia, histeroscopia, ressonância magnética e amostragem endometrial para exame de anatomia patológica são opções que podem ser incluídas no diagnóstico a depender da necessidade. O objetivo deste artigo é apresentar a relevância dos exames de imagem na investigação das causas de sangramento uterino anormal.


Abnormal uterine bleeding is one of the commonest presenting complaints encountered in a gynecologist's office and may substantially affect quality of life. The aim in the diagnosis of abnormal uterine bleeding is to distinguish women with anatomic causes such as polyp, adenomyosis, leiomyoma, malignancy and hyperplasia from women with normal anatomy where the cause may be coagulopathy, ovulatory disorders, endometrial, iatrogenic and not otherwise classified. Diagnosis begins with a thorough history and physical examination followed by appropriate laboratory and imaging tests as indicated. The primary imaging test for the identification of anatomic causes include ultrasonography. Saline infusion sonohysterography, magnetic resonance, hysteroscopy, endometrial sampling are options that can be included in the diagnosis depending on the need. The aim of this article is to present the relevance of imaging exams in the investigation of the causes of abnormal uterine bleeding.

ABSTRACT

ABSTRACT Objective: To evaluate the effect of metabolic syndrome (MetS) diagnosis on oocyte quality and pregnancy outcomes in infertile women with polycystic ovary syndrome (PCOS) who undergoing antagonist-controlled ovarian stimulation (COS) and in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) cycles. Subject and methods: This prospective cohort study was conducted from November 2019 to November 2020 across two university-affiliated infertility centers in Iran. The PCOS diagnosis was defined according to the Rotterdam criteria. The patients prior to IVF/ICSI cycles were evaluated for MetS diagnosis. MetS was detected according to the National Cholesterol Education Program/Adult Treatment Panel III with the presence of at least three or more of the specific clinical criteria. The cycle outcomes were compared between MetS and non-MetS groups. Results: Overall, 68 eligible infertile PCOS patients with MetS diagnosis and 126 without MetS participated. The MetS diagnosis was associated with the increased requirement of gonadotropins and the COS duration significantly (P = 0.001). Although the total numbers of retrieved and MII oocytes, obtained and top-quality embryos as well as clinical pregnancy and live birth rates in the MetS group were lower than those of in the non-MetS group, the differences were not statistically significant (P > 0.05). In follow-up of the obstetrics complications, the rate of preeclampsia was significantly higher in patients with MetS (P = 0.02). Conclusion: MetS diagnosis in PCOS patients was associated with non-significant poor COS and pregnancy outcome. Further studies with larger sample sizes are recommended to clarify the risk of MetS in patients undergoing ART cycles.

ABSTRACT

Polycystic Ovary Syndrome (PCOS) is one of the most prevalent endocrine disorder in women of reproductive age characterized by hyperandrogenism (HA). Current treatment options for PCOS are either with adverse effects or ineffective. Saptasaram kashayam (SK), an ayurvedic formulation is often been a safe traditional alternative medicine to improve the PCOS symptoms as well as its pathological development. However, its principle phytoconstituents or underlying mechanisms have not been investigated. In order to achieve this, the current study systematically utilized computational tools, network pharmacology approaches and molecular docking studies. All identified phytoconstituents of SK were screened by QikProp ADME prediction and 47 were selected based on oral bioavailability and drug likeliness scores. Their 3D structures were submitted to three online target fishing webservers PharmMapper, ChemMapper and Swiss Target Prediction which produced 1084 biological targets for SK comprehensively. 350 known PCOS therapeutic targets were retreived as common targets from three different interrogative disease centric bioinformatic platforms DisGeNET, OMIM and GeneCards. Intersection of 1084 biological targets of SK and 350 PCOS therapeutic targets produced, 88 potential therapeutic targets of SK against PCOS. STRING PPI and Compound-Target-Pathway networks were constructed and analysed using Cytoscape software. GO & KEGG pathway enrichment analysis was performed using DAVID database. 15 PCOS therapeutic target proteins were short listed from network analysis report- PIK3CA, PDPK1, AKT1, PIK3R1, STAT3, MAPK1, MAPK3, EGFR, AR, ESR1, ESR2, SHGB, NOS3, F2 & CREBBP. Targets that were likely to be inhibited/modulated by SK for treatment of PCOS were docked against the screened phytoconstituents and their respective standard inhibitors using GLIDE-SP of Schrodinger suite, Maestro version- 13.0. Results showed that Quercetin, Catechin, Boeravinone J, Genistein, Protocatechuic Acid, Gentisic Acid, Xanthoarnol, Luteolin, Boeravinone F, Tyrosine, Kaempferol, Dalbergioidin, etc exhibited good binding affinities when compared to standard drugs and might be responsible for synergistic/additive protective effect of SK against PCOS. Meanwhile PI3K-Akt signaling pathway, Prolactin signaling pathway, AGE-RAG diabetic complications, HIF-1 signaling pathway and Estrogen signaling pathway were found to be involving the hub genes of interest and in this way, they might be intervened during treatment of PCOS by SK. Present study succeeded in identifying the drug like principle phytoconstituents, probable PCOS therapeutic targets and the underlying molecular mechanism of SK apart from providing reliable evidence for therapeutic potential of SK against PCOS. However further validation by in vitro and in vivo investigations is necessary.

ABSTRACT

Background & objectives: Studies have shown that insulin resistance and hyperinsulinaemia play a major role in the pathogenesis of polycystic ovary syndrome (PCOS). Therefore, the use of insulin sensitizing drugs in the treatment of PCOS has attracted the attention of medicine and researchers. The aim of this study was to investigate the effects of sitaformin (sitagliptin/metformin) and metformin on the quality of oocyte and embryo in classic PCOS patients undergoing intracytoplasmic sperm injection (ICSI). Methods: Sixty patients of PCOS (25-35 yr) were randomly allocated into three groups (n=20, each group): a metformin-treated group (administered metformin 500 mg twice daily), a sitaformin-treated group (administered sitaformin 50/500 mg twice daily) and a placebo group. Participants in all the groups received the drug two months prior to the start of the ovulation cycle and treatment continued until the day of the oocyte aspiration. Results: Serum insulin and total testosterone levels decreaseed significantly after treatment in both the treatment groups as compared to the placebo (P<0.05). A significant decrease in the number of immature oocytes [MI + germinal vesicle (GV) stage] was observed in metformin and sitaformin groups as compared to the placebo. In addition, sitaformin group when compared to the metformin group showed a significant decrease in the number of immature oocytes (P<0.05). The number of mature and normal MII oocytes increased significantly in both the treatment groups compared to the placebo group (P<0.05). The number of mature and normal oocytes increased in sitaformin group in comparison to the metformin group, but the difference was not significant. There was a significant increase in the number of grade I embryos, fertilization and cleavage rates in the sitaformin group compared to the other groups (P<0.05). Interpretation & conclusions: This is the first study to compare the impact of sitaformin with metformin on oocyte and embryo quality in women with PCOS undergoing a gonadotropin-releasing hormone (GnRH) antagonist cycle. In conclusion, sitaformin can be more effective in decreasing immature oocytes and increasing the quality of embryos than the use of metformin.

ABSTRACT

SUMMARY OBJECTIVE: The objective of this study was to investigate the breast densities and Breast Imaging-Reporting and Data System scores of patients with polycystic ovary syndrome and normoovulatory women and to determine whether these patients constitute a high-risk population for breast cancer. METHODS: This retrospective case-control study was conducted at our institution between January 2022 and December 2022, involving patients diagnosed with polycystic ovary syndrome. Menstrual periods, hyperandrogenemic findings, and ultrasound reports of the patients were retrieved from our hospital's database. Patients who met at least two of the Rotterdam criteria were included in the polycystic ovary syndrome group. A total of 70 premenopausal patients over the age of 40 years, diagnosed with polycystic ovary syndrome, and 70 normoovulatory women, matched for age and body mass index, were included in the study. The two groups were compared regarding age at menarche, menstrual pattern, gravida, parity, levels of follicle-stimulating hormone, luteinizing hormone, and estradiol, endometrial thickness, breast density category, and Breast Imaging-Reporting and Data System classifications. RESULTS: Patients in the polycystic ovary syndrome group had a higher age at menarche (12.7 vs. 12.3, p=0.006). There was no difference between the gonadotropin levels in both groups. However, the estradiol level was higher in the polycystic ovary syndrome group (p<0.001). There was no statistically significant difference between the two groups in terms of breast density and Breast Imaging-Reporting and Data System scores (p=0.319 and p=0.650, respectively). CONCLUSION: Although we can conclude that the risk of breast malignancy is not increased in patients with polycystic ovary syndrome, the impact of the complex hormonal status of polycystic ovary syndrome on breast cancer remains unclear in the literature.

ABSTRACT

SUMMARY OBJECTIVE: The aim of this study was to compare the distribution of fat tissue in non-obese women with polycystic ovary syndrome and those without the syndrome using dual-energy radiological densitometry. METHODS: This was a case-control study in which we enrolled women aged 14-39 years with polycystic ovary syndrome according to the Rotterdam criteria with a body mass index between 18.5 and 30 kg/m2. The control group comprised women with the same profile, but without polycystic ovary syndrome. Patients were treated at the Endocrinological Gynecology Outpatient Clinic of the Department of Obstetrics and Gynecology of the Irmandade da Santa Casa de Misericórdia de São Paulo between 2019 and 2022. Anthropometric measurements were taken and the assessment of body composition was performed using dual-energy radiological densitometry. RESULTS: The sample comprised 57 women: 37 in the polycystic ovary syndrome group and 20 in the control group. The mean age of the polycystic ovary syndrome group was 24.9 years (±6.9) with a mean body mass index of 60.8 kg/m2 (±8.5), and for the control group, it was 24.2 years (±6.9) with a mean body mass index of 58 kg/m2 (±8.4). Body composition was evaluated using dual-energy radiological densitometry and showed a higher value of trunk fat in the polycystic ovary syndrome group (44.1%, ±9.0) compared to the control group (35.2%, ±11.4), which was statistically significant (p=0.002). CONCLUSION: Our study showed that non-obese polycystic ovary syndrome patients have a higher concentration of abdominal fat, which is a risk factor for increased cardiovascular risk and insulin resistance.

ABSTRACT

Abstract PCOS is an endocrine disorder characterized by chronic anovulation, hyperandrogenism, and polycystic ovaries. Its etiology is uncertain. It is debated whether BPA would be a component of the environmental factor in the etiology of PCOS. Contamination by BPA can occur from food packaging (exposure during the diet) and through skin absorption and/or inhalation. It can be transferred to the fetus via the placenta or to the infant via breast milk, and it can be found in follicular fluid, fetal serum, and amniotic fluid. The phenolic structure of BPA allows it to interact with Estrogen Receptors (ERs) through genomic signaling, in which BPA binds to nuclear ERα or Erβ, or through nongenomic signaling by binding to membrane ERs, prompting a rapid and intense response. With daily and constant exposure, BPA's tendency to bioaccumulate and its ability to activate nongenomic signaling pathways can alter women's metabolic and reproductive function, leading to hyperandrogenism, insulin resistance, obesity, atherogenic dyslipidemia, chronic inflammatory state, and anovulation and favoring PCOS. The harmful changes caused by BPA can be passed on to future generations without the need for additional exposure because of epigenetic modifications. Not only high BPA levels can produce harmful effects, but at low levels, BPA may be harmful when exposure occurs during the most vulnerable periods, such as the fetal and neonatal periods, as well as during the prepubertal age causing an early accumulation of BPA in the body. Learning how BPA participates in the pathogenesis of PCOS poses a challenge and further studies should be conducted.

ABSTRACT

Abstract Introduction Women with Polycystic Ovary Syndrome (PCOS) have a higher prevalence of Nonalcoholic Fatty Liver Disease (NAFLD) than the general population. PCOS and NAFLD have common metabolic risk factors, however, the role of diet in NAFLD development is still uncertain in PCOS women. Objective To evaluate and compare the dietary patterns and nutritional intake in patients with PCOS with and without NAFLD. Method Cross-sectional study that included patients with PCOS diagnosed according to Rotterdam criteria. All participants were submitted to abdominal ultrasound to investigate liver steatosis. Dietary profile was assessed by 24-hour food recall (24hR), and Food Frequency Questionnaire (FFQ). Diet quality was assessed by the Healthy Eating Index (HEI) adapted for the Brazilian population. Physical activity practice was also assessed. Results 87 participants were included (average age 35.2 ± 5.7 years), among whom, 67 (77%) had NAFLD. The group with PCOS and NAFLD presented higher body mass index (BMI) (34.9 ± 4.5 vs. 30.4 ± 4.9 kg/m2; p = 0.001), Waist Circumference (WC) (103 [97‒113] vs. 95 [87.5‒100] cm; p < 0.001) and were considered physically active less frequently than those without NAFLD (34.3% vs. 60%; p = 0.04). Food intake and dietary patterns assessed by 24hR, FFQ and HEI presented no difference between the groups. Conclusions PCOS women with coexistent NAFLD had higher BMI, WC and were less physically active than those without NAFLD. Dietary evaluation showed that PCOS women with NAFLD had no significant difference in macro and micronutrients or food group intake and diet quality in comparison to those without NAFLD.

ABSTRACT

SUMMARY OBJECTIVE: The aim of this study was to analyze the association between lower urinary tract symptoms and polycystic ovary syndrome. METHODS: A total of 180 women were enrolled in this prospective study. Demographic data, body mass index, waist circumference, modified Ferriman-Gallwey scores, biochemical parameters, ultrasonographic findings, and maximum urinary flow rate (Q max) were analyzed. In addition, the Beck Depression Inventory, Beck Anxiety Inventory, and Bristol Female Lower Urinary Tract Symptom Scored Form questionnaires were evaluated for each subject. RESULTS: The mean age of patients was calculated as 23.78±3.04 years, which was similar for both groups (p=0.340). Body mass index, waist circumference, Beck Depression Inventory, Beck Anxiety Inventory, Bristol Female Lower Urinary Tract Symptom Scored Form, and modified Ferriman-Gallwey scores were significantly higher in group 2 (p<<0.001). Hyperandrogenism, lipid profile, and glucose metabolism disorders were more frequent in group 2 (p<<0.05). Bladder capacity (Q max), bladder wall thickness, and post-void residual volume values were similar in both groups (p>>0.05). CONCLUSION: In our study, a close relationship was observed between polycystic ovary syndrome and lower urinary tract symptoms. In this context, we think that a detailed urinary system evaluation of women with polycystic ovary syndrome is extremely important.

ABSTRACT

BACKGROUND@#Polycystic ovary syndrome (PCOS) is the primary cause of anovulatory infertility, bringing serious harm to women's physical and mental health. Acupuncture may be an effective treatment for PCOS. However, systematic reviews (SRs) on the efficacy and safety of acupuncture for PCOS have reported inconsistent results, and the quality of these studies has not been adequately assessed.@*OBJECTIVE@#To summarize and evaluate the current evidence on the efficacy and safety of acupuncture for PCOS, as well as to assess the quality and risks of bias of the available SRs.@*SEARCH STRATEGY@#Nine electronic databases (Cochrane Library, MEDLINE, Embase, PsycINFO, CINAHL, Chinese National Knowledge Infrastructure, Wanfang Data, Chongqing VIP Chinese Science and Technology Periodical Database, and China Biology Medicine disc) were searched from their establishment to July 27, 2022. Based on the principle of combining subject words with text words, the search strategy was constructed around search terms for "acupuncture," "polycystic ovary syndrome," and "systematic review."@*INCLUSION CRITERIA@#SRs of randomized controlled trials that explored the efficacy and (or) safety of acupuncture for treating patients with PCOS were included.@*DATA EXTRACTION AND ANALYSIS@#Two authors independently extracted study data according to a predesigned form. Tools for evaluating the methodological quality, risk of bias, reporting quality, and confidence in study outcomes, including A Measurement Tool to Assess Systematic Reviews 2 (AMSTAR 2), Risk of Bias in Systematic Reviews (ROBIS), Preferred Reporting Items for Systematic Reviews and Meta-analyses for Acupuncture (PRISMA-A), and the Grading of Recommendations Assessment, Development and Evaluation (GRADE), were used to score the included SRs.@*RESULTS@#A total of 885 studies were retrieved, and 11 eligible SRs were finally included in this review. The methodological quality of 2 SRs (18.18%) was low, while the other 9 SRs (81.82%) were scored as extremely low. Four SRs (36.36%) were considered to be of low risk of bias. As for reporting quality, the reporting completeness of 9 SRs (81.82%) was more than 70%. Concerning the confidence in study results, 2 study results were considered to have a high quality of evidence (3.13%), 14 (21.88%) a "moderate" quality, 28 (43.75%) a "low" quality, and 20 (31.24%) considered a "very low" quality. Descriptive analyses suggested that combining acupuncture with other medicines can effectively improve the clinical pregnancy rate (CPR) and ovulation rate, and reduce luteinizing hormone/follicle-stimulating hormone ratio, homeostasis model assessment of insulin resistance, and body mass index (BMI). When compared with medicine alone, acupuncture alone also can improve CPR. Further, when compared with no intervention, acupuncture had a better effect in promoting the recovery of menstrual cycle and reducing BMI. Acupuncture was reported to cause no adverse events or some adverse events without serious harm.@*CONCLUSION@#The efficacy and safety of acupuncture for PCOS remains uncertain due to the limitations and inconsistencies of current evidence. More high-quality studies are needed to support the use of acupuncture in PCOS.

ABSTRACT

Polycystic ovary syndrome (PCOS) is a common reproductive endocrine and metabolic disease, and its pathogenesis is closely related to inflammation, insulin resistance, and metabolic disorders. Bilirubin is the final product of the destruction and degradation of senescent red blood cells in the body. In addition, bilirubin can be not only used to evaluate liver function damage and cytotoxicity, but also can anti-inflammatory, antioxidant, alleviate metabolic disorders, etc. Recently, studies have found a certain correlation between low levels of bilirubin and PCOS: the level of bilirubin in patients with PCOS is low, and the anti-inflammatory and antioxidant properties of bilirubin may play a protective role in the pathogenesis of PCOS.

ABSTRACT

Objective:To investigate the therapeutic effects of Tiaojing Xiaozhi Decoction combined with auricular acupoint embedding acupuncture on polycystic ovary syndrome in obese patients. Methods:A total of 120 obese cases of polycystic ovary syndrome (spleen and kidney deficiency syndrome) treated in Ningbo Municipal Hospital of Traditional Chinese Medicine from July 2020 to June 2021 were included in this study. They were randomly assigned to undergo treatment with either Tiaojing Xiaozhi Decoction (Chinese medicine group, n = 40), auricular acupoint embedding acupuncture (ear acupuncture group, n = 40), or Tiaojing Xiaozhi Decoction and auricular acupoint embedding acupuncture (combined therapy group, n = 40). Traditional Chinese medicine (TCM) syndrome integral, body mass index, waist circumference, hip circumference, waist- to-hip ratio, testosterone, luteinizing hormone, follicle-stimulating hormone, luteinizing hormone/follicle-stimulating hormone, estradiol, prolactin, recombinant human leptin, adiponectin, tumor necrosis factor α, interleukin-6, and clinical efficacy were compared among groups before and after treatment. Results:Total response rate in the combined therapy group was 87.5%, which was slightly but not significantly, higher than 77.5% in the Chinese medicine group and 80.0% in the ear acupuncture group, and there was no significant difference in total response rate among the three groups (all P > 0.05). After treatment, TCM syndrome integral in the combined therapy was (10.40 ± 2.38) points, which was significantly lower than (12.35 ± 3.32) points in the Chinese medicine group and (14.18 ± 3.51) points in the ear acupuncture group ( F = 14.78, P < 0.05). The body mass index, waist circumference, hip circumference, and waist-to-hip ratio in the combined therapy group were superior to those in the Chinese medicine and ear acupuncture groups ( F = 4.11, 18.59, 3.62, 13.33, all P < 0.05). Luteinizing hormone and luteinizing hormone/follicle-stimulating hormone in the combined therapy group were superior to those in the Chinese medicine and ear acupuncture groups (all P < 0.05). After treatment, recombinant human leptin and adiponectin in the combined therapy and Chinese medicine groups were superior to those measured before treatment (both P < 0.05). After treatment, only adiponectin was significantly increased in the early acupuncture group compared with before treatment ( P < 0.05). After treatment, tumor necrosis factor α and interleukin-6 in the combined therapy group were (4.12 ± 1.54) μg/L and (3.09 ± 1.41) ng/L respectively, which were significantly decreased compared with before treatment ( t = 21.66, 10.42, both P < 0.05). Conclusion:Tiaojing Xiaozhi Decoction combined with auricular acupoint embedding acupuncture can decrease body mass index, fat factor, and inflammatory factor levels, which can help decrease sex hormone levels and TCM syndrome integral, and has an obvious therapeutic effect on polycystic ovary syndrome.

ABSTRACT

Objective:To investigate the correlation between the level of anti Mullerian hormone (AMH) in serum and ovarian interstitial blood flow in patients with polycystic ovary syndrome (PCOS).Methods:The clinical data of 88 patients with PCOS (PCOS group) admitted to Jiangshan Hospital of Traditional Chinese Medicine from June 2019 to June 2022 and 50 women of the same age who underwent physical examination during the same period (normal control group) were collected retrospectively. The patients in the PCOS group were divided into two subgroups according to the homeostatic model assessment for insulin resistance index (HOMA-IR) evaluated by the steady-state model. Among them, patients with HOMA-IR ≥ 2.69 were divided into the insulin resistance subgroup (PCOS-IR subgroup, 50 cases), and patients with HOMA-IR<2.69 were divided into the non-insulin resistance subgroup (PCOS-NIR subgroup, 38 cases). The level of AMH were measured by electrochemiluminescence, and ovarian interstitial blood flow indicators, including peak blood flow velocity (PSV), pulsation index (PI), and resistance index (RI) were monitored. Pearson correlation test was used to analyze the correlation between serum AMH and insulin resistance and ovarian interstitial blood flow. Meanwhile, Logistic linear regression model was used to analyze the influencing factors of ovarian interstitial blood flow in patients with PCOS.Results:The levels of AMH, HOMA-IR and PSV in the PCOS group were higher than those in the normal control group: (2.13 ± 0.84) μg/L vs. (0.84 ± 0.29) μg/L, 4.6(2.0, 8.4) vs. 1.8(0.5, 3.9), (10.05 ± 1.52) cm/s vs.(6.78 ± 0.89) cm/s; the PI and RI in the PCOS group were lower than those in the control group: (1.14 ± 0.26)% vs. (2.01 ± 0.53)%, (0.37 ± 0.18)% vs. (0.85 ± 0.33)%, there were statistical differences ( P<0.05). The levels of AMH, HOMA-IR and PSV in the PCOS-IR subgroup were higher than those in the PCOS-NIR subgroup: (2.68 ± 0.81) μg/L vs. (1.59 ± 0.43) μg/L, (10.74 ± 2.32) cm/s vs. (7.93 ± 1.90) cm/s, 7.2(3.1, 15.8) vs. 2.1(0.6, 5.3); the PI and RI in the PCOS-IR subgroup were lower than those in the PCOS-NIR subgroup: (0.88 ± 0.35)% vs. (1.52 ± 0.50)%, (0.29 ± 0.04)% vs. (0.51 ± 0.05)%, there were statistical differences ( P<0.05). Pearson correlation analysis showed that the level of AMH were positively correlated with PSV and HOMA-IR ( r = 0.694 and 0.540, P<0.05), but negatively correlated with PI and RI( r = - 0.687 and - 0.692, P<0.05). Logistic linear regression model analysis showed that AMH and HOMA-IR were risk factors for ovarian interstitial blood flow in patients with PCOS( P<0.05). Conclusions:The serum AMH level in patients with PCOS is abnormally high and increases with insulin resistance. At the same time, the imbalance of AMH expression plays an important role in the increase of abnormal ovarian interstitial blood flow.

ABSTRACT

Objective:To discuss the correlation of serum 25-hydroxyvitamin D3[25(OH)D3] with chronic inflammation and insulin resistance (IR) in polycystic ovarian syndrome (PCOS) patients.Methods:One hundred and twenty-four PCOS patients registered from January 2018 to January 2020 in the Second Affiliated Hospital of Hebei North University were selected retrospectively. According to the difference of body mass index (BMI), the patients were divided into PCOS 1 group (BMI<25 kg/m 2, 64 cases) and PCOS 2 group (BMI≥25 kg/m 2, 60 cases). At the same time, 60 patients with simple obesity were selected as the obesity group and 58 healthy subjects were selected as the control group. The somatology indicators, gonadal hormone, serum 25(OH)D3, insulin resistance (IR) related index and chronic inflammation factors were measured, the correlations of serum 25(OH)D3 with relevant indicators were analyzed by Pearson correlation analysis. Results:The BMI, waist hip ratio, testosterone(T), luteinizing hormone (LH) / follicle-stimulating hormone (FSH), free androgen index(FAI), fasting insulin (FINS), fasting plasma glucose (FPG), insulin resistance index (HOMA-IR), insulin sensitivity index (ISI) in the four groups had significant differences ( P<0.05); the level of 25(OH)D3 in the PCOS 1 group was lower than that in the PCOS 2 group: (1.14 ± 0.36) nmol/L vs. (1.83 ± 0.25) nmol/L, P<0.05; the levels of FINS, HOMA-IR in the PCOS 2 group were higher than those in the PCOS 1 group, obesity group and control group: (13.26 ± 2.61) mg/L vs. (5.58 ± 1.03), (6.63 ± 1.42), (4.66 ± 0.85) mg/L, 1.49 ± 0.37 vs. 1.15 ± 0.20, 1.12 ± 0.22, 0.96 ± 0.11, P<0.05; the level of ISI in the PCOS 2 group was lower than that in the PCOS1 group, obesity group and control group: - 4.19 ± 0.78 vs. - 3.52 ± 0.74, - 3.23 ± 0.53, - 3.06 ± 0.54, P<0.05. The levels of interleukin-6(IL-6), transforming growth factor-β(TGF-β), tumor necrosis factor-α(TNF-α) in the four groups had significant differences ( P<0.05); the level of IL-6 in the PCOS 2 group was higher than that in the PCOS 1 group: (18.15 ± 4.93) ng/L vs. (14.77 ± 4.58) ng/L, P<0.05. The results of Pearson correlation analysis showed that the serum of 25(OH)D3 had negative correlation with IL-6, BMI, waist hip ratio, T, FINS, ISI, TGF-β and TNF-α( r = - 0.582, - 0.242, - 0.371, - 0.203, - 0.208, - 0.267, - 0.723, - 0.617, P<0.05). Conclusions:Serum 25(OH)D3 is correlated with chronic inflammation and IR, and involved into the genesis and progression of PCOS.

ABSTRACT

【Objective】 To investigate the role of LIF/LIFR/STAT3 pathway in endometrial receptivity in rats with polycystic ovary syndrome (PCOS). 【Methods】 Forty 21-day-old SD female rats were divided into normal (control) group, model group, sham-operation group, and LIF group with 10 rats in each. The rat model of PCOS was constructed by subcutaneous injection of prasterone sodium sulfate at the back of the neck. The serum levels of testosterone (T), glucose and insulin in each group were detected. The morphological changes of the uterus in each group were observed by HE staining, and the morphological changes of endometrium were measured. Immunohistochemistry, Western blotting, and Real-time fluorescence quantitative PCR(qRT-PCR) were used to determine the protein expression and mRNA expression of LIF and STAT3 in rat endometrium. 【Results】 Compared with control group, the levels of integrin avb3, serum T, insulin and glucose in PCOS rats were significantly increased (P=0.000, P=0.000, P=0.001). Supplementation of exogenous LIF could significantly reduce the levels of integrin avb3, serum T, glucose and insulin in PCOS rats (P=0.000, P=0.002, P=0.003, P=0.007). HE results showed that exogenous LIF could reduce uterine cavity and glandular morphology in PCOS rats and increase the equivalent diameter (P=0.000, P=0.000) and area (P=0.000, P=0.000) of uterine glands and glandular cavity, the ratio of glandular interstitial area (P=0.000), and the average endometrial thickness (P=0.006), with statistically significant differences. Immunohistochemistry, Western blotting, and qRT-PCR results showed that the expression levels of LIF and p-STAT3 protein and mRNA in model group were significantly decreased compared with control group. Compared with model group, the protein and mRNA expressions of LIF and p-STAT3 in LIF group were significantly increased (P<0.05). 【Conclusion】 Exogenous LIF supplementation can improve endometrial receptivity in PCOS rats, and its mechanism is related to the LIF/LIFR/STAT3 pathway.
