We analyzed data from the CDC Pregnancy Risk Assessment of Monitoring System, specifically Standard Core and Phase 8 responses, with 9549 respondents across the United States through SPSS 28 software in this cross-sectional study. Two variables assessed PCOS status in respondents: history of PCOS and PCOS during pregnancy. With a history of PCOS, there were significantly increased odds of diabetic (OR 1.665, p < 0.001), hypertensive disorders (OR 1.589, p < 0.001) during pregnancy, neonatal mortality (OR 1.550, p < 0.001), cesarean section (C/S) (OR 1.489, p < 0.001), and preterm prelabor rupture of membranes (PPROM) (OR 2.081, p < 0.001). With PCOS diagnosed during pregnancy, there were significantly greater odds of diabetes (OR 3.278, p < 0.001), hypertensive disorders (OR 2.935, p < 0.001) during pregnancy, and significantly decreased risk for small for gestational age (2 standard deviations) (OR 0.337, p = 0.024). PCOS is a significant risk factor that contributes to maternal morbidity. Our results support the hypothesis that PCOS’ impact extends well into a woman’s obstetrical journey, with varying degrees of associated adverse maternal and fetal risks. Preliminary pathophysiologic explanations associated with PCOS gestational diabetes include pre-existing insulin resistance. Meanwhile, altered placentation and endovascular changes associated with PCOS secondary to a baseline deranged metabolic environment predispose patients to developing hypertensive disorders, PPROM, and preterm delivery. Associations between neonatal mortality and C/S can be attributed to elevated maternal body mass index. The pathophysiologic link between PCOS and the above obstetrical outcomes still remains unknown, necessitating further investigation;however, this study identifies the outcomes that require the most attention at this time.展开更多

Our objective was to study the association between PCOS phenotypes and IVF/ICSI results in women admitted to Gynaecological Endoscopic Surgery and Human Reproductive Teaching Hospital (CHRACERH). Material and Method: We carried out a cohort study with historical-prospective data collection over a period of seven years (January 2016 to March 2023) at Chracerh. PCOS patients were subdivided into 4 subgroups A, B, C and D. Results: We recruited 128 patients including 64 PCOS patients divided into four phenotypes and 64 non-PCOS patients constituting the control group. Phenotype D without hyperandrogenism had used the lowest dose of gonadotropins, i.e. 1939.7 ± 454.3 IU, and had produced a greater quantity of estradiol on the day ovulation was triggered (6529.8 ± 4324.8 ng/ml). The average number of punctured follicles and mature oocytes were higher in the phenotype D group. Ovarian hyperstimulation syndrome (OHSS) occurred mainly in phenotype D (3/35), with an estimated prevalence of 2.3%. The fertilization rate seemed lower in the hyperandrogenic phenotypes A, B, C compared to the group without hyperandrogenism without significant difference (p = 0.461). The biological pregnancy rate and live birth rate were comparable between the different groups. Conclusion: Phenotype D used less dose of gonadotropins. Biological pregnancy and live birth rates were comparable between the different phenotypes.展开更多

Laparoscopic ovarian drilling (LOD) is a treatment for PCOS that allows the laparoscopic identification of other intra-abdominal lesions and the provision of diagnostic treatment. This study reports a case of PCOS with an ovarian mass in which LOD was aggressively used and a granulosa cell tumor (GCT) was found. A 34-year-old woman with secondary amenorrhea and irregular menstrual cycles presented to the emergency department with abdominal pain of unknown etiology. Imaging studies revealed a 6-cm left ovarian mass with an internal appearance suggestive of a hemorrhage. The patient’s secondary amenorrhea was subsequently diagnosed as PCOS, and LOD was performed to preserve her fertility. Simultaneously, a cystectomy was performed to evaluate the tumor in the left ovary;the diagnosis was adult-type GCT. Although concomitant GCT and PCOS are extremely rare, the two conditions have similar clinical manifestations. In women of reproductive age, the impact of surgery on future fertility should be considered, and the initial surgical technique should be chosen carefully.展开更多

Methods: A total of 80 PCOS patients who received treatment at the First Affiliated Hospital of Guangxi University of Chinese Medicine between October 2022 and March 2024 were enrolled in this study. They were randomly divided into a control group (n = 40) and an observation group (n = 40). The control group received conventional Western medical treatments, while the observation group was administered TCM combined with acupoint injection and herbal patch application. Pre- and post-treatment conditions were compared between the two groups. Results: After treatment, the overall effective rate was significantly higher in the observation group compared to the control group (P 0.05). Following treatment, both ovulation and pregnancy rates increased in both groups, but the increase was more evident in the observation group, showing a statistically significant difference (P < 0.01). Conclusion: For patients with oligoovulation or anovulation due to PCOS, the combined use of TCM, acupoint injection, and herbal patch application appears to be effective in improving systemic symptoms and achieving notable clinical outcomes.展开更多

[Methods] Ten of 40 female SD rats were randomly selected as the normal group, and the other 30 rats were treated with letrozole combined with high-fat diet to establish the PCOS rat model. After successful modeling, the model group was randomly divided into Qigongwan group, positive Daying-35 (Ethinylestradiol and Cyproterone Acetate Tablets) group and model group, with 10 rats in each group. Qigongwan group was given 14.7 g/(kg·d) by gavage, Daying-35 group was given 0.21 mg/(kg·d) by oral gavage, and normal group and model group were given the same amount of distilled water, and the intervention lasted for 21 d. ELISA method was used to detect the levels of hormones such as follicle-stimulating hormone (FSH), luteinizing hormone (LH), testosterone (T), estradiol (E 2) and progesterone (P) in serum. HE staining was used to observe the pathological morphological changes of ovarian tissues;TUNEL staining was used to observe apoptosis of ovarian tissue granule cells;the expression of Wnt, β-catenin protein in rat ovarian tissue was detected by immunohistochemistry. [Results] (i) Compared with the model group, Qigongwan group and Daying-35 group could significantly increase serum E 2 and P levels, significantly reduce serum T levels ( P <0.01), significantly reduce serum LH levels and LH/FSH ratio ( P <0.01), and increase serum FSH levels ( P <0.05) in different degrees. (ii)The results of HE staining showed that compared with the model group, Qigongwan and Daying-35 groups could improve follicular development and reduce atretic follicles in different degrees. Compared with Daying-35 group, the number of GC layers in Qigongwan group was significantly increased. (iii) The results of TUNEL staining showed that compared with the model group, the rate of TUNEL-positive cells in the Qigongwan group and Daying-35 group decreased significantly ( P <0.01). (iv) The immunohistochemical results showed that compared with the model group, the expression levels of wnt and β-catenin in the Qigongwan group and the Daying-35 group increased in different degrees ( P <0.05), and the expression range increased. [Conclusions] Qigongwan can regulate the secretion level of sex hormones such as FSH and LH, improve the pathological damage of ovarian tissue, and inhibit apoptosis of ovarian granule cells, and its mechanism may be related to the activation of Wnt/β-catenin signaling pathway.展开更多

文摘Objective To investigate the relationship and potential pathways between metal(loid)exposure and the risk of polycystic ovary syndrome(PCOS)in women of childbearing age.Methods This case-control study included 200 patients with PCOS(cases)and 896 non-PCOS controls with the age of 25-37 years.The concentrations of 29 metal(loid)s in the follicular fluid(FF)and clinical indicators in the serum were measured in all participants.Logistic regression analysis and mediation analysis were conducted to evaluate the associations between metal(loid)exposure and PCOS risk and investigate the possible roles of clinical indicators,respectively.Results Logistic regression analysis revealed an association between high copper levels in FF and increased PCOS risk(highest vs.lowest quartile:adjusted odds ratio=2.94,95%confidence interval:1.83-4.72).A high luteinizing hormone/follicle-stimulating hormone ratio and elevated levels of testosterone and anti-Müllerian hormone(AMH)were strongly associated with increased PCOS risk induced by high copper exposure.The mediation analysis indicated a mediating effect of AMH in the association between copper exposure and PCOS risk.Conclusion Copper may affect PCOS risk through the hypothalamic-pituitary-ovarian axis,mediated by AMH.Copper exposure and internal AMH levels are important indicators for early warning of PCOS development.
文摘To elucidate the potential mechanism of Wuji powder in treating polycystic ovary syndrome(PCOS),this study utilized TCMSP database to screen the active ingredients of each constituent drug in Wuji powder.Subsequently,we predicted the target proteins associated with these active ingredients.In parallel,we employed the GeneCards database to identify genes related to PCOS and determined the intersection of drug targets and disease targets using the online tool available at http://bioinformatics.psb.ugent.be/webtools/Venn/.The shared genes were considered as the target proteins of Wuji powder in the treatment of PCOS.Utilizing the String website,we constructed a protein-protein interaction(PPI)network diagram and identified key protein modules and hub genes within the PPI network using Cytoscape 3.7.1 software.Further analysis in the DAVID database involved GO and KEGG pathway enrichment analyses of the genes within the identified key modules.Our investigation revealed a total of 63 active ingredients in Wuji powder with potential therapeutic effects on PCOS,corresponding to 266 drug targets.Intersection with PCOS-related disease targets yielded 174 shared targets.Ten key modules and ten hub genes(TNF,MMP9,AKT1,ECG,VEGFA,PTGS2,IL-6,MAPK3,STAT3,and CXCL8)were identified through network analysis.KEGG pathway enrichment analysis uncovered 58 signaling pathways,including TNF,MAPK,and PI3K-Akt signaling pathways.GO functional annotation delineated five cellular components(CC),nine molecular functions(MF),and 58 biological processes(BP).Noteworthy findings included extracellular space,enzyme binding,and drug response among CC,MF,and BP categories,respectively.These results collectively suggested that Wuji powder might exert its therapeutic effects on PCOS by modulating the TNF/PI3K/AKT signaling pathway.
文摘BACKGROUND To retrospectively report the safety and efficacy of renal transcatheter arterial embolization for treating autosomal dominant polycystic kidney disease(ADPKD)patients with gross hematuria.CASE SUMMARY The purpose of this study is to retrospectively report the safety and efficacy of renal transcatheter arterial embolization for treating ADPKD patients with gross hematuria.Materials and methods:During the period from January 2018 to December 2019,renal transcatheter arterial embolization was carried out on 6 patients with polycystic kidneys and gross hematuria.Renal arteriography was performed first,and then we determined the location of the hemorrhage and performed embolization under digital subtraction angiography monitoring.Improvements in routine blood test results,routine urine test results,urine color and postoperative reactions were observed and analyzed.Results:Renal transcatheter arterial embolization was successfully conducted in 6 patients.The indices of 5 patients and the color of gross hematuria improved after surgery compared with before surgery.No severe complication reactions occurred.CONCLUSION For autosomal dominant polycystic kidney syndrome patients with gross hematuria,transcatheter arterial embolization was safe and effective.

文摘BACKGROUND Renal cell carcinoma(RCC)is more common in patients with autosomal dominant polycystic kidney disease(ADPKD)than in the general population.Diagnosing RCC in ADPKD is challenging due to the presence of multiple renal cysts,often leading to delays and difficulties in distinguishing RCC from cyst infection or hemorrhage.A total of 38 kidneys were excised from 19 patients,with a mean age of 56.8 years and an average hemodialysis duration of 84.2 months.Eight patients underwent open nephrectomies,and 11 underwent hand-assisted laparoscopic nephrec-tomies.RCC was detected in 15.8%of kidneys,affecting 21.1%of patients.Two patients had multifocal RCC in both kidneys.All RCC cases were pT1 stage,with the largest lesion averaging 16.5 mm in diameter.The average operative duration was 120 minutes,with intraoperative blood loss averaging 184.2 mL.Five patients required blood transfusions.Postoperative complications occurred in five patients,with a mean hospital stay of 17.1 days.The mean follow-up period was 28.1 months.CONCLUSION The prevalence of RCC is higher in patients with ADPKD with ESRD than in those with ESRD alone.Thus,clinicians should be cautious and implement surveillance programs to monitor the development of RCC in patients with ADPKD,particularly those on dialysis.
文摘BACKGROUND Polycystic kidney disease(PKD)is the most common genetic cause of kidney disease.It is a progressive and irreversible condition that can lead to end-stage renal disease and many other visceral complications.Current comprehensive data on PKD patterns in Africa is lacking.AIM To describe the prevalence and outcomes of PKD in the African population.METHODS A literature search of PubMed,African journal online,and Google Scholar databases between 2000 and 2023 was performed.The Preferred Reporting Items for Systematic Reviews and Meta-Analyses were followed to design the study.Clinical presentations and outcomes of patients were extracted from the included studies.RESULTS Out of 106 articles,we included 13 studies from 7 African countries.Ten of them were retrospective descriptive studies concerning 943 PKD patients with a mean age of 47.9 years.The accurate prevalence and incidence of PKD were not known but it represented the third causal nephropathy among dialysis patients.In majority of patients,the diagnosis of the disease was often delayed.Kidney function impairment,abdominal mass,and hypertension were the leading symptoms at presentation with a pooled prevalence of 72.1%(69.1-75.1),65.8%(62.2-69.4),and 57.4%(54.2-60.6)respectively.Hematuria and infections were the most frequent complications.Genotyping was performed in few studies that revealed a high proportion of new mutations mainly in the PKD1 gene.CONCLUSION The prevalence of PKD in African populations is not clearly defined.Clinical symptoms were almost present with most patients who had kidney function impairment and abdominal mass at the diagnostic.Larger studies including genetic testing are needed to determine the burden of PKD in African populations.
文摘Polycystic ovarian syndrome (PCOS) disrupts ovulation leading to both infertility and miscarriage;yet, its impact on obstetrical outcomes remains largely uncertain due to conflicting findings. We analyzed data from the CDC Pregnancy Risk Assessment of Monitoring System, specifically Standard Core and Phase 8 responses, with 9549 respondents across the United States through SPSS 28 software in this cross-sectional study. Two variables assessed PCOS status in respondents: history of PCOS and PCOS during pregnancy. With a history of PCOS, there were significantly increased odds of diabetic (OR 1.665, p < 0.001), hypertensive disorders (OR 1.589, p < 0.001) during pregnancy, neonatal mortality (OR 1.550, p < 0.001), cesarean section (C/S) (OR 1.489, p < 0.001), and preterm prelabor rupture of membranes (PPROM) (OR 2.081, p < 0.001). With PCOS diagnosed during pregnancy, there were significantly greater odds of diabetes (OR 3.278, p < 0.001), hypertensive disorders (OR 2.935, p < 0.001) during pregnancy, and significantly decreased risk for small for gestational age (2 standard deviations) (OR 0.337, p = 0.024). PCOS is a significant risk factor that contributes to maternal morbidity. Our results support the hypothesis that PCOS’ impact extends well into a woman’s obstetrical journey, with varying degrees of associated adverse maternal and fetal risks. Preliminary pathophysiologic explanations associated with PCOS gestational diabetes include pre-existing insulin resistance. Meanwhile, altered placentation and endovascular changes associated with PCOS secondary to a baseline deranged metabolic environment predispose patients to developing hypertensive disorders, PPROM, and preterm delivery. Associations between neonatal mortality and C/S can be attributed to elevated maternal body mass index. The pathophysiologic link between PCOS and the above obstetrical outcomes still remains unknown, necessitating further investigation;however, this study identifies the outcomes that require the most attention at this time.
文摘Background: In Vitro Fertilization/Intracytoplasmic Sperm Injection (IVF/ICSI) represents the final step in the management of Polycystic Ovarian Syndrome (PCOS). Our objective was to study the association between PCOS phenotypes and IVF/ICSI results in women admitted to Gynaecological Endoscopic Surgery and Human Reproductive Teaching Hospital (CHRACERH). Material and Method: We carried out a cohort study with historical-prospective data collection over a period of seven years (January 2016 to March 2023) at Chracerh. PCOS patients were subdivided into 4 subgroups A, B, C and D. Results: We recruited 128 patients including 64 PCOS patients divided into four phenotypes and 64 non-PCOS patients constituting the control group. Phenotype D without hyperandrogenism had used the lowest dose of gonadotropins, i.e. 1939.7 ± 454.3 IU, and had produced a greater quantity of estradiol on the day ovulation was triggered (6529.8 ± 4324.8 ng/ml). The average number of punctured follicles and mature oocytes were higher in the phenotype D group. Ovarian hyperstimulation syndrome (OHSS) occurred mainly in phenotype D (3/35), with an estimated prevalence of 2.3%. The fertilization rate seemed lower in the hyperandrogenic phenotypes A, B, C compared to the group without hyperandrogenism without significant difference (p = 0.461). The biological pregnancy rate and live birth rate were comparable between the different groups. Conclusion: Phenotype D used less dose of gonadotropins. Biological pregnancy and live birth rates were comparable between the different phenotypes.
文摘Polycystic ovary syndrome (PCOS) is a major cause of anovulatory infertility. Laparoscopic ovarian drilling (LOD) is a treatment for PCOS that allows the laparoscopic identification of other intra-abdominal lesions and the provision of diagnostic treatment. This study reports a case of PCOS with an ovarian mass in which LOD was aggressively used and a granulosa cell tumor (GCT) was found. A 34-year-old woman with secondary amenorrhea and irregular menstrual cycles presented to the emergency department with abdominal pain of unknown etiology. Imaging studies revealed a 6-cm left ovarian mass with an internal appearance suggestive of a hemorrhage. The patient’s secondary amenorrhea was subsequently diagnosed as PCOS, and LOD was performed to preserve her fertility. Simultaneously, a cystectomy was performed to evaluate the tumor in the left ovary;the diagnosis was adult-type GCT. Although concomitant GCT and PCOS are extremely rare, the two conditions have similar clinical manifestations. In women of reproductive age, the impact of surgery on future fertility should be considered, and the initial surgical technique should be chosen carefully.
文摘Objective: To observe the therapeutic effect of combined traditional Chinese medicine (TCM) therapy with acupoint injection and herbal patch application on patients with ovulatory dysfunction associated with polycystic ovary syndrome (PCOS). Methods: A total of 80 PCOS patients who received treatment at the First Affiliated Hospital of Guangxi University of Chinese Medicine between October 2022 and March 2024 were enrolled in this study. They were randomly divided into a control group (n = 40) and an observation group (n = 40). The control group received conventional Western medical treatments, while the observation group was administered TCM combined with acupoint injection and herbal patch application. Pre- and post-treatment conditions were compared between the two groups. Results: After treatment, the overall effective rate was significantly higher in the observation group compared to the control group (P 0.05). Following treatment, both ovulation and pregnancy rates increased in both groups, but the increase was more evident in the observation group, showing a statistically significant difference (P < 0.01). Conclusion: For patients with oligoovulation or anovulation due to PCOS, the combined use of TCM, acupoint injection, and herbal patch application appears to be effective in improving systemic symptoms and achieving notable clinical outcomes.

文摘Objective:To investigate the potential activity of novel herbal combination and novel herbal formulation(syrup)in female Sprague Dawley rats with letrozole-induced polycystic ovary syndrome(PCOS).Methods:Forty-two rats were randomly divided into seven groups with six rats in each group.Group 1 received 0.5%carboxy methylcellulose orally for 37 days and served as the normal control group.Group 2 was orally administered with letrozole of 1 mg/kg for 21 days and served as the PCOS induction group without treatment.Group 3 to 7 were administered with letrozole of 1 mg/kg for 21 days orally to induce PCOS,and then respectively received clomiphene citrate at 1 mg/kg,100 and 200 mg/kg of novel herbal combination,200 mg/kg of novel herbal formulation(syrup),and 400 mg/kg of marketed formulation of Pushyanuga churna,once daily for 15 days.Effects of the novel herbal combination and its syrup formulation were evaluated on the hormonal profile,the levels of antioxidants,the lipid profile and on the ovarian morphology,using letrozole-induced PCOS model in rats.Results:Letrozole caused alterations in hormonal levels and lipid levels similar to PCOS and ovarian histology showed presence of ovarian cysts confirming the induction of PCOS in rats.On treatment with the novel herbal combination and its syrup formulation in PCOS-induced rats,the altered hormonal and lipid profiles showed significant recovery to normal levels.Ovarian histology confirmed the restoration of folliculogenesis in the PCOS-induced rats.The treatment with the syrup formulation of novel herbal combination was found to be more effective than novel herbal combination and showed better recovery in various parameters evaluated.The results of the study,however,suggested that treatment with novel herbal combination and its syrup formulation provided minimal protection against oxidative stress caused due to the induction of PCOS.Conclusions:The integrated approach for management of PCOS is to counterbalance the limitations associated with modern therapy.Both the novel herbal combination and the syrup formulation of novel herbal combination show efficacy in the management of PCOS in rats and restore folliculogenesis in the ovary.The syrup formulation of novel herbal combination is most effective in the management of PCOS and shows potential to be developed as an adjuvant therapeutic agent.
文摘Objective:To investigate the protective effect of vitamin E in dehydroepiandrosterone(DHEA)-induced polycystic ovary in rats.Methods:Premature female Wistar rats were randomly allocated into four groups,with 7 rats in each group.Group栺received corn oil(vehicle)and served as the control group;group栻received 0.2 mL of 0.06 mg/g DHEA in corn oil;group栿received 200 mg/kg vitamin E;group桇received DHEA plus vitamin E.All treatments lasted for 15 days,with DHEA administered subcutaneously,while vitamin E and corn oil were administered orally.After the experiment,serum samples and ovaries were harvested for biochemical,immunohistochemical,hormonal,and histological analysis.The ovarian mRNA expression of androgen receptor was analyzed by reverse transcriptase quantitative polymerase chain reaction(qPCR).Results:The antioxidant and metabolic enzyme activity significantly decreased in the DHEA-treated rats compared to the control rats(P<0.05).Administration of vitamin E to DHEAtreated rats significantly decreased cytokines and malondialdehyde compared to the DHEA-treated rats.The histological analysis showed reduced atretic and cystic ovaries,increased E-cadherin and Bcl-2 expression,and reduced expression of Bax in the DHEAtreated rats co-treated with vitamin E.The mRNA expression of androgen receptor was upregulated in the DHEA-treated rats compared to the control rats.Conclusions:Vitamin E ameliorates the hyperandrogenic effect of DHEA-induced polycystic ovaries via metabolic,antioxidant,and anti-apoptotic pathways.

文摘BACKGROUND Insulin resistance(IR)was reported in most polycystic ovarian syndrome(PCOS)cases.Metformin,a biguanide drug,successfully reduced IR.Homeostatic Model Assessment for IR(HOMA-IR)and Doppler parameters assessed metformin's effectiveness.AIM To verify whether the area under the curve of the internal carotid artery(AUC-ICA)Doppler wave can be a useful marker for assessing IR among PCOS cases who presented with menstrual irregularity and were treated with metformin over 6 mo.METHODS An observational,cross-sectional study recruited 54 eligible PCOS women;the anthropometrics were as follows:age,body mass index(BMI),menstrual cycle days,biochemical serum cholesterol,low and high-density lipoprotein,sex hormone-binding globulin,fasting blood glucose,and HOMA-IR,hormonal testosterone,luteinizing hormone over follicle-stimulating hormone ratio,and ultrasonic pulsatility index(PI)and resistance index(RI),carotid artery intima-media thickness(CIMT)and(AUC-ICA)parameters were initially recorded and repeated 3 mo and 6 mo later with metformin tab 500 mg;three times/day for 6 mo.In addition,AUC-ICA was assessed by taking repeated systolic and diastolic wave height measurements.RESULTS Metformin caused a progressive reduction in BMI,menstrual cycle days,biochemical hormonal,and Doppler parameters(CIMT,PI,RI,and AUC-ICA).AUC-ICA correlated strongly to all PCOS parameters.AUC-ICA correlated inversely with treatment time(r=-0.98,P<0.001)and positively with HOMA-IR(r=0.98,P<0.0001).Via the best subset regression model,the AUC-ICA had the highest predictive value for HOMA-IR.CONCLUSION AUC-ICA preceded PI,RI,and CIMT with a strong,meaningful correlation to all PCOS parameters,making it a reliable marker for the assessment of IR,especially during metformin therapy.Further studies are recommended to promote the application in practice.

文摘BACKGROUND Polycystic ovary syndrome(PCOS)is closely related to obesity,and weight loss can significantly improve the metabolic,endocrine and reproductive functions of obese individuals with PCOS.However,the efficacy of laparoscopic sleeve gastrectomy(LSG)for obesity with PCOS are unclear.AIM The purpose of the study was to investigate the effect of LSG on related variables in obese patients with PCOS.METHODS A retrospective analysis was performed on 32 obese patients with PCOS who received LSG treatment at the Third Hospital of Shanxi Medical University from 2013 to 2020.The changes in anthropometric indices,insulin,testosterone,estradiol,follicle stimulating hormone(FSH),luteinizing hormone(LH),menstrual cycle and LH/FSH ratio before and 1 mo,3 mo,6 mo and 12 mo after the operation were statistically analyzed.RESULTS At 1 mo,3 mo,6 mo and 12 mo after surgery,the anthropometric indices,such as body weight and body mass index,of all patients were lower than those before the operation.The percentage excess weight loss(EWL%)at 1 mo,3 mo,6 mo and 1 year of follow-up were 25,40,46 and 65,respectively.The PCOS-related indices,such as insulin,testosterone,estradiol,follicle stimulating hormone(FSH),luteinizing hormone(LH)and menstrual cycle,were improved to varying degrees.During the 1-year follow-up,the average serum testosterone decreased from preoperative 0.72 ng/mL to 0.43 ng/mL(P<0.05),average fasting insulin level(9.0 mIU/mL,preoperative 34.2 mil,LH level,4.4 mIU/mL,preoperative 6.1 mIU/mL).The level of FSH(3.8 U/L,4.8 U/p0.05)and the ratio of LH/FSH(0.7,1.3/p0.05)were more relieved than those before surgery.During the postoperative follow-up,it was found that the menstrual cycle of 27 patients(nasty 27)returned to normal,and 6 patients(18%)who intended to become pregnant became pregnant within 1 year after surgery.CONCLUSION The weight loss effect of LSG is obvious and affirmative,and the endocrine index of obese patients with PCOS is also improved to some extent,although the mechanism is not clear.Laparoscopic sleeve gastrectomy is expected to become a backup choice for patients with polycystic ovaries in the future.

文摘BACKGROUND Many epidemiologic investigations have explored the relationship between viatmins and polycystic ovary syndrome(PCOS).However,the effectiveness of vitamin,vitamin-like nutrient,or mineral supplementation in reducing the risk of PCOS remains a subject of debate.AIM To investigate the impact of plasma levels of vitamins A,B12,D,E,and K on PCOS and key pathways implicated in its development,namely,insulin resistance,hyperlipidemia,and obesity,through Mendelian randomization(MR)analysis.METHODS Single nucleotide polymorphisms associated with vitamin levels were selected from genome-wide association studies.The primary analysis was performed using the random-effects inverse-variance-weighted approach.Complementary analyses were conducted using the weighted median,MR-Egger,MR-robust adjusted profile score,and MR-PRESSO approaches.RESULTS The results provided suggestive evidence of a decreased risk of PCOS with genetically predicted higher levels of vitamin E(odds ratio[OR]=0.118;95%confidence interval[CI]:0.071–0.226;P<0.001)and vitamin B12(OR=0.753,95%CI:0.568–0.998,P=0.048).An association was observed between vitamin E levels and insulin resistance(OR=0.977,95%CI:0.976–0.978,P<0.001).Additionally,genetically predicted higher concentrations of vitamins E,D,and A were suggested to be associated with a decreased risk of hyperlipidemia.Increased vitamins K and B12 levels were linked to a lower obesity risk(OR=0.917,95%CI:0.848–0.992,P=0.031).CONCLUSION The findings of this MR study suggest a causal relationship between increased vitamins A,D,E,K,and B12 levels and a reduced risk of PCOS or primary pathways implicated in its development.

文摘[Objectives] To explore the therapeutic effect and mechanism of Qigongwan on PCOS model rats by detecting the changes in sex hormone levels in rats with polycystic ovary syndrome (PCOS), and observing the effects of ovarian pathological morphological changes, apoptosis and expression of Wnt/β-β catenin signaling pathway protein. [Methods] Ten of 40 female SD rats were randomly selected as the normal group, and the other 30 rats were treated with letrozole combined with high-fat diet to establish the PCOS rat model. After successful modeling, the model group was randomly divided into Qigongwan group, positive Daying-35 (Ethinylestradiol and Cyproterone Acetate Tablets) group and model group, with 10 rats in each group. Qigongwan group was given 14.7 g/(kg·d) by gavage, Daying-35 group was given 0.21 mg/(kg·d) by oral gavage, and normal group and model group were given the same amount of distilled water, and the intervention lasted for 21 d. ELISA method was used to detect the levels of hormones such as follicle-stimulating hormone (FSH), luteinizing hormone (LH), testosterone (T), estradiol (E 2) and progesterone (P) in serum. HE staining was used to observe the pathological morphological changes of ovarian tissues;TUNEL staining was used to observe apoptosis of ovarian tissue granule cells;the expression of Wnt, β-catenin protein in rat ovarian tissue was detected by immunohistochemistry. [Results] (i) Compared with the model group, Qigongwan group and Daying-35 group could significantly increase serum E 2 and P levels, significantly reduce serum T levels ( P <0.01), significantly reduce serum LH levels and LH/FSH ratio ( P <0.01), and increase serum FSH levels ( P <0.05) in different degrees. (ii)The results of HE staining showed that compared with the model group, Qigongwan and Daying-35 groups could improve follicular development and reduce atretic follicles in different degrees. Compared with Daying-35 group, the number of GC layers in Qigongwan group was significantly increased. (iii) The results of TUNEL staining showed that compared with the model group, the rate of TUNEL-positive cells in the Qigongwan group and Daying-35 group decreased significantly ( P <0.01). (iv) The immunohistochemical results showed that compared with the model group, the expression levels of wnt and β-catenin in the Qigongwan group and the Daying-35 group increased in different degrees ( P <0.05), and the expression range increased. [Conclusions] Qigongwan can regulate the secretion level of sex hormones such as FSH and LH, improve the pathological damage of ovarian tissue, and inhibit apoptosis of ovarian granule cells, and its mechanism may be related to the activation of Wnt/β-catenin signaling pathway.
