拮抗剂方案中HCG扳机日直径16~18 mm卵泡比例对PCOS患者IVF-ET结局的影响

目的探讨拮抗剂方案中人绒毛膜促性腺激素(HCG)扳机日直径16~18 mm卵泡比例对接受拮抗剂方案的多囊卵巢综合征(PCOS)患者体外受精-胚胎移植(IVF-ET)结局的影响。方法回顾性分析2016年1月至2021年12月于南京医科大学附属妇产医院行IVF-ET助孕的PCOS患者的临床资料。根据HCG扳机日双侧卵巢直径16~18 mm卵泡比例以三分位法将患者分为三组,该比例<0.43为A组(262例),0.43~0.56为B组(267例),≥0.56为C组(247例)。比较三组一般临床资料、超促排卵周期情况、胚胎发育情况、体外受精周期后首次冻融胚胎移植(FET)情况以及妊娠、围产期结局。结果B组基础促黄体生成素(LH)、基础LH与基础促卵泡激素(FSH)比值显著高于A组和C组,差异有统计学意义(P<0.05)。A组促性腺激素(Gn)使用总量高于B组和C组,HCG扳机日雌二醇(E_(2))水平低于B组、C组,差异有统计学意义(P<0.05)。B组和C组获卵数、2原核(PN)数、卵裂数、囊胚形成数以及可移植胚胎数高于A组,差异有统计学意义(P<0.05)。C组囊胚形成率高于A组和B组,高评分囊胚率高于B组,差异有统计学意义(P<0.05)。三组移植胚胎数、移植胚胎天数、内膜准备方案及内膜厚度比较差异无统计学意义(P>0.05)。三组胚胎着床率、生化妊娠率、临床妊娠率、流产率、活产率、妊娠期糖尿病发生率及妊娠期高血压发生率等比较差异无统计学意义(P>0.05)。结论在拮抗剂方案中,HCG扳机日直径16~18 mm卵泡比例可反映卵母细胞发育潜能,当该比例≥0.56时可获得较好的获卵数、2PN数、卵裂数、囊胚形成数以及可移植胚胎数,在一定程度上可作为PCOS患者HCG扳机时机的参考指标,但该比例并不影响后续首次FET的妊娠结局。

Effects of Qigongwan on Wnt/β-catenin Signaling Pathway in Rats with Polycystic Ovary syndrome

[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.

Synchrony between Ovarian Function &Sleep in Polycystic Ovary Syndrome Patients

Polycystic ovary syndrome (PCOS) is a complex, multifaceted, heterogeneous disorder, affecting 4% to 18% of reproductive-aged women and is associated with reproductive, metabolic and psychological dysfunction. In this study we determined the relationship between the time to sleep and serum levels of neurohormones in polycystic ovary syndrome (PCOS). Totally 77 PCO patients(case group) and 97 non-PCOS infertile women (control subjects) participated in this study between February 2012 and February 2013. A PSQI sleep questionnaire was completed by each patient in both groups. PSQI sleep questionnaire score and serum concentration of adrenaline, noradrenaline, melatonin, β-endorphin, cortisol and progesterone were compared in two groups. The results of the study indicate that serum levels of melatonin and β-endorphin were lower in women with PCOS. Serum level of stress hormones, adrenaline and noradrenaline were significantly correlated with patients’ sleep time in study group. Serum level of adrenaline in control group was significantly lower in women who wake up earlier in the morning. All hormones except for cortisol had no significant correlation with PSQI global score in both groups and also the people who sleep less than 8 hours had lower cortisol level. These data showed that changes in cortisol in PCO women were due to damage of disturbed sleep at night. Our preliminary work provided this study with new insight into the interactions between sleep-wake cycles in PCO women with specific sleep patterns.

艾炳蔚教授基于“血不利则为水”治疗肥胖型PCOS的经验

“血不利则为水”是张仲景关于津血病理关系的重要理论。现代医家认为,肥胖型多囊卵巢综合征(PCOS)病机属本虚标实,以肾虚为本、痰瘀互结为标。痰瘀等有形实邪阻滞冲任胞宫,血行不畅,进而导致气、血、水相互为病,缠绵难愈,故活血利水是治疗肥胖型PCOS的根本大法,即血水同治、标本兼顾。基于此,艾师从临床与古籍出发,探索“血不利则为水”对针灸治疗肥胖型PCOS的临床指导意义,并从中获益匪浅。

A Network Pharmacology Analysis of Cang Fu Dao Tan Formula for the Treatment of Obese Polycystic Ovary Syndrome

Objective To explore the potential molecular targets of Cang Fu Dao Tan Formula(CFDTF)in the treatment of obese polycystic ovary syndrome(PCOS)using network pharmacology and bioinformatic approaches.Methods The potential blood-entry active compounds and targets of CFDTF were retrieved from the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP),and obese PCOS related gene targets were retrieved from GeneCard databases.A protein-protein interaction(PPI)network of CFDTF component-targets and obese PCOS diseasetargets was constructed using STRING.Gene Ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)pathway analysis of the intersection network were conducted using a Bioconductor database.Results In total,114 active compounds were screened according to oral bioavailability(OB)and drug similarity(DL),and 328 targets related to these constituents were obtained.Further,2559 target genes directly related to obese PCOS were obtained from the GeneCard databases,and 82 genes were obtained from the intersection of the component-target and disease-target PPI network.These genes were mainly involved in response to steroid hormones,nutrient levels and lipopolysaccharide as well as in other biological processes.Their molecular functions were mainly related to nuclear receptor activity,phosphatase binding and cytokine activity,and they were enriched in the cytoplasm,cell membrane and membrane region.Conclusions CFDTF consists of 114 active compounds that are responsible for its pharmacodynamic effects.It mainly regulates the AGE-RAGE signaling pathway in diabetic complications,bladder cancer,and hepatitis B and in other signaling networks.These findings provide certain theoretical and scientific basis for the treatment of obese PCOS with Chinese medicine.

Thyroid Disorders in Women with Polycystic Ovary Syndrome

Background: Polycystic ovary syndrome (PCOS) is one of the common endocrinopathies of women in the reproductive age group. Thyroid hormones have various effects on the reproductive system of female. PCOS and thyroid dysfunction are linked to each other since several years. Objective: To evaluate and detect the thyroid dysfunction in patients with PCOS attending in a tertiary care hospital in Bangladesh. Methodology: This was a prospective cross sectional study conducted from November 2018 to October 2019 at Department of Obstetrics and Gynecology in Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh on one hundred and fifty (150) PCOS women of reproductive age (15 - 45 years). All data of the study subjects regarding socio-demographic, anthropometric and clinical manifestations were recorded accordingly. Their thyroid function tests (serum level of FT3, FT4, TSH) were done at the hospital laboratory and results were recorded. Result: Mean (±SD) age of the study subjects was 24.57 ± 4.27 years. The maximum numbers [108 (72.0%)] of PCOS women were between 18 - 25 years age group. Among total (150) study population, 51 (34.0%) were overweight, 36 (24.0%) were obese and 63 (42.0%) were within normal weight level. Hirsutism was found in 87 (58%) study subjects while 24 (16%) subjects had acne in their face, 54 (36%) subjects had oligomenorrhea and 45 (30%) subjects had irregular periods. Among 150 PCOS women, 120 (80%) were married and 30 (20%) were single;of them primary infertility was detected in 58 (48.33%) women followed by the normal fertility status [51 (42.5%)] and 11 (9.17%) had secondary infertility. Among total (150) study subjects, 105 (70%) were in euthyroid state, hypothyroidism was found in 33 (22.0%) subjects and hyperthyroidism was detected in 12 (8%) subjects. Conclusions: Present study demonstrated that, thyroid disorders are prevalent in 30.0% of PCOS patients. Hypothyroidism is almost three-fold more prevalent than hyperthyroidism.

Hyponeurotrophinemia in Serum of Women with Polycystic Ovary Syndrome as a Low Grade Chronic Inflammation

Introduction: This study aimed to discuss about neuroimmune-pathophysiology of polycystic ovary syndrome (PCOS). Nerve growth factor (NGF) as modulator of neuro-endocrine-immune (NEI) system plays a critical role in tissue survival and homeostasis maintenance. It is a strong marker for sympathetic nerve activity. Women with PCO have enhanced ovarian NGF production. Over the past few decades, PCOS has been discussed as a low grade chronic inflammatory disease. In this study, we investigated the neuromodulator role of serum NGF and inflammatory cytokines (IL-1α, β, 17A and TNF-α) in women with PCOS. Material and Methods: 171 patients were investigated in two groups: study (n = 85 PCO) and control (n = 86). Serum levels of NGF-α and interleukins IL-1α, IL-1β, IL-17A and TNFα were determined in both groups by ELISA kit. Results: Data of this study showed that the level of NGF-α and IL-17A in serum of PCO women were lower than control group (p α, IL-1β were higher than control group in PCO women (p < 0.001). Conclusion: Probably inflammatory background in PCOS is the main cause of increased serum levels of IL-1α, IL-1β. Reduction of IL-17A and NGF in serum of PCO patients might be under the direct influence of the hyperactivity of sympathetic nervous system (SNS).

Polycystic Ovarian Syndrome and Female Infertility

Polycystic ovarian syndrome (PCOS) is the most common endocrine disorder in women of reproductive age, associated with chronic anovulation and hyperandrogenism. The cause of PCOS is multi-factorial and the mechanism is still unclear. A number of complications are closely related with PCOS such as infertility, hairy and obesity. Approximately up to one-third of females with PCOs have issues with infertility. Obesity is an independent factor which exacerbates infertility in PCOS, reduces the efficacy of infertility treatment and provokes a greater risk of miscarriage. Preconception counseling and guidelines play an initial major role in infertility treatment. The option of the most appropriate treatment depends upon various factors such as age, tubal patency, quality of sperm, experience, and duration of previous treatments and the level of anxiety of the couple. Tubal patency test and semen analysis are mandatory to decide the suitable treatment. Treatment modalities have two measures—non-pharmacological and the pharmacological. Oral clomiphene citrate remains the first line treatment to trigger ovulation. Gonadotrophin and laparoscopic ovarian drilling (LOD) surgery are the other treatment option. In vitro fertilization (IVF) and embryo transfer are the third line treatment and IVF remains the first option in the patient with diagnosed and established bilateral tubal occlusion and/or concentration of recovered motile sperm less than or equal to 5 million. Here, etiology, pathophysiology and molecular mechanisms of PCOS are reviewed, and perspectives are given for further research. The recent development, treatment, and diagnosis of PCOS are also highlighted. The summary will be of guiding significance in the prevention and treatment of PCOS.

经阴道超声检测参数对PCOS不孕症患者子宫内膜容受性的评估研究

目的探讨经阴道超声检测参数对多囊卵巢综合征(PCOS)不孕症患者子宫内膜容受性的评估价值。方法选取2016年10月至2018年9月重庆三峡中心医院收治的162例PCOS不孕症患者作为研究对象。均行子宫内膜胞饮突检查及阴道超声检测,观察子宫内膜胞饮突情况、子宫内膜厚度、容积与子宫螺旋动脉搏动指数(PI)、阻力指数(RI)、S/D(收缩期峰值血流速度/舒张末期血流速度)。根据子宫内膜胞饮突将162例患者分为容受性良好组与不良组,对比两组患者阴道超声检测参数,且采用Logistic回归分析法分析其对子宫内膜容受性的影响。结果162例患者经阴道超声检查,其中子宫内膜厚度(6.42±0.71)mm,子宫内膜容积(1.56±0.38)mL,PI(1.78±0.29),RI(0.79±0.03),S/D(3.84±0.41);子宫内膜容受性良好组患者子宫内膜厚度、子宫内膜容积均大于不良组患者,良好组患者PI、RI、S/D均小于不良组患者,差异均具有统计学意义(均P<0.05);良好组患者子宫内膜厚度≤7.0mm、子宫内膜容积≤2mL、PI≥1.6、RI≥0.72、S/D≥3.6、高雄激素血症、高胰岛素血症构成比占比均明显低于不良组患者,差异均具有统计学意义(均P<0.05),且经Logistic回归分析发现,其均是影响PCOS不孕症患者子宫内膜容受性的危险因素,差异均具有统计学意义(OR=5.223、4.080、2.591、2.998、3.522、2.930、3.684,均P<0.05)。结论经阴道超声检查可观察PCOS不孕症患者子宫内膜及子宫螺旋动脉血流动力学变化情况,且当检测参数显示为子宫内膜厚度≤7.0mm、子宫内膜容积≤2mL、PI≥1.6、RI≥0.72、S/D≥3.6时,此类患者子宫内膜容受性不良的风险增加,可指导临床工作。

CYP19基因多态性与PCOS发病相关性

目的研究芳香化酶基因(C YP19)第4内含子△3(TTTA)n微卫星多态性与多囊卵巢综合征(PCOS)发病、PCOS患者体重指数(BMI)和血清生殖激素之间的关系。方法收集PCOS和非PCOS人群的血液标本。记录临床数据并检测血清中的生殖激素。采用Chelex-100提取法从180例PCOS患者和127名非PCOS对照者的外周血标本中提取DNA。特异引物聚合酶链反应,产物经6%变性聚丙烯酰胺凝胶电泳分离,银染检测。结果正常对照和PCOS患者之间的△3(TTTA)n频率分布差异无统计学意义。二者均没有(TTTA)9。PCOS患者中各基因型个体之间的BMI和血清生殖激素差异无统计学意义。结论C YP19基因第4内含子的多态性与PCOS发病之间没有直接相关性,PCOS的雄激素升高不是其代谢下降,而是合成过多;同时C YP19基因第4内含子的多态性对PCOS患者的BMI和生殖激素也无影响。
