Objective

To assess the effects of the active metabolite of Bupropion, hydroxybupropion, on human spermatozoa in vitro.

Design

Laboratory based in vitro study.

Patients

Human sperm samples were collected from 45 normozoospermic patients (smokers and nonsmokers).

Exposure

Sperm samples were incubated at 37°C with 5% CO2 for 2 hours with and without the IC50 concentration of hydroxybupropion (1.9 μM).

Main Outcome Measures

Several sperm analysis were performed, including vitality, motility, chromatin condensation, DNA fragmentation, oxidative stress, mitochondria membrane potential, and acrosome integrity. High-speed video microscopy and Computer-Assisted Sperm Analysis provided a detailed evaluation of sperm motility.

Results

Hydroxybupropion exposure resulted in significant impairments in sperm vitality and motility, particularly in progressive motility. Chromatin condensation was significantly reduced, whereas DNA fragmentation, especially in the equatorial region, significantly increased. Mitochondria membrane potential, acrosomal integrity, and reactive oxygen species production also significantly decreased after exposure.

Conclusion

The findings indicate potential harm to sperm parameters, which may contribute to infertility. Understanding how Bupropion affects reproductive function is crucial for clinicians and patients to make informed decisions regarding the use of this medication.
目的:评价安非他酮(BUP)活性代谢物羟基安非他酮(OH-BUP)对体外人精子的影响。设计:基于实验室的体外研究。对象:从45例无精子患者(吸烟者和非吸烟者)中采集人类精子样本。暴露:精子样品在37°C, 5% CO2条件下,有或没有OH-BUP (1.9 μM) IC50浓度孵育2小时。主要观察指标:进行多项精子分析,包括活力、运动性、染色质凝聚、DNA断裂、氧化应激、线粒体膜电位和顶体完整性。高速视频显微镜和计算机辅助精子分析提供了精子活力的详细评估。结果:OH-BUP暴露导致精子活力和运动性明显受损,特别是在进行性运动性方面。染色质凝结明显减少,而DNA断裂明显增加,特别是在赤道地区。暴露后,线粒体膜电位、顶体完整性和活性氧的产生也显著降低。结论:研究结果提示对精子参数的潜在危害,可能导致不育。了解BUP如何影响生殖功能对于临床医生和患者在使用这种药物时做出明智的决定至关重要。

Objective

To study the potential association between pure male factor infertility (MFI) and the likelihood of a positive family history of cancer because limited information exists on the oncologic risk among relatives of men experiencing infertility.

Design

This cross-sectional, retrospective analysis considered the latest 1,168 men seeking medical help for primary couple's infertility at a single center. Infertility was defined according to the World Health Organization criteria.

Subjects

A total of 1,168 men seeking medical help for primary couple's infertility at a single center.

Intervention(s)

Patients underwent thorough assessments, including medical history, measured body mass index, laboratory investigations including semen analyses and sperm DNA fragmentation (SDF) index testing.

Main Outcome measure(s)

Abnormal SDF was defined as >30%. Descriptive statistics and logistic regression analyses tested the association between semen parameters, SDF, and positive cancer family history.

Result(s)

Of 1,168, 168 (14.4%) patients reported a positive cancer familial history. Patients with positive cancer family history were older (median interquartile range [IQR]: 37.00 [33.00–41.00] vs. 38.00 [34.00–41.00] years) and more frequently smokers (271 [27.1] vs. 64 [38.1]). Positive family history for malignancies was observed in 79 (40.9%), 66 (34.2%), 36 (18.7%), and 6 (3.1%) patients with a 1st, 2nd, 3rd, and 4th degree of kinship, respectively. At multivariable logistic regression analysis, SDF was positively associated with an increased risk of positive cancer family history in any (HR, 1.12; 95% CI, 1.04–2.1) and in 1st-degree relatives (HR, 1.01; 95% CI, 1.00–1.03). Similarly, abnormal SDF was associated with an increased risk of positive cancer family history in any relative (HR, 1.78; 95% CI, 1.12–2.87) and in 1st-degree relatives (HR, 1.92; 95% CI, 1.01–3.84).

Conclusion

Almost 14% of patients with MFI reported a familial history of cancer. Greater SDF levels emerged to be associated with a higher likelihood of a positive family history of cancer.
摘要目的:研究纯男性因素不育(MFI)与癌症家族史阳性可能性之间的潜在关联,因为关于男性不育亲属的肿瘤风险的信息有限。设计:这是一项横断面、回顾性分析,考虑了最近1168名在同一中心为第一对夫妇的不孕症寻求医疗帮助的男性。根据世卫组织标准定义不孕症。研究对象:1168名在同一中心为第一对夫妇不孕症寻求医疗帮助的男性。暴露:对患者进行全面评估,包括病史、测量的身体质量指数(BMI)、包括精液分析和精子DNA片段化(SDF)指数测试在内的实验室调查。主要观察指标:> ~ 30%为SDF异常。描述性统计和逻辑回归分析检验了精液参数、SDF和阳性癌症家族史之间的关系。结果:1168例患者中,168例(14.4%)报告了阳性癌症家族史。癌症家族史阳性的患者年龄较大[中位数(IQR): 37.00(33.00, 41.00)比38.00(34.00,41.00)岁;P =0.036)]和更频繁的吸烟者[271(27.1)比64 (38.1);分别为一级、二级、三级和四级亲缘关系。在多变量logistic回归分析中,SDF与任何癌症家族史阳性风险增加呈正相关(HR:1.12;95% ci:1.04 - 2.1;p=0.048)和一级亲属(HR:1.01;95% ci:1.00 - 1.03;p = 0.050)。同样,异常的SDF与任何亲属癌症家族史阳性的风险增加相关(HR:1.78;95% ci:1.12- 2.87;p=0.043)和一级亲属(HR:1.92;95% ci:1.01- 3.84;p = 0.049)。结论:近14%的MFI患者报告有癌症家族史。较高的SDF水平与较高的癌症家族史呈正相关。

目的:介绍一种用于卵母细胞胞浆内单精子注射(ICSI)的卵泡卵母细胞复合物(COCs)剥脱过程的创新非接触方法。设计:我们设计并制作了一种新型的声水动力镊子(AHT)来进行非接触剥蚀,并在小鼠模型上进行了测试。评估积云去除效率,植入前发育和活产,并与传统的手动移液剥落进行比较。实验对象:雌性B6D2F1/J小鼠14只(~ 4周龄),雄性B6D2F1/J小鼠9只(6 ~ 12周龄),CD-1雌性小鼠28只(~ 6周龄)进行实验干预和方法:基于聚焦声波原理设计了一种非接触式卵母细胞剥离平台。我们首先通过热像仪测量表面位移和温度来研究声强和热变异性,以确保安全操作。用40 IU/ml透明质酸酶作为对照的常规手动移液(MP)或用减少透明质酸酶量(15 IU/ml)的AHTs剥离COCs。实验组和对照组均行压痕icsi。进行了三次脱毛和人工授精实验。所有胚胎均在延时培养箱中监测。采用卡方检验比较胚胎发育率。胚胎形态动力学时间作为一个连续变量,采用单因素方差分析进行比较。对一些囊胚进行了胚胎移植。主要观察指标:测量并比较各种剥除方法的手术时间。比较对照组和试验组的受精、胚胎发育和形态动力学、妊娠率和活产率。结果:非接触性脱皮容易,无卵母细胞损伤。声波诱导的流体剪切是COC剥蚀的主要原因。当使用较低浓度的透明质酸酶时,每个卵母细胞的平均剥落时间减少了46%(对照组每个卵母细胞15秒,而AHT组每个卵母细胞8秒)。经MP和AHTs处理的卵母细胞的Piezo-ICSI存活率(86.1% vs 85.3%, P=0.80)、受精率(96.7% vs 94.1%, P=0.09)和囊胚率(88.0% vs 81.3%, P=0.06)相当。实验组和对照组的胚胎形态动力学具有可比性,表明声波对胚胎发育没有影响。MP组和AHT组的最终分娩率也具有可比性(51.3% vs 55.4%)。结论:声水动力镊子(AHTs)用于ICSI前COCs积云细胞的非接触清除,快速、安全、可靠。胚胎发育结果证实了它们的安全性,并验证了它们作为综合icsi芯片设备的潜力。

This study investigated whether luteinizing hormone receptor (LHR) expression varies in the granulosa cells of individual follicles according to the maturation stage of the oocytes harvested for assisted reproductive technology treatment. We observed minimal to no LHR messenger ribonucleic acid and protein expression in cumulus cells surrounding oocytes arrested in the germinal vesicle stage. Interestingly, their ability to mature was confirmed by rescue in vitro maturation, suggesting somatic cell LHR deficiency as a key factor for the retrieval of germinal vesicle oocytes in assisted reproductive technology procedures.
本研究探讨了促黄体生成素受体(LHR)在单个卵泡颗粒细胞中的表达是否随辅助生殖技术(ART)治疗卵母细胞成熟阶段的不同而变化。我们观察到在生发囊泡(GV)期卵母细胞周围的积云细胞中很少甚至没有LHR mRNA和蛋白的表达。有趣的是,它们的成熟能力被体外抢救成熟证实,这表明体细胞LHR缺陷是抗逆转录病毒治疗中恢复GV卵母细胞的关键因素。

Results

Transforming growth factor-beta 3 production decreased at 24 hours with relugolix 10 nM (0.80 ± 0.09-fold) and 100 nM (0.86 ± 0.06-fold) and at 48 hours with relugolix 1 nM (0.86 ± 0.05-fold) and 100 nM (0.86 ± 0.06-fold). pSMAD2/3 production decreased at 24 hours with relugolix 1 nM (0.71 ± 0.01-fold), 10 nM (0.68 ± 0.01-fold), and 100 nM (0.41 ± 0.10-fold). Compared with relugolix treatment alone at the same concentration, combination treatment at 24 hours resulted in significantly increased COL1A1, FN1, and VCAN production with relugolix 1 nM, 10 nM, and 100 nM. At 48 hours, combination treatment resulted in significantly increased COL1A1, FN1, and VCAN production with relugolix 10 nM and 100 nM.

Conclusion

Relugolix regulated leiomyoma size by decreasing COL1A1, FN1, and VCAN production. This effect is at least partly through the TGF-β pathway.
目的:确定口服GnRH拮抗剂relugolix是否通过TGF β途径影响平滑肌瘤细胞外基质的生成。主要观察指标:治疗和未治疗的平滑肌瘤细胞中TGF β、pSMAD2/3、SMAD2/3、COL1A1、FN1和VCAN的产生结果:在10nM(0.80 + 0.09倍,p0.04)和100nM(0.86 + 0.06倍,p0.03)和1nM(0.86 + 0.05倍,p0.01)和100nM(0.86 + 0.06倍,p0.04)时,relugolix治疗24小时TGF β3的产生减少。relugolix 1nM(0.71 + 0.01倍,p0.002)、10nM(0.68 + 0.01倍,p0.001)和100nM(0.41 + 0.10倍,p0.004)治疗24h后pSMAD2/3降低。与相同浓度的relugolix单独处理相比,在24小时联合处理时,relugolix 1nM、10nM和100nM的COL1A1、FN1和VCAN产量显著增加。在48小时时,10nM和100nM的relugolix联合处理显著增加COL1A1、FN1和VCAN的产生。结论:Relugolix通过降低COL1A1、FN1和VCAN的生成来调节平滑肌瘤的大小。这种作用至少部分是通过TGF β途径实现的。

Objective

To investigate the association between polycystic ovary syndrome (PCOS) and the rate of embryo development, using time-lapse monitoring systems, compared with a control group of women with mechanical (tubal) factor infertility.

Design

A retrospective case-control study conducted in a university-affiliated in vitro fertilization (IVF) unit.

Subjects

Women with PCOS undergoing IVF treatments and those with non-PCOS controls with tubal factor infertility only. Development morphokinetic milestones were compared and analysis of covariance for time to distinct cell number as well as logistic mixed models to determine predictors for embryos over the 75th percentile was performed.

Exposure

Not applicable.

Main Outcome Measures

Embryo development morphokinetic parameters in women with and without PCOS undergoing IVF treatments.

Results

The study included 791 embryos from 115 women, 364 embryos from 52 women with PCOS and 427 embryos from 63 women with non-PCOS controls with tubal factor infertility. The PCOS group was 4 years younger (30.07 ± 6.03 vs. 34.08 ± 4.84 years) and had higher number of oocytes retrieved (16.00 vs. 11.00), mature oocytes (11.00 vs. 7.00) and fertilized oocytes (8.00 vs. 5.00). The PCOS and control groups demonstrated comparable clinical pregnancy rates (55.8% vs. 32.1%), miscarriage rate (12.5% vs. 11.8%), and live birth rate (48.8% vs. 31.2%). Morphokinetic parameters were comparable between the groups. Although age was associated with later time to 5 and 8 discrete cells and start of blastulation (tSB), PCOS was only associated with later tSB, including tSB >75th percentile.

Conclusion

This study demonstrated comparable IVF outcomes in women with PCOS and non-PCOS controls. An analysis of time-lapse monitoring data from these patients showed no evidence that PCOS negatively affects embryonic development rate in women undergoing IVF cycles.
目的:应用延时监测系统(TLM)探讨多囊卵巢综合征(PCOS)与机械性(输卵管)因素不孕妇女胚胎发育速率的关系。设计:在一所大学附属试管婴儿单位进行的回顾性病例对照研究。患者:接受体外受精(IVF)治疗的多囊卵巢综合征(PCOS)妇女和仅伴有输卵管因素不孕的非PCOS对照者。对发育形态动力学里程碑进行了比较,并对不同细胞数量的时间协方差进行了分析,并对逻辑混合模型进行了分析,以确定超过75百分位的胚胎预测因子。暴露:不适用。主要观察指标:接受体外受精治疗的多囊卵巢综合征和非多囊卵巢综合征妇女的胚胎发育形态动力学参数。结果:该研究包括115名妇女的791个胚胎,52名多囊卵巢综合征妇女的364个胚胎和63名非多囊卵巢综合征妇女输卵管性不孕的427个胚胎。PCOS组比PCOS组年轻4岁(30.07±6.03岁比34.08±4.84岁,p=0.002),取卵数较高(16.00比11.00,p= 75百分位)。结论:本研究证明了多囊卵巢综合征和非多囊卵巢综合征对照妇女的IVF结果相当。对这些患者TLM数据的分析显示,没有证据表明多囊卵巢综合征对接受试管婴儿周期的妇女的胚胎发育率有负面影响。

Objective

To investigate whether endometrial receptivity is affected in patients with endometriosis using podocalyxin (PCX) as a functional biomarker and to study how endometriotic lesions display PCX and the potential pathological implications.

Design

We have previously reported that PCX, an anti-adhesion glycoprotein and barrier protector, is dynamically regulated in the endometrium and acts as a key negative regulator of epithelial receptivity. Early in the cycle both luminal epithelium (LE, lining the endometrial surface) and glandular epithelium (GE, residing within the tissue) strongly express PCX, but in the receptive window, PCX is selectively downregulated in LE, switching the endometrial surface to an adhesive state for embryo attachment/implantation; meanwhile, PCX expression is maintained in GE until postreceptivity. Here, we immuno-stained PCX in endometrial tissues and ectopic lesions biopsied across the menstrual cycle from patients with endometriosis (EOS, n = 41), and compared with endometrium of non-endometriosis controls (non-EOS, n = 55). We further investigated how PCX changes observed in ectopic lesions may influence their adhesive capacity.

Subjects

Women without and with endometriosis.

Exposure

Not applicable.

Main Outcome Measures

The window of endometrial receptivity might be shorter in patients with endometriosis; ectopic sites in addition downregulate PCX cyclically, mirroring the eutopic endometrial cells in preparing for receptivity to increase their adhesion potential.

Results

Endometrial PCX levels were comparable between non-EOS and EOS early in the cycle, and in both groups, PCX is downregulated in LE during the expected window of receptivity; however, in EOS endometrium, PCX is reduced earlier in GE as if the receptive window were shorter. In endometriotic lesions, PCX was detected in endometrial LE- and GE-like cells plus mesothelial cells enveloping peritoneal organs, but PCX was cyclically lost specifically in LE-like cells and reduced in GE-like cells as seen in the eutopic endometrium, which however may increase their adhesion potential to nearby organs (overlaid by mesothelial cells). This speculation was further corroborated in an in vitro model showing endometrial epithelial cells with lower PCX were indeed more adhesive to mesothelial cells.

Conclusion

Endometrial receptivity is subtly affected in patients with endometriosis with a shorter window. Cyclic downregulation of PCX in ectopic sites may have pathological consequences.
目的:探讨子宫内膜异位症患者子宫内膜容受性是否受足alyxin (PCX)功能标志物的影响;研究子宫内膜异位病变如何显示PCX及其潜在的病理意义。设计:我们之前报道过PCX,一种抗黏附糖蛋白和屏障保护器,在子宫内膜中受到动态调节,并作为上皮接受性的关键负调节因子。在周期早期,子宫内膜上皮(LE,衬在子宫内膜表面)和腺体上皮(GE,位于组织内)都强烈表达PCX,但在接受期窗口,PCX在LE中被选择性下调,将子宫内膜表面转换为胚胎附着/着床的粘附状态;同时,PCX在GE中的表达一直维持到接受后。在这里,我们对子宫内膜异位症患者(n=41)的子宫内膜组织和异位病变进行了免疫染色的PCX,并与非子宫内膜异位症对照组(n=55)的子宫内膜进行了比较。我们进一步研究了在异位病变中观察到的PCX变化如何影响其粘附能力。研究对象:无子宫内膜异位症和有子宫内膜异位症的女性。曝光:N / A。主要观察指标:子宫内膜异位症患者子宫内膜容受性窗口期可能较短;异位部位也周期性下调PCX,反映异位子宫内膜细胞为接受性做准备,以增加其粘附潜力。结果:子宫内膜PCX水平在周期早期在非EOS和EOS之间是相当的,在预期的接受窗口期间,两组的PCX在LE中下调,然而,EOS子宫内膜PCX在GE中较早降低,好像接受窗口较短。在子宫内膜异位症病变中,PCX在子宫内膜LE样细胞和ge样细胞以及包围腹膜器官的间皮细胞中检测到,但PCX在LE样细胞中周期性丢失,在异位子宫内膜ge样细胞中减少,但这可能增加了它们对附近器官的粘附潜力(被间皮细胞覆盖)。这一推测在体外模型中得到进一步证实,显示PCX较低的子宫内膜上皮细胞确实更能粘附间皮细胞。结论:短窗期子宫内膜异位症患者子宫内膜容受性受到微妙影响。异位部位PCX的循环下调可能有病理后果。

Objective

To establish a murine model of chemotherapy-induced diminished ovarian reserve (DOR) and investigate residual fertility after chemotherapy exposure.

Design

Two different chemotherapy protocols were tested to establish a valid DOR model by comparing follicle densities in mice given either protocol or physiological solution. An ovarian stimulation protocol was then selected from among different gonadotropins by counting the number of day 2 embryos obtained from normal mice. Finally, DOR mice were stimulated 5 and 8 weeks after chemotherapy with the chosen gonadotropin protocols, and day 2 embryos were recovered after mating, as was ovarian tissue for further immunohistologic analyses.

Subjects

Seventy-two Naval Medical Research Institute mice.

Exposure

Two different chemotherapy protocols.

Main Outcome Measures

This study compared day 2 embryo counts in both normal and chemotherapy-induced DOR mice. Ovarian histology and morphology were also investigated by follicle counting and classification, as was immunostaining for apoptosis (cleaved caspase-3), activation (phospho-Akt), and proliferation (Ki67).

Results

A dose of 12 mg/kg of busulfan (Bu) + 120 mg/kg of cyclophosphamide (Cy) was chosen to establish the DOR model as it significantly reduced the ovarian reserve compared to both control mice (physiological solution) and the 1.2 mg/kg of Bu + 12 mg/kg of Cy protocol, without depleting it completely. When stimulated with 3.75 IU of Menopur, normal mice produced significantly more embryos than DOR mice given 12 mg/kg of Bu + 120 mg/kg of Cy (41.40 ± 14.74 vs. 23.67 ± 15.55 day 2 embryos). Although the follicle count was statistically diminished after single-dose chemotherapy administration, the remaining follicles did not display any difference in terms of apoptosis, activation, or proliferation rates.

Conclusion

We successfully established a chemotherapy-induced DOR model using 12 mg/kg of Bu + 120 mg/kg of Cy, as evidenced by lower, but not completely depleted, follicle numbers and fewer retrieved embryos. Histologic study of ovarian tissue exposed to DOR-inducing chemotherapy revealed that surviving follicles were of the similar quality as tissue not exposed to chemotherapy.
目的建立化疗引起的卵巢储备功能减退(DOR)的小鼠模型,并研究化疗暴露后的剩余生育能力:设计:测试两种不同的化疗方案,通过比较两种方案中任一方案与生理溶液中小鼠的卵泡密度,建立有效的DOR模型。然后,通过计算正常小鼠第 2 天胚胎的数量,从不同的促性腺激素中选择一种卵巢刺激方案。最后,在化疗后5周和8周用选定的促性腺激素方案刺激DOR小鼠,交配后回收第2天胚胎和卵巢组织,以进一步进行免疫组织学分析:72只海军医学研究所(NMRI)小鼠:比较正常小鼠和化疗诱导的 DOR 小鼠的第 2 天胚胎数。还通过卵泡计数和分类对卵巢组织学和形态学进行了研究,并对凋亡(裂解的caspase-3)、活化(phospho-Akt)和增殖(Ki67)进行了免疫染色:与对照组小鼠(生理溶液)和1.2 mg/kg Bu + 12 mg/kg Cy方案相比,12 mg/kg Busulfan (Bu) + 120 mg/kg cyclophosphamide (Cy)剂量显著降低了卵巢储备功能,但并未完全耗尽,因此被选为建立DOR模型的剂量。在使用 3.75 IU Menopur 的刺激下,正常小鼠产生的胚胎数明显多于使用 12 mg/kg Bu + 120 mg/kg Cy 的 DOR 小鼠(第 2 天胚胎数为 41.40 ± 14.74 对 23.67 ± 15.55)。虽然单剂量化疗后卵泡数量在统计学上有所减少,但剩余卵泡在凋亡、活化或增殖率方面没有任何差异:结论:我们使用12 mg/kg Bu + 120 mg/kg Cy成功建立了化疗诱导的DOR模型,其表现为卵泡数量减少,但并未完全耗竭,取回的胚胎数量也较少。对暴露于DOR诱导化疗的卵巢组织进行的组织学研究显示,存活卵泡的质量与未暴露于化疗的组织相同。

Objective

Magnetic resonance elastography (MRE), a novel imaging technique that allows in vivo measurement of tissue mechanical properties, was used to test the prediction that the stiffness of the uterus may be increased due to fibrotic changes in patients with adenomyosis.

Design

A feasibility study in which a 3-dimensional (3D) MRE imaging protocol was developed to measure the stiffness of the tissues of the uterus.

Subjects

Four patients with suspected adenomyosis and heavy menstrual bleeding diagnosed via transvaginal ultrasound and clinical history and 1 healthy control were recruited. Two patients underwent hysterectomy, and histologic analysis of the tissue samples was performed.

Main Outcome Measures

The stiffness of the whole uterus was obtained by region of interest analysis of the 3D MRE images for the 4 patients and 1 healthy control. In addition, for the 2 patients who underwent hysterectomy, the uterine tissue samples were assessed to determine histologic presence of adenomyosis via hematoxylin and eosin staining, cellular/molecular measures of tissue stiffness (collagen [picrosirius red], α-smooth muscle actin, and e-cadherin), and whether a relationship existed between in vivo assessment of the uterus via 3D MRE and in vitro uterine tissue histology.

Results

3D MRE was successfully used to acquire elastograms for 4 patients with adenomyosis (diffuse, n = 3; focal, n = 1) and 1 healthy control. Calculated global uterine stiffness was higher in women with adenomyosis (2.93 kPa; range, 2.34–3.39 kPa) than in the healthy control (2.04 kPa). Regions of high stiffness on the 3D elastograms reflected adenomyotic changes visualized via conventional magnetic resonance imaging and were correlated with histologic and immunohistochemical markers of tissue stiffness.

Conclusion

3D MRE has the potential to provide non-invasive characterization of changes in the mechanical properties of uterine tissue that is not possible using conventional magnetic resonance imaging or transvaginal ultrasound. Further studies are needed to confirm the efficacy of the 3D MRE protocol for diagnosing adenomyosis.
目的:磁共振弹性成像(MRE)是一种新颖的成像技术,可以在体内测量组织力学特性,用于验证预测子宫僵硬度可能因子宫腺肌症患者的纤维化改变而增加。设计:一项可行性研究,其中开发了一种3D磁共振成像方案来测量子宫组织的刚度。对象:经阴道超声及临床病史诊断为血脑肿大伴重度月经出血(HMB)的患者4例,健康对照1例。2例患者行子宫切除术,并对组织样本进行组织学分析。主要观察指标:对4例患者和1例健康对照者的3D MRE图像进行感兴趣区(ROI)分析,获得全子宫僵硬度。此外,对两名接受子宫切除术的患者进行子宫组织样本评估,以确定(i)通过H&E染色确定子宫腺肌症的组织学存在,(ii)组织硬度的细胞/分子测量(胶原蛋白[微sirius红],α-平滑肌肌动蛋白,e-cadherin),以及(iii)通过3D磁共振在体子宫评估与体外子宫组织组织学之间是否存在关系。结果:4例子宫腺肌症患者(弥漫性n=3例,局灶性n=1例)和1例健康志愿者均成功应用三维磁共振成像获得弹性图。计算出的子宫总僵硬度在子宫腺肌症的女性中较高(2.93 kPa;范围2.34 - 3.39 kPa),而健康志愿者(2.04 kPa)。3D弹性图上的高硬度区域反映了常规MRI显示的腺肌病改变,并与组织硬度的组织学和免疫组织化学标志物相关。结论:3D MRE具有提供子宫组织力学特性变化的无创特征的潜力,这是传统MRI或经阴道超声无法实现的。需要进一步的研究来证实3D MRE方案诊断子宫腺肌症的有效性。

Objective

To determine if microRNAs that are altered in the circulation of women with endometriosis affect metabolic gene expression in hepatic cells.

Design

In vitro study.

Subjects

Deidentified tissue from women with endometriosis.

Exposure

MicroRNAs were used to induce or suppress target genes in hepatic cells.

Main Outcome Measures

Effect of the microRNAs that are aberrantly expressed in endometriosis on hepatic cell gene expression using quantitative polymerase chain reaction.

Results

Prior microarray studies on the serum of women with endometriosis showed differential expression of microRNAs miR-Let-7b, miR-125b-5p, miR-150-5p, and miR-3613-5p. Bioinformatic analyses revealed that these microRNAs have predicted binding sites in multiple genes involved in liver metabolism. Transfection of these miRs in HepG2 cells followed by real-time quantitative polymerase chain reaction showed that miR-Let-7b mimic increased the expression of Igfbp1 by 8-fold and reduced the expression of Mrc1 by 3.2-fold, whereas its inhibitor reduced Igfbp1 by 2.8-fold and increased Mrc1 by 5.2-fold. MiR-3613-5p mimic reduced the expression of Cyp2r1 by 2.2-fold and Mrc1 by 4-fold. MiR-125b-5p mimic increased the expression of Fabp4 by 4.1-fold, whereas miR-150-5p mimic increased the expression of Mrc1 by 1.8-fold and Cyp2r1 by 2.5-fold. Inhibitors of both miR-125b-5p and miR-150-5p did not show any effect on any of the genes.

Conclusion

Circulating microRNAs, known to be aberrant in endometriosis-regulated hepatic gene expression, likely contribute to the metabolic defects seen in this disease. Treatment with miR-Let-7b and miR-3613-5p, which are downregulated in endometriosis, reversed the effect of endometriosis on the expression of IGFBP1, MRC1, and CYP2r1 genes. Therefore, miR-Let-7b and miR-3613-5p may be novel candidate therapies for endometriosis, potentially correcting the metabolic changes seen in patients with endometriosis.
目的:确定子宫内膜异位症女性循环中改变的microrna是否影响肝细胞代谢基因表达。设计:体外研究。环境:学术医疗中心。人HEPG2细胞:在人HEPG2细胞中转染MiR-let-7b、miR-125b-5p、miR-150-5p和miR-3613-5p及其抑制剂或各自的对照。干预(s):使用microrna诱导或抑制肝细胞中的靶基因。主要结局指标:使用qpcr检测子宫内膜异位症中异常表达的microrna对肝细胞基因表达的影响。结果:先前对子宫内膜异位症女性血清的微阵列研究显示miR-Let-7b、miR-125b-5p、miR-150-5p和miR-3613-5p的microrna表达差异。生物信息学分析显示,这些microrna预测了参与肝脏代谢的多个基因的结合位点。在HepG2细胞中转染这些miRs后进行qRT-PCR显示,miR-Let-7b mimic使Igfbp1的表达增加了8倍(p = 0.004), Mrc1的表达减少了3.2倍(p = 0.003),而其抑制剂使Igfbp1的表达减少了2.8倍(p = 0.0004), Mrc1的表达增加了5.2倍(p = 0.04)。MiR-3613-5p mimic使Cyp2r1的表达降低了2.2倍(p= 0.04), Mrc1的表达降低了4倍(p= 0.0001)。MiR-125b-5p mimic使Fabp4的表达增加4.1倍(p = 0.020), miR-150-5p mimic使Mrc1的表达增加1.8倍(p = 0.01), Cyp2r1的表达增加2.5倍(p = 0.008)。miR-125b-5p和miR-150-5p的抑制剂对任何基因都没有任何影响。结论(s):已知在子宫内膜异位症中异常的循环microrna调节肝脏基因表达,可能导致该疾病中所见的代谢缺陷。在子宫内膜异位症中下调的miR-Let-7b和miR-3613-5p治疗可逆转子宫内膜异位症对IGFBP1、MRC1和CYP2r1基因表达的影响。因此,miR-Let-7b和miR-3613-5p可能是子宫内膜异位症的新候选疗法,可能纠正子宫内膜异位症患者的代谢变化。
