解冻单囊胚形态评分与早期血清β-人绒毛膜促性腺激素浓度和活产的相关性

Zhongshan Daxue xuebao. Yixue kexue ban, 2023
目的在解冻单囊胚移植后HCG阳性患者中，评估囊胚形态评分对第 12 天血清β-人绒毛膜促性腺激素（β-hCG）水平和活产结局的影响；分析血清β-hCG 水平对活产的预测价值。方法回顾本院2016年1月至2020年5月的519个单囊胚激素替代治疗-冻融胚胎移植（HRT-FET） 周期HCG阳性患者的数据。先根据Gardner 囊胚分级分为4组（AA、AB、BA和BB）；再根据囊腔扩张程度分期分为4组（3期、4期、5期、6期，Gardner 评分）。比较不同分级和分期的囊胚移植后第 12 天的血清β ...

Towards the Development of a Conceptual Framework of the Determinants of Pre‐eclampsia: A Hierarchical Systematic Review of Biomarkers

BJOG: An International Journal of Obstetrics &Gynaecology, EarlyView.
ABSTRACT Background Pre‐eclampsia is a leading cause of maternal and perinatal morbidity and mortality. There are several determinants of individual pregnant women's risk of developing pre‐eclampsia, including biomarkers and ultrasound markers. Objective A conceptual framework to collate and summarise the extensive body of literature on biomarkers ...

胎膜早破阴道后穹窿冲洗液β-hCG测定 附视频

Zhongguo shiyan zhenduanxue, 1999
探讨阴道后穹隆冲洗液β-hCG水平测定对于诊断胎膜早破(PROM)的意义。方法 采用放射免疫法测定30例胎膜早破孕妇(胎膜早破组)和60例正常孕妇(对照组,其中30例妊娠28～32周为对照组1,30例妊娠36～42周为对照组2)后穹隆冲洗液(3ml无菌生理盐水)β-hCG水平。结果 胎膜早破组后穹窿冲洗液β-hCG测定结果为324.82mlU/ml,观察组后穹窿冲洗液β-hCG测定结果为5.36mlU/ml,观察组后穹隆冲洗液β-hCG水平明显高于对照组,差异有显著性(P0.05)。结论 ...

Testicular histopathology and its association with germ cell numbers, serum concentrations of reproductive hormones, and semen quality

Andrology, EarlyView.
Abstract Background It is well‐established that spermatogenesis, semen quality, and reproductive hormones are interlinked. It is, however, less well‐described how various specific testicular histopathologies are linked to reproductive hormones and semen quality.

Semen quality in patients with testicular cancer is associated with age and with greatly elevated levels of beta human chorionic gonadotropin

Andrology, EarlyView.
Abstract Background Poor semen quality is a well‐known feature in patients with testicular germ cell tumours (GCTs) at the time of diagnosis but the underlying biological reasons are incompletely understood. Objectives This study aimed to identify GCT‐specific clinical factors that are involved with poor semen quality in GCT patients.

Hyperthyroidism induced by paraneoplastic human chorionic gonadotropin (hCG) production from testicular tumours: a retrospective clinical and histopathological study

Endocrine Connections
Human chorionic gonadotropin (hCG) has structural similarities with thyroid-stimulating hormone (TSH) and may stimulate TSH receptors at higher concentrations. During pregnancy, placental hCG causes TSH suppression, contributing to hyperemesis.

Identification of MEF2A, MEF2C, and MEF2D interactomes in basal and Fsk‐stimulated mouse MA‐10 Leydig cells

Andrology, EarlyView.
Abstract Background Myocyte enhancer factor 2 transcription factors regulate essential transcriptional programs in various cell types. The activity of myocyte enhancer factor 2 factors is modulated through interactions with cofactors, chromatin remodelers, and other regulatory proteins, which are dependent on cell context and physiological state.

Cryopreservation of Spermatozoa Prior and Post‐Orchiectomy in Patients With Testicular Germ Cell Cancer—Does the Timing Matter?

Andrology, EarlyView.
ABSTRACT Background Testicular germ cell cancer (TGCC) is the most frequent malignancy in young men of reproductive age. According to guidelines, semen cryopreservation should be performed prior to orchiectomy. Lack of time and local facilities as well as mental pressure are challenges in terms of fertility preservation before surgery.
