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 ...

Microtubule Inner Protein CFAP77 Contributes to Sperm Motility and Male Fertility in Mice
Andrology, EarlyView.ABSTRACT Background Sperm motility is essential for male fertility, and its regulation is dependent on the structural integrity of the axoneme. The axoneme consists of a conserved “9+2” microtubule arrangement and is supported by microtubule inner proteins. However, the functional significance of many microtubule inner proteins remains unclear.

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.

A Unified Machine Learning Model for Relapse Prediction in Clinical Stage I Testicular Cancer
Andrology, EarlyView.ABSTRACT Background Approximately one‐fourth of patients with clinical stage I testicular cancer relapse. For decades, risk stratification has been based on different tumor characteristics for seminomas and non‐seminomas. Previous studies primarily used Cox proportional‐hazards models and included only a limited number of variables.

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 ...

Andrology, EarlyView.ABSTRACT Background Testicular germ cell tumours (TGCTs) are the most common type of tumour diagnosed in young men, and reliable non‐invasive biomarkers are crucial for clinical management. MicroRNAs (miRNAs) from the miR‐371–373 cluster have recently been identified as novel and more sensitive serum biomarkers than the conventional protein‐based ...
