背景情况:
- 甲状腺激素 (prolactin) 影响乳腺发育,可能在乳腺癌中起作用.
- 此前关于益乳素和乳腺癌的研究受到小样本大小和缺乏详细分析的限制.
- 了解益乳素的作用对于评估乳腺癌风险至关重要.
研究的目的:
- 调查血前素度与患绝经后乳腺癌的风险之间的关联.
- 通过已知的乳腺癌风险因素来探索这种关联的潜在影响修改.
主要方法:
- 分析了四项前性队列研究中8,279名绝经后妇女的数据.
- 使用ELISA测定对诊断前采集的血样本进行益生菌水平的测量.
- 聚合后勤回归模型被用来估计乳腺癌风险的几率比率 (OR).
主要成果:
- 升高的益生菌度 (>13.2 ng/mL) 与更年期后乳腺癌风险增加有显著关联 (OR:1.20).
- 这种关联在目前使用绝经后激素治疗的女性中尤为明显 (OR: 1.58).

138
Menopause, a natural biological process marking the end of a woman's fertility, typically occurs between the fifth and sixth decade of life. This phase is characterized by the exhaustion of the ovarian follicle pool, leading to less responsive ovaries despite the high levels of Follicle Stimulating Hormone (FSH) and Luteinizing Hormone (LH). The consequential decrease in estrogen production results in symptoms like hot flashes, heavy sweating, headaches, hair loss, muscle pains, vaginal...

The female reproductive system can be affected by several disorders, including Premenstrual Syndrome (PMS), Premenstrual Dysphoric Disorder (PMDD), endometriosis, and various forms of cancer. PMS and PMDD are cyclical conditions that cause physical and emotional distress, with symptoms that include edema, mood swings, and food cravings. PMDD is a more severe form of PMS characterized by increased symptom severity that peaks during the luteal phase and tends to improve or resolve shortly after...
