概括
与芳香酶抑制剂相比,丸激素治疗显著提高了青春期延迟的男孩的骨形成和骨矿物质含量积累. 短期使用芳香酶抑制剂不会损害骨积累,但长期影响仍然未知.

- 儿科内分泌学 儿科内分泌学
- 骨的新陈代谢 骨的新陈代谢
- 青春期发展 青春期发展
背景情况:
- 延迟青春期 (DP) 需要治疗以确保骨的正常发育.
- 通过芳香酶抑制剂 (AIs) 或 (T) 来诱导不同的荷尔蒙环境,以研究性类固醇在骨中的作用.
- 对儿科患者来说,评估这些治疗对骨代谢的影响至关重要.
研究的目的:
- 为了比较低剂量 (T) 与芳香酶抑制剂莱特 (Lz) 对DP男孩骨代谢的影响.

主要方法:
- 一项前性随机对照试验,涉及27名患有PD的男孩.
- 男孩接受了六个月的莱特 (Lz) 或低剂量的 (T).
- 边缘定量计算断层扫描 (pQCT) 和骨状况标志物在基线和随访间隔进行了评估.
主要成果:
- 与莱特相比,治疗导致骨形成标记物 (P1NP,BAP) 和骨矿物质含量 (BMC) 在远距离部积累的增加.
- 在两组中,水平的变化与距离半径的BMC变化呈正相关.

01:27Signs of Puberty
610
Puberty is a critical phase, typically beginning between the ages of 8 and 13 in girls and 9 and 14 in boys, though timing can vary based on genetics, environmental factors, and overall health. This period is characterized by the development of secondary sexual characteristics and the attainment of reproductive potential. Endocrine changes underpin puberty, with hormonal surges of Luteinizing Hormone (LH) and Follicle-Stimulating Hormone (FSH) instigated by Gonadotropin-Releasing Hormone (GnRH)...

01:29Bone Disorders
3.9K
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

01:17Hormones and Bone Tissue
2.9K
The endocrine system produces and secretes hormones, which interact with the skeletal system. These hormones control bone growth, maintain bone once it is formed, and remodel it.
Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...

01:40Bone Remodeling
38.5K
Bone remodeling is a continuous and balanced process of bone resorption by osteoclasts and bone formation by osteoblasts. In adults, it helps maintain bone mass and calcium homeostasis. While mechanical stress can stimulate turnover as part of the normal maintenance and reparative process, several hormones also regulate bone remodeling.

01:10Nature and Nurture
20.8K
Many human characteristics, like height, are shaped by both nature—in other words, by our genes—and by nurture, or our environment. For example, chronic stress during childhood inhibits the production of growth hormones and consequently reduces bone growth and height. Scientists estimate that 70-90% of variation in height is due to genetic differences among individuals, and 10-30% of variation in height is due to differences in the environments that individuals experience,...
