概括
急性肌肉骨损伤,如手腕骨折,降低维生素D结合蛋白 (VDBP) 水平. 然而,这些变化并没有影响患者的维生素D水平,这表明目前的测量可能并不完全反映维生素D状态.
科学领域:
- 生物化学 生物化学
- 内分泌学 在内分泌学.
- 整形外科 整形外科 整形外科
背景情况:
- 维生素D结合蛋白 (VDBP) 携带维生素D (VD),其水平随着炎症而波动.
- 众所周知,系统性炎症会改变VDBP水平.
- 急性肌肉骨损伤对VDBP和VD水平的影响尚不清楚.
研究的目的:
- 调查急性肌肉骨损伤对VDBP水平的影响.
- 为了确定VDBP水平的变化是否会影响受伤后的维生素D状态.
- 为了比较手腕骨折患者与健康对照患者的VDBP和维生素D水平.
主要方法:
- 测量了血清VDBP,自由的25(OH) D和总的25(OH) D.
- 研究了两个年龄相匹配的女性组:手腕骨折患者 (n=35) 和健康的志愿者 (n=35).
- 统计分析比较了组,并评估了测量之间的相关性.
主要成果:
- 与健康志愿者相比,手腕骨折组的VDBP水平明显较低 (p < 0.001).
- 自由含量和总含量25 (OH) D在两组之间没有显著差异.
- 自由和总25~OH) D之间的相关性在健康对照组中很强 (R=0.885),但在骨折患者中中度 (R=0.605).
结论:
- 急性肌肉骨损伤导致VDBP水平降低.
- 受伤后降低的VDBP水平并没有改变自由维生素D或总维生素D水平.
- 需要进行进一步的研究,以确定总数25(OH) D是否准确地反映了骨折患者的静脉疾病状态.

01:25Role of Vitamins in Maintaining Bone Health
3.7K
The growth and maintenance of bone are regulated by a combination of nutritional factors, including vitamins, such as vitamin A, B12, C, D, and K.
Vitamin A
Vitamin A is involved in the process of bone remodeling. Retinoic acid, the active metabolite of Vitamin A, has nuclear receptors in osteoblasts and osteoclasts, which are involved in bone remodeling.
Vitamin B12
Vitamin B12 acts as a cofactor during the formation of osteoblast-related proteins, such as osteocalcin. Vitamin B12 plays a role...

01:23Role of Skin in Vitamin D Synthesis
5.6K
The skin plays a crucial role in the synthesis of vitamin D, a vital nutrient for various physiological processes in the body. Vitamin D is unique because it can be synthesized in the skin through a series of chemical reactions triggered by exposure to ultraviolet B (UVB) radiation from sunlight.
The solar UV B rays (290-315 nm) are absorbed by the skin, and 7-dehydrocholesterol (provitamin D3) photolyzes it to previtamin D3, which undergoes a rapid transformation to vitamin...

01:21Skeleton and Calcium Homeostasis
4.8K
Calcium is not only the most abundant mineral in bone but also the most abundant mineral in the human body. Calcium ions are needed for bone mineralization, tooth health, heart rate regulation and strength of contraction, blood coagulation, the contraction of smooth and skeletal muscle cells, and the regulation of nerve impulse conduction. The average calcium level in the blood is about 10 mg/dL. When the body cannot maintain this level, a person will experience hypo or hypercalcemia.

Protein-drug binding, a pivotal aspect of pharmacokinetics, is subject to considerable variability influenced by an array of patient-related factors. The intricate interplay of age, individual differences, and pathological conditions significantly impact the binding dynamics and subsequent pharmacological effects.
Age stands as a key determinant in protein-drug binding. Neonates, characterized by low albumin content, experience heightened concentrations of unbound drugs such as phenytoin and...

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...

Drug binding to proteins is a key aspect of pharmacokinetics and can influence a drug's distribution, absorption, and elimination in the body. Several factors, including the drug's physiochemical properties, protein concentration, disease states, and the number of binding sites on the protein, influence this process.
The physicochemical properties of a drug play a significant role in its ability to bind to proteins. Lipophilic drugs, which dissolve in fats, oils, and lipids, can be...
