維他命在臨床上的重要性與檢測

目的：維他命在人體中參與多種生化反應和代謝調節，它能促進蛋白質、糖和脂肪的合成，還有促進生長發育，提高免疫力，延緩衰老等生理機能。每種維他命都有其特殊的功效，一旦缺乏或服用過量時，進而產生疾病或毒性，嚴重的可引致死亡。本文探討維他命不足或過量時與疾病的相關性，以及現時實驗室對維他命的測量方法和檢測項目，為臨床診斷或治療提供準確可靠的依據。方法：以文獻回顧的形式重點探討維他命B1、B2、B6、葉酸、B12、維他命C、維他命D及維他命E在人體缺乏或攝取量不足與心血管疾病、神經病變、糖尿病、癌症的關係，以及濫用維他命對健康所帶來的後果。結論：目前維他命暫時沒有充夠的證據在預防或治療疾病方面有顯著的效果。然而維他命在藥物治療和人類腸道菌群有新的發展和研究。

Objectives: Vitamins are involved in a variety of biochemical reactions and metabolic regulation in the human body, which can promote the synthesis of proteins, sugars and fats, as well as promote growth and development, enhance immunity, delay aging and other physiological functions. Each vitamin has its own special effect, once it is deficient or overdose, it can cause disease or toxicity, which can lead to death. This paper explores the correlation between vitamin deficiency or overdose and disease, as well as current laboratory measurements of vitamins, to provide an accurate and reliable basis for clinical diagnosis or treatment. Methods: Literature review focus on the relation between B1, B2, B6, folic acid, B12, vitamin C, vitamin D and vitamin E deficiency in the human body deficiency or insufficient intake and cardiovascular disease, neuropathy, diabetes, cancer, and the consequences of vitamin abuse on health. Conclusions: There is no enough evidence of vitamins to have a significant effect on the prevention or treatment of diseases. However, vitamins have new developments and studies in drug therapy and human intestinal microbiota.
