【医学ppt课件】 贫血(Anemia)
鐮刀型貧血（Sickle-Cell Anemia）
血紅素本身又是由四個蛋白質分子α1、α2、β1、β2拼 湊起來的，而這每一個小單位，都各自有一個鐵化合物 （heme、血鐵質）在蛋白質的中心，負責與氧結合。
如果β2蛋白的第六個胺基酸（蛋白質的組成分子）發生突 變，β2蛋白的結構會產生變化，進而影響到血紅素的整體 構造與功能。不但不能載氧，更會與鄰近的血紅素聚集成 一條條棍子狀的結晶。
重度的β地中海貧血胎兒出生時並無症狀，一個月 後嬰兒才出現貧血、黃疸、脾臟腫大。重度的乙 型患者自此即需終身輸血才能度日，否則五歲左 右即因心臟衰竭死亡。 中度的患者血色素常能保持7-10公克左右。此類 病患不需輸血仍可存活，但因長期處於持續且輕 微的缺氧狀態，刺激骨髓增生作為代償，長期會 顯現額骨突出、兩側骨高、上鄂骨外突使門牙外 露、形成一大特徵，此被稱作地中海貧血面容。
鐮刀型血球會阻塞血管，造成疼痛、 心臟衰弱、風濕症等。此種因一個基 因改變，造成多種性狀的變化，遺傳 學上稱為基因多效性(Pleiotropy)]
治療與展望
地中海貧既然是遺傳性造血障礙，當然可以利用骨髓 移植來治療，患者若有吻合的親屬捐髓者時，即可進 行。地中海貧血患者骨髓幹細胞移植行之多年，是目 前唯一的根本治療法。（但仍無助於缺陷基因及遺傳 的矯正）
幹細胞移植祇能治療地中海貧血患者先天性的造血缺 憾，但對病程續發的併發症如鐵質存積、脾臟腫大及 紅血球抗體產生並無任何助益，故患者應及早接受移 植，以免併發症已形成，影響移植療效。
當α基因病變時所造成的貧血，就稱為α地中海貧血， 國人亦稱作甲型地中海貧血。同樣也會有β地中海貧 血，國人亦稱作乙型地中海貧血。我國是甲型地中 海貧血好發區，發生率較乙型高（約3:1，全國約 6%的人有地中海貧血基因）。 而一般所說的重症海洋性貧血就是指「β重型海洋性 貧血」，它又叫做庫利氏貧血，是β血紅蛋白鏈合成 嚴重的不足。

孕妇营养性贫血的预防与治疗
详细描述
孕妇营养性贫血是由于孕期对铁、叶酸等营养素需求增加而摄入不足引起的贫血。预防和治疗孕妇营 养性贫血的关键是提供富含铁、叶酸等营养素的食物，如瘦肉、绿叶蔬菜等，并定期进行产前检查和 筛查。

Overview of Nutritional America
Definition
Nutritional anemia is caused by a lack of certain essential nutrients, such as iron, folate, or vitamin B12, leading to insufficient hemoglobin synthesis and resulting in anemia.
Improving diet
Ensure that the diet contains sufficient nutrients such as iron, folate, and vitamin B12 to increase hemoglobin synthesis.
