自己對病理這個科目有種愛恨交織的感受 在大三以前我都聽說病理就是不正常的生理 其實那應該只是病理的病生理的部分而已 所以說病理到底都在學什麼啊？ 應該要先從認識疾病開始，一個疾病的特色有哪些？ Epidemiology 這個疾病的危險因子有哪些？比如說抽煙喝酒肥胖等等。男生比較容易得還是女生比較容易得？比較容易兩側都長還是單側長？是否有地區、季節性分布或是常見在一些族裔的人身上？ Genetics 有些疾病是由一些特定基因變異、染色體異常造成的。也有些疾病後來研究發現常見有某些特別的基因變異。這些基因上的特徵讓我們對疾病可以有更精準的診斷、預後(比如說影響治療方式跟存活率)。 造成疾病的根本因素也不一定是基因變異，有的時候是內分泌或是表關遺傳的因素(比如說silencing)造成的，或者是感染、自體免疫反應等等，總之有不少疾病有這樣的根源，臨床上有其重要性，考試也很愛考。 Gross 巨觀上發生疾病的器官、系統會有什麼樣的變化。像台大會有專門的病理解剖討論課讓大家感受這樣的標本，也有拿實際標本考的跑台考試(有些可能是第一次看到，或是最近手術切下來的東西)，讓大家知道疾病不只是課本上那些基因或是玻片，在病人實際的器官上可以看到病灶。 Micro 這應該是病理醫師的本領，就是看切片見微知著地知道這是什麼疾病。顯微鏡下的特徵，比如說組織類型、結構、細胞學型態等等，在台大會考玻片跑台，要能夠寫下診斷跟特徵，不過首先...器官要寫對。Micro是一個我很不在行的考試...總覺得這麼困難的工作還是給AI處理好了...有的時候因為光用雙眼還是分不太出來，會用免疫染色染細胞上特別的蛋白質或構造，或是用電子顯微鏡看更細微的變化，總之就是...一沙一世界... Pathophysiology 病生理是我覺得很有趣的一部分，也是相對需要邏輯沒那麼需要背的。一個疾病從他的根源，比如說一個基因突變，可以在不同器官上產生很特別的變化(通常這叫pleiotropy)，那從基因到Gross跟Micro之間發生了什麼事情，身體發生了什麼改變造成臨床上看到的表現，就是病生理的故事。不過因為醫學研究目前的知識還是有限，不見得所有病生理的解釋都全然正確，很多都是假說。但多看點病生理的好處是能幫助記憶也讓病理沒那麼難以下嚥？ 感覺在學校通常重視的是基因跟分子上的變化和Micro的特徵，偶爾考一下永遠搞混的流行病學，但跟臨床與病生理就有段距離需要自己補足。 我在學期中的時候看了一本複習書BRS pathology，在另一本美國很有名的複習教材Pathoma出現前他是滿主流的教材。BRS跟Pathoma提到的疾病往往分類跟分子上的深度遠不及台大的病理學課程，所以對準備區段考可能沒什麼幫助，但我覺得看那樣的書因為會對於病生理跟臨床表現比較有印象，在臨床課還是可以用得到，加上可以很快地掌握一個器官系統大概有哪些疾病，可以建構一次區段考初步架構XD 另一方面，台大病理教的東西因為很深，深到跟國考愛考的東西很像(往往是病理學聖經本Robbins上面的一句話)，所以我現在覺得熟讀台大病理拿來準備國考是相當足夠的！ #pathology #medicine #epidemiolgy #medicalstudent #台大 #醫學 #醫學系 #醫學生 #病理 #解剖 #生物 #學習 #教材
