一、文言文原文（节选）
陈登者，字元龙，下邳淮浦人也。……年二十五，举孝廉，除东阳长，养耆育孤，视民如伤。是时，世荒民饥，州牧陶谦表登为典农校尉，乃巡土田之宜，尽凿溉之利，粳稻丰积。……
……太祖（曹操）每临大江而叹，恨不早用陈元龙计，而令封豕养其爪牙。后登在广陵，有威名。……孙权跨江攻登，登驰赴，设伏，纵火击之，贼遂大破。……登病，胸中烦懑，面赤，不食。佗（华佗）脉之曰：“府君胃中有虫数升，欲成内疽，食腥物所为也。”即作汤二升，先服一升，斯须尽服之。食顷，吐出三升许虫，赤头皆动，半身是生鱼脍也，所苦便愈。后如期发动，年三十九卒。
二、白话文翻译
生平概略
陈登，字元龙，是下邳郡淮浦县人。……二十五岁时，被推举为孝廉，任命为东阳县令。他奉养老人，抚育孤儿，爱护民众如同对待伤患。当时正值荒年，百姓饥馑，徐州牧陶谦上表推荐陈登担任典农校尉。于是他勘察适宜耕种的土地，充分发挥灌溉的便利，使得粳稻丰收，粮食储备充足。
军事才能与晚年
……曹操（太祖）每次来到长江边都会叹息，后悔没有早点采纳陈元龙的计策，以至于让孙权的势力像封豕（大野猪）一样养成了气候。后来陈登在广陵，声威显赫。……孙权渡江攻打陈登，陈登迅速率军迎敌，设下伏兵，放火攻击，大败敌军。……陈登生病，感到胸中烦闷，面色发红，吃不下东西。神医华佗为他诊脉后说：“太守您的胃里有数升虫子，快要形成内部的毒疮，这是吃生腥食物造成的。”随即配制了两升汤药，让陈登先服一升，过了一会儿全部服下。一顿饭的功夫，陈登吐出了大约三升的虫子，红色的头还在蠕动，虫子的半截身子还是生鱼片的模样，病痛随即就好了。但华佗说此病三年后还会复发，若遇良医则可救治。后来果然如期复发，当时华佗不在，无人能治，陈登三十九岁去世。
三、English Translation (Excerpts)
Biography of Chen Deng
Chen Deng, courtesy name Yuanlong, was a native of Huaipu in Xiapi commandery... At the age of twenty-five, he was recommended as a Filial and Incorrupt candidate and appointed as the chief of Dongyang County. He cared for the elderly and orphans, treating the people as if they were wounded. At that time, the world was in famine and the people were starving. Tao Qian, the Provincial Shepherd of Xu Province, recommended Chen Deng for the position of Commandant for Agriculture. Chen Deng then surveyed the suitable farmland, maximized irrigation benefits, and achieved abundant harvests of japonica rice...
...Whenever Emperor Cao Cao (Grand Ancestor) reached the great Yangtze River, he would sigh with regret for not adopting Chen Yuanlong's strategy earlier, thus allowing the enemy (like a great boar) to grow its fangs and claws. Later, when Chen Deng was in Guangling, he enjoyed high prestige... Sun Quan attacked Chen Deng across the river. Chen Deng rushed to meet him, set an ambush, attacked with fire, and thoroughly defeated the enemy... Chen Deng fell ill, suffering from chest irritation, a flushed face, and loss of appetite. Hua Tuo, after taking his pulse, said, “My lord, you have several liters of parasites in your stomach, about to form an internal abscess. This is caused by eating raw and spoiled food.” He then prepared two liters of medicinal decoction. Chen Deng first took one liter, and shortly after finished the rest. Within a mealtime, he vomited about three liters of parasites, with red heads still wriggling, half of their bodies appearing like raw fish slices. His suffering was then relieved. The illness later recurred as predicted, and with no skilled physician available, Chen Deng died at the age of thirty-nine.
四、历史评价与游戏关联
历史评价：陈登是东汉末年一位被低估的全才。在内政上，他劝课农桑，体恤百姓，是出色的地方官；在军事上，他两度击败孙策/孙权的进攻，稳固了曹操的东南边境；在外交上，他深谙纵横之道。其早逝是曹操集团的一大损失。
游戏关联：在以三国为背景的策略游戏（如《三国志》系列、《国宝三国》等）中，陈登通常被设定为一名政治、智力属性较高，并拥有“筑城”、“商才”、“诡计”等特技的武将或文官，反映了其治理与谋略方面的才能。了解其真实历史生平，能帮助玩家在游戏中更好地理解与运用这一角色。
