之前西楚国投降越国的将领们都纷纷请命参战，一时间越军可以为师人才济济，声势浩大。1948年，高级特工燕文川带着重大秘密任务回到家乡江城，刚进家门，便遭遇了一场惊心动魄的劫难，无意中让燕文川成为国共两党秘密斗争的中心人物。 然而，即便是当地党组织也不知道燕文川的真实身份。为了保密，地下党决定暂时将他扣押，并且把这颗烫手的山芋交给了一名刚从苏联留学回来“小燕子”式的年轻女干部窦婉茹。窦婉茹因此进驻到燕家，假扮燕文川的保姆，时刻监视他的一举一动，但因为冲动，她经常不小心会暴露自己。 同时，在同学娄海平一再推荐下，江城军统站长陈恭如因为爱惜人才，强行将燕文川招入军统。流浪的孤儿、街头变色龙Sarah目睹一个女人自杀后决定假冒死者的身份领取一笔数目可观的存款。凑巧的是，Sarah和死者的长相颇为相似。然而Sarah万万没有想到，自己竟然一脚踏进了一个危险的谜局。死者是一名正在接受内部调查的警察，这意味着Sarah必须装模作样地当好一个警察，还必须随时接受对她来说毫无头绪的盘问。最终Sarah发现了一个惊人的事实：她和自杀的女警察都是克隆人，而且这批克隆人绝不止她们两个。有关方面为了达到不可告人的目的，创造了一批克隆的胚胎并将她们植入毫不知情的普通夫妻体内，让她们在不同的环境中出生、成长。没有人知道是谁创造了这些克隆人，也没有人知道他们的最终目的。这些克隆人必须尽快查明真相，否则一切都晚了，一名不知身份的刺客正在一个接一个地谋杀她们。Thromboembolic diseases are currently one of the causes that endanger human health and lead to the highest mortality rate, such as myocardial infarction, cerebral thrombosis, deep vein thrombosis, cerebral embolism, pulmonary embolism, etc. In addition, thrombosis is an important pathological process involved in the pathogenesis of many diseases. 1. Anticoagulant therapy (1) Heparin: Heparin is a commonly used anticoagulant and is a highly sulfated glucosaminoglycan. Heparin is widely found in mammalian tissues, and mast cells are the main producing sites. The main sources of medicinal heparin are bovine lung and pig intestinal mucosa. Heparin used clinically is called unfraction heparin (UFH) because it is a mixture of components with different relative molecular weights. The relative molecular weight is between 33,000 and 30,000, which is also called standard heparin (SH). The drug name is heparin sodium. (2) Low molecular weight heparin: crude heparin is cracked into some fraction with relative molecular mass of 1000 ~ 12000 by chemical or enzymatic hydrolysis methods, and then purified. There are at least 10 kinds of low molecular weight heparin prepared by different manufacturers and different methods.故事发生在非洲附近的大海上，主人公冷锋遭遇人生滑铁卢，被“开除军籍”，本想漂泊一生的他，正当他打算这么做的时候，一场突如其来的意外打破了他的计划，突然被卷入了一场非洲国家叛乱，本可以安全撤离，却因无法忘记曾经为军人的使命，孤身犯险冲回沦陷区，带领身陷屠杀中的同胞和难民，展开生死逃亡。随着斗争的持续，体内的狼性逐渐复苏，最终孤身闯入战乱区域，为同胞而战斗。
