SCI醫(yī)學論文翻譯是醫(yī)學科學研究工作的書面記錄與文字總結(jié)得出來的論文，是醫(yī)學科學研究工作無法缺少的重要部份, 是目前學歷、學位、晉升職稱的必需條件。因此，寫出一個涵義準確、清楚、文字精簡且不乏味的英文SCI醫(yī)學論文翻譯是件較有挑戰(zhàn)性的事情，譯員需要有相較不錯的英語寫作能力跟醫(yī)學背景， SCI醫(yī)學論文翻譯基本要求是：清楚、準確、簡潔和生動。

SCI醫(yī)學論文翻譯案例：

Gene therapy was introduced in treatment of Hepatitis C since molecular biological techniques have developed, and the pathogenesis of Hepatitis C has been gradually made clear. To choose a highly-effective, specific, and safe hepatic-targeting gene vector is the key to the success of genetic treatment of hepatic disease. Recently, cationic polymer is extensively applied for its stability, being easy to modify, and low immunogenicity, especially the polyvalent cationic polymer polyethyleneimine (PEI), which can be degraded in physiological environment [1-3]. Chitosan (CS), a natural polycation gene vector has attracted extensive attention [4，5].  In PET/CS induced hepatic-targeting gene introduction, actively recognizing and endocytosing the transfection compound containing its specific ligand through asialoglycoprotein receptor (ASGP-R) is the major mechanism of improving the efficiency of the gene transference. Also it is a receptor-mediated gene transference system which is widely studied at present.

In this research we grafted the low-molecular-weight PEI (2K) to galactosylated chitosan following the documents [6], and synthesized galactosylated chitosan- polyethyleneimine (2K) (GC-PEI), studies the targeting of GC-PEI/DNA complex in hepatic cell lines (L02, QSG7701 and QSG7701/core) and hepatic cell in mouse. To optimize the transfection efficiency of gene vectors, we synthesized GC-PEI/DNA complexes in three different solvents, and selected appropriate gene vectors for experiment in vitro and in vivo.
