摘要:

文题释义:
组织工程:应用生命科学与工程学的原理与技术,在正确认识哺乳动物的正常及病理状态下的组织结构与功能关系的基础上,研究、开发用于修复、维护、促进人体各种组织或器官损伤后的功能和形态的生物替代物的一门新兴学科。

背景:组织工程学发展具有极大的社会价值和经济效益,评估和分析中国在组织工程热点子领域的基础研究实力,将有助于优化资源配置和制定适宜的发展策略。

目的:评价中国在组织工程热点子领域的基础研究实力。

方法:在PubMed数据库中检索全球、美国和中国在组织工程热点子领域(包括骨和软骨、神经、血管、肝脏、皮肤、心脏、眼组织工程)的基础研究论文和顶尖基础研究论文。以全球和美国为背景,基于论文数量、论文增速、顶尖论文数量及比例,分析中国在组织工程热点子领域的基础研究实力。

结果与结论:①中国在骨和软骨组织工程、神经组织工程、血管组织工程、肝脏组织工程、皮肤组织工程、心脏组织工程和眼组织工程领域的基础研究论文数量依次为4 487,3 551,2 869,1 328,1 185,1 088和689篇,占全球发文量的10%-15%之间,其中,前5个子领域的发文量约为美国的一半,心脏组织工程和眼组织工程领域的发文量仅分别为美国的32.1%和37.8%;②中国在上述各子领域的论文量增速分别为19.3%,19.5%,18.2%,14.6%,21.8%,19.6%和19.6%,均远超全球和美国;③中国在上述各子领域的顶尖基础研究论文数依次为36,31,33,24,15,24和12篇,顶尖论文比例依次为0.8%,0.9%,1.2%,1.8%,1.3%,2.2%和1.7%,明显低于全球平均水平和美国;④结果表明,中国在骨和软骨、神经组织工程、血管组织工程3个子领域的基础研究规模相对较大,而在心脏、眼2个子领域的基础研究规模相对较小;中国在各子领域的基础研究规模增速均超过全球和美国,且增速优势明显;中国在各子领域均有一定数量的顶尖基础研究成果,但顶尖成果比例比起全球和美国而言还有较大提升空间。

Abstract:

BACKGROUND: Development of tissue engineering is of great social and economic significance. Understanding the basic research strength of China in the main subfields of tissue engineering can provide reference for the optimization of resources allocation and for the formulation of corresponding development strategies.

OBJECTIVE: To evaluate the basic research strength of China in the main subfields of tissue engineering. 

METHODS: PubMed was searched for basic research and top basic research articles in the subfields of tissue engineering (including bone and cartilage, nerve, blood vessel, liver, skin, heart, and eye tissue engineering) in the world, the United States and China. By comparing with the global average and American, Chinese basic research strength in the main subfields of tissue engineering was evaluated with indicators including the number of papers, the growth rate of papers, and the number and proportion of top papers. 

RESULTS AND CONCLUSION: (1) The number of basic research papers published by Chinese institutions in the subfields of bone and cartilage tissue engineering, nerve tissue engineering, vessel tissue engineering, liver tissue engineering, skin tissue engineering, cardiac tissue engineering and eye tissue engineering was 4 487, 3 551, 2 869, 1 328, 1 185, 1 088 and 689, respectively, accounting for 10%-15% of worldwide papers in corresponding subfields. The amount of papers published by Chinese institutions was nearly half of that published by institutions of the United States for the first five subfields, but only 32.1% and 37.8% of that published by institutions of the United States for the latter two subfields. (2) The annual growth rate of papers published by Chinese institutions was 19.3%, 19.5%, 18.2%, 14.6%, 21.8%, 19.6% and 19.6%, respectively, for the above seven subfields, all of which were obviously higher than that of the global average and the United States. (3) The number of top papers published by Chinese institutions was 36, 31, 33, 24, 15, 24 and 12, and the proportion of top papers published by Chinese institutions was 0.8%, 0.9%, 1.2%, 1.8%, 1.3%, 2.2% and 1.7%, respectively, all of which were obviously lower than that of the global average and the United States. (4) China has published relatively more papers on bone and cartilage tissue engineering, nerve tissue engineering and vessel tissue engineering, and relatively less papers on cardiac tissue engineering and eye tissue engineering. The amount of papers published by Chinese institutions has been growing rapidly in each of the seven main subfields of tissue engineering, with the speed of growing being obviously higher than that of the global average and the United States. China has published a certain amount of top papers in each of the seven subfields, while the proportion of top papers for China is obviously lower than that of the global average and the United States. 

Key words: tissue engineering, basic research, research strength, scientific paper, bibliometrics, subfields of tissue engineering
