Diabetic nephropathy research in China: Data analysis and review from the National Natural Science Foundation of China中国糖尿病肾病研究现状：对中国国家自然科学基金数据的回顾性分析

As the largest funding agency of natural science of China, the National Natural Science Foundation of China (NSFC) has made great efforts in promoting the development of diabetic nephropathy (DN) research in recent years. The aim of the current study is to summarize the diabetic nephropathy research in China by analyzing NSFC-funded projects. Data on all projects in the DN field funded by NSFC from 1986 to 2013 were collected. The funding tendency, funding areas, and hotspots in the DN field, and major research institutions, were analyzed. As one output of this support, outstanding research groups in China, and their representative studies, are also highlighted. From 1986 to 2013, the NSFC has funded a total of 248 projects in the DN field, with a total funding amount of 91.5 million RMB (US$14.9 million). A rapid increase could be seen in the past 5 years, with an average annual 30% increase in projects numbers and a 52% increase in funding amount. All fields in DN research have been covered by the NSFC, including etiology, pathophysiology, diagnostics, and therapeutics. Along with increased funding of the DN research, there has been a growth in the papers published in Science Citation Index journals by Chinese scholars. In the past decade, the funding scale and funding budget have increased dramatically. Benefiting from this, DN research in China has also made considerable progression. 摘要 国家自然科学基金委员会（the Natural Science Foundation of China，NSFC）作为中国最大的自然科学资助机构，在促进糖尿病肾病（Diabetic Nephrology，DN）研究方面做出了巨大努力。本文旨在通过分析NSFC成立以来资助的项目来概述中国近年糖尿病肾病研究的现状。 本文收集了自1986年至2013年，NSFC所资助的所有DN研究领域的科研立项的基本数据。总结分析了NSFC在该领域的资助趋势、资助领域和热点以及主要研究机构。同时作为资助的产出，本研究也着重阐述了DN领域立项相关的杰出研究团队及其代表性成果。 从1986年至2013年NSFC共计资助糖尿病肾病领域项目248项，资助金额总数达9150万（约合$1490万）。随着立项数量和资助金额以每年平均30%和52%的速度递增，DN研究在过去的5年里取得了快速的发展。此外，NSFC资助范围几乎涵盖了DN研究的所有领域，包括病因、病理生理、诊断以及治疗等。随着对DN研究资助力度的不断增加，中国学者在SCI期刊发表的论文数量也有了快速的增加。 总之，在过去的几十年里，NSFC在DN领域的资助比例和资金预算都有了极大的提高，从而极大的促进了该学科持续、稳定的发展。
