Study on genetic and cultural diversity of Hans in China

我们在1997财政年度进行了以下研究：(1)岩田在8 - 9月期间对中国中部地区的方言边界进行了研究。(2)斋藤和上田于9月访问北京和西安，在西安郊区采集血样。三位中国合作者（Jin， Yuan和Zhan）以及另外两位研究人员（Wan， Kitano和Iwamoto）也加入了该研究。(3)齐藤和汤浅于11月访问北京和长沙，并在长沙郊区采集血样。(4) Horai和Tokunaga于11月访问了北京和昆明，并在昆明郊区采集了血液样本。(5) 3名中国合作者访问日本，与东京大学、国立遗传研究所的日本成员进行了合作研究。在1998财政年度，我们进行了以下研究：(1)saiitou， Ueda和研究员Wan访问了北京，安安和新安，并从人类遗骸中提取古代DNA进行了初步研究。金峰也参加了这次研究。(2)中国合作者Jin和Cao于10月访问日本，对日本国际研究中心保存的红细胞酶基因多态性进行了研究。(3) saiitou、Omoto、Horai、Tokunaga、Yuasa和Noda研究员于1999年1月访问中国，在广州、福州和杭州附近采集了血液样本。Jin和Cao也参与了这项研究。(4)上田为古代DNA研究访问了北京。

We conducted the following studies in the fiscal year 1997 : (1) Iwata did a study on dialect border of Central part of China during August-September. (2) Saitou and Ueda visited Beijing and Xian in September, and collected blood samples in the surburb of Xian. Three Chinese collaborators (Jin, Yuan, and Zhan) as well as two other researchers (Wan, Kitano, and Iwamoto) also joined that study. (3) Saitou and Yuasa visited Beijing and Chansha in November, and collected blood samples in the surburb of Chansha. (4) Horai and Tokunaga visited Beijing and Kunmin in November, and collected blood samples in the surburb of Kunmin. (5) Three Chinese collaborators visited Japan and did a collaborative studies with Japanese members at University of Tokyo and National Institute of Genetics.In the fiscal year 1998, we conducted the following studies : (1) Saitou, Ueda, and researcher Wan visited Beijing, Anyan, and Xinan, and conducted a preliminary study to extact ancient DNA from human remains. Jin Feng also attended this study. (2) Two Chinese collaborators (Jin and Cao) visited Japan in October, and studied genetic polymorphism of red blood cell enzymes on samples stored at International Center for Japanese Studies. (3) Saitou, Omoto, Horai, Tokunaga, Yuasa, and researcher Noda visited China in January 1999, and collected blood samples near Guanzhou, Fuzhou, and Hanzhou. Jin and Cao also were involved in that study. (4) Ueda visited Beijing on the ancient DNA study.
