Study on genetic and cultural diversity of Hans in China

1997年度我们进行了以下研究：（1）岩田先生于8 - 9月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月访问了北京和西安，并在西安郊区采集了血样。三名中国合作者（Jin，Yuan和Zhan）以及另外两名研究人员（Wan，Kitano和Iwamoto）也加入了这项研究。(3)斋藤和汤浅于11月访问了北京和昌沙，并在昌沙郊区采集了血液样本。(4)11月，Horai和Tokunaga访问了北京和昆明，并在昆明郊区采集了血液样本。(5)1998年度，我们与日本东京大学和国立遗传学研究所的研究人员进行了以下研究：（1）齐藤、上田和万研究员访问了北京、安延和新安，进行了从人类遗骸中提取古DNA的初步研究。金峰也参加了此次学习。(2)两名中国合作者（Jin和Cao）于10月访问了日本，并在国际日本研究中心储存的样本中研究了红细胞酶的遗传多态性。(3)斋藤、大本、堀井、德永、汤浅和野田研究员于1999年1月访问了中国，并在广州、福州和杭州附近采集了血样。Jin和Cao也参与了这项研究。(4)上田访问北京的古代DNA研究。

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.
