On the similarities and differences between ZHU Danxi's and ZHANG Congzheng's methods of eliminating pathogenic factors from "ZHU Danxi's case of dysentery".

ZHU Danxi and ZHANG Congzheng were representative doctors from the Jin-Yuan dynasties. They belonged to the Hejian School, but they had notable differences in the order of reinforcing healthy qi and eliminating pathogenic factors. In the classic medical case " ZHU Danxi's treatment of dysentery", ZHU Danxi adopted the treatment method of " First treating its deficiency and then treating its excess" for patients with excess pathogen, which was contrary to ZHANG Congzheng's claim that " Treatment should first eliminate the pathogenic factor". By systematically analyzing the similarities and differences between the two methods of eliminating pathogenic factors, it was found that both used the three method of sweat promotion, emetic therapy, and purgation, and both paid attention to avoiding the harmful effects of eliminating pathogenic factors on qi of spleen and stomach. However, in the order of reinforcement and elimination, ZHU Danxi emphasized that " The pathogenic factor should be carefully eliminated, and healthy qi should be protected", while ZHANG Congzheng thought that " The healthy qi should not be tonified before the pathogen is eliminated". In the order of treating the spleen and the stomach, ZHU Danxi often supplemented the stomach qi and then eliminated pathogenic factors in patients with spleen-stomach weakness, while ZHANG Congzheng thought that the pathogenic factor should be eliminated first and then stomach qi should be restored. Taking classic medical records as an example, this paper discusses the reasons for the different method between the two doctors from the viewpoints of their ideological origin, the succession of teaching from a master to his disciples, social background, and geographical environment, so as to provide a basis for further exploring the method of learning about medical records and the perspective of understanding medical records.
