RESUMO
Objective:To study the safety factors of Fuyanyu mixture. Methods: The contents of antiseptic and residual ethanol were determined by HPLC and GC, respectively, and those of heavy metals and harmful elements were detected by ICP-MS. Results:The contents of benzoic acid in 6 batches of samples were less than 0. 3%. In two thirds of samples, ethanol residue was more than 0. 5%. The total mercury exceeded 15μg/day in one of the samples, and the contents of Pb, Ge, Gr, As, Ni and Cu met the limits described in USP<232> in all of the last samples. Conclusion: The methods are accurate and reliable. It is urgent to improve the preparation process so as to reduce the residual amount of ethanol according to the detection results. It is recommended to increase the testing items that affect the safety of the preparation so as to control the preparation quality strictly.

RESUMO
During the reform of higher education, Chinese researchers began to do more and more research on generaleducation. But there are still some arguments that need clarifying on the issues of general education among Chineseresearchers, In this article, the author analyzes and points out the different opinions on general education in Chinathrough the following aspects: the different translation of general education from English into Chinese; the definition ofgeneral education; the relationship between general education and humanities education, specialized education, andquality-oriented education; the way of general education practice; and the time limitation of general education in under-graduate education.[
