Minor comments  
 
Please think about the significant figures of the data. So many significant figures of the data of 
the tables and m anuscript make the paper hard to read. For example, 19.832±14.381 days are too 
many, and 19±21 days will be enough. The same for other data such as 97.546 ％. 
 
Page 12, l4 lines from the bottom: "15.317±9.243 and 18.519±11.381" should be "15±9 days and 
18±11 days".  
 
English should be corrected by the publisher prior to publication.
