Methods: A randomized, single blind controlled clinical design was used to accomplish the series clinical trials included 123 cases. The troop of gatifloxation injection with sodium chloride included 20 cases in gatifloxation group and 23 cases in ciprofloxation group; The troop of gatifloxation injection with glucose included 21 cases in gatifloxation group and 19 cases in levofloxacin group; The troop of gatifloxation pivoxil included 19 cases in gatifloxation group and 21 cases in ciprofloxation group. The antibacterial activity of clinical isolates were detected by scrips which contain gatifloxation(5ug/L), levofloxacin (5ug/L), ciprofloxation (5ug/L), spafloxation(5ug/L), cefotaxime(30ug/L), penicillin(10U/L) respectively. The MICs of sixkinds of antibiotics were detected by 2-fold agar dilution method. Result: The common data of patients in the two groups of 3 troops were similiar.
