Objective To summarize the distribution of departments,conditions of diagnosis and treatment of the syphilis patients in the general hospitals,and thus to improve the level of diagnosis and treatment.Methods A retrospective analysis of epidemiology and clinical data of 282 cases with syphilis in recent 5 years were conducted. Results The ratio of male to female was about 1:1.9.Female showed a high incidence in the 21 -50 years old,aver-age (41.68 ±0.96)years old,but for male in the 41 -70 years old,average (53.25 ±1.59)years old.The cases combined with other infectious diseases accounted to 22.0 % (62/282).The cases from the department of obstetrics and gynecology were the most (106 cases),followed by surgery (86 cases)and internal medicine (49 cases).Only 23 cases showed the clinical manifestations of syphilis in the 79 cases,which must be treated.The test rate of TRUST was only 39.0% (110/282).Furthermore,it was very low for the rate of treatment and standard treatment. Conclusion Syphilis is the most in department of obstetrics and gynecology in general hospital,and it is also com-mon in the surgery and internal medicine.The most prominent problems are that the non-special doctors had weak awareness for definite diagnosis of syphilis,and the low rate of treatment and standard treatment.
