          Results Among the 121 patients diagnosed with acute brucellosis, 92 were male (76.03%) and 29 were female (23.97%). The ratio of male to female was 3.14∶1.00, which the male incidence was higher. The average age of the selected cases was (44.52±11.78) years old, and the onset time was mainly from April to June. The main occupations of the selected patients were farmers, followed by cattle and sheep farmers. There were 79 cases (65.29%) of contact with cattle and sheep. Among the 121 patients who were enrolled, 105 (86.78%) had fever, the shortest fever time was 7 days, and the longest fever time was intermittent fever for more than 3 months. The fever was obvious in the afternoon and night. The low- fever body temperature was 37.3 -<38.0 ℃ in 24 cases (19.83%), the moderate-fever temperature was 38.0 -<39.0 ℃ in 52 cases (42.98%), and the body temperature ≥39 ℃ in 29 cases (23.97%), and there were 16 cases with no fever (13.22%). Some patients had symptoms such as chills, fatigue, muscle and joint pain, and sweating. Among the selected patients, WBC was normal in 73 cases (60.33%), WBC increased in 30 cases (24.79%), WBC decreased in 18 cases (14.88%), hsPCR increased in 82 cases (67.77%), PCT increased in 63 cases (52.07%), ALT increased in 51 cases (42.15%), AST increased in 47 cases (38.84%), AKP increased in 38 cases (31.04%), γ - GT increased in 45 cases (37.19%), Hb decreased in 13 cases (10.74%), PLT decreased in 16 cases (13.22%), ESR increased in 83 cases (68.60%). The main complications of brucellosis were osteoarthritis in 41 cases (33.88%), orchitis or epididymitis in 6 cases (4.96%), central nervous system in 5 cases (4.13%), endocarditis or pericarditis in 3 cases (2.48%). 121 patients were cured after active medical treatment, and there was no recurrence during follow-up.
