Objective To understand the empiric antimicrobial use in patients with pyelonephritis in a hospital,and pro-vide reference for clinical rational antimicrobial use.Methods Data of 620 patients with pyelonephritis admitted to the nephrology department of a hospital between January 2011 and September 2014 were collected,application of antimicrobial agents,coincidence between empiric antimicrobial use and antimicrobial susceptibility testing results in patients with different diseases and different ages were analyzed.Results Before antimicrobial susceptibility testing results were reported,620 pa-tients use 625 times of antimicrobial agents,5 of whom used two kinds of antimicrobial agents at the same time,8 varieties in 15 types of antimicrobial agents were involved,the most frequently used antimicrobial agents were third generation ceph-alosporins,cephamycins,and fluoroquinolones.The overall,partial,and non-coincidence rate between antimicrobial use and antimicrobial susceptibility testing results were 64.32%(n=402),8.32%(n=52),and 27.36%(n=171)respective-ly.The overall coincidence rate in patients with acute pyelonephritis was higher than those with chronic pyelonephritis (77.61% [n=357]vs 58.79%[n=97],P <0.05).The overall coincidence rate in patients <50 years old and ≥50 years old were 68.12%(156/229)and 75.25%(298/396)respectively,there was no significant different between two groups (χ2 =2.93,P =0.09).Conclusion The non-coincidence rate between empiric antimicrobial use and antimicrobial suscepti-bility testing results is high,measures needs to be taken to improve the empiric antimicrobials use.

Objective To evaluate the clinical effect and complications of total hip replacement (THR) in novel femoral neck fracture,old femoral neck fracture, aseptic necrosis of femoral head and coxa degenerative osteoarthropathy. To provide instructions to surgical indications and treatment effects analysis.Methods One hundrde and four patients were divided into 4 groups by disease type: novel femoral neck fracture group (n = 32 ), old femoral neck fracture group (n = 22) ,aseptic necrosis of femoral head group (n =34) and coxa degenerative osteoarthropathy group (n = 16). These patients were followed-up for 12 - 144 months after THR, their Harris standard score and complications data, before and after operation, were analyzed retrospectively. Results After operation, the Harris standard scores were 92. 6 ± 5.8,90. 1 ± 5. 2,86. 3 ± 4. 6,81.9 ±4. 1 in novel femoral neck fracture,old femoral neck fracture,aseptic necrosis of femoral head and coxa degenerative osteoarthropathy groups respectively, which were significantly higher than the scores before operation (25.6±1.8,36.7±2.6,52.9±4.3,42. 1 ±3.8,Ps <0.05). Conclusion THR has good effects in the four types of diseases. Short length of stay and high healing rate are marked characteristics of THR. More attention shoud be paid to the complications of THR.
