ABSTRACT
Objective To analyze the distribution of reproductive tract infection(RTI)pathogens and the drug sensitivity of My-coplasma in infertile women.Methods Experimental examinations of the pathogens related to RTI were performed in 260 cases of infertile women(test group)and compared with 260 cases of pregnant women(control group).Results In test group,the positive rate of RTI pathogens was 61.2%.The top 3 pathogens were Mycoplasma (47.7%),Candida (30.0%)and bacterial vaginosis (BV)pathogens(16.7%).There were significant differences of BV pathogens,Mycoplasma,and pH value between test group and control group(P 0.05).The drug sensitivity rates of Ureaplasma urealyticum to doxycycline and minocin were above 90%,and which to quinolone was less than 40%.Conclusion BV pathogens and Mycoplasma infection is one of the important factors which could affect women infertility.It is necessary to strengthen the monitoring and rational use of antimicrobial agents.
ABSTRACT
Objective To evaluate the clinical significance of detection of serum procalcitonin(PCT),high sensitivity-C-reactive protein(hs-CRP)and leukocyte in acute exacerbation of chronic obstructive pulmonary disease(AECOPD)patients.Methods 45 patients with AECOPD and 50 patients(AECOPD group)with chronic obstructive pulmonary disease(COPD)in slationary phase (COPD group)were selected,and their serum levels of PCT,hs-CRP and leukocyte were tested.Results Before treatment,the con-centrations of PCT and hs-CRP were (3.32±1.81)ng/mL and (22.36±5.03)mg/L in AECOPD group respectively.They were significantly higher than those in COPD group with statistical differences(P<0.01).The positive predictive value of PCT and hs-CRP was 68.9% and 60.0% in AECOPD group respectively,which were significantly higher than those in COPD group(P<0.01).After antibiotic treatment,the leukocyte,PCT,and hs-CRP levels in AECOPD group were significantly lower than those be-fore treatment(P< 0.01).Conclusion In AECOPD patients,PCT and hs-CRP are good diagnostic indexes.
ABSTRACT
Objective To observe the clinical characteristics, risk factors, and sensitivity to antibiotics of nosocomial infections caused by acinetobacter baumannii. Methods Data were retrospectively collected from all isolated 37 strains acinetobacter. The clinical features, results of suptum culture and test of drug sensitivity were reviewed. Results The 37 acinetobacter baumannii strains mainly distributed in intensive care unit (ICU), most of them had the risk factors of receiving invasive treatment, mechanical ventilation, ect. The antibiotics imipenem, amikacin, pipercillin/tazobactam showed good efficacy for patients with acinetobacter infection, but other antibiotics had highly drug resistant rate. 5 were dead. The mortality of nosocomial infections caused by multi-drug resistant acinetobacter was 41.7%, which was much higher than the non-multi-drug resistant's (2 dead, the mortality was 8%). Conclusion Acinetobacter is one of the most important multi-drug resistant pathogen in nosocomial infections. Antimicrobial agents should be chosen according to antimicrobial susceptibility teat results. Patients who have the risk factors of nosocomial infections caused by acinetobacter should have suptum culture and antibiotic susceptibility studies as soon as possible.
ABSTRACT
Objective To investigate infection statue and antibiotic susceptibility of Mycoplasma urealyticum and Mycoplasma hominis in the genitourinary tract in our area, so as to instruct the rational use of antibiotics. Methods Genitourinary secretions were collected with swabs. They were cultured with the diagnostic kit of Mycoplasma (Biomerieux Company) to detect M. urealyticum and M. hominis. Meanwhile the susceptibility of Mycoplasma against 9 antimicrobial agents was tested with the same kit. According to the manual of the kit,the results were read. The data were statistically analyzed. Results A total of 2 410 samples were collected, and the positive rate was 58. 1%. Among 1410 positive cases of Mycoplasma, 901 cases were M. urealyticum (37.4%), 85 were M. hominis (3.5%), and 415 were M. urealyticum combined with M. hominis (17.2%).The susceptibility rate of M. urealyticum to josamycin, pristinamycin, ciprofloxacin was 98. 8%, 98. 8% and 6. 4% respectively, while the susceptibility rate of M. urealyticum combined with M. horninis was 86.9%,86. 8% and 2.6% respectively. Conclusion M. urealyticum is the major cause of Mycoplasma infection in genitourinary system. Josamycin and pfistinamycin are more effective than other antimicrobial agents to treat Mycoplasma irffection. Ciprofloxacin is more resistant than other antimicrobial agents. Sensitive antibiotics should be selected based on the results of bacterial culture and drug sensitivity tests so as to raise the clinical curative effects.
