ABSTRACT
Objective To investigate antimicrobial resistance and change trends ofUreaplasma urealyticum (Uu) from reproductive system of female patients at a traditional Chinese medicine hospital in three consecutive years. Methods Antimicrobial resistance of Uu isolated from gynaecology leucorrhea and cervical secretion specimens of patients of dermatology & sexually transmitted diseases department and gynaecology department from January 2011 to December 2013 were analyzed retrospectively.Results A total of 327 Uu strains were isolated,except resistance rates of Uu to doxycycline(5.23%-6.12%)and josamycin(0-1 .96%)remained at a relatively low level in three consecutive years,resistance rate to the other antimicrobials showed an upward trend year by year,but the difference was not significant (P >0.05).The resistance of Uu to ofloxacin,clarithromycin and sparfloxacin were relatively high(42.11 %-61 .40%),to josamycin,doxycycline and minocycline were lower(0-13.07%),and multidrug re-sistance was serious.Conclusion Antimicrobial resistanc of Uu isolated from reproductive system of female patients in this hospital is high.It is necessary to realize the status and change trends of antimicrobial resistance of Uu for the treatment of disease and control of the emergence of multidrug resistance pathogens.
ABSTRACT
Objective To investigate the levels and clinical significance of the ratio of apolipoprotein B(apoB)and apolipoprotein A1(apoA1)in the patients with cerebral infarction,and to determine the critical value of apoB/apoA1 inthe patients with ischemic cerebral infarction.Methods 126 inpatients with cerebal infraction diagnosed by MRI enhancement scanning of the head in our hos-pital.From November 1,2012 to May 15,2013 were selected.Among them,51 cases were common carotid artery intima-media thickening(carotid artery intima-media >0.9 mm)and 75 cases were carotid artery intima-media non-thickening by the color ultra-sonic examination;81 cases had atherosclerosis plaque and 45 cases had no atherosclerosis plaque.57 individuals with healthy physi-cal examination were selected as the control group.The fasting serum samples were collected from all the research subjects.The in-dexes of TG,CHOL,HDL-C,LDL-C,apoB,apoA,etc.were detected.Then the independent t-test was adopted to analyze and com-pare the ratio of apoB/apoA1 and others related indictors(including TG,AIP,apoB,apoA1,etc.)in the various groups.The ROC curves were made,the area under the curve was read and the specificity and sensitivity of apoB/apoA1 for diagnosing ischemic cere-bral infarction were calculated.Results (1)AIP and the ratio of apoB/apoA1 in the ischemic cerebral infarction patients were high-er than those in the control group,the rise rate of apoB/apoA1 ratio in the ischemic cerebral infarction patients was 5.43 times of that in the control group,especially the patients with carotid atherosclerosis or carotid artery intima-media thickenning were more significant,while TG and apoB had no obvious changes.(2)the ratio of apoB/apoA1 had no obvious difference between the carotid artery intima-media thickening group and the carotid artery intima-media non-thickening group,while which in the atherosclerotic plaques group was significantly increased compared with no carotid atherosclerosis group and 1.6 times of that in the normal control group.So it could be considered that the apoB/apoA1 ratio was a specific indicator for atherosclerosis.(3)In the diagnosis of ische-mic cerebral infarction,the area under the apoB/apoA1ROC curve was 0.86.its specificity and sensitivity were higher than other in-dexes.Conclusion The apoB/apoA1 ratio is the most specific and sensitive index in the patients with ischemic cerebral infarction and has good correlation with ischemic cerebral infarction,especially in the presence of carotid atherosclerosis plaque it is more sen-sitive,and is a good index of laboratory diagnosis of ischemic cerebral infarction.
