Objective To explore the distribution of pathogens in lower respiratory tract infection, and to explore the drug resistance, and summarize the clinical experience.MethodsFrom February 2014 to August 2016 in Changxing county people's hospital, the specimens of the patients with lower respiratory tract infection were analyzed.Distribution of pathogenic bacteria was analyzed and its drug resistance was summarized.ResultsA total of 100 strains of bacteria were isolated, including 27(27%) strains of fungi, 26(26%) strains of gram positive bacteria, 47(47%) strains of gram negative bacteria.The proportion of gram negative bacteria was significantly higher than that of gram positive bacteria and fungi, and the difference was statistically significant (P<0.05).Different pathogenic bacteria have different drug resistance to commonly used antibiotics.The resistance of Candida albicans to fluconazole was 100.0%, the resistance of Staphylococcus aureus to compound sulfamethoxazole was 90% and to gentamicin was 100.0%, the resistance of Escherichia coli to levofloxacin was 100.0%.ConclusionGram negative bacteria accounted for the highest proportion in pathogen of lower respiratory tract infection.Different pathogenic bacteria have different resistance to different antibiotics in clinical, and monitoring and rational use of drugs should be strengthened in order to improve the efficacy and reduce drug resistance.

Objective By quantitative tissue velocity i maging(QTVI),to observe longitudinal wall motion characteristics during isovolumic contraction, ejection, isovolumic relaxation, early relaxation, atrial systole phases in regional myocardium of myocardial infarction patients with three diseased blood vessels, and to assess postsystolic shortening in isovolumic relaxation phase and its clinical meanings. Methods Left ventricular regional myocardium of 30 myocardial infarction patients (MI group) and 30 non-cardiac disease subjects (control group) was assessed by QTVI. After dynamic images were collected and information was analyzed off-line, left ventricular myocardial velocity and time velocity integral profiles were acquired along long axis asynchronously in basal and middle segments of different walls, peak velocities (V IC , V S, V IR , V E, V A) during different phases and maximum time velocity integral (TVI max )in regional myocardium was measured. Results Peak velocities(V IC , V S, V IR , V E, V A) in different segments of left ventricular regional myocardium in MI group were lower than those of control group, especially more obviously in infarcted segments. Peak velocity amplitude in ejection declined, but it had positive velocity spike; abnormal positive velocity in isovolumic relaxation phase suggested postsystolic shortening. What's more, time velocity integrals in some segments of MI group had two wave crests, reached maximum in isovolumic relaxation phase, but were still lower than that of control group. Conclusions Systolic and diastolic function in MI patients with three diseased blood vessels are apparently impaired; abnormal movement in isovolumic relaxation phase suggests existence of postsystolic shortening and abnormal wall motion in regional myocardium.V IR is a marker of abnormal regional wall motion and ischemic myocardium.
