ABSTRACT
OBJECTIVE To investigate the drug resistance of lower respiratory infection by Acinetobacter baumannii in ICU,in order to provide reference for clinical anti-infection treatment.METHODS We collected 128 A.baumannii strains through bacterial culture of lower respiratory tract secretions from patients after intubation or tracheal incision during Dec 2006 to Dec 2008,and analyzed the results of the drug resistance.RESULTS A.baumannii had high resistance rate to the most antibacterials,The antibiotics with the highest drug resistance rate were cefalotin(99.22%),cefoxitin(96.09%) and cefuroxime(94.53%),while Sulperazon has the lowest drug resistance rate(6.25%).CONCLUSIONS A.baumannii is one of the most important conditional pathogenic bacterium in ICU,which has high resistance rate to most antibacterials,so clinical physicians must pay more attentions to it.
ABSTRACT
Objective To investigate the female mycoplasma urogenital infections and drug-resistance.Methods Liqid medium was used to indentify mycoplasmas and detect the susceptibility in vitro of thirteen antimicrobial agents.Results The total rate of mycoplasma infection was 44.0%, including Uu 37.1%, Mh 0.9%, Uu and Mh compound infection was 6.0%. The susceptible rate of more than 80% were jossamycin (90.8%), clarithromycin (88.5%),azithromycin (84.8%) and minocycline (81.2%). The susceptibilities in vitro of all sorts of antibiotic decreased significantly for Uu and Mh compound infections.Conclusion Mycoplasmas produce particular resistance to antibiotics.Jossamycin,clarithromycin,azithromycin and minocycline can be the drugs of first choice.
ABSTRACT
The arterial supply of the human tibia in 50 specimens, ranging in age from 4 to 87 years, has been studied by the arterial perfusion method. The tibia is supplied principally by branches of the anterior and posterior tibial arteries and the peroneal artery, with additional contributions from the inferior genicular arteries, the middle genicular artery and from the infrapatellar branch of the descending genicular artery. There is a continuous arterial anastomosis in the periosteal network on the non-articular surface of the tibia. The segmental periosteal ring arteries dividing into ascending and descending branches, connect with the branches from above and below to form the longitudinal anastomoses along the anterior, medial and the lower one-third of lateral tibial borders. The epiphyseal-metaphyseal regions are copiously supplied by vessels entering from the periphery and by the nutrient artery. With the fusion of the epiphyseal plate, a free anastomosis is established between the epiphyseal and metaphyseal nutrient vessels. The whole of the marrow and the inner two-thirds or three-quarters of its cortex are supplied by the nutrient artery. The outer third or fourth of the cortex is supplied by the periosteal vessels. Because the cortical longitudinal and transverse capillary systems are profusely anastomosed with each other and with the periosteal and endosteal circulatory networks, the blood can flow in either direction, depending on physiological conditions.The clinical significance of the arterial distribution to the tibia is briefly discussed.
