灵敏度分析

The sensitivity and specificity of far-infrared thermography in the diagnosis of lumbar disc herniation were evaluated. Compared with the normal, the thermogram of twenty-three cases on low back with LDH changed. They can be divided into four thermal patterns that is shuttle-liking (8 cases), discontinued in the middle line (6 cases), large regional (5 cases) and nonregular (4 cases) pattern. The temperature of abnormal sides is lower than the counterpart in most cases (nineteen of twenty-three). The thermography diagnosed LDH with sensitivity 90.48% and specificity 66.68%.

结果 F-IRT显示：23例LDH患者腰骶部热形态改变为四种形式：梭形，热区向一侧偏歪或呈角状突起（8例）；夸中线热区不连贯（6例）；骶髂骨上缘呈大片高温热区（5例）；不规则形态（4例），患侧下肢较相对应的对侧胶体的温度，至少有一个患侧部位出现温度下降的有19例(82.61%)，综合CT与F-IRT结果分析：F-IRT诊断腰椎间盘侧后突的灵敏度为90.48%，特异度为66.68%。

Methods: We collected 121 of clinical isolates of Enterobacter, including 87 isolates Enterobacter cloacae, 34 isolates Enterobacter aerogenes, all of the isolates were detected by cefoxitin three-dimension test, drug resistance phenotypes estimation, cloxacillin disc synergy test and cloxacillin-potentiated disc diffusion test respectively to find high-level AmpC β-lactamase isolates, drug resistance phenotypes estimation were also used to detected high induction producing AmpC β-lactamases isolates, meanwhile, we took three-dimension test as standard method, and compared to other methods, then calculated the coincidence rates, sensitivities and specificities of them.
