Methods A retrospectively analysis was conducted on 209 strains of KPN isolated from the clinical specimens in the People's Hospital of Puyang City from January 2020 to March 2020. Results A total of 209 strains of KPN were isolated from clinical specimens, accounting for 68.30% of enterobacteriaceae bacteria; the sources of specimen were mainly from sputum, blood and urine, accounting for 75.11%, 9.09% and 5.74% respectively; the departments with more isolated strains were ICU department, neurosurgery first department, EICU department, and thoracic surgery department, accounting for 47.37%, 17.7%, 3.35% and 3.35% respectively. Besides, the detection rate of extended spectrum β-lactamase(ESBLs) strains was 11.48%,and the detection rate of carbapenems-resistant klebsiella pneumoniae (CRKP) strains was 58.37%. The results showed that the drug resistance of KPN from different sources was with a significantly difference, and the drug resistance rate of KPN in comprehensive ICU was significantly higher than that of other departments. Conclusion The resistance of KPN isolated from the People's Hospital of Puyang City to common antibiotics is not optimistic. In particularly, the drug resistance of KPN isolated strains from the comprehensive ICU is more serious. Hence, the monitoring of KPN resistance should be strengthened and the effective prevention and control measures of hospital infection should be adopted. Furthermore, antibacterial drugs should be used rationally to reduce the generation of drug-resistant bacteria.
目的 通过建立特征参数曲线模型分析在不同CT扫描条件下对肺结节鉴别诊断的量化意义。方法 回顾性分析2018年9月—2019年10月我院收治的肺结节患者的CT胸部平扫图像为研究对象,纳入标准为结节直径≥3 mm,无其他病史。在筛选出的96例样本中,符合条件的样本68例(男性39例,女性29例),按扫描剂量的不同将研究对象分为低剂量观察组(管电压120 kV,管电流20 mA)和常规剂量组(管电压120 kV,管电流150 mA),每组各34例;通过测量并计算扫描长度、有效剂量、样本体型、信噪比相关参数,观察不同管电流与有效辐射剂量之间的相关性以及图像质量;运用PACS人工智能软件以及人工综合提取肺结节特征信息(直径、体积、密度纹理、边缘细节、内部结构)并记录数据,进而通过公式计算出肺结节质量;应用U检验分析比较不同管电流下各参数的组间差异,经过单元逻辑对确定的重要参数体积与质量纳入多元逻辑分析,建立特征参数曲线模型并测量曲线下面积及勾画ROC;使用卡方分析评价不同管电流下建立特征参数曲线模型对肺结节定量诊断分析的差异并同时比较不同管电流下的图像质量。结果 研究中发现,样本接受的有效辐射剂量在管电压一定的条件下,随管电流的增加而线性增加;样本肥胖患者(BMI≥23.9)的CT图像在使用低剂量扫描中呈现出明显噪声,影响组织间观察,而BMI标准(18.5≤BMI≤23.9)的样本的CT图像中,肺结节的信噪比与管电流变化未出现明显趋势阈值,差异无统计学意义(P＜0.05);通过特征参数曲线模型显示,肺结节的体积与质量均质性曲线显示出其变化趋势与管电流变化成相关性,且稳定性和一致性较好,故此二要素为模型主要分析成分,观察组ROC曲线显示其曲线下面积为0.826高于常规组ROC曲线显示其曲线下面积为0.747。结论 与常规剂量相比,低剂量CT扫描模式下建立特征参数曲线模型对肺结节鉴别诊断更有可量化意义。
Objective The quantitative significance of differential diagnosis of pulmonary nodules under different CT scanning conditions was analyzed by establishing characteristic parameter curve model. Methods CT plain chest scan images of patients with pulmonary nodules treated in our hospital from September 2018 to October 2019 were analyzed retrospectively. The inclusion criteria were nodule diameter ≥3 mm and no other medical history. Of the 96 selected samples, 68 met the criteria (39 males and 29 females).According to the different scanning dose, the subjects were divided into low dose observation group (tube voltage 120 kV, tube current 20 mA) and conventional dose group (tube voltage 120 kV, tube current 150 mA).There were 34 cases in each group, and the correlation between different tube current and effective radiation dose and image quality were observed by measuring and calculating the relevant parameters of scanning length, effective dose, sample shape and signal-to-noise ratio. PACS artificial intelligence software and artificial synthesis were used to extract the characteristic information (diameter, volume, density texture, edge details, internal structure) of pulmonary nodules and record the data. Furthermore, the mass of pulmonary nodules was calculated by formula, the differences of parameters under different tube currents were compared by U test, the volume and mass of important parameters determined by unit logic were incorporated into multivariate logic analysis. The curve model of characteristic parameters was established, the area under the curve was measured and ROC was sketched. Chi-square analysis was used to evaluate the difference of characteristic parameter curve model for quantitative diagnosis of pulmonary nodules under different tube currents, and to compare the image quality under different tube currents at the same time. Results In the study, it is found that the effective radiation dose received by the sample increases linearly with the increase of tube current under the condition of constant tube voltage. The CT images of obese patients (BMI≥23.9) showed obvious noise when using low dose scan, which affected the inter-tissue observation. However, in the CT images of the samples with BMI standard (18.5 ≤ BMI ≤ 23.9), there was no obvious trend threshold between the signal-to-noise ratio and tube current of pulmonary nodules, and the difference was not statistically significant (P<0.05).The characteristic parameter curve model showed that the volume and mass homogeneity curve of pulmonary nodules showed the change trend was correlated with the change of tube current, and the stability and consistency were good, so the two elements were the main analytical components of the model. The ROC curve of the observation group showed that the area under the curve was 0.826, which was higher than that of the conventional group, the area under the curve of the ROC curve was 0.747. Conclusion Compared with conventional dose, the establishment of characteristic parameter curve model under low dose CT scan mode is more quantifiable for differential diagnosis of pulmonary nodules.
