Objective To explore the application of digital breast tomosynthesis (DBT) combined with MR wave in the diagnosis of high-risk breast lesions. Methods A total of 100 patients with breast high-risk lesions diagnosed as BI-RADS 4 or above by mammography in our hospital from June 2020 to June 2021 were selected as the research objects. The selected patients were examined by MR spectrum and DBT. The signs of MR spectrum and the photographic characteristics of DBT breast lesions were analyzed. Based on the pathological results, the diagnostic efficacy of MR spectrum, DBT and their combination in the diagnosis of breast high-risk lesions was evaluated. Results The sensitivity, specificity, positive predictive value and negative predictive value of DBT were higher than those of MR spectrum; the missed diagnosis rate and misdiagnosis rate of DBT were lower than those of MR spectrum (P<0.05). There was no significant difference in the coincidence rate of MR spectrum and DBT in the pathological diagnosis of malignant lesions ≥ 2 cm (P>0.05). The coincidence rate of MR spectrum and DBT in the diagnosis of benign and malignant breast lesions<2 cm was higher than that of MR spectrum (P<0.05). Conclusions Selecting DBT in the diagnosis of breast high-risk lesions can make accurate analysis and judgment in the diagnosis of breast high-risk lesions. It has higher application value in the diagnosis of breast high-risk lesions and is worthy of clinical adoption.

目的 观察超声心动图(UCG)+心肌损伤标志物水平检测在急性心肌梗死(AMI)患者诊断中的应用价值。方法 选取2020年6月—2021年9月我院收治的74例AMI患者为观察组,另选取同期65例疑似AMI患者为对照组,2组均进行UCG检测,并对比入院后0~2 h、2~12 h、12~24 h心肌损伤标志物[肌酸激酶同工酶(CK-MB)、氨基末端脑钠肽前体(NT-proBNP)、肌钙蛋白(cTnI)、心脏型脂肪酸结合蛋白(H-FABP)]水平,分析心肌损伤标志物与AMI病情程度的关联性及UCG+心肌损伤标志物水平检测对AMI诊断的应用价值。结果 UCG检查结果显示观察组阳性率86.79%高于对照组9.23%(P＜0.001);对照组入院后各时间段CK-MB、NT-proBNP、cTnI、H-FABP水平差异无统计学意义(P＞0.05)观察组入院后各时间段CK-MB、NT-proBNP、cTnI、H-FABP水平均高于对照组(P＜0.05);Spearman相关分析可知,血清CK-MB、NT-proBNP、cTnI、H-FABP水平与AMI患者病情程度呈正相关(r₁=0.648,r₂=0.692,r₃=0.704,r₄=0.683,P＜0.05);受试者工作特征曲线(ROC)曲线分析显示,UCG+血清CK-MB、NT-proBNP、cTnI、H-FABP联合检测对AMI患者的诊断敏感度(85.14%)、特异度(100.00%)较高(P＜0.05)。结论 UCG+心肌损伤标志物水平检测应用于AMI患者有利于提高诊断敏感度、特异度,诊断价值较高。

目的 探索胸部CT值在胸腔积液鉴别诊断的价值。方法 81例胸腔积液患者纳入本研究,胸腔积液分为渗出液、漏出液、恶性胸腔积液及良性胸腔积液。建立平均CT值的ROC曲线,计算曲线下面积。结果 81例胸腔积液患者中59例为渗出液,22例为漏出液;恶性胸腔积液33例,良性胸腔积液48例。渗出液组平均CT值(16.68±6.76)Hu高于漏出液组(5.50±3.42)Hu(P<0.000 1)。ROC曲线分析结果显示,胸腔积液平均CT值对区分渗出液和漏出液具有较高的准确性(曲线下面积为0.944 5)。当最佳界值为≥9.99 Hu时,其敏感度为88.14%,特异度为90.91%;恶性胸腔积液组平均CT值(15.38±7.29)Hu与良性胸腔积液组平均CT值(12.45±8.03)Hu没有差异(P=0.098 1)。结论 在胸腔积液的鉴别诊断过程中,胸部CT的CT值在鉴别漏出液及渗出液中有一定的价值,但尚不能用于鉴别良性及恶性胸腔积液。

Objective To explore the value of chest CT value in the differential diagnosis of pleural effusion. Methods A total of 81 patients with pleural effusion were included in this study, including exudate, transudate, malignant pleural effusion and benign pleural effusion.The ROC curve of average CT value was established and the area under the curve was calculated. Results Among 81 patients with pleural effusion, 59 cases were exudative, 22 cases were transudative, 33 cases were malignant pleural effusion and 48 cases were benign pleural effusion.The mean CT value of the exudate group, (16.68±6.76) Hu, was significantly higher than (5.50±3.42) Hu of the transudate group (P<0.000 1).ROC curve analysis showed that the mean CT value of pleural effusion had high accuracy in distinguishing exudate from transudate (area under the curve was 0.9445).When the cut-off value for exudative effusion was over 9.99 Hu, the sensitivity and specificity were 88.14% and 90.91%, respectively.The mean CT value of malignant pleural effusion group, (15.38±7.29) Hu, was not significantly different from (12.45±8.03) Hu of benign pleural effusion group (P=0.098 1). Conclusions In the differential diagnosis of pleural effusion, the chest CT value can be used to identify transudate and exudate, but not benign and malignant pleural effusion.

Objective To investigate the value of radial probe endobronchial ultrasound (RP-EBUS)guided multi-dimensional combined examination in the diagnosis of peripheral lung cancer. Methods A retrospective analysis of 74 patients with peripheral lung cancer which were diagnosed in Foshan Second People's Hospital from September 2019 to December 2021 was carried out. RP-EBUS guided biopsy, brushing biopsy, bronchus alveolar lavage cytology and DNA methylation detection results were analyzed to obtain the positive diagnosis rate and influencing factors. Results The positive rates of RP-EBUS guided biopsy, brushing biopsy, bronchus alveolar lavage cytology and methylation for peripheral lung cancer were 52.7%, 47.3%, 45.9% and 51.4%, respectively. The positive rate of RP-EBUS guided multi-dimensional combined detection was 71.6%, which was significantly higher than single detection (P<0.05). The positive rate of RP-EBUS multi-dimensional combined examination in lesions diameter ≥30 mm was higher than that of lesion diameter ＜30 mm (82.9% vs 57.6%, P<0.05). The positive rate of RP-EBUS guided multi-dimensional combined group in the upper lobe, middle lobe/lingual lobe, and lower lobe of the lung were 69.7%, 66.7% and 76.9%, respectively, with no significant difference (P>0.05). The positive rate of ultrasound detected lesion in combined group was higher than that of undetected lesions (76.9% vs 33.3%, P<0.05). The ultrasound images of solid center lesions had higher positive rates than that of non solid center lesions (86.0% vs 59.1%, P<0.05). Conclusions RP-EBUS guided multi-dimensional combined examination has a higher positive rate for diagnosis of peripheral lung cancer. The positive rate of diagnosis are related to the size of the lesion, whether the lesion is detected by ultrasound and the characteristics of the ultrasound image of the lesion, but not related to the location of the lesion.
