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 explore the application of transesophageal echocardiography (TEE) probe insertion under video laryngoscopy in acute severe patients. Methods Sixty acute severe patients, ASA grade II-IV, underwent non-cardiac surgery under general anesthesia were divided into two groups (A and B) evenly by random number method.TEE probe was blindly inserted into the group A patients, and in group B, a video laryngoscope was used to assist the insertion.The first insertion success rate, the time required for insertion, the changes of hemodynamics during insertion, and the adverse reactions incidence during insertion of the two groups were compared. Results The first insertion success rate of the group B (82.8%) was significantly higher than that of the group A (58.6%), the difference was statistically significant (P<0.05). The time required for the first successful insertion of the group B was significantly longer than that of the group A, (24.6±3.1) s vs (15.5±3.0) s, and the difference was statistically significant (P<0.05). The total time required to insert the probe was not significantly different between the two groups (P> 0.05). Throat injury in the group B was significantly less than that in the group A (3.4% vs 27.6%), the difference was statistically significant (P<0.05). The hemodynamics (MAP and HR) of the two groups during insertion were not significantly different (P>0.05). Conclusions Video laryngoscope can improve the conditions of transesophageal ultrasound probe insertion, increase the success rate of insertion, and reduce the corresponding complications.It can be safely used for TEE probe insertion in acute severe patients in an emergency.

目的 探讨肺部超声(LUS)在高龄(≥75 岁)感染新型冠状病毒肺炎(COVID-19)患者中的应用及后续对病程的监测及诊断价值。方法 回顾性分析2022年11月1日—2023年1月15日本院内科收治的25例COVID-19高龄患者进行病例归纳总结,除临床资料外,动态监测肺部超声检查情况,并与肺CT结果对比,观察检查结果,以及对病程转归的预判及影响。结果 LUS检查提示患者出现不同程度肺间质损伤,包括离散型B线(间质渗出)或融合型B线(渗入肺泡)以及肺实变(肺泡萎陷)。随着病情好转,LUS可见肺实变范围缩小,B线逐步稀疏到消散,A 线出现。结论 LUS与同期胸部CT结果一致性良好。LUS检查安全简便,重复性好,可实时动态监测,即可作为初筛手段,亦可运用于特殊人群,协助临床治疗决策。

Objective To explore the application and follow-up monitoring and diagnostic value of lung ultrasound (LUS) in elderly patients(≥75y) with novel coronavirus pneumonia (COVID-19). Methods Data of 25 COVID-19 elderly patients admitted to the Department of Internal Medicine from November 1, 2022 to January 15, 2023 were retrospectively analyzed and summarized. In addition to clinical data, dynamic monitoring of LUS was performed, and the results were compared with lung CT results. The examination results, as well as the prediction and impact on the course of disease were observed. Results LUS imaging indicated that patients had different degrees of interstitial lung injury, including discrete type B line (interstitial exudation) or fusion type B line (alveolar infiltration) and lung consolidation (alveolar collapse). With the improvement of the disease, the range of lung consolidation seen in LUS was reduced, the B-line was gradually sparse to dissipate, and the A-line appeared. Conclusions The results of LUS and chest CT in the same period are consistent. LUS examination is safe, simple, reproducible, and can be monitored dynamically in real time. It can be used as a primary screening method, and also be used in special patients to assist clinical treatment decision-making.

融合基因是指两个独立基因的编码区首尾相连所形成的且置于同一套调控序列控制的产物,研究表明许多癌症的发生与融合基因存在密切的联系。融合基因可作为癌症治疗的靶点,在癌症诊断及治疗领域中融合基因的研究具有重要意义。部分融合基因驱动癌症的机制已被初步揭示,但是有些真实存在的在肿瘤发生发展过程中有重要意义的融合基因由于工具和实验技术限制还未被发现。因此,对融合基因的分析预测研究方法逐渐成为关注的热点之一。本文探讨了目前常用的关于融合基因的分析工具及方法,为融合基因在癌症中的研究提供思路。

Fusion genes are the products of two independent genes whose coding regions are linked and controlled by the same set of regulatory sequences．Studies have shown that many cancers are closely linked to gene fusions．Fusion genes can be used as targets for cancer therapy,and the study of fusion genes is of great importance in cancer diagnosis and treatment．Some of the mechanisms of fusion genes driving cancer have been initially revealed,but there are more fusion genes which are important in the process of tumor development have not been discovered due to the limitation of tools and experimental techniques．Therefore,the analysis and prediction methods of fusion genes are becoming a hot topic of interest．In this paper,we discuss the commonly used analytical tools and methods on fusion genes to provide ideas for the study of fusion genes in cancer．
