In recent years,terahertz (THz) technology has made significant progress in numerous applications;however,the highly sensitive,room-temperature THz detectors are still rare,which is one of the bottlenecks in THz *** this paper,we proposed a room-temperature electrometry method for THz detection by laser spectroscopy of cesium(^(133)Cs) Rydberg atoms,and conducted a comprehensive investigation of the five-level system involving electromagnetically induced transparency (EIT),electromagnetically induced absorption (EIA),and Autler–Townes (AT) splitting in^(133)Cs *** solving the Lindblad master equation,we found that the influence of the THz electric field,probe laser,dressing laser,and Rydberg laser on the ground state atomic population as well as the coherence between the ground state and the Rydberg state,plays a crucial role in the transformation and amplitude of the EIT and EIA *** and the atomic vapor cell’s dimensions affect the number of^(133)Cs atoms involved in the detection,and ultimately determine the *** predicted the proposed quantum coherence THz detection method has a remarkable sensitivity of as low as 10^(-9)V m^(-1)Hz^(-1/2).This research offers a valuable theoretical basis for implementing and optimizing quantum coherence effects based on Rydberg atoms for THz wave detection with high sensitivity and room-temperature operation.

Objective: To clarify the role of the “Three Threes” method in clinical teaching of internal jugular vein puncture and explore improvements in teaching methods. Methods: A doctor was assigned to the induction room of the Second Affiliated Hospital of Naval Medical University (Shanghai Changzheng Hospital) for two months. The time required for catheterization, the first puncture success rate, and occurrence of puncture-related complications were compared before and after learning the “Three Threes” method. Results: Using the “Three Threes” method reduced the catheterization time by 43%, increased the first puncture success rate by 17%, and led to fewer puncture-related complications. Conclusion: The application of the “Three Threes” method not only improves the success rate of internal jugular vein puncture but also reduces complications, making it easier for students to master the technique.

Background: Pericardial effusion may progress to cardiac tamponade when pressure around the heart increases to a level comparable to that of the right and left atria. Patients with cardiac tamponade need timely completion of emergency pericardiocentesis to relieve the threat to the patient’s life, and to save valuable time for patients who need emergency thoracotomy and pericardial window drainage. Pericardiocentesis is a necessary clinical skill for residents in standardized training. In addition, nurses who are familiar with this technology can better assist clinicians to perform this operation. In order to make the medical staff quickly master the theoretical knowledge of emergency pericardiocentesis, we designed a “1 + 1 + 1” teaching method for the theoretical teaching of emergency pericardiocentesis. Objective: This study aims to explore the effectiveness of the “1 + 1 + 1” teaching method in the theoretical teaching of emergency pericardiocentesis. Methods: We used an English teaching video of emergency pericardiocentesis and applied the “1 + 1 + 1” teaching method for theoretical teaching. A questionnaire survey was conducted before and after the lecture among 19 medical staff of different years of service to understand their mastery of the theoretical content of emergency pericardiocentesis before and after the lecture. According to the years of service, the medical staff were divided into three groups: 1 - 3 years (Group A), 4 - 10 years (Group B), and over 10 years (Group C), and the changes in the mastery of various contents by the overall medical staff and each group were statistically analyzed. Results: Before the lecture, the number of people who mastered the indications, contraindications, most commonly used methods, and common complications of emergency pericardiocentesis were 15, 12, 16, and 17, respectively, whereas after the lecture, these numbers increased to 17, 19, 19, and 19, respectively. The overall mastery before and after the lecture was

采用计算流体力学方法(CFD)对三种不同类型的T型微混合器的被动式混合进行了数值模拟。分析了简单微混合器内混合指数和压降与入口速度、扩散系数和管径之间的关系,同时研究了含有内构件混合器中结构参数对混合的影响。研究结果表明,层流状态下,在简单混合器中,混合指数随着Reynolds数Re、Schmidt数Sc和Peclet数Pe的增大而增大,同时压降随Re的增大而增大、随Pe的增大而减小。在T型混合器内加入肋板和障碍物后,混合指数随Re的增大先增大后减小;肋板长度越长,障碍物内径越大,混合效果越好,但相应的压降也越大。

目的:探讨运动主体在不同时间的低温高湿暴露环境中血糖的变化规律。方法:采用文献资料法、实验法、数理统计法等研究方法,以低温雨雪冰冻天气作为实验模拟环境,以小鼠为实验对象。根据体质量随机分为常温常湿1.5 h组、低温高湿1.5 h组、常温常湿2 h组、低温高湿2 h组、常温常湿3 h组、低温高湿3 h组、常温常湿4 h组、低温高湿4 h组。各组连续间断暴露7天并禁食12 h后,第8天进行力竭游泳实验并测血糖。结果:与常温常湿组对比,低温高湿1.5 h、低温高湿4h组血糖浓度均升高,且低温高湿4 h组有显著性差异(P<0.01);低温高湿2h组、低温高湿3h组血糖浓度均下降,且低温高湿2 h组有显著性差异(P<0.05)。结论:在不同时间的低温高湿环境暴露下,小鼠的血糖浓度会出现不同的变化,其中低温高湿4 h组的血糖浓度变化最为显著,表明低温高湿环境对机体的血糖调节有明显影响,且暴露时间和强度是影响血糖变化的重要因素。本文研究对运动员、教练员或长期从事低温作业的人群掌握低温高湿环境下血糖的变化规律,合理调整饮食和运动计划具有一定的参考意义。
