IntroductionBasic medical education serves as the foundation for the development of competent healthcare professionals who are equipped with the knowledge, skills, and ethical principles necessary to provide optimal patient care. The pursuit of high-quality and high-standard education in this field is paramount, given its direct impact on public health and the overall wellbeing of society. This essay provides a comprehensive, multifaceted analysis of the key elements that define and contribute to the quality and standard of basic medical education, emphasizing the importance of curriculum design, pedagogical approaches, assessment strategies, clinical exposure, research integration, and continuous professional development.I. Curriculum Design and ContentThe quality and standard of basic medical education are fundamentally shaped by the curriculum, which should be comprehensive, up-to-date, and responsive to the evolving needs of healthcare systems. A high-quality curriculum should encompass a broad range of disciplines, including anatomy, physiology, biochemistry, pharmacology, pathology, microbiology, immunology, and behavioral sciences, ensuring students acquire a solid understanding of the fundamental principles underlying human health and disease.Moreover, a forward-thinking curriculum should incorporate emerging areas such as genomics, personalized medicine, public health, health informatics, and global health, reflecting the dynamic nature of medical practice. Integration of these subjects within a systems-based or problem-based learning approach fosters interdisciplinary connections and promotes the development of critical thinking skills essential for life-long learning and adaptation to new medical discoveries.II. Pedagogical Approaches and Teaching StrategiesEffective pedagogy lies at the heart of delivering high-quality, high-standard basic medical education. Innovative teaching methods, such as active learning, flipped classrooms, team-based learning, and simulation-based education, foster student engagement, enhance knowledge retention, and promote the acquisition of practical skills. These approaches encourage self-directed learning, collaboration, and the application of theoretical concepts to real-world scenarios, aligning with the principles of adult learning theory and the increasing demand for competency-based education.Furthermore, the integration of technology, such as e-learning platforms, virtual reality, and telemedicine simulations, enriches the learning experience, facilitates access to resources, and enables remote learning opportunities. The judicious use of technology can also support diverse learning styles, accommodate individual differences, and promote inclusivity, contributing to the overall standard of education.III. Assessment Strategies and Feedback SystemsAssessment is a crucial component of maintaining high standards in basic medical education, serving not only to evaluate student performance but alsoto drive learning and improvement. A robust assessment framework should encompass a blend of formative and summative assessments, incorporating various modalities such as written exams, oral presentations, practical skills assessments, reflective portfolios, and objective structured clinical examinations (OSCEs). This holistic approach ensures that students are evaluated on a wide range of competencies, including knowledge, critical thinking, communication, professionalism, and clinical skills.Timely, constructive, and individualized feedback is vital for student growth and the maintenance of high standards. Effective feedback systems should involve both peers and faculty, fostering a culture of peer-assisted learning and continuous improvement. Regular self-assessment and personal development planning further empower students to take ownership of their learning, aligning with the principles of self-regulated learning and lifelong professional development.IV. Clinical Exposure and Early Patient ContactExposure to clinical environments and early patient contact is indispensable for the development of competent, empathetic physicians. High-quality basic medical education should provide ample opportunities for students to observe and participate in patient care under supervised conditions, gradually assuming greater responsibility as they progress through their studies. This hands-on experience enhances the translation of theoretical knowledge into clinical practice, fosters the development of clinical reasoning skills, and promotes the cultivation of professionalism and empathy.Interprofessional education (IPE) initiatives, where students from various healthcare disciplines learn and work together, further enhance the quality and standard of clinical training. IPE promotes understanding of team dynamics, effective communication, and collaborative decision-making, preparing future healthcare professionals for the realities of interdisciplinary patient care.V. Research Integration and Evidence-Based PracticeIncorporating research into basic medical education is essential for fostering a spirit of inquiry, critical appraisal skills, and evidence-based practice. Students should be exposed to research methods, biostatistics, and epidemiology, and encouraged to engage in research projects, either independently or collaboratively with faculty members. This exposure not only enhances their understanding of the scientific foundations of medicine but also equips them with the skills necessary to appraise and apply new evidence to their future clinical practice.Moreover, integrating research findings and best practices into the curriculum ensures that students learn from the most current and reliable sources, reinforcing the high standard of their education. Encouraging students to attend conferences, workshops, and journal clubs further enriches their research experience and fosters a commitment to lifelong learning and continuous professional development.VI. Continuous Professional Development and Lifelong LearningIn an era of rapid advancements in medical knowledge and technology, the ability to adapt and continuously learn is crucial for healthcare professionals. High-quality basic medical education should instill in students a strong commitment to lifelong learning, equipping them with the skills and mindset required to stay abreast of new developments and maintain their competence throughout their careers.This can be achieved through the integration of self-directed learning strategies, the promotion of reflective practice, and the provision of opportunities for continued education and professional development. Moreover, institutions should foster a supportive learning environment that encourages alumni engagement, mentorship, and networking, facilitating the exchange of knowledge and experiences among current and future generations of healthcare professionals.ConclusionAchieving high-quality and high-standard basic medical education necessitates a holistic approach that encompasses a well-designed, comprehensive curriculum; innovative pedagogical strategies; robust assessment frameworks; ample clinical exposure; integration of research and evidence-based practice; and a strong emphasis on continuous professional development. By diligently addressing these multifaceted aspects, educational institutions can ensure that their graduates are well-prepared, adaptable, and committed healthcare professionals, poised to deliver optimal patient care and contribute positively to the advancement of healthcare systems worldwide.。
·药物临床·精神分裂症和双相情感障碍可否共病？甘鸿文竹胡瑶王韵吴彦（上海交通大学医学院附属精神卫生中心心境障碍科上海 200030）摘要精神分裂症和双相情感障碍在当前主流的疾病诊断与分类系统中分属不同的诊断单元。
目前常见的观点认为，一个患者不会同时罹患这两种疾病，即这两种疾病不共病。
但临床上发现，这两种疾病存在许多共通点，即一个患者会同时或不同时出现这两种疾病的典型症状。
本文依据既往相关研究结果，探讨精神分裂症和双相情感障碍共病的可能性。

The current common view is that patients do not suffer from the two disorders simultaneously, that is, the two disorders are not comorbid. However, it is clinically found that these two disorders have many things in common, that is, a patient will simultaneously have the typical symptoms of the two disorders or not. This paper reviews the previous studies and discusses the possibility of comorbidity between schizophrenia and bipolar affective disorder.KEY WORDS schizophrenia; bipolar affective disorder; comorbidity精神分裂症和双相情感障碍是精神科的常见疾病[1-3]，目前主流的疾病诊断与分类系统《国际疾病分类（第10版）》[4]和《精神障碍诊断与统计手册（第5版）》[5]均将这两种疾病列为独立的诊断单元。
一个抑制肿瘤的连续模型-------艾丽斯H伯杰，阿尔弗雷德G. Knudson 与皮埃尔保罗潘多尔菲今年，也就是2011 年，标志着视网膜母细胞瘤的统计分析的第四十周年，首次提供了证据表明，肿瘤的发生，可以由两个突变发起。
这项工作提供了“二次打击”的假说，为解释隐性抑癌基因（TSGs）在显性遗传的癌症易感性综合征中的作用奠定了基础。
然而，四十年后，我们已经知道，即使是部分失活的肿瘤抑制基因也可以致使肿瘤的发生。
在这里，我们分析这方面的证据，并提出了一个关于肿瘤抑制基因功能的连续模型来全方位的解释肿瘤抑制基因在癌症过程中的突变。
虽然在1900 年之前癌症的遗传倾向已经被人认知，但是，是在19 世纪曾一度被忽视的孟德尔的遗传规律被重新发现之后，癌症的遗传倾向才更趋于合理化。
到那时，人们也知道，肿瘤细胞中的染色体模式是不正常的。
接下来对癌症遗传学的理解做出贡献的人是波威利，他提出，一些染色体可能刺激细胞分裂，其他的一些染色体 a 可能会抑制细胞分裂，但他的想法长期被忽视。
现在我们知道，这两种类型的基因，都是存在的。
在这次研究中，我们总结了后一种类型基因的研究历史，抑癌基因（TSGs），以及能够支持完全和部分失活的肿瘤抑制基因在癌症的发病中的作用的证据。
我们将抑制肿瘤的连续模型与经典的“二次打击”假说相结合，用来说明肿瘤抑制基因微妙的剂量效应，同时我们也讨论的“二次打击”假说的例外，如“专性的单倍剂量不足”，指出部分损失的抑癌基因比完全损失的更具致癌性。
这个连续模型突出了微妙的调控肿瘤抑制基因表达或活动的重要性，如微RNA（miRNA）的监管和调控。
最后，我们讨论了这种模式在┲⒌恼锒虾椭瘟乒 讨械挠跋臁！岸 未蚧鳌奔偎?第一个能够表明基因的异常可以导致癌症的发生的证据源自1960 年费城慢性粒细胞白血病细胞的染色体的发现。
后来，在1973 年，人们发现这个染色体是是第9 号和第22 号染色体异位的结果，并在1977 年，在急性早幼粒细胞白血病患者中第15 号和第17 号染色体易位被识别出来。

JOURNAL OF COMMUNICATION UNIVERSITY OF CHINA （SCIENCE AND TECHNOLOGY ）中国传媒大学学报（自然科学版）第27卷，第6期Vol 27，No 62020年12月Dec ，2020关于GPS 系统“相对论修正”问题的讨论黄志洵（中国传媒大学信息工程学院，北京100024）摘要：GPS 的运转依赖于绕地球旋转的卫星上的原子钟的精确性。
所谓相对论性修正包括狭义相对论（SR ）修正（－7μs /天）和广义相对论（GR ）修正（45．9μs /天），故净增量为约38μs /天。
相对论性预期是以时间延缓及引力势理论为基础的。
在Lorentz 理论中，时间延缓由动体的绝对运动引起。
相对于静止的时钟，绝对速度大的时钟变慢；这是Lorentz 以太论中的时间延缓。
但在SR 中用动体相对速度取代绝对速度，情况完全不同。
Einstein 是以不同观察者参考系的相对运动取代观察者与以太的关系，来解释长度缩短和时间延缓。
因而产生了许多悖论质疑SR 的自洽性，最著名的是P．Langevin 于1911年提出的双生子佯谬。
多年来的众多研究讨论显示，SR 存在逻辑上的不自洽，亦缺少真正确定的实验证实。
由此可以理解欧洲核子研究中心（CERN ）的著名科学家John Bell 在1985年所说的话：“我想回到Einstein 之前，即Poincarè和Lorentz ”，此外，本文着重指出引力势概念在理论上和实践中都不那么重要，因为它缺乏实验基础。
这与电磁学中的情况并不相同。
众所周知，Maxwell 方程组建筑在若干实验定律的基础上，电磁势概念很重要。
然而类电磁引力场方程组不满足这条件，故它不被事实所支持。
再者，Einstein 引力场方程（EGFE ）是GR 理论的基本方程，但它的推导有假设和拼凑的作法。
引力场的物理效果被认定由Riemann 空间的度规张量体现，需要知道度规场分布的规律。
生命是永恒不断的创造，因为在它内部蕴含着过剩的精力，它不断流溢，越出时间和空间的界限，它不停地追求，以形形色色的自我表现的形式表现出来。

The Industry Standard in 3D Ion and Electron Optics Simulations Scientific Instrument Services, Inc.1027 Old York Rd, Ringoes, NJ 08551Phone: (908) 788-5550Scientific Instument Services, Inc™ SIMION ™Version 8.1SIMION 8.1S IMION 8.1 is a software package used primarily to calculate electric fields, when given a configuration of electrodes withvoltages, and calculate trajectories of charged particles in those fields, when given particle initial conditions, including optional RF, magnetic field, and collisional effects are supported. In this, SIMION provides extensive supporting functionality in defin-ing your system geometry and conditions, recording and visualizing results, and extending the simulation capabilities with user pro-gramming. It is an affordable but versatile platform, widely used for over 35 years to simulate lens, mass spec, and other types of particle optics systems.Typical usage of SIMION is illustrated below for a simple three-element Einzel lens. The geometry consisting of three ring elec-trodes with given voltages is defined (top), and the fields and particle trajectories are calculated and displayed.Electrostatic field solving:SIMION solves fields in 2D and 3D arrays of up to nearbillions of points, with optimizations for systems with symmetry and mirroring, accord-ing to the finite difference method with much optimized linear-time solving. Smallarrays solve in under a minute; very large arrays may take roughly an hour depending onconditions. A “workbench” strategy allows you to position, size, and orient instances(3D images) of different grid densities and symmetries to permit the simulation of muchlarger systems that don't easily fit into a single array. Some magnetic field solving capa-bilities are also available (see following page).Particle trajectory solving: Particle trajectories are calculated given the previouslycalculated or defined fields. The method is Runge-Kutta with relativistic corrections andvariable-length dynamically adjusting and controllable time steps. Particle mass, charge,and other parameters can be defined individually or according to some pattern or distrib-ution. User programming can modify the system during particle flight to inject noveleffects (such ion-gas scattering). Particle tracing is fast _millions of particles can behandled—and they display in real-time. Basic charge repulsion effects, including a pois-son solver can help estimate the onset of space-charge.Viewing of the system is highly interactive, allowing adjustment of parametersand viewing of the system even during particle flight (trajectory calculation). SIMIONsupports cutting away volumes to see trajectories inside, zooming, viewing potentialenergy surfaces, contour lines, and trajectories, and reflying particles as dots for movieeffects.S IMION is suitable for a wide variety of systems: from ion flight through simple electrostatic and magnetic lenses to particle guns to highly complex instruments, including time-of-flight, hemispherical analyzers, ion traps, quadrupoles, ICR cells, and other MS, ion source and detector optics.Time-dependent or RF (low frequency) voltages:Electrode voltages may be controlled in a general way during particle flight via simple user programs _ e.g. to step or oscillate electrode voltages in some manner. Quadrupole mass filter, multipole, and ion trap simulations (above) in the megahertz range are regularly performed. SIMION applies the quasistatic approximation with superposition, which gives fast calculations (assuming the absence of induced magnetic field or radiation effects as would occur in “high frequency” systems having the wavelength below the length of your system).Magnetic fields: SIMION will import magnetic fields, define them analytically or solve them in restricted cases (e.g. Biot-Savart wire currents - left), optionally superimposed on an electrostatic field (e.g.penning trap or ICR cell - right) for the pur-pose of particle flying.ApplicationsRF Quad Mass Filter RF Ion Trap RF Ion Trap (Potential Energy Display)Ion Confinement in Air SolenoidICR CellIon-neutral collisions: SIMION can handle the effects of particles colliding against a background gas, such as for the buffer gas of the ion trap (top), the back-ground gas in an RF ion-funnel (right), or in ion mobility. Multiple collision models are included: Stokes' law, hard-sphere, and a mobility model optimized for high pres-sure “atmospheric” conditions. The parti-cles will diffuse and randomly scatter away from their normal trajectories.RF Ion Funnel Atmospheric Pressure ExampleDefine Your SimulationComplex CAD Modelimported from STL file(left) to a SIMION arrayGeometry (GEM) defi-nition file exampleGeometry definition: A system geometry can be defined by whichever method is most convenient for you: an interactive 3D paint-like program(called “Modify”), CAD import from STL format (supported by most CAD packages), a solid geometry defined mathe-matically via a text file(“GEM files”), and programmatic manipulation of arrays from such languages as Lua, Perl, Python, and C++.Particle initial conditions can be defined in various ways. The“FLY2” format in SIMION allows quick definition of many types ofparticles random distributions and sequences. Particles may also beexhaustively enumerated (optionally imported from a text file).Analysis and Programming SIMION has a number of capabilities for collecting data.•Package contents: a 450-page printed manual, installation CD with software license key number (for receiving softwareupdates), and quick start notes.

At left is a SIMION generated surface plot of beam size as a func-tion of two lens voltages. At right is one of the many user programming examples (scattering at surface).Programming in Lua Surface Plot in ExcelScattering Effects at Surface User programming allows the simulation to be extended in many novel ways. During ion flight, you may control electrode voltages (example at right), define or modify fields, scatter or deflect ions (e.g.ion-gas collision models), tune (optimize) lens voltages, compute results, export data to programs like Excel via COM or command-line interfaces, and do many other things. The Lua scripting language is directly embedded in SIMION, and Lua may also call C/C++ or COM routines. Programming may also be used to operate SIMION in batch mode , such as for geometry optimization or to read/manipu-late potential array files.Contents Data recording:The simulation parameters you are interested in (e.g. ion position, velocity, KE, and voltage) can be recorded at various stages in particle flight (e.g. when hitting an electrode and crossing a plane). Data can be recording to the screen or to delim-ited text file for subsequent analysis of fields and trajectories (right).

希望对您的长文撰写有所帮助！2. 正文一:2.1 主要观点一:One of the main points regarding the general theory is its application in the field of physics. The general theory, proposed by Albert Einstein, revolutionized our understanding of gravity and the structure of the universe. It introduced the concept of spacetime curvature caused by massive objects, explaining the force of gravity as a geometric effect rather than a conventional force.Additionally, the general theory also predicted the existence of black holes, which are incredibly dense objects with gravitational fields so strong that nothing can escape them, not even light. This prediction was later confirmed through various astronomical observations and experiments.2.2 主要观点二:Another important aspect to highlight is the impact of the general theory on cosmology - the study of the origin and evolution of the universe. According to this theory, the universe is not static but expanding. This insight led to groundbreaking discoveries such as the Big Bang theory, which suggests that our universe originated from an extremely hot and dense state billions of years ago.The general theory also provided a framework for understanding the distribution of matter in space and how it shapes cosmic structures like galaxies and galaxy clusters. Through its mathematical equations, scientists have been able to model and simulate these large-scale structures, further advancing our knowledge about the universe's composition and evolution.2.3 主要观点三:A third significant point pertains to technological applications stemming from the general theory. One notable example is GPS (Global Positioning System) technology. The accuracy of GPS relies on precise timing measurements using satellite signals traveling at high speeds relative to Earth's surface. However, without accounting for relativisticeffects predicted by Einstein's general theory, GPS calculations would yield errors exceeding several kilometers within just a day.By incorporating corrections based on relativistic principles into GPS algorithms, accurate positioning can be achieved. Therefore, it is evident that the general theory has real-world applications beyond scientific research, impacting everyday life and facilitating modern technologies.Overall, the general theory, with its profound implications in physics, cosmology, and technology, stands as one of the most well-known and influential concepts in scientific history. Its impact continues to shape our understanding of the universe and has broad applications that extend far beyond theoretical realms.3. 正文二3.1 主要观点一：在本部分中，我们将讨论关于"the most well-known being the general theory（最著名的是广义相对论）"的一些主要观点。
