When talking about my research experience, I am overwhelmed. I have participated in many projects, and each project brings me different feelings. The first time I did scientific research was the school's "Challenge Cup" research project. Although I got a lot of guidance from the teachers and the experimental process was relatively smooth, I did not encounter no problems. The biggest difficulty was the time-consuming nature of the experiment and the high concentration required during the antibody staining process. It takes a whole day to do one experiment, and each experiment has to do five different protocols at the same time, sometimes dozens of tubes of samples at a time, so you have to be very careful when doing the antibody staining, and the slightest negligence may lead to the end of your work. When I first started to do the experiment, because I was not familiar with the experimental operation, I often added the wrong reagent or the staining result was unsatisfactory, which led to the day's hard work being wasted. However, through repeated practice, I gradually mastered the operation skills and overcame these difficulties. Another project was my graduation design, which was also a challenging process. The experiment itself was not difficult; the biggest problem was the use of statistical methods. Through this project, I gained insight into the differences between different statistical methods and the problem of false positives. When analyzing the data, I found that the results were statistically different when analyzing the experimental and healthy control groups of CHI3L1 using the U test alone, but not in the Kruskal-Wallis[No Replacement Word Found](misspelling) multiple comparison test. Even the serum CJI3L1 levels of asthmatics in the disease control group did not differ, which is not consistent with the results in the literature. It may be due to the fact that I compared 7 groups at the same time in the multiple comparisons test, which reduced the specificity of the test and made the results conservative, i.e., I may have missed some of the differences that actually existed. This made me realize that in scientific research, the importance of statistical analysis should not be underestimated in addition to experimental design and implementation. In the process of working as a research assistant in HuanglabHuang lab(misspelling), I faced a series of problems and difficulties. First of allFirst(first of all (first)), since no one in this lab had ever done this experiment of in vitro phase separation of proteins before, there was no one to ask for advice, so we had to figure it out by ourselves. We tried various experimental methods and steps, such as changing the temperature, PH, salt concentration, protein concentration and the order of reagents added in the experiment, but none of them gave us the phase change protein we expected. This gave me a lot of frustration and, and(comma between independent clauses) it seemed like everything was being tried blindly. In addition, the lab did not have equipment that could do FRAPRAP(misspelling) experiments, and we needed to book the school's communal equipment for doing FRAPRAP(misspelling) experiments in advance, so the time available to do the experiments was very limited each time. In order to make full use of this limited time, we usually need to work overtime at night, even until midnight. Such hard work and dedication without getting any results made me want to give up from time to time, feeling that it was an impossible task. One time when it never got done, I even added my own unfinished coffee to it, hahaha. By constantly reflecting and summarizing the experimental results and improving the experimental scheme, one day, through our unremitting efforts, we finally made it. This experimental experience made me deeply realize the nature of scientific research: it is a long and arduous battle that requires us to invest a lot of time, energy and patience. Scientific research is a pursuit of truth and breakthroughs. Success is not easy to come by, but requires firm beliefs and unremitting efforts. Every failure is a valuable experience, and they make me more humble and grow. I have learned to learn from my failures, adjust my methods and thoughts, and continue to move forward. Looking forward to the future, I am willing to continue to explore the academic field as far as possible and contribute my share to scientific research.

Reflecting on my research experience, I am filled with a sense of accomplishment and growth. Throughout my academic journey, I have participated in numerous projects, each offering unique insights and challenges. In this essay, I will provide an overview of my research background and delve into the details of one specific project, discussing its goals, challenges encountered (and how I overcame them), results, and significance.

My first foray into scientific research was during the school's "Challenge Cup" project, which aimed to explore the potential applications of nanotechnology in environmental protection. Although I received ample guidance from my teachers and the experimental process went relatively smoothly, it was not without its difficulties. The most significant challenge was the time-consuming nature of the experiment and the high level of concentration required during antibody staining. Each experiment took an entire day to complete, with multiple protocols running simultaneously. This demanded meticulous attention to detail to avoid any errors that could jeopardize the entire process. Initially, due to my unfamiliarity with experimental procedures, I often added incorrect reagents or obtained unsatisfactory staining results. However, through repeated practice and perseverance, I gradually mastered the necessary skills and overcame these obstacles.

After gaining experience from the "Challenge Cup" project, I faced another challenge during my graduation design – a project focused on developing a new diagnostic tool for early detection of lung cancer. The primary goal was to improve the accuracy and efficiency of current diagnostic methods. Although the experiment itself was not overly complicated, employing statistical methods proved to be quite challenging. Through this project, I gained insight into various statistical techniques and their potential pitfalls such as false positives.

When analyzing data from CHI3L1 experimental and healthy control groups using only U-test analysis revealed statistically significant differences; however, these differences were not apparent when using Kruskal-Wallis multiple comparison tests. This discrepancy may be attributed to comparing seven groups simultaneously in the multiple comparison test, which reduced the specificity of the test and made the results conservative. This experience underscored the importance of statistical analysis in scientific research, in addition to experimental design and implementation.

Following my graduation project, I had the opportunity to work as a research assistant in Huanglab, where I encountered a new set of challenges and difficulties. Since no one in the lab had previously conducted experiments on in vitro phase separation of proteins, we had to explore various methods independently. We experimented with different temperatures, pH levels, salt concentrations, protein concentrations, and reagent addition sequences but failed to achieve the desired phase-separated proteins. This trial-and-error process was frustrating and often felt like groping in the dark.

Additionally, our lab lacked equipment for FRAP experiments, so we had to reserve shared equipment at our school. Consequently, our experiment time was limited and often required working late into the night. Despite these setbacks and moments of doubt, we persisted in refining our experimental approach until we finally achieved success.

These research experiences have instilled in me a deep understanding of scientific research's nature: it is a long and arduous journey that demands time, energy, and patience. Success is rarely achieved easily; it requires unwavering dedication and continuous effort. Each failure serves as a valuable lesson that fosters humility and growth. Through these experiences, I have learned to embrace failure as an opportunity for improvement – adjusting my methods and mindset while pressing forward.

As I look towards my future academic endeavors, I am eager to continue exploring uncharted territories within my field of study while contributing meaningfully to scientific research. (589 words)
