医学论文的摘要部分如何用英语表达？

The abstract section of a medical paper is a crucial component that provides a concise overview of the study's objectives, methods, results, and conclusions. Writing an effective abstract in English requires careful consideration of the content and structure. Below is a detailed guide on how to express the abstract part of a medical paper in English.

1. Start with a Brief Introduction
   The first sentence of the abstract should introduce the study's topic and its significance. This can be achieved by stating the research question or hypothesis. For example:

• "This study investigates the impact of a new therapeutic regimen on the treatment of chronic obstructive pulmonary disease (COPD)."

1. Describe the Methods
   In the next paragraph, describe the methods used in the study. It is important to provide enough detail for readers to understand the study design and procedures. However, avoid excessive technical jargon. Here is an example:

• "A randomized controlled trial was conducted to compare the efficacy of the new regimen with the standard treatment. Participants were enrolled from four hospitals and were randomly assigned to either the experimental group (n=200) or the control group (n=200). The study lasted for 12 months, and data were collected at baseline and at the end of the study period."

1. Present the Results
   The results section should highlight the key findings of the study. It is important to use clear and concise language to avoid ambiguity. Here is an example:

• "The results showed that the new regimen significantly improved lung function (p<0.05) and reduced the frequency of exacerbations compared to the standard treatment. The mean forced expiratory volume in one second (FEV1) increased from 40% to 55% in the experimental group, while it remained unchanged in the control group."

1. Discuss the Conclusions
   The last paragraph of the abstract should summarize the main conclusions of the study. This section should reiterate the significance of the findings and their implications for the field. Here is an example:

• "These findings suggest that the new therapeutic regimen is a promising treatment option for COPD patients, as it improves lung function and reduces the frequency of exacerbations. Further research is needed to confirm these results and to investigate the long-term effects of the regimen."

Additional Tips for Writing a Medical Abstract in English:

1. Follow a Standard Structure
   Most medical abstracts follow a standard structure: introduction, methods, results, and conclusions. This structure helps readers quickly understand the study's content.

2. Use Active Voice
   Active voice is preferred in medical writing as it is more direct and concise. For example, "The new regimen was effective" is better than "Effectiveness of the new regimen was demonstrated."

3. Avoid Redundancy
   Be concise and avoid repeating information already mentioned in previous paragraphs. This will help keep the abstract focused and easy to read.

4. Use Keywords
   Include relevant keywords in the abstract to improve its visibility in databases and search engines. These keywords should reflect the main themes of the study.

5. Proofread and Edit
   Before submitting the abstract, proofread and edit it for grammar, punctuation, and clarity. It is also helpful to have a colleague or mentor review the abstract to ensure its effectiveness.

In conclusion, writing an effective abstract for a medical paper in English requires a clear and concise presentation of the study's objectives, methods, results, and conclusions. By following the tips outlined above, researchers can create an abstract that effectively communicates their findings to the scientific community.
