What was your hypothesis or purpose? Methods What did you do? Results What did you find? Discussion What do your findings mean? The Results section 解 螺 旋|陪 伴 医 生 科 研 成 长 英语科研写作 Results To provide a straightforward account of your findings. Dont describe Methods in detail in the Results section. But: A reminder of the method is helpful: “Western blotting revealed that protein levels were higher in A cells than in B cells.” Dont interpret findings in depth in the Results section. But: Briefly summarizing the finding is helpful: “These results suggested that Abc promoted metastasis of adenocarcinoma cells.” 解 螺 旋|陪 伴 医 生 科 研 成 长 英语科研写作 Results One by one, describe the findings for each experiment or analysis. Use subheadings, if possible. 解 螺 旋|陪 伴 医 生 科 研 成 长 英语科研写作 Results写作模板 开始: 提示读者实验目的（为何要进行这项实验？） “Western blotting revealed that.” “To evaluate the expression of ABC, we performed qRT-PCR in ” 中间: Report findings, referring to figures and tables as appropriate “. protein levels were higher in A cells than in B cells. Figure 1 shows the results of one representative experiment.” 结束: What is most important? Brief interpretation of the findings “These results indicated that agent X upregulated protein expression in A cells but not in B cells.” 解 螺 旋|陪 伴 医 生 科 研 成 长 英语科研写作 时态 Use the past tense “Serum levels of Her-2/neu correlated with disease-free survival.” “PCR analysis showed that 3 genes were expressed.” Avoid present tense in Results. Used to describe established fact: “DNA has a double-helix structure.” Used to describe general conclusions: “We conclude that the side effect profile of this new drug is superior to that of the other drug.” Results里不应出现 established facts / general conclusions. Figures and tables 解 螺 旋|陪 伴 医 生 科 研 成 长 英语科研写作 Figures and tables 能用一两句话描述的结果，用文字描述。否则尽量用图表。 “A figure is worth a thousand words.” 用图表传达复杂、重要的信息 在文字中提炼描述最重要的结果，而不是再复述一遍图表的内容（避免不必 要的重复） help the readers to locate the most important results 图表的内容也要避免重复 解 螺 旋|陪 伴 医 生 科 研 成 长 英语科研写作 Figures and tables Diluted carbapenemase plasmids (105 copies/ L) and negative controls with no template were used to evaluate how the microarray assays performed as far as repeatability is concerned. Experiments were repeated three times and repeatability was calculated for intra-chip and inter- chip experiments. The averaged coefficient of variations for inter-chip and intra-chip experiments remained low (less than 15%), suggesting a favorable repeatability of the DNA microarray detection method (Table 3).

Text Option B: Stage IV disease was rare in both groups (Table 1). Text Option C: Similar proportions of patients in groups A and B had clinical stage IIIa, IIIb, and IV disease (Table 1). 解 螺 旋|陪 伴 医 生 科 研 成 长 英语科研写作 Figures and tables Knocking down PTK7 decreases cellular migration in vitro To evaluate the role of PTK7 in tumor invasion, we compared the migration of siPTK7and siControl cells in vitro. Transwell migration assay showed that, in both cases of TE-5 and TE-9, migration ofsiPTK7 cells was significantly reduced by 60% or more compared with siControl (p 0.01) (Fig. 4), suggesting a promoting role of PTK7 in esophageal squamous carcinoma invasion. Interestingly, E- cadherin level was upregulated in siPTK7 cells (Fig. 4, Western blots), further suggesting PTK7 may promote cell migration through down- regulating epithelial-mesenchymal transition (EMT)-related pathways (see Discussion). Tips for writing Results section 解 螺 旋|陪 伴 医 生 科 研 成 长 英语科研写作 Limiting the Number of Figures and Tables Too many figures/tables distractions to readers 类似的结果 consider showing the result for only 1: Western blot analyses showing higher expression of total protein Z in group 1 (top) than in group 2 (bottom). Data are representative of similar results obtained in 3 independent experiments performed for both groups. 解 螺 旋|陪 伴 医 生 科 研 成 长 英语科研写作 “Data Not Shown” Use when you have Findings that dont require exact numbers Similar findings Results of routine assays Example: “In the tumor-bearing nude mice, virus titers were significantly higher in the brain than in the bone marrow, spleen, liver, testes, or ovaries (Table 1). Patterns of infectivity were the same in the nontumor-bearing nude mice (data not shown).” 解 螺 旋|陪 伴 医 生 科 研 成 长 英语科研写作 “Unpublished Data” Used to refer to a finding from another study (yours or someone elses) that has not yet
