科学家发现与创伤和抑郁症相关的脑化学物质

* Draft: 研究人员发现，一种名为 SGK1 的应激相关蛋白的高水平与经历过早年逆境的人群中的抑郁症密切相关。 * Refinement: "Endured early-life adversity" -> 经历早年逆境. "Closely associated" -> 密切相关. * "This discovery opens the door to a new type of antidepressant that blocks SGK1 activity and may be more effective for people who were neglected or abused as children." * Draft: 这一发现为一种新型抗抑郁药打开了大门，这种药物能阻断 SGK1 活性，对于那些童年时期被忽视或受虐待的人可能更有效。 * *Para 2:* "Studies show that about 60% of adults in the United States diagnosed with major depression and roughly two-thirds of those who attempt suicide experienced some form of trauma or adversity during childhood." * Draft: 研究表明，在美国被诊断患有重度抑郁症的成年人中，约 60% 的人以及约三分之二的自杀未遂者在童年时期经历过某种形式的创伤或逆境。 * *Para 3:* "Current antidepressants are often less effective for people with a history of childhood adversity, who represent a large proportion of adults with depression," says the study's lead author, Christoph Anacker, assistant professor of clinical neurobiology in the Department of Psychiatry at Columbia University Vagelos College of Physicians and Surgeons. * Draft: “目前的抗抑郁药对于有童年逆境史的人往往效果较差，而这部分人在成年抑郁症患者中占了很大比例，”该研究的主要作者、哥伦比亚大学瓦格洛斯内科与外科医学院精神病学系临床神经生物学助理教授 Christoph Anacker 说道。 * "What's exciting about our study is that it raises the prospect of quickly developing new treatments, as SGK1 inhibitors are in development for other conditions, and gives us a screening tool to identify people at greatest risk." * Draft: “我们研究的令人兴奋之处在于，它提出了快速开发新疗法的前景，因为 SGK1 抑制剂正在针对其他疾病进行开发，同时也为我们提供了一种筛查工具，用于识别风险最高的人群。” * *Heading 1:* "Why Depression After Early Trauma May Be Different" * Draft: **为何早期创伤后的抑郁症可能有所不同** * *Para 4:* "Childhood adversity (such as physical abuse or growing up in a dysfunctional family) is one of the strongest predictors of depression in adulthood." * Draft: 童年逆境（如身体虐待或在功能失调的家庭中成长）是成年期抑郁症最强的预测因素之一。 * *Para 5:* "While common antidepressants like SSRIs are helpful for many people, they are less effective for those who experienced early trauma." * Draft: 虽然 SSRIs（选择性5-羟色胺再摄取抑制剂）等常见抗抑郁药对许多人有帮助，但对于那些经历过早期创伤的人来说，效果较差。 注明: It's better to keep the acronym SSRIs or translate it. Usually, keeping SSRIs is fine, or adding the Chinese full name. I will use "SSRIs 等常见抗抑郁药". * "This suggested to us that the biological processes that lead to depression and suicidality in general may differ from those with less stressful childhoods," Anacker explains. * Draft: Anacker 解释说：“这向我们表明，导致抑郁症和自杀倾向的生物学过程，在一般人群中可能与那些童年压力较小的人群有所不同。” Wait, the English says "differ from those with less stressful childhoods". It implies: Processes in trauma patients differ from processes in non-trauma patients. * Correction: “这向我们表明，导致（此类人群）抑郁症和自杀倾向的生物学过程，可能与那些童年压力较小的人有所不同。” * *HTML Tag:* ` ` -> Keep as is. * *Para 6:* "Around ten years ago, Anacker's team discovered unusually high levels of SGK1 -- a stress-responsive protein -- in the blood of unmedicated patients with depression." * Draft: 大约十年前，Anacker 的团队在未接受药物治疗的抑郁症患者血液中发现了异常高水平的 SGK1——一种应激反应蛋白。 * *Heading 2:* "Evidence of SGK1's Role in Depression and Suicide" * Draft: **SGK1 在抑郁症和自杀中作用的证据** * *Para 7:* "In the latest research, the scientists examined the brains of adults who had died by suicide and found elevated SGK1 levels." * Draft: 在最新的研究中，科学家检查了死于自杀的成年人的大脑，发现 SGK1 水平升高。 * "Those who had suffered childhood trauma showed the highest concentrations, up to twice as much as others who had also died by suicide." * Draft: 那些遭受过童年创伤的人表现出最高的浓度，高达其他同样死于自杀者的两倍。 * *Para 8:* "The researchers also studied children exposed to early adversity and discovered that those carrying genetic variants that increase SGK1 production were more likely to experience depression as teenagers." * Draft: 研究人员还研究了暴露于早期逆境的儿童，发现那些携带增加 SGK1 产生的基因变异的人，在青少年时期更有可能经历抑郁症。 * "These findings point to SGK1 as a biological driver of depression and suicidal behavior, particularly among people affected by trauma early in life." * Draft: 这些发现表明 SGK1 是抑郁症和自杀行为的生物学驱动因素，特别是在生命早期受创伤影响的人群中。 * *Heading 3:* "Developing a New Kind of Antidepressant" * Draft: **开发一种新型抗抑郁药** * *Para 9:* "Based on these results, Anacker and his colleagues suggest that drugs designed to block SGK1 might * *Draft:* SGK1抑制剂已在接受评估，用于包括房颤在内的其他疾病。 * *Refinement:* "正在接受评估" or "正处于评估阶段". "用于治疗" is implied. * *Final:* SGK1抑制剂目前已在接受评估，用于治疗包括心房颤动在内的其他疾病。 * *Sentence 2:* "Anacker's team now hopes to begin clinical trials in people who have depression and a background of early life adversity." * *Key terms:* Anacker's team (Anacker的团队), clinical trials (临床试验), depression (抑郁症), background of early life adversity (早年生活逆境背景/经历). * *Draft:* Anacker的团队现在希望开始在患有抑郁症且有早年生活逆境背景的人群中进行临床试验。 * *Refinement:* "早年生活逆境经历" sounds slightly better than "背景". * *Final:* Anacker的团队目前希望针对患有抑郁症且有早年生活逆境经历的人群开展临床试验。 * *Sentence 3:* "The researchers also propose that genetic screening could identify individuals most likely to benefit from an SGK1-targeted antidepressant." * *Key terms:* genetic screening (基因筛查), identify (识别/鉴定), individuals (个体/人群), benefit from (受益于), SGK1-targeted antidepressant (靶向SGK1的抗抑郁药物). * *Draft:* 研究人员还建议，基因筛查可以识别出最可能从靶向SGK1的抗抑郁药物中受益的个体。 * *Refinement:* "Propose" here means suggest/put forward the idea. "建议" or "提出". "提出" fits scientific context well. * *Final:* 研究人员还提出，基因筛查或许能识别出最有可能从靶向SGK1的抗抑郁药物中受益的个体。 * *Sentence 4:* "'There's an urgent need to identify and treat people with the greatest risk of depression and suicide after exposure to early life adversity and SGK1 is a promising avenue to explore,' Anacker says." * *Key terms:* urgent need (迫切需求), exposure to early life adversity (遭受早年生活逆境), promising avenue (有前景的途径/方向). * *Draft:* “迫切需要识别并治疗那些在遭受早年生活逆境后面临最高抑郁和自杀风险的人群，SGK1是一个值得探索的有前景的途径，”Anacker说。 * *Refinement:* "Promising avenue to explore" -> "充满希望的探索途径" or "有前景的研究方向". * *Final:* Anacker表示：“迫切需要识别并治疗那些在遭受早年生活逆境后面临最高抑郁和自杀风险的人群，而SGK1是一条充满希望的探索途径。” * *Sentence 5:* "The research, titled 'Hippocampal SGK1 promotes vulnerability to depression: the role of early life adversity, stress, and genetic risk,' was published in *Molecular Psychiatry*." * *Key terms:* Hippocampal (海马体的/海马), vulnerability to depression (抑郁易感性/抑郁症的脆弱性), early life adversity (早年生活逆境), stress (压力), genetic risk (遗传风险), *Molecular Psychiatry* (《分子精神病学》). * *Title Translation:* "Hippocampal SGK1 promotes vulnerability to depression: the role of early life adversity, stress, and genetic risk" -> 《海马SGK1促进抑郁症易感性：早年生活逆境、压力和遗传风险的作用》。 * *Draft:* 这项题为“海马SGK1促进抑郁症易感性：早年生活逆境、压力和遗传风险的作用”的研究发表在《分子精神病学》上。 * *Final:* 这项题为《海马SGK1促进抑郁症易感性：早年生活逆境、压力和遗传风险的作用》的研究发表在《分子精神病学》（*Molecular Psychiatry*）杂志上。 (Keeping the English journal name in brackets is standard practice, or just the Chinese name. I will use the standard Chinese translation). * *Sentence 6:* "Authors include Amira Millette (Columbia), Milena T. van Dijk (Columbia), Irina Pokhvisneva (McGill), Yifei Li (Columbia), Rory Thompson (Columbia), Sachin Patel (McGill), Rosemary C.

Standard practice in academic lists is often to keep names in English or transliterate. I will keep names in English for accuracy, as transliteration can be ambiguous). Institutions should be translated. * *Final:* 作者包括：Amira Millette（哥伦比亚大学）、Milena T. van Dijk（哥伦比亚大学）、Irina Pokhvisneva（麦吉尔大学）、Yifei Li（哥伦比亚大学）、Rory Thompson（哥伦比亚大学）、Sachin Patel（麦吉尔大学）、Rosemary C.
