抗逆转录病毒疗法是怎样把艾滋病从绝症变成可控慢性病的？
How did antiretroviral therapy turn HIV/AIDS from fatal to manageable?
Barré-Sinoussi 与 Montagnier 在 1983 年分离出 HIV；随后联合多种药物抑制逆转录酶和蛋白酶的组合疗法(HAART)能把病毒载量压到检测不到，令患者寿命接近常人。这使艾滋病从必然死亡转变为可控慢病。
Barré-Sinoussi and Montagnier isolated HIV in 1983; combination antiretroviral therapy (HAART) blocking reverse transcriptase and protease can suppress viral load to undetectable, giving near-normal life expectancy. AIDS shifted from inevitably fatal to a manageable chronic disease.

什么是噬菌体疗法，它为什么重新受到关注？
What is phage therapy, and why is interest reviving?
噬菌体是专门感染细菌的病毒，能识别特定菌株、在其体内复制并使之裂解。在抗生素普及前它就被尝试用于治疗感染，如今由于多重耐药菌日益严峻，噬菌体疗法作为补充手段在同情用药和临床试验中重新受到重视。它的优势是高度特异、不伤害正常菌群，还能随细菌进化而“共同进化”。难点在于宿主范围窄需要精准配型、可能被人体免疫系统清除、缺乏标准化生产与监管路径，因此目前仍属研究性治疗，而不是常规选项。
Bacteriophages are viruses that infect bacteria specifically, recognizing particular strains, replicating inside them and lysing them. They were tried against infections before antibiotics became widespread, and now, with multidrug-resistant bacteria spreading, phage therapy is being revisited in compassionate-use cases and clinical trials as a complementary option. Its attractions are high specificity that spares normal flora and the ability to co-evolve as bacteria change. The hurdles are a narrow host range requiring careful matching, clearance by the immune system, and the lack of standardized manufacturing and regulatory pathways - so it remains investigational rather than routine.

幽门螺杆菌是怎么被证明是胃溃疡真正病因的？
How was Helicobacter pylori proven to be the real cause of stomach ulcers?
Marshall 与 Warren 在 1982 年从胃炎患者胃黏膜中分离出弯曲杆菌，并以自身吞服细菌诱发胃炎的方式证明其与溃疡相关，颠覆了『溃疡源于压力与胃酸』的旧观念。二人因此获 2005 年诺贝尔奖。
Marshall and Warren isolated a curved bacterium from ulcer patients' gastric mucosa in 1982 and even swallowed it themselves to induce gastritis, proving its link to ulcers and overturning the old 'stress and acid' view. They won the 2005 Nobel Prize.

细菌为什么会产生抗生素耐药性，且能快速在菌种间传播？
Why do bacteria become antibiotic-resistant, and how does resistance spread so fast?
耐药可由随机突变或获得耐药基因产生，在药物选择压力下被保留放大；而质粒、转导和接合等水平基因转移能让耐药基因在物种间迅速共享。WHO 将其列为全球重大公共卫生威胁。
Resistance arises from random mutation or acquired resistance genes, then survives under drug selection; horizontal gene transfer via plasmids, transduction, and conjugation lets resistance genes spread quickly across species. The WHO calls it a major global health threat.

朊病毒是什么，它为什么挑战了『传染病必须有核酸』的观念？
What are prions, and why did they challenge the idea that infectious agents need nucleic acid?
朊病毒是错误折叠的蛋白质，能诱导体内正常的同源蛋白也发生错误折叠并聚集，造成脑组织的海绵状变性。Prusiner 在 1982 年提出这一无核酸的传染机制，获 1997 年诺贝尔奖。
Prions are misfolded proteins that induce normal homologous proteins to misfold and aggregate, causing spongiform degeneration of the brain. Prusiner proposed this nucleic-acid-free infectious mechanism in 1982 and won the 1997 Nobel Prize.

青蒿素是怎样治疗疟疾的，为什么屠呦呦的工作很重要？
How does artemisinin treat malaria, and why was Tu Youyou's work important?
青蒿素来自黄花蒿，能在疟原虫寄生红细胞时产生活性氧、破坏其蛋白而快速杀虫，尤其对耐药株有效。屠呦呦从古籍中获得提取灵感，相关发现获 2015 年诺贝尔奖，是中医药现代化的范例。
Artemisinin comes from sweet wormwood and, inside the parasite-laden red cell, generates reactive oxygen species that damage parasite proteins, killing rapidly and working against resistant strains. Tu Youyou drew extraction insight from ancient texts; the work won the 2015 Nobel Prize.

病毒是怎样进入人体细胞的？
How does a virus get into a human cell?
病毒表面的附着蛋白必须先与宿主细胞膜上的特定受体结合，就像钥匙配锁：新冠病毒的刺突蛋白结合ACE2，HIV结合CD4和CCR5，流感病毒结合细胞表面的唾液酸。结合后病毒或直接与细胞膜融合，或被细胞“吞入”囊泡再释放遗传物质。受体在不同组织的分布决定了病毒的组织偏好和症状，这也是为什么阻断受体结合成为抗病毒药和疫苗设计的核心靶点。
A virus's attachment protein must first bind a specific receptor on the host cell membrane, like a key fitting a lock: the SARS-CoV-2 spike binds ACE2, HIV binds CD4 with CCR5, and influenza binds sialic acid on the cell surface. After binding, the virus either fuses directly with the membrane or is taken up in a vesicle before releasing its genetic material. Where those receptors occur in the body determines a virus's tissue preference and symptoms, which is why blocking receptor binding is a central target for antiviral drugs and vaccine design.

细菌和病毒的根本区别是什么？
What is the fundamental difference between bacteria and viruses?
细菌是完整的单细胞生物，有自身代谢和繁殖能力，可用抗生素杀灭；病毒没有独立代谢，须钻进宿主细胞借其机器复制，抗生素对其无效而需抗病毒药或疫苗。两者大小、结构和致病方式都相差很大。
Bacteria are complete single-celled organisms that metabolize and reproduce on their own and can be killed by antibiotics. Viruses lack independent metabolism and must hijack a host cell's machinery to replicate, so antibiotics do not work and we rely on antivirals or vaccines.
