抗病毒药和抗生素为什么不能互相替代?

Why can't antivirals and antibiotics substitute for each other?

抗生素针对细菌的结构和代谢,对病毒无效;抗病毒药多干扰病毒复制的特定环节,二者作用对象完全不同。
Antibiotics target bacterial structure and metabolism and don't touch viruses; antivirals block specific viral replication steps. Their targets are entirely different.

为什么抗生素不能杀病毒?

Why can't antibiotics kill viruses?

抗生素打的是细菌独立活着的机器:造肽聚糖壁、在核糖体上做蛋白,断掉任一环就没法增殖。病毒没有细胞结构,没壁也没核糖体,只能把基因组送进宿主细胞借宿主的机器复制,故没有可结合的靶点。选择性毒性靠细菌 70S 与人 80S 核糖体的差别,病毒连这类机器都没有。但要注意:并发细菌感染仍要靠抗生素,抗病毒药抑的是病毒自带的酶。
Antibiotics hit the machinery a bacterium needs to live on its own: its peptidoglycan wall, protein made on its ribosome—block either and it cannot multiply. A virus has no cell, no wall, no ribosome, no metabolism of its own; it inserts its genome into a host cell and replicates with the host's equipment, so there is nothing to bind. Selective toxicity rests on bacterial 70S ribosomes differing from human 80S ones, and a virus supplies no such machine. Secondary bacterial infection still calls for antibiotics, while antivirals inhibit the virus's own enzymes.

病毒载体疫苗是怎样工作的?

How do viral-vector vaccines work?

它把病原的关键基因装入无害的病毒“快递”,送入人体细胞表达抗原,从而训练免疫记忆,而不会引起该疾病本身。
They package a pathogen's key gene into a harmless virus 'courier' that delivers it to your cells to make the antigen and train immune memory - without causing the disease.

单克隆抗体药物为什么被称为“生物导弹”?

Why are monoclonal antibodies called 'biological missiles'?

它是在实验室制造的、能精准结合某一靶分子的抗体,像导弹一样把治疗作用送到特定目标,广泛用于自身免疫病与肿瘤。
They are lab-made antibodies that lock onto one specific target molecule, delivering therapy precisely like a missile - widely used in autoimmune disease and cancer.

靶向药物为什么比传统化疗“更准”?

Why are targeted drugs 'more precise' than traditional chemo?

靶向药识别癌细胞特有的分子(如特定突变或受体)来抑制其生长,对正常细胞损伤相对小;但通常需要先检测靶点。
Targeted drugs hit molecules unique to cancer cells (specific mutations or receptors), sparing normal cells more - but usually require testing for the target first.

为什么同一类止痛药有的要处方、有的不用?

Why are some painkillers prescription-only and others not?

取决于强度与风险:阿片类镇痛强但易成瘾,需处方;对乙酰氨基酚等用于轻痛,多可非处方购买。都应按说明使用。
It depends on strength and risk: opioids are powerful but addictive and need a prescription; paracetamol for mild pain is often over-the-counter. Both should follow instructions.

为什么普通感冒大多不吃药也会好?

Why do most colds get better without medicine?

普通感冒多由病毒引起、可自愈,药物主要缓解鼻塞流涕等症状,休息和补水更重要;滥用抗生素无效且有害。
Most colds are viral and self-limiting; medicines mainly ease symptoms while rest and fluids do the real work. Antibiotics don't help and can harm.

为什么有些药要在避光阴凉处保存?

Why must some medicines be kept cool and away from light?

光照和高温会让某些药物成分分解、失效甚至产生有害物质;按说明书储存才能保证疗效与安全。
Light and heat can break down some drug ingredients, making them ineffective or even harmful; store as labeled to keep them safe and working.

激素药膏能长期随便涂吗?

Can steroid creams be used long-term or casually?

外用激素抗炎止痒有效,但长期不当使用可致皮肤变薄、色素沉着等;应按医嘱控制部位与时长。(温和提示:用药请遵医嘱)
Topical steroids calm inflammation and itch, but long or wrong use can thin skin or cause pigmentation - follow guidance on where and how long. (Gentle note: use medicines as directed.)

减毒活疫苗和灭活疫苗有什么不同?

How do live-attenuated and inactivated vaccines differ?

减毒活疫苗用弱化但仍有活性的病原,免疫强且持久,体弱者需谨慎;灭活疫苗用杀死的病原,更安全但常需多剂加强。
Live-attenuated vaccines use weakened but alive germs - strong, lasting immunity, with caution in the frail. Inactivated vaccines use killed germs - safer but often need boosters.

为什么药水常常是苦的还要喝?

Why drink bitter medicine if it tastes bad?

因为药水里装着帮身体打败病菌、让肚子不痛的小助手,虽然苦一点,却能让我们快点好起来。
The medicine holds little helpers that fight germs and stop tummy aches; bitter though it is, it helps you get better faster.
