Gas therapy appears promising in treating cancer, ischemia-reperfusion injury, heart attack, and acute situations of shock. Gas therapy is also becoming a good choice in preventive medicine against dementia, reducing cancer occurrence, cardiovascular diseases, and delaying aging. On-demand gas release allows precision therapy with few risks of gas poisoning. Here, we review targeted and controlled gas therapy, gas nanogenerators for cancer bioimaging, and gas-sensitized synergistic therapy. We focus on gases with anticancer effects such as hydrogen, carbon monoxide, carbon dioxide, nitric oxide, oxygen sulfur dioxide, hydrogen sulfide, and heavy gases. We discuss the efficiency of gas therapy combined with other therapies methods such as starvation therapy, ultrasound therapy, chemotherapy, radiotherapy, and photodynamic therapy, and applications in multimodal and ultrasound imaging.

气体疗法在治疗癌症，缺血再灌注损伤，心脏病发作和休克的急性情况方面似乎很有希望。气体疗法也正成为预防痴呆症，减少癌症发生，心血管疾病和延缓衰老的预防药物的良好选择。按需释放气体允许进行精确治疗，几乎没有气体中毒的风险。在这里，我们回顾了靶向和受控的气体疗法，用于癌症生物成像的气体纳米发生器以及气体敏化的协同疗法。我们专注于具有抗癌作用的气体，例如氢气，一氧化碳，二氧化碳，一氧化氮，氧气二氧化硫，硫化氢和重气体。我们将讨论气体疗法与其他疗法方法（例如饥饿疗法，超声疗法，化学疗法，放射疗法和光动力疗法）结合的效率，
