Now, Chloe, let us give our listeners a quick taste of what we are covering today.
现在，克洛伊，让我们给听众快速预告一下我们今天将要报道的内容。
We have a packed show.
我们有一期内容丰富的节目。
First, we are talking about a revolutionary artificial intelligence design drug that might actually
首先，我们要讨论一种革命性的人工智能设计药物，它实际上可能
reverse markers of aging.
逆转衰老的标志。
Then we look at how a breakthrough pancreatic cancer treatment is showing unexpected promise against
然后我们来看看一种突破性的胰腺癌疗法如何展现出意想不到的前景，用于对抗
lung cancer.
肺癌。
After that, we'll share an incredible medical milestone, where a genetically modified pig kidney
在那之后，我们将分享一个不可思议的医学里程碑，一颗基因改造的猪肾
kept a patient alive for nine months.
让一名患者存活了九个月。
And finally, we'll close with an inspiring story of a young fitness instructor breaking barriers.
最后，我们将以一个年轻健身教练打破障碍的鼓舞人心的故事作为结尾。
What an incredible lineup.
多么不可思议的阵容啊。
I cannot wait to get into the details of that anti -aging drug.
我迫不及待想深入了解那种抗衰老药物的细节。
Shall we begin?
我们要开始了吗？
Let us jump right in.
让我们直接切入正题。
Our headline story comes from the world of biotechnology.
我们的头条新闻来自生物技术领域。
A company called InSilico Medicine has just released early clinical data suggesting that an AI
一家名为 InSilico Medicine 的公司刚刚发布了早期临床数据，表明某种 AI
-generated drug could slow down or even reverse biological aging markers in humans.
生成的药物可以延缓甚至逆转人类的生物衰老标志。
Wait, hold on.
等等，等一下。
Did you say reverse aging?
你是说逆转衰老吗？
That sounds like something straight out of a science fiction movie.
这听起来像是科幻电影里的情节。
How exactly does a drug do that?
药物究竟确切是怎样做到那一点的？
It does sound like science fiction, but the science behind it is very real.
这听起来确实像科幻小说，但其背后的科学却是非常真实的。
The drug is called RENTOSCIRTIB, and it was originally developed to treat pulmonary fibrosis, which
这种药物叫 RENTOSCIRTIB，最初研发是为了治疗肺部纤维化，这
is a serious lung disease.
是一种严重的肺部疾病。
However, during a recent Phase 2A clinical trial, researchers decided to integrate what we call
然而，在最近的 2A 期临床试验中，研究人员决定整合我们所谓的
proteomic aging clocks to monitor the patients.
蛋白质组学衰老时钟来监测患者。
Proteomic aging clocks?
蛋白质组学衰老时钟？
That sounds incredibly complex.
那听起来极其复杂。
Could you break that down for us?
你能为我们分解解释一下吗？
Of course.
当然可以。
Think of your age in two ways.
可以从两种角度来看待你的年龄。
There's your chronological age, which is simply the number of birthdays you have celebrated.
一种是你的实足年龄，这仅仅是你过过的生日次数。
Then there is your biological age, which reflects how old your cells and organs actually are.
另一种是你的生物学年龄，它反映了你的细胞和器官实际有多老。
Proteomic clocks look at specific patterns of proteins in your blood to calculate this biological age.
蛋白质组时钟通过查看血液中特定蛋白质的模式来计算这个生物学年龄。
Ah, I see.
啊，我明白了。
So while my driver's license says I'm 30, my proteomic clock might say my body is functioning like a
所以，虽然我的驾照上写着我 30 岁，但我的蛋白质组时钟可能会显示我的身体运转得像一个...
25 -year -old, or perhaps a 35 -year -old, depending on my lifestyle. Exactly.
可能是25岁，也可能是35岁，这取决于我的生活方式。一点没错。
It's like an internal wear and tear meter.
这就像是一个内部的磨损损耗计量仪。
What the researchers discovered was that patients treated with this AI -designed drug actually showed
研究人员发现，接受这种人工智能设计药物治疗的患者实际上表现出了
a significant reduction in their biological age markers.
其生物学年龄标志物有了显著的降低。
In other words, their protein patterns shifted back to a younger state.
换句话说，他们的蛋白质模式转变回了更年轻的状态。
That is absolutely mind -blowing.
那绝对是令人惊叹的。
It's like turning back the internal odometer of a car.
这就像调慢了一辆车内部的里程表。
But why would a lung disease drug have this effect?
但为什么一种肺部疾病药物会有这种效果呢？
It comes down to a concept called geroprotection.
归根结底是一个被称为抗衰老保护的概念。
Many age -related diseases, like fibrosis, share the same underlying biological pathways as general aging.
许多与年龄相关的疾病，如纤维化，都与普通衰老拥有相同的潜在生物通路。
By targeting the cellular damage that causes the lung disease, the drug also ended up addressing
通过针对导致肺部疾病的细胞损伤，该药物最终也解决了
some of the core drivers of aging itself.
衰老本身的一些核心驱动因素。
It's like fixing the foundation of a house, which automatically repairs the cracked walls upstairs.
这就像修好了房屋的地基，楼上开裂的墙壁就会自动修复一样。
That's an excellent metaphor, Chloe.
这是一个绝妙的比喻，克洛伊。
While we still need larger trials to confirm if this translates to a longer, healthier life, it
虽然我们仍需要更大规模的试验来确认这是否能转化为更长寿、更健康的生活，但它
represents a massive leap forward for AI -driven medicine.
代表了人工智能驱动医学的巨大飞跃。
I have to agree.
我非常同意。
If AI can help us find these hidden connections between different diseases, the future of medicine
如果人工智能能帮助我们找出不同疾病之间这些隐藏的联系，医学的未来
is going to look completely different.
将会变得完全不同。
It certainly is.
确实如此。
And speaking of medical connections, our next story highlights a remarkable double -duty performance
说到医学上的联系，我们的下一个报道凸显了一项非凡的一石二鸟之举
by a newly approved cancer drug.
源自一种新批准的抗癌药物。
Scientists have discovered that a landmark drug designed for pancreatic cancer also shows great
科学家们发现，一种针对胰腺癌设计的划时代药物也展现出了巨大的
potential in fighting lung cancer.
在对抗肺癌方面的潜力。
This is fantastic news.
这真是太棒的消息了。
Pancreatic cancer is known for being extremely difficult to treat, so any progress there is already
众所周知胰腺癌极其难治，因此那里的任何进展都已经是
a major victory.
一个重大胜利。
But how does it help with lung cancer?
但它对肺癌有什么帮助呢？
It all comes down to genetic mutations.
这一切都要归结于基因突变。
Both of these cancers are often driven by a specific mutated gene called KRAS.
这两种癌症通常都由一种名为 KRAS 的特定突变基因驱动。
This gene acts like a broken light switch that's stuck in the on position, constantly telling cancer
这个基因就像一个卡在开关位置的损坏开关，不断告诉癌症
cells to multiply and grow.
细胞去增殖和生长。
So the drug acts like someone finally reaching in and flipping that broken switch off? Precisely.
所以这种药物就像终于有人伸手关掉了那个坏掉的开关？正是。
The drug, developed by Revolution Medicines, was designed to target this specific KRAS mutation in
由 Revolution Medicines 开发的这种药物，旨在针对这种特定的 KRAS 突变
pancreatic cancer.
胰腺癌。
But because the exact same genetic mutation drives a significant percentage of lung cancers,
但因为完全相同的基因突变驱动了相当大比例的肺癌，
researchers tested it there too.
研究人员也在那里进行了测试。
And the early results are highly encouraging.
早期结果非常令人鼓舞。
That makes so much sense.
这太有道理了。
It is like discovering that a key designed for one high -security lock also happens to open another
这就像发现一把为某个高安全级别锁设计的钥匙，碰巧也能打开另一个
highly secure door because they share the same lock mechanism. Exactly.
高度安全的门，因为它们拥有相同的锁机制。确实如此。
And this is highly beneficial for patients because clinical development can move much faster.
这对患者非常有益，因为临床研发进展可以快得多。
Since the drug's safety profile is already being established for pancreatic cancer, adapting it for
由于该药物的安全性特征已经在胰腺癌中得到证实，将其改用于
lung cancer patients could save years of research.
肺癌患者身上可以节省多年的研究时间。
It really highlights how modern cancer treatment is shifting.
这确实凸显了现代癌症治疗方式正在发生改变。
We are moving away from treating cancer based on where it is in the body and instead targeting the
我们正在摆脱根据癌症在体内的位置来进行治疗的做法，而是转向针对
specific genetic errors that cause it. Absolutely.
导致癌症的特定基因缺陷。绝对如此。
It is a transition toward truly personalized medicine, giving patients therapies tailored to their
这是向真正个性化医疗的转变，为患者提供量身定制的
tumor's unique genetic profile.
肿瘤独特的基因特征疗法。
That is a massive game -changer.
那绝对是一个巨大的变革因素。
It offers so much hope to those who are fighting these challenging diagnoses.
它为那些正与这些棘手的诊断作斗争的人带来了巨大希望。
Now, let us turn to another incredible breakthrough, this time in the field of organ transplantation.
现在，让我们转到另一个令人难以置信的突破，这次是在器官移植领域。
A patient was successfully kept alive for 271 days using a genetically modified pig kidney.
一名患者使用基因改造的猪肾成功存活了 271 天。
Almost nine months.
将近九个月。
That is an incredible amount of time.
那是一段难以置信的漫长时间。
I thought the human immune system would immediately reject an organ from a different species.
我以为人体免疫系统会立即排斥来自不同物种的器官。
It usually does, and that has been the biggest obstacle in this field, which is called xenotransplantation.
通常确实会排斥，这也是该领域最大的障碍，该领域被称为异种移植。
To overcome this, scientists used advanced gene editing technology to modify the pig's DNA.
为了克服这一点，科学家利用先进的基因编辑技术来修改猪的 DNA。
They removed genes that trigger human immune attacks and added human genes to make the organ more compatible.
他们剔除了引发人体免疫攻击的基因，并添加了人类基因，以使该器官更具兼容性。
That is brilliant.
这太绝妙了。
It is like putting a local uniform on a foreign visitor so the body's security guards don't
这就像给外国访客穿上本地制服，这样体内的安保人员就不会
recognize them as an intruder and let them pass through.
将其识别为入侵者并予以放行。
That is exactly how it works.
事情正是这样运作的。
The patient was kept stable and healthy for nearly nine months, which gave doctors enough time to
患者在近九个月内保持稳定和健康，这给医生争取到了足够的时间来
eventually find a compatible human kidney for a permanent transplant.
最终找到匹配的人类肾脏进行永久性移植。
So this pig kidney served as a temporary bridge.
所以这个猪肾充当了一个临时的桥梁。
That is a lifesaver, considering how long the waiting lists are for organ donations. Absolutely.
考虑到器官捐献的等待名单有多长，这简直是救星。确实如此。
In many countries, patients have to wait years for a matching human kidney.
在许多国家，患者不得不等待数年才能等到匹配的人体肾脏。
And sadly, many of them pass away before a donor is found.
可悲的是，许多人在找到捐献者之前就离世了。
By genetically engineering these animal organs, we might soon be able to offer a temporary solution
通过对这些动物器官进行基因工程改造，我们可能很快就能提供临时解决方案
that keeps patients stable and out of danger while they wait for a human match.
使患者在等待人类匹配器官的同时保持稳定并脱离危险。
It really shows how far genetic engineering and surgical techniques have come.
这充分展示了基因工程和外科技术取得的巨大进步。
It's not just about extending life.
这不仅仅关乎延长寿命。
It's about giving these families their precious time back.
而是把宝贵的时光重新还给这些家庭。
It really does.
它确实如此。
And speaking of hope and inspiration, let us move to our final story of the day.
说到希望和灵感，让我们来看看今天的最后一个故事。
A 22 -year -old man with Down syndrome has officially become a certified fitness instructor and
一名患有唐氏综合征的 22 岁男子已正式成为一名获得认证的健身教练，并且
recently led a class of 60 people at his local gym.
最近在他当地的健身房带领了一个 60 人的班级。
Oh, I love this story.
哦，我喜欢这个故事。
Becoming a certified fitness instructor is no easy task.
成为一名认证健身教练可不是一项简单的任务。
You have to pass rigorous physical and theoretical exams. Indeed.
你必须通过严格的体能和理论考试。确实如此。
It requires immense dedication, study, and physical stamina.
这需要巨大的投入、学习和良好的身体耐力。
He worked incredibly hard to overcome the challenges associated with his condition, proving that
他无比努力地克服与自身状况相关的挑战，证明了
passion and hard work can shatter any limitation.
热情和努力可以打破任何限制。
And leading a class of 60 people?
而且带领一个 60 人的班级？
That takes serious confidence and leadership skills.
这需要极大的自信和领导能力。
I think some professional public speakers would get nervous in front of a crowd that size. Absolutely.
我想一些专业的演说家在面对这种规模的群体时也会感到紧张。确实如此。
The gym members reported that his energy was incredibly infectious.
健身房成员表示，他的活力极具感染力。
He had everyone laughing, sweating, and pushing their limits.
他让每个人都在笑声中出汗并不断突破极限。
It has brought the entire community closer together.
这让整个社区紧密地联系在一起。
This is a perfect reminder that fitness and health are for absolutely everyone.
这是一个完美的提醒：健身和健康绝对适用于每个人。
Sometimes the best motivation doesn't come from high -tech gadgets, but from the raw passion of a
有时最好的动力并非来自高科技小工具，而是来自
great coach.
一位伟大教练的纯粹热情。
