After hearing Yang Fan's words, everyone couldn't help but nodded.
Yang Fan is right. Indeed, this is an issue that deserves great attention and is also a key to measuring the value of this project.
Otherwise, even if research makes progress and they successfully cultivate viruses or bacteria specifically targeting Helicobacter pylori in the stomach, they will not be able to be put into clinical treatment, let alone marketed.
So everyone couldn't help but turn to look at Fang Renzheng, waiting for his answer.
Fang Renzheng smiled and nodded when he heard this: "Your concern is right, this is indeed an important problem we face during the entire project research process.
In this project, we actually faced many problems.
For example, when choosing a phage, there are many types of phages, from T1, T2, to T3, T4, T5, etc. We must find an ideal phage among them.
Then, targeted culture is performed to change the target of attack, from the original bacteria to Helicobacter pylori in the stomach.
This is just the first step. Then we need to stabilize the superphage we cultured against Helicobacter pylori in the stomach so that it has stable DNA.
Therefore, it is not easy to mutate during many reproduction processes, or even eliminate mutation. Even if it mutates, its mutants will not cause harm to the human body.
To put it simply, we need to cultivate a new super phage that specifically targets Helicobacter pylori in the stomach. This phage specifically targets Helicobacter pylori in the stomach.
If the Helicobacter pylori in the stomach is completely eliminated, then the Helicobacter pylori in the stomach will die quickly after losing its ability to attack its parasitic target, and will be excreted through human metabolism.
And this new type of super phage is safe enough. It will only attack Helicobacter pylori in the stomach, not other bacteria, let alone human cells and tissues.
During the process of reproduction, mutation will not occur, or it is not easy to mutate, and even if it mutates, it will not cause harm to the human body."
After hearing Fang Renzheng's introduction, everyone couldn't help but nodded, agreeing with his statement.
Seeing this, Fang Renzheng smiled slightly, and then continued: "At present, we have found a suitable phage, and after cultivating and inducing it, we successfully changed its attack target and then attacked Helicobacter pylori in the stomach.
Everyone, please take a look, this is our relevant experimental picture."
Under Fang Renzheng's guidance, everyone looked at the big screen in front of them. Relevant experimental pictures were immediately played on the big screen, some of which were electron microscope pictures, and some of which were demonstration videos.
Through the electron microscope picture, you can see that in the petri dish, a dropper dropped a drop of light blue liquid into the petri dish, and then the electron microscope magnified the magnification. I saw that some of these blue liquids were strange-looking, and even
A somewhat scary virus or bacteriophage is spreading very actively and rapidly.
These phages spread out in the petri dish and quickly attacked the Helicobacter pylori in the stomach. It was seen that these new super phages were cultivated and quickly captured the Helicobacter pylori in the stomach after contacting the Helicobacter pylori in the stomach.
The bacteria are then inserted into the bacteria with a very sharp needle.
Then after a while, the Helicobacter pylori in the stomach ruptured, and many new, smaller super phages emerged from it. These phages traveled around, looking for new Helicobacter pylori in the stomach.
Fang Renzheng showed a proud look to everyone, and then introduced with a smile: "This is the new super phage we have cultured. What you see is this new super phage attacking the electrons of Helicobacter pylori in the stomach in a petri dish.
Microscope image.
In order to facilitate viewing, we have fast-forwarded the video screen, which is not so fast under normal circumstances.
As you can see, with the passage of time, these new super phages have attacked and eliminated all Helicobacter pylori in the stomach in the entire petri dish.
In addition to gastric Helicobacter pylori, we also placed other bacteria in the culture dish, such as Escherichia coli, Lactobacillus, Bifidobacterium, Bacteroides, Peptostreptococcus, Veillonella, etc.
As you can see, most of these other bacteria are still alive. In other words, our new super phage, while attacking Helicobacter pylori in the stomach, does not attack other bacteria.
Even after all Helicobacter pylori in the stomach has been eliminated, these new super phages that multiplied in large numbers lost their attack targets and began to die rapidly without attacking other bacteria."
After hearing Fang Renzheng's introduction, everyone couldn't help but nodded, and Wu Hao and Yang Fan also smiled.
Well done. It's really amazing that you were able to achieve such excellent results in such a short period of time. Wu Hao praised.
Thank you for your compliment. Fang Renzheng smiled and thanked him, then smiled at Wu Hao and said: "Actually, this experiment is not perfect. During the monitoring process, we also discovered that new super phages attack other bacteria. It's just that
The proportion is relatively small.
In addition, we also discovered that the new super phage mutated during its reproduction process.
Therefore, for us, this is just the first step in a long journey, and we are still far away from actually launching clinical trials."
Wu Hao heard this and waved his hands with a smile: "Don't be in a hurry, don't be in a hurry, take your time, I believe you will be able to complete it, and this is already a very remarkable achievement in itself.
How's it going? Have you written the paper?"
Fang Renzheng smiled and shook his head: "I have been busy with experiments these days and have no time to write a paper."
Wu Hao heard this and shook his head with a smile: "That's not okay. I'm busy with experiments, so I can't forget to write a paper. Moreover, the paper itself is also a kind of work. This is also your academic achievement, and it should be recognized by the entire academic community.
Know.
Take the time to write it and publish it as soon as possible so that the whole world can know about our great achievements in this field."
Speaking of this, Wu Hao softened his tone and said: "And you have to understand that this kind of important results should be done sooner rather than later. If it is leaked and others publish it first, it will be very important to you, your entire project team, and the company."
loss."
I understand. I will definitely start writing the paper as soon as possible and try to publish it as soon as possible. Fang Renzheng nodded.
Hearing Fang Renzheng's words, Qin Yongchuan showed a happy smile: "That's right, I asked you to do it before, but if you didn't do it, you said it would affect the research work.
Now that Mr. Wu has told you, you must take it seriously.
This is not only about your personal gains and losses, but also about the interests of your entire team and even the entire company.
So you must take it seriously and not be careless."
