After being fired, I became the light of medicine

Chapter 178 Mr. Zhang, we are convinced!

"Mr. Zhang, this is Zhang Yang, the boss of Qingshan Pharmaceutical. It was they who developed this 'nano-nodule developer'."

"Mr. Zhang, this is Mr. Zhang, the most important academician of our aerospace group, and one of the important persons in charge of the national manned lunar landing project."

"When Professor Zhang heard that you had developed this 'nodule contrast agent', he immediately expressed his willingness to give it a try and to be your first clinical trial subject."

Secretary Bai acted quickly. After Mr. Zhang decided to go to Chengdu to take a CT scan and try the "nodule contrast agent", he immediately arranged the itinerary.

At ten o'clock the next morning, Mr. Zhang and his party arrived at the Third People's Hospital of Chengdu on time and met Zhang Yang.

"Zhang Yang, I am an old man. I am sorry to cause you trouble by coming here uninvited..."

Zhang Yang smiled and said:
"It's no trouble, no trouble. Thank you, Mr. Zhang, for your support for our clinical trial work!"

"How about this, Mr. Zhang? You take a rest. We will prepare here and give you a CT scan at 2 pm. What do you think?"

"Okay! Everything is up to you!"

After a few simple pleasantries, Zhang Yang finalized the arrangements for today.

After settling Mr. Zhang and his party, Director Hao and Director Qiao, who had come specially from Beijing, also arrived at the Chengdu Third People's Hospital.

In the office, President Zhou warmly welcomed the two directors.

"Director Hao, Director Qiao, two rare guests... please come in, please come in!"

"Let me introduce you two. This is Mr. Zhang Yang from Qingshan Pharmaceutical..."

Dean Zhou was very enthusiastic.

You know, Director Hao and Director Qiao are both top experts in thoracic surgery in China, and it is usually difficult to invite them all.

This uninvited visit is a great opportunity for communication.

But just as Dean Zhou was introducing Zhang Yang, suddenly, another tall and thin figure walked in from the office door.

Looking closely, it was Director Dai Jigang from Shancheng Xinqiao Hospital.

Dean Zhou couldn't help but be stunned for a moment, and the smile on his face instantly turned a little awkward.

Everyone knows that Director Hao, Director Qiao and Director Dai are all top thoracic surgeons in the country, but they made completely different judgments on the case of Mr. Zhang's lung nodules.

Perhaps the three of them had no other ideas when they made their judgment, but as Mr. Zhang's affairs have developed to this point, and now that they are gathered together, it is inevitable that everyone will have some ideas of "dealing it out" and "seeing who is more powerful."

This is human nature.

The atmosphere in the office suddenly became a little awkward, but Dean Zhou reacted immediately!
He smiled and said:
"Director Dai, you're just in time. Director Hao and Director Qiao have just arrived!"

"Don't stand at the door, come in quickly!"

Dean Zhou also greeted him warmly, and Zhang Yang took the opportunity to secretly look at Director Dai in front of him.

To be honest, he was quite interested in Director Dai!
He knew very well that Director Dai made the diagnosis only after Director Hao and Director Qiao determined that the nodule was malignant.

Other doctors might have been ambiguous long ago, but Director Dai dared to insist so firmly that it was a benign tumor after the three top authoritative doctors in the country determined it to be malignant!
Apart from anything else, this little confidence is enough to prove that Director Dai is something!

With Dean Zhou's warm greeting, Director Dai also greeted everyone with a smile, and the atmosphere was not so awkward.

Gradually, everyone's topic fell on Tsingshan Pharmaceutical's "nano-nodule developer".

Zhang Yang was also very happy to introduce his own "nano-nodule developer" to the three people.

The three directors in front of us are all the top authoritative doctors in thoracic surgery in the country. In China, the promotion of a drug is often from top to bottom.

Simply put, after being used in the best hospitals, it will gradually be popularized to slightly worse hospitals through various lectures, learning exchanges, and further studies.

If we can get the approval of the three directors in front of us, it will definitely be a good thing for the promotion and sales of "Nano-nodule Contrast Agent".

Before they knew it, they had been communicating for nearly an hour, and the three directors had a deeper understanding of "nodule contrast agent"!
Seeing that it was time for lunch, Zhang Yang stood up and interrupted with a smile:

"Three directors, it's almost time, let's have a meal together first."

"In the afternoon we will be able to see the first real application of the 'nano-nodule contrast agent'!"

Everyone stood up:

"Okay, let's wait and see."

Time passed quickly, and before long, it was already one o'clock in the afternoon.

Since the "nano-nodule developer" needs 60 minutes for the drug ingredients to reach the lung tissue and complete the fluorescent reaction,

So at one o'clock in the afternoon, Mr. Zhang came to the CT room and injected the "nano-nodule contrast agent" in advance.

As the colorless and transparent liquid was injected into the vein, Zhang Yang also appeared in the CT room.

"Mr. Zhang, how do you feel? Is there anything unusual?"

"Everything is fine, Zhang Yang, don't worry, I completely trust you!"

"it is good!"

At two o'clock in the afternoon, Mr. Zhang was ready and lay on the CT machine.

In the operating room of the CT room, Secretary Bai, Director Hao, Director Qiao, Director Dai, Zhang Yang and a CT operator were all ready, waiting for the dual-source CT machine from Elephant Medical to start the first lung nodule CT scan.

Zhang Yang glanced at the time and stopped talking. He patted the CT operator on the shoulder and said:

"It's almost time, let's get started!"

"Okay, Mr. Zhang!"

At a command, as the operator pressed the scan start button of the dual-source CT machine, the unique electric current sound of the CT machine was audible.

The operator patiently guided Mr. Zhang on how to exhale and inhale. After about a minute, the entire CT scanning process was completed.

The door of the CT room opened, and Mr. Zhang's children began to help him sit up. The atmosphere in the operating room became extremely tense. Everyone held their breath, their eyes fixed on the computer screen.

The same goes for Zhang Yang. He is also looking forward to seeing the final result!

The imaging speed of dual-source CT is very fast and can be completed in about one minute. As for why it takes four or five hours to get the results in the hospital, it is because you still need to wait for the radiologist to make a diagnosis after imaging.

The operating room in front of us obviously did not need any radiologists to make a judgment, but one minute still seemed a little long.

At this moment, Zhang Yang suddenly said:

"Director Hao, Director Qiao, and Director Dai, if I remember correctly, Mr. Zhang's previous CT scan showed a solid new nodule in the left lung and four ground-glass nodules in the right lung, for a total of five lung nodules."

"Everyone thinks there is no problem with the solid nodules in the left lung and the first three nodules in the right lung. The biggest disagreement comes from the fourth ground-glass nodule in the right lung, right?"

"Director Hao and Director Qiao, you think it is a malignant nodule, but Director Dai, you think it is a benign hyperplasia..."

Zhang Yang's words made the three of them even more nervous. Even Director Dai couldn't help but push up his glasses frame and whispered while looking at the computer screen:

"Yes, that's exactly what happened."

"um, yes!"

"Okay, the CT images will be out soon, and we'll know the results soon!"

As the words fell, everyone stared at the screen intently. Gradually, the outline of Mr. Zhang's lungs appeared, and then the image of the right lung became clear.

The first ground-glass nodule appears.

The second ground glass nodule appeared. The third, the fourth...

Before everyone could react, due to the special effect of the "nodule developer", if the nodule was benign, it would not produce any fluorescent reaction, and the image displayed on the computer screen would be grayish white, just like a normal CT image.

While everyone was looking at the gray-white image, Zhang Yang already knew that Director Dai of Shancheng Xinqiao Hospital should have made the correct judgment about the result of the fourth nodule!
If there is no fluorescent reaction, it means that the fourth nodule in the right lung is "benign hyperplasia"!
Director Dai is indeed quite capable, surpassing two of the most authoritative thoracic surgery authorities in the country!

Thinking of this, Zhang Yang smiled and looked at Director Dai:

"Director Dai, congratulations, there is no fluorescent reaction on the CT image, which means that this is a benign nodule!"

"Your judgment is correct!"

"what?!"

Director Dai was also stunned for a moment, then he reacted and a smile appeared on his face in an instant.

Zhang Yang's words obviously fell into the ears of Director Hao and Director Qiao. They were shocked. Looking at the image results that were no different from traditional CT images, they were obviously unable to react for a while.

"Mr. Zhang, this...will there be any errors in the results?"

“I didn’t see any fluorescent reaction!”

Zhang Yang shook his head. He was obviously very confident in the "nodule contrast agent" provided by the system.

However, Director Hao and Director Qiao's doubts did make some sense. Just as they were about to explain in detail, a bright red dot suddenly appeared on the computer screen!
He looked hurriedly and was suddenly stunned!

Left lung!

The location of the red dot, isn’t this the location of the solid nodule in Mr. Zhang’s left lung? !

Others immediately noticed the red dots that suddenly appeared on the CT image and were equally surprised!

The next second, without Zhang Yang’s explanation, everyone realized that this should be the fluorescent reaction that Zhang Yang mentioned!

That is to say!

The nodule that Director Hao and Director Dai had disagreed about before turned out to be fine!
Instead, it was the left lung that the three top doctors in the country had not noticed!

Is the solid nodule in the left lung a real malignant nodule? !

This is impossible!
The results of the CT images shocked everyone. At this moment, Director Dai, who was originally smiling, suddenly took a step forward and squeezed directly in front of the computer screen.

His face was solemn, and he anxiously asked the CT operator beside him:
"Teacher, could you please hide this red fluorescence reaction temporarily? I want to see the original CT image layer, okay?"

"of course can!"

The CT operator hurriedly turned off the fluorescence reaction function temporarily in the software, and the image on the computer screen was restored to the most traditional CT image!

Director Dai looked extremely serious as he began to carefully examine the latest CT images. He also took out the last CT images of Mr. Zhang for comparison.

At this moment,
Not only him, but also Director Hao and Director Qiao, who were originally immersed in disbelief and unwillingness to accept, reacted, quickly crowded in front of the computer screen, and began to carefully review the latest CT images together!

At this moment, the two no longer cared about the ground glass nodule in the right lung.

If the ground-glass nodule in the right lung is considered a "battle between superiority and inferiority" among the three people, then the "solid nodule in the left lung" that none of the three noticed is obviously a "battle between people and drugs!"

They couldn't believe that all three of them were wrong!

Director Hao, Director Qiao, and Director Dai examined it with unprecedented care. Gradually, they began to have a heated discussion while examining it.

Various professional terms and assumptions echoed in the small operating room. Zhang Yang, the operator and Secretary Bai consciously took a step back, leaving all the space in front of the screen to the three of them.

Zhang Yang was also quite touched. No one could have imagined that the three people who originally had some intention of "competing with each other" would actually start a discussion without any interruption at this moment!
After ten minutes, the discussion among the three people gradually died down. Director Dai stood up first and turned around, looking at Zhang Yang in shock:
"Mr. Zhang, we have carefully compared the CT images just now with the CT images that Mr. Zhang took three months ago!"

“I have to admit that compared to the CT images taken three months ago, this solid nodule has not grown significantly and is still 5mm, but it does have some malignant burrs and branching features inside!”

“So, we also think it’s possible that this solid nodule is malignant!”

"Your judgment on the developer should be correct!"

Zhang Yang nodded. At this moment, Director Hao turned around and said:

"This time I also agree with Dai Jigang's judgment!"

"To be honest, the 5mm nodule is too small. If it weren't for the fluorescent reaction on the CT image, we might not have noticed the change in this solid nodule this time!"

“Of course, if we waited for it to grow a little bigger, we would surely have discovered that it was a malignant nodule;
But to be honest, solid nodules are very malignant. Once they really enter the rapid development period, if we discover them a year later, the risk of spread and the risk of surgery will definitely be higher than it is now! ”

"I have to say, Mr. Zhang, the clinical effect of your drug is many times better than I imagined. It's amazing!"

Zhang Yang did not expect that Director Dai and Director Hao would suddenly give such high praise to the "Nano-nodule Contrast Agent".

He smiled, but it was not time to pop the champagne at halftime.

"Director Hao, Director Dai, we still have to look at the pathology results to make a final decision."

"Well, let's go and tell Elder Zhang now. If nothing else, this solid nodule really needs surgery immediately!"

Soon, a group of people walked out of the operating room. Mr. Zhang and his children had been waiting in the corridor for a while.

Seeing Zhang Yang and others coming out, Elder Zhang stood up and asked in person:

"Zhang Yang, what's the result? Is it benign or malignant?"

Zhang Yang exhaled lightly:

"Mr. Zhang, there is good news and bad news."

"The good news is that our 'nano-nodule developer' test results show that the fourth ground-glass nodule on your right lung did not have a fluorescent reaction. In other words, no cancer cell markers were detected. It is a benign hyperplasia!"

"Huh? What about the bad news?"

"The bad news is that the new solid nodule on your right lung is a malignant nodule. Considering that solid nodules are the most malignant, it is recommended that you must undergo surgery immediately!"

"Of course, the one on the left lung can be cured with a minimally invasive surgery, and you will be fully recovered within a week! You don't have to worry about delaying your work!"

"Do you think you would like to have the surgery now? Director Hao, Director Qiao, and Director Dai are all here. If everything goes well, the surgery can be arranged tonight."

No one could have imagined that the final outcome would be like this.

But this time, Master Zhang didn't let Zhang Yang wait too long. After just one minute, he nodded:

"Zhang Yang, I trust you. Let's do the surgery here!"

At 7 o'clock in the evening, after five hours of preparation, three top thoracic surgery experts, Director Hao, Director Qiao and Director Dai, completed a minimally invasive operation that could not be any smaller.

Of course, in addition to removing the solid nodule on Mr. Zhang’s left lung, this time, after obtaining Mr. Zhang’s consent, Director Hao personally located the fourth ground-glass nodule on the right lung and performed a “sampling biopsy.”

At 8 o'clock in the evening, the intraoperative pathology results came out.

Intraoperative pathology of ground glass nodules in the right lung: normal tissue, benign hyperplasia.

The intraoperative pathology of the left lung solid nodule was: lung adenocarcinoma, micro-invasion (stage 1).

At 9 o'clock in the evening, Director Hao, Director Qiao, and Director Dai walked out of the operating room. The first thing they said when they saw Zhang Yang was:

"Boss Zhang, we are convinced."

"The left lung is indeed lung adenocarcinoma, and the right lung is indeed benign hyperplasia, there is no doubt about it!"
