After being fired, I became the light of medicine

Chapter 169 Feng Gang: I got stabbed in vain!

The impact of the "Strong Oral Liquid" is still fermenting on the Internet, but Zhang Yang has gradually withdrawn from the whirlpool of public opinion.

A few days later, he learned from Dean Zhou that Director Feng Gang had completed the lung nodule surgery.

After thinking about it, the next afternoon, Zhang Yang bought some fruits and flowers and went to the hospital to visit Feng Gang who had just undergone surgery.

Respiratory Medicine Inpatient Department, Chengdu Third People's Hospital.

As a hospital employee and also a middle-level leader of the hospital, Feng Gang was arranged to stay in a double room with relatively good conditions, and he was taken care of by his wife, Sister Xu.

"Sister-in-law, thank you for your hard work. I don't know what Director Feng can eat after the operation, so I just bought some fruits."

As soon as he entered the door, Zhang Yang handed the fruit in his hand to Feng Gang's wife, Sister Xu.

"Mr. Zhang, you are so kind. We are very grateful that you came to see Feng Gang!"

"Sit down, please sit down."

Sister Xu warmly invited Zhang Yang to sit down, and Feng Gang, who was lying on the hospital bed beside her, was also quite moved.

"Zhang Yang, it's just a minor operation, there's no need to make such a big deal... I'll be discharged from the hospital in two days!"

Zhang Yang smiled and said nothing.

What Feng Gang said is true. Medicine is becoming more and more advanced now. Ten years ago, a lung nodule surgery required a thoracotomy.

However, now most lung nodule surgeries only require finding the location of the lung nodules through CT-guided positioning, three-dimensional virtual positioning and other methods before the operation, and then using minimally invasive surgery.

Apart from anything else, at least the patient's trauma is much less, and generally he or she can be discharged from the hospital in three to five days if there are no complications.

"It's okay, Director. I have nothing to do this afternoon... so I came to see you."

"Well, thank you Zhang Yang."

The two chatted for a while, and gradually the topic shifted to Feng Gang's ground glass nodules.

"By the way, Director, have your pathology results come out? Has it been finally confirmed to be carcinoma in situ?"

It would have been fine if he hadn't said this. Upon hearing this, Feng Gang's expression suddenly changed slightly, and a hint of helplessness flashed in his eyes:
"The major pathology results haven't come out yet, but..."

"The pathological examination during the operation showed that my ground glass nodules were not carcinoma in situ, but benign hyperplasia."

"what?!"

Zhang Yang was also stunned.

During tumor surgery, doctors will immediately send the "lung nodules" and other suspected tumor tissues removed during the operation to the laboratory for "slice testing".
The purpose is to quickly know the type of tumor and the stage of cancer it has reached, so that the surgeon can promptly determine whether to expand the scope of surgical resection.

of course,

Due to the extremely tight timeline, intraoperative pathology may not be able to fully evaluate the “tumor tissue” and can only determine an approximate estimate;
So in addition to intraoperative pathology testing, there is also the most accurate gross pathology.

The results of major pathology are generally available 5-7 days after surgery, and this result is the absolute gold standard.

but……

Intraoperative pathology testing for Feng Gang's case showed benign hyperplasia, and 99% of the major pathologies are also benign!

Thinking of this, Zhang Yang was shocked!
If the lung nodule is a benign hyperplasia, then Director Feng doesn’t need to perform surgery at all!
That is to say...

Feng Gangbai was stabbed!

"Director Feng, how could such a mistake happen? Didn't you see a doctor before the operation? How come it turned out to be a benign hyperplasia?"

Feng Gang couldn't help but sigh:
"Not only did I see a doctor, I also specifically went to see Director Liu and Deputy Director Zhang of the respiratory department of our hospital."

"Do you remember that my surgery was postponed for a few days? It was because the two directors disagreed. Director Liu thought it was carcinoma in situ, while Deputy Director Zhang thought it might be benign hyperplasia. I considered it for several days and decided to have the surgery!"

"After all, my ground-glass nodule was already 8mm at the time. If I didn't take care of it, it would have likely developed from carcinoma in situ to 'micro-invasive adenocarcinoma', which would have been troublesome."

"But I didn't expect that it turned out to be a benign hyperplasia."

Zhang Yang didn't expect that there was such a story behind Feng Gang's surgery, but he soon felt a sense of déjà vu.

When Ren Xiaomin was asked to screen Qingshan Pharmaceutical employees for lung nodules, didn’t there appear to be such disagreements in the cases of several colleagues?

It seems that the judgment of whether lung nodules are benign or malignant is really misdiagnosed a lot, just as Ren Xiaomin said at the beginning.

Zhang Yang couldn't help but feel a little helpless about Feng Gang's situation, but he could also fully understand Feng Gang's choice.

Lung cancer pathology is roughly divided into three stages:

Stage 1 carcinoma in situ.

Simply put, a malignant tumor suddenly grows in the lung tissue, but at this time the tumor is still very small and has not yet broken through the basement membrane and entered the lung tissue.

The solution is also very simple. All you need to do is surgically remove the tissue around the lung nodules, and the treatment can achieve 100% cure.

This is early stage lung cancer, stage 0.

The second stage is: minimally invasive adenocarcinoma.

The literal meaning is "micro-infiltration". At this time, the cancer cells have broken through the basement membrane and entered the lung tissue, but the range of spread is not large, only within a few mm of tissue around the malignant tumor.

Compared with carcinoma in situ, microinvasive adenocarcinoma requires the removal of more lung tissue, but this still belongs to early lung cancer, stage 1 or 2.

Stage 3 is invasive adenocarcinoma.

As the name suggests, it has begun to invade the lung tissue, and the invasion is accompanied by lymph node metastasis.
At this stage, the prognosis is relatively poor. Surgical resection can no longer cure the disease. As the cancer cells metastasize, chemotherapy, radiotherapy, targeted drugs and other methods must be used to prolong life.

Therefore, the earlier lung cancer is discovered and the more attention it is paid, the less threatening it is.

At this moment, Feng Gang interrupted Zhang Yang's thoughts and continued:
"This guy, when I was worried that it was carcinoma in situ, I kept thinking about having it removed quickly to prevent it from metastasizing."

"But now after the surgery, I found out it was a benign hyperplasia and I regret it now. Zhang Yang, you don't know that this time my lung nodule is very deep in the lower lobe of my left lung, so I must have removed a lot of lung tissue."

"Lung tissue cannot regenerate. Cutting off some of it will inevitably affect lung function. Now I am starting to worry about my lung function again..."

"Many people don't know this, but I know very well that the surgery may cause coughing, chest tightness, shortness of breath and other symptoms. You may even have to gasp for air after walking up the stairs."

At this point, Feng Gang suddenly coughed several times and couldn't help but sigh:

"Hey, Zhang Yang, do you still remember what I said to you before?"

"At first I suggested that you develop a targeted drug to treat lung nodules. Now it seems that it would be better to develop a drug that can identify whether lung nodules are benign or malignant. This will reduce many unnecessary surgeries!"

Zhang Yang couldn't help but let out a bitter smile. Ren Xiaomin seemed to have mentioned this request once before, but it was not that simple!
But he still comforted her:

"Okay, okay, Director, your suggestion is very good. I'll take note of it and discuss the feasibility with the R&D team when I get back to the company."

Of course, Feng Gang was not naive enough to think that the matter was settled. The two continued to discuss work matters for a while. After about fifteen minutes, Zhang Yang felt that the time was about up, so he stood up and said goodbye and left.

Feng Gang's wife, Sister Xu, personally sent Zhang Yang downstairs. When they set out on the journey back to the company, Zhang Yang began to think about the suggestion Feng Gang had just mentioned while driving.

First of all, from a commercial perspective, the market prospects for developing a drug that can identify whether lung nodules are benign or malignant are bound to be broad.

Apart from anything else, who the hell wants to get stabbed without any assurance?

Just like Feng Gang's case, if it could be diagnosed as benign hyperplasia before the operation, there would be no need for surgery at all. Not only would the patient lose money, but he would also lose people.

"But how can we distinguish whether a lung nodule is benign or malignant?"

"Take medicine?"

"Drugs can find ways to quickly reach lung tissue, and malignant tumors also have some 'tumor markers' that are different from benign tumors. But even if the drugs recognize these 'tumor markers', how should they show it?"

"Moreover, many patients have more than one lung nodule. How can we clearly judge whether one or several lung nodules are benign and the others are malignant?"

"That is to say, the 'tumor marker' approach does not work and cannot accurately determine which lung nodules are problematic!"

Zhang Yang was thinking while driving, but the more he thought about it, the more he felt that this problem could not be solved by a single drug.

In other words, there is no way to solve this problem with current medical technology!
Twenty minutes later, he returned to Qingshan Pharmaceutical and immediately called Wei Tian and a group of technical backbones to hold a meeting to discuss the feasibility of this matter.

After some discussion, everyone had basically the same opinion that with the current development of medicine, it is almost impossible to rely on a single drug to distinguish between benign and malignant lung nodules.

In desperation, Zhang Yang had to give up this idea temporarily.

In the next few days, he shifted the focus of his work back to the clinical trials of "Strong Sperm Oral Liquid".

Thanks to the influence of the proposal, the clinical trial of "Strong Sperm Oral Liquid" went smoothly, and some people in the group even started queuing up for a place in the Phase III clinical trial.

Zhang Yang finally felt relieved.

As the weekend was approaching, he even made a rare appointment with his younger sister last week to watch a movie and have hotpot together. When he returned home with a bloated heart, he suddenly heard an exciting voice coming from his mind.

"Dear host, the new simulation plot node has been activated, please enter the simulator as soon as possible to check!"

Zhang Yang's eyes lit up and he quickly entered the simulator!
You know, the simulation story mode in the simulator has not been activated for more than a year!

The most important thing is that although the simulator has been updated to version 2.0 and is more powerful, all functions of version 2.0 require energy values!

In the story mode, you can not only get the top drug patents provided by the system for free, but also earn a lot of energy points!
I excitedly entered the simulator and called out the light blue screen, which displayed a striking task prompt:

[Currently simulatable nodes: Phase 1 - Biological Laboratory. ]

As a veteran who had experienced many simulated plots, Zhang Yang did not hesitate at all and went straight into the simulated plot!

【Start simulation! 】

After a period of darkness, the scene gradually became brighter. With the experience of several previous simulations, Zhang Yang did not move at the first moment. Instead, he looked around to determine where he was.

Soon, he was somewhat surprised by the familiar scene before him.

Several experimenters in white lab coats were busy with various test tubes and reagents at the operating table, while two other people were recording on the computer.

Familiar white lab coats, familiar biological operating tables, familiar test tubes and instruments!

here it is!
A biological laboratory!

And myself...

Seems to be a biological researcher?

"Could it be that the model this time is to develop a drug as a biological researcher?"

Zhang Yang's mind suddenly opened up, but his several simulation experiences made him not rush to confirm. He continued to observe the situation in the laboratory and soon noticed some differences.

Just like in the previous copy of "The Fate of a Generation", there were about four or five people in the biological laboratory, and all of these experimenters were foreigners!
“Is this a foreign biological laboratory?”

Two huge questions emerged in Zhang Yang's mind. What he needed to do now was to first confirm his identity and where this place was!

After looking around, he walked up to the nearest white experimenter who was taking notes.

"Hi, man, I have amnesia, where is this place? What time is it? What are we doing?!"

The white experimenter was stunned for a moment, then turned around and gave Zhang Yang a blank look.

“Mr Zhang, I know you are usually very humorous, but I don’t think this is funny at all;
Don't think you don't have to work just because you pretend to have amnesia. Let me tell you, if you don't finish your work today, you will definitely be kept here."

Zhang Yang knew that this was a simulated plot, and he was too lazy to talk any more. He suddenly grabbed the collar of the white man in front of him and said fiercely:

"Fuck, I'm not kidding you! Tell me what time it is, where this is, and what we are doing!"

"Fuck, what the hell!"

Zhang Yang's loud voice attracted the attention of several experimenters present, and the white man who was caught couldn't help but swear.

However, under Zhang Yang's strong coercion, he quickly replied:

"Zhang, I think you are not losing your memory, you are crazy!"

"Today is August 2018, 8. We are here at the Adrev Biological Laboratory in Norway. We are all Dr. Eric's assistants!"

"We are currently analyzing data on small cell lung cancer in lung cancer!"

"You are responsible for collecting and summarizing disease data for the Nordic population, and I am responsible for collecting and summarizing disease data for the Asian population!"

"Do you still have any questions?"

Are data on the prevalence of small cell lung cancer by ethnicity collected?

Zhang Yang was slightly stunned. There was indeed this kind of collection work in the biological laboratory.

After a moment, he let go of the white experimenter and a smile appeared on his face.

"Okay, last question. What's your name?"

"Evans."
