Chapter 764 Don't Promise Him

Feng Haiqing picked up the teacup and took a sip of tea. After putting down the teacup, he asked slowly, "Doctor Yu, how much do you know about fluorescent staining and imaging of tumors?"

Tumor fluorescent staining is a new type of tumor detection technology. It uses the specific combination of fluorescent dyes and tumor cells to make tumor cells show obvious fluorescent signals under a microscope and corresponding imaging equipment.

This technology can be applied in surgery to help doctors remove tumor tissue more accurately through color development, reducing surgical risks and incomplete resection.

Because this new technology is mainly used in tumor detection and some tumor resection operations, as a diagnostician, Yu Zhiming's understanding of this technology is so-so.

Seeking truth from facts, he replied: "Know a thing or two."

Feng Haiqing smiled lightly and said, "Doctor Yu, fluorescent dye imaging technology is the direction of development of tumor surgery."

"Imagine if tumor cells can have their own fluorescence, or can emit light, doctors can more accurately locate tumor lesions, positive lymph nodes, and satellite metastases, and achieve complete resection of solid tumors."

Yu Zhiming knew that this fluorescent dyeing imaging technique had already been applied in some tumor surgeries, and achieved good results.

However, it is currently only an auxiliary means to assist the surgeon to determine the boundaries of the tumor.

The extent of tumor resection is mainly determined subjectively by the chief surgeon based on multiple data and experience.

In order to achieve the ideal application state mentioned by Dr. Feng, at least two further innovations are needed.

The first is a highly sensitive fluorescent contrast agent that can be injected, which can selectively accumulate in tumor tissue.

The second is a highly sensitive imaging system, which can accurately detect and quantify the content and location of contrast agents in tumor tissues.

Yu Zhiming nodded softly and said, "Indeed, after this technology is fully developed, I don't need to mark cancerous tissue."

Feng Haiqing said proudly: "Dr. Yu, the comprehensive performance of the fluorescent contrast agent and imaging equipment developed by my team and I is no less than that of the products of several major foreign companies."

"Of course, as a new technology, we still need further research to further improve product performance."

Feng Haiqing looked at Yu Zhiming and said, "Doctor Yu, I would like to invite you to join my research team to study this tumor fluorescence imaging technology together."

"Once there is a qualitative breakthrough in this technology, Dr. Yu, you will be freed from the constraints of tumor surgery."

He said with deep emotion: "Doctor Yu, your ability is unique, which can give you a transcendent status, but on the other hand, it might as well be a kind of shackle."

"All kinds of human relationships, all kinds of requests, and pressure from power, money, etc., when a job is absolutely necessary for you, even if you want to do it, no matter how reluctant you are, sometimes you have to do it. "

Yu Zhiming took this seriously.

He pondered for a moment, and said, "Doctor Feng, you and your research team have already achieved a lot in the research on tumor fluorescence imaging technology. What can I do after joining?"

Feng Haiqing laughed and said, "Doctor Yu, there are so many things you can do after joining."

"The current fluorescence imaging technology is only an auxiliary labeling method. In tumor surgery, it mainly relies on the experience and judgment of the surgeon."

"One is that it takes some time for the new technology to be accepted and trusted. The other is that the recognition accuracy of fluorescent contrast agents for tumor cells needs to be further improved."

Feng Haiqing took another sip of water from the teacup, and then said, "Doctor Yu, you have a talent beyond imagination, and you can accurately identify cancerous tissues."

"Through comparison, we can find out the tissues that cannot be recognized by the fluorescent contrast agent, as well as the wrongly recognized tissues, and conduct in-depth cause research to further improve its recognition ability."

Yu Zhiming nodded slightly.

Feng Haiqing said happily, "Doctor Yu, are you agreeing to my invitation?"

Yu Zhiming quickly explained: "Doctor Feng, this is not a trivial matter, I need to think about it seriously."

"The most important point is that there are many things I want to do, but my time is very limited, and I may not be able to find free time in the future."

"I need to do some weighing and trade-offs."

Feng Haiqing nodded understandingly, and said again: "Doctor Yu, once we achieve a major breakthrough in this tumor fluorescence imaging technology, not only will it allow you to have more time for yourself, but it will also allow you to obtain great honors..."

He deliberately paused before continuing: "This is a research achievement that is enough to win the National Science and Technology Award."

Yu Zhiming smiled and said, "This is indeed a very exciting research project..."

After seeing off Doctor Feng, Yu Zhiming looked at the time, and found that there were still 9 minutes until one noon.

He seized the time to sit on the office chair and close his eyes to rest...

In the afternoon, it is still the employee welfare medical examination.

Not long after the physical examination, Yu Zhiming found a woman who surprised him.

Yu Zhiming detected some foreign objects in the 43-year-old woman's uterus.

At first he thought it was an endometrial lesion.

After further investigation, Yu Zhiming found that these foreign bodies were too regular and smooth.

He finally determined that they were foreign spheres with a diameter of [-] centimeters, and there were as many as seven of them.

Yu Zhiming informed the woman of the investigation findings, but the woman didn't show any surprise on her face, she just blushed, thanked her in a low voice, and left in a hurry...

At nearly five o'clock in the afternoon, Yu Zhiming's examination room ushered in a pair of male twins in their 40s.

One of the men had jaundice on his face, and Yu Zhiming could tell that there was a serious problem with his liver without an examination.

As soon as Yu Zhiming checked him, as expected, he had liver cirrhosis, and it was quite serious, and he was not far from the decompensation stage.

After Yu Zhiming finished the examination, he withdrew his hand, and the twin brother lying on the hospital bed asked directly: "Doctor Yu, is there any cancer in my liver?"

Yu Zhiming shook his head and said, "I haven't found it yet."

The twin brother breathed a sigh of relief, and asked again: "Doctor Yu, how long can I live in this situation?"

"Doctor Yu, please tell me frankly."

Yu Zhiming said frankly: "About two or three years, but in your case, you can still be treated with transplantation."

While talking, Yu Zhiming also glanced at the twin brother who looked quite healthy.

Liver transplantation can be donated by one's own body, and because they are identical twins and have no rejection immune reaction, they can be said to be the most suitable liver donors.

The twin brother looked at his elder brother, sighed, and said with a painful face, "Brother, I agree to your terms."

The twin brother snorted softly and said, "What is there for you to suffer? I will donate half of your liver to save you. What I get back is what should belong to me."

"I didn't ask you to pay extra compensation."

This is an important inside story. Although Yu Zhiming is eager to gossip, but the time is tight and the task is heavy, he has no time to listen to the twins grinding their teeth.

Yu Zhiming looked at his twin brother and asked, "Are you also here for a medical examination?"

"Yes, lie down now."

The twin brother smiled at Yu Zhiming, and quickly lay down on the examination bed that his brother let out.

Yu Zhiming put on a pair of medical gloves, and checked the twin brother step by step.

But after a while, Yu Zhiming's face darkened, causing the twin brother's heart to rise to his throat in an instant.

He knew that Yu Zhiming was not good at hiding his expression, and he could tell the severity of his condition from the changes in his face.

With such a gloomy expression, the cancer is gone.

"Yu...Doctor Yu, I...have cancer?" The twin brothers were so frightened that they couldn't speak fluently.

Yu Zhiming nodded slightly and said: "Lung cancer, in order to avoid misdiagnosis, you still need to go to the oncology department for further examination."

"Lung cancer?"

The twin brother didn't believe it, and questioned: "Doctor Yu, I didn't cough, I didn't cough up blood, I didn't feel uncomfortable breathing, my lungs hurt, why did I have lung cancer?"

Yu Zhiming explained: "The clinical symptoms of lung cancer are mainly related to factors such as the site of occurrence, tumor size, tumor type, development stage, whether there are complications, and whether tumor metastasis occurs. Usually, 5%-15% of lung cancer patients develop lung cancer, and No symptoms of any discomfort."

Most lung cancer patients will have typical clinical symptoms, such as cough, hemoptysis, chest tightness, shortness of breath, weight loss, fever, dyspnea, chest pain, hoarseness, etc.

However, there are still a small number of patients suffering from lung cancer without any clinical symptoms in the early stage.

The reason why these lung cancer patients do not produce clinical symptoms is that the lesions usually grow on the edge of the lungs and do not cause erosion and damage to structures such as hilar blood vessels, nerves, and main bronchi.

At the same time, the lung cancer lesions were relatively small, and no serious complications such as secondary lung infection or metastasis occurred.

These lung cancer patients are also asymptomatic, which leads to delays in the diagnosis of lung cancer and affects treatment.

This is the case for the twin brothers.

"Doctor Yu, my lung cancer should be in the early stage, right? Treat it well, it won't be a big problem, right?"

Yu Zhiming said truthfully, "Your five lung lobes are all cancerous, not just one."

"Once you have symptoms, your condition can take a turn for the worse and the prognosis is not very good."

At this moment, the twin brother interrupted and asked, "Doctor Yu, he has lung cancer, so he can't donate his liver?"

Yu Zhiming nodded and replied, "In principle, it's impossible."

He looked at the twin brother who had become distraught at the same time, opened his mouth, and closed it again.

Some words should not be said by him.

For example, a brother with severe liver cirrhosis may consider donating his lungs to his brother.

Another example is that cancer patients cannot donate large organs to others in principle, but the two of them have special circumstances.

They are identical twins, the elder brother's lung cancer has not metastasized, and the younger brother's condition is very bad.

Liver transplantation is still possible.

But no matter what, in the final result, there is no possibility for the twin brothers to be treated at the same time...

At nearly [-]:[-] in the afternoon, Yu Zhiming finally completed his one-day physical examination.

He went out of the soundproof inspection room and found Teacher Qi Yue waiting outside.

"To Ming, that guy Feng Haiqing is not a good partner, don't agree to him..."
