Feng Haiqing took a sip of tea from the teacup, and after putting down the teacup, he asked slowly: "Doctor Yu, how much do you know about tumor fluorescent staining imaging?" ”

Tumor fluorescence staining is a new type of tumor detection technology, which uses the specific binding of fluorescent dyes to tumor cells, so that tumor cells can show obvious fluorescent signals under the microscope and corresponding imaging equipment.

This technique can be applied during 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 surgeries, Yu Zhiming, as a diagnostician, has a general understanding of this technology.

He replied matter-of-factly: "I know a little bit about it." ”

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

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

Yu Zhiming knows that this fluorescent staining imaging technology has been applied in some tumor surgeries and has achieved good results.

However, it is currently only an adjunct to assist the surgeon in determining the boundaries of the tumor.

The scope of tumor resection is mainly determined by the surgeon in charge based on multiple data and experience.

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

The first is the highly sensitive fluorescent contrast agent that can be injected, which is able to selectively aggregate in tumor tissue.

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

Yu Zhiming bowed his head softly: "Indeed, after this technology is completed, there is no need for me to mark cancerous tissues. ”

Feng Haiqing said proudly: "Dr. Yu, the comprehensive performance of the fluorescent contrast agent and imaging equipment developed by me and my team is not inferior to the products of major foreign companies. ”

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

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 able to get relief and not have to be confined to tumor surgery."

He said with deep feelings: "Dr. Yu, your ability is unique, which can give you a transcendent status, but on the other hand, it is not a shackle. ”

"All kinds of relationships, all kinds of requests, as well as pressure from power, money, etc., when a job is necessary for you, even if you want to vomit, how reluctant, sometimes you have to do it."

Yu Zhiming thought deeply about this.

He pondered for a moment and said, "Dr. Feng, you and your research team have achieved quite a lot of results in the research of tumor fluorescence imaging technology, what can I do after joining?" ”

Feng Haiqing smiled and said, "Doctor Yu, there are more things you can do after you join." ”

"At present, this fluorescence imaging technology is only an auxiliary labeling method, and in tumor surgery, it mainly depends on the experience and judgment of the surgeon."

"One is that it will take some time for new technologies to be accepted and trusted. Second, the recognition accuracy of fluorescent contrast agents on tumor cells needs to be further improved. ”

Feng Haiqing took another sip of water from the teacup, and then said, "Doctor Yu, you have an unimaginable talent that can accurately identify cancerous tissues. ”

"We can find out the tissues that cannot be identified by fluorescent contrast agents, as well as the tissues that are wrongly identified, and do in-depth research on the causes to further improve their identification ability."

Yu Zhiming nodded lightly.

Feng Haiqing said happily: "Doctor Yu, did you agree to my invitation?" ”

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

"The most important thing is that I want to do a lot of things, but 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 very understandingly, and said: "Doctor Yu, once our tumor fluorescence imaging technology has made a major breakthrough, it will not only allow you to get more time for yourself, but also allow you to win major honors......

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

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

After sending Doctor Feng away, Yu Zhiming looked at the time, and there were still nine minutes until one o'clock at noon.

He hurried to sit in his office chair and close his eyes......

In the afternoon, it is still an employee welfare physical examination.

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

Yu Zhiming detected some foreign bodies in the 43-year-old woman's womb.

At first, he thought it was an endometrial lesion.

Upon further investigation, Yu found that the foreign bodies were too regular and had a smooth surface.

He finally determined that it was an alien ball with a diameter of 0.5 centimeters, and there were as many as seven.

Yu Zhiming informed the woman of the discovery of the investigation, but the other party's expression was not surprised, but his face turned red, thanked him in a low voice, and left in a hurry......

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

One of the men had jaundice on his face, and Yu Zhiming could tell that he had a serious liver problem without having to examine it.

Yu Zhiming examined him, and sure enough, liver cirrhosis was quite serious, and it was not far from decompensation.

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

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

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

"Doctor Yu, please tell me frankly."

Yu Zhiming said frankly: "It will take about two or three years, but in your case, you can still transplant treatment." ”

As he spoke, Yu Zhiming also glanced at his twin brother who looked quite healthy on the side.

Liver transplantation can be donated by parents, and because it is identical twins, there is no rejection immune reaction, so it can be said that it is the most suitable liver donor.

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

The twin brother snorted lightly and said, "What do you have to suffer, I will donate half of my liver to save you, and what I get back is only what should be mine." ”

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

This is a major inside story, although Yu Zhiming's gossip heart is great, but the time is tight and the task is heavy, and he doesn't have the time to listen to the twins grinding their teeth now.

Yu Zhiming looked at his twin brother and asked, "You are also here for a physical examination?" ”

"Yes, lie down."

The twin elder brother smiled at Yu Zhiming, and hurriedly lay down on the examination bed let by the younger brother.

Yu Zhiming changed into a pair of medical gloves and examined his twin brother step by step.

But after a while, Yu Zhiming's face sank, which made the twin brother's heart instantly rise to his throat.

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

With this gloomy expression, the cancer is gone.

"Yu ...... Dr. Yu, I ...... Got cancer? The twin brothers were so frightened that they couldn't speak.

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

"Lung cancer?"

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

Yu Zhiming explained: "The clinical symptoms of lung cancer are mainly related to factors such as the location of the occurrence, the size of the tumor, the type of tumor, the stage of development, whether there are complications, whether the tumor metastases, etc., usually 5%-15% of lung cancer patients have lung cancer without any uncomfortable symptoms. ”

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

However, there are still a small number of patients who have lung cancer and do not have any clinical symptoms in the early stages.

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

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

It is precisely because these lung cancer patients have no symptoms that the diagnosis of lung cancer is delayed and the treatment is affected.

This is the case with the twin brothers.

"Dr. Yu, my lung cancer should be at an early stage, right? With good treatment, it's not a big problem, right? ”

Yu Zhiming said honestly: "All of your five lung lobes have become cancerous, and there is more than one. ”

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

At this moment, the twin brother interjected and asked, "Dr. Yu, he has lung cancer, can't he donate his liver?" ”

Yu Zhiming nodded and replied: "In principle, it can't." ”

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

There are some things that should not be said by him.

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

For another example, cancer patients are not allowed to donate large organs to others, but the two of them are in special circumstances.

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

Liver transplantation is still possible.

But in any case, in the end, there is no possibility of treating these twin brothers at the same time......

At nearly 5:50 in the afternoon, Yu Zhiming finally completed the day's physical examination.

He came out of the soundproofing inspection room and found Teacher Qi Yue waiting outside.

"Zhiming, Feng Haiqing's guy is not a good partner to work with, don't promise him......"
