Feng Haiqing picked up the teacup and took a sip of tea. After putting down the teacup, he slowly asked: "Doctor Yu, how much do you know about fluorescent staining imaging of tumors?"
Tumor fluorescent staining is a new type of tumor detection technology that uses the specific combination of fluorescent dyes with tumor cells to cause the tumor cells to show obvious fluorescent signals under a microscope and corresponding imaging equipment.
This technology can be applied during surgery to help doctors more accurately remove tumor tissue 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, a diagnostician, has only an average understanding of this technology.
He replied matter-of-factly: "I know a little bit."
Feng Haiqing smiled softly and said, "Dr. Yu, fluorescent dye imaging technology is the development direction of oncology surgery."
"Imagine if tumor cells can be self-fluorescent 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 knew that this fluorescent staining imaging technology has been applied in some tumor surgeries and has achieved good results.
However, it is currently only an auxiliary means to assist the surgeon in determining the boundaries of the tumor.
The extent of tumor resection is mainly determined subjectively by the surgeon based on various data and experience.
To realize 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 that can accurately detect and quantify the content and location of contrast agents in tumor tissue.
Yu Zhiming nodded softly and said: "Indeed, once this technology is developed, I will no longer need to mark cancerous tissues."
Feng Haiqing said with pride: "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 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, "Dr. Yu, I would like to invite you to join my research team to study this tumor fluorescence imaging technology."
"Once there is a qualitative breakthrough in this technology, Dr. Yu, you will be free and no longer have to be bound to tumor surgery."
He said with deep feeling: "Dr. Yu, your ability is unique, which can give you a transcendent status, but on the other hand, it is also a shackles."
"With all kinds of relationships, various requests, and pressures from power, money, etc., when you have to do a job, even if you feel like vomiting and no matter how reluctant you are, sometimes you have to keep doing it.
"
Yu Zhiming deeply agrees with this statement.
He pondered for a moment and said: "Dr. Feng, you and your research team have made great achievements in the research on tumor fluorescence imaging technology. What can I do after joining?"
Feng Haiqing chuckled and said, "Dr. 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."
"First, it takes some time for new technologies to be accepted and trusted. Second, the accuracy of fluorescent contrast agents in identifying tumor cells needs to be further improved."
Feng Haiqing picked up the tea cup and took a sip of water, and then said: "Dr. Yu, you have an unimaginable talent and can accurately identify cancerous tissues."
"Through comparison, we can find out the tissues that the fluorescent contrast agent cannot identify, as well as the tissues that are misidentified, and do in-depth research on the reasons to further improve its identification capabilities."
Yu Zhiming nodded gently.
Feng Haiqing said with joy on his face: "Doctor Yu, have you agreed 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 thing is that there are a lot of things I want to do, but my time is very tight and limited, and I may not be able to find free time in the future."
"I need to make some trade-offs."
Feng Haiqing nodded with understanding and said: "Dr. Yu, once our tumor fluorescence imaging technology achieves a major breakthrough, it will not only allow you to get more time for yourself, but also allow you to receive major honors..."
He paused deliberately before continuing: "This is a research result that is enough to win a national science and technology award."
Yu Zhiming smiled and said: "This is indeed a very exciting research project..."
After seeing Doctor Feng off, Yu Zhiming looked at the time and saw that there were still nine minutes until one o'clock noon.
He took the time to sit in his office chair, close his eyes and relax...
In the afternoon, there is still employee welfare physical examination.
Not long after the physical examination, Yu Zhiming discovered a woman who surprised him.
Yu Zhiming detected some foreign objects in the uterus of this 43-year-old woman.
At first he thought it was endometrial disease.
After further investigation, Yu Zhiming discovered that these foreign objects were too regular and had a smooth surface.
He finally determined that they were foreign spheres with a diameter of 0.5 centimeters, and there were as many as seven in number.
Yu Zhiming informed the woman of the discovery, but the woman showed no surprise on her face. She just turned red, thanked her 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 there was a serious problem with his liver without even checking.
Yu Zhiming checked him out, and sure enough, he had cirrhosis of the liver, which was quite serious, and he was not far from the decompensation stage.
After Yu Zhiming finished the examination, he took back his hand and his twin brother, who was 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."
This chapter is not over yet, please click on the next page to continue reading the exciting content! The twin brothers 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: "It will take about two to three years, but in your case, transplantation can still be treated."
As he spoke, Yu Zhiming glanced at his twin brother who looked quite healthy.
Liver transplantation can be carried out by biological donation, and because identical twins have no rejection immune response, they can be said to be the most suitable liver donors.
The twin brother looked at his brother, sighed, and said with a painful look on his face: "Brother, I agree to your conditions."
The twin brother snorted softly and said, "What do you have to worry about? I will donate half of my liver to save you, and all I will get back is what should belong to me."
"I didn't ask you to pay extra compensation."
This is a major inside story. Although Yu Zhiming is very interested in gossip, time is tight and the task is heavy. He doesn't have time to listen to the twins grinding their teeth now.
Yu Zhiming looked at his twin brother and asked, "Are you here for a physical examination too?"
"Yes, lie down quickly."
The twin brother smiled at Yu Zhiming and quickly lay down on the examination bed given by his younger brother.
Yu Zhiming put on a pair of medical gloves and began to examine his twin brother step by step.
But after a while, Yu Zhiming's face darkened, making the twin brother's heart suddenly rise to his throat.
He knew that Yu Zhiming was not good at concealing his expressions, and he could tell the severity of his condition from the changes in his face.
With this gloomy expression, the cancer has not gone away.
"Yu... Doctor Yu, I... have cancer?" The twin brother was so frightened that he could not speak clearly.
Yu Zhiming nodded lightly and said: "Lung cancer, in order to avoid misdiagnosis, you need to go to the oncology department for further examination."
"Lung cancer?"
The twin brother didn't believe it and questioned: "Dr. Yu, I don't have a cough, I don't cough up blood, and I don't feel any discomfort in breathing or pain in my lungs. How come I have lung cancer?"
Yu Zhiming explained: "The clinical symptoms of lung cancer are mainly related to factors such as location, tumor size, tumor type, development stage, whether there are complications, whether tumor metastasis occurs, etc. Usually 5%-15% of lung cancer patients develop lung cancer, and
No symptoms of discomfort.”
Most patients with lung cancer 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 develop lung cancer without any clinical symptoms in the early stages.
The reason why these lung cancer patients do not produce clinical symptoms is that the lesions usually grow at 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.
It is precisely because these lung cancer patients have no symptoms that the diagnosis of lung cancer is delayed and treatment is affected.
This is the case for the twin brothers.
"Doctor Yu, my lung cancer should be in the early stage, right? If you treat it well, it won't be a big problem, right?"
Yu Zhiming said truthfully: "All five lobes of your lungs have cancer, and there are more than one."
"Once symptoms appear, your condition will take a turn for the worse, and the prognosis is not very good."
At this moment, the twin brother interrupted and asked: "Dr. Yu, he has lung cancer, is he unable to donate his liver?"
Yu Zhiming nodded and replied: "In principle, it's impossible."
He looked at his twin brothers, who were both losing their minds at the same time, opened his mouth, and then closed it again.
Some words should not have been said by him.
For example, a younger brother with severe liver cirrhosis may consider donating his lungs to his older brother.
For another example, cancer patients are not allowed to 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, the final result is that there is no possibility of treating the twin brothers at the same time...
At nearly 5:50 in the afternoon, Yu Zhiming finally completed the day's physical examination.
He left the soundproof examination room and found Teacher Qi Yue waiting outside.
"Zhiming, that guy Feng Haiqing is not a good partner, don't agree to him..."
