Chapter 764 Don’t Promise Him
Feng Haiqing picked up the teacup and took a sip. After putting it down, he slowly asked, "Doctor Yu, how much do you know about tumor fluorescence staining imaging?"
Tumor fluorescence staining is a new type of tumor detection technology that uses the specific binding of fluorescent dyes to tumor cells to make tumor cells show obvious fluorescent signals under a microscope and corresponding imaging equipment.
This technology can be used during surgery to help doctors more accurately remove tumor tissue through color display, reducing surgical risks and incomplete resection.
Because this new technology is mainly used in tumor detection and some tumor resection operations, Yu Zhiming, as a diagnostic doctor, has a general understanding of this technology.
He replied matter-of-factly, "I know a little bit."
Feng Haiqing smiled gently and said, "Doctor Yu, fluorescent staining imaging technology is the direction of development in tumor surgery."
"Imagine if tumor cells could fluoresce or emit light, doctors could more accurately locate tumor lesions, positive lymph nodes, and satellite metastases, achieving complete resection of solid tumors."
Yu Zhiming knew that this fluorescent staining imaging technology had been used in some tumor surgeries and had 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 multiple data and experience.
To achieve the ideal application state mentioned by Dr. Feng, at least two further innovative results are needed.
The first is an injectable, highly sensitive fluorescent contrast agent that selectively accumulates 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 fully developed, I won't be needed to mark cancerous tissue anymore."
Feng Haiqing said proudly, "Doctor Yu, the fluorescent contrast agent and imaging equipment my team and I developed are now comparable in overall performance to those 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, "Doctor Yu, I would like to invite you to join my research team to study tumor fluorescence imaging technology together."
"Once this technology achieves a qualitative breakthrough, Dr. Yu, you will be freed and no longer be confined to tumor surgery."
He added with deep feeling, "Doctor Yu, your ability is unique. This allows you to attain a transcendent status, but conversely, it can also be a shackle."
"There are all kinds of personal connections, all kinds of requests, and pressure from power, money, and so on. When a job is absolutely necessary, even if you feel like vomiting and are reluctant, sometimes you have to do it."
Yu Zhiming deeply agrees with this statement.
He pondered for a moment and said, "Doctor Feng, you and your research team have achieved considerable success in tumor fluorescence imaging technology. What can I contribute if I join you?"
Feng Haiqing laughed and said, "Doctor Yu, there are so many things you can do after joining us."
"Currently, this fluorescence imaging technology is only an auxiliary marking method. During tumor surgery, the surgeon's judgment is still mainly dependent on his experience."
"First, it takes 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 teacup and took a sip of water, then continued, "Doctor Yu, you have an incredible talent. You can accurately identify cancerous tissue."
"Through comparison, we can identify tissues that fluorescent contrast agents cannot identify, as well as tissues that are misidentified, conduct in-depth research on the causes, and further improve its recognition capabilities."
Yu Zhiming nodded slightly.
Feng Haiqing said with delight, "Doctor Yu, have you accepted 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 so many things I want to do, but time is very limited, and I'm not sure I'll be able to find free time in the future."
“I need to make some trade-offs.”
Feng Haiqing nodded in understanding and continued, "Doctor Yu, if we achieve a major breakthrough in our tumor fluorescence imaging technology, not only will you have more time to yourself, but you will also receive significant honors..."
He paused deliberately before continuing, "This is a research achievement worthy of a national science and technology award."
Yu Zhiming smiled and said, "This is indeed a very exciting research project..."
After seeing off Dr. Feng, Yu Zhiming looked at the time and saw that there were still nine minutes until 1 p.m.
He took the time to sit in his office chair and close his eyes to rest...
In the afternoon, we will still conduct employee welfare check-up.
Not long after the physical examination, Yu Zhiming saw a woman who surprised him.
Yu Zhiming found some foreign objects in the uterus of the 43-year-old woman.
He initially thought it was an endometrial lesion.
After further investigation, Yu Zhiming found 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 cm, and there were as many as seven of them.
Yu Zhiming informed the woman of his findings, but she showed no surprise. Instead, she blushed, muttered a thank you, and hurried away.
Around five o'clock in the afternoon, a pair of male twins in their forties arrived at Yu Zhiming's examination room.
One of the men had jaundice on his face, and Yu Zhiming could tell without any examination that he had serious liver problems.
When Yu Zhiming examined him, he found that he had liver cirrhosis, and it was quite serious, and he was not far from the decompensation stage.
After Yu Zhiming finished the examination and withdrew his hand, 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."
The twin brother breathed a sigh of relief and asked again, "Doctor Yu, in my condition, how long can I live?"
"Doctor Yu, please be frank."
Yu Zhiming said frankly: "About two to three years. But in your case, you can still get a transplant."
As he spoke, Yu Zhiming glanced at his twin brother who looked quite healthy.
Liver transplantation can be done through living donors, and because they are identical twins, there is no rejection immune response, so they can be said to be the most suitable liver donors.
The twin brother looked at his brother, sighed, and said with a painful expression: "Brother, I agree to your conditions."
The twin brother snorted and said, "Why should you be miserable? I'm going to donate half of my liver to save you. What you get back is what should have been mine."
"I didn't ask you to pay extra compensation."
There was something important going on here. Although Yu Zhiming was quite curious, time was tight and the task was heavy. He didn't have time to listen to the twins' grumbling.
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 that his younger brother had vacated.
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, and his twin brother's heart instantly rose to his throat.
He knew that Yu Zhiming was not good at concealing his expression, and he could tell the severity of his illness from the changes in his face.
Judging from this gloomy expression, it is definitely cancer.
"Doctor Yu... Doctor Yu, I... have cancer?" The twin brother was so scared that he couldn't speak clearly.
Yu Zhiming nodded gently and said, "To avoid misdiagnosis of lung cancer, you need to go to the oncology department for further examination."
"Lung cancer?"
The twin brother didn't believe it and questioned, "Doctor Yu, I don't have a cough, I don't have blood, I don't have any breathing difficulties, and my lungs don't hurt. How can I have lung cancer?"
Yu Zhiming explained: "The clinical symptoms of lung cancer are mainly related to factors such as the location of the tumor, tumor size, tumor type, development stage, the presence of complications, and whether the tumor has metastasized. Usually, 5%-15% of lung cancer patients do not have any discomfort symptoms."
Most lung cancer patients will have typical clinical symptoms, such as cough, hemoptysis, chest tightness and shortness of breath, weight loss, fever, difficulty breathing, 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 at the edge of the lungs and do not cause erosion damage to structures such as the hilar blood vessels, nerves, and main bronchi.
At the same time, the lung cancer lesions were relatively small and did not cause serious complications such as secondary lung infection or metastasis.
These lung cancer patients have no symptoms, which leads to delayed diagnosis of lung cancer and affects treatment.
This is the case with my twin brother.
"Doctor Yu, my lung cancer should be in the early stages, right? With proper treatment, it shouldn't be a big problem, right?"
Yu Zhiming spoke frankly, "All five of your lungs have cancer, and there's more than 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. Does that mean he can't donate his liver?"
Yu Zhiming nodded and replied, "In principle, it is not possible."
He looked at his twin brothers who were both distraught, opened his mouth, and then closed it again.
There are some words that he shouldn't say.
For example, a younger brother with severe liver cirrhosis can consider donating his lungs to his older brother.
For example, in principle, cancer patients cannot donate major organs to others, but the circumstances of these two people are special.
They are identical twins. The older brother's lung cancer has not yet metastasized, but the younger brother's condition is very bad.
Liver transplantation is still possible.
But no matter what, in the end, it was impossible for these twin brothers to be treated at the same time...
At around 5:50 in the afternoon, Yu Zhiming finally completed the day's physical examination.
He came out of the soundproof inspection room and found Teacher Qi Yue waiting outside.
"To be clear, Feng Haiqing is not a good partner. Don't agree to his request..."
