Wu Hang was overjoyed.
The foreign professor didn't look at it, so he happened to have a microscope lens for himself.
"It's impossible..." Director Chi said to himself subconsciously.
Wu Hang's anxious mood improved a little. At least the director was not particularly angry, but was struggling with the process of obtaining pathological cells.
As for the possibility, I also think it is impossible, but seeing it with my own eyes, it is impossible.
I saw it once. Later, Boss Zheng performed nearly twenty operations, and estimated that he took out twenty pathological cells.
"Boss Zheng, what did you use to get the pathological cells?" Director Chi murmured with his eyes still fixed on the microscope.
"Optical tweezers use the photoelectric effect to remove potentially problematic pathological cells." Zheng Ren smiled slightly and said, "Mr. Wu, cover glass."
Wu Hang immediately covered the slide with a coverslip, doing it very gently, for fear of crushing the pathological cells.
Although he knew that the gap between the slide and the coverslip was not enough to crush the pathological cells, he still subconsciously operated with caution.
The slide was handed to Zheng Ren. Wu Hang glanced at Director Chi and immediately went to sit on the other side, fearing that he would miss any details.
Zheng Ren's hands were very steady. Although the cells were at the μm level, the field of view of the microscope lens still fell directly on the removed cell tissue.
Under the lens, twenty cell tissues are clearly revealed.
From the position of Zheng Ren's main perspective, he first looked at all the cell tissues, and then focused on one of them.
This is a polygonal cell, not a round cell as usually understood. More than a dozen corners make this cell look like a ferocious monster that exists in the end of the world.
The nuclei are large and the nucleoli are obvious.
This is a very typical pathological manifestation of hepatocellular carcinoma.
Director Chi took one look and roughly understood what was going on.
It's just that both Director Chi and Mr. Wu Hang find it strange to look directly at cells.
Seeing fresh cell tissue directly without dehydration, fixation, or staining was so unfamiliar that the two people who had been dealing with pathological tissues all year round were stunned.
According to cytology, it should be the cell tissue of hepatocellular carcinoma, but it looks so strange
The polygonal outer cell membrane is still trembling, like a living tissue, a sinister spirit.
One horn waved slightly, as if touching the lens of a microscope, and then the horn penetrated the lens and stabbed into the eye.
Wu Hang jumped and raised his head suddenly.
This is just like watching a horror movie, even IMAX or 3D surround.
The feeling that my eyes were about to be pierced just now was very real.
He wiped the non-existent sweat on his forehead, his heart still beating.
Wu Hang sneered. What he usually sees are specimens that have been dehydrated, fixed, and dyed like mummies. Suddenly the specimen became alive, just like a mummy coming to life.
It was because he was having too much inner drama. When he saw Boss Zheng and Director Chi concentrating on observing pathological cells through the microscope, he felt a little ashamed.
Zheng Ren's hand moved slightly occasionally, while Director Chi looked like the hardest-working and most focused student, with his eyes firmly attached to the lens of the microscope, motionless.
Wu Hang immediately went back to take a look. He didn't want to miss the opportunity to observe living cells.
After mentally building up, I felt much better when I saw the strange-shaped cell membranes shaking slightly.
Being able to take out living cells without even damaging the cell membrane, Boss Zheng is awesome!
As Wu Hang watched, he pondered the two beams of light just now.
The two light beams were like two invisible fingers, taking away cells lightly without leaving a trace.
one…
two…
ten…
Observed one by one, 80% are pathological tissue cells, and the remaining 20% are normal cells.
Suddenly, a cylindrical cell appeared in the field of vision.
Zheng Ren asked: "Director Chi, is this a pathological change of cholangiocarcinoma?"
"Well, it's cylindrical. If there are other cells, you can see them arranged side by side. The nucleus is not as big as that of hepatocellular carcinoma, and is similar to the normal nucleus, but it is deformed."
Director Chi said in a deep voice.
"The patient was diagnosed with mixed hepatocellular and bile duct cell liver cancer." Zheng Ren stopped looking, directly removed his eyes from the microscope, and said calmly.
"There are a few more, Boss Zheng." Director Chi obviously didn't get enough.
"There is no need to look at it. It is basically certain that cells can be taken out with optical tweezers to determine whether it is cancer." Zheng Ren said with a smile, "It's good to know. If you look at the microscope for a long time, the vestibular nerve will have abnormal bioelectrical reflections. I'm starting to feel sick now."
“…”
Director Chi raised his head, and only then did he realize that the person in front of him was not a pathology expert.
He is a doctor in the interventional department.
"Boss Zheng, how did you get the cells?" Director Chi asked: "This method is not used clinically by you, but it is a treasure for our pathology department."
"Optical tweezers, a first-generation product, use the photoelectric effect to individually pick up cell tissues." Zheng Ren smiled, "There is a patient who I suspect has vertebral body metastasis, but it is in a latent state, and existing imaging examinations cannot detect it. Clear diagnosis.”
Director Chi frowned in thought.
"So I want to use optical tweezers to remove pathological cells."
"Are you going to prepare a needle biopsy, or use a special instrument to take cells directly from the patient's suspected lesion?" Director Chi asked.
"Just a puncture is enough to remove a little bit of bone. It won't cause bleeding. Damage at the μm level can't touch blood vessels." Zheng Ren answered confidently.
"Sigh." Director Chi rubbed his temples with both hands, sighed softly, and said, "I also know about optical tweezers. I thought it would take at least 20 years to enter clinical practice or pathological examination. I will never be able to see them in this life. ”
"Unexpectedly, Boss Zheng has already started to contact me."
"It just so happened that I was forced to do nothing." Zheng Ren smiled and began to disassemble the optical tweezers equipment.
"Being able to manually remove pathological cells is really a miracle." Wu Hang whispered to the side.
Zheng Ren ignored Wu Hang. He felt that Director Chi's gaze was like a knife, sharp and sharp.
As if his treasure had been touched, Zheng Ren felt that Director Chi was going to fall out with him.
But this has nothing to do with Director Chi. The optical tweezers belong to me.
Under Director Chi's gaze, Zheng Ren took off the optical tweezers pendant, put it in the box, and then smiled, "Sorry to bother you, thank you."
Bow, turn around, and leave.
Director Chi was speechless for a long time as he watched Zheng Ren and Professor Rudolf Wagner leaving.
"Director." Wu Hang whispered from the side.
"Look at Boss Zheng, he's not even thirty yet! Why can't you get a set of optical tweezers equipment!" Director Chi felt regretful and vented all his anger on Wu Hang.
Wu Hang thought to himself, can it be the same
"Director, why are you back?" He immediately changed the subject.
"..." Director Chi was stunned for a moment, and then said hurriedly: "I left my ID card in the cabinet, and I came back to get it. It's over, it's over, my wife is still waiting for me..."
