Wu Hang was overjoyed.
This foreign professor did not look at it. He just happened to have a microscope for himself.
"That's impossible …" Chief Chi subconsciously muttered to himself.
Wu Hang's nervous mood improved a little. At least the chief was not particularly angry. Instead, he was conflicted about the process of taking the pathological cells.
As for whether it was possible or not, he also thought it was impossible. However, he saw it with his own eyes. How could it be impossible?
He saw it once. Later, Boss Zheng did nearly twenty operations. He estimated that he took twenty pathological cells.
"Boss Zheng, what did you use to take the pathological cells?" Chief Chi's eyes were still on the microscope as he muttered.
"Optical tweezers. I used the photoelectric effect to take out pathological cells that might be problematic." Zheng Ren smiled slightly and said, "Chief Wu, the coverslip."
Wu Hang immediately used the coverslip to cover the slide. He was careful, afraid that he would crush 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 carefully.
The slide was handed to Zheng Ren. Wu Hang glanced at Chief Chi and immediately went to sit down on the other side, afraid that he would miss any details.
Zheng Ren's hands were very steady. Although he was looking at other cells, the microscope's field of vision still fell directly on the cell tissue that was taken out.
Under the lens, twenty cell tissues were clearly visible.
Zheng Ren was in the position of the main perspective. He first looked at the cell tissues in unison, then focused his field of vision on one of them.
This was a polygonal cell, not the circular cell that was usually understood. The dozen or so horns made this cell look like a ferocious monster that existed in the apocalypse.
The cell nucleus was large, and the nucleolus was obvious.
This was a very typical pathological manifestation of hepatocellular carcinoma.
Chief Chi took a look and roughly understood what was going on.
However, whether it was Chief Chi or Chief Wu, they all felt that looking directly at the cell was very unfamiliar.
Without dehydration, fixation, and staining, they directly saw the fresh cell tissue. It was so unfamiliar that the two people who had dealt with pathological tissues all year round were stunned.
According to cytology, it should be the cell tissue of hepatocellular carcinoma, but why did it look so strange?
The outer membrane of the polygonal cells was still trembling, like a monster tissue, a fierce demon.
One of the horns waved slightly, as if it had touched the lens of a microscope. Then, the horn was about to penetrate the lens and pierce into the eye.
Wu Hang was shocked and suddenly raised his head.
It was like watching a f * cking horror movie, the kind that had IX and 3D surround.
The feeling of his eyes being pierced was very real.
He wiped the non-existent sweat from his forehead, his heart still beating fast.
Wu Hang smiled sheepishly. What he usually saw were specimens that were dehydrated, fixed, and dyed like mummies. Suddenly, the specimen became alive, as if the mummy had come to life.
It was because he had too many inner thoughts. When he saw Boss Zheng and Chief Chi focusing on observing the pathological cells through the microscope, he felt a little ashamed.
Zheng Ren's hand moved slightly occasionally. Chief Chi was like the most hardworking and focused student. His eyes were glued to the microscope lens and he did not move at all.
Wu Hang immediately went back to take a look. He didn't want to miss the opportunity to observe the fat cells.
Now that he had mentally prepared himself, he felt much better when he looked at the slightly shaking oddly shaped cell membranes.
To be able to take out living cells without even damaging the cell membrane, Boss Zheng was amazing!
As Wu Hang watched, he pondered over the two pillars of light.
The two beams of light were like two invisible fingers, easily taking away the cells without leaving a trace.
One …
Two …
Ten …
After careful observation, 80% of the cells were pathological tissue cells, and the remaining 20% were normal cells.
Suddenly, a cylindrical cell appeared in his field of vision.
"Chief Chi, is this the pathological change of cholangiocarcinoma?"
"Well, cylindrical. If there are other cells, you can see them arranged side by side. The cell nucleus is not as large as that of hepatocellular carcinoma. It is similar to a normal cell nucleus, but there are variants. "
Director Chi said in a deep voice.
"The patient is diagnosed with hepatocellular and cholangiocarcinoma," Zheng Ren said faintly as he moved his eyes away from the microscope.
"There are a few more, Boss Zheng." It was obvious that Chief Chi had not seen enough.
"There's no need to look anymore. It's basically confirmed that we can use the optical tweezers to remove the cells to determine whether or not it's cancer." "It's good that you know. If you look under the microscope for a long time, the vestibular nerve will have an abnormal bioelectric reaction. I'm starting to feel disgusted now."
"…"
Chief Chi raised his head. Only then did he realize that the person in front of him was not a great figure in pathology.
He was an interventional surgeon.
"Boss Zheng, how did you take the cells?" Chief Chi asked. "You can't use this kind of method in the clinic, but for our pathology department, it's a treasure."
"Optical tweezers, a first-generation product, use the photoelectric effect to separately clip the cell tissue." Zheng Ren smiled. "There's a patient who I suspect has a vertebral body metastasis, but it's in a latent state. The current imaging examination can't give a clear diagnosis."
Chief Chi frowned and pondered.
"So I want to use the optical tweezers to take the pathological cells."
"Are you going to perform a puncture biopsy, or are you going to use a special instrument to take the cells directly from the patient's suspected lesion?" Chief Chi asked.
"A puncture will do. Take a little bone and won't cause bleeding. Other injuries won't touch the blood vessels, "Zheng Ren answered confidently.
"Sigh." Chief Chi rubbed his temples with both hands and sighed softly. "I also know a little about optical tweezers. I thought that it would take at least 20 years to enter the clinic or pathology. I won't be able to see it for the rest of my life."
"I didn't expect Boss Zheng to have already started to come into contact with it."
"Coincidentally, I was forced to do so," Zheng Ren said with a smile and began to disassemble the optical tweezers device.
"It's really amazing to be able to manually remove the pathological cells," Wu Hang muttered softly at the side.
Zheng Ren ignored Wu Hang. He felt that Chief Chi's gaze was like a knife, sharp and fierce.
It was as if he had touched his treasure. Zheng Ren felt that Chief Chi was going to fall out with him.
However, this had nothing to do with Chief Chi. The optical tweezers were his.
Under Chief Chi's gaze, Zheng Ren took off the optical tweezers pendant and put it in the box. Then, he smiled. "Sorry to disturb you. Thank you."
He bowed, turned around, and left.
Chief Chi was speechless for a long time as he watched Zheng Ren and Professor Rudolph Wagner leave.
"Chief," Wu Hang whispered from the side.
"Look at Boss Zheng. He's not even 30 years old! Why can't you get a set of optical tweezers? "Chief Chi felt pity in his heart and vented all his anger on Wu Hang.
Wu Hang thought to himself, 'How can that be the same?'
"Chief, why are you back?" He immediately changed the topic.
Chief Chi was stunned. Then, he hurriedly said, "I left my ID card in the cabinet. I came back to get it. It's over. My wife is still waiting for me … "
