Wu Hang was overjoyed.

This foreign professor didn't watch it, and just took a free time to give himself a microscope.

"It's impossible..." Director Chi said subconsciously to himself.

Wu Hang was feeling a little nervous, and the director was at least not particularly angry, but was struggling with the process of retrieving pathological cells.

As for the possibility that it is impossible, I think it is impossible, but what I saw with my own eyes is impossible.

I saw it once, and then Boss Zheng did nearly twenty operations, and probably took twenty pathological cells.

"Boss Zheng, what do you use to get the pathological cells?" Director Chi asked in his mouth while his eyes were still stuck on the microscope.

"Optical tweezers, use photoelectric effect to retrieve possible pathological cells." Zheng Ren smiled slightly and said, "Mr. Wu, coverslip."

Wu Hang immediately covered the slide with a coverslip, making his hands and feet lightly, 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 and carefully operated it.

The slide was handed over to Zheng Ren, and Wu Hang looked at Director Chi and immediately sat down on the other side, afraid that he would miss any details.

Zheng Ren's hands were very stable. Although other cells were viewed directly on the cell tissues that were taken out by the microscope.

Under the lens, twenty cell tissues were clearly visible.

Zheng Ren made the main perspective, he first looked at the cell tissues uniformly, and then placed his vision on one of them.

This is a polygonal cell, not a circular cell that you usually understand. More than a dozen horns make this cell look like a hideous monster that exists in the end of the world.

The nucleus is large and the nucleolus is obvious.

This is a very typical pathological manifestation of hepatocellular carcinoma.

Director Chi took a look and probably understood what was going on.

But whether it is Director Chi or Mr. Wu Hang and Mr. Wu, they feel that looking directly at the cell is unfamiliar.

Without dehydration, fixation, or dyeing, fresh cell tissues are directly seen. It is so strange that two people who have been dealing with pathological tissues for many years are stunned.

According to cytology, it should be the cell tissue of hepatocytes and liver cancer, but it looks so strange?

The polygonal outer membrane is still trembling, like a nasal tissue and a vicious evil spirit.

A corner waving slightly, as if it touched the lens of a microscope, and then the angle was about to penetrate the lens and stab into the eyes.

Wu Hang jumped and looked up suddenly.

This is just like watching a horror movie, and it is even ix, 3D three-dimensional surround.

The feeling of my eyes being pierced just now was very real.

He wiped the sweat that did not exist on his forehead, and his heart was still jumping.

Wu Hang laughed, and what he usually sees are dehydrated, fixed, and stained specimens like mummies. Suddenly the specimens became fresh, just like mummies came alive.

It was because he had too many inner thoughts. He felt a little ashamed when he saw Boss Zheng and Director Chi concentrating on observing pathological cells through a microscope.

Zheng Ren's hand occasionally moved slightly, while Director Chi seemed to be the most dedicated and focused student, his eyes tightly pressed against the microscope lens without moving.

Wu Hang went back to see it immediately, and he didn't want to miss the opportunity to observe ** cells.

After psychological construction, I feel much better when I see the strange-shaped cell membrane shaking slightly.

It is possible to remove living cells without even the cell membrane being damaged. Boss Zheng is amazing!

While looking, Wu Hang thought about the two light columns just now.

The two light columns were like two invisible fingers, lightly taking away cells 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 view.

Zheng Ren asked: "Director Chi, is this a pathological change in cholangiocellular carcinoma?"

"Well, cylindrical, if there are other cells here, you can see them lined up side by side. The nucleus is not as big as hepatocyte and liver cancer, and is similar to the normal nucleus, but has variants."

Director Chi said in a deep voice.

"The patient diagnosed liver cells and cholangiocellular hybrid liver cancer." Zheng Ren stopped looking at it and directly removed his eyes from the microscope and said lightly.

"There are a few more, Boss Zheng." Director Chi obviously didn't enjoy watching it.

"There is no need to look at it. It is basically certain that the cells can be taken by using optical tweezers to determine whether it is cancer." Zheng Ren smiled, "It's good if you know. After watching the microscope for a long time, the vestibular nerve will have abnormal bioelectric reflexes. I'm already starting to feel nauseous."

“…”

Director Chi raised his head, and only then did he realize that the person in front of him was not a great figure in pathology.

They are doctors in the interventional department.

"Boss Zheng, how did you get the cells?" Director Chi asked: "You can't use this method in clinical practice, but for our pathology department, it's a treasure."

"Optical tweezers, the first generation product, use photoelectric effect to separate cell tissues." Zheng Ren smiled, "There is a patient who I suspect has vertebral metastasis, but is in a latent state. The existing imaging examination cannot provide a clear diagnosis."

Director Chi frowned and pondered.

"So I want to use optical tweezers to get pathological cells."

"Are you preparing for a puncture biopsy, or do you use a special device to directly retrieve cells from the part where the patient suspected of the disease?" Director Chi asked.

"Just puncture, take a little bone mass and will not cause bleeding. Other injuries will not touch the blood vessels." Zheng Ren replied confidently.

"Oh." Director Chi rubbed his hands on his temples, sighed softly, and said, "I also understand the optical tweezers. I thought it would take at least 20 years to enter the clinical or pathological test, and I would never see it in my life."

"I didn't expect that Boss Zheng had already started contacting him."

"It happened that I was forced to do nothing." Zheng Ren smiled and began to break down the optical tweezers equipment.

"It's really a magical operation to be able to manually retrieve pathological cells." Wu Hang whispered.

Zheng Ren ignored Wu Hang. He felt Director Chi's gaze as sharp and sharp as a knife.

As if he had touched his baby, Zheng Ren felt that Director Chi was going to turn against him.

But this has nothing to do with Director Chi, the optical tweezers are my own.

Zheng Ren took off the optical tweezers under Director Chi's gaze, took the optical tweezers and took them into the box. Then he smiled, "Sorry, I'm disturbed, thank you."

Bow, turn, and leave.

Director Chi was speechless for a long time when he looked at the departure of Zheng Ren and Professor Rudolph Wagner.

"Director." Wu Hang whispered.

"Look at Boss Zheng, it's less than thirty! Why can't you get a set of optical tweezers?" Director Chi felt regretful and vented all his anger on Wu Hang.

Wu Hang thought, can that be the same?

"Director, why are you back?" He immediately changed the subject.
