Chapter 1396

Wu Hang was overjoyed.

The foreign professor didn't look at it. He just had time to give himself a microscope lens.

"Impossible..." director Chi said to himself subconsciously.

Wu Hang's uneasy mood was better. At least the director was not particularly angry, but was tangled in the process of taking pathological cells.

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

I saw it once. Later, boss Zheng did nearly 20 operations. It is estimated that he took 20 pathological cells.

"Boss Zheng, what did you use to get the pathological cells?" Director Chi's eyes were still clubbed on the microscope and murmured.

"Optical tweezers use photoelectric effect to take pathological cells that may have problems." Zheng Ren smiled and said, "Mr. Wu, cover the glass."

Wu Hang immediately covered the slide with a cover glass and walked lightly for fear of crushing the pathological cells.

Although he knew that the gap between the slide and the cover glass was not enough to crush pathological cells, he subconsciously operated with care.

The slide was handed to Zheng Ren. Wu Hang glanced at director Chi and immediately went to the other side to sit down for fear of missing any details.

Zheng Renshou is very stable, although μ For M-level cells, the vision of the microscope lens still falls directly on the removed cell tissue.

Under the lens, 20 cell tissues are clearly displayed.

Zheng Ren made the position of the main perspective. He first looked at the cell tissue uniformly, and then put his vision on one of them.

This is a polygonal cell, not a round cell as usually understood. More than a dozen horns make the cell look like a ferocious monster like 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 both director Chi and general manager Wu Hang feel strange to look directly at cells.

Without dehydration, fixation and staining, you can directly see the fresh cell tissue. It is so strange that two people who have been dealing with pathological tissues for many years were stunned.

According to cytology, it should be the cell tissue of hepatocellular carcinoma, but it looks so strange?

The polygonal extracellular membrane is still shaking, like a living tissue, a vicious spirit.

One corner waved slightly, as if it touched the lens of the microscope, and then the corner would penetrate the lens and stab into the eyes.

Wu Hang jumped and suddenly looked up.

It's the same as watching horror movies, even IMAX and 3D surround.

The feeling that your eyes are about to be pierced is very real.

He wiped the sweat that didn't exist on his forehead, and his heart was still beating.

Wu Hang smiled. What he usually saw were dehydrated, fixed and stained specimens like mummies. Suddenly the specimen became fresh, just like a mummy.

He was ashamed to see boss Zheng and director Chi concentrate on observing pathological cells through a microscope.

Zheng Ren's hand occasionally moved slightly, while director Chi was like the most hardworking and focused student. His eyes were tightly attached to the lens of the microscope and did not move.

Wu Hang went back to see it immediately. He didn't want to miss the opportunity to observe living cells.

With psychological construction, I feel much better when I see the strange shape of the cell membrane shaking slightly.

You can take out living cells without damaging the cell membrane. Boss Zheng is powerful!

Wu Hang looked and pondered the two light pillars just now.

The two light columns are like two invisible fingers, which take away the cells without leaving a trace.

One

Two

Ten

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 the pathological change of cholangiocarcinoma?"

"Well, it's cylindrical. If there are other cells, you can see that they are arranged side by side. The nucleus is not as large as that of hepatocellular carcinoma. It's about the same as that of normal nucleus, but there are variants."

Director Chi said in a deep voice.

"The patient diagnosed mixed hepatocellular and cholangiocytic liver cancer." Zheng Ren also stopped looking, directly removed his eyes from the microscope and said faintly.

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

"There's no need to see it. It's basically determined that cells can be taken with optical tweezers to determine whether it's cancer." Zheng Ren said with a smile, "it's good to know. After watching under the microscope for a long time, there will be abnormal bioelectric reflex in the vestibular nerve. Now I'm beginning to feel sick."

“……”

Director Chi raised his head. At this time, he realized that this man in front of him was not a big bull in pathology.

He's an interventional doctor.

"Boss Zheng, how did you get the cells?" Director Chi asked, "you can't use this method clinically, but it's a baby for our pathology department."

"Optical tweezers, a generation 1 product, use photoelectric effect to clamp cell tissue alone." Zheng Ren smiled. "There is a patient who I suspect has vertebral metastasis, but it is in a latent state. The existing imaging examination can not give a clear diagnosis."

Director Chi frowned and mused.

"So I want to take pathological cells with optical tweezers."

"Are you going to take a biopsy, or do you take cells directly from the patient's suspected lesions through special instruments?" Director Chi asked.

"Puncture is OK. Take a little bone and it won't cause bleeding. μ M level of damage, still can't touch the blood vessels. " Zheng Ren's confident answer.

"Alas." Director Chi rubbed his hands on his temples, sighed gently and said, "I also know about optical tweezers. I thought it would take at least 20 years to enter clinical or pathological examination. I can't see it in my life."

"Unexpectedly, boss Zheng has begun to contact."

"By chance, I was forced to do it." Zheng Ren smiled and began to disassemble the optical tweezers.

"It's a divine operation to manually take pathological cells." Wu Hang whispered a sentence on one side.

Zheng Ren ignored Wu Hang. He felt director Chi's eyes like a knife, sharp and sharp.

Like touching his baby, Zheng Ren felt that director Chi wanted to turn against himself.

But this has nothing to do with director Chi. The optical tweezers are his own.

Under director Chi's gaze, Zheng Ren took off the optical tweezers pendant, received it in the box, and then smiled, "excuse me, excuse me, thank you."

Bow, turn and leave.

Looking at the figure of Zheng Renhe and Professor Rudolph Wagner leaving, director Chi was speechless for a long time.

"Director." Wu Hang whispered in one side.

"Look at boss Zheng, it's less than 30! Why can't you get a set of optical tweezers!" Director Chi felt sorry and vented his anger on Wu Hang.

Wu Hang thought, can it be the same?

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

"..." director Chi was stunned and hurriedly said, "I left my ID card in the cabinet. I came back to get it. After that, my daughter-in-law is still waiting for me..."
